Numitron backing is grey because RCA used what they had in spades, the sheet steel with aluminium coat that was used to make anodes and internal structures for thermionic tubes, and this was proven to survive the glass sealing and gettering operations. Thus they used the standard tools they had in the tube plant, the flat anode sheet, slightly formed to be a stiff backing, and punched out the holes needed to hold the filaments. Then used the technology they had to make glass beads with wire in them, and sealed those into the holes, making the filament supports, and then simply used a flat section of that steel wire that was bent over to hold a length of thoriated filament wire, also a common item in the tube shop. Length and diameter calculated for the brightness needed at the applied voltage, and then simply placed in location, the ends folded over, then spot welded together to trap the tungsten wire under slight tension. Then at the rear spot welds to a lead frame attached to a standard off the shelf 9 pin glass base, and you have the complete unit. Glass top attached, and then evacuated with the standard roughing pump, and as a bonus because of the low voltage, and no need to maintain an ultra low vacuum, the roughing pump and the heat sealing of the tube is all that is needed to operate, no need for a getter to be installed, and no need to flash it, just a RF heating during sealing to get a high vacuum, then seal.
Incidentally there were small versions made, the same size as your common 7 segment LED displays, and they were very popular, as they ran off 5V, and interfaced with logic. They worked best using CD4049/50 CMOS level shifting buffers, as those would source or sink 50mA no problem. Using a buffer/inverter per lamp, and a BCD decoder or counter per digit allowed those displays to be bright, and as bonus you could also use the blanking input on the drivers to use PWM to dim them.
Project to replace those displays with LED ones worked, just that it really did not drop display current use, it was still 5A of current at 5V, though it was good in that at least you had a display that now was available, using a tiny HP 7 segment red display. Do one conversion and you had 16 numitron displays to use to fix others, so we only converted 3 boards to the LED version. Biggest problem was the resistor value selected was too low, so the LED displays were running way too bright, so had to be dimmed. Rather than destroying the cordwood board made to fit them, I simply used 2 6A silicon diodes in the common line, to drop the voltage seen by the LED displays down from 5V to 3V8, which made them dim to exactly match the old displays. Those 2 diodes were hard to fit in the limited space left on the display board. Users liked the new crisp displays, the bright version got complaints that it was so bright it was unreadable at night with dark adapted sight, and it lit up the entire cockpit. Display dimming had to match the other display, and that board used unijunction transistors, and had a disconcerting habit of the power transistor unsoldering itself from the wire leads, it ran so hot. Base lead unsolders itself, transistor is still conducting, runs hotter and lamp blows. Select spare lamp and it also blows, unless enough time for transistor to cool below 200C junction temperature. Would have been nice to have had some of the more modern mosfets that can handle 50A, but not at the age of that design.

Grey coating is an insulator, to prevent circulating currents through the bearings from any slight imbalance in magnetic field in the motor. there is a single bearing that is grounded ( the shiny one) to prevent charge build up on the rotor and a flash over to the frame, but the rest have to be insulated so they do not have a shorted turn through the frame that can cause a high circulating current through the bearings that rapidly erodes them through arcing. There are current paths for this current via things like the output shafts and the selector forks, but they probably assumed that, being long thin wall section steel assemblies, this long path would both keep the current low enough not to cause any major extra wear, and also the long output shaft would be mostly self cancelling field wise as well.
A lot of larger electric motors handle this with one end having coated bearings, or they make them with ceramic bearing balls inside, or just make both sides with insulated bearing mounting frames, and provide a grounding carbon brush assembly to handle shaft grounding. Drawback of the coated bearing is that you have to ensure that there is absolutely no damage to the coating on the outside and the side facing the frame, so that there is no metal to metal path. However, depending on the exact coating applied, this coat can be both insulating and tougher than the steel of the bearing itself. grey would point to a spray on ceramic coating, probably vacuum deposited before final bearing assembly or applied as a plasma coating.

The thing about the photography side was that the ultra fast gas switches were not used to fire the Xenon flash, which, for the technology of the time, was easy to do, using a simple high voltage pulse that ionised the gas in the Xenon flash tube at the cathode end. The big thing was they had to actually only fire the tube for a very brief period, so as to only have this very short burst of very bright light, so that the motion of the aircraft would not blur the image. Thus the need to develop a device that would be able to turn on very fast, and also handle a massive current pulse, so as to dump all the charge in the capacitor bank used to provide energy to light the flash tube, so as to drop the voltage across the flash tube (at this time it would be dropping from the 400V or so initial voltage, to the cut off point of around 60V, where the tube itself would start to slowly cut off due to the arc voltage being below the voltage needed to keep it on, slowly being in the order of tens of microseconds) to close to zero, and thus ensure it has a sharp cut off. Most devices at the time would either not last more than a single use, or would not have the fast response needed.
This device was the original gas thyratron, and the need for fast ones meant they made them with a hydrogen gas fill, with early ones filled with neon being both slow, and too low an operate voltage. Hydrogen gave the needed high voltage stand off needed, and because it is light, it also ionised very fast, giving the very rapid current path build up, in the order of nanoseconds from fully off to fully on. This has led to them being now an export controlled device, and to this day an item that is still made, on the original tube lines, by some specialist companies in the USA, as the US military needs them for operational parts, and, because of the hydrogen gas fill being able to penetrate almost all seals with ease, a part that has a very limited shelf life of around 2 years, before you need to either replace or rebuild it. Neither are cheap either.
You can test it at lower current, and do all your qualification at this level, as full power operation you only have around 5 uses, before it degrades to the point it is no longer usable. Selling them is ITAR restricted, as heavily as any part can be, because of the one use case, so there have been a few attempts to steal the technology. These days you still find it hard to get the same power delivery with small volume, it really is a part that is perfect in it's application. But you can do it, with modern high power semiconductors from specialist companies, with corresponding exotic semiconductor compounds, and prices that make the gold used to plate them the cheapest cost in production.
Incidentally the bridge wires also underwent massive changes, from simple thin wires, to the modern ones, mass produced using semiconductor wafer processes, to make thin film metal alloy strips that are precisely controlled in shape, composition and dimension, so that all of them are as close to atomically identical as possible. The difference in timing between them is in the order of picoseconds, they are that identical.

dislike is the wrong word, i would think that the word detests is a more appropriate one, but Louis is not in Australia, and a flight of 15 hours to get to say it personally is the only thing that prevents him from going personally to his door, and expressing it the Bronx way, with a few woids, followed by a few more woids, followed by the need to find a local park, and go to Bunnings to acquire a pack of Hefty garbage bags, some bleach, and a decent pick and shovel. Then 4 hours of workout in a quiet spot in the park, and following that a thorough clean up of the house. The woids having been said, then he can fly the 15 hours back to his house, nicely relaxed, and able to talk under 200 woids per minute.

Seen the coring team at work once, they were trying to get a sample of the sub base on a road, and had cored down half a metre through layer upon layer of top material, before they finally came to the sub grade layer. That road had been getting layers of top wear course added every few years since it was built, because the ground had subsided a little with time, and the swamp had been drained. Plenty of roads have thick wear courses, because they simply got overlaid with new, and the crown increased, and every decade or so the pavements were relaid higher. Old pictures from the 1930's of the building i lived in had a set of stairs at the front, now the pavement is level with the top step of the building, stairs all buried. Where I currently live 3 steps down from street level, for the same reason.

@alexanderkupke920 Jet A1 is kerosene that has been dewaxed, removing all the longer chain molecules, so that it will not turn to slush at -40C in the aircraft fuel tanks. The wax that is removed is further classified by melting point, so you get soft waxes that melt around 40C or lower, often sold as Vaseline or petroleum jelly, and harder waxes that melt around 70C, which are used to make candles, and as a base for many cosmetics and shoe polish. Higher melting point waxes are also used in industrial applications for various things.
Diesel oil is very close to paraffin or kerosene, just has a somewhat less and slightly different range of melting and boiling points and density. To further confuse things you also have Rocket kerosene, which is a very highly refined Jet A1, that is designed not to freeze till around -100C, and which also has even less wax in it.
In general you can run the diesel vehicle on kerosene, but it will run poorly, as diesel has additives in it to lubricate the fuel system, which is needed, plus the wax will tend to clog fuel lines and injectors as it flows through and undergoes local cooling. Same for a jet engine, which will run on diesel, though it will smoke heavily, as the fuel is not being fully burnt before it leaves the combustion chamber.
Run a modern GDI engine on kerosene and it will very quickly fail, but older mechanical injection engines do not care, and will run on diesel, kerosene, Jet A1 or even vegetable oil, provided you can get it liquid enough to flow through the pump.
Lamp oil can be also a blend, with it consisting of a mix of kerosene, diesel and even lighter oils and benzene to make it light easier, and also can have aromatic oils added to it to have an odour other than the distinct one.

Box is an electrical switch refurbishment kit, which while it is for the water distiller, those switches and parts would have been common throughout the U boat, so that kit would have been used all over, for switch and control maintenance, as the switches are a common ship part, and the ceramic parts used to contain the brass and silver contact blocks, and those do wear with use. That it was in the front was just that it was probably last used in the torpedo room as a tool kit, and then it stayed there, till it would be needed again for the water distillation plant, or there was more need for it at the front, or at least space to store it there, as often tools would be stored all round the ship, where you had a space free.
BBC later on amalgamated with the Swedish Asea group, and then became Asea Brown Boveri, and later on also dropped the names, becoming ABB group. I have used Brown Boveri relays, they are an incredibly popular item in German built equipment, all the way through to this century, as they are both very reliable, and also very robust, with a lot of the relays going well past the rated million cycle guarantee, and some probably went well past the hundred million cycle point before they physically wore out.

DC does not allow smaller cables, it just means you can use the cable at the rated voltage, and do not need to make allowance for the crest factor of the cable. While this is useful on HVDC (150kV or higher) power lines, where you get 40% more power transmitted, for the same current, and the same peak voltage, it makes absolutely no difference for lower voltages, or for anything that is going to be common in industry or homes, where your standard house wire in use has a 1kV rating.
But it is never run even close to this, the only place where you run regular cable at higher voltage is in tunnels, where the supply for lighting and fans is typically 700VAC, as that is a big increase in power transmitted down the tunnel, for the same diameter cable, over using the standard 400VAC 3 phase supplies they normally use. Allows use of standard industrial cables and fittings, rated for 1kV, and also means they can put nearly double the load into the tunnel for lighting and fans, as they now just use either local autotransformers, to provide the local run, or have motors wound for 700VAC operation instead. Saves a lot of money if you do not need to make the tunnel 1m wider, to get the high voltage cables in and still provide the required separation, and also the need to dig big equipment rooms to house the big transformers, as opposed to simply running the cables on the walls, or under the road bed, where they are well protected, plus your control gear is almost all mostly off the shelf of Schneider or ABB, and not too much that needs custom manufacture and certification, as the regular switchgear is already rated in the most part for 1kV use under the Low Voltage directive, Low Voltage here referring to power distribution under 1000V.
DC is common, just that it is typical in Telecoms, where you get a lot of equipment that runs off a nominal -48VDC rail, based on old telephony battery bus voltages, and it is also common in large industrial equipment with a lot of inverter drives, where they use a DC bus to connect all the inverter units, so that energy recovered from the one unit as it slows down a motor can be used by others to power them, instead of being dumped as heat in a brake unit. there you find 400VDC, 600VDC as common bus voltages.
However a big issue is fault protection, as DC rated breakers, fuses and disconnects are quite a lot more expensive and larger over the same rating AC units, as the AC units have no need to break an arc, as it is naturally going to be extinguished twice per cycle, so all the unit has to do is prevent it from striking again, unlike DC units, which actually have to cool it down till it goes and stops, by no longer being able to ionise air. DC you can pull a very large arc, while AC it tends to go out easily. Look up the people doing welding using only solar panels in the sun, nothing else, and that they can draw pretty big arcs out of them, along with solar panel fires that only stop when the sun goes down, or the panels burn out completely.

Well, if you are at home alone, and the cucumbers have gone off, and the bananas are all rotten, and the postman is practising safe zones, so will not come indoors, even with the promise of all the cake he can eat, you need the essentials.
You know that in 9 months, the most important medial profession will be a midwife or obstetrician, and right after this period of stay at home is lifted, you will need one of three professions: Divorce lawyer, Councillor and Gynaecologist.Perhaps all three.
For plastic dick yes the comment section is correct, though with the commenters you cannot be sure if they want one, or want to have one used on them, or want to be one. You can be sure they all want it supersize though.

@masterpython Not likely, they will simply strip out the liner, call line and patient table top, and send that to the incinerator, and put in a new set. The rest will be washed down with a succession of industrial washing agents, starting with plain chlorine bleach at high concentration, then with a bromine based bleach, followed by a cycle of plain detergent washes to remove the first two wash agents, and then a rinse and dry. Patient bedding and mattress straight to the incinerator, and the room will get the same treatment as the MRI. Hospitals do have procedures for this, and many have had exposure to Ebola, and other deadly diseases, and have the protocols in place, and the right cleaning agents in stock.
Surgical instruments pretty much all parts that contact the patient are disposable, and thus they will throw the entire kit away anyway, unless it is some expensive kit, which in that case they will simply replace all parts that contact patient. Things like respirators easy enough to replace all parts the patient breath comes into contact with, part of the regular service kit anyway, and surgical tools they are cheap enough to the hospital that sending them through an incinerator, and billing the insurance, is cheap, as yes they are hard to totally sterilise, especially if there are plastic parts, metal ones you just send through a high pressure autoclave, but even so they are sold as disposable items anyway.

Ethernet won out because the standard was free to use, and also did not need you to pay a license fee per card, unlike some of the competitors, like Token Ring, where you had to pay IBM for it, and Arcnet did not scale as well, even though it did use a very much cheaper cable, but in the end Ethernet would run on the same cables, and being low cost the cards got cheap fast, and of course got used a lot, so the peripherals grew fast, and the cost kept dropping. Still have the crimp tooling for Arcnet, which came in really handy doing CCTV work, as the connectors are almost completely compatible in most cases.

Tupolov has an issue in that a good chunk of the parts come from factories based in Ukraine and Belarus, along with a lot of "western" electronics parts in the avionics and mechanical assemblies, so they are not really able to actually build now, seeing as there is a issue getting delivery. As well the "alternative" parts market also has not only fake and expired parts, but also you have the issue of version mismatches, which can be anything from a needle calibration being different, to a part that works initially, but, because the differences are subtle, you can have it either fail after a few hundred hours, or it can corrupt the data after that time, or just have edge cases that result in a non noticed failure, till it is too late.

Her problem was she did not do this through a string of LLC's registered at a few locations, and used them to buy the stuff. Nobody in the US military would look at under $100 million and care, especially if she kept it under the line budget minimum of $10 million, which simply gets put on the local budget as a single line of "Misc. expenses, total", and then ignored. That would have allowed her to continue for 10 years, get herself all the money she needed to retire on, then go on early pension. Pay the taxes for the LLC's, run them with barely a profit with creative accounting, and pay the IRS a few thousand a year, and the DOD would never have found out.

@Kelvasco Yes the pressure accumulator and switch will help a lot, and to dampen the noise you just need to put the doghouse cover back in place, with the neoprene sound absorber intact, which will go a long way to making it quiet. Hard otherwise to damp it fully, as you need airflow around it to keep it cool. You can use extra rubber mounts and a metal shield to cover the top and bottom, which will help with debris control off road, and this can also have a neoprene rubber layer stuck on to damp sound more as well, but still allow cooling air to flow through. However I will say that the fluid reservoir is a little on the small side to run with an accumulator, it will need to be at least double the volume of the accumulator bladder, so as to keep enough fluid in the system to not suck air.
As well you really want a spin on filter housing, and a hydraulic oil filter in the suction line, so as to keep dirt out of the system. The spin on filter should be there from the original Hummer parts bin, and it will go a long way to keeping the precision hydraulic parts clean. Plenty of chassis space there next to the pump suction line to put the filter in, and it will rarely need changing, just the annual lubrication service for the transmission will involve changing the filter, and topping up the fluid again.

Will also conform that a hard boiled egg, boiled to military cooking specifications, will absolutely shatter a windscreen of a vehicle.The eggs are boiled in a 44 gallon pot, and the process starts with filling it to a quarter of the way with water, then adding in a 2kg bag of salt. Then eggs are started loading, from trays of 60 dozen, and the cooker is turned on full. Eggs are loaded till the top, and then the unit is left till it is boiling vigorously. Then a 20 minute timer is started, and at the end of 20 minutes the power is turned off, and they slowly start to remove the eggs, packing them back into the trays, and back into the boxes. Then off to the walk in cooler.
If you are lucky, you get one from the top of the pot, which only has been cooking for a half hour or so. Unlucky and you get the ones from the bottom, who have been cooking for 2 hours or so. Top ones are edible, bottom ones are black and blue all the way through, from the white to the yolk. They do bounce when dropped out of the bus at speed, and yes somebody did throw one at an approaching vehicle who was driving badly, and it shattered the windscreen.
there is a reason the military cooked were nicknamed fitters and turners. They fitted it into the pot, and turned it into crap not even a pig would eat. Yes some of the messes had pig farmers who took all the surplus food, and sometimes even the pigs would not eat it.

Recipe is useless without the way you do it. Just like making a cake is to take sugar, water, flour, baking powder, eggs, milk and butter, plus some minor ingredients like cocoa, salt and vanilla, but you really have to know how to mix them, and in what order, to make something that will actually look like a cake.

My father was one of those interned pilots, though he did not land there, but rather escaped over the border in a '"borrowed" Adler instead. He was repatriated fast enough to go fly in Africa again and in Burma, after his burns from being shot down had healed. The Austrian hospital he was recovering in is now a hotel, and in the 1980's he went there just to see it. He was thankful to the Austrian people for helping him survive, and for the doctors and nurses who put him back together, after being found under a tree in a snowbank apparently dead.
Helped that he spoke fluent German, just was in Glasgow in 1939, instead of Hamburg, looking to study, plus had a British Colonial passport. he found out in the 1990's just how the one German Ace had shot him down as well, watching Discovery.

My mother had a succession of those, as that suspension is the only thing that could handle the roads of Central Africa, and not break.Yes low and underpowered, but perfect if you wanted to travel around, and that did drive all around, including a few 2600 miles trips, one way, to the coast as well. On roads that only later on even saw tar, and in general which were, at best, unpaved dirt, that possibly had seen a grader in the last decade.

Duracell also made blister packs of cells with the tester in, as discussed. The resistive element is actually screen printed conductive ink, which is based on silver powder, in a carrier based on printing ink, screen printed onto the plastic sheet, and then this thin sheet was dried, and the back had the thermochromic ink screen printed onto it, followed by the top layer being thermally bonded, to make a 2 layer sheet with the tester in it. Then the paper insulator was applied, pre punched out for the gap where the thermal heater needed insulation, and the one hole for the switch, the cutting die finishing separating the paper from it's supply roll. This was then punched out, and applied to the large sheet of battery label on the adhesive side, so you had a large self adhesive label, that had a release side applied, and this again got partly cut out, to leave the battery sleeve on the backing layer, excess being weeded off automatically. Then slit into working rolls, and applied on the line.
Very complex, and needing lots of precision sharp cutting dies, so no wonder they decided the much higher cost and complexity per cell was not worth it. Thus the shift instead to use almost the same test unit, just with 2 strips of adhesive on the top, to the blisters, saving a lot of money, as you only had one per 4,6,8 or 10 cells. Then cost was cut again, and with all the assorted contract manufacturers not wanting to pay the cost, they went back to just labeling generic cells off a random production line, as Duracell is now nothing but a brand name applied to whatever generic cell was the cheapest quote to make a few hundred million cells, no quality required as they are running off name recognition. After all, no longer will they replace or repair equipment damaged by leaking batteries, they will only pay you a voucher for the cost of a new set, if you pay to ship the leaking batteries to them, at your own cost.

Paddles work by resetting both RC circuits at the video vertical blanking interval, and then using a pair of comparators to measure the number of times the horizontal clock was generated. If the voltage went above the threshold on a particular line it set a latch, and enabled another counter that counted lines, and put that as the paddle position, Then the counter that was running to generate horizontal elements on the display would and this. This would go to two places, first to video out, as the paddle, height being a certain number of lines, and also to another and gate that has the horizontal position of the ball, so that if it was in the way the ball would have the direction reversed and returned, and if not it would be classed as a losing ball.
Very simple, and the sound was generated out of internal counter overflows, using the logic for the hit to do the beep, gating in the clock for the paddle display, and for others using other counter outputs and different frequencies.

Funny enough, I did once jump start a helicopter, which had a battery that had run down due to the DC bus being turned on overnight so the security guards could use the aircraft radio to listen to broadcast FM. Helped that I did my apprenticeship on that model, and knew the entire electrical system, and also the pitfalls that could occur with them running the battery down, and what to look for. Ground power unit and the ground power connection, start the ground power unit and power up the DC bus, and they press start.
Low current, the ground support unit is designed to supply 8kA at 28VDC, and this little turbo barely made it to 400A during start, so after a half minute of idle, pulled the cable ( only way, there is no disconnect other than a sense contact on the plug), waited another 5 minutes at idle to see if the battery was not going to go into thermal runaway, it was still cold so gave them a clearance to take off back.
As well used another ground support unit to jump an ambulance that had waited 6 hours for the casevac to get there, with lights on, and there had to grab jumper leads to make the link between the connector and the battery. those lights went very bright on 28V instead of 24, and that ammeter needle did not even budge off the zero during the very very vigorous starting.
As to the LRV batteries being used to fire the ascent stage probably no issue, the batteries certainly were the same chemistry, they used a similar enough voltage. The major issue was the disconnection, as the LRV batteries would stay behind, and the ascent stage needed power to keep the valving operational, so they designed the systems to get you power from an alternate set of ascent batteries if the main ones failed, but use batteries on the ascent stage.
You could not have kept the mass centre stable if you used the LRV battery pack and carried it with, no real space to place it (otherwise they would have had equipment or battery pack there already) and also it would move the mass centre from the engine bell outside the ability of the RCS system to compensate for the eccentricity.
Silver Zinc batteries are heavy, and are only used in space applications because they are so reliable and tolerant to abusive temperatures and charge and discharge use, unlike the modern lithium chemistries. Thus you can have a smaller battery pack for the same high current draw, and not have to worry too much about it cycling from -100C to +200C every orbit.

@RipliWitani Yes, they would, seeing as she has a casino loyalty card, know exactly when she visited, and exactly how much she spent. Almost no casino works on cash, they all work on cards now, because that means they know you will overspend, and the only thing with chips and tokens are the roulette tables, which are still holding out, though there is also being made digital. They know exactly how much she has spent since then, and also probably also have all the video of the intervening time as well stored on some sort of system "just in case".
One casino about to lose their money, and a whole lot of reputation as well, which is the bigger hit, as the only thing they have to get people in is that they are not crooked, because it is rare to only have one casino in any area.

Lamp life is the emissive material on the filament failing, and then also sodium attacking the graduated seal that is there where the seal is, as they go from quartz glass to a softer glass that will handle the leadout wires going through, and also allows the vacuum system to pull all the gas out before introducing the Penning gas mix that provides the initial conduction. That is why your standard operating position is base up, or with the base no more than 15 degrees from horizontal, so the liquid sodium does not get near the filament area, and rapidly erode the glass, as it is a sodium oxide, so will dissolve in sodium, unlike the fused silicon dioxide of the rest of the arc tube.
Warm up time is because you have to heat up the inner tube to the point the sodium inside turns to vapour, which is the yellow emission, and the indium oxide coating on the inner surface of the glass envelope and the outside of the quartz tube is there to reflect the IR energy back to the tube.
Ballast is an autotransformer ballast with a tuned circuit in it, and likely the capacitors in there have changed value from self healing, and should be replaced. Identical value polyester motor run capacitors, one by one, and the power factor will improve, especially as the lamp warms to full brightness, and should land up at around 0.85 lagging when on for around 2 hours.

@gregx5096 Electronic office consumed more CPU mostly in polling between keypresses, so as to give a more typewriter feel to the user, unlike engineering where you submit a batch job, which does use 100% of the CPU time, but only for a small slice of the overall time, and then releases the CPU. Contrast that to the electronic office, which needs hundreds of context switches a second to process any input, and generate output, so a hundred times a second the single CPU has to context switch, allocate the time in context switch to a user account, clear the memory by writing to disk storage, and then bring in the stored state of the electronic office user, write to main memory, restore all the CPU pointers, and then jump to the next instruction it was to execute before the scheduler triggered the task switch interrupt.
Thus 100 times a second perhaps 1 millisecond of task swapping, for a user time of perhaps another millisecond to process the character typed in and update the screen, then another millisecond of swapping back to the task scheduler to run the next multiuser job. Nearly a third of user time spent in this one application, while the compute job is a single job, that is likely flagged as low priority, so is run during the night, when the multi user system is not running any real time jobs needing that level of time resolution, so can run it for 10 seconds at a time, switch back, and see there is nothing to run, and give it another 10 seconds of run time till complete. Difference is multitasking with high resolution, versus big chunks of time, as likely the overnight jobs are all large data jobs, but they can all run at any time, no need for precise3 scheduling.

@silverwolf6866 They took his money though, he had a rental agreement with them as they have accepted money for him staying there. Either they return all the money, plus interest, and pay for all damaged, or they get to get told by a judge they have to do it, and treble the amount, for the wrongful eviction. The 2 cases are in no way connected, they would have needed to first of all tell him in writing they were evicting, and also serve court papers on him as well to contest this. They admitted they had not done this, by saying they went to the wrong unit in the first place. Pretty much any case they have they already had lost by tossing the stuff in the garbage, not placing in storage, with the first month paid up, added to the fee for eviction.

Another thing is that avionics grade PTFE wire is typically a foamed structure to reduce mass, so there would have been a large surface area available, but in a small volume.
As Phil is in the EU there is no problems for him to look on Ebay for any cheap aircraft parts on auction, both from US origin, UK origin, French origin and ex Soviet era hardware, which almost always has PTFE wire involved in the construction. that will give a nice cross section of wire types and sizes, and of various ages and manufacture, to do a quick test. As a wire it is the correct form factor, and is not a pure PTFE, as typically the insulation used there has some filler or the other added to it to get it to extrude nicely onto the wire, which also has a nice silver plate on it to prevent any chemical reactions between the copper wire and the PTFE with time, contamination with chemicals and heat. The units are cheap in Euro prices, and shipping is very cheap as well. He will also get a good set of samples of the grades of aluminium alloys and stainless steels used in manufacture consistent with the era, for other tests.

Friend made some dried meat, and used a little too much salt in the mix, with the result coming out very salty. As he had rather a lot, he sold it to the one local bar, who loved it, giving it out as bar snacks. Sales of beer basically doubled while it lasted, and they then went to a local butcher, to place an order to make it for them always.
The dried fish locally is a Bokkom, a dried sardine like fish that is almost half salt by mass, and which will keep for years with no refrigeration, just a cool dry space.

Thing is that there is an oil level sensor there at the bottom of the pan. Measures oil level before the starter is engaged to start it on the first cycle of starting, then displays on the display oil level. With stop start the sensor only operates during initial start, disabled if the start is too fast. However it does not work well in operating engine, due to the oil splashing and foaming, or if there is glitter in there, though it also has oil contamination sensing (check oil for conductivity, conductive oil either is water condensed there, or very carboned up oil) built in.
Likely is the owner ignored the oil level warnings, just got in and thrashed the cold engine, and also likely did not bother doing any servicing, leading to the oil being contaminated, and also being used up in blowby into the inlet. So drove it till the oil pressure warning came on, and the vehicle ECM refused to allow engine starting. Then turned off and saw the low oil warning, so dumped in a full 5 quarts of oil, which was still low, so added another 5 quarts of oil, as again no dipstick, but now oil level warning is off. Then proceeded to drive it, and as the knocking grew worse, figured that they are well under water with the likely cost of replacing the engine ( JLR not going to rebuild a engine doing the macarena at idle for sure), plus likely still owing around half the original purchase price, but now it is valued at scrap metal rate of 2c a kilo as mixed. So decided to instead slam on the anchors on the highway, and be given a love tap from the rear, in the hopes insurance will scrap the vehicle, settle the loan, and they come out owing nothing, and with still good credit score, or at least not any worse credit score. Hope they did not get that payout, and the driver that hit them was in possession of a dashcam, or that a witness got this on dashcam.

@aidanhammans9337 Small doses over a very long time, and a guy who would pass any fitness test with no issues.
Knew one guy who, every year when asked his age, would reply "60", even though he had been doing it for a decade or more. He worked as an assistant for a mechanic, and we listened to his stories about his father coming back from "the Great War" when he was a child. And then about him working when the next war came around. At that time this put him at around 80, but he did not want to go on pension, and as he did not have a birth certificate, or any other paperwork, a common thing, he just kept on doing it.

@heyholetsg0 No typical scale off an aluminium alloy heater. Only issue is that using pure water will cause the heater to corrode fast as well. No real way to get around that, as aluminium id always going to corrode when in contact with water and heat. You would have to make it out of another more inert metal to get better results, but this makes it more expensive to make, on an already expensive unit. That heater block is best regarded as a throw away unit, as it will leak after around 2 years of use, and shorter if used infrequently, or with hard water. Ideally should be made from some better more corrosion resistant alloy, but none are easy to cast, and especially to cast with the ceramic heater element inside it as well.
You do not want to see what the inside of a cheap water cooler looks like after a year, the sludge build up is rather gross, and the fins are normally rotting away.

@GeorgeLittle-ft2yx Residual stress from whatever impact cause those initial cracks. Either the shaft got clobbered, or the one wheel was suddenly bound up with a large rock or ditch, and the shock through the transmission caused the initial cracks, but also left a lot of strain bound up in the bulk of the thin side. Just needed enough heat to stress past the yield point, causing the crack, or one of them spread from the heat input to the point it hit the stressed material, which could have been there from when originally cast. About the only way to have prevented it would have been to put the entire casting into an oven, and taken it up to 800C for 24 hours, then let it cool at a controlled rate of around 20C per hour to room temperature, which would have released most of the stress, and likely shown the casting was badly distorted as well.
Big oven, and also inert argon atmosphere as well. Would suggest as well the new casting is bought along with a new output shaft, as that likely also has some buried cracks in it, which probably will show up, with eddy current testing or gamma inspection. Might be cheaper to buy the entire unit ready built, as that gives a warranty on the part.

Funny enough the military by me was not a fan of powdered egg, they would use it, but the fitters and turners in the mess could royally destroy real eggs to taste equally as bad. Now, the thing they served, that I still detest, is pineapple. 3 months of everything in the mess tasting of pineapple, from the water, to the food, to the coffee, to the bread, to the plates themselves. That, and the boiled eggs from the Skinner Street Combined Mess, which were almost universally inedible.
Even food from the Food Factory at the base I was on was better, unless my neighbour, who worked there, told me to avoid certain meals in a day or so, saying in the most succinct way that it was not the best. Even the frozen, defrosted and warmed up fried eggs on soggy toast were good at times, just not the canned sausage they served with it, especially when it was minced up and blended with other left overs. fish was great, just take the thin pieces of "haddock" mornay, as those would not be glassy inside, but well boiled in the milk. Grab that, and a bowl of camo crispies (no snap, crackle or pop, though they often did swim in the bowl), and swap with my friend, who in no way would eat fish.

@stevekaczynski3793 Was at night, he was actually going to bomb a factory he had been going past before the war, as he lived in Hamburg for a while. Were it not that he was a British Colonial citizen, and was in Liverpool in August 1939, he would have landed up in the Wermacht instead, or have been declared an "undesirable". He escaped from his intended fate of concentration camp thanks to the nurses at the hospital, who got him and his co pilot a complete set of SS uniform and helped him plan the escape. Blanket knotted up and thrown through the window, and they walked out the door late one Friday night, and "borrowed" the Kommandant's Adler, while he was in Berlin at a party.
Drove like the clappers for the Swiss border, and because the car had SS flags and registration none of the patrols and road blocks even had them slow down before they went through.
He was still, till he died, not welcome back in Switzerland, as he had belted a police man there, to prevent being sent back across the border without questions. Broke his nose, spilt ink on his uniform ,so landed up in jail and before a judge to prove he was a POW, as he spoke perfect German and English. They took a week to get confirmation that he was actually "missing in action, presumed dead", and got a detailed desription from the squadron CO as to distinguishing features, including his tatoo's.
He was very thankful for the Austrian doctors and nurses who put him back together, more broken bones than intact.
He did visit the hospital in the 1980's (now a hotel) and saw the room he had been in, and regaled the staff about how he had last been there.

Divide by 2 works because there is not enough time to process the LED drive in the time available. So halving the number of times, but still running in sync, will give enough time to output the data and still be above 30FPS.
A thing to try is to have a loop in main running all the time, that simply times the revolution time , counting up the number of interrupts to say 254, and also using a hardware timer to get a clock, that is the number of clock cycles (probably will need a prescaler so that you have a counter with lsb being a few microseconds) taken to run, and then that adjusts the count timer to the new value per revolution.
Now you no longer have to use interrupt from the fan, instead you use another counter that is counting down, and giving a software interrupt that runs the LED flash. This counter gets updated every 254 counts of the main timing loop, to be a time that will give the right number of cycles as blades per revolution. Should then run that code and still not exceed the time between interrupts. With a 9 bladed loop probably can get away with having it run 3 times per revolution as well, leaving more time to have that ADC routine run to read the pot, convert into a PWM value between 64 and 256, and set a PWM for the fan speed control as well. Going to be tricky, now we need at least 3 separate 16 bit hardware counters, but there should be enough in the ESP32 to handle it, though pin assignment will be tricky as some may not be easy to route, and you might need to actually have one or two actually go out and in again, but should be workable, as after all you do have a very fast core there.
Not easy on a 8088, but doable, and there you can always add in extra counters till you run out of IO space, but you got entire message displays that ran with software running the multiplexing, on a 4.77MHz part, and they did not flicker except during scrolling, running low on memory because they only had a whole 2k of memory in there, plus another 2k of battery backed Dallas SRAM for the actual messages, which had 32 bytes for the RTC as well. Plus a thermometer that pretty much always showed that the CPU and board were getting well cooked, as the sensor was right next to the linear regulators.

No, dispute the entire transaction, then get the new card. Let them then prove you had the vehicle that period. Tip when returning a rental car is to video a walk around on return, along with pictures front, rear and sides, plus on roof, making sure to have registration plate and also VIN in one or more of the pictures, then picture of the keys, then picture of the return box if dropping off, or picture of the receipt. that way you have evidence, and if possible include in the picture the daily paper, or other such thing, to have proof of date other than picture metadata. Email pictures to yourself immediately as well, as email is harder, especially Apple or Google, to disprove or spoof.

Yes there are standard recording papers for these, with a pressure sensitive surface the pens move on to leave a mark. Kienzle is the most common type, you should be able to get packs of them on eBay for cheap, along with the tacho mechanisms themselves.
There are more modern ones, which in addition record things like engine temperature, oil pressure and brake application, so that you can reconstruct incidents after the fact. I did get a few broken ones to take apart when I was young, as my father was in control of a fleet of around 300 trucks delivering stuff, so had stacks of these cards around.
The more common types are used for process control, you need to look out for pneumatic controllers, where they use air pressure and almost no moving parts to control valves, using air jets blowing on steel plates to control massive industrial processes.

There has been a recent case about this, with a few hundred vehicles recalled, because the assembler that did a major part improperly fixed a robotic welding cell, and did not do the required recalibration of the cell, so it was not doing all the welds correctly, instead a good number being done with no clamp pressure, so they were not made. Do not remember which manufacturer, but this is the same.
Would be interesting to look at the nearby VIN numbers for this model, to get vehicles assembled on the same day, and see if any of the owners have had to have frame repairs, which would, with 2 examples, force a recall for the entire week production to inspect, and if needs be, replace the frame as well. Wonder if there have been any involved in an accident as well due to frame failure, which would mean an even bigger issue arising, or if they had any other complaints. Will bet the manufacturer is absolutely looking at any of the vehicles in that week range that are in for any service at dealers, and checking they have all the frame welds done.

Manufacturer, as they want the entire vehicle to last just past the warranty period, and then you scrap it and buy a new vehicle from them. Dealership wants the vehicle to last as long as possible, as they make the money from servicing, not from new vehicle sales. Many examples of vehicles that suffer from severe engine wear that shows up just after warranty period expires, when you use the manufacturers intervals. More regular changes are not environmentally unfriendly, as oil is a very easy to recycle material, and there are generally a lot of ways to do so. ROSE foundation is quite willing to do it for you, and the oil is either refined for use again, or used in industrial processes, so overall it is not dumped.

Even to support a single aircraft you have a large ground support crew, from messing, to needing security there, to needing a whole slew of ground support equipment that has to go there. Plus you need a runway first and foremost, which is not easy to airlift. 6 aircraft needed at least 4 transport aircraft for crews and tools, and another 10 vehicle convoy with heavy trucks, that took the stuff that does not fit, and then another 2 dozen general purpose trucks, and 100 warm bodies, rented from the Army, to provide the grunt work to assemble tents, put up the camouflage revetments for the aircraft, and provide security for the perimeter. Then also you needed water tankers, a few fuel tankers, and as well generators for power, to run mess and power the ground equipment, plus an important one being the honeysucker to keep the smell down, and some form of garbage disposal as well.

Yes, and they will be paying for 5 vehicles damaged or totalled in the accident, then also have to pay for their own vehicle damage, because the insurance will refuse to pay any of the claims out, citing reckless disregard and criminal negligence on the part of the driver. Then they will be stuck, even if insurance does pay out, on having to pay back the entire claim, and this type of debt will never prescribe, so they will now be without a car, high insurance rates, and no chance of vehicle loans other than at the pay here drive here places.

You can see a skirt on the base, so likely it was lowered onto the stand and sat on the skirt. Then they likely used multiple clamps to hold the skirt to the stand. Most likely is that one or more of the clamps either were not tight, or the bolts had been machined undersize, leaving not enough thread engagement, or only a part of the thread was engaged. Then the thrust snapped those, and the others that held tore the skirt loose, which accounts for the damage, as that skirt likely also damaged the engine bells as they rose up past the stand centre, and either bent them or fractured them.
Bent ones got hot spots that later on failed, and the cracked ones were losing lots of cooling fuel till the uncooled areas melted away, and caused that engine to shut down because controller saw dropping thrust. Then the remaining engines were slammed to 110% to compensate, and this extra stress meant that one of the dented ones split open, and the parts blown off into the plenum damaged piping and such on others, and also likely destroyed the guidance controls, as it did not recover. Thus the big black cloud of burning fuel and hydraulic fluid, and bits of engine rich exhaust.
Controller saw thrust was dropping on those engines, or pressures were dropping and flow rates were running wild, and shut off them, trying to correct attitude with the others by throttling them back and trying to correct with steering the remaining engines, and then it went horizontal. It probably detected a launch abort, and attempted to blow the destruct charges. Of course, seeing as this is a test firing, those likely were not fitted, just had the test bypass units in place, to pass the regular self test cycle.

Banks used to store all returned cheques, along with copies of statements, as microfilm images, processed by some central facilities as they were processed. This film was then stored, undeveloped, for the required retention time, then recycled for the silver content. As the banks rarely had to retrieve any information off any roll, they left them in the canisters undeveloped, as the cost of developing them was pretty expensive, and thy relied on the fact that most of the time a query would come in while they still had a paper copy or the original around to use. If there was a need for one of the images they would then develop the film, and hope that the scan had been successful, or at least came out readable.
IIRC less than 1% would ever need the processing and development, saving a lot of money on film processing, plus at the end of the retention process the film was more valuable as scrap silver, as it still had all the original active halide salt in it. Then the film would go and get stripped of emulsion, and the silver recovered from this residue.

My father left a Lancaster sans parachute, as it, along with the plane, were well ablaze. He woke up in an Austrian hospital 6 weeks later, after being found, apparently dead, in a snow bank under a pine tree. Morgue doctor listened, found a heartbeat, so he got a hospital bed. Back burnt all over, broken neck, broken jaw, broken collarbones, broken ribs, broken arms and broken legs, but he recovered well.
He found out from the nurses that, once well, he was to be transferred to a concentration camp, Auschwitz, so decided, with a little help from the nurses, to escape, along with another British POW in the hospital as well. Borrowed an Adler staff car, and they went for the Swiss border a few kilometres away.

@LeviHildebrandYT Basically you are forever owing at least double the amount, even immediately, and they make the business model the finance charges added each month, along with the charges being applied to the purchase, but split over each payment, so it initially looks less. they bank on the fees being paid for missing, as that is the business model, make sure you will incur at least one fee every two or three payment periods, because you might only be paid month end, and they conveniently say each month is 30 days.
Makes the Mafiosi at the cash loan place, that guy with the wall of fingernails as "reminders", your friendly local loan shark, look like a business owner with ethics and honesty.

Yes steel will last forever (corrosion excluded) in cyclic loading that does not reach the plastic limit, but aluminium, unless you use some rather expensive alloying metals in the mix, most of which are pretty toxic in themselves, like beryllium, the aluminium will start to show fatigue cracking after only a few thousand cycles of even moderate strain. then these cracks will propagate and result in failure. unless you keep the cycle load so small that it is well under plastic limit, you will have to replace it after a certain number of cycles. Which is why a lot of aircraft are scrapped after 20 years of service, as the cost to replace all those fatigued panels and stringers comes up to close to the cost of a new aircraft, which will be both more fuel efficient, and will also have a better passenger capacity, and lower running costs. Just the cost of checking all the wing spars for cracking, the most critical part, are so expensive that when this is due most are going to be scrapped instead, as the parts are worth more as fix parts than as an airframe.

Yes the title now is often printed on bond paper. Seen an old 1890's era title, hand written, in copperplate, with the paper being watermarked OHMS, and with both embossed seals and wax seals with ribbons on it, along with revenue stamps, also stamped and embossed, indicating the appropriate duties had been paid. Sadly went to the title office, where they had to shred it to cancel the title, and issue the new one with a plain paper, simply stamped and rubber signature, of the issuing office.

I would hazard that the case against them is so tight that this is the least expensive outcome, as they likely were told by their legal rep that going to court would not only have this as a minimum cost, but also would lead to criminal charges, and possibly a long sentence in federal prison. Selling up and all proceeds going as fine is what they did to avoid 20 years for something, probably for more than labour violations, and probably more for lifelong disability payouts to some person who had a hand sliced to uselessness by their operations, and that person was a minor at the time, and now is on disability pension. Then also likely tax evasion, and thus the prohibition on owning a franchise forever, likely the sealed part prohibits owning any franchise, or owning any store at all, and also prohibits them from having any directorships or control of any sort of company or closed corporation.
Want to take a guess the next case against them will be an internal IRS court case, which is going to strip them of pretty much all except clothes on their back, a car, lowest value one they have, and a suitcase of clothes to wear while sleeping in said car.

Ford Kuga, where they use the same electric door latches and locks, where there have been a few cases of the driver burning to death in the vehicle, because they had defective hydraulic steering hoses, and the resultant fires in the engine compartment burned the electric wiring from the BCM, resulting in a failure of the CAN bus, and thus being unable to unlock the doors from the inside, or the outside, and the lock mechanism when electrically closed disables the existing unlock button, meaning you burn to death. the emergency release is not easily accessible from the seat when sitting in it as well, so you are effectively trapped and going to be cooked alive.

Thing is that they literally have the glue bond inside out, as the ring should have had an internal structure as well, to transfer the compression force from the carbon fibre to the inner titanium ring via the epoxy, not put a tensile pull on the epoxy join. That would lead to the carbon fibre delaminating with pressure cycles, and failing. They constructed that join surface as if the join was for a pipe with pressure inside, where the pressure will hold the epoxy onto the cap, not the other way round. Pipe shrank under pressure, and eventually some microscopic section of the join, likely with an embedded air bubble in it that had been compressed to have a sharp edge, caused a stress that started to propagate through the bulk resin, because there is no stress relief in the resin bond, and this then eventually grew to the outside, where water was able to fill the crack. Now the water is applying pressure to a section that can flex, and grows the crack into the joint further, aided by the tension in the epoxy join, and this then rapidly, basically the speed of sound in the epoxy as the growth speed, grew to open the joint to the inside.
That joint should have had an inner and outer lip, and have been filled with epoxy with a slow cure time, and then have the shell pressed down into it, also with a coat of the epoxy on the surfaces, and then pressed together, with a few vent holes for the excess resin to flow out in the titanium, that later on would have a cap bolted and bonded to it. Or a thicker section that you put a setscrew in to fill the hole, while the resin is still not cured, after it has bottomed out, then left and heated to cure fully before removing the pressure.
That join section should have been at least 3 times thicker, and longer, with a taper on the inside to allow a flexible sealer to be there, to allow the join to flex with pressure, not a solid non flex epoxy only. you want to not have stress risers, and a solid join with the different materials will have that stress riser. This hull was likely only going to last 3 cycles before you would have to replace it, they should have done testing, using a deep water area, and a cable and cage, to measure the number of cycles to failure first, not used the passengers as alpha testers.

By me cooling is the much more important thing, but as a heat pump is pretty much the same price as a cooling only unit I went with the heat pump, as in the smaller sizes the cooling only is actually rare and expensive. 1 extra wire in the cable set is all you have, to control the valve, and thus easy to do. Actually used it for a whole 2 days this last winter, because it was unseasonably cold for the sub tropics, dropping below 10C on a day or two in the morning, so the warmth was a nice thing to have for an hour or so, before it was turned off again, and natural air was better. Summer time it was needed, keeping the inside cool and dry, as it was hot and humid outside, so well worth it. $350 for the unit was well worth it.

So familiar that cockpit layout, though there are definite variations between operators, and you get a whole host of things that are upgraded differently, but a lot of those instruments and displays are common between them, and the later versions of the Mirage as well. That NAV computer is also I would think, if original equipment, all electromechanical, using a whole collection of electromechanical boxes in the nose and belly to do the calculations, using the inputs from the centrally mounted Air data computer, behind the pilot and under a fuel tank. not a fun thing to change out, so you would find every other part of the system changed out first to troubleshoot a failure on the ATE systems.
Moving map as well a blend of electronic systems and mechanical intricate parts, to be able to both have a film cassette with the desired areas of interest on them ,in multiple resolutions, along with being able to move the entire cassette in both X and Y directions in the particular frame, along with rotating the entire film cassette mechanism to allow the pilot to have a moving map display that faithfully represented the view outside. I helped repair a lot of those things, with the 12V 250W halogen bulb that delighted in burning out, and killing the driver circuit, so the pilot would select the spare bulb and not have a display other than a half second flash. We were using a lot of the old nav computer arrays as spare parts, the computer having been replaced with an all electronic inertial guidance system, which was both smaller, more reliable, but definitely equally power hungry. A lot of common synchro units in all the mechanical systems, and a whole host of the parts were FRU's and plugged in.
That Cyrano RADAR is not at all bad, but by modern standards very dated, but still for the time it was designed, well capable for the limitations of the envelope. Well worth the modern upgrades though, you got so much more out, like a CRT display.

A lot of very bespoke computer designs were around before the microprocessor came along and guided them into a few very rigid areas. Especially those that were made from discrete logic, and where the designers went and made it with instructions they needed, and little more, and where your software and hardware were very tightly bound. Designed for the purpose, and then made to be as compact as possible, with, in that era, as few transistors as possible, because they were both very expensive, and also not as reliable as diodes. So you had a lot of diode logic, with transistors scattered around where absolutely needed, to act as inverters and regenerate the logic levels.
Many of those designs were translated into early IC based systems, and they often used EPROM to do complex functions, like a lot of glue logic, and also to store tables used in math, so as to simplify multiplication, giving you the ability to have 2 5 bit numbers be multiplied together, to give an 8 bit output, in a single clock cycle. Used a 2708 1k EPROM, holding the decimal number table, and allowing you to do multiplication in a few cycles through the table per digit.

@knightmarex13 You remove the slide, fold it up into a very large box as per instructions, and send it to the manufacturer to have it serviced. Then you take a spare one from stores, complete with certification, and install it, along with all the surrounds that come with the kit. One day job if spares are there.
Manufacturer takes the slide and examines it, tests it, cleans, does any repairs, then deflates it, fills it with preservative powder again, before folding up into the package, then replaces the initiators and the triggering mechanisms, and puts it back into stores as a refurbished one. Will take around a week all in all to do this, including all the checking and signing off by the various inspectors.

Yes, looks like it was a prototype for a documentation box, made to fit into the cockpit and to hold the flight manuals and all the paperwork for the flights for the day. From the interior you can see it was hand riveted, using a pneumatic tool on the outside and the hand buck inside, and all of the material was standard aircraft use. Those corners are normally made by taking a sheet and running it through a shear with a depth stop, to make the long strips, and then that long strip goes to a bending brake to be made into right angles. For the corners most aircraft shops have a right angle nibbler that will punch those out automatically, and for the rivet lines you also have a set of jigs to allow that correct hole spacing to be done easily.
You can see it was made 1960's 1970's, because later on the thing to show off was TIG welding those corners to have a smooth bead, either a single smooth bead with no porosity, or a smooth stack of coins all even as bead, both sides. this was an internal prototype, made to show form and fit, and likely was later on used to generate a set of plans for a production box, if the design was not discarded, like so many were.

In the military there was an accident involving a military vehicle, and a tow truck took the vehicle, and were holding it demanding a massive fee. Friend, who was a motor mechanic on base, went and got that bill, and a lot of attitude from the tow operator and staff. So he went back, told his boss, who smiled, and picked up the phone. He went back with 2 APC's, 15 very bored fully kitted out reaction squad members, and the military tow truck. they went in all ready for bear, and held the entire crew on the floor at gunpoint, while the vehicle was hooked up to the tow truck, and driven away, and then the reaction force left, telling the tow operator that the next time he tried to tow a military vehicle withou a written authorisation, they would not come in politely, but would come in as if it was a hostile operation, starting with tear gas first and then coming in hot. Plus also that tow company was blacklisted on the government company database, so they would never get even a government tow job, or even a move vehicle out of the way job.

@DarthVader1977 He might not have had a job at the time, or the child support was more than he was earning. So now you have a person with no job, or a low paid one, and you now want to either prevent him getting a job, or getting a second job. Way to help him, by preventing from legally earning money, kicking him when he is down.
Until you look at why all are assumptions, so easy in the USA to be fired because you had to go to court, and your boss is an undiagnosed sociopath, who gets off on bullying underlings, so he works at jobs where he can get away with it, and the company does not blink at a massive staff turnover, as this saves money on paying more than minimum wages for what they class as unskilled work.

Had the same come up regarding a rental agreement, and I phoned the lawyer who said he witnessed it if he was willing to say so in court, and that I had multiple handwritten examples of the signature purported to be on there as the owner, and that he might want to reconsider if he wants to present that into court. He figured out that disbarment was not a good idea for presenting forged documents to a judge. Signatures wildly different, and also the handwriting, even to a lay person. the tenants got an eviction notice, after the unit was sold to defray outstanding levies and damage. Lawyer got the money, and I told all those who had outstanding damage to submit claims to him. All paid, and the rest went as fees and tracing monies, as the owner was MIA, dodging others. Took 2 years for the money to vanish like water into sand.

One reason they have not replaced them with LED is that they are old controllers, and thus also have old conflict monitors, which are there to monitor all the lights, so that no fault can cause the light to show go on cross directions at all, any fault that might do that will cause the conflict monitor to disconnect the controller and go to a flashing red all round as a safe indication of it being a 4 way stop. Old controllers are there till they run out of spare parts or the pile of others removed from service, and will only be replaced with new controllers when the old ones are out of stock completely.
Newer controllers can have LED drive as standard, but are difficult to retrofit to the old controller, as they probably are from the 1980's, where the controller also had current sensing that allowed remote monitoring of lamp failure, allowing non reported lamp failures to be repaired without having to have a monthly check on all lamps by a crew, and also this showed the relays were working correctly, giving a backup for the conflict monitor.
Had this happen here, where the last 2 Automotor mechanical controllers were replaced eventually with Siemens controllers, hope the old controllers were kept for the transport museum though. On some of the controllers they had to add "cheater" lamps in the controller case to provide enough load to make the controller and conflict monitor happy with LED loads, but as almost all the controllers also had lamp soft start built in the lamp life of 8k hours was more like 20k hours as they were either kept slightly powered by a low current or had soft start resistors to keep inrush current low.
If the municipality wanted to save money they could also just get by replacing the red and green lights with LED, leaving the orange as incandescent, as the 5 second on time per cycle is really low power overall, but red and green are the major power draw. Plus the burst of heat in amber helps to keep the snow off, though here, where the last time snow fell was millions of years ago, extra heat is not exactly needed. Have seen LED clusters showing 2 colours on the same pole, then a 30 second flash as conflict tripped and made it all flash red, before cycling back again to normal for the rest of the timing cycle, and then rinse and repeat.

The highest power user in modern processors is just the distribution of various clock signals around the die, with more than half of the active power being used to drive clock signals that are used to latch the assorted logic systems. that is why there is so much research in cutting clock supply to any unused parts, even if only for a single clock cycle, not running that clock for say half of the individual ALU of a core, which for a cycle or two is not actively doing work, means a big power saving. Even the bus latches that are tri stated and not actively driving an internal bus will benefit from not having the internal latching clock, almost always there to latch the internal state before delivering it out, being turned off as well. That along with non clocked logic that relies on propagation delays to provide a smooth execution path, are all things done to reduce power use.
If you want crazy look at how small cheap chips generate their internal clocks, using an evolved set of logic that, due to quantum interactions between gates supposedly not connected, makes for a clock system that both self starts, does not use large areas of silicon to make RC systems, the old approach, but instead becomes a VLSI macroblock of literal magic that you drop in from the EDA tool, designed for that exact process, that will magically spit out a clock with a reasonably constant frequency, and which is all within 5% on all chips, good enough to use to run say USB devices with no need for the 11MHz crystal normally used to allow the communications to take place, using the internal clock to start up, and then having another clock derived from the signalling to talk back.

I would also surmise that, despite it saying 100-120VAC on the outside, the board itself has 450VDC capacitors on the input of the power supply, and the controller is capable of handling input from 80VAC to 265VAC with no problems. As these are sold world wide, making 2 different voltage models is very poor manufacturing wise, much better to design it to be universal, and get economy of scale on the production run of the power supply. then you can make up the complete units and if desired place the outside sticker to localise for the country it will be used in.
That they used no thermal compound, or even a silpad, means they designed this to have a shorter life than possible, as the pad would double the operational lifetime of the LED chips by improving heat transfer, and would enhance the operating range at the high end considerably. Those were used, judging by the yellowed look of the led chip cases, they should normally be bright white when new, but fade with the intense light of the dies with time.
Here most of them use multiple strings of 5mm LED's and run them off a 12V SMPS supply, giving redundancy as the strings fail by having so many of them.

But antimony is a very important metal, as it forms part of many other alloys, and is a very sought after metal, that are worth money, not as much as gold, but still worth mining. It makes the modern car lead acid battery possible, as an alloy in the lead, along with calcium, it makes the plate structure harder, and thus allows a thicker layer of lead oxide to be pasted on, and also improves the conductivity of the lead, meaning you need less metal in an inactive form to conduct current in the plate structure.

Well, Bentley and Rolls Royce were the major manufacturer of aircraft engines till the turbine division was split off. Thus the engine designers in this era brought through the aircraft design philosophy, that fasteners should really stay fastened till service was due. Plus, as the price of the vehicle is rather high, the thought was that owners would be able to afford the service cost, even if half the cost in the service was labour hours. Rolls and Bentleywere not shy with pricing, but they also would make sure in those days that the stuff would not break, even if you abused it. Big engine, old technology, wet liners, that cursed hydraulic system (just wait to see the trans, it drives the rear brakes off the output shaft, so they come off when you stop) and the electrical system that could have "interesting" faults in it.

They have a steel multipart mould that they blow polystyrene foam into to make the pattern for the block. This pattern is a complete head, fully detailed, so that when sand filled you simply take it and pour in the liquid aluminium and it burns the styrene away so you do not lose fine detail. That allows you to make thousands of patterns and not have any major wear on the master mould, and also the fine detail that you otherwise could not make in a pattern, like straight sides and undercuts, along with complex internal shapes, is easy, as the styrene parts are easy to work with, rigid and detailed.
Might be a half dozen styrene parts finally into the sand, but one assembly, and there is no danger of crumbling blocking parts. Just glue them together with a drop of wood glue on the bonds, and fill with your casting sand, and cure the sand before pouring. Instead of lost wax this is a lost mandrel process, and the detail is fine enough that the actual polystyrene beads detail is impressed into the casting. You can get a really thin wall casting out of this, yet not have many failures due to blow through or incomplete pouring.

Main heat source is the massively increased number of passengers, each of which is an equivalent to a 150W heater, plus each releases both CO2 and water vapour, so you need to actively remove those with the heat. the trains themselves are not really a big heat source, regenerative braking recovering a lot of energy, and brakes only to do the final stop, and the trains act like very efficient pumps, moving air in the tunnels to the stations. you have ot cool the air going in, or move massive volumes at each station, which is a problem with old stations with small ventilation ducts, in that to move air in you need lots of pressure, or bore out the ducts in the ground to be a lot larger, and have the passenger entrances with a high air flow as exhaust, along with mid tunnel sections that also exhaust large volumes of air to ventilate the tunnel and remove air from platforms. A big issue with there being no space to put this added equipment and needing to find space above ground to do the air inlet and outlets as well. Quite a few false buildings above underground routes that look like a surrounding building, but which are there to hide the massive fans and holes for underground rail ventilation instead.

@webcomment8895 Low speed impact, vehicle was stopped so the airbags did not go off. Airbags are not made by Tesla, they contract the entire airbag and controller out to a specialist supplier, like Bosch, so use the standard deployment impact forces. You had the impact cause injury, but the primary restraint system (seatbelt) did prevent him getting serious injury, and the passive safety systems (crumple zones) absorbed the majority of the impact as well. If the airbags went off for every similar energy event, you would find them going off on things like hitting a kerb, braking hard, hitting a speed bump over the listed speed, or even a shopping trolley hitting the front.
Would you like to have your airbags deploy like that old meme of the car honking at an old lady crossing slowly, and then she hit the front of the vehicle with her handbag, triggering the airbags?

I heard of one pilot who went through a cloud, felt a bump and all the gauges barberpoled. Comes out of the cloud a half second later, and ejected. After separation he saw the front of the plane falling down into the valley. The bump was the plane striking a mountain top, just behind the cockpit, and shearing off there.. Those tiny navigation errors do add up, especially in the days when GPS was still a US top secret thing, and all navigation was done with inertial systems, Decca and LORAN, and with following a map. AFAIK the remains are still there up on top of that peak, well burnt. Just 10 feet higher and he would never have known, and 10 feet lower exactly the same.

One major advantage of the single speed compressor is reliability, the inverter is a simpler 3 phase motor yes, but unfortunately it has a very big drawback in the inverter driving it is in general built down to a price point. 3 phase motor in industry is the most reliable thing around, when it comes to turning electricity into motion, and will last essentially decades with zero maintenance. Sadly the inverter that drives it is not, and is the thing most likely to fail, after the internal fans used to blow air inside the case, so that the coils and defrost mechanism can be hidden behind a cover so the buyer does not get confused by al this technology stuff.
I see all manufacturers loudly proclaim the compressor itself has a 10 year or more warranty on it, in large letters, but in the much smaller print at the back of the manual, there in the 1pt flyspec font they use for all the writing in the "warranty" section, you find this covers only the compressor motor and the pump attached to it, in the hermetic housing. Not the piping, not the case, not the controls or the expensive ( single most expensive part in the unit, as the manufacturers will only sell this as a set with a brand new compressor as service spare) inverter board. Compressor only, and not if it rusts through from the outside, because it condensed water in the off time, and it pooled at the bottom of the case and rusted off the mounting ears.
Changed way too many AC compressors under warranty for failing, and those had a 5 year warranty, and I was, due to painting the case inside and outside every year, and cleaning the coils as they corroded, plus good record keeping, able to actually get those warranty claims held up. The supplier did not care, I was buying shedloads of other spare parts in the interim, along with new units on a regular basis. Indoor compressor run in a calm environment I would never change it, but these were all outside in the sun and rain. Fridges and freezers they were never worth repairing once the gas circuit needed anything, at least for the last 20 years, where as before you had separate coils inside and out, that are repairable, even if they are steel or aluminium.

Major driver was cost of licence. Sony had a per machine royalty, while JVC was a lot less worried, with both much lower costs and a lot less actual chasing up, so that manufacturers would look up the cost of making a machine design, and choose the cheaper option and make VHS. As well the actual mechanics were easier to make, quite a few clone manufacturers could do the entire machine easily enough, but only found the head drum assembly too difficult, so resorted to buying them as spare parts for larger brands. Did drive Matsushita crazy for a while IIRC, with the number of head drums they were selling to the repair market, till they finally found out why, and probably started offering them as a ready to use part instead, getting in an extra profit for essentially already paid for production capacity. Then the cloners got to the point they could actually make the whole machine in house.
Sony however wanted tight control, which both costs money, and also stifles innovation and changes to the mechanism, while VHS found a solution to big drums in the VHS-C with the smaller drum, faster rotation and extra heads with switching, but which left a standard azimuth track on the tape, which also was used in a few full size smaller units as well. Assorted mechanism types were to get it either smaller, lighter, cheaper, or more compact for some application. Last VHS decks I saw consumer side were essentially one single plastic injection mould of all the parts, integrated with a single sheet metal stamping, to make the deck, complete with all of the tape mounts and eject mechanisms.

Hard to have water perfect for the fish, with low nitrate and nitrite levels, and still have enough nitrate for plany growth. The tablets just make a gradient for the plant, while the filter is busy breaking it down and removing it. What you want is Eichhornia crassipes, the common water hyacinth, which will absolutely grow there, and you will be forever ripping out mats of it to place in sealed bags, and freeze for a week, before dumping in the trash, because it will literally grow on any water surface that is slow moving. The fish will also use it for cover, and they will eat it, possibly even faster than it will be able to grow, but not too likely in a warm climate. Lovely purple flowers too, and it has built in floats as well. Should be easy to find at a pet store, or just look for the distinctive floating vegetation at a local lake. If grabbing wild take the plant, and use some pottasium permanganate solution to soak it for an hour or three, covering the entire plant in it, to kill off any nasty bugs that might hitch a ride with it. then leave in a bucket for a week to recover and start to grow, followed by another soak and week in fresh pond water. Big koi love them even more than cabbage.

Plain dome is front, port is under the sand. Back section still has the glue holding. Front was blown right off, so likely the failure point was that rear dome joint, as the imploding section would not have had much energy, but by the time the piston of water had reached the front it had enough energy to blow the front dome off, blow out the viewport, and shear off all the mounting bolts, as they are not really there for any structural use, merely to hold the front seal in position till water pressure forces it into seal properly. The rear intact says that was the top that failed, probably the back third of the carbon fibre, based on all of it being wadded up into the rear dome, and not enough energy to blow the dome off completely, but tearing the fibre mat and folding it into the rear.
will be interesting to see the front dome pictures, showing how it delaminated, and yes very likely the entire epoxy ring did pop off, but the poor adhesion probably was not too much of a factor here, as even if it did fail, the force would not have popped the entire dome clean off.

When you are running stretch bolts you have them, and also the same for any fastener designated as use once as well. you are getting it out of the elastic region and slightly into plastic deformation, so that the tension in the bolt is higher than any force between the surfaces. Now to get that you need to start at a known tightness, and then stretch it so much, thus the degrees from a known torque that has them firm against the gasket. The second round is so that you allow the tension to be relieved, and then stretch it even further, getting closer to the yield point of the material, but leaving enough margin so that you do not have any failing in use. Use once so that you will not use deformed bolts, though you can measure them in most cases, and if they are less than a specified amount they have not stressed too far, though if there is a region that is waisted narrower than the standard diameter that bolt is close to failure, and needs to be replaced instead.

I got a payment from my metro. Clobbered a pothole left by them fixing a water pipe, filled with water in the rain. Put in the claim for a new tyre, plus installation and balance, along with the filled in claim form, and with the pothole marked on a google street view image ( showed the valve they had dug up to fix the leak), and after 4 months got the settlement of 70% of the cost, which was pretty good considering the tyre damaged had around 50% of life left.
Of course now they have so many pothole claims that it is easier to find streets with potholes than to find 50m without one. Then you get the stupid things like cities attempting to sue people for fixing potholed outside their house, because that is supposed to be a municipal job, but they have not fixed for a decade. That one the city is losing badly, both in court and in public opinion, because they are getting now thousands of pothole complaints daily, and also getting sued left right and centre for failing to fix them as well.

@AaronSmart.online Ceiling fans are a definite must in the tropics and sub tropics ( so most of the EU, aside from those places around the Med, are out), and all of them I have met start off as high, medium and low. mostly because they tend to have bearing issues with time, and the bearings ( or bushings, depending on how old the fan is and who made it) will tend to become sticky with time, but so long as the fan is able to start turning they will run. Thus you start on high, to get the best chance of the bearing getting it's hydrodynamic film built up and thus reducing wear, as a slow moving bearing or bushing is going to have very high loss,, simply because of metal on metal contact.
In general the fans only start to give issues when older, and often I cure it with a new capacitor, as most ceiling fans I meet are not shaded pole types, but split phase. Bearings getting stiff it is possible to lubricate them, but often the housings are pressed together, making it hard to get to them for a good repair, and the modern trend is to use that horrid CCA wire as well.
The ones on my ceilings are around 20 years old, and still work well. The smaller fans almost all are split capacitor, though the old GE fan is rather odd, in that it achieved phase rotation by having variable reluctance in the pole pieces, using thinner sections of the poles to provide a saturating magnetic field. As the field saturates it appears to shift, allowing the fan to start as the field is moving, and not just varying with time, just like the shaded pole does, but without the need for the copper shorting coils to bring about the field saturation in the motor. higher starting torque simply because there is no circulating current in the pole pieces, so more energy available to induce a rotor current, plus the rotor is skewed, so there is a bias as to start direction built in.
Yes 230VAC country, currently ( amazingly) 233.2 VAC , though it can go up to 247VAC at times, but after they replaced the 90 year old transformer across the park (it started leaking from the base valve, so went for repair instead of just a new valve) the newer one ( still around 30 years old, they are refurbished because of the cost of new ones) is set more closely to 230VAC instead of the old one being 240VAC. I lived in a place with the original 130 year old 250VAC supplies, and there cooking was great, but appliance and lamp life was not, though your lamps were extra bright. That will never change, as they would have to replace over 50 transformers at once, so keep the taps on the low side instead to meet spec for high voltage.

Well, if there are enough firms are involved, how will the owner be able to get a lawyer, seeing as none of them will be able to represent the owner, without having a conflict, for being one of the people on the opposing side. Plus now promoters will be placed in the difficult position of being forced to repay ticket sales, plus being sued for discrimination, on the grounds of any number of reasons, especially if any of the banned fall in a protected class, and use this class as part of the reason.
City will likely step in very fast, because they after all are the actual owners of the facility, the owner merely having a 99 year lease on it, or paying the city a fee based on some sort of deal. Their lawyers likely are already on those lists as well.

Yes ship power delivery is a lot more complex, and the panels are largely automatic, in that they will automatically assign load priorities, so will, as the load increases, drop off the less critical loads to limit current, and keep the main systems powered. Container power will be a less critical load, propulsion related power is priority, and then lighting, as that has lots of battery backed emergency lights for it, and then cargo and non essential loads. The power trips here were very likely from the generator sets dropping off line for some reason, or one of them dropped off line, at a load that needed them both to provide more than 60% of rated power, and the second one had an overload trip before the emergency generator could come on line, and the load controllers could not drop loads enough to keep main power buses on.

Die without a will and you land up in a long line awaiting a legal representative, out of a pool in the area, who will get to it in good time. Takes at least 6 months after that for Master of the Supreme Court to appoint the lawyer as Executor, and from there only then can they act. Then publish, wait 3 months, publish again, and then wait another 3 months for all creditors and debtors response, and then finally start to wind up the estate. So even with a will it will take at least 2 years to finally wind up, and without all these get drawn out to an extreme, especially with a large estate that falls over the tax threshold, so that IRS has to get involved to verify every part. Even with a will it can take a decade to get it finally closed.

@marksmallman4572 If your new bearing is $1k, and refurbishing gives you half again at a minimum as much life for $300, it is worth it. For very large bearings all will be refurbished at some point, especially as the price goes over $5k, and lead times for new ones are measured in months. Some you have little option, as a new one might be a year or more to order, and you need the machine to run, while a refurbish might only take a week.
For some you just have to do it, as the original manufacturer might no longer make them, which is common in older precision instrumentation, as the bearing races are actually part of the machine, and you simply polish them and put in matched sets of balls. There your refurbishment means you select from a whole series of slightly different diameter balls, to get the right clearances in the machine.

Also your mobile phone absolutely depends on GPS, just to provide an accurate clock that allows for the time slots per device to be as tight as possible, allowing for maximum data throughput, but also to provide an accurate clock that allows the base stations to be able to use QAM256 to get as much data through per signal transition, using the GPS clocks to generate a very precise, as in down to single parts per billion accurate, clocks for the base stations, to do this. No GPS, no clocks, and very much degraded phone service, as the towers need to fall back to a very coarse clock provided by a heated crystal, good enough for one part per million, but now resulting in a much reduced data rate per device.

@TommiHonkonen Even if he did cut deep, Kurtis could still weld it up enough to cut that thread back again, probably even fixing the original damage as well, then cutting to match the original nut if they had one. But now he just has ordered a big chunk of good quality steel, and is going to take 70% off it, in order to release the inner nut hidden in the block. Hopefully one of the new tools is a set of diamond hole saws, to cut out the inner section of 120mm steel, so that he can either save cutting tools, or reuse it on another job as bulk steel rod. After all, if you do not make it into chips, you save a lot of time.

Correct, at 3k the error between the aiming point touching the circle of the sight, and then releasing the load, is a lot less than at 20k trying to both see your aiming point and decide it had crossed the mark. Even modern planes releasing non guided munitions have the same problem, one heck of a lot easier to hit the target when flying low and slow, than up at near max ceiling with all the different air currents moving the munitions willy nilly. Even with modern aids you are going to be hard pressed to get in the vicinity with any sort of precision. Only way round that is to go the B52 method and lay a carpet with multiple aircraft and multiple sorties, and even then actually hitting a specific target is hard.
Attack pilots would go out and definitely make a mark, especially where they have a spotter with a radio saying the target is 1km north of the red smoke. 100% make a chunk of holes 1km north of the smoke, and might actually hit something as well. But more often than not just made the target hot foot it out at high speed back to the border. Good enough in most cases, and better than hitting your own guys. Sucked if you were a cattle herder, you got instant ground beef, and then spent a week rounding up the survivors.

@eliasthienpont6330 Solved by having a dealership per state or two, and send out a tech to you. Then bill you travel based on distance from your dealership, even if the tech lives next door to you. Then bill for travel time, diagnostics, and then the part itself, so a $5 sensor, that you can literally buy at Autozone for the same price, results in a $5000 bill, because the faulty sensor now is replaced, but the computer now has to be told there is a new sensor there, to operate again.

Probably will need around 5 times the delta V to deorbit, though of course that is also something you can do with just using a large ion engine, and a lot of fuel for it, with power being provided by the on board satellite arrays, as you would need minimal power to charge batteries as they only will have to provide orientation and 45 minutes of low draw during the night passes, and will not really need to power much in the environmental system with no people on board, do you can simply shut down and drain a lot of the systems to safe them, then keep the bare minimum like attitude control, computer systems and circulation to even out temperature.
You can close all the airlocks as well, and that will reduce the need further for power. Just your booster bus will need some redundancy power wise and control wise, probably like the shuttle, 5 general purpose computers to run it, and likely some solar panels to augment power, and also a lot of RCS fuel for attitude control. Easy to do if you have 2 of them one each end, and thus taking turns in providing thrust in orbit to raise it, and slowly over say a year getting up to a relatively open orbit. To get past LEO will take about as much ion engine fuel though as what you can fit into a Falcon 9 heavy payload fairing, as a single large cryogenic tank, so you probably will want to make the tank emulate the fairing and take it to orbit, it will save weight using the fairings as structural and insulation instead of discarding them. Would say 4 F9 heavy launches will get the lot up there, with 2 separate orbit lifter units and tanks, and then probably a final set of spacewalks to provide connection to them so they can share fuel and power

Yes there are plenty of aero engines that use copper gaskets to seal, this one needs to have that gasket annealed, and also to have the cylinder and oil passage sections formed thicker, either with a set of shims riveted to the gasket, placing the rivets into the water jacket area, or bu using a press to form the copper thicker in that area, using a die set that displaces the annealed copper out slightly, thickening the area, then anneal again to make soft. Even a good number of 1950's era designs, with cast iron heads and blocks, that used copper gaskets to do all the seals, and where the head gasket kit was simply a set of cardboard boxes containing individual annealed copper gaskets, that you placed in the machined grooves in the block, and lowered the head onto them, fixing with the new bolts that came in the kit, and those were famous for not leaking easily.

The shops get around that $500 policy by waiting till they come back a few times, getting all the video together by person. The day it goes over the mark they arrest them, and then lay all the charges at once, so the total comes over that magic line, and the prosecutor will try them then, often with the additional charge being a habitual criminal, and if they went across state lines to a few stores, to changing it to be in federal court. Shops have a lot of cameras, and even more storage, and every part of the store is monitored.
Did see in a bathroom a emergency alarm pull on the wall, which was green, so non fire, and with a large sign above it, in 3 of the 11 official languages, that activating this alarm will result in both security coming out, and that also the cameras in the bathrooms will then have the recordings viewed, which it is strictly not policy to do by anybody, including top management, and security, to do otherwise. Also false alarm calling is a fireable offense. Of course, that alarm pull was broken, with an out of order label taped across it.

My BIL would travel regularly to Holland, and his hand luggage was his clothing, and his checked luggage was Camels. He only got stopped once, customs asked him why he had 50 cartons of cigarettes, and he replied for personal use, he was staying for 3 months. got charged 200 guilders as tax, and went through. He was selling them in flea markets for 20 guilders a pack, seeing as official price was close to 30, and making a killing, as he was paying the equivalent of 10 guilders for them. Loose ones were 2 guilders each, and, as they were non EU product, they were a lot stronger. those cigarettes paid for his 3 month stay, and the flight, and all the other money he made there was bonus, seeing as he had a hustle with a truck, driving ahead of the garbage truck by 3 streets, and loading up on antiques people were tossing out, wanting to put in Ikea junk. Those went to a garage he rented, and then he would hit the ferry, and off to the UK selling at antique fairs on the weekends. Yes a few cartons went with as well, the UK cigarette prices were much higher than Netherlands, so he would get a better profit. He smoked about 3 to 5 a day....... And bought Chesterfields, as a change from Camel, as well.

I did help take aircraft down to the bare plates, no more rivets left. You know a thing has not been apart in decades when you want to undo it, and it falls apart, because you are trying to undo fasteners that have been together long enough that they corroded into one. That airframe was eventually a set of broomsticks holding a wiring loom, and a pair of jacks, as the rest of it was either away getting sandblasted and painted, or was sitting on the shelf next to the spot, waiting to come back together. I did find some minor cracks, and had them repaired, and a new coat of paint put on, plus installed new mountings, as the old ones were barely functional.
Remember that the overhaul cost often is going to be more than the original new purchase price, which is why you often find commercial airliners being scrapped as this becomes due, simply because of the cost, plus that it can often take a year or more to complete properly. Only the military, and those with special purpose aircraft, that are otherwise irreplaceable, can afford to bear this cost. Same for engines, the smaller ones it is cheaper to replace than do the major overhaul, as the cost is almost the same for a small turbine compared to a large turbofan, due to the cost of all the labour and non destructive testing needed, plus the certification.

Thing is the US sweets and chocolates are terrible, and do not taste the same as the EU chocolates and sweets, simply because the US manufacturers use the cheapest ingredients they can legally get away with, while the EU manufacturers do the same, but have higher standards. Note Skittles are not chocolate, but are sold as a chocolate flavoured confection, as they do not meet the EU requirements, or the international ones, to be called chocolate, in that they do not contain any cocoa butter, no sugar, and no milk solids either, just small amounts of cocoa solids, hydrogenated oils and corn syrup, and lots of modified corn starch.

@tacfoley Yes, to make the ring a separate part would involve each half of the section having to be as strong as the full ring, and you would need multiple clamping points to ensure that the inner ring is not going to distort. Would add easily an extra half ton of steel to the grader section, and would require the rest of the frame to b stronger, the attachments to be bigger, the frame sections there to be thicker, and the cylinders to be a size or so bigger. All in all would be probably an extra 2 tons mass, and you then run into constraints on wheel loading, and driver training and working ability.
Easier for CAT to simply laser cut the ring as a single unit, then weld the outer brace on to it, and then have the side sections welded on, making a much stronger unit that is relatively light in mass. There is a laser cutting operation near me that makes those parts for CAT amongst others, and they will try to minimise waste in the sheet, so there is going to be a few other parts, that need that thick steel, cut out of the inner section before the ring is cut. All about maximising the usage of each sheet, to cut input cost.

I have some old photos of my mother, when she was around 18, just out of a camp in Siberia, and repatriated to British Persia. Then another when she was around 20, dating my father, with her friend who was able to translate between Polish and English/German as interpreter.
Till she died she never wanted to ever be as cold again, so of course moved to Central Africa, where summer and winter are just the wet and dry season, nothing else. Then South Africa, by the coast, where it never gets below 5C even in the worst weather. She wanted to keep the toes she had left.
The originals are tiny little ones, I scanned and printed them up for her to A4 size, and framed them, so she could look at them. Not many pictures survived the move south, and the long drive with whatever would fit in the 2 cars.

Center piece is there to keep the coupling from collapsing, easier to make it a separate part, than the make the more expensive mould, that you would need to have the polymer injection work, and not fill it with the green damper as well. Solid center on the mould to hold the part in place for the second run, making alignment easier for the robotic arm placing it in position. Likely made on a fully robotic plant, so as to keep consistency, and only a few workers who take the finished parts, do a final fettling and QC check, then place it in the bag, seal it, and apply the label for it.

My father was doing a delivery flight years ago with a C47, and at one of his scheduled stops ( well was the last one for that particular trip) he came in to land, and half way down the, what he thought was newly tarred runway (it was on the schedule for doing "real soon"), he hit a pothole in the water, as it was not tar he saw at the approach in the evening, but heavy rain earlier the day had resulted in flooding. The pothole resulted in the one landing leg detaching, so he made the decision to lift the remaining gear, as he was too slow to go around, plus would have an issue still with only one landing gear. Thus the plane duly belly flopped, both props went and bent, and he skidded to a halt in a spray of water, right at the terminal building, just as the duty ATC came out of the pub to fire a read flare.
None of the passengers actually noticed, even though they had, when boarding the morning, needed to use a set of stairs, but alighting merely stepped down into the mud. He called the airline, and the next morning there was another C47 flying up, loaded with a crew of mechanics, 2 propellers, the requisite jacks, tools and one undercarriage leg, plus some money to pay for their being there a week. Replacement plane flew the passengers on, and left the repair crew there to do the repairs, and the plane, arrived, a week late. Tough planes those.
My last flight on one was also interesting, in that the landing gear did not show locked, so there were some rather interesting minutes with the door open, and me and the flight engineer leaning out to look under the wing, so see if the gear was down and looked locked. Faulty switch on the gear, fixed after landing, and I got back on it to carry on as well. Undoubtedly the best landing I ever had in a C47, somewhat marred by the fire truck pacing us on the runway edge, foam cannon on the ready, just in case. But, as the fuel load was about 2 minutes at the time, the fire was likely going to be survivable anyway. Just we still had the original WWII seats and belts.

Probably replaced engine because that piston wrist pin wear was causing knock, and the ECU, thinking this was detonation, due to the timing on that cylinder, had pulled power way back. Then the lowered fuel input meant the cylinder was running ultra lean, and this, combined with probably a small carbon particle that got stuck on the valve, caused it to wear, and then the ECU carried on running that cylinder ultra lean, leading to the valve seat eroding as the combusting fuel mix kept on bleeding by. You can see the run marks of the metal being eroded away. Engine replaced because ECU told of misfire on one cylinder, bad knocking and lack of power, along with very lumpy idle. Compression test said cylinder really bad on leak test, so scrap engine instead of stripping head, because the used engine is cheaper than a strip, repair and assemble labour wise. Pump likely removed because it was faulty on the junkyard engine, probably leaking water, so to cut cost they swapped with the old one.

Insurance will pay it out, because replacement cost (likely what it was insured for, especially if it is under a year old) is more than repair cost.
I would guess the software fix was related to the ABS and traction control, which probably is the recall related to an erroneous rear wheel speed sensor reading causing ABS operation on one side. Part of the fix was a new software install into the BCM, and the addition of a pressure sensor switch to the ABS module, to detect rear brake operation, and thus to verify that the brake is actually being applied. Likely the old firmware would, on losing one rear wheel speed sensor signal, operate the other side brake hard, skewing the trike to that side, erroneously thinking the unbraked wheel was skidding and stopped, and wanting to regain control by braking the other side, without also verifying that the rear brake had been pressed, a fault in the software. The 2 wheel ones just get updated firmware, as there is only a single brake at the rear, and thus the BCM does get an input of brake activation, and there is only one wheel speed sensor, so no possible discrepancy in speed.

Part of that code on the ticket is a serial number, that includes not only the machine that printed it, but also a serial number of the ticket, which includes time and date of the ticket, and also a hash of the numbers entered in the ticket. The lottery has a database that stores all the details per ticket, so they can match the ticket serial number with the database, which proves the ticket is valid. Try to forge the ticket, and those numbers will not match, which is the common thing that catches the forgers out, as they simply use a ticket, and erase the thermal print on it, and then print it again, but the thing they cannot get right is the sequence number and the hash of the ticket, nor can they correctly print the barcode on the ticket, which is the same information, just in a easier to machine read format. The actual lottery numbers are the least important thing, that rest of the ticket is the thing that determines validity of it. Come with half a ticket, or where that is faded, and it is invalid, so check and collect fast, as thermal print will fade away fast, and is near impossible to preserve.

Hope you put some oil on those felt pads, otherwise those bushes are going to be very dry, especially after being scrubbed in the ultrasonic like that. They need 5 drop or so of 10W 30 engine oil added to each pad, which will then soak into the oilite bush and lubricate for a long time.
Yes please get some crimp on ferrules, especially for cables like that, they will come loose otherwise. The common crimp on ones can also be soldered if you remove the red, blue or yellow sleeve, and then use some heatshrink tube after soldering, to make them both more robust and able to fit small places easier. Cheap eBay pack (throw the flimsy horrible crimp tool that comes with the kit away, all you need are the crimps, and some decent crimp pliers) and you will get at least 20 of the most common size hole lugs, in all 3 common cable sizes. Then you see which ones run low first, and buy packs of 100 of them.

Very nice, was wondering why you did not make the shaft larger, then saw the clearance at the top. Would suggest as well getting a thrust race for the top, will make working with it better, or just turn a bronze washer to act as bearing, saving wear on the top of the machine. Like how the missing capscrew was replaced with the one removed for thread sample, when fitting that nice clamp. Suggestion would be to add in a small venturi in the feed line, so that you can have the option for air or coolant cooling, or by adjusting flow rates have coolant mist there, so that deep work with the tooling had the ability to remove chips fast so the finish is better. Just needs an air line and regulator, with non return valve in the air feed by the venturi, to allow this to run.

@iamdmc Aluminium and stainless steel, so no real issue with corrosion provided the antifreeze has protection in it for both. Expansion just needs a tank on the end of the radiator cap, and a 1PSI cap into a sealed bottle, or even just a simple accumulator, recycle a hydraulic one, as the expansion of the water in the system is going to be minimal, and probably can easily be handled by the PVC hoses expanding.
Would though suggest adding some sleeving to all those hoses, especially where they run in the chassis, as that is where they will rub, and PVC in clear has very little abrasion resistance, and will also rapidly age. Best to replace with some braided hose now that the concept is proved, and use silicone rubber braided Goodyear hose, which will survive decades there, and fit the existing fittings no problem.

The white centre is the element. The resistor is there to bleed voltage away. The sensor develops a voltage when vibrated, and the spring transfers it to the connector, and then to the ECU. The ECU will show knock, measuring the voltage developed by the sensor, reading up to 30V on the sensor for severe knock, and then adjusting to reduce it. The spring is the connection so it allows the disk to flex, as it is held in place only by the edge, and under it is a small hollow area so the brass disk can bend with the vibration, like a speaker cone. Exact same disk as is used in musical cards, held at the edge, and the voltage applied makes it flex, and produce a sound, but in reverse, the flex making a voltage. Resistor is there to bleed off DC voltage, and also so the ECU can tell the sensor is there, as the ECU applies 5V via a similar value resistor, and measures the DC voltage on the wire, to see the sensor is there, and the wire is not shorted or open. The signal is strong enough that the resistor does not interfere, you can test them with the tapping, after checking resistance is correct, by putting the meter into AC volt mode, selecting the 30VAC mode (as otherwise the meter autorange will make it display all over the place) and tapping it, where a good sensor should develop anything from 5 to 30VAC signal on impact, depending on where you tap, and also how it is held. Some of the sensors ( VW being one, but all that use a bolt through the centre are the same) are very sensitive to the bolt being the correct torque, too little and they do not work well, and too tight and the ceramic material breaks inside the housing, generating low or erratic output.

Yes, and most likely would be either apple, pear or orange juice, in big cans. By me those were supplied by the Greater Letaba Canning Cooperative, and the juice was typically orange, pear, apple, guava and mango, though we did occasionally get the odd can of Marula juice as well, though much easier instead to go outside and grab the fruit off the local trees, as there were quite a few of them planted there, as they are indigenous, hardy and bear quite a bit of fruit. Just beware if you get the liqueur distilled from it, it is smooth going down, but will also put you down as well.

Yes, aircraft engines can run on gravity feed of fuel, just ignoring that if the pumps pack up they will not run for more than a few seconds, mostly because the fuel flow is now not even enough to run them at idle, and the whole pesky injectors need enough pressure to put it in against the pressure in the combustion chamber.
Now fuel tanks in the wings are there to have useful volume in the cargo space, plenty of aircraft can have tanks in the fuselage, often things like tankers, where that fuselage is used to carry fuel as the cargo. Airlines however have that pesky need to move things, like people, cargo and baggage, so need that room to fit them in, instead of them sitting cramped up in the wings. So instead they fit the tanks in the wings, using self sealing bladders so they do not leak all the fuel out in all the rivet holes, and then, to keep it sloshing about, they use open cell fibre foam to provide both support for the bladder material on top and bottom, and also prevent sloshing around, but still allow flow down to the fuel pick up points.

For the car poor surface prep, plus did not strip down to bare metal and completely cover with a chemical rust converter to make the oxide a more durable phosphate, and also do the same on the inside of the vehicle as well. First remove the rust, make the material chemically clean, and passivate with a thin chemically bonded coating, then apply the primer, make smooth, then apply the correct automotive paints, and finish with the clear top coat. Has to be done both top and inside, though the inner section under the lining you do not have to bother with looking perfect, so it is faster there.

Yes send the repair bill to their insurer, and file a police report for malicious damage to property, and as the damage will definitely exceed the criminal threshold the company will be both paying for the damage, and also be sitting in front of a magistrate or judge to explain, with full video as well, exactly why they should not be found guilty, and have to pay. Accident would be if he was doing the entire road, but this is deliberate aiming, and also shows intent, in that it was done separately from any other work, and was also done by trespassing into the yard as well, off the mandated road clearing only.

Yes, easily 2 tons of static load in each of those bathrooms, and as well all those tiled enclosures, which typically are filled with either rubble and cement, or with actual poured concrete to make them solid sounding. Easily another ton there alone, and the kitchens at least 2 tons extra in mass. Tile typically, for smaller tiles, comes as 1 square metre, or roughly 12 square feet, 12 tiles if they are a foot on a side, and come in for some of them at around 100lb per pack. Add in needing 50lb of grout to put them down per pack as well, and easily you get to 2 tons plus.
Then you get the plumber needing to route pipes for drains and supply, and of course you cannot put them into the unit below, so they cut a channel through the concrete, going through all the reinforcing to get to the stack pipes. Cut and jackhammer the slot, bare steel left there without any form of treatment, and cracks all the way through the concrete. Plus stack pipes in the concrete, being from the 1970's I would say galvanised steel for the ones used to drain the roofs and balconies, and with threaded ends put together with couplers. Any pipe thread sealer would have rotted away by now, and the insides of the pipes as well, all that salt and rain scouring off the zinc, and the exposed threads rusting off the couplings, allowing water to sit in the concrete at each floor, making those columns weaker with time. Likely plenty of plumbing leaks, definitely going through floors. Would be interesting to see insurance claims for water damage over the years, seeing just how far each individual leak spread amongst units through the cracks in the floors.
By me there have been some who enclosed balconies, so part was filling the floor, we insisted on engineering consult, and specified low mass fills as well, not concrete, so the majority have gone for Pratletperl, as it is a very light additive, and makes for a thick light screed to cover the thickness for the fill. Same for remodels, especially if you were doing structural changes to any walls, load bearing or not.

@moeron9172 Yes do in the post combustion and post turbine exhaust, where the air is still hot enough, and has plenty of oxygen still to react with it. single injector there, cooled on the outside by the bypass air, and only energised with pressure when at altitude, so that it has enough time to cool off on the way down. Plus you can add in a purge valve, that will use compressed air to vent the line, and as the fuel likely will be solid at altitude, you would only need a little trace heater on the lines, that turns on after reaching 15000 feet altitude, and turns off and does the purge when descending again. Can be totally automatic as well, only a simple switch and light in the cockpit, or a message in the ECAM display, along with the others, and only flag a fault when it does have one. 20l of fuel will last quite a few flights as well, though the tank and pump will definitely need to be in a fire proof housing that will contain any leaks from damaging the airframe. Just going to be hard to fit, avionics bays tend not to have much spare volume these days, you can barely get in there to service them normally, and that space has to be there.

@e-curb Yes, but paying somebody to send them money, in a way that actually benefits them, in that they get the money either the same day, or next day, instead of in 14 days, is kind of stupid. It costs companies a lot of money to process cheques, in they have to collect them, so a driver is full time, or is not out actually doing other work. Then a clerk who opens the bills and enters the data, then another to handle all those to be deposited into the bank, and reconcile a while later all those RD ones, and then do the paperwork to have the account reflect, plus send the letter about the bounced cheque, which then has to be posted back, again the driver. Online payment boom, all done, saving needing 4 people full time to shuffle paper around, and then paying for archiving all that paper for 7 years, just in case there is a query. By me pretty much all bills are payable either by direct debit, or by EFT, with no charges at all to the customer, and banks have stopped accepting cheques 3 years ago, because there was too much fraud on them, and the banks were not willing to keep on losing that amount of money. You want a bank account, you open one online, or go get a gift card at many of the big stores and malls, and use that instead. But pretty much everybody, especially those on social pensions and grants, who have a free bank account from the grant agency, which is operated by one of the big banks, for free to the user, for this purpose. Easy to open an account with all banks, including virtual banks and a few nearly fully online banks, in that they actually use one or more of the large grocery chains as the branches.

I got told by an ex railways guy about the railways police pulling over a railways intercity bus. They asked for the ticket book, all 65 seats sold. Then they told everybody to get off the bus, and started counting. At 65 the bus was not looking any emptier, and they carried on counting till it was empty. Then opened the luggage compartments, and there were more people crammed in there. So, called for a few spare buses to move them to their destination, and the case went before the internal tribunal. All had paid full fare to the driver, who kept that extra money.
Tribunal and driver is merely told not to do this again, as his union lawyer brought up that they had not specifically told him they would be pulling him over. So the bosses solved the problem, and transferred him to a similar position, at same salary scale, in a tiny railway station in the middle of a desert, which had a goods train every day, and one passenger train once a week going through on the line. He was still a bus driver, but also the station was slated for closure 2 years ahead, because that once a week train did not stop there any more. He resigned, because his commute to work was around 4 hours each way, no station housing available.

Well, both sides of the front guides need to be painted, so that Karen has a good filming foreground. Yes long springs are a PITS, but you can probably get them made up for you easy enough, or get a roll of spring wire the right diameter, and use the big lathe, plus a mandrel that is shop made, and wind your own, as the tooling is easy enough to make out of a scrap of steel bar that fits the tool holder, and has a hole drilled through the length to feed the wire. Low speed, lots of lube, and new springs in a few minutes. Use the rattly lathe, because that will put a lot of stress on the tool post and the gearbox winding 2mm steel spring wire. 100m roll should get 2 4m springs out without issue, and only a little left over to make a few scale removal brushes out of it.

However the subscription model also has issues in that once you are on it, leaving is hard. Ask all those with photoshop, with a lifetime use ability, but they are unable to use it on a new computer, because Adobe decided to turn off the ability to register it and thus it will not run any more, unless you pay for the subscription model, which you do not really own. Myself I get along fine for my use case using free alternatives, even though I did use Photoshop for a few years, but the cost to carry on was not worth it for home use. Also some companies actively bought out the free alternatives, and after a few years went to subscription, and you are now locked in, and changing is both difficult and expensive, as they will thwart any attempt to export the work you have with them, using that they have copyright on the software, and also never disclosing how it stores the information.
MS did the same, you could buy Office, but now only can buy some parts, and for a very high price, but they will give you a subscription to the full set for a regular payment, but all of the parts are cloud based, and you never actually own it, or even have offline access to your information.

@billmoran3219 Think that all ran out during removal, seeing as there was not exactly any form of seal there on the piston, and to remove it you have to lift it vertical, so that all went, complete with chunks, to wash the arm and the fitter, plus the ground. wonder just how full of tramp metal the hydraulic tank is, and how often they are replacing hydraulic pumps because they got shredded from tramp metal, as normally the filter is after the pump, with only a screen to protect the pump, or a low pressure drop coarse filter.
Shows how cheap regular oil changes are, and also that regular oil sampling is worth it, seeing as this machine likely needed both a full hydraulic system flush, new oil pump and a new hydraulic block, plus all the other cylinders and lines are now full of glitter to wear them out. $100k there alone easily, just because you went cheap on the $100 monthly oil samples, and not changing filters on time.

The small taps are a "just how many of those per banana did you say I need?" moment. But they are great, the most common taps I have broken off in holes wereM6 and M8, so I have broken tap extractors in those sizes.
Only improvement would be to stamp CEE and the date on each one. The shorter length and the step makes it more rigid, the step keeps it on the tool post, and the lack of length does nothing for clamping force. Would say it does not need any angles relief on the sides either, button is wider, but the pocket does transfer load well. Plus now you have all the tools needed to make other more custom ones, probably you will have a job soon where these are too short, so need a really long one, which will need a deeper tool to stop chatter, and that would be easy to make now. Next will be a button insert boring bar, to hog out material in holes, basically this one on it's side.

My father had a garage in Central Africa. He had a customer who would send his Citroen 900 miles, on the back of a heavy duty truck, for every service. Truck needed because the roads in the wet season (half the year) were impassable for any passenger vehicle, even the Deux Cheval, with it's impressive off road handling. You are not going to drive when the mud is deeper than the height of the vehicle, and going off road involved a few axes to remove the trees, and possibly blasting as well, for the more obstinate ironwood and other hard wood trees. Dry season you has dry rutted road, which is why so much went via rail. Freight in very cheap, deadheading on the cars coming in to load up on copper anodes for export. Now they go via truck, and come down to South Africa to get to port.

The differences are easily explained by the differences in the blending. Fuel is never made with 95, 97 or 98 RON exactly, but is different components which are blended ( using an actual engine in the plant) to make a fuel that is around ( plus or minus a small amount, depending on the day and just how the output is at the time) the right figure. Your BP ULP and the ADSA ULP might actually have come from the same tank in the same tanker during delivery, but depending on what the actual RON of the rest of the tank ( and whether there was more or less water in the fuel) was easily explains the differences. The 97 and 98 RON fuels are exactly the same, blend wise, just a different additive pack ( or coloured dye in most cases to tell them apart in the tank) added at the refinery. I doubt they are all different refineries, likely all came from the same refinery in the vicinity, and just were delivered to the different garages in a tanker, either branded for the garage or plain white, depending on who was paying for the delivery. BP green tanker if BP was paying, white if the refinery was paying. Here all the same fuel, all delivered in the same tanker from garage to garage, so the BP tanker is a common sight at all garages, even non BP branded ones.

Belt squeal you can use belt dressing, but chalk works just as well. Tip for the VFD is to make a stand for it, because you will find a lot of other uses where you want a variable speed, so having a nice sturdy wheeled stand for it, to hold it at face height, with a lockable set o castors, a flat tray at the bottom, and a small er one half way up to hold parts, and a hook for an extension cord for power, plus a surface mount 3 phase outlet to plug the motor in.
If you want get your brother to take a 2 button pendant, put in a KM start stop assembly, with the VFD inputs for stop start, and a separate speed control pot, as the VFD will operate remotely easily. Short cable to attach, and you have all the options for a simple small remote control, and still have the display readable, or get a remote box and cable for that removeable pront panel, though that will mean putting the VFD in an enclosure, as the wiring is at mains potential on the display. Do not ask how I found that out......

Simplest part of discovery would be to ask for a list of all buyers of those clusters, and the in warranty claims associated with them as well. Those reports will show a pattern of water intrusion, even while still under warranty, and will probably be a pivotal part of the case, in that even new vehicles had this, and possibly multiple ones under warranty, thus adding to the case, and possibly leading to a recall.
You can redesign those clusters to fix a bad seal and still have original fitment, probably a different plug, and then a short pigtail that goes and connects to the original wiring connector, and a length of self amalgamating tape that is wound around it to seal it, or a shrink sleeve that does the same.

Smallest I have gone is hand blowing fusible link PROMS to repair stuff, though the other crew did do a lot of core memory repair, which did involve using a sewing needle and wire to thread the cores. Only a 16 by 24 array though, storing 16 words of data. There was an upgrade developed, that replaced the core with a Dallas battery backed 16k RAM, which increased the storage to a dizzying 32 words, limited to that because the computer it interfaced to only had a 5 bit address space, hard wired into the interface controller, and while it was possible to modify it to larger, the firmware would have needed to be recertified as well, plus find a spare few pins to bring the data out, and rewire the aircraft to bring it up to the cockpit.
Most of the firmware was literally hardwired into it, not stored in PROM, though there were a fair number of them, thus the need to every so often burn new ones, and we had no writer, but did have a lot of blank fusible proms, a test bed to check them, and a large collection of power supplies to do the verify and program voltages. Fun to fix a board which is a solid block of ceramic DIL packages, both sides. The original manufacture method was solder paste, glue the chips down both sides, rivet connector in and then reflow in a Fourinert bath at 300C, then spend a week with Xray checking on each joint, and a 2 week ATE cycle to weed out the marginal ones.

Linkage you are asking about is a universal joint. Cameras would have failed in high radiation mostly because the radiation damaged the semiconductors in the amplifiers for the vidicon tube, the actual tube itself would degrade slower, simply because of the larger mass of the photocathode meaning it would take much more to damage it. You would get ghost images from radiation off the video entering through the housing gap by the lens, but mostly for radiation all you would get was noise as the amplifier transistors got cooked.
Same for the digital logic making the video signal, where ironically a few generation older cameras, all tube based, would have survived for hundreds of hours more, till the radiation finally changed the values of the components enough. Those would have been seriously radioactive then, as you would had made a lot of highly radioactive isotopes of all the metal parts, and would have a lot of noise on the video from the radiation interfering with the actual electrode structures. But they would survive short term, a few days, looking into the most radioactive parts of the reactor, provided you kept them cool enough. But the failed cameras, once removed and cleaned externally, would decay back to background levels in a few months, as the isotopes created from the gamma radiation and neutron bombardment all have relatively short half lives.

@1dariansdad Get a lawyer, they put a motion before a judge for cellphone location and metadata (remember this is not classed as personally protected data specifically by the US Supreme court, as it is classed as data used by the phone companies internally for billing purposes, so is not protected speech) which will give them all the details for that day. Then at endpoints and traffic cameras simply request footage, and see the renter was driving. Then the civil case goes ahead, plus the renter now also has, after losing the civil case, now additional charges of making false statements to the police, plus insurance fraud, and a few others that can be tacked on. then will also have to pat for the damage to the rental truck, plus the replacement of the other 2 vehicles written off by the renters negligence. That rollover definitely had injuries, you do not walk away from that unscathed, you will have bruises, torn muscles, and back and neck damage as well, just not fatal.

@libbylandscape3560 Very much so, because in my experience buying a fancy fridge just means it fails in 5 years, about a month after the warranty expires. There are those that tout a 10 year guarantee on the compressor, but what they do not tell you is that the cheap steel they used to make all the evaporator and condenser, buried in the polyurethane foam in the case so there is no "ugly" coils showing, will rust through after around 8 years, leading to a gas leak, and thus the compressor will die. The 10 year guarantee also only covers the motor, not the associated control board, which, as a spare part from the dealer, costs half the price of the brand new fridge you just bought, before discount, and thus after 8 years, when the compressor dies, it also takes out the board, so you are in for a bill about half the cost of the unit new, and there is no guarantee on the repairs other than a 3 month one. Even then you change compressor, and 4 months later the pipes finish rusting out, because they were disturbed by replacing the compressor, and you now have a bill again for the unit more than it originally cost, let alone the $50 it is worth at best as scrap metal.
Used to be fridge compressors, at least from the 1970's till 2000, were the most reliable part of the fridge, almost never giving issues till the unit rotted out, or the case of the compressor rusted away. But around 2010 they started to cost cut, first winding the compressors for 100/200VAC operation, saving on copper wire, then changing to CCA wire, because that is a tenth the price of copper, and lasts around 10 years before failing. You used to find small motors were wound with copper, but now universally all are CCA wire, and it is used to replace copper wire everywhere, as it is cheaper, even if the price you pay is not.
Just remember that that appliance, you paid $500 for in the USA, was imported, shipped all the way from China, and the manufacturer paid all the shipping and import costs, but the 50% mark up was in the USA. Also the parts were from lots of other small suppliers, so that $500 appliance actually cost under $50 from the final factory, the rest of the price is mark ups on the price, from middle dealers and profit all the way at the end. Your material cost has to come out of that $50, plus the factory costs as well, and a small profit for the actual manufacturer. Of course they make it cheaper, because the buyers for the big retailers always demand that the new price is lower each time, never mind the quality.

Monochrome CRT you can get to 20k lines with ease, just requires a very small beam diameter inside the CRT, this determines the spot size on the CRT, and you can make a very small spot if you are prepared to have a low brightness. Colour CRT you could get 2k screens, but they were both insanely expensive and a bear to align, and would have colour fringing if you moved them at all, and also would have fringing with any ferrous metal moving nearby them. The most common use for high resolution CRT's was film digitising, using the CRT as a line source and then slowly scanning the film past the line, with a photomultiplier tube getting the video signal off the transmitted light. The resolution possible on the best was better than most film stock. Colour was done using a colour filter wheel or dichroic mirrors to separate the colours and handle them separately, the CRT providing the white light source to drive them. Simpler ones were used regularly to transfer film to video for TV transmission, using a variety of methods to get the video signal off the film at TV scan rates with the film running at 24FPS.

The one fibre installer we dubbed Digotel, because wherever they dug, you would find that every bit of brass, copper or scrap steel there, in things like meters, taps, water pipes, house numbers, manholes and such, and even gate motors, would be stolen during the day. Plus they would find every buried service, from water, power, including 132kV buried lines, sewer and stormwater, plus any other fibre or copper service, and damage or break them. After 6 months the city banned them from any further work, till they paid for the repairs they had racked up already. So now 5 years later on they are still not back. Saw one put a pickaxe through a cable, right at the joint. 11kV cable, blew the tip off the pickaxe off, but the operator was otherwise unfazed, the strong weed he smoked made him immune to that sort of shock. Took 6 hours for the metro crew to splice in 5m of new cable to fix it, though power was back within an hour, as they knew the substations either end, and simply moved the loop disconnect point to there instead.

@WrenchingWithKenny You are thinking of old generators, where you can get a failed voltage relay, that allows the generator rotor to be powered all the time, and then the one winding burns out from the current, going open. Thus the draw that will, because the engine generally will shut down at a preferred set of positions, depending on the cylinders holding pressure, so that you would get that open coil in position, and no draw, or get one that still works in position and a flat battery.
Alternators draw will be constant, because you have at least one shorted diode, and one leaking one, so that the stator is now always having a current flow. Leaky diodes will not be too much issue, but a leaky and a shorted one causes draw, though normally a shorted diode is nearly unnoticed, as all it does is reduce current capacity of the alternator, and the voltage regulator still controls voltage. Second failed diode kills the alternator, but before that the ones that is opposite the shorted one is getting very hot.
Had that before, one shorted diode, just a power supply that is a little more grumpy. 2 shorted on the same power rail it still runs, till it gets hot enough to burn out, which was a million dollar fix to order the spares, as the transformer came as a complete unit, as the cooking would destroy the entire inside of the equipment box, and fixing was going to cost more than that in spare parts. Was standard when servicing any of them to look for faulty diodes, and replace them immediately. I had a row of failed ones, used for spare parts that had not been totally cooked, for the others. My replacement power supplies came as ordinary untracked parcel post as well, despite being the price of a half kilo of gold.

@peterbodzak7078 Know of one where they were towing, and did not disconnect nose wheel steering. AC went straight into the wall outside the hanger. Radome came in for a check, undamaged, despite the big 10cm hole it made in the blast wall where it impacted, but the pitot static assembly sheered off, and went through what was behind it.
Box, electric control, did not appreciate having a tube pushed through it at the level of the internal chassis, slicing it in half while powered. Lucky there was a spare nose section from an aircraft undergoing major service, which was put on in around 2 weeks. Original one took 2 years to repair, as they had to strip it down to the individual panels completely, to get the damaged ones out.

New subscriber, and all great points people overlook. Especially about testing diodes, which people almost always, even experienced mechanics, overlook. Depending on the multimeter you can switch to AC volts, and some have a dual display, which will show both DC volts and the AC voltage on it, so that you can diagnose a failed diode pack without a scope. Others when in AC volts disregard the DC, so you get the AC voltage only. As well remember that there are 9 diodes in the alternator, 6 high current ones that feed the output, and 3 lower current ones that provide the excitation to the rotor, and those 3 also can have a diode fail. Most voltage regulators will have a terminal, or a place you can put a probe, to measure that field voltage as well, so your scope can test those diodes as well.

You also find a lot of furniture with the "real leather" label on it, but what they put, in the flyspec 1 point font on page 8 of the brochure, even smaller than the disclaimers about price and availability, and the return policy and warranty exclusions, is the type of leather used. Seat and back might be real leather, perhaps even from a cow, but the bolsters are horse leather, and the sides, rear and any other parts with a leather cover are actually fake leather, or vinyl embossed to look like leather. Thus only 2 hide sections per seat, and the rest is cheap fake, but your price is based on them both having real leather all over, and that the interior is actually made from real wood, not just made from pressboard cut into strips and used in place of the wood, and with urethane foam to fill in the rest of the volume.

Funny enough by me last time I was looking to change VW CV boots the cost difference between getting just the boot and the clips was only around $3 less than buying the complete CV joint itself, and as a bonus you get a new CV, grease, new nut and about a half hour saved per side. Just undid the nut, lifted the car, took wheel off, then undid the ball joint, tapped the CV loose from hub, popped it out and tapped it off the shaft, then new ready greased CV went on, and 5 minutes later I had it in the hub. Old joint was just scrap then.

@NicholasRehm Not likely, just that the computer systems are probably only going to be Intel 386 based at best for the core of the ISS, as those are currently the only, aside from some Motorola and MIPS parts, of around equal speed and complexity, parts with space grade reliability available, Laptops and other stuff they handle by having multiple devices, so a radiation induced failure is not terminal, and they do repair a lot of them by swapping parts around common devices.
Remember most of the control software is either running on redundant hardware with error correction, and no method to update it, or is running older versions of operating systems that are different enough that your common malware will not run on them. However nothing stopping somebody from doing a Stuxnet style attack, though that requires intimate knowledge of the systems and how they are connected.

@zgelrevol9682 Still not going to be any sort of delay noticed, as all of these programs will fit into the L1 cache in their entirety, and thus will all execute in 8 bus clock cycles, and the biggest delay will be all the calls to the L2 cache for the DLL calls, likely cached there as they would be needed for other processes all the time, plus would have been called to load the EXE itself. The biggest delay would be the tens of thousands of CPU ticks that it takes for the glacial slow (to the CPU, which would context switch after the initial burst of calls as the process is now in a wait state) IO process to both graphics memory, and to the GDI instance to draw the window on screen.
Probably all versions will have the window open before you have lifted your finger off the keyboard, and before the keyboard has sent the key lift code back to the south bridge keyboard controller itself. You might see a timing difference if you used a copy of Windows 98 (likely this code would run on it, though you would have to explicity use 16 bit code and change the linked libraries to ones that 98 worked with, and if you went further it would run on Win3.0 as well) on an original Pentium 25MHz, where you could literally see windows being drawn on screen, and Win98 would run very slowly.

Friend of mine in military was in transport. Had a military vehicle involved in accident, and a predatory towing company scooped it. He went there next day and asked nicely for it back, and got the massive bill, plus attitude from them. He left, and came back to base, and talked to his boss, and then went and got the wrecker ready, and arranged for 15 security squad members, fully armed, with bulletproof vests, rifles, tear gas, stun grenades, and attitude, to come with in an APC as well. He walked in, with them basically swatting the entire yard, rifles aimed, and putting everybody on the ground with hands behind backs. Then told the tow company they had 2 options, either sign this here release saying zero charge, or they all would go to military prison in the APC, and the vehicle would still leave on the wrecker. Sadly they chose option 1, as security was really wanting to do serious damage to that building, as a urban assault training exercise, and live tear gas grenades, instead of only dummy practise on an abandoned building they normally used. Funny how the attitude of the owner changed with 6 people in armour in his office, all pointing live weapons at him and his staff. Zero consequence if they had, against the law to tow a military vehicle under any circumstance, without authorisation from the controlling base top brass. Even the police will not do it, until they have gotten an OK back to do so, even to pull to the side of the road.

They think they save money, which short term they do, but long term it is really expensive. Bet they also complain the ute needs an oil change every 15000km, then complain that, because they drive on dusty roads, that the engines and drivetrains are worn to nothing after 100 000km, because they never actually serviced them using the right schedule, which is in the handbook, and is 5000 km. 15 000km is if you drive on tar freeway, no dust, no dirt or water, and never stop running the vehicle except for servicing. But this will get it out of warranty, and then you buy a new engine, or buy a new vehicle, both profit for the manufacturer.

There is an EPA fine for that, so you can easily make it a federal case. They hit during the day, drive in in a van, park, open the side door and slip out with the cans. Then 5 minutes later pull the full cans in the van, close the door and drive either to another spot, or drive off. All it needs is to have working cameras at all entrances and exits, and have them have to stop at a boom for a few seconds entering and exiting, so that you get good video of the vehicle, driver and number plates. Front and rear, and when you get the cases look through the footage for the matching vehicle next to the car, and look up the plates. Then if they used false plates also have a link to some ANPR, so that you get fake plates flagged driving in, and catch them fish in a barrel style on the way out. Probably pay for the system in collected parking fines that were ignored within a year.

My mother was collected 5AM, taken to the one already chosen, and then went to be washed, and then after the viewing into a plain coffin and straight to the crematorium. Funny thing is the most expensive coffin there is actually the one made from plain pine and cloth, no nails, no staples and no frills, all biodegradable, most common used for the Hebrew burials, where they take the going back to the ground you came from seriously. But she wanted burial at sea, along with my father, who had been in the house for a few years then. So off down to the beach, and they went out with the tide.
All was paid for there, and, once converted to USD, was around $250 all in all.

Thing is mechanical slide on rod is almost always going to win for reliability, speed of operation and power required to operate it. Solenoid operated valves are at their weakest force at beginning of stroke, which is precisely where pressure holding the valve closed will be at it's highest. As well fast operation means high current, and thus a lot of heat, in an already very hot area, making electrical failure very likely very fast. Connectors at that temperature and oil splash are not cheap either, for reliable high current flow, and are going to become very brittle very fast. Imagine having to change 4 actuators and wiring harness, per cylinder, every 50 000 miles as a "service part", because they will fail some time soon after that, killing an expensive engine controller as well.

@MrGonzonator The losses are to a first approximation constant, so the heavier the load the more power output, and thus the ratio that these losses contribute per kilowatt are less. IC engines are most efficient at a pretty high RPM, but unfortunately they rarely spend much time in this regime, unless you have a hybrid powertrain or a CVT that tries to keep engine RPM constant, where you can have a lot of design optimisation that makes for a very efficient engine over a narrow range, but abysmal performance out of it.
Most common on 2 stroke engines with a tuned exhaust, that has a very narrow power band, with impressive output, but a relatively poor performance outside that spot. If your engine is going to spend all the time either off, or at peak power, it can be very efficient as power source, though hard to use for a variable load like driving, but for power generation exceeding good, provided you always have a near full load on it.

@volf4o Funny thing is that when BMW took over Rover, they finally had a Rover engine that did not leak like a sieve from new, and the only started leaking after a high mileage. Maintain a BMW well and it will never leak, it only starts when you do not keep up on the little things and neglect regular oil changes. Seen plenty of BMW's of all types well into the 200 000km mark where, because of regular maintenance, the engine is still oil leak free and runs well.
Of course that is only now for the first 7 years, while the vehicle is in Motorplan, as the dealership will keep it nice, and bill BMW for all that gravy work. After the Motorplan is over you will cry at the cost, though the good thing is that there are plenty of aftermarket suppliers of parts that will fit the engines, some of them coming from the OEM themselves, just not supplied in the BMW bag and box, but otherwise identical parts.

They would be 3 phase transformers, so the 6 diodes in the rectifier module would be under a lot less strain than if it was single phase. As well with 360Hz ripple current the capacitor bank ( probably rated for 800VDC and running at around 600VDC in use, using 400VAC phase voltages, as most IGBT devices are 800V rated) can be quite large, but the ripple current will be low for the power. More for riding out short mains power failures, and still having enough energy to safely brake the car string to a stop even if the power goes out totally, than to store the energy to drive it. The power required is I would guess around 500kW peak, but only in bursts, and having 2 big transformers is to have redundant network connections so one going down ( or being off for maintenance) does not stop the ride. They probably have separate rectifiers, fuses and only connect to the main DC bus via some big fuses. Smaller transformer is probably only powering the ride lights, aircons and the park area around it, not the ride direct, though it might do the control room and passage lights. Cooling fans for the ride will be powered from the big transformers, 400VAC 3 phase motors are very much more reliable than 120VAC single phase ones, and can be much smaller for the power output.
You would also have associated with the ride a very large force air cooled resistor bank, to dump the power the linear motors absorb when they are used as brakes. In that control room you will have a resistor bank capable of dissipating 1MW or so of power, though it only has to do that at the end of the ride, or on emergency stop conditions. It will be direct on the DC bus, and use another big power controller ( more IGBT modules) to keep the bus voltage during braking from rising too high.

Diesel oil in a petrol engine is fine, the extra detergent will remove a lot off sludge and varnish off the engine, though you would be advised to do a second change of oil and filter after a short interval, probably around 300 to 500 miles, as the oil filter will be full of all the sludge and junk removed if this is the first time. Lots of farmers only keep one oil on the farm for all vehicles, and it will be for the diesel engines, the rest get the exact same oil. Knew one who when we looked into the cover that top end looked like it was barely out of the factory, despite the vehicle, VW Golf, having been driven for over 200 000km already, and it had been getting farm oil changes only for the last 3 years or so, being a second hand vehicle bought for the son, and had come with a lot of sludge in it. 20W50 was the oil needed, but all got the same SAE30 HD3 diesel oil, that arrived there in 55 gallon drums.

Pretty reliable, once you remember the correct operating condition for the contacts. They run best with 24V across them when open, and 20 to 100mA of current when closed, which helps by keeping the contacts free from oxide, as they wipe across each other, and this make good metal to metal contact. You get a totally different switch, with thick gold contact faces, for low level signals, such as those from the hundreds of thermocouples and platinum resistance thermometers that were used to measure temperature, and the hundreds of bridge type pressure transducers as well.
Those AZ-5 switches look like they break before make, so while you operate there is a brief period where all contacts are open, so as to prevent shorts. Others will be make before break, where you do not want interruption, while say changing the range on a meter.
The mirror galvanometrs are very interesting, with them not only showing up as readout, but also being a simple interface to the SKALA system to be able to input state information without needing complex extra converters, and also associated programming on them as well to set limits. Just built into the existing display, annd an easy way to show if nominal, or which way the deviation is. Likely there is a further phototransistor there that also acts to inform that the lamp has failed, and print it out for a repair operation. 28VDC lamps, run on 24VDC, probably with a series resistor as well, so as to drop voltage to around 22VDC, so leading to greatly increased lamp life.
The type of lamp is classed as prefocussed beam, as the optical path is fixed in the lamp construction, so that in use no further focussing is needed during changing the lamp, as all of them are adjusted in the factory to have the filament in exactly the same orientation and plane, so you simply swap the failed lamp out, and close the panel up.

_Plus you can can lard and fat, or vegetable oil, and the cooking during the canning provides a great deal of shelf life as it sterilises the inside contents. Often you also would find corned meat that is half fat, and an enterprising cook will render that fat out, and save it for the next meal instead, so getting a good deal more out of the single can. Canned beef, canned horse, canned chicken, canned pork all would be there, along with the canned hard tack as well, and square cans, as those packed better, even if they were more difficult to make in a factory.

Friend landed up in hospital after that. Go visit him after the day, and he asked just one thing. Take the shop van he drove to hospital with, drive to the base, get the section keys out of the duty room, and go into the locker room, get his clothes, his car keys, with his room keys, and most importantly his cigarettes and wallet. Did that, left the work van at the gate inside, and drove his car back to him. Next day got off the bus at the gate, and drove the van back to the section for his boss.
2 weeks later discharged, after giving birth to a 5 pound baby. Doctor tried enema, soft food, safe laxatives till eventually RN grabbed him, told him to swallow this, and to never tell the doctor ever. Rough and tough laxative, normally given to horses to "get them moving", and an old home remedy. 3 hours later Atlas moved the world.....

I entered a competition, and won a waterbuck. Bit bigger than a cow, and it was cut in half, but both halves still were dragging on the cold room floor. local butcher did the preparation, and there was around 800kg of wet meat after preparation, as I had to also pay for 2 pigs worth of fat to add to the sausage. After drying (a whole garage of wire, paper clips as hangers, and a 2 week wait) there were a good number of garbage bags of decent dried meat, even though the cat got in there and had eaten it's own weight in the wet meat. Around 200kg of dried meat for each of us, and it took 2 years to finally finish all of it. Coworker won 2 Wildebeest, and his solution, same butcher to cut it up, was to simply order 6 chest freezers on his account at the local shop, and filled them to the brim with the packs of meat. Still not enough space, so we all had a nice set of steaks for a week, because the garage was now filled with freezers.

There are actual standards for laundry detergent, often the ones the military have set out for their buying, and NIST has both the standard laundry load, plus the standard detergent dose, available for sale. Same for toilet paper, the standards cover things like dry strength, wet strength ( plus times, amount of water per sheet and such) and the amount of time it should take to dissolve as well, so that it does the job, but also dissolved in the sewer system to not create blockages. Note that washable wipes do not actually dissolve, they stay intact, and are the major cause of sewer blockages, along with sanitary pads and tampons. Those should be disposed of as dry waste in the household garbage.

The RAM chips have a weak NMOS transistor in them, which is tied to 12V, to act as a pull up, and to also supply a low current, as it is a very small channel device, so it has a high resistance. Smaller than using a polysilicon resistor, and as a bonus when at 12V it also acts as a clamp diode to prevent overshoot. The 470R resistor is there to damp down the transmission line of all the chips together in a long row, dissipating the spikes that would otherwise drive the chip inputs into clamping to the power rail, and thus also having a chance of turning on the parasitic PNPN thyristor inherent in almost every IC. Made by the junctions used to isolate parts, and, while the transistors made in that way are very poor, they do normally have a gain a tad over 1, so the 2 PNP and NPN structures can act like a thyristor, as they will latch themselves on, shoring out the power rails, if you exceed the allowed input current, typically 100mA, but in the data sheet you will see in absolute maximum 50mA, as pretty much all will not latch up at 50mA unwanted input current into the internal protection diodes that are part of these transistors.
The resistor, along with the capacitance, damps down the rise of the enable pulse, and you still see this on your DDR memory, as resistors, typically 10-33R, in tiny arrays on the address and data lines to the DDR sockets, normally 4 resistors in a tiny package, that perform this function, though a lot of the DDR chips themselves also incorporate the resistors into the die itself as well, as that improves the speed at which it can operate. Done on all the address, control and data lines, turning them all into transmission lines, so all have to be the same length, so as to not skew the data applied, as 10mm extra trace on one line will mean you lose 100MHz, or more, in maximum clock rate you can use, as the chip will start to get errors, as the data or address does not arrive in step on all pins.

Not really, the field would very likely also affect operation of the craft itself, so much simpler is simply to have light mass shielding, or something that you need to take with do it as well. Most likely thing is that there will be a water tank that is also a shelter, with the water acting as shield, and also the required food rations can do the shielding as well.
Probably there will be a thermal shield used on the spacecraft that does triple duty, acting as sun shield, and also as a micrometeorite shield by having multiple thin metallised mylar layers, and acting as a radiation shield by allowing the high energy particles to impact it, and the inner layers handling secondary emission, then the spacecraft hull itself acting as a barrier, with the rations packed so as to absorb it's secondary emissions. The dried waste would also be packed back into the same spot, so the shield gradually changes from food to poo as they travel along.

Louis has the perfect sign for Blackberry, right above where she was sitting, the Danger Peligro red tape there.
But anything made in the USA electronics wise will also have a tariff cost added to it, because you cannot get all the component parts of anything that are purely made in the USA. Your PCB will use 3m epoxies, components of which are made world wide, and imported to be blended and formulated in the USA, the steel used for the cases and internal parts came from China, India and other countries, the aluminium ores for the parts all were mined, and for the great part refined, outside the USA. The copper came from mines all over the world, the silver used to make the MLC capacitors is a blend from all over the world, the gold used for the plating came from either Russia or South Africa to a great part, and all the cobalt and tantalum came from DRC mines, conflict minerals to a great part, despite the claims otherwise. USA did a great job exporting all the dirty process work to other countries with lax legislation (which is why India is the ship breaking capitol of the world, even the US Navy uses then to dispose of ships that are too expensive to break up in US ports) and lower cost of labour, and this was never actually used to lower prices, instead making the 1% richer, while cutting labour costs, and making massive pools of upper management that, in most cases, know nothing about what the companies actually do, and are only ever looking at a long term forecast of the next quarter for profit growth.

Also the 250VDC line power would wreak merry havoc with old phone copper in the cables, I had plenty of call outs for ISDN where the solution was to swap the pair in use with another one in the same cable to the local street box, which was actually in the basement of a building across the street, seeing as it was government owned, and the post office used to own the phone lines. they had a few racks of 3M pale blue punch down blocks, all dating from the 1970's, and the 50 pair feeding the building landed up in 3 rows of the outgoing cable, while the exchange side used a few 500 pair lead sheathed cables. Now these cables were old, over a century in service, and that basement was under sea level, so they all had had the steel sheath rot off them decades before, and not really were good at holding water out.
So either swap to a good pair in the 50 pair, and hope that it would last a while, or the 50 pair was good, then you swapped with another pair in the 500 pair units, and hope it would be good. You know a cable is bad when you are splitting pairs to get 2 good wires to use, and eventually we were down to having DSL on the one good pair still there, with POTS on all the good wires in the others, and the TELEX line was sitting with the least noisy bad wire, and running with SWER connection, as the sheath was still mostly good enough to provide a common when bonded with mains earth. When cancelling that telex line I was told by them not to return the equipment, as they no longer wanted it. Turns out it had not worked in a year, failing quietly.

@Kmac-oh5yj Going to guess the 80% is so as to not interfere too much with the user experience, as Win10 will use unmetered connections to do a distributed update, sharing the chunks downloaded, and not yet installed, with other users in the same IP range, so as to reduce total bandwidth on the MS update servers having to serve multiple copies, even via a caching CDN, to a number of machines physically close to each other, or for corporate in the same network.
Gets the updates out faster, but needs less bandwidth in the large long distance links, by getting it locally. You can disable it, or make it less intrusive, by making all your connections a metered connection, but will likely miss some optional updates, unless you actually check for them.

@SergeantExtreme Exactly, the buyer had paid, and returned the goat. The fair had the cut of money, but instead unlawfully claimed the goat was stolen, and then had law enforcement come and take the property that was not theirs, and destroyed it. Pretty sure the 4H lawyers have told their clients they are up the creek so far without a paddle that the canoe is also not useful, and that they had better take any settlement offer, no matter how poor, because the court will very likely take them for much more, and also tack on hard time as well. At a minimum they are being charged with filing a false police statement, lying under oath, destruction of property and receiving stolen property. If any of them are in any other way in a job that has integrity standards, they likely also face disbarment from there as well, and revocation of the right to practise as well, along with being terminated without any compensation.

@argunberkedogan168 Also remember they sank in water a lot warmer, so the steel was not as brittle, as it is a non linear relationship between the brittle failure tension and temperature, with a reasonably sharp transition temperature where the strength drops off rather rapidly, and thus the steel passed all QC testing when at room temperature, but cool it down to below freezing, even slightly, many samples would be considerably weaker. But other seemingly similar batches, with lower levels of impurity, would pass, it really depended on exactly what went into the furnace, and exactly how much sulphur was in that particular batch of coal that was used to reduce the iron ore that day.

@Today_Im_Living Baking and cleaning was to get most of the oil out of the cracks before repair, as it would otherwise add in a lot of carbon when welding, making the resulting cast metal be mostly iron carbide, and this is not strong, but when dissolved in the plain iron matrix in small amounts it prevents cracks from propagating, by fracturing and keeping it from growing. You have to do the bake and clean a few times to get almost all of it burnt out of the casting, so that your repair is almost the same composition.
This casting that failed likely is actually cast steel, thin sections and large surfaces with thin section, which in pure cast iron is incredibly weak and very easy to crack. You make a steel alloy with carbon and other metals in there, which makes the performance better over plain pure iron, with large carbon inclusions which stop cracking, but your material has to be a lot thicker to have the needed strength. Cast steel is lighter for the same strength, and very little is actually made these days with pure cast iron, as a blast furnace only makes steel, and a scrap smelter also really makes steel, burning out the excess carbon and such from the metal, and you add in the desired things, like silicon and manganese, as extra material to the charge. Making pure cast iron is a slow process, not really done, when scrap steel is so much more capable and cheaper to boot.

Well, the 3 colour tube projection TV sets have a non shadowmask display, though the front screen is lenticular to provide a brighter image in the forward view by concentrating the light in that direction in rear projection sets, the ceiling mount ones use just a diffused screen ( or one with a reflective layer to provide optical image brightness gain to the centre for the same reason, higher perceived brightness for the same CRT brightness) to scatter the image in the room. Line resolution in a mono CRT and rear projection 3 CRT set is more to do with bandwidth of the video circuit, or how fast it can go from one predetermined brightness to another predetermined brightness ( typically 80% to 20%) and then how many of these cycles it can do in a single horizontal line before the difference between the 2 levels is no longer displayed. Thus you get the 500 odd pixel display resolution, which basically translates to the roughly 7MHz bandwidth the TV channel has allocated to it, the set cannot display more lines than that without exceeding this bandwidth, and this is the big reason for the resolution. Vertical it is fixed by the number of lines in the interlace, with the 2 half frames each drawing an image with half the lines, then the other half of the frame filling in the image in the blank space between the lines drawn on the other half of the frame. Overall it looks like a single image, but it is 2 with a line offset between them, the eye integrates the 2 half frames into a single one.
With monitors that are not TV sets you can get higher bandwidth, up to 70MHz or more for the last of the CRT monitor displays, which meant you could get much higher resolution, allowing you to use a much finer pitch shadowmask in the CRT to get a sharper image, though the trade off is both more complex alignment in production, more complex drive circuits to get the beam to stay aligned perfectly in all the positions it scanned on the display, along with the smaller phosphor dots meaning you had to drive them with higher power to get a bright image, thus the big risk of image burn on these CRT units. CRT displays also used an aluminium sputtered backing on the phosphor layer to reflect light back to the front instead of losing it in the inside of the CRT, which did not affect the electron beam, but which doubled the brightness, though the thick dark glass reduced this again to give increased contrast ratio on the image..

@SAOS451316 Propellers will survive a long time, and the anchors will soon enough also have the chain rust through, dropping them into the ooze, where they will, along with the ceramic parts and the bottom hull, survive for centuries, buried deep in silt, and gradually in limestone. Also things like lead sheathed cable as well, the lead protecting the inner insulation somewhat, and the copper cores doing the same, so the main power lines will still be there in some form after a few centuries, though the steel wrapping will be long gone. Junction boxes as well, steel casting long gone, but the cable in the lead wipe, the ceramic insulators and some of the brass still there in the bitumen fill.

Had a similar thing, except the refill was a blend of colas into the tank, to get enough to get to the shop down the hill, where water was available. Sad thing was that there was an urgent "DO This NOW" recall for the hoses, and the vehicle had been at the dealer for a month already for other things ( minor things, like oil leaks, seat failures, failed electronic modules), but the urgent recall was not done, despite the hoses having been sent already to do it. You know you have a lemon when the dealership people thought i worked there, because i dropped it off so often, and also that it had it's own demarcated parking bay, right by the office in the workshop, right at the front of the long rows of Freelanders, all stripped, awaiting new engines and transmissions to arrive.

I had the opportunity to watch that air to air refuelling, and it is very stressful on the pilots, even in smooth clear weather. Would hate to think of doing it at night, in a storm, as even in the smooth air the new pilots took a few attempts to connect, and the one finally did so, but was not watching his relative velocity, so drifted to in front of the tanker.
Corrected with full speed brakes, and in the tanker we all had a jolt as that pipe disconnected. The valves are not meant to close so abruptly, so the aircraft was gently banking away, nicely shiny and with a instant full wash in jet fuel, to go get into the correct envelope to do an in flight restart, because that sudden blast of fuel had flamed his engine out nicely. 10 minutes later he came back up, connected correctly, got his positioning right, and got his remaining fuel pumped in in just under a minute. You only need a minute or so to fill up, those pumps move the 2000 US gallons needed to fill you at a pretty high pressure.

Yours has that high a rate. By me they got the rate to 90%, by simply dropping the pass mark to 20%, and also by riding the curve so that 90% will pass, and then simplifying the syllabus as well, dropping all those hard subjects like math and science. Then wonder why universities have a first year that is essentially remedial school they added on, to weed out 80% of the initial intake, to solve the issue that the government said all who passed could go to university, and they would have the free edukashun. Oh yes, and teachers with multiple cases of having children with the students under them, as young as 12, still teaching.

Likely you will find there is one inspector for the entire state, and the state simply does not give enough budget to fix any bridge. Likely the reports are there, but have been put on the bottom of the pile for approval to go out to tender, and after that they go back to the bottom of the pile for approval as well.
I would say yes one of the base posts gave way from simply being eaten away by corrosion, and the other 3 simply could not handle the sudden imposed load and failed. The buckle in the middle was likely the last one to collapse, briefly holding up the section, and then the top simply broke where the stress was greatest and the corroded understructure was the weakest. The middle of the roadway collapses also the same, years of salt corrosion that ate the metal away, and with the one side collapsing the roadway followed, and on impact simply snapped in the middle from inertia. Likely the temporary bracing either tore off, from no longer having material at the parent beam to support it, with it having contracted from the cold, and the extra snow load caused the base of the weakened beam to buckle slightly, providing that extra 5cm of motion to tear it out from increased tension. Braces were stronger than the bridge at that point.

Any other manufacturer would have been using 1mm steel, and the tack welds would have been all the welding done, relying on paint to hold it together. But CEE puts the same mass of weld down as the metal, and double the thickness of metal.
Tip for the weld blanket is to grab some clothes pegs, or bulldog clips, to hold it to the extractor bottom. Will help keep the overspray down, and make it easier to clean up. Would also suggest putting an extension cord on the base with the extractor, to save looking for one each time. Long enough to reach the plug, and it will always be there.
Cutting saw if it is single phase motor time to change the capacitors, or the start contact is worn out. If 3 phase you have dropped a phase, either in the plug, or more likely in the switch.

Insulation can be fixed, just use thin 2mm sleeving, and slide down the wires, to put the insulation back. Those windings can come out though, either there are screws hidden under the paint, or they can be pressed out.
The switch as well should still be available, just look for the current model, and then get it brand new. So long as it has the same toggle diameter and body size it will work, they are still being made, or are available on the surplus market, though just as a generic switch.

Friend went to collect an illegally towed military vehicle, and they wanted money. He went back from there with the invoice, and instead his boss called base security, and he came back to collect. just did not have any money, but instead the base wrecker, and an APC loaded up with 15 fully armed, with live ammunition, tear gas grenades, and wearing full body armour, security personnel. No handcuffs, they were not going to arrest them, the towing company got told the first one to interfere would be shot, and the rest would be gassed. 5 minutes later left with the vehicle. Security was glad for the exercise, they had not had anything other than practice for months.

@Ms666slayer True, I saw a Carrera 4S get T boned, and bent into a banana shape, along with being pushed 50m down the cross road. Driver uninjured, despite the impact being on the driver door. All airbags worked, the driver only had minor scratches and bruises from airbags and the window glass shattering. Despite that, that door still opened, closed and locked, though the 3 day old vehicle was a write off. Fiat Uno that hit him was crumpled up, driver needing to be cut out of it. Also uninjured, because he was both high as a kite, and drunk.

@willford7717 To be fair to company coffee, it does taste crap even when fresh, simply because I will bet you nobody has ever stripped the machine and cleaned the basket, or even the carafe, let alone run descaler through the water circuit.
I do go to a place where they have the automatic machine, and the first thing I do there before pressing is run the cleaning cycle, which puts out a lot of nasty gunk every time. Then select espresso, and then cappuccino, and pour the first into the second. Only ever tried the stuff they call tea once, it tasted terrible, sort of vaguely tea like smell, but it was definitely not a good tea at all.

There are plenty of cases of the feds accepting a file, and rejecting it because it is too thin, so the filer simply printed it single sided, double spaced, double size text, and put each chapter heading on a separate page, and every image on it's own page, without changing anything. Making it double the page count, and this one was accepted and filed, never read, or ever used.

Pretty sure one of your viwers is an electrician, and is near you, who can do it for you. After all, there is already 230VAC power to the carriage, there for the digital readout, so it would be trivial to tap into that, and put a weatherproof metal Aus style socket on the back of the carriage, there by the connection box, to allow you to plug in the light, or any 10A max item you might need on the carriage in future.
As well good idea to take that slack in the cable out, so it does not act as a massive swarf collection unit, and also to get some nylon air line, and slip over the cut cable, before you put the plug back on, to provide a smooth surface so it does not get chips in it, and to keep the cable from getting full of coolant and gunk with time, as those armoured cables are not really waterproof.

Lot of the dealerships by me do that, video camera all around the vehicle, inside, under, top of roof, in engine bay, then fill in the paperwork, and what is in the vehicle ( spare wheel, jack, tools etc) plus noted on the entry doc of all dents noticed. Then it goes in for service. When finished it gets detailed inside and out before being parked in the yard. Every afternoon at 5 before close, after the service department is already closed for a half hour, and it has been swept and neatened up ,all those vehicles outside come and are jenga'd into the workshop itself for secure storage overnight, so the lot outside is left empty. If they have to park them on lifts and then fit them in , it will be done. Even though there is 24 hour security, alarm and cameras this is still cheaper than having to pay for damage because somebody waited for the guard to be past and on the other side, and steal off tyres from 3 or 4 vehicles.

@8180634 Exactly, the pay scales they would have to pay them are more than the budget allows, so the posts are advertised, but none of the experienced applicants can pass because they will cost too much. So the post stays open, and that is because they only want to pay for the lowest experience, but want 10 years of experience for that price. Funny thing is that when you look at the entire pay structure, more than half of the money goes to top management and the boards, who would easily be trimmed to half with zero problems in the most cases, giving enough to double the teacher pay and number of teachers as well. But they would rather fire teachers, get inexperienced ones at low cost, and dump them after 2 years for new cheap ones. Now there are no longer new cheap ones, they are running out of ideas, so use legal slavery instead. I know most new teachers would probably be better off flipping burgers, lower hours, less stress, more money, but they think of the job as a vocation.

Would say that the inverter has to turn on the cooling system eventually, especially at high load after a while, to cool down the inverter section, which is just using the standard input PFC and active power control circuitry, so adding it on was only a software change for the designers, as the semiconductors are already there, along with the filtering chokes, and you can make the power converter stage do double duty just with some clever design. That they make an adaptor is good, but really that needs to have the EV cable integrated into it, using the communication cords to do the output connected sensing, and then have the socket remote, so allowing you to have it actually waterproof, and leading to a dry place. Likely the inverter itself also has ground leakage sensing, part of the input protection, so it will also provide protection against you touching the live conductors, so you do not need to have a RCD in the power output.

Exactly, shortest distance to move the property entrance, and thus the billing entity, as the land itself is likely all one, just had a boundary line drawn through it years ago, after it was subdivided into lots, and his parcel, lot 23 of 55 of the farm whatever, got that arbitrary line drawn down the middle of it, to make the surveyor's job easier instead of a mass of Gerrymandering of the boundary, and subsequent decades of squabbling in court around this.

@jamescollier3 Not likely, that would involve actually spending a lot of money, that is much better employed as dividends to the activist stockholders instead. They will however cut every division by at least 10%, and sell off and outsource every single thing they can, because that is a short term massive cash influx, and thus dividends, that they siphon out immediately, and also use projections to get massive cash influxes and loans, that also get put in the dividend pool. then after the share price is at a peak they slowly start to divest, till they are completely out at a massive profit, leaving a husk behind.

The law should be that the HOA has to go before a judge to get the power, and that they need to have proof of service on the homeowner of that case. That is the case here by me, with a whole host of laws covering HOA's and COA's, with them needing to go through a lot of hoops to get before a judge.
I have been the one starting that, took nearly 5 years before the case came up, and i had sold and moved a little before, but the tenant that was there came to court, absentee owner, and had forged a rental agreement, but the agreement was not at court, because i had phoned the lawyer who said they had witnessed the signing, and asked if he was willing to stand up in court and say he was a witness to this, because i had dozens of letters, hand written, by the actual owner, all signed with his signature, and even to me that signature would not be a match, and was he willing to bet his registration on that. Case came up, judge asked the tenant if he had anything other than verbal, and then told him he had no standing, and 30 seconds later default judgement.
Off to auction, where it was sold one day, then buyer came, saw how it looked, and got out of the sale, as the sale was 10% down on hammer, and balance within 14 days, so he waited out the clock, and lost his deposit. Second one bought, came to see with some "assistance", and told the tenant that it was now 4PM, and that at 6PM he would be leaving, his choice would be to leave willingly by the door, or not so willingly, in which case door or nearest window. He left, and after the sale the lawyer for the BC landed up with a lot of money. Went to all the other owners, I knew all of them, and told them to bring all the bills through the years of damage to property they had from the last lot. All got paid out of the money, and the lawyer followed the legal trace route, 3 months get another trace from a PI on the owner, paid out of his money, till the money was all gone. Hard to trace a person when the last known location was Morocco, and he was there not for visual tourism, so was keeping off of visible places.

@ohnosmoarlulcatz Well tracking devices on hybrid vehicles require special training to install, because the average installer is not too bright, simply because the job rarely pays much above minimum wage, and hybrid cars often have high voltage wiring in those looms, and cutting the wrong wires can result in the battery controller module, buried deep in the battery case, disabling the battery permanently, by remote blowing the high voltage fuse assemblies, which are also not easy to either get to, or replace.
Most are installed using no tools more than a screwdriver, side cutters and lots of insulation tape, and by twisting the wires together.

I remember seeing the first models of the "upside down Atoyot" pick up that arrived, and were offered for sale. Engine is "sort of" Isuzu, in that it looks identical to the Isuzu engine, but just nothing actually will fit, all are 1mm or so different in dimensions. Drivetrain is also sort of Atoyot, but the thing that is memorable is one of the first ones that was driven off the lot, and as he started to drive the drive shaft sheared off the gearbox, and dropped onto the road, making it sort of pole vault. Turns out they cheaped out on the bolts, using mild steel, off the cheapest supplier, bolts, not the correct high tensile strength bolts they should have used. Had to replace all of them on the vehicles off the lot, as the first model, sent for testing, actually did have the bolts correct.

Please explain just how you are going to escape when there is 400 bar of pressure on the outside, trying to get in. Yes no locators, and GPS shockingly does not operate underwater, and in general locators rated for that depth are still covered by US ITAR regulations, so not something they are going to allow into civilian use anyway. Yes late owner was ignoring many basic safety rules, and did not want to test a prototype to destruction, at least not willingly and in a controlled manner, and ignored the stress of running carbon fibre composites too close to the edge. But with the implosion you can be sure they absolutely did not know it was failing, the pressure pulse travelled faster than nerves can transmit information, and the brain was destroyed before it could even start to realise there was an issue.
Those end caps though likely are the things they will recover, as they likely are the clue, they probably did not fail, though the attachments to the composite are likely what did initially fail. Rest will be left there, unless they want to bring up the entire thing. Reminds me of Arthur C Clarke's book, The Ghost of the Grand Banks, which has some eerie similarities.

Gap was critical with points and regular coils, but with modern ignition systems they are well capable of firing the plugs to a point. Antiseize is good, but yes a thin film, not blobs, as the thread will remove it at the contact points, and the rest will fill the voids, which is what it is there to do, fill up gaps and not allow rust to form. I use a white Loctite anti seize on boats, and where you have corrosion problems, and it works well to keep things from sticking, even in sea water. Boaters that do not use it generally replace motors every 2 years, because they turn into solid blocks of corrosion.
Aircraft you use a yellow anti seize compound, which is specifically for aluminium, but it is a very expensive product, and I used it by the gallon. Worked, only took 6 of us with sledgehammers to remove the leg strut from the housing, and it was slathered with that from the last change a decade or two before. No compound, and we would have had to drill out 600 rivets, and replace the entire strut housing, and rivet the new one in place. We did not want to take another month on that service though. 2 in stores though, from the 1970's, in steel containers and in lots of cosmoline. Old stuff was hard as cement though, but the new strut went in with lots of it after cleaning out the housing well.

@Jack_Russell_Brown Well the one explosives facility has no cleaners, the staff there do cleaning as part of their job, and then the final dumping is done by a hazmat contractor, because there is a good chance the garbage is explosive.
Another place the bus driver, a regular municipal employee, who drove the bus route that ran there, was required to have a top secret security clearance, because he drove into a facility where, for operational reasons, all people, including all service people, needed that clearance, or higher, to actually leave the roadway. I was getting training next to a building that, officially, and on all local maps, and many international ones, did not exist, and which was only available off Keyhole and Corona datasets.
A few years later looked on Google Earth, and the satellite view of my office was at sub 10cm resolution, and you could read number plates off the vehicles, a good number of them I had driven. Leave the complex boundaries and you were back to the 1m regular resolution. Still does not have a street view of it. There was one group of people who had the official task of moving the dummy equipment, located a few hundred meters off of the real thing, and much more visible over the camouflaged areas, to make it appear, on the daily passes of the Keyhole satellites, that there was action, and misdirection, of the actions there. But a bit hard to hide the Borg cube that was the one facility. Must have been fun to demolish, but it was.

Any area subjected to stress will have had the paint and other coatings either cracked, or torn, to expose bare metal. and this will corrode fast, not only because it is exposed but also because the stress of deforming it has changed the material structure. Thus this will corrode faster as well, as it forms an anode compared to the rest of the bare metal, and thus corrodes. The water tank is still in good condition because, like almost all water tanks then, it was made from copper, and probably still has the enamelling inside intact, and the outside paint is still intact mostly.
Last things to disappear, aside from ceramic parts, will be the wiring, with copper protected by tar paper, and also a lead sheath as well.

I saw years ago at a Ford dealership workshop the smallest skinniest mechanic, who was the guy they had who did all the interior under dash stuff. His speciality was clutch pedals, brake pedals and putting in the cable reinforcement kits, as he could get up under the dash and do the job, without needing to remove the front seats. When i did the same job I used a pair of chocks on the back wheel, then put the handbrake off, put the car in third gear, and went in from the passenger side, so I could get my head under, with the driver seat all the way back, and passenger seat all the way forward. Did not want to undo all the trim to get to those 4 seat mounting bolts, especially as the trim was almost guaranteed to loose another clip in the brittle plastic, and they were no longer available new.

PWM signal merely does rough work, high time (pull up resistor to 12V so it runs at full speed when not connected) simply enables the motor drivers, and they in turn are commutated twice per revolution by a hall sensor, to switch the 2 coils, the hall sensor output being sent back out on the tacho line using an open collector driver capable of sinking 1 LSTTL input load, or 10mA roughly, and this is the sum of the loop. PWM needs to be low frequency, under 50Hz, to get smooth speed control. The fan has a starter circuit, that is basically a pulse generated every second or so, that drives the one coil, if there is no tacho pulses detected for a second, which indicated a stalled fan. All done in one 6 pin package, which has all that on a single chip, largest area being the 2 current limited drivers, and catch diodes, and the hall sensor on the one edge of the die.

Well, it would devolve to VFR from 1924, when pretty much the instrumentation was the pilot and his eyes. Would suggest a good upgrade would be to add in a standby compass, standby altimeter and a standby airspeed indicator, as a minimum flight instrument list, that will help in case the ancient Garmin decides to brain fart, as they are well known to do with some combinations of a complex map and some locations. All 3 can be bought used, and simply sent in for a certification, and then the standby compass will just need to be swung with the aircraft in flight ready configuration, to adjust the 8 cardinal point compensation screws.
Memories of 3 hours in the swamp, in the compass bay, acting as the intercom link between my instructor melting in the rear, and the 2 pilots and flight engineer melting in the cockpit. After the 10 full circles to get the newly repaired fluxgate sensor aligned perfectly, the others decided to drive back on the tow tractor, while I elected to stay on board, and fly back with the 3 in front. They still had 3 hours of fuel left, but only needed an extra hour to complete flight hours for the month, so they did a little trip out to sea, and there I got to see them doing an aerobatics show with the 16 ton helicopter, doing all the daring moves, that are limited to 0G to +3G, that are permitted with a helicopter when you want to avoid chopping your own tail off, or having the main rotors separate. Sitting in the door, hand through the strap, and looking up at the ocean above me, and the sky past my feet, as they did a few barrel rolls around 1km offshore, with the closest place to swim to being the offshore oil platform. 2 very happy and now cool pilots.

@domehammer Bakery sliced bread is generally a week old when you get it, it is made, frozen then sliced, then kept frozen till it gets in the delivery truck, where there is a heater and humidifier to defrost it, and deliver it hot and moist. then it sits on the store shelf for 5 days before it is thrown away. There are enough preservatives, but the thing is the flour is both bleached and free of any protien, so it does not go rancid.
Making bread at home from a non white flour ( otherwise you just get the same dead flour) and there is a definite taste difference. the sliced bread needs preservatives and moisture controllers, because otherwise it turns to cardboard fast, and gets full of mould. Try using some stone ground whole wheat flour and make your own bread, it tastes totally different, and you will find store bought bread flat and bland forever more.

Yes, and the 70 plus reading is probably from a failed pressure transducer that lost a bond wire off the MEMS sensor, giving a more than full scale high output, which the ECM interprets as over 70PSI, as that is the full scale range it has. Tiny little 3mm by 3mm silicon sensor in there, made from 2 wafers that were bonded together under high vacuum and heat, and with the middle having a small cavity etched in the silicon, and on top a set of diffused strain gauges that measure the flex of the silicon, plus a diode that is used to compensate for temperature.
Absolute, so the cavity is a vacuum, otherwise the ones meant for gauge pressure have the bottom silicon wafer have a hole etched through to allow connection to the other side of the thin diaphragm, and these then get bonded to a reference port. Yes a fab that costs billions of dollars to build, and almost as much to operate, but the sensors coming out are in the cents price each, due to the massive volumes made. Make the sensor a little larger and you can integrate the entire electronic system on it as well, and by making the membrane thinner you make a MEMS microphone, that can be placed in a phone, and give you a complete microphone and conversion electronics, giving direct to digital output, only needing 3 connections to the outside, and capable of handling from a whisper to a scream.

Going to bet though the bridge report went through from Penndot to the local municipality, where it was promptly filed and forgotten. Who owns the bridge, and who is responsible for the maintenance, now that is the problem, because I can bet you these are two totally separate deparments in government, and each tries to pass the buck. But as to failure, yes likely bus was the final straw, though the bridge by that point likely was barely able to withstand it's own static mass, and the bus and cars, along with a few tons of snow and frozen slush, did finally cause the one support to buckle at the base. Then the other side got a step loading, and promptly sheered off, and the other side followed.
I would say the far side from the bus was the one that collapsed, after the bus went over, and the buckled deck is indicative of the supports by the bus holding on a second or so as the bridge fell behind the bus, pulling them over, and then the roadway longitudinal members there, probably from years of salt corrosion removing most of the metal, folded, and the deck buckled at that stress point. The supports pulled off the base, leaving the plate behind, simply because the rusted bolts were stronger, and had more cross section, than the remaining support steel at the time.
Coreten steel is amazing, but really does benefit from having a protective coating applied, just that you can do construction with minimal care, and only lightly blast the surface, or wire brush it, before you paint it, the rust will provide adhesion for the paint.

C J B Don't worry, there are plenty of airports like this in all countries, especially where there are commercial pressures to just move the planes, and fix the issues "soon soon", which gets pushed back always to "next year", followed by "it has worked till now, so why fix it even if it is broken", with the accident always seeming to come as a surprise, and always "totally unforeseen", with the report coming out pointing to this having existed, and having been written up, with no results, for years before, in a lot of cases.

How about coffee bags, which is ground coffee in a tea bag, which you brew in a tea pot, exactly the same as tea, or in the actual cup itself, like a tea bag, removing when at the desired strength, and enjoying the brew as you like.
Me, I drink instant coffee, and yes there are some brands that are better used as brown colour for dirt, but there are a lot of instant coffee blends on the market. Filter yes if I am out, but for what you get at the price, it is not always worth it. I go past the overpriced green logo coffee place to the shop behind them, which serves to my taste a better brew, and at the same time I can indulge in my fast food meal, a chicken salad with hot sauce, and peri peri chicken livers. Place the order and 2 cups, first for while I wait, and second for the walk home.

@ZirothTech not really a new thing, just a standard synchronous motor with external excitation, using a planar transformer to power the rotor winding. Pretty much something common on high power generators, where they need to run long periods without stopping, making them useful in power generation for long run time, as the only thing you need to change is the oil bath oil in the bearings, and thus can run them for 10 years with no stopping, before stopping to clean and inspect them.
Does not even need much in the way of electronics in the power transfer, you have a rotor coil with a bridge rectifier, and a exciter coil with some form of AC power, either simple H bridge at some fixed frequency, giving a constant current, or variable to allow you to vary current based on duty cycle of the bridge, allowing max field strength at low RPM with high current, and at high RPM you drop excitation to a lower level, or even turn it off, to allow the rotor to act like an induction motor, using the diode bridge to handle the freewheeling current, which will improve efficiency a lot, as now at speed no cogging losses in the magnetic system, while at low speed you get a very high breakaway torque. Much cheaper to make yes, and while you have a lot of copper in the rotor, and need to cool it as well to keep the heat down, it will work well, even with existing drives, with only minor changes to provide the excitation power, and the added temperature sensing needed. Your bridge rectifier will probably be improved by adding in active switches, as you otherwise will need beefy schottky diodes on a heat spreader to handle the high current, as high current is needed to get a strong field, and you will definitely want to reduce inductance. So schottky diodes rated around 100A per diode, or add in power mosfets, and a separate power winding to allow an active rectifier to be on the rotor as well. Slightly more complex, but allows an extra percent or two lower losses.

@lbochtler Yes the older type tubes had issues with slow response to bright light, as the phosphor got saturated. Backlighting, and then using a black level clamp to restore the video level back to black, removing the offset at the expense of dynamic range, did help a lot. Of course in TV studio use they simply blocked the iris way down, then put in a lot of light ( 10kW plus on a set was minimum, some went as high as 20kW for what was essentially a 2 desk wide area), so as to both have backlighting on the tube, and also limit peak white, so you could expand video level to a point below smearing, but still have a fast response with minimal smear.
Using for CCTV you had more problems, but there again auto iris was welcomed, or manual iris and accept muddy video.

In floor ones also come with a cam and spring, because they are almost always dual action, able to open either way. Made so you do not need a left and right one for double doors, only a single box buried in the floor, and the closer screwed to it. They do have speed adjustment for each side separately, so you can adjust them to be one direction only by screwing the other side valve all the way in, so it will not allow flow. they are also able to handle much heavier doors as well, and last for decades. Most common make by me is dormer, known to last a half century in use. They can also be rebuilt as well, as dormer does have kits of spare parts for them as well. you do need however to demount the door to do so, which means you need to pick up a very heavy door off the lower pivot after you unscrew the lever that retracts the top pivot. Or in the case of the one side, cut through the pivot on top first, as the adjuster had rusted solid in the 50 years of being there, so I got the 2 new complete units, and the one door was a breeze, just needed Rockset 5 minute cement to fit the new box in the old one, but the other one needed 2 days of work to get the door hardware off, and the new hardware on. Lots of 5 minute epoxy and wood to fill holes from old screws, and then grind the new socket to fit the pin, and same for in the frame.

@danl6634 I installed an inrush limiter on a 7.5kW motor, because the original installer connected the DOL starter incorrectly, and it was starting in delta, then switching to star. Then dropped a phase in the one contactor due to arcing or dust. I replaced the lot, plus put it all, along with the 7.5kW soft start unit, into a dust proof cabinet, and set run up time to 30 seconds. Solved the issue of the unit tearing itself out of the floor bolts. Of course the biggest issue was to remove that 130kg cast steel frame motor from the gearbox, where the shaft was kind of not willing to separate, even hanging the entire motor mass off it. Had to use a BFH and crowbars, and the trolley I had under it suffered badly. New one was light, only 78kg, so easy to lift up with the chain block, and that shaft was well greased.

@danielstickney2400 Or that the factory would take all the castings for the previous day, and place them in a furnace that had been used, and allowed them to heat up from the residual heat in the lining, and slowly cool overnight. That way any that cracked could be told using a ring test, and tossed into the pile for the next melt, and any that were too badly warped as well, while those that passed went into the machining shop to get cut into shape, most likely on a shaper as well, and then finally ground to final dimensions. 3 shapers , each with a jig, could do all the rough operations and not worry too much about hard spots, as the HSS cutter will only wear slowly, while a single operator for 3 machines will be able to keep up with the needs to swap tooling, and parts from jig to jig.

Power supply capacitors aging, and the top section of the picture there was insufficient beam current in the EHT circuit to provide a bright image. The picture started lower down as the scan current reduced as the scan got to the middle, and the lower half the scan coil, while still having an increasing current, this was stored energy in the coil being dissipated before the high energy pulse rerquired to do the retrace to the top again. The CRT is blanked during flyback in both vertical and horizontal, so the blanking interval was increasing as the set aged, and your particular set design used the vertical deflection circuit as the source of the vertical blanking signal.
Other designs used a digital counter in the jungle chip to do this, you would have had a smeared image with the slow flyback instead, though generally the later chipsets also sensed beam current, and would shut off the horizontal and vertical drive to the CRT if the current varied beyond acceptable parameters, done by sending a specific set of pulses during the top overscan in sequence to get the dark current, a mid scale current and a full bright current, and storing to allow to compensate for tube aging. If you deliberately made the raster fit the CRT instead of being overscanned you would see a set of 3 red green and blue strips on the top 6 lines, with there being none on the left, then either 3 or 6 lines, one dark and one bright of each colour. This then set the black level clamp of each gun and the peak colour drive of each one instead of having to adjust them during service, so the hue did not change as the CRT aged.

Could be that, but a lot more likely to be environmental factors as well, that added to the dosage, plus exposure to chemicals, that inhibited the cell repair mechanisms, that were the cause. Live at high altitude, increased radiation from space, live by rocks emitting large amounts of Radon, increased risk. Live by large industrial processes, that dumped fine particulate matter in the air (coal, steel, oil refining, open cast mining amongst others) and water, or live down wind of large industrial plants, that emit waste gas and fine particles, some of which are radioactive isotopes, that are either natural or man made.
Safest place to work is in the actual radioactive product industry, where they actively track down and monitor all sources of radiation. Had that, where the trigger was the road crew coming in, and triggering a monitoring well, as they had used a freshly crushed batch of granite, which had more than a little Uranium and Radon in it. The wash water, that they used to clean the dust off the gravel in the batching yard, before coating with bitumen, was a little above background level when they dumped it in a storm water drain, that was using the soak away the plant used.

They do have the advantage when going offroad, as you are not going to worry about scratching the paint on your expensive 4 by 4, and to fix it you have the entire tool kit in the front, just need to find the nearest fence for wire, or bring some along. Plus you can climb into the engine bay to fix it, no tight spots, just remove the full size spare, the high lift jack and the toolkit and there you can fit in.
Plus they also have a starter handle on them, at least the Lada Niva 4x4 did. the only vehicle that came, new from the factory, with both rust and a any gear will do gearbox. Looks junk, but will outdo a Landie in any respect other than towing ability and top speed, but can climb pretty any slope that you can drive up.

Had that a few times by me, the run a scam in an area for a few weeks, then move to the next suburb after a few marks have paid the money for it. They choose an address, then grab other pictures from another place, and put it in the ad, and run this with a few dozen listings over and over. Sadly had to tell a few people that the place they were wanting to rent does not exist, and that they got scammed, and to go lay a charge at the police, who will just fill in a form, give them a case number, and simply then do nothing, then close it a week later on.

Similar here, aircraft being towed out of the bay it was in. However there was miscommunication, and they did not disconnect the nose wheel steering link pin, so as the tug and the tow bar turned, the nose wheel did not. Frangible link did as intended, and broke, disconnecting the aircraft from the tow bar, and, as it was now on the slight incline out of the bay, it rolled down till it stopped in the reinforced earth berm 10m away. Guy in cockpit was pumping the brakes, but as there was no power, as battery was disconnected and removed, and he had no time to use the hand hydraulic pump either, so it rolled till stopped. Unfortunately the furtherest point forward was the pitot static tube, which pushed back, shearing it's mounting points, and moving back around a meter into the nose. Then the radome tip hit the wall, and penetrated the 3mm steel sheet.
Radome actually survived intact, no damage to it or the rest of the radar cover at all. Unfortunately not so for the pitot probe, and the space behind it, which was the main electrical control box for the aircraft, and the aluminium alloy probe pole sheared through it right in the middle, cutting the main mount that held all the aircraft relays almost in half, relays, wiring and breakers and all.
Damage was repaired in under 2 weeks, because there was another airframe undergoing a full rebuild, and that nose section was completed already in the rebuild, so it was shipped out, and put on in place of the original, which then went to have it's 7 figure rebuild, delaying the other aircraft only by around a month overall, but more than doubling the overhaul cost. That aircraft was odd till it's next major service, having 2 distinct different paint schemes on it front and rear.
There was quite a bit of fall out from that, but luckily I was a spectator, though did get to see all the carnage up close, as the radome came in for inspection, along with the nose of the aircraft landing up outside our service unit doors for a month.

@TechnologyConnections The way those work is to use either the condensing coil fan to sling the water over the condenser coil, or to use a condenser coil below the evaporator coil, so it drips down via gravity and then is channelled over the condenser fins. This then allows the evaporating water to provide extra cooling for the coil, improving efficiency. The big drawback of this is the uncoated coils corrode really fast, and in general only last 3-4 years before they are only a mass of corrosion products on the inside, blocking the air flow, and bare piping that is running hotter than safe ( higher pressure, greater erosion inside the microgrooved pipes, oil breaking down from the high temperature into acid and carbon) and ultimately failing. Outside they look fine, but are totally blocked once you get to the fan chamber.
Window wall units do the same, unless you remove the rubber bung and install the optional drain line, though most of the new ones do not come with a drain, and expect you to replace the entire unit after 4 years, from the case and coils being rotted through. Note the warranty is only 3 years on the compressor only, the rest of the unit is only statutory warranty ( often a year) and in general you find they never get a warranty claim, as if the compressor fails within 25000 hours ( they rarely do, even though they are cost cut way down, but that is another story) that is a rare failure. Coils however are often badly rotted after only a single season if you live near the sea, like I do.
Split units have to have the 2 drains, though often the outdoor unit drain is rarely installed, as in heat pump mode the outside air will be very low humidity anyway in winter. They do build up amazing amounts of sludge and bacteria though unless regularly serviced and cleaned. The inside plastic parts are black, so the sludge mat does not show visibly, even if the rest of the unit is light coloured plastic.

Handles need to be made from hemp rope, unwound from a thick rope so you still have the twist from the original lay, then with hollow hardwood handles with the rope threaded through, and into the side holes, with a similar one for the top. Agree on the modern screws being too good, need to mangle the tops a bit, making the slots varying width,m and hammer the heads to show more aging, using a plank with them screwed in, and then a small ball pein hammer used to round off the edges, make the tops uneven, and then saw the slots with a dull hacksaw to make them irregular, then dip tops in ferric chloride for a hour or two, to etch the heads to a more round shape, losing all sharp edges, like they were carefully hand made centuries ago, and worn down with time.

Yes, did my drivers with a Datsun 680 pick up, with column shift, all 4 speed and reverse on the tree, and with the full Nautilus package, of no power steering and drums all round. Then owned a VW Beetle, same thing, just gearshift on the floor. Currently drive manual as well, simpler to maintain, no trans fluid to get dirty and die, and a clutch is cheap as well.

G overload you tend to pull rivet lines in the skin and internally. There is a set of G counters in the airframe, that increments with each cycle. Low level ones go up by hundreds of cycles each flight, the higher numbers rarely, and if you increment the top counters, other than the same with the test counter, that airframe undergoes inspection, which is a few hundred hours of work to strip it down enough to inspect all structural joints, and measure all critical dimensions. Pull high enough and that airframe will be scrapped totally, even if it flew back with no seeming damage, but all the structural members will be out of allowed tolerance, and your skin will have a lot of pulled rivets, showing up in the wings as weeping rivets in the tanks.

Yes a much better option over a 100A relay, that will both not be rated for full time operating, and also as they normally come with always being able to remove the key in the off position, it is easy to see when the key is in use, and also have a convenient way to disable the system when not in use. Though if you are putting in the deep cycle batteries a much better option is to get a dual charge controller, and leave them always in circuit and charging when the truck is running, so you will both never have them not get a charge, but also they cannot discharge through the truck itself if the main battery is flat for some reason. 150A dual charge controller, that attaches in the lead out of the alternator, and gives 2 heavy duty feeds, one per battery, will work much better, and less problems. Will still be a good idea to have a disconnect switch there though, inside the box, just in case, and also a 120A fuse in the battery lead for protection. Car audio can supply all these parts, just beware of the cheap ones with CCA wire leads.

By me all vehicles sold after 2012 have to have a datadot marking on them as well, which gives thousands of serialised microdot tags that are glued all over the chassis of the vehicle, including on the door panels, inside and under linings, and all over the underside. As they are held down with a good spray adhesive, and glow under UV light, a single one registered to a stolen vehicle is enough to mark the vehicle as suspect.
Toyota since 2012 has been placing VIN stickers on every panel during assembly, many before the actual painting process, and many also inside welded sections, so they are hidden there, but are easy to find if required. Then after the shell exits the paint shop more are attached, so that every panel of the vehicle will have a sticker, near impossible to remove, that records both the VIN and manufacturing information, both in numbers and machine readable format. Used down the line to customise the vehicle if needed, so that you can run different models in a row, and have the assembly line machines and people simply pick the right parts to place per vehicle. Different trims simply by the trim coming in on a robot to the place, all ready to go in the vehicle, exactly as needed. Over 100 labels start with the panels, and all will be placed along the line, leaving only a carrier sheet behind, all labels being laser etched, so that the marking is near indelible, and hard to damage.

Easy to do, they steal them, drive to a rented industrial lot, and stack them up to 4 up in the container, then ship them out with a forged export permit, either saying it is scrap metal, or by hiding the vehicle under scrap metal. Then when they arrive in Nigeria, or any of the West African ports, they get taken out of the container, and either then get falsely entered as vehicles into the systems there, or are smuggled across the border to another country, where you can get papers using just a bribe, then they take them, with the "legit" papers, and export them to other countries.
The container cost is low, as the ships are deadheading back to China, so a hundred containers to Africa, even if you have to send 20% empty or with a part load of ewaste in them, and stolen cars the rest, will be cheap, and the ewaste will pay for the shipping, leaving the rest of the money from stolen cars as pure profit. Might be $500 to ship the container, including $500 for the buying of a scrap container, which will probably be resold as either a house, or a container to be filled and taken with scrap to China later on. The vehicles will be bought from the thieves perhaps for $1000 at most, for top of the line new ones, or anything from $200 up for common cars. Sell for the equivalent of $5000, including the washed papers, and they will be run till they fall apart, and can no longer be blacksmithed back together, then stripped for scrap metal, and spares for other vehicles. Half the stolen cars, common ones, will be chopped up before the container, to fit 20 engines and front halves into the container, and sold as running front halves, to be used as spare parts, or used to run equipment and farms.

@taoliu3949 Yes and flipping the breaker disdables the alarm, especially if the alarm has already reported and been validated the alarm has been acted on, it will not send it again. 100% the janitor was tired of the noise, so went to the panel shown to be the controlling one (being a university likely the plugs actually are labelled, and say which panel controls them, and this is actually correct) and turned off the power, and left it off. Did not turn it on thinking the power had tripped, he definitely turned all off to shut the alarm up. Now the person and company is on the hook ,and the bill will just get larger and larger as all the funders for the experiments lost add in to the claim.
Yes they should have had 2 fridges, yes they should have had backup power, but the board likely is one already on backup power, so he turned off all redundant power sources.

Yes exactly that, granite floor tile (not reconstituted quartz stone, but the real cut out of a mountain slab, and checked for it being optically flat) on a plywood base, and it works for me as a good enough for the stuff I do block. Got a second one just in case, that is still not used, but there are 2 granite offcuts, counter top reconstituted stone, that I use for a mouse pad. Big, heavy, works well with optical mice, and does not move, plus easy to clean. A third gravestone offcut, mostly polished before it cracked, got repurposed, along with a dial indicator stand I got cheap, as a microscope stand. Reminds me of the optical test benches, which used a massive granite block beam for the frame, for rigidity and temperature stability.

@helplmchoking The one who has a clue, but needs a clue by four applied to him. To be fair, those kind of electrical gremlins are often hard to find, especially on a machine that is at best described as newish to you. did spend one December fixing up an old packing machine, and getting it to match the manufacturers blueprints again for electrical. Real blueprints, and with a good number of the parts being made from Obsoletium in the electrical section, but was able to replace them with plug in industrial standard building block parts.
Amongst all that also did the mechanical side, replacing a lot of the smaller bearings in there, along with a lot of cam followers. Those are expensive, especially when you go in and order them by the dozen. Then some linear bearings, and the steel rods they ran on, because the old ones had worn grooves in the steel. Got it down to only one Festo cylinder, replacing all the others with SMC, but that one was only available from Festo, and a pretty price.
All pneumatics changed out, with the exception of 2 Numatics valve bodies, they got friends instead, as those had been in there since at least 1986, and even though I put a service kit in them, they actually did not need it, but the kit was ordered anyway, and was cheap. All went Numatics, they had proven themselves, and worked out costing less than Festo, especially after a year, which was the life of some of the valves, which refused to fail.
got around 20kg of crap out, old changes over the decades, and replaced a lot of quick fixes as well, seeing as I was able to access the rear of the electrical panel, so put the bodge wires in there instead, and pulled the failed wires out as well. A dozen or so 8 pin and 11 pin bases to replace failed timers, and failed Brown Boveri relays, and then some work to replace the cursed Diazed fuse blocks with breakers, forever keeping me from needing to buy those fuses.
Biggest change was an inverter, replacing the old Varispeed drive, as that was worn out, though, because of the gearbox, the drive belt stayed, I simply took the variable side off, and put in a double V belt pulley and Fenner lock block, with the pulley having the centre turned off it, to make it fit the varispeed belt. Main gearbox stripped, new bearings and seals, and filled with oil, instead of the NGLI0 grease it had, which was now nearly solid. Noise solved with molyslip. New clutch linings, fan on the drive motor as it was now going to run at 30Hz, so forced cooling was better, and the original 1970's era Lenze motor was still in great condition.
That was one busy 3 week job, but the machine was running like new. Obsolete, but a replacement was nearly a million Euro, and the old machines are still in use around the world, simply because they work, though the Chinese copies are a tenth the price, and do about 50% of the capacity. OK they come as a ready assembled kit, and you really want to strip them down, and rebuild them off the bat, to at least get the dirt out, but they do work well. Bought Chinese instead of fixing the other, simply because one part quoted more than the price of the new machine, as a service exchange part, with a 3 month turn around time. It became the back up machine, though in 10 years we actually did not use it at all.

Most of those seals push in, so you remove the casting and press the old ones out, and the new one in. I would say that the cams are assembled using a jig that holds them all in alignment, and the cams and head are heated up to around 150C in an oven, while the shaft is in a liquid nitrogen or dry ice chamber, and then the shaft is aligned with the top casting and pressed into position fast, so that the cams shrink onto the shaft. Not easy to fix, but saves a lot of weight, in not needing any bolts in the upper head, and no chance for misalignment while boring out the bearing holes, though you will need to have very precise control of clearances.

Not as critical, as the interference pattern causes a large variation in return light, but any pit approaching the required depth causes some interference, and the return light is less. The receiver in the player is not too concerned about the actual variation, just that, relative to the transmitted light returned from the smooth surface, there is some loss, and that this is enough for the player to discern the pits from the lands. There is a variable gain stage that compensates for the variation in return before the data slicer in the laser electronics turns this very analogue voltage into a digital signal for further processing. This analogue voltage is also filtered and forms part of the focus, as it tracks the average distance between the laser focus lens and the actual data layer on the disk, and the lens is kept a constant distance despite the actual disk having variability of up to 2mm per rotation in use.
Then there is the fact the receiver is actually 4 separate photodiodes in a quadrant, so the signal is the sum of all of them, but the difference between opposite pairs of the diodes is used as info for the focus system and the 2 linear tracking servo loops that keep the laser beam following the single long spiral track faithfully, despite it not always being concentric in the disk itself.
Incidentally almost all the laser modules were developed by Sony, and you find a whole range of KSSxxx laser modules used in CD and DVD players, all operating on pretty much the same principles, but with various layouts and mounting methods used in them for various players. Now almost an industry standard module, often no longer made by Sony, but still with the KSS part number.

When I was younger we had a similar tree cut. Dropped in the only place it could go, right on top of my mother's rambling rose, making it flat. To the right in the pool, to the left it would bounce into the neighbours property off a bank. After it was cut up we did have fire wood for around 3 years, though we were fighting with the termites for the wood near the end of this time.
Friend also had a similar tree, he hired a tree feller, who dropped that tree in 1m sections, making a big hole in the rock hard ground, as each part came down from height, and as he came down those 1m sections got heavier and heavier, till he had to use the crane on the truck for the last 10m of trunk, as 4 people could not lift them. one went the wrong way, but the bougainvillea hedge bounced it back into roughly the right spot. We trimmed that hedge 6 months later, using a chainsaw, and found there was actually a fence, and a gate, there in the middle of this hedge, which had not been trimmed for at least 20 years. Chainsaw and 2 weekends work was cheaper than what the garden services quoted to cut it, though they were quite happy to remove the 5 truck loads of hedge afterwards. We understood why after starting, though I have done those again. Extension chainsaw works well there, you are at least a way from those lethal thorns and the spring on cutting a branch.

Yes, and the clock is a nice branded one, from the bolt supplier, so not only a good show of the amount of time, with no wasted work, and a good bit of product placement as well for the supplier, who will always have customers coming in new, having seen the brand on the side, and choosing them when looking for fasteners. Plus good bolts, all of them looking nice and new, though in a year all will be back and need to be cut off, at least those that are not simply ripped right out.

Same for washing machines, I live in a soft water area, so use a quarter of the "manufacturer recommended" dose, and it works well, with no residue, and no floating growth in the machine either. Also not connected to hot water, and the generic Unilever store brand detergent as well, because, shockingly, the biggest difference between brands is the scent package, and the amount of brighteners added, along with possibly a slightly different amount of borax as filler.

Not mandatory here in South Africa, but many of the new units come with this by default, as the units are imported and thus they comply with the big US market safety and ancillary wise. Older units do not have anything other than chimes, and some that are from the 19th century are still in use, just having to have safety upgrades ( door glass with safety glass instead of window glass, inner doors instead of the lattice steel, an emergency light and bell in the car) to comply. The new ones are almost always, in a retrofit or as a lower cost add on to existing structure, a motor room less one, and the hydraulic powered elevator is almost unheard of here aside from in some very old, no longer approved for passenger travel, goods hoists that have no in car controls or lighting. Even a goods hoist new has to comply with passenger car regulations.
When you upgrade an older unit ( controller and car interior upgrade, replacing only the inner skin, the floor and the lighting, plus the call panel and trailing cables, along with a new controller driving the existing motor and gearbox, sheave and cabling and shaftwork) you typically get the audible signals and direction signs as part of the package, though they might not be installed in some buildings due to lack of space and no wall boxes.
Your building I would speak to the elevator service company, and they can plug the modules back in to the controller, and simply unscrew each panel and use the volume control built in there to drop the volume down to quiet. Suggest to the building owner that the penalties for non compliance with the ADA are pretty high, and deliberate non compliance can result in multiple lawsuits against them in person.

You used the wrong defence. You needed to prove your vehicle was in that other city at the time, either with a toll ticket, or a parking bay ticket that had registration attached, or a expense report that you used your vehicle for the trip, and were with the vehicle in that city at the time of the alleged offense.
I got tickets for tolls, and cloned plates are such a common thing that the ticket also has on it "if you are disputing due to cloning, here is the web link", and this leads you to a page, where among the options is a form you download, fill in and have witnessed at a police station, that this was not your vehicle. Did that, went to post office, got it witnessed, and scanned and emailed back. Never heard of it again.

@ExplainingComputers Yes POE is becoming very common as homes get IP cameras and such installed, which all then only need a single cable run to the device. While IP camera prices are dropping, you still find it common to have cameras that use coax cable, though there you also have use of UTP cable as well and a balun at each end, so 2/3 pairs are used for power to the camera, and one pair is used for video back, allowing you to have 2 cameras at a single point, and only run one low cost cable. There I have often used CCA wire, as the cable is very cheap, not that great for flexibility, but as it will be installed once, and left alone, cheap in that you can run 2 or 3 to all locations for future expansion, as the hardware is upgradable, and the biggest cost of installing them is laying the cable, not the actual cable itself. I have used entire boxes for a 4 camera install in a small house, just having those spare cables tucked up out of sight meant the future upgrade to 8 or 16 cameras was very low cost to do.

SLA batteries the amp hour rating is determined at a specific set of conditions. They charge it and see the capacity, say 9Ah. Then discharge it at a rate that it will take 10 hours to discharge, so around 1A for that battery, a C/10 rate of discharge. However discharging at a higher current the amount of energy you get out before the low voltage cut off is lower, so it will likely, at around C current draw, only show 6.5Ah capacity, and conversely, at C/100 it might run for giving an apparent capacity of 11Ah capacity.
I took a 20Ah SLA pack, known to be poor, but still delivering 13.8V at 100% SOC, and loaded it down with a 3s white LED string, that drew 100mA initially, and left it to go. After 5 days it was now down to 11V, theoretically fully discharged, but still was able to light the LED string with 5mA, and after a further 2 days it was at 9V, and the LED string was still glowing, albeit dimly, and you could see the individual dies in the yellow phosphor coat. Another 2 weeks and it was still glowing enough to cast a shadow at night.

My father travelled it a few times in Japan, and, due to an earthquake, the train was delayed by 15 minutes. There was a station master at the next station apologising for the delay, as it was a major delay, and he was very unhappy about the ground daring to mess with his schedule.
My dad did however still get to his destination on time, to tick an item off his bucket list, to see all of the Soviet Union, as he had, during the war, seen the west side, travelled to Asia and seen the middle, but the far east side was still something he wanted to touch foot on. so he tot to travel to Vladivostok, and walk on the runway, as a part of a JAL crew there for a flight, just never leave the airport.

No need to actually look for a new processor, simply use one of the more modern Space rated products that are still available in large volumes. Intel still does supply the 386SX and DX in space rated packages, using a SOS technology, which is a more modern and faster part. Yes likely just a few thousand fully tested dies in CA storage, ready to be packed and tested to order, but still a part likely to be around for the next 50 years.
Buying an original Mostek or Rockwell part is still there, not robbing old equipment, you just pay Rochester Electronics to take a wafer and pack it, then test the result and get the qualification, they specialise in old silicon, buying up old wafer stock and storing them essentially forever. You need it you pay the price they ask, and smile. With gritted teeth, they price just below replacing the whole lot entirely, but still cheaper.
However the 6502 is, thanks to it being out of copyright, one of the more prolific processors around, available as an IP core for pretty much all FPGA and ASIC families, as it is simple, very small and very functional. You have one in every hard drive, used to load the firmware into the ASIC and FPGA units that do the actual work, and it also then is a slow processor, but tiny one, that does housekeeping and monitoring of the hard drive, so that the drive can retract heads and shut down gracefully when power is removed. With only 64k of memory you can make half the fixed ROM, for bootloading the rest, and the rest RAM to handle memory, with a little bit of IO somewhere to feed data out to the rest of the array. Simple to implement in silicon, free assemblers and compilers, and no money to pay for a per unit license, it is very common to have it embedded all over in equipment as a processor doing something.

Well, you have now met the French design philosophy, make it easy to assemble in the plant, when it comes as a complete assembly, and you simply bolt it in place. They put the rotor there to get it inboard a little, and leave space for a thinner rim with less offset, so it can be lighter, as there is more even loading off the sidewalls, but did not consider that you would need to change rotors outside of the warranty period. Figured pads would be changed every 2 years, and the rotor would not be worn below minimum spec before end of warranty. Who cares if it got grooves or warped, so long as it was outside warranty, more money for the dealership to make off book rate.
The studs are simply using the existing holes for the threaded bolts, as they figured the US market cannot use a bolt into a wheel, too much training needed. So went for the stud instead, simply changing the tooling used on the CNC mill to a drill size for the stud, instead of a clearance hole for a tap, and then a spiral machine tap making the thread. One extra assembly step for the OEM, to put 5 studs into the unit, and press them into position, and on the assembly line just give them the 5 nuts, instead of the regular bolts.

Buy used, let the first owner take that 50% depreciation hit on it, and all the teething problems. Also never buy the first year of any new model, wait till they have 3 or so years of production to find out all those little issues, like blowing transfer cases, grenading engines and electrical system failures. Look at VW, they made the VW Beetle for 50 years, and the VW Golf/Rabbit for over 30, and both are pretty reliable robust vehicles now, with plenty of after market support. Same for the Toyota models, the older long running ones are reliable, same for pretty all automakers.

@heartobefelt Pretty much all run on 400V 3 phase power, 50Hz or 60Hz not an issue, as the motors are rated for both frequencies, and run at either 1440 or 1760RPM in each case, which still means they are capable of handling the load. Ship power systems are pretty much capable of running on 50 or 60Hz with no issue, all just are 3 phase with neutral, and the ship has transformers to handle the input voltage, and supply the appropriate voltages. Bigger ships have high voltage systems to distribute, up to 6600V, but most shipside power is 3 phase 400VAC, which is a normalised voltage, but can vary from 380V to 440V between phases and still comply.

747 INS was based on taking the closest 2 out of 3 separate systems. Each system used 6 small peanut gyro units, which are smaller than a fist each, in a redundant system, one per axis, to keep the inertial platform level, at the start position when powered on. It would turn 360 degrees almost in a day, the error being the amount the earth rotated along it's orbit, and if you left it running for a month you would be able to extract, from the residual noise, the orbit of the sun around the galaxy as a small constant offset. On this platform are the 3 accelarometers, which then get integrated to give you velocity, as a 3 vector output, and this then is integrated again to give you distance again as a vector output. Mapped by the computer on the IMU to a model of the earth, with known starting position as a point, accurate down to the foot, measured by the nose wheel being parked on a painted spot on the hardstand, and the body aligned to a line as well.
They are accurate enough to fly waypoints to within a few feet half way around the planet, and to get you within a hundred foot of landing on autopilot. Replaced by the laser ring gyro units, which can do the same, but the drift is so much lower that you can let the autopilot fly till touchdown, with no worry that a gyro failure will get you out more than a few feet. Plus no more temperamental units as they aged, where you might find one of the dual redundant halves fail in flight every few thousand hours, and you would have a slight degradation in accuracy overall, but only see it when you landed and maintenance looked in the bay to see the one unit is showing a degraded accuracy flag on it.
You need a class 10 clean room facility to repair them, not many of them left around who still have the room, the tools, and most importantly the skilled technicians to work on the units any more. I was lucky to get the tour of SAA Technical in the 1990's, as part of training, where as a group we spent a day in there, in the class 10000 clean room facility looking at all the work they did. Look into the clean area to see them strip them to bare bones, pulling the peanut size gyro units out of the housings to service and calibrate them.

@eno2870 That would be extra, as you then have to use medical grade oxygen, which has a much lower concentration of contaminants, most notable being nitrogen, which is pretty close in boiling point, so you have to do fractional distillation of the liquid, or use molecular filters to reduce the volume of contaminants. Expensive and slow, as you do need to keep a very precise control on the pressures and temperatures.
For each passenger you would need around 3l of liquid oxygen, per flight, and probably around 15l of liquid nitrogen as well, so as to be able to make a one atmosphere environment, and simply dump all the exhaust out of the craft. Otherwise you need lithium hydroxide CO2 scrubbers to be able to recirculate the air, and then your gas needs are lower, but you do need a lot more mass in scrubbers. However the scrubbers need to be fed dry air, so you then need to extract almost all of the humidity out of the air first. So, probably a ton of scrubbers alone, another 2 tons of airconditioners, for the hundred passengers, to save the 1500kg of liquid nitrogen, but the LOX is not going to be much less.
That assumes you want to have the passengers feel like they are in an aircraft, though you could get away with dropping cabin pressure to a bit lower, and increasing oxygen concentration, but having them need to spend an hour before and after each flight doing a decompression would probably not be a desired thing. After all, the space shuttle and ISS takes the best part of a day to get ready for EVA, because the low pressure in the space suits requires all nitrogen to be removed, and the time for the Starship will not be much less.

In flight they sit in a nice insulated wheel well, surrounded by a really thick layer of insulating rubber from the tyres. They only really cool off when exposed to airflow in the time the wheels are down and the aircraft is taking off, and on final approach. When in the air stream there will be flow through the pack, but typically only the outside, as they tend to be touching all the time, held there by a set of springs so that the hydraulic system has a consistent volume of liquid it has to pump for a specific brake action.
Inner sections will stay hot for hours, especially in hard braking, and having a RTO also means you have to have a brake inspection and probably replacement, as you likely lost more than half of the active material scrubbing off that energy. You will also likely need tyres as well, they will have had a lot scrubbed off them, even with ABS, as there will still be a bit of slip as the valves modulate grip.
The original friction material up to the 1970's was asbestos, and it is still used in some niche applications, as there is nothing that is drop in. But the modern ones use a ceramic material, or carbon composite, as the friction liner. Thus temperature monitoring, though the bigger issue is tyre degradation from heat, which is why they have a fusible plug on them that will deflate in a controlled manner, rather than exploding.

What about you send it to the manufacturer, and they have farmed it out to some service centre in Mumbai, because it saved them 30c per hour on the repairs, irrespective that it now takes 6 weeks to get there and back, and often the service centre is just using somebody off the street, hired that day, to fix it, with no manuals, instructions or spare parts.
Or you have spent $1 million on buying equipment, and a year and 2 months later you are told that it is discontinued, no longer supported, and that you need to buy the new one, at $2 million, which will also be out of support in 10 months. As well you find out you need to retrain all your staff on how it works, at your cost, in their facility in BFburg, for 3 months in order to use it. New stuff is the same as the old, just they changed colour of a screen and cover, and changed a critical connector so your old per patient spares no longer work.

You need to get the updated machine, which has the slides you use that also embosses the value directly on the bottom of the self carboning triplicate, so the bank can use the same OCR machinery that they use for cheques to read both the card info, merchant info and the amount off in a single pass, without needing to have any person do data entry.
Does it have the brass embossed shop details still, or the later cheap embossed plastic tag as they were phased out, and relegated to backup for a regular card reader attached to a phone line.
Got 2 of those, which were replaced by the bank as they upgraded systems to enable EMV transactions, and those in turn were superceded and replaced with ones that can do contactless as well. But all still have the old fallback of magstripe read, and when that fails you also can use manual card number entry, though you also need a supervisor PIN entry per transaction to do so. Even pizza places now have gone away from that, you either order via app, or pay cash on delivery, or the drivers come there with either a portable terminal, or use a regular mobile phone to do the contactless pay. No merchant (aside from the Post office, still stuck using XP, and the same computers they bought in 2000) does magstripe only.

Definitely hinders, because every cent you "save" on feeding poor food, or packing in more prisoners per day, is extra profit. So food is the cheapest slop they can give that meets the minimum definition of "food", in minimal amounts, and as many bodies as they can fit inside, along with spending as little as possible on staff, facilities and maintenance, as all those detract from the income. So food is all bought as surplus, or lowest grade, and cooked and served in minimal quantity, and the last time the place saw paint or any sort of maintenance was when built. Light bulbs are replaced when they all burn out, so it is common to have cells with no light at all, and as the fittings are vandal proof, the replacement will only be done when they can get all the wing into another wing for a day, then get the cheapest contractor in, to do the shoddiest job, using the cheapest bulbs, so they fail again often before they are out. Toilets and showers will stay broken, till they get told to fix it by the overseeing government department at an inspection, and somebody forgot to hide all the buckets in the cells.

With 11 official languages, and a lot of words that mean one thing in english, but are also a very offensive term in another, there is a lot of fun here. You can say cake, which can be, in another language, a derogatory term, and the USA will not know better. there probably are a few dozen ex SA people in the USA with very derogatory plates, simply because the US does not realise that.
The Hungarian for cheeseburger is also used to refer to certain body parts, especially when less than sanitary. and yes there is a local person by me who has the vanity plate of snake, as he is also on Discovery channel. He is very busy this time of year, seeing as it is now snake season, and they pop up all over. They are only 20 minute snakes, not too deadly, as you have 20 minutes to get to hospital......

@hondaguy9153 ROI will suck with that, and in general most industrial electrolysis plants do not respond well to rapid changes in control, they all will have very bad transient response, and you will not get a good product out efficiently. Extreme case is an aluminium smelter, where the penalties for loss of input power are massive, and can result in the plant needing to demolish large chunks of the equipment and rebuild them. Electrolysing water also needs additives, and filtering out the most common byproduct, chlorine, from the system as well, plus it is also incredibly energy intensive.
Your cost to make from electricity would be more than double than reforming methane or natural gas, or by using syngas from coal in the Fischer–Tropsch plant process. If you have enough biomass on a reliable scale syngas direct would work better to run engines, plus give a food crop as well, though it would probably be best used on the farm itself to run the equipment for modern agriculture over diesel.

Add extra insulation to the water heater tank, plus as well insulate the pipes coming in and out of it as well, at least for the first 6 feet. That way, with care, you will have hot water for 3 days, and warm water for a week. I added 3 layers of insulation to mine, and got that out of it, making the unit so much more efficient, as the standing loss on the common unit is pretty high, because the manufacturers just put enough foam to reach the EPA and energy star guideline, and most installers do not insulate all the water piping like told to do in the manual, because that costs money, and is not included with the new unit either.

You can get a custom LCD made in China, which is a product that has dropped in price, though you might have to reverse engineer it, and order 100 of them, but you can always sell the other 95 to recover the cost, fixing other units that used the same display. But as it is likely a 4 digit common backplane display, and those are still common parts, should be easy to find a modern drop in, though you might have to do a little work to make the pin spacing closer, as the modern displays are considerably narrower, so the pins will all need a spacer.

Yes, they did have a reputation of slop from the beginning, but that would stay the same till it rusted apart. Yes get up and go, got up and went, but there was nothing the Lada could not climb, much to the chagrin of the 4x4 clubs, where the only thing that stopped them was rocks so big even the Land Cruiser was bottoming out, the Lada 4x4 was simply able to idle over all obstacles, and climb almost vertical slopes.
Plus so cheap that you had no worries about damaging it, your Lada was cheaper than repairing the Land Cruiser, and you could just panel beat it back into rough shape, and carry on. Plus the engine bay you could climb in to to work on the engine, and the full size spare, high lift jack, good tool kit and starter handle were standard. OK not the fastest, or the lightest on fuel, but had a really good heater, and AC you opened the window. Still a fair number of them running around, rust in close formation.

Available commercially as a DALIK plating kit, which you need to have a better electrode to use, with a larger surface area, plus a continuous flow of weak acid, to provide a conductive path, and get good contact with the cotton swab. Make the battery case flat, and try again, with a cotton swab well soaked in a dilute phosphoric acid solution, basically that bottle with 3 times the volume of water, soaking it to be wet and not damp, and only a single thickness or two of cotton cloth, old well worn denim works there, to act as insulator and carrier. Wet the metal surface as well, so it does not dry out, and thus makes for even plating.

@jeffostroff No, the penthouse unit on the 55th floor, in flat 386290, with my entire irreplaceable stamp collection, priceless artworks. My car collection of 80 Bentley's, 15 Ferrari's, 200 Mclaren F1's and also my private boat, all in my garage bay. Also had all three arms broken, all 5 feet amputated, and thus cannot attend in person, so am sending my representative "Bob" in my stead, with a letter from my doctor, the Rev Hon Dr Mr Prof Sir IR Cheatam Esq.

Most modern engines the tolerances are so close that there is minimal extra care needed to run the engine in. See your average Toyota, where the first service is not at 1000km, but at 15 000km, and then again at multiples of that, and they do not generally blow up engines on the first day, even those that are run "enthusiastically"by the delivery drivers.
Modern tolerances and assembly means that the sort bins used during assembly are so close that you just pull the parts out of the right colour coded bins along the line, for the critical parts, and put them in, and the engine works perfectly, and also most are tested on the line during assembly by a computer that turns it over, measuring dynamic parameters, like oil pressure per degree or revolution, and torque to turn, and can detect of the next size bearing shell was put in the crank on one position.
Must have been a Friday afternoon engine, just before quitting time.

There is no audio in that application, just video, and often just mono video as well, as this needed less memory. Most switchers used a 2k RAM chip and a video flash ADC to sample the video, using 4 sample and holds to drive the ADC, and using the sync signal to determine where in the RAM to do the write. Output was a simple scan of the entire RAM to a DAC to generate video. The one I have somewhere used a Z80 and a 6116 SRAM for memory, with the control program being in a 2716 EPROM, plus the flash converter and a quad SH chip, along with some simple sync detection. Unused inputs would be set to a blank screen, and it could either do 2 or 4 on a single output, or switch in sequence, genlocking the output so the TV would not twitch during the switching.

Worst pain is the heater core, followed by the blend doors, because the entire dash has to come out. While you are there might as well also replace AC evaporator and fan motor, because by now both are pretty close to knackered. While core is cheap, along with the blend door foam, the labour to change them is not, and you run the risk of breaking any one of hundreds of little plastic clips that are now brittle, giving you rattles. When taking apart silicone spray is your friend, lots of it as you go for the clips, so they are at least able to slip off easier. Then replace all foam again, and add more dampening pads as well inside, as the originals are likely now well sad and crumbling.
The good thing is that by me I can get the entire lot as pattern parts, seeing as VW has been consistently the number 1 or 2 seller in the country, with Toyota contending for the other spot, and the VW Golf and variants are well represented in the spare parts market, with pretty much all the vehicle being available as pattern, or OEM from all the local suppliers, who made them for VW to assemble.
Standard joke you only cannot get the VIN plate as aftermarket.

Try SA ratpaks, a 7 day meal set in a box the size of your hand. At least it came with fuel tabs and matches, and I quite liked the one thong nobody would eat, the pilchards, so could always get a swap going. Coffee and tea together needed to heat up and soften the doggiebix that were included in there, and if it was moving extra protein. Never had one that was not either expired by a year or more, or close to expiry.
But found one of those fuel pellet packs this year, and, 30 years after I got it, and it already being 10 years old then, it still was able to light and burn with no smoke, exactly as designed.

No, that is a full wave 3 phase rectifier, as diodes are a lot cheaper than copper, so putting in 6 diodes, and only half the number of turns of thick copper (or for the cheap alternators the thicker CCA wire) to get the rated current output, is a lot cheaper than having to put in double the number of wire. Then make a larger case to fit them, and having to get much more expensive diodes, rated at 200V, as opposed to the regular diodes that are rated at 30V, and are designed to break over at around 40V, to handle the case of a load dump transient (which is part of the job of the alternator now, as electronics in a vehicle is so much more than when a generator was around to drive only a few lights and a coil with points), or a regulator failing and causing the alternator to go to full output. Ripple you see there 6 peaks per revolution of the alternator field past the pole pieces, because of the 2 phases, and at any time 2 diodes are conducting at the peak.
The larger lower ripple is because of the rotor turning once in the housing, and also the slower response of the voltage regulator modulating the average output voltage, as it is being aimed at a particular set voltage by the internal regulator module. Typically 14V4 when cold, and dropping to 13V8 as the regulator heats up, to closely track the actual battery temperature, but still provide a high initial current to charge the battery from cold, tapering off with time. With modern alternators getting controlled from the ECU the initial voltage set is zero for a few second,s to allow the ECU to gain control of idle RPM correctly, and start the cold start warm up and keep emissions down, then it is ramped up to get voltage to 14V4 for a few minutes, to provide a full charge to the battery. Maintained till the ECU sees the battery current start to taper off, as the battery approached full charge, sensed by the sensor on the ground lead. Then it will depending on the model, either switch to a 15V charge for a few minutes, to desuplhate the battery, set by a counter programmed per the OEM battery manufacturer as to best profile for this, or will drop the battery voltage to a set voltage as determined by ambient inlet air temperature, and engine compartment temperature (coolant return temperature) so as to not overcharge the battery, and all the time monitoring, so that the sensed ground current in the battery is close to zero, so the alternator provides all the engine and vehicle current draw.
this means that your alternator warning light comes on when the ECU detects the battery is being forced to provide current for more than 5 seconds, either due to the engine not running, or that the load exceeds the output 5 seconds after it has been commanded past 95% duty cycle on, and the alternator is not supplying this current.

@martymcfly1776 Yes by me, in the third world, even having that disclaimer does not actually mean they can sell as is, especially if it is sold as new. There is a warranty of fitness, and the first one that landed up before a court would have them told to remove that clause entirely, and rescind it on all the sales as well. Only way would be if it was sold as second hand, with no warranty, on public auction, in which case the sales agreement would have to clearly say the goods are used, and have no warranty, sold voetstoets. No auctioneer would risk their registration selling stuff they knew was defective, just sell untested, and at a low cost.

Plus the material used for the walls got thinner and thinner, till they had to stop, because the craft was almost at the point it could not support itself under earth gravity. So thin that the crews who were building it had to take care not to step on, or touch the hull, as they could destroy it merely by putting a foot on the surface, and tear the skin. This would mean scrapping the entire craft, and building another, as the skin was too thin, and the joins so small, that they could not remove a panel and rivet in another, as the material would likely tear. The end material was barely thicker than the aluminium used to make cans, and just as easy to dent when not pressurised.

My father crashed 2 aircraft. One a Gypsey Moth during training, and the other was a Lancaster, that sort of fell apart around him over the Bodensee. All he remembered, before the 6 weeks of black, was the plane, and his parachute, being on fire, and him telling his crew to bail out. Austrian nurses told him they picked up his body in a snow bank under a pine tree, and thought he was dead till the coroner found a heartbeat. Then patched him up, removed most of the broken pine tree, broken glass and shrapnel from him, and did a massive skin graft to fix the burn that covered his entire back. Basically broke almost every bone in his body, but the Austrian doctors and nurses put him back together.

@hawk_7000 More likely they were in a hanger far away, and habit of "we never use them, it will only be here an hour at most" meant they were in the hanger still. I remember my erstwhile trainer coming in white as a sheet, because he was out flying, and they had a fire warning, so put down on the nearest thing to level, then the pilot kept the helicopter planted down hard, while all were out looking for suitable boulders to chock the wheels. Only when the wheels were suitably boulder impeded did he finally power down the engines, and pull the fire extinguisher handles to put out the fire burning up on the top, then they went up after rotor stop and put the remainder out.
Radio call came in for somebody to bring out the required hydraulic hoses, the tools to change them, torches, a lot of hydraulic fluid to fill the reservoir again, some cleaning material and something to drink. He left 07H30, and came in white as a sheet at 15H20, from what was to have been a 2 hour training flight. Next day fire bottles replaced, and the extinguisher sent in for service, and all the rest of the fleet had those same hoses checked, and a month later all new PTFE stainless steel braid reinforced hoses installed in place of the original rubber. Took a day to wash that oil off the chopper, it was literally in every panel and compartment, along with the soot.

@patrickday4206 They probably did keep the car in a straight line, as likely without it the one wheel would have locked up, and then it would have drifted off to that side, and then gone off the road. Biker would have survived, but the car driver would have a closed casket ceremony, with very little in there either, if at all, unless they buried her with large pieces of car as well.
Safety restraint systems, like airbags, crumple zones, seat belts and such, do not work very well above 50MPH, and the car basically at 87MPH will shred itself apart in the ensuing rollover and cartwheeling. F1 vehicles survive because they put insane amounts of care into making a cabin cage that will survive 200MPH collisions with the wall, but you cannot fit that into a regular car, with standard non custom made seats, and custom made multipoint harness and helmet, that is also attached to the seat frame.

Only thing that would make this worse if the cleaners were not sent by their landlord, but by another, and they got the wrong unit number. But with the cleaning crews, they should by now realise that, when cleaning out a property, they really need to remove all stuff, and place in a storage location for 2 months, and keep it there secure, just for these cases where they go to a place and it is full.
Going to guess that whoever is responsible is going to pay up a very large settlement, or they are going to own that unit , or both. and yes cleaning company should have realised that what they have is not just a few boxes left, but an entire household of stuff, and asked why, and made absolutely sure they have right unit, and that this probably will end up in a court case. Any "reasonable person", going into a unit, where it is full, to clean, and seeing this contains a full household, should have realised there could be issues, and just putting the stuff outside, unless they had a court order directing them to do this, was going to come down badly on them. If there was a court order, then they should have verified they were at the correct unit at least 3 times, and confirmed that they had to move all out to the kerb.

@thelasthourgetready They actually work better under water, as the shock wave will be better coupled to the blast. This one would have, if it was in it's as manufactured blast ability, have collapsed the concrete wall and lighthouse there near it, and also likely have severely damaged the other side wall as well. Original design has a delayed detonation after impact, so that it is well underground.
This one hitting water probably was not enough shock to allow the timer to start, or it and the backup one were defective or damaged on impact, common enough with these as the fuses are not amenable to testing on the production line.
Designed to be a good depth underground, and for the blast to generate a massive underground cavity into which nearby structures would slump, and the blast wave coupled to the ground would shake buildings nearby off their foundations. Also used against reinforced concrete bunkers, detonating part of the way through the concrete top, spalling off the interior roofing in a blast of fragments that destroyed all in the interior.

Yes average speed fines are becoming common, so much so that the one highway has them, because people speed down the hill, and there have been a good number of fatal accidents. They recently upgraded, installing a third camera half way, because the number of turn offs mean that some speeders will do 200kph plus on the uphill and downhill, because they turn off before the second camera. Now the common exits and entry points for speeders are covered, and the others are such (old road, 300 years old, and only upgraded for higher vehicle flow rates, with turn offs all along it) that speeding into and out of them will result in your vehicle meeting steel barrier rails.
Average speed means I never get a ticket from there, and i can chuckle at those braking for the cameras, thinking they are point speed cameras, while they flew down, so get the love note via SMS a day or three later on (not posted, that takes up to 3 months....) or get a list of tickets when they go to renew the vehicle registration, instead of the tag.

South African POW's, mostly stayed, I had 3 Italian POW's who stayed, and brought out their wives/girlfriends as well. Last survivor is the wife of one I know, now 92, and still sprightly enough. Comes from a half glass of watered down wine with lunch every day according to her.
The husbands had built bridges, built buildings and made roads, and after the war they became engineers, machinists and such, and did well in it. Still an Italian club around, though mostly composed of the children, not many of the original members left.

Yes the steel did have quality poorer than modern steel, but it all did pass the shipyard testing for tensile strength, as they did test all batches that way for all materials. That only came in in WW1 and WWII, when they used sub par steel that had high sulphur content, which made it become brittle in the cold weather of the Atlantic. However the steel did still work to absorb the energy and deform, and the rivets that failed were operated well past design spec. Yes the modern testing did show they were not as capable as the best of the day, but none of them actually were defective by the standard testing of the day, even if they would have failed when cold. But test at room temperature, around 15 to 20C ,and they passed, even if they would fail at -15C.

BMW offers it on new vehicles, where for the first 3 years you only pay for fuel, top up oil and tyres, the rest, aside from accident damage, is covered. Of course you are paying this in the price, and they are amortising it over a 5 year period, so after year three, when you get out of the warranty and motorplan, you either pay at BMW dealer price for service, or will buy the 2 year top up plan, which is only a little cheaper. They know they have you for those 3 years, paying interst on the services before you need them, and they also know the vehicle will not fail before then from history, and any accident damage they will bill you for. Scrape the belly pan, new one, at your cost, dent from a trolley noted and then your excess for insurance will have this charged under "betterment" if you claim.

The modern way to get accurate time is a set of GPS locked hydrogen maser clocks at each location, so that the GPS signal, knowing your accurate location, and a long enough time, allows both atomic clocks to keep near perfect time with each other, and then you record the data with a time stamp and use a compute cluster to correlate the data to match each waveform to the corresponding one from the other. From that determine the delay due to distance, and solve the trigonometry. You have to sample at the carrier itself, which generates truly huge data sets, but you can use local computation to reduce the data volume, without sacrificing the time information, and once you have the data you can also average over a few minutes, to both get a motion vector compensation for the earth rotating, and also then the vector for the spacecraft moving.
Before you would record both outputs using magnetic tape with an accurate clock, a Cesium atomic clock that was in a suitcase, that got flown there powered up, keeping the time from the master clock, and used to time stamp the data on the magnetic tapes. Then the tapes were flown back, and a room full of mathematicians solved the problem. Current methods rely on a high bandwidth link via the public Internet to do the backhaul in near real time, and NASA has the computer clusters to do the data handling as well in near real time as well, thanks to improving technology.

Brake seals are all made from a synthetic rubber that is perfectly compatible with brake fluid. Other fluids though will make them start to swell, as they are absorbed into the seal, and this means the seals grow, and no longer can slide, and the hoses grow soft, and are no longer capable of holding pressure.
The swollen seals in the master cylinder, the calipers and the back wheel cylinders now no longer can be moved back to the resting position by the release of the pedal pressure, so the calipers stay in contact with the disks causing a lot of extra friction, the drums will not be able to relax to the off position, and the master cylinder can no longer return, trapping fluid in the system under pressure, as as the brakes heat up the pressure increases, making them grip more, till the disks and drums are red hot and the linings are totally degraded and worn.
You also no longer have working brakes, and as well if you have ABS you now also need to replace every rubber seal in the ABS control unit, which means a new ABS block, and for older transmissions where the trans gets brake pressure to disengage it, you now also have to replace the actuator in the trans as well.
In a pinch, if you are totally out of brake fluid, you can add in pure alcohol to the system, as that is compatible with the seals, though it will need to be over 150 proof, to not cause damage, and will need to be flushed fully with new fluid as soon as possible. In ultra cold climates the brake fluid is mostly alcohol, either methanol or ethanol, as it will not freeze easily, though synthetic esters and glycols are more common there, but they are miscible with alcohol.
With modern cars fluids are now critical, if it says use x fluid, use it, do not just chuck generic ATF into the power steering, as you will run into issues, and the same for trans fluids, where there are now dozens of different fluids, and the wrong one can be a very expensive fix. Even manual trans the fluid is critical, many vehicles need a SAE75 oil, and will balk with SAE80 oil, or grind with SAE70 oil in them, and some are even more critical with what they need, you put OEM in only. Even engine oil the same, SAE30 is not going to work on many, especially newer vehicles where the oil viscosity is critical in engine operation.

Going to say the stuff started with a weak battery, that then dropped voltage as the vehicle sat, meaning different ECU units stopped working at different points, leading to the BCM and ECU loosing comms with the TCM, so the one set error codes, and then the error was left, and with the new battery the modules came back up, and communicated all the errors, refusing to allow start via the ECU because it was unsure of the status of the transmission, thus disabling starting till it could get a valid status. After all safety circuits only allow starting in neutral or park, and with an unknown status of the trans starting could be in gear, so default to no start till scanned and cleared.
Other shop should have, as a first ting, looked at stored codes, noted them down, then cleared them all, as there are plenty of errors that will result in a no start, due to the modules inhibiting it. Either no scanners, or they are only able to be a box and panel changer. till, good money for you to fix their mistakes, just that it costs the customer in the end a lot more throwing the parts cannon at it, and not actually sitting and looking at it first. But we all often will do that, hopefully leaning along the way.

Yes, just means they do not deal with that manufacturer more than once a year, so do not want to have the software cost, because that $50 per make adds up if you are dealing with multiple scan tools, and multiple makes of vehicle. Also some will charge you per use, unless you pay a stupid annual fee, or are a registered dealer for them, in which case they stop charging per time. Some just flat out refuse to deal with shops outside the dealer network they have, you have to go to them for coding of parts, or have a cracked version of that code around. Then you get the green tractor company, who will invalidate the warranty if you do not use the dealership to do everything, even change the oil on the more expensive things, and you have a very expensive field ornament till they decide to come fix your broken one.

Here the bolt cutters that are waist high are called "The Free State Lockpick", from their use by farmers on the farm, where the farmers will, every year, go out and buy 200 plus locks, all keyed alike in sets of 10, for use on the farm to lock stock gates. Every farmer also has in the rear of the farm truck at least one of these bolt cutters, used, along with the now depleted box of locks, to open gates that either he cannot find the key for on his farm, or where the key does not work. So 5 seconds later there is now no lock, and the pick up goes through, and 10 seconds later a new lock is on.
They also are useful for fencing, seeing as you can use them to handle barbed wire at arm's length, and not get hung up, and you can also cut the wire no problem as well, or lightly nip it to tension the wire on a post, or wind the wire around itself to set the fence. Those, along with a set of fencing pliers, are what I use for barbed wire and other fence work, as it is a lot less painful than gloves. The bolt cutters also work on the harder bushes when you need to trim them, but do not want to go fetch the chainsaw.

Biggest problem, aside from running out of ammunition, is that they would soon run out of medical support, so any injuries that, in the modern war, are not even considered dangerous, would be deadly. A scratch and tetanus, and any infection without antibiotics another slow dying. After power and ammunition run out, they are back down to being as effective as the locals, and worse off, in that the locals know the terrain.

Going to guess the reason for poor video on the converter at 5V is interference from the boost converter, as those do need a little bit of extra filter capacitor on the input and output to get lower noise.The converter also likely runs internally with a few small switching supplies to get the voltages it needs, probably a rail of 3V3 for HDMI, audio and video input IO drive, a 1V8 for the chip itself, and likely a 0V8 supply for the converter core of the chip.
A better boost converter is to dump the XLsemi 6009 based one, and instead use the MT3608 based ones, as they have a much lower noise floor, running at 1.2MHz, instead of 400kHz, and thus the filtering capacitors are much more efficient. The boards themselves are pretty much the same price, and nearly the same output capacity, which is amazing in the single tiny SOT23 package, and the power loss in the converter is minimal, 97% efficiency and it really is tiny. Just no display on the board, so you will need to set it with a DVM before connecting, and make sure, before applying power to turn the little multiturn Bonrs copy pot to minimum output voltage, as otherwise it will do it's level best to boost to 100VDC.

Oil yes regular changes is important. For a cheap and safe engine clean simply add in a half quart of SAE30 HD3 diesel tractor oil in a few days before doing the next oil change. High detergent oil for farm tractors, it will clean a lot of the gunk off the engine, as it is meant to keep soot in suspension for farm tractors, that spend a lot of time idling.
Yes filters almost always have a bypass valve ( though some of the no name brands do not actually put it in, adds 10 cents to the cost) that will typically open at around 20PSI pressure differential across the filter media, on the theory that having oil flow, even if dirty, is a lot better than no oil flow. But having this valve operate does mean all the junk and tramp metal the filter is supposed to remove, and a lot of the stuff it has removed, and which is inside the can, now can travel past the filters. Not great for bearings and the rotating surfaces, and definitely not great for small clearance holes, like lifters and variable valve timing actuators.
Great on the oil, I got some filters for my car cheap, old stock ones that were sitting at a store on a shelf, at the price they were selling them in 2008. So next service filter is there already. Will differ with you on the dry filter, if the surface is just wiped clean, yes you can put it on dry, as the oil film on the housing will lubricate it, but if it has been washed clean with brake cleaner, oil the filter seal. I just grab a bit of the old oil and wipe it, then pull that seal out, flip it over and oil the underside as well, and make sure it fits back in the groove properly. Recently had a no name filter which, brand new, was leaking, I assume from the metal face not being true, and thus the seal not holding. I only buy 2 brands, GUD or FRAM, as they are locally made by me (20km away), and are the OEM brand for most vehicles in the country. 1 million Toyota filters made by them, they pretty much have it right.
As to tyre pressure, the top end of the vehicle manufacturer spec is the one to go for, as yes that is the one for either heavy load, or for economy. You want comfort make sure you have a high profile wheel and tyre. Painted on rubber and all alloy is always going to be harsh ride, and noisy.
Drivetrain yes likely dry universals, or they lost a needle when putting them in, grease will tell you quick if the UJ was dry, or if you are spending a hour changing both sides. Gearbox simplest first test is change the fluid, fill back to level, and run it, as otherwise the issue is a sticking ball inside, or a seal that is leaking when cold internally.

Bearing races are in general fine to intermingle, if they are from the same manufacturer and the same batch, as they will tend to be all ground to the exact same dimensions. You can even use different batches, but for close tolerance they might be slightly different due to the settings being slightly different between runs, but changing manufacturer is iffy, but still you will get good life out of them. Only with precision bearings will you have to use matched pairs, but if you are using them in a vehicle almost no bearing is in any way going to fall in this category till you are into parts like the AC compressor, and the crank and main bearings.
Fun thing is that VW rear bearing is very commonly used on trailers, so to repack the light duty trailers it is a lot cheaper to go buy the aftermarket VW rear bearing kit instead of the trailer manufacturer kit, and use it instead. Normally the caps will not fit off the bat, so you need to either reuse the old one, or spend a bit of quality time with a hammer to make the new cap shrink to fit the diameter.

I would say the 5Mp cameras are likely cheaper than the old ones, as they are current products made in large volume as security cameras. So the cost to use them is more the updated firmware in the car to handle the higher data rate, and the different front end possibly to interface with the camera, though likely it is all still a standard security camera rate, and can be done with simply flipping bits in the front end interfaces. Thus actually no cost to improve the cameras, though probably most of the time the higher resolution will simply be downsampled to lower resolution, as after all lane departure and such really only works with edges, so more data is bad. Higher resolution possibly to improve sign recognition, and of course better in car video recording, though likely with a higher data rate a larger SD card for storage now needed.
Cutting the sensors likely just relying on the computer and stored data, plus knowing accurately vehicle position, to provide the same level of detection, though it will not help against things moving after the image goes out of frame.

Here by me there was a fire in the deeds office in the 1970's, destroying a lot of the original plans, so there are massive lots of properties with no actual plans and boundary locations, just the physical, and whatever has been surveyed in the interim for either the next house or further from the datum point that incidentally marked the boundary out. Some the only plans are quick sketches, from somebody applying for an extension or alteration, where the plans they submitted were considered to be accurate and correct, as there was little way to prove otherwise. Sales often were the only time these were done, grandfathering all the stuff into the city GIS, though they could look on the aerial photos over time, and see massive differences, if they looked carefully, but those were considered as not being good enough to draw from other than to confirm construction.

@wombatperson Soviets used that narrow width flat screw for decades, as they had standardised on it, and it is a lot narrower than the Western version. Same for the connectors, old patterns with the focus on interchange between wildly different age equipment, as they tended to keep equipment in operation for many decades, and not upgrade at all, so long as it still could be serviced and worked.
After all this was a central economy, where even getting a light bulb involved a lot of paperwork, leading to the black market being big in selling blown light bulbs, especially those with visible blackening on the glass, as selling the faulty ones was not frowned on, but they were difficult to get as a consumer new. So buy blown ones on the black market, and simply swap them at the factory, wait a day, then report them as blown, and the factory would change them, of course the electrician or store keeper keeping the blown ones, to sell as used.

Well, likely the new part will come, and as the machine is busy, and the repair holds up, they will not bother to put it in, till around 5 years later on when they need one for another identical machine, and take the one in storage out. Bronze on cast iron works well, and yes the bronze is stronger than the parent metal, and at least is a lot more ductile, as I have seen a few cases of the bronze repairs being a row of repairs all next to each other, with just a tiny cast iron seam between them, as the overloads exceeded the cast material capability, but the bronze was fine.

Would also suggest getting a trailer relay unit, so that you have the trailer load not on the existing vehicle wiring. Very important on modern vehicles, as the BCM is very often likely to fail with a short in the trailer wiring, though some do come with the trailer module already there, and often enough also will show faulty trailer lights and connections up on the cluster as well.
Made my own, ran a fused wire direct from battery to the rear, and put 4 relays to drive trailer wiring, with the 4 relays driven from stop, left and right indicators, and the side lights, as all vehicles by me are regulation bound to have separate turn signals different from brake lights, EU spec. Thus any failed trailer wiring will just blow a 10A fuse in the front, and not blow an expensive ECU, disabling the vehicle till it is repaired or replaced. Also added in a simple current monitor, which will light up a small green LED on the console, to show that you have at least one functioning indicator or brake light.

They simply take that contaminated fuel and put it into a bulk tank, diluting it with a lot of petrol. The tank at the garage they simply pump dry, and then fill again, as a small amount of contaminant is not going to matter. After all you get fuel stations with a single nozzle that dispenses either petrol, diesel, E90, E85, and the small amount in the hose is going to be going into the tank of the next customer irrespective of the fuel selected.
Most common thing is that the tanks will get filled with illuminating kerosene instead of diesel, as the IP is cheaper, so diluting the diesel is making more profit. The leaking tanks the water is normally pulled out daily, though there have been a few dishonest pump and attendant cases where the pump fills up the tank with a few thousand litres of water, and then the fuel, and then the "excess" fuel is put in another tank elsewhere and sold cheaply. Attendant then dumps the water out the tank to waste, and fudges the dip readings for a few days till the error is gone.
Of course by me the refinery was phasing out the TEL, and when they finally emptied out the TEL tank they found a nice crack in the bottom, that had been leaking TEL into the ground for decades. Then the guy with a house near the pipeline who dug a hole in the ground, and it filled with fuel. Refinery spent a good bit of money first fixing the leaking pipelines, then also digging up all the properties along the route, and replacing the first 3m of topsoil, plus the garden and fences, all for free.

As the ads are only up for 24 hours or so, simplest is to filter the ads that last under 2 days for scrutiny, and also for insta to keep the images for longer internally, with those short period images being moderated more, and the accounts linked to them. Also easy to search messages for the words of other methods, including variants of the name, and anything that matches more than 30% of the name within 30 characters, plus at least 5 numbers within 30, should be assumed to be illicit and sent for moderation as high priority. But that of course means that they need need to hire cheap mechanical turk labour in third world countries, and train them, and pay them the $2 per 14 hour day that they do.

@bogglesbiggins1101 Because cops will not bother, and the bike generally is a lot faster than a police car, plus can go through gaps as well that the car cannot easily follow. however the rider probably uses that route often, and it is easy to run a DMV check on all bikes that model and colour in the area, and then see which owners fit the age range of the rider, and then simply go to the registered address, and view the bike. No plate, tow it away, and illegal size the same. But not going to be done, because that takes 3 things the police do not have, ground work, thinking ability (police do not hire intelligent people as basic officers deliberately) and also wanting to be proactive about crime.

Seen a similar thing on a Ford 1.6 CVH engine, would start, but only run with throttle held near full, and not idle. was looking and wanted to check if there was actually oil in it, so pulled dipstick with engine running. Idle dropped to near normal, with still full throttle, and on removing oil filler, it dropped stone dead. We could have rebuilt it, but instead it was quicker to instead send it to Ford themselves, and get a complete new engine from them in return. Not cheaper, but the engine was needed urgently as otherwise there would be massive delays and lack of critical equipment.
This engine was used to drive a hydraulic pump, and this in turn was a specialised vehicle that there were only a very few of, so a missing one was somewhat of a crisis. Not over revved, as they all had limiters on them ( though often bypassed, so we locked out the throttle plate range instead with a welder, to hold that limiting bolt firmly in place), best we could guess is somebody ran it without oil, or with low oil level, and cooked the bearings and rings, or had not checked coolant, and the engine had overheated. Same end result. Otherwise those engines were pretty robust and gave little issues.
Those VW 2.0 TDI/TSI engines also are the power plant on a lot of fork lift trucks, where they live a very hard life, long idle times, frequent stop starts, hard running when cold, and generally just abused. Amazingly they do survive that quite well. Saw them often at plants, pop that cover and the VW logo is there, while the outside is quite a different logo.

Yes, will likely scrap routes that are not profitable, and also cut costs down by selling off aircraft, selling off maintenance facilities, and getting rid of headcount all over. That will make for a good 4 or 5 quarters as those do not show up yet in reduced passenger numbers, and till the aircraft need expensive outside contractor maintenance, that comes in to hit hard as the airframe hours mount up. But they will have sold off the shares at a massive profit, leaving behind, after another year or so,an airline in serious trouble, with plummeting revenue, and mounting costs, because the core attributes have been gutted out, the assets sold off at pennies on the dollar in future revenue, and only short term profit that got taken out almost immediately in dividends. SW going to join the other airlines like TWA, that get taken over by another at a massive loss, and be carved up for scrap metal.

Especially the top management, as in regional and national level. Branch managers that are tied because they literally have no working computers, or even paper to print receipts on, is something from the top. For a long time the post office receipt came printed on National Lottery paper, because that was the only paper the whole city post offices actually had. I would take copy paper there for them to use when getting a parcel, because they could not print the documentation they need to have. Even staples and pens for the same reason. Then eventually the branch was closed, but luckily the staff were absorbed into other branches, as I had known them for 20 years at that time.
This year I stopped paying for a PO Box, because it got 15 letters other than junk in the year, so went electronic for most and changed to physical address for the rest, and the 6 weeks it takes to send a letter, literally in the same post office building, is beyond a joke. not the staff, who are for the front mostly overwhelmed but still give good service, but the back end and poor top management who are totally out of touch with reality, like most SOE top management are. more concerned with hitting a metric that they made up than actual service.

Bought some the other day, just because i needed some 5mm drill bits for rivets, and am tired of the bits wandering as well. Plus you get 2 chances to break the drill bit. Will also say that if you have the misfortune to do work on 316L stainless steel that has been work hardened by being spin moulded, and not annealed, you will not go wrong budgeting one drill bit per hole. You might be lucky and get three holes before the bit turns into a friction stir rod, but generally just a shade over 2 holes per bit. Last few I had run out, so yes that 600W AEG drill was quite happy to cook the holes through it. The 800W Bosch could not turn fast enough, though it does have enough torque on it to drill 25mm holes through reinforced concrete, never mind if there is actual reinforcing rod in the way, plus the plain bits are cheaper than SDS. The 5mm SDS bit lost the tip, though it made no difference to it drilling, still went in fine, just a second more per hole. 6km of conduit with one drill bit is good, till I borrowed it from the electrician and found a bit of loose granite. Still in use as a centre punch. Building sites are brutal on power tools.

Realtime is very common in streaming, as you definitely need to have the packet stream going out in order with low latency in say broadcast, where you need to be sure that all incoming data is processed ( transcode, just a scaling to peak limit) with as little delay as possible, so that the presenters can get a near real time feedback audio, as anything past 50ms will result in uncanny valley audio to them, and make them stumble, especially if this delay varies with time. So small buffers, really tight timings, so there is minimal delay on things like audio, and same with video so that you do not lose sync between video and sound. Common in big broadcast media, and in things like broadcasts of live events visible in the stadium, where you need to have the big display no more than 5 frames or so behind the image being captured by the cameras, and the same for the audio support of say a concert, it has to be almost no delay, or it starts to sound weird.

Standard joke about flying on them was, if it does not drip oil on the ground, do not get in it, because that means there is no oil in the engine. That oil cooler was always going to leak, to the point the operators always had a ready supply of wooden dowels with the right taper, to tap into the leaking passages to block them, and a hammer, in the cockpit. Only time that did not apply was the turbine conversions, there that oil cooler was gone, replaced with a much more reliable modern one, and if that leaked you were not going to make it. I saw plenty of oil coolers with up to a third of the passages blocked off, but the aircraft would still fly, just use a little more of that thick goopy oil. Like molasses when cold, but hot was like water.

Had that with an AMT box, after changing the clutch. As no dealer support, they went bankrupt and closed, and left the country for a few years, and the new models and dealers do not support older models. Plus spares come from Malaysia via the UK, as they do not deal direct with my country for political reasons. So to teach the TCM about the new clutch, a bit of driving, using a few hills, so as to have lots of start stop cycles, and then drive it so it would hunt up and down the gear ranges a lot, and after around an hour the TCM had learned the new timings. Had to rebuild the AMT hydraulic pump, as the brushes wore out, and the cost of a new one, from Renault, was almost the value of the vehicle, so a new set of $5 brushes, salvaged from a Bosch alternator regulator, was a good fix.

I bought a can once, on special, and actually used it on my sister's car, as it did not come from factory with a spare. Now she has a working spare, and the can got her through a month of not being able to get to fix the flat. Did check my spare tyre, and yes it was flat, but you have to remove it from the boot to check it. Also with that spare under the car, please take a can of dry chain lube, and spray on the threads of that stud, so it can actually come loose off there when needed. Dry lube, so it does not attract dust and become a dust block. Same for the jack, as they do not come with much lube from the factory, so spray with brake clean, and get the grease off, and spray with chain lube, and run end to end, plus on the bearings and pivots, and then wrap in a cloth, sprayed with a thin coat on the inside, to both protect from rattles, and to provide you with a cloth to clean your hands when changing.
Yes have had the pleasure of getting the spare off, using a hacksaw blade, on the side of a highway, because the steel bolt rusted fast to the nut. Fixed that the next day, stainless steel bolt, and a loose fitting nut, with a nice coat of molyslip between then in the threads, and a split pin to prevent the nut coming off. Was a tank hold down bolt, but 10 minutes with a grinder and a welder, to make a plate that was used to fix to the trailer chassis, and it never gave any issues ever again. Worst came to the worst use a shifter and pliers to undo the 2 M8 bolts that held it down, and slip through the centre hole. Next time I had to change it, again on side of freeway, after finding a nail I assume (only had the sidewalls left, after the middle shredded itself off, actually same spot I twice had to dodge a Hiace half shaft and wheel assembly complete, as it came past me) it was so easy to undo, jack up with the jack, and get the bolts off the trailer wheel.
Tip as well, lube the threads on the wheel fasteners, light coat works, and use a torque wrench to put them on, not Cletus and turn till it half way snaps. Impact driver to put them on means you never get them off with the socket in the car kit.

My father crashed one, after leaving the one wheel in the middle of a pothole on the runway, hidden by the part time airport having had heavy rain in the morning, and on approach in the late afternoon my father had seen the shiny water, and thought that the airport had finally tarred the runway instead of being grass, and was just late in updating the charts they had with outside countries. Nope, was water, and on landing he was getting spray, and then the one landing gear left. So he decided to cut power, using those magneto switches, up there for making turning off the engines a deliberate action you could not do by accident, and went gear up.
So skidded to a halt outside the terminal/bar, where the part time ATC was belatedly firing a flare into the air to denote to go around. Passengers did not notice the accident, aside from them not needing a ladder to disembark, and them noticing the 2 bent propellors. Long distance phone call was made, via a good number of operators, to the destination airport, and the actual owner of the aircraft that he was doing a ferry flight on. Next morning the new plane was there, dropping off a crew of mechanics, 6 blades for the propellors, and the left undercarriage complete, and the tools and jacks.
This then left with the paying passengers, down south to Johannesburg. A week later the aircraft, now repaired, flew back down with the mechanics and the damaged parts. Very likely I did fly on that exact aircraft, years later, in the military, as they got the entire fleet as the airline upgraded.
My last flight in the military was on one, and of course it had issues, with me and the FE leaning out to look at the gear, as the right side was very unhappy to show green. I was the human chain, holding his belt, and acting as audio relay, while we both agreed it looked like it was over centre, and thus locked. Best landing ever on a C47, smooth, almost no bump, though slightly marred by having a fire engine keeping pace with us, with foam cannon ready to use. Got in to destination 6 hours late, and when asked, I replied the C47 broke down over the last stop, and we all had to get out and push it the rest of the way.

I guess his parts store is local to him, and has deliveries out 3 times a day, so as to allow this. By me that would be a guy on a bike, something small, around 80cc, and with a driver who occasionally uses the road to drive on. As we joke, the biggest biker gang in the country is the 60-60 gang, which delivers for the one nationwide chain. My friend knows all the drivers in her area by name, and they greet her all over as well. They get around $1 per delivery, so do around 60 deliveries a day, but do not own the bikes, so maintenance is not their problem, though fuel is.

When you left school with being a sub functional literate person, and with no job prospects, and criminals are seen as being free with cash, this is appealing. Education wise the spend per pupil is the highest in the world, yet the only way to get the desired pass marks are to drop standards, then drop the pass mark to anything over 39%, and those under that get a conditional pass. For every teacher in a class there are at least 10 administrators, all of them earning much more than a teacher pay, and all of them having school holidays off. Telling thing is the number who drop out from grade 1 to grade 9, officially mandatory, and then a massive amount at grade 10. Universities have all had to add on an extra year to the degree paths, simply to teach what the schools should have taught, if they wanted to keep international accreditation.

@poppedweasel The British created the word Concentration Camp, Scorched Earth and considered every person to be a military member, and shot first. They were after the gold and the diamonds, nothing else.
They also had incredibly stupid leadership, who would only use the manuals that they had been taught for generations worked, from a century or more before, and were absolutely unable to consider any change in tactics as an option.
Nothing much changed between the Great War and the 2 World Wars until the leadership was totally replaced by new thinkers who, like the Canadians, had the luxury of difference, and the ability of the leadership at the Regiment not being as inflexible due to them having had to develop so far from the hidebound British structure.
As well, the pronunciation of the names and places hurts, especially as there are enough sources available to get the pronunciation of every name and place correct.

Toyota can accept a lot of error in alignment and still drive fine. Likely they, from the damage, sideswiped a Jersey barrier, damage is consistent with clubbing the base of one, pushing front suspension back, and the rest is from the side of the concrete. Yes a thing that should have been disclosed, though the painter who worked it did a poor job, orange peel all over, fisheyes and clearcoated the dust, plus failing to fix the edge damage on A pillar. But matched the colour well, that charcoal colour is actually a really hard paint to match properly, too bad it was applied poorly. Rushed, poor prep of surfaces, and dust in the area.
Yes if the price reflects the fact it was damaged, you take it to an actual alignment place (definitely not toe and go) and get that subframe correct, it should give no issues at all, though your range control will absolutely need recaibration, as the aftermarket bumper covers are different to OEM, which get matched at the factory before they get on the line, and this is then programmed into the ECU as it finishes the line.

You can easily buckle the rear of the frame with that kind of impact, as it will crumple as protection. That the manufacturers do not make that section as a separate piece, that you can simply bolt in as repair, is because those extra 4 inches of steel, and 8 bolts, was costed out as too expensive. Just like Ford and the Pinto, using a plastic shroud was an extra 60c on the price, despite it being required in the other major market. That they tested one "off the assembly line" to prove it was also faked, they deliberately brought one from the Canadian plant, that had the shroud installed for this market, and of course it did not catch fire, by design, while the US ones continued to burn, because they figured the cost of the lawsuits was cheaper.

@YouCensored Seen plenty of PTFE wire with a pink tinge or a pink stripe in the insulation, there generally on sealed assemblies like motors, to allow you to indicate polarity on the motor during further assembly. Though yes the tiny amount of dye will be totally insignificant here to overall burning of the wire in the pure oxygen atmosphere when it got an ignition source.
With pure oxygen at atmospheric pressure and above, many things that are normally considered fine, like lubricant oils and greases, are forbidden, you have to use rather esoteric lubricants, like molybdenun sulphide, and powdered graphite, as lubricant, and even skin oil from handling is considered to be a contaminant.
Even such things like crush washers are a problem, they have to be copper, or ultra pure aluminium, or nickel, as the first application of oxygen to the newly crushed surface exposed to it will nearly instantly form an oxide layer, so the pressure has to rise slowly, so the reaction is not too violent during this time, and the heat can be dissipated. Not so bad as handling fluorine gas, where you have to do this even more carefully, as literally the only thing that is keeping your entire apparatus from dissolving, is the thin film of metal fluoride that is coating all surfaces, from the initial introduction of gas. Oxygen is only slightly less reactive.

Yes still remember using those kits, and even rebuilding master cylinders, as those also had kits. There were a few engineering companies that also did sleeves, making the bore standard size again, and stainless steel, so it would not need oversize kits. They are common in vingage and veteran vehicle repair, as often you cannot get the original part any more, so either resleeve the cylinders and get seals, or you have to modify (a sin in the classic car show market) to use a compatible modern unit. Even did rebuild a few Morris Minor indicator stalks, rewinding the coils that had burnt out, using modern enamelled wire which had a much higher temperature rating over the old varnished wire, so the new winding would not fail again. Getting those old rivets out was a pain, especially if you needed to get the rusted ones out intact.

Input yes you can use a simple voltage divider, but the optocoupler works well to get some isolation, especially if you use a 4V7 zener diode in series with the LED to get voltage immunity to the signal, so a blown bulb does not leave the brakes on all the time from stray voltage.
Resistor divider you also need a set of diodes to keep the voltage from exceeding supply rails, along with a small capacitor (roughly 100n) to provide noise immunity on the input.
Incidentally reed relays work well, small, easy to drive, and the contacts interface well with MCU inputs as well, as they have very little bounce. Just have a pull up resistor to provide 2mA of contact current to keep them in good condition, and it works. I have added trailer relays to my car, as I do not want a faulty trailer wiring set to blow the BCM up, and used 4 relays to do this, using the existing lamp wiring as source, and an extra fused power lead from the battery. In the power line is a reed relay, with the coil replaced with 12 turns of enamelled copper, there to close the contact when current is over the draw of a 21W trailer lamp, and then the reed is powered from the 12V supply, and a lead runs off to a LED near the dash, that lights up whenever I press brakes, or turn, with trailer attached, as a confirmation that trailer indicators are working, and at least one brake light still works, and the plug is connected.
Will guess your TRS80 issue was simply because the original designers ran out of space in the very limited ROM, and thus to get space to fit all the headline specs they had to sacrifice some things, and the full keyboard debounce was chosen, simply because it was not an issue with a brand new keyboard, or only minimally so, only getting worse as the keyboards aged and were made cheaper. New switches with clean contacts minimal bounce, but as they age, and the contact surfaces, with only a very small current, get dirty, there is a build up of resistance till the force is enough to break through the film.
That is why industrial logic almost always has a 24VDC rail, and 10mA of current flow through a switch input, even if it is going to a MCU input only. The voltage is high, and also the 10mA of current, along with the 22n to 100n input filtering capacitor, provides enough energy to always clean the contact surfaces, so allowing them to be reliable. 5V logic needs that 10mA of current flow, and gold plated contacts, to be almost as reliable, but most keyboard designs, due to the demands for low power, and also limitations of the CMOS and older NMOS designs in ability to source current, only use much lower current instead, and thus the need for software debounce increases as the key switches age.

Easy for apart to have faulty heat treatment in a batch, and not have any idea this happens, if for example your treatment profile changed due to a failed sensor ( common enough in these ovens in industry, and they can degrade slowly before failing totally) and you only found out because somebody studies the logs in detail, and noted they took too short a time to cool down. Also could have been a batch of the steel was contaminated with impurities, or was the wrong mix in the furnace, or picked up the previous batch alloying metals from the lining and slag.
That they identified was good, shows QC was doing the job properly, followed up with the suppliers to review them, and that the test samples, either customer aircraft that are serviced, and have all wear items inspected correctly to pick up abnormal wear, or laboratory accelerated lifetime units, are being properly reviewed.
Rather that, than they just put in an upgraded part for spares purchase, and do not confirm that this part is going to need replacing due to it being faulty and having the recall. GM ignition switches anybody?

Still is the ancestor of them, though the Saturn guidance system was developed in parallel with the missile guidance systems, as both were under development by the same companies, at the same time. Thus a lot of the problems share common solutions, though the modern ones have moved mostly away from mechanical gyro platforms, and instead use solid state gyro units, and rely on computers to correct them for drift, as that can easily be characterised during assembly and test, as you can use a reference platform to allow one axis at a time to be decoupled from rotation and get the inherent drift. They also use accelarometers, and computer based integration, to get velocity, and again to get distance, and then can use the ring gyro units to calculate a position, based off of initial conditions. Then you use things like GPS, or star trackers, to obtain the error you have, and use that as part of the drift correction applied. But the modern reference platforms are now so accurate that you have correction both for rotation of the earth, and also for rotation around the sun, and have to apply as well correction for the motion of the solar system around the galaxy core as well, simply because this does otherwise show up as a long term error.
In the 1970's Boeing had inertial reference platforms that were stable enough that you could fly an autopilot based flight without any external correction, and have a single flight from London to Sydney do that flight, and at landing it would be within 100 feet of the true position. 3 separate gyro units in each inertial reference unit, and the logic would fault any single one that disagreed more than the specified amount, and still give a valid reference off the other 2, just with a caution that maintenance was required. 2 inertial units, just in case one failed, and as backup you also had the old standby magnetic compass, and the Decca beacon receiver to allow you to plot location, provided you did not use the wrong lane. Later on GPS with the Decca, until the Decca was finally phased out. But even in the 1990's Decca was still in use a lot, simply because the cost of retrofitting a lot of aircraft was expensive, so it was in use till almost every aircraft had been updated to both, before it eventually was slowly switched off world wide, though there are still a few stations running for some countries.

@TwoBitDaVinci Drilling a deep well will be better energy wise over trying to condense water out of the air. Your dehumidifier can be the house AC system, with condensate water going into your grey water system, but just cooling air to condense water is a massive energy hog. Better to drill down a deep well, get the local (probably polluted with all the industrial waste residue, if you are in an area that has had any heavy industry nearby in the last century) water table, which is stored in the soil from rainfall, and clean and use that. Otherwise you will simply double the energy you will need from solar panels, for only a small amount of water, that will still need to be filtered and cleaned to make it drinkable. Deep well with a pump requires a lot less power per litre of water than any AC condenser can ever achieve, and even with solar power it works out cheaper.
If you want water from air put in a solar distillation unit, to get fresh water from the grey water instead, which will be much more energy advantageous to do.

Flew in them a lot, as well had a nice tour during the Junkers being restored, seeing the aircraft stripped down to near bare metal. With the Dakota, plenty of hours in them, though they were a lot more modern inside, upgraded avionics in most cases, and slightly better canvas seats. With the original P&W engines it was always wise to check for oil dripping out of those oil coolers, because if there was none dripping, there was no oil, and not a good thing. However there are quite a few upgraded to a turboprop arrangement, with much better fuel economy and operating cost, and those are great to fly on. Converse applies there, the oil coolers actually work.
Only one time I was worried flying on one was when we had undercarriage failure, and had to circle till empty before landing, after a few cycles of the gear, with me as the human lifeline holding the flight engineer, as we both were leaning out the door looking if the gear was down ( it was), and it looked like it was locking ( no green light on the pedestal). Best, smoothest, landing ever, though slightly marred by the 45 ton Rosenbaur fire engine that was pacing us down the runway with a running foam cannon. Switch was sticky, percussive maintenance and it was fixed enough to fly us the rest of the way. Got in to my destination 6 hours late, walked in and was asked why, replied the Dakota broke down, and we all had to get out and push.

Yes, impact hard enough to trigger restraint systems, not the airbags, as the system is smart enough to detect the collision angle and direction, so merely fired seat belt tensioners on the occupied seat to keep the driver from flailing around the interior, and then also commanded the ECU to shut off fuel and disable the engine, plus also automatically unlocked all doors as well. So the driver can still turn off the car, and start it again, though there will be a big warning about safety systems faulty, and that service is required, along with a warning about limited performance mode being enabled. Bosch is clever that way.

Funny thing is when I was in you got a sheet for a vehicle with the vehicle, that you were supposed to fill in first thing every day. First parade sheet, where all defects were noted, along with the mileage, and who was the one filling it in. That sheet was ignored by most, but i filled it in every day, as you were doing a walk around of the vehicle, and checking fluids, so you had a good chance to catch things like flat tyres and leaks, along with low oil, before they got to a failure. Tyres and oil no problem, just drive it to the other side of the hanger, and grab a fill lead from the aircraft tyre bay, and oil also no problem, we had plenty of multigrade oil for GSE there as well, so there was always a part bottle with the odd pint or three in it. Could not go off base, but you were free to use it in all equipment on base.

The fob on car works well for metros, who use a particular chain in the area, and thus all the vehicles can simply come in, and fill fuel. At the same time the CCTV also captures both the vehicle details, driver details, and the link also does double duty, with it also transferring info about mileage driven as well, so this all is automatic. The vehicles that either fill up too much, or who do not match the description on file, are all flagged automatically.
I had the same, a tag that worked at the local garage, simple to go there, tap and fill up, no other things, as each driver had the tag linked to them, not the vehicle, but the recon at the end of month would have all data available, so looking up this was easy, just email a query, and it came back a day later complete with images and full data from the pumps themselves.

And then you have to think that the uranium we mine today actually comes from ancient natural reactors partly, and those formed, and the by-products stayed close, so that literally a billion years later, they are still close enough that you can mine the uranium out of Oklo, and find evidence of these old natural reactors around, still where they were originally. no containment, and with water percolating through the rock as well. Most mines where you got the ore out, are good places to place the waste in, seeing as the stuff has been there long already without dispersal. Just fill it up, close off and leave it, and in a couple of centuries come back and mine it again.

Well simply because they are rare, and there are not exactly a million cameras on Mars capturing video 24/7/365, only the odd camera on a spacecraft that orbits, taking a complete pass every few days for the low resolution, and every few weeks to months for the higher resolution imagers, simply because they are scanning with such a small aperture camera to get that increased resolution. 99.999% of the meteorites that hit earth smaller than 20kg are not recorded either, simply because they burn up out of view, or nobody looks at the footage, and only the bigger pieces actually make it down and leave any mark, so likely 99.99% also are never going to be found either. Big planet, small rock, and nobody knows when or where one will hit.

@consaka1 Basically a specially machined bolt and nut, with 2 ends, where one end is the minimum size for that particular thread diameter and pitch, used to check the thread is not oversize, and is the go size, in that it must fit without binding, and must be firm with no wobble. The other side is cut to the maximum diameter, at least just past the first few turns, and should engage a turn or so, so that you are sure the thread is not oversize as it stops going in. For the nuts the first is the maximum diameter, and all bolts should fit with no slop, and the other side is the minimum, and it should not go onto the bolt after the first turn or so.
Unfortunately precision parts, and you need one of each double ended tool, per fastener pitch and diameter, so these are not common, normally used only for very close tolerance work where you are running the fasteners at a very close tolerance and at a very high loading. you normally see them in aviation maintenance, where they are used when rebuilding airframe and engines, to determine whether a fastener, which is normally an expensive part, as the cheap (under $5 each) fasteners are simply regarded as a part you throw away each time. These are for the more expensive ones, where you will use the gauge to check the fastener, and the hole, are still within tolerance, so as to allow them to be reused. $500 gauge, used to check a $1000 plus bolt, and the gauge itself has to be calibrated and certified annually, or more often, depending on use. Half of an aircraft repair facility toolbox is special measuring tools, so they use a Snap On toolbox, as that is often the cheapest single part in that tool box. Spanners have serial numbers in a lot of cases.

Probably will go back to the tallboy concept, drop next to the bunker, penetrate deep into the ground, then detonate, and the cavity formed will damage the bunker so severely it is unusable. Collapse the entry and exit points that way and even the hard bunker is useless.
Or we will be seeing mach 5 capable bombs, that are dropped from altitude with rocket assist, so they will penetrate deep before exploding under the bunkers, having guidance that brings them in at an angle to detonate under the bunker, as likely the floors are not as thick, and thus the blast will reflect off the roof, destroying all in the cavity.

@CuttingEdgeEngineering I was expecting at least half those exhaust bolts to need the sparkle spanner, but they all actually came off. Keep that water pipe, it likely is a lot better than the OEM one, and for sure is much better put together than the OEM one. BYW, great work on those throw away welds on the nut, each one came out looking perfect, even though both were destined to be in the scrap bin 30 seconds after they were cooled down. As you have the base of the bolt available I would have first tried putting a nut and lock nut on the bottom of the thread, and taking it out that way, less thread to engage, and also the galled section will be easy to move in the same direction. One of the times a plain drill would work to drive it out as well, just drill it, and it will probably have zipped right down after 10 seconds.

@brandontyler1754 Please come visit me, where the US jail system is looked upon as really cushy, or even just go to a place like Philippines or Mexico, and get a parking ticket there that you do not pay. There are plenty of times you can get tossed in jail and stay there for almost no reason, say you are travelling, get into an accident, and lose your wallet, phone and all ID, then you are in a hospital with no way to connect to any friends, and they toss you in jail because you have no money. Then you stay there, because you have no way to pay, and no way to get anybody to bail you out.
The hospital wants money, you have for some reason no way to contact anybody (no ID, forgot all numbers, all numbers are in phone)and the jailer will simply keep you there till a court date, which might be in a week or three. Your description matches vaguely somebody wanted, so they keep you inside till you are identified some way or the other. Even worse is that plenty of places you are guilty, because you are driving while being the wrong colour, or the wrong sex, or the wrong religion, or you had "too much cash" on you, so it all was confiscated as well.

@ProjectFarm My cheapest ones were actually US standard sizes, they had not moved off the shelves for 40 years, since the country went metric, so were finally on sale, for only double of the price in 1970, so I picked all of them they had up. Only 3 sets, but covered all the US standard sizes I used on US built machinery, 1/4, 5/8 and 7/16 standard thread. Also got the 7/16 die nut, so I could make the shear pins that used that thread, instead of ordering them, at a ruinous price. 1metre of 12mm stainless steel hex stock made a large number of those shear pins for use. Machining the pins, plus the tooling, came to the cost of only 1 pin, and I got over 20 of them, with bar left over.

Fails when hot, my perennial Ford issue, so much so that in the vehicle there was always a distributor module, tested for a few days, a 7mm spanner, and the thermal transfer compound, all wrapped up in a cloth. Those were all aftermarket, simply because Ford/Mazda did not supply them any more, and even the OEM one was notorious for failing. But a 5 minute job to swap it out, and use the cloth to clean your hands, then go buy a new one to put in place of the spare. At the time they were under $10 each.

I do the same, just make sure the bolt and nut used are 8.8 or better, as plain steel wears badly after a while. With the nut I also try to use a nylock nut so it self grips, so you do not worry about the thread, though I also have done some with red thread locker to keep the nylock there forever. Nylock goes on insert end first, so you first do it regular way to cut the insert to the thread, then off, turn around, and put on the bolt backwards. For those with regular use (M4 and M5) there is a second nylock that acts as jam nut on the one for the insert, firmly pressed down nylon to nylon to deform them, and they do not move, even when used with a power driver.

Case in point Renault, making a vehicle with a 3 year warranty, that would generally have the gearbox fail after 4 years, and making the vehicle scrap. Designed that way, so as to increase sales, as it is easy to make a gearbox that will last, and not cost more. Case in point VW Golf 1, where the gearbox is almost unheard of to break, unless you either ran it without oil, or dropped the clutch at every light at 5000RPM, and even then the CV joints were more likely to snap first. Plenty of 40 plus year old ones still running around on the original box, might be rust in close formation, engine smokes more than a coal plant, but still running around.

@stephendrake8145 Insurer will often sell it back to you for less than the settlement, generally using the tables of scrap values they have, as that is what they would get for it anyway. Write the car off, and insurer has a list of what they got on the last year on auction per make and model, for those wrecks, and that is used for the year for buy backs. Often an insurer will total a vehicle for minor damage, especially vehicles with notoriously long lead times on parts, or where they need to use single OEM repair centers, so if the projected repair is more than 3 months out, and you have a rental clause in the policy, they will likely total it if not driveable. You can think of which one has the most totalled vehicles because of this, and it is basically a camera and computer with wheels. Plus a few dedicated YT channels as well.

@BriBCG Well, a university, with a whole facility generator, or at least a generator to power critical systems, will have a breaker box dedicated to this system ,and plugs dedicated to it all over. Thus you can plug equipment into the outlet, and it will have backup power for it, if the main power goes out. Either a battery bank and inverter for the few seconds till the generator powers up and comes on line, or it will have 15 seconds of no power, a good enough compromise for a lot of systems, who can tolerate 5 minutes of no power. This will be a separate breaker, and a colour coded plug, which in hospitals and such you normally find white outlets for regular power, a green one for patient care with generator back up, and a red one for IT equipment with both battery and generator back up. 3 separate breaker panels per area to supply them, normally next to each other, and normally just closed, or locked with a lock, and a break glass panel next to them with a key, in case of emergency.
Cleaner went to the box, and turned off the breakers, till the noise stopped. That was a deliberate act, not an accident, and they knew it was gonig to turn off the equipment, because the plug and outlet were locked out, and had a sign on them. That action shows they did this with deliberation, and the company should have trained the staff better, not just hired you because you had a heartbeat, could make a cross on the paperwork, and vaguely knew which end of a mop was the one to use on the floor.

@Fydron They were the first to have collapsible steering columns, and as the steering axle is below the driver the shaft actually is an impact absorbing member. Designed to fit a space envelope, and have maximum cargo space, so yes there are compromises. Also mostly used for short distance movement in a city, where you have many starts and stops, and lots of times you load and offload, which they are perfect for. The passenger versions are very common as taxi's, as you can get 6 people plus luggage in with no problem, and if no luggage 9 plus the driver as well, with some work.
Had one at work, nicknamed the half loaf, and it fitted 10 including the driver, and went around the clock at least twice, with just regular service, and lots of brake pads and disks, seeing as it went up and down a mountain pass every day.

Exactly, your value can even depend on the street address, so some builders put the main entrance on a corner lot on the cheaper side, even though there was more frontage on the main street. Some small malls are like that by me, cheaper to have a side street entrance over a main road entrance, even though the longest length is main road, but they put parking there, as that section, barriered off by a small kerb, is technically city property so was not allowed to be built on. Side entrance, and tar is allowed though.

Telco companies make bank off robocalls, as this in their eyes is free money, even unanswered calls, or calls to voice, are generating income. Scammers regard the money they pay as a business expense, something to get from the ones who fall for the scheme, or they run the scam out of a legit call centre where some other company (often the same phone company outsourcing their call centre there) is paying for the building and call volume, and often even the call agents as well, so it is sheer profit.
Telco has this income, and lobbies hard to keep this income stream going, as after all, like the Post Office, junk mail is a good part of the income stream.

Alternator can recharge the battery on idle, providing there is little load, so lights off, no blower fan running and no AC, no heated seats, no demister on and no radio on, so that all the limited power the alternator can deliver goes into charging the battery. Easy though to have more load than the alternator can do at idle, so best is yes to drive for a half hour to do something else, so that you both have engine RPM up higher, and thus more power available to charge, and also are not wasting fuel along with diluting the oil with blow by.

Having come close to clocking one, yes that is a good thing. though that was the least worry of that night, further on came across a hippo, and definitely did not want to be involved with that. Emergency stop, and a very rapid reverse, because a hippo is quite capable of biting thorugh sheet metal of a car, or even biting through the radiator as well. Hitting not good either, 2 tons plus of by now very unhappy critter sitting on your lap, and they are, despite the massive bulk, both very fast and very agile. Elephants give them a wide berth, along with rhinos, and crocodiles, and all of those are very capable of defending themselves.

During Covid I went nearly 6 months with expired registration, till I got a chance to go to the one place that was open to do business vehicles. Did mine the same time, only 6 months expired, and I got another 6 months free with no penalties. Drivers renewal I just drove for 4 months, with both expired card and receipt, but being the traffic police are more worried about parking tickets and eating fast food, over actually pulling vehicles over, nothing to worry about.
Now things are sort of back to normal they are clubbing you when you drive in to renew either, as the parking lot by the license area is classed as a public road. So did have to drive my friend in to do his renewal, as his was a few weeks expired. We went to the most bribe friendly office as well, but sadly did not have to pay the cooldrink fee.

Totally 100% CCCP made, as the same parts, in different grades of quality, were made for the military, and thus the consumer and industrial equipment used the lower grade parts, and after they started doing commercial production they simply kept on making the same parts, using the same machinery. USSR tech was always on the trailing edge in a lot of respects, as they had to both make the machines first, and then were loath to upgrade them to make newer versions. Some parts were utter junk though, especially capacitors, where they routinely used parts designed in the 1930's, when much more modern parts existed, but because the machinery was still working they made the old ones, despite them being shorter lived, and also making poorer quality parts. Got some old Soviet era metal can capacitors that are identical to the 1940's versions, but made 50 years later, and they are as unreliable as the originals were, degrading even when not used. westerm made units updated over the years, to make them much more reliable, and in many cases closer tolerance and better performing at the same time, and also improved material made them much lighter and smaller.

As it takes a few months to renew anyway, I simply went a week before expiry, and did the renewal, then drove around with the expired one, and the receipt of application, as the card expires, not the actual drivers license. Never got pulled over anyway, last time was years ago, pulled over, showed them the card, and went on my way.

Oh yes, please remember to get your shop a Recoil/ Helicoil set, with a pack of 50 M6x1mm by 1.5 length inserts, because you will be needing it for the Rubasoo timing belt covers, as those little M6 bolts get stripped out by the dealerships going in with the ugga dugga method, and tear the threads loose. Done a good number of Recoil inserts into either aluminium alloy valve covers, or on VW carburettors, where the centre bolt comes stripped, and there is only room to do the Recoil insert. Drill down deep, and put in 2 of the 6mm inserts, to get enough thread engagement to keep it from stripping out, and clean the hole, plus use green oil resistant threadlock on both insert and the stud.

Fujitsu said Horizon was incapable of error, but admitted it made errors always, and this led to a good number of people dying after being accused of theft, and a lot going to prison, despite the prosecutors from the Post office knowing the software did make errors all the time, and that it would regularly fail.
Using old photos, and poor photos, will cause errors, the old adage of garbage in garbage out is true, you cannot extrapolate a face form a 5 by 5 block of grainy pixels, and expect a perfect match. You will get thousands of 90% plus matches, and likely half will be the wrong sex, and 80% of the rest otherwise wrong. The 10% left likely the first name that came up, that lived there at some time, they put in the line up, and went for the arrest warrant, without any other checks.

Because the manufacturer gets one fewer oil change they are required to do under warranty, and they also know the vehicle will be traded in at a big discount for a new one, right at that time, so will be either exported or scrapped. Export it likely will fail soon after, but again not the manufacturer problem, out of warranty, and then they get to sell a new engine. The less oil changes in warranty the lower total cost of ownership they can prove, so they will go for 20 000km or 25 000km soon, knowing full well the engines will self destruct typically at around 200 000km, outside of warranty, which is typically 120 000km or 5 years by me, though some only are 80 000km or 3 years for some models. Only manufacturer that offered a 1 million km 12 year warranty is Chery, on the top range hybrids, wonder how that is going to turn out.

2 mile radius is to keep ships and drunk boaters far away, the exclusion zone allows enough time for CG cutter to intercept before they are in the danger zone.
Beam swinging was building up plastic deformation, and then as the steel cooled it finally fractured. The explosives are pretty inert until they put the detonators in, and likely here they are using coded detonators, which do not go off from stray currents, but which are addressed like stage lights, so they are all powered, and get sent a time delay command. Safer than a detcord as it can be tested for each charge right up to detonation, though a lot more expensive, and use once. But even with 5% failing that will still be successful in removing that beam structure, and then they can use larger charges to fracture the concrete after drilling into it to place them, or drill and use expanding mortar to fracture the concrete, so the claw and hammers can nibble it away.

@WN_Byers Pilots hours start at the pre flight briefing. A delay means they potentially can run out of flying hours for the day, and thus will have to be put up in a hotel for the night, to get the mandated rest period to reset that flight clock. A 5 hour delay, on a flight that might be another 5 hours, will definitely mean there will need to be a relief crew, and if there are multiple stops with the same crew they will run out of hours before completing, and have to have mandatory rest period.
But if maintenance says this is a 20 minute fix, they will board, and wait, but the second it was past the 1 hour mark, with no indication it was going to be done in the given time, they should have returned to gate, or deplaned and returned to terminal all passengers. But not wanting to have the 30 minute delay to get all on board again is powerful motive to keep you on the ground in the plane.

Another issue with spices is they also react with medication, not surprising, as many medicines are originally extracts of plant matter, and many are still available as a common spice, like cinnamon, a tree bark, and nutmeg, a tree nut, both of which have medicinal uses. Thus spices are very limited in use, along with needing to have a low controlled dose of salt, for those with renal impairment or those with unknown renal failure or hypertension, which means the food is generally lacking in salt to enhance flavour.

@bobbykozak6032 Works well, and braze adheres to cast iron well if it is clean, and you use a decent flux. Yes it will melt if the exhaust gets hot enough, but running a cast manifold at red heat is already a serious fault in the engine.
Did see that once on an Atlantis diesel, we guessed that truck, with the coolest part of the exhaust being the tip at dull red, with some really nice Mach diamonds, would not make it to the top of the hill. Turbo was white hot, bright enough to actually cast a shadow in the twilight, and was visible to us from 2km away as a bright light. Engine was breathing well, and no shortage of fuel either, though that turbo was likely also acting like a combustion chamber of engine oil.

Thinknig that the pump could have been killed off by bad fuel, which sent the marginal pump out to pasture. With what came out the filter you probably had a nasty sludge build up that made the pump work hard, and finally die. high pressure at inlet, yet the engine side with barely anything, filter was clogged badly, and then this let the pump work to build up too high a pressure, which eventually caused it to fail, either shedding bits of the impeller, or by the high current draw against the high head, eventually heating up the rotor to make one of the segments go open circuit, not helped by the low flow making it boil the fuel in there as well, which then leads to cavitation, and the hard starting till it cools.

@DrDeuteron True, but the decay products are not quite as benign after a while, as you get into the longer lived decay products, that are going to emit gamma radiation at some level. But the RTG would only have the core loaded just before final mating to the lift vehicle, so it is inert, aside from some testing during construction, then the fuel pellets are removed and placed in a cooling unit. But even then you can stand next to it for a few hours, as the shielding is very effective, and it also has to survive reentry at maximum velocity in case of a failure of the launch vehicle, and also explosion on the pad. That is why those RTG units are normally deployed on an arm, both for radiating heat away, and to keep the low levels they emit from interfering with other instruments, so have it far away, and calibrate it out.

Well yes, the currents involved are minuscule, and the price really puts them in the "we got a budget that is not a worry, and we do not want a battery that will leak ever" camp, and the main use is as memory back up, as it really can only supply 100nA of current, so most uses are as standby power source for memory back up, where you need to first make sure your memory uses less power. Consider these batteries in the forms normally seen, DIP24 ceramic package, can be shorted out merely by a fingerprint on the board allowing enough current to flow, and you typically also use ultra low leakage capacitors (PTFE dielectric, none of that rubbish ceramic, electrolytic or tantalum capacitor will do) to store charge to allow them to deliver a current pulse for other applications.
Yes you can make a clock that will run forever off them, though you will find it hard to find a foundry to make the large dimension IC to get low leakage, and a display will similarly have to be specially made, probably both will be a SOS (silicon on sapphire) structure, with the LCD laser sealed after filling with the fluid, to keep it from degrading. Might be done for a $500k watch, because for sure the mech will cost more than making the case out of platinum iridium alloy.

One building down the road from me was built, but not all the units sold, due to the price and the monthly levies. So now more than half of them are now on rental as AirBNB, still owned by the developer, and likely to stay that way for a long time. Not a bad block, but when you are paying the same as similar 80-100 square area units, with 2 bedrooms and parking, for a 40 square metre bachelor, and parking is also an extra, plus the monthly levies are pretty much 5 times the average. So many are literally unfinished, just windows, bare primer walls, and subfloor, with nothing other than service pipes and power as stubs.

@bwhgs2 I run based on what you see still running with zero maintenance by me. Street lights from 2010, only a few original ones still alive, if you consider at least half the LED units are dead, the rest still light up. As to the rest shortest life was a week, and they all got changed out after a year, with the replacements lasting typically 6 to 9 months. Phillips fittings, not the cheapest, but they get killed by the heat and poor power quality, while the HPS units only fail from MVA and when the fixture rusts apart and falls out. The SOX and SLI ran since the 1980's with zero maintenance, and only got replaced with HPS when the rail yard was cut in half to build a stadium, where the stadium high pole lights did double duty and lit the track as well. Built for 2010 World cup, and still has original lighting on them. Yes might only have 3 of the 6 400W HPS still working, or less.

Labour cost, and not many places around any more that will recondition an engine and block. Cheaper to drop the engine out and bolt in another than strip the head off, send out to be skimmed, do the valves, clean off the block ,check block is still straight, get head back, and install again with new gasket on it. Especially US rates, though take it across the southern border, and the price to do that is halved, due to the lower cost of labour.

@TwoBitDaVinci It uses the magnet inside the meter that is rotated by the positive displacement pump in the meter. The pump turns one roatation for ever so much volume of water that goes through, and then this is divided down by a gear train to drive a rotating flag, blue on your meter, red on others, that turns the main gearing of the totaliser. The flag typically rotates 10, or some whole number, of revolutions per gallon of water. Here by me the metric meter is 200 revolutions per kilolitre (1000 litres, roughly 285 gallons US) on most meters. Sensed by either a reed switch or a hall sensor, outside the case, there for smart meter use, and then sent via the wireless link to some server, to update your account every few minutes as to water use.

@-Gorby- Reaction time of around a second, and another second to move the foot from go to whoa pedal, then probably a half second before it was all the way to the floor, though I will bet the SRS system data recording will show that pedal application was slow, and only went to full just before the SRS trigger even was recorded, and then after that the data showed full application, along with lots of yaw data as the car was spun by the impact, followed by a second hard impact, then just stopped data with the engine ECU having done an emergency shutdown and fuel system disable, along with body module releasing door locks, and activating flashers, then end of data. Most record 30 second before and 30 seconds after, only writing it into permanent memory instead of RAM if there is a SRS trigger, though you can with OEM tools read the last few minutes, if power has not been lost, in many cases.
It will record peak speeds for last drive cycle, highest speed measured with time and date, and if telematics is connected, that will also be on the manufacturers storage, along with all driving info since the vehicle was first powered on, along with location and direction, plus any engine warnings as well, and brake events.

Lightning always best to have external lightning protection in the breaker panel, then add in surge arrestors in the outlets that feed the UPS. For lightning you need multiple stages of clamping, high power but high standoff at the power input, that can handle the high energy incoming surge, and attenuate it down to a lower, but still very high level, surge on the power to the breaker panel. Then the breaker panel unit will reduce it further, using the impedance of the wire from the meter to the panel, and ensure a lower level to the outlets. Then the outlet units can handle the lower level surge, and clamp to a safe voltage for the equipment. Then the UPS can handle this higher voltage without problem.
Remember the lightning protection starts at the power line, with power companies using lots of surge arrestors and arc gaps along the power lines, because they all run outdoors, and are often the highest point on the landscape, and all the pylons are well grounded, so all of them will receive multiple hits in a storm. Thus there is a lot of protection, to limit the spikes that go to the customer side, where local hits cause a lot more damage, simply because the surge clamp ability is smaller there, as the power levels are lower, so the utility sizes them smaller. But also local lines tend to be hit less, as many are not that high, and are often buried as well.

@CuttingEdgeEngineering Yes, never seen that use before. Have done the bronze plate though, to fix up bores that were somewhat less than good, to get them to the point the shafting that ran in them, or at least the new shoulder bolts I used, would be a tight fit. Holes wallowed out, and the original pins were under 5mm diameter at the wear points. No way to get spare parts, seeing as the manufacturer, still in business, no longer supports a machine they made in the 1970's, and have less than a clue, though the parts likely are still on some of the modern versions, seeing as they likely use a similar version of the linkage. But the braze and drill was both faster and cheaper, and the shoulder bolt was $3, off the shelf. Now to get some flexible pneumatic cylinder shaft couplers for it.

@JoeOvercoat Civilian aircraft cannot do inverted flight for long, only under around 10 seconds, before the fuel starvation stops the engines. Fighter aircraft have a fuel tank within the final feed tank, which allows inverted operation for a period of around 30 seconds at full afterburner, before it will start to run low. Yes it will gravity feed fuel to the LP pump, but after there it is pressurised, and fuel transfer from tank to tank in the airframe is done by pumps, generally self priming gear pumps, because the fuel in drop tanks, always below the fuselage, is always used first, so it has to be sucked up to the main fuel tanks, with overflow returning to the drop tanks till empty, then the shut off valves will stop that, along with the pumps.
Lose the pumps and the engine stops in short order.

Like the genuine Hoover we had, made in the UK around 1930, but they were unable to tell when, because the records pre 1940 were destroyed in the Blitz. But still we could get genuine Hoover parts for it, till finally the main casting cracked, and there were no more spare castings available in the 1980's, and it went to scrap metal. But every other part, from the motor, the mains cord, to the power switch, to the screws that held it together, were available off the shelf from Hoover, including rubber belts, rubber bumpers and handles. New ones you are lucky if they last the warranty plus a month, and if they still suck after 6 months, without stripping them to remove the dust from everywhere that clogs them. Yes i collect old tossed out vacuum cleaners, often for use as spare parts to fix others.

The reset, NMI and interrupt locations are the marked addresses, but the program counter is simply set to that value, leaving all registers and flags as is, and it then executes that address as if it were a regular program location. Thus you would always store in that location a jump instruction, followed by an address elsewhere into the ROM, which actually has the right code you want to execute, and thus, aside from reset, which also clears all internal CPU registers and flags, you get the code to run from that new location, with the stack in page 0 containing the address of the last instruction before the interrupt or NMI was asserted.
So after your code executed for int or nmi, you simply made sure you had restored all flags, and popped off the stack correctly, leaving it at the right address, and issued a Return from interrupt, which popped the stack back to the program counter, and the program would execute from the next instruction, totally unaware of interrupts. However the 6502 does not store flags in the stack, it is up to the programmer to first disable interrupts, to prevent another from dropping you off into lala land, then take the flags, and save them, and all registers you are going to use, into the stack, before doing your hopefully very short and very fast interrupt routine. Then on the end you restore all those registers, and flags, and finally, before you execute the return from interrupt, you enable interrupts again.
Luckily for the programmer the 6502 interrupt pins are edge triggered, so if the pin is still asserted you will not get another interrupt till the pin toggles inactive and then active again. This is sampled as well by logic that only will assert it when there is an opcode fetch, not in the middle of an instruction. NMI is not so lucky, use with care, as there you can go out, as by definition you cannot mask a NMI event, though it does use the same logic for selection. Rest is the hard one, it simply uses the internal logic to force set all flags, stops the internal clocks from operating, forces all the address and data lines to the tri state condition, and same for all the control lines as well. Plus on the transition to logic low there is a small state machine that turns on the internal clocks first for a few cycles, then deasserts all the forced reset of registers, before enabling all the bus and control lines, before finally releasing the program counter from being frozen, with the pattern for the reset vector set into it from the logic, as that hard reset along with the interrupts is coded into this state machine.
Been a while since I looked at the 6502 datasheet, and the errata for the later versions, alongside the early ones, have some instructions that were there, but later on got marked as do not use, dimply because there were some that did not work correctly on the early silicon, or which were as a result of a simple decode logic that had some that could work with multiple opcodes to do the same function. Those were used to tell early chips apart, as some would work, others would hang, and some did unexpected operations, generally needing you to press reset to gain control back.

@CuttingEdgeEngineering I will guess mostly on his back in muddy water, upside down to his mouth in dirty acid laden mine water, welding plates onto a machine so it can "finish this shift/week.month/year before we do a proper rebuild", and the welds has to last till then, and then some, because it would never be done, and he was laying patch over patch over patch of his.
Just like my late neighbour, welding patches over active leaks in the paper plant, because to shut it down you had to wait till the 3 month window for overhaul, and the stainless steel pulp feeder would be a mess of patch over patch by that time, because paper pulp is incredibly abrasive. 3 month life for the 3mm stainless steel plate, before you started running patches, the titanium alloy version he made lasted 9 months before they had to lay on the stainless steel patches. Pretty much replace the pulp side every year during maintenance window, and you had to build the chute in place, because it would not otherwise get in there. not sure if they stayed with the titanium, because of the price, and he stayed on for 10 years after retirement to train 3 people how to join paper webs. Only way you could see his joins was the colour of the mesh from the silver solder, otherwise it was identical in appearance to the rest, so it would not leave a mark in the paper. Each 0.5mm wire bevelled, brazed and cleaned down, across the whole width of the web. Not bad for an ex POW from Italy, who got interned in SA during the war, and who never went back to Italy, but instead built bridges, and became a machinist and sheet metal worker at paper plant for decades.

For those saying grinding off the side weakens it it might be true, but a wheel stud is one of the more over engineered parts of a vehicle. That 5 stud pattern is designed so that even 2 adjacent studs being in will still allow the vehicle to safely drive, and not fail for a good time, and thus with all 5 in they run at a very low stress anyway. More likely to snap off from being put on by Bubba, and his 12 foot long cheater bar, shearing off the threads at the end of the nut, than from pulling the stud through the hole when the lip shears off. Or simply having the threads strip off of a well worn stud because there is only a half thread engagement to the thread on the nut.
By me it is so common to see a 3.5 ton Quantum minibus taxi, loaded with 25 plus people, driving at high speed, when you look at the taxi at the rank, and see it has 10 lug nuts shared among the 4 wheels to hold them on, and one will have all 5 still there. Yes common to have the wheels come off them (have been the recipient of that twice), but generally that is because the bearings have long gone out as metal powder, and you get a wheel, brake drum and backing plate, plus half shaft, come off as a unit. Same for buses, though there is is 30 out of 40 nuts, with the broken ones still there in the hub.

@solandri69 Most likely poor maintenance, they painted over the cables time and again, and you will probably find they trapped water in the cable, which led to corrosion cells and failure. The cables likely were made from hot dipped galvanised strands, which eventually had the zinc erode off, exposing enough steel to make galvanic cells inside the cable.
I would say the design flaw was not in having enough cables there, so that you could safely remove half of them every 5 years per tower to replace with a spare set, and those removed went off to be unwound, serviced and inspected, and then greased, reassembled and recoated for the next tower rope cycle. 10 years would be plenty of time to find weak strands and remove them. Yes you would probably be splicing in repair sections every time, making the cable thicker in parts, but they would still be more than capable with that. That the initial cable failed at the poured zinc plug indicates it was very likely badly corroded inside from neglect, as that section is the one most protected cathodically, but had plenty of water ingress to corrode the inner. Likely all the lanolin applied during manufacture was long gone, and had never been replaced.
Not that those were highly stressed cables, only a static load, no real dynamic force and no real bending. There are mine lift cables that are kilometers long, used dozens of times daily, that are probably older than those, but they also undergo regular inspection and lubrication cycles to keep them in operation. There are plenty that the cable weighs more than the entire telescope aerial steel structure, just in the cable alone.

Varies from state to state, many do not even require a roadworthy when buying a vehicle, or even an annual check for fitness to operate. Also varies from country to country as well, many do not require insurance, and then the insurance you claim from your insurance, they pay out then claim back from the other motorist's insurance, or from the other motorist themselves. Really only in the USA is uninsured other party insurance a thing. Here by me all policies come with a high coverage for other party damage, which will cover the damage in most cases, unless you hit a supercar, or total 3 Teslas in a single accident, where you are completely at fault.

Thing is that silver is not often used industrially, but catalytic converters, and the metals in the ceramic cores, are used in industry in massive amounts, not only in cars, but in pretty much every chemical plant to do processing. Thus a demand that keeps on growing, and keeps the price high, as they are not the most common material, and mining them means you are getting less than 1g of them out of 2 tons of ore, and to get those 2 tons of ore you might have to move 100 tons of rock to expose it, or dig down 2km into the ground. Copper gold and platinum mines all are very similar, in all produce either copper, gold or platinum as the major product, but the other 2 are also recovered as well.
PGM is used as industrial resource, not like gold and silver where it is mostly a bullion reserve.

@SyntheticFuture That old lead likely had signifigant amounts of silver and zinc in it as contaminant, which will enable fusion. Modern lead is likely contaminated with things like Antimony, Calcium and Cadmium, all there to make the lead slightly harder and thus more rigid, which is added to make it more suitable for the largest use of lead, in modern car batteries, which need a durable thin grid that will not degrade, so they can up capacity and lower the amount of lead not in active plate material. The silver and zinc are stripped out in production, as valuable by products, then the other materials are added.
The lead they have likely is from recycled batteries, they need either old lead off a roof, at least a century old, or to go to a mine and get a few kilograms of ore, refine it and get a lead that matches 200 year old lead. Probably needing to have a higher silver content in it , along with a little copper, zinc and tin added as well, which are all things that are present in roughly refined lead. A few kilograms of Galena, plus a silver coin and a few zinc pennies, will probably make a nice soft alloy, that will both cast well, have a good finish, and also stick together on impact.

Put on the sign the full court transcript, and in big print on top the damages awarded. After all nothing stopping you from publishing a copyright free, public access allowed, court document. That it is on a 30 foot high 80 foot long billboard, with lights to illuminate it at night, is your allowed decision, and right, so long as you follow local laws around erection of a billboard, and the local council approves it. Inn really cannot deny this, as otherwise you just hand out copies to every vehicle that pass by for the next year or three, looking to go to the inn.

Common in smaller units, it is around a third of the price cheaper, though I change them to double pole ones when replacing them, even though I live in a country with 230VAC mains, as the double pole unit as a spare part means you only need to keep one to cover both use cases, and then a second 3 phase unit for bigger units that run on 3 phase, where you have a 4 pole unit typically, with 1 pole also used to power the single phase cooling fan separately. Double pole means less issues with tripping when the wiring outside gets wet, as you typically will have the unit hard wired, and thus simply turning it off will allow you to fault find and isolate the unit. Plus compressors often fail as a short to ground, with split phase the unit might keep on running at part power, till the motor itself burns out the wiring.

@TimothyWelty Yes but might be the only way they can do it. I remember one where a tow company illegally towed a car, and had to pay for a rebuild at a specialist coachbuilder, with a 5 year waiting list. Did not turn out well for the tow company. Same applies here, the rebuild might be the only option, along with the damages as well, for treble the cost of the rebuild, which they will have no option to pay either, and also find that insurance will not cover it either. Claim rejected because part of the drop off was explicit instructions not to leave the lot at all, and thus the dealership, along with those 2, are fully on the hook for all damages.

Often HOA is the only thing available in an area. The city loves them because the city gets rates money from the houses, but does not need to spend a cent on maintenance of streets, power, water, lighting, garbage collection or general maintenance, and the property pays rates but gets nothing back, and in turn the residents pay again for the services the city should supply. All new developments are HOA, nothing is single house any more, unless you look for the odd house not in a HOA, which will demand top price precisely because of that, even if it an old house. Might be next to the HOA, but not bounded to the rules, and thus the selling price probably will be 20% more than the HOA ones, because of this freedom.

Will tell you that those big box stores order their appliances with a different part number and brand printed on it, just so they can offer to price match, knowing full well that they are the only one with that exact model number, even if the shop next door has the identical, down to the witness marks from the machines used to make it, device, just with a different model number and brand. Also they cut costs on them, swapping out say a metal bushing for a plastic one, knowing it will wear out in 13 months, and you will buy a new machine, instead of replacing a 10c plastic bushing.

My father had a neighbour, who used to do fabrication at a paper mill, and his speciality was brazing the paper webs to make a continuous roll. Only way you could see the joint was to look for the line of yellow and blue on the shiny fine mesh stainless, where the heat had discoloured it, and the yellow was the silver brass alloy paste he used, to join the individual 0.5mm wires together.
Did that for over 40 years there, and even in his retirement he would go in and do this, on a contract basis, well into his late 70's. He did train a lot of people in the job, though most of them left after a few years for better pay, so he was always doing the training, and also some specialist fabrication when needed.
Don't think I could get to that level, I do not weld enough, and can do reasonably strong and ugly though. Filler and paint though can cover a lot of sins, and car body panels are not at all difficult to replace.

Laws by me were amended for home auctions, in that the minimum price for the auction reserve is set to a large percentage of the fair value of the property, determined by at least 3 separate agents in the area. Also the owner is entitled to any excess monies left over, and these cannot be used to pay any other parties other than the one in the suit. So if you owe the municipality $x, and your home goes for $500x, you get, after the fees, $498x, and any other claimants have to go after the old owner to get paid, not simply attach to the auction with a note. Done after a string of foreclosures, where fully paid off houses were auctioned off for $100 or less, and went to a new buyer before even going on auction. thus also you see in the auction notices the following "the acting sheriff for x city section, the sheriff for y city section and z city section" where the previous ones are currently disbarred and serving time for fraud.

@EudesRJ Saw a fluke 77 the council arctricians attempted to measure the voltage on the primary side of a transformer, and applied 11kV AC to the input side. Meter stopped working, and the inside of the case was nicely coated with a thin film of copper, evaporated from all the PCB traces on the board of the meter below the display. Display still worked, placed in another meter to test, as that one had a cracked display, from the same group of low IQ techs, and the 9V battery was also placed there, and was fine. 11A fuse was the only intact fuse, the other 440mA fuse got blown, with the rest of the carnage, as the plasma arced through the inside of the case. However nothing escaped blast wise, very tough cases they have. Meter leads were a lot shorter from the arc as they got close, well cooked and in any case they had already broken the probes off, using the bare cores of the wire instead.

Not likely with the currents by the South African coast and the typical routes ships used. If close inshore to use the northern flowing current to get cooler water they go north, and further out to sea the great gyre will eventually land them on the Australian coast, or north again when it makes a full turn. No, it went down off the coast, one of hundreds of wrecks littering the southern African coastline, and hard to find on that large area of ocean floor, that even today is not well mapped, though there are plenty of mappings that have been done for exploration for oil and gas, but actual side scan sonar mappings not much, though you have a fairly good gravitational mapping, but they are low resolution, so wrecks do not show up at all on them. Even wrecks that have actual positions known are hard to find.

When you opened the box, and I saw the thick plywood, proper box with metal corners, and then the heavy strap holding it, in addition to screws, that is a company that wants only the best product. Very good qality, and it should hold up well with the loading you place on it, and seems to have large holding faces all round to not have issues.
Probably just by cleaning and setting up your cross slide again, you have improved repeatability a bit as well, just from getting all the wear out, and fresh lubricant in the system as well.
Guess the rainy season in your area is around, seeing the background was all rain on a hot tin roof.

@richardclegg8027 Cape town your route would, depending on the actual interconnect your ISP uses, actually have been around the western coast on a long cable. Then a few hops in South Africa, and off to the UCT servers. My geolocation always comes up as 600km away, in Rivonia Gauteng, and i see yours does as well, so you are meeting an Akamai CDN, or the servers themselves are actually located there, and not at UCT. Big server farm there, who have as selling point that they are very prepared for DR, seeing as they still have power when Eskom does not, and also have a month or more of fuel at any time for the systems to run.

They need to remove all the containers to reduce draft, then they can start to dewater the front compartments that are flooded, likely not going to get all the water out with likely popped hull plates, but at least half way with lots of big pumps will make it more amenable to being pulled out backwards, possibly even with the ship engine in reverse as well to apply power, as it likely is still out of the mud. Not going to be able to run main engine long, likely all the coolant ports are clogged with mud, but even a minute of full power might be enough to pull it out. Otherwise they have to bring a dredger in with suction and pull mud from the other side of the channel, and wait for a high tide, or a spring high, to do the refloat.

Yes jet fuel is a big one, because aircraft do not take a small amount of fuel per flight, and each flight has many tons of fuel on board. Easily 30 tons per flight, and with 5 flights a day per aircraft, that is 150 tons of fuel a day, now multiply by the thousands of flights a day, and you see a 6 day disruption will make for many cancelled flights, and the remaining ones being full to capacity. Then also all rental companies will be out of vehicles as well, from people renting a car to drive, probably a single occupant per vehicle in most cases, making it worse when normal fuel deliveries start and there are no rental cars at airports, or they all are at far flung points and not at hubs.

Had that with a fuel station, where the one pump was faulty, and was bypassing rather badly. Filled up my car, and, due to a blocked breather, I had to fill very slowly. Full tank was a tenth the price, so I paid, then next day phoned the fuel company, spoke to technical, and told them the garage, the pump number, and the fault. Still took them 3 months to fix it, so I filled up at that pump a lot. Garage not losing, the pumps are owned by the fuel company, and I was paying the correct price per unit.
Those pumps can easily be pre-war manufacture, and originally were reading volume in one revolution of the output shaft per pint of fuel, but have long since had the mechanical meter movement, along with the mechanical reading, go digital, replaced with an encoder with 64 slots in it. Done when the price rose above R2 per litre, as the old mechanical gauges could only be set up to R2 per litre, and thus when it went over they needed to be replaced. Interim measure was to simply put a sticker by the price that said "Times two to get correct cash amount" and set the price down to half. Took around 5 years to retrofit all those pumps to electronic readout, though often, if you see them with the front panel open, the old mechanical Tokheim volumetric pump, and mechanical readouts, are still there in the frame, with the cost being the last one it had, and the price being some astronomical amount, as it no longer is being mechanically reset. Digital covers over the old frame.

@Azeazezar Do not think the motherboard chipset will run without RAM, though you can just take the RAM and update the ID chip to have it report that you only have 16M of RAM on the chip, which would allow the PC to boot, though you likely would have to write a custom BIOS, basically making an old 1990's era BIOS run on a modern multicore processor, which would mean having to add in the core operating logic, to set up all the registers on the north and south bridge, to set them up like they need, then start to run the old bios as a direct task on it, and boot from there. Would need an old PCI graphics card, and also a PCIE to PCI adaptor as well, or even ISA and PCIE to ISA adaptor, to allow the VGA routines on the video card ROM to run. After all modern graphibns cards no longer likely support the older VESA standards, though it will be fast.
Did think, when Pentium processors got past the 1GHz mark, that you could actually put a simple program into a ROM, and boot off it, to use that fast bus speed to directly synthsise FM radio carriers, and also the audio modulation, as a dual core could run fast enough to have one core do the DSP to read in audio, and the other core do DDS to generate the RF waveform direct, modulation and all. Just a simple low pass filter on the output needed. 300MHz processors could easily do AM radio as well, with a simple resistor DAC and a latch, with the enable being simply a write to any high order address line. After all, with 32 bits, and only needing 12 for the ROM, you can be very wasteful with address decoding if you need speed, and really only have 4 actual peripherals to interface.

No alignment tool a broom stick works well, or that punch, and a roll of masking tape in an even layer, to build it up. Another tip is, if you are going into the clutch housing for any reason, like a main seal, or gearbox input shaft, is to replace that throw out bearing, unless it is brand new. Any wear on it cheaper to toss it and put a new one, as you already have done the labour.
Should also have taken flywheel off and replaced rear main seal on that engine, they are known to leak as they age, and that one looks like it has never been off from the factory.

@MacoveiVlad Repairs is replacing broken bits with the same. modification might be a new microphone type or connector, for an updated comms system, such that either the original specs no longer apply, or it no longer is usable fully with the original spec system. For a helmet might be an improved noise cancelling microphone that is louder, so there is a need to change gain, or a new lining that is improved somehow, such that they can check which ones of the stock have been upgraded, as it likely is they are not all modified at once, but in batches as they come in for service, or as they come off a particular base. you can have a mod state 2 applied after a 3, because the mod states apply to a different part, done at different times. The numbers are unique to a particular part, for a particular change.

Yes, pharmaceutical grade water is infinitely easier, not so much care particulate wise, more about sterility and just having low dissolved ions in it, and the water used would easily be produced by the first few stages of the semiconductor industry. Big step up from most city water though, even if the plants all use it as feedstock.
Funny enough most bottled water has more dissolved ions than the feed water used to produce it, regular city water, just sent through particle filters, carbon filters and then resin beds to trap ions, and finally UV sterilised, and filtered for particulates again. Then they add in salts, to give it flavour, and bottle it.

@spacechannelfiver Still have a dot matrix printer in a cupboard, though would have to dig out either a USB to parallel adaptor, or the similar serial version, to get it to work. Have the odd spare ribbon or ten for it as well. Only one you still buy new off the shelf is OKI, who sells quite a few every year, and they support parallel, serial or USB out of the box, and also speak around 15 different printer emulations, in addition to the native OKI version. Most commonly emulating an IBM Proprinter II though, seeing as that or Epson FX80 covers almost all dot matrix print operations, and only differ in the graphics characters they will print to give you pretty borders.

I would say the steps are to keep the power input constant during starting, as the power needs of the motor change because of the need for increased slip during the initial power application, and the steps are there to reduce the CPU need for a smooth sweep, as the original designs used lower speed processors, so offloading most of the power control into discrete power steps was needed, so as to not cause excess slip in the motor and thus poor accelleration, and too fast a ramp would result in a motor stalling. thus the constant steps, so that a driver could keep a constant pull away and not run the risk of a stall, which would mean a stop and a slower ramp up again, and a possibility of the motor generating an overcurrent or tacho feedback error. remember this was originally running likely on aZ80 or similar processor, with large parts being done by other processors as well, and the designers had both limited memory and limited performance.
400Hz was running the GTO devices at the high end of the range, as they, for power devices at the time, needed 2 or more same size power switches for each of the 6 legs of the drive, and GTO devices need you to have a very beefy current source and sink, as you need to turn it on fast, so high current at a relatively low voltage of around 5V on the gate, and turn off you need a current about what the device is conducting, and around -10V, to pull the gate off hard and fast enough to switch off. At least this was better than earlier thyristors, where turn off was done using LCR circuits, and a second equally rated thyristor to pull the anode negative for long enough that the first one would be able to turn off, and then the second one, due to the high power resistor providing it with power, would stay on till the first fired again to turn it off. High static current, high power loss, the GTO made this power use so much lower, at the expense of needing 4 isolated relatively high power supplies, 3 for the upper bridge, and the lower one having a common cathode connection. Instead of 500W of power dissipation now down to under 100W at idle. Add this up per axle and the power use becomes considerable, plus higher frequency, and the ability to do regenerative braking with much less processing power, and you can see why they, and now the IGBT, won out.

Difference between wearing and not wearing one is if you want an open coffin viewing, or if you are happy that your coffin will be closed because the hamburger helper in there is all that is left of your head.
Had a bike messenger who worked with me, who was in a good number of accidents. Always wore a helmet, and leathers, and heavy jeans with boots and gloves, and while the helmet and leathers had a fair share of battle scars, and the bikes quite often got new tanks, fairings, handlebars and indicators, you can be sure that out of the carnage Blessing would come out essentially unscathed, just adding a few more marks to his apparel. Bike accidents (including him doing somersaults over cars) did not kill him, TB eventually did.

No manufacturer will put a full size spare in the back, if there is anything there it is a skinny temporary use one, or a pump and a can of fix a flat. Lighter, so that they can meet that EPA mandated mass and then also save an extra 0.001MPG on fuel use, or in this case an extra mile of range on test track cycle.
My car has a full size spare, and my sister got a full size spare for her car as well, as it came with a well for one, just had in it a styrene dummy inner with the jack, spanner and pump, but no spare, cut to reduce mass and cost of manufacture. spare fitted perfectly, and even the dummy fitted in the rear of the tyre. Came in handy when she found one of the myriad potholes that make driving akin to dodgem cars. So thankful my wheels are actually 70 profile, not the more common 50 or less profile, which are basically painted on rubber, and which cause the rim to crack or buckle, and the tyre itself to be destroyed.

Also had that, a cheque that had already been processed by the bank was intercepted somewhere, and then "washed", in that the only thing left on the cheque was the MCR ink, and the signature. Then the entire cheque was reprinted, complete with background, and then taken and cashed at a branch. The forgery was pretty good, until you looked under a microscope, and saw that the pale yellow background was not a Pantone colour printed with a screen, but an inkjet printer print, with the yellow dots and the odd cyan and magenta dots to shift the colour to match, and then the rest of the information was printed again. Biggest thing was that they printed the wrong cheque printing company, as we used custom order cheques in a self carboning book, printed not by the main print company for that bank, but by a local company that also did the custom cheques for this bank.
Also we had, as part of the record of the book, the folio copy, with the original details there on the carbon copy, and, coincidentally, a spoiled cheque on the same page of 4, which had been crossed out, and written cancelled, by the book keeper as well. Original was for a large amount, the washed one was slightly smaller amount, and offered around 9 months after the original had been processed, and the bank accepted it, as it looked, to first glance, as if it was genuine, and was printed on the genuine paper, and had a matching signature.
Police case opened, but of course nothing ever came of it, and the company got the money back as well, with giving the bank the police case number. Now of course there are no banks in South Africa that will issue cheques, and no banks that will process them either, simply because cheque fraud got to the point that one in three cheques were fraudulent, and the volume had been dropping for many years, as people went to EFT, and other direct payment methods.
Pretty much the entire planet no longer uses cheques, though the USA is the hold out, still accepting them, and also still, 2 decades plus after chip and PIN was introduced, still using magstripe data, and manual impression, as a way to accept credit and debit card transactions, despite this method being so easy to intercept, and misuse, for fraud for card present transactions, and card not present transaction fraud. Too big to fail I guess means they just pass the cost to he customers, and hope they do not switch banks to one that actually cares. Of course here in SA that means you will rarely find a merchant that accepts American Express or Diners club, simply because they are both so small in the market, and also are the most expensive merchant fee wise, with the only places that take them being 4 and 5 star hotels, where they can bury that charge in the mark up, plus also charge a nice big fee for drawing cash from these cards as well, so people can actually go outside the hotel. Every other bank charges 1% to 3%, AE and Diners only 5% or more. Good luck unless your bank is affiliated to Visa or Mastercard, which are the de facto standard for cards here, accepted everywhere, even by street hawkers as well, as there are a good number of mobile card solutions.

@LMacNeill Almost guaranteed to have a spark if the indicators were on in a turn, or the brakes were on because you were in an automatic vehicle, and were slowing down or stopped, or at night. All 3 conditions where you can get rear ended, and not helped by the electrical wiring being routed over the tank, so as to save on wire length to the fuel sender, and to keep the loom shorter to the rear lights. guaranteed a spark or three when the loom got damaged in an accident by the frame buckling, and the loom was lose to that easily torn off fuel filler pipe. fuses in a car take a while to blow, normally a second or so, they protect the wiring, so have a blowing time such that the fuse fails before the wire insulation melts, but a damaged wire can still spark for a second or so before then.

@hmw-ms3tx Had to get some machinery moved a few years ago, and the hardest part was the first 50m, because it needed to be somewhat dismantled, and then moved down 2 floors to the truck. Luckily it fitted the lift with an inch to spare.
The tank before it went out, after it had a 20 minute session with a massive plasma cutter, turning it into plates, as the original method it used to get there had involved removing windows, and a mobile crane. Took longer to connect and disconnect the plasma cutter to power and air than it took to do the job, turning the tank into pieces that would fit through the doors, and also be easy to carry.
Scrap value of the stainless steel tank was a lot less than the cost of just removing the window, and also the access for the crane was going to be a lot harder, as the interim period had seen building work occur there, so you would need a much bigger, long reach crane. Borrowed the plasma cutter and FIL to operate it from his work, he took a lunch that day, and actually left the shop.

That aluminised fabric is also used to make bags, which hold stuff sensitive to thermal damage, and they work well to keep the contents at a reasonably stable temperature. I use the old bags, which are very big, as camping blankets, as they are easily big enough to cover you, and after 5 minutes you are very warm inside from the reflected body heat. Normally a ground sheet, one on top of that, a blanket or thin foam mattress, then you, a blanket, and another on top is a perfect way to stay warm even on the coldest night. They take up little space when folded up as well.

I would guess the major reason for lack of proper guidance is because the computers and controls are in the second stage, and the first stage is mostly just sensors and actuators, to save mass in not having 2 guidance blocks.
Simplest solution would be to put only a small low mass battery and controller there, to just turn the booster around and fire the main motors till empty, or at least be able to receive a deorbit burn instruction the next pass, and then scrub enough energy to land in the Pacific in 2 orbits. Would need to have the extra fuel and oxygen, plus also the ability to relight the core engine at least twice, first time to drop down a lot, and the second to finish, after drag has been calculated from the timed burn, then probably 2 orbits later get an updated firing time and duration on the remaining fuel.
But this needs extra fuel to be carried, and the motors might not be able to restart. Otherwise just a big drag parachute to make it come down very fast and calculate the drag to make probability such that it will land in the ocean. They are just hoping that 70% water is good enough, and the 1% that it lands in China itself is fine for them, as the chance of hitting the launch area is very small.

If you are on a short runway, at altitude, with a load very close to maximum take off load, and it is a hot day, you want every last bit of power the engines can deliver, so that extra 5% per engine that you lose to the air bleed, which does imbalance flow in the compressor and combustion chamber slightly, reducing thrust by a noticeable amount. In normal conditions, where you have a lot of runway, and reach V2 part of the way down, needing an extra 500m of runway is not a worry, though your decision might also be influenced by the rejected takeoff distance you need to have as margin.
Been there, in a plane where we needed all that 8km of runway to take off, and a good bit of ground effect as well to gain velocity before climbing up. Know of one where they flew in ground effect pretty much the whole flight, due to a miscalculation in load. No way they were doing a go around in an active war zone either, they just came back with the odd bits of tree and a new collection of holes.

@Jirodyne Military does not close off airfields to land, they rely on ATC for that, and uncontrolled airfields normally are posted that this is an airfield. Snowmobile guy admitted that he knew this was an airfield, having seen the signs, yet still drove like it was a highway at noon speed. His claim that he had never seen a plane land there is bogus, it is entirely possible to drive to an airfield ( one 10km from me) at any time, and not see anything take off or landing, because it is a small low frequency airfield, and you are there infrequently. Up in a mountain an airfield will get mostly casevac traffic, and only then if some idiot plants himself while drunk on a snowmobile. Plus he likely did not take the path that circumnavigates the landing area, because that involves slowing down and making 4 turns, which in his drunk state would be hard, but instead went straight across, and hit the big highly visible helicopter there. Even if it had lights on, engines running, and strobe lights on, it is still likely he would have hit it, because of the impaired responses and poor vision.

More down to they simjply go and cut wires with the engine running that lead to the ignition switch. When it stops running that is the wire they use, and grab power and ground off the OBD port, as that at least they can figure out the 2 correct wires. Then tape up the connections sort of, and put the covers back, and done in 10 minutes. Remember the person installing is no auto electrician, just has possibly a sheet of paper that comes with the device, with a picture of the OBD port connections for power and ground, and then 2 wires used to operate the disabling. Then takes the sheet to the office, with the vehicle VIN and the serial number of the kill unit on it, and this is entered into the loan sheet. Plenty of opportunities for a mistyped number there, or the papers to be mixed, between the half dozen vehicles being done that hour.
If you buy from one of those places it is well worth being able to figure out how that works, and to simply disconnect it from being able to disable, and fix the wiring back to correct again, as those devices also have a rather high failure rate, as they are sold based on cost. Power still needs to be applied, as they often also act as tracking on the vehicle, so need power to operate.
Supposed to be removed when the loan is finished, but often are not, and you might land up with somebody having an old one getting the wrong serial entered into a lender that activates it.

Moving 12ft is easy, likely all he has to do is extend the foundation out on one side, and then the house movers, jack up the house off the foundation, disconnect service points for water, power, gas and sewage, and then they simply slide it over the 12 feet, and reconnect the services. then after the move demolish the foundation now exposed, and it is done. You do not even have to empty the house out, except those spots where you need to remove floor boards to get to the joists., and then replace the boards after it is complete.
Likely this house is built on the one parcel, and the adjacent parcel setback allows use up to the edge, especially as the 2 plots have the same owner. After he is done he can actually subdivide the old plot, keeping a buffer zone, and sell the remainder, getting some of the cost back, though now he could also apply for a rezone, to drop it back to being agricultural land, and simply mow every year and sell the grass as silage, which will allow him to forever keep the low agricultural rates, and still barely make enough money to cover the rates, or sell the land use right to a local farmer for the annual rates amount.

Still have a pack or three of Phillips 22W tornado CFL lamps, which do actually last around 8 years in use, on all night. bought them around 2000, a whole case, and they will probably last me a long time still, as they are the last lamps they used good capacitors in, and also used full size TO220 transistors in on the board, so do not cook themselves to death like the new ones. Still have black PCB material at EOL, but at least the transistors do not run that hot that they unsolder themselves, like the modern ones do.
The main capacitor also sits in the socket, so runs cooler, though of course it still get well toasted. Pretty much every one goes EOL with the filaments wearing out, not from electronics failing. Which seems to be the main issue with LED, in that you either have the driver die, or the dies themselves get the black spot of death on them. Ah well, if I run out of tornados I still have a number of magnetic ballast conversion units, which plug into a standard B22 socket, and take a PL lamp in the top, those pretty much will run till the plastic falls apart. PL7, PL9, PL10, PL11 and PL13 all work there, the magic of constant current, and glow starter construction in the lamp.

For commercial aircraft the biggest problem is not just jamming, but also incidental radiation from other devices, like the emissions of all your cheap unshielded IOT things in the house and area, that have no shielding, and no certification at all, that have random harmonics on the GPS frequencies. This gives you random dropouts, which means your GPS will have degraded accuracy at times, and also makes it harder to acquire new satellites, as the poor signal, despite appearing strong, is not going to decode well. Very common, and you can see it with a GPS that does plain GPS, like a stand alone one, not a phone, which uses assisted GPS, and which gets most of the location info by using local wireless signals, and local cellular tower locations. Turn on from cold, and you will see areas where getting that initial lock is hard, and your initial location is very poor, varying over a huge volume.
I see it by me in some commercial parks, where the initial location can have me up to 50m below sea level, which is king of hard to do without being a submarine, as I live at the coast, and this area is actually only 5m above high tide mark, as the river that flows there has some rather salt tolerant fish, and the odd crocodile as well.

Reason for the colour split is probably that the ADC is using the blanking interval as a way to reference black level and peak white level during the conversion, so that the input signal can be offset and gain trimmed to make full use of the limited number of bits of the ADC, probably only an 8 bit flash converter ( which still needs a resistor ladder and 256 comparators on the flash converter chip to drive the logic, that provides a binary value equal to the peak value of the ADC input) that is fed a sampled voltage of the black level as bottom reference, and then fed a buffered voltage equal to peak white for that frame. 8 bit flash as the design probably was late 1990's, and faster flash converters with higher resolutions were very expensive, but CMOS flash converters with 8 bits ( CA3308 for example) were almost same price wise, and could sample at 15MHz with 8 bit resolution, just needed a fair bit of work to make maximum use of the limited input voltage range.
Likely 3 ADC's all fed after the colour matrixing decodes the signals into luminance and the 2 chroma difference signals, and then the digital values are used to generate the 3 bitmaps of the frame, for sequential read out and conversion back to analogue video for the CRT. If you select RGB input they use the 3 converters direct per colour, so no distortion, but analogue video would need the matrix to get the signals apart, and red is typically the one that suffers the most, as it is always the poor cousin to the dominant green signal. Having only 253 values available you wanted to use the range fully, so had to use the blanking interval sampling, as in a VCR, to set the gains, thus the Macrovision interference, and the same for head switching tearing, as that also corrupts the reference levels in the blanking interval.
The red would probably be due to the maths required having underflows or overflows, and ignoring the carry or borrow in the output to the DAC driving the CRT after the frame buffer. As the data is only there for a frame no real worry, but a really interesting technique used there, which I think was pioneered by Tektronix in a series of digital oscilloscopes, that had a colour screen, using a very similar system.

Yes people go for the manufacturer interval, which is designed to get the engine out of warranty before something fails, and thus you either buy a new engine, overhaul it, put in a used one, or trade in the scrap for a new one. All 4 result in profit for the manufacturer, and the long oil change intervals also are profitable, because you go to the dealership, and they can sell you new pads and rotors, because the long interval means you were through the pad and damaged the rotors, or the suspension is shot and needs bushes. But the manufacturer only has to pay for 6 oil changes in warranty as part of a plan, but gets to upsell 6 times, and no 7, with the big sticker shock, is not covered, and you have to fix it, as you still owe money on the loan, and it needs to run for another 2 years before you have paid it off. So loan more money from the dealer, now you are there for another 3 years as customer.

Still got the Gedore socket set I bought when I was 18, and it still has all the sockets and drivers, though I did add in both a wobble extension, and a regular swivel as well. Got a toolbox with the rest of the sockets i got over the years. Most used though is a cheap Chinese special, on sale because it did not come with a 13mm socket, so my father bought it, and simply added a 13mm Gedore socket in he picked up on a flea market. Tough set, been abused a lot, and aside from scratches nothing else damage wise, just keep the ratchets lubricated, and clean then every so often.

Note LOX is the same, with the added benefit of it also catching things on fire as well. Done the freeze stuff, though the snake I did was dropped, fumble fingers in the gloves, and it shattered when it hit the ground.
Also remember the liquid nitrogen will slowly condense oxygen out of the air with time, so the end of the dewar time, if it has not been opened, will contain a very high contaminant of liquid oxygen, so be careful in using it, as it will actually enhance combustion, and will catch things on fire with only a spark. The laboratory method to get liquid oxygen, as it normally is not provided because of the hazard, is to take a cylinder of medical grade (or welding grade if nothing else is to hand) high pressure oxygen, and slowly bleed it, through a regulator, to a length of small diameter, 6mm to 10mm copper, stainless steel or mild steel pipe, and place a coil of the pipe in the liquid nitrogen, so that at the open end of the pipe you get liquid oxygen that condensed from the gas appearing. The 2C difference in boiling point at standard pressure means you lose some of the oxygen still, but the majority will condense out as liquid for your experiment.
Oh and high pressure oxygen or LOX makes many things burn, like shoe polish, graphite seal packings, any oil residue, most plastics, and clothing. Reason the LOX tanks were all in a separate blockhouse, each one with it's own heavy steel blast door, and with nothing else at all stored in there other than the LOX tank, the filling station and the hoses for this. On a 40C day though this was the coolest place to be, always under 10C, and your breath would come out as mist, and especially when the tanks were full and venting, and the floor had a thick mist all over from the vented liquid.

@garywheeley5108 They likely carried at least 3 spare tubes for each position, and the same for light bulbs. However the bulbs and covers are almost always mounted with sturdy anti vibration mounts, so they do not really shatter as seen in the movies, they survive quite well, seeing as normally they have very sturdy heavy duty filaments, with a lot of supports.
Submarine designers know there will be always water and vibration, so they make sure that things like lamps and the radios, along with all sensitive equipment and panels, are mounted on anti vibration mounts, which also serve a dual purpose to keep them from buckling as the hull is compressed at depth. Even the walkways and decks have the same anti vibration mounts, both to keep from transmitting noise to the hull, and to keep them from buckling.
Damage from depth charges that breaks a bulb normally was pretty much followed by the hull breaching. Also the light fixtures all had at least 2 lamps in there, some having 4, 2 being filtered with a red glass, used in the conning tower so the captain could have night adapted eyes to use the periscope, or to run at night on the surface to charge batteries and change air. Submarines in that time were not well lit, which is why they had a lot of battery powered torches, to see to do maintenance and repairs. Those batteries were very carefully husbanded, though I would say a few enterprising submariners also managed to "acquire" lead acid mining lamps to use, as those are easy to charge off the ship batteries.

Half the time the police stop and park by the no parking, yet tow cars from there, so long as they are not police vehicles. Me I used to park in the loading zone, no way they could stop me, commercial vehicle, and I was normally there for a delivery. Normally cash to pay for other vehicle parking tickets, though I would also check just in case they had one for my vehicle, or my friends as well. People take the tickets off the windscreen, even though the city, as in a story on Reddit, where they say putting on a windscreen is a valid way to serve, so he told them the cheque was placed on the windscreen of a city garbage truck, as that was a valid way to pay them as well.

Canister normally gets dirty because it sits on the ground. Split sort of self cleans because it is above the ground, and thus does not get so much dirt on it. Think this self clean cycle is a manufacturer quirk, most mini splits do not, as they only have a single fan speed, and thus can only run the fan at a single speed, or modulate it to drop speed down, you would need to have an outdoor unit inverter board, and thus a digital comms between the two, to get them to do fan speed control and direction.
Only reason I can see for it is in freezing conditions, where the coil is swapped to cooling, and then the fan runs to pull the defrosting ice off it, and they left this as a default behaviour. Do not see it in temperate climate units, they do not have to act as heat pumps much below 0C, so can get away with simply turning the fan off outside, and running as cooling, with indoor fan off as well, till the outdoor temperature sensor starts to rise above 0C, indicating defrost is complete.

Umpires have a big problem, in that every spectator thinks they are all better umpires, and that the umpire on field is either blind, deaf, or being paid off by the other team. Might be true in some cases, but generally not. At least this is baseball, if you are a football referee, in a lot of countries you will have a police escort to and from the airport, and a set of them who escort you on and off the field, and to your hotel, and stand outside the door. Some people take the game all too seriously, and there is a lot of big money riding in bets on the outcomes as well.

@jeffostroff But for the day it was perfectly acceptable steel, only after WWI did they start to appreciate the role that adding manganese does to improve steel, and how sulphur makes it cold brittle. That steel passed the tests which were in place when it was made. The issue showed up in the first Liberty ships being made, where they were made fast, cheap and light, so used thinner steel, and showed up as cold cracking in places with sharp corners, which is why you get rounded corners now on all hulls, so as to not have stress risers.
The cracking also showed up in the coldest weather, which probably was the reason some of the ships sank so fast when attacked by U boats, in that the brittle steel simply tore from the stress, instead of yielding and deforming like it would do if it was only 10C warmer.
Only after the war when the victors looked at the processing Krupp did to their steel, which did not suffer from this (war secret) did the standards change.

@lawrencedoliveiro9104 To run a run of them, using existing masks, the quote came to $10 per transistor, with a lead time of 18 months, and a minimum order quantity of 100k units. I needed 2, so went through the pain of putting in the paperwork, to have a common part substituted for this obsolete superceded transistor.
The 100k 18 month lead time though is pretty much industry standard, unless it is for something like a sea of gates ASIC, where you only pay for the final metal mask, and run off a existing batch of nearly fully made wafers, where you will get 10k units, 100 wafers, one carrier full, run with your mask, processed and packaged for you. Make sure you got it right, because they only will do a basic wafer test to see if it responds to signals, and is not shorted too badly. Then it can be as low as 6 weeks, though you will pay.

@darksu6947 Yes they do, but in most cases it is limited in resolution to around 2-5m, though the one office I worked in had it at 1cm resolution, for some reason. However for a municipality to use those images, in any way related to city or town functions, they are required to buy a licence to do so, which gives them very limited rights. Now, if the defence went to Google, and asked if anybody in the city management, either at home or at work (so all map lookups with geolocation in the IP allocation of the town, or any Google account that does get used in the district even if via a VPN), had looked at the area in question within a certain distance of the house, at any resolution, in the weeks prior to this, then they could allow Google to join in to a copyright violation against them, and they would have the entire Alphabet legal team assisting in the case, and the ensuing massive copyright claim against the town.
The google maps are limited in resolution, unless the city or township has paid to use them, then they get the latest maps, and previous ones, at full resolution when acquired. Same for street view, you can get rights to use it for commercial use, which is defined as either being used to generate money, or work that is going to result in the payment of any consideration.

@jerrykinnin7941 Problem with dumpsite methane is the contaminants. Major one is silane, SiH4, analogous to methane chemically, and a by product of all the silicone that got dumped there as either furniture polish, silicone sealer, silicone parts like seals, and other such things. This when burnt in an engine does not, like methane, produce carbon dioxide and water, but instead results in the formation of silicon dioxide and water, or with methane silicon carbide. Both are deposited as thin films on the cooler metal parts of the engine, and both are commercially used as very effective abrasives.
Thus your engines running on dump site gas tend to have both a much shorter oil life, because of the silane and other contaminants like carbon monoxide and other things like CFC and HFC slowly leaching out from PTFE parts, and also suffer enhanced wear from the abrasive dust that gets deposited into the oil and on all the metal sliding parts. They cannot easily be filtered out by the oil filter, and clog up the filters, and wear the engines out prematurely. Where a natural gas engine might do 20k hours between overhauls, the dump gas one might be lucky to reach 5k hours before blow by is so severe it burns more oil than fuel.

Postal locks are bought on the spec of being cheap, and thus are sloppy and simple to pick as well. So easy for somebody to go to the post office late at night, stand there, appear to post a letter, and then pick the lock, or even just have a key, as those locks are all keyed alike, so one key fits almost all, and you can just buy them as well online. Then empty out the letters and bag them, and do the fraud for the next week, then repeat.
As well the post office actually does not have a literacy requirement to be a postie, not part of the hiring, so plenty are well past the point of functional illiteracy, and well into "match most shapes" literacy, and those they cannot they simply dump. Protected from being fired by the union as well, so they get a job where all they do in move bags in the office.
Another is internal theft, which is why my local post service has the motto of "We Deliver, Whatever we do not take", because it takes them 6 weeks to deliver a letter in the same postal code, even a letter sent via bulk mail, delivered to the sort centre, and going to a PO Box in the same sort centre, literally a floor above. Plus harder and harder to find post boxes, they are going fast, and as well so are the post offices, the one office now serves the area that used to be covered by 8, all closed down, and all in one single building now. The staff complain about being paid late, the deductions going off, but not being paid over, so some are losing medical and pension, and even tax not being paid over, so they get dinged tax time as well.

They are the outliers, made on a production line which was at optimum, and with the line newly set up and aligned, so the batteries were at the best point the plant could make. Then the plant machinery wore, the seals got less good, and the continuing cost cutting meant the plant went for lower quality seals, lower quality fill and other components, to get that all important price point down another cent per thousand cells made.
Brand name is actually not important any more, as your battery could wear one of a hundred names, just the outer sleeve applied, and the blister, is different between them, but the actual cell is identically poorly made. All manufactured at the lowest cost, by the cheapest quote that thinks they can make the volume, and still make a little profit per cell overall. The major price increase comes from the middleman who distributes them in the USA and the company who sells them, the manufacturer of the cells gets only a fraction of the retail price.
Have you not noticed no manufacturer any more gives a warranty to repair or replace equipment damaged by leaking batteries, only a warranty that is limited, to a set of similar batteries, when the old ones leak before expiry date.

Zinc is used because it is easy to deposit onto surface of steel and steel alloys, and it is a reactive metal that forms an oxide coating as well. You do get aluminium coated steel, but it is a much more expensive coating, as you have to apply it in an inert atmosphere. Zinc you can apply to clean bare steel in an open bath, either by immersing the cleaned and acid etched steel into a bath of molten zinc, or by using electrochemistry to apply it in an electrochemical cell from a zinc anode, using a zinc chloride in water solution.
Aluminium you can do neither, the melting point is too high to have it out in the atmosphere, as it will catch fire, and in water it is too reactive. Thus you have to apply as a coating via sputtering in a relatively high vacuum, running a cleaned steel sheet from a roll to another in the vacuum.
Chrome and it's alloys with steel work, but rely on the formation of a chromium oxide layer to passivate the surface. Thus stainless steels, but they are all slowly going to corrode as the thin surface layer wears, and are not really suited for salt water use, or near the ocean, as the saltchemically reacts with the coating to dissolve it with time. Any chloride will do it, so even road salt will slowly erode it away.

@wgowshipping Yes and most new ICE cars are shipped with a part tank of fuel, simply to cover the driving needed to get from the plant to the ship, and off the ship afterwards, into the receiving warehouse at the ports. So each will have roughly a half tank of fuel in them. EV's will, if new, only have a part charge as well, basically the initial test charge at the plant, then the discharge where the battery pack was tested for initial QC and to allow the BMS to get a capacity map for each cell block. Then whatever was used to drive on the ship, and the losses from self discharge or the battery needing to maintain temperature.
Yes likely they are going to require disconnecting the 12V battery pack once parked, so will make shipping take 15 minutes more per vehicle both ends, as they will have the additional step after loading and tie down, and the same before undoing the straps. But will also result in some strange faults as most modern vehicles really do not like the battery disconnected, and many luxury vehicles, especially those with electric handbrake, have a second auxiliary battery as well that you need to disconnect, which often needs dismantling parts of the interior to reach it.

Alfa had that, though they also did a bigger difference and had inboard calipers, so that a vehicle with standard 15in rims off the factory could have 19in disk rotors, and thus much better stopping power. Handbrake worked the same front pads as well, so the handbrake mechanism provided a lot of holding force, if adjusted properly. the big rotors really helped in driving sporty, you could scrub off speed faster than you could put it on, and those massive rotors did not fade much at all, unless you really were abusing them.
Unfortunately they could not make an automatic adjuster there, so you would need the 2 special Alfa tools to adjust the handbrake to work, or you would find that it barely held after a while. My father did not want to pay for those tools, so instead got some steel rod, and an old 10mm socket, and a 5mm hex bit, and spent a few minutes with a gas torch brazing the hex bit on the one rod, and the socket outside to the other one. That then allowed him to spend 5 minutes a week, when checking the fluids and general condition, to undo the lock nut, and wind up the slack in the cables for the hand brake, to keep it consistent. He wanted it to grip by 3, and fully on at 5. Leave for a month and you might be almost vertical and still have the car able to roll. He really loved that car, despite it seeming being built entirely from compressed rust.

Simplest method to stop this is to only use virtual cards for the transactions, which pretty much every bank offers today. Every online transaction I use a virtual card for that merchant, and only transfer the amount they are taking into it. Only ones that do not have that are those I have long term relations with, where they have proven they do not do this.
Note this does not include Metro payments, those are not automatic, but only on invoice, as they mess up that online direct debit all too often.
Never give real bank details, only a virtual card, which has all the attributes of a regular debit or credit card, except you can set a hard limit on it, stop it immediately it is used, and change the verification codes right from the banking app if need be.

@gregkramer5588 Well, a lot of the EU petrol comes from refineries in Portugal, and also there are large sugar beet plantings used to make ethanol, plus sugar imports used to do the same. I doubt Ireland actually has a oil refinery of it's own, like many smaller countries also lack, so would import a lot of fuel from the closest one, which is Portugal. Incidentally that refinery also ships a lot to the world, as VLCC tankers are very cheap to rent when travelling down Africa back to the oil supply countries, so you get low price shipping if you are bringing in, what to them, is just ballast in a tank.

Those horrorlytics in there do dry out with age, as they are often cheap no name brand units of questionable quality. However film capacitors of the same capacitance and similar voltage rating can often be put in the same place with no issue. Cables are just snake oil, at under 10m I just use regular 1.5mm mains cable, and you cannot tell the difference between that and the $5k cables ( I got some, after the test I recycled them into test leads, because they have PTFE sleeving so are somewhat smoke proof) in most cases. With the sound source being a PC audio chain, and the speakers and amp being low cost used, they are absolutely not needed.
Did have a house where the expensive cables were used, till they vanished into the floor, and were cut in the hidden side and joined with wire nuts to 2.5mm house wire to the other end. Twisted to get them to lay together, then joined back to the other end the same way under the floor. HIFI " Guru" could not tell the difference between them.

@Gnomezonbacon Well, insurance company would delay the payout till after the police investigation, so at least 6 months of waiting for any payout, and her needing to either pay to get the vehicle repainted immediately, or store at her cost for that time. Then when it comes back they will both limit her insurance, and up the premiums, especially because the agents there will hate her as well for her bad attitude, so will handle her claim exactly to the book, and stretching out all timelines to the last minute as well, plus demanding every piece of paperwork be exactly correct, and with absolutely no errors, or it will be refused.
Then a call for her tags being expired, and the vehicle towed off as well.

Making an engine that uses elemental fluorine is going to be hard, seeing as you will have to make a pump that can handle the volume, and last long enough, as you will be having a race between running out of fuel, versus running out of engine. These will be rockets with engine rich exhaust even running perfectly, let alone when they get upset. Plus remember bulk fluorine liquid will burn things you think are non flammable, sand, asbestos, water, steel, aluminium, unfortunate people downwind......
now think of the thermal shock in the first combustion chamber, and that whatever you use for injection of the lithium will be dissolving in the hot liquid, and whatever you are using to bring in the fluorine will be doing the same. You probably will also not want to use pure lithium, rather a lithium sodium alloy, as those do have a lower melting point at least, and with Gallium you can get it low enough to use ordinary steel alloys as the tank.

I started with RH 4, on a machine that, while capable of just about running Win98, absolutely was perfect with RH4, and worked well, even able to play video in full screen,only 640 x 480 VGA though, because that was the best the screen and display card could handle in 16m colour mode. Had that for a while, even upgraded it to RH5 as well, after ordering the collection of disks online, as dial up was not exactly able to do the download reliably. Stopped some time after that and moved to Debian, then ubuntu and now with mint, and like having most old hardware just work, and as stuff that no longer works with Win10 is still common and often free, you get a lot of it.

@@DKShoneys-dc2dp South Africa, and these have been common at all fuel stations since the 1990's, even if they were attached to a cable that provided them with a dial up connection. Right at the pump, and also in the kiosk, as pretty much every fuel stop by me has an associated convenience store, where you can buy stuff while your vehicle is getting fuel put in, the windscreen washed and tyres checked, along with checking the oil and topping up washer water as well. Before that you had a fuel card, and then would have to get out, and go to the kiosk, where they would run your credit card, debit card or fuel card, using a impressioning machine and carbon chits, so you got one, and the garage got 2. Sign, and after a week your card would be debited, or you could write out a cheque. Had an account at the local garage, and there they also had fleet vehicles coming in, using a tag that you had on you, that had the account details electronically in it, and you signed the slip.

Yes common faults there. Oil cooler you can do without removing that manifold, but easier if it is off, but doable, and there is an entire kit to do it which is cheap. Likely will need a new valve cover gasket as well, use the blue one there, it will last longer. 2013 at least it is not the later generation known for cracking pistons. Not a bad car, yes it is a Daewoo Matiz, rebranded as Chevy Spark. Quite reliable vehicles in general, you just have to maintain them properly. Will bet when you pull the coil pack (pre 2012 had a coil pack outside there, and 4 wires, so the coils do not run as hot) the plugs will be swimming in oil, and the old valve cover gasket will be as hard as rock.

Not really, aside from a redesigned gasket with some sealer between the surfaces, but they will all do this with time. Essex engines are pretty reliable though, not going to give issues other than those head gaskets, simply from the conservative design. The only way to fix them would be a cast steel head, which ISTR was an aftermarket thing, that made them really bullet proof. They did a good bit of work on them over the decades, as this started out with a single barrel carb, and had fuel injection added later. Just they did find a lot of use as power plants for other applications, little more pep that a 4 banger, but not too much change in length, so lots were used in agricultural and specialist equipment. Not a bad V6 engine though, friend had one in his Ford, and the engine was not an issue, but the diff, sure was, little underspec for the 3.0l power plant. Sure was heavy on fuel though if you were ever hard with the right foot, but enough torque you could drive all day in 4th gear in town, and never change gear.

Exactly, I started down this with a machine that had been obsoleted because it was not capable of running Win98SE properly, so it was replaced with a new one. I took the old machine, and ordered (yes you could order Linux on a disk for free, just paying for the actual disks and postage) Red Hat 4.0, and installed it on the machine. Booted, ran nice and fast, and was able to do more than I needed, even including having working VGA colour and sound, along with networking, right out of the box, which the original machine had struggled with working before. A good recycling of a Slot 1 150MHz Pentuim, with a whole 16M of memory eventually as the older machines were upgraded and the RAM was robbed from them.

So long as the algorithm seed is secure, so that your method can be known, but the initial input is not, like SHA256 does, and you keep it safe, that works well. No way to tell provided the site is used as part of the input, and then a secret seed as well, then it makes unique and random keys, that will always be the same per site, just near impossible to decode, even knowing that part of the input was the site URL, salted hashes are very secure, so long as the salt is secret.

Will say that any driveability issues, you get the vehicle with a cup of fuel in the tank, but a fuel pump almost always will show up with a near full tank, so you have to drain it out somehow. Yes that fuel rail was bad, and your fix was a great job.
A tip if you need to bend that hose, but have no mandrel spring that will fit inside, is to simply take lots of copper wire, and feed it into the pipe, to past the bend area, and heat it up with the hot air, then use a tube bender to quickly make the bend. Leave to cool, and pull the copper wires out one by one, till they are loose. The wires keep the pipe from kinking, and then it will hold the shape. Otherwise do like the AC manufacturers do, and wind a steel wire tightly around the outside, making a wire diameter gap between turns, and use that to keep the pipe from kinking. Again remove when shaped and cool.
Another cause for crank no start, but will start eventually, can be the fuel pump relay, very common to have it go faulty and intermittent, as it has both power and a keep alive signal fed to it from the ECU on older vehicles.

Oxygen fire was a part of training, in that many things you think do not burn, will burn in pure oxygen, including PTFE, Halon, and aluminium parts, along with steel and stainless steel parts. Your oxygen system itself is cleaned to make sure easily combustible things like oil, skin residue and such are all removed during service, and all parts are washed in pure alcohol to clean them as final step during install, and are sealed away as well as much as possible.
With the mask unit being replaced just 10 flights before, it is possible there was either a bit of debris in a pipe, or a plug was not correctly installed (hard to get to the connectors under the unit, without stripping large sections of panelling off to get a visual check, so easy for tramp material to be in the connector, and causing an intermittent contact) and thus the valve likelyr was stuck partly open by some tape residue from a cover, or had a tiny bit of grit in it from exposure from the service store to the aircraft on the hard stand, with uncovered ports. Flow through the sticky valve, and the intermittent contact allowing flow, so that eventually the concentration in the box was enough, and the tiny bit of tramp metal caused a spark, and in an enriched atmosphere that was sustained, causing the plug to burn, and in turn burning through the rubber hoses that were keeping the oxygen inside the pipe. Then hot oxygen rich gas was flooded into the side cavity, where it soon found likely accumulated oils and such from hydraulic systems, along with all sorts of easily burnt paper and fabric parts, and this then spread to the wiring loom and started all those cascade failures as systems, depending on the locations of the power and control wiring on the surfaces of looms, melted and shorted out, tripping breakers and leading to the ACARS messages, before the ACARS system itself was cut off.
CVR and FDR likely survived so long because, as long wires in the loom, they were laid first in the looms on the assembly board, and then the long excess sections out of the loom got coiled up on the panel pin board, till the loom was complete, checked and laced, only then being laid out on another panel, to be carried on to a bulkhead connector leading to the cabin cabling loom.

Yes, but most of them have probably had at least 2 engine rebuilds by now, simply because the original parts wore out. Taxi use is hard on a vehicle, so the companies that do it will spend a bit of money on maintenance, plus also regular checking of the vehicle itself. Not just drive it till it says service, and then think about going in "soon", but daily checks of oil, fluids and tyres, because that is what keeps you earning money. You would notice quickly the glitter oil, and immediately do action on it, not just drive till it stops.

GM is going to go the way of the dodo soon. not because of EV's, but because they just make junk, and those competitors, who they use for manufacturing under the GM brand, are going to decide that they do not want to get all the work and worries, and none of the profit, and start doing direct sales. Then they will also stop supplying GM, and they will vanish as a footnote.
Same with Ford, they are deciding to go with compensation size trucks, and that market will be eaten soon, and with the next round of fuel increases, simply evaporate. There will be huge lots filled with brand new Ford trucks parked next ro the rusting brand new Hummers, and GM cars, waiting to go to the crusher to come back as a Chinese made vehicle.

Problem is it was shipped out a century before, and the cranes at the time were mostly steam powered. Now most are for intermodal, so can only lift the theoretical 60 tons of a full container, though there are plenty of times that they found heavier ones, up to 132 tons inside. The problem is getting the old iron apart easily, as likely after a century most of the fasteners are now rusted together, and in any case much of the final assembly was done with hot rivets joining big sections together.
Thus they had to move it as a unit, using the existing rail network, as otherwise it would have been parted out, and then likely 5 abnormal loads travelling in convoy, then onto a ship, probably a RORO that can take the trucks. Expensive, because you now have to pay for both ways for the trucks and drivers. As a single unit it is able to be taken as breakbulk cargo, which pretty much any ship is capable of, even a container carrier like they used, running only part loaded. Biggest problem was cranes, the Durban docks will have no problem with 300 ton loads, but those berths likely were all booked, so they needed to rent the floating crane. Same for the other side, you have pretty much any big harbour having a heavy crane available, especially if they also handle large loads, which is Durban, though a lot of the loads are limited by the city infrastructure rather than the harbour, you have width and height restrictions, but not mass ones, bringing stuff in there.

Actually he can also be charged with tax evasion as well, as the cars the state uses do not pay any road taxes, or toll fees, or any fuel levies, so his use of the vehicle after hours means that he in effect was not paying those levies, so he was not paying the tax as well. Plus the theft of government fuel as well, which is also a rampant thing.
One vehicle by me filled up the fuel tank 15 times in one afternoon, yet the odometer reading showed that the vehicle only drove 5km in that afternoon, and it was supposedly still in the government garage, not actually booked out. But 15 100l fill ups, on a vehicle with a 40l tank. Of course that went nowhere, corruption of such a small amount, while nothing is done to those who steal billions.

@gags730 My father was doing that post war, importing 46 jeeps bought as war surplus to Central Africa, and assembling the crate units there in his garage. Due to the QC being less than stellar, he had a big order of spare parts as he started, sent at the half way mark, to repair those that were faulty. So at the end he had the 46 he ordered and paid tax on, and the spares that were left over from the faulty units ( engine not working, order complete engine as spare, and fix that one later on, same for transmission and other parts) enabled him to make no 47 for use around the shop, as it could not be registered and sold.

@WrenchingWithKenny Yes exactly the same, finding power on return wire in a single phase system means either high resistance joint, or a broken wire. But in the USA with split phase high power circuits will have 2 hot wires, because to run high power loads you need 220VAC power to supply the needed energy, and not 110VAC, though many of these appliances, like driers, need the common as well because they have 110VAC controls as well as the 220VAC active elements. So a 4 wire cable with hot, hot, neutral/common and a protective ground wire. 3 phase power is not common in the USA residential side, but there again you get some really odd configurations, because the suppliers have to give the 110VAC supply as well, and want to use the same transformer to give it.

@jimAndCheryl No but lane splitting is legal here, and the most common bikers are delivery bikes. Standing joke the biggst biker gang is the Checkers 60 sixty bikers, because they are all over, and drive like they own the road. Did see one recently being beaten up with his own helmet, because he rear ended a BMW, and the driver was a tad upset. Just drove around them on the pavement, like the other cars did, while the woman up the road waiting for her delivery was looking on. just another friday afternoon in South Africa, did tell the neighbourhood watch car a little further on he might want to go watch the fun, but not worth making the call to Metro police, who would already know the biker has no insurance, and probably no license either, and also illegal immigrant as well, because you need zero paperwork to become a driver for these delivery services.

Worked with a guy whose entire job was to put tyres onto aircraft wheels. Nitrogen used because it is water free, so there is no water vapour to condense and freeze up in flight, unbalancing the wheel. Easiest to use bottled nitrogen instead, which we filled on site from a cryogenic tank and filling plant. The biggest worry he had was the first time to inflate those tyres, you had a special cage to do that, in a concrete hut, so that a faulty tyre or wheel exploding would not kill you. Aircraft tyres are also much heavier in construction than your typical car or truck tyre, 16 or more plies of fabric in there, and you have limits as to how many plies you can have show before you replace them.
However a single poor landing can easily take all those brand new tyres, that you literally just put on the plane before take off, and turn all of them into scrap, as you have scrubbed more than 6 of the 16 plies off there. Commercial aircraft also tend to have more than one wheel per axle, so that even in a blow out you at least have a wheel there that will take the full load, even if the tyre needs replacement afterwards.
Most memorable was seeing ( and hearing 3 seconds later in the holding pattern) 2 pilots land their C130's in a high cross wind, and scrub all the tyres to replacement point in a few big grey puffs of smoke. They had no runway choice, it was that or fly back. Plane I was in had much better cross wind capability, we did not even feel the touch down.

First rule of DNS is not to use the ISP provided DNS in the most cases, because they generally are high latency, and running on a server that is both old, slow and massively loaded as well. Best is one like Cloudflare, who has multiple DNS servers, all probably very local to you at a data centre, and they are both very fast, and also a cluster of servers behind a load balancer, so very responsive, latency is only a few short hops from your location, to a local node, then a area node, then possibly another hop to the CDN network at a local edge data centre.

Yes, and the 2708 is, like all early EPROM chips, in need of a substrate bias of -21V, and also is programmed with 25V on the program pin. Can be left on for program and verify, but really not a good idea to have it present on power off, as you will find some random locations get written to logic 0, often only a bit or two along the line. They get really unhappy, and refuse to work, with that substrate bias missing, but generally, other than not listening to the address and control lines, do not often blow up.

I took oil to a recycler, but remember that if the oil is mixed in the drum, old oil with gear oil or water, that entire drum is going to be used as burning oil, or added to bunker oil as a reducer, or used to make roads. Old oil take to the recycler in containers, and let them keep it that way. I took 2 drums of gear oil there, and they liked it, clear, though it was 20 years old oil, but it is still recyclable, and they pay for old oil that is clear much better than for mixed oil. The dealership next door abandoned premises, and in there was a 44gallon drum of mixed oil. I called for my usual 5 gallon pick up of used oil from machines, and asked them to take the drum. The amount they paid for the 44 gallon drum full, which went drum and all, was a tenth of the price they paid for my old oil, but they wanted the drum as well, useful things for a recycler to keep around.

Only the outer 2 steam turbines could reverse, and you had to stop them, and brake the shaft, then move the steam valves to the alternate position on the main shaft cam, so that the order of operation would be changed. Then you used a small steam donkey engine to run the engine to the point it is on the inlet stroke and slowly open the steam input. Then the steam runs it in reverse, and you increase flow and pressure to the desired speed. Central steam turbine would not be used, as it did not have the ability, due to being a steam turbine, and thus having blades that only faced one direction, to be reversed, so it would be bypassed, and the steam from the side engines would go direct to the condenser, dumping massive amounts of heat into it. Running in reverse is very inefficient, you lose a lot of the steam energy that way, as both the propellers and the bearing blocks that transfer thrust to the hull are optimised for forward motion.

Also remember that not all RIFA capacitors are used for mains filtering, they are common in SMPS units as part of the actual circuit, as they will survive the spikes and surges that are part of normal operation. Often also used because they had to put in 3 for the mains, so instead of specifying a different one internally for other uses they went and simply used the same capacitor, so you might find them all over a monitor doing work in the LOPT stages, and in deflection across the yoke as a filter, and all through the board as coupling capacitor and such, because ordering one value in bulk is cheaper.
i have a box of blue ones, that are not smoke generators, despite being probably 40 years old, used with the moulded in stranded wire leads as add on to LED lights, because the modern ones do not come with ant filtering, as that costs the manufacturer $1 more in parts and a bigger case, and adding the external capacitor and MOV does help keep them alive longer.

They fixed the disclosed vunerabilities, but you can absolutely guarantee that there are also unkonwn ones that are still there, and not disclosed yet, and that the fixes they did also have introduced further bugs that can be exploited. Remember that the Space shuttle had what is the most expensive code ever written, each line cost collectively over a million dollars to develop and verify, and yet, at the end of the shuttle program, they were still finding bugs in the code that either caused an edge condition, or which were subtle ones that caused slight errors. Even modern code has had bugs found in what is supposedly known working code, stuff that is the backbone of the entire modern connected world, and often the only solution is to say to people to throw this stuff out and buy new, because it is impossible to fix all of it, or the original manufacturer of the hardware no longer wants to support it at all, or is totally unable to do it, due to no longer having the expertise.

Rebooting also fixes printing errors, as many print drivers are rather notorious for having slow memory leaks, along with the OS itself as well. Win95 also had that notorious 32 bit counter that would blue screen if your uptime rolled over. Only 2 computers have really good up time, being the twin Voyager spacecraft, where they have never been rebooted, mostly because nobody has a long enough screwdriver to reach the switch, and because the hardware has a lot of fault tolerance built in to it, Reboot the one and it will not come back, as the primary radio receiver is failed, along with the secondary, but between the 2 it can still communicate, though you just have to spread your message out over the band it likely is listening to, to get it heard by the failed receiver that still operates, but on a non compensated frequency.

@speedkar99 True, but the alternator is also generally going to deliver full output at roughly normal driving RPM, and at lower or higher RPM will limit power, high side regulator cuts power, and at low side the magnetic field cannot put enough power out. Idling will provide a certain amount of power, but with heavy loads on, like lights, heating and such, idling will actually discharge the battery down further, till the resistive loads drop in power to closer match the alternator output.
Modern cars though control alternator output via the ECU, so the regulator is merely there as power amplifier, with the ECU determining power demand, and backing off power as engine RPM rises, though idle will still cause discharge, but the ECU will also then command loads off when the voltage drops too far. Done so the manufacturer can use a smaller, lighter battery, and thus only has really enough capacity to start the engine, it will idle at higher RPM to charge the battery automatically, which them is a big fuel waste, in that you use fuel to charge a battery only, and thus are throwing 70% of the energy in the fuel away as heat.

Had one who said the textbook is expensive, and not worth it. Then also had an undergrad who also funny enough had a copy of the book, and who used the professor's code on the uni copiers to make a lot of copies of it, double sided, and placed in a bag, so you could punch it and put it in a file. Being semi used to book binding I simply took this pile, made sure they were all in order, and put 2 sheets of card front and back, then used PVA glue to bind it instead, with a linen backing to make the spine supple. Worked well, and it held up to the use it got, even if the copy was somewhat poor, seeing as those copiers had already clocked up well over the 100 million copy mark, or a Xerox would say, just run in.

@carabela125 Not the machinist, just the guy who ordered shafts, made in India, shipped to the USA , and then shipped half way back, and they came in somewhat warped. Tool maker I know looked at them, decided they were useless, so sleeved and redid the old ones instead.
that at least held up the 3 months the replacement shafts took to arrive.
He also was a guy who ordered a 100kg brass casting, and at the end it was a 5kg thin wall complex bushing, took him a week to make. Customer was very happy, as the original manufacturer was long out of business.

@Making_Karens_Cranky I did some studying next to a massive concrete cube, called the Z facility. Officially it did not exist, and was not shown on any official maps. but had a municipal bus route running through it, and the bus driver was one of a very few civilians with a top secret security classification. 2 drivers, so the one could have weekends and holidays. totally gone now, though pretty sure the entire contents got loaded in plain white containers, and trucked down to a port, where they got loaded on a "Panamanian" registered ship, where the entire crew was young,, fit, and sported crew cuts, and spoke no English, and never left the ship.

@ Bus driver was under Official Secrets act, and passengers needed a security clearance to get past the first gate. It was run to allow the people in the facility to get transport to and from work at the facility, getting a bus service to add an extra route was cheaper than having to buy multiple buses and employ a fleet of people to run them. Not really a core part of making HEU and developing things that go boom big style. I wanted to go, but my clearance was the wrong type, not for that facility, even though I was able, under supervision, to read some of the reports about it, by somebody who was actually cleared for it. Most boring 50kg of archived drivel ever, it did not contain the info I was looking for at all, just endless meetings with nothing actually said, typical middle management making themselves appear useful.

Brake use depends heavily on drive style. Drive like you have a carton of eggs balancing on a small pole and not falling over they last forever. But drive in traffic hard, and the wear is going to be severe. Heavy front of the vehicle and it will wear anyway.
Did mine this last weekend, of course it is "as per sample", so go get the less common rotor diameter, and matching pads, and then take old off, clean caliper, support, hub and backing plate, and apply a thin film of rubber grease on the touch parts, and the hub and bolts, so that they have a little film to keep the rust from making them one. Pads I got are Ferodo, so guaranteed to last 100 000km, though the rotor will be destroyed by the time they wear out. Did put the little screw back in place, but only hand tight on the torx driver, not even a socket handle on it, as it will not fall out with the wheel in place.
Reason for replacing was I felt a slight shudder when slowing down from high speed, and then looked, and saw that, while there is half the pad still left, the rotors have worn a nice set of ridges, and thus the shudder. So off to the spares place, and get what they have, not ATE, which I wanted for pads and rotors, but off brand rotors and Ferodo pads, so I know that in 50 000km I will replace the rotors and the pads again, with the pads again showing no real wear. Old pads were OEM from GM/Isuzu, no idea which local supplier they use, but likely the OEM, looking at the construction, was Ferodo, as they, Girlock and ATE have the local market OEM part supply pretty much sewn up. Filters I use GUD or Fram, as they now are the same company, and I never had issues with the filters from them, but the others I have had issues with leaking and such.

The limiting item will be the final fuel pickup tank, whichever one is used for this, typically the centre tank. You will want to keep this one full as much as possible, but as the dive is generally something that is done with reduced power, after the high power climb to gain energy by both increasing velocity and altitude, and the zero G segments are accomplished by reducing thrust, allowing the aircraft to coast up and complete the rise and then fall to the recovery altitude, you do not need much fuel input, so the full tank will tend to have fuel flow mostly non vapour entrained to the fuel pickup screens, and then into the low pressure lift pump. Past there the system is pressurised, so the vapour will be condensed back down.
Hydraulic systems pretty much the ame, there generally are pressurised bladders used to maintain pressure anyway, and to supply peak demands that are beyond the pump capacity, so this will do the hydraulics, and, while they may get a bit of air entrained in the fluid, it will be bled out in normal operation on the flight back, and will certainly do so on the ground when pressure bleeds off and the bladder expands to fill the pressure reservoir full volume.
Toilets are going to have one way valves in there anyway, plus the seat itself has a valve that is only opened when you flush, though I would not flush in the zero G segments, as you will end up with a full coating of blue fluid, just like in heavy turbulence.
Pilots will have the seatbelts on, and will also be able to find that pen that some body lost last flight, as it floats past.

@toriless Very hard to kill a fig tree, they are tenacious, and even Roundup will not always work on them. Took 2 bottles applied direct to the root system growing in concrete, plus removing all the visible wood, to kill one. There is a bougainvillea growing quite comfortably near me, living at the top of a street light fixture, growing in the little gap between the steel pole and the lamp base. It is healthy, even flowering with nice purple leaves when I went past today. Street light still works as well. one tough plant that, also resistant to insecticides as well, plus a bear to trim down. I use a chainsaw, both a regular one and a long pole saw, to avoid getting all destroyed from the thorns when going in for the deeper branches. Garden service people were not exactly happy putting it on the truck though, those thorns go pretty well through most types of glove with no problem.

Well the mining of old dumps for gold, and the profitable extraction of copper, silver and sulphuric acid from the dumps, was also a SA thing, and the end result was also that large chunks of land, all now more or less in the middle of the gold reefs, was available, plus the residue from the recovery was pumped back into the pits, both filling in the old adits, and making the ground less prone to sinkholes forming, and also keeping the local water tables free of pollution. I remember all those mine dumps being there, but now almost all are gone, replaced by housing tracts. The actual god recovery was also, because of new methods over the old mercury extraction and flotation used, actually higher than the current virgin ore being mined, despite it being already processed, and the dumps were also easier to handle, seeing as the ore was already crushed and easy to handle. Of course, you also had a good amount of both mercury and other stuff recovered, as the mine dumps were used as a catch all dumping ground by the mines.

@renakunisaki I did do that, buying 25W golf ball lamps by the gross, and needing to replace them at least once a month as they burnt out. However the downlighters used good lamps, and as they were always slightly underrun the life was good. When the shop had the ceiling ripped out I found a few of the original stock Osram lamps in there, still working perfectly, though the reflector of them had basically become transparent, and quite a few had simply flaked completely off. 105 downlights, swapped out after a month from 50W to 20W, because the difference in energy use was considerable, and also you needed half the amount of AC unit to keep it cool. Even so there was a second AC unit installed, as the main one could not keep up with trying to cool the whole area.

@I_Do_Cars I have the non USA 1.6 5 speed manual one. Nice car, just service is not buying GM parts, but Daewoo, because it is really a Daewoo with GM badges. But a nice car, now 12 years old, and with a nice clean engine as well. Some time soon I will have to replace the clutch, but that is readily available by ordering for a Daewoo Lacetti. Nice comfortable car, no speed demon, but loves the open road, and keeping around the speed limit is around the most economical fuel use point. Just needs regular oil changes to have a long life, and yes I had to replace cam belt recently, because of a bolt that went down and damaged the outside of the belt. No idea where that came from, must have been left when the engine was overhauled at 130 000km because the exhaust place tried to do an EGR and cat delete, and failed. I got that right after a little work, finding what they broke, and fooling the EGR valve into thinking it was passing exhaust gas.

I had 3 cans of spray paint as standard in working on helicopters. First one was water displacement fluid, used on every part. Second was contact cleaner, used on connections. Third was matt black, used, with a piece of paper as mask, to touch up instrument panels. For corrosion control we used Tectyl, but the cans were not easy to get, but the 205l drums were all over, and if it would fit in the drum it would get dipped, then hung up over a galvanised steel pan, next to the drum, to drip dry. Larger in the pan and use a brush to cover it. I put entire instrument panels in that drum, then wiped them down to a clean surface, so that every pore was filled with anti corrosion compound, then would wire it up, put the gauges in, and put it back in service. Would not corrode then.

Funny about that just today play in a wheel. Looked at it, and was told new bearings recently. So easiest thing, undo the CV nut, pretty tight, then loosen it off, and knock CV loose. the tighten nut again, using long breaker bar ( but no pipe) and standing on it. Got near another turn on it, those bearings must not have seated fully initially. Put back and away it goes. Needs a list of other things, like sway arm bushes, shocks, saddles, valve cover gasket and a camshaft sensor. Those can all be done soon now, now it is running properly, and not a danger. Really needs new brakes, but they are still usable, and owner is going to go back to smaller rims, cheaper to replace the tyres when they wear.

You are wrong with the internal pressure switch in the condenser, it is normally run on the low pressure side, and is set to provide protection in the case of low refrigerant, switching off the compressor when the suction side pressure drops too low, from a loss of refrigerant. Then you do have a thermal cutout inside the compressor, that does break the full current, though better units also include an external overtemperature switch, turning off the compressor when it exceeds 120C case temperature, with the internal one operating around 140C. Better ones also include another switch in the high pressure side, turning off the compressor, typically with a non resettable trip, when pressure is too high, normally caused by the fan not running to move air over the fins, or the fins are clogged solid, and the high pressure side rises up in pressure to a very high pressure from the hot gas being in there.

As there are a few lawyers who had assets seized, they will be pushing the case. Hopefully the judge actually does sanction the person who signed the request, and properly punishes them. Banks as well no longer want to offer safety deposit boxes, so they now no longer do offer it, thus the market for private companies offering this service.
By the same logic the FBI used, you can then seize every vehicle, aircraft, bus, bicycle and scooter in a city, because some of them might have been used in a crime at some point. Same for every house, under the same logic.

Remember as default formatting a drive as ext2/3/4 (or ReiserFS, with the warning that there is no way to undelete on this file system) the owner of the newly formatted filesystem there is root, so you need to change ownership of the folder as root to be user 1000 (the default login user, normally you) before you can use it.
Formatting as FAT or NTFS does not do this, as these are non native Unix Linux file systems, they are mounted normally using FUSEFS, and many older distros could not read them, unless you added in a module to allow this, which was eventually included as part of the kernel by default. Also beware of compatability between different versions of EXT filesystem, older ones cannot read newer ones correctly, so you would need to use a compatible version, or format on the old system first, as the new one will read and write it correctly.

For the niche applications resistive heating in the outdoor unit, which can serve double duty in doing a defrost cycle while operating, would probably be a good thing, turn off outdoor fan and reduce heating draw, while ramping up the heaters till the outdoor coil is above freezing, then slowly start the fan while reducing heat. That at least will still ensure energy extraction from the air, and thus extra heat, and you could also have a vent panel that also flips, to allow the compressor cooling air to be directed to the coil, and not dumped to ambient, providing a useful amount of heat as well. Summer you dump that heat, keeping it away from the coil, but in winter you want that heat to go to the coil. Another way to grab that extra 5 degrees of differential, or an extra few percent on efficiency, as most compressors run hot, and have little to no cooling air flow over them, unless they are in a square block tower, where they get cooled by the hot condenser air, or warm up the outlet air.

People saying RADAR, you cannot see closer than a minimum distance with any RADAR system, simply because your transmit pulse is a defined length, and that, plus a guard time and the time it takes the TR switch to enable the receive path to receive the return signal, is going to be much more than 10 miles for most AC sets. Plus as well ground clutter will make detecting a single person on the ground near impossible, they are simply another bit of noise in a solid block of noise.
Yes airports have a secondary RADAR that shows the location of all aircraft, all vehicles and most objects on the field, but that also needs somebody to look at it, figure out which of the hundreds of returns is not an aircraft, a vehicle, a building, a light pole, an airport employee there legitimately, and then alert a security team to go and investigate. Often this display is solely in the ATC tower, used to guide aircraft on the ground, so the ATC is more concerned with aircraft on the ground, vehicles, and that there is no obstacles on the flight path. A person may not be visible on there, especially if there is a lot of clutter from things like approach lights, grass and probably drainage ditches, all of which obscure areas. Those aircrew vests also have metallised sections in them, so that they do show up on the ground RADAR as a signal, otherwise the person might not be visible.

Electric power failed when the keel broke, as that then disconnected the steam supply from the small steam plants that powered the electrical system, and also from the assorted bilge pumps that were doing their utmost to pump water out, and prolong the sinking. By that time the electrical crew had likely run out of rewireable fuses, and had simply started replacing them with the neutral links, as those also fit the fuse holders, but have a solid bar, in order to provide power to whatever parts of the electrical system were left. They probably saw the front part stop drawing power deck by deck, as the cables were snapped in the trunks as the ship flexed, and thus were the first to know, aside from the stoker gang who were still running the boilers, that the ship was tearing itself in half.
Those cables will still be there, as copper chloride deposits in the iron oxide, for millions of years, long after the wreck has been eaten away by the iron loving bacteria, and it is buried by slow accumulation of calcium carbonate silt from plankton. In a few million years, when that sea floor is uplifted as limestone, there might still be recognisable objects found, mostly glass and ceramic items, and the odd bits of the engine castings that did not get totally eaten before they got covered, and of course all the lead that was used to sheath the cables in the wiring trunks, which might still have the remains of the copper in them as well.

@DavesGarage Yes, it is great. As an aside TTL is really rugged, you will probably only find one or two failed gates, though more than likely your issue is open circuits, either cracked solder joints on the pins, or bad IC sockets that go intermittently open.
I have had an entire computer have a power supply issue, with the unregulated 14V being applied for a few hours to the 5V logic, 2 cascaded failures of the overvoltage crowbar not working any more, and something in the 5V regulator going bad. Of the 500 or so TTL IC's on the various boards, only one actually failed, a PM5403 quad open collector NAND gate. Easy to see once the board was pulled, the lid had unsoldered itself. The computer itself was still fully functional, just had a single detected fault, in that the self test light went out immediately. Guess what that IC controlled. All functional otherwise, even the 2708 PROMS were fine, along with the custom Intersil DAC in the 40 pin purple ceramic, and the Mostek MK4007 RAM chips.

@jimwheeler6094 Aircraft engines, at least the ones I was involved in, generally have a 10 hour run at varying power levels, up to full afterburner for 10 minutes, as part of testing after overhaul. Incidentally you really can only use full afterburner for 20 minutes, because by that point you have run out of all fuel in the tanks. 10 minutes in the test stand was close to 1200 gallons of fuel, and that test stand had it's own fuel delivery pipeline off the bulk tank farm to supply it. The in hanger fuel points took 10 minutes to fill up the plane from empty.
the same ground test is also done to all other engines, they get a good few hours of ground run before they even get put back in the aircraft, and a SOAP sample is taken before the oil is changed after that, so that any wear is detected before flying it. Then test flights after install, and more SOAP sampling.

@steveboverie9432 Who does the injection also is the thing, I learnt from a hard as nails registered nurse just how to administer injections, because she would swab the area, then get ready with the needle, and tap the area a few times with the swab, to get your skin and nerves used to sudden taps, and then slip the needle in instead. You would not notice it. She almost always was the one doing the pediatric work as well, because she would not cause any sudden pain to the infants and children, so they would not cry, and thus not stress the rest of the children in the line out either. Plus she always had a big bottle of sweets, that she gave to them afterwards, as reward. But i did see her inflict needed pain on some, giving them a teaching reminder.

Blowing gas, so even a new thermostat will not fix the problem, gas in the coolant, and no antifreeze, means it is blowing it out fast, which is a blown head. About the only thing you can do is a can of stop leak, and see if it slows down, but that engine needs a new head gasket on it, and possibly a skim, though it can have cracked already and need either a new head, or stitching together. VW was famous for making a 5 part head if you overheated, cracking between each cylinder.

@lawrencedoliveiro9104 Mostly due to them using ENG vans, with the high bandwidth video and audio being sent via a satellite link, so it has to go up to a Geosynchronous satellite, then back down to a ground station, then either via a terrestrial linkage, or more commonly, back up to the satellite and then down to the broadcaster studio. 4 trips to geo orbit right there, and thus the delay, so yes you will have delay.
Better will be if the reporter on scene actually does not have an ENG truck, but instead uses something like 2 cellular phones, one providing the video link and the audio, using a cheap bluetooth microphone paired to it, and the other phone in the pocket, receiving the studio talkback channel to a bluetooth or wired earpiece. Much lower latency, as all likely will be done via ground based cabling or links, but drawback is that it needs there to be a dependable local cellular network available, and for it not to be overloaded, and also not shaped for that call. you get cellular data plans that are guaranteed lower latency and higher priority, but not all carriers worldwide support the ability, and often you do not have a working cellular network, so the satellite link is the only option, as the whole lot, including the antenna, can be fitted into a pair of carryable suitcases, and deployed reasonably fast, though this then gives rise to the other acronym of ENG gear, being Easily Nicked Gear. Eye watering high prices for the equipment, and also for the connection per second, plus high monthly retainer costs, so they are not common.
When operational Starlink should make this lag a lot less, as it aims to only be a short hop up, then a few dozen bounces till it reaches a ground station.

Yes, ship out in a container, and sell offshore, using fake or modified paperwork of an existing vehicle, because so long as you pay the duty on the incoming side they will not care, and thus give you the ability to "legit" enter the VIN into the country, and make a massive profit selling the vehicle there. Once sold if it ever has warranty claim and comes back as stolen buyer is the one out of pocket, seller still has the money. Just have to do a few transfers to wipe the info off the title, and run odometer up a little, or sell into a market where manufacturer has little representation.
Your $100k stolen vehicle might cost you $30k to get it there, and pay the "legitimising" fees, but that $70k is pure profit then, and all offshore as well.

Main memory is all the address space (1024k on the original 8080 processor, 16M on the 80286, and more with each generation after). Low memory is all the space under 640k, as the memory from 640k to 1024k was reserved for add on card ROM images, memory mapped so the PC bios could use them, and the section just under the 1024k mark was reserved for the PC bios, as the processor reset and interrupt routines all expected ROM in there.
Very slow cheap ROM, almost always with one or more wait states on the memory bus so they could respond, with later on fast RAM being used to shadow the ROM, increasing speed. Then you also had to allow for this shadowing to have holes, as cards could have fast memory mapped regions as well, yet another set of things that could bite you, especially with the first network cards that had a 2k RAM to transfer data.
With the 80286 you has more than 1024k of memory, so all above 1024k was upper memory, and you could access this from programs via one of 2 methods, either have a call direct to there, but losing the original 8080 address features, or use the then brand new memory mapping unit in the 286 processor to bring in a chunk of this memory to appear to be in the area under 1024k, called paging.
Swapping between processor modes on the 286 and higher was done by calling a special register that changed from Real Mode ( 8080 compatible code and register wise) to Enhanced mode, allowing the full processor capabilities to be used. This does change some instructions in how they are executed, so to change back you have to reset the processor only, using a instruction sent to the keyboard controller, that also controlled address line A20 to force it low to disable the upper memory areas, and also reset the CPU, so it would restart, see that it had done a mode switch from the BIOS code, and restore all the registers, and carry on in real mode. There was a logic bug in that you could set A20 high, and have an extra 64k of memory still usable from the 8080 Real Mode, and not cause the program counter to overflow, giving a 64k block of high memory that you can use in Real mode directly, making programs run much faster without the slow switching to and from real mode ( you need to save all registers, do a very slow machine wise IO instruction and then halt while waiting for the keyboard controller to read the instruction, decode it, flip the appropriate bits on it's outputs, and then reset the processor, followed by the processor reading from slow ROM, seeing if a magic byte value is present, and then if so restoring all the registers back before finally doing a pop from the stack to get back to what it was doing before the context switch) and saving on the valuable 640k of main memory.
You eventually had so much of the MSDOS kernel and drivers that you could load either in upper memory or high memory that there were a few programs that needed the LOADFIX program, as they would crash, never expecting to actually be loaded with so low a real address, under 128k IIRC, and all loadfix did was fill the low memory from the original entry point to IIRC 150k, and then call the original program, so it ran from there, and free the memory again when the program exited.

Knew one of them in the 1990's, who, when asked how old he was, would reply maliciously "60", because if he admitted his age, he would be on pension, and he did not want to sit at home all the time. He worked harder than men a quarter of his age.
Every weekend, when we came down to the sea, we would bring back a few 2l bottles of sea water, which had to have, at the bottom of the bottle, at least 5cm of beach sand, as otherwise it could just be salt water. We had plenty of stories from him about his life, and how it was in the Great War.

At least this did not involve removing the engine to get to it. Oh yes you can see where the wires go to, but to get there you drop the engine out, and then remove a few minor parts, inlet, exhaust, couple of shields, then you can change it, only 2 bolts and a almost welded together connector, plus a bolt for the battery connection. Mercedes with the A class, where remove engine is standard, for things like changing oil filter and plugs. Undo 4 bolts and place engine in service position using MB special tool, or a jack and block of wood.

But he could sell it there easily, and the registration would be accepted. There is little international checking, only really on exotic cars, where the number of stolen ones is disproportionately high, because the stolen ones land up in a container within hours, being shipped out of country to areas with laxer laws. Vin clashes, and especially engine number clashes, are very common if you up the poolof vehicles to all around the planet, as the vehicle manufacturers only make sure that a VIN of a vehicle they produce for a market area, like NA, EU, Africa, ANZAC, South America, are going to be unique for that market. Engine numbers you are guaranteed they will have clashes, as that is often only a 5 digit serial number, and Isuzu makes more than that number per model in a year.

If you have a nuclear plant, you can use the waste heat to boil water, to desalinate it, though you will only boil off enough to double the salinity, for technical reasons, but this will still use the waste heat and produce all the fresh water the reactor needs, plus a lot more for export along with power. Not enough energy in the low temperature steam, you want steam at 300C plus to gain useful work, and will condense it down when it is at around 150C, which will still allow you to boil sea water, though as above, with less efficiency.
Not enough useful energy in that steam, which will be very wet, to actually do useful work, and you will be needing to use heat exchangers on the incoming salt water to both condense the reactor turbine steam, and the evaporated steam, so as to actually gain efficiency, by using the first heat exchanger to boil the water, and the second one to warm the incoming water a little, with a third one to cool the outgoing water and add some of the energy to incoming water, so you lessen the energy to get it to boiling, though the biggest heat need is to evaporate that sea water to a wet steam. Basically making your inlet water be at 90C, close to boiling, so you get maximum energy transfer, and you get 95C primary water out, which uses another heat exchanger to cool down to around 50C, for the run through the boilers again. Complex, lots of pumps but will give large amounts of reasonably low salt water, not going to be distilled, but definitely equal to river water in salts in it.

My one battery charger was made by GE around 1950, but still is working, after a few repairs and updates to put charge control in it, to not cook batteries. 3A average charge current. Also go another smaller GE with 1A charge rate, that is fine to keep a battery charged all the time. Modified a welder to make a DC fast charge, up to 50A for 30s, which is enough to bring a battery up to something useful.
Issue with the alternator is that the regulator is the wrong type, you have a few different ones that are used, from a plain dumb one that simply acts like an old 1980's alternator, to the more modern ones where the ECU is the thing that provides charge regulation, and varies a PWM signal to control voltage from the alternator, and battery charge. Yes been bitten by this as well, solution was to go to the dealership, and order the exactly right alternator, based on VIN of the vehicle, direct from Korea via the agents. They will give the right part, and i would say your daughter has a failed brush pack on the alternator, worn away. New brushes $1 by me, though for the one I needed a different brush, so bought the cheapest VAG clone, and ripped the brushes out of that.

Bolts are easy, plus the different lengths for steel versus alloy rims are hard to do in a stud form, either they stick out far, or are too short depending on the wheel type. Not much difference from each other, just that bolts at least have the wearing part easier to change, plus broken ones are, because the tension is now off them, are easy to remove, provided you have not left them on for ages to rust fast. Studs on the other hand are a PITA to change, especially when you have no clearance behind to remove them, and have to take a hub apart to do so. Smaller heads as well on them, so smaller diameter possible on the wheel boss, while still having enough strength and fatigue life to last.

Well, likely he had his personal car with insurance, probably same model and colour as the govt issue one. That way he does not hit any flags on the Uber systems, and just has to provide a pic every so often of the clean own car. So now he has what appears to be valid insurance and vehicle, just the driving is done in the govt vehicle, and pretty much every rider does not look at the plates, only make and colour, so easy enough. For deliveries even easier, he gets the food and such, and drives out to deliver, so nobody cares about the vehicle at all.

You will come across some 2 wire sensors that are polarity sensitive, notably some sensors that use active electronics inside the sensor, so best to make sure you always follow the wiring diagram for pin number to wire colour, just in case you run into one of those rare sensors. I have seen this in industrial sensors, where you get a lot of 2 wire sensors that are very much polarity sensitive, despite being 2 wire, and those are making their way into automotive as well, as they solve a lot of problems in cable routing, as the small signals are conditioned right in the sensor, making it possible to use a much cheaper wire in the loom, instead of a shielded one, saving time in the loom assembly and cost to make.

Another tip is to small the oil, you can tell if it has stop leak and seal fix in it, and if they added stop smoke, just from the smell, and the sticky feel when you separate 2 fingers that are in the oil. Those mask bad seals and worn rings for a short time, till you change the oil, or they stop working, hiding the problem. Also do the sale for the ATF or gearbox oil, you can smell burnt ATF, or see the distinct smell of burnt gear oil, and the additives added to make noise go away for a while. See that look at another vehicle, or offer lower price, because you will either be rebuilding an engine, or replacing it with a new one, along with transmission, in short order. Price will have to reflect that cost.
Also check brake fluid, and inside the reservoir, clean fluid, in a dirty sludgy stained bottle, says it was just changed recently, and probably just the fluid in the bottle, the dirt is still in the lines and cylinders. in the underside check look for rusted out brake and fuel lines as well, along with other rust damage, and any suspicious freshly coated areas, as that often is a case of paper and filler over rust, and hiding the rust damage without repairing it properly. Seen way too many with cardboard rubberised to the pan to cover the holes.

Yes but the bearing is only a tiny bit cheaper than the whole assembly, and once you take into account the 15 minutes of time to press it out and the new one in, it is cheaper to replace the whole thing. Yes doing it yourself the labour cost is lower, but Ray has to make a profit on the job, and the 30 minutes to swap versus spending 30 minutes on another billable job, is making replace the whole thing look a lot cheaper. I have done a repack on noisy ones, but once noisy the bearings are already toasted, but more grease from new will help with longer life. Bearing packer that gets the extra bit past the seals works well, especially on ZZ bearings where that is just a dust seal, and not so well on RR ones, where you might pop the seal getting more in.
Have done gearbox bearings, where the new ones came in as RR, and I removed the inner seal, so the gearbox oil could lubricate the bearing as well, much better life over the original. Those with an outer seal both got removed, so the seal got lubrication.

ss Mine go 5 years or 30 000 km, about half the recommended change interval of 7 years or 60 000km, so I do not have to worry too much. However as it is VW, and the second most common vehicle here, spares are both plentiful and quite cheap, and thus you have no real benefit of running till it is near failure. The tensioner actually costs more than the belt, and is also a change part. I am so thankful I do not drive GM, where they use the water pump as tensioner, and they are invariably rusted solid, or the bolts snap off in the block. With Ford and the CVH engine I had belt and water pump replacement down to a hour extra during service, mostly from making sure those bolts were nice and clean, and well lubricated. We did do a half hour change one afternoon, in a garage, after the pump had a bearing fail. 10 minutes to cool, 10 minutes till out, which was coincidentally the time it took the new pump to arrive from the other spares branch. They asked where the car was, and were surprised that the car, that pulled in 20 minutes ago, was the one needing the pump. Gasket compound on that new one was well cured, we still had 400km left to do that evening, and left with it still wet.

Most common method is to get a totalled vehicle, and take the VIN stickers off, complete with the panel area, and weld them into the stolen vehicle in the right locations, grind engine number off and restamp it, then take it and reregister it as "rebuilt", which gets you to a clear title. Yes they often will also swap the ECU and TCM, along with cluster module, and immobiliser (of course does not apply if it is a Hyundai or Kia in NA as that was a $10 cost saving measure to leave it out), but often these are damaged, so leave the originals in place.
Friend just bought a new to him from a dealer, and during the process I went along, plugged in the OBD reader, and verified the stored VIN in the ECU matched the one on the vehicle as well.

Well by me in South Africa the common phone box was a copy of that K6, but made in aluminium or coreten steel, with windows installed using common truck and caraval glass sizes and rubbers. Then there were a few oval fibreglass units, mostly indoors,, and then the last were steel with tempered glass (later polycarbonate, as that was a lot more vandal proof) panels. There is still one near me, vandalised of course, and non working. Yes I did use them a lot, with a few variants of phone instruments in them, from the grey coin operated ones, to the later electronic coin operated ones, and then the last generation ones that used coin or phone card, though the last versions tended to be card only, and nobody sells the cards any more, only using them to receive calls.

For the scammers I click to open the scammer in a new tab, then copy the URL to Steve ( or whichever channel they are scamming on), and on the scammer page click about, click the flag, and report them for impersonation. then you paste the channel being impersonated, and submit, and you get an automated response from YT ( great that) saying it has been reported. You can check the status around 3 days later, and normally the scammer is gone, slowing them down a little. Saves sending to Steve and overloading him, plus with a world wide audience the scammers get less time to scam, as most are in the far East working a 8 to 6 job scamming, with them hoping 1 in 100 will fall for it and send money via either Western Union, or other non refundable methods, "to pay postage", and never get anything.

@rodshoaf No, only paid 9 months of the year, they are required to use those spare 3 months to do little things like prepare lesson plans for the year, teach summer classes, do mandated training classes, do school activities. All of them they have to pay for themselves, and often the school district will only partly pay back the money, after around 5 to 6 moths of struggle, and also they get expected to do all marking and such at home, unpaid, and also are expected to do extracurricular activities as well, unpaid, and supply also all the equipment as well. Would you like to have a job where your bosses expect you to provide 60 pens a month, plus all your own paper for the documentation you have to give, plus also print them yourself, on your own computer. They will not give you a computer or printer, or will give you a non functional one that dates from when IBM was actually a big player in the home market, and they expect this 20 year old computer is perfect to use, even if it is broken.

Mine I did use a waterproof additive in the grout, plus used it on the walls before tiling, and in the tile adhesive. Lip by the shower door, and sealed with silicone as well, plus the weep holes in the premade unit. Of course no problem with mould and peeling wallpaper, as the entire building is concrete and brick, plus the bathroom is tiled. The original tiles were a bear to get off, as they were put in properly, back bagwashed with cement slurry, and then laid into a freshly plastered wall, followed by the rest of the room being plastered to the same thickness.
In general you just use a jackhammer to chip away the old tile glaze all over, paint with 2 coats of bonding liquid then place the new tiles over the top, because the old tiles only come off with the plaster and a bit of the brick surface. Old buildings, old building codes, the newer ones you just use a scraper and peel them off, if they did not already fall off.

My father, amongst his other things, was also an automotive engineer, and he swore blue streaks at automotive engineers for designs they did in the 1980's, with parts absolutely designed to fail. most of his automotive design was with heavy mining equipment, where a design point was to make things as easy to service and as robust as possible, because somebody will be doing this service a half mile underground, in a rock strewn section of tunnel. He did spend the last 30 years of his career though as civil engineer, designing and installing infrastructure to both mines and towns, like conveyors, factories and water and sewage treatment plants, then went into transport logistics for a large brewery, as that required a lot less travel, and paid better. Still needed that automotive engineer, as this included as well procurement and design of fleets, from the trucks and trailers, to the actual buildings they used. I still see trailers he designed in the 1980's, still in use, and still going strong, despite being designed to be at least 5 tons lighter than the competition ones, but with the same load capacity.

Should be in total under 0.5V, if more check for good connections and corrosion. Remember this includes both battery to alternator, and starter, plus the fusible links that are typically used, plus the ground cable from engine to frame, and the ground cable from frame to battery. most often engine ground, and battery to frame, is the one neglected, and often one is poor contact. Remove the chassis connection, clean the terminal lug, the bodywork there, and apply a thin film of grease ( white grease, dielectric grease, Vaseline, wheel bearing grease, or even gear oil or engine oil at last resort), and put the connection back, and make sure the nut is clean on the contact face as well. There are often TSB's about this, famous on GM products as they age, and covering multiple models and years. Same for the fusible links and multifuse units, undo, clean the contacts, retension for the plug in ones, and clean and reconnect both with a thin film of grease on all mating surfaces.

Easy to do, take some of the money and buy a totalled vehicle of the same, make, model and colour, and then cut out the VIN plate from it, and weld into the hot one. Grind off engine number and punch in the one from the wreck. Then take wreck and part out for scrap, cutting into pieces, and sell off good parts. Now take the clone and run it through 5 different states over a 4 month period, to muddy the title change history well, and sell to a dealership as trade in on one off the lot. Good tip is to use burner phones and fake ID when doing the transactions, but use real addresses for the registrations, in large cities.

M6y one is a feral, but took only one night to use a litter box. Mostly because first night he was locked up in a bathroom, only room with no problem to clean, and I was not going to drop off a hissing kitten new years eve, those go straight to the back and an injection. So went and got wet and dry cat food, and water in a bowl, and the next day got a used cat litter box, which was used straight off the bat. Still runs from people, except plays through the window, because that is safe. Goes out at night, but always runs back at noise. My not so little feral boi, who likes to sleep with me, and be with me.

Same here, though around 1999, with RH 5.2 as well, ordering the CD's from a small one person band, sent via post. Yes could download it, but hard on a 1400 modem, and likely to break. Ran well on a PC declared obsolete, because it ran Win98 too slowly, and which was replaced with a new 200MHz Pentium. So I got the old slot 1 100MHz unit, and installed RH on it. Worked out of the box, including the "welcome to Linux" speech saying the sound card, which had been iffy under Windows, working perfectly, and the CDROM drive working as well.

Yes Chernobyl was first and foremost a nuclear weapons production line, just made power as a by product. 3 mile was nothing really, but blown all in out by media and vested interests in coal, which incidentally emits more radiation uncontrolled than nuclear ever has. Fukushima was also an old design even when new, but built because it was considered export safe, and also the operations and management was very much done by having a pass the request up style, and then meet and discuss this for weeks, and not lose face, style of operation. You can make the reactors safer with modern designs, and also smaller modular ones are more reliable, especially if it is self contained, and needs little maintenance other than at a specialised facility, where you have the skilled people who will open it. Treat it like a boiler, which needs special operations to run, and it works well like that.

Funny enough the reason I have had my personal information leaked is, almost in every case, a government database with all the info needed to do full identity theft, and with either no security, or security by obscurity, with the info being accessible by simply running through the request ID in the URL, with again zero verification as to being a valid user. the others are mobile operators, and of course the same applies there, with multiple cases of fraud coming out from that data being out there.
Some of these companies seem to regard security as being "we got a lock from Masterlock on the door, it is secure", while not even building the walls of the data centre up around the door frame and roof.

You learn, eventually. Possibly to drive slower, put the snow tyres on, and to add a load of weight to the rear to help with traction. Incidentally that type of reinforced sign is now no longer legal, after a few incidents of them not breaking away, and people being killed by the sign pole penetrating the vehicle. So now they get protected by moving them further back, making them overhead, and putting barrier rails to slow down vehicles who hit that spot.
Did not help with the one I saw, where the idiot driver was speeding, hit the plastic barriers, smashed 100m of them, and then proceeded to punch the steel barrier rail right through the vehicle, including the driver. He had come past us about 15 minutes before, basically low flying, and decided to overtake the line of cars in a construction zone, where it was reduced to a single lane.

Disconnect is always needed for EV charger, as the breaker is only for cable protection, you need the disconnect out by the EVSE side, to allow it to be locked out for maintenance. For use with a building power supply easiest method is to simply install consumer side prepayment meters, where your main meter still is read by the utility, and the sub meter is handled by a company who will simply supply you with credits on the meter, so that you pay, the meter unlocks, and you get use of power, and the money is deposited to the main account. Common on houses with a main meter, and a few tenants with separate service, where each has their own meter, and they pay what they use.
As to chargers, a car has a very low duty cycle, in that you typically use it for 3 or 4 hours a typical day, and thus the rest of the time is free for charging, which is actually better battery life wise. A motor that runs all the time is not a car, it is a heavy duty truck, which has entirely different pricing and use, and note not a small truck, but something that has over 10 tyres, and you have a fifth wheel trailer on the back all the time, driving 8 hours a day. That engine is rated for use as a generator, not like a car engine.

Tractor also you have to remember you pay for the basic tractor, anything else is an add on, from the tyres you put on it, to the software you pay annual fees for that enable things on the tractor that are already there, like a GPS, the ability to keep speed, and to drive the extra equipment you need to add to it to make it more than a glorified dumpster mover.
Buy JD and you have to stay JD, because they deliberately make the new model incompatible with the old model, just so you now have to sell all the old stuff you paid top dollar for, because it does not work with your new tractor. Not that it is different function wise, just that it will no longer fit, or the tractor software does not recognise it. Same plug, same power connections, but because it is the wrong version, it will not work.

Easy enough to happen. Rental is late, call centre calls them, no reply, and leaves message that car needs to be returned, or it will be classed as stolen. Bills the card on file each day for rental, so driver sees this, so does not call them back, because hey still paying for it. Then end of trip, drops off at the local office, drops keys in the lock box, and flies off. Meanwhile police charge has been entered into the PD computer as "suspected stolen", and they see it as stolen, tow and let court figure out.
Meanwhile the local office comes in, sees the car in return, keys in lockbox, fills up the tank and bills card on file, but does nothing further to look at file, and puts back into rental inventory. Then rented out again, and a few cycles before the car goes and parks where a PD car with ANPR, and with this listed as suspected stolen, is going to flag it. Then towed, and owner notified, same call centre again, getting email from PD about recovery of this reported vehicle, but not actually verifying that the vehicle was not stolen, and simply entered in file for vehicle. Then local office, far away from corporate, does not check. and this CF ensues.

I remember one day walking in town, and seeing 2 boy racers at a light, next to a truck tractor, belonging to the railways. Nothing special about the truck, just the tractor, Mercedes Benz, with the then standard Atlantis Diesel engine and Eaton box. Boy racers were in the then new VW Golf GTI Mk1, and a new 330i BMW. They were revving engine, waiting for the green. On the green the truck driver floored it and left rubber, screaming that ADE engine up to 2200RPM red line, spinning all 8 rear tyres, and leaving the GTI and BMW in the dust. He was at the next light, and stopping, before they were even half way down the street. Both boy racers simply slunked around the corner, quietly and slowly, thrashed by what looked like any old truck. Yes they likely would have beaten the truck if the next light was 1km away, but at 300m they got eaten badly.
Also Steve, in his Mk1 GTI, put money on a fighter pilot he could beat him in a quarter mile (500m) drag race. So one night while we were on night ops, they lined up, pilot on the runway, Steve on the taxi way next to it. On the flag off they both go, GTI easily being in front for the first 200m, jet on full afterburner and 20 tons mass, with extra fuel in 3 drop tanks, far behind. 300m and the jet is catching up fast, 400m and the jet passes the GTI, then flat taps at just under 200kph (Steve had a ticket or two showing he could get to there), with the jet putting a lot of forward stick to hold it onto the runway. 500m and the pilot pulled back hard, just left the undercarriage down for an extra minute while limiting speed, so as to allow it to cool down before selecting wheels up. Steve lost his money.

88 sheets is a roll in the USA, that is robbery. Here by me the legal requirement to retail toilet paper is that a single ply roll must have 500 full sheets, and a double ply, or more ply roll, must have 350 sheets. No wonder the US had a TP shortage if your average roll is one third of the standard the rest of the planet (as they all base theirs on the EU ISO specs for the most part) mandates. Even for commercial grades, where there is the same specificed sheet count, and for continuous rolls there is a minimum length per roll. The Chinese paper with that US spec does not sell, even at half the price, though admittedly that is also so poor it will fall apart looking at it.
But then, I bought TP December,, the annual bulk buy, which cost me the equivalent of $20 for 48 rolls. Never needed to panic buy during the pandemic, I had plenty as I had gotten 3 packs on special, the months before the world went TP crazy.

Tip for the garage dig a small trench around the outside, about a spade deep, and a spade wide. Then order for yourself 5 20kg/50lb bags of borax, which is very cheap. Then pour into the trench, a nice even layer about fingertip deep, and close it up. Will keep any of them from moving in, and also kill kill any ants as well. Same for the house. Also works to kill fleas and roaches. Will, after doing it, have you finding them all over for a few days, kicking on their backs. Cheap, relatively non toxic, though not pet safe, but works well.

@notstonks20 Possibly, old unit that is the ship of Thesus, where every part has now been changed, but the new parts still use the old thread patterns. At least those threads will be easy to replace, as the insert kits probably are cheap, as they have been sitting on a shelf since the 1970's.
I have a few sets like that, came in the metal case instead of the plastic ones the metric use, and bought for around a tenth the price as well. Just going to be a bear getting new inserts for them, the only supplier only keeps a few around at a time, so included them with other orders, to get better pricing, slowly. Some of the kits had a date on them that was older than me.

Guess version 2 should include into the mass calculations the addition of a small set of doppler radar sensors, and use them during the landing, probably doing a disable of the data from them below 50m, because of dust. The 3 radars will be giving a X drift, a Y drift and an altitude above terrain, along with closing rate. That will allow them to remove residual error from the IMU units, which likely led to the rolling over, as the tiny errors accumulated during the journey, and rounding errors led to the ground drift likely being excessive, and thus it landed with a significant drift, which caused it to tumble.

@rubiconnn Only up till about the last 10 years, as manufacturers are designing the vehicle to start to fall apart just about the time the warranty period is over, so that you are then on the treadmill of buying ever more spare parts to keep it running. They want minimal failures during the time they have to pay, and for the vehicle to disintegrate a few months after that, in the hopes you will buy a new one from them.
Of course with the increasing use of insane balloon payments at the end of the HP period, most people are stuck with that, as the balance due is going to be way more than the vehicle is worth, so they have to trade it in at the manufacturer's dealers and buy another on the same terms, while the dealership is able to get what they can out of the trade in as a sale, as they now have a guaranteed income from you for the next 5/6/7/8 years for service, as you need that to keep the loan from becoming full outstanding balance due.

I had some come in that were washed, leaving only the MICR ink, the signature and nothing else. Then they printed everything, including the background, and submitted it to the bank for cash. Bank paid it out, and we got this cheque, but the book keeper saw that this cheque had been issued, paid for a larger amount, but had not yet been returned to us for reconciliation, yet had been cashed a second time. When we got it it was a good fake at first, but the give aways was that the background, looking under a magnifier, had inkjet dots to get the background colour right, and also had some slight smudges around the MICR info, where the old offset printed Pantone background was still visible, plus they had used as template the wrong cheque printing company, as the bank had 2 suppliers who made the cheque books for them. Still had the same book it had been issued from, and also an error that had been made, which left a sample cheque that had been cancelled in the book, in the same sequence number. Bank ate the cost, seeing as they were the ones who had cashed the same cheque twice, when the sequence number should have been repeated in around 5 years based on use. Never heard anything about the police case I opened, which is pretty much standard.

Those fuses are stamped out of a sheet, and the metal used is aluminium, which has a low melting point, or a tin zinc alloy with a similar low melting point. Then they get inserted in the plastic housing. The melted metal is from oxide forming between the legs of the fuse and the edge of the brass contact in the housing. The cure is to remove all the fuses, and then clean down there with a thin needle file, to make a new clean surface, followed by a thin coat of dielectric grease to keep it from tarnish, then the same on the fuse blades as well. Needle file set, and the single sided flat file, one wipe down per side, and then a thin coat of the grease on a piece of thin card cut to fit, and same on the fuse. Then put in, and check the contacts are what is gripping, and not the plastic, and retension the contacts as needed to get a good grip on the fuse blade.

@mgaus Remember this hits the actual people, not the immortal company. The people who made the decisions pay for it, not the company. Just like there are sections of the OHS acts that lay the fines specifically on a person, not the company, and also that a lot of certifications are linked to a person, and move with them. So like a person who causes a wrongful death in a company, even when they can claim they were acting under orders, will be the one to pay as well, with the company also getting the fine, and the managers above that person also getting fined personally. Put the penalty on those who did it, and the ones who enabled it, as otherwise it is merely considered a cost of business, and thus taken as a small risk to the company profit. Fining the company merely means they fire workers, or do not give them an increase, but still pay shareholders.

Designed when a calculator was actually a person who you gave the problem to, and they did all the long hand maths to get a result to the specified accuracy. Normally 2, so that a discrepancy would result in them both checking and doing it again.
Also when all the accounting was done in a large room, with lots of desks with scribes, each one using a perfect copperplate script to enter information in ledgers, and where each one was audited either weekly or monthly, to make sure that all the data was correctly entered. Black ink in wells, with the auditor using a separate green ink well to do their additions, or corrections.
Still have some original title deeds from the 1890's, where the original is in copperplate, and later revisions are in different handwriting, with later ones typed.

More like no idea about the group that took the wrecker truck, hog tied the driver, and left him naked on the freeway, zip tied to a post, and the truck was never found, though there was a wreck that was found burnt out in the desert a year later, just nothing identifiable on it. Absolutely no idea at all, terrible thing to have happen to such an upstanding member of the community, especially the superglue applied to his butt cheeks, and his hands, attaching them to the cheeks as well. That and the syrup, and that nest of fire ants next to the post as well.

@sprockkets Only ever had one unit that actually came with a heater for the compressor, and that was because it was run really hard, with inlet suction at 0C, for a split AC. It killed compressors, and eventually just charged it to around 5C at suction, and it ran a lot better. After all discharge temperature was around 70C on the high side, dropping to 40C when the hot liquid left it, so it was definitely running flat out. Put a large liquid line drier on it to give more liquid volume and a little more restriction as well, fixed cap tubes and not wanting to do the manufacturers designing for them. Left the heater off then, it was a lot happier, just pulling a nice puddle of water from the air instead of the ice block.

Thermal camera on wheel rotor you first need to hit it with a quick spray of paint, no real issue as to colour, as the shiny metal reflects back the temerature of the environment, not the metal temperature.
Biggest use is to run through the fuse box, with all loads on, like lights, AC, fan on high, hazards on, brakes on, defroster on. That then will show up all the hot fuses, and if any have poor contact they will be a lot hotter, so simply remove them, clean the legs with 320 grit water paper, and check the socket, and put back, and it will run cooler again.

Way too many in the harbour as well of people driving off the edges of piers. Harbour solved it by painting a double yellow line, then fined them for crossing the yellow line, plus the cost of recovering the vehicle. You still had the idiots who drove into the harbour cranes, or parked on the rail lines they travel on. Crane operator cannot see the wheels, so just drives the car out of the way. The sign on the crane tells that if the horn is sounding the crane will be moving, and to be aware of the motion. Just like the woman who drove past the flashing signs and the boom saying train coming, and got dragged 300m down the line, by the train doing 5kph. Railways simply kept that case going till she ran out of money, and refused to pay a cent, and had a counterclaim for damage to the track, engine and the lost time. Most expensive is the lost time, penalties for late shipments can easily be 8 figure amounts.

@WrenchingWithKenny By me I see vehicles all the time with bald tyres, and other obvious defects. Not even only old cars, plenty of newish luxury models where the driver only puts fuel in, because they have learnt that from running out a few times. They do not even know what fuel to use, because the garages are all, by legislation, full service. You can bet as well that that vehicle very likely is still running on the original factory oil as well, and they will run it till either the lease is up, or it breaks down on them. Then tow and complain about how unreliable the vehicle is. When you see a soccer mom, drinking her famous Seattle iced frappe with one hand, other on the phone doing her social media, with sparks coming from the 4 bald tyres, and her doing all this at 100plus in a residential area, with 3 children in the car, none wearing seat belts , or even in child seats, you know to stay out of the way, and hope you are not involved in her accident, which will invariable not be her fault, even if she drove into a brick wall.

I had an avionics computer come in with an odd issue, power on self test completed within a hundreth of a second, not the regular 2 seconds. Tested, and, while it was running fine, and all the internal checks showed it was functional, and it was completing it's tasks correctly, it was just behaving "odd". Opened the case (84 M4x12 capscrews, I had bought a cordless screwdriver long before, and worn out the original gearbox, it was on the upgraded Black and Decker powder metal gears for later models) and went through the power supply, measuring voltages. -21V ok, -19V ok, -15V ok, -12V ok, 12V ok, 15V ok. then the last rail, 5V, meter did a range adjust, which it should not have to do on the 10V range, on that Racal Dana meter. 5V rail was showing 16V, the unregulated input bus voltage. Power off, and start with the power supply, replacing every part in that 5V rail, including the resistors on the board, and also the over voltage crowbar circuit, that should have blown the 10A fuse on the transformer rectifier board next door to it.
All new parts, from zener diodes, power transistors, resistors, capacitors, driver transistors, the failed SCR, and the diodes that fed power to the system self test for power system, on the next board. then power on, still have that self test execute too fast. Pull out all cards, and replace with spares, then test again, perfect, so a card fault. Then start replacing card by card, till I get to a card that, amongst other things, contains the system memory, IC's that are even rarer than KIM1 rom, a MK3007 serial memory pair. Also has the self test circuitry in it, and looking at the card I can see one of the surface mounted devices looks darker.
Put a spare card in there, the rest of the original cards back, and power on, self test executes perfectly. Run diagnostics, check all the analogue side inputs and outputs, and put all 84 capscrews back in, and box it and send it back out. Kind of needed, I had 11 behind me in a rack awaiting repairs, held up by needing million dollar power supplies. Never got to them before leaving, and anyway the lot went into a destruction session 2 years later on, as the airframes were demilled for the new owners.
Looked at the card, and the only part, of the hundreds of exotic, unobtanium, and covered by some secret acts, parts in there (the stored program, in Intel Hex, on punched tape, that did all the calculation and a lot of logic decodes, using a board of 1k EPROMS) that did fail from having however many hours of 16V applied, was a single quad open collector (ironically rated for 30V on that open collector) gate, where only 2 of the gates were used, along with a resistor, to combine all the logic to drive the 12V relay, that drove that self test light.

Probably had been repaired on the line, but had not been correctly calibrated again after repair. The software in the cell will compensate for slow wear in the unit, but a repair, putting in new parts, needs a calibration routine done to ensure that all the welds are in the correct locations, at the correct clamping force, and at the correct current. New parts probably removed slop, that had allowed it before to weld correctly, but the new parts resulted in welds that, because of no slop, were now made in air.

I put one in a good number of years ago, because otherwise your car will be stolen. Now it went into a repair shop after it got into an accident, and my friend, who's car it was, forgot to tell them about how to disarm this. After 2 weeks he collected, and found they had been pushing the vehicle up a 2 flight ramp every day, because they had called an automotive electrician out, and he could not figure out the immobiliser. He got in, and started it, and they could not figure out how, because we had discarded the reed switch commonly used, as thieves simply went around with a strong magnet off a broken speaker to try to find them, and instead had a hard to press switch hidden under the carpet in the tunnel. Immobilier itself I used the full 2m of loom it came with, and matched the original tape used on the loom, and cut and pliced, soldered connections all round, into the main loom near fuse box, and simply taped this extra wire into the loom with matching black tape, all the way to the passenger side kick panel, where the control box vanished into a hole in the frame, and was held up there with some foam wrap, and looked like a factory installed loom and module. By me you cannot insure a car unless it comes with a security system, unlike the USA, and even a 1980 Toyota Corolla had to have a minimum spec system. You do not have the easy to steal Hyundai and Kia issue at all, simply because the insurance companies will not finance such a vehicle, so all come with a decent immobiliser.
Though if it is over a certain price, or is one of the top 10 all time stolen ones, which includes the Toyota pick up, all variants, any 1 ton pick up, all larger Toyota sedans, and the biggest seller, VW, you are required to put in at least one tracking device, and often you will get companies putting in at least 3 of them.

Around me they had pay and display, but of course those machines were regularly vandalised, broken into and simply stolen, so if you park by one that is out of order, you just photograph the broken machine, and if you get a ticket you go to the metro police and contest it, and 9 out of 10 times with the ticket and the photo of the broken machine they simply cancel the ticket. now the only thing they do is put fines for expired license disk, parking in a loading zone, or double parking, and the officers also take photos of the vehicle and the ticket on the windscreen as well, so they can use it if they are in court. Exceeding time is no longer enforced, along with speeding, which is a whole other tale of incompetence.

That is why your typical X ray facility and dental office has a room that is lined floors, walls, roof and doors with lead sheet, to attenuate this. Also the windows into it are made with lead glass, which does the same, and the doors are lead lined inside.
thing is, the actual clothing they use on you is not lead, but depleted Uranium in a large amount of cases, as it is a better absorber, and thus a lighter mass for the same protection. Coated wire woven into a cloth, 2 layers, so few gaps, and more flexible as well. Does need special handling for recycling though, which is why you typically hand in the old when you buy the new.

Finland, Switzerland and Sweden also has the same fines based on income. There have been higher fines levied, and the person appealed, but had to pay.
Funny enough in Sweden my father was pulled over by a traffic cop for speeding. Now the traffic cop spoke no English, and my father's German was very rusty ( last spoken in 1945), so the officer got an English speaker on the radio. They explained that he had been speeding in the rental car, and asked him where he was going, because that road ran to the Arctic circle. On finding he was going the wrong way, they spoke to the officer, and he was instructed to lead my father to his hotel. So, right in front of a "No U Turn" sign, they did a U turn, and then started off south, and the cop had lights and siren on, and after a while they were doing around 160kph, on the road marked 80kph, where my father had been doing 90kph. Slowed down only a little going into Stockholm, and when at the hotel the cop instructed, via the hotel porter, that my father should stay in the city, and not drive on the freeway, where he can get lost. No fine at all, and he was leaving the next day, so simply left the car at the hotel, who was also an agency for the rental company.
He was also told the next day, slightly hung over, that he was a big spender in the casino, due to the Swedish liquor laws that forbade the selling of alcohol after a certain time, except in hotels where there were foreigners in the bar. So in the bar, people kept buying him drinks, and he was in the casino playing roulette. Few small chips, and he was on a winning small streak, chips not getting much more, just different colours. Around 2AM he figured he needed some sleep, and went to bed, tipping all those chips to all the hotel employees he saw. Next day found that he had been playing at the end with $50k and $100k chips, and had given a few of the staff nearly $200k as a tip.

Plus there are legal requirements, written into both building and fire codes, that breaker boxes must be accessible at all times, in case of emergency, so power can be disconnected.Might only have a button you press hard, that disconnects the entire panel and you need tools and keys to turn it back on, but the law states the panel has to be both signposted, and accessible at all times. Even in your home that applies, and you find out the expensive way when you come to sell, and find that that fancy kitchen cupboard you installed has to be ripped out, because you built the breaker box in, and it is no longer able to be serviced.

Durham, had any vehicles in that have met the can opener bridge? Or just you doing a drive through of the bridge itself.
Yes the bottom spring is there to keep the element pressed up to the base, but in the middle is the bypass valve, and up top the rubber is the non return valve on the inlet. Using a different filter than the original is fine, provided it is the correct seal diameter and correct thread. You also do not want to downgrade, so longer or fatter is usable, and if you do not have a spec for valves having them is better for cold starts after overnight, where the filter without will drain back down, and thus oil pressure takes a few turns longer of the engine to build up. There are a lot of filters that are otherwise identical in all respects, just the difference being if they have inlet and outlet valves, and there are cross reference charts saying the lowest version is obsolete, and the others that are a fit and suitable replacement.
On my VW I used different filters than OE, as the OE does not come with anything other than the bypass, so I used ones that fit, but have both inlet and outlet valves. Z88, the most common filter by me, to Z147 or Z157, both fitting, just one fatter and shorter than the other, but same area of filter material in them. Older cars you find filters are obsolete, but the modern spin on filter that replaces it is worlds better performance wise, or is supplied by the dealership as a replacement, improving filter ability, or improving cold start performance.

Depends when it was dropped off. After hours towing company is liable, but if dealership accepted it from tow during hours, and signed for it in some form or the other, it does then fall on them. They however are negligent, as the insurance companies all have the not small print that the insured party must ensure that all due care and appropriate control measures are taken with regards to the policy, so at a minimum the polict will include the stock on hand, which is likely insured, must be locked up securely at night, and that they must have adequate protection in place, not an open lot with no fence or gate, and no cameras on it.

Amazon still uses USPS to deliver outside of the larger metro areas, because USPS still has a mandate federally to deliver mail there, and even if it is not profitable to send a post van 200 miles to deliver 10 letters, 50 parcels, and collect 5 return letters, they still have to do it. But large high density areas Amazon can use contractors for cheaper than USPS rates, no union dues, no overhead of having full time staff, no requirements to fund pensions for the next 50 years out of current revenue. So that is why you see USPS not delivering parcels, and the fleets of Amazon branded trucks, each driven by an "independent contractor", who does not get the luxury of being able to decide work hours, work route, work time at all, but must follow a rigid set of targets delivered by the app on the phone, otherwise getting penalised for it. Funny enough the set hours, set route and set tasks to complete in order apply only to employees, but they are still not employees, and can be dropped at a whim.
By me post is difficult, delivery is perhaps once every week, and finding a post office is getting to be hard, as all that are in rented premises are closed, due to non payment of rent, utilities and such, and the deductions for tax, pension, medical and such have been taken off, but not paid over, for a few years now. Also staff are being paid late, and those being retrenched are also only being paid a part of the amount each month, and that often being late as well. No overtime, no raises, longer hours, no resources, invoices printed on lottery paper, as that is the only paper around, and bring your own pen and staples, plus paper, if you need something certified. Letters are improving though, only 2 months to the same post office, and parcels are now under a year to be delivered. However they still keep to their motto of "We Deliver, Whatever We do not take" as well.

So, if you are in an area that is prone to flooding and storm damage, get out of there. If you are in an area with high elevation, and does not get storm surges and flooding, get yourself stocked up, put storm shutters on, and strap down things that will blow away, and help those who are going to get washed out. It would be good to keep water, spare fuel, a generator and fuel, and probably also a month's worth of dry food there, along with a few spare mattresses and bedding, plus some old clothing, because you are going to be a shining beacon of salvation to the area. Let the neighbours move cars to high ground, and lett them stay with you as well.
Above all don't be a Karen. Be kind, be polite, and keep a pack of candles handy, along with waterproof matches. Plus a few packs of tea candles, because that, plus a bit of stiff wire, can be used to heat a can of beans in emergency.

Or when they take those state DNA databases, and decide to get money by selling to insurance companies. So now your insurer tells you that, because of your DNA, they are not going to give you life cover, because there is a 51% chance you will die early, or they will not cover your pension, because your genes say you will live longer than the statistical age, and they do not want to have to pay out more money than what you put in in the first place, hurting their profit. Or employers not hiring, because you have a chance of developing some diseases, or will need some medication in the future, so they do not hire, because that will cause healthcare costs to go up.

@krissteel4074 Slow train yes you survive, but the car is a mangled wreck 500m down the line. Over 50kph on the train side the car is shredded into confetti for 4km down the line, as the train is stopping with full emergency braking. Almost nobody survives that except the train driver, protected by the armoured glass front and the 10cm steel armour plate the front is made from.
The iron ore train here has a stopping distance, under normal conditions of 60km, and the guard in the rear engine knows if he is told to jump to just jump, because the front driver will already have baled out. Emergency stop, detrimental to both the rail and the tyres of the train, is 30km.
Train drivers get counseling after each incident, and can actually be placed on full pension after these, irrespective of age. Foot Plate union looks after the members.

@richardroland4365 Yes, and if you show up in court often the officer is not there, so the DPP will simply either drop the case, or reduce the ticket amount to half. You can also appeal before, most of the time the issuing department will do a reduction, depending on how many are there that day to pay. Got to have a lot of chats with them, as i was the nominated person that paid tickets, though my name and identity was not associated with the vehicles. Always ran mine and my friends and family when i had to go there, just in case one of them had a ticket on the way. No speeding tickets though have been issued by me for the last 15 years, as the municipality supply chain rules meant the sole accredited certification issuer could no longer be used, so all the training lapsed, all the equipment calibration lapsed, and the metro was forced to pay back 5 years worth of camera fines. now everybody travels at whatever speed they are comfortable with, except on 10 roads that fall under the provincial authority, who still trap the crap out on those roads.

A20 handling was done by sending a magic byte to the keyboard controller, which is another Intel CPU, a 8048 single chip computer. You wrote to it, and read from it, using IO space, so you would write the A20 flip code to it, and the 8048 would get the IO write on the bus, decode it and then set the A20 output accordingly, and then reset the CPU. The output of the 8048 was logic ANDed with the CPU line, so that you could have A20 be either always low, or follow the CPU state. IO operations always occurred at bus speed, so were a lot slower than the CPU clock, so you would have dozens of wait states while the IO write occurred, and then a halt was executed, while the keyboard controller executed the instruction and flipped it's output pins in sequence. Then reset brought the CPU out of halt. Keyboard controller only has 2k of ROM and 256 bytes of RAM, and at the most ran at 12MHz.
The 80386 had a separate pin going back into the CPU that fed back the state of A20, so the CPU cache logic could see the status of the line, and thus not corrupt memory by attempting to write out cached data with the A20 line disabled, and even later on the A20 handler was integrated into the CPU as well, when the keyboard interface was brought into the chipset.
You still get some pins on the South Bridge that are multipurpose, in that they can have what they do assigned, and the logic of the 8048 programming is still there in most part, even to the point that some chipsets still have the cassette interface available as part of the silicon, though to use the pins would mean sacrificing the use they have now, but the code is still there, just masked off by the "magic registers" that the BIOS writes to to set up the chipset on power up, and which are in general write only registers, or which return status data back on read.

True on the F150, but the worst is the bog standard vehicle, but has the aftermarket knobbly all terrain wheels on it, with the tyres that make that noise. Yet the most off road they do is onto the pavement to park in a shopping mall, right by the door, because they do not want to walk from the parking.
Yes that fuel line is single use only, because the install makes it conform, and there is not enough wall thickness to allow it to be reused. It likely will soon enough be made with proper fittings and a flexible hose by the aftermarket, to use the correct hydraulic fittings that are meant to be reused, instead of the use once style, but the use once one for Kia is a lot cheaper to assemble, low cost steel seamless tube rated for the pressure, and then cold formed to make the flare ends. Can also probably find an alternative that has the flare ends crimped on the pipe, giving a thick wall flare, that is reusable, but those also cost more to make as opposed to reusing the brake line flaring tool, which will still seal under lower pressure, but not at the 2000PSI the GDI engine has to operate at.

@RainmanRaysRepairs LOL, better than a narrow minded "name the party" person. And yes very likely those corn dogs do suck, mostly because they are both mass made, and also probably have sat in a warmer for 2 days already. Should come visit by me, you can find out that fuel station convenience stores can actually have good food, because here the biggest differentiation for fuel stations is the store, due to fuel price, and full service, being regulated. Only thing they compete on is location and service. Best coffee I ever had, being made to the same standard, was at a fuel station, getting there for the first brew of the day, in clean cups, and a totally clean brew machine. They also do pretty good fast food as well.

Had a similar thing happen, hit unmarked roadworks in the rain, and totalled the tyre. Got the claim form, and submitted with location of the roadworks, and the bill for new tyre and alignment. 3 months later got 80% back in settlement.
Those rims are not totalled, there are plenty of places that will take them, straighten them and reweld them up, and then X-ray them for any damage. Probably worth doing as a set of spare rims, though would not do track racing on them afterwards, just use as general driving rims. But yes, painted tyres and massive rims are expensive to maintain, both from the cost of the rubber and from the damage they can have happen to them with potholes.

Friend got one of those dongles for his car. Plugged it into the blue one, which is a Proton Savvy AMT, a whole 0.9l NA engine and AMT gearbox. That could not exceed any speed limit, and also would not brake hard either. plus also was driven possibly a day a week. Got great scores that way.
For the fish toss in a cabbage heart, they will absolutely love you for that, and eat it up in a few hours. Lived in a rental where there was a pool that was unused, tossed in a few cheap Koi, and a pair of goldfish, plus some mollies. Now they are monster fish, and the owner still enjoys them, now they have bred a few times, making long finned koi, plus he also has a few resident kingfishers, a heron and a fish eagle coming every so often to visit and get a snack. He feeds the fish dog pellets, and the odd whole cabbage as well.

@tommussington8330 By me the harbour will connect up to the ship for power, they keep a few transformers in stock on trailers, and all of them have a standard 11kV input, as that is what the cranes run off, so easy to add on to the existing cabling. Then they can supply the ship, small will get 400VAC up to 1000A, after that they use higher voltage according to the ship specs. No plug and socket, a cable pulled up by a crane, and then clamped to the ship, and fed into a power panel on the deck, where there are terminals to accept the lugs on the cable. Then close the cover, and energise from harbour side, and then from ship side, and pay the bill before the harbour disconnects you, as the transformers have input side meters on them. You pay for both power used, and for peak kVA, so the ship engineers really are careful in sequencing loading as they switch over, both ways, as the ship side power plant is not as capable as the country grid.
Harbour also has some really big portable diesel gensets, in case a ship docks away from a power connection, or for temporary power in say a non powered area.

you might not want to do hard boiled eggs to the military spec either. Start with a 200l Regethermic cooking pot, clean and dry, and turned to upright position. Pour in 50l of cold water, and also a 5kg bag of salt. Then turn pot on to high. Start loading eggs, from the boxes of 60 dozen that you got, till the pot is full, typically 3 boxes of eggs to get there. When full, wait till the pot is boiling vigorously, and start a 20 minute timer. After 20 minutes, turn off the pot, and start to unload the pot, turning as needed to reach the eggs lower down, and place the now boiled eggs back on the trays, and back into the cardboard boxes. When finished and packed, allow to cool to room temperature, and place in the walk in fridge till needed.
If you are lucky you got those from the top of the pot, having only been boiled for up to an hour, and possibly still edible. Unlucky you got those from the bottom, which generally were black once peeled, and almost totally inedible. Those eggs also would bounce, even when tossed out the windows of the bus we had, and we also discovered that they would indeed go through a windscreen as well. then they wondered why there were so few of us that would eat breakfast or dinner there, though every day we got a packed lunch, as we were going 80km away to a training facility, that officially half of which did not exist, despite the massive concrete structure being visible outside the windows on one side, with the equally massive wall and bank between us as well.

Funny thing is here, not in the Netherlands, there is a very strong tradition of smoking the happy plant, and it is almost legal, or at least there is a lot of turning a blind eye to having it for medicinal purposes, and a very strong movement to have it declared as not illegal. Seeing as it is very common to find it growing wild, there is a lot of it around, and it does form a significant part of some rural areas for income in an otherwise poor place by growing it.
Was getting a delivery last week, and the driver and loaders, from upcountry, were sniffing the air and commenting they like this city, as they could smell the happy plant, from people just walking past randomly smoking it.

Going to guess the fair next year will either not be held, or will in no way have the 4H auction at all, and will very likely have a whole new set of directors and staff as well. At a minimum they are on for a false police report, and likely also for stock theft as well, in that they had no reason to handle the goat at all, plus likely will be paying as well for the therapy needed for this 9 year old, till she is "sufficiently healed", which can be a cost they will have to pay till she is dead, at a minimum, and will be unable to actually contest either, as the therapy is considered confidential.
Figure on a 6 figure payout, with probably the entire board also resigning, and the one who issued the report taking a plea bargain and a fine, along with civil restitution as well.

Yes, and as the vacuum cleaner is a bog standard Karcher unit the vacuum pump assembly is also a very cheap item, and easy to replace. Just a non standard bucket with the added mesh inside and the media removal port. But the rest looks like off the shelf, so the wheels, which are always the first thing to go on these, are a very cheap and easy fix. Pop off the broken one, and press on the new ones. Plus also get a spare filter, as that one will get dirty with carbon build up, and they are washable, but having a spare one around means no downtime while it sits in a bucket of engine degreaser overnight, and then is left to dry for a day.
Ray should get a set of them to keep, because, in a garage use, they wear fast. But buying another identical Karcher will also have as a bonus the tools it comes with, which includes the crevice tool, which is ideal to remove the media in the inlet, after a little work with a plastic welder to make it a little shorter and skinnier, and it plus right on the hose end. Plus also can be used to clean engines, and cars, unlike blowing air and sending stuff flying, it pulls it all into the bag.

@perwestermark8920 Plus also updates tend to fragment the disk, and even a SSD will suffer from that, as doing a block read can take place at the full SATA bus speed of 6G/s, and be complete almost instantly, with the requested file blocks all being correctly there in order, and then no need to do time consuming DMA block operations to make it fit into contiguous mamory, simply blast the block direct. If the file is fragmented you need to do multiple reads, part of a block every time, but still needing to move the entire block into a cache, and then DMA to move it, and then read next block fragment, and DMA again to move the bit you need. You cannot do multiple block reads easily and have them be monotonic, so instead lots of small reads line up to grab what could have been a single read.
Not a fault of the SSD, which moves data around on itself with no real care about LBA per block, but the reads and writes must take place over the single channel. Thus slower reads, as multiple commands are needed, and also you sit with much more context switching per CPU, as each core has to swap out what is in L1 cache to L2 to check the process, and then send a command to the glacial slow main memory to execute, and do this hundreds of times, instead of tens of times, as each read cycle needs 2 context swaps, and slow memory and IO reads consume thousands of clock ticks for nothing.

@forestmcneir3325 Yes but they already knew how to build engines, and thus knew how to make the steel alloys and aluminium parts needed, plus the instrumentation they already had in great part. Simple enough design, designed in great part for ease of assembly and to loose tolerances, so that many separate manufacturers could put the parts out, thus easier to copy as well, simply because small errors in a large amount of the unit are not a concern.
When you get to high temperature exotic alloys for turbine engines this becomes harder, because knowing the composition is not useful unless you also know how you make it, because those are grown in a specific way, and the alloy you start with when molten is not the same one you end up with when finished.
the Germans wanted these alloys to develop fighters in WWII, but could not make them in large volume, so went with steels instead they could make, which limited both operating envelope, fuel economy and engine life considerably. Thus the engine power was only half that desired, fuel use was doubled, and engine life was 25 hours. All because steel softens around 850C, so no parts could operate above that. modern materials run at 1200C for thousands of hours with only minimal issues and regular inspection.

@tactileslut Here by me they attach a barcode with a lookup for the clearance price, and yes often enough I have had to have a supervisor do an override on the price because the scanner got the non reduced barcode first, then scanned the reduced price second as a different item. Another store simply has a sticker, different colour each day, that they attach to indicate 50% off the marked price, and the tellers simply press the override button before scanning the item. Before they needed a supervisor swipe, but decided that this was killing supervisor efficiency, as they literally ended up running at a single checkout speed across the entire store. Cameras all over though, 2 per teller, one looking right at the till, and the other at the money drawer, to see the buttons being pressed and the cash bills entering.

Very slippery slope that, soon it will be filtering everything, including the school itself, because it might have a bit of something that somebody somewhere finds offensive, so it gets filtered out. Better to actually be a parent, and teach your children, and be a little more involved with what they are doing, rather than simply put them in the corner and ignored. Used to occur before the widespread use of Internet when they got copies of those scandalous magazines, You, Scope, and those scandalous books that the library should ban, like Lady Chatterlies lover, Shakespeare, 1984, the entire encyclopedia, the Bible and Quran along with the Torah, because all of those have either had images, text, or thoughts, that somebody considered to be impure at some time. Ban them all, including all children's books, because some might be offensive. Then all adult books as well, because some are not suitable for children.

Yes, but this was not lent out, it was sent for a contractually agreed upon service, put there by the manufacturer, in that they have a service schedule in the book, and the dealerships stamp this book. Not lent out, rather the dealership was doing a contracted operation for the owner, and also assuming liability for damage to the vehicle on premises or while under their direct control. Even though they have a waiver in the paperwork this case is going to hinge on the dealership not excising correct control over the vehicle in premises, and either by negligence, or by deliberate action, causing the incident.

Vacuum cleaner I took one of the nozzles and cut it down, then used epoxy to attach a piece of thick walled PVC hose to it, so you have a flexible and bendable nozzle to reach into tight places. Diameter inside a little bigger than the width of the nozzle, and it was around 30cm 1 foot long, so it reached into tight places. Was great for removing all sorts of gunk, and was a good nozzle. Washed it, and the hose, with engine degreaser after using to remove blobs of grease and such, so the hose would not be sticky, though you can buy the hose in 30 foot bulk packs, so if it needs replacing easy to fut a new length off the roll and toss the old one away.

Well done on upgrading away from blow up rims to something you can get locally, with brakes that actually work. Would drain the diff and refill while you are waiting, at lest keep the sludge and water from causing further damage. Fill with cheap gear oil, and run it for 30 minutes when you are ready, then drain and refill with the right oil.
Engine wise first thing I would do, before removal, is put a new filter on there, as a clogged filter can cause many issues, depending on what moves to where in it, and it either being full of water so the float blocks the outlet and prevents the pump from getting fuel, to it being clogged with dirt from the tank, and the bacterial sludge building up to clog the lift pump. Would suggest while engine is out to dump the fuel tank contents totally, and clean inside the tank, as the inside is very likely to be nice and full of biofilm and sludge. But yes with the engine with all seals leaking, best to pull it out (at least you have the right tools there to do so, plus a crane as well to make life easier) and replace every thing that says seal on it. Would also recommend replacing transmission fluid while it is out, as that will make it almost behave like new, and clean out the hydraulic oil tank, because you can bet it has a thick coal dust sludge in there as well. Diff getting water in is easy, the breathers are upside down, or are missing or cracked, or somebody was overusing a power washer. And yes new bolts for the shackles and suspension are a good idea.

Had that flight once with a military aircraft, we needed all 12km of runway to take off, and were in ground effect for around 30km before airspeed was high enough, and enough fuel had been burned off, to actually start to climb out of it. Altitude, 41C outdoor air temp, and full load. I remember seeing the entire 30km with the tree tops seemingly just within reaching distence. Landing was totally different, you could not tell, till the pilot announced reverse thrust, that the plane was on the ground, unlike the other 2 ahead, where we did see, then hear, them land with a slight crosswind.

Well, I have separate scanners and printers, but I did not buy the scanners, but picked them up off the ewaste pile. As to the refill cartridges, yes, and the refill in general has more ink/toner than the original one, simply because the refill actually fills the cartridge to the correct level, unlike OEM, where they fill to just pass a IEC page print test. Proved it regularly, where an original cartridge would barely get past 1000 pages printed before showing empty, while the same refilled cartridge (send in and get the same one back a week later, with new toner, new drum if needed and new wiper) would typically give the empty display at around 1500 pages of the same print mix.
Refill is also typically a third of the retail cost of the original, and around half the cost of wholesale as well. when looking at new or new to me printers I always look up the cartridge number and the refill cost, and simply do not choose those which are not refillable (more the DRM chip is not yet cracked, or not changeable, over any other reason) in the decision. Does mean I have stripped a good number of inkjets, because the cartridges are way too expensive for the amount of use, and if I need colour prints I go to the local shop and get it printed there for 10c per page. Last time it was a canvas print, on A2 canvas, so it was going to be them anyway.
Yes I have a colour printer, but it is going to be turned to scrap, because turning on a Tektronix/Xerox Phasor 360 costs $600 in wax, and I got this printer for free as well.

Never really had PC LOAD LETTER, more PC LOAD A4, seeing as the default paper size on non US localised printers is set to A4 paper, and only on paper trays that are unassigned, so only really the stack of paper trays under the printer on HP, just after you place the printer on them, and before you either use the computer, or navigate the arcane menu structure on the front panel, to tell them you are either putting A4, A5, DL Envelope, A4 transparency, or A4 letterhead into the appropriate paper tray.

Bypass filter with only 2 lines, oil from pump, and oil return to block. Needs to have a third line to return the bypassed and filtered oil to the sump, because all that does is have 2 filters in parallel, so in reality you can put 2 of the finer filters in, and still get full flow, as the drop across them will be a lot lower due to the lower flow. Plus really needs as well a differential pressure switch or gauge, to light up and show you time to replace the filter, before you get low oil flow and pressure in the engine. Does need calibration, using a graph of flow across the filter versus blockage, or using minimum oil pressure at idle versus turn off pressure of the oil light, so that when drop gets within 5PSI of turning the oil light on you get a light to change filters.

$11k worth of tickets is easy if you travel through the town regularly, like say a salesperson, or a truck driver, and get sent a postal ticket every time for some reason or the other, either for speeding, changing lane incorrectly, or any of a myriad of other reasons. Hard to fight when the ticket might show up a month later, for a camera offense, and you have no real way to either disprove or correct your action. 2 dozen $500 tickets for going 20 over the limit, all taken just past the line where you are required to obey the limit, or where the sign is obscured by foliage, and thus you cannot see it, showing up 2 months later will be a good chunk of that. sign that says, well out of town, on the same road that you can do 55 on legally, but the section leading to town, same width, same fencing, same everything else, just has had a limit of 25 imposed on it, with a single sign, that all who live in the town know of, and where the camera is. One ticket going in, one going out.

Funny enough when you go to the optometrist there are a few who have a CT scanner in the office, which is tabletop size, and which is able, after around 20 minutes of imaging through your pupil and the front of your eye, build up a remarkably well detailed image of the structure inside your eye.
Includes the retina, all the blood vessels, the cornea and the lenses themselves, along with the pupil, and also the different layers inside the vitreous humour as well. Amongst it's abilities it can also be used to make a contactless measuring for a custom contact lens, as well as determine your optical script to a very high accuracy, as it knows all of the optical paths involved, and can calculate the required correction as well, even if it involves the lenses themselves not actually having simple curvatures on them.

If you need $200k for a second freezer, and those ultra cool ultra low temperature freezers can easily exceed that price, even for the "small volume, low cost" unit, used, and approach multi million dollars, for the ones you can walk into, with the appropriate antarctic grade clothing. Where is the money to come from, if your entire research budget, which had to cover all costs, including staff and operations, for a year, was $100k total.

Extraction good luck, I had the one done, 20 years after the first dentist had wanted to yank that tooth out, and went to a surgeon, after my dentist looked, saw it was not going to come easy, curved roots and impacted, and made the appointment. Hospital, went, got the second opinion, and the Monday after went in for the 20 minutes of work with a grinder on the bone. All in all 2 hours there, and walked out drooling, and feeling no pain. Got my lift back home, and only felt pain the next afternoon when I woke up.
Paid cash, and even so it was under $200 for the work, with my dentist giving the exam on the house, normally $40, as I went back after a month to get the check up. Last time I went to hospital great service, just got what I called the $300 bottles of water, plus the co pays for the CT and MRI.

How about a drunk driver who parked on the roof of a house, not the first house off the edge of that hill, but the second one. 2 floor house as well, so the easiest way to get the vehicle off the remains of the roof was to push it over the edge, and down the 6m drop to the ground below, where a wrecker was able to drag it out the driveway, on the roof, to the waiting lowbed. First house undamaged, aside from missing a fence, some windows broken by the flying debris, and a nasty gouge in the retaining wall top, but the second house required both a new roof, a new drive, and a lot of interior repairs as well. Driver uninjured, was both too drunk, and too high, to notice. Also uninsured, not his vehicle, borrowed relatives car for the night.

Manufacturers want all the data because they can sell it for a profit. They know who the owner is, have the address details, and then know where they work, where thy shop, where the kids go to school, what stations the listen to, when they listen. This is to them very valuable information, which they can make a profit on even after selling the vehicle, and so long as the vehicle is running this is a profit centre. Plus they can update the vehicle remotely, reducing performance "for safety", to persuade you to trade it in to them for a new one again.

Yes standard in aviation, where you sample every 100 hours or so, and test to see long term changes. But there as well oil is often changed on run time basis, especially as the oil system covers the entire aircraft, and you need 300l or so of it to change it out. But with 300l, and it moving through a few filters at a good rate, plus cooling off and not being cooked, it does last well. Small aircraft you are changing piston engine oil every 50 hours anyway, because it will be well toasted, and those engines are not cheap to repair, plus not exactly easy to pull over if it fails. You put that oil in and it looks like treacle cold, but hot it runs like water.

@Dubanx Yes but most do pull a good chunk of data to use as evidence, and as routine run a search routine looking for credit card data, which is a standard form of record, for sale on the dark web, as a nice source of income while waiting for the main payout. They often sell the bulk record along with the number of cards, as that often is worth more, as it allows easier ways to get higher limits on the cards, as they can claa in to a call centre, imitate the person, having all the details needed to pass authentication, and thus get a limit increase, or a new card sent to them to use by a mule, to get things that you need a valid card for.

The one manufacturer who decided to go with no head gaskets, and simply make the cylinder and valves as a unit was Deutz, whose engines are still in use world wide. Drawbacks are machining them is hard, and you have to compromise on weight, unless you use a cast in sleeve, or use a very high silicon alloy. But the issue is the machining needs specialised tools, though it does mean you can fix a failed cylinder as a single unit. Was common on aero engines as well, with the high compression that came from them needing to have maximum power. Biggest drawback is that you now have to have space for the hold down bolts per cylinder, making the engine longer, and you really benefit with over square cylinder designs to make machining easier. And yes works best with air cooling, as the casting is so much easier to make, though with modern 3D machining you can likely make lost styrene moulds, that are light and accurate enough to get water cooling into them, with reliable performance. Would be perfect to make a small ultra high compression turbo diesel with, you can get high boost and only have ring blow by to worry about.

Saw one today, same crank no start. But also water damage, so they are going to have to clean all modules, connectors and hope they get all the water out of them, otherwise the vehicle, like a few thousand, straight off the Toyota assembly line, are destined for the crusher from flood damage. They were flooded, in many cases to roof height, no way to fix other than replace entire electrical loom and ECU, and replace all fluids as well, along with complete interior.

Standard braking on older caravans, because of the mass. Electric brakes never really took off by me, the only thing that has powered trailer brakes other than trucks are pickups with fifth wheels, where there the converter installs an air compressor and tank in the pickup, and the trailer has a pneumatic set of brake actuators, and a proportional valve tied into the regular hydraulic brake system, with an in cab parking brake for the trailer added on. Works really well, and is very effective, and the regular truck trailer mechanics can fix them with no problem, standard drums and S cam units, just a lot smaller than the truck version, and based off a Toyota drum and hub, so parts are not an issue anywhere in Africa for it.

Still plenty of those running around by me, in various stages of body ventilation. All the way from being near showroom condition, to those held together with body putty, to those that are rust in close formation, but still the engine and drivetrain are going, even if the whine of the diff is loud enough to let you hear it coming a few blocks away, and the stop at the fuel pump is to fill up the oil, and check the fuel, because the gauge stopped working in 1999, and ever since then the standard has been to have a 5l oil in the cab, and another 5l with diesel or petrol for the tank.

Your split using has multiple capillary tubes feeding the indoor unit coil, with a directional valve to provide a restriction in the flow depending on direction, so that you get better efficiency in the different cycles. There is another restriction in the outdoor unit, so the line leading in is a cool liquid at low pressure, instead of a warm liquid at high pressure, reducing the volume of refrigerant needed. This restrictor is also varied according to flow, acting as the expansion device in heat mode, and pressure reduction in cooling mode.
The coil outside is a lot larger in area, so the unit is optimised for cooling the indoors, but in heat mode the larger coil allows longer run time before defrost, though the heating capacity is lower than cooling, but as you typically are not removing latent heat of condensation it all evens out, the airflow is too fast to allow much to condense. Typically the units meant for heat pump operation and the regular non heat units use the same control boards, and simply have a few bits set in the microcontroller to tell operation mode, though often the board is the same, just with a different terminal block, or non used terminals. Outdoor unit is simpler, only with a single control line to turn fan and compressor on together, and with no sensor wires to give outdoor coil temperature.
Heat pumps you will have with the inverter a control board, first thing to fail, and you will find it is NOT covered with the typical 5/10 year warranty, on the compressor alone, on inverter units. The non inverter heat pumps are almost as efficient, and with a control board that is inside the indoor unit, and only a relay outside to control the compressor, with the fan speeds controlled by 2 or 3 wires, and then a control for the reversing valve (power the valve to make the unit heat, default to cool otherwise), and then only a inlet air temperature sensor and perhaps a coil temperature sensor half way along the coil, where the refrigerant is changing phase from liquid to gas. Indoor unit has the same sensors, inlet air temperature, and coil temperature.
These determine operating mode, the indoor ones in cooling will stop the unit cooling down when the coil starts to freeze up, from either too low airflow or too humid, and the outside ones will dial back the cooling if the refrigerant is getting too hot. In heat mode the same, though the freeze sensing is more important.
In the climate I live in heat pumps, though pretty much the standard, almost never get used to heat, so the valves often will seize up in place, and then the units will have strange faults, as the tiny volume of refrigerant in the non used valve heats up and moves the spool in it slightly, causing the compressor to leak refrigerant from outlet to inlet. Inverter units tend to be damaged from power surges, and the outdoor unit circuit boards are also prone to failing, as they are exposed to the hostile environment, and run either cooked or frozen. Not covered apart from the regular unit warranty, and you almost never will change a compressor under warranty, as the manufacturers will either insist on the board changed with the compressor, or will scrap the unit, as the outdoor unit coils will likely be almost totally destroyed before that 5/10 year period is up. Inverter board failure will probably burn out the compressor on one coil as it fails, and you will have a fight for the warranty.

@LadyViolet1 USA is not exactly friendly for public transit, and who can afford to pay every day for Uber or a cab, if they are already working on minimum wage. Rather fix the problem, tell them with the payment plan you will not suspend, so long as they are at least attempting to make the payments.
What you say is that if you are getting a traffic ticket, the police will come and toss you into jail till it is paid up, then will also take everything you own for the jail costs, and will keep you in there till you either die, or have, at 1c per day, paid off that $30 fine. If you die they will sue all your family for the remaining cost, and the cost of the funeral as well.

Still see a few of the Niva's here in South Africa, they were quite popular as an alternative 4x4 that was cheap. Advantager one owner said was that he could drive through bushes instead of around like the guys with the Toyotas, Nissans, Landies and Isuzu's, simply because at the cost, around 10% of any of the others brand new, who cared about a few pinstripes extra on the vehicle. Plus the toolkit fitted, along with the full size spare and the starting handle, in the engine bay as well, along with extra oil, baling wire, a hammer and a carpet, so your knees did not get sore fixing it.

Would say the blame is more on the ISP's that have long been known to overstate the bandwidth of connections, and deliver slow speed to all customers at peak load. they all say you have X bandwidth when you subscribe, but also that at peak hours you are lucky if you get 1% of that, as they oversubscribe customers with regards to upstream bandwidth. Netflix has, due to them having agreements with edge providers like Cloudflare, and also having dedicated hardware at lots of locations close to customers, the ability to deliver all the bandwidth needed, and be able to serve all the customers the data, but the ISP's have, in general, not actually done anything to improve their own networks to deliver, despite having received lots of Federal monies to do so over the decades, they simply took it, used it as shareholder bonus payouts, and have invested the bare minimum to keep the network running at some level.
You can sue Netflix, but in reality the one who is responsible is the ISP that provided that last mile of connectivity, they are the ones that had the problems trying to serve 100k 4k data streams, over a network that struggles with serving 10k 360p standard definition TV signals in the first place, as the fight likely was not sent by Netflix as separate streams to all the subscribers on a network segment, but as a multicast stream that any of the decoders and computers could receive, if it were not for the network itself having old hardware, long since paid for, and long obsolete as well, by a few generations as well, even in the slow churn that is telecoms, where 10 year hardware life is the norm.

@gierrah $30 drop could also be that, when they collected the old appliances, they also read the meter as well, and did an actual estimation off the bill. Most electric meters are read a few times a year, by me quarterly, and the bills in the interim are all estimated consumption, and if the reading does not fall within 10% of the estimate it will be tossed out, and wait for the next billing cycle read to see if there is still this difference.
Had a unit be empty for 6 months and the new tenant moved in (landlord has to have the bill in their name, not the tenant, so prepaid is common in rental properties here, either separate company or municipal, for both water and electricity), and after a month the meter got read, and they came to investigate the reading, as it was too low after 2 readings. Explained to the reader that this was because it stood empty for 2 months, with no electric use, as it was turned off at the consumer unit. He saw the seals on the metro meter were intact, and took the reading as accurate, and the billing was adjusted on the next month.
$30 drop could easily be that they went on holiday for a week, and turned most appliances off, along with not cooking with electric cooker, or using AC or heater, which would make that sort of difference to the bill, especially if it was read a month before, and this drop was a good fraction of average use.

I think this did spread across a lot of the networks connected to it as well, because they all used the same equipment, and tended to use the same versions of software, in order to make them interoperate correctly. I do remember that hitting by me in South Africa, but it was not exactly an inconvenience, as the network drop was during the evening, and by the beginning of business the next day it was updated, and as well a lot of the exchanges used older firmware, so that while international links were out, along with a lot of the trunk lines, the older areas were still running correctly, and could connect calls still. The ones who did not notice it at all were those using manual exchanges, of which there were still a fair number, dealing with small customer volume large area sections, where the standard was a party line, or only 500 phone lines in a single town or two, so you had an operator still there.

@vueport99 They actually work better if you use less detergent. I generally use a third of the "manufacturer recommended" dose, and find that the residue left is a lot less. My first washing machine was an old original Hoover twin tub, which is still sold (though now it is 99% plastic parts instead of steel), which was replaced after a few years of good service with another used machine, an AEG Lavamat. 30 years after the AEG was made, it finally was not economical to repair, though the parts were still available, but more expensive than the LG top loader that replaced it. A lot lighter as well, and that LG did around 15 years of service, before it also needed a new main gearbox, also available, but again almost the price (trade price) of a new machine. So it went out, and the new one is also locally made by me, from Defy.
Hoover was probably older than me when I got it on auction, but having fixed many of them over the years, my mother loved them, and me and my father repaired them always, getting the spare parts from the Hoover authorised agent, as the pattern parts were not much cheaper, and much lower quality. We also had a Hoover upright vacuum, which all we could tell, as the records were destroyed in WWII by a bomb, was that it was made around 1938 in Wales, at the Hoover factory. Used till the main casting finally cracked, which was no longer available as spare part, while all the other parts, including even the labels, were still available as genuine parts.

30 odd starts with no run will take any battery out to below start level, especially if the car has been sitting for a while, and the battery already was low from not running. Newish clean battery, though checking electrolyte level would also help, and topping up, but a nice equalising charge will work wonders on it. At least GM on my car did a lot of work on battery maintenance, it does a top up after starting, and then drops down to an equalising charge, and every few cycles does a desulphating charge, though I do have to watch electrolyte level and top up. Sealed for life battery just means it fails outside warranty, because the cells are all dry.

Easiest to just say the DA was going from the docket, and did not look closely at any evidence, and relied on the police doing shoddy investigation work. Plate came back to a non local male, car was similar model, police investigation closed. No actual looking at evidence, actual comparing photo off video and DMV details, and no actual care in the investigation. He has a very strong case to both have a civil claim against the dept for wrongful arrest, and also to request as a minimal compensation expunging of all records of the case, so that any background check, and his annual renewal, will come back as if this has never occurred. Plus costs, and an admonishment to the local PD and DA that they need to investigate cases properly before bringing them to trial.

Really cheap one is around $10, which will read codes, read monitor readiness, and show live data. Monochrome LCD, and sold by a good number of places, and a good enough unit that you can leave in the car all the time.
But yes a really good set of procedures, which are applicable to all vehicles, even worth doing if all you are doing is renting it for a week from one of the rental companies, to at least make sure you are getting a vehicle that is functional, and where you will not be dinged for damage when returning it, that was there, but not noticed, or noted on the sheet, when you signed for it.

Helicopters tend to avoid negative G for noise abatement purposes. Heck of a noise as the rotors hit the tail if you pull negative G past a point. Some helicopter designs include in the tail a heavy steel cutter bar, designed so that you get a very audible warning, as it chews the tips off the main rotor blades, that what you are doing is not a good idea. Yes you will need all new rotor blades, very expensive, and a good pit of panel work to fix the hole cut in the tail rotor, but still cheaper than losing the airframe.
Do remember having a flight with some really stressed out pilots, who had spent 3 hours turning in circles to calibrate the magnetic compasses after a replacement, and I took the flight back instead of driving on the tractor. Sitting in the cabin, door open, legs out and holding to the strap, with the sky below my feet, and the ocean visible through the rotor blades, as they were doing barrel rolls in this 16 ton helicopter. Yes it could lift cargo, 16 tons max at sea level, and if you could fit it inside, it would carry it.

@wolfgangpreier9160 The original 747 inertial measuring unit had 2 gyro assemblies for each axis, and would run if one of each failed. However that was not considered reliable, so there are 2 IMU assemblies, both located by the CG of the aircraft by the wing root. These then form the stable platform on which the acellarometers are mounted, and then the navigation computers, 2 again, each using the data from the 2 IMU sent to them, with each having it's own acellarometers and angle sensors. They then are correlated and displayed, and each checks the other. A very good system, just that you need to have the aircraft powered up on the ground, at a precise location, normally nose wheel parked on a paint dot, and the other wheel bogies on a set of painted lines, which were entered into the system as a known waypoint. Then sit there for a half hour while the computer sits and calculates drift for you, compensating for the drift of the earth rotating, the orbit of the earth around the sun, and the drift of the sun orbiting around the galaxy. Also the drift of the platforms as well, as they get slewed to have that as the initial level, and keep it for the powered up portion of flight. No vibration, no loading of the aircraft in any way, which makes it hard to keep it accurate.
GPS is an augmentation, but as a single system cannot be said to be redundant, and fault that takes out the antenna will stop it working, and there are not many locations for the antennas either, as the GPS receiver calculates the position of the antenna, so it has to be mounted on top of the aircraft, in a spot above the wing root and the CG. Also power levels are low, the individual satellites only have a 500W power budget or so for the transmitter, which has to cover a good chunk of the planet, and thus the received power is very low, well below the noise, and only recovered by using complex mathematics to reconstruct it. Spoofing has a receiver that gets the area signals, and then keeps a rough lock on them, but retransmits up to the target location a signal that is stronger, but which slowly is shifted in time, so as to fool the receiver into thinking the stronger signal is the real one, and the position it is giving is valid.

Which is why so many of those model panels have been recalled over the years, as they get dangerous as they age. Not helped by the 110V mains, as that means you have to have high current flow for power use. Australia and NZ use the same thickness and dimension in the contacts on their plugs, but there you have a max current of 10A on most sockets, which is 2.3kW, while the USA runs 15A to get 1.5kW only, and if you need more you have to use a different plug, while Aus has a larger one, still fitting the 10A plug, that allows 15A, so allowing 3kW of power draw. The panels there generally do not catch fire.

Funny enough the first time I went to a casino, I actually went there illegally. As the casino, to skirt around the rules of no gambling, drinking or scantily clad women who might make people think the kerk is wrong, was in a fiction called a homeland. Created as a fiction to allow some rights, (and yes the family farm was expropriated to make up part of one), and as military we were not allowed to leave the country, though there was no border post, and the sign was right by the entrance to the casino you were entering another country, albiet one not recognised by any others. We went on a whim, and scraped up enough to pay the parking, and around $5 each to go inside.
Inside, play the slots, buy the overpriced drinks a bit, but unable to draw money to go to the "shows" we left after around 2 hours, when I realised I was walking out with $5, and had bought drinks for all, so basically the dasino had been free.
Next time the same a few years later, different casino, different homeland, and right by the sea, and again I went there with the money I was going to waste, and left cards at home. Made that a rule to do any casino from then, leave cards at home, and take enough cash with to pay all the bills, and when the cash is gone you are also gone. Now legal, and 5 minutes down the road, and have not been there for the last decade, and that was only to go to the cinema there, as that is about the only surviving cinema around, the rest are long gone, and way overpriced for what you get.

I got some from the Post office, telling i have a parcel to collect, and that there is a fee due. Not even going to bother, because the post office is bankrupt, and them having the money to pay a SMS gateway to actually send the messages, when they cannot even pay the staff, and have not even paid over the income tax, medical and pension deductions for the last few years, because they simply do not have the money. Also been paying staff late, sometimes months later, and not paying bills either. Retrenched staff not being paid either, so there is no way they actually will send a SMS asking you to pay for a parcel, because nobody will use them to deliver any more.

The car records onboard, but does not make it available unless you plug in a USB drive in the car in the socket inside the glove box. It only keeps info till the space is needed to record again, generally a month or so, depending on how much activity there is. If the owner wants an external copy they need to plug in a high capacity USB drive, and then can copy the info over.
Very heavy handed approach, as they can easily get hold of the owner, as the registration will have a phone number, and the owners almost always have the app active on the phone as well. Plus the DMV will have an address and such for the current owner as well.
Are they also going to look for other vehicles with dashcams in them, either a dedicated one, or a GPS with dashcam, or an over mirror one, and impound them, break into them, and then look at the footage to see if it is evidence. most municipal buses and school buses also have cameras on board, are they going to impound them as well, along with seizing the camera equipment of any business around a crime scene, and then keeping them to auction off under Civil Asset forfeiture, as the vehicle, camera, business, is suspected of a crime, and is being held till they prove they are innocent.
These vehicles that are taken, are they impounded correctly, and checked that the battery does not go flat, because a Tesla battery that goes into failsafe mode, due to low charge, will need replacement, and if it sits for 3 months it will be stone dead, needing a new low voltage battery at a minimum, and you might need a replacement high voltage battery pack, and fuses as well, as the car will disable itself for safety, especially if it has been stored in a hot area, and has been running AC to cool down the battery packs, or cold where it has to heat them.
Are the police going to pay for a rental during this time, are they going to pay the insurance, loans and such, and are they going to compensate the owner for costs incurred? Likely not, meaning owners will be incentivised to lay civil suit, as generally a person buying them can afford legal representation as well.

100A service is a massive power capability, here by me the standard is 60A, and generally the only time you are going to trip it is if you have 8 individual AC units running flat out in summer, which is not that common in a residential setting. Business, running out of a converted house, will get there, but the easy solution is to go first to 80A service (just a change of breaker and meter, as the wiring is rated for 100A anyway, set by the supplier regulations and the supply side fuse), till you have to install the new cable and go for a 3 phase 60A supply, which will run a small industrial unit perfectly fine.
Very rare not to be able to get 3 phase power, you really have to be rural, and far out, as the standard is a 3 wire 11kV or higher distribution cable, as the losses are lower, though many farms went with a single phase, as they have to buy the cable, so plenty went for the cheap option of 11kV SWER supply, as you only need a single cable, and a giant buried ground mat at the transformer, saving a lot on the cable cost. Does mean you also get single phase AC motors up to 22kW, biggest you can run off a 60A supply, as power source for pumps in rural areas, and a lot of farms have a good deal of 11kV wiring, contactors and transformers, owned by the farm, or leased from the electric authority, with a single meter at the connection point to measure power.
But in cities, or close to them, standard is 3 phase power, and houses are fed from a single phase, which is plenty enough for 95% of all houses, unless you have the multi million dollar houses, where you need a 3 phase supply, because your electric bill is sitting north of $20k per month.

Balloons go where the wind takes them, but they are still bound to follow FAA (or local equivalent) rulebook. Thus over populated areas they must stay above 300 feet, and must also have a air band radio to communicate with the local ATC, plus they are also required to have a radar reflector in the canopy as well, to show up on the local ATC, and also to be visible to commercial aircraft. Not required to have a transponder, but again they are not permitted to be in ATC controlled air corridors either, so most of the time the flights take place far from any airport, or on an airport that had been shut down for the event by NOTAM.
The people complaining will likely lose, as in general a balloon has only a rough control of altitude and direction, as they hunt for wind to move them in the desired path, and often this is not easily possible except by either gonig high or low, and landing is not a precise thing. Either this will be settled before court, or there will be a finding against the complainant, unless they can prove deliberate and regular transgression over property, under 300 feet, and only if the balloon was not in the process of landing or taking off.

Automatic enforcement cameras here by me in South Africa have led to people refusing to pay in the large majority, with the taxi drivers absolutely refusing to pay, to the point government had to scrap the system that was tolling a public road paid for by the motorists multiple times over the years by fuel levies, but where there is a link between the tenders to make it a toll road, and certain people at Lootfully house. However, due to the only ones paying being business vehicles, and rental companies, where they have a contract to force payment, while there is legal precedent that this private company cannot enforce fines by linking them to vehicle registration renewal, unlike the actual traffic police, where not paying this means your renewal will have the fines amount added on as an extra line, forcing you to pay, or face the small possibility that a traffic officer will see the lapsed registration and call for a tow.

@surelyijest Thing is efficiency is hard to measure, you need precise calibrated equipment, which is expensive, while life measurement simply needs a 24 hour timer, set to give 4 15 minute shut offs a day, and a simple visual count of the number of lit lamps. Does take longer, but also is a lot more accurate, as you do not have to calibrate to get the relationship, which is not linear. The 5H45m on and 15 min off emulates a daily cycle, allowing the bulb to cool down so it has start cycles on it added in, as otherwise an always on lamp does last well over 1000 hours in use, as the only stress is slow filament evaporation.

@AC-yj8cx Yes as far as military helicopters go they are small. Plenty of bigger ones, that can lift more, but the Blackhawk is small to make it able to survive.
Takes a special kind of stupid to claim that his driving impaired, on a narrow track, at night, at very high speed inappropriate for the conditions, and knowingly driving with a vision impairment, on a vehicle known for poor lighting. Then claiming the accident was the part of the other stationary party.
Would he have received that payout if he had, under the same conditions, hit a moose, deer, bear, tree, fallen branch, or large rock? I highly suspect not, he would at most have been found 100% to blame, and possibly have had his insurance pay out part of the claim, if they did not entirely refuse the claim because of the driving while knowingly impaired action.
I worked on helicopters both sides of size from the Blackhawk (and met some of those designers of the original optics it uses) and there is no way they can be called small and invisible, unless they are at least 10 000 feet up in the sky.

@mpmansell Special ops pilots only do that when needed, in practise they use a painted point on the ground in open space, and a few observers with video cameras to get all angles. Landing on the field at late afternoon they would not have been anywhere near trees, because of the whole long walk thing if it goes pear shaped, and would aim for geometric centre of the field, aligned on the long axis. Then, likely because it is going to be night, and the possibility of a non predicted storm or high wind, they both applied rotor brake, and also used a big hammer and a few stakes to tie the aircraft down in case of wind. Common thing to do in unprepared areas with no hanger.
Special ops pilots are a particular breed of crazy, but they also have a really strong case of BOPAH syndrome, because of that.

Will those police arrest you because you went out to your mail box to see if there was mail? After all, you typically do not carry ID in your own yard, and might not even have any keys on you either, because the door is unlocked, and you are in comfortable clothing.
Yes time to add the calling neighbour to the suit, because no matter what the outcome, those officers are not paying for it, the entire city is paying for it. Strip their immunity, and sue them personally, and also review all other arrests, fines and such they have, to see if there is a particular bias in their methods.

Actually helicopter blades do not use duck tape, you have a 3M made clear heavy urethane based tape, that is applied to the leading edge of the blades, to keep damage from rain and dust down. Available in a few widths, and sold as plain "Blade tape" to the helicopter users. You apply it to a clean blade, then leave to cure for an hour or three, then fly it. You can be back the next day applying it again, if you fly through a rain storm, which trashes the outer section, so it is normally applied in 1m sections, so that you only have to clean and replace the outside 2m or so of tape, generally around 5 times, before doing all of the tape. Leave it on for a long time, around a year, and it crazes and starts to flake off, and yellows. Takes care to apply correctly, so it does not have edges lift and peel it off.
The cotton duck tape was mostly used for packaging, to seal up hermetic bags that had been opened, before the contents went back to the stores to be properly packed again in sealed plastic pouches, with a dessicant pack inside it to handle moisture, as it could be sitting on the shelf for decades before being used again.

Simulation is possible, look at history, and how the complexity of the universe has expanded as the tools to examine it got better, showing ever evolving layers under the illusion. Just remember that even thought is a simulation, your brain generates this apparent smooth flowing reality out of hundreds of separate very noisy and very jittery inputs, integrating them into an apparent illusion of a smooth seemless reality.
Even with the Dave PDP simulation the base is not really running on the hardware, there is still another layer of virtualisation between the x86 opcodes that are the program, and the actual microcode that takes those instructions, breaks them down into smaller steps, and assigns them to various hardware to do the instruction, then integrates the results back into a result that the next opcode can understand as output of the last one. That microcode is the actual code, all above it is simulation.

Probably supplied by the same company, just had a little more care taken in processing to keep thickness variation, always there with thin foils, to a minimum, and to have a single pass pressing, so both sides are shiny, unlike the regular foil in which 2 foils are done at a time, with a thin oil coat between to prevent sticking, so as to cut time and cost. the foil from the roller is rolled onto a wide long roll, then goes to a slitter, where it gets cut to a width, then the length of foil required per pack is rolled onto the disposable mandrel in the box.

@shimoncohen95 Guy bought a brand new Carrera 4S, and had it totalled, with under 1000km on the clock, in less than a week. Bent like a banana, after being hit on the driver door, and sent 50m down the cross street. He walked away uninjured, and that door was still capable of closing and latching. But written off, more for the chassis being bent badly around the core, and the 14 airbags having gone off to protect him. Would guess he immediately went back and got another one the next day, or at least ordered one. The Fiat Uno that hit him was crushed all the way back to the firewall, engine and gearbox did the impact absorption and folded under the vehicle.

Funny enough we call the one neighbour's car the Valdez as well, though that one is called the Laurel Valdez, as he generally fills it up with kerosene, not the diesel the manufacturer designed the vehicle for. Thus it leaks a little, oil, water, kerosene, and possibly brake fluid and transmission fluid as well, though hard to see against the big pool of oil and kerosene it deposits where it parks, leaving a visible pool on the floor. Laurel as that is a trade brand of one of the suppliers of illuminating kerosene, which is a little cheaper than diesel. Of course he has to let the car warm up, at a minimum of 15 minutes, and it apparently also has to idle when he washes it, to prevent the water getting into the engine.
Only good thing is it will probably never rust, though the alternator is having a hard life, swimming in fluids is not exactly good for it, as proved by it needing to be jump started recently, a few times, and a dragging starter as well, for the same reason.
As to doing it twice, that was me Monday, changing the timing belt on my car. Did it so well i did it twice, because after the first 20 minute struggle with the tensioner, no way to set it other than brute force, we were one tooth out, so, with the experience from the first time, it was done again, and this time the marks all aligned after the belt was on, and still so after 4 times around the combustion cycle to get the marks we put on the belt again to line up. Belt changed at only half of it's life, because a mystery screw, that must have been rattling up top for the last 30 000km, finally made it's way into the cambelt housing, and landed up carving a horrid notch in the belt when it landed up at the bottom. Plus replaced original serpentine belt and the very noisy idler it had on there, as they came off, so new was cheaper to put back on.

Saw a property that has a pipeline easement on it, for a fuel pipeline that runs through the area, and it is also shared with a water pipeline as well. No issues, just that you will know if either one bursts, either your house lands up in the creek, or it blows up. Next door has a bigger issue, they built a garage over the pipe, and when the company comes through to replace it he will have to demolish it, as the pipeline easement states no permanent structures, only poured slabs or carports allowed, plus brick or tar paving, which they will replace.

Mahindra makes a few pickup up trucks, which are not in the US market, because they do not pass US standards, though they do have a good number with Euro NCAP ratings. In the USA they would be considered underpowered, with only a 2.2l engine in it, based sort of on Toyota and Nissan engines.
Opel in the USA is sold under the Chevrolet name, which is basically all the smaller Chevy cars on the road, as pretty much all of them are manufactured by Daewoo, who based a lot of their designs on the German Opel models. Seat and Skoda are all part of the VAG group, but are pretty much all now using parts made by VW, though your VW will also say on trim and such the branding VW/Seat/Skoda on a lot of the trim, as they reuse the parts in different model types over time.

I live where a heat pump is almost useless, in that there are only 3 or 4 days a year where it would actually be useful to have, though the AC is useful most of the year round. however adding in the reversing valves and the extra wire is almost zero cost to the manufacturers, though for cold climes I would say better to optimise the unit for heating rather than cooling, which the most common ones do not do, so the cooling takes slightly less power than heating.
Best thing though for any heat pump is correct installation, not right against a wall, free space around it, and more than the minimum the manufacturer says. Seen way too many stuck right up next to a wall, with no clearance other than the feet, so the coils barely flow any air at all, and plenty stuck right on the ground, with plants growing all around them. No air flow, no heat pumping either way, and lots of money being wasted in power, plus poor performance.

@motleydude73 They also say that things like plugs, and non motor oil, is a lifetime thing. Yet plenty of automatic transmissions and CVT fail just outside warranty. The manufacturers have tested, and found, that lifetime, and also the minimum level of service required to reach it without failure. Yes there are outliers, like the car that is driven long distance, dry climate, all the time, which reaches a million miles, but the same one next off the line, nominally identical, is driven short distances, wet climate, and the engine and trans die about the same time as the body does, with the same service intervals.

Thieves will simply write down a VIN from some random car they pass to bring with. Scrap yards will simply write it in, and carry on as usual. Cheque will only mean they will go to the "we cash cheques" place, with some other fake ID, and cash them for a cut, nothing more. Same for jail time, some will look on this as a step up from being homeless, one year free meals and board. No easy way to stop this other than the jail time, because at least then they will be not stealing the converters for a period, and you can have a special section of jail for them, where as punishment they are either stripping scrap metals for separate streams, for cents per hour, to pay back for the thefts, or doing some other manual labour.

Yes, but requires added software support for it, and then becomes very bound to the particular machine type, as there are so many ways to do a bank switch, minimum being bank size, and location you swap out. The bare Z80 being limited to 64K, along with the IO space limits, was the issue till enhanced Z80 processors came out that were supersets of this.
Still, IIRC being made by Sharp and Casio, and most common in cash registers as the majority of the processing power in the machine, though there they also integrate a whole raft of peripheral devices as well, along with assorted display driver solutions and printer drivers on the same chip.

By me trailer bearings are very easy to do, you go to the parts store, and ask them for a golf 1 rear wheel bearing set, 2 bearings inner and outer, a lip seal, a nut, either nyloc, castellated or plain with the matching pressed steel locking collar, and a split pin, plus a new cap. Plus a bag of grease to fill them up, and you spend 15 minutes per side removing the old hub, knocking the bearings and seal out, then filling the new bearings and putting them in, along with the seal, and placing back in position. Light duty only, unbraked trailers for the most part, unless you get one with an actual brake, in which case you will be buying a set of VW golf 1 linings and drum as well, as that also is a standard thing. comes from the biggest and oldest manufacturer being Venter trailers, who started building them about the time VW introduced the golf into the country, and they used the stub axles from them, as it is a cheap and common part, so easy to get, and they used the whole thing for braked, and a simple inner socket for unbraked, to make a trailer suitable for up to 1000kg, and which was very easy to get certified, as they used parts with a certification already, making it easy. The cups never fit, so often the old ones go right back on, unless you are going to shrink them slightly to make them fit, or use brute force like there.

@Stego27 Yes, though most commercial ones will have power factor correction, so the initial current will be a large single cycle pulse to charge all the PFC capacitors, then the lights will turn on in under a half second. Incandescent lights have a much worse surge, I built a soft starter for a light box, that used 40 40W golf ball lamps, because the switch on surge was large enough to trip the breaker it was on. Soft starter made the surge low enough that it would not trip, and they came to full brightness over 2 seconds. easy to compensate with exposure time anyway, as you had a latitude of 5 seconds for the photographic plate exposure, and more variability due to temperature. Original artwork was done with Letraset and large format photo negatives, and then later on a Apple Mac and a Imagewriter dot matrix printer onto transparency, followed by a Laserwriter when they came out, doing laser tranparencies.

Isuzu, back in business as a brand now by me, seeing as GM decided to shrink back to being a US only company, and sold off everything they had just about worldwide. Who knows, you might see Holden come back as being a US brand again, Though GM seems to be in the game of shooting themselves in the foot time and again.
And yes I currently drive a GM product, even if all of my spares come marked Daewoo corp Korea. Did get a scan tool though, you need it with modern cars, so got a used Ancel one, a step up from the generic OBD reader, and the bluetooth OBD dongle as well. OK not covering all models in market, have met a few already that it does not cover, and with no real ability to borrow a Maybach or a Bentley either, unable to test that it works on those, but it does speak GM, Kia, Hyundai, Honda and VW, along with Mercedes, so has come in useful there. too bad it does not speak Proton other than via OBD, but that at least allowed us to repair the AMT pump, as it identifies as a Renault Clio II, though it does not speak French well, being from Malaysia.

Security theater, they choose a random person, and the machine is flashing lights, but does not actually work, the thing is more there to make people act different. Remember the one airline that does not have any TSA, or any of the security theater, is El Al, they learnt long ago that it is useless, so instead have actual trained staff, not Barney Fife's cousin, to both screen passengers and inspect luggage. they know that they are a target, and want to make sure it never occurs again. Been pretty good at it so far, nothing since the 1970's, and those almost all had a bad ending .

Thing is those remote disable devices are often very poorly installed, often done by the cheapest unlicensed people, who are barely capable to plug a light bulb into a socket. They often just get the module, go to the vehicle, and use a screwdriver, pliers and perhasps even electrical tape, though plenty have been known to use painters tape, or even packing tape, or sellotape, to insulate wires. They find the wiring to the ignition switch, then cut one of them, see if it has power, and the vehicle does not start, and use that then to connect the 3 wires for the module, then take the ground wire and run it to any nearby bolt haphazardly, then tape the lot up and hide the module under the dash, where it can get it's cellular connection most of the time.
Installed poorly the modules draw a lot of power, and drain the car battery in under a week. Often the poor installation, and cheap modules, results in them having a rather high failure rate, and also there is no real verification done on the install, the "installer" gets a fixed fee per vehicle, very low, so it is a drive by install as fast as possible, and as many as possible, so it often is that the device is not actually registered to the vehicle correctly, wrong paperwork, or a pack of 6 modules, 6 vehicles, and he dropped the box along the way and mixed up the tags. thus you can get them being installed so they cut not only starter, but also ECU, or the wrong one is triggered, and the wrong lender gets cut off.
You can get better ones, and have them installed correctly, often drawing power from the OBD socket, replacing the socket with a new one, and hiding the original up in the loom, but those cost more, and predatory loan places will not spend money on better, unless it is for themselves. Also supposed to be removed when the loan is paid off, but the loan places often charge for this, or repo the vehicle, sell it at auction and buy it back, easiest because they keep the keys, remove battery, seats and wheels, and have it go there on a lowbed, getting a fraction of the real value. Then put this all back, put in yet another unit, leaving the original one in (and more wires cut again, because the methead installer will not see his own work) and sell it again, so now 2 units to accidentally be disabled.

Engine rev range is there to use. Yes high revs in drive with brakes on will heat up the trans fluid fast, but most modern ones will very rapidly tell you trans overheat, and limit engine RPM. Driving in my car there are times it will be sitting close to the limiter for a few seconds, then I will change gear, because torque peak is high up, and power peak is somewhere around there, so use them when you need to. Long term not great to run there, most engines are designed to run around half the rev range, but are fine with the occasional spirited drive cycle, here called a free State tune up, because it causes peak pressures in the cylinders, and does a bit of work to clear out carbon build up inside, and on the exhaust side. GDI it does nothing for the inlet side, that you still have to clean.

Was doing that this weekend, not to replace the struts, but to replace the top mount, as the one was noisy, so both spent a few minutes out of the car, and the compressors were used for the 30 second swap action required. New ones mean the springs are now at the right height, as the old ones had collapsed about 30mm on each side. no more noises now, along with the cleaning of the carburettor and adjusting mixture as well. This weekend the water pump and thermostat are going for a change, standard VW Golf service part, easier to do the lot than the parts, 4 bolts as opposed to 15.

Especially extended warranty on things like household goods and electronics. Here there is a statutory one year warranty on all new goods, and thus the warranty company knows that, in year one, where most factory defects will show up, they will use the factory claim process, and not actually have to cover anything. Then for say the common 2 year extended warranty they know there will be little claims, all of them invariably from the owner doing something wrong, or from the manufacturer doing a recall, and thus again no payout, or only part payout. Basically the extended warranty is almost useless, because it either will not cover all parts, or will not cover labour, or will have hoops that are near impossible to jump through to get it right.
Knew a salesperson at one of these places, and half of his commission came from the selling of these, for the above reasons, they were a massive profit for the selling dealers.
Cars the same, sold used with a limited warranty, and if there is a balance of factory that will do for a lot, so the extended warranty is there as a way to make profit, because the dealership gets the sales commission up front, after the new owner has paid 3 months of premiums, and then the owner is paying off this warranty at whatever interest rate for the full period. So whatever was down on paper as the amount of the extended warranty the buyer now pays at least double that over the life of the loan, and every month as well pays a "facilitation fee" of some sort, again a profit, for the extended warranty, plus a charge for taking the payments.
If you have to loan to buy, but not the highest you can afford, and buy cheaper, and for as short a period as you can, and with as big a deposit as you can. That makes it easier to finish the loan, and have the car serviced, and keep it for as long as possible. Having a car loan for 7 years, on a vehicle already 5 years old, in say the rust belt, where the chances of the entire bottom rusting out before that 7 years are up, is very high.

Well, Fiat is known for great mechanical design, impeccable precision in the components, and assembly by whoever was walking past the factory that morning who could not run fast. Also repair does always involve a lot of talking, shouting, and expletives in Italian, along with a lot of hand waving, and the obligatory garlic bread, a few bottles of Vino, and an afternoon siesta as well.
Best thing is the brakes are good, as Italian roads are rather well known for the designers being, unlike their Roman ancestors, completely against anything like straight lines.

@edherdman9973 Well, 2 years of aircraft parked showed up in a lot of failures of systems, when they wanted to restart the airline in operation. Many are still parked, awaiting parts that are now backlogged due to the manufacturers and repair facilities also having to so a lot of catch up, so the idea of parking half the fleet as spares is going to fail in around a year, simply as annual service items, like filters, expire, and need replacing.
You can go a long way in making hanger queens, but you do need a steady supply of service parts to operate the aircraft, and filters are the one thing they do need, and on a regular basis, same with tyres, where they wear out in irregular schedules, and only need a single poor landing, to convert them from serviceable to garden ornaments. Yes you can run a lot of the parts well beyond the advertised life, but failure is not a matter of coast to the side of the road and call for a tow, and in Russia the airports, in general, are far and few, spread out wide, so a failure in flight will be fatal, and little chance of surviving.

@st-ex8506 Yes I know, hanger queens are notorious for this, at one time we did not even bother putting the robbed equipment back into the aircraft, simply leaving it, in the transport cases, stored in the shelf next to it, because it was very likely the part would be robbed again, before it was likely to have the airframe back in service. When you have 5 air data units sitting next to the aircraft, which has space for 2, you know it is a hanger queen. Especially when the main hydraulic block, which is 2m tall, comes out as a complete unit, frame, wiring looms, hydraulic lines and all, to service another airframe, that had a faulty one, while their one went off for the 6 month time service, due to the lead on parts.
It flew a year later, but not likely with the block in, just with 3 bypass rods installed, as the airframes were doing a swansong, and they needed all flying, in some sort of condition. It just had to take off, and fly straight past, which you can just about do with manual strength, the power assist is there for autopilot and heavy lift, which these were well capable of. Will bet most of them had a long list of defects, that were signed off for this.

Would suggest the citizens there each put in daily requests for permits for events for the next year. Said event is that, in 30 days, said citizen will be walking past, or driving past, the following list of public buildings, and needs a permit. That this is the route they take to either shop, or to and from work, not really under scrutiny, but that going past these buildings is defined in the regulation as an event, they need to have permission for the next year to do so, so are entering 365 requests for permit for this. After all, as the regulation is so vague, they might be arrested for being there if their presence would temporarily obstruct the entry or exit from the building, possibly by them obeying traffic regulations, or by them being physically present at said entrance or exit. Thus the need for a permit for said presence.

@cdreid9999 There is a record on all those, they have a conviction, and thus a record. You do not need that a person was a suspect in an investigation, but was never charged for it. That is simply part of doing an investigation, like if the police were looking for a serial killer, and asked the mobile phone carriers all the phones that were in that area that time. You were there, with your phone, in the area, and thus are a suspect, till they removed you from the list by using deduction that you were in a different place, but your phone record is still there. Would you like to have that on your record? That you were not arrested, but potentially, if you were in the place at the time, they might have questioned you, would you like that as well on your record?

A lot of paint testing is done in a test booth, where samples, along with a bare control sheet, are subjected otbake and freeze cycles in a salt spray, with UV light exposure, to see which methods work best. Then you can also do what some do, and leave test strips on the Skeleton Coast for a year, where they get savaged by exposure to full sun during the day, and salt mist and freezing temperatures at night, along with the wind bringing is salt and sand to hit them. A coast where thick steel ship hulls and massive castings, of ships that have run aground in storms, are reduced to near nothing after a decade or two.

Also used to use a shipper, part of the national railways. They would collect at 4PM, and by 5PM there would be an email, about how the goods had been lost, in the trip between truck and warehouse. No problem, they would pay out immediately the insured value, plus refund you the entire waybill (even if only one of the boxes going to multiple destinations on that waybill went missing), plus give a free waybill. So next day pick the order again, and send it again. Generally 2 out of 3 would be stolen, but since we were declaring retail value, not the actual cost, and the waybill was essentially free, the method worked, because the rest of the system, delivering to anywhere close to a rail siding, cheaper than any other courier, with a delivery time max of 2 weeks (but typically 7 days for outlying tiny areas, which no other courier would do for anything close to the price), it was actually a case that often you would get the monthly statement with a cheque attached, as we were in credit with them. No wonder they went bankrupt after around a year, but by then other couriers were around, not as efficient, but also similar in price, and less likely to lose the goods.

@ThereIsNoOtherHandleLikeMine Differs from country to country. By me the vehicle is the insured item, not the driver, so you will need to either take cover when renting a vehicle, or accept the standard limited liability insurance the rental place has. The excess payable differs if it is the nominated driver, another driver over 25, or one who has had a license under 3 years, or not the regular driver.
My last vehicle I bought I got coverage over the phone, just by calling and adding it on, giving the registration number, make and model, and then had coverage, though had to take it to an inspection center within 7 days, for them to verify all particulars, and enter it into the insurance. Registered around 3 months later on, but it was mine, as I was waiting for the finance company before to replace the title, and remove themselves off it. Then went in with the paperwork, COR and the money, and all the forms, and got a new title in my name.

I solved that one years ago, I cancelled the landline...... The phone other than spam calls was almost unused. The robocalls are easy for the phone companies to filter out, as any that come from an account that has every phone number presented being different is a robocall, and the phone provider will know who the originator is, for billing purposes, so easy to find them. Simplest would be to block VOIP exit from all other than the vetted ones, and simply block those that abuse this.
Yes the call is over IP, but to work you have to know who the originator is, and easiest is to block connections for VOIP coming from any public VPN service, and this will remove around 90% of the calls, and the rest you just maintain blocklists of providers who do a poor job of verifying the customers they have.

Large lights coming on after a while is because they are high pressure sodium lights, and those typically, unless you use expensive fast relight ballasts, or use expensive dual arc tube lamps, will take 3 to 5 minutes to cool down before the most common ballast ignitors will be able to relight them. Mast light likely a 1000W lamp, and the side ones are 400W lamps, which do take faster to relight than the big one.
Shipping uses them because they are above all cheap, have a lot of light output, and are very rugged, with them being quite happy running on 50Hz and 60Hz mains with no problem, and also surviving all sorts of mains voltage surges and spikes with no problem, unlike LED lights, which will fail rapidly. Plus will still operate even when exposed, and wet, unlike the delicate electronics.
15000 hour life, which can easily be exceeded with good quality lamps, and they are easy to change out, unscrew the E40 lamp from the socket, screw in the new one, and close the cover. A big advantage on a ship, where you have to do this after climbing a ladder to get to the lamp, only needing to carry a lamp, and a pair of pliers to release the clips, or a screwdriver to undo screws, as opposed to a LED where you need to winch the entire fixture up there to replace a faulty one. Plus they just cycle when old, on for 5 minutes, then off, till eventually they are just a dull blue red from age, or the arc tube shatters inside the glass envelope.

@keithmoore5306 You use simple O ring and packing glands that are lubricated, so that the pressure the lubricated gland applies to the shaft is higher than the water pressure. Yes a much higher loss through the gland, but the alternative is to allow a small amount of water out to provide a boundary film, and use a scavenging pump in the bilge to pump it out at higher than ambient pressure.
Alternatives are to use, for the rudder and vanes, hydraulic pressure, using high pressure hydraulic fluid pumped out through pass through fittings, that then drive an actuator that drives the rudder. That then just means your hydraulic cylinders need a simple boot on each end, so that you keep constant volume, filled with an inert fluid like hydraulic oil, so the actual shaft is protected from sea water. That fluid runs at a much higher pressure in the cylinder than the sea water at any depth it is rated for and they use a simple static pressure measurement to adjust the pump to keep the pressure high enough to operate, but not to blow the seals.
Otherwise for hydraulics you simply make the working fluid water, derived from the internal fresh water supply, and use corrosion resistant material, but in all cases you need to compensate for the ambient pressure.

@halucinator1 15 years and counting by me, they built over the boundary line by 1m, into a nature reserve. Unable to transfer, unable to sell, unable to bond, till the court case is complete, and they then get to pay for the costs as well, along with likely having to remove the offending wall, and cut the structures back to comply with the zoning as well, plus pay for the land use, and then pay the back rates.

Pulley diameter not really going to do much, slightly lower RPM on the compressor, so slightly lower flow, so slightly lower cooling efficiency in traffic at idle. Belt tensioner will easily take up the extra throw with no problem.
AFAIK the variable displacement system is a bolt on, that simply bleeds back from the hot high pressure back to the input, so as to allow modulation of the flow from the compressor to allow control, so it will, with no power applied, default to full flow of the system, so putting it in and not connecting will do nothing. The lower RPM will also help, so full flow will be at higher RPM slightly, probably just off idle, and the system will then simply act as a regular unit. Variable displacement works with electronic expansion valve, allowing control of evaporator pressure so as to allow simpler orifice plate expansion, and strict control over high side pressure using a pressure transducer in the high side, so you need less power to run AC at full power when off idle, improving fuel economy.

@bobbg9041 Not in the USA but by me there are only a few companies that recycle batteries. They take them, split out the acid for cleaning and reuse, and the same for the lead and the plastic of the case. The paste from the cells also gets reground. Then they make new cases from a blend of old reground PVC case and new, which are black. White cases are all new plastic. The lead is melted down, mixed with new, and cast into the plates and terminals, and then pasted and placed into new separators, then assembled into cells. Acid is filled, a mix of old filtered acid and new, which by me is a product from recycling mine dump waste.
Some batteries are imported, but a lot of car manufacturers buy locally made, and they also specify the quality they want, so yes they are different, even if supplied by the same manufacturer, and they are sold aftermarket as well, though at a much higher price than what the OEM price is to a vehicle manufacturer.

Just a tip, get a rivnut kit, and the insert tooling, it will save you a lot of headaches on those panels to bolt things in there. You can also look for some self locking plates at McMaster Carr and get a few of them in, and use them for things that will need a bolt that has to be undone regularly. Buy a few tubes of copper safe silicone as well, to use to fill connector holes that are unused, and to seal where the rear light assemblies go into the frame, so as to keep water out of them. The copper safe silicone is also sold as acetoxy free no odour silicone, it does not release acetic acid on cure, so is fine for electrical work as it will not rot the copper.
And a correction, current does flow in the surface of a conductor, but you will only start to see that at very high frequencies in AC use, in the most part it flows all the way in the conductor. Stranded wire is used more for being able to form it easily in the field, as solid core wire is rigid, and will hold bends well, and for very high current you need hydraulic tools to bend it. Stranded flexes, and thus the copper inside does not work harden as much, though it will do so eventually, especially at a soldered joint, where it behaves as a solid wire then. Get some tie wrap bases and 3M VHB adhesive strips, and use it to hold the wire loom to the electrical chassis, no flexing with vibration then. A roll of VHB tape will also come in handy when you want to hold panels together without rubbing.

Stress relieved means that, after forming, but before machining the flange on the front to make it flat, and do the drilling and tapping to allow the face to mount, they were taken, placed in an inert atmosphere oven, and heated up to something between 600 to 800F, or 315 to 420C, and left there for a few hours to allow the brass to relieve all the stress from forming, so it is soft, and will not split under impact, just deform. Then final machined, and provided with that protective layer of lacquer to keep it good during storage. That way when you go to drill the holes for the conduits you only have soft metal, and there will be no splitting or hard spots in the brass. In a submarine you really want watertight joint boxes, as this keeps the connections from corroding, and the soft brass allows a good seal as it deforms when the conduit is tightened, making a metal to metal hermetic seal. You can have it under sea water for 10 years, and open it up to a shiny inside still.

Only issue is that you will eventually end up with a recovery machine full of air, and then need to freeze the tank to almost all liquid, then discharge the gas out. Even residential units I often would recover the gas, made a manifold and used old fridge freezer compressors to do the scavenge, which meant I could get 90% of the charge out before changing the compressor. Did put a big drier in the suction and discharge lines, to handle the moisture and stuff that could be in there from the compressor failing, and those would eventually land up with the scrap units.
Supplier hated that I had good enough records to be able to claim compressors under the 5 year warranty, though often I would have had to replace a condenser coil at 3 years, because those turned into confetti and rust, especially on the window wall units. I was about the only customer who bought coils, other than those machines that failed within the 1 year full warranty. Capacitors were pretty much an annual replacement item, you might get 2 years out of them, even the OEM ones, and new compressors always got a new capacitor, and for some of the larger units also a hard start kit as well, especially those that were oversize for the load, and thus ran short cycles.
Bought 3 sets of gauges, original cheap one, then one that did R134A as well as R22, then the last one because I needed R410A capability. Note as well that those hose sets do eventually wear out, and they start to leak through the rubber, and get stiff and brittle. Vacuum pump better to spring for the dual stage units, they get better vacuum, and are almost good enough to make neon signs with, or at least use as a roughing pump for them. Change the oil regularly, all too often see pumps with either chocolate milkshake in the inspection port, or solid black sludge there. Refrigerant mineral oil is good enough, and cheap as well, and a 5l ( around 1.3 US gallons) bottle of it lasted around 20 oil changes.

Nissan electronic module has a small RC oscillator in the chip, and a driver that divides it down from a higher frequency, so the resistor and capacitor values can be reasonable close tolerance parts, then use the shunt resistor (the loop of wire on the board near the relay contact) to detect lamp current when on, and if it is below a threshold it will switch to a higher flash rate to indicate a blown bulb. Current typically is set so the trip point is 2 21W lamps triggers it, but if you have the 2 21W lamps plus the 5w lamp it is high enough that it will not run at fast rate.
Some also have an added threshold, so if you have 4 21W lamps ( hazard operation) on there it will flash at a lower rate, with a much reduced duty cycle, so that a vehicle on the side of the road will have the hazard lights run for a much longer time before the battery is flat. Generally with this you also need to install a trailer relay unit if you want to tow with the vehicle, which removes the trailer lamp load off the circuit, and thus the trailer unit also often will include, if it is the OEM version, another lamp fail circuit that will tell you if trailer lamps are faulty as well.
Modern vehicles have body control modules at the rear, where they drive each individual lamp separately, and also monitor them all the time to check they are not faulty. Thus the indicator and brake lights will also fail safe, in that if a brake light fails, the indicator will come on at constant brightness on the side that has failed, in concert with the other side, though generally almost all vehicles that have body modules for the rear lighting use LED lighting for all lights, except the reverse light, which is still an incandescent lamp, as it will almost never fail, other than from accident damage. Still have lamp failure detection in them for the LED units, though that often requires using a dealer diagnostic tool to get the information, as that only sets a failure indication when all LED units in the signal fail.

I think they forgot the second unit off there. Instead of 500Watts that they were bragging about, they forgot to use the second word in the actual unit, it is a 500 watt second battery, or, more prosaically in the more normal SI nomenaclature that people are more familiar with, it has 500 joules of stored energy in it. Not 500 watt hours, which would actually make it a really compact and high capacity power source, with 1.8 MJ of stored energy, far more than your similar size lithium pouch cell pack of the same volume, but instead it will store roughly the same energy in the "easy to replace charge collection plates" ( bet nobody saw that small print and thought why the charge collection plates wear out, but not the sea water) as a single standard duty ( hardest thing to find these days, even the cheapest Chinese one is marketed as heavy duty) IEC standard ( yes there is a standard for a zinc carbon cell, basically to get the ability to market it with a size in the IEC nomenclature, you have to meet the dimensions, and capacity has to be greater than the minimum in the spec) zinc carbon internally depolarised AAA cell. I think the AAA cell is a lot cheaper as well, and easier to recycle, as it only has zinc, carbon, a drop of tar, some wood pulp soaked in manganese dioxide and ammonia, and a bit of plastic as sleeve and top cap.

I only ever bought one vacuum cleaner, and that was a small cylinder Aim branded one. The rest i got for free, generally Columbus, and they last, just need to buy spare parts to fix them occasionally, and new bags every so often. you want good buy Columbus, or Kärcher, or WAP, which all are commercial machines, and they are the ones you see in the rental market, and those machines go through hell in there, but survive. The commercial machines Ridgid sells are not made by them, but are made for them, and they need a good product, so keep the quality up. The others sell badge jobs, made by some cheap OEM, who gets the mantra with every order of "MAKE IT 10c cheaper or we will change supplier", so they rapidly go from barely acceptable, to total junk, in a few months.
Of course they will make hoops for warranty, because a warranty claim costs them not only the cost of a unit (doubt the OEM got more than $20 for the unit in the first place though), but also shipping for $30 to send it. Lost the whole $50 profit they made on it. Rather make the customer give up and buy another, so they get another sale, remember the brand names are often held by the same large holding company, so a sale is a sale, and the brand is indifferent, they often have the exact same call centre handling returns, and only the phone number used flashes on screen how to respond with a brand, the rest is the same Byzantine system.

The light item is also interesting in that, by law, by me all vehicles have to have some sort of retroreflective parts at the rear, normally integrated into the light cluster, to indicate there is a vehicle there. Trucks and trailers, plus commercial vehicles, have a lot more regulation regarding this, in they need to have side, front and rear contour marking on them as well, so that, irrespective of the angle of the vehicle, it is visible at night from a distance, even if it has no lights lit, or is making a turn. There are specifications as well for the tapes used, as to width, minimum length of gaps, and that each section is to bear an official type approval stamp, so the tape comes with a embossed marker every 10cm on it.

@SeanLavery Yes hardware faults, and no way to fix at all short of redesigning the chips themselves, which is why you have different step levels, each one fixing some of the hardware bugs, and sometimes with the only fix being "do not use this function", and the microcode being updated to disable it entirely. most relate to how speculation works, as the processor will use spare clock cycles at the fastest speed to guess the result of any branch, flag check or arithmetic function, based on past results, and start to execute the next instructions, so that if the result is right, it already has done the work. Thus you can detect wrong results from the time it takes to do this, as a wrong result means the whole cache now has to roll back the core to the now proved correct result, and dump all the execution that took place, and this time is easy to monitor from context switches, so you can know fairly confidently the result of any branch or flag.
The same for RAM, cells adjacent bleed charge to each other, and you can use this to reliably flip a particular bit by thrashing the bits around it to flip it, allowing you to change your program priority and owner, so allowing it to read memory it should be segfaulted out of. Or use the hammering to flip your memory bit, to reflect the values of the adjacent cell, to get that info out.

At 90% plus copper, with the rest being nickel, they probably would have gotten more for the coins as scrap copper, though they would have had to have a pretty decent furnace to melt them down to cast into bars, and likely would have had to add in zinc (from pennies) and aluminium to make a brass alloy, so as to hide the silvery lustre, which is not possible with pure copper. 6 tons of brass would make them around $25k, with no real risk of being caught, as the metal has been diluted down away from coin metal.
The other items stolen would be fenced off fast, frozen shrimp to a few delis, and to a few restaurants, easy when they buy a box or thirty for a quarter of the price. Same for booze and cigarettes, sell off at a discount, and a lot of the smaller sellers will take a big buy, and simply sell them to cash customers, taking the money as tax free and off the books.

Finish also runs very regular bulk specials on the packs, and as well the pack size is variable, so that you can get a pack with 21, 30, 36, 48 all on the same shelf, all of them almost identical in size, but with only the one pack size discounted, so you often pick up the bigger, more expensive per unit, accidentally.

Will add that a sneaky way car shysters by me hide a rebuild title from casual view, is to move the car registration districts a few times. As the title paper only shows the last 5 registration authorities they often will buy it off auction, then register it at another adjacent province, then move every month to a new one, in the interim actually fixing it to the point it will run. The moves are just on paper, the vehicle gets a roadworthy test, then, in the validity period of this bought one, vehicle not needed (6 months validity) for test, it gets "moved to 5 different registration authorities, each one giving a pro rata reduction in fee for the previous one, as the vehicle is "sold" to different dealers for a low price, or on consignment, or as a swap. After 5 moves, the original registration, easy to search for and get accident info, along with auction info, rolls off, and they then finally fix the vehicle, or at least get it running well enough, and then get another current roadworthy that it might actually pass (sort of, if Stevie Wonder was doing it, and had Beethoven there to hear the noises) before selling it to some schmuck.

@chiedzawith2ds Only because they could borrow money cheap, but now the interest payments are becoming equal to the GDP, and when you have to borrow money to pay government salaries you are only kicking the can down the road a little. Yes you can ask for a house, but the chances of ever getting to the top of that list are about the same as winning the lottery, those houses are built, then sold off to connected people, and then rented out, the money all being cash, with zero tax paid. Same for the transport industry, the owners and controllers of taxi groups live in massive mansions, yet on paper they earn nothing, and pay little tax. The corrupt take the money to build houses and such, start the work, get part way, then the money is gone, and so is the builder, starting up another few dozen companies, paying bribes to government officials to get tenders, and then simply doing part work, then closing down again and rinse and repeat. So many government workers in high positions sitting at home on full pay, because of pending cases, and if the case eventually makes it to court they simply resign, and the case simply gets dropped, and they apply to another state institution, where they do the same again. 5 years to even get a court date is not unusual, and the case might be heard in 10 years.

Had the cloned plates before, just took an hour, downloaded and filled out the form on the relevant authority website, printed it, took it to the local cop shop to get it certified and stamped, and scanned it, emailed it, and posted it. Never heard back either, but as next year registration was not flagged, it was cleared. There are enough cloned plates that they have a department that deals with them. Oh yes, this was for etolls, which are overwhelmingly unpaid, as the argument is that the taxpayer already paid multiple times for these 2 main arteries, and paid for the upgrades and maintenance, so why should they pay a private company again to travel on these public roads, that the company never built, never maintained or upgraded, but did put the toll gantries up on. now the suggestion is to repurpose them for ANPR and ASOD purposes, which is rather ironic, in that the average speed there is half the posted limit at almost all times.

Automatic bleed is also a good thing when doing a brake fluid change, as you get all the old fluid out of the ABS module as well, and bring in fresh fluid. You probably could change the fluid again after doing this, to make sure as much of the old i out, but simply emptying the reservoir and filling with new fluid will get most out, as it all gets returned there, so a change there, followed by the second round, will get good results. Also you will need to do 2 full fluid changes, with the ABS bleed, if going from any under DOT5 fluid to DOT 5, or vice versa, to make sure you get the incompatible fluids completely changed out.

Here by me the law got changed, so that an auction has a reserve, determined by at least 3 local estate agents, and the reserve price is set at 80% of that average value, and thus the sale is deemed fail. Now, this case can easily be seen to be non legal, as they will need to prove that the owner was served paperwork, was told of the auction, and that the auction was legally announced as to time, place and what was on offer, and the auction had good standing. Case here can be made against the auctioneer, for short selling deliberately, and let him prove it, as his entire reputation is what allows him to be one, and being suspected of doing fraudulent sales is a sure fire way to get his registration pulled, and for the entire auction community, both buyers and sellers, to consider touching him to be a very bad reputational risk.

Will add that a lot of appliances these days draw power all the time. they have soft power switches. You want a switch when you have actually sensible mains voltages, you know, where you do not need power cables thicker than your thumb to power a toaster, or have an electric iron that has useful power, or have an electric kettle that will actually boil water before the heat death of the universe.
Switch allows you to disconnect even in operation, and not draw massive arcs from the contacts in the plug separating. Wimpy 115VAC and massive current not too much of an arc, 230VAC and the same current much better arc, and of course the rest of the planet sleeved even blade pins. Even the Australian socket outlet is sleeved, and it is very much based on the US socket, and just angled to make it different. Even there in addition to the sleeving the plug base is larger. US plugs just are stuck with being from the 1800's, made by a guy who wanted to make them cheap and simple, and made them fast, so of course flat strip was the thing, easy to cut.

By me similar thing, except those mine dumps were actually mined again for the left over metals, and the fine powder was pumped down the old mine shafts to fill them up, gaining a bonus of removing the dump, and reducing the sinkhole risk, plus also getting a byproduct of gold, platinum, silver, copper, lead and other metals, plus a lot of sulphuric acid recovered for industrial use, and massive amounts of mercury, that was the old method of gold extraction, recovered. Then the land was covered up, and sold as residential property and new suburbs were created.

US breakers are specified slightly differently to EU and rest of the planet. There that rip current, say 10A, is a current it will trip at within a certain time, and normal operation you derate to around 70% for continuous loads. Short peaks for start up are allowed, but long term, over say an hour, will trip them at the face plate current. Unlike the DIN and others, which are rated to not trip at the rated current.
Incidentally a hot breaker will trip at a lower overload, at least till it cools down, and a breaker in a board with adjacent hot running breakers will also trip closer to the minimum of the curve. conversely a breaker outside, in very cold weather, might not trip at all other than on the short circuit current, which is why you often will find the feed to a house is provided by a series connection of a fuse and a breaker, as the fuse, normally at the supplier tap off, will be guaranteed to always fail after a period of moderate overload, while the breaker is possible to have fail shorted.

I had a similar case, lawyer showed a document purported to be signed by the owner, and I asked the lawyer who had "witnessed" the document if he was willing to stand up to a judge and verify that the person had signed the document. He said yes, so I told him that in that case I would go there with at least 100 hand written notes, all signed by the owner, and all with his distinctive writing and signature, and with a managing agent with likely hundreds more filed, as he was not only a slumlord, but also a prolific complainer, and I had at least a decade of written notes from him. Was he still willing to offer that document in court for the eviction proceedings, and the forced sale, and he was funny enough not willing.
Case went through, no defence, default judgement, because the judge asked if they were the owners, no, do they have any documented proof of tenancy, no, so shut up and sit down, and a default judgement plus eviction. Went for the 10 years of no payment of levies, full plus all fees, and the balance went to the lawyer. I then told all those with claims dating back for damage to send in all bills to the lawyers, and made an even bigger dent in that amount. Remainder was eaten by the monthly tracing agent for the owner, and I guess it went all within a year.
New owner went up, and told them that they had 2 choices, but that they would be leaving at 6PM. the choices were either leave via the door, or leave via the windows, and he had 6 armed police with him to "reinforce" the option. They used the door.

Uber by me has been forced to accept the drivers are actually employees, because they get told when to work, and have to follow direction from the app. Not a happy company getting that, especially as the drivers also have a right to strike, and have done so on a few occasions. Also getting into court for drivers assaulting passengers. The drivers also have to pay for insurance through Uber, though I can bet they get shafted over for that as well, one of the reasons they strike, because the drivers know what they get per trip, and what Uber charges.
As to LG, every single LG refrigerator arrives not in cardboard, but in a plastic shrink wrap now, with polystyrene corners, and only cardboard is a sheet on the base. Yes that comes off before delivery, unless the customer collects at the warehouse. Only thing LG supplies in cardboard are AC units, because those are thick wall cardboard, and those units are normally stacked up 10 high. Fridges are 4 high stacks only.

8in drives hit up Curious Marc, he has a collection of working ones, and probably will be happy to get you one that is working, tested and aligned, and you can look out for old ones, and disks, to get tested, and also to have another drive, that will interface with a genuine IBM XT controller card, and a small adaptor card, to allow you to use the PC platform to cross compile software on, using the tools and code you are familiar with.

Landscape truck hitch not connected correctly, and they never bothered to put the safety chains on. So while towing it came loose, and when it hit the median likely a can of gas, very likely loose in the back of the trailer, because they had just filled the plastic can, or had filled the grass cutting equipment, came flying forward, and ruptured on impact with either garden tools, or the front of the vehicle. liquid poured out the side, and was lit by the sparks of the side metal scraping on the concrete barrier. You can see from the smoke and the darkish flame, this was 2 stroke fuel mix, the oil only partly burning as it was dripping out of the bottom and sides of the trailer. If it was like any landscaper, the fuel was in a plastic 25 liter container, probably with no lid, as that had long ago been lost, and the fuel had made the plastic yellow and brittle with time.

Some professors who published the textbooks also told, on the first day, that there was a dozen copies in the library, and also suggested that some students could check them out, and also that you could come to his office and get a copier code, provided you made a few copies of each page, so all could get a copy. Was not his code, but the actual main admin code, so it could never be blocked. Electronic ones you can find now, plus some lecturers also tell you to get a copy from the Indian publisher direct, saving around 95% of the cost of the book, and getting the identical copy directly.
Note that often the only difference between editions is that the page numbering moves slightly, and the self study section at the end of each chapter is the only thing different, same questions, same answers, just the order is different.
The old joke of the psychology professor who used the exact same book for decades, exactly the same material, exactly the same questions, just that the answers were different.

Likely using a bail bond, so they only need to present 10% up front money, with the bondsman providing surety for the remainder. so now have to have an ID to present to the bondsman and the sheriff to get the paperwork right, as to who is responsible for paying on skip. Likely they made the 2 fake ID's at the same time, so they both had either the same info, or the same errors in the manufacture.
Funny thing is by me ID can be any one of either an old ID book, hand written and stamped, or the computerised later version, or the latest card type, or a passport, or a drivers license card. However the drivers license card cannot be used as proof when renewing your drivers, even though it is a photo ID.

Yes, which is why pretty much every toll plaza is going contactless, or using tags. Do not travel on a toll road much use a tap and go, travel a lot get a tag, and load credits on it once a month to cover the fee. USA is the only country where you hand over your card and it is out of sight, but every other country accepts tap as payment, regardless of amount. USA also still has embossed cards, because there probably still are merchants who use the zip zap imprinter and carbon copy paper as well. Here that is long gone, no place has that, as the card terminal can easily store 1000 transactions if offline, and the bank will have a current hot card list uploaded to the terminal every day, and for offline transactions over a limit you will have to call for authorisation anyway.

Outer layer would be destroyed by the sun, but the aluminium under will be mostly fine, except where the plastic of the threads has been destroyed, so the blankets will have sagged and deformed, with likely some of the structure visible now. Paint exposed will be basically only the oxide pigments, and the mineral powders and fillers, nothing organic left, except where sheltered. Glass exposed could likely be a lovely blue from photon and electron bombardment, though most of it would be brown for the same reason. Thin film of dust on everything, as it rains down from the sky, as a result of micrometeorite bombardment nearby causing dust to fly up, and also from static charge causing particles to levitate in the vacuum from charge generation due to impact from solar wind protons and electrons.

Would take me about 3 days to rewire that tractor crane, nothing too complex about the electrical system, and easy to work on as well, just with heavy steel panels. did the same to another tractor that had an electrical fire, and had all charred looms.
As to putting a turbo on, you will kill that engine in a month, unless you turn the boost down to practically zero, they really will last forever if not stressed, but the turbo versions blow up and grenade themselves.
running on Jet A1 I would guess the exhaust is now a nice white inside, not the normal sooty black, and it runs a lot better than when it was on agridiesel.

Driving instructor, with lots of hand waving, in typical italian style "See, this is why we drive carefully in the rain, and also, remember that the Beyershe Mist Wagen always has an idiot behind the wheel, so be careful around them", followed by him getting on the phone, and telling the school they need both a tow truck, and another car to pick them up and take to the hospital, because his hand is injured from all the waving. Plus spilled his coffee.

So basically a tracker unit built into an easily removeable unit, that will be the first thing the car thief rips off and leaves when he takes the vehicle. As a bonus all the owner gets is the ability to change the plate colour without actually having to get a screwdriver out to do so. Tracking systems are generally hidden, and often actually cheaper per month, with much better recovery rates as well. $240 per year idiot tax in reality, or for the total idiots $300, and likely to rise every year, plus of course when the battery expires (bet that is a hard timer, not actually the life of the battery, which is probably closer to 10 years anyway) you now will either have to buy a battery from them for $200, or buy a new one, and toss the old one away.

@PebblesChan There were 5A regulators available from National Semiconductor, in a TO3 package, with a pretty high per unit price, that needed a fair chunk of aluminium to get that 5A out of them, even with the minimum input output difference of 3V, thus the 8V supply rail, that was 8V fully loaded, to 10V unloaded. 15 to 30W to dump on a card was hard, you had to either have a heatsink, running the full length of the card, with fins that took up another card space, or have it take up half the card space and still get a card in next to it. Or have a cooling fan directly cooling just that frame section. S100 bus simply did it the easy way, need 5A, put 5 1A regulators on the top of the card, each with a heatsink to handle 6W, and have 5 Vcc bus rails to the assorted chips, so each rail was only loaded to just under 1A. Easy with TTL and NMOS, as power use really did not change much with clock rate.
Cray did it even simpler, as ECL has a current use that is almost constant, irrespective of clock, so all they did was to have a single ferroresonant power supply that used massive copper busbars to deliver the -5V2 to the cards, with absolutely no regulators at all, just a ferroresonant converter that made a constant AC voltage, and then simply tossed in a massive set of rectifier diodes, and truly massive capacitors to smooth out that supply. Then used liquid cooling, to keep the chips on the card frames from melting themselves off the boards. No regulators, and a variac with autotune to fine tune the voltage.

Take 2 pins of the right diameter, and wind carbon fibre string between then to make a core. Then use more string to wrap around the long length of string, so as to make the long lengths pull together. You will need to leave the long wrap loose, so the wrap can pull them tight together, probably also first making a circle around the bores, so there is an even layer, then wrap the string lengthwise and then pull together in a wrap. Then you can use the mat to make the outside, using that vacuum form to make a wood replica, that has larger dimensions for the split area, and also wind more string around that area as well. No reason the composite should not be as strong as steel, just needs to be aligned correctly, not with a woven mat, as that is merely good as a panel, you need strength only in one direction, for both compression and tension. Thus the long string for tension, and the tight wrap for the compression side.
After all the long length of the rod did not fail, but the attach points did, so you need to beef those up, and using carbon fibre string is the best for that, to allow you to control the direction of force.

@nss5353 By me being a guard in one of those companies is always every day wondering if you will be held up and robbed, and more importantly surviving. They all know that the odds are pretty good that they will be in an armed robbery, as it is very common, because that is a large amount of untraceable cash, and there are lots of people who want it. Now to the point each armoured van has at least 2 separate escorts, in bullet and mine resistant vehicles, that tail them, and not only cvash, but also deliveries of high value goods, like jewellery, phones and computers as well have the same treatment.

@skiboskeeskiblets By me there are no guarantees about insect damage. You can tent it, and it is pest free, but that week one can fly in and start up the damage again. However I did see a house, 100 years old, where there were absolutely no bugs in the wood. Owner would, till he died, having gotten it from his father and grandfather, go into the attic every year and paint all the exposed wood with a mix of creosote, linseed oil and paraffin, so the wood all got a coat. Pest control came to inspect after last family member died (original copperplate hand written deed, complete with original OHMS wax seal with ribbon, and later on stamp duties and addendums on the rear as it was passed down) and said this place was impossible, not a single bug, not a single fly, not a single gecko lived in that roof, doors or frames. Frames just got the linseed oil and paraffin every year, smelled for a week, and were slightly tacky till it polymerised. hose is in what is termed the borer belt, where you can be sure pretty every house has some, treated wood or not, unless you have very old house with green arsenic chromate treated timbers in the roof.

Small correction the oil pumps and cooling water systems will all be run off the 440VAC bus, as they are low power loads, under 20kVA per motor, so easily run off a 440VAC power link, which is a lot cheaper motor wise, as you use standard insulation on the motor, and standard insulation on the wires, which is a lot cheaper than 6600VAC insulation and control gear. Same for hydraulic oil pumps, all running off the low voltage bus. Bow thruster high voltage because they need the power delivery, and the long cables for them also make high voltage advantageous, despite the need for much more robust and thicker insulation, and much more expensive control gear.
The high voltage on a motor means a much larger motor frame, as now you have so much more volume in the windings being occupied by insulation, instead of copper or aluminium wire. As well with high voltage insulation cooling is harder, you need to either have air channels down the windings for cooling, and run the windings at a much lower current so they generate less heat, or have much lower power density in the motor, making it much bigger for the power. Expensive below roughly 50kVA, and the 6600VAC control gear is a lot more expensive over your common low cost 440VAC control gear, that is cheap, and common world wide in industry.

Here by me same for fishing, you lose your car. Solution adopted by many fishers is simply to get somebody to bring them there and leave them, and go home, see you in the morning. For the undersize fish the solution is to take a big cooler box with ice, and a hand mincer, and all the undersize ones go through it, and into a plastic bag, and into the cooler box. Hard to see without DNA testing if the fish was out of season, in season, or undersize, plus all the gutted ones go in on ice as well.

@LRRPFco52 You want an example google Sanele May, who was given a HGV to drive, when he could barely start it, then was expected to drive 6 hours to deliver a load, and collect one coming back, and be back next morning. He wanted to keep the toll fee on the one, so used the bypass, and because he did not know how to descend a hill, used brakes till they faded completely, and then took an off ramp, and wiped out a few dozen people in the ensuing accident.

@rhetorical1488 My mother got her drivers back in 1956, and all it was was a practical test, did you know how to get into and out of the car, start it, use the gears and brakes, and drive along a road and obey signs and the road markings. Then you passed. no parking, just that most driveways in Central Africa at that time had a unguarded concrete slab over a 6 foot deep ditch, and you had to drive over it to get out. 6 foot deep and 8 foot wide, because that just about handled the daily rainfall in the wet season. On roads that more often than not were gravel or dirt.
She never took a written test ever again, and it was accepted when she moved countries as well. Only thing when renewing was an eye test, and that she could pass. Only ever wrote one car off as well, and that was likely the other driver cutting a corner, and hitting her.

Fake plates are easy, plenty of them around, simply because they are so easy to make. Got a few toll bills from that, and the toll people know the number of fake plates is so high that they actually have a separate form you fill in to say this is a fake plate, not a misread or you dispute the camera. Fill in, get it signed by a commissioner of oaths, scan with the ticket, proof of ownership of vehicle, and email, and the ticket vanishes, which is actually faster than the other methods, including actually paying for the tolls if you do not have the transponder.

@Mike-01234 Just takes one election to bring in a bad actor, who will run the HOA into the ground, and destroy the community. mostly because the USA has almost no laws governing them, and fragmented laws in some states only. they need to have a set of common laws covering what they can and cannot do, and a minimum set of laws about what they must do, transparency and making public all records being foremost among them. So many cases of HOA's where the monies just go missing, and no records available until the owners actually get a court order to force the showing.
Best thing for many HOA's is to dissolve it completely, and if there is nothing common, like sewage works, roads and such that actually improves home values, as you now only pay the city, not an added tax that you have no control of which is HOA dues. But HOA is popular for a developer, because they build slow, get to keep the dues during construction as profit, and then the city or town gets a new suburb to tax without actually needing to spend any money to build roads, electric, water, gas, communications and sewage infrastructure, or to maintain it, but gets the tax revenue as if they had. These kind of HOA's should not exist past the building phase, let the city/town take them over, because they get the infrastructure already built, and the HOA is actually now an impediment as it adds a higher cost of ownership to the property, which strongly affects pricing.
It is showing that non HOA properties next to, or in a HOA, typically have a much higher selling price because they are not deed encumbered by a HOA. some times you need a HOA or COA, because of common property, but most cases of separate houses on public roads you really do not need it at all.

The flush is needed because the bean counters wanted the least number of oil changes that would get 99.5% of engines out of warranty without them grenading, as the cost of doing those changes could be a negative factor in TCO during warranty. By me now the warranty is still enforced, even if you do not go the stealership route, so long as the service station is registered with the RMI, and stamps the book, the warranty has to be honoured. Losing stealerships the gravy of doing oil changes, charging the customer for oil, plugs, filter, fuel filter, air filter, pollen filter and a 100 point inspection (then claiming all that extra back from warranty from the OEM), while in reality only doing oil and possibly filter change, then pocketing the extra. Oil change because it is the only thing easy to check, unless you have no dipstick, in which case they might only reset the service light, and clean the car, as you cannot check without removing covers and draining the oil.

When you call the police on their lines, the calls are always recorded, for use against you in court. There are a few series, hosted by William Shatner, about that. No difference in them calling you on the same phone systems, and you recording the call either, because in most PD departments all calls may be recorded for quality and audit purposes, and for use in court. No difference if the recipient records, so long as the PD version also matches, so there has been no quick editing on either side to tamper with the recording.
Sending this down to be thrown out is the important thing, as it shows that public officials, in acting in their official roles, cannot be sheltered from their actions and words, and that they have to be held accountable for them. Either video, or audio, to have a permanent record that they have done an action, and that it was either right or wrong, but a record should be held in all cases.

Buy the cheaper models, which do come with the charger, USB cable, headphones and micro SD slot. What are the Brazilians going to do when the phone does not come with a SIM in the box, or with a year of free calls and data, because without the SIM or a servicce it is not usable as a phone for the greater part, and it does not come with free wireless either. All things you have to pay for separately.
And yes I have a good number of chargers, have been keeping them and giving away as the old ones wear out. You have more waste from the packaging than the chargers, as they also can be used with other phones if you do not buy into the Apple fanboi way, as they are not locked down to a phone, and you do not get compatible units, that otherwise are equal in all respects to the Apple brand, but because you do not pay the Apple tax, making them the richest corporation in the world, they stop working after upgrades, despite being made with the same parts as the originals.

Not true, spread spectrum clocks also jitter the clock to make noise more broad band, to cheat emissions tests that sweep across a band, so the average noise becomes lower, and the clock can jitter by 5% easily. Critical timing functions use separate crystals, though all timing on a CPU and computer is designed with tolerance in mind, as nothing outside the CPU cores is too critical timing wise, so long as edges of data and clocks line up with the correct relation to each other.
The most critical timing is not in PC's, but in cellular use, where your timings even compensate for the distance from the base station to the mobile device, as the shorter the dead time between switching between each mobile handset you have, the more data you can transmit to the particular handset per frame, and thus you get distance compensation, as well as dynamic power control, so that the receive side sees a near constant signal from all handsets at the base station , so it does not have to degrade data rate, and the transmit power to each handset in the antenna field varies wildly, so they get a near constant level as well, The other handsets are muting the receivers while waiting, so they do not get desensitised by high signal levels, and the base station will dynamically allocate the handset position per cycle, to not have high power signals during the potential window time. That needs an accurate clock, and no base station runs off a regular crystal, they have normally heated ovens that keep the crystal temperature stable, and this is in turn fed from a Rubidium or Cesium atomic clock, that in turn is synchronised with a GPS receiver per base station, to get a clock accurate to within a clock cycle across the entire network, and giving free time to each mobile, as they also need an accurate clock, though the base station will compensate for the drift in the phone clock as well, in the telemetry channel each phone receives.

@phlodel If he paid a deposit then they will give it back. If he paid up front, they would have no way to sell the vehicle, as they are acting as delivery only, and if the dealership sold it they would be looking at a very nasty legal case, which would result in them having to not only pay the original customer his money back, but also pay for a brand new vehicle in that trim spec as well for them, as the original vehicle would no longer be able to be titled as new.
My BIL had that, paid full price for a vehicle, delivery around a year out, with his custom trim spec and interior. Year or so later it arrived, but, due to currency fluctuations, it now was triple the price, but he still paid nothing more for it. Insured with the regular insurer he used, and not a week later it was written off in a T bone, with another vehicle driving into the driver door, at high speed, and going wrong way up a one way street.. Few bruises and cuts from glass, and all airbags deployed, and he was fine. Next day insurance was not happy, as the insurance was for replacement value, and that was now 4 times what he had paid originally. Unfortunately he wanted a replacement same time, so the CEO of the local dealer network lost his brand new company car, also on the same shipment, as it was the closest trim spec to the totalled one. Back down to driving the lower spec one.
Scrapyard that got it was unhappy, though the owner took it as part of the contract with insurance, and spent another year ordering all the parts to repair it from all over the world, and then sending in all the electronic modules to get reflashed and working again. He got a nearly new luxury car at the end, for half price, so drove it all the time.

Spam is processed, canned and then, in the can, it is cooked in bulk. Cooked in the can so that all of the bacteria is killed, and it is sterile. There is heat treatment before canning, which is pretty much cooking it in bulk, before it is canned, but the final stage of cooking is done after sealing into the same. Likely that batch was short time in the big steam cooker, either the temperature did not reach the peak it needed, or the time cut off early, and the morning crew did not notice it, until somebody at QA finally read the log for the stem oven, and noted that it was short a few hours of cooking..
Spam was invented, mostly because there was no real way to refrigerate meat, so in Brazil there was a company who developed a method to can meat, cook it in the can, as there was a lot of cattle. Then ship this the 4 months or so it took to reach Europe, and capitalise on the canned meat not needing to either be eaten immediately, it did not involve massive amounts of salt or smoking, and the meat was recognisable as meat, and did not have to be soaked to remove the salt, or have a strong smoke flavour, so it was usable as is. Plus no need to ship cattle across the ocean, needing 4 months of food and water (plus 10 crew just to shovel off the deck into the ocean) taking up half the cargo hold.

Bearing races the inners and outers, so long as they are the same lot number, are interchangeable, and even if slightly worn will work. The reason you do not want to mix them is that they can be different size, as the factory makes the inners and outers, and measures them into different size ranges, and makes up the complete sets from them. so any from the same lot are interchangeable, and will wear the same in use as well. But a different lot will possibly be a different diameter, and thus you will get a small section that takes all the loading, wearing out fast there, and then after a while running with excess clearance.
However for many applications mix and match is fine, I have done it often enough for non critical bearings, where the more worn side got replaced with a less worn used one, and it went on running for a good number of years again.

You want crazy things change a fan on a DKW air cooled engine, which is powered by a pulley between engine and gearbox. Or try Deutz engines, where the power is determined by the number of cylinders, and where you have to remove the single piece head and bore to do the valves. But as a bonus they only come in one size, you want a more powerful engine, it just becomes longer. Had to remove one with a seized piston using a cutting torch, because the crank bolts are on the top, and it would not turn over, even with a 48V jump on the 12V starter. One new pot, valves, piston and conrod later, it was running again. Even wrist pin, because it also had to be burned away to release the pot. Hundreds of them still running around me, mostly in older fire engines and agricultural equipment, they are really hard to kill, other than with neglect.

Had a dealership across the road that accepted cars on consignment. Owner decided to skip with around a year's worth of sales money, on a dealership that dealt mainly with luxury vehicles. Left the salespeople and mangers, and his other partners, to hold that baby. They want him back.
Another also did consignment sales, and then one day, once the lot (converted bank building right next door to me, we shared a driveway) was mostly empty they just vanished, leaving the building open. I secured it with chains and locks, and eventually there was police there to look for them, as it turned out they sold the same vehicles on the lot, and had multiple loans on them with different banks. All went with them, to be sold elsewhere out of country, and only the one Jeep was left, because the engine and transmission was in the rear, and there were no wheels on it.
I got the phone system reposessed, as the phone tech was by me, and I gave him this brand new system, worth around $40k, back to the company. Locked so the building would not be stripped, and eventually it was sold to new owners, who used it as a shop and warehouse. nice convenient parking for them as well, and, being an old bank, they have good strong vaults as storage.

Air line and fittings are wrong, you need to use larger diameter ball stop, with full flow bore, and then a 12mm PU tube to feed the water, and then use push fit connectors, a little more work, but will give the water flow rate you need. You might need to get larger diameter air line coil, perhaps a truck one which might be 10mm, to use, and use a pair of brass push in adaptors to fit the 12mm push on fittings.
Done water cooling on machines before, and 10mm and 12mm piping, and full diameter valving, with the push on connectors, was the easiest way to get full flow out. Anything smaller had issues with flow, especially the air line connectors and the air line ball valves, as the small diameter restriction of the ball really kills your flow rate.

Would add a mechanical thermostat to the radiator, and put in a thermal switch there, that allows the fan controller to only get power when radiator temperature is above 150F, which will allow them to run on for a while when the engine is turned off, allowing the engine to cool down and not heat soak. Under $10 on the river store, and with a 25A rating from Senasys, which will handle the load of controlling the temperature sensor, though probably not the fan load itself. Look for "Snap Disc Thermostat Switch - Circuit On at 120°F and Off at 105°F" and you will get them. Flange mount you put so the base is on the radiator header tank for good temperature sensing. A good extra is to add a small lamp in the cockpit, to show they are on, possibly even using an existing bulb that is otherwise unused in the speedo, that can act for this.

@Triantalex If you made anything other than ethernet cards you had to pay a royalty fee, which made the cards much more expensive per unit, and this meant that the cheaper ethernet card, with no royalties or fee, was going to be put in, as the manufacturer of the PC would be saving a few dollars per machine, which on the razor thin margins they had, was the driver to supply them with it. If your office network is being built, you used the cards the machines came with, and bought the rest of the infrastructure to fit, unlike the competition where the cards cost a lot more, but also the hardware to join them as well, and you had a payment to make for upgrades as well.

Card machines under R500 they will happily do offline transactions, either tap or dip, or magstripe, all of them though will also request PIN entry, and simply store and forward later on. Over R500 sorry, online only. Pretty much all banks do this, they all know how a small glitch can drop the machine off line for a little while for one retailer or the other. Do not think though that many retailers actually know any more how to do telephone confirmation, which will pretty much always work so long as you can dial the call centre, and I really doubt if any stores, other than those small ones that have been around for 50 years, still actually have the Zip Zap card impression machines, and the slips that go with them either. Think those died out around 2000, though I have no doubt there are still some sitting on a shelf in some shops, with nobody there knowing how to actually use them.

Every Toyota by me is very much both capable of driving at 85MPH, and very often they will be driven a little past that for long periods anyway. Only manufacturer that will disclaim drivetrain warranty is MB, where the speed limiter from the factory is 118MPH, and they will warrant you driving at that all day every day. Only if you approach the dealer, and ask for it to be upped or removed, software programmable with dealer tool, will they make you sign a waiver that they will waiver most of the drivetrain warranty as a result, and have you sign it, and explain it to you. Then will do it without hassle, and charge you. Then you can drive at any speed the vehicle can reach, and so long as you have T rated tyres on, which most come with as standard off the floor, or better, no problem. Toyota supplies their vehicles with S rated tyres mostly, the warning is there for those who go to aftermarket, where you can still get A rated tyres cheap. S rating will do 85MPH and still be warranted fit for purpose.

I can guess a lot of the odd writing came from recycled cloth bags that once contained staples, brought as relief supplies to the war ravaged country. You used to get things like flour, rice and other non perishables in either canvas or hessian bags, which were often repurposed as clothing, as there was no cheap readily available cloth. Only in the last 50 years or so did plastic packaging make the cloth obsolete, but you still get some industries that pack stuff in hessian bags, as the plastic ones react with the product, or are going to contaminate it.
Thing in mind is bran for horses, which still comes in a hessian bag, as the horses can eat it as well without harm. They were great bags when empty, just wash them a few times with softener to get them a little less hairy.

To be fair, all beer has, at some point, been urinated out. There is a definitely finite amount of water on the planet, and, as nobody as yet is making beer from cometary ice water, all water on the planet has, at some time or the other in the past, definitely been part of a stream of urine.
Even if you were to take glacier water you will find the same, just that it was more likely to last have been urinated out, in a 21 second stream, quite some time ago, by some long extinct creature.

Well, using the condenser to get rid of the water from the evaporator sounds nice, but it has a drawback in that you now have a nice wet, hot film on the coils, which is going to provide both a perfect growth medium for bacteria, and also will corrode the coils to nothing in 2 years. Evaporator is already going to be a slime paradise, but those pipes and pumps will be clogging up, because of all the dissolved nutrients in the water.
Split units at least you only have to clean half the unit with biocide, but window wall and portable units you have to strip it down, and clean every part with biocide, at least every 6 months, otherwise you get the perfect Legionnaire growth factory, with the product being air delivered right to you. Plus you will find, around the time the warranty expires, that it just does not cool as good any more, because those nice blue coils, which still might actually look nice and blue on the outside, have now, on the evaporator side, been covered with a nice black mould layer, and on the condenser side have turned to white aluminium oxide sludge, also with black mould and slime holding it in place. Then on cleaning, you find that you have an outer layer of fins, and nothing inner left, all now just white powder and copper pipes, lying at the base of the case.
Yes they can give a 10 year warranty on that Matsushita compressor, because they will absolutely last that long, but that warranty does not in any way cover the coils, the batteries, or the inverter itself, which you will also need to replace inverter and compressor as a unit, as the failure of one kills the other. Each one, to the average service centre, without the totally overkill diagnostic equipment at the production plant, will say the other is faulty, so both are replaced together. Note inverter is not warranty cover, and is nearly the price of the unit alone.

By me those tickets get placed on the record system, and when you go to do a renewal you pay, the payment is collected, but the paperwork comes out with the actual slip having a blank where it would have your proof of registration, and you will also get a sheet of all the tickets, complete with the total, that you have to pay them first.
Of course some just ignore them, there is a minibus taxi, who has over 100k of outstanding fines, that still drives around. No policeman will pull a taxi over unless they have at least 15 armed people there with assault rifles.
The delivery is now said to be fine by email and SMS, seeing as post is well known to no longer actually function, so now they email and SMS you the fine, and you can contest it that way, with the email and SMS linking you to the fine, complete with picture. Either you pay, or you contest it (another issue, as those now are to no longer be judicial tickets, rather the traffic police have their own kangaroo court, where it is pay first, then appeal against the entity giving the fine, not an impartial justice), and then the burden of proof is on you.
However I have nothing current, went today to do a renewal, and was in and out in under 5 minutes, no issues.

Funny thing about most large retailers is that they actually do not own the stock they sell, it is all sold on behalf of the supplier, the store does not own it, just is displaying it, and pays the supplier around 3 months later on for the items sold, less any that are either damaged or lost to shrinkage. The big box stores make money in having the money for the 2 months in the bank, and off the 5 to 10% markup they charge over the incoming price. All discounts and reductions are actually off of the manufacturer cut, not the store.
Only a small portion of things, like cigarettes and liquor, are actually paid for outright by the store, due to taxes that are paid, which is why they are so carefully controlled. Also lottery scratch tickets, as the store must buy them outright, and is only guaranteed that they get to keep the money for the non winning ones, and a percentage of the payout up to a floor limit.

Just remember that there are multiple formulations for hot melt glue, and that often it is hard to tell them apart as they look the same, are the same mass and even have very similar softening temperature ranges. This also does very from batch to batch, especially on the cheaper ones where the repacker who assembles the retail packs will often just buy a glue on price and, provided it meets the diameter and length required for the pack, and melts within the required range, it can vary quite a lot as the suppliers have excess of one or the other more specialist product that they want to sell for a low price, or have a batch that did not meet the more stringent tests for the speciality professional market.
I know from working with local glue suppliers that they have over 100 different glue sticks available, almost all of them having diameters that fit the most popular glue dispensing systems, and with some being almost indistinguishable from each other in melting point, but having vastly different uses and chemical make up. For sticking things like cardboard and paper though pretty much any one will do, but some of there are designed for good adhesion to glass and others are for mirrors, where you do not want any attack of the silver backing long term.

@speedkar99 Yes a nominal 12V battery can be charged at up to 14.4V, but should float at 13.8V for most of the time, If you have large loads you put in a 100A, 200A or more alternator, and thicker wiring to the battery, so the alternator can provide those loads with minimal voltage drop. Regular vehicle you have a 60A or 80A alternator instead, as they will provide enough power, and the efficiency is acceptable. Larger current ones have to be bigger, as you need the room for all the thicker copper windings, the bigger cooling fan, the larger rotor and the bigger high power rectifier block in there.

By me you must be in front of a judge within a certain time of being arrested, either to be remanded for further investigation, because there is a strong case against you, or you are going to be set bail. Of course if you have no money for bail, you will sit in awaiting trial, often for years, till your case eventually rolls around, and often the sentence is either time served, or charges are dropped. Court appointed attorney are almost always those who are finishing law school, where they have a year of being public defender before they get their articles, so essentially for a year you are worked like a slave, and barely get any pay for it, handed hundreds of cases a week, and paid minimum state wage for the privilege. Plenty of cases where prisoners sat decades in jail, because the files were lost, till finally somebody noticed this person had not been to court for a decade or three, and the file was missing, and the crime was something that had a maximum sentence of 6 months. Then discharged, and if you want to sue good luck, bookings for supreme court are at least 2 decades filled out already, and appellate another decade past that as well.

@smashed_penguin Only because you paid for the cells that Duracell actually does QC on, the consumer line is identical (down to the tooling marks on the actual cells in most cases, and the lot numbers hidden under the label) to the no name cells you buy all over, just look for ones with the same expiry date, and you find out they came from the same machine line.
The one I want to find is the OEM who did the cells for Proctor and Gamble, as used in Airoma machines, a plain white sleeve cell, but I never had one ever leak, even though I used to buy the intro packs, as they gave 2 refills, and the dispenser, for the same price as a single refill. I had lots of those 2 cell packs around, that were really high capacity, low internal resistance, and which lasted at least 10 years in use, not even leaking when empty. Not even an expiry date, just a lot number on the cell itself under the sleeve.

My bet is they sent the court summons to the registered address for the vehicle, and Enterprise simply filed it and did nothing. Thus the failure to appear, and the suspension. Very good case for them to be paying for all the costs associated with the case, and also being forced to pay costs as well, especially if there are others who got similar fines as well.
You can also bet that, if they had 380 odd vehicles in the one state alone, that they also likely have a similar number in all other states, and that there is a good chance that they also have not insured them either, or wrongly insured them, only registering them in states that do not require insurance.
Very common by me, to the point that if you see one particular set of registration plates from a particular set of areas you can be, almost 90% sure, that it is a rental, because that area is the one with the lowest fee, so all the rental companies have a nominal address in the area, to allow them to register vehicles there, even though they might not actually have an outlet there at all to rent from, just a PO box.

Would not say dealerships are dishonest, but, working in the city in the area called Motortown, with a dealership across the road, and one to the left, those 2 were found doing shady stuff. Across the road did a lot of high end vehicles, sale on consignment, and one day the staff came in and no owner, skipped the country, with all the money for around a year of sales. One to the left the same, just did it for around 9 months before doing the same. I chained the doors up, because they left them open, and it was a massive security issue for us as we shared a driveway. But I bought a car from the dealership in the next block, and it served me well, got 15 years out of it before selling it off and getting another, that is 10 years younger.

The fancy kettle also uses the exact same element as the cheap one, just they use a nice blob of cast aluminium alloy to bond it to the stainless steel plate, and then also put a ring of blue LED's right next to this 150C block of aluminium, to light up the water, so you know it is on. Bets are will the LED dies fail, or the element, but they never last beyond 2 years anyway, with moderate use of once a day for a half kettle of water. Same as the cheap one, made in the same factory, with the same electrical parts.
Of course, if you want a no wait solution you can go buy a Zip Hydroboil (does need 230VAC to run it, and you have to have it plumbed in with both water supply and a steam vent pipe, along with the power connection rated for 15A draw) and have up to 19l of boiling hot water right there when you need it, and never fill it up again. Uses a 2.2kW heater element to boil the water, and keeps it just at a slight boil, in an insulated copper tank, and then has a small auxillary tank that has the float and fill valve, that keeps the level in the big tank constant, but also does not fill it fast as used, so it will not ever be below 95C. Thermostat uses the steam, venting into the small tank, to trip off power when the small tank lid hits 60C, so the main tank is always just short of boiling.
A few sizes depending on use, from an office with 4 people, to a hotel that does morning coffee and tea to 200 people that all want boiling water over that hour of breakfast. All the parts that fail, tap, element, float, valve, safety switch and thermostat, are spare parts, and easy to change out as well. Just the price is a little more than the $15 kettle at Wallyworld (expensive, the cheap ones here are $10, with a 1 year guarantee, and actually do often outlive it), so be prepared to shell out $847 for the most common 10l model.

Many vehicle dealerships also do a full video walk around on all vehicles coming in for service, to show that, at reception, what was working, what was not, and also things that are worn, like wiper blades, tyres, suspension and such. Yes adds another person who does only that video, but seems to be worth it to the dealerships, reducing the amount of claims, as you sign it in with a video, and all damage and such noted down, with a signed sheet that they also record you on video signing.

@aaakkk112 you mean the cleaner I used, which needed a 44 gallon drum of it every time the solvent was changes was bad? But that was about the only stuff that got things clean, nothing else would work in that fast a time, with vapour and ultrasonic agitation doing the job. 30 seconds to clean, and when it was time to change the fluid, too dirty for our demands, I called and got all the GSU dirty stuff in for a few quick batches, and really made the fluid dirty, then it was dumped into an empty drum, the tank washed with clean fluid, and then it was filled again with the drum, the little bit, around 10 gallons, being there to top up as liquid evaporated and went with the cleaned parts.

Data in the VBI was generally a SMPTE timecode for the source video, used to display a time counter and frame number for the use of the editor. The other info was close captions, and then you could also have alternate data streams that contained things like title . This came from the original video tape, either Umatic, Betacam or Betacam SP, and was simply transferred to the video stream either by the TV stations or by the duplicator. TV stations would often strip out the SMPTE codes to instead add station control codes, transmit flags ( is this for certain areas only on a national broadcast, or to add local adverts during breaks) and the local transmitter text data, but line 21 would generally be left alone.
The Macrovision blocks were generally not going to interfere with the timecode, but the only thing was that the video clamping would be confused by the ramp and would thus result in the decoder not getting a good signal out. Professional VCR units had the ability to turn the video AGC on and off so that you could then record the Macrovision info onto a tape without interference, and also turning it off on playback meant your video was not going to suffer from data corruption during the edit stages as well, though you only put the macrovision on at final dub stage, so that it would have less effect, as it still did cause degradation of the video by not giving as good a vertical lock.
Professional VCR units would record macrovision effortlessly, and Panasonic made a lot of semi professional ( Prosumer) VCR units with this available, mostly used for home video editing where you also had generation loss and not having multiple AGC actions lessened the video degradation somewhat. You would have only the camera AGC enabled to handle the initial shooting light variations, then use the edit deck to do your effects, cuts and non linear editing ( you needed an edit deck, and also at least 2 VCR units slaved to it to do the non linear editing before HDD recorders and digital video) and record to the master tape. The edit deck could also do the audio dubbing in linear stereo in a second pass, though HiFi stereo required you to have the audio dub already set up to record.
You could get really good results out of that, as good as the best professional edits, as good as VHS could deliver both video and audio wise. just needed a good source video.
As to the Teletext and such, pretty much European TV sets, or at least anything that used the Phillips chipset for TV jungle processing had text built in for either free ( for the later chipsets where everything was in one chip and a front microcontroller with an I2C bus connecting them) or with only a small second text processor and a few control bit changes. Siemens also had a set of chips that did this as well, so any of the European TV manufacturers ( Grundig, Phillips, B&O, Normende) and almost all of the old satellite TV decoders as well did both close captioning and text even on the basic sets. The USA had their own chipsets, and most of the European chipsets did out of the box PAL,NTSC in assorted flavours, and SECAM with either no added changes or with only minor changes, but the US ones only did NTSC.

There are still worse ones...... Where the job first requires you to drain coolant, then remove injectors and inlet manifold, then you can see the starter.
Then you get some vehicles where removing the starter first required a cutting torch, because you needed to cut a hole in the panel, because the manufacturer welded the engine bay together, so you either made the hole, or stripped out the entire engine and transmission. Cut the hole in the light weight quarter inch steel, and use a welder to make that into a bolt on panel, was the approved method. 16 ton vehicle, of which 10 tons was just the body itself, welded from steel plate up to an inch thick. Standard accident repair kit was a can of yellow paint and a brush, because not many had really managed to ever dent one. Not that what they hit survived, but those that went to the scrap yard were truly broken.

@robertwilson2007 Much better than never renting, because there are a number of sites where you can look up VIN history and get a report. Plus if you use Uber, Turo, Bolt or any other ride share, or even a matered taxi, there is the same risk the vehicle there is also stolen, and much higher for the gig economy, as there they do use stolen cars and fake plates, because the car running on the road is how they make money. By me the minibus taxi industry has a very high theft and hijacking rate, because if you have 8 taxis with the same registration and rank number, but never have them in the rank at the same time, you can make a lot more money. Spread them around a few routes and the rank bosses will not be any the wiser, just thinking you have a few drivers for the same white Toyota Quantum.

@BrainAbsoluteZero Yes, but since most brands are both cheap, and likely available at home Despot, simple to first go see the lock model, then go and buy the exact same lock, come back and drill it out, then replace the broken parts. Now you have legit key, and do the same for the other doors, no need to drill as they are legally required to open from inside, so now have a near full set of keys. Then sell furniture off quick, leave minimal around and use the ID you likely got there to make the fakes, and flip the place, as you have "legit" ID, and keys. Most houses the locks are both cheap and common, so easy to replace, as not many will go and order specially a decent Abus or Schlage lockset, that is rated to be secure, they buy the lock by price and appearance, price first. Been to many houses where the lock is cheap, as in $2, because it was the cheap option at the hardware store. Great for indoor lock, but i wanted a little bit better for my house, so spent the money to put better locks on, and a decent set of physical security as well.

From the cost point the heat pump and non heat pump units use the same compressors, and the added cost is often only the extra wire to the outdoor unit to operate it, and the extra relay on the board, along with the reversing valve and the half meter of extra copper pipe. Cost difference is around $20 total between the heat pump and non heat pump versions of the identical otherwise model, and the only time the non heat pump unit is really the best, is in a tropical climate, where you want cooling all year round, and even there you might want heat 2 days every 5 years anyway, for the odd cold snap.
Only other use is in server rooms, where you have a large near constant heat input, and never a need to actively heat the place under any circumstance.

As to the optical range question, it is more the proteins that are light sensitive, which were originally found by natural selection, are sensitive to light in the red to blue spectrum. Majority of the light output of the sun is in the IR spectrum, but the proteins that are sensitive to it never were selected for, instead simpler more stable ones, that were sensitive to the spectrum we use, gained the upper hand. There are not any structures other than the pits in vipers, that are sensitive to long wave IR light, and making an eye out of those would result in one that is both much larger, much less sensitive due to lower photon energy, and also much lower resolution. Basically eyes would be the size of your head, and you would still barely be able to see if somebody was holding up 2 or 3 fingers at 10 feet away. In terms of optical ability you would have 1/20 vision, barely able to make out the top line of the eye chart, and legally blind.

While I am in there, involved chiselling open a ceiling at 10PM, so as to get the buried junction box open, so that I could make a new cable change direction. Luckily I did have 100m of cable for the conduit already, and got that floor free of the old rubber insulated cable.
Another involved removing nearly 20kg of old cable, inside the machine bowels, and replacing it with 100m plus of new, because I could not be bothered trying to trace where that spaghetti went, so took the original diagram and made the unit match it again. Whole load of mystery relays came out, including some tucked up in the wiring area itself, behind the steel cover, which in turn was covered with a whole host of pneumatic valving. Only used 4 packs of cable ties there.......

EPS flexible coupling in the top of the motor is faulty. There are some bushings there that are known to fail, so look up the Hyundai parts list for the EPS, and you will find them there, as a known issue, plus the top bushes also wear. Had exactly the same on a Kia, and they use the same EPS motor and drive, so the universal was not to blame, but you need to look a little further up the shaft to the EPS unit. You need to pull the steering wheel, strip the column to get to them, but otherwise not too difficult, and all you need to do is an EPS relearn afterwards (lock to lock to get it to figure things out) to finish the job.

Yes time for Chloe to get a lawyer, and sue the renter for all the damages, plus the cost of the loss of vehicle. The renter can claim somebody stole the truck, but as they were the negligent party in claiming they left it with keys in it, and a quick subpoena for the location of the renters phone location logs will very likely show both active calls and data use, plus also that the location of the phone corresponded with the freeway route at that time as well. Then they can also face the added charges of lying under oath, making a false police report, and insurance fraud as well. Pay the damages plus all legal costs, just needs a phone number, a semi decent lawyer and a subpoena to the phone provider for the metadata for that time period. All the data will be handed over immediately, and will show that the renter was driving, or at least their phone was in the vehicle, and was actively being used, and any calls made or received (the likely cause of the lane departure) can easily be traced back to them as well. Do not think family and friends will want to lie when the result is a 6 month prison sentence.

@rge24491 Friend had that, he bought a property that was an estate that took 10 years to wind up, and his water bill was constant. Finally had to find the meter to shut it off, because a pipe broke, and after some digging, and chopping down a 5m tall sisal plant, the type that has a million sharp reasons to stay away from it, the meter and valve was found. Next month the meter was read, first time in a decade or more, and he got a credit on the bill, because apparently they had been estimating usage for 10 years, with the house vacant, other than a monthly mowing of the garden, and a guard who came around once a week, so all the water use was a tiny amount from when it was being lived in.

Had a couple of tickets for that, and the standard is to take a photo of the out of order meter, and drive down to the metro police office. Then you give them the ticket, show them the photo, and generally they would immediately cancel the ticket. They figured if you were willing to go down there, you would contest the ticket, so cancel it as that makes more money. Of course now it is impossible to find a meter that works, they are all vandalised, all that money inside, and the stainless steel case, makes then a target for scrap metal thieves. Even the ones outside the city hall, and the metro police offices have all been destroyed. Go to the metro police and you park illegally, because they all also park illegally, and if they do fine you, just grab a few photos of them illegally parked next to you, and go back in.

I almost had that the other day, but, being paranoid about things, i always check battery cables twice before connecting to jump a vehicle. Does not help that I only had the one can of battery terminal spray, red, on the terminals, because I ran out of the green with only a half can of the red left, after also using it on all of the chassis ground lead connections in the engine compartment on other vehicles. So now all are red, though positive is also hidden under a cover, like many vehicles now are, to add to the confusion. But with a double check, no issue, and the heavy leads I made are plenty capable of starting the other car, even with a totally dead battery.
Yes the cable tie on tape is needed, especially in a hot engine bay, though another trick I have often used is to use PVC weld on the tape, not the coloured one the USA has, but the plain one made with polystyrene in acetone, which dissolves the PVC in the tape to make a solid join that will not come apart with time or heat.

@1982field Yes and BMW will gladly, if asked, change that limiter to 200 if you ask, or to well into the redline of the engine, so there is no longer any rev limiter at any gear. Though you also will sign a legal waiver, that in doing so you also agree they are in no way responsible for any consequences, and that you also voluntarily waive any and all drivetrain and other warranty, along with motorplan, on the vehicle. They will still service it, but you now are liable for all costs aside from oil, filters and spark plugs for the original motorplan duration. No top up or extensions at all. That $10k sunroof packs in, sorry here is your bill, that $10k driver's seat has an issue, and needs replacing, same again.
MB limits to 190kph out of the factory outside of Germany, in Germany they do 210kph, as that is a figure they consider good for the unlimited sections of the Autobahn, and it is scary just how fast, and how little fuss they make, getting to that yellow glowing limit triangle in the dashboard.

You could assign much more blame on yje ship owners though, for failing to both provide lifeboats actually rated for the cold regions, and also for the lack of maintenance of them, very likely a few years of them using the lowest cost bidder for service, and thus for them being pencil whipped at service time, possibly with only one being done, and the rest sort of being done, and of course the same one each time being selected for checking.
Also the failure to check the watertight doors properly, and a design flaw where the plumbing going through those doors did not have isolating valves, which would have prevented the water from spreading via the plumbing, a known flaw, and one which has sunk a good number of ships as well. A set of valves at each door, gate valves or knife valves, will have stopped the water ingress greatly, even with leaking doors, to the point the bilge and fire pumps could have kept the ship afloat long enough to make port.
The valves would have been mechanically linked to the doors, so that they close with the doors, though you can always close them manually, but they will not open with the doors, needing a manual reset. A safety feature that ensures they get checked with each test, and simple to add remote flags to show status as well in engineering.

@-danR High pressure gas comes into the check valve, then there is a orifice plate to provide some flow restraint, and then the burst disk. In the space between the 2 units you can add a simple leak detector. For the oxidiser just use a high pressure electric feed through and a plain low carbon steel thin wire that will be corroded open if there is any leakage, and similar for the fuel, as it is also corrosive. Cheap, and can be integrated into the flange and orifice plate as well with ease, along with a pressure test port. You could also add in pressure transducers and a low pressure fill with gas, but pressure sensors that will survive that fuel and oxidiser are not cheap, nor are they low mass, as you need a diaphragm and transfer fluid to keep from melting the silicon strain gauges, which are ironically the cheapest part of the sensor.

Had a landing where we were accompanied by a fire engine with a running foam cannon, just waiting if the crash would occur. But luckily just a failed undercarriage switch, which the pilot, co-pilot and flight engineer, plus me as the mobile data link and safety harness, connecting the flight engineer to the aircraft, as we both were leaning out the side door and looking under the wing, were saying, as the gear did absolutely look like it was coming down correctly, and locking in position.
However, absolutely the second smoothest landing I ever had, you could barely tell when we had all 3 wheels on the ground until the engines spooled down. No brakes, but a really long runway, and we had a lot of it in front of us.
Best was a 707 pilot demonstrating his cross wind landing capacity, while we had seen, and heard, the 2 planes in front of us land on the same single 16 km long runway.

Here by me all car washes the customer handles the keys themselves, never the car wash. They wash, guide you to a bay and then you keep the keys during the process. The nearest one to me charges just a shade over $2 for a wash, during the hours of 9 till 3 Monday to Thursday, their typical low time, for a standard sedan or hatchback, but outside those hours the price is $5, and the price for SUV's and light pickups is $5 in low time, and $8 in peak time. They normally are full pretty much all the time, I used to take the work van through it in the low time for a wash, as it was the easiest one to get through, and I could make the trip work out easily for an empty van.

By me they have, in the drunk van, a judge along, who is there voluntarily, to work a shift to process the orders, and then the phlebotomist, from the state laboratory, will do the blood draw, seal it, get you to sign for it and put it and the paperwork in the chiller to process at the end of the trip. Only comes out Easter and Christmas/New Year, as they then generally have the highest number of deaths and DUI arrests.

@777CaptMark Yes, a simple easy document, which covers pretty much all this case, and also if the vehicle is stolen or has an accident in the interim time. Dealership should have this as part of the purchase documents, just fill it in with a zero day clause in the case financing is done before leaving, or if it was paid for in cash fully. Surprised there is not anything like this already, unless the dealership messed up, or they did not want to pay any costs for the extra insurance, say for vehicles sold on consignment.
Would have covered the one time i saw a sports car which had an incident getting on the transporter, where the one ramp was pulled loose by a little too much pedal application, leaving the vehicle balancing in the air, with one side on the ramp, and the other side floating in air, and hard on the edge of the trailer bed. Engine off, brakes on hard, as the driver did not want to change anything and drop it 1m to the ground, till they had gotten a high lift jack there, and chocks, to hold the dangling parts, and then use another to lift the front, and get it fully on the transporter. Did not want to guess who drew the short straw to phone the owner, as those were all sold on consignment.

Yes, any fixed camera can do this, and your most common camera is a red light unit, which these days does not need a flash to take the video image in the most case. The flash is merely a way to get a better image to identify the driver, as the bright flash with short duration reduced motion blur, but to just be able to extract plate data, make and model plus colour with video is easy these days, and all it needs at night are working street lights. Fixed speed cameras the same, the flash is there to have a definite correlation between your tyre being on the sensor cable to trigger the measurement, but even as ANPR cameras they are quite able to measure speed, especially the new laser ones, which constantly focxus on a section of road and measure the velocity of the vehicle in it, triggering with breaking the limit, and the IR camera part records an image with the laser spot on your vehicle, while the colour camera does the colour and driver details, plus both can be used to get plate data.
Even cheap home security cameras now are available with 4k resolution, and 5k and better are dropping in price, so you can literally do that CSI zoom and enhance on the still frames from the video, or even zoom in a section of the playback video if needed.

Nice to see actual spanners, not just the adjustable nut rounders.......😀
But those cylinders are definitely at the right place for repair, and as a bonus all lathe work, no welding of eyes on. Brakes look like you can get them off the shelf, though with the age the only issue will be the thick layer of dust on the new old stock spares. Funny how the label of the reliner was still so shiny when the drum finally came off, and just how manky the rest are. Will bet the others are as bad, so when you order spares get 4 kits, as the others will probably need it as well, but they should be common enough.
Might as well order 4 actuator units as well, even if the one is "new.....ish", so you start off with good brakes. With the work you do you want to be able to stop fast, and even braking is important to keep the jobs aligned.
Just watch out with your avian supervisors, leave them some shiny things around, like wrappers of aluminised foil, so they will take that, and not fly off with assorted nuts and washers as nest decoration. They might even start to bring you money, to swap for the snacks, and I would say they would love it if you brought them a nice very ripe papaya from the supermarket, nice and yellow, and full of tasty seeds. The local ones by me love them, I have a problem getting any off the trees.

@michaelmclachlan1650 They all still like shiny, as I found from the African and European starlings by me, who will eat it, even if they are in general mostly omnivores, with tending to be heavy on the meat side. Eminently trainable birds, I still see two who I evicted from a nest spot, who still remember me, and will alarm call whenever they see me alone. They were determined, so I had to remove the nest and the site entirely, as they decided to rebuild, despite having put generic hotfoot down there. The mud pile was done nearly overnight.

Knocking is the bearings coming off at the bottom of the travel, and having a small gap between bearing face and the outer ring, and then coming back into contact later on as the inner section rotates, so it takes load again. Hard to fix, short of having the stud shafts with the nut section slightly eccentric, so that you can adjust them after installing, to give a larger preload onto the outer race so the bearing and race does not separate. Preload per bearing will have to be about the load applied by the vehicle mass, so around 2500N.
Long term those bearing outer races will fatigue and crack, they are not designed for this, you have to use proper cam follower bearings to get good life, as they are thick walled to have fatigue life much higher than a regular bearing, and not to deform under point loading on the outer race.

Yes, brings back memories. I picked up an old luggable with a ST251 in it, that had a different firmware in it, that would autopark the heads after a quarter second of inactivity, so running things on the 80186 processor that needed disk IO but which were also compute intensive would result in a few hundred strokes of the drive mechanism across the disk, as the auto park activated after each lull in access. Same with the otherwise standard Shugart 5 1/4in drive, which would home itself after each track read if the next read did not occur within the quarter second, and also spun down the floppy disk after a half second of inactivity, making it really slow.
As it was fully expanded with a full 1M of memory, it was capable of running MSDOS6.22, a big step up from the MSDOS 4.0 it came with on auction, though the screen itself, a EL backlit TN LCD, was very poor by then, the EL backlight was on it's last legs, and very dim, while the TN display had both slow response, and an incredibly narrow viewing angle. To see it you needed to be in a dark room, normal office lighting would simply wash out the display totally. Still have the ceramic 80186 processor though.

@paulstubbs7678 Had to recover a failing Seagate drive on one, it took a few hours in the freezer to get it cold enough to allow me to get all the data off. New drive, due to the BIOS, had to have that 2G jumper put in, as Netware 3.11 was not happy past 2G of drive space, though the data was all only around 1G. Did find a good use for that extra space, made a second partition, and formatted it, and made it only visible to the administrator. Now it was used to take snapshots of the database running on it, so I could do a quick copy during lunch, and then again in the evening, and have a snapshot that was generally only a half day old. Was useful, plus also month end I could carry on and do a pre and post month end backup as well, just in case something borked. only 100M anyway, so I could fit a few snapshots onto the 1G partition, and at leisure write them to backup without slowing the system down much. That screensaver did roll over once or twice as well. 3 NIC's, to segment the network, seeing as it was still mostly 10M NIC's, and a lot were 8/16 bit ISA cards as well. At least a big step up from Arcnet......

Lot of politicians and judges will also appear on that list, seeing as they likely are lawyers, and at some point will have been through the companies blocked. Will they also ban the staff, like paralegals, secretaries, runners, drivers, and the companies that do cleaning, maintenance and such for them as well, along with the companies that provide services for them, like phone, internet, power and water?

@GoldOxide8463 That is the thing, those that get away with it are never caught. She messed up, because she had it running too long, should have had the fake run for 3 months, then be a no show and terminated, then leave for 3 months, and rinse and repeat. Big enough company, or government, and you find hundreds of ghost employees, who look real on paper, and often the tax is applied to whoever was the unwitting SS used.
Yes the failure is using a bank account that can be traced, you need to have fake ID to open bank accounts as that person, and get the money using methods that give cash out, like using an ATM, with disguise, as they all have good cameras now, or drawing at a cash payout point like a store. Of course do not use your store loyalty card there either, and remember the 100 cameras, that record every step, from the moment you enter the parking lot, and even the street.

Here that stainless steel would be gone the first night, ripped out, or cut off and taken as scrap metal. At nearly $1 per kilo stainless steel will vanish fast, though of course the ever popular thing is to steal every bit of brass or copper that can be found.Unless you bury it in thick concrete it will be taken, even if it is a 10cm length sticking out the wall, or a shut off valve. I just have given up, and am using PEX pipe every place outdoors, as that at least is cheaper than copper to replace, because it will be chopped off for the tiny bit of metal in the crimps, or the brass fixtures. Go to the police and they will not even open a case any more, because it makes their statistics look bad, having 200 cases a week minimum.

Failing coils, so the ECU increases on time on the injectors to compensate, thinking from the misfire that it is running lean, as the oxygen sensors when hot are giving implausible readings from all the carbon. Then long on times heats the injectors, causing the marginal ones to break down and start to be intermittent. Higher resistance is in secondary side of the coils, primary side of the coils will be in the low ohm range, typically under 5 ohm, as the ECU is the one setting coil current and timing, and anything over around 5 ohm on the primary will never be firing well. Will bet as well if you take one of the fake coils, and slice it open with a grinder, that the wire inside is the horrid CCA wire, silver in colour, and this will always fail with time.

@charlie15627 The Russian missiles are not as well characterised as bombs, where the designs are held to tight tolerances, so the casting is machined to a very precise profile, the fill mass is carefully controlled, and then the balance point is adjusted to put all of them at the exact same balance, so all will fly the same. My grandfather was the one who made the patterns for the bombs in the war, and cast them, then they got filled and shipped to the UK and allies. the same bombs are still in use, as the newer weapons systems were also calibrated to use them, so they kept making them to the same spec.
The mass produced rocket is not as well controlled, and as well as the propellant fill ages it varies a lot in burn time and pressure, so they have very little consistency. After all they were designed to close in point and shoot application, not for precision long distance work. I doubt that they even can get the same batch and lot numbers per load, all likely being different ages, different manufacturer, and different storage locations, all brought there fast to be used. Also probably more than half of them are duds, with the famous QC that the USSR was known to have for military stuff that was produced, where production quotas were the only metric looked at.

Thing is Fedex hired the contractor, then sets limits on how long they have to get from A to B, ignoring little things like traffic, tolls, weather, legal working hours for truckers. Thus you get them saying that facility B is 55 miles from facility A, and the driver must make it from arriving at A to pick up, to delivering at B after loading a 20 ton load of assorted pallets, in one hour, or face penalties of $xx per minute. Never mind B is at the other side of a city, there is no direct route, other than 80 miles of country road or residential streets with a 40MPH limit or less, there is a toll bridge between them, and this has to occur from 4PM to 5PM, in rush hour traffic. Also the loaders took 30 minutes to decide to come out to the truck, and 20 more to load it.

@ben_doom1958 Been in a helicopter doing that, memorable when you are sitting looking out the door, and above you is the ocean, and beneath your feet is the sky. You would not think 16 tons of helicopter can actually do that. As for transport aircraft being underpowered, they are suprisingly robust, as I also later on had the dubious experience of hearing the 2 ahead of me in the circuit landing, hearing it through the sound proofed walls of the third one in the circuit. They scrubbed all those tyres to replace in a single landing, and left a pretty impressive cloud of burnt rubber as they jackhammered the crabbing aircraft down on the runway.
Of course the pilot flying the one I was in had much better cross wind capacity, and came in with a hot mic, reading off altitude till he went silent at 3, and after 5 seconds, when he commented for full reverse thrust, that for all those who were waiting, we had landed 400 feet back from there. No noise, no bump, no smoke. Interesting flight, got to watch air to air refuelling, the success, the fails, and the come back with a very clean plane, after doing too fast a disconnect, and getting washed with 500l of Jet A, promptly flaming him out. Bank off, aim level and get to practise that flame out restart procedure, that before had only been done in the static simulator, and come back to do it properly again. Passed that phase perfectly, did not get the package of the torn drogue sent to him as award. Same week also had to jump start helicopters, all that training as apprentice sure came in handy there, as I had to learn the entire airframe electric system, and read all the documentation as well, and a lot of it did stick.
As to the toss bombing that is CCRP, different from the US standard of CCIP, and yes the bomb will go a lot further.Did hear of one pilot who did that, and he was a little hot in the pull up, and missed the target by a little. Also missed the bombing range entirely as well, and the farmer got a new tractor out of it as well, because the practise round landed near him in the field.

@apolakigamingandmore6376 Flying inverted is easy, you just have a limited time to do so, as you are very rapidly scrubbing altitude and velocity, though a lot of fighter aircraft are designed to be able to fly inverted no problem, though, due to the internal inverted flight fuel tank, held in the final fuel tank, only holds around 30 seconds of fuel in it for this, before you have to fly in a normal orientation again. Also a lot of the hydraulic systems are going to run into issues, as they lose the fluid in the pressure reservoirs, as the pumps are no longer able to scavenge fluid from the sumps.

@gags730 Central Africa, where the cost of shipping was high, so when he sold the municipality a new set of US built Cat dozers, their first job was to dig a big pit, and push the old fleet of British made, Rolls Royce Merlin derived engine powered dozers into the pit, and cover it. New ones were both more powerful, much more reliable, and had half the fuel consumption of the ones they replaced. Reason to push them was because the old fleet only had one working left, and it was not capable of pushing another, so it was the only one that drove in under it's own power. Shipping stuff out took space on a train, that would otherwise be used to carry copper anode blocks from the mines, so the cost of freight out was high, but incoming was cheap, as the cars had to come back anyway, so filling them was almost zero cost other than the fuel.

@TrekkerMoto Mercury switches are long gone from SRS modules, they all use MEMS sensors these days, which are both very reliable, very fast and also position insensitive, so will not give a false output if upside down. The controllers are also permanently powered direct from the battery, so will delay for a few seconds on power being connected for self test, and if upside down will just set a fault code, for the sensors being in incorrect orientation. Central module and then possibly others in crumple zones to provide info on rates of crumple, so the main module can determine impact force and direction, and thus which airbag outputs are going to be fired. Also seat occupancy detectors, so that only the driver and passengers actually in the vehicle are protected, and the others are not fired unless needed.

The popular Kerosene stove used here, almost the most popular cooking method, as it works when the electricity does not, and gas has a high initial cost for use, does not need a starter fuel to use, just pump it up and get it high enough in pressure to spray a fine mist, then light, and it will stabilise down to an even heat in seconds.
Same for the lamps, though there have been a few models recalled because they had soft solder on the "brass" parts, which melted in use, and you had the whole unit pop apart and spray hot boiling kerosene, here paraffin, all over, with a nice ignition source for the hot gas as well right next to it. Saw racks of them that had been seized by the regulatory body, ready after the case to be taken and crushed, then sold for scrap metal.

Funny though My 2001 VW I only ever changed bearings all round once, rears because the drums wore oversize, so a new set of bearings with the new drums was a kit, and front one hub at a time, as front hub assemblies are not that much more than the bearings alone, and save you that 2 hour cursing session getting the bearing block out. But done that, they were out of stock at the time, so time to use the big hammer, the big steel drift and the piece of pipe support instead, plus a lot of lube and a bit of heat to break the rust free. New went in with a layer of grease, so changing would be easier next time.

My friend lived in a flat where I could change lights for him easily, just lift my arm above my head a little, and touch there. Worse was my sister, where changing lamps involved coming in with first 5 strong people to move the concert piano out of the way, then place plastic sheet onto the carpet, then wooden duck boards, then build up scaffolding to the inside of the atrium, where the lamps were. Thus those only got changed out when every last one was dead, and they were made to last a long time by being run off a dimmer switch, set to half brightness. Also coincident with the scaffolding going up the atrium windows would be cleaned on the inside, the outside cleaning being done by the rain, because no window washer was wanting to climb up the roof to there to wash them.

Funny here paying a bill at the store you pay nothing extra, the payee gives the store a commission fee, not the customer. Many banks now also will not charge any fee drawing cash at a till either, because the shop covers the cost of handling the cash, not the bank. Some banks you can even deposit cash at the till as well, they literally act like a bank branch, with zero fee to the customer. Quite a few of the more online banks now offer this, as they have almost no branches, you interact with them, from opening account, to doing all transactions, either via phone, or online via app or phone call, and use merchant shops to handle the money side. Card will be couriered to you as well, along with any documents you might need to sign.

MB with the regular vehicles comes, by default, with a hard speed limiter, set at 100MPH/160kph. Plenty fast enough for 99% of all the users, but, for free, they will change it up for you at any dealership, free, you just sign the waiver of the drivetrain warranty, and your insurance company gets notified of the performance modification (in all insurance contracts for this anyway). It is not deleted, just set to 300kph, as very few models can actually go to that speed anyway, and for those that can they simply set to 400kph. Even in Germany it is that way, so you will see them cruising on the Autobahn unrestricted sections at 160, with the bright yellow "Limit" warning on the dash. And yes it will get there very fast, especially as you cannot really feel acceleration inside that sound proof vehicle. Plant the go pedal at almost any speed and it will drop 2 gears and run to redline, before smoothly changing up.

The indexing should be aligned with the dowel pins, which Kurtis did not use, instead relying on his ability to do the alignment by eye before tightening the capscrews down that hold it. Easy enough once installed to undo and use a large flat surface (chuck front) to check and set, then bolt them down hard so they do not move.
As to different measuring tools, depends on tolerance. If a mm is close enough then a steel rule will do, if you want within 0.05mm the digital vernier is good enough, and if you need to have the tolerance within 0.001mm then the caliper, along with the right calibration blocks, is the tool to use. Also the caliper is used if he needs to have a difference in diameter of a specific amount, like for the shrink fit, so that the final difference is such that it will not shatter the outer while relaxing to equilibrium temperature, yet is not so loose that it will either move, twist in use, or fall out under light loading. A small band, thus the need to have an accurate and repeatable measurement.

Comes from teacher pay and advancement being only done on pass mark, and nothing else. So the teachers are going to do whatever it is to get to that mark, ignoring everything else. Just like taking any office, and making the only way to advance be by writing up orders, where you then, because you can also cancel orders, get hundreds of orders written, processed and then cancelled, or returned as unwanted, because the salespeople are not dinged for returns, only for writing orders, so they will write everybody an order every month even if they are not wanting anything, or even a customer any more.

Anybody notice the bump stop O ring only was installed later, it was left in the tray, even though the speech about checking all parts have been put back in place.........
The old quill can still be repaired, just take it apart and cut a different taper onto it, or cut a thread and then machine a steel rod to receive it, and put the taper on the rod, so you get a new section. You could even them machine a thread onto the new rod to match the chuck.
Old chuck is easy, still good chuck, so machine out the hole slightly ,and then put in a morse taper adaptor, and use it as a lathe drill chuck.

Brake lights, the thing so often not functional on many vehicles, where you might only have the centre high brake light working, more because it has 5 3W filament lamps in it, that are not run as hot as the others. The LED versions also fail, or the brake switch had broken and stuck on long before, burning all the lamps, incandescent and otherwise, out from overheating. I see on average around 1 in 10 vehicles with one or more lights not working, and this includes both brand new, as in still with paper plates, all the way to vehicles that are mostly describable as rust and body filler moving in close formation.

Funny enough common here in cabinet making, mostly because you can easily fill the hole with filler and hide the screw, but still dig it out later if needed. Only problem is if you have a mix of screws, all the same dimension, but there are a few of the other type mixed in there.
Last time I had that, was late on a weekend, needed to put those last 3 non Phillips screws in, and they were all Robertson. I used a hammer to put them in, like a nail, because they were not critical, and were going into chipboard anyway. Next time I went to the hardware got the set of Roberson drivers, because the remaining screws are all that.

Would add the helicoil and clones are really good, but the timesert is the best for handling pressure and liquid. Would say that for the tension tests you really need to not use cheap bolts, but go instead for capscrews with a rolled thread, as I have found the 8.8 capscrews are stronger than the helicoil inserts, and will actually pull them out before the bolt fails.
If you go to a M10 thread, go and buy from Ford CVH engine head bolts, as those are incredibly tough, as they are designed to have the shank stretch, but not the threads. New ones should easily be capable of doing the insert to destruction, as the recommended method to repair damaged threads on the block is to tap down to the base of the hole in the block, and run in a few inserts, or a very long one, to provide a large grip area, which will never let go, the bolt itself will snap first, though the torque to do that is to go to 90Nm, then a full turn and a half, instead of 2 90 degree turns in sequence. I have used those bolts a lot in machinery, to have a really good high strength connection, though normally regular high tensile nuts are not up to the task, always have threaded the steel to take the bolt instead.

@mr2miach Thing is car body kits are not run under much strain, as they flex a lot, so the attachment points have to penetrate the material so it is held in place mechanically, as the glue join will flex, and eventually pull the fibres off at the surface. Here the issue is the join has to be orders of magnitude stronger, and any penetrations for bolts would have resulted in massive stress concentrations on the fibre area around them, making them fail quickly. Car body kit you will see crazing of the paint surface before the fibres themselves are compromised, so you are running it under low strain, but here it is run close to the full pressure rating, with little margin for any error, and cycling will slowly degrade the bonding to the point of failure.

Hp is not what it was though, having been made sweeter to appeal to US taste, and thus losing the rest of the world who wanted the original more bitter one.
The reason for adding the salt was that trench warfare was generally hot and muggy, so you would sweat a lot there, so the added salt was needed, even above the original salt in the corned meat, as you otherwise would lose too much salt in sweat, and thus have poor condition troops at the front line. Even in winter thy bundled up warm, so sweating was always a thing.
Modern day hot industrial plants they will always have water available, and some plants go so far as to have water chillers every section for hydration, and an important thing to add is salt as well, either in the form of salted snacks or as extra salt packs in there as well. Doing temp work in one I was drinking 8l of water a day minimum, and took along lots of salt packets from fast food places as well, because you lose a lot of sweat working in places where it was 40C plus. lots of fans as well, and many of the stations they had literally welded the fans to a length of chain, which in turn was welded to the steel building structure as well, because if they had used bolts everybody had tools to undo those, and move them to other places. I did find some that were not welded down though, at one point we had 6 just to move the air there, and it helped a lot. Not little fans either, they were the clones of the Big Ass fans, basically around 30kg of steel so as not to blow over.

I would guess they buy the stuff, and then return it at another store, after making a copy of the receipt, because thermal paper does fade, so many people store copies to carry the warranty. Thus the copy is used to do the return, or they could have been more classy and simply gone online and bought the exact same printer and paper, and printed them their own copies of the receipt. Printer easy, and the paper as well, as the stores often do not actually control this, and leave rolls by each register, where you can simply toss one into the trolley of stuff, and security will in the most cases not even notice it if they check, assuming it dropped there accidentally from the POS desk. Then you have a roll of the right paper, the right printer and away you go.
By me the last few Post Office receipts are all printed on lottery paper, as they do not have the plain paper, but plenty of the lottery rolls from a previous operator, and they fit the standard thermal printer.

@mikelarry2602 Disease caught from another person, like flu or the other virus that you find so common these days. The other party knew they had this, and did not take precautions to prevent spread, so that is an action they did, and thus a reason to expect to be actionable in law, in that they were aware, knew there were reasonable precautions they could take to prevent transmission, but that they deliberately did not take them, and deliberately infected another person with a life threatening disease.
Could even be classed as assault with a deadly weapon if you look at it, in that this does materially affect the wronged party in life length, and massively increases the chances of them dying early from debilitating side effects of the infection. That they might only see the effect decades later, or not, is not going to be an issue, the average life expectancy is demonstrably lower now, and the treatment is very invasive and debilitating as well, along with not being more than palliative.

@red5standingby419 $120 million plus in federal credits, that the Nation will want to claim from the feds, at a minimum, will mean that the LLC will be definitely subject to federal investigation, because the US government will want to get those credits back, and they have endless pockets, plus will be able to pierce those LLC and Inc companies, at a minimum via the IRS filings, and it is likely that the execs will be extradited (Italy will honour US extradition requests, as will almost all of the EU) to stand trial personally, and all assets in the USA and EU will be examined as to reparations. Strongly would suggest they settle, and pay up for the rights, and the profit share, because the alternative is to have all the board of the LLC and Inc get measured for non Armani jumpsuits. Yes Armani does do tailored jumpsuits, and even bullet resistant ones.

The likely way he gained access was because the shipping companies often recycle logins for the ERP systems, as they pay a per login fee, so if they have 100 seasonal workers, they will all get given the same login and password, as it will still have a separate terminal ID to use with it, but no extra charge. They will also never change the password, as then they have to train all the seasonal workers again, and manglement will have a hard time remembering to turn over the keyboard, to see the new post it note there with the username and password on it. Thus he just logged in remotely, as if he was a worker, and trawled through the packages looking for the ones he needed, and marked them as undelivered, while in fact they got delivered. Then the "customer" got a refund, and the shipping company got left with a missing parcel, which they could not trace.
Only way was found that likely somebody went and looked at the logs for drivers, saw the log there said delivered with signature, but the ERP system said not delivered, and they started to look through all the missing items, and comparing with the old delivery device logs, and saw the large number of mismatches. Then started looking, and saw a terminal ID, and finally were able to track it down to a residential IP, enough evidence to get a search warrant for the address and all computers, which probably still were logged in, and also which had history of all the transactions screens as well. Will bet that this scam was a lot more than the $3.6 million, but this was what was provable through logs in the ERP, and on the computer.

The tubes shrinking from T12 to T8, and then to T5, was a result of increasing phosphor efficiency. The T12 phosphor was essentially the same phosphor since they were initially developed in the 1920's, and was very limited in operating temperature and allowed light emission. Thus you needed a certain area of phosphor to get a defined light output.
Later improved phosphors allowed both higher light output, and higher operation temperature, and also the smaller diameter tubes allowed a reduction of volume of gas fill, and also a drop in the amount of mercury in them, so the mercury went from almost 100mg for a T12 lamp, to 5mg for T8, and down to under 2mg for a T5 tube. CFL units are at around 0.2mg of mercury per lamp typically, ironically making recovery of the mercury near impossible, as it is so little. The biggest killer of them in enclosed and any fixture is that most of the power dissipation is in the filament ends, where you have to heat up the emitter material, so generating all the heat right by the electronics, and also in a nice insulating plastic enclosure. green PCB at manufacture ends up at EOL as being charred black, along with pretty much the entire inside of the lamp.
Drawback of LED units is that they are also full of large amounts of toxic metals, Gallium, not so bad but still a heavy metal, and Arsenic, part and parcel of the Gallium Arsenide used to make the light emitting diode chips used in there, plus of course the phosphors are pretty much the same ones used in the flourescent lamps, and those are also a witches brew of heavy metal oxides, enclosing the GaAs chip.
Flourescent linear lamps are easy to recycle, mostly glass, a bit of nickel wire, some strontium and tungsten, and a little fill of aluminium and copper from the ends, plus the water soluble phosphor inside, because it is deposited using a water based slurry. Crush up the tubes and wash them, and the wash water has almost all the phosphor and mercury, because it tends to bind with the phosphor (which is why you see so many T5 lamps that are pink, because the tiny amount of mercury in them has been adsorbed onto the phosphor coat strongly), and then you simply use eddy current sorting to pull the metal parts out, and melt them down again, and the glass goes into a furnace to make new ones. CFL units harder to recycle, you have to separate the electronics and the tube, and then mostly just recover the copper and dump the rest, and the same for LED lamps, if recycled only the copper is stripped, all the rest is just more waste to be dumped or buried somewhere.
There was a brief period where CFL units had replaceable glass, as the idea was to reuse the electronic unit ballast and have a simple east to replace light emitter, but the integrated CFL quickly killed that as they were cheaper to make. Still have a few of those units around, and they will outlast the LED units very likely, as I also have a good supply of the PL flourescent lamps they use.

The remaining pieces can still have use, as a set of shelves under the bench, to hold things like power bricks, and outlets for stuff always plugged in, plus a cheap set of drawers fitted to the one side (on castors so you can easily move it side to side) helps as well with storage of all those things you need.
With the IPA a good thing is to get small HDPE bottles, and put small volumes in it, so it is easier to use, and less likely to spill. Works with flux as well, buying in bulk and refilling the pen, though I simply went and got empty dropper bottles, and filled them with flux, and the same for IPA, using nail polish bottles that hold 10ml each. Easy to use, and much better control of where you apply it. Little brush makes for easy cleaning, and you just rinse out the bottle when it is dirty, or move it to being the first wash bottle, and have a clean final wash one.

Easiest thing for the floor is to simply rent a buffer, and clean it using the rotary brush attachment, water and detergent in the mix tank, followed by a rinse, then simply use a commercial liquid polish to seal it, probably 3 coats applied with a flat mop. Will seal the concrete from spills and stains, and will at least keep the dust down, plus easy to patch as all you do is strip with polish stripper, wash, let dry and then apply another coat. Do every year as a maintenance task, and it will still allow you to have bare concrete look, but a little more resistant. Downside is if you want to do epoxy afterwards you will have to diamond grind off a millimetre more of the surface to get to bare substrate, so add an hour or two to the epoxy job.

Carbon deposits are from both too long between oil changes, and from not allowing the turbo to spin down before shutting the engine off. Long oil change intervals allow the oil to form sludge, which, combined with the turbo spin down with no oil generating enough heat to degrade the oil, blowing the breakdown products into the piping. The return line is larger, so the restriction will be less noticed, but the supply pipe is small diameter to regulate the oil flow into the turbo, so it will clog first.
Solution is to change the oil at the "harsh service" intervals, as noted in the owners manual, as the only way to get the oil to survive the regular service interval is to drive the vehicle like the "old granny driving for a Sunday country drive, and enjoying the view at minimum speed limit" all the time. If you are driving to enjoy the acceleration change oil more regularly, it is a lot cheaper than the 2 turbos.

@paulhaynes8045 The phone has GPS yes, but also the towers, because they have a fixed nearby location, also will send the ephemeris data for all the locally visible satellites to the phone on request, so the phone GPS can lock really fast, and it also uses the time difference between local towers to gat a very fast and somewhat accurate location if indoors, so that it can at least give a position to within 30m almost immediately, even if there is no sight of the sky for GPS signals. The GPS signal is used outside in your car, to track better, but rough location is done using the signal strength and timing of local towers.
Did once turn on a phone GPS with no coverage from the network, and it took around 20 minutes to finally position me, within a 100m sphere, while another phone, with service and data, took under a minute to position, using data and the 2 visible towers to get a rough area to gain coarse position fast. GPS in your phone needs data, stand alone GPS can do without it, though your accuracy improves with time on, as it refines errors out long term, though you also get the map used providing some sort of sanity check, as there is an assumption if you are moving you are on a road, allowing it to remove parallel paths easily.

Years ago company had a check, already processed, get processed again for another, smaller amount. Do not know how the fraudsters got the check, seeing as the company normally got them back, verified against the book and computer, and then they get shredded. We did not get that one back, as it had only been done a month ago. When it arrived for the second transaction, it had been washed, stripping all the info and background, leaving only the MICR ink, and the signature. The rest had been reprinted, using an inkjet printer, including the background and the printing, and the check had been changed from account payee only to cash, and cashed at another bank. I could see it was reprinted, inkjet dots visible and the dithering, and the spots of cyan and magenta used to change the yellow slightly, plus the fraudsters used the wrong check printer (this bank uses 2, and only one in my city does these for them) in the side margin.
Luckily the book of business checks also had a check made out in error, and this cancelled one was sent with to prove that this was fraud, only a few numbers off, and also an example of how they should look. Bank ate the cost, but of course the police never investigated, a part of the reason checks were stopped as legal tender a few years ago, as the banks reported over 60% of them, including ones printed by the government and Internal revenue, were either fraudulently altered, or were fake, or were refused due to insufficient funds.

If it went to trial the waypoint could be placed within 150m of a border, and still fall within the error of the GPS, as the non military use of GPS is only guaranteed to be accurate within 150m of the true location, provided the GPS unit is stationary for at least 10 minutes, as a moving GPS can easily be up to 300m/1000 feet, out of true position, and still be classed as being within specification, while still showing a valid position. Also if it had just been turned on from sleep, keeping a rough memory of position, so it does not have to sit and run through all the codes to get an accurate position from multiple satellites, it can still give a rough position, and an accurate clock and date, with only getting info from 6 satellites, but more and more visible ones provide better ability to triangulate an accurate position. In a forest with trees blocking view of the sky it can be hard to get reliable position, and waypoints can easily be out of the correct position, but close enough to see the right position.

FBI comms van, acting as both a local cellular tower to improve bandwidth, and also acting to allow all the local agencies to communicate with their government issue phones, so they can share info, and talk using the PTT function that you can get with the right phone firmware on the phone. Also likely acting as an IMSI catcher for the area, so the ship crew can communicate with shore as well, allowing the assorted crews to get long battery life, as the phones do not have to communicate over a mile or three of water.
The drone interdiction is very simple, the idiots flying them get too close, and can get into the crane cables, or hit cables or crews. They simply will be using a scanner to cover the ISM bands the drones communicate on, and when they get a signal approaching they simply look and try to read the federally mandated ID on the drone, and the federally mandated ADSB transponder on the drone, and if they come back there will be a few agents visiting the registered owner for a not so friendly chat. The NTSB drones are registered, so can fly no problem. Generator on trailer there because the on van generator, built into the side, has only around 5 hours of fuel capacity, so the external generator, massively overkill currently, has around a week of fuel in it's tanks, and can supply enough power, in addition to the van use, to run a mobile HQ that has lighting, computers, AC and such in it, in a few extra vans that are not here.

Jaws look like cut sections of extruded aluminium, no casting, just make a die and a foundry will make you 600kg of them as an order.
As to the clamps for the stone, use the PTFE and machine them out of it, or at least make the pivot point out of some, less jitter in the operation. For the holes, adjustable reamer, so long as you can get through hole you can get the clearance to exactly what you need, very useful if you have a shaft you had to cut undersize, and new bushings that come in over thickness that you need to get the right clearance after pressing them in.
For a better look than PTFE use Vesconite Hilube, with a pattern in it that looks like grey marble. Also works well with water as lubricant, or nothing at all.

Russia can simply lease aircraft from the rest of the BRICS, who will then simply pay for the maintenance, with the aircraft doing a lot more flight hours than normal. Spares wise yes they will suffer, but there are still plenty of countries and organisations that will, for a nice big fat fee, arrange for new parts to travel via some intermediaries there. Sanctions yes, but you will find Airbus and Boeing will plead innocance as to these intermediaries buyin from them, often as added orders for existing airlines, and the excess parts eventually landing up in the russian side.
Bigger problem for the Russian planes is that a lot of the avionics and advanced technology came from Ukraine, there is a lot of high tech manufacturing there, and now they are definitely not going to supply the parts the Russians need, which often are small critical parts where getting alternate vendors is near impossible.

Sadly the LED lamps are now built to last just as long as the ones made by the Phoebus cartel, and they are designed so that they will fail after around 1000 hours in use. done by using components right on the edge, and also by driving them as hard as possible. The same parts can be made to last nearly forever, just by derating them, so that is why you now have the Dubai lamp, designed by the outset to at least last 100k hours in use, and to be more efficient at the same time. But only sold in Dubai, as they were mandated by the king, and the manufacturer, Phillips, does not want to sell them anywhere else, as it will kill the market for them worldwide.

Been using low cost phones always, they are good for my use, and are suprisingly durable as well. Only time I upgrade is a year or so after EOL, when I look for something equally low cost, which, when I got the last phone, was more mid range than the one I bought, but now, with volume production, and increasing integration, it is now classed as low end.

Yes had an industrial one. Used 44 gallons of tricholethane, and would clean things in seconds. We used it to clean PCB's, and that was a fine balancing act between stripping off flux residue, 2 seconds, and stripping off the conformal coating, ranged from 5 seconds to never, depending on the exact conformal coat used, of which there were 3. Leave a board in for 10 minutes and the resin bonding the actual fibreglass weave together left, which was useful for some boards, where we were robbing parts off them, and did not care for the actual board itself, though it did a number on component markings, so they were all labelled again afterwards to identify.. Hot solvent was also great to remove potting compound from the high voltage assemblies, it took around 1 minute cycle to soften the surface, and then you could pick out the soft resin without damage. When finished pot the assembly again to keep it from arcing over.
Friend would bring stuff over for cleaning, though I told him when to bring dirty things, like carburettors, valve assemblies and such, when it was getting time to replace the fluid due to it being too dirty. Then all those went through in an hour, and then dump the hot dirty fluid into a drum for disposal, and fill with clean new fluid. Carburettor, put in black with dirt, and it comes out looking like it just came out of the casting mould.

Why do you need so many rockets? Simple, making big rocket engines is hard, and making big rocket engines that are reliable is harder, and making big rocket engines that are reliable, and restartable, is an order of magnitude harder. So you make a smaller engine that is reasonably reliable, that you can be sure will restart, and where the smaller size ensures that you do not get too much instability in response.
Plus you get the ability to have a wide thrust range, because big rocket engines only have 2 thrust settings, off - no thrust, or on, with a small range of adjustment in pressure available. Small engines you can get wider thrust changes without it stopping, though even there you will only have a 10-20% range of control of thrust, but if you have a few you can just use more of them.
That bit of rocket science came from the 1960's, when NASA destroyed a good number of engines and test stands making big ones that did not blow up after 30 seconds. The USSR had an engine that worked, so simply went with the put many approach, as they saw the difficulty of making a big one, and wanted to get something that worked first. That the rest was built from substandard parts was the problem.

That GPS mentioned also relied heavily on having an accurate local map, and also on you having close by, at least within 2km or so, a very well marked survey point whose position is, by dint of the old mapping having placed it correctly a century or so ago, and it being verified as well numerous times since then, so the exact coordinates are known down to the metre. Then a local GPS receiver is placed precisely over the pin, and the survey receiver is also placed an exact known distance and angle away from it, and allowed to measure till the 2 can agree as to local error. Then you use the mobile unit, and it, using a radio link, communicates with the survey repeater, allowing you to calculate any slight drift and transient error as you move around, as it affects both equally, so that after the survey, and you return to the survey point, and again place the mobile unit onto the exact same point. Thus any long term errors are found out, and if the positions do not agree you do them again, to get in the end a very precise map of where the points are relative to the survey point.
Yes you can achieve an accuracy of 0.5cm over say a construction site, which is an order of magnitude better than your old surveys could generally give, due to reading inaccuracy, and over say a field you can get a map that is as good. But all depends on that actual known point, and it not moving at all, and not being shadowed at all during the survey by things like people walking by, or trucks or cranes in the area.
Otherwise regular GPS is only accurate to within 100m on the horizontal plane, and 50m in the vertical, the perceived accuracy comes from the actual map inside, when the processor makes a best guess as to where you are, trying to get you to match the known roadways and tracks entered on there, otherwise it will, if unknown, default to placing you "near" the road, or placing you on "service road", when the actual position does not agree within the 100m distance for locating a road. Fun comes with outdated maps, or new deviations on a road that have not yet been placed in a map, where you might be shown to be in a field for a while, with a rather confused direction algorithm attempting to route you.

Blaster is also very good at cleaning EGR tubes, as it simply has to have the suction attached at one end, probably using some duct tape, and then blast from the other side, so you do not waste the media, and get it Noisse and Shiny as Ray wants.
To blank off parts that do not need it best to use duck tape, and it will hold up well to the media, unlike painters tape. For the media valve simply get a large diameter water valve, exactly like the air line one, and put it a little further down, and use it to turn off the walnut flow. Large diameter valve, also called full bore, so that it does not clog, and probably best to use a ball type over any other as those at least do not clog up easily, while others like butterfly will, and the only one that will work with mud and muck is a pinch type, which closes off the hose by compressing it.

A well known issue withbatteries, the terminal voltage drops with temperature rise. Thus the simpler charge systems interpret this as being a flat battery, or one with a large load on it, and try to keep terminal voltage constant. This then charges the battery even more leading to heat being generated in the battery, and a loss of electrolyte from both chemical reactions and boiling off. Most modern aircraft will have both thermal control of the charge voltage, and as well a thermal switch on the battery that indicates a hot battery.
Being such an old design this was likely not on the Tupelov, and instead they had the old fashioned starter generator on the engine, where it is quite capable of charging the battery at a very high current if needs be, equal to the starting current draw of the engine. One cell would have shorted out, either from flaked off material bridging out the bottom of the cell, or a separator failing. This then self discharged the cell, and the terminal voltage of this one cell dropped. Then the engine voltage regulator simply tried to keep battery voltage constant, overcharging the other cells, and the battery got hot enough that the cell separators melted, and shorted out the battery totally. Not an easy thing to recover from, as the generator can be disconnected in flight and the battery can temporarily can provide the full load, but the battery will discharge very fast. You cannot really disconnect the battery from the DC bus though, at least not in flight, there are isolating breakers and fuses inside the avionics bays, but you would need to open panels outside to get to them.
They were very lucky though, old design, mostly mechanical linkages and hydraulics, and no electrical systems on the engines needed to run them once started, and the important EGT gauges are self powered by the engine exhaust heat. More modern engine no electrical power no engines, all is controlled by electric motors and valves.

Helicoils work well putting direct into aluminium castings, as this gives a bigger grip area to the casting, but the bolt you use can be one size smaller, for the same holding force, as the insert spreads the load out over the casting evenly. Plus for things removed frequently they mean no hole wear, and if it does eventually wear out, you just pull out the insert and put in another. Even works on plastic as well for stripped threads, giving a better thread to use, though there you do not want the threadlocker as that will weaken the plastic, though you can put a drop of acrylic glue in place of it as you go in with the insert, to weld it to the walls better. Then leave for 12 hours to set up, before putting the bolt in, as it might otherwise stick bolt to insert. There are more insert types for steel as well, including solid ones that go in the same way as a helicoil, but which are machined out of a solid piece of steel. Getting the full set is kind of expensive though, I have simply gotten the inserts and taps, using the next size down inserter tool instead to put them in, and then snap off the tang. Plus bought old US standard sets that had not been moving since the 1970's, when metrication occurred, because they were on sale for the 1970's prices still. Those came with actual metal cases, so of course I also got extra inserts and taps as I needed them. Means I can actually repair a 1/4UNC thread, instead of make it M6.

US engines are typically much higher power output, so the oil is run harder. Note this is a 3.3 l engine, when the corresponding model in the EU area would be a 2.0l engine, in the same block. so the US engine has higher power output compared to the EU block ,and also has much more severe operating conditions, because of long distances traveled every day, and because of this and lots of short drives, because in the USA you drive to the local stores, while the rest of the world you either walk 3 minutes, or have a once a week shop habit. Remember in the USA you often have people commuting 4 hours a day, often in stop start traffic, as there is little to no public transit, and thus a vehicle has a cold start, then run foot flat for 2 hours, then from that to off and cool, down, and repeat. Much more aggressive drive style as well, almost binary in pedal position, either foot flat, or hard on the brake, because there is no defensive driving taught, or any sort of care for fuel economy, because USA fuel is cheap. Leads to fuel dilution, high engine loads, and also because of higher internal stress early failures
By me that same Sedona comes with a 2.0l 4 cylinder engine, as there are not many V6 and V8 engines, and also most vehicles have lower power ratings compared to the US model. Yes much lower power, but they then again also last a lot longer as well.

@lasskinn474 They buy the bad debt, expecting to collect on it, but then in turn, once collected on, they sell it in turn down again, making more money off the payers. After all, till the person fully pays it off, it still exists on the book as debt, and can be sold on, even after the person has fully paid it off. So you can literally have 15 judgements against you, all for the same original debt, and all want to be paid the same amount plus fees.

@StringerNews1 Yes true, the tanker that comes to fill up is owned by the refinery, or a contractor that does deliveries, so all the stations on the route get exactly the same fuel, as there is generally only 3 internal tanks in the trailer, with each having the possibility to hold a different fuel, but all have a gate valve at the bottom of the tank, that leads to a common manifold and a meter, so that when filling the customer (the fuel station) is billed for the volume of fuel. Might be filled all with one grade of fuel, or a different one in each tank, but the area filling stations all get the same fuel delivered to them.
By me that would be either 95 unleaded fuel, or regular diesel, or low sulphur diesel. Some tankers have 5 tanks, so also will have a small tank that is used for illuminating paraffin, which is often illegally blended with diesel as it is cheaper, as a lot of filling stations also sell it as a heating and cooking fuel, alongside LPG.

@StringerNews1 Pipelines it is easy, you have an inline density meter, that is measuring the density of the fluid. You change at the sending end, and the receiver simply waits till the density starts to change, and switches tanks. A few thousand litres of different fuel in a 100kl tank is barely going to be noticed at all.
Refineries are owned by a oil company, but sell to all in the area irrespective of brand, and the base fuel they supply is the same. No fuel station puts in additives any more, just sells the same base stock in different grades only. They will sell it retail, as that way is a lot more profit, for what is basically a blend of paint thinner, turps substitute and some extra solvent, with a dye to colour it, in a fancy bottle.

So what is new for Range Rover then? BIL had his own parking spot in the service bay, and as I dropped it off there so often the security and most of the sales people thought I actually worked at the dealership. I used to skip the check in line, drive through the side entrance, past the security then take it to it's parking, and leave the key with the service office, along with the fault list for the week. In the months they had it that recall was out for "immediate attention", and they had the new pipes, but they were never installed.
Guess how we found that out, I was driving the kids, and the hose popped, so I had to do a roadside fix to get it going, using a multitool, and cooldrink to fill the water up. Yup popped head gasket on a rear cylinder, but it was "within specs", so it had rough idle when cold forever after. The low water sensor is disabled on start, as it would otherwise falsely trigger with normal coolant flow.

Bulk buys, meant to stop price matching. You have to find the exact same SKU elsewhere, for a lower price, to get the price match. Well, if the shop has a unique SKU just for them, then no other retailer, even if they have the exact same brand, package and product, can have the same SKU and UPC on it, so no way for them to have to worry about price matching and losing money on the sale. A sneaky way to be able to have big blurb about "price match any other, and give it cheaper" while knowing they will never actually be called out on the item to honour the match.

Billing errors my father signed up for direct debit of his municipal bill. After around 3 months they mistyped the amount, and instead of taking around $36.00, they took $3600.00, slapping his cheque account into the red. He saw it the next day, as the bank called him (the good old days, when banks actually knew their customers, plus at that time he had been a customer of the bank for well over a half century) about this.
So he went down to the municipal offices, armed with the statement, and the bank fee schedule, and his bill, and went up to the head of billing to get this fixed. They wanted to give a credit to the account (over 100 months, basically a decade) but he told them that he was going to sit in the head of billing's office, all night if needs be, till they had both rectified the mistake, paid him for the overdraft fees and interest charges (thus the rate schedule), plus issued him a letter to the bank about the error, and cancelled the direct debit. He got all 3, though the kicker was that, due to having banked with Barclays PLC, in various guises and countries, for more than that half century, and being a pensioner, they actually had waived all charges on his accounts for a good number of years, as he was already a pensioner. Then for the next year he wrote them a cheque, dated for the last day he could pay, and put it in the post, with their reply prepaid envelope.
Sadly you can no longer do this. No more cheques, no more reliable post office, no more post boxes on every corner, and I pay mine electronically, a day or so after it pops in my email inbox, as otherwise waiting for the paper invoice means you only get it after the cut off date for the previous month.

Know of 2 dealerships that did this. One was dealing in luxury cars, and skipped with a few million in customer monies, leaving his salespeople and partners to hold the baby. The other was doing regular vehicles, but did the same, skipping 6 months after opening, leaving all the remains and bills behind.
First one skipped the country, and the rest took around 4 years to make the customers whole, and the second the same. Both have cases against them, though the first one some of the customers are still looking for the skipped owner, dead or alive. Second one similar, though they want him alive, though that status is likely to change shortly after delivery.

@thisismagacountry1318 I signed the authorisation form for the insurance once. The only time they would actually send that form in was if you actually crashed in the aircraft and died. Otherwise not worth the paperwork, just any new base you got to fill in the form once for filing. The insurance was 50c, once off, merely paperwork, as the state actually guaranteed the payout. Only once I was worried about the form, when I was leaning out the door, holding the belt of the FE and acting as both audio relay and safety harness for him. Best landing though in that aircraft type, slightly marred by the 20 ton fire engine keeping pace with us next to the runway, with a foam cannon armed and ready. But we did have to land, wheels down or not, seeing as the fuel was down to zero.

Bitcoin is just anonymous, but, due to it's design, it is absolutely, and totally designed to be traceable in full, all the way from the first generation of the coin, to every transaction it has ever been associated with, and this is going to be fixed in forever in the bitcoin blockchain, and totally unable to be removed, changed or obscured, and this is the only way that trust in the coin is going to be carried forward.. Plus no need to look at any location, just look in any wallet, which carries as part of the wallet a record of every single transaction ever done up to the last time the wallet was updated.

Yes, I have installed a few of them, because it was easier to do so, but yes I prefer the LED lamp. However the LED drop in flourescent tube retrofit is a great item, well worth it to get. Incidentally I also have some very early implementations of the CFFL lamp, a base you put in, that then takes a PL lamp in the top, so you can replace the lamp when it fails. They were perfect in 24/7/365 application for over a decade, only needing new lamps every 5 years or so, mostly because they also were good quality EU made lamps, and also because they were run base down, so there was no real heat into the magnetic ballast.
At the other extreme I also have a number of lamps that date from that Phoebus cartel, NOS, with the same spindly single wire filament, both in carbon filament, and tungsten or tantalum filament. Clear and frosted ones, in general dating from before 1939. They are really nice as mood lighting, though with power ratings in candlepower, 16 and 32, or 40 and 60W rough equivalent, they are not exactly stellar in light output, but definitely give that incandescent colour.
Did try running a few on higher voltage, they work up to 340VAC, when brought up slowly over a few seconds, which is something no CFL or LED will do, they all will pretty much blow up at around 270VAC input, either with a bang, or just a small pop. At 340VAC they are insanely bright though, likely with a lifetime measurable in minutes, like your regular photoflood lamps had.

Incidentally I used to travel by bus, as it was cheaper than driving, and paying for parking. One time I decided to not catch a particular bus, and wait for the next one (probably a whole minute extra), mostly because I heard his music coming 2km away.
The heady days when the bus fare was equivalent to 3c USA on the municipal bus line, and 4c on the private one. Municipal one I got funny looks when boarding, mostly because I was travelling on what had been, till a year or two before, a bus that was segregated, and the bus driver was unsure if I actually wanted to travel on the Umlazi bus, instead of the other, much more expensive (8c) one. Common route for 15km, and I was getting off at 14km mark.

The actual flex part is actually a flexible printed circuit board, which is very cheap, and which is generally quite robust in use. They normally get small cracks in the copper foil that forms the tracks on them, often in the middle of the flex, and, unless you clean off all the scmoo that is there to act as a lubricant, and also as a damper for vibration of the flex boards, so they do not vibrate and rub against each other, you will not see the break. You have to clean it off, then hold up against a strong light, and hope that the traces on both sides of the board broke in the same place, as there is a base plastic film, and each side has an etched set of wide copper traces, often overlapping, so the board is opaque, and then each is covered with another polyamide film, and laminated in a high pressure high temperature press to cure the laminates, then punched out of the film, or cut out with a CNC cutter.
The ends will be fixed using insulation displacement connections, pressed through the film, and are arranged so they make good contact, then the ends are often sealed in with a little epoxy applied there, or a plastic clip on cheaper models, or even soldered on some. Ends break as well, especially where the flex and rigid parts are, another place to check, but with the ones epoxied in nothing you can do to fix. Break in the middle you can often scrape the outside insulation away, and solder some thin copper film to bridge the gap, then coat with clear nail varnish as a temporary fix, as it will be stiffer, and break again near there.
Yes replace is best, as often the breaks are such that the horn only works in particular angles of the wheel, and same for radio, while the airbag has the red bag lit all the time, as it periodically checks the airbag for continuity, and detects the open wiring. Very rare do you get shorted wires, though if the outer insulation wears off on high use vehicles (think a taxi that does a thousand turns an hour, in a dense city centre, and which has worn out a few steering racks already) you can get that, though pretty much all of the designs separate the horn wiring from being on adjacent locations to the SRS wires, which are normally duplicated on 2 or more parallel windings, and also are spaced on the film, so there are no wires, adjacent on others, that will ever be able to touch them and accidentally provide a trigger voltage. At least 2 layers of insulation have to fail, before they make copper to copper contact.

Did it the wrong way, there was a case a few years ago of a person who used a valid bank routing code and account for all of his bills. The bank routing code he used was for the local taxman, and the only way he was actually discovered was totally by accident. An investigator for the tax office was looking for another deposit on the main account, and just so saw this deduction occur right below the one he wanted to see. He was puzzled, as the tax office does not normally have that particular transaction come off, as they normally are excepted as another government department, so, after he was done, he went and enquired with the other department, as to why.
Turns out the person paid for a lot of things using this method, including, but not limited to, being his cars, house and all direct debits off for all sorts of things. He had to, after the trial, both pay it all back, lost all his assets, and spent time in jail as well.

@BillyWillicker I worked on avionics where the cover screws, and any threaded parts going into the aluminium main castings, were all equipped with helicoils from the factory. 100 M4 inserts per unit, just for the 2 covers. Electric screwdriver was the first tool I bought, though I did make my own driver, using a long hex wrench with the angle cut off, and brazed into a brass hex spacer that was 1/4in across flats, and fitted the screwdriver. Long, as I knew i would have wear, so a quick grind of the worn end made it new again. Did have to replace the gearbox in the driver, the new Black and Decker gearset was powdered metal, instead of the plastic of the original, and lasted a long time, inserted with lots of light grease to help, unlike the original.

Thing is the huge factory might not be good for the town long term. Short term lots of people there to build it, and a sudden sharp rise in prices for houses, and lots of demand for things, but after 2 years the factory is built, the road to the factory is wider, and the factory has it's own housing on site for the workers, who are not local. Now the town has higher rates bills, the roads are now going to have to have the loans paid for for the next 20 years, and people in the town are actually poorer off. Factory profits do not come locally, they all go out to a head office, and there is nothing other than a little rates income from the factory, while the township has the infrastructure to maintain, with little return from it.

Not necessarily that the parachute will fail to operate, it could, because of the Russian space program wanting simplicity and robustness, have a very simple pressure capsule that was only armed by a pin being pulled during separation, that now is waiting for the pressure to approach a part atmosphere, which would be the opening pressure in the upper Venusian atmosphere, and thus acting as a backup for the electronic trigger, or it also acts to power up the lander, as it would assume it was doing reentry, and thus connect the internal batteries to the electronics. 50 years and the batteries might have still some residual charge, enough to have it give a final few seconds of swansong, as the radio transmitter operates for a few moments before they deplete completely.

That bushing looks like it was made from polyurethane. Cheap urethane will disintegrate with time alone. Had one that went, and, rather than replace it with the same junky urethane, I decided instead to make a new one out of some scrap rubber belting. 3 small strips, held together with 3 small nails used as rivets, and it was a "never bother with you again" fix.
Did later have to replace the motor, it decided to burn out, running around 6 hours a day, after another year of abuse. But I had a spare motor, only lightly used, from having to replace the previous pump because of that exact coupling failing. So put it in, same coupling half, with the same rubber coupler, and it ran till the machine was sold off. Coupler used to keep the pump from having axial thrust, because a vane pump has bugger all tolerance of end float, and will eat up an end of the rotor and the end plate. Less than a thou of clearance is the difference between work and does not grind into mush, and not pump at all, with the oil film providing the seal. Yes those pumps did not live a merry life.

Military with drums of fuel always left around 30l at the bottom, because of the chance of water contamination. So those drums always came back to depot, where they got properly emptied, and then refilled. Friend was doing that run one week, and found out he could not fill the truck at the depot, refused as the bill was unpaid. So took down a drum with the crane, and emptied all that ullage from other drums till it was full, and lifted it back up till it was back in position, above the fuel cap. Then hose into it, and siphon onto the tar till it was running jet fuel, then filled the tank. Hose was the depot watering hose, not fuel rated. But that truck ran very well on the jet fuel, lots more power and pep, before you rowed the box at any incline, now it did not need any gear changes at all, and easily kept to the speed limit.

Freezer on the bottom you have a smaller freezer compartment, as it has lost volume to the space for the compressor. As well the insulation there is thinner, to minimise the lost volume, plus it has a lot of hot piping running through thin sections of the insulated wall near the inside, along with 200W of heat from the compressor itself when running.
Chest freezers have the luxury of having thicker walls, so there is more insulation, while a fridge freezer upright combination has thinner insulation, and the door also has to have a heater in the inner wall, so that the seal does not freeze onto the case. Larger length of seal area, thus more heat input to keep it not frozen. Seals also lose heat to convection, long vertical strips of airflow allowing heat inside the box, while the chest freezer has almost no convection along the seal in most cases.
As well the limiting factor in modern fridge freezer lifetime is not the compressor, those will easily, even for the cheapest ones you find in modern fridges, with cost cutting applied everywhere in manufacture, last 10 years running all the time, provided there are no leaks in the gas system. Sadly that is the killer, the foamed in insulation is done with isocyanate 2 part foam, and as a side effect of the cure they do release acid slightly. This will eventually cause the evaporator pipes, and the condenser pipes, to corrode through from the outside.
Most pronounced at the regions of the piping where they are cold enough to condense water from the air in the evaporator, thus at the cold side where the pipe enters, and for the condenser at the hot side, right by the door, where the hot gas is used to keep the seal from freezing in place, and which cools down from heat transfer to the inner side fast when the compressor stops. This then corrodes the steel pipe, used instead of more durable copper, as it is a lot cheaper, and when a small pinhole eventually does corrode through the pipes you are unable to repair it, as the pipes are all buried in the foam, and removal is going to require destruction of either the inner plastic moulding, or the exterior steel skin to expose them, and then you cannot replace the foam easily after replacing the pipes. Look at your modern fridge with a thermal camera and you see where the pipes run, and how haphazardly they are installed before the foam is injected.
With refrigerator freezers the fans in the more expensive models also run all the time to circulate the air, and generally fail fast, as they are run in a very harsh environment, with water droplets running through them in the fridge side, and ice in the freezer side. Defrost in the fridge and freezer is done with a heater element by the coils, so that frost is heated up and melted back to liquid, and this then travels down a heated tube to the top of the compressor, where it collects in a pan, and the heat of the compressor evaporates it. Cheap units the heater runs when the compressor does not, but is low power, around 10W to 30W, so does not put much heat in the cavity.
When you buy commercial units your efficiency takes a dive though, as convenience in getting stuff in and out, along with having either glass doors with heaters so they do not mist up, or no doors at all, is the driver. However those you can repair, as they are expected to last 20 years or more in service, unlike a domestic unit.

VW 2l, so every piece of plastic in that engine is already toast, and needs replacing. Oil leaks, so you are in for a lot of seals as well, plus likely water pump as well ,which means head is warped, and valvetrain is worn. Yes drop in a less well used block, complete, preferably one that came as a front chop complete. Will still need a lot of plastic parts, but will give you the missing parts, the missing bolts and the connectors that broke as well.

I have set timing by ear, then checked later on with a timing light, and it was pretty close, so it never got adjusted, as it was close enough to correct, and within the timing error. New distributor, or rather new to me, because the original distributor got stolen in the street. Toyota engine, and that is a very expensive distributor, and was also only available as parts, and half out of stock. New was close to $400, used one, from a rolled vehicle, was only $25, and came complete with the plug leads, clamp, vacuum lines and the bolt.

@kapa1611 Once he sells a few trucks the bus will be a natural evolution, as it is just a car with the AI and a lot bigger battery pack on it. The Tesla motor units are strong and powerful enough to, with minor changes to the reduction gearing, move a 10 ton bus around easily, as it basically is going to be 3 cars worth of battery pack. Plus supercharge at every terminus, with an automatic connector and AI to align the vehicle in a defined spot, and another AI with vision to attach, and in the 5-10 minutes you are at a stop you can get a decent charge on the unit. Buses rarely do more than 400km in an inner city route a day, and if you are doing a loop around to a suburban hub you can simply spend 15 minutes there to get a charge boost to cover going 800km a day. Battery life will be shorter, but still long enough, and the old ones can easily get recycled or converted to static use.

I buy dry detergent powder, and use a quarter of the "recommended dose" in each wash. For most washing all you need actually is just the water and agitation, the detergent is there merely to allow non water soluble stains to come out, and to hold them in suspension. Too much just leaves a deposit of detergent in the machine and clothes.
You can buy in Japan Sharp made washing machines, that do not need any detergent, as they use water and ultrasonic systems to clean the clothes and get stains out, with no soaps involved. But not really sold outside Japan, where the market is there for a machine that is small, and needs nothing other than water and power to do laundry.
For really stained clothing I do a long cycle, and the pre wash cleaner I add is Coca Cola, a full 2l bottle, as that does remove stains very well, from the high acid content and the sugar keeping the removed stains in suspension. Removes oil stains quite well.

Have been in a barrel roll, in a helicopter, and can agree that it is a low G manoeuvre, as I was sitting there, looking out the open door, with my legs outside, and looking down below my feet at the sky, and up overhead to the ocean. Very frustrated pair of pilots and the flight engineer, who had just spent the last 3 hours baking in the cockpit, with engines running, but zero collective, doing a compass swing and alignment, after replacement of the gyro compass magnetic pick up in the tail. I had been the human intercom between the poor guy being cooked in the tail, and the flight engineer, relaying from the pilots the readings on the 3 axis data displays for magnetic azimuth. At least we did not have to stop, like the last day, because one of the 2 gyro assemblies had dropped out, with a barberpole on the display, just near the end.
Also the 707 had really good cross wing landing performance, I had a front row seat to that, with a perfect near textbook landing, while the 2 C130's that went before scrubbed all tyres to nothing on the landing, and did a really hard landing, which was audible inside the cabin of the 707. you could not feel anything, till the reverse thrust was applied full, and the pilot announced, that for all those interested, on open mic, that we had landed 10 seconds before. too bad my instructor was on one of those 2 planes, and had thought us 12 last ones were flying on a C47, we got put on the tanker instead. C47 was there to deliver AOG parts, and had spent the night as well.

Keep the receipt and box for the warranty claim. If it dies before the warranty ends simply return as defective, get a refund ( gift card is fine, and actually preferred) and go buy a new one with it, as that gives you the same warranty again. I got 7 years out of a cheap kettle that way, even though the actual units only lasted between 9 to 11 months before they went bang. first one was repaired, and died again before the 3 month repair warranty expired, and they simply gave a gift voucher, which gave a new unit, and a valid 1 year warranty on it, which, with a copy, went into the box, along with the loaner kettle. Kettle no 8 lasted 1 year 1 week before it died. Those 7 replacements cost me only $1, as the price went up in year 5, and the original store had closed up the branch.
Just had a TV fixed under warranty, as it had a failed backlight, just 4 weeks short of the 3 year warranty expiring. The year after I got it, they had changed to a 1 year warranty, for some reason.

@WrenchingWithKenny Best luck for that, if I was in the USA you would be my mechanic, but being your own mechanic does mean I do most of my own servicing, plus I know a good shop for those that need special work. Of course I did see a nice '07 Cadillac in there, and I did do some free help with the owner on it, because you very rarely see a '07 Cadillac with mostly all original parts, mostly because the 1907 was more than half wood. Also a lot of MG cars, and those are nice, even though I cannot fit in them easily, but they are fast, even when you drive slow, because of that low and open body.

State mandated, but the casino has some room to play with them on the fly, just has to be the state mandated amount on audit. Random number generators are almost all PRNG in software, though the seed for the generator is very long, and the machines are left on 24/7 in the most case, so the chance of getting the sequence are very low, though there have been a few cases where they were cracked, but again, long on time, and clocks that are going to drift, with the PRNG not being synchronised with NTP, which the machine uses for logging, so that the drift is not easy to determine.
Also the random number generators use the random things like yey presses and screen touches as part of the salt for the PRNG, and generally, because draw is so small, have a very large pool to draw from.

Incidentally almost no plating plant can ever move, as they will have to rehabilitate the old plant, and about the only way to do that is by digging it out down to around 5m, and sending all that soil and building to a toxic landfill, and then bringing in new fill material there. Still going to have contaminated dirt under there, but it will be far enough down that, providing nobody in a large radius has a well, it will not be harmful.
Not only the chrome itself is harmful, also the under plates are either toxic or harmful, as to plate chrome you first need to polish the steel or whatever to a mirror finish first, then plate it with a layer of copper as a bonding layer, then follow that with another polish step, then a nickel plating step to get a smooth hard surface that will accept the chrome, then finally apply the chrome plate on top, and finish with a final buff to polish it.Even for plastic the plating is the same, just you first start with putting a thin film of some conductive material on the plastic, generally a graphite spray, or vacuum depositing a thin copper film on it, or India ink applied to the surface in a thin layer, to make it somewhat conductive. Then apply the copper underlay, and plate up from there. Multiple steps, needing both harsh acids and detergents to strip the films and clean the parts, then lots of pure water for washing.

Many of those companies also use a POX for mail, so that they can simply toss out the notices that are there about the signature being needed, or toss those that arrive in there, so they can deny getting the cancellation request. The only way to get a signature would be to pay a server to serve them in small claims court, for a few months of membership fees, with the returned mail as proof that it was sent and ignored. Having to either have a lawyer local to you, or the gym manager, spend all his days in a court trying to say that he was not informed, will likely result in a few default judgements against them, and the gym forever having the equipment taken and auctioned off as well. Funny how in other lesser countries this type of cancellation is considered a predatory practise, and is illegal

Probably, otherwise they are sitting on stock, that they could potentially make a good profit on, especially if they also finance it, and get that interest in as operational cash, along with the initial sum, only taking the risk long term on the purchase price. Good money if sales and repayments are good, and they can roll the purchase price out with a low interest loan to them from a bank as cover, and charge a higher rate otherwise. Dealerships hate stock sitting, especially if they have paid for it already, which is why you see so many with a full lot of vehicles all there "on consignment" in that the dealership is not actually the owner till they are sold, and only then briefly for a day to do the transfer.
Can bite though, there have been a good number who did the on consignment thing, sold the lot and vanished with the money. Was one near me, the owner did the runner, leaving the salespeople holding the baby. They survived and kept running, under a new name, but also have put out feelers for him and family, with a reward for dead or alive.

Or just contaminated gun, because the shop does not pay for 3 rinses in the gun before you change paint. Dump out the little bit of left over, wipe with a not solid yet rag, then a rinse with a tablespoon or two of solvent, then the next one goes in. Yes might be bubbles because the clearcoat ran out, but also probably old flakes of other paint that peeled off finally. Also a rant about body shops, modern paints can go on and be gloss straight off, why does every paint shop put it on to a matt finish, then buff the hell out of it. First time I ever used a spray gun with epoxy based paints I only had a slight matt finish on the first coat of primer, and the second coat was dull, because i used a fast thinner on it. Then the main coat i used a retarding thinner for all 2 coats, so that I would not have that. Yes did have a little bit of fisheye to fix, because I was learning just how bad silicone can contaminate, but that was doable with sanding down, and a redo a week later on after it had cured. Then we did a friend's car, where we got both coats done using only 1l of paint, and 2l of retard thinner, we just made it to the end before running completely out of paint. Had a few dust spots, but no booth either, just Saturday afternoon and Sunday morning, under cover as best as possible.

@Galiant2010 Thing is that YT copyright system is broken, anybody can claim they own the copyright on anything, and the video will be taken down during the resolution process. the resolution process is the one who got the notice asking the one who made the claim that it was fair use, or that they do not actually own the copyright, and the universal response is "sue me". plenty of examples of copyright being claimed for literal silence of a few seconds, or somebody claiming copyright of other people's copyright free work. News org runs a news segment containing NASA footage, then sends a copyright claim to all who used the same NASA footage, even if it was directly from NASA. Others claim the captions are theirs, because they have a video that, because it was created by the same open source video editor, they claim the fonts used are theirs, and even the words like "the", "and" are copyrighted by them.

For clothing how about that free drying that a clothes line provides. Pretty much zero running costs, and you definitely have the room to put the lines up, plus an added benefit that your clothes come off the line almost wrinkle free, less of the ironing chore, and for many fabrics no ironing at all, plus longer clothing life. Clothes lines last for decades, with almost zero maintenance costs other than the occasional line replacement, and by me the sun shines all year round as well, so zero operating costs as well. BTW clothes also dry on the line at night, even without the sun, so hang in the evening, and fetch next mid morning all dry, unless it rains.

@TwoBitDaVinci Well, 10 year old black shirts, not the best quality, just cheap ones for work use, are still surviving, they wear out from use before fading much. As well simple to fix, dry inside out, that way no chance of bleaching. Dust is not a problem either, just a shake out gets it off, plus sets the fabric, and you fold it before putting in the laundry basket, so that it is almost ready to put away, and thus no creases. Less wear with a line than a drier, as the drier turns your clothing into a thick layer of felt in the filter while it is running. Just have to buy clothes pegs, preferably bamboo ones, as they do last longer. plus sheets and such are so much nicer after a sun dry, and you can also have rugs washed by hand as well, then hang to dry.
Sold the drier years ago, seeing as it was last used last century...... and only then if the cloth nappies could not be dried in time because of rain.

Also the problem comes with financing, where there is a title holder who is a financial institution on the papers, who has to give clearance before they can transfer title. Some now charge you for this, as an extra fee once you have paid off the vehicle, so they can make an extra few month's payment as a bonus at the end, otherwise you will not get the title, despite having paid it off, so you are unable to sell the vehicle or trade it in without first paying them. Now the vehicle registration to the new owner sits in limbo till this is done, thus the need to have temporary papers for a long time, often with them expiring first, before the finance is settled, and the title is cleared to actually have the vehicle taken by the new buyer legally. Also if there is a loan to buy the vehicle, and the seller did not clear the outstanding, but got the money and did a runner, somebody is going to have to settle, and the hot potato is who exactly is going to be the one, because buyer got a contract, seller is gone, and first financial institute wants money. Only place is from Carvana or the new loan provider, who has to eat this loss, as the new owner bought with the assumption of clear title. Neither wants to pay, so the state is stepping in to tell them to fix this up.

Yes, I do not mind my dentist, he has a great chairside manner, and he works to minimise pain at all steps. Simplest thing he does is put a small amount of the injectable lidocaine onto the gum first at the site, and wait a minute, looking at the rest of your mouth at the same time, then going in, putting a small amount in the now numb area, and then another minute of waiting, then finally the full dose. You feel nothing at all, which helps as I am insensitive to the local, so the regular dose normally means I do feel pain, but it is manageable for the duration.
Fun thing about the 'caines is that they sublimate, or at least that is what they say in the police evidence room, when the amount they show on trial is half the amount registered at the bust.

Banks really do not want your personal accounts, they want business accounts and loan accounts, which make them money. Loans they loan you money, but now you pay them, plus now they also have a loan that they can then use as collateral, and sell on, making the money back. Your interest is then all profit, which is why you see the first part is paying off interest alone, then the capital, so best to pay a little more each month and bring that capital amount down, as you either finish a few years early, or have very reduced payments near the end.

A good number of Uber passengers are clueless, they will get into any vehicle that stops in front of them, provided it is one of those group of vehicles commonly used as an Uber, and confirm where they are going to as well. So easy for the fake to get fares, and drive them to the location, likely close by, and a common location.
I drive a vehicle that is not a common Uber vehicle vehicle (ie not a Toyota Avanza, Hyundai i10, Suzuki Swift, Toyota Aygo, VW Up, Renault Kwid or VW Polo) and still have people attempt to enter the vehicle, if I stop outside popular Uber pick up points. they literally have no clue as to the identity of the vehicle, or the driver, and very often the people get in the wrong uber, or land up at the wrong destination.
Yes people are that clueless, i can well believe they will hand over the phone as well, because a lot of uber drivers rely on spots with free WiFi, so as to avoid the depletion of their data, as that is almost always a prepaid service, and they buy small top up amounts during the day as needed to a great degree, simply because the amount that uber pays is going mostly to the car payments, fuel, insurance and servicing, and a small amount is going to the driver to pay for him as well.

Pretty much every dealership that has EV sales has a charge point or three for them, and yes there is always security there, because cars do get broken into and stolen. However every EV also comes with a charge cable, and if you buy one you likely will have a garage, to put your million plus rand vehicle in, and a standard socket outlet there to plug it in. Overnight charge will work for most use, street side charge really is for you wanting to go long distance, more than the range, where you plug in for 30 minutes to 45 minutes to get to around 70% charge, go have a break, and then carry on for the next 400km of driving.
People who buy an EV normally also only do 100km or less a day, mostly in city traffic, where you recover a lot of the energy in braking back to the battery. No idling engine, and AC will only slowly use charge as well.

I see plenty of vehicles arrive by me, exported from Japan as scrapped vehicles, and they all go through the country on a car transport, and roll across the border, only to come back a week later registered in those countries, and driving on the roads here. Done to avoid paying the high taxes and duties, with the only thing that every 6 months you need to have the paperwork renewed to keep driving in country. These vehicles are not insured here, not able to be claimed from in an accident, as the driver often will simply give an address outside the country, and no way to actually serve them cheaply.
Also the paperwork is easy to do, as they just drive up on a Friday, pass through the open border, and get the new paperwork, plus fill up with fuel that is a lot cheaper, despite being delivered from the same tanker, as the tax is so much lower. One place has 2 garages 100m apart, one does mostly servicing, little fuel sales, except to those who have fuel cards, because they do not work across the border. Both get filled with the same tanker, just the one across the border sells only fuel, and does roaring trade, except it is all cash and debit card, no fuel card sales, because the fuel price is literally half price, compared to the regulated price across the border. Often the paperwork is simply sent via courier, vehicle not needed, so the vehicle never actually leaves the country ever, till it falls apart. Bribes are cheaper than travel for sure.
As to totalled vehicles, yes totalled means different things, in the USA labour is expensive, skilled repair techs even more so, and skilled panel beaters (not panel changers, a easy thing to swap out a panel, and prep it for the painter to do their job) are rare, but elsewhere you get people who think nothing of heating up a bent and mangled panel or chassis, and pulling it back into shape, and then repairing ant damage with new sheet metal perfectly matched to the original. So a car that in the USA had $30k of damage, but was worth perhaps $50k, will be taken, that $30k of repair is done for $10k perhaps, and the vehicle is sold on again with a new title.
Often done with stolen cars as well, they go across borders, get new keys, a nice new valet, possibly new paint, a service, and then are sold as used vehicles, with no history at all. Only time you get problems is if you attempt to take it legally over the border back into the country it was stolen from, where you will find it is impounded, and the new unsuspecting owner now is carless. But the dealer made a profit, and so did the thieves and middlemen.

@kirkellis4329 My father signed up for electronic payment, and after month 3 they entered the number wrongly, inflating his bill by 100 times. He went down to that department, and told them to cancel the direct debit, and also that he would be sleeping there in the office till they had both given him the error back, as they were going to credit his bill, which would have meant he would not pay for the next decade or more, and also he wanted from them the overdraft fee and interest his bank was going to charge, given by the charge rate brochure he took with him. He got both, within 4 hours.
Then simply went and paid once a month, on the day before due, at the supermarket, so that not only did they get it after the close of accounting, but also had to not charge any arrears, as the supermarket receipt date was the valid one, even if it took 7 days for the cheque to clear.
Me I simply do an EFT when it is in, for the exact amount on the bill.

Cable companies cannot make any profit just being dumb conduits, they need the extra money from subscription services and pay per view, as the basic monthly cost does not cover the lines. Of course they also took government money to build out, so all the infrastructure was paid for by taxpayers, yet the profits go to the companies, and are never paid back. They desperately want to get money from internet traffic, but, as they are classed as dumb carriers, and want to also not be responsible for any piracy, they cannot do that, as any filtering they do, or charging for carrying traffic, will loose them that, and they will drown in court costs, as the big pocket in the thousands of cases they will be named in, as enablers, will destroy them.
The town making a cash grab and failing is good, though the monopoly of cable and telcos needs to die, which is slowly happening, as Starlink is eating into the rural market, and this is both the highest maintenance, and the lowest ROI, yet they are mandated by law to cover it. Then next will be the suburbs that are not close in, and where people want choice and speed, then finally urban areas.

Remember every survivor of an ejection does get a tie pin from Martin Baker, as testament to surviving the event. Fun thing is the speed at which it does eject you does compress your spine, so you will only ever eject once, as the second time might kill you. Your legs get pulled in with straps, but your hands are not pulled in, instead you have both hands on either the top ejection pull ring, or the one between your legs. You do though want to pull your legs in before, as there is a rather good chance if you do forget that those straps that pull your legs in to the seat are there, and that they pull your feet in by being attached to the airframe, and pull in while the seat is busy making you 10cm shorter. You have a greater than 50% chance that unprepared your ankles and shins will be broken.
Yes have chatted to pilots that survived landing separate to the plane, and met the one who landed missing large parts of the airframe behind his seat, but still had a working engine (sans afterburner, seeing as the missile hit that), and no parachute or brakes. Him ejecting would have been fatal, he is a little past the design envelope for that particular seat design, and ejecting would mean his head was the canopy breaker. Fighter pilots are in general short and stocky, because the cockpits are designed for short and stocky people. Very uncomfortable for bigger or taller people like me to fit in there.

He survived because the wing roots are right behind him, and thus on impact the nose penetrated the building, and then the wings ripped off at around row 13, meaning the crushed front absorbed most of the impact, and the little section around 11A was protected from both the impact, and the fire, because the front carried on further, along with the rear dropping into a lower floor as the mid section collapsed the building. Looks like the rear again snapped off by the rear bulkhead, so all those passengers forward were in the fire, and none at the back section stayed with the tail. Lucky man, unlike the rest of the passengers and crew, and the people in the medical facility.
But at least easy to get to the CVR and FDR, hopefully they did not lose power with the engines cutting out and the aircraft transitioning to the emergency bare backbone supply from the RAT, which only provides limited flight control hydraulics power, and a limited electrical power supply to the emergency power bus to power a single display, a single flight computer, and a limited set of cockpit instrumentation plus the radios. but the power of the RAT is limited, as you only have this plus the 2 aircraft main batteries to run things, so cabin wise all you get is floor level emergency lighting and the exits partly lit, nothing else at all, aside from the PA system. cockpit the same, just a single display per pilot, and a standby artificial horizon, plus the standby magnetic compass, with limited flight augmentation from the computers other than limiting input excursions to the flight surfaces. Not even hydraulic power to raise landing gear, just the emergency drop handle that will dump them down to mechanically lock.

Funny thing is those are not common by me, the electronic ones, which use a 48V relay, and a resistor to drop the excess voltage, and a diode as rectifier, are common. They use a 12V zener diode to get power for the 555 timer used as control, and, because of ROHS saying no Cadmium containing things, they instead use a photodiode as light sensor. 555 timer drives a transistor or small triac, that shorts out the relay coil, to turn the lamp off.
Then you get the more complex ones that the street lights use, where the entire electronics is contained within a IC package, made from clear epoxy, that has the photodiode, amplifier and signal conditioning inside on the small silicon chip, and then this controls a thyristor that operates a 20A relay on the board. Note they also have to withstand all faults, so have a large MOV device across the mains input, 480VAC rated withstand, so that they will still survive and operate even if the nominal 230VAC mains has a fault and goes to 400VAC instead. Residential ones use a 275VAC MOV as protection, the last time there was a phase loss by me that got very unhappy, and blew the cap off the photocell, practically getting it into orbit. Not really going to protect, just clamping voltage to protect the wiring, and trip a breaker as it fails short.
Incidentally the street lights, for the most part, come with the photocell socket integrated in, as it is cheaper to make all of them the same, and supply instead a special shorting photocell, which has inside it only a 16A fuse and a 480VAC MOV across the output, so that there is still fuse protection when used in group applications, and the MOV clamps lightning strikes on the line down to a level the ballast and starter, or the LED driver for new ones, will probably survive, and, if not, disconnect the fixture. Most common by me are GE, Siemens and Royce Thompson as photocontrols, with Osram and Phillips (branded as Beka) also having a share, depending really on who won the contract for supply for a particular year.
You mostly see Osram or Phillips lamps though, as the most expensive part is the maintenance, and cheap junk lamps fail fast.

Yes buying older semi luxury vehicles you have to remember the spares are still priced at semi luxury prices, not cheap at all. Funny thing is that Audi and VW are essentially the same car in a lot of models, but the spares can differ by up to 50% in price, depending if you ask for the unit using the VW part number, or the Audi part number, both of which appear on the box. Same part, same warranty, but price depends on end use vehicle.
I used to buy VW wiper blades for my Ford, simply because the VW part number was actually cheaper than buying them from the regular spares outlet, and the VW part was a very good quality Bosch wiper blade, much better than the retail version, bat was sold by VW for use on a Golf. But buy the same blade for the equivalent Audi, and the price was nearly double.

Plenty of those that occur, with the recipient bank often not accepting responsibility for the know your customer mistake. The banks will often push you to install the app for the bank, as that way is a lot more secure, though you also have to be aware of the app store letting a imposter app through. So now you will first have to log in, then authorise on the app securely, and then they will either send an OTP to confirm, or require you to use biometrics to authenticate, or for business use they give you a separate code generator to use as second factor.
With me I also have a nice free offering of a virtual card, which gives a valid credit card number, complete with an expiry adjustable to a range of dates, and the CVV number is customisable, so that if you want to pay a dodgy site ( I paid the government this way, dodgy site for sure) they get exactly one chance to do a transaction, and the amount is entered into the virtual card, plus a few cents more, to allow it to go through. Then you simply change the CVV and it will never work again, or you just close the virtual card and get a new one.

There are however many digital computers that are very much single purpose, not being easy to change the programming to use for other purposes. The exception to that was the minuteman missile, where the old computers were given to universities to be used as minicomputers, as they ad enough complexity and programming ability to act as a general purpose computer. I did work on digital computers, which were designed to replace analogue computers, and they were solely able to do that, replacing a old flight control system, navigation system and weapons system with new ones that were nearly a tenth the size, using all TTL logic inside, and able to equal the old one with much better stability, longer life, and much better accuracy, along with the upgrades also adding in a moving map display and HUD, plus much better aiming, and actually being able to hit the target most of the time, pilot training being the drawback for the misses.

Just remember that the big name tool suppliers no longer actually make the tools, they just have a contract with a supplier to make them with the brand on.
Push pin and body pin kits are worth it, even if you buy the kit for one particular part, still cheaper than OEM prices, and the rest will find a use. Jack stands got a few, from the ones I made as apprentice, to the ones my father made up one day for his own use, and even a pair I got on auction, made by some sheet metal worker, and well made. Will add that a jack is not a long term lift, just to get the stands under the vehicle, though we all are guilty of doing just a quick thing with it. Even used the car scissor jack a few times, and it got lubricated the next day, because it was dry.
Good thing as well, a chain block, even if you do not use it to lift things, they can be quite useful with an I beam as a puller for really suck things. Do not forget to always have spare ratchet straps as well.

@sawomirkuczek3214 Slip rings have a very bad problem with shed material, so pretty much all slip ring or commutator designs have to be open frame, so that the conductive dust can be blown out by the cooling fan. Make it sealed and you now have to add in a air path that has a particulate filter in it, which also has to handle high temperatures as well, which adds cost and mass. Inductive exciter is simple, a set of magnetic doughnuts that have a coil wound in the middle, separated by a small distance, so the one can rotate and the other be fixed, and you apply AC to the one, and get AC out the other, same frequency irrespective of the rotor turning or not. big issue is that for generators they apply high voltage AC, as the rotor is wound with lot of turns of thin wire, and a bridge rectifier to make the AC DC ,possibly with a capacitor on there to smooth it, allowing lower rotor loss, and thicker lamination's to be used. Here you need to vary the DC current over a wide range, so need to have fewer turns, and much higher current for the same field strength, so you need low inductance in the rotor coil, and thus the fewer turns, and the higher current means a big beefy bridge rectifier, with it's associated heat dissipation.
My guess the thing that Mahle did was put 3 phase rotary transformer in, run it at a higher frequency, so they can use low cost powdered and sintered ferrite parts, and probably have a 3 phase H bridge running at around 40 kHz to excite the system, and secondary side put in an active bridge rectifier to handle the 50A or so of current flow. Overall cheaper than putting in 50A rated carbon brushes, which will be massive blocks of copper graphite, probably 50mm by 30mm, running on the rotor, and probably still dissipating more power in brush and contact loss than the electronic system as well. Making use of current components the biggest thing will be cooling, to keep the semiconductors cool ,as they are the most sensitive item, so the oil bath will help, simply using aluminium core PCB for the active switches, and then a board on top, fully conformal coated, that is attached using IDC connections, with a top layer being the connections to the ferrite transformer. All running in a thin oil, 0W10 is a common modern one, and you get even thinner oils as well, which pour and act like water. That then can be cooled easily, and the rest of the motor can run in it as well for rotor cooling, with a thermal transfer loop to provide cooling via a water and glycol external cooler, so you can get cabin heat out of the rejected heat as well.

@perhapsbutmaybe Well, tell that to the small towns that put a speed camera exactly one foot in from the regulatory distance from the town boundary, where the road is still the exact same road, and there is still nothing for the next 10 miles, but they changed the limit form 55 to 25, because that is guaranteed to earn them income. They know that, needing to go to the town court to contest, that most will simply pay up, because fighting a $100 speed ticket will cost them at least a 2 day stayover, because you can bet the county court will put them at the end of the day, and will roll them over to the next day, or week, to contest the ticket. Officer will not even be in court, because why sit a day in court, and not be out getting the budget for the month in. Then the police chief will, near end of day, ask for a stay because of "police emergency" AKA out clubbing passing seals/motorists, and get it, then next day will call the officer in early in afternoon to fight it, and have him there to say all about safety and such. Ask how many locals get a ticket and you find out those all got reduced or dropped because they are the ones voting the chief in power.

Yes likely harness has a flat spot in insulation, which rubbed through under the sleeve, and the data lines were shorted together. Moving it away got it to rotate the wires away. Probably best fix would be to unplug the TCM connector, pull out the loom, and check for frayed wires where it was next to the hose, and sleeve them and tape up again, so you can be sure. Any of the CAN wires separate them in that area to see if they were crushed, and any bare copper, or thin insulation, there was your problem. No broken CAN wires though, that would set that CAN was in a degraded mode and you would have a slew of other errors about bus speed being dropped down.

As more satellites were added in different orbits, accuracy improved. With low numbers of satellites, and also with long paths through the air to provide diffraction of the signal, you got poor accuracy. More orbits meant more visible at any time, and thus a more precise position. You need, IIRC, at least 4 to get a coarse position in 3 axes, and with every added satellite visible at the same time your error reduces. At 6 you get 100m, and with more the error reduces further, with most receivers able to handle up to 12 simultaneous decodes at a time, and with more sophisticated receivers using ADC units that can sample at the actual chirp bit rate, timing each individual bit as it comes in, and thus being able to correct for smaller drift with each cycle.
Some of the software defined units have no real limit on the number of satellites they can view simultaneously, just depends on the amount of memory and processor speed, as you can always add more of both, and make the rake receiver scale with visible satellite numbers. Some of those have impressive cold start capability, being able to start from cold within a few minutes, and with warm start capability of seconds, provided the data they have is not too stale.
Big issue is with noise, you find that often GPS signals in urban areas are poor, lots of RF noise desensitising the receiver, and also urban canyons making for lots of multipath distortion, and limiting visible sky to use. Sometimes I need to restart the old Garmin I have a few times, as it is unable to start, but often during RF quiet times it will be up and running in 2 minutes, from a warm start.

@ericlotze7724 Not much about VFD's other than they all die eventually. The SOS construction because you have to grow a film on an insulator for electrodes, and sapphire in pure form is transparent, and making the whole clock in the display area is possible, as the electronics can all be coated with silicon nitride to provide isolation afterwards, except for some bumps at the edge of the device that are built up with aluminium to make the top layer connections. You probably will want to use an electrochromic display instead of LCD though, as that saves a lot of power, though you will still need to have a capacitor to store the energy needed to refresh the display, which likely will only update once a minute. But same construction physically as LCD, just needs a very low current high voltage (around12V) power source to do the update.
Going to be fun to do the crystal drive though, with nanowatts of power available, and typical watch crystals being in the microwatt range for drive. Battery array likely to be a lot bigger and thicker than the display. your wristwatch is going to be Rolex Oyster size, and only rated to 10m depth.

USA missing a socket that is not flimsy. Rest of the planet uses some form of RCD on all socket outlets, USA only in the kitchen and bedroom, perhaps. Here RCD on all socket outlets, and when you do any sort of upgrade from whatever was there when installed to the original spec, gransfathered into the regulations as can comply to the spec as built originally, the only change is that all outlets have to be protected with a RCD, and all light fittings must have a ground connection. You can keep the knob and tube wire if it is still good, keep the rewireable ceramic fuses if you can find the fuse wire, keep the 5A socket outlet with no switch on th baseboard, and even keep the gutta percha wire in the steel conduit, just if you replace a socket outlet to get a 16A plug to fit you probably will be rewiring the whole house to get the RCD not to trip from the leakage in the old stuff.
Yes I lived in a house with an extension, powered off the original overhead bare wire to the fuse box in the kitchen, with the meter there, but the new section had a breaker, and a RCD and individual breakers in a modern panel.

By me LPG is common, and a growing thing, seeing as it works when the power does not, and also the cost is both regulated, and also on par with electricity. I have a gas lamp, which also doubles as room heater in cold weather, and yes I have used it to make coffee at times, especially when camping, when I would wake up, turn on the light, and put the pot on top to make the morning brew, drinking before getting out into the cold.

Most of the drivers here will be "blind" to somebody catching a ride on the back of an open trailer, as the company typically will have, in cab, a camera with both exterior and interior views, plus a live video feed as well, and local recording. So the hikers find the trucker at the truck stop with the right truck trailer type, and ask out of camera view, then climb on the trailer from behind, out of camera view, and the driver gets in and drives. Stop area at destination he stops for "relief at the roadside" and goes in view of the camera, while they climb off the back. Then off to the delivery address, where you typically have armed guards check the truck before entry.

That adaptor plate you made will probably be black anodised, and used as it is on the helicopter. 8 M5 bolts to hold the camera, not going to be a very heavy unit then, probably under 50kg. Yes those vibration mounts are nice, till they get a little old, when you start to find snapped wire rope ends in the mounting area, which start off as single, but rapidly grow to failure of whole wire rope rings. Not too expensive though to replace, except when you have to buy the exact same part, that MM Carr sells, but with the OEM aircraft manufacturer putting it in their box.

No, the machine pays out 4 out of every 5c that gets put in, averaged over a long enough number of plays. The casino will set this high for the low cost machines, as they get the punters/marks into the casino, where they win a little of theor own money back on the slots, and then think they are lucky, and go on to the higher denomination machines, where the house win is higher, and proceed to lose it all.
The only game there that has better odds is Blackjack, where the house, depending on the version played, actually only has a 48 or 49% chance of winning, and there are few enough players that the house can handle the small loss, as they will over time win it all.After all, the house has an entire bank to play with, and the player only has a finite amount of money. Thus the free drinks and such, to get you to lose the edge and make poor plays.

Had that car cow thing, come around a corner to a herd of cattle in the road. Not interested in moving either till they got a little "persuasion", when they suddenly decided that moving off the road and onto the mountainside was a good idea.
Less stressful than a few months later on, come around the corner, and there by the river is a hippo. In the middle of the road, and this one is known to be a little ornery, as she had a calf, and "moved one guy out of the way. He survived thanks to wearing a wetsuit that held all the bits together, and his buddies, who took the half hour drive in under 15 minutes, and blew through the security gate at 150 plus on the way to the hospital. Gate guard merely slammed the alarm button and called hospital to expect a visitor. Around 3 years of operations and he sort of resembles his old photos, and could sort of walk.
When we met said hippo, we reversed back sharpish, and waited 15 minutes for somebody to come the other way, proving the road was clear. They had wondered why the lights had disappeared, but saw no grey mountain with those big white teeth.

Here by me, not in the USA, it is illegal to pass that fee on to the customer, and the DMV accepts both card and cash, no difference in price. however, the number of places that accept American Express and Diners, both with a rather steep rate charge, is vanishingly small, as you can only use them at a few select 5 star hotels, and a few 5 star game lodges, the rest you need to go to a specific green branded bank ATM and withdraw cash. Pretty much all places though will take VISA and Mastercard, which are 100% of the market, and they will give a merchant account to almost anybody who has any form of business, formal or informal.
Person selling sweets by the street side, terminal, same for the big box store as well, as 90% of transactions are card based. mostly based on the fact that cash handling is expensive, and the thing that cash in transit robberies, where the truck is blown up to get at the boxes inside, is a common thing. Drive that truck, or be a guard on it, and the being involved in a cash in transit robbery is not a matter of if, but when.

Inner side of those pass through actually needs to be soldered, or you really need to have used ring terminals there, as that thin piece of garbage plate is actually the highest resistance of the entire setup. Those little bits of metal will rob you of around 10% of the power output, and will run really hot.
Power wise at least they used real copper cable, not the more common and cheap CCA wire. Easier for the power wires to get bootlace ferrules, but as you rarely do audio expensive for the tooling, unless you use it for battery terminal crimps as well, which also benefit from the same crimping. Alternative is some copper AC line, which you cut a small length to fit, and solder on using something with a little more power, like a propane or MAPP gas torch. Been doing that for a long time, that heavy cable sucks the heat away, especially if you use 0 gauge wire, like I did to make decent jumper cables. 5m of PTFE insulated cable per side means the majority of loss is the clamps on each side.
Alternative source for the sleeves is to buy inverter welder plugs, and use the thin copper sleeve they come with. Battery side would have replaced that connector with a new one, one that actually has copper in decent thickness, unlike the cheap one made with a thin copper alloy, that probably has 0.5V drop at full power across it.
Amplifier itself needs to have a proper mounting, not hidden under the seat and not allowed to cool by be buried under carpet, which will make it run really toasty. Mounting behind seat, with the correct hardware ( no drywall, proper rivnuts through the steel) to hold it both vertical and able to have airflow, and with the carpet under it cut away to provide metal to metal contact to get some of the heat out, and it will last a long time. Old one was cooked to death there under the seat and carpet.

Vin is not only on the front windscreen, but also stamped on at least a dozen of the major chassis parts, like the firewall, the chassis rails, and on the floor as well for a truck, though you also get a lot of vehicles where the gearbox, engine number are also recorded, and for Toyota since around 2005 every one does have identidot sprayed on all the panels, both under and after painting, and also sprayed on almost all of the interior panels and dashboard, along with the engine, gearbox and drivetrain, so that you only need to find one to tell that the part is associated with a stolen vehicle.

That Galanz fridge will fail in around 5 years, because they use cheap steel pipe for the evaporator and condenser lines, which are taped to the walls inside and outside, before the urethane foam insulation is blown into position to hold it there. This pipe is going to rust through, because of water condensing on the insulation, and wicking into the gap between the pipe and insulation, and then rusting the pipes through. Normally the pipe rusts through near the entry points in the foam, but you cannot replace the pipe without removing the insulation, and it bonds strongly to the plastic and steel.
The pipe used is cheap unplated steel pipe, with only a thin coating of varnish on it, because the adding of a zinc plate, to keep it from corroding, would mean they need to have an extra assembly step to sand off the coating at the ends, where they braze it to the fittings for the compressor and drier. Takes an extra 5 minutes on the line, so will not be done, just put the cut ends in place, add the acid based flux, and use an induction heater to heat it up and then apply the braze to it. also you can see they do not remove the flux residue, just a quick spray of paint to attempt to keep it from corroding. Funny thing is the compressor will last easily 20 years, even though it is made with CCA wire, and is filled with mineral oil over any other, as mineral oil will move properly through the system with the R600A refrigerant.
Thermostat works on the coil itself, fed through a piece of plastic tube, to be held against the suction line before the compressor. Thus it will only turn off when the cooling is such that the suction to the compressor is coming back at the evaporator temperature, around -10C, and thus saying there is no more heat load there.

Best you can do with that is fill the oil, and start it, put a brick on the loud pedal, and leave it till it does a rod toss. Might get better range than a T72 does in Ukraine....
Valuable parts on it, that adjustable hand mangler, the mirrors still work, and the 4 doors are worth money, plus the rear panel glass, provided you strip the sticker, as spares. Sound system worth a whole $20, some install required, and then the rest can be placed on the scrap trailer, and you will get a few dollars as mixed scrap.

@BigBoyEDEM Can be anybody anywhere. Use some shared accounts that allow them to do things like card transactions, and get a cut of the payment, likely using stolen card accounts as well that have their own scammers running them. Easy with venmo and WU money transfer ( WU is a sure sign they are in Ghana, as it is a very popular way to send money to family there) as there is little way to identify the recipients easily.
Yes whenever you see the scam commenters take the time to report the channel on the channel, you now actually get an email from YT telling you that (about the only time YT actually sends an email these days, for anything other than comment replies) you have flagged the channel. Who knows, they might block the channel, and stop this particular identity, but I see they have a lot of channels, some over 2 years old and sitting waiting, to use for this scheme, as they simply open hundreds of them a week to scam with. Probably sitting with 20 old phones in front of them, all with another scam channel on each, running this scam, and a book with the hundreds of channels they have ready to go, scratching the ones killed off, then opening new ones again to replace them in quiet times.

@mph5896 Last one I did was close to $2k, but that was both head, new seals all round, new water pump and new clutch. Head not blown, but it has to come off to get to all the valve guides, seals and do the valves properly, so all done then. Clutch was because rear main leak, so a new clutch was only the cost of a clutch plate and pressure plate, plus new release bearing anyway. Water pump and timing belt same, they are coming off, why go back on. This was at a shop.

My guess it was there from the assembly on a jig by the loom maker, where it was cut as the sharp ends of the sleeve were put on. Passed the initial testing, and worked on the line, and worked till the vehicle was driven in water, which leaked and was held in by the loom there, and then the wire, combined with the voltage on the sensor, caused it to slowly corrode away. Best trip for doing those kind of joins is to use adhesive lined heat shrink over the solder join, and shrink it down to bond the hot melt adhesive to the wire, making sure to lightly sand the insulation at the area to get clean fresh non damaged plastic insulation, making for the most waterproof join possible to the sleeve and insulation. Liquid electric tape is also good, cover with that, then 3M insulation tape over, tightly wrapped, then again liquid electrical tape over that. Works well on boats to keep stuff in good shape.

Front diff magnets will still grab all the swarf, as the crown will throw the oil past it in operation, though dropping them to the bottom, or replacing with old microwave magnetron magnets, which are bigger, will also work. Plus of course a new set of plugs for each one, top and bottom. Will guess the track bar links will come out as liquid, burn the bolt head off, and then gouge down the bolt, to make it go away along with the bush inner.
Plus of course you do need to get a nice block of sandstone there, so George and Georgina can sharpen the beaks nicely, and probably a rock salt lick, which they will use to do the same. Would also make a nice place, out of the weather, to feed them, so they will associate it with food, and not come into the shed to grab stuff thinking it is food.

You do need to insulate those pipes, and also look into adding an extra layer of insulation on the tank itself, as most of the energy loss comes from the pipes conducting heat away. A well insulated tank will easily hold water hot for 5 days, as I saw when the power was out recently for 4 days, and the breaker for the timer had tripped due to the overvoltage spike causing the MOV surge arrestor to kill itself to protect the timer. Only noticed the water was getting cold after 3 days of power being back, and went and replaced the MOV and turned the breaker back on.
As the tank is rated for a 2kWh static loss per day, off the shelf, i had added an extra 2 layers of insulation to the tank, and had also added another thick insulation layer to the piping for the tank, both the hot and cold water, plus the safety overpressure line, as that copper also will conduct heat. Made a big ball of insulation there with the tank in the middle, getting rid of the 2 big heat loss areas, the pipes and the element cover. Electric bill is now a lot lower just from that, as cooking for a long time has been done with gas. Tank is also on a timer, only coming on for a half hour a day to make up losses, and it really only needs 15 minutes to make up for water use, but because of rotational load shedding times, it is set for either side of the time boundary, so is on from 01H45 to 02H15, despite there being no TOU reduced tariff by me.

Had the exact opposite problem, first CD recorder was HP external, driven via parallel port interface. Had to write it at only 1x speed, otherwise you made an expensive at the time coaster. Later on stripped the case from it, found it was a plain jane HP SCSI drive inside, so moved it into the PC case, and got a longer SCSI cable for connecting it, though still with the passive terminator. That way got it to run at it's full 2x speed without buffer underruns.
Then had a Benq? brand IDE one, which would go all the way to 16x speed, and which had underrun buffer protection as well, so any speed would work.
In general used Verbatim media, found an old box of the ones burned in 1998 or so, and they all were still readable, at least before they had a 30 second bulk erase in the microwave oven.

My father ran a garage, and in the 1950's, it was accepted that a 3000 mile service interval was maximum, and a rebuild every 15000 miles an absolute need, as the old oils and engines would get severe sludge. He did love Galion equipment though, as an overhaul was very simple, the spare parts came in a single cardboard lined envelope, and were a big collection of various size copper seals, and a few neoprene gaskets, as the head used them for sealing, and they rarely failed. Pack of copper rings, and valve stem seals, and some valve grinding compound, oil, filters, and possibly braze up the exhaust manifold because of cracks, and see you again in 2 years, running 24/7 underground in a mine. They dewatered an old digging, that had been abandoned with low price of copper, and found an electric hauler that had been left down there in the 1930's. Pulled to the hoist and brought up, and washed down, then left in the sun to dry for a week. Battery pack taken to the battery shop, where they drained the old acid out, washed the cells, then filled them up and charged for a week slowly to reform, and that battery came back. Loco drained all fluids, washed out with petrol, and refilled, then repacked all bearings, put the pack in it, and sent it back down under. No electronic controls, just resistor speed controls, and DC traction motors that were fine in the high lime water.

@destructionator17 Them calling the bank will have put a hold on that amount of money in your account, which expires in a few days (depends on the bank, typically 2 business days of the hold, though it can be up to a week with some banks), giving time to deposit the check and have it be processed by the ACB with the transaction being finalised and the money being paid into the recipient account.
Been standard with checks and credit cards since at least the 1980's, with you calling and getting authorisation for all those transactions above the floor limit, unless you wanted to take the risk of the check or credit card bouncing, and you eating the loss, along with a RD fee as well. I did a lot of calls to the bank authorisation centre with those, and not many at that time were refused. these days you have online authorisation, though by me checks are no longer acceptable for at least the last few years, though before that your card terminal could be used to do the online authorisation of them, simply by entering the routing info on the MCR ink, and the amount, then stapling the slip with authorisation code to the check and putting it in the drawer for deposit the next business day. But when the government and banks cracked down they reckoned that at least half of the checks that banks received for payment were actually fraudulent, and the banks, along with the Reserve Bank, no longer were willing to eat that cost.

No train this week, and yes a lot of the noise is gone now, just leaving the spindle bearings and the gears to make noise, along with the motor. DE bearing on the motor suffers with a varispeed drive, it gets a lot of radial loading, and wears at the one side, probably a good idea to look on the nameplate and order a set of DE and NDE bearings for later on, though, depending on the particular varispeed you have, changing is either 5 minutes or 5 hours of blue language.
I had the latter, genuine 1970's era obsolete Lenze, so it went to scrap, replaced with a inverter drive, and changing the broken varispeed with a dual drive pulley, with the centre rib machined out, to fit the original varispeed belt, as the other end is "special", so fix the easy way. As a bonus the drive was able to go to even more reduction, with the inverter and the original AEG Ruhrstof flameproof motor in there, which was the thing that killed the original varispeed, as it sat at max reduction for decades. Thank you to Fenner for that fastening method, any size to any shaft with minimal fuss.

Standard German design engineering. The big issue was they had a design for everything, and the US infantry got taught that if they saw field phone wiring how to tell US from German. US you took the wire, stripped off the insulation, and did a linesman splice on the bare wires, then let them fall back on the ground. The German fix was to use cast splice boxes, so the GI's were trained to take those splice boxes and break them, and cut the cable off to use to fix Allied cables.
The German engineers also put in things like roller bearings for engines, and for gearboxes, while the US method was to put in sleeve bearings, and accept that they would only last 200 hours before overhaul, and for most engines it was not likely to last that long anyway, but you could fix in the field easily. Big difference in cost, and for sleeve bearing you are a lot less critical for dimensions, where roller bearings you need an entire factory just to make each part. Sleeve bearing all you need is a fire to melt the babbit material and pour into the cast, then a knife to shape it.

Here by me your chances of getting a ticket are pretty low, but the thing that tells you you are about to get hit up for "cooldrink money" are the cop comes alone. 2 or more you are getting a ticket is likely, unless they all are there to get the money.
then again, last time i was pulled over in a road block was years ago, and yes new years and easter are the times the drunks are out in droves, though the bar is very low, seeing as the most dangerous time to drive is Friday night to Monday afternoon, drunk drivers, drunk pedestrians and vehicles that have the only working light being the one light in the instrument panel. Cars, vans, trucks and semi trailers no difference, you rarely see a vehicle with all lights working, unless it still has paper plate on in the rear window.

South Africa, where it is the most common thing that kills you if you have any other disease. If you are HIV positive it is more than likely you will also get TB, and thus your ARV pack for the month will include as well a cocktail of 4 to 6 TB drugs as well, because the most common strains are already multi drug resistant, and thus need a combination of all the cheap TB drugs to control it. the drugs are free in the public health service, and they are, as generics due to being so old, available from multiple suppliers as well, and cost less than a dollar for an entire month's supply.
Biggest issue is that 6 month treatment cycle, where the patient often feels better after 3 months, then stops taking the medication, because it has some side effects that are not great, and thus a year later on comes back with MDR, and then does not respond well to the common drugs, and thus will either be permanently disabled, or dead within a year.

Ionisation detectors are best when installed in bedrooms, and the optical are best everywhere else. the faster response is a big benefit, and the only contra indication is for those who smoke, where both types will go off with false alarms regularly. The 10 year life is because of contamination, there is a slight airflow, and this with time results in a thin film of debris being deposited on all parts of the sensor and the board, which does eventually result in false alarms. Not the electronics degrading, or the source becoming too weak, but that you need to strip down the sensor to it's component parts, and thoroughly clean them of all contaminants, then dry, and reassemble. Just the labour cost alone will be more than the cost of a new sensor, though the ones that are used in commercial applications are much longer life, simply because they are designed for the cleaning to be done, and thus are a lot more expensive to manufacture.
Incidentally the amount of radioactive material in one of the ionisation detectors is very low, about equal to a few kilograms of coal, and, unlike the coal dust, it is well confined, not emitted into the atmosphere.

Remember the original town gas was formed by taking coking coal, and then burning it while introducing live steam into the sealed chamber, so the red hot coal would as well act as a catalyst forming on the one side carbon monoxide, and also hydrogen, giving you extra boost for the gas stream. The CO was toxic, and the H2 was very much explosive, so it only took a small leak in an enclosed space to get the H2 level past the lower explosive limit of 4%, and thus have the explosion when there was either a spark or a hot surface. The CO was just as deadly, odourless, colourless and would leave the person dead in minutes, with no signs of distress, other than the bright red blood, even hours after death. As well small doses would lead to sleepiness, and thus you would not leave the leak area till it was too late, plus the gas does not trigger any sort of body response, like CO2 does.

Also if you have internet connected appliances, they are all likely being used as bots in a botnet, using power all the time, and all your bandwidth, plus also cooking the processor on the mainboard as well, not really meant to be running at full power all the time. Plus you could have the FBI come knocking on your door as your internet service was used to conduct illegal actions, like serving up NSFW activities, or distributing movies, or sending spam. Manufacturers either have an update you apply, through a convoluted way, that may, or may not, involve pentagrams at midnight on Fri13, and a freshly killed chicken, or totally ignore the problem, saying it could not be them, their products are totally secure (at least till they are forced to issue the recall or buy back on them) and anybody that says otherwise is slandering them.

You can have a headlight with CAN bus in it, great for LED assemblies that can dim when needed, and not be bright when detecting approaching lights. But that also needs ot go to a BCM direct, and not be connected to the rest of the CAN bus, because it is easier to not have a firewall in the millions of spare processor cycles that the body module has when running. Then publish the spec for the commands when the vehicle is out of warranty for the first one, so anybody can make a compatible headlight, and no need for a serial number, or make the tool to add that new serial number free, or very low cost, so the manufacturers of all the scan tools can add this to the vehicle database they use.
After all many scan tools allow key programming, which arguably is a much higher security risk over a headlight swap, as having an aftermarket light is, so long as it is DOT compliant (not to go into the crappy US headlights, using a spec from pre war, and not even sure which war they decided on, so all are great at glare, and poor at light), not going to be a safety risk.

Willing to bet that the ticket was a camera, but that if she had been pulled over and breathalysed she would also have blown well over the limit. The cops probably did not have a breathalyser there, and also they were going to simply do the speeding ticket, and lock her up for the differential over the limit posted.
Also can bet that she had not updated address for the DMV a few times, and figured out that this was an easy way not to get tickets, and also gave old ones when pulled over as well, so they could not serve her. Number indicates at least one a month, so she is likely one who skips red lights, drives at high speed, and catches all the speed cameras and red light ones, along with all the officers who pull her over as well. either needs to be slapped in jail, or be banned from driving, and told to take a bus or train.
However by me almost no speed cameras, other than main roads.

Organised theft will simply clone the authorising machine, and then simply unlock the stuff before selling it, so this will not stop them. I see the only things with anti theft on them by me being expensive instant coffee, and baby formula. The razor blades are behind the counter with the cigarettes, right at the front of the shop, so you buy them there.
Disposable razors though, which use the exact same blades in them, made on the same machine, however are in the shop in a pack of 10 or 20, and are just on the shelf. You can guess which ones I buy, as that pack of 20 will last at least 5 times as long as the single pack of 4, non disposable, razor blades, but cost only a quarter of the price. Often the exact same blade cartridge as well, just solvent welded onto a cheaper plastic handle.

@calm4477 Yup, fifth owner could not afford to maintain it, did it on the cheap, used the cheapest oil, and ran it long past oil change intervals as well.
The lawn mower plug I can understand, they needed a plug for another engine, this car was in the shop with a guaranteed never run again engine, so took the plug, probably to diagnose a misfire to either plug or lead. Then took faulty plug, and returned it to the supplier as faulty, and needed a plug to put there, so grabbed that old knackered out lawnmower plug they had in the tool box in the car, and shoved it into the hole. Then took new plug as credit, and used it when they needed to service their own vehicle, with the oil coming from the work in a few "empty" containers.

Oil changes are needed, and the factory interval is calculated to get them out of warranty with less than 0.1% of the engines failing, and needing warranty replacement. But the services are often part of a maintenance plan, so they want to spend bare minimum on them, as they cut profit.Change every 3k and they need 11 services maximum, before warranty or free service expires, and every 12k only 3 max, a big profit away from the dealer. But also that warranty is time based, so all the parts will fail after 5 years or so, again profit, in that they want to use the cheapest part that will do 5 years.
A thing to note is that eg BMW offered a motorplan that you could have up to 20 years of full coverage, only thing you paid for was fuel, tyres, alignment and top up oil, plus accident damage. Covered the entire vehicle, all parts, no hassles. Now only 5 years, and you can only extend to 7. You wonder why, it was costing them more on older vehicles than they made off selling them. Know one person who did his extension to 20 years, paid up front, and 3 months after this sunroof packed it in, and needed to be replaced in entirety, along with the interior lining and airbags. Cost of parts was more than the entire extension of plan by a long shot. He paid a $10 bill for "sundries", which was cloths, and the car wash.

@HumbleMechanic For you they are cheap, but for the rest of the world they are an expensive item, so I would want to keep it as good as possible, in line that in future i might want to repurpose it. Adjustable feet a good idea, and I would also apply the same surface protection to the underside, as that will at least keep the warping down if you live like I do in a climate where you have considerable humidity swings between seasons.
Would also add a row of socket outlets underneath, along with a desk hole and cover each end, so that you can have things like cordless tool chargers and such neatly arranged, but with the power cords out of sight and clutter. A length of slotted conduit as well under the sockets to hold the cord excess, and then a box and switch above, so that you can turn the whole lot off with a single switch at night, reducing the fire risk from dodgy wall warts.
If going the whole hog would also add a length of LED strip under the front, along with a switched power supply, so that you have easy lighting when down on the floor plugging things in, or fetching stuff from the shelves.

Yes they can seize the money order or cashiers check, under the claim the money, or instrument, is being used potentially fraudulently. Then cash it, give all to the feds, who give 50% back, and you are SOL. Cops do not raid banks, because bankers have lawyers on retainer, who will fight to the end of time over $20. But a bank robbery, there is always a difference between the amount the police claim to have recovered, and what the bank lost.

By me in South Africa the council never used SOX lighting, they moved from incandescent to mercury vapour, adding in the ballasts to the existing fixtures, then replacing them with new integrated fixtures. Residential went from 150W incandescent to 90W mercury vapour, while main road went from 500W to 400W mercury. Later on there were "upgrades" to 400W HPS lights, with relamps getting a blend of HPS and MH lamps. Now they are slowly using up the stocks of lamps and fixtures, using them for spot replcements, after doing some replacement actions to replace whole streets with LED, 77W and 130W for main roads, and 35W for smaller streets.
The only user of SOX was the railways, with them using it in the yards as light, only later on going to HPS lamps. they even used it in stations on trackside, passenger areas being done with flourescent fittings. Only place I saw SLI lamps ( the rarest low pressure sodium lamp) was in underpasses with a rail overhead, used to provide light 24/7 in there, though those eventually were replaced with MV and then now LED fixtures.I do remember travelling as it got dusk, and you saw the rail yard light up from the high masts in a neon glow that changed to monochromatic orange as the lamps warmed up.
Only reason SOX lamps fail is the filaments wearing out, or the glass seals get eroded away by the sodium metal dissolving the soft glass that is used, as quartz glass is resistant to the sodium, but the seals have to be a borosilicate glass, and this does get attacked, which is why these lamps are always run with the base elevated, to keep the liquid metal away, and slow down the erosion. the lamp runs really hot, the metal has to melt and give off vapour to operate, so early lamps had a Dewar flask to keep them hot after warming up, while later ones used an Indium metal coat to reflect the heat back onto the inner arc tube, no second outer glass Dewar needed.

@philipdw6954 No, that is part of the CAN bus wiring which is not used here. The ECU will detect wheel spin or skid, and command the brake module to brake a particular axle and at a particular force, so as to stop spin or skid, while at the same time reducing regen on the skidding wheel so it will regain grip, or reducing power on take off to prevent spinning the wheel. You need the rest of the control system to do this, the booster currently is operating (and crying for help on the 2 CAN bus connections it has, about loss of other visible modules) in a degraded direct action mode, merely boosting the linear pedal travel.
Hopefully also those bolts for the brake pedal and the booster connection also will get a thin coating of grease on them, so they run smoothly, and do not sit bare metal to bare metal forever.

@Foobar_The_Fat_Penguin Costs money, and hospital IT is notorious for being scrooges with money, saying it all works, so no need to spend any money on it, and using it to refurbish the admin offices and the front lobby. Go into any hospital and look at the back areas, you will find corridors with no lights, leaking roofs, and water leaks all over, because the administrators do not see this, nor the patients, only the staff. Only time they will spend is after the collapse, then look for somebody to blame. Either some worker with no purchase authority and only able to send the requests up, or some person who left 15 years ago.

Automatic gates are easy, just look for used pneumatic gate valves, 4 inch size, and a couple of flanges for them. then a few solenoid valves with the air supply in the shop to control them, with either manual actuators at each machine, or an electric solenoid to control the valve, powered with the machine power.
Suitably steampunk appearance as well, with large diaphragm heads on them, and the gate that slides up and down, just need 2 pneumatic lines to each one to control them, and if you only can get proportional ones you can still use them, though then you need to either remove the pneumatic amplifier or run a third air line to provide the power air.

Good job that, most spray painters I see need to apply 20 layers of paint, so there is something to polish off to get a final coat that is not horrid. a few thin coats correctly applied is beyond them, as they are under the impression that paint cannot give a good finish without a lot of polish to get rid of the powder coat and the dull overspray. Done cars before, where the finish out of the gun was almost perfect, and nothing really other than a wax polish a month later was needed. Of course, did this in summer with a retarding thinner, so the paint would not be fully cured half way to the metal, so that you got a liquid finish on the car, so a lot of light coats instead of buttering it on thick and dry like spray painters, who regard the polish job as "somebody else's problem", and who want to be done with all coats in one hour.
But even on new cars you see poor painting, with orange peel very evident, and then covered with a few clear coats to reduce it. Needs a lot of aftermarket polishing with abrasive polish and then good paste wax to get that nice.

Insurer will never put the title in their name, simply because they then will have to deal with the thousands of parking tickets, fines and renewals that will them come due. Rather leave it in the original owner name, and flagged as stolen, and let the owners deal with those headaches. After all, a stolen car can still accrue toll fees, tickets and such, and the insurer is not getting paid to fix those, which reflects badly on them because their own vehicles will get title holds on them for the unpaid monies.
If it is found original owner gets first option to pay for the recovery cost, and if not then the vehicle lands up either being sold on auction as non runner for scrap value, with the VIN numbers stamped over with a clearance number issued by police, or gets crushed and sold for scrap metal value.
Incidentally Toyota has been marking all vehicles manufactured at the Prospecton plant, irrespective of destination market, with Identidot markings since 2013, along with all other manufacturers, and all importers as well, in an attempt to make all used parts identifiable, as the dots are sprayed on all metal parts, and also on a lot of the plastic parts as well. Each one has a serial number associated with the VIN, and only a single one showing up on a vehicle with a reported stolen VIN gets the vehicle classed as stolen property entirely. They show up under UV light, and are hard to get all of them off every part. As well Toyota marks a lot of the parts with the VIN, including around 40 of the major parts getting a VIN sticker, laser etched, that is applied before the paint is applied, from the sheet of around 80 that starts off at the front of the line, and which stays with the assembly jig all the way down, and which gets applied every few stations. Engine line also has another sheet, applied to most parts as well, so that when they are merged on the line the sheets are matching. 3M VHB adhesive on the tags, which does not let go easily, and which once cured is resistant to most solvents as well.

10 year olds by me are often the head of a household, because either both parents work full time, and thus leave at 3AM to commute there, and arrive back at 9PM, leaving the 10 year old to feed the other children, get them ready to school, walk them to school, and go to school as well, and same in the afternoon to collect them, feed them and care for them as well.
Of course a lot of families where there is just the mother doing the 3AM get up, or living in at the work as a maid, or where both parents are dead, leaving the child as de facto fully responsible for the home.

Just me being glad there are nice new slings, complete with a certificate, in the shop now, instead of the old tatty ones?
I would have had that scratch filled in with Pratley quickset putty before doing anything, at least where that rest is running, so as not to damage the cam followers in the rest, those are expensive little bearings to buy, and doing all three at once will be a $300 extra on the job. Yes those threads should have at least had a coating of non drying sealant on them, that is a very common thing, and should have been there from the factory at least, along with a second seal to protect the thread area.

@JonFrumTheFirst That varies from state to state though, some do and some don't. By me, not in the USA, all that is needed would be the inspection when bought, which amounts to do the lights work, does the horn work, does the windscreen not have cracks in the visible area, does the suspension not have excessive play (joke on a Hummer), does the engine and transmission not have visible oil leaks, and do the brakes pass a minimum level, do all the doors work, and the seatbelts (if fitted, plenty of pre seatbelt law vehicles still on the road here), plus a road test to see it does not have too many rattles. After that nothing, till you sell it again. So you see many vehicles best described as rust moving in close formation, and vehicles that resemble the Exxon Valdez

Turns out making the belt for the oil pump both out of rubber, and also making it swim in oil, and also putting that oil pump down in the middle of the engine, so you have to strip the engine down, out of the vehicle, can be an issue. Timing belt also runs in oil, and also they make it that changing that set of belts is really difficult, and to change that oil pump belt and tensioner you have to strip the entire engine down.
You can bet that Ford will tell the techs to put the old timing belt back, along with the old timing belt tensioner, and to use RTV sealer on all the parts, as they will supply only a belt, tensioner, and give them 2 hours labour cost back. You can strip that engine in under 2 hours, out of the vehicle, see Eric of IDoCars channel, but putting it back is not as easy, takes a good few hours, and the parts you need to replace is a lot more than a belt and pump. Now you know why that engine is also nicknamed the EcoBoom engine, and they are in demand as replacement engines in good condition, at least as a usable core to rebuild where the oil pump belt failure has not destroyed the engine.
Because running it with a broken belt, and the oil light on, will destroy that engine in under a minute. Belt sheds teeth, starts running the pump slower, oil pressure drops, and it destroys valve gear before the shed teeth clog the oil suction line, and the pump destroys itself, sheds glitter of doom into the engine, and the oil light does eventually come on. Ford should have issued a new engine, because that old one is only scrap, rebuild cost exceeds value of the vehicle. Belt used because it is a few dollars cheaper than a chain and sprockets, and also gave a 0.001 MPG improvement in fuel use, and 0.1dB lower engine noise in test, but they also saw the belts would not fail till the engine was out of warranty.

Only in the USA is the roll sold in 8. Here by me in either 6 or 12, and the mystery meat is sold in a variety of ways. Either as a pack of 7, because 7 comes to a half kilogram, or for others as 12, 10 or 11, because that is a kilogram. Thin, thick or the South African favourite, boerewors, coarse ground meat, fat and spices in a thick casing. To be classed as boerewors you have to meet standards, otherwise it is just sold as sausage. 70% meat, and 20% fat at a minimum, and yes pretty much any animal can be used, though traditionally a lot of the meat is pork.

@alexatkin Race to the bottom price wise, meaning they cut corners on every part inside. If a part is 0.001c cheaper, but will only last 1000 hours, it will be used instead of the part that lasts 10 000 hours. Same applied to every part, including the light emitting part, where the current is so high you get appreciable lumen degradation within 100 hours, but the initial spec is still met, and lifetime is slashed.
LED the same, you get all sorts of claims for 100k hours, but the actual LED units will never be run at the rating, instead run at 5 times the 100k hour current, and run so hot that they are just short of melting themselves free of the board. If you are lucky they will do 2000 hours of running, as the manufacturers know almost nobody actually writes the install date on a lamp, and keeps the invoice (printed on thermal paper that fades to invisible in 6 months as well) to claim for the failures, plus the QC on them is essentially zero in the plant, just a check the unit is assembled externally before putting in the box.

Same here in South Africa, though only Audi, VW and Seat used to have a few models sold here, though pretty much all the VW Golf models here have the plastic mouldings internally stamped with Seat, as they use the older EU models as basis for the locally made models, reusing the trim parts a lot. Common parts are very much a thing, though you often can save a lot buying from the VW spares department by using the VW part number instead of the Audi part number, despite being the same part, in the same bin, the end use vehicle determines the price. Or go to one of the many aftermarket places that can basically sell you the entire vehicle, less only the VIN plate.

Pilot training is normally like college debt. You go get the training with a loan, or you do it the most common way, and sign with Uncle Sam for 3 years of training, with you having a pay back period of 3 years before you can leave. However the airlines do tend to look for the best, and hire them, paying the money they owe to Uncle Sam, which is cheap compared to doing it themselves. Plus zero risk, and they sign a contract with the airline for a similar number of years, but with a higher pay, and the airline does all the training for the particular plane at their cost, so long as you finish the contract period.
This case however is like you getting a job at the wall of malls, as a shelf packer, and after 6 months you decide to leave, with the wall of malls then telling you that, because you are now a skilled shelf packer (but still on minimum wage pay), your leaving means you now owe them more than the pay you got in the 6 months, due to them "training" you on packing shelves, or pushing a broom, or driving a mop and bucket.

Yes, have seen my local copy of the standard kilogram, it is only 10km away from me in it's armoured vault. Also have masspieces that are only 3 steps away from it, having been verified by a massmeter that was verified and calibrated with one of the sub masters compared to the local standard kilogram. 1g masspiece that is 1g with 4 zeros after it, any more and air pressure and bouyancy has an effect on it, which is why all those tiny measurements take place in hard vacuum.
The smaller masspices you cannot use in atmosphere, unless you measure your local air pressure and humidity, and compensate for the amount it bouys up the tiny masspiece, and, measuring that 100mg masspiece, simply moving your hand into view of the massmeter the IR radiation from your hand will make a change in the measurement.
Nice when the company coming in to do the verification uses your own masspices, simply because they have a fresher certificate, and they look at the long term drift and can see no trends, except for the one where it jumped up by 0.5g, which was because, a week before they went in, I took them stripped the paint off, and then gave them a new coat of primer and black, leaving a week in heat to flash off solvent. Yes also had the cotton gloves and wipe cloths, to make sure they stayed dust free and clean. The sub 200g ones had a separate box with the tweezers as well to handle them.

@hypothebai4634 Supposed to have a redundant set of diesel power plant to provide power, but likely there was a few of those sets that were out of order, and awaiting being under way to be repaired, or at least beaten back to life. Could be that there was only a single power plant operating, and then a backup unit not running, in place of 2 sharing the load, and a steering command drew too much power off that single plant, so it tripped out, leading to the blackout. Main engine will carry on for a while, as it runs all mechanically, until the fuel feed pumps stop filling the header tank with the inshore diesel fuel. Black smoke yes captain put all astern to slow down, and dropped anchors, once power came back on from standby genset, as likely the emergency generator was started by the engine watch, taking a minute or two to come on line, and then they started the reversing, likely with a corresponding massive steering input, which would be useless without any headway to give the rudder authority.
Going to be a massive collection of blame there, starting from the port authority, the captain, and exactly who is going to pay what, with insurers doing their best to not be the one on the hook.

The original layout was so the lots could later be split with a panhandle, but instead later on they were split with eg 12, 12A, 12B, 12C for the lot divided into 4 smaller ones, so the unused numbers were allocated further down when the road was extended.
By me there is a road with 2 names, and a join in the middle. however house numbers go up from the one end, so the one road goes from 1 to 31, and then it becomes the other road, with 32 to 68, because it goes around some curves along the way, and thus there are different size lots. 68 actually would be a dead end, except the third road continues, with it's own number system, so next to 68 is 17. Postman gets confused.
Then next door to me there is a road, marked on the maps as 134 Street name, and the houses on it are 134A, 134C and 134D, with the one nearest the road being 156, because they actually do have a street front onto the street, and this is the back entrance, and the only vehicle entrance.

@jaydunbar7538 state regulation by central government, giving a basic set of rules that they cannot do any more restrictive rules, and where the laws say what are the avenues available, like with commercial law, are a good start. Basic conduct, basic reporting, standards for elections and transparency are needed, not a totally unregulated thing as it is in the USA at the moment, with each state having different sets of rules. Basic set, that states could add to ,but a basic rule set that applies to all are a start.

Walls pressure cleaner with industrial detergent, and then rinse, then you spray top with white, and bottom with the gray. Floor hit with the detergent as well, it will help a lot with dingy. Holes cover with a plate from outside, before you paint, and use rivets to hold the patch in place, then paint it inside to make it less noticed, though bondo over the dip helps as well. Roof try to get new tiles, the old faded ones absorb a lot of light, and while there get some insulation in as well, even 2in of extra batting helps with the heat a lot.

@50PullUps Even the volatile memory, things like the clock and such, like stored state in RAM, will stay for a long time, kept there by the phone battery, and also by the small coin cell soldered to the main board that is used on phones with a removeable battery. Lithium cells will last a long time on a charge, 2 years is not a long time, they will do 5 years from a full charge, and not be under cut off voltage, keeping things like the standby processor, which is looking for things like power button press, USB connections, battery state and such, with no problems.
The processor spends 99.9% of the time in a very low power state, only turning on briefly to update clock time once a minute on roll over of seconds, and in the interim having low power consumption, basically the low power 32kHz clock crystal that provides the clock, and almost nothing else, while waiting for the hardware interrupts to occur for change of state. Then start the low power on chip oscillator, execute the code, and drop back to deep sleep mode again. The high power mode draws under 1mA for a fraction of a second once a minute, which will be less than the self discharge of the lithium pack.

@abdul-kabiralegbe5660 12V8 with high engine compartment temperature is correct with a fully charged lead acid battery, as the terminal voltage, which with a fully charged battery is 13V8 at 25C, is going to drop as the temperature rises. Older alternators that charged at a fixed voltage, 14V4, or 13V8, irrespective of temperature, thus would overcharge the battery, causing it to lose electrolyte due to it being split into hydrogen and oxygen. Some sealed batteries, and some more expensive refillable ones, have a palladium catalyst in the vents to recombine this to water, slowing down the loss, but you always had to add pure water to the battery to give it a long life. Thus checking the battery water, and filling up at each service. Sealed batteries are the exact same now, just there is often a cover over the screw off caps, and they say sealed for life, as they know there is enough water there to get you out of warranty before a cell boils dry, and you buy a new battery.
Pull off the label, see the caps, and check the water, and you get many years more service out of them, and check the water monthly as well, even if it means you have to remove the hold down and the terminals to get to the caps. Done that to all mine, and got to see that they would last 5 years just filling up every 6 months or so, all cells taking around 100ml of water to fill up again. Otherwise would have had the battery fail around 25 months after buying, just outside the 24 month warranty. OEM battery had caps, but was never checked, despite it being part of the OEM service routine.

Saw 2 car dealerships that did that. First was a long established one, dealt mostly high end vehicles, and owner decided to retire, with around 3 months worth of sales that he sneaked out of country, and vanished along with the money. So the partners, who he left holding the baby with a very dirty nappy, had to make the sellers and buyers (plus the banks who gave the financing on both sides, who both lost out) whole. they still want to "talk to him", dead or alive, though they prefer alive, to get the money back.
Other one was similar, opened up, were doing consignment sales for around 6 months, then one day vanished, along with almost all the stock, and leaving behind a set of angry buyers who had gotten financing paid over, and sellers who found the vehicle was missing, and the shop had sold some of them multiple times before taking the vehicles cross border to sell illegally there. Only one left was a Jeep, mostly because the engine and gearbox was in the rear in boxes. Eventually building went on auction, and was sold as well, because they also took that money.

@Ynalaw Yes, but that then is you interfering with the property, the laser is not, as you are merely "shining light" onto the property, and if he is legally allowed so are you. Though if not laser then a call to rent a 20kW Xenon short arc searchlight, aimed at the fixture till it catches fire, will also work, as after all they did not have a max light amplitude, and those lights are often rented out, though with a caveat not to aim them at property within 100m as they might burn it from the intensity of the light beam. Does need to have it's own 50kVA generator with it, and a good amount of cooling water as well to keep it running.

Will bet the info came from the call centre the cruise line uses. They after all have her name, SSN, all banking details (they ran the card to book it), a copy of her passport, plus her address. So they copied all this, and then had an accomplice or thirty five go down to assorted branches of Chase, plus other banks, and applied to them for extra cards, to be delivered to her address, and if the bank did not have an account for her, they then opened accounts under her name. Then somebody was waiting at her house to collect the mail deliveries of the cards, and because the USA still allows swipe and sign, plus will deliver a card in the post, they would have, had she not arranged with the post office to hold the mail, and also have the mail be previewed, she would have found out 2 months down the line she now owed Chase close to $600k in debt.

Only reason for self checkout is to save staff costs. If the stores could do a 100% automated shop, which has been done, with some very fun statistics about the errors that can happen with that, then they would do so, and get rid of that pesky labour thing.
Of course overlooks that if all stores are automated all the staff no longer shop there, which in a lot of stores actually is a measurable part of the sales volumes, especially for those who do so for family there, with staff discount if available. Plenty of stories about stopping staff sales resulted in a marked decrease in sales.
As well automated checkout can and does often make errors, either for or against, and you would never find the store reviewing and refunding the customer later on, even if the customer did not see this in the bill.

No need for heat by me, as it is early morning, and it is already 28C outdoors......
The issue with short cycling is the sudden heavy heat load in the motor windings, and also the torque shock on the motor mounts. Typically a compressor fails because the windings have the connecting leads fatigue off, or the motor windings develop a shorted turn or open, or the internal mounts break. almost never from bearings failing, unless it is a scroll, which will eventually have wear make it pump less efficiently, or for a vane unit the vane wearing and losing efficiency. Most common is the windings, or the case rusting through because of condensed water on the inlet side rusting the case through. Oil wise the worst for it is a leak that allows moisture in, or high temperature that degrades the oil.

The cover on the new lights is also an anti tamper seal, so you do not get one that got used and returned because it was defective in some way, or was incorrect for the previous buyer.
Lamps buy brand name, I prefer Osram or Bosch, as they are both OEM lamps, and are good quality, and widely available. Cheap ones you get what you pay for, some last a week ,some last a month, but buying your common lamps in a pack is worth it. Also, for headlights, change both as a pair, especially if they were original, as one failing means the other will go very soon, and often the modern vehicle the labour is high, as you have to remove a front bumper skin, fencer inners and a grille, so changing the other is cheap insurance.

Well of course, truck brakes are not meant to be applied for 20km down a hill, that is why you have an exhaust brake, jakes brakes, and a retarder, plus the sign at the top saying heavy vehicles must stop and engage low gear, so the engine can do all the braking against compression. Flew over the top at 100, and around 1km down the brakes get too hot, expand past that the drum actuator S cams will go to, and then no brakes. Cannot change gears down, because the gearbox in neutral cannot get the input shaft up to a high enough speed to engage the lower gear, and now it is a runaway. Saves 1 minute off the time to accident in total.
Also due to roadworks arrestor beds are closed off, so back to how it was in 1970's, except there are 50 times as many trucks, and no more traffic police doing spot roadworthy checks there on the top of the hill, like they used to. They would check, and at a minimum you would get a fine for a blown bulb, unless you had spare bulbs and tools, and changed it there, when you would just get a warning.

Tough little things, as you will know if you ever got one while fishing. Thought it was the biggest catfish ever, and after a half hour of fighting out popped this little turtle about side plate size. Was fun getting the hook out of there, those jaws bit hard, and both front and back end are dangerous. Long nose pliers and a bit of work, and away he went, even more angry.
Was walking on the road one day, and this turtle was crossing. So, picked him up by the rear third of the shell, because head will not reach that far back, and game ranger comes up and asks what I am doing. Replied he wants to cross, so he will get a free trip 5m off the road for this time, as I do not want him run over. Got to be careful of the back end as well, it can spray stinky poo pretty far as well, and the smell lingers a long time.

South Africa, where we used to have a semi functional rail network. the price for a month ticket was cheap, equal to $5 for a month of travel, where the alternative is a private minibus taxi, which works out at $4 for the one way, each day. Still 2 lines semi running by me, with a morning and evening service for commuters, but they are slow, oft delayed by failures, and overcrowded, because they are cheap.
As to lines on the coast, there are a few independent private railways around, where they run trains that run along the coast, and there is good enough support from tourists, when they are allowed back, to hopefully keep them running.
Rail does show you though just how apart places are, which is not appreciated by flying, or even driving, as the first you arrive fast, and the second you are concentrating too much on the road.
I used to catch a train regularly, and the price was very low, 5c US, which was a single stop ticket. Just had to keep in mind the train schedules for which trains were express, and which were all local, as not all stopped that stop.

Yes, avionics we were taught that high stress areas and a split pin, replace when removed, as it is a very cheap item, but the failure of that joint is not. so i keep that big box of assorted split pins in the shop, and when I come to one snip and toss, grab a new one. As to the install pretty much the standard has been it must not move. so tap the head into the hole, bend over the top of the nut, and back down to the head , and cut off flush with head for that side. Other end tap down, flush with the nut. Only other was for pins that are there for pivots, where it was tap head hard in hole, and bend tang back around to be cut off next to head, as the split pin could not fret then and wear, and it was, along with a washer, the only thing holding that pin in position.
Locking wire done plenty, had the holes to prove it, but was lucky I did not do engines, where you have a single locking wire that goes around the engine every segment, that holds all those fasteners with a single wire, and it has to be correct every time. That one lock could take a day to do, and inspect, per engine ring section, just for the locking wire alone. 20 odd case sections to bolt together, and most of the fasteners there are all single use only, so there was a massive box of bolts and nuts that were free to use for anything else. Sheet metal shop used to make sculptures out of them, in lovely colours, as the titanium bolts hot to different temperatures as they heated up. Same for rivets, still have the odd bottles of assorted left over rivets that I use for joining sheet metal, as they are perfect for this, and better than pop rivets.

Shock and horror, by me an entire traffic testing office was arrested and charged for fraud and corruption, for issuing false drivers, false CDL and also issuing false inspection reports with no vehicle present.
Though most drivers the pre trip inspection consists of walking to it, getting in, and seeing if it starts.
The shock and horror was that this actually was reported, as bribery is rife there, go do a test without a bribe, and you will be failed, but pay the bribe and you will pass no problem, even if you cannot start the vehicle.

@michaireneuszjakubowski5289 Thing is that as a single aircraft it had a very limited lifetime, your airframe needs periodic inspection, and this is actually more expensive than building the aircraft new again. Hopefully they will build at least 2 new ones, as the cargo capability will be used for sure, and having two or more makes the cost so much lower to maintain, as your costs to manufacture is not linear with number, and building 2 or more, with the knowledge from the years of running the first one, will not be as expensive, as the new ones will have all the fixes that went into the first one, and thus will be much improved.
Yes it needs to be rebuilt, another casualty of this senseless posturing.

Do not think you want to try the oil for piston engine aircraft. That looks like thick syrup when cold, and only gets worse when frozen. You almost have to use a spatula when cold, but after the engine is warm it runs like water.
Jet engine lubricant is more of a hydraulic fluid, it has to work well over an extreme range of temperatures, as it will be used both in freezing places, like actuating the cylinders that are on the wings, and the same fluid will also be in the engine cooling down parts that are at 1000 C on the one side, but have to stay cool, so the fluid has to absorb that heat safely. Works because the flow rates there are kept high, so the oil can be moved to a heat exchanger to dump the heat fast. The fluid is also regularly sampled, so that wear particles can be examined, so the condition of the whole system is kept good, plus the filtering is very good to keep particulates down to a very low level.
Just do not get it on your skin, the additive packs in jet fluid are very toxic in a lot of cases, and it is incredibly hard to remove from skin without very aggressive scrubbing and lots of harsh soap, and clothing soaked in it is almost impossible to clean without boiling for hours in industrial detergent solution.

@theoneandonlysoslappy No, the only way is to integrate the key store with the main SOC, which is what most manufacturers do. However, the phone storage is too large physically to fit into the same chip, so it is spread out over a few large flash memories. To protect them the manufacturer encrypts the data stored there. So now they have to take a number, run it through the decrypt software, which is open source, as there is nothing secret in it, and then check to see if they get something out that looks like a filesystem with valid data. The current best methods, which the 3 letter agencies use, is to take those chips off the board, put on a test jig to read the data, and clone it into another chip, then put the original back. That cloned chip image is then used in a very large compute farm, because you are going to be running thousands of guesses a second on it, and they attempt to get a valid filesystem to come out. Basically if it is a good passphrase, which, by the magic of the one way hash function it is, they have to use all 2 to 128 hash values, statistically, to break it. They use a rainbow table, generated by running dictionaries through the hash, to guess the most common passwords, using the leaked passwords that you can see on haveibeenpowned, and those are the most common, so are fast as they already are in the table. 175 million, likely they went through that list, then started on the empty space between. Use that nice big 3 letter agency datacentre in Utah, and they might, with a decent enough passphrase, be able to break it before quantum computers become big enough to do it. If no quantum computer then the sun will go nova first.

Will tell you of a water pump deciding it was tired, and seizing. 12km out of a small town ( easy to remember, because at that point there was the "Welcome to Ermelo/Ermelo verwelkom jou" sign, and normally 310m past that was a speed camera, in the now 60kph zone), and we went from 120ish to 40 in about a car length. Coast and pull over, then turn over the engine with the crank pulley, no binding. Start up, running, but rough water pump. Note Ford CVH engine, water pump runs off cam belt, and this is an interference engine.
So drive the 12km to town, pull in at the garage, across the road from the Ford dealer. Go there, spares closed 4PM, but they say try the spares place next to the garage. Now, 5 to 6, and go into spares place, and ask him for a water pump. He says no stock, but there should be one at his other branch. Quick call, and 5 past 6 in walks the other shop cashier/manager/stocker, with a new non OE pump. At the same time my friend walks in, with the old pump. Spares guy asks where is the car, and we point to the red one outside, with the open bonnet. He asked how, because we pulled in 20 minutes ago. we had done a few water pumps on those engines, because it just so was the one engine in a custom piece of equipment, and yes they did rather fail a lot, so he had gotten really good at changing them, plus on his car he had cut the cover, so he did not have to remove the crankcase pulley like the manual said. Paid, and 20 minutes later we had fitted the pump, filled up with fuel and water, and were off, also having gotten the dinner for the road in the cafe there.
Another time drove down with the exhaust in the car, because at night we found a log, which popped it off the front connection, and bent it slightly, and tore the hangers all off. So a very loud trip down, with exhaust ending just behind the firewall. Next day exhaust place fitted it back, after making it more or less straight.

Hard, as the DM senders get to know exactly what alphabets to use that bypasses these filters, and then add spaces to the numbers, or again non latin charaters, to obfuscate to the very literal machine, but the human recognises it as a platform and a number. If YT cannot stop this spam, having full control of both the source of the message, and the location of sender, plus a history of posts, with the best AI they can develop, very hard to fix.

They are simple to prove, as they would have both his fuel receipts, and be able to claim all that money back (including the tax on the fuel that he would otherwise have had to pay), along with all the mileage, service and depreciation at the IRS rates for that period. Then in addition the payment also includes his full salary and benefits, plus the tax paid on his behalf, plus the benefits. Likely he also lost his entire government pension as well, which likely is part of that payment, leaving him with the shortfall he now has, along likely with a tax bill for the undeclared income.
By me this is all too common, with things like a vehicle using 5000l of fuel in a single day, for a sedan vehicle that was billed to it, while the vehicle was sitting parked at the government garage after being involved in an accident, and being totally undriveable. But according to the fuel tag the vehicle had filled up at multiple garages, multiple times in a 24 hour period, about 15 minutes apart, all with the tag built into the vehicle.

Yup had the same. New car for a sales rep, and he drove it to 60 000km, with the factory oil and filters still in it. He was fired, not for that, but that he got a speeding ticket. ticket was for a day he was supposed to be in an area, and had sales calls marked as done, yet he was 6 hours drive away. Then they looked at the toll and fuel records, and saw he was driving Thursday there, and going back Tuesday morning, yet still had calls and sales for the Friday and Monday at the places he had on his list. Small sales, so they looked and saw he was phoning them. that area went to another rep who was phoning, and she got nearly triple the sales volume he had at any time.

Know of one development that, 20 years later, still cannot get any bonds registered, because the builder built 1 metre over the property line. Problem he has is that the land he built on is not the neighbouring land, but a nature reserve, so now he has both the municipality, the local wildlife department, and the national government all sitting on the other side of that case, and he will either have to demolish 5 of the units, or rebuild them smaller, in order to move that fence the 1m back. Still in court, and always getting dragged out to a later date every time, but meanwhile all the units are rented out instead, because that is the only way to get money out of them, as they cannot be transferred.

Funny thing is that the local owned by Walmart chain has a entry card, and they have a record of every purchase, with date, price, type of payment, and store location, ever since I have had that card. Asked one day what do I buy, while they were looking up a warranty claim, and she told me I buy a lot of sugar, tea and coffee, which was correct, as I used to do all the company shopping. Asked the furtherest back, and I was told the day I got the card, and what I bought., at the time 15 years before.

Gender affirming care equates to them providing saline bags, silicone butt implants, cheek fillers and such, and for men moving tendon attach points, and implanting inflatable bags in a certain place, and also putting falsies in after one dangly bit is removed, plus also keeping the tip. This in addition to the usual botox, skin stretching, and nose and ear jobs. also putting in hair plugs, so the comb over can go away, often using hair from elsewhere as a source of the plugs, typically armpit and elsewhere.

@donk5058 Look on it as area denial, you do the classic "one pass haul ass" and send them in, they get out of there before you get a heat seeker up your exhaust. Keeps the other side down in cover while your infantry grunts can move with nothing coming back at them.
If you have the rocket characteristics at least well controlled and defined you will be able to enter then into a firing solution, and hope to at least hit close to the target. But that requires you to have well controlled manufacture, and well controlled storage, and spend a few hundred hours with an airframe or three doing run after run at the same altitude, attitude and airspeed, to get the data. Then do it for all the different airspeeds to get a minimum and maximum envelope, and have some smart people sit and use this to get a set of equations you can enter into the firmware of the firing computer, and use it to get the firing solution. Once you have those equations as to distance for the projectile your firing computer is doing CCRP, every cycle it calculates how far the projectile will go if released now, and distance to target, updated from air data and INS/GNS, plus ground speed from the nav platform. Then as soon as the distance it will go is greater than distance to target, it will fire. Biggest error is that you typically also have to allow time for the system to fire them, so high rates of change of attitude mean a large error in distance to go, which can mean that, if the pilot sends the release command while pulling up,. they can be too close, and they will shoot way off target, or if he does a sharp correction the same. Plus you can also fly into your own weapon as well, seen those photos of the bomb that released, but also clobbered the airframe as well.

I will say though they are very strong and safe vehicles. Where i used to live one got t boned by a Fiat Uno, which was skipping a red light, and hit the Porsche (less than a week old as well, under 200km on the clock) on the driver door, and punted it 80m down the other road. Uno was basically crushed back to the firewall, and the cabin itself was compressed and buckled as well. Porsche though, all 14 airbags deployed, car was bent front and rear and looked like a banana, but the driver just had powder burns, and a bruise from the side impact airbags, and was otherwise fine. But the thing was that, despite being hit on the driver's door, and having a massive dent in the door, the cabin was still intact, only slightly warped, and that door both was still openable, albeit with bent metal impeding you, but also still would close and latch properly again. Uno driver had to be cut out of the vehicle. Both written off. Uno driver left in ambulance with police escort, and Porsche driver left with a friend who picked them up. both left on lowbeds, one because there was no way it would tow, and the other because all wheel drive, and towing companies not wanting to get the bill for the extra damages from incorrect tow.

SAE tooling for that banjo bolt because they are still an imperial thread, and you will never be able to change that, as it is a 1/4 inch pipe fitting. Just remember your caliper bolts, brake fitting threads and all hydraulic fittings are a metric equivalent fitting, because the old stuff was changed to nearest size.
2.5 and 4mm hex keys, very common in industrial machinery, though I will tell you that, if they do get seized fast, the easiest way to get them out is to have a few of those ultra cheap 30 piece 1/4in hex driver sets, and look for the Torx bit that will just not fit in, and tap it into the damaged hex head, so you can turn it out. Will get it out, and if you do not have a replacement capscrew, you can put it back in again with it, and wriggle it with a pair of pliers to get the bit out, making it into a Torx head.
Done that very often, because you might need that machine to run right there and then, and driving to get a new one, adding an extra hour of breakdown time, is often not an option. Make a note to keep that size as spare parts, for the next visit. I go through a lot of those size, M4 and M5, as they are a common thread, and you find often the stainless steel will gall fast to the aluminium parts if you do not use a thread sealer on them, especially if they get hot. I also have the thread repair kits for those sizes in various lengths, and the extractors for the broken screws, though you really burn through cobalt drill bits doing that, especially for the 8.8 high strength variant, and the left hand thread version drill bits are stupid expensive, even in plain HSS.
Ridgid do make a really nice extractor set, but sadly the lifetime warranty does not apply by me, so I have had to buy some replacement sets along the way, because I always break the smaller sizes.
