  1. For anyone wondering, all Intel x86 CPUs, even the original 8086/8088, use microcode. The ability to update it was introduced with the P6 architecture (Pentium Pro/II/III) which is coincidentally the oldest CUPs supported by stock Debian.

  2. Dave, I went to check this feature but it seems it isn't in my version of Windows 10. When you do more of these, it would be nice if you stated the Windows versions which are applicable. I don't mind you giving out 11-only tips but please let us know if this is the case.

  3. The start of their statement is obviously supposed to be BS but you need to give them some credit on the basis of technicality. This does protect their customer's data because they no longer collect it.

  4. It's nice when you have the schematic for something, but even nicer when you fully understand it and know exactly what each part does and why that's useful.

  5. Once you get the hack figured out, put a reed switch in the button and wire it in series with the signal. Then it will work normally for your kids but if you have a magnet hiding in your hand you will magically be better than them. They'd "never" know.

  6. 15:15 "Perhaps if everyone had come together and standardized on an interchange format things would have turned out differently." That actually happened with XMPP. The Google, AIM, Facebook, and MS Messenger services each supported this standard protocol. Unfortunately for us they closed back up. Now e-mail is all we have left in terms of commonly-used open-spec messaging.

  7.  @MrLunithy  You can often find leaked schematics for modern computers. While there's a ton going on it's actually pretty easy to understand if you only look at one piece at a time. When chips are as complicated as they are now they don't need much support circuitry other than power supplies.

  8.  @andymerrett  A battery-powered ignitor would need battery replacement and a physical or piezo ignitor is is much more annoying. As almost every stove has an electric (or electronic) clock built in there's no reason not to use the same electricity for lighting the stove.

  9. I'd argue a red hot knife isn't cool at all, in fact it's the opposite.

  10. Even though Noctua has rubber on the corners the screws thread directly into the main plastic body. That doesn't really stop vibration transfer but the stretchy mounting "pins" do. So unless I'm not mistaken the built-in isolators only work if the fan is held in without screws, like maybe the spring clips found on some tower CPU coolers.

  11. I'm curious, does that yes/no patch actually work? If it was just changing identifiers in the code it wouldn't change how it runs but since it also changes text strings some things might break.

  14. One tip with single-color strips is to feed positive on one end of the strip and negative on the other. This results in equal voltage drop on each LED and eliminates the brightness gradient which may normally occur.
    25
  15. There are already systems which do most of this. On a recent series of This Old House they installed a Mitsubuishi system which does home heating/cooling and water heating.

  16. Two things: 1. He wasn't making any real connections in his panel (as far as I know) 2. His electrical panel will be covered by the electrical code. Things like this aren't covered by electrical code. 3. IMHO products which, if used in the logical way, create hazardous situations should have prominent warnings. The instructions with this module should have been better (but that's not a real excuse). 4. Fuses, circuit breakers, and personal protective equipment exist for a reason.

  17.  @fufurabumbacka  Are you serious? Only a tiny portion of plastics are directly bought by consumers. Most of it is in single-use packaging provided by the manufacturers of things we buy. Try getting medicine without a plastic bottle.

  18. Even if you can order without bezel or keyboard I still think it would be better to have them included in the base price. Then there'd be a discount when you remove them from the order.

  19.  @semicollins  The recent calculator Minecraft we're all talking about isn't actually for the TI-84, it's for the TI-84 CE_. The CE has an eZ80 CPU which while compatible is _much faster than the Z80, about three times faster for the same clock speed. And the CE is 40MHz compared to the 15MHz of the non-color version so there's an 8x difference there. The eZ80 also has a true 24-bit addressing which makes large RAM things like this much faster depending on access patterns.

  25.  @waycoolscootaloo  The NEC only requires two circuits for kitchen appliances and the dining room needs its own circuit. Until recently the dining room circuit could be shared with the kitchen so the OP's probably was code compliant when installed. Having said that, code compliant doesn't mean well-designed.

  26. If we're talking about SanDisk, have you ever noticed their old (pre-2007) logo has sun rays? What's up with that? Answer: they used to be called SunDisk.
    12
  27. @elfrjz It doesn't make sense because Debian 6 (Squeeze) dropped support for the 486. Debian 9 (Stretch) dropped 586 support and that version's last LTS release was over a year ago. As I said, you need a Pentium Pro, Pentium II, or compatible CPU to run Debian at all.

  30.  @safffff1000  I watched another video about the Aptera a few months ago (maybe Rich Rebuilds) and IIRC in crash testing it beat all production vehicles. It turns out "organic" shapes are super strong. Besides that, SUVs and pick up trucks don't do too well in crashes, and more importantly they're easier to crash than regular cars. The reason there are so many of them is because they are excluded from many safety and emissions regulations.

  31.  @xeridea  You can't launch Task manager from the logon screen because that would let you bypass nearly all the system's security measures.

  32. Central air conditioning US homes with gas heat is installed in exactly the same way. For plenty of people with this setup a conversion to hybrid heat pump should be fairly cheap with only a few valves and a new controller.

  33. Or don't interpolate on the time axis. Instead of stretching each sample 9 times to reach 48000Hz sampling just output a WAV file with 5333Hz sampling. Then all the interpolation needed for playback is done by the audio software. Audio files with crazy weird sample rates still play back fine on modern systems.

  38. You used to be able to decide where midroll ads would appear. From what I've heard that option is now gone, or at least more limited.

  39. I'm no expert but I thought that non-VRF multihead systems run each head at the same relative capacity. If one room has high load the other area will cycle on and off (like a traditional system) to achieve the needed distribution. Is this not the case? Also, as somebody who has never actually worked with this stuff, I think hydronic systems are better for zoning than VRF. Run one loop at 120F and one at 50F. A zone will open valves to send the required temperature water into its coil and modulation is achieved by varying fan speed. It seems like there's much less that can go wrong compared to VRF, for instance a water leak in one area can be isolated for repair but a refrigerant leak would take out the entire building's heat.

  40. To add to this, there was a WM_PAINTICON message which the system sends to the window to ask it to draw this icon. The default handler draws the class icon but it was also possible to override this and generate an icon on the fly. I think Windows 95 might send this message and if it detects custom processing then scale down the drawn image to fit the taskbar and title bar icons.

  41. As am American who has read a fair bit of the NEC, the wire colors do have mandatory meaning. However, this is only code. Real life examples may be done using improper coloring (an innocent example is neglecting to remark the neutral into a live on a switch loop). Another issue is that this only applies to fixed wiring. AFAIK appliances can use totally different colors internally like this switch module does. The meanings are as follows: Bare, green, or green/yellow (the latter to halfheartedly harmonize with the rest of the world) is "grounding" aka ground/earth. White or gray is "grounded" aka neutral. Any other color is ungrounded aka live or switched live.

  42.  @israelgaribay9216  You want the passenger compartment to be as rigid as possible. I remember hearing the Aptera was exceptionally safe in crashes, they must have crumple zones figured out.

  43. Rather than hardwiring it I'd install a generator-style inlet panel. It can either connect to a matching outlet on the house or to a portable generator if ever needed.

  45. Built-in Wi-Fi won't work as well as a dedicated AP but more importantly very few chipsets work properly in FreeBSD in AP mode.

  46. I'm honestly most concerned with the auto-saving Notepad. If it auto-saves to the original files it will be very bad. If it saves to a temporary file it's not too bad but I also don't like the idea of actual user data being copied to hidden locations. I sometimes make temporary changes I specifically do not want saved.

  47.  @stephenhunter70  Are you asking? The login screen runs as SYSTEM so if you get task manager you can easily launch a full privilege command prompt. The end task function could also be used to stop services, or the process list can reveal incriminating information.

  48. I love your visual example, specifically the iPhone section. I also noticed your boombox appears to also be a TV. I tried using some smart TV apps on a 1940s TV (coincidentally also an Emerson) and ran into some slight issues.

  49.  @harriettanthony7352  Don't forget that most electric cars still need oil and coolant changes, just much less frequently.

  50. Well there wouldn't be a problem if you had them all on the same circuit. The only way it would be unsafe is if the current rating of a wire is less than the circuit rating AND the maximum potential load on the wire is greater than its current rating. If each appliance is plugged directly into the wall it should all be safe.

  51. I've only ever heard of those being used in RVs.

  52.  @criticalevent  You're right that most electric vehicles can't be used for vehicle to grid but hopefully that gets improved over time. You're right that when you leave home your car can't power your home but that's literally what the grid is for. Other people's storage systems would help power your house during that time and if you plug in at your destination you could power your house using the grid as an interconnect. As for inverter gear, it's not $20000. A Sol-ark is $7000 and there are plenty of cheaper options. The permits needed aren't that special, they are the same as you'd need for grid-tie solar. Even if they don't let you feed back to the grid you can still use the energy to power your own house. I agree an EV with a discharged battery goes 0km. That's why you set discharge limits so you still maintain enough range for what you need to do.
    6
  53.  @criticalevent  First of all I don't like Elon Musk bullshit either. But saying you can't grid-tie storage systems anywhere in the US is simply false. I live in Massachusetts where you definitely can, and there are incentive programs (ConnectedSolutions) for doing so. In times of grid overload they do pay more for kWh then you paid to charge the battery. They can afford to do this because wholesale electricity prices are highly variable. Today (3/26/2022) in New England wholesale electricity was $49.43 at 12:00 and $91.28 at 1:00. As for getting a permit for a 100kWh grid tie storage unit on an extension cord in a driveway does sound a bit ridiculous. 30 years ago you would think the same of people saying anybody could create home videos and anybody anywhere in the world could watch them without the creator or the viewer needing to pay for the service. Today it's obviously feasible as anybody who watches YouTube would know. The 100kWh storage unit in the driveway looks more sane when you consider that the energy capacity probably wouldn't matter, only the actual power. Saying you have a portable 5kW inverter seems much more reasonable.

  54.  @blechtic  That's a very good point. NOP (no operation) is an instruction on almost all CPUs. YESP probably isn't a valid instruction.

  55.  @elclippo4182  As played back the sample rate is 5333 Hz (it was output as 48kHz after a stretch factor of 9). In terms of bit depth it's better than 8 bits assuming the screenshot was more than 256px tall.

  56.  @joelimbergamo639  Most commercially available hydrogen gas is "blue" hydrogen, being a byproduct of fossil fuel production. "Green" hydrogen created from electrolysis is more expensive. The big downside of green hydrogen is once you take electricity, use it to produce hydrogen, and use a fuel cell to get electricity back out you have lost most of the energy. Batteries are just much more efficient.

  57. I'm guilty of that, let me explain a bit: 1. I'm lazy, that should be enough already. 2. I want my things to stay protected. The protective film does that. 3. Removing it is even more satisfying once the film is all marred. It's like getting it brand new all over again. 4. There's a risk I might damage something when removing the film. Sometimes it's unclear if a layer is supposed to come off or not. 4. I'm lazy. I didn't even renumber this point when I added one above it. I should say though, if the film gets in the way I will remove it. I'm not that crazy.

  58. 3-cell NiCd or NiMH used to be relatively common on older laptops. They (supposedly) can provide enough power to keep your RAM active while you swap batteries. I've never seen this feature actually work (maybe because those batteries are old AF now) and they have the downside that they can leak and cause damage.
    6
  59.  @jasonreed7522  The ground wire isn't zero because R is tiny, it's zero because I is tiny. That's the only difference between ground and neutral, neutral carries current while ground doesn't. If a neutral wire breaks it will rise to 120v and this is why the ground wire is separate. And a bit more of a nitpicky thing, you can't ever use the neutral wire as a hot. In 240v applications you can put colored tape over the end of the white wire at which point it ceases to be a neutral wire.
    6
  60. CR and LF have different functions. The carriage return code resets the horizontal and the line feed code increments the vertical. And a bit related the delete (7F) code is all ones and (originally) does nothing. If you punched the wrong thing onto paper tape you could punch out the rest of the holes and the computer would ignore this.
    6
  61. My touch lamp is factory wired in this way using the same type of module. Red neutral, black live, white switched live. The insulation on the yellow wire doesn't matter because it goes to an exposed metal part of the lamp. The two little blue Y capacitors are providing the isolation for the sense wire.

  62.  @AelfricLake  Not every possible result, only hardcoded results for specific constant inputs given at compile time. It's of limited usefulness because most inputs won't be known at compile time.

  63.  @capturedflame  I'm unable to tell the difference between lights flickering 60Hz in phase and those running out of phase. Given that you used the phrase "fairy lights" you might live in 50Hz land where I'm sure the difference might be more apparent. Regarding using cheap light strings as main illumination, I'm not talking about deliberately doing it. Rather I'm mainly talking about the incidental illumination decorative lights cause in a dark area.

  64.  @Lizlodude  My guess for your magic socket is that it was originally wired as part of a multi-wire branch circuit where each half was fed from a separate breaker (possibly one of which was your garbage disposal one). If the outlet was replaced but the tab on the new one was not broken it would result in two breakers feeding the same outlet. This should trip both breakers instantly as they should be on opposite 120v legs, but they erroneously be on the same leg if the wiring was modified at some point. This would be dangerous because the single neutral wire could then be tasked with carrying the current from two circuits. TLDR: A doubly-botched multi-wire branch circuit (MWBC) will only appear dead if two breakers are turned off at the same time. MWBCs are a great way to safely save on wire but can become unsafe if their breakers are moved around improperly.

  65. I think the electric motor is the future for main propulsion. Combustion engines will likely remain as range extension generators. AFAIK if you always run at one RPM and one torque many of the difficulties are eliminated.

  69. There was at least one case where somebody names their business after the fake place name that was already on the map. A second map company dutifully put it on their new map and were sued by the first map company. The first map company lost. Note: I read this somewhere, there may be some inaccuracies.

  70.  @MrKentaroMotoPI  That's the case with R22 which hasn't been installed in over a decade. Modern "Cold climate" certified heat pumps produce 70% of their rated output at 5F outdoor temp without aux heat.

  71. There's one brand (Mr. Cool) which produces DIY-capable mini-split heat pumps which don't require special tools. If they're legal in your area it's definitely worth checking out.

  73. Countersue. HTTP is not HTCPCP.
    5
  74. Ring circuits. When 32 amp breakers protect 20 amp wires there's the potential for things to go horribly wrong. If there's a break in the ring all of the current can go through one wire without tripping the breaker. Even if there's good ring continuity if all of the load is on one end of the circuit most of the current will go through that half.

  77.  @zack9912000  R32 is not highly flammable, it's classified as mildly flammable. It can occasionally burn in the presence of a flame but it won't explode. And fun fact: the mixed refrigerant R410A is 50% R32. If you have 410A you already have R32. It's nothing new.
    5
  78.  @benholroyd5221  Yes, the mechanical power to move the air is much lower the slower you do it. If the furnace runs at half capacity the blower only needs 1/8 the power output (so 1/4 the total energy) to keep the unit from overheating. Most existing furnaces have PSC motors which are horribly inefficient at low speed, negating much of this benefit. On these motors AFAIK the CFM/watt remains constant so the total electrical kWh on a given blower is the same regardless of gas firing rate. This PSC inefficiency is mostly a moot point because in the past 3-5 years all new furnaces have ECM blowers without this efficiency drop. So if you are getting a new system a 2-stage furnace will save electricity compared to a 1-stage one.

  79. I totally am with you. Unfortunately somebody I live with disagrees. My internal compromise is only keeping an amount I think I might need in any single project, I can always replenish after. I might want to build some nice furniture out of cardboard sometime.

  82. Definitely add extra grounding wires. Since some of the frame is held together with glue instead of direct metal on metal there might be breaks in his bonding.

  83. Over time it doesn't matter but in the (very) short term it does. If there's very poor heat transfer there will be a delay before it heats the room.

  84.  @IkBenBenG  I've never heard of pinball machines between full EM and near all electronically controlled. The ones I've seen worked on on from the late 70s use a switch matrix going to the MPU and most coils and controlled lamps are directly run from a driver board. A few coils like flippers and pop bumpers might be run by switches but all the logic is done electronically.

  85. If you don't want to buy multiple drives you can just use use multiple partitions on one, which should be good enough for separation purposes. If you're running spinning disks you can also get better performance by putting your OS and commonly used programs on a smaller partition at the start of the disk.
    5
  86. Definitely try different panel technologies. Old TN panels are usually white when unpowered and AFAIK this means there's a good chance both polarizers are in the same direction. This would mean they can be stacked without interference. The efficiency would also be much higher this way.

  87. I don't buy your laptop. The original Core Duo is only 17 years old. I'm typing this on a 10-year old i3 craptop. And I'm working on a 15 year old Core 2 Duo laptop. I know it was a joke but whatever.
    5
  88. I feel much the same. Gas engines are generally 35% efficient at the high end so whole house generators are going to be fairly worse, totally tanking at lower load levels. And most of the time they will run at these lower load levels. I'd guesstimate the generator would be running at around 20% efficiency, meaning you'd need a heat pump COP of 5 to be a more efficient use of gas. Directing the hot air coming off the generator into the cold air intake of the heat pump would probably work reasonably well to boost the system efficiency. AFAIK most whole house generators are air cooled so it would be hard to use their waste heat directly. If you have a water-cooled generator it would theoretically be easier as you could use the engine as a boiler in a hydronic heating system. This is such a good idea automakers have been using this for cabin heating in ICE cars for ages.
    5
  89. And adding a heat pump is just about the same as adding a cooling-only unit. The main difference is in the thermostat wiring.

  90. The way I see it the act of recording logically has no place in such a law if the purpose is to prevent disruptions in official interactions. Somebody 6ft away without an active camera would interfere the same amount as somebody recording.

  91. This is a good test for hot water systems (and also increases boiler efficiency) but it doesn't work for forced air furnaces. Furnaces output a fixed amount of heat regardless of the output temperature.

  92. It sounds like that stirring of molten metal is "just" a bog-standard induction motor.

  93. IMO direct linkage of steering and braking is more important. Electronic throttle body cause too much harm when the brakes can overpower the engine and you can kill the ignition power.

  94.  @realtimberstalker  The monitor is communicating its size, it's part of the base EDID spec which has been used since the nineties. Ever notice how Windows 10 chooses different default scaling factors on different density displays? Having said all that, I very much doubt MS would enforce a minimum screen size. At most they'd just throw up a warning.
    4
  95.  @YodaWhat  I doubt it's emitting X-rays. The voltage on the primary is fairly low (certainly under 10kV) and it's a step-down transformer with only one turn on the secondary. The voltage if it was an open coil would thus be under 2-3kV, and X-rays that soft would be completely blocked by the glass. But it's not an open circuit, it's a shorted coil. I believe this means the voltage is essentially zero. Then there's the bit where you need a hard vacuum to generate X-rays from electricity. I probably should have started with that. AFAIK the only EM emissions from the plasma will be from the spectral lines of the xenon.

  101.  veevyo  When I got my calculator the color ones had just come out and the new 84SE was probably around $140 as well. The rechargeable battery in the color model is also a curse because it doesn't last as long. I ran my mono model with 3 rechargeable AAAs (and a paper clip in the fourth slot) for several months between recharging. More recently I did in fact use a Li-ion battery. I'm not saying you didn't get a good deal. It's just fun to sometimes 1-up another person.

  102. @weetwteqtwtwwt The inability to heat without electricity is already a problem with 99% of existing gas heat installations. Relying on heat pumps won't change that at all.

  103. You only need a crossover cable if neither end supports auto switching or auto-MDIX. Almost all gigabit devices support this as do most FE interfaces in the past 15-20 years.

  104. If Xcode has a memory leak closing it and reopening should fix it unless there's something I'm missing. Worst case logging off and logging back in would probably help if there are background components you can't normally close. If rebooting was the only fix for a memory leak it must be an OS fault.

  108. They used to ask you on every single question but that can get really annoying. By saving the errors it can say something like "there are 39 other files you're copying which have the same name." That's useful information before saying 'yes to all' or 'no to all'. At least that's my guess why they wait until the end.

  110. Finally somebody with the same thought as me. The write-protect only applies to part of the chip so it's still possible to update the firmware, however the protected part verifies the writable part. In essence it's the same as what AMD is doing here except the protected keys are kept externally instead of internally.

  122. The thing about a furnace fan motor is that it's one of the most generic parts. I keep a spare blower motor at home after the old one failed. If the current one fails, or even if we get a new furnace and its blower fails, I can quickly restore basic functionality. I hope to upgrade the system to dual-fuel and this will heave with a backup against any single failure. Even if the furnace control board dies I'd be able to hardwire the motor on and use the heat pump.

  123. All the US light switches I've seen are rated for at least 15 amps. Maybe not really old ones but the cheapo sub-$1 ones at the store are certainly rated 15 amps. Whether or not it's wise to run them at 15 amps is another matter.

  124.  @wojtek-33  That problem could be overcome by reading (in addition to education).

  131. COM files are headerless, they just contain real mode code which is loaded directly into one segment of memory and executed. Since each 16-bit segment is limited to 64 kilobytes, COM files can't be used for larger programs. DOS (MZ) exe files have a header which lets DOS load more data into memory. Win16 (NE) and Win32 (PE) exe files contain all the segment information, import tables, and resources you need for a Windows program; COM files are only for DOS (and CP/M IIRC).

A long time ago (probably 15 years ago, but less than 20) I picked up a used (and then very outdated) book "Linux: Configuration and Installation (First edition) which described how to set up Slackware 2.2. I didn't know until literally today but it was written (partially) by Slackware's creator. Unfortunately it was missing the CD. If I can find an ISO of this disc it might be neat to do a "retro" install of what Linux was like back in 1995.

  151.  @Luke357  I don't believe you about your laptop charger. 5 amps at 120 volts would be 600 watts so it would be burning up with that much power. 5 amps output is reasonable when your laptop is working hard and/or charging at full speed but that's at only 20 volts. Average load of 10 amps would mean (assuming 240v service) 12,024 kWh/year (or 1,1752 kWh/month). EIA says average American hosehold is only 10,500 kWh per year.

Basically they'd need to remember the video and then endure the fart spray to get the phones out, but then the phones will still be locked and tracking them. To get the phones usable they'd need to bypass the reset protection and then change the IMEI to one which isn't blacklisted. While it's certainly possible to get the phones usable it is well outside the capabilities of most tech enthusiasts, let alone random porch thieves.

Ideally for heating you'd be using an electronically-controlled heat pump which could sense and automatically throttle its output to avoid exceeding your service. This technology is pretty common for EVSEs at least in the UK (where I do not live) and there's no reason it can't be on heating as well.

If you look at the downloads page for the latest Poweredge R740 you'll find the Matrox Video Driver, currently at version 4.4.1.3 released on 09 Dec 2019. It has Dell's driver ID 1dvtp and you can see the huge list of servers it is used with.

I think calling the multimeter a voltmeter was an honest mistake (after all most of the time it is used as a voltmeter), and I think it's fine to refer to the low voltage system as 12 volts. That's the nominal voltage, literally meaning that's what it's called. While it is usually greater than 12 volts it can also be less than 12 volts. It depends on the battery's state of charge.

  192. It doesn't matter if we use HDMI or not, it only matters if the ports are present. And I had the same thought about shipping less expensive HDMI-less models. I suppose as the chip provider they could ship all future GPUs without HDMI and card manufacturers could add an onboard bridge chip if desired. And while they can't have an "HDMI" port without paying the forum I believe they could have unbranded 19-pin TMDS video connectors which happen to be compatible with HDMI displays, at least for standard 1080p.

As a mechanical thermostat cuts power to the entire refrigeration circuit you can also stall the compressor just by adjusting the temperature. Electronically controlled fridges probably all have built-in timers to ensure this doesn't happen.

  196.  @MaxDad7  For business desktops power efficiency doesn't really matter. What matters is power consumption per unit which hasn't changed much since Haswell. An old M93p Tiny uses under 20 Watts most of the time. Plus the employees to use those systems cost much more than the electricity so unless the computer is hindering productivity there's no reason to upgrade. Even if each new system is 10x as powerful you still need one desktop per user. In the datacenter where more powerful hardware means you can consolidate and use fewer servers the situation is very different.

  197. ​ @Pugjamin  I don't know most of the details but for the McLaren I believe they need a particular model of Compaq laptop because they have hardware which connects using a proprietary interface on the laptop. If it was as simple as running software in a VM they would already be doing it. The McLaren is an interesting yet slightly atypical example. In nearly all of these legacy systems it's specialized hardware which prevents easy upgrading.

  200.  @Tkaya460  Compared to furnace+AC it's not much more install cost. If the heat pump is consistently more expensive to operate at any temperature then use the furnace for 100% of your heating and leave the HP for cooling only. If utility rates change you can start using the HP when it's warmer out. Or if the furnace has a malfunction you can use the HP to stay warm. If you live somewhere where electricity is 10x more (as you claim) and it never gets hot then sure, go with a heating-only furnace.

  201. I'm sure they would have used a single fixed head if they could have. They didn't have modern magnetic coatings so they needed greater speed. And they didn't have digital processing so it would be impractical to split one high-bandwidth signal onto multiple lower-bandwidth tracks. You also couldn't just change tracks at the end of a tape because that requires changing the direction of travel. This transition takes time during which you would lose signal. Again with digital technology it's not a problem, for a realtime analog system it's unacceptable. While a spinning head drum has its difficulties, it's not as bad as you suggest. The synchronization needed is just a simple PLL. You only need two heads on a helical scan system (or only one if it doesn't need to be compatible with standard TV) and they can be coupled with rotary transformers for increased reliability and signal integrity compared to old-school brushes.

  202.  @aawillma  A 2 stage furnace runs the blower at reduced speed when heating slowly so the electrical demand does scale. If you have an older PSC motor the efficiency drops off at low speed, ending up with slightly increased electrical kWh per Btu out. If you have a new ECM blower things are totally different: a slight reduction in blower speed results in a massive drop in electrical consumption. Halving the airflow results in 1/8 the power.

  205. A heating pad is usually sixty watts, well under the 1000w continuous that a light-duty extension cord is capable of. So I'm sure chaining cords wasn't the cause of the incident. Having said that, it's still not a good idea to do that. The cause of the damaged outlet was almost surely from arcing due to a loose connection at that location. If there's a decent amount of current flowing arcs can leave quite a bit of damage. Due to the way outlets are daisy chained a load on one outlet could smoke a different outlet on the same circuit.

  206.  @yifeiren8004  It's a neat feature and shows attention to detail but the lack of an auto-rotating display does not translate to a lack of respect to customers. Other factors, such as the presence or absence of necessary features are much more important.

  208. I think compatibility was the main reason, but not necessarily how you might think. The 9x architecture allows you to reuse 16 bit drivers and other programs which directly access hardware. Win9x also has lower system requirements but by Win98 this wasn't really an issue.

There are some considerations such as making sure the charge voltage isn't too high and that some BMSes don't like you putting 12v batteries in series. For extra runtime, just duplicate the age-old hack of running wires out of the unit and attaching larger batteries.

  214. One slight correction: gas stoves in the US don't have safeties. While they won't automatically light in a power outage they can be lit with a match. Gas ovens are as you describe. Almost all* have digital controls and electric gas valves. *Somehow I ended up with an exception. This oddball oven has an intermittent pilot. When you turn the knob it mechanically opens the first valve and the spark unit lights the pilot. From that point it works like a traditional standing pilot system (with a thermal safety valve). Once the oven knob is turned back to OFF the pilot is turned off. If the intermittent pilot it lit by hand it can be started and used 100% without an electrical connection.

  217.  @harshnemesis  What do you mean? Turning on floor lamps from the entrance to a room is useful anytime you want easy access to light. It's literally the reason we have light switches instead of switches at the light socket. Keep the lamp's own switch on all the time and it's easy.

  218.  @aussiegruber86  That's exactly what oil heat is. Oil is pumped through a nozzle and burned.

  219. CF also has some additional capabilities beyond PCMCIA. And with COM files, yes you can put data past the code boundary. DOS will load the first 64k into RAM (I guess actually 64k minus 256 bytes) and you can load more yourself if desired. Many EXE files like self-extracting archives work in a similar way.
    3
  220. Part of why PCI has burst mode but ISA doesn't is because PCI multiplexes the address and data lines. With ISA all the lines are available at once so you can read a random address every cycle. With a multiplexed design like PCI you need at least one extra cycle to transfer the address before you transfer data.

  221.  @MusicByproduct  Temperature is one of the factors in degradation. if you charge regular batteries at high C rates they heat up, accelerating their demise. In modern EVs the cells are liquid cooled and sometimes also connected to the air conditioning system.

  222.  @nextleveljoe  The whole point of a patch panel is that it keeps the solid-core in-building wiring secure and free from damage. Troubleshooting may be a bit easier directly terminating to devices but I don't want to be the one running a new cable when I could have replaced a patch cable.

  223.  @thingsiplay  The vast majority of Bluetooth adapters used in PCs are electrically connected over USB. I'm not talking about rectangular type A connectors but special internal connectors. These are the internal ports option 2 will automatically authorize. One example is the A/E key M.2 slot used in laptops for Wi-Fi/BT.

  224. Actually our basic 100 amp service is 24 kilowatts because it's split phase 120/240 instead of straight 120. And that's the minimum for new construction, where I am 200 amps is the norm. We don't use nearly that much but I don't see how 2.5 kilowatts is livable unless you only have lights and small electronics. Wouldn't an electric kettle and a refrigerator bring you right to that limit?

  225. I've been looking at making my own solar battery backup system. Here in Massachusetts we have incentives to use our battery storage to help stabilize the grid so it becomes worthwhile to get a large system. I'm looking for at least 30 kWh for this reason and as a nice side effect it would be able to provide power to the whole house for an entire day even without sunlight.

  226.  @lirawyn  The colors are indeed correct for regular single-phase 120v outlets (NEMA 5 plug). However, this is a 240v device with two hots and no neutral (NEMA 6 plug).
    3
  227.  @ohrosberg  I believe heat pump systems like yours in Europe are cheaper because they're more common there. In the US anything other than a mini-split is relatively exotic and carries a cost premium. Energy prices are also generally lower in the US so combined with lack of consumer education there's just not as much demand.

  228. Temperature compensation could work but do you know what would work even better for ensuring consistent light output? A photoresistor. I bet the circuitry found in $2 light sensing incandescent nightlights would work pretty well with minimal adaptation.

  229. Cloudflare usually needs to be your domain's main DNS server. So to switch to something else you need to update your records in the top-level domain servers which will take hours to propagate. It's not really practical to do automatically.

  230.  @ps.2  I didn't say it's a good idea, just that it would be better. A hybrid approach would likely be best, with dedicated magnetic connectors which interlock and provide tight field coupling. This is more or less like what GM's EV1 used.
    2
  231.  @markvalery8632  Exactly. You would be paid $0 and the power plants would also be paid nothing. The distribution company (assuming it's separate from the generation company) could get a bit of payment because their infrastructure is responsible for moving all the energy around.
    2
  232. It depends on where you live. It varies based on cost of electricity vs fuel as well as the temperatures you encounter. AFAIK in most of the US heat pumps are less expensive to run than furnaces.

  233. The EM fields coming off the compressor are minimal.

  234. At least yours has matching symbols. On mine the labels for the alternate keys don't match the actual functions. For example the label for scroll lock is on Page Up but the real combo is Fn+Delete. And Delete is labelled with insert as its alternate function, even though insert has its own key.
    2
  235.  @Dargonhuman  The manufacturer has a keyboard driver on their website which I didn't install. I didn't see why it would be useful since the OS itself has perfectly good keyboard drivers. That was before trying those Fn-key combos. Now I figure the driver remaps the keys in software to match their labels. But now I'm used to it so I won't bother with the special driver.

  236.  @BThings  The big issue is that plenty of people have looked at this coupling of antifeatures (largely due to one specific company) and have falsely equated that with EVs in general.
    2
  237.  @pilotavery  Not quite. SD and SDHC use different protocols. A 4GB+ SDHC card is not recognized as storage at all by legacy SD-only devices. It's not like hard drives where you can use large drives as small ones.

  238. Not necessarily. When you change the password the system has the plaintext password in RAM, at which point it could easily check against previously stored salted hashes.

  239. I think the information should definitely be available even though not everybody should be doing the repairs. In a similar manner not everybody should be performing surgery. How do you ensure you choose a qualified surgeon?

  240. I believe that's not actually the case. NUT alters the shutdown sequence so the service stays running even after all the filesystems are fully unmounted. If the server is still receiving power it's able to send the shutdown command.
    2
  241.  @lunlunnnnn  I would argue there's no need for new code ranges, even if you need more than 99 errors of each type. 499 could be defined as client error/other and an additional header could provide an extended code.
    2
  242. Smaller heat pumps are generally more efficient, and multi-head ones are less efficient. Assuming it's all properly sized your setup with entirely separate units is actually the most efficient. To answer your question, the "dehumidify" function will adjust the parameters so the indoor coil is colder and airflow is lower. This results in more moisture removal, but less efficient operation.
    2
  243.  @emrahdincer  Because sometimes you need more heating/cooling in one place, especially with an open floor plan. It's also easier (and cheaper) to install one moderately sized unit instead of several tiny ones. That means a lot.

  244. Simple. That person shouldn't get a full BEV. A plug-in hybrid may be more appropriate.

  248. ON the old family Win95 PC there was an old "MS-DOS Application" of unknown purpose but we kept it because it was probably there for a reason, even though it would just crash if you ran it. Relatively recently I went back and decided to investigate what it was. I opened it up in Notepad to look for any identifying strings and noticed a telltale "BM" magic string at the beginning. It opened up perfectly in Paint and it turns out a much-younger me was trying to create a website or something. Not knowing anything about how any of it worked, I had made a BMP file but with a COM extension.

  250.  @bobprivate8575  You're pretty close. A regular cheapo 120mm fan from my box of extra fans (Yate Loon D12SH-12) is rated at 0.3A (still not much) and the fan from a BTX Dell is rated 1.4A. Drives are also a bit more. Spinup power is more like 30W (actually less than you said) but idle power can be a bit over 7W and in use power is close to 12W. As you said, this still isn't going to be a huge issue. Good PSUs can handle a bit of overload for a while, there's sometimes even a listed spec for this. An old prebuilt I have has a 12V rail rated 4A continuous or 7A for 15 seconds maximum. I wonder why we don't see ratings like that on modern PSUs.
    2
  251.  @railgap  If you want a white LED lantern with copious light output and crazy runtime then don't be afraid to look at something that's not fancy. During power failures I have used a combination of 12v lead acid battery, power inverter, and standard 120v LED bulb to get plenty of light. The weight and clunkiness of this make it somewhat impractical for camping but it's great for emergency lighting. Having said this keeping a fuel lantern with super easy repairability is still good to have, in case the LED solution breaks or you need something with longer runtime.
    2
  252. Yeah, I've done a 2015? MBP battery and this new one just looks so much easier. Sure you need to take out the motherboard but I'd rather do that than try to pry out a "spicy pillow".

  253. Maybe older versions were different but in XP I definitely remember when opening an EXE it would ask if you wanted to extract all the other files as well.

  254.  @radiotec76  Your bulbs likely are using switchers. The majority may be linear but I'd guess ~25% are switchers. Side note the circuits used in CFLs are quite different than regular switchmode supplies. They are much simpler, only using two transistors and little else.
    2
  255.  @Sha.ll0w  A stove ignitor normally using grid power but having batteries for backup ends up being a terrible solution. When you have power the batteries sit and sit, likely leaking and causing damage. Then when the power's out it's still no good. It would work if you regularly check the batteries but nobody will do that. If somebody is willing and able to change the backup batteries chances are they can handle some matches. Also the circuitry needed to seamlessly support both is much more complicated than only dealing with a single power source.

  256.  @KyouTGD  Furnaces need fans but basic gas fireplaces do not. There are also some very old gas room heaters still in use which don't use fans.

  258.  @WatchesTrainsAndRockets  Depending on how you define "security" being able to terminate your own processes could be considered a risk. They might want software like remote monitoring to stay running. As a (sometimes viable) workaround one may use a different program instead of Task Manager.
    2
  259.  @WatchesTrainsAndRockets  I agree remote monitoring should generally be done from a priveleged context but I've seen things run as the user so there must be some reason. IIRC services have limited access to desktop sessions so that might be part of the reason. But whatever. Regarding disabling task manager being useless, I more or less agree. The less agree part is because it can provide security through obscurity.
    2
  260.  @markm0000  Thermostats for (whole-house) heat-pump systems have built-in support for backup heat systems. It will work automatically and will maintain constant living temperature. As a plus smart thermostats can use other data to help make their decision, such as weather forecasts and realtime energy prices.
    2
  261. Basically yes, but with a big difference. The outer unit is going to be using a different refrigerant which works better in the cold. Also the units are tightly coupled instead of going to air and back. I don't think you were serious about doing that.
    2
  262. I'm pretty sure they sell brackets that prevent the "unplugged due to tripping on power cord" failure. However they increase the likelihood of the "outlet and plug totally destroyed due to tripping on cord" failure.

  264.  @IshayuG  MS-DOS only used local time and had no concept of time zones or UTC. To maintain compatibility when dual-booting legacy OS it made sense to keep the RTC set to local time. There hasn't been a good time to change this behavior. Actually the switch to UEFI would've been a good time to switch but it's too late for that now.

  265.  @TheNabeshein  Modern dishwashers have an exhaust fan? My mid-90s Maytag runs a fan during the dry part of the cycle. It's so not-modern it doesn't have any semiconductors.

  266. Here's one analogy: moving small a stack of papers one at a time takes longer than moving a single large book.

  267.  @markbooth3066  Fan laws dictate that it only takes 1/8 as much power to push air 1/2 as quickly. Even when you correct for increased runtime it's massively more efficient to blow more slowly. Rather it's massively more efficient if you have a brushless ECM blower. Simply turning down the blower speed of an older PSC motor results in an unchanged CFM/watt AFAIK.

  269. He's just doing it to cool off the air. I hope you saw his last video.
    2
  270. Hydronic systems are also an option. Have one central compressor heating/cooling a loop of water which goes to simple fan coil units. The thermal mass of the water means the compressor can cycle less often during low load situations. A water loop also enables in-floor heating which is usually more efficient.
    2
  271.  @rafflesmaos  If you have fan coils and in-floor heat you could configure it so the fan units are always contributing. That would mostly eliminate thermal lag. But I also need to ask, wouldn't insulation between the slab and the floor also eliminate this lag? Having said all this I would probably also have a small ducted system for air circulation and HRV/ERV.
    2
  272. Because then they would also be used for mining

  273. With a smaller system you wouldn't need as much airflow. This results in much quieter air ducts.

  274.  @Texan1048  Your Arris device is intended to be an access point, I'd expect it to work fine. The chipsets used in PC adapters don't work as well for access points. The max power level will be more limited and you will be limited to single-band operation when in AP mode. Not great for modern standards.

  275. A mileage (and weight) based road tax would be more fair than a fuel-based road tax, there are just many logistical problems for that to catch on.

  279. That would be a clear GPL violation.
    2
  280. You shouldn't even need a switch on the outlet. Unplugging the cord would provide the code required disconnect. And the way I interpret code an ordinary switch doesn't provide the required disconnect.
    2
  281.  @zncon  I also have a standard light switch there, and looking back at the electrical codebook I can't find anything saying you need a disconnect on a furnace. If you did then a regular switch would not be acceptable. If the switch is a shutdown required by fire codes then the light switch makes sense.

  282. The most difficult part is probably indexing. For a good index you literally need to go through every webpage on the Internet.

  284.  @sharkuel  I don't think it's possible for Ventoy to break a drive. My main problem with writing an image directly is that I don't want to dedicate an entire 32GB or larger drive just for 2GB of data, that just feels wasteful.
    2
  285.  @sharkuel  Ventoy just uses block devices normally. Unless your drive firmware does very strange things (which admittedly some do) Ventoy is no more likely to cause problems than any other application. I don't doubt that your drive broke when using Ventoy, I'm only suggesting that it wasn't because of Ventoy. Let's say a car broke down when driving on I-90. It's (almost certainly) not the highway's fault. If you happened to be on I-95 the car probably would have broken down there instead.
    2
  286.  @sharkuel  That just sounds like a failing drive. Long response times often precede total failure. What if a car was down on power and blowing out smoke for 20 minutes on the highway? Still not the road's fault.

  287.  @realtimberstalker  It operates based on pixel density. Windows will choose 125% on a 15 inch 1080p laptop and 150% on a 14 inch. Same number of pixels, different screen size.

  288. Their stupid mistake is calling it the "Restrict" act. IMO that's a super negative name. "Let's restrict your rights".

  289. All the components like the motor inverter will have capacitors on the input. As it's a three-phase output the current input will be very smooth so there will be minimal benefit to having super-oversized capacitors.

  291. There are a few instances where your public IP appears unblurred and a few more with your ISP gateway. But that doesn't matter because they change. P.S.: If you update a dynamic DNS entry with your public IP, don't publish that domain name if you want to keep that IP hidden.
    2
  292. I think the reason they didn't write protected mode drivers back then is because it would be too much work to write and test drivers for every possible type of hardware. By using the existing BIOS interfaces you ware saved from this work as every hardware manufacturer supported the interface. Protected mode drivers are only a practical choice if software companies and hardware companies can agree on an interface. Otherwise somebody writing a protected mode program would write their own drivers for popular hardware and likewise hardware manufacturers would only release drivers for popular software. The chances of uncommon software working with uncommon hardware would be low. This could be seen back in the day with Linux, for example. Basically every hardware company would release drivers for Windows because it presented a huge market share. If old versions of Windows lacked the ability to use real-mode BIOS interfaces it probably would not have become popular enough for everyone to support it.

  293. The fact that working on medical devices can be dangerous does not mean that repair information should be hidden. If I take something in to be fixed by someone else I still want to know what is going to be done so I am well-informed.
    2
  294.  @jimmyc1518  The Note 7 issues were because they made the cells without enough safety margin between layers in order to get the absolute most capacity possible in the smallest possible size. In cars nobody cares if the battery is two mm thicker so even if they used the exact same battery chemistry (and they don't) it would still be safer. Plenty of smaller brand EVs use LiFePO4 cells which are much more stable than the NMC used in brands like Tesla which itself is decently safer in operation than LCO normally used in smartphones. And if you think charging electric passenger cars charging will break the grid, please consider that most charging occurs at night when overall grid utilization is lowest. And if you need to wait in line to charge, you should get a way to charge at home. If fast charging takes 20 times as long as filling a fuel tank but people only need to use charging stations 5% of the time then the waiting would be equal to current gas stations assuming an equal number of charging stations. One of the largest practical barriers to EV adoption is that many people don't have their own dedicated parking spaces at home where they could charge.
    2
  295. I stay behind the times (I adopted 3rd gen i5 last year) and have played enough with old crap. You shouldn't need to worry about pump failure because thermal throttling works really well these days. I'm crazy enough to sometimes run without a CPU heatsink during testing and nothing bad has happened. Water cooling with a stalled pump is definitely going to be fine.
    2
  296. In my older setups I also used to disable lid sleep, partly because that's what I was used to from my Win98 and older laptops. It's easy to press a Fn-key combo every time when you want it to actually sleep but much more of a nuisance recovering from an unwanted sleep. I feel the need to ask you, why don't you use sleep instead of hibernate when you're making your wiring changes?
    2
  297. For off-grid (including grid failures) I believe almost all "Powerwalls" support frequency shifting which lets them safely charge directly from any AC-coupled generator. The main downside of this is that some AC-powered clocks will run fast.
    2
  298. Most filesystems don't actually have these special entries, it's emulated for compatibility reasons.
    2
  299. That happens with the most basic single-stage heat pumps. Modern tech has improved that. Georgia has a design temperature of 25F and at this temperature a modern "cold climate" heat pump will give full rated heat output at a COP of 2-2.5. So your $400-$500 heating bill using heat strips would be $200 with a better heat pump.
    2
  300. I think if installing an outlet you should go with a NEMA 14 and if designing a device you should aim to be NEMA 6 compatible. Since the only electrical difference is the neutral wire, you can safely and easily convert a NEMA 14 receptacle to a NEMA 6 receptacle, but the reverse is not true.
    2
  301. If your radiators don't put out enough heat with low temperature water you can add a fan to them. In the US the term for this is a fan coil unit (FCU). A fan blowing through an existing radiator would also work.

  303.  @TruthFiction  There could also be trailers which use fuel-based generators for range extension. When an engine can be designed to run at a single load and power level it can be made simpler and more efficient than a standard automotive engine. They could also use other technologies like fuel cells.

  304. Yes. An uncoiled 12AWG extension cord will always be protected by the circuit feeding it.

  309. The brilliant thing is that in a system like that the processor doesn't know anything about the memory map. The CPU has 16 pins which make up the address bus. A common setup might be to use a 74ls138 as chip select logic. It has 3 input pins which would be connected to the 3 highest address bits and has eight output pins, with each one triggering based on the input bits.

  310. @asdrubale bisanzio Albania, the Congo, Iceland, and Paraguay use basically 100% renewable electricity sources. So yes, it's more than possible to last a day or two without coal. Hydroelectricity is by far the main renewable source and it naturally provides storage. If you are insistent on the 'bad weather' excuse, consider that most days wind and solar does generate. This reduces the need for fossil fuels which can be saved for those bad weather days.

  311. Yes to Chrome versioning being stupid. Firefox only copied that to avoid looking outdated in comparison. USB I can't agree with the same way. They're only on version 4 and all of the major versions (possibly excepting 2) involved major PHY changes.

  312. I've been using a Wayland session on my T61p using the nouveau driver on the much more pathetic (by modern standards) Quadro FX 570M. I doubt you'd have any problems related to your choice of card but there's one way to be sure. Just try it and see if anything happens.

  313. If the wiring's already there you can install an appropriate 240v receptacle for under $100 in parts (a bit more if you need a new GFCI breaker) and less than an hour of electrician labor. Then get your own plug-in EVSE and take it with you when you move out.

  323. A possible idea for a crazy filesize optimization is pre-initializing the stack in the data segment and resetting the SP register at startup. You'd call RegisterClass and then increment SP by the needed amount to get the pre-computed stack frame for CreateWindow. But for an easier start I'd remove the useless call to GetCommandLine, switch from WNDCLASSEX to an old-school WNDCLASS, and move that into your data segment so you don't have so many MOV opcodes. And btw I am a subscriber but have my subs set to private. I can produce documentation corroborating my subscription status if required.

  325. It's LiFePO4 so it should last a long time, 10,000 cycles is normal for this chemistry. They mentioned a 10 year warranty so clearly the manufacturer expects it to last more than a decade. Also keep in mind it should keep working even after "end of life", just with reduced capacity.

  328.  @haxie4516  From the hardware's perspective they are the same. Everything that gets shut off for S5 can be shut off in S5 and everything that can stay on in S4 can also stay on in S5. If something is on in S4 but off in S5 that is only the result of software control. Can you name anything that actually is physically/electronically different between the modes? I would like to be proven wrong.
    2
  329.  @haxie4516  The defaults must be highly situational then. I've never seen anything wake from USB or PS2 in S4 mode and I honestly haven't looked that closely at LAN states. But it's definitely stupid for WoL to be enabled by default; the average user will never use it any anybody who will is technical enough to enable it.

  330.  @ClaytonDorris  Are you forced to use resistance heating as your home's main heat source? Are your light bulbs where you need heat? If you answered no to any of these questions then switching to incandescent light bulbs because of their heating effect is a poor idea. Even something as simple as ceiling mounted lights (where the heat stays above your head) is less effective at heating than electric heaters at the floor. The best way to use resistance heating is a radiant heater pointed at you. If managed properly this could be done with incandescent floodlights but I doubt your existing lights are designed to do this.

  332. The secret is we only have one phase going to residential areas. The second leg is an exact opposite (180 degree) instead of 120 degrees as if it were three phase. I hope this makes sense. In areas with true three phase, you indeed cannot get an entire 240v from two phases.

  339. When the car isn't active the entire HV system is disconnected for safety and efficiency. The 12v battery keeps everything working in the meantime. One of its main jobs is starting up the circuitry which enables the HV circuitry. Once the car is running the DC-DC converter supplies all the 12v current so the battery isn't being used. However the battery is still helpful at this point. It helps the converter deal with sudden changes in load and also is a backup in case the converter fails.

  343.  @cristiancristi9384  Authorized repair is rarely the way to go, and many earlier EVs had worse batteries. Of the big brands in the US the Leaf was the worst. Most EV batteries are bolt-together pieces. The hardest part of basic repairs is just wrestling with the sheer size of the units. Once it's open you can take a multimeter and go 3.8, 3.8, 3.8, 2.7, 3.8, which one is bad? As EVs become more common there will be more independent shops who will be experienced with this. Note I said independent shops, dealers will surely just quote an expensive whole pack replacement. The scary part is that some makes (like one that rhymes with Besla) are very consumer unfriendly and are reportedly making the batteries unreplaceable in newer models. I really don't like that company and I sincerely hope others don't go the same way.

It's probably more secure doing this than running everything in a UAC-limited Administrator. Still, I don't get the point of disabling UAC. Other than some severe annoyances if using network drives it doesn't hurt.

  360. Basically there's an embedded controller chip on the motherboard which is always running when standby power is present. The power button and power supply control line are connected to some I/O lines it has. It is also a device on the main CPU's bus. When the OS wants to power off it sends a certain value to the controller's data port, then the controller receives this and switches off the PSU.

Most people will spend more than that on an electrician to run power line and install the unit.

I'd argue electric coils are more dangerous because they're less visible. IMO the bigger problem with gas stoves is the lack of proper venting in 99% of installations. Pure natural gas is theoretically 100% clean burning but in practice using gas stoves results in a significant decrease in indoor air quality.

  370.  @seanplace8192  What makes you think the feeder is 8AWG? Ground and neutral was connected in the subpanel so it was originally installed decades before modern color-coded Romex. Btw 40 amps is only the maximum for 8AWG when 60 degree parts are used. If 75 degree parts are used it would be rated 50 amps. But regardless of the feeder, I agree the EVSE still needs to be reconfigured for 24 amps max because of the 10awg wire and 30 amp breaker.

  373. Given that the system fans came on we know the PSU was somewhat working. Manually jumping the enable line would also make it appear to work. Actually without the load of the system chances are it would work fine. You'd need to do some electrical tests to diagnose it. DC voltage checks would likely have caught the problem this time but to be sure a PSU is working well you need an oscilloscope to check for ripple or voltage abnormalities too quick for a multimeter to see.

This Old House installed one by Mitsubuishi in season 40. They specifically mentioned it was capable of heating one room while cooling another so I can assume it would also choose the best heat source for water.

  375. Swapping is sending memory to disk when not in use, paging is virtual memory that doesn't map to physical memory. Old Windows in Standard or Real mode had swap but not paging, applications needed to manually lock memory in order to ensure it is in RAM and won't move during use. With paging each process has its own view of memory and doesn't need to worry about corrupting other applications.

  376. Going through the 12v converter is fairly lossy. For a more ideal use you can get inverters which connect to the car's HV system. From user reports I've read using a Prius as a generator this way is about as efficient as a small inverter generator. And another plus compared to going through the 12v is you have much more power available.

Fortunately both of these points could be addressed without much work.

    2
  381.  @johnandmegh  The chance of the download completing but being corrupted naturally crazy low. AFAIK TLS has strong transfer layer integrity checking. You're probably more likely to run into silent data corruption (either on your PC or on the server) than getting corrupted during transit.

  382.  @oohshiny8713  The safety door interlock is done with simple switches, not microcontrollers. The primary interlock switch removes power when the door is unlatched and the interlock monitor switch puts a dead short across the transformer power when the door actually opens. If the primary switch fails the monitor switch will blow the fuse, ensuring safety. The microcontroller will have its own door switch to stop the timer when the door is opened, but this is independent of the safety interlock.

Either that or I found out by trying random keys and seeing what would happen. But then how would I have learned about Print Screen in the first place? I'm certain nobody taught me.

  389. Fun fact: Mitsubuishi is smart. Assuming your ecobee is optimally set up the mini-split will operate with full modulation, not just 2 speed. When the thermostat switches from stage 2 back to stage 1 the current room temperature is nearly exactly the setpoint. The mini-split measures the room temperature with its built-in sensors and as long as the ecobee sends out a stage 1 call the Mitsubuishi will modulate to closely maintain this temperature. Actually that was somewhat wrong but it does still rely on room temperature sensors. The proper information is in Mitsubishi Application Note 3062. When running in first-stage mode it targets a specific rate of temperature change. When the thermostat turns off the mini-split keeps maintaining the current temperature for two hours.

  391. It might not normally fix things but that's only because the files are usually fine. It's usually only helpful when there's a flaky drive or other signs of actual filesystem corruption. Windows usually performs digital signature checks when loading executables and I believe it will automatically replace system files if a mismatch is detected and the system is otherwise normally. I guess that last sentence answers the OP's question.

  392.  @danielfay8963  Those outlet testers can only detect a few of the possible wiring errors. Most notably, they cannot detect if neutral and ground are flipped or shorted. The most exciting thing is a reverse polarity bootleg ground. A tester will report such an outlet as perfectly fine, even though the ground pin is actually connected to live.

  398.  @mattmurphy7030  I think the Microsoft compiler sets the minimum required Windows version field in the PE header to something relatively recent so this particular executable probably wouldn't run on anything older than Windows 7.

  411. The important thing to note is that the different settings have no effect on efficiency. Choose a lower setting if the heater is sharing the circuit with other devices. And lower settings will lead to more consistent temperatures. Higher settings will make it heat faster (obviously) but the hidden gotcha is self-heating will cause the thermostat to switch off early so it's not actually faster at heating a room unless there is some amount of airflow. Matthias Wandel made a video about this.

  412.  @VictoriaKimball  I should probably note that the issue with inconsistent temperatures is much less with an oil-filled heater compared to hot air. The oil-filled stays warm for a while after the thermostat cycles off but a hot air heater stops putting out heat immediately.

They actually only draw 1.8a (20w) full speed but that should still be a consideration. Granted a gaming PC is unlikely to have fans like that that but a regular 120mm fan can probably use 6w. Multiply that by several fans and it starts to add up. In terms of IO all your drives will use some power and everything powered from your USB ports of course also comes from the PSU.

Older PSC motors are inefficient, especially at low speeds, but newer ECM blowers (standard for 3-5 years) remain efficient at all speeds. The new blower in my 100k furnace (78k out) only draws 350W on heating speed. A lower speed setting only draws 190W but produces enough air for a furnace outputting 65k BTU/hr. If you're building a solar backup system then definitely consider switching out a PSC blower for an ECM one. You saw my numbers, the power reduction can be substantial.

  433.  @Stepclimb  There wasn't any doubt about who you were talking about, I just like to correct misinformation. I'm not sure where I heard it originally but that's what he's called. I just looked and his website says his name is Zack Nelson; I didn't know the last name before this. People often think his name is Jerry because of the channel name. Regarding vehicle electrical systems, I'm well aware that 6S PbA batteries are usually above 12 volts. If I'm not mistaken 12v is about 50% SoC but it's best to keep them fully charged. If I find a spare battery below 12.6 volts I'll get it to the charger right away. But I still maintain that the nominal voltage is 12v. The Cambridge English Dictionary defines nominal as "in name or thought but not in fact or not as things really are". We already agree that 12v is "not as things really are" so let's focus on the first part. Every 6S PbA battery I've ever come across is labelled as 12V, accessory sockets are usually labelled 12V, and most equipment is labelled 12V unless a specific range is given. When (most) people speak they say 12V. If it's not 12V "in name or thought" I don't know what it is. AFAIK the only place people usually say 14V or 28V is on aircraft.

  434. In my opinion (having never played a Laserdisc) the inability to watch an entire movie without changing (and/or flipping) discs would be a huge downside. If LD came out earlier it might have done better but the fact that movies were already shipping on prerecorded VHS cemented its legacy. And then there was also RCA's CED which combined VHS's poor quality with LD's limited runtime.

  436. I have Windows 7 on a few machines that get connected to the Internet and I have a good reason: I'm lazy. I've migrated away on my primary machines (admittedly later than I should have) but for the system by the basement workbench that I use a few times a year to look up schematics or whatever it's not worth the effort to migrate. I don't deal with anything sensitive on these systems so I don't care too much that it's not the safest. I actually use Win98 online occasionally on my "retro" machine to read strategy guides and such when playing old games.

  439. 5G in particular runs low-power base stations. On top of that the inverse square law means the amount of energy you could pick up is negligible. It would work if you had a much stronger source of electromagnetic radiation being focused right at you. The only practical source of such radiation is the sun and then I've described a solar panel.

  443. A somewhat similar situation is leaking alkaline batteries. Some of the major brands have guarantees that they will repair or replace devices damaged by their batteries leaking. I looked at their websites and it appears they do not have a limitation on the value covered. I wonder how they would react to if their batteries damaged the controllers of a $10k pinball machine.

  444.  @BertGrink  That's easy. The registry is made up of a few hives and each is its own file. Most of the hives are in the system32\config directory, and I believe these files (COMPONENTS, SAM, SECURITY, HARDWARE, SYSTEM) are directly loaded as their corresponding entries in HKEY_LOCAL_MACHINE. The user-specific registry entries are stored in the NTUSER.DAT file in each user's profile directory.

  453. ​ @MaxDad7  I think you're missing my point. I agree the new PC will use half the electricity if it's only doing the same task but that's not what happens. You also need to consider PC idle time. There's a reason I said 4th gen instead of 3rd gen in my earlier statement and that's because that gen brought in super low idle consumption as well as the first common mini PCs. I watched a video recently where somebody's 4th gen m93p was measured drawing about 10 watts from the wall. There's not much to gain after that. And if you want to do some math, let's say electricity is 25 cents/kWh and the new PC costs $400. You'd need to save 1600kWh to make it worthwhile. If each new PC saves 30 watts (believable for going from unoptimized 2nd gen to new current gen) that's a payback period of 53 thousand hours or six years. That's six years assuming they're never shut down. Electricity cost doesn't make it worthwhile. And consider these gens are more than fast enough for basic office tasks. If most work is done over RDP there will be negligible difference to user productivity. For local business computing tasks they might be reaching the point where they're going to start to feel slow soon. The biggest reason to get them replaced is fear of them breaking. If I was suddenly in charge of a mid-large business's IT I would probably go with a six or eight year staggered replacement schedule so a good number of units are still under warranty at any time.

  472. If you're concerned about resale value you shouldn't be. Practically nobody checks heating capacity when buying a house. Even if the system were actually undersized they won't know as long as it's warm during the tour. But a 74F design temperature is fine; I believe the actual standard is 70. And there's still the heat strips available which nearly double the total available heating capacity. Maybe it would be worth going from a 2 ton to a 2.5 ton.

  473.  @jmr5125  In that case the inspectors are part of the problem. And ideally the sell sheet for the house should include an estimate of HVAC running costs because it can be such a large expense.

  474. Using a mechanical contact is a poor idea because of contact bounce and similar. The points in a distributor are made to open at a controlled time but the closure is going to be much more messy. The best solution is a hall effect sensor with a specialized encoder wheel with many pulses per revolution as well as a locating signal. This is what modern automotive engines use for fuel and ignition timing. This way the microcontroller knows the (near) exact angle at any time and can dynamically adjust everything with a high degree of accuracy.

But since (most of) our plugs are non-reversible there's no way live and neutral should ever get mixed. Usually ground is on the bottom (and right angle plugs are usually designed with this in mind) but sometimes ground is up. Sideways receptacles are very rare except near Chicago.

  482. The "average Joe" would still need fast charging, such as if they go on a trip or have something unexpected come up. But really the solution for somebody like you with different needs is to get a different vehicle. And the easy way for an employer to deal with the charging issues is make it pay to charge. If they don't want to manage that they can get a third party to install and manage everything and the employer would probably get a bit of the profit.

  500. Wood expands perpendicular to the grain. Engineered wood products like plywood and CLT cross layers so the strength axis of one stops the next layer from expanding. This also eliminates most cracking and I don't think bugs like eating the glue that holds it together, especially if each layer has been treated. I'm not an expert by any means, but I do wonder how this susceptibility compares to steel's ability to rust.

  505. That will depend the most on how often you drive. An easier metric is how much it costs per mile/kilometer if you charge at home. An "average" figure for EVs is 200Wh per km or 320 Wh per mile. If a kWh of electricity costs ten cents then each mile would be 3.2 cents. Or if you drive 12,000 miles a year you'd be paying a bit more than a dollar per day at these rates.

  507. The problem is a power meter cannot show you the amount of power which would be drawn in the future. An appliance which has different modes could draw more power in the future if it switches modes. An example is a refrigerator which draws much more power when defrosting than when cooling. The power meter will also not be able to warn you about faults which may develop in the future.
    2
  508.  @ronk9830  That's all very true, however I would suggest using the nameplate rating whenever possible when sizing cords as that should be the maximum possible steady state draw. I'll use the example of the freezer in my basement, which I actually have put on a power meter. The power meter registered a maximum draw of over 18 amps, which would suggest that a 12AWG cord is needed. However that's a momentary draw of a fraction of a second when it switches on. Because it's so quick there's not enough time for wires to heat up so it can be disregarded when selecting a cord for safety. With my measurements it dropped below 3 amps after a few seconds. This was in the winter, though. It might be more in the summer. The nameplate says about five amps so that's what I'm using in calculations. Nowadays we have both it and another refrigerator on the same 16awg cord. It might look like it's overloaded but the nameplate ratings only add to 12 amps which is less than the 13 amp rating of the cord, so I know it's safe.
    2
  509.  @ronk9830  My point is the nameplate rating already accounts for those different situations. I would only measure 6 or 7 amps max but the nameplates say I should account for 11.5 amps. Technically I should be using a heavier cord because a 16awg cord's rating of 13 amps should be dropped to 10.4 amps if used for continuous loads. However there are two or three main reasons I'm ok with this. First, the cord is out in the open. Half of it is hanging in the air where it will get plenty of convective cooling, and the other half is over the metal freezer body which will also conduct heat away. This cooling slightly increases the ampacity of the cable. Plus in this setup the cord is away from flammable materials. Even if the cord were to melt it would short out the supply and trip the breaker, preventing further damage. The final reason is that from reading the service information for the refrigerator I know it will not draw its rated load continuously. The compressor's rating is less than the defrost heater. The defrost heater won't run continuously because it is on both a timer and a thermal cutout.

  512.  @TheLoneWolfling  R410A is a mixed refrigerant and 50% of the mix is R32. The equipment that was using 410A 20 years ago is already using R32. Full R32 behaves about 10% differently so it's not a big change. It's not like R22->R410a which was a much more significant change.

  513.  @LordNementon  I'm not sure of the particulars but you definitely CAN set equivalents to policies in Windows. For instance, you can lock executables so only certain groups can use them and more complicated programs like Firefox have their own policies support. This could be rolled out by having a custom repository in your package manager (and not giving employees root access).
    2
  514.  @MistrZIGZAG  You're making numbers up. The mechanical power the blower needs is proportional to the cube of the airflow. An otherwise identical furnace with half the heat output will only need 1/2 the airflow and thus will draw 1/8 the power. When you multiply by the doubled runtime the half-sized furnace's blower only needs 1/4 the energy. If you want some real numbers, I installed a new blower in my furnace and took power and airflow measurements. At speed setting #4 (the minimum to safely handle the furnace's 78,000Btu/hr output) it draws 348 watts and pushes 1128 CFM. On speed setting #2 it only draws 182 watts but still pushes 963 CFM.
    2
  515.  @MrGadgetgav  But that actually does work. Lugging around less fuel means you get more mpgs. And a battery is usually slightly less efficient at charging when going to 100%.
    2
  516.  @jawkeye  A variable speed system can be either great or terrible at dehumidification, or something in between. It's all about the ratio of cooling power vs airflow. A colder coil removes more moisture but results in a lower COP. Usually there are different modes for cooling only and cooling+dehumidification. Some fancier systems have humidity sensors to automatically manage efficiency vs dehumidification.

  522.  @scottyhaines4226  Servers care a lot about drive speed, especially random access speed where SSDs totally win. In the old days you'd often need an array of lots of drives not for the capacity but for the random IOPS. With SSDs you don't need as many drives and the drives use much less power. Power usage / heat generation is an important consideration in the datacenter because they not only need to power the equipment but also need to pay for cooling and air conditioning. AFAIK in the server world spinning disks are pretty much dead for general purpose use (vs bulk storage). SSDs let you handle more clients in fewer servers, offering great cost savings.

  529.  @lpprogrammingllc  The bus being D0-D7 and A0-A15. It's easy enough to make something which keeps the same bus timing and you can't be sure it isn't malicious execution unless you watch it continually. You'd need to dissect it, and then keep in mind modern 6502s are built on more modern processes. The best course of action would be to use one CPU, then dissect it and if anything funny is found discard all its computational results.

  532. Sounds like it might be the Telechron Occlusion Clock.
    2
  533. As you say the outdoor unit is targeting a specific coil temperature. But since there are (usually) only two blower speeds available this results in only two levels of capacity. They also use timing information to adjust the coil temperature setpoint. If the heating calls only last a few minutes it will tune down the coil temp, if the calls have been running a long time the coil temp can be turned up.
    2
  534.  @magellannh645  I was saying that if the target was a fixed coil temperature the two fan speeds would result in two heating capacities. All the efficiency magic is how they vary the coil setpoint.
    2
  535.  @magellannh645  It's not that much of an achievement to get consistent heat output, just feed the pressure/temperature sensor into the variable frequency drive control input. And yes, the fact that single-speed systems have much lower capacity the more you need is very annoying. Surprisingly it hurts actual COP very little, it just makes the system impossible to correctly size.
    2
  536.  @magellannh645  I was going off of published data tables which assume steady-state operation without short cycling. Short cycling would indeed hurt performance. And in terms of compressors, AFAIK a variable speed one is identical to a 3 phase single speed version. The inverter is what makes it variable speed.

  538.  @chris101ward  It's definitely not a swamp cooler, that's requires evaporation in the room which is impossible with a sealed A coil.
    2
  539. Regarding point 2, I believe it isn't properly unmounted even though it's fully consistent. The FS driver in Windows probably has some state stored in "RAM" and if the actual state is changed under it bad things could happen. Having said that it is very annoying.

  544. IIRC the "IBM" 802.11 card available in the ThinkPad T30 used the hostap driver and with a firmware update it works with WPA2.

I can think of reduced parts availability due to smaller sales volumes, mechanics being unfamiliar around EVs, and also one well-known manufacturer being a d**k about repair. Since EVs are so much simpler I would expect them to be easier to repair than ICE vehicles in an apples-to-apples comparison.

  556.  @barongerhardt  Gas isn't 30 times cheaper and nobody said it was. 29.3 is the conversion factor between the archaic unit "therms" used on gas bills and the more sensible kWh used on electric bills. In my part of Massachusetts we have expensive electricity ($.32/kWh) and much cheaper gas ($1.92/therm). Adjusting the units gas is $.065/kWh or about 1/4 the cost. With these rates a standard heat pump doesn't make economic sense. In other regions where electricity is only 2x as expensive heat pumps are cheaper to run as long as your average temperature is above ~10F. For these people a heat pump will cost the same in winter but will be much cheaper during spring. I totally agree the units in this video are way too expensive. A mini-split of the same capacity is well under $1000.

  559.  @jonathanbuzzard1376  Old-school Macs let you use / in filenames long before users would've been concerned with SMB support. When switching to the Unix-based OSX they needed compatibility systems. When you enter a / in the GUI it is converted to a : for the Unix filename (and vice versa). I presume they used : as a path separator in old MacOS. I had no idea this was a thing but I was helping somebody with a file not opening. Apparently Word for Mac does not do all the necessary translations and simply can't open those files.

  560.  @COSolar6419  It depends on what you mean by "works well." Current cold weather heat pumps maintain decent capacity well below freezing but the COP still falls with lower temperatures. Below a certain temperature it's more cost-efficient to heat by burning fossil fuels.

  565.  @soulstenance  I should add that it has the electrical USB D+/D- lines but you're not going to find a regular rectangular USB connector inside the laptop. It will use a proprietary connector and power is usually a minimally-protected 3.3v instead of the standard well-protected 5v.

  567. And that's exactly why the manuals are important. If there are genuine safety concerns they should be known so people don't attempt to do things in a dangerous manner.
    2
  568.  @MrAranton  All the service manuals I've seen which have schematics also have parts listings. Somebody who is not familiar with ratings of parts can just get the exact part mentioned or one their parts supplier lists as a substitute. And if somebody is reading the instructions and the instructions say to do something they don't know how to do they'll either research it separately or take it to somebody else. If you're talking about hazards like charged capacitors consider this: every video about electronics repair mentions that. I can't imagine anybody solely using manufacturer supplied information unless they already have background knowledge. Consider this: in the old days (certainly the 1950s and 60s) you could easily get anything needed in order to repair your TV. Yet somehow TV repair shops still existed. That's because people who didn't know how to work on TVs would take it to somebody who did, either a professional or just somebody they knew.
    2
  569.  @MrAranton  There are some risks of people misunderstanding service info but I think the risk of improper service due to lack of service info is more serious. Would you agree that pros should get service info? I don't know how you'd limit access to professionals without gatekeeping what a professional is, which would clearly be problematic. Why not ban service info entirely to make sure nothing gets into the wrong hands? Another thing, large appliances and some smaller ones including microwave ovens usually come with service info which is in a packet and/or sticker on the back of or inside of the unit. I don't recall anyone getting sued over this. It also isn't true that custom ICs didn't exist in the 1950s. They weren't modern ICs but rather a collection of separately manufactured passive components encapsulated into one part. A well-known example is the "resistor-condenser networks" well known on Philco Predictas. The difference is the internal circuit was always published on the schematic and third parties were able to make their own clones. For modern parts which can't be replicated by hand it's obviously not so easy. Other R2R initiatives like the one up in California cover parts availability. But even without official availability, parts can be taken from other dead units, such as the case with an automotive junkyard.

  570. Now that everybody's asked why you used uuencode instead of base64, why don't you put this into a data: URI? Then any QR reader which will launch links from QR codes will automatically get the binary. There's rumors the Windows Camera app might be getting QR support. If that's the case data: URIs will let you load the program without using zbar or another third-party reader.

  571. A large-ish capacity L2 charger at California-emergency electricity rates is less than federal minimum wage. If you have more common electricity rates giving away free charging would be the equivalent of a $2/hr raise. Less if they do a lower-capacity charger.

  572.  @andykillsu  A big fat no to what? Briggs introduced their "Magnetron" electronic ignition back in 1982. You might be confusing electronic ignition with computer-controlled ignition.
    2
  573.  @andykillsu  A distributor distributes spark from one ignition coil to multiple cylinders. The very idea of distributors doesn't make sense on a single-cylinder engine. On old cars the points were usually colocated in the distributor and I assume this is what you are talking about. The points were physically interrupting current to the external ignition coil to time the spark. In slightly newer cars (such as those with Ford's Duraspark) the physical switch was replaced with a magnetic sensor. Even though the spark is still timed by the physical location components this is electronic ignition.
    2
  574.  @andykillsu  Also the Briggs & Stratton website disagrees with you. They have a page titled "How to test and repair small engine ignition system problems". I suggest reading this if you remain confused. I'll quote one sentence here. "Because the ignition module is electronic and does not utilize moving components, it is normally one of the most reliable part of the engine."

  592. To be more accurate the code requirement (as of the 2017 NEC) is to have fixed lights in every room. An exception is provided if you have a switched outlet but this exception is only valid in certain room types. So the bathroom and kitchen need ceiling (or wall) lights but it's up to the designer if your bedroom and living room have switched outlets or overhead lights.

  603. Yes that's right. The absolute minimum allowed for new single-family homes is 100A and this gives us 24 kilowatts. In recent decades 200A is more common. And yes there are limits. My service may be good for 48 kilowatts but I don't think the distribution transformer it's connected to is rated for more than 50.

  605.  @i6power30  It doesn't cost much for the manufacturer to add V2L to a new EV. If the charger is using synchronous rectification the existing power electronics can be run in reverse by changing the much cheaper control circuitry. Or the inverter for the traction motor can be used for V2L if the vehicle is stationary. I know some EVs already use the drivetrain power electronics when charging.

  606. Your 230v 63a 3ph is almost 44 kilowatts. American 200a service (200a on each 120v leg) is 48 kilowatts so it's pretty comparable. I've watched videos of English electricians and 63 amps single phase seems to be their norm with 100a as an option. Worst is Italy where if I'm not mistaken 16a single phase is the norm with 25a as an upgrade option.

  610.  @whitslack  If the wiring was done in conduit it will be well-grounded and if done with armored cable it will probably be good enough even if not intended for grounding. It's really only ancient knob-and-tube and early non-metallic cable which won't have a ground. This leaves a decade or two in the thirties or forties where a grounded box would be fairly common at home. Of course commercial buildings are much more likely to be conduit. I work in an old building and most of the wiring is in surface mounted conduit, likely from the original electrification. It pained me to see a grounding adapter used without the screw.
    2
  611.  @whitslack  NM-B is only installed in conduit under very specific situations (to offer physical protection of a short section of the cable), usually conduit is filled with loose wires such as type THHN). The second situation I was referring to is armored cable which back then would be hot and neutral inside a steel or aluminum sheath. Since the sheath is metal and is attached to metal boxes using metal clamps it happens to provide ground continuity. Please not that the sheath is not rated for grounding duty but it's still better than nothing. While I did not say ungrounded receptacles were ever installed when a proper ground wire is present, that did sometimes happen. As to why, I'd guess ungrounded outlets were cheaper. It's similar to how you can install 15 amp receptacles on 20 amp circuits.

  612.  @sepez  In America we (apparently) use kcmil (thousands of circular mils, also called MCM) for wires larger than 0000 AWG. 1 kcmil is 1000 times the area of a circle with a diameter of one thousandth of an inch. Other parts of the world use square millimeters which just makes calculations so much easier. For example a 2.5mm2 wire can carry 2.5 times as much current as a 1.5mm2 wire. No need to look at a table to figure that out.

Tamper resistant outlets aren't required everywhere, only in homes and certain places which are likely to have children. Even then you don't need tamper resistant outlets if they are more than 5 and a half feet off the floor. If you're installing an outlet high up (such as for a garage door opener) or at a business you don't need the shutters.

  625.  @heatshield  There are US outlets with switches. Some examples are the Leviton T5225 and T5625 although these appear to only have 15a switches so would not be suitable for 20a kitchen circuits. You'd also need to keep in mind code rules for outlet quantity and spacing as well as GFCI.

  626. FMVSS in the US require that you can't drive when charging. Even if not required many cars retask some of the motor electronics for driving, making it physically impossible to charge when driving. Although having said this, it would occasionally be useful to charge when driving. It would let you use an ordinary gas generator as a range extender if needed.

  629. Without a compositor anytime part of one window is uncovered it needs to immediately redraw itself. With non-optimized applications this means the entire window gets redrawn which can be computationally intensive. You've probably seen Windows XP screenshots where an error dialog is dragged over a window and leaves a trail, this is what happens when the background window can't redraw in a timely manner. With a compositor the WM knows exactly what each window looks like so moving and/or switching between windows is always instant. And related to that, compositing window managers can show miniature previews when using window-switching functions like Alt-Tab. It's much quicker to tab to a moving picture of Brodie than it is to tab to the text "Begone Wayland". On my crappy old netbook compositing had a noticeable performance hit. But when you only have a 1024x576 display the ability to switch windows instantly made it worth it.

  636. The answer is there needs to be a difference in price between home consumption and home generation of electricity. One approach is obvious: having one price/kWh for buying and one for selling. The possibly more economically sustainable approach is time-of-use rates which reflect actual wholesale prices. Once everybody has excess solar production the price will be $0 during the day but $$$ at night. This will naturally incentivize energy storage systems.

  641.  @Lapatt_Blue  From an emissions standpoint centralized burning of fossil fuel is still better than burning in individual vehicles because it's easier to manage. And solar panels can provide enough energy if I'm not mistaken. A local solar installer put panels on its lot and was able to power its electric cars and still have plenty of energy left to give to other nearby businesses. For something less anecdotal, read on. Americans drive a total of around 3.2 trillion miles a year. The "average" EV consumes 201 Wh/km. This would mean America would need about a quadrillion Wh per year to power cars if everyone went electric. That's a lot. Where I live in Massachusetts (which being in the North gets less sun than average) we get over 4 sun hours per day, or about 1500 sun hours per year. An average solar panel is rated 300 watts, so at this insolation would produce 450 kWh/year. This would mean we need about 2.2 billion solar panels. There are about 140 million American homes so that's 16 panels per home, which isn't too excessive. If you place panels on businesses, highway exits, etc it's certainly doable. And nuclear is still an option. Even including Chernobyl it has a better safety track record than coal plants and we're not going to build another RBMK like Chernobyl. Even existing American plants which are based on antiquated designs are an order of magnitude safer than that, and next-generation designs are much better still. You're left with nuclear waste, but is that really bad? Everything in it was already in the crust, it's only hazardous because it's concentrated.

  642.  @Lapatt_Blue  If everybody has electric cars they already have massive battery banks at home. The manufacturing is the main problem with the sustainability. Using clean electricity to bootstrap the production processes of other clean energy components would help, but the question is is that enough? Most of an electric car is easily recyclable, but how good will battery recycling become? I see EVs and clean electricity generation as two separate but related problems. They can be addressed separately from each other.

  657.  @lal12  Basically yes. Except in the DOS days there wasn't a real MMU* so anything could install its own custom handlers. Keeping the CADel combination reserved was really just a convention. MS later took advantage of that because it was the only key combination virtually guaranteed to be unused by application software. *386s (and technically also 286s) have MMUs except for compatibility purposes these were disabled under plain DOS.

But the second part is probably not the case.

  668. Today real-mode addressing is just a pain but keep in mind that the 8086 was released in 1978. Back then most microcomputers only had a 16-bit address space and programs used less than that. I think real mode was a nice way to provide extra memory on a 16-bit platform without being overly complicated. Early protected mode only added two benefits. the first was memory protection but Win16 didn't really take advantage of that. The second is the ability to customize base addresses for segments. Unless you have lots of dynamic memory allocation and freeing there isn't much gain there.

  676. The largest laptop batteries are just under 100 watt-hours, or 0.625% of Alec's calculated energy storage. Assuming power consumption is the same from the wall or from battery you'd never save energy by doing this. You could theoretically save money but even at a very high 50 cent/kWh rate a full charge costs less than four cents. In my opinion the wear on the battery would not be worth it.

This is more than enough to make websites seem slow. Best case you have 2 RTTs to establish a TCP connection, more to setup SSL/TLS, and only then can you start downloading. And then loading things like images and stylesheets will be more of the same delays. And TCP with high latency takes a while to reach full speed and packet drops become more impactful.

  700.  @Leeki85  The 32-bit file size has been a part of FAT's directory entry structure since very early versions of DOS (when the largest partition size supported was 32 megabytes). When Microsoft designed FAT32 15 years later they kept the same entry format so most of the DOS code could be reused. The DOS kernel under Win9x still ran entirely in real mode so those memory constraints were still an issue. Btw having the maximum file size less than the volume size is quite common. NTFS volumes can be up to 2^64 clusters large, while the max file size is only 2^64 bytes. Ext4 with 4k blocks goes to 2^60 byte partitions while files are only 2^44 bytes max (16 terabytes, already smaller than the largest hard drives). ZFS supports 2^128 byte filesystems but only 2^64 byte files. Some common filesystems such as HFS+, btrfs, and XFS do have the same size limit for files as the entire partition but this attribute is far from universal.

  715.  @bobprivate8575  The Dell fan I'm talking about from a Dimension E521 was actually made by NMB in China. I have another one, probably from an Optiplex, which may be a Delta but I can't find it at the moment. Fortunately I know I won't accidentally plug it into a 1A mobo header because it has a different connector. I also happen to have an HP server with 60mm Delta fans (Chinese according to pictures I can find online) rated 3.3 amps. When they are spinning full speed the system is indeed very loud (even at 35% it gets irritating after a few minutes) but I measured and they only use 1.8 amps. This server also originally shipped with twelve 15000 rpm 3.5" drives which would've used around 180 watts in use. But yeah, neither of these are going to be found in an ordinary PC. Also, 100 linear feet/minute isn't that much. A 120mm fan is about .12 square feet so 100 ft/min would be 12 CFM. For comparison, a Noctua NF-A12 is a max of around 60CFM.
    1
  716.  @bobprivate8575  I'm sure about those numbers. The datasheet for the Hitachi 15k600 says 16.6w typical operating power and for the 600gb capacity. Drag forces are proportional to the square of the velocity so I'd expect 2.25 times the spindle motor power when going from 10k to 15k rpm. With fan measurements the smaller the fan area the more velocity if the CFM stays the same. I think airspeed of a fan doesn't matter unless you need to cross the bridge of death. For most purposes CFM (or m3/hr for metric folks) is probably the more useful metric. 100 CFM sounds plausible for a high power 92mm fan. On second thought my 60mm ones might be rated around 150 CFM, so 100CFM seems low. Either way, it's completely irrelevant for sizing the PSU on a gaming PC.

  728. Multi-stage in an HVAC context means the unit can operate at multiple power levels, it's still only one refrigeration loop. This is totally different than a cascaded system with multiple series loops. I don't think you are grasping what a cascaded system does. I thought the Mitsubishi units only got a claimed COP of ~1.5 at the bottom of its temperature range. If the Flooid is claiming a COP of 2.2 in the same conditions it's definitely more efficient. Cascaded tech can give you a heat pump that works when it's much colder outside.
    1
  729.  @deathound  It really sounds like you don't know how cascaded systems work. They have two compressors and two refrigerant loops but only one outside air coil, only one inside air coil, and no redundancy. A crude cascade system is a refrigerator in an air-conditioned house.
    1
  730.  @deathound  Non-cascade "multi-stage" systems are like putting multiple window AC units in the same large room. Each refrigeration loop has one part inside and one part outside. Each loop sees the same working temperatures, let's say 100F outside and 70F inside. A cascade system is like putting a refrigerator inside a room cooled by a window AC. There's only one outdoor coil and there's only one coil inside the fridge. The first loop (the window AC) cools from 100F to 70F and the second loop (the fridge) cools from 70F to 37F. A proper cascade system goes one step further by directly thermal coupling the two loops. Instead of the window AC with a refrigerant->air heat evaporator and the fridge's air->refrigerant condenser there's just a single refrigerant->refrigerant heat exchanger that acts as both one system's evaporator and the other's condenser. TLDR: non-cascade multistage = outdoor air->refrigerant->indoor air + outdoor air->refrigerant->indoor air. Cascade system = outdoor air->refrigerant->another refrigerant->indoor air.
    1
  731.  @deathound  Yes, the main usage is to reach temperature extremes. You need huge pressure differentials when going from very hot to very cold using a common refrigerant and this isn't practical. Even if you can attain the pressures needed it's not very efficient. At some point the higher efficiency of a different low-temperature refrigerant overcomes the inefficiency of needing a second stage to bring it up to room temperature. The "magic sauce" is intelligently varying the power of each stage and applying bypasses in order to always achieve the best performance. In other words, yes it's excessive when a single-loop system can do the job well. Above 5F/-15C a regular system works well. Below -20F/-30C you need something else.
    1
  732.  @deathound  For the central US you're going to need a heatpump because winter still exists, but not enough to need a special heatpump. For Northern New England where (I think) there's a decent amount of time below 0F it might make sense to have a cascade system assuming it really does perform better.
    1
  733.  @deathound  I'm also in MA and there was that one day a few years ago when it -20F. It's rare enough that it's rational to use emergency electric heat but on the other hand it just feels wrong to get a heat pump that doesn't work at all that low. I'd really need to know the actual performance at different temperatures. How cold does it need to be in order to perform better than a standard model? Here the 50% heating temp (a term I just made up) is about 30F so this cascade system surely isn't worth it. It would probably only offer better performance something like 2% of the time. If if offered better performance for 25% of the yearly heating needs it would be worth considering. Note that I'm saying percentage of heating needs, not percentage of time.

  735.  @Pyro-Moloch  The problem with minimizing on the taskbar is it only does one window at a time. If each task has multiple windows it can get old quickly, especially when you have multiple instances of the same application. On smaller screens I might use adjacent workspaces for reference materials and the active working file. Alt+tab works fine for quickly swapping between the two but when a third window (such as a calculator or terminal emulator) is added a quick Alt+tab starts jumping to the wrong window. Switching workspaces is one click yet can restore dozens of windows at once.
    1
  736.  @Pyro-Moloch  The smaller the monitor, the more you need to switch views. With only one virtual desktop you have all your windows on one taskbar and it's annoying to pick out the specific window you want. All browser windows look the same, all PDFs look the same, all file managers look the same, etc. It doesn't take much time to find the right one but it interrupts stream of consciousness. It's much easier if you can press one button without thinking and be shown the window you want to see. Virtual desktops makes that easy. Even if you still use taskbar switching it eliminates extra taskbar icons to keep it clean. Then there's also the idea of having one workspace per task. You can have one for one work project, one for checking on personal communications, and one for work email.

  743. Except it's not more efficient if your pipes are well-insulated. More importantly, you can use more efficient heating methods (specifically heat pump) with a tank but simply can't with an on-demand system.
    1
  744.  @ThatTieDyeGuy  Modern water heater tanks are very well insulated so in terms of running costs the tank size has negligible impact. I suspect most energy losses come from the hot pipes. If you want to design the house to be efficient then put the shower and kitchen/laundry next to each other and place the hot water tank in the same area. Then you eliminate most of the hot water pipes, the associated heat loss, as well as the water lost waiting for hot water to arrive. I'm sure we can agree on this. If you're heating using electricity then you obviously want the tank to be heated via heat pump to save energy. I would think it's more efficient to do all the heating in the tank but if running the tank colder increases longevity then that might be a reason to do a bit of the heating via a point heater. But you also need to keep in mind that 90F, your suggested tank temperature, is ideal for Legionella growth. That's no good, to ensure safety it needs to be 124F. At that point there's no use in having a point heater nearby. If there are other locations requiring hot water, such as a bathroom which lacks a shower, then it could make sense to use a point heater from cold water rather than running long hot water pipes.

What I might've done instead is hold a certain day in while you plug it in, then press a specific other day within a few seconds. If anything else is pressed in the meantime, cancel the reset procedure. This way is both quicker to reset and is less susceptible to accidental resets. You might be touching Jan 1 when you are hanging this up, or something might hang over and hit the button. The other option is just omitting the reset function and just resetting each day individually.

  752.  @SeattlePioneer  Every benefits from grid-tie. Grid-tie is just the ability to sell power which is separate from getting paid for it. In most areas you do not get paid full retail price for excess solar. In other words you do not get to use the services of the utility company without paying for them. Net metering does exist in some places but it's not the norm. And where it does exist large producers are not eligible.

  753. While the CRT itself is the shock hazard most modern flyback "transformers" include a multiplier circuit which could hold a bit of charge as well. But the big hazard isn't the shock itself, it's the resulting involuntary movements which can put you in contact with something more dangerous.

  757. With my power company there are two charger per kWh: generation and distribution. We should definitely be paid the generation cost if we are generating extra electricity for the grid, otherwise why would we want to? Getting paid the full retail price including distribution charge (as is done with true net metering) isn't fair because we aren't the ones distributing the power we make.

  758.  @williamcahill2462  I've never heard of an American stove keeping the gas off when the flame isn't proven. Newer ones have a spark ignitor activated only when the knob is in a specific position. But there's no interlock, if it fails to light or the flame goes out for any reason the gas will stay on. Ovens are different and work as you describe. Most new gas ovens are electronically controlled with a hot surface ignitor, but I have one which lights an intermittent pilot when turned on and then works like a traditional mechanical control without electricity.
    1
  759.  @libertyman3729  I think you mean you can't buy a stove that's designed to need a match to light. If the burner is dirty or something is a bit out of place (or if the power goes out) you still need a match or other external ignition source.

  760.  @pete_lind  I remember the Merrimack Valley incident and it didn't happen like that. A mistake in pipeline upgrades led to the distribution gas pressure being 150 times greater than the proper value. That's not the fault of any stove. If your 120/240v electrical service was fed with 36,000 volts you'd have electrical fires from the wires themselves breaking down, not to mention from equipment. Your circuit breakers wouldn't help much either.

  766. It sounds like you have hydronic underfloor heating with a boiler. This is the best scenario for heat pumps. You need an air to water heat pump (AWHP). One brand which I believe is friendly to DIYers is Chiltrix. They have diagrams on their website of how the entire system would be plumbed and how it would work. It's a "monobloc" unit which means it's fully self-contained and no refrigerant piping is needed. Just run power and two pipes outside.

  767. TLDR: I'm not sure if a correctly-behaved single core utilization column is feasible to implement. Long version: That would be a great addition but I don't think what we want is practical from a technical standpoint. Let's say there's a two-threaded application. Thread A processes some data, then waits while thread B processes it more. Thread B does the same, waiting for new data from A then processing it. This would be a full single-cored load (because only one thread actually runs at a time) but each thread only uses half of a core. What number should Task Manager display for single-core utilization? Based on the description of the application's workload it should 100%. Now let's consider a multimedia application with two threads, each decoding its own independent video stream. Each thread needs 50% of a core to display in real time. Therefore Task Manager should display the single-core utilization as 50%. These two different applications have the exact same metrics for thread CPU usage, yet they have different logical single-core usages. If the display algorithm produces the correct readout for one it will produce an incorrect readout for the other. For comparison, the 'top' command in Linux distributions displays process CPU usage relative to a single core. Both of my example applications would show 100% usage. Btw multicore systems were around when Dave was working at Microsoft. Multi-socket servers and workstations were supported by NT and by Server 2003 the Pentium 4 HT had reached the consumer space.

  780. I think hydronic distribution is better than VRF. Instead of running tons of refrigerant lines you only need ordinary water pipes. The pipes can lead to a separate heat pump with heat recovery. Compared to VRF you can upgrade the heat pump without replacing the entire system.

  784. TLDR: I used Arch 11 years ago. I don't use arch anymore. My first Linux experience was from a CD found at a yard sale with Freespire Linux which I installed on an old (Celeron 466) PC. My first "real" distro was Arch, installed around 2013. Because I didn't religiously read the news page before every update I ended up without a copy of the shell. I somehow was able to use the existing bash window and fix the system. That put me off Arch. When I got my first ThinkPad I went with Debian and I no longer needed to worry about everything breaking. After that my distro of choice was Xubuntu, now it's Mint.

  794.  @mattdaddy_888  If you cut into the bright orange wires you could get a serious shock but needing to do that isn't common. A good analogy might be high pressure lines on a diesel or gasoline direct injection engine. Hydraulic injection injuries can kill and worse yet it's easy to be unaware of such an injury when it happens. Ultimately you really shouldn't be working on any dangerous machinery if you aren't careful and take precautions.

  795.  @mattdaddy_888  Discharging the battery won't do much in terms of shock safety. If you need to work inside the battery pack then you should probably use gloves and fully-insulated tools if you want to ensure safety. I would think many mechanics would remove the pack as a whole and take it to an independent battery shop if refurbishment is necessary.

  817.  @takakazushi6703  I did a little bit of research and I don't think there are any adapters supported in OPNsense that will give you better than 802.11n. It might even be limited to 802.11g. If you want any recent standards you'd need to run a Linux VM (such as OpenWrt) with PCIe passthrough on the OPNsense box. From a software standpoint this is more complex than a separate AP. I did find a guide using the FreeBSD bhyve hypervisor but as we all know links aren't allowed in viewer comments.
    1
  818. ​ @takakazushi6703  If you flash OpenWrt onto consumer routers you can turn them into powerful APs without vendor lock-in. The main downside is the lack of central configuration but for a small single-AP home setup this isn't a problem. It's possible to run OPNSense and OpenWrt on the same hardware using virtualization and PCIe passthrough. This results in reduced hardware complexity but increased software complexity comapred to having separate devices. The billions of all-in-one home routers aren't "wrong," they're just not optimal. They are made to be easy to install, not to offer the best performance or features.

  833.  @lanzer22  Hydrogen cars have their own problems which IMO means they will never reach mass market appeal. Have you seen Jason from Engineering Explained's video on the subject? Some highlights: low energy density and the need for advanced containment vessels. Hydrogen combustion engines have the low inefficiency of any other ICE combined with hydrogen-specific issues. Hydrogen fuel cells are more efficient but require rare precious metals and IIRC have a limited lifespan. And then there's the production aspect: commercial hydrogen is usually produced from fossil fuels using steam reforming and green hydrogen comes from electrolysis which is low efficiency.
    1
  834.  @argh100100  A 98% efficient system has twice the losses as a 99% efficient one but who cares? I know electricity transport isn't quite that efficient but AFAIK it's still at least 80% in almost all cases. Very long or underwater AC lines have lighter losses but there's a relatively easy solution: high voltage DC. Switching lines from HVAC to HVDC eliminates all the capacitive losses.

  835.  @argh100100  20% loss, that's the same as the 80% efficiency I suggested. Still not bad. IIRC hydrogen fuel cells have a lower efficiency and that's before you consider transportation losses, let alone generation losses.

  845.  @MonkeyJedi99  Since the codes change every few years practically nobody lives in a house that's up to modern code. I don't think the basics for wiring (not sure about plumbing or construction) have changed noticeably in the past fifty something years. If you need to work on an installation where things were done super differently chances are you'll just add a new part using modern standards and leave the old stuff alone. If you're not doing work chances are it won't make too much difference. An old house may have a few ungrounded outlets instead of relatively many grounded ones, but grounding adapters and power strips should make up the difference. If you don't mind me asking, what sort of inconveniences do you encounter from living with outdated wiring?
    1
  846.  @MonkeyJedi99  Yes, before using an average grounding adapter you need to check for actual grounding (the instructions say this but not everybody reads them). If your boxes aren't grounded you'd need to use GFCIs unless you can add grounding. I've never seen an unpolarized wall plug, and if a polarized socket is installed backwards it's the installer's fault, nothing to do with the age. Questionable GFCIs, always test monthly (or at least when you first move in). About overloading circuits, code currently calls for 3VA/sqft for regular circuits, I don't know when this requirement started but I believe it's quite old. That's why I mentioned power strips, I think more outlets are required now but not more ampacity. I don't know the history of the small appliance branch circuit rules but I'd imagine kitchens have had dedicated circuits by convention if not by code, as appliances like toasters have been around forever. Surely there's some circuit you can find for your microwave which isn't shared with all your lights. In my old house we used to run our air conditioner from a heavy extension cord plugged into a different room. Grounding to plumbing shouldn't case any shocks (especially since no current should flow on ground), that's still done today in some cases. Maybe you had some metal plumbing replaced with plastic and not bridged, or maybe an improper N-G bond has been added. Either way, that's the previous worker's fault, not from the building being old. Side note, it's a real safety issue so the landlord should fix it. Once you find a store selling the fuses you need you can stock up and it becomes a nonissue. I think they also make screw-in breakers now if you prefer. Ideally you'll figure out what each fuse feeds and avoid future overcurrents. Well yeah, you've certainly made the point that there are inconveniences which are caused by old standards and more importantly shoddy upgrades and repairs. Why did you bring this up in the first case? Weren't we talking about wire colors?

Plus to do as you describe you'd need additional high-power converters to decouple the capacitor and battery voltage and that will just add inefficiencies. On top of that batteries in EVs (especially plug-in hybrids) are designed to handle high current. Unless you have something like a first-gen Leaf which lacks a battery cooling system it's a complete non-issue.

  863. While a 120v device will use more current than an equivalent 240v device, that increased current makes no difference in terms of getting shocked. The only thing that matters is how much current flows through the person, and a lower voltage means more current will flow through a person on higher voltages assuming they touch the live wires the same way.
    1
  864.  @christopherbedford9897  Higher current only means more heating if the same thickness of wire is used. However I believe we use thicker wires so that point is cancelled. The thinnest mains cords we have here are 18AWG, equal to 0.824 mm2. And regarding chaining power strips, the advice not to do that seems to be gone from the general mind. People chain them all the time but more importantly overload them often. In something like a breakroom where there's only one outlet there might be a microwave, coffee maker, and toaster oven all plugged into the same power strip. When too much is switched on at once the splitter's built in breaker trips. Perhaps in the past unfused splitters were more common, and of course if a 15a power strip is plugged into a 10a extension cord there is the potential for overheating. Basically if we put fuses in our 120v extension cords they should be just as safe as 230v ones. And regarding the actual shock hazard, skin resistance appears to be nonlinear. This means an equivalent shock at twice the voltage is more than twice as dangerous.

  865. In a practical sense, if everybody keeps their existing heating system as a backup it shouldn't make a difference in peak grid usage. Worst case draw would remain what it is now. Note that doesn't mean it's not an issue, in some places it obviously is already an issue.

  874.  @extreme8808  US and Europe use different metrics for octane ratings. The US uses (R+M)/2 while Europe uses RON. Our standard 87 octane in the US is equivalent to 92 in Europe and our 'premium' 93 is 97 in Europe. It's really only a minor difference. E85 is around 95 octane in the US and around 103 in Europe, but this is really only 15% gasoline. And no, this isn't a case of us using 'wrong' units like feet instead of meters for no apparent reason when measuring the same physical quantity. RON and MON are different measurements in the same way that liters and kilograms are different measurements.

If they do put chargers on people's property it will probably be treated with easements the same way other utilities already are. When fiber-optics came to my area they installed a box in my yard next to the existing phone and cable connection boxes.

  881. ​ @Toastmaster_5000  With a few exceptions DC devices are much more expensive than their AC counterparts. It's just not worth it unless you're talking about a small 12v system. The bigger issue here is that the Enphase system is entirely AC coupled, leading to an extra two conversions every time you are running from battery.
    1
  882.  @Toastmaster_5000  For things like computers the only affordable DC-in supplies are low-voltage non-isolated units. At such low voltages you need thick wire or else the voltage drop will cause excessive losses. And the non-isolated nature means you'll run into ground loops if you connect multiple pieces of equipment together. Most of the inefficiencies are from the isolation step which is absolutely needed if you are running more than a couple dozen volts.

  889. Exactly what I was thinking. I'm guessing somewhere around 10-20 microfarads would be about right. But to make it last better put a resistor, maybe 100 ohms, in series with the capacitor to limit the surge current. So basically replace the jumper wire with a diode, then put a 10uF capacitor and 100 ohm resistor across the switch.

  904. Exception: hard drives. SATA drives are made to be plugged and unplugged from a running system. I've also hotplugged fans, but I still agree with the general advice of never messing with stuff when the system's powered. I might have fried some RAM once by doing that. For cable management, my number one rule is to make sure the cables stay out of the fans. It's also nice to keep other objects, such as fingers, out of fans. If you have extra power connectors you can always cover them, either with specially made covers or just with tape.

This is 256 gigabytes and Linux is the only thing that might possibly support it. Maybe that's something to try...

  912. I think a better option is a whole-house surge suppressor. Plug-in ones can dump current on the ground wire. If equipment is connected together this could cause malfunctions. Also plug-in surge suppressors don't do much for hardwired devices. But really, is there any reason an expensive appliance can't be made to handle typical transients? If adding a few MOVs would reduce their warranty replacement costs you'd think they'd do that.
    1
  913.  @gandalfgreyhame3425  If you only have one electrical panel the whole home suppressor should protect against spikes generated on a different circuit. Whenever possible I plug the vacuum cleaner into a different circuit from electronics. And while things like built-in refrigerators and small appliances have a regular plug there are other appliances like furnaces which are almost always hardwired. Also I wouldn't want to put a surge suppressor in an area that is not readily accessible. If it has proper thermal protection it should be fine but I've heard too many stories of the MOVs catching fire. And regarding an extra 10 cents to add a MOV, I would hope the manufacturers do some failure analysis. Let's say they know boards are dying from power surges and it costs them $300 to replace under warranty. If a 10 cent MOV saves 1 warranty call per 1000 units sold they'd be netting an extra $200k per million sold.

  914. ​ @gandalfgreyhame3425  AFAIK an arcing electrical connection like you had is probably the worst problem you can have. Besides the obvious fire risk it causes lots of high frequency noise which is bad for all the circuitry. Worst of all the household power service has a high impedance at high frequencies so noise can appear on undamaged circuits as well. I don't have any AFCIs but I've heard of many people hating them because of nuisance trips. I wonder how many of these nuisance trips are faulty detection and how many are actual faults which are slowly destroying all their electronics. I will disagree about one thing. I can assume my house wiring is doing what it's supposed to be doing. I just can't assume that anybody else's house wiring is doing what it's supposed to be doing. This is especially the case in an old large setup that has had a chance to be messed with. Or if you have an overhead service drop the wind, rain, and other elements could mess with it over time. On a bit of a related story, I've had the opportunity to see laptop hinge durability testing being done at Dell. Their robot was holding the laptop by the exact center of the screen lid and applying force in the optimal direction. I was saying to my self, those aren't realistic conditions. Under real-world conditions like grabbing from the side of the screen while holding down on the opposite side of the laptop base you'll certainly get much less than the rated 100k or whatever cycles. I'm guessing appliance development is similar. If all their product testing is done with a well-regulated and filtered supply their control boards will last forever. In the real world they could fail every six months.

  933. I don't think you realize how expensive DIP switches are in the context of small computers. IMO the best solution is to have a read-only chip on the motherboard which contains all the PSB keys. That way you could change CPUs and still have the security features. Many of the flash chips used for PC firmware storage already contain provisions for hardware-write protecting some of their contents. By using this there would be zero cost to the implementation. This is actually what Chromebooks do to ensure boot integrity.

  942. The reason the non-generator engines often run at 3600rpm is that this is where most gasoline engines produce maximum power. I believe it has nothing to do with 60Hz power. It could be informative to look at outdoor power equipment made in Europe (or other 50Hz regions). Their generators definitely run at 3000rpm, but what about everything else?
    1
  943.  @Nonplused  On a synchronous non-inverter generator the rpm and line frequency is directly related, I'm not arguing against that. I'm saying that it's a coincidence that small engines usually run at the same speed. It's worth noting that on generator speeds the number of pole pairs is also a factor. A 2 pole 60Hz generator indeed runs at 3600rpm but a 4 pole generator only runs at 1800rpm, a 6 pole generator 1200rpm, and so on. While portable generators are 3600rpm stationary backup generators are usually 1800rpm. I think larger industrial-scale generators usually are slower. IIRC a small-ish hydroelectric generator I saw was 900rpm. The number of phases does not change the relationship between rpm and frequency. Regarding what happens when generators are connected out of phase, I've heard stories that enough force can be generated to snap the generator's shaft. It's also worth noting that this only happens with synchronous generators. Induction generators run slightly faster than the grid and the resulting slip results in current flow. An induction generator is physically the same an an induction motor. While an induction motor might run at 3450rpm it would run at 3750rpm as a generator.

  944.  @Nonplused  Most of these small engines are actually more efficient around 2600 rpm. To get back to my previous question, what rpm do German snow blowers run at? German generators run at 3000rpm so if your argument is correct we would expect German snow blowers to also run 3000rpm. For something more interesting, most modern small engines are copies of Honda designs. Japan is unique in that they have both 50 and 60 Hz power. Their generator engines must run fine at both 3000 and 3600 rpm. If their engines can run well at either speed there must be a reason why the snow blower would use one speed over the other.

  955. Windows (at least XP and newer) actually handle screen savers in a better way, they're (mostly) just regular GUI applications.

Once the screen saver is dismissed the login UI is launched or it switches back to the original desktop with all the windows. I see no reason why a compositor which already has a screen locker also couldn't launch an external executable and display this over the login screen. After all they already have the ability to display the output of external applications.

  963. If your system is unable to reach the set point then it is undersized. A perfectly matched heating system will eventually bring the house up to design temperatures. I'm guessing you currently have a furnace system in which case Alec's comment needs to be read carefully. Choosing a heat pump output to exactly match your current system will likely be a good size and your desired extra 30% would come from aux heat.

  964. Subnetting and VLANs are often used together. Unless you have multiple subnets running on the same cable (which is generally a bad idea) you need one port on the router for each subnet and then a separate switch if there's more than one device in that subnet. Using VLAN-aware equipment you can let one cable and switch act as many, reducing the physical complexity.

  977. The oversized system will recover temperatures faster but unless it's literally the coldest night of the year a properly sized system will also increase the temp just fine. A decent smart thermostat won't lower the indoor temperature unless it knows it is able to heat back up. So you'd have slightly more heating these coldest 87 hours of the year, not 40 hours a week.

It appears to be wired in parallel with the tank rather than in series.

  986. On a furnace the main failure point is the heat exchanger which can fail from thermal cycling. So reducing the number of cycles extends lifetime. Your motors (blower and induction) will die faster if run continually but these are relatively cheap. More importantly they are easy to change. As a DIYer I can change my blower motor in under half an hour. Since the heat exchanger is the "heart" of the unit you need major disassembly, including removal (and repiping) of all the gas-related components. Unless it's under warranty it will be better to just replace the entire unit if the heat exchanger goes.

  987. If yours offers better heat output at the same outside temperatures it probably has greater electrical requirements. If you need a 240v outlet or a dedicated circuit it's not a fair comparison. Having said all that, $3000 is unreasonably expensive. $1500 is more reasonable and still double what a similar performing mini-split costs.

With incandescents of a given wattage lower voltage bulbs are much more durable than higher voltage ones. With all the vibrations in cars this means higher voltage bulbs aren't practical. The other option is of course LED but modern LEDs run around three volts, so you'd either need to run 100 LEDs in series (IMHO impractical for things like turn signals) or have some sort of voltage converter.

  1012. How much of your system they can reuse probably depends on the pressures involved as well as material compatibility. I believe older systems run at lower pressures which might not be compatible but if you have a modern central air conditioner most of it can probably be reused. I'm not an HVAC expert but I'd expect the lines and the evaporator would certainly be reusable if they use similar refrigerants. It should be possible to convert just by adding extra valves in the existing outside unit but installers may be unwilling to do that and you may want a new variable-speed compressor for added efficiency.

If somebody is out buying an air conditioner and one of the boxes in the store says "also heats, 5x as efficient as traditional electric heat" they might want to check it out.

  1020. Where I live, evaporative cooling is used, ironically, to make rooms warmer in the winter. In the winter we put wet paper towels over thermostats in places like schools and offices where the setpoint is remotely controlled. This cools the air by the thermostat so it thinks the room is colder than it actually is. The heater is run until this cold area reaches the set temperature, at which point the room itself is warmer than the too-cold temperature set by facilities management.

Upgrading to an eight meg card I could run 1280x1024 and see three times as much of a web page at once.

  1022. If you have a high-quality PSU I'd say 60% of its capacity when your PC is fully loaded is a good target. I think the important bit is keeping its capacitors nice and unstressed. I can't agree with you on powerstrip quality. It's just a bit of wire and plastic, there's really nothing wrong with the cheapest one. The only functional difference is surge protection, but that function is best served primarily by a good SPD in your main electrical panel.
    1
  1023.  @lunsmann  @lunsmann Bad power can certainly be an issue, and fortunately it is not an issue where I live. A straightforward power strip will have absolutely no effect on power quality, I'm assuming you're actually referring to needing a good surge suppressor. 99% of them are just MOVs across the power line and I wouldn't put too much faith in them. As I said above it's better to use a beefy surge protector where power enters the premises and optionally use desktop surge strips as supplemental protection. UPSes are indeed nice to have but shouldn't protect hardware, only data. As another note I think here in 120v-land there is a much lower risk of damage from power surges than in 230v countries. I've never paid extra for any surge protectors (but do have several old ones in use) and haven't had any computer issues from power surges.
    1
  1024.  @lunsmann  If touching the power strip shuts down your PC then that is indeed a problem and should be replaced. Besides data loss the poor connection could heat up and potentially start a fire. It's true that it's the amps that kill, but only around 50mA is needed to be deadly and even the smallest 2.5A circuit provides 50 times that without flinching. Due to Ohm's law a 120v shock will only give half the current of a 230v shock. Other factors like plug design can play much more of a role in electrical safety, American plugs really don't have any features to protect from shocks unlike most European ones.

  1026.  @mernokimuvek  While not necessary polarization is still nice to have with electronic lamps so the fuse goes on the live side. And it's hard to accidentally put your fingers in a light socket and get shocked. US style plugs are much more of a shock risk than light sockets.

  1033. The lights are connected in parallel, it's just the wires themselves which are in parallel. Daisy chaining general-purpose power connections is perfectly fine. Star connections are only needed in specific applications, and even then it's usually just the ground. I don't see the point in mentioning that 10 4 amp lights would draw 40 amps. Zack (his name isn't Jerry) is only wiring two headlights. Part of engineering is knowing what the requirements are. There's no need for the lights to all be perfectly matched. If there were giving each its own cable to a common star point isn't enough, you'd also need to match the length of each wire. Where I do agree with you is that it's not great to wire all the lights on one fuse. But I don't say that because it makes it easier to identify which light failed, I say it because it reduces the chances of a single failure causing all your lights to fail at the same time when needed for safe driving.

I suppose it's possible that they strip the data and then regenerate it but I find this unlikely.

If it's humid moisture will condense on the outdoor coils. If it's also freezing outside the condensation will ice up the coil and the heat pump will periodically need to spend time and energy defrosting.

  1053.  @elzafir  Installed Ventoy on an an i5-3570? I'd expect it to work there as that generation almost always has UEFI support. It's first generation Core i systems and earlier where I would expect problems due to them usually lacking UEFI. If you're talking about Windows 11, I would also expect that to work, for now. As it's not officially supported MS has every right to increase the actual requirement and they've already done it once already. A recent update left Core 2 systems with W11 unable to boot.
    1
  1054.  @elzafir  Well like I said MS recently upped the requirements to boot to a first-gen Core i CPU. That's only one architecture behind your 3rd gen so if they bump the requirements again you'll likely be unable to boot. I hope it's not something you rely on.

Ventoy isn't hard to use but I would not recommend it to beginners.

I've never had a problem with the electronics getting cooked; I've done autopsies on my family's burnt out CFLs and without exception it was the tube itself which had failed. The only early failure I encountered with CFLs was in the bathroom where they were always short-cycled. And even that was probably just because of the instant-on "feature". We have an old-style non-twisted CFL with proper programmed start and it still works fine after 16 years of frequent use.

  1059.  @TurboGoth  Yes, that is what I said. Thermal throttling on non-EIST processors was done by skipping clock cycles. SpeedStep on P4s and Core 2 CPUs is controlled by the OS writing frequency multiplier and voltage values into CPU registers. On an unmodified system the ACPI code will surely tell the OS to reduce the clock and voltages. If the OS disobeys this I don't know if these CPUs will override the programed values or if it will only clock skip like the earlier CPUs. On the newer CPU generations with Turbo Boost I do believe the CPUs downclock and downvolt themselves when they get hot.

  1064. There is, most telecom equipment operates from 48V so many servers can be ordered with 48V PSUs. But note that this isn't as useful as it seems at first. It only skips the conversion inside the UPS, the server PSU still needs to be isolated to prevent ground loops. And then during normal operation you have an extra AC->DC in addition to the normal one. The only way I can see it working well is if your server supports redundant PSUs of two different models. and can be set to use the normal AC one if possible and only draw DC if needed.

  1069.  @Solid_Snake99  I don't understand all the emojis. I can tell you that a SEER of 10 (the minimum from 1992) is equivalent to a SCOP of 2.92. A SEER of 7.33 is a SCOP of 2.14. SEER is for cooling but if you meant HSPF (the equivalent for heating) the conversion to COP is the same.
    1
  1070. Where are those temperatures coming from? Modern heat pumps usually maintain a COP of 2 down to 5F outdoor temperature. If you need heat strips it's because you need more heating.

  1077.  @Science1144  Not quite. When the indoor temperature is set back lower than the design temperature your heat losses are lower than expected. This means the 100% sized furnace still has some extra power to bring the temperature back up even on the coldest day. And on the other 362 days it can do this without struggling. And this effect is even greater with heat pumps. Heat pumps actually output more than their designed output when the indoor temperature is low. Having said that, it's fine (and I'd argue a good idea) to oversize a little bit, perhaps 15-25%. This can also provide insurance for possible changes in the building's performance. Up to 150% sizing generally doesn't hurt performance. If the installed equipment is over twice as large as the calculated worst case there better be a very good reason.

  1079.  @Tkozuh  Panels are surprisingly strong, they're made to withstand hail. It's normal for panels to survive while everyone else's asphalt roof is ruined. If a panel does break within 25 years it's probably covered by warranty. If not, a single panel is $150-400 and easy to swap out.
    1
  1080.  @Tkozuh  If hail is regularly going through everybody's car windshield then solar panels are probably a poor choice of economic investment for you. Standard panels are only made to withstand direct hits from golf ball sized hail. If you just want to play around with the technology you can throw together a basic usable off-grid system for under $500. That's less than the latest smartphone or gaming console.

  1081.  @Tkozuh  I was talking about a mini-system. I'm sure you can get a 300W panel, charge controller, 1kWh battery, and cheap inverter for around that much. It won't run a full house but it's enough for decent lighting and/or a small refrigerator. And I'm not sure where your $15k panel-only price is coming from. 7kW of panels should have no problem generating 30kWh/day on an average winter day. 20 panels * $200 each = $4000 in panels. I haven't checked recently but I don't think panels have gotten 3x as expensive in the past year or two.
    1
  1082.  @Tkozuh  The main point of the mini-system is to have fun experimenting. But it's also useful because it gives you a decent source of electricity when the grid's down. You can also take it with you if you go tailgating, glamping, etc.

  1083.  @Tkozuh  You need capital, not income. An important difference. You can have plenty of money now but might not be able to rely on future income. Or you might even use bank capital. If rates are favorable you can finance the system and have monthly payments less than the electricity savings. You'd be saving a little bit every month but then once it's paid off the electricity would be entirely free.

  1091. In America white is neutral and all colors (except green) are hot. White is the color of the insulation before dyes are added to the mix, so it makes sense as the color you use when you aren't adding voltage. Really though, all 120v countries have white as neutral and black as hot. This is a 120v only device, so why would it be using 240v colors? Not just any 240v colors, but 240v Aussie colors. It seems like Australia is the only country still using black as a neutral. Everybody knows everything's upside down in Australia, why would you accuse Americans of being backwards?

  1094. Hey Alec, don't you usually put the corrections in the pinned comment? I have some fodder for you: 1. (9:44) You refer to a "sixteen pin chip" but I can only find an eighteen pin chip. 2. (10:05) As has already been mentioned, TRIACs turn the current on, not off, midwave. 3. (6:59) The ring in the tube circuit is insulated. On line 47 of the first column of text in the patent, it is specified that "the base 5 is made of ceramic, glass or some other insulating material." 4. (13:22) You couldn't connect the sensing electrode to a refrigerator because the refrigerator is (Hopefully) grounded. 5. (7:57) I doubt the tube circuit would have used 10-20 watts when idle. A tube similar to a 12AX7 could be used, which has a heater consumption of only 1.9 watts and a max anode dissipation of 1 watt per section. I would expect closer to five watts for the power consumption of the entire circuit. As a side note, the English WIkipedia page 'Touch-sensitive lamp' has seen significant improvements since this video has been published.

  1098. You can only add an outlet at the switch location if it's fed from the switch (or is post-2011 NEC). Oftentimes switch boxes will have hot and switched hot but no neutral. Actually now I realize even if fed from the outlet side you can just rewire it there. But then you have the problem of not having a switched light which is code required.

  1101. Cogeneration is another way to provide heat, and can work well with heat pumps. If power plants have 44% efficiency, the remaining 66% of energy is waste heat at the power plant. If this heat is piped into homes instead of directly into the atmosphere we'd have less need for a heater in the first place. I just don't know why this is so uncommon, it seems so obvious. It's not like it's too hard for us to extract the extra energy, that's exactly how the heating on a typical car works.

  1109. If you're wiring out to a shed I would suggest going for a multi-wire branch circuit at the very least. Not to go into the details here but it's effectively two circuits but only 33% more copper and would also let you have some 240v loads. Also I think you should be able to do what you suggest running conduit under the sidewalk if it is all on your property. Check with laws and codes but I doubt it would conflict with the sidewalk easement.

Since your table saw is electric you could have the dust gate's power supply connected inside the saw to avoid the external ziptied cable.

  1136. Let me chime in here. A year or two back I looked at the installation instructions for a similar Siemens EVSE. If I recall correctly it is required to be on a GFCI-protected circuit if installed outside but not if installed inside. For DC fault currents I believe the car itself has ground fault detection on the high voltage DC system, opening the contactor and disconnecting the battery if a fault is connected. I don't know where else DC fault current could possibly come from.

  1140. Are you actually looking at full COP at different operating points? COP at 5F (-15C) is usually 2 here. This includes blower power (if European ratings don't then your ratings will be higher for the same unit). We also use "older" refrigerants in the US. We're supposed to switch to R32 any time now and AFAIK Europe is already moving away from that.

  1141. ​ @natehoy6924  Before the 2011 NEC you didn't need a neutral at the switch location. This would be the usual case if the power is fed at the outlet side. However if you are wired this way you change the connections at the outlet and then the previous switch location is a permanent on power point.

Worst case they throw up a nag screen when they think they're out of ink but they'll just keep working if you refill them. My advice is to only get a printer if you can get cheap aftermarket cartridges for it. Avoid cartridges with built-in printheads if you can because the aftermarket 'new' ones are just reused OEM cartridges and after a certain point all will be out of life.

Anything made in the past 30 or so years is going to be computer-controlled. Unless it's already malfunctioning you can't cause any damage by commanding a downshift.

  1192. I think this is a bit unfair because different environments may have different results. I mean differences in relative speeds, obviously a Threadripper is going to be faster than a 386. Language 1 could be faster on Zen than language 2 but on Conroe it could be the other way around even with the exact same binaries. Different compilers/interpreters could also make a difference. Obviously I don't expect you to test every possible computer in existence but it would be interesting to see a few different types.

  1213.  @delavega92  If the power plant is solely gas-powered you probably end up with 30-40% efficiency by the time it enters your home as electricity. Multiply that by an average COP of 3 and you end up with around 100% net efficiency. It's about even. The real benefit comes when some of the electricity comes from other sources. As the grid becomes cleaner the heat pump system becomes better but the furnace will be stuck burning gas at 96% efficiency.

  1215. Higher voltage power electronics are also more expensive. And for a car you usually don't go thinner than 18 gauge because then the wires would be too fragile. For anything under 500-1000 watts this would mean you wouldn't be saving any copper.

  1216.  @ccoder4953  That article is wrong in its assertion about needing eight circuits, that's only if you have tons of built-in appliances.

  1217.  @chrisarnone7896  Linemen need to ground out lines before working on them. If they do this and someone is backfeeding there will be a bit of an arc and then your equipment will be forced to shut off (either gracefully or by self-destructing). If you are trying to backfeed an entire town this will happen before the lineman arrives but if there is an open circuit fault near you your equipment could possibly still power you and a few neighbors.

  1219. Except the oversized furnace has a more power hungry fan. Assuming ECM (brushless BLDC motor) blowers, the same size cabinet, and the same ducting, the 2x size furnace need twice as much airflow and thus 8x the required blower power. So 12hr*600W vs 24hr*75W per day. The "fan laws" with cubic response really favor having smaller forced-air systems.

  1229. Since a heat pump is 90% the same as an AC unit it should last just as long. Calendar life is less because you will run it in the winter instead of just the summer. Modern inverter units should have longer life than a conventional AC on the mechanical bits but the electronics could fail. Fortunately electronics are cheaper and easier to fix/swap than the sealed system.

My gut feeling is most failures would be on parts which are separate from the engine.
    1
  1231.  @ddnmd  My point about repairs is that all of the items you mentioned are either parts specific to the gas engine or are also present in electric ones. The are practical reasons to go with gas over electric (namely range and weight) but I don't see trailside repairability as one of them.

  1232.  @blahorgaslisk7763  The jumper is not on PCs anymore but Chromebooks have a hardware write-protected area of the flash chip. The protected block verifies the main firmware and might also provide a recovery mechanism. On modern PCs the chipset has hardware fuses which can be burned with a key to only allow firmwares signed with a specific key. To run rogue firmware you (theoretically) need to replace the chipset. Lately this has caused some trouble, AMD Epyc moved the chipset (and the firmware verification) onto the main CPU. If a CPU is installed in one motherboard it may be burnt with that manufacturer's key and when placed in another brand of system it won't boot.

The largest resistance heater that you can possibly run on a standard household outlet is about 6000Btu/hr.

Obviously your electric rates will go up significantly, but your existing heating system also costs money to use. I'm also in MA and by my calculations on current utility rates a heat pump should be about 30-50% more expensive than gas if you use it the entire year. Since heating oil is more expensive than gas your heat pump should be saving you money if it's properly sized and installed.

Of course it took a few years for each of these to become widely adopted. Practically speaking (on the Intel side) the 20 pin was used on motherboards from the second half of the classic Pentium through the Pentium 4s with pins and the 24pin is on motherboards with the LGA sockets. My HP desktop from 2007 has a 24pin motherboard but the power supply it came with only has a 20pin, with the four on the motherboard empty.

  1256.  @ChaJ67  There are inverters which will directly input the pack voltage and directly output 120 or 230 volts without an extra conversion stage. If you do go with a separate DC-DC supply feeding an inverter then it's probably better to do 48 volts. I would definitely avoid 24 volts if you plan to ever go over 2 kilowatts.
    1
  1257.  @ChaJ67  If you are going to tap into the HV system to feed a 24v supply you may as well bring the HV out directly into a suitable connector so you can attach different converters. When I first looked into it higher voltage inverters were quite rare. But nowadays there are relatively inexpensive "hybrid" solar inverters which may be able to accept the Prius HV directly on a PV input.

If an individual came in with a bag of cans they'd weigh it and pay you. In this case if I'm not mistaken the defendants were allegedly bringing entire trucks full of metal and lying about the contents to the state's online database.

  1274. The fact that you only hear about explosions is because they're unremarkable. We have CO and gas detectors so if something were to happen we'd be able to open the windows and evacuate if needed. And the problem with the battery backup idea is the power draw. The tiniest modern furnace probably draws 200 watts. To last all day you'd need 4.8kWh of battery which on the lowest end is $1000. It would probably end up doubling the cost of the unit. It's just better for them to come without backup and people can add their own backup if desired.

  1275. There's no such thing as a "400% efficient" (really COP of 4) heat pump, that's just a marketing average. Hot and cold side temperatures affect the actual capacity and COP of a heat pump.

  1284.  @Ravenous  I KNOW my PC uses under 200w worst case. My quality 350w is sufficient. I certainly feel more comfortable with it than I would a cheap 600w supply.
    1
  1285.  @Ravenous  Well, I don't know what you'd consider real world then. A GTX 1050 uses 75W, a desktop CPU is usually under 100W, and other things should use under 50W. That's 225W which is well within the ability of a 350W PSU. Not everybody is using a crazy gaming system. I'd agree 600W is probably the minimum for a gaming rig with high power GPU but not everyone needs a top tier card. Really all I'm saying is do your research before you buy instead of subscribing to blanket statements.
    1
  1286.  @Ravenous  That's why I allocated 50w for 'other' in my quick estimations. I'm not saying you should buy a smaller PSU if you're building a gaming PC, just that you don't necessarily need a 600w supply. If somebody already has a decent PSU they don't need to go and buy a bigger one unless they actually need it. My only issue was with you suggesting everybody needs 600w when this is not the case. You may, and many of the other viewers may, but this does not constitute everybody. Most PCs are not gaming PCs. And BTW, I first ran Minesweeper on a system with a 36w power supply and I've run Tetris on a system with a 1.6w supply. Out of curiosity, how big of a PSU do you have and how much power do you actually use?
    1
  1287.  @Ravenous  I was not trying to be rude but I see how it could have come off that way. Systems can differ but I thought 50w was reasonable for these components. In a recent LTT video they showed a system with idling at 30 something watts from the wall. That also includes the CPU, GPU, and losses inside the PSU itself. Maybe that was 25w when you exclude CPU, GPU, and PSU losses. Obviously that would increase with a loaded system but I'd figure it would be less than twice the idle value. It doesn't really matter because I was just looking at rough numbers and again different systems will be different. For you 700w seems like a nicely-sized PSU.

  1290. If it's actually slower you probably have an issue with the cooling system like dried up thermal paste. But there's a greater chance it just feels slower because you're using it for more demanding tasks. In recent years modern websites have started needing more and more CPU power.

Basically anybody can make a fake login but only the system administrator can make one which survives the SAS.

  1304.  @Asmodes_Reynolds  Is that true? I would think sufficiently large supercapacitors would be huge, not to mention less cost effective. I'm not an expert in the field but I do know the new Toyota Miara uses batteries as the buffer. Battery life is a potential but most modern EVs have water-cooled batteries to maintain proper temperatures. Most people get over 100,000 mi without much degradation. Unless you are very unlucky you shouldn't need more than two batteries. And parked EVs can also be used as grid storage (at least in the future), making it easier to mix in more renewables. Also degraded EV batteries can be used for grid storage, giving them a second life. And I definitely agree about nuclear.

For better performance you probably want one with more smarts. It's better to have multiple zones but I would imagine most would have no problem operating with a single zone.

  1307.  @cerburusmori  For a transformer to be efficient you need a strong magnetic coupling. Regular 50/60Hz transformer cores are made of stacked E and I shaped iron laminations. If you assemble one without getting everything properly tight the idle current will be higher due to magnetic saturation. For something the user plugs in by hand this is a no-go. There are probably ways to ensure this doesn't happen but in the end you'd end up with a massive plug costing over $100 compared to the compact 69 cent traditional outlet.

  1325. If the power strips are up to spec that isn't an issue. You would eventually reach the point where a short circuit wouldn't trip protection but at that point the current would be below the rating, hence no fire. Any increased fire risk is simply from having more points of failure.
    1
  1326.  @NeneExists  I still don't think the risk is any worse. If you have a 20 amp breaker then it will allow 19 amps to pass unimpeded. You could have a legitimate 19 amp load or a short circuit at the end of 50 power strips which draws 19 amps. To the connections in the circuit there's no difference.

  1339.  @PlaystationMasterPS3  TLDR 16mpg. I was wondering the same thing so I'll run the numbers(even though I'm a year late): Honda EU2200i runs 3.2 hours of rated load on its .95gal tank A level 1 charger draws 80% of that so runtime should be a bit greater. So 1 gallon of gas probably will run the charger for 4 hours. Assuming the car charges at 4mph that means those 4 hours get you 16 miles. 16mpg is far from great but it's on par with large SUVs. As an emergency range extender I'd say it's not too bad. I'll also run the numbers for a large Honda EB10000: 8.19gal gives 5.4 hours of 9kW load That results in 5.4hr * 9kW / 8.19gal = 5.93 kWh/gal Multiply by 4 mi/kWh and you get over 23mpg A common L2 charger will only draw 85% of the generator's capacity but that still gives over 20mpg.

It works well for me, although I have been using Python for some other projects. And side note, is the Microsoft compiler really that slow? The Borland compiler would probably take the same amount of time to compile this demo on my Pentium 166MHz as the MS one took on your Threadripper.

  1344.  @christopherdahle9985  I doubt your central office has the same old switchgear as the Connections Museum, they're pretty confident they have the last remaining panel and 1XB switches. 5XB is much more plausible. And running a magnetron on PWM? It would technically work but my understanding is magnetrons electrically behave like LEDs (but also have filaments). Meaning they have a relatively constant voltage drop when running (a few kV) and rely on external current limiting provided by the transformer and the doubler's capacitor. What I'm saying is high-frequency PWM is somewhat impractical as it would interfere? with the original current limiting. There's a reason microwave manufacturers use low frequency (0.067 Hz in my case) PWM instead.

I haven't been able to find an answer to this question but it seems like it could be very important when provisioning cores.

  1359.  @planesandbikes7353  If you have a decent carbon tax it doesn't make too much sense to require complete removal of the old system. In Massachusetts one of the rebate requirements if gas is still in place is that the thermostat automatically switches from HP to conventional when needed. I think this is a good move, it means you aren't left juggling different thermostats.

Most of it will go to the heating system (and the rest heats the house indirectly) so divide by your furnace efficiency to get the actual heat output into the home. The gas bills around here show average gas usage per day as well as average outdoor temperature during the billing period so it's easy to do the math.

  1392. I haven't compiled a kernel recently but does it really take 45 minutes? IIRC that's about how long it took to compile a 2.6 series on a Celeron 466. I figure you're running at least a 2GHz dual core so I would expect it to be much faster.
    1
  1393.  @afedorov3  I think that CPU is about 15-20 times as fast as the old Celeron I'm using for reference which compiled an older kernel in the same amount of time. So in the past ~15 years of software progress either the kernel is 15 times bigger or the compiler is 15 times slower. Software bloat clearly isn't limited to lazy web and app developers. This comparison is also assuming you have an SSD. If you're compiling on HDD you could be spending a decent amount of time on IO waits and not fully utilizing your CPU. You'd also want at least -j 3 or -j 4 to maximize CPU utilization (RAM permitting) but if you're a Gentoo user I'm sure you know that.

  1394. In terms of plain electric heating everything is 100% efficient, the wattage is exactly equal to the heat output. The difference is how the heat is utilized.

  1395. If you have two fixed-speed systems the lower-capacity one will have a smaller motor. Assuming the same ductwork in each case the blower in a 2ton setup will theoretically draw 1/8 the power of the one in a 4ton setup. Considering the increased runtime that's only 1/4 the blower energy consumption. I believe there's a similar (but lesser) effect with the refrigerant linesets, the slower you go the less energy it takes to move a given amount of fluid.

  1412. A properly functioning refrigerator won't trip a properly functioning GFCI. Either there's some leakage current in the fridge (most likely in the defrost heater, possibly from damaged winding insulation) or the GFCI is false tripping. I haven't seen this sort of false tripping myself (we've run a freezer on a GFCI for the past 18 years without issue) but apparently some GFCIs are sensitive noise on the power line. But this still doesn't explain Dave's GFCI tripping. With isolated power supplies there's no way that should happen. I could understand the cheap replacement supply failing but it not Dave's bench PSU.

  1417. @MacroAcc I disagree, while multi monitors can reduce the need for workspaces and vice versa they most definitely do not eliminate the need. Multi-monitors (or one huge one) is needed to see more than one thing at once and workspaces put more than one thing in the same spot. It's not uncommon for me to have four or more workspaces active and four monitors are expensive and take up too much physical space.

  1421. It means your system lacks proper electrical grounding. This is bad, if a fault develops it means you'd get a dangerous shock instead of a slight tingle. The easiest thing to do is to try a different power cable. If that fixes it, great, and destroy the bad cable. If that doesn't fix it, your wall outlet is probably ungrounded and this should be corrected by a competent electrician.

If filled with hot water directly from the tank that's enough for at least two loads on a 50 gallon tank.It's only a problem if you have a large laundry day. If you rarely do more than one load at a time it's a complete non-issue. Also the modern washer will take longer per cycle than the hot air dryer, leaving off-time for the water to reheat.

  1436. To be pedantic what these appliances include is most likely a chassis wiring diagram instead of a schematic. Most of the components are contained on control boards and I doubt you have the schematics on those. Regarding these being more dangerous, that's likely part of why they include service information. Improper service (for example: bypassing a broken microwave safety interlock or flame sensor) could result in actual unsafe conditions and companies don't want their name to be tarnished by this.

  1439. Why don't you want a furnace running for 24 hours? Also the design metric is so it will run full-time for the coldest hours of the year. Once the sun comes out the load will reduce, meaning the furnace really will only run 12 hours at most, and once again this is only once or twice a year.

  1443. You should really have some sort of back-up / supplementary heat. This is standard in central heat pumps. If the heat pump can't operate the thermostat will automatically turn on emergency electric heat. Some mini-splits can have this added as an option. I think it's a no-brainer because the parts are super cheap. If you never need the emergency heat it won't hurt efficiency, but if you do need it you'll save the cost and inconvenience of a hotel.

    1
  1454.  @andersjjensen  I wasn't thinking of interrupts, for some devices that could indeed slow things down. Although it's seldom used I'm thinking the 386 lets you handle interrupts in ring 3 without a context switch. I'd need to review the details of how a Task State Segment, Interrupt Descriptor Table, and related structures work. It seems you can handle software interrupts this way, and I would figure hardware interrupts also might.
    1
  1455. ​ @andersjjensen  The interrupt table eventually eventually points to a CS:IP pair, even in protected mode. If the code segment is a ring 0 segment it will be privileged, if it's a ring 3 segment it won't be. If the handler's CS is the same as the currently executing code segment no context switch is necessary. Really if the TSS is the same no real context switch happens. The x86 CPUs only have one interrupt pin (2 if you count NMI). When an interrupt comes in it will use a special bus cycle to ask the PIC chip which interrupt number to call. These chips can be nested (like on the AT) to to get "infinite" HW interrupts on older CPUs. Once an interrupt number is chosen I don't think the CPU cares if it was hardware or software, at least this is how it works in real mode.

  1461. ​ @BrodieRobertson  For some reason I was under the impression Debian was dropping 32-bit x86. Maybe it's something they were considering at some point. Or it's just that I'm annoyed they bumped the requirements to a 686. Close to a decade ago I had an install running on an old K6 laptop so that bothered me. Fortunately for people still using these older systems as daily drivers the retro value has increased so that you could sell one and buy a faster Pentium 4 or newer system and come out ahead with a few dollars.
    1
  1462.  @BrodieRobertson  On a practical matter that's debatable. It's easy to find updated user software for Windows 7 but not so on EOL Linux distributions. However Firefox seems like it will probably drop W7 support next year while the current Debian stable will go far beyond that so it's a moot point. There are some systems which will run Windows 7 but not current Debian where this would be an issue except AFAIK they don't even meet 7's official minimum specs so nobody in their right mind will be using them for real work. However Steam is a different story. Some games work just fine on 7 but not or not as well as on newer OS. If I bought a game online in 2012 which required Windows 7 but now I can't run it because Steam no longer runs I would be far from happy. Hopefully Valve provides some sort of legacy client so people can continue playing their already-bought games without resorting to piracy.

If you have a switch at the wall and on the lamp each of their switches becomes an independent control more akin to a 3-way (called 2-way in other countries) setup. You'd need to remember to put everything back to ON but this is probably easy to get used to, at least easier to get used to than what Alec is doing now.

  1466. 8v on a 3S battery should be enough for any decent BMS to permit a trickle-charge naturally (and now I see you said that too).

  1478. Missing piece: find a way to get the waste heat from the generator's engine into the house. Perhaps some sort of heat exchanger on the exhaust. A 5kw non-inverter generator might need 1000,000Btu-hr to run at full speed. An inverter one will be a bit less but when on generator it would massively cut down on fuel used when powering the heat pump.

  1484.  @Irthex  Heating is determined by I²T, current squared times time. I'm not sure how it works in Europe but in the US our standard plug is nominally 15 amps. At full capacity we can only use it for 3 hours because of heating but if we only use 12 amps or 80% capacity we can run continuously. Do you have electric space heaters available where you live? If so, check their wattage. That's an amount which can be drawn continuously for an extended period of time.

If they know when you load the page and they know how long the ads are they also know when the ads should finish playing.

Then we would be left with an annoying countdown if we skip ads.

  1486. It sounds like you could make use of an air-to-water heat pump for whole-house heating. Most are designed to heat water to 120F/45C which is likely enough for your existing radiators to put off a decent amount of heat. If you need more heat output on a cold day then switch the water system back to one of your boilers. If you want more whole-house heat pump than this allows you could replace some static radiators with fan-operated ones. These output much more heat at a given water temperature. You could also wait for more high-temperature air to water heat pumps to become available.
    1
  1487.  @repatch43  If you have appropriate radiators/indoor coils you can cool with an air to water heat pump. Even with the current inappropriate radiators you can get a small amount of cooling, you just need sensors to prevent condensation. Unfortunately this also means no dehumidification, I don't know whether or not that is a problem in your area. I had mentioned turning down the boiler temperature and this has another benefit. Gas boilers (and I suppose also wood boilers) operate more efficiently with lower water temperatures. This is needed to get the full benefit of a modern condensing boiler. If your boiler is non-condensing then don't do this because flue gas condensation will cause problems if the system is not designed for it.

For a better number you should look at the total miles driven and the energy consumption of EVs per mile. I did the math a while ago and IIRC switching everyone to EVs would only add around 10-20% to the total electricity usage.

  1502.  @daveh6356  I was also talking about a thermal circuit. The separate electrical meters is because each tenant would get billed for their own heat pump's usage. It would be more efficient to have one giant heat pump feeding both a hot water loop and a cold water loop. Each unit's heat exchanger would select the appropriate pipe depending on whether it needs heat or cooling. The downside of this more efficient approach is that it becomes next-to-impossible to fairly bill each tenant for their share of the usage.

Using PWM dimmers to change colors will also produce some noise but this is probably less and can be managed by changing the slew rate. LEDs should also be immune from noise but the data lines for addressable ones would be most likely to be susceptible. Shielded cables would probably help with that.

  1538.  @jeffa847  A few years ago I ran our early 1970s Whirlpool upright freezer on an energy monitor for a week or so. It was about 170 watts at 50% duty cycle. Assuming the same usage year-round this comes to just under 750 kWh/year. It's worth noting that this measurement was during winter in an unheated basement, the actual yearly usage is probably greater. I think the bigger issue is if a fridge isn't running well it might be using more energy to maintain temperature. Our 1989 Kenmore fridge that came with the house seemed to be running too much and after switching it with the spare 1997 GE there was a noticeable drop in household electricity usage. Side note, unplugging a fridge when it's running is perfectly fine, that's what the thermostat does. Turning it back on is when you need to be more cautious.

I also don't know how a pot could go from induction compatible to non-compatible without massive physical damage. If the steel insert is that thin I don't think it would work at all. It's worth noting that some very advanced induction stoves can work with aluminum/copper pans.

  1549. Admittedly the gas heater that needs 600-700 watts of electricity to operate will output more like 22kW, a little more than your 3.4kW. If you actually need that much heat your heat pump will use more like 5kW. Still not a very big deal, 5kW happens to be the rating of most portable generators around here. Plus if you use a generator it's possible to set up a heat exchanger to capture much of the engine's waste heat.
    1
  1550.  @Ruben9505  You're missing my point. I'm not saying that anyone needs a 22kW furnace. I'm saying that the gas heat uses less electricity per heat output. A more reasonable 6kW furnace would probably need under 100 watts if built with modern parts. If your goal is running a heating system off batteries then the furnace is simply a better option. Of course this is a big game of "but sometimes". Anybody designing their main heating system for power outages at the expense of normal operation has some messed up priorities. Side note, what sort of heat pump do you have? The absolute best heat air-to-air pumps here in the US reach an average COP of ~4.4. If you're getting a COP of 4.7 in a colder climate it must be something else. Is it ground source? That's usually not a viable option here.
    1
  1551. And that's why you should have a Manual J (or other heat-load calculation) done before installing a new system. A heat pump sized for 90% of your heating needs is probably good. In the other 10% the heat pump will continue to run while the resistance heat only provides the difference.
    1
  1552.  @douglasengle2704  Utility rates vary greatly throughout the country. Here in Massachusetts a heat pump is always more expensive to run from the grid but we have some of the most expensive electricity. In places where electricity is 12c/kWh the heat pump wins big time. If you have solar panels you have free electricity during the day, making heat pumps more economical even when grid electricity is expensive.

  1554. I think there should be more of a focus on cogeneration. In a large-scale system you burn fuel to generate electricity, but harness the waste heat to heat buildings instead of just heating the environment like a regular plant.

  1555.  @il-conte  It wouldn't be a typical portable generator, that would be a bad idea for many reasons. It would be a more purpose-built range extender with a constant DC output of maybe 20-30 kW. Charging time doesn't matter because you drive with it running.

  1558. A gas tankless water heater would definitely take a few seconds to start. Electric ones might be an imperceptible delay. But with a hot water tank there's usually some heat conduction into the outlet pipes, meaning it would be a bit warmer while you wait.

  1559. I haven't heard of the valves needing any maintenance. Even if they need a tiny bit of maintenance they are definitely the way to go for centrally steam/water heated buildings. The best part is that they offer proportional control instead of the on-off of a traditional thermostat.

  1564. Any car can do 0-60 mph in about 2.74 seconds if in a vacuum. The secret is a gravity assist. The annoying bit is that the steeper the slope you're rolling down the less traction you can achieve. This could be an interesting topic to explore. If I'm not mistaken, there's a linear tradeoff between the two, so maximum acceleration would be achieved at either level ground or in freefall (depending on the tires), not at some downhill slope. This is again ignoring some physical factors including wind resistance and shifting weights. I don't know how it would play out in real life.

  1579. I think the main problem hindering W-VHS adoption was its timing and the complete lack of HDTV outside of Hi-Vision in Japan. By the time we got real HDTV in the West it was all digital and D-VHS was the way to go. But that was still near-zero adoption. HDTVs only reached 10% adoption in the US in mid 2007 and by that time both optical formats had been out for a year.
    1
  1580.  @mndlessdrwer  From what I read recently Japan's Hi-Vision system required 4x the bandwidth of regular TV and was only ever carried over satellite TV. Digital HDTV, on the other hand, requires less bandwidth than regular TV, with multiple stations often being carried on one carrier. I'm sure the US could have managed an analog satellite HDTV system but it would surely be more expensive to distribute a signal throughout a geographically huge country than a tiny one. The claim that HD was squashed in the US by the distribution companies wanting to sell pre-recorded media doesn't match reality in my opinion. We had the ability to record HD onto D-VHS before D-Theater precorded tapes came out, and we had hard drive DVRs before HD-DVD and Blu-ray.

  1591.  @peteengard9966  I'm pretty sure most EVs don't use LiPos, I believe they usually use cylindrical cells with liquid electrolyte. There are tons of chemistry variations like ICR, IMR, NCM, and the very different IFR. I do agree that EVs aren't for everyone with the currently available technology. But the tech's already much better than you seem to think. It's other factors like cost, manufacturer unfriendliness, and added antifeatures which make them less attractive.

  1594. The original interface was most common on old analog car radios where they were used for presets. You want to minimize time spent dialing in a station when you should be driving. Since old car radios were usually AM-only there was no need for a mode switch. In terms of implementation, oftentimes it was all mechanical, pressing the button would physically rotate the tuning knob through a few levers/cams/pulleys/etc. Sometimes it was interlocked electrical switches which would switch different tuning capacitors into the circuit. After car radios went to digitally controlled tuning in the 80s the implementation of presets was obviously greatly simplified.

  1595. That's (usually) not true. Air conditioners are designed to cool to 75F from whatever your area's 99% high temperature is. If it is regularly above 95F your AC will be designed to cool more than 20 degrees. A slight oversize to 125% should be fine. It's usually only considered a problem above 150%.

  1600. If electricity is only 3x more expensive than gas then a heat pump will cost around the same to run as a furnace. I don't know about the entire market but here in Massachusetts it sometimes gets below -5F. We need a heating system that won't quit when it's that cold.

  1602.  @kmier2000  I haven't done a full cost comparison but when I checked a basic heat pump outdoor unit was $500 more than a cooling-only unit. The indoor AHU is the same whether or not it's reversible. If all of our numbers are accurate this means a furnace and coil costs the same as an air handler. This is hard to believe because burners and heat exchangers cost money.
    1
  1603.  @kmier2000  I'm taking a quick look at a well-known online supply house. Prices are single-stage equipment, 2.5 ton in a "B" cabinet. Cool-only outdoor unit GSXN403010 $1710 Heat pump outdoor unit GSZB403010 $2245 Air handler AMST30BU1400 $1256 Furnace GM9S960803BN $1647 Coil+TXV CAPTA3022B4 $685 Furnace + AC: $1647+$1710+$685 = $4042 Heat pump: $2245+$1256 = $3501 Furnace + HP: $1647+$2245+$685 = $4577 This furnace is single-stage 96% condensing. A cheaper, less efficient, and lower output capacity GM9S800804BN is $1163.62, only $300 cheaper. This is closer in price but with AC it's still $200 more than the heat pump only. I just realized that AHU does not include heat strips. The appropriate HKSC10XC kit is $225. This brings the price difference down to practically nothing.

  1604.  @kmier2000  I don't think standard residential systems are ever sold whole, it's always separate. Package systems like rooftop units are the obvious exception but nobody puts an RTU on a house. And gas isn't much cheaper. When I did the math a heat pump cost something like 30% more than gas to run throughout the entire year. This obviously depends on local utility rates and to a lesser extent the local weather. In much of the country (possibly even most) heat pumps cost less to operate. For a consumer "net zero" means no utility bills, something that will never go out of favor. Heat pump + solar is the easiest way to eliminate heating bills.

  1611. @tripplefives1402 I'd still want a resistor on the bottom in order to properly ignore any phantom voltages which may be found.
    1
  1612. @tripplefives1402 That's the problem. When you only have the Zener limiting the voltage a 3v input will be presented as 3v and read as a logic high. Really anything above 1.8v will be read as high. This results in no noise immunity. Stray leakage current (like what you'd get from a turn signal blinker during the off cycle) will cause a false positive detection. With a full voltage divider you can increase the threshold voltage so it will not activate until there's enough voltage to actually light a filament.
    1
  1613. @tripplefives1402 A voltage divider is a pulldown. With less current the Zener diode will have a lower voltage which is no problem. You seem to have that bit backwards. I agree the turn signal wires will be floating when not in use but I'm talking about when they are in use. A traditional bimetallic turn signal flasher has the heater wired across the contacts. When the turn signal is active but the lights are in the "off" half of the cycle this heater will pass a bit of current. 2-pin electronic flashers will also pass a bit of current in the off half.

From what I can tell nouveau supports reclocking up through "Fermi" which means the GeForce 400 and older all should work fine. GeForce 500 up to and including the "Pascal" (GeForce 10) should mostly work fine in nouveau, just with reduced performance due to lack of reclocking. The "Maxwell" (GeForce 800 and some 700) are supported by the latest proprietary drivers. So it's only the cards released between 2010 and 2014 which you need to worry about if you're using Wayland.

  1616. I'd like to inform you that your extension cord melted because of a poor connection, NOT from the wire thickness.

  1624.  @WatchesTrainsAndRockets  I agree, there are some things (hardware) which require an actual power-off shutdown. But you're wrong on the other point, the hardware has no involvement with fast startup. The stupid combination of this is that choosing restart won't reset everything, and choosing shut down also won't reset everything.
    1
  1625.  @WatchesTrainsAndRockets  When we say Fast Startup we are referring to the feature perviously known as HiberBoot which is basically using Hibernate instead of a traditional shutdown. In S3 sleep is RAM and not much else powered. Hibernate (S4) is the same as sleep except the contents of RAM are saved to disk and then the RAM is also unpowered. This leaves nothing powered, meaning hibernate is the same as off from a hardware perspective. You can fully unplug a hibernating computer and it will come back up like nothing happened. When you "wake" the hibernating system the BIOS loads the bootloader from disk as normal and then it's the early stages of OS which are in charge of restoring the RAM contents and setting everything else back.
    1
  1626.  @WatchesTrainsAndRockets  S4 is the same as S5 (off) from the hardware POV. You can look at schematics to be sure but I think the only things that even have power at all are the main embedded controller. In most cases you need to fully disconnect power to reset this.

  1627. In my opinion the problem with newer cars is all the other computers. In the early 2000s there were still only a few computer systems and they had a specific function (eg. powertrain, airbags, antilock brakes, climate control are all separate systems functioning independently.) Nowadays a car's computers are all linked together on the CAN bus and there is more potential for problems to have a greater impact. TLDR: Computer engine control good, entertainment system disabling brakes bad. The extreme case: https://www.wired.com/2015/07/hackers-remotely-kill-jeep-highway/

  1628. A lot of those off brand new mini PCs just come with unactivated Windows (and it wouldn't surprise me if some are blatantly pirated). They're already not following Microsoft rules, I'm sure they won't be rushing to implement this new rule either.

  1629. Part of it's the filesystem implementation. Also on Windows you're much more likely to be running a real-time virus scan on each file.

  1630. Unfortunately all of my 10 gigabit ports are on the same card so they're not of much practical use. One thing I'm curious about is whether or not a DAC can connect a 10g SFP+ to a 1G SFP. Such a connection would be slightly less useless for me because my switch has two SFPs.
    1
  1631.  @juhavehmanen8604  Thanks for that. I definitely won't be using this connection then. The 1G SFP ports on my switch are shared with 1G copper ports so I'll just stick with the latter. There's zero benefit to me buying 1G DACs and using these ports when it's cheaper and easier for me to get an extra 1G card and use the copper ports.
    1
  1632. That's neat but I don't really see the benefit of this. For manual override I'd just use a regular standalone switch. If you're using a USB device for the output line I would suggest using a USB-serial chip instead, then you can use each control line as a GPO.
    1
  1633. Relatively little I'd guess. AFAIK the main range reduction in the cold is from running the heater. This will be insignificant compared to the range loss from pulling the non-aerodynamic trailer.

  1634. My first Linux experience was after I found the CD for a dead distro called Freespire at a yard sale. It took what would feel like forever to boot up or launch anything on a Celeron 466 but it was still fun to play with. When I got a newer PC and installed Arch and Xfce I was much happier.

  1635. The given purpose of the lock is that it prevents your computer from booting on a hacked BIOS. How would locking the CPU to a specific motherboard help that?
    1
  1636.  @WooShell  I think you're mistaken. The feature is checking the integrity of the BIOS by using the key which is stored in the fuses. The vendor lock is a side effect because different vendors will naturally use different keys.
    1
  1637. 32-bit Windows XP actually works with more than 4GB of RAM by using PAE. I believe this was usable in the original release but then the use of extra memory was disabled in SP1 due to compatibility issues with drivers assuming 32-bit addresses. Server versions don't have this compatibility fix and will still work with more than 4GB of RAM.
    1
  1638.  @FloydMaxwell  Like I said, compatibility issues. I wouldn't expect it to work with a random old system.
    1
  1639. That similarity is to be expected as both are based on 8080 assembly. x86 assembly (but not machine code) was designed to be mostly compatible with 8080 code. Z80 is a binary-compatible extension of the 8080.
    1
  1640.  @kierank01  It makes sense when you consider that propane is running at over 100x the pressure when used as a refrigerant.
    1
  1641.  @zack9912000  R290 won't be in split systems but it can work great for "monobloc" systems where all the refrigerant is contained inside the outside unit. This also has the huge benefit that installers don't need to work with fiddly refrigerant lines. Instead these units transfer the heat by pumping a glycol solution to the indoor coils.
    1
  1642. Hi, did you consider using thin 120mm fans lying flat on the bottom and blowing up instead of 40mm fans blowing horizontally? There would be some more engineering considerations but I think it might be easier to implement overall. Also, how hot does the table get when it's being used heavily?
    1
  1643. We're almost there. You can get basic 12v 200ah LiFePO4 packs for under $500, that's only $200/kWh. Now I'm realizing that meets your price point exactly. Problem is you still need an appropriate inverter which is at least $1k on the low end. And those cheap components probably don't have all the needed approvals for a fixed installation. For a DIY "portable" system you could definitely get a complete $6k which is not terrible.
    1
  1644. Maybe $4000 for a nice heat pump vs $1500 for a furnace. Installation and markup will vary greatly. Depending on your situation a better comparision might be heat pump vs furnace + AC. A heat pump is probably less expensive than furnace+AC.
    1
  1645. While your old heat pump was way oversized I think you had other problems. Even if only running heat strips it should cost the same as an electric space heater. That might be part of the problem. An old R22 heat pump running in the cold may achieve a COP of less than 1. Your thermostat should have cut it off automatically but it probably wasn't configured properly. You also may have leaky ducts blowing heated air outside. Now that you know 10,000BTU/hr is enough you can get one or two 9k mini-splits and cut the bill again.

  1646.  @TheMrMaxx  Clive does his reverse engineering by photographs. It's easy enough to use a screenshot of the video, no need to send the actual device. I would do it myself but I'm lazy.
    1
  1647. If you're installing enough systems for that to be a concern you should be using unattended setup files to save much more time. More importantly, AFAIK the only thing that changed is the time and warning message. If it wasn't a problem at 20 minutes it's probably not going to be a problem at 15 minutes.
    1
  1648. It's easier for folks not familiar with command line tools. Also Clonezilla will usually be faster because it only copies used blocks.
    1
  1649. I've never heard of a 48 amp EVSE. I've only seen 32 amp ones here in the US. I don't think many cars can charge faster than that.
    1
  1650. If you only need heat 20 days a year it's probably not worth replacing your existing AC with a heat pump. When it eventually needs replacement definitely go for the heat pump.
    1
  1651. I should add that if your fridge is inside a room which is at a fairly constant temperature it won't help at all. If X degrees is the warmest your fridge can be then just set it to X degrees. Overcooling it will cause a greater temperature gradient, meaning more thermal energy will flow through its insulation.
    1
  1652.  @cjay2  I just went into the "Defragment and Optimize Drives" app on my Win10-upgraded PC and it clearly says "Drives are being analyzed on a scheduled cadence and optimized as needed." And the last optimized date on my HDD partitions is November 13. It's definitely working.
    1
  1653. Given how both fuels burn in the same way I don't see why you couldn't have both in the tank at the same time. If the two separate and don't mix then you would probably just need to readjust the lantern as it finishes one type and starts the other. Also I believe the dual fuel lantern is white gas and automotive gasoline. Without the alcohol cup I don't think it would start on kerosene.

  1654. My 'office' desktop has a C2D E6300 and runs great even using its original spinning HDD. I feel no need to upgrade it. My C2D laptops are also great. In fact, my ThinkPad T400 is the first laptop I've had which just felt 'right' to me. No post-C2D laptop has given me the same feeling.

  1655. The second knob could be power level. Real power level with a rheostat, not power cycling like digital ones do.
    1
  1656. The connectors are all recessed so nothing is exposed when it could be live. They also have protection like GFCI/RCD in case something were to go wrong.
    1
  1657. For point 1, dryer sockets are only 30 amp receptacles. If you get an EVSE with the matching plug it won't let you set a charge rate higher than 24 amps. For point 2, get a splitter if you would otherwise need to swap devices. Apparently there smart ones that will disconnect the EVSE when you put the dryer on.

  1658. Intel can easily show themselves above AMD on benchmarks. They just need to take a pocketknife and carve themselves on the backrest of the bench and AMD on the seat of the bench. Do I hear crickets?

  1659. The firewall is a Stateful firewall. When it sees white ping red it temporarily lets the reply back through. The same works for TCP connections, when the stateful firewall sees you create a connection it lets the reverse traffic between the same port pairs continue until the connection is closed.

  1660.  @johncoops6897  True but it's not worth worrying much about. Of those HVAC is the only substantial load and it seems these don't need to work very hard if you're not moving.

  1661.  @johncoops6897  General car electronics are about 300 watts on the Prius. Even if you are using 1kW it's still like you're only driving 3mph. For the HVAC, It's what Alec said.

  1662. That seems like a perfect environment for home energy storage systems. Being paid to charge up is a great deal.

  1663.  @yoice2k  3 phase permanent magnet motor is a type of synchronous motor. There's no slip involved. Sensors and the motor control circuitry adjust the current so there's always the optimal angle between rotor poles and stator magnetic poles.

  1664. It's no wonder those batteries still work. Those "old" batteries have a use by date later than any I have. Most of mine have dates from 2003-2011. Most impressive is probably the batteries in my family's older VCR's remote. The batteries in it are Sharp branded so I figure they probably came with the VCR when it was made in 1990. They were still working when I put the VCR away over 25 years later. Not bad for some cheap carbon zinc cells, although unfortunately they've gone flat since then. The craziest thing? Most of mine are Duracells.

  1665.  @d0nj03  Leg height? You mean like central air conditioning vents? I don't know about these specific units but it's possible to blow upwards, away from the room's occupants. Regarding noise, I expect them to be pretty quiet on the inside. Most of the noise will be outside.

  1667. The kids know that if they get caught doing that they'd be in a lot of trouble.

  1668. A "smart outlet" sounds a lot like an EVSE. In some areas (I think UK for instance) most public charge stations require you to bring your own (standardized) cable. Since the cable is the most prone to damage (both by accident and by vandalism) this should increase reliability.
    1
  1669.  @robertpatterson5937  Maybe it's a bit cheaper to have an ordinary outlet and I guess if it's inside a garage you probably don't need to worry about rain. The benefit of a standard outlet is you could easily charge other things, like ebikes. The problem I see with what you described is the need for an app and presumably also Internet connectivity. I would hope that such systems also have provisions for standard payment methods, such as one kiosk serving many outlets.
    1
  1670.  @robertpatterson5937  But why would the app not be an impediment for residents? Not everybody has an always charged smartphone with Internet access that they are willing to install third party apps on. If I were a resident I would rather have an NFC card or fob I could use instead. It is of course okay if they use a connected app as one authentication method but there should be other ways as well.
    1
  1671.  @robertpatterson5937  The number might be vanishingly small but it includes me. And even among "normal" people phone batteries die or other glitches can occur. As to costs that their system is 20% off what an equivalent L2 charger costs, I call BS. It's easy to find L2 chargers which retail under $200. I even found a $99 one but it might omit required safety features. Unless the Orange system is under $40 per port they aren't being honest. A smart outlet requires GFCI and a contactor just like L2 chargers do. The signalling for L2 charging is super easy to implement. The main difference in cost is the connectors.
    1
  1672. I'd imagine your appliances are a bit different, isn't your power 127 instead of 120 volts? For things with "dumb" motors etc. this could be enough to make a meaningful difference.
    1
  1673. Most modern LED bulbs have an aluminum can under the plastic cover. It's not quite as good at heat transfer but it's cheaper than needing to fully isolate exposed metal and it's certainly better than no heatsink.
    1
  1674.  @harishvora1741  I disagree, it actually could be a nice marketable feature. About 1kW of panels fits on a car and assuming 6 hours of strong sun per day would provide enough energy for the average EV to travel around 19 miles or 30km.
    1
  1675. Both ducted and mini-splits are placed on the same scale. Ducted systems require large circulation fans and thus are always less efficient than an equivalent ductless unit. Also it just isn't a particularly great performing unit.
    1
  1676. EVSEs only use as much power as a house air conditioner. If the grid can handle those during the day they can handle charging a car at night. And there are actually ways for the power company to tell EVSEs to back off, I just don't know how widespread they are. The same is already done with smart thermostats.

  1677.  @noahstuart3025  Hydrogen combustion engines would just put out more water than FCEVs because they consume more hydrogen.

  1680. DC fast charging at apartments would be worse because nobody wants to make an extra trip down to move their car when it's done charging. A larger number of load-sharing level 2 chargers is a more sensible choice. When somebody is sitting already charged it would have no effect on everybody else.
    1
  1681. That's great and they certainly should improve the infrastructure. But I believe these smart thermostat temperature changes can easily be overridden, they're not exactly forcing you not to use air conditioning. I'd say it's a win-win if it enables your electricity rates to be lower while not forcing you away from being cooled.
    1
  1682. To your first line: Exactly. In mild areas you have COPs of around 4. In cold areas the seasonal average is lower. And half the time the COP is below the average.

  1683. I think you might need multiple antennas working together if you want to use multi-stream functionality. Without that you'll be limited to around 450Mbps on 802.11ac / Wo-Fi 5.

  1684. On a desktop the most likely internal USB device would be a Bluetooth adapter if so equipped. On a laptop the webcam is almost always USB. Fingerprint readers and smart card readers (common on business laptops) are usually also USB based. The kernel knows which devices are internal because the system firmware (supposedly) says so.

  1685.  @peacefulexistence_  If you can only use one API then use OGL. Mesa backends like Zink can convert to Vulkan and DX12 if needed. If you can use two then OpenGL and Vulkan. If you're using an off-the-shelf game engine that supports multiple backends then just enable all of them unless you have a good reason not to.

  1686. That happened with my family's new car. On every previous car the dash only lights up when the headlights are on, and the new car also has DRL. Combine the two and it is hard to notice if you accidentally left the lights off.

  1690. I don't think I've run into any issues like that, but I should also note that I mainly use Clonezilla with Windows systems. Perhaps they had problems in older versions that have since been fixed.

  1691. Dave could say UEFI setup utility but that would leave out people who use a non-EFI BIOS. Older computers still work just fine for this.

  1692.  @Scoopta  My HP DL380p G8 server is surprisingly BIOS-only and its successor wasn't introduced until the second half of 2014. Plus there's all the pre-Win8 machines still out there. This reminds me that I should probably upgrade my T400 to Win10, then I could maybe try WSL2 there. It's not the latest but with 8GB of RAM it's far from worthless.
    1
  1693. You're making me feel old. When I first started thinking about building a new PC 4th generation Haswell was the chip to get. I still haven't built a new PC for myself but last year I stumbled upon that "new" setup after somebody was throwing it out, even in my favorite case from back then.

  1694. Something I've thought of writing but haven't gotten around to starting is a disk fragmenter. Existing defrag tools can improve file access performance on HDDs but my program would do the opposite.

  1695. It has been mentioned before but EVs normally charge at night and most power usage is during the day. Even if they don't upgrade the grid (which they should either way) I doubt EVs would break it.

  1696. If you've ever seen a US plug you'll know we never have sleeved pins. Worse is that many plugs, especially older ones, have the pins surprisingly close to the side of the plug.

  1697.  @anthonychallis2472  We can all agree your plugs are safer (as long as you don't step on them). Somehow I've never managed to shock myself with 120v on a plug but when I shocked myself on purpose in a controlled environment it wasn't too bad. I also haven't tried 240vac but I have touched 220vdc by accident and it was much more spicy.

  1698. But which version of the classic style? In Win95 if you had a gazillion entries it would create multiple columns. In Win98 it was only a single column that could scroll vertically.

  1700. But if you're hand calculating everything why bother with a CPU?
    1
  1701. I'm sure part of the ThreadRipper's win over the 386SX is due to compiler optimizations. Since x86 backwards compatibility is a thing I'd like to see a binary built for the 386 run on the TR to get a more useful comparison. Assuming the 386 has Windows (3.1 or later) a Win32 application would be the easiest way to do this.
    1
  1702. Something I've read about HVAC equipment is that most premature failures are due to not properly installing appropriate equipment. Any appliance should have specified minimum clearances and what you describe would be a clear violation.
    1
  1703. Won't you still have all the VM-related entries (like VMware VMCI) under system devices? You'd probably also want to mask those. Also rename some of the chipset devices, as no PC which can run Windows 10 will be using the Intel PIIX4 (82371EB) chipset. Beyond that there are other signs like the CPU having the wrong number of cores, but that's probably not an issue because it's unlikely anyone can memorize the core configuration of every PC out there.
    1
  1704. I haven't seen it in a computer but in a repair video I did see a bimetallic thermostat used for fan speed control in a 1970s amplifier. A simmerstat would be a bad idea because the constant change in fan speed would be annoying.

  1705. I still don't get why Lithium NMC batteries seem to be the standard for EVs instead of lithium ferrophosphate. LFP cells last longer, don't catch fire when abused, and don't require the horrible to produce cobalt.
    1
  1706. I've heard that before but it's not true, at least not here. Natural gas networks work just fine when the power is out. I believe compressors in the pipeline run directly off gas. Anything that requires electricity will have appropriate backups.
    1
  1707.  @EwanMarshall  I think that's just Texas being Texas. Here in the Northeast we are much better prepared for cold events. We had a massive blackout in 2003 and everything gas was fine. It would need to be a different type of event (perhaps earthquake) to result in a gas outage here. Obviously something could happen but if the gas and electric are both gone I'd be more worried about the zombies with guns.
    1
  1708. The problem is small batteries somebody can carry themselves are just that -- small. A 3kW portable battery weighs at least 100lbs/50kg AFAIK and that's only 10% of a short-range EVs battery.

  1709.  @0x6a09  I don't remember all the details, it was over a decade ago. The related news "Binaries move to /usr/bin requiring update intervention" is from 2013-06-03. There might have been an unrelated error compounding the situation but I distinctly remember being unable to open a new terminal window or even login on the console, I needed to use my one window I already had open to fix everything. After thinking about it, that seems about right. I installed the update which moved bash from /bin to /usr/bin. So then everything (like the login shell entry in the passwd file) which was hardcoded to /bin/bash no longer worked. At the same time there was a filesystem update which replaced /bin with a symlink, solving the problem, but this was unable to be installed at the same time. If I had read the news post I would know I needed to remove all the "extra" files from /bin and then perform the updates in a specific order.
    1
  1710.  @0x6a09  Like I said, if I read the news beforehand it wouldn't have been a problem. It gave the impression that it will break if not babysat. Also note I said I almost hosed my install. I was able to recover because I had kept my terminal window open and I was able to access the website through my old Windows 98 laptop. If I didn't have another computer with Internet access it would have been much worse. Also remember there have been various changes to the package manager over time, meaning an existing live CD most likely can't be used as a good recovery environment. I think I ran into that once or twice. Other than that I never had any major issues. I don't know how different modern Arch is but I'm sure of one thing: it's a bleeding edge distro. Every update might break something. Even when nothing breaks updates might mean interface changes which take time to adjust to. With a stable distro I can update and everything will work exactly the same. Major changes will come in the next version of the distro and there's an overlap in support window so I can safely wait until I have time set aside to deal with the changes and any possible problems.
    1
  1711.  @0x6a09  The changes themselves aren't worse but the timing of the changes is. 99.9% of the time nothing breaks but I'd rather that number be closer to 100. With my luck the 0.1% of breakage would happen right when I need to do something important and don't have any time to waste. If it wasn't clear, I don't think there's anything wrong with Arch. It's a good distro and ArchWiki is great. Arch just isn't the best for me, it's better suited to people who are more of a software enthusiast type.

  1712.  @VeronicaExplains  Usually the antennas and connections are present for the LTE modem even if the unit isn't ordered with the WWAN option.

  1717.  @stepannovotny4291  I've never been there but my understanding is their standard light switches are rockers with down==on. A Marshall guitar amp I had the chance to work on was definitely built that way. I occasionally watch UK electricians on YouTube and their breakers are up==on which sometimes causes confusion for homeowners. If there was ever a concern about things falling on the switch then down==off also isn't great. Because then if something falls then you get plummeted into darkness. Apparently in some earthquake-prone regions the standard is a sideways switch so falling items are less likely to flip them.

  1719. 3 is a typical weighted COP. When it's warm out the COP is higher and when it's cold the COP is lower. If it's really cold (like -20F/-28C) a regular heat pump might get a COP of 1.4. A cascade system with two different refrigerants might run one stage with a low-temp refrigerant to bring the -20F/-28C up to 40F/5C, perhaps a COP of 3. Then the second stage brings this 40F up to heating temperature at a COP of 3.5. The resulting COP would be around 2 which is poor but still better than 1.4.

  1720. Do you have source for this? The first gas water heater listed on The Home Depot's website (Rheem XG40T06EC36U1) has a standing pilot. This model isn't permitted in a few parts of California and Utah but is allowed everywhere else.

  1721. Higher quality units like the APC Smart-UPS do an automatic self-test periodically and will start beeping like a smoke alarm if it fails. If it's bad enough they'll beep incessantly. Also in my experience most power outages are quick. Two-second power cuts are extremely common when there's a transient fault (such as a squirrel bridging the lines) and the reclosers self-reset. I also get ones which are just a few minutes, presumably for maintenance. UPSes help here and for home users safe shutdown usually doesn't matter.

  1723.  @OldManBadly  Uhh, no. OBDII is only required to deliver basic powertrain and emissions-related information. Other things like driver assist systems, climate control, etc do not need to go over OBDII. And if you are saying our law mandates a non-standard system you clearly haven't read it. Here's some exact wording lifted from the law: "motor vehicle owners’ and independent repair facilities’ access to vehicle on-board diagnostic systems shall be standardized and not require any authorization by the manufacturer" and "shall be required to equip such vehicles with an inter-operable, standardized and open access platform across all of the manufacturer’s makes and models".
    1
  1724.  @OldManBadly  @Old Man Badly Do you have a source for those going over OBDII? Maybe they changed the rules but when I worked on a MY 2011 car I needed to use proprietary sequences in order to read an HVAC DTC. Also from what I can tell Tesla vehicles do not offer any data over OBDII.

  1727. DIY folks have a better handle on used EV batteries than Tesla. Usually a battery which fails early will only have a couple of bad cells; replacing the just bad cell or even the entire submodule is a much greener approach than replacing the entire battery. For reference a Tesla battery pack seems to be made of 16 modules, each with around 450 individual cells. There's also a thriving market for secondhand EV batteries for use in home energy storage, DIY vehicle conversions, and other projects. Here even substantially degraded cells can live a second life where the demands are not as great. Oh, one more thing. Not every electric car is an expensive Tesla with a gigantic battery. Hopefully as EV adoption continues manufacturers will offer different models with different battery sizes and prices. Why pay for and drag around a heavy 250 mile battery if you only need 100 miles of range?

  1730. It's actually fine to wash (most of) your components. Obviously you can wash case panels, but circuit boards can be washed too. Water and electricity don't mix but water and electronics do. Just make sure that ALL the power is disconnected (including the CR2032), don't wash anything that spins (drives, fans, etc), and let it be absolutely dry before powering back on. Hard water could also cause problems, it's best to rinse with alcohol afterwards. Of course, generally you shouldn't wash your motherboard but if you have an old system which is disgusting it's always an option.

  1732.  @evilgremlin  I imagine either his LED panels have built-in current limiting, or he is using current limiting through his boost converters. Modern LEDs seem to be well matched from the factory, so if all his panels are from the same batch they will probably word fine if dimmed. Maybe it will be uneven at super low brightness, but 10% should be more than enough to eliminate that.

When the car is lighting the road in front of you and the dashboard is lit it's easy not to realize the headlights aren't on. You would need to notice the incorrect beam pattern or you would need to know that there is a dedicated symbol on the dashboard to indicate the headlights. Unless you're specifically thinking about it you probably won't notice.

  1740.  @chaosfenix  I have no idea really. Assuming the soft switch is only lightly loaded it would probably be something like going from .1us to .5us but the downside is it would be less consistent. The more it's loaded the more it will increase and there's also other software tasks to worry about. As well as power-saving modes (if used) will take time to transition.

Since loss of battery power not preceded by low battery is rare the data loss argument doesn't really hold. The problem with hybrid sleep on laptops is that it takes significantly longer to go from pressing to the button to actually sleeping. If you want to put a laptop safely in a bag this is an issue.

  1748.  @nerys71  There's a bit more needed, most importantly defrost controls for evaporator. The most efficient way to do this is by reversing refrigerant flow but in a pinch you could use a resistive heater on the evaporator coil. When the coil ices up you turn off the compressor and run the heater until the ice is melted.

  1749.  @jhoughjr1  Plenty of heat outside. The absolute coldest temperature ever recorded is -128F. On a thermodynamic scale that's 184K, meaning there's still 62% of the heat as temperature of 70F / 294K. During a more reasonable winter there's much more heat.

  1750. SDHC (4-32GB) and SDXC (64-512GB) are apparently exactly the same protocol, the only difference is the required file system. This came much later than the format dialog.

You're relatively unlikely to switch to an older version on a single-user home system but on a network system where your home directory is over NFS it can easily happen.

What if we built a device which could scan the point across the entire room, transmit the point to a remote location, and then reconstruct all the points into an image? It would be like vision at a distance. And then there's this Greek word tele, meaning at a distance. We could call this hypothetical technology "vision-tele" to sound cool.

  1765. IANAL but I believe the Magnuson–Moss Warranty Act makes it so adding an oil catch filter won't invalidate your warranty.

  1784.  @bish0pca  It looks like mDNS forwarding for IPv6 might be a bit problematic. The devices might be using link-local IPv6 addresses which definitely won't work. For it to have any chance of working you'd need a real IPv6 setup. The obvious solution is to have the Home Assistant server (or at least the Matter integration) running on the same VLAN as the devices but this is what you're trying to avoid. The protocol is still super-new but in time I'm sure someone will develop a Matter-specific bridge which would relay the traffic between networks.

On a newer Pi I'd expect Pentium III-like performance at the very most.

  1791. You probably have a flaky connection on something. Unplugging and reconnecting everything in your system should fix it. Assuming you don't want to redo literally everything I'd start by reseating the RAM and verifying the power cables going to the motherboard. You can run your system with the cover off and then wiggle parts until you find the one that freezes it.

  1793. Some of this type of unit use a coolant rather than refrigerant to bring the heat inside (or outside). This requires a few more parts (which could explain some of the price) but keeping all the refrigerant outside has some huge benefits. In addition to easy flex joints it lets them safely use more dangerous refrigerants which are often more efficient.

  1799. With a late Pentium or a Pentium 2/3 it should be pretty easy. Only thing different from a modern system is more jumpers, but by then it's mainly just to set the CPU speed. You just need to know the proper bus speed and multiplier of the CPU, then look at the legend on the motherboard to know which jumpers to set. You'd also need to set the master and slave on IDE drives but that's not hard either, just beware of WD drives which require a special 'Single' setting if used alone.

Unless I'm mistaken any application can set this value on other apps' windows and suddenly this means you can cause taskmgr to jump to any point in its memory space. This probably isn't a huge issue in Task Manager but it could be worse in other programs using a similar technique, especially if they are running with different permissions.

  1809. Videos often don't talk about cost per unit of delivered heat because it depends on utility rates which are different everywhere. I also live in an area where heat pump heating costs more than gas heat but plenty of people have cheaper electricity, more expensive gas, or no gas. I'm also going to point out that common units seem to consistently get a COP of 3 or better whenever it is above freezing outside. Personally I'd most likely go for a "dual fuel" heat pump + gas heat if specifying a new system. On warmer days when the heat pump works better use that, on colder days when heat pump is noticeably more expensive switch to gas. Or if one malfunctions use the other one instead of being left with no heat.

  1810. The newer ECM blowers use ball bearings which should last longer than the sleeve bearings used in most older furnace blower motors. I recently replaced my sleeve bearing blower motor and the wear was very impressive. There were large grooves in the shaft (probably at least 1-2mm deep) and looking closely I could see a taper in the rotor from it rubbing against the stator. I suspect all this wear was from the sheer number of rotations it saw over 27 years, I don't think cycling had much to do with it.

  1814.  @ThoArtOne  I wouldn't say all of them are low quality but it does seem hard to find a good smaller-capacity PSU at retail. Higher-end manufacturers tend to focus on the higher-wattage ones because that's where the money is. If you want a good small-capacity PSU your best bet is probably to pull one from a business-grade PC. The problem is these are usually more like 250w, probably only good for IGP systems.

  1818. Switches in NA should all be like that, as it complies with our electrical codes. The "nice" thing is that electrical code only covers the building wiring, not anything inside appliances. TLDR: if the switch were made to go in the wall, it would need the regular colors as you said.

  1821. In most of the US heat pumps are cheaper year-round. Here in Massachusetts (with expensive electricity) an air-air heat pump is currently cheaper than gas when it's more than 45F outside. Heat pump COP drops a bit in the cold but on modern units the capacity stays up until subzero. The heat pump I've been eyeing (Comfort-Aire VCD36) is rated 39kBtu/h@COP 3.18 when it's 47F and it drops to 32kBtu/h@COP 2 when it's 5F outside. That's not a massive drop. Single-speed R22 systems are much worse.

  1822.  @00000005547  Most server applications rely on random disk access IOPS instead of sequential speed. A single HDD may give 200 MB/sec sequentially but on random access you'll get 100 IOPS on a 7200rpm drive if you're lucky, equating to under 10 MB/sec. The cheapest consumer SSD will give you 10 times this, high end U.2 ones 1000x. Per IOPS SSDs end up being way cheaper than HDDs, not to mention the space and power savings. For reliability, why do you say HDDs always give warning? Sure they do sometimes, but the same can be said of SSDs. SSDs have a very clear wearout indicator which gives you a great idea of drive aging. You'll still have sudden controller failures but HDDs are the same. If you look at a server vendor's website SSDs are in most of the preconfigured options, and not without reason.

  1823. Oddly enough I took apart the same Intermatic model D111 timer after it started acting up. Mine has a polarized plug (and socket) and a white dial but is otherwise identical. I always found it odd that it needed to be plugged in upside down. For completeness sake the motor has many poles so the rotor turns at much less than 3600 rpm.

  1825. 1. In heating mode there's no such thing as waste heat. 2. Laws of physics. You can't turn heat back into electricity. The best you can do is turn a temperature difference into electricity. To generate electricity on your AC's waste heat the coils need to run hotter than normal in order to get this temperature difference. It takes more electricity to do this than you make back with the generator.

  1826.  @mitchhaelann9215  You're talking about harnessing energy wasted by heat conducting out of ducts and going outside? That would work but it would be so much cheaper and easier (and overall more efficient) to improve the insulation and reduce the loss. If you're talking about heat conducting out of ducts and into the living space then once again it's not waste heat.

  1829.  @storms13  Jay suggested it mattered, but I tend to agree with you. It's pretty irrelevant at these levels, hence why I included the word "very" twice. I'm sure the additional heat produced by running fans at full power would make more of an impact on room temperature. I have some fans which draw 20 watts each (by measurement). Granted they're "a bit" too loud for a gaming PC but I imagine 10 watts is fairly normal. Multiplied by the six or more fans some systems have that really starts to add up.

  1837. Older cold climate systems also work, in fact most current models are a few years old. I'm betting your heat pump is not a cold climate one. If it actually is cold-climate then it's undersized without aux heat. If what I've heard about Texan houses is true then you can probably improve your system by improving insulation. If you have uninsulated ducts in an attic then fixing any leaks and adding extra insulation could probably save 20%.

  1840. Do you mean ended when they released the T410? The T400 is the same design as the T60. The T410 (technically the T400s but nobody cares about that model) brought the mildly inferior keyboard, removal of many indicators, moved the UltraBay release, and probably other things I"m forgetting.

  1844. It depends. Many plug-in ones have 14-50P plugs which require a neutral (so 8/3). Most hardwired EVSEs (and all with a 6-50P plug) don't need a neutral and so can use 8/2 cabling. Something else to consider is aluminum wire. I believe 4 AWG is the smallest allowed which can carry more than 50 amps. It's more difficult (and thus expensive) to make proper connections with Al wire but for a longer run the lower wiring cost is likely worth it.

  1845.  @SuperS05  60% is quite low even for a natural draft furnace, AFAIK the average for 50 year old units was already 70%. My late-model natural draft furnace at home is rated 78 AFUE.
    1
  1846.  @SuperS05  The 78% furnace has a (broken) damper in front of the burner intake but I don't see how it helps efficiency when the furnace is in an unheated basement. Runtimes are usually at least 15 minutes even in mild weather so it should be running steady state most of the time. On this note, the efficiency of most dumb systems can be improved by adjusting thermostats for longer runtime.
    1
  1847.  @SuperS05  AFICT this furnace only has the one intake damper and it would stop all the draft airflow through the heat exchanger but not through the flue. I don't know how much good it would do because I have the board set to run the fan for 2.5 minutes which I'd think would capture most of the stored heat.
    1
  1848.  @SuperS05  Lennox G20 series. If we end up replacing it we'd probably get a 2-stage 96 AFUE. Not sure if it's worth spending thousands to prematurely replace it with a unit that will probably die sooner. If the attached AC fails then I'd like to replace that with a heat pump, possibly a non-communicating inverter model. We have rebates for switching to heat pumps but there are very few units that are rebate-eligible when paired with an existing furnace.
    1
  1849.  @SuperS05  How likely is it that the furnace Hx is cracked without me noticing? The flame doesn't flinch when the fan comes on and when I was changing the blower motor last year the bottom of the flame tubes looked bright and not discolored (although I stupidly wasn't looking for cracks at that time). As for the heat pumps, the one I would be most likely to get was branded as the Comfort-Aire MCD36 but I'm not sure who the real manufacturer is. The same unit is sold under different brands (one might have been MOOV-AIR but I might be remembering that name from somewhere else) but I know all the cheap inverter HPs are made by a small handful of companies like Midea, Hisense, Gree, etc.
    1
  1850.  @SuperS05  Thank you for the information. I know Lennox had lots of problematic heat exchangers in the 80s but I don't know if the G20 has that particular problem or not. Is that the issue you're referring to? I heard replacement HXes have a fixed design and mine is a later version (made in 1995). Do you think it's still problematic? I don't remember seeing rivets but again I wasn't looking for them. We have two CO detectors upstairs but it would probably be a good idea to put one near the furnace and WH too. I presume that would at least let us know if it's becoming a safety issue. I'd probably want to wait until the off-season to take a closer look.
    1
  1851.  @SuperS05  I hadn't realized the detector standard was 70ppm, that's crazy. At least we have one with a display so we can know if it reaches 30ppm which should be safe. If it's been cracked for a decade I doubt it's going to get too much worse anytime soon.

  1857.  @TechnologyConnextras  Fridges aren't much steady-state load but on conventional ones the compressor draws around 10x the current on startup. I have the feeling yours is an inverter model which won't do this. The voltage drop isn't an issue for the fridge (it's designed for it) but this startup current can trip inverter overloads.

  1858.  @brunoais  Charge once but it will take a lifetime to charge. Because I was crazy enough to do the calculations, if you could charge at 100 Watts (USB PD max AFAIK) it would take just under 46 years to accumulate 40MWh.

I did a quick search and the original Steam deck power supply is 45 watts. So 90 years to charge assuming no power losses.

  1862. The rest vector isn't FFFFFF00, it's F000FFF0, Dave made a mistake. To answer your actual question, it's not a 32-bit value but rather two 16-bit values: 0xF000:0xFFF0. In real mode the physical address is derived by taking the segment address, multiplying by 16, and adding the offset value. This comes to a physical address of 0xFFFF0 which fits perfectly on the 20-bit address bus of the 8086/8088 and also fits in the larger 24-bit address bus of the 286. What @johnrumm4786 is saying about the A20 line and wrap around addressing is true and informative but doesn't actually answer your question. Also not directly related to your question, even in protected mode the 286 uses 16-bit addresses. The difference is you could redefine the start location of each segment.

  1876. That is not a valid argument for oversizing. A system that's half the size will push out half as much heat but also half as much air. The result is the same supply air temperature. In fact this reduced amount of airflow will make the smaller system feel less drafty. And side note, this is part of why our vents in heating-dominated climates are always in the floor whenever possible.

The only question is how quickly and how much leaves via radiation or via conduction/convection. The only real loss in transfer efficiency is the amount of heat lost via conduction to the underside of the stove. AFAIK it is worse with lower temperatures but with thermal insulation I don't think it's enough to really matter.

  1896. Yes. If the click comes a couple of seconds after you switch it on you are hearing a speaker protection relay.

This stops the speakers from thumping when the amp is turned on but more importantly protects the speakers from excessive current if the circuit malfunctions.

  1897.  @lisdraw4715  Short answer is maybe. There are so many amplifier circuits around it's impossible to know without looking at the details.

  1908. Why was it horrible?

  1909. Most of the issues you are describing will mostly be OS (and to a lesser extend device-based) as AFAIK the main BIOS is only responsible for keeping RAM intact and re-entering the OS. Actually ACPI code (which is stored in the BIOS) is likely responsible for much of your problems as it can potentially tell hardware to cut power to certain components. In any case I don't remember having many problems like you describe so maybe you were just unlucky with your machine models. And of course some things like Bluetooth devices being disconnected are going to be because it's physically impossible for a device to stay connected to an unpowered host. For USB disks being lost, it could also be drives which aren't able to reconnect in a reasonable amount of time. I've encountered that with some devices but usually flash drives work just fine.

  1919. It looks like a 5kbtu air conditioner uses a bit less than 500 watts. Since an average solar panel puts out around 300 watts, you'd only need 2 solar panels. If you also want it to run outside of peak sunlight hours you'd need more panels. Here in Massachusetts 7 or 8 panels would produce enough energy to run all day into the night (assuming you have a battery). If the air conditioner reaches temperature and cycles off you wouldn't need that much power.

I don't know what size cord you use but 12AWG is pretty heavy. Cable insulation is also much stiffer in the freezing cold so whipping an identical cord around will be harder. Not to mention you probably mow when it's nice out but snow blowing often needs to be done around ice and in poor lighting, along with the obvious cold.

  1932. It is annoying with high-temp baseboard heating. The easiest thing you can do is lower the water temp until the radiators don't put out enough heat, that could be easier than a proper load calculation. If needed maybe replace a few of the static radiators with forced-fan models. While not silent they can be pretty quiet. Regarding problem 4, consider a monobloc unit. All the refrigerant stuff is in one box that sits outside. Only a few wires and a pair of pipes go outside, making it fairly DIY-friendly. One nice-looking brand that I've heard is friendly to DIYers is Chiltrix, however their leaving water temperature is lower than other AWHPs. Of course the easy "solution" is mini-splits.

  1940. Over the air DTV is unencrypted. While it's annoying when it doesn't work it's not at all evil other than the complete lack of backwards compatibility. Digital cable is much more sinister because you need to rent a device in order to be able to decode the signals.

  1941.  @c182SkylaneRG  I get about a gazillion channels on DTV these days so that's true for me. For reference the DTV channel numbers the user sees are decoupled from the actual RF channels carrying their signal. So it doesn't matter if something was originally on a low VHF channel 2-6, now it's probably on UHF 14-36. The reality they didn't tell us is ATSC was designed to give good results using a rooftop antenna. Portable antennas (like most TVs were probably using) weren't a priority.

  1957. To start with most people have refrigerators. If you have a kitchen fridge and a second garage fridge that's already close to 200 watts continuous (equivalent). Then there's stuff like cable modem/routers and TV boxes/DVRs which are probably pulling another 50W continuous combined even when not actively in use. Then things like microwave/stove clocks and other stuff drawing at least 20-30W combined in standby. That's almost 300W before you turn anything on.

    1
  1969.  @eformance  At the end of one quarter-cycle the line is -170V and the capacitors are charged to 170VDC, then the line goes to zero and the caps start to discharge. Let's say they discharge to 140VDC in a quarter cycle. Then the modified sine inverter puts out +170V and the caps are forced to charge instantly.
    1
  1970.  @eformance  The capacitor charge rate is based on internal resistance as well as the rate of voltage change. When the voltage changes suddenly the capacitor RMS current can be easily well over twice what you'd see with a sine wave input. If the capacitor is overspecced it will be fine but if not they'll heat up more and fail earlier. For periodic use on a UPS the difference in lifespan will be negligible. But if you are running full-time on an inverter I would expect noticeably more failures over several years.

If the voltage is always high but never low there might be a different transformer voltage tap they can switch to in order to correct the problem.

  1992. Side-discharge outdoor units have multiple rows of coils. They perform the same as a single-row system with thinner coils. Defrosting still is an issue but it's not that bad. Defrosting only needs to put back the energy that was taken to freeze the ice. Since defrosting COP is very high this is negligible energy loss. As long as more energy is extracted from the air than is going to freezing condensate it will maintain efficiency. The bigger issue with defrosting is the momentary loss of heating capacity.
    1
  1993.  @bpark10001  The first row does most of the work but the second and third rows do some, just like how 96% furnaces with an extra heat exchanger transfer more heat than 80% single-exchanger furnaces. Regarding defrosting, all of the energy needed to melt the ice is already transferred inside the house. Assuming an infinite COP when defrosting the overall COP won't be hurt at all, it would just be like you ran the unit in heating mode for less time. In reality the COP is not infinite but a realistic COP of 5 is 80% as good. And you don't need to waste 500x the heat evaporating all the water after melting the ice. If it doesn't drain off naturally then run the fan to force it off. As I said before I think the main problem with defrosting is loss of capacity, not loss of COP.
    1
  1994.  @bpark10001  Yes you lose some COP, I"m not arguing that. My argument is that the loss in capacity (due to lost time) is much more of a disadvantage. I agree that the advantage of having multiple rows of coils is small. But it does help, you need some superheat/subcooling to maintain proper operation and thus the end of the coil doesn't do much. The main advantage is that the fins are thicker, giving more surface area. The cube design works fine, it just takes up tons of space. The smaller footprint of side-discharge units is their main advantage. You have correctly noticed that mini-splits appear to have smaller outdoor coils than conventional units but I think you're missing part of the picture: they're mini systems with smaller capacities. Side-discharge units for 3-ton and larger systems are over 4 feet tall.

  1995. If both furnaces are from the same manufacturer and are in the same size cabinet then the blower will be the same. The smaller one will blow more slowly. With an ECM blower (standard for the past 3-5 years) the power draw is proportional to the cube of the airflow. The electric consumption of the half-output furnace is therefore 1/4 as much. If you have an older PSC motor efficiency drops at low speeds so you don't have this win.

  1999. Why would something with a ton of gasoline-based energy still need an external boost to get going? In an EV all the control circuitry runs from the 12 volt supply. Most important here are the battery contactors which physically disconnect the battery when not in use or if a fault is detected. Unless the contactors have a steady 12 volt supply you don't have a high voltage supply at all.

  2000. Supercapacitors often have a high self-discharge rate which would waste energy, but much more importantly for a given amount of energy storage they are many times larger and more expensive than batteries.

  2001.  @alakani  Energy density is still an issue. According to the Wikipedia page ELDCs have up to 3.9Wh/kg. To store 1kWh you'd need over 250 kilograms. If the density is similar to water that would be something like the internal volume of two minifridges. Definitely not easy to integrate.

  2002.  @alakani  Those numbers don't seem right. I looked up SkelCap (hadn't heard of them before) and their website has tons of links for their latest 3200F model. They specify: 6.7Wh/kg and 8.7Wh/L. This would be 150kg and 115L for 1kWh. 115L is 4ft3 or around 1 19 inch cube. You'd need 278 of these for 1kWh and at probably $50 each (when purchased in bulk) that's almost 14 thousand dollars. I'm surprised that it ends up being that small but it's still a bit too large and way too expensive.

  2003.  @MrAranton  It is like that today. Have you ever heard Louis Rossman complain about not being able to get a CD3217 or whatever chip. Back in the day people who didn't know what to do did have a starting point to try and figure it out for themselves: books and magazines. Regarding suing over charged capacitors: I just looked at two TV service manuals (one from 1948 and one from 2000) and neither mention charged electrolytic capacitors as a shock risk. Companies only get sued for hot coffee when the coffee is served above typical temperatures without such indication. Basically everything already has shock risk warnings because they know lack of a manual won't stop anyone from shocking themselves.

  2018. The cost balance depends on your local utility rates. In Massachusetts with current utility rates, my current furnace, and the heat pump I'm looking at gas is only cheaper when it's below about 30F. A gas-only system costs less to buy and a bit less to run but most homes made here in the past 50 years have central air conditioning. A gas+AC system isn't much cheaper* to buy than a gas+HP system. If you opt for a new heat pump instead of a new cooling-only unit you'll probably have ROI within a couple of years just from the shoulder months. Even if the furnace were always cheaper the HP can be used as a backup. *I'm talking about cost before incentives. Our rebates more than cover the cost difference between HP and cool-only, making it a no-brainer.

  2019.  @lizelleswanepoel116  Insulation costs are irrelevant because all heating systems benefit from better insulation. If you don't want to insulate you can just use a larger heat pump. In terms of noise, they're no noisier than regular air conditioners.

I suggest watching Rich Rebuild's rat rod project where an electric motorcycle motor is mated to a 3-speed manual.

  2041. People have thought of that and there are real problems but it's not as bad as you suggest. California's existing infrastructure can handle the load, just not at once. During their most recent crisis they were asking customers to charge their EVs at night when the grid is much less loaded. Lithium iron phosphate batteries don't use cobalt, are much less prone to "incidents" and last longer than regular lithium-ion batteries. They are a bit less energy dense but I think the tradeoff is well worth it. There is a thriving market for used EV batteries for reuse in less demanding applications. By the time they are totally used up the materials demand should make recycling more common. The question is whether or not this is better than mass burning of fossil fuels in vehicles.

  2047.  @christo930  On a technical level the only difference between an AC only unit and a reversible heat pump is the addition of one extra valve, so the manufacturing price difference is minimal. Because it's such a simple difference they can fit in the exact same locations. While EVs increase demand for electricity it's surprisingly little compared to total grid usage. If EVs are too much for a grid then the grid is already too close for comfort. With home solar growing faster than EV adoption power generation is not going to be the limit.

  2108. ​ @whitslack  You can use multicinductor cables inside of conduit but there's one big reason this isn't done. Loose wires are more flexible and easier to pull, especially if it's made of stranded conductors. Loose wires are also functionally more flexible as you can pull exactly the combination of wire you need on whatever color you want. And it's a bit cheaper than multi-conductor cables. The main reason you can't use loose wires outside of conduit is that they don't have the protective sheath. Some single-conductor wires do have sufficient protection but then you run into rules where AC wires need to be kept together. You will likely only find individual wires used outside of conduit in a string-style solar setup, or possibly in a battery bank.

  2111. Gauge-based systems made sense back in the day. The number was originally based on the number of times the wire would be stretched through a die in manufacturing. The higher the number, the more times it's stretched thin. While it's annoying it does make sense given the history. Well, except for the multiple zeroes. Negative numbers would be most logical.

  2114.  @MrMadsci7  With a high enough COP electric heat will be more efficient. For my utility rates the needed COP is about 5. The most efficient mini-splits reach this when it's only slightly cold outside. When you add solar panels the electric cost per kWh is slashed, making heat pumps more approachable.
    1
  2115. I'm guessing you've only used old-school single (or dual) capacity units. Most well-integrated inverter units stop (or almost stop) the blower so you're not blasted with cold air.
    1
  2116.  @jfess1911  Both approaches work. Stopping the fan is great when there is excess capacity, running aux heat full blast is better if you're close to running out of capacity.
    1
  2117.  @jfess1911  Short version no. They don't have a way to send warm air to the AHU coils without either blowing cold air or using aux heat. They try to rely on the heat that's already in the indoor coil. If they need more heat they'll move just a tiny bit of air, small enough that you won't feel a cold breeze. At least this is how mini-splits (which usually don't have aux heat) do it. Central ducted systems are probably more likely to blast their way through with lots of aux heat. It should be easy for them to modulate the aux heat during defrost but I have no idea if they do this or not.
    1
  2118.  @jfess1911  I'm curious how your system was wired. Is it using a conventional 24v thermostat or a communicating one? With a conventional thermostat I would only have the full aux heat on if the thermostat is calling for aux heat. If the heat pump but not the thermostat is calling for aux heat then have it only use the smaller heat strips regardless of the outdoor temperature.

  2119.  @traindad77  That's not true. The government only allows explosive refrigerants in small systems where there's minimal danger even in the worst possible situation. IMO flammable refrigerants should be used more because AFAIK they work well, are nontoxic, and have minimal environmental impact compared to complex modern refrigerants. And btw R600a is isobutane. Propane is R290.

  2120.  @gags730  A Whirlpool dryer with lint filter on the top is the most reliable ever made? That's what my parents bought new 30+ years ago and it hasn't needed any repairs even though we've been neglectful in maintenance.
    1
  2121.  @gags730  That's a bit much for me to remember. In terms of maintenance I've twice cleared out some dust from the bottom of the unit and once I think I added a drop of oil to the motor. I guess this is what you're calling a "really old" model because the bottom front panel pulls off without any tools. If it ever gets a no heat problem and the igniter doesn't glow I'd probably just check for 120v on the connector towards the front. All the symptoms you describe line up with my understanding of the circuit. It's only three components so there's not much that can go wrong. My favorite part of the circuit (as I understand it) is the end of cycle buzzer. If the centrifugal switch is engaged but the main feed for the motor is not active it sounds. Pretty elegant IMO.
    1
  2122. Not really. A system 1/2 the size uses about 1/2 as much power which cancels out the increased runtime. With forced air systems the blower power is proportional to the cube of the airflow, so when you push a given amount of air at half the speed it uses 1/4 as much energy.

  2141. Version number parsing is useless for most purposes as user agent strings aren't standardized and different users may have different features enabled or disabled depending on their installation.

  2142. Yes. I think it actually worked pretty well for me (but then again I didn't use it much.) IIRC I could use it for text but video was unusable. I actually have two DisplayLink adapters nearby, one is part of a USB 2.0 "dock."

  2143.  @jeffgayzose8129  I don't think it's that much more difficult. They would probably use multiple smaller packs instead of one giant one. This would afford designers more flexibility as well as make replacement more manageable.

  2144.  @jeffgayzose8129  Batteries and electric motors will never be 3x more efficient because they're already well over 75% efficient in practice. The only issue is energy density of the batteries. I don't think making the batteries removable would take up much more space. No matter what the battery needs its own (fairly) protective shell and the chassis needs provisions to hold it. To make it removable you just need to make the holder accessible without taking the machine apart. It doesn't need to be as easy to change as a power tool battery. I'm envisioning something more like how the starter battery in an ICE vehicle is held, something that may take a few minutes and even require basic tools.

  2145. I believe each USB controller can handle up to 127 devices, so number of devices most likely will not be a bottleneck. If you want to have 1440p at 144Hz, I think most adapters supporting 4k@60Hz will work. Both modes use about the same bandwidth. This probably means DisplayPort 1.3.

  2146.  @Kalvinjj  And also CRTs themselves (at least monochrome ones) are actually fairly low power. Most of the power usage is from inefficiencies in the deflection and other circuits. A standard 1940s CRT only uses four watts at the neck and if the picture's bright maybe a watt or two for the beam. More modern ones use even less power at the neck.
    1
  2147.  @Kalvinjj  It is like saying LCDs use little power but the backlight does. When they switched from CCFLs to LEDs monitor power consumption dropped dramatically. With modern circuitry optimized for low power they could make CRT displays which use less power. One easy way to save power is to use electrostatic deflection instead of magnetic. The downside is electrostatic CRTs can't have large deflection angles, so they'd be uncomfortably deep for large screens.

  2155.  @michaelsexton1107  If there's sufficient coupling of the generator's waste heat into the heat pump it will be a more efficient use of energy than a furnace. The question would come down to how much coupling is needed and whether or not that much coupling is feasible. Putting the generator and heat pump outside unit in a sealed box would provide good coupling but this isn't an option because the generator needs fresh air intake and exhaust. Adding tubes for intake and exhaust would be feasible but might not meet safety standards, plus you'd need to make sure you don't overheat anything.

  2157. Back in the day my elementary school had an even simpler demonstration of energy-efficient lighting. They had a volunteer come up. They asked him to put his hand on the CFL. Next, they asked him to put his hand on the incandescent lamp. Naturally they didn't actually let him do that but it still gets the point across. The main disadvantage of this versus the radiometer setup is that somebody needs to come up and feel what's happening, they can't just see from a distance.

  2159. The battery definitely won't handle all-day cooking but the battery oven also has a standard wall plug. The 1800w available from the plug is probably sufficient to offset the heat lost through the oven walls, meaning the battery is only needed when preheating or if you open the door too long and let all the hot air out.

  2161. I actually have seen an old battery-powered flip clock at a yard sale before, but as it appeared broken I did not buy it. I regret that mistake. Regarding flip clocks not flipping the minutes card very consistently, couldn't they just use a mechanism similar to the extra catch on the hours cards? The extra minutes catch would then be activated by the seconds "hand". And one last thing, a good aspect of my rolling-digits clock (similar to your stock footage but with a continuously spinning seconds wheel) is that the alarm time is exactly as you set it because it is tied to the intermittent movement of the tens of minutes wheel. I consider myself an amateur electric horologist myself, btw.

You can also run multiple applications over a single connection. I don't know if the underlying protocol requires a dummy framebuffer or not (it might be an implementation detail) and from a user standpoint it doesn't matter. VNC is definitely a dumb framebuffer and is no fun. For X applications Xpra works pretty well. I imagine it's possible to add support for Wayland applications. If nothing else, a "reverse xwayland" could be used as a shim.

  2167. I disagree. You only get a pass if it's useful energy usage. I was going to put in my spare 48 port switch to connect a few things but I just learned it pulls 75 watts at idle.

A cheap alternative could be made by capturing a picture of a window right before hiding it. This would be uniquely easy with a tiling window manager because then there's no such thing as an occluded part of the window. As for the actual amount of support needed, I don't know. All the native GUI coding I've ever done is for Windows.
