Youtube hearted comments of Mikko Rantalainen (@MikkoRantalainen).

  1. I was aware of the change blindness / selective attention (the original test with gorilla) so I did notice the tail fin. However, trying to be aware of the surroundings caused me to be off-by-one for the juggling so I failed the main task by trying to be aware of the surroundings. It's easy to imagine that under stress you would need focus on the main task so much that you would fail to notice anything abnormal nearby.

  2. It's interesting that Asiana had company policy to use autopilot at all times possible but still the training didn't result in full understanding of the various autopilot modes. I would have assumed that with such a heavy emphasis on autopilot, fully understanding the autopilot behavior in all modes would be critical.

  3. Git with merge workflow is easy to explain to anybody. The hard part is to help non-technical colleagues to select a plain text editor that's actually good. And no, Notepad or Word are not reasonable options for writing plain text files. That said, I think rebase workflow is clearly superior to merge workflow if your team can handle it.

  4. Great research results! Maybe the same method could be used to avoid clogging in flow batteries, too?

  5. Really nice car and I definitely liked the "seriously used" looks. Much more interesting than the polished paint jobs this kind of cars usually have. With improved suspension it will be great!

  6. 13:23 The approach to foxhole looks insane with this dim lights! Hopefully you could see more while driving the car.

  7. 4:25 Great to see an actual torsion wrench being used to change the wheels. Way too many shops just use impact gun at high power.

  8. 16:10 "Okay. Andrew started out trying to build an audio workstation and ended up building a language that also includes a C compiler." This kind of reminds me of RMS trying to fix the situation with closed source printer drivers and ended up building a whole open source operating system (with help of other people such as Linus). And in case of GNU/Linux, many printers still do not work.

  9. 23:11 "and you probably save more money saving your tires than saving a tiny bit of fuel" I fully agree you there! Tires are so expensive that having extra tire wear is not worth only a slight improvement in the fuel economy.
    13
  10. Good to see you back. I was already worried about you when I didn't see new video last week.
    13
  11. Awesome video, as usual! In the end, I can only wonder how on earth this airport was allowed to operate this way? It clearly had lots of things wrong and still was used for commerial flights. I would understand this kind of problems for hobby use and IFR conditions.
    11
  12. 15:50 How on earth tower control or ground control wouldn't be aware of all markings on the taxi roads and runway? Is this assumed to be normal today on other airports?

  13. I think that not having clear acceptance criteria is the most common problem in the software industry as a whole. With small enough changes (small incremental features) and clear acceptance criteria that's understandable to the team or the sole developer, there's no need for SCRUM or any other complex system.

  14. Right, I actually wrote the same thing and then deleted the comment when Derek said it immediately after I had written the comment.

  15. Great video! I think in short term OpenAI will have success but in long term the near-open source style by Meta is going to win.
    6
  16. I agree. Typically a second hand OEM sensor from scrapyard is better than new no-name replacement part. Especially for parts such as ultrasound sensors that have no wear parts.

  17. I would have never thought that you can make an interesting video about a gas cans, but did great job nonetheless!

  18. Great two first laps. I'm looking forward for a lap with paddle shifters.

  19. I mostly agree with your list. I guess it depends on company but being "Strategic Coder" as you described here may not work for a smaller companies – there might not be enough architecture to focus solely architect job and in that case, a great software architect would navigate the problem space and choose sensible tasks to speed up the development. However, you have to be careful to not lock yourself into too big projects so that you have enough time for the architecture work as needed. And I would have included hardware costs to the cost sensitive part of the video. If you write code in managed languages, the runtime performance will be lower and depending on the user count and who pays for the hardware and electricity, sometimes you should go with higher performance language such as C, C++ or Rust to reduce runtime hardware costs. If you're creating a mobile app and end users are paying for the hardware (e.g. their own smartphones), then you can have more focus in getting things out fast. If you're running AI systems on your own systems for a big amount of users, then you need all the optimization you can get because computational efforts are insane no matter which language you use. Or one could argue that most of this actually belongs to understanding tradeoffs. I think it's the single most important bit on your list.

  20. Good video, again! The only question I have about OFDM is why isn't it made mandatory already?

  21. If extra distance for energy management can avoid even one go-around per 10 landings, it will also save fuel because extra distance is very cheap compared to fuel consumption of a go-around.

  22. It seems that the only part that would have needed a slower cut speed was the camera lens. Everything else seems to cut very nicely even with this cutting speed. That's very nice water jet indeed.

  23. Great results for 2.0 liter gasoline engine! I was expecting much worse results.

  24. Great driving and the car is awesome. It was at times hard to notice that the 5th gear was missing because the gearing was tight enough. Imagine if the original Golf GTI would have been this car without a splitter and the spoiler!

  25. 50:55 Loved the destruction mode! (Great subtitles here.)

  26. 41:20 Great slow motion shots!

  27. Small correction to video: both copper and aluminium fail to work on induction stoves. You want something that reacts to magnets and the stronger a magnet sticks to your cookware, the better it will work with the induction stove. Stainless steel and cast iron are the best. I prefer stainless steel for most purposes because you can throw the cookware to dishwasher and it will take care of itself. Cast iron frying pan is still the best for cooking but real pain to keep clean if it gets dirty.

  28. Loved the field strip in the end!

  29. 2:00 The couging work here is true magic! If welding stuff is metal counterpart of hot clue gun, then couging with this level of skill is similar to using glue removal tools.

  30. Great info about HANS devices. I wasn't aware that any product would have been classified for standard/basic 3 point harness in normal cars.
    2
  31. 12:10 If the car has ESP, make sure you don't accidentally rotate the wheel rotation sensor 360 degrees in either direction (that black thing with two plastic poles). Doing that will cause spring coil like wiring to fail sooner or later. Edit: I see you taped it at 14:10
    2
  32. GR86 was going very nicely around the track. Once you get improved brakes, the limiting factor is lack of engine power.
    2
  33. Nice safety gear... sandals and wiring hold with duct tape!
    2
  34. As an owner of VAG car, I'm fully aware that scan tool can do nothing without the key in ignition so I wouldn't have even bothered to scan the car when the ignition key doesn't seem to react at all. Great work otherwise and you had some good tips (such as figuring out if the car is trying to talk to the module or the module is trying to talk to the car).

  35. 17:42 Nice, the crane basically had brakes that only worked thanks to rust!

  36. 51:33 If Kurtis ever gets tired of metal working, he could apply for Linus Tech Tips host position... already dropping stuff like a pro.

  37. 26:30 Great to see this kind of improvements to the original design!

  38. This is closest to SpaceX in the Europe!

  39.  @MrAntice  And any code that interfaces with 3rd party code should contain links in comments to the documentation of the 3rd party code that the implementation depends on.
    2
  40. 2:26 I think the US style length "limit" makes zero sense because the combined length of trailer and truck can be literally anything. If you're going to limit the length at all, the European style limit is the only sensible option. I think the European length limit is a bit on the short side, though. Something like 20-22 m max length might be a good option.
    2
  41. How about making similar episode for Air France Flight 447?

  42. Not all induction stoves whine. It's called coil whine and it's caused by coils vibrating in the in magnetic field. Some manufacturers do the extra work required to stabilize the coils to avoid the audible noise. And amount of coil whine depends on your individual unit. If manufacturer doesn't consider coil whine for the QA, units from that manufacturer may or may not have audible coil whine depending on your luck.

  43. Awesome shirt!

  44. Useful product is a very interesting requirement because you can make a product that's highly usable for one specific purpose and really unusable for anything else. Supercars would be one example of this. On the other hand, Swiss army knife is a great example of a tool that's pretty usable for nearly everything but not perfectly usable for anything. I think Earth is too small to have enough storage space to have perfectly customized one purpose tools for everything so we should have more tools that are good enough for a lots of purposes.

  45. Awesome production quality in this video. The only thing I would prefer different is the camera run from 0:07 to 0:16 in the intro where the camera movement seems to lack any kind of inertia (of course, being a simulated video, this is easily possible) and the resulting video looks weird. Other than that, this video has better production quality than most TV shows. Maybe add some acoustic panels to the room you use for the spoken parts to reduce echo, too. That's more like personal preference, the echo makes it sound more like a normal room but makes the speech slightly harder to understand.
    2
  46. 22:00 It still seems plausible that the actual mechanical part of the turbo comes from the same factory but the servo controller is definitely different!
    2
  47. Superb video! I thought that the 3D visualisation of the events were great in older videos but this video just raised the bar a lot! Kudos to whoever did the 3D graphics and livery.
    2
  48. 15:40 I think some modern cars have variable compressor and can have different pressure delta for different requested indoor temperature. It would have been interesting to see if adjusting the cabin temperature would have affected the pressure delta while the AC was constantly on.

  49. It seems that if you don't mind the lube in the cross top, putting the stems and springs in a bag with a lube and shaking a bit would be enough. That would definitely get lube to all the moving parts and you could skip the brush work 100%.

  50. I hope you do a video about new overhead crane installation!

  51. I guess this might be good enough to get the engine running again if you never stress it again. Will it last? Definitely not. Seems like a huge waste of effort to make a subpar "repair". Unfortunately, you cannot repair cast iron parts that require lots of strength because heat expansion will always cause micro-cracking. Look at the thickness of the steel part that originally failed for being too weak already! A 4 mm thick steel plate is not a proper replacement for that. That's strong enough to not break with human forces but it will not last the forces needed to run a truck while running full boost.

  52. Lots of great info in this video. Now I know that stacking dimes is perfectly okay with 6010 but not elsewhere.

  53. 9:30 VAG car has a broken microswitch, news at eleven. VAG cars have nearly always at least one broken microswitch in one of the locks in the car and you have to replace the whole damn lock to fix the switch. Obviously, they also designed the car so stupidly that you have to tear down the whole door to replace the lock. In theory it's possible to replace just the $0.10 microswitch but it's buried inside the lock mechanism which requires tearing down the door and the lock. Basically you have to spend 3 hours to replace that switch. Multiply by the amount of doors with the problem! It's well known that microswitches have limited lifespan in cars. How about making all microswitches easily replaceable, VAG?

  54. 9:05 Passanger/owner of the car is breathing heavily and regretting not wearing a g-suit and meanwhile Misha is playing a secretary and asking if he wants to take the incoming phone call while driving the damn car. That's what I would call Experience.

  55. Great storytelling! You couldn't have even scripted the fuel leak from the corner seam because it was that unexpected.
    1
  56. 13:30 ... Or tell the customer that it costs 850 EUR to fix but use the knowledge and repair kit to do it for 40.57 EUR. Profit!

  57. OBDeleven cannot support iOS (iPhone or iPad) because iOS does not allow 3rd parties to use bluetooth radio. The only workaround is to use custom browser frontend on WIFI AP (which requires that the thing with the OBDII connector includes WIFI access point). This limitation is caused purely by Apple. Android allows free access to 3rd party bluetooth devices and can supports devices such as OBDeleven easily.

  58. Great video! Too bad that you cannot simply replace the $7 spring but need tens of hours of work to do that. And need to replace lots of single-use bolts and gaskets.

  59. It seems that the glitter was way too heavy to stay airborne within the balloon. I guess you would get much better results by small explosion (e.g. small fireworks load) within a cup of glitter inside the balloon immediately before popping the balloon. Another option would be to try to create a fast moving vortex near the balloon inner surface but I guess that's next to impossible to do with a human inside the balloon. If the vortex was moving fast enough, it could keep glitter particles airborne. Third option that comes to mind is small pipe pushing air inside with very high velocity and trying to point the nozzle to the location where glitter drops. That should be able to make the glitter airborne again after falling to ground.

  60. Great video! You just got a new subscriber.

  61. 2:55 WOW! I thought VAG TDI engines with lots of EGR activity and sulfide rich Diesel fuel had bad build-up but this looks even worse. The "after" image around 14:00 looks quite a bit different indeed.
    1
  62. 46:17 If you add a small ramp to the end of the locks, you should be able to slam the door shut without holding the locks open with your hands.

  63. Great news! Looking forward for your future adventures. Are you going to release videos on each of your channels or are the official race videos going to be somewhere else?

  64. I'd recommend doing VCDS autoscan in the background while you're doing other stuff to the car. That gets you fault codes for all parts and also collects all currently used coding so you get almost complete backup as a side-effect. That 4WD issue would have probably shown up in the fault codes.
    1
  65. 5:00 You should have mentioned where the carbon comes from. It's from EGR valve that circulates exhaust gas to the intake manifold. Without EGR the only thing moving in the intake manifold would be fresh air from the air filter and that wouldn't cause any carbon build-up, obviously. The EGR system is there to reduce nitrous oxide pollution and if you were to disable that system, the engine would last much longer but the pollution would increase, hence that's not allowed. However, with the TSI engine design, I fail to understand how EGR system could work even in best case in long term. Is this engine type going to suffer from carbon build-up failures in all cases? The interesting part is could you avoid this build-up if you used the revive product during e.g. every oil change. It doesn't seem to remove all build-up but does seem to have some effect and if you were to prevent the huge build-up in the first place, the build-up will grow slower because the air will flow more smoothly. After there's quite some build-up, it will clog even further pretty fast because of high turbulence due build-up in the intake.

  66. I was hoping to see one collab video with Jimmer where you take the Praga around the ring but this is way better. I still hope to see Praga going on the ring...

  67. The real elephant in the room is that Rosstech (manufacturer of VCDS) has to reverse engineer all this computer stuff because VAG doesn't want to tell about these and you're supposed to use the official (crappier) VAG tools only and those are for official shops only. I wish VAG published the data so that we could have real open source implementations and it would be much cheaper for Rosstech and OBDeleven to create these tools. Right now, the requirement to reverse engineer everything sets a really high bar for anybody new trying to enter the market and as a result, we have less competition which results to worse tools than possible. And more expensive, too.

  68. It would be interesting to see if you could make the ECU happy with the aftermarket turbo simply by adding a variable resistor between +5V and signal wire and adjust the resistor to have 0.5V at the lowest controller arm position. Obviously that wouldn't make the part equivalent to real OEM part but it might have been enough to allow the ECU to accept it and run it correctly! Another option would be to build voltage divider between 0V and 5V wires with pretty high resistance resistors to set the voltage but with high enough resistance the controller arm movement would be hopefully tracked correctly above 0.5V level.

  69. That was smooth driving! I think you should consider getting him into your N24 team.

  70. I would say that when crash damage is fully fixed like in this car, the crash will not reduce the value of the car. The value will go down when you never fix the parts that do not show from the surface. With details shown in this video, it was clear that this fix was about fixing everything that got damaged.

  71. This kind of compilation video also nicely demonstrates how much your production quality has improved over years: graphics are now better and your mic setup is even better. And the baseline many years ago was already pretty high!
    1
  72. 21:40 Video production tip: when you have situation where camera angle is perfectly the same but time has passed in between and the content of the image has changed, do a quick fade to black and back. Straight cut looks pretty weird here when you instantly swap places. Of course, you could also do instant swap and make if funny: for example, Star Trek style teleportation sound combined with straight cut would work, too. And even better with some cheesy sparkles effect on top.

  73. Cleaver idea to use crane with straps to move the bins around. I was thinking you would use chain and need some kind of hooks but your idea was much better.

  74. 16:20 Homey is going to need life-time supply of those crocodiles because he loves them so much!

  75. There was a small mistake in the video. Around 8:05 you show that Fuse 14 is the brownish fuse 4 locations from the bottom but around 9:30 you're testing light blue fuse as "fuse 14". Other than that, great work! I would have expected the wire to be damaged near the connector, not at the "straight" portion of the wire.
    1
  76.  @Diagnosedan  Yeah, I noticed it after getting that far.
    1
  77. 9:20 I would have expected ECU pin for the turbo signal to be bent or broken.
    1
  78. Did you fix the mechanical locks to match the key? I fully understand the key fob not working with the car without replacing the broken module but the mechanical key should match the doors because the mechanical locks must work even if your battery is dead.

  79. 36:00 I think you should weld the word "subscribe" in this tool.

  80. 11:38 That's pure gold!

  81. From the initial description, I would have guessed no fuel getting to engine and cause as something electrical because it started without warning. Didn't expect to see the chain in multiple parts.
    1
  82. 21:10 Unless the subframe bolts are rusted, losening subframe bolts is definitely the best option because you don't even need to remove those to get enough space. And to restore things after re-attaching the bolt you just tighten all bolts again.
    1
  83. 7:45 It seems your camera lens has a bit of oil on the lens surface which causes the blue haze. Check the lens specs if you can use ethanol or isopropanol to clean the lens surface.

  84. Great pedagogy in this video! I think telling the student to imagine bending her toe upwards or downwards to do minor corrections to pedal movement will help accurate controls even more. If you do coarse pedal movement by moving the whole foot and minor adjustments with toes, the overall control will be more accurate.

  85. 11:02 Superb video transition!
