Hearted Youtube comments on Asianometry (@Asianometry) channel.

  1. I'm so glad Vietnam is now united and the fastest developing country in Asia. They really deserve an economic miracle like Korea, after everything they've been through.

  2. Great video! I taught a course on Advanced Packaging a number of years ago and it's nice to see the industry moving towards MCM/Chiplet designs and, now, stacking of chips. Perhaps a future video can be done on passive vs active interposers?

  3. Great video! Love from r/TSMC ❤️

  4. Another issue is that Moore’s Law only applies to microchips. Some politicians act as if similar advances apply to solar cells or batteries.
    145
  5. As someone who works in the industry. You do a fantastic job 👏🏼

  7. This was an excellent (and impressively nuanced) overview of the Soviet economy. I was very impressed. Please make that video about Chinese views of the USSR.

  8. This is an outstanding presentation on CVD diamond. One of the first applications for large CVD diamonds, not mentioned in this video, was the manufacture of windows for aerospace applications, Diamond is transparent to light from infrared to ultraviolet wavelengths, and can be used as a protective, optical window for sensors on the front of missiles or aircraft that is the only suitable material able to withstand impact from rain at high speed.

  9. The reason that he can't do any cigar butt strategy anymore is that his company is so large. By the very definition of a downtrodden firm, it would be so small as to not be meaningful to Buffett's huge balance sheet. He basically can only work with billion / trillion dollar firms as investments because all the small fries on the market wouldn't be meaningful to the whole return, even if their individual return was very good. Edit: Typed this before watching whole video - glad to see it covered.

  10. Faith in the YouTube algo restored, brilliant channel.

  11. Still constantly impressed at the speed with which you manage to put out these high-quality, well-researched mini-docs.

  12. I had no idea about imec until this, and turns out they’re one of the most important organizations for modern technology.

  13. Very fitting video to watch as I eat lunch in Ikea!

  14. I'm forever fascinated by the 'hidden hand' of government in cutting edge technology as evidenced by the DARPA spending on integrated circuits. Maybe an intriguing subject for a future Asianometry video?

  15. I also fantasize about open-source projects for CPUs, GPUs, FPGAs, and a few ASICs with at least one project in each category having a humongous contributor base so that people get good hardware without any IP fee (only manufacturing cost). There will be huge libraries so that anybody can make a custom chip for their application or simply pick the leading FPGA to program it to their needs. There are some big open-source projects like Linux and applications for Linux, ROS, OpenCV, some CAD software, etc. And Linux made Microsoft afraid when they were dependent on selling windows to earn money.
    139
  16. As someone with little to no idea on how chips are made (it always seemed like magic to me) these videos have been quite informative, even for someone like me. I love them, keep up the good work!

  17. Again, stunning presentation and deep insight into difficulties from a technical aspect as well as commercialization. With a lot of the tech websites seeming to be circling the drain, its great to see in-depth analysis is not dead. I fully expect you to reach 1M subs and more in the coming year or two if you can keep this up. I'd rather see 1 every 2 weeks if it would help to prevent burnout. Would be interesting sometime to see an episode on what you think is a potential new technology that is possible in the near term.

  18. As a US Vietnam vet I appreciate this update on the history of Vietnam. I'm glad that after years of colonial domination Vietnam is doing well.
    137
  19. What do transistors and professional athletes have in common? They both get their strengths from doping
    135
  20. It would be interesting if you look into the status of the Chinese in Southeast Asia. In Indonesia, their culture was suppressed and forcefully assimilated during the years of the military dictatorship. I know some hardline conservatives who still see the Chinese as foreigners, despite being a part of the community for generations.

  21. The complicity of analog design is worse when you include temperature sensitivities in the transistor and material performance. My old company (name withheld) included a Power On Rest circuit that gated power to internal logic so that it always started up in a known state. The circuit was updated in a routine design revision that passed all qualification tests across temperature and worked great in industrial grade applications, but came to a screaching halt when it was sold as an automotive product. Process variation of some lots allowed the temperature response of the POR to shift, locking the chip up when you turned it on in a narrow temperature window, A minor issue for a cell phone, but pretty painful if you are trying to unload VW's from a ship in the winter (the ECU wouldn't function). As you noted, analog design is an art, one where you have to know how all the paints mix and interact. Nice job on the presentation, I hope your father was able to retire happily.

  22. Grandpa in the 442nd: My Grandfather and several great-uncles served in the 442nd. My grandfather as a Corporal (w/ purple heart, bronze star) and eventually an MP, maybe attached to the artillery batillion- its not clear.) ...After going through the craziness of the Itialian campaign, France, etc, he saw DACHAU during its liberation. (can you imagine that? With his own family spending most of the war in 'camp', in places like Idaho?) He ended up guarding German POWs, at a former concentration/death camp (not sure which: he was a shutterbug, but the pics I have don't show exactly where, though I suspect it was Dachau, which was used for that purpose)... He was a guard, whole they were sorted into different classifications- draftees, officers, SS, war criminals, etc. Apperantly, He got along fairly well with a few of the POWS, and, as most were cleared of any war crimes, I think he may have identified with some of them as in: 'Well, ain't this FUBAR?', etc. (I'm paraphrasing). Anyway, when my mother was a teenager in the 60s, My grandfather owned a wholesale nursery (for trees/plants), and one afternoon, a stranger came to the door, asking for my grandfather by name. The visitor was a former German officer that was in town to sell machine tools (of course he was- what could be more German?), and had recalled that my grandfather, as a guard, had mentioned that he lived there. The German had brought a six-pack of German beer, and appearently they sat on the porch for a while and caught up, and then never saw one another again. It's a great story... according to my mother and uncle, it's true. My grandfather would never speak about his time in Europe (which is common, appearently), but, I suppose that those were significant moments in his life and for that German ex-soldier. So, wow, eh? I've been thinking about writing a history of the 442, using his life and experiences to personalize/ anchor the history. Anyway, that's my connection to the 442nd. (I have some relics- a camera he 'bought' in Italy, an alabaster statuette, some photo albums (Most of which have been donated to an Asian-American museum- the Wing Luke- in Seattle) -B (One more thing- as a shutterbug, he had a ton of photos of his friends in itally- short-ish Japanese men sitting/ dancing/ flirting with lots of tall, beautiful (recently liberated?) Itialian women. He DID talk about that, a few times... Grandpa was pretty cool.)

  23. Mirror, mirror in the machine, which of you is perfect and clean?
    133
  24. Your broad topic range is definitely my favorite part about this channel. From the economics of countries to genetic cloning to the hearing aid. Great work.
    132
  25. Veritasium made a video about the shadeballs a couple of years ago. Including interviews with one of the engineers who designed the shadeball. It was very interesting.

  26. This is so cool! The first application I thought of was for one of my other interests: astronomy. The issue that large, ground-based telescopes face is that the atmosphere "smudges" the image they create with every bit of turbulence in the air. Nowadays the big fancy observatories get around this by using "adaptive optics", which are optical surfaces that can change shape thousands of times per second to perfectly counteract the distortion caused by turbulence. The whole system uses machine vision, and the calculations have to be done super fast (again, at least thousands of times per second), so (I think) it takes dedicated hardware to do it. But that's out of the price range for a lot of observatory projects. I remember reading a research paper that looked at consumer grade GPUs vs FPGAs to tackle the problem in a cheaper way, and I think they ended up performing kind of similarly. But making a cheap(er) ASIC for that exact task would be incredible! Who knows if that's still how the research stands, that was a few years ago that I read that paper, and I don't know when it was published. So it could be that modern GPUs are so performant that they are the best option. Who knows, but that's just what I thought of.

  27. The Cambridge Museum of Technology has a exhibition on the history of Cambridge Instruments, including an early SEM

  28. I've noticed that people who get really hung up on small, inconsequential details like VLSI tend to have severe emotional regulation issues. You're fine. Hope that guy gets some therapy. Maybe he can make a living doing research for YouTube channels.

  29. I need to wrap my head in duct tape to keep it from exploding.

  30. I remember taking the bus from Singapore to Malaysia, and along the causeway were three large pipes. A local explained that two of those transported untreated water to Singapore. The third one returned some of the treated water back to the city of Johor in payment.

  31. Your comments about Von Neumann made me actually laugh out loud. "...probably while having breakfast or something" is something so accurate that can only be applied to von Neumann and Euler in my opinion

  32. As a specialized supplier we also helped ASML develop its in house capabilities for similar processing. It was amazing how they would defer to us, yet still demand perfection. They were very willing to pay well for what they got.
    129
  33. Is there any chance you could do a whole video on the production of ingots and the slicing process? You've done so many videos on lithography where you've touched on it, but for those of use not well educated on the topic, the slicing of wafers seems like an almost magical process, so a 'deep dive' on it would be awesome.

  34. Here in Peru most people knew about the existence of New Zealand because of the football intercontinental playoffs, but back in the 90's there was a milk brand from New Zealand called Anchor that had ads saying that the milk came from clean farms there, you still can find Anchor on some supermarkets here
    128
  35. Incredible year for your channel. I became a fan at the beginning of 2022 and have been eagerly watching the videos as soon as they come out since. The content that you make is truly special. It's not an easy thing to create longer form, information dense videos in this time when attention is such a hot commodity, but of any educational channel, your's does it best. I want you to know that your videos have made a real impact on me, truly inspiring me to be a better, more informed person. I see the hard work that you've put in, and I'm very glad that it's been so rewarding for you. Much love from Toronto.

  36. I mean given you were literally guts deep in ancient silicon origins, he's trying his best. But your insight is very much appreciated!

  37. We have two points of contact, on a good day. Our legs are pendula. Our ambulatory motion is essentially a constant form of falling forward. We rely on accelerometers inside our auditory canals. We shift our limbs, our superstructures, our very organs just to stay upright. We're a goddamn mess of an animal.
    126
  38. The honor you show your parents is so wonderful

  39. At this point retrieving magic fairy dust from the martian moon Phobos would probably be easier than the best alternative, if the martian moon Phobos had magic fairy dust.

  40. A related fact: Japan is consistently the US’s largest or second largest market for corn specifically because wagyu eat a ton of it during their incredibly long finishing phase. The US and Canada have similar two-tiered production systems between cattle production farms and fattening farms but their finishing phase is more like 3-6 months whereas Japan’s is a multiple of that.

  41. Diamond is used for the window through which plasma heating energy is injected into fusion reactors like ITER. This is because diamond is incredibly transparent over a huge range of frequencies, and the thermal conductivity is required to for cooling. They're also used for windows in other vacuum applications, of course, but pushing tens of megawatts through a 180mm diameter, 2mm thickness diamond window has to be the most amazing one. of course, these diamonds are polycrystalline, but still transparent. There's also a company making 100mm wafers of monocrystalline diamonds using a unique technology where the diamond isn't grown on a seed crystal, but on a Ir/YSZ/Si wafer. AuDiaTech in Germany. Supposedly the largest monocrystalline diamonds in the world.

  42. One correction, @11:30: "If that 450mm mirror was blown up to the size of the United States, 4500 km ... then 50 picometers would be just 0.4 micrometers." Actually, 0.5mm, which is pretty astonishing.

  43. Good overview. I left verification just after the Verilog revolution came to pass. We used hardware simulators at that point, with accelerated simulation. Sea-of-fpga emulation was not yet popular. The bottom line was that the company I worked for (nameless, but huge trust me) was new to hardware chip design. They had lots of money to buy toys, but had the idea that the tool would solve all. Thus the expectation was that the new, more expensive tool would relive them from the need to write test cases. I enjoyed being the one employee who understood the tools, but rapidly realized that it was a falling rock I had volunteered to sit under. I left the company soon after.

  44. Yay, thank you for this. I was always interested in the soviet union economy and nobody ever talked about it.

  45. Everybody in our engineering department, some in the maintenance, and a few managers are spending most of our time trying to improve yield in our product line. We sputter large 4x3 meter “objects”. A single defect can scrap a unit costing us several thousand dollars and all the wasted time. Since the line isn’t exactly screaming fast, this costs us millions. I am thankful that we have made great effort on this problem from many angles, including ones that I wouldn’t have thought of because we have a really talented team. I most recently finished a procedure for tracking down the cause of a single little scratch. Since the production line is over half a mile long, it was no small task. It took months to make a decent system so a future engineer will be able to make quick work of it. Tomorrow I will introduce new PLC software that will reduce processing times at one our bottleneck areas. I’m excited about that because my single software edit will save about $300-500k per year. We utilize chilled DI water for many processes, pure but not like the UPW in this video. Many places we use DIW for cooling high voltage electrical circuitry because pure water doesn’t conduct electricity, imagine that. In this video there is discussion about water purity to avoid sparking junctions on the wafer. I question how they prevent static charge build-up in the water itself.

  46. Man, the speed and consistency of your videos is amazing. Your's is one of the few channels that always puts out well researched videos that don't just sensationalize things for views. I checked your channel for a new video last night and knew that by the time I got up there would be a new one :)
    121
  47. I always love your videos. I hope you can get some rest and work at a healthy pace in the new year!
    121
  48. Thank you Asianometry, it is nice to see at least some YouTubers still aren't using AI voice models on there videos. It's getting pretty hard to detect now, "Scary interesting" as one example, but you can notice it if you pay attention to the emotional emphasis on how certain words are spoken in the context they are used. Keep up the great work!

  49. You do the best-narrated videos of all the channels i know. On the one hand you do really good, well-structured scripts to understandably explain complicated matters, without overly nested sentences and unnecessary technical jargon for example. And on the other hand you have a very pleasant way of talking, with a relaxed, not monotonous and not overly modulated voice, recording (at least) entire sentences at once (and by that always with the correct intonation), without cutting off the pauses (as so many others do these days), spoken in the right speed and by that giving the viewer enough time to process.
