  I mean comparatively to HDDs.

  Of course there are also challenges to making a high capacity SSD, but i don’t think they are using fundamentally new methods to achieve higher capacities. Yes they need to design better controllers and heat management becomes a larger factor, but the nand chips to my knowledge are still the same you’d see in smaller capacities. And the form factor has the space to accomodate them.

  If HDDs could just continue to stack more of the same platters into a drive to increase capacity they’d have a much easier time to scale.

  How about a 122.88tb SSD? Large SSDs are pretty common in the enterprise market and arguably much easier to manufacture since you only need to put a bunch of nand chips on a pcb.

  Your claim that they would advertise it is speculation. What would be the purpose of that?

  To advertise that they can? In return what would be the purpose to hide it?

  They do seem to make their advancements at least somewhat public, e.g. with their recent progress with a EUV light source.

  I am probably on the pessimistic side and you maybe on the optimistic, so the reality will likely end up being somewhere in between (but only time will tell).

  China will do this because they have massive talent mass and ressources, and because they have to.

  Well it also was developed in the west by a large amount of talent and resources and still took a lot of time. But you are absolutely right that their hand is being forced.

  Restricting exports like this imo was a huge mistake, imo especially in regard to duv. In the end it might have achieved some damage in the short/medium term, but that wasn’t anything the us could capitalize on and it also directly hurt ASMLs profits (meaning less resources to advance). And regardless how the timeline ends up looking on the end (be it closer to your or my prediction), physics are the same everywhere so that can’t be restricted and they will eventually be able to figure it out.

  GAA is the next evolution of transistor architecture from FinFET, but as far as I know has no direct link to smaller process nodes. In that (to my understanding) it doesn’t require small nodes and could be used just as easily in larger ones. It’s just that it is more difficult so until now there were other easier ways to make progress. However with new nodes getting more expensive and giving less scaling gaa and other things like backside power delivery are being pursued.

  We will have to see if the process is actually good, but I have little doubt that China will become competitive in EUV within 5 years. But if they have it already next year, that will be very fast.

  So not only do you expect China to have a working domestically produced EUV machine within 5 years, but a competitive one? Or possibly even next year?

  Next year is just pure fantasy that I don’t think even the most optimistic would assume. If they were anywhere close to that we would already know. They’d have shown a working prototype by now.

  Euv is crazy difficult and you not only the result of a single company ASML, but many highly specialized companies that are leaders in their respective fields and all over the world like e.g. Zeiss for for the lenses. So for China to replicate it domestically they’d need to copy the whole supply chain. Which is orders of magnitude more difficult than what they’ve done in other industries like electric vehicles or solar panels.

  Imo if they have a working prototype of a complete EUV machine within this decade it would already be impressive. But that would still be far off from mass production or wherever the industry is by then (Intel is currently trialing high na EUV). Also for reference Wikipedia says ASML had their first prototype in 2006 and we know how long it took to being that to mass production. China as a second mover might have an edge that speed things up, but just knowing how it works in theory isn’t enough and there are o shortcuts.

  But maybe they also pursue another technique such as nano imprint (like canon) to achieve smaller nodes. Maybe that would be easier to replicate without existing global supply chains.

  Well there are claims that Huawei is aiming for 3nm with GAA with tape out next year See Here.

  I think we shouldn’t forget that the nm numbers really are just that: Numbers. They don’t correspond to any specific measurements and can be chosen more or less arbitrarily. So 6nm for example might just be a slightly refined 7nm node.

  Another thing is power efficiency and yields. If they get 4060 performance at terrible yields and with massive power draw then it is very different to getting there at similar parameters as Nvidia.

  If China does end up cracking EUV by themselves it would indeed be massive. It’s arguably one of the most complex things mankind has ever done. But there are so many factors to get right that tbh I don’t see it happening any time soon.

  There’s currently a Kickstarter going on for a watch that aims to be modular and repairable. It’s called UNA Watch.

  Look interesting, but imo with these things it’s a bit of a chicken and egg problem, where the upgradeability/repairability only has value, if it is actually provided in the future (and economically viable). Something that can only be proven in time, but requires people to trust it before.

• ⁨Comment⁩ on ⁨It Might Be Time to Admit the Great VR Experiment Has Failed⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  I find it’s at least theoretically in the right spot for mass adoption. Something like a valve index or bigscreen vr paired with a strong gaming PC would of course offer a much better experience. But thats just not realistic for the masses.

  Also Apple failed with their expensive premium device (although I guess it was always kind of a dev device sold to the masses).

• ⁨Comment⁩ on ⁨It Might Be Time to Admit the Great VR Experiment Has Failed⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

  It’s certainly debatable, but at least for the price it offers a lot imo.

  The quest exclusives are of course frustrating, but it makes a lot of sense from a business perspective, considering Meta is trying to position themselves as the VR platform (similar to say android with smartphones).

• ⁨Comment⁩ on ⁨It Might Be Time to Admit the Great VR Experiment Has Failed⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  If you don’t mind Meta/Facebook, then the oculus quest headsets are also very affordable hardware and deliver a good experience. I think the issue lies with content.

  Smartphones or handhelds like the steam deck with flat screens could use plenty of already existing content made for screens. With VR you want different content that is made specifically for it. There is a decent amount of games (but still much fewer than for other devices), but honestly not that much more.

  Additionally it also can only really be used at home, where most already have other devices.

  It’s a chicken and egg problem. But imo if there were more genuine unique productivity tasks and experiences available through VR, we would see more adoption.

• ⁨Comment⁩ on ⁨Crypto exchange Bybit says a hacker took control of one of its cold Ethereum wallets, resulting in what analysts estimate was the loss of ~$1.5B worth of tokens⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  What I don’t quite understand is how there is 1.5 billion in a single wallet. Or how are these things structured?

  This article puts their total assets under management at $15.7b, which are held in different cryptocurrencies with ethereum at just above $5b.

  So I am wondering how they have more than 1/6 of their Ethereum in a single wallet or were these multiple that were connected and got compromised through the same vulnerability? How expensive is it to have more individual wallets? Would it not be feasible to have it split in something like $100m chunks? Or any other more moderate size.

• ⁨Comment⁩ on ⁨Landing page for all my services⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:

  That’s pretty much me aswell, besides that I didn’t even spend energy to try and learn others. Simple docker compose, simple ui and easy way to add services.

  I am sure there are alternatives that allow for more elaborate setups and fancier things. But for the low effort I put into it, I got a page with some nice buttons with appropriate icons that scales to whatever screen size it’s displayed on. Only additional thing I did was enabled to show some basic info to see if e.g. SABnzbd is downloading something, which was also super easy.

• ⁨Comment⁩ on ⁨Can I lose a beer belly working out one day a week?⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:

  Yep. Weight is lost through diet, sport might help but can also make you hungry. The main benefit of exercise is better health through increased fitness.

  People should compare how much calories exercising burnes per hour compared to the simple act of e.g. switching sugary drinks for water. Especially when you aren’t fit to begin with, meaning you won’t for example be able to run for hours each week.

  Intermittent fasting definitely is a good method. But it varies for everyone. Imo it helps to start with changing what you groceries you buy. At least to me the further away from the plate you implement caloric reduction the easier it is.

  Thanks for the thoughtful reply, those are definitely some good arguments. Sadly you are probably right that in the end no matter the rules companies will try to game them as much as possible.

• ⁨Comment⁩ on ⁨Boeing Has Lost a Staggering Amount of Money on Its Starliner Catastrophe⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:

  Makes one wonder why fixed price contracts aren’t more common compared to cost plus, with this being the perfect example in their favor.

• ⁨Comment⁩ on ⁨Dell kills the XPS brand⁩ ⁨⁨5⁩ ⁨months⁩ ago⁩:

  Imo this kind of shows the basic problem with the xps line. As I understand it it was basically the premium consumer line, not something meant for business use. Meaning it had the nice specs on paper, but not the durability you’d need in a setting with extensive use and where downtime means serious money. But as you demonstrate this distinction was to blurry.

• ⁨Comment⁩ on ⁨Dell kills the XPS brand⁩ ⁨⁨5⁩ ⁨months⁩ ago⁩:

  Yeah, sadly everything has to sound fancy. Imo this is partially to blame on consumers, but I do wonder how much of it is basic psychology vs induced demand that could be reversed if a company would stick with sensible product names for a while.

  Instead of basic they could also go with something like “essential” or “home” that maybe have slightly less negative associations.

• ⁨Comment⁩ on ⁨The Great Migration to Bluesky Gives Me Hope for the Future of the Internet⁩ ⁨⁨7⁩ ⁨months⁩ ago⁩:

  For me the bigger value is not in the quality difference between the two platforms. And don’t get me wrong, i agree that BlueSky is a lot better than Elon’s Twitter, but not as good as a decentralised Fediverse Platform.

  The real positive is in the act of migration itself, because it shows that is still a possibility. So hopefully it proves sustainable.

  Is YouTube doing it with small creators actually in mind? Who knows, other than them?

  I am pretty confident in guessing that they are not doing it for selfless reasons. Imo the reason is that the less information they give the user, the more you are beholden to the algorithm choosing for you.

• ⁨Comment⁩ on ⁨China debuts a record-smashing 26 MW offshore wind turbine⁩ ⁨⁨8⁩ ⁨months⁩ ago⁩:

  I am not sure how up to date and accurate this Wikipedia article, but that seems like another substantial step. Looking at the list I am quite surprised by the speed the scale of these wind turbines seems to progress.

  Can someone more knowledgeable answer me some questions:

  How likely is it that China takes over this industry world wide similar to solar? Specifically what role does (if at all) play logistics in this. Those turbines are massive compared to easily shippable solar panels. So I imagine they’d be much harder to transport and local production could have some advantages, but how much does that matter?

  It does seem like all the new largest turbines in prototype phase are from China, but when you scroll to commercially deployed the western manufacturers show up more. Is this just due to different timings in their development cycles or have they dropped out of development for larger turbines?
