  • Countries willing to pass on a US patent to China stop getting the chips (or, in this case, chip-making jobs, realistically, but that still hurts)

    Also Taiwan doesn’t wanna help China and even if a US sanction was just an excuse to hurt China and get away with it they’d probably do it.

    Edit: in this case, this chip is “foreign-produced items […] that are the direct product of U.S. technology or software”, according to the article. I feel it was implied but clarity is always good. US technology, used with permission in a Taiwanese good, and that permission could be retracted.


  • Depending on the specific game itself, we can boil down the multiple-stat problem in a few ways. If the goal is to get all the stats as high as possible evenly, then we can assign each stat a multiplier based on how low it is. Fixing lower stats becomes worth more than buffing higher stats. That multiplier would depend on the game, on how much it punishes the low stat. The multiplier itself might end up being a whole new problem to solve, but for now I’ll just say its not my problem and call it X.

    Whatever X is though, every stat can then be reduced to a single value using it. Super-low fortitude should be buffed over already-high mana according to X, so all of the numerical values in the game become directly comparable at any stage in this problem. Then I expect it will be equivalent to the knapsack problem. Each item in the game will boost several stats in certain ways, and all of those boosts can be combined using X to become our item value in the knapsack problem.

    So I consider it to be the knapsack problem + figuring out X (which might be NP-complete on its own, depending on the game).




  • Unions don’t work without a central state.

    If there isn’t an organization larger than a corporation making it keep to a line, a corporation will end up as a monopoly. If a line of work for certain skills is completely monopolized by one company, a union can’t ever get bigger than them to enforce anything. Its a stalemate that the company can end by training scabs and a union can’t end at all. That’s assuming the company doesn’t just start murdering Union heads which is probably the first thing they’d start to do without an organization larger than a company to call on.

    Of course, maybe we could unionize everyone into a people’s union, for the purposes of having a bigger entity than a corporation that can defend the people. Pay some Union dues to them to get some police-equivalent people to make companies toe the line. But corruption exists and while the USA isn’t really for the people today, that is pretty much how the USA started.

    Unions as we know them rely on regulations like anti-monopoly laws to exist.

    Although for the record I don’t hate anarcho capitalism, I just think it’s more of an ideal. A more realistic but comparable system would include a government to protect union rights and prevent oligarchical behaviors while still being mostly hands off on an industry with a Union, letting the union enforce safety and related guidelines.




  • They’re basically saying they won’t ship off data to be processed to anyone else. Apple server hardware will process it in data centers.

    There’s then a further promise that this hardware will be isolated from other things apple is doing, so that no other apple processes not related to AI will be able to see this data.

    So, for instance, some other AI company might cut a deal with Amazon, get a discount on AWS processing, and in exchange, let amazon snoop through the data being processed. Or, a company might use a cheaper process in an existing data center that isnt particularly secure, and just not care if its being spied on. I’m sure there’s more likely scenarios as well, I’m not a security expert, but apple is promising to thwart any similar thing, by promising the “cloud” for AI is a unique cloud, not just encrypted or whatever, but actually physically separate from everything else

    Its the equivalent of saying “this product won’t trigger your peanut allergy, we’ve built a facility that will never see a peanut, so cleaning procedures are easy and accidental contamination is impossible since this product is the only thing made in this factory.”

    These are still just claims though, not facts, so we’ll see.





  • So, you’re pretty much spot on with how emulators work. I also like using claymation to demonstrate it, like this. Your computer bends over backwards to give the game the exact environment it expects.

    What makes recompilation more than a simple script is the rebuilding aspect. I brought up claymation because it’s a great analogy for this, too. An n64 ROM is a complete set of characters, sets, and a script for a claymation movie. It’s I in one studio right now, and that studio is the N64, but you need this to be in your PC studio.

    First, you have to decompile your sets and characters. You take reference photos and rip out every tree in a forest set and roll each tree back into it’s own ball of clay, with its own reference photo each time. Every little clay cobble on a road, characters outfits, hair, limbs, you meticulously separate every piece of clay that Nintendo shaped, ball them up, and pack them. You now have a million little clay balls and reference photos for every one of them. You take these back to your PC studio. Thankfully, with these reference photos, your clay 3D printer (compiler) can return these balls into something very close to their original shapes, except there’s a bunch of little mistakes. One character’s leg is slightly thinner and longer than it should be, which messes up their gait when you re-film this, so you manually tweak the leg to be accurate. The cobbles don’t quite fit the same, they’re a bit smaller, but you have extra clay because of that so you just make more cobblestones. The road doesn’t look exactly like the original, but that’s fine. The trees, again, don’t quite fit right, but you’ve made similar trees in your studio before and you know those will work so you actually just use those as references instead of the originals. You get filming but this one scene just isn’t lit right, and you can’t figure out why, but you eventually figure out the N64 studio opened the blinds on their window to get natural sun in this shot, but your studio doesn’t have a good view of the sun at that angle, so you have to get a good lamp.

    You face a million little hurdles decompiling and recompiling. Its almost literally reinventing the wheel. Almost all the work goes into little details that almost seem unnecessary, but there’s so many that it’s absolutely necessary. I was watching a playthrough of a recompiled majoras mask earlier today, and the Dev of this project found his way there, too, and he said it took a few days to get majoras mask to decompile and recompile, and about a year to fix all those little details that in software become lag or new bugs. So the script guy isn’t really wrong when he said he could do it fast, but he definitely wouldn’t do it right.
