  • Yes! The way those physics models are created is so cool. The article somewhat explains it, but it’s mostly a fluff-piece for things unrelated to genAI. More in-depth:

    The physically accurate simulation is great but slow. So we can create a neural network (there’s a huge variety in shapes), and give it an example of physics, and tell it to make a guess as to what it’ll look like in, say, 1ms. We make it improve at this billions of times, and eventually it becomes “good enough” in most cases. By doing those 1ms steps in a loop, we get a full simulation. Because we chose the shape of it, we can pick a shape that’s quite fast to compute, and now we have a less-accurate but faster simulation.

    The really cool thing is that sometimes, these models are better than the more expensive physics simulation, probably because real physics is logical and logical things are easier to learn.

    We’ve done things like this for ages. One way we can improve them is by giving them multiple time steps. Unfortunately they kinda suck at seeing connections over time, so this is expensive. Luckily, transformers were invented! This is a neural network shape that is really good at seeing connections over one dimension, like time, while still being pretty cheap and really easy to do run in parallel (which is how you can go fast nowadays).

    With a bunch of extra wiring, transformers also become GPT, i.e. text-based AIs. That’s why they suddenly got way better; they went from being able to see connections with words maybe 3-4 steps back, to recently a literal million. This is basically the only relationship with “AI” this has.

    I mean yeah that’s pretty much it. My dad’s cooking is unseasoned cucumber in a pan with some grocery-store veggie balls, which is not enough for 2-3 people. My mom’s cooking is much better, but it’s cooked more out of expectation than enjoyment. Eating together is expected but not enjoyed for its own merits afaik.

    Desserts are the exception usually. Still, it messed up with my relationship to food, made it a lot worse than it could have been. Eating full meals with someone makes me gag, I have trouble eating normal quantities.


  • It’s not intentional. There’s tons of times where I’ve acted poorly because I was hungry, and even if I’m aware of it at the time it doesn’t help much.

    More things feel like personal attacks, you have less self-control, and generally you get more emotional. In retrospect, sure, I know I’ve acted like a dick, but when you’re hungry enough that you can’t think straight…

    Trans woman who pays a bit more attention to mannerisms than most people, both in men and women.

    1. Yes, it’s a real thing
    2. It’s at least 90% men, and I’m being generous
    3. It’s not most men that do it (especially in the sillier ways)
    4. Size matters not

    Picture a teenager in black sweatpants and a hoodie, on his own in a bus. That’s the most common I think. It’s generally men who try to project an image of strong masculinity or coolness. They don’t really do it with other people because it’s silly. It might be an unconscious thing, idk. It still looks stupid. It’s mostly men because it’s a masculinity thing.

    It’s great if you don’t do it, and I wouldn’t be surprised at all if you didn’t. But there very much is a type of guy who does it. And there is no common type of woman for that specific behavior.



  • Proposal: have a shorter way to write “global time” (or you could have, say, 4 quarter-global times), the same way we have C, F and K for temperature, then make that a more common way of communicating time.

    Yeah UTC kinda does that but nobody uses it like that. Shorten it to U and it’s much punchier. Also abolish daylight savings, too confusing.

    If you don’t wanna bias to europeans too much, use the international date line.
