Yes, all models are wrong, some are useful, and the model math is using is evidently not very good. Probably there is a better one out there. Physics isn't reality but it does use "closeness to reality" as a metric for qualit

No, they're just plane geometry, albeit in a cludgy notation (which conflate vectors and rotation operators on vectors because they happen to be isomorphic in R^2). But plane geometry is a real thing.

Nevertheless it feels like the point of Banach-Tarski is that it proves math went wrong somewhere. Evidently the sets it's talking about are not objects which are interesting in reality.

Sure but the essence of it, the reason that it works, is that it shims a declarative architecture into JS. It works because it turns out UI programming works better in a declarative style.The fact that that involves managing state is second

Well it depends if you're talking about React the UI library or React the increasingly popular underlying architecture. The former is vastly more popular by usage (I mean.. I assume) but the underlying approach to declarative-in-impera

It has adequate performance and the ease of development is worth it not being the most performant way to do things.

That's backwards. React is a tool for writing declarative UI (or declarative anything really) that can handle state updates. Probably they're using it because it's the best tool around for that job.

No way, AI wasn't on the radar back then.

Seems like it would be a great feature on github, or for a standalone site, if a critical mass of usage could be reached and the site was trustworthy (i.e. not trying to monetize the information somehow).

That was almost exactly my point, that American 5-over-1s are bad not because they're 5-over-1s but because they're done badly. But it's more than just the car-centricness. It's all the other Americanisms as well.

Love the tone and the comments, personally.

of course it's my personal opinion, it's a post on the internet. But it's pretty obviously true also. So obvious, if you live around them, that IMO the onus for proof is on the person finding something good to say about them.

A bit, yes, but most of the community problems can be solved without changing that. The community problems are due to the way they're run: basically, owned by profit-maximizing hedge funds.

The main issues with them is that they are don't create much community, with their lifeless corridors and alienating common areas, and that the ground-floor retail tends to be (apparently) reserved for overpriced retail chains that com

Not really. Electrons are as far as we know not composed of smaller particles, and there's good reason to think they are elementary. Basically because smashing them with things reveals no smaller structure. Whereas when you smash thing

I feel like there isn't really, not anymore, and most of the semblance of a debate is people reporting on historical debates. Although hard to be sure without, like, a survey. At least in what I read it seems like the remaining debate

This article seems to get it backwards? > This doesn’t mean that the atoms themselves are smeared out like waves; rather, what spreads is the probability distribution of them being found subsequently in a given location No, it really do

well they do need to have names for things. you can't exactly do surgery on "the third muscle from the back".

So you're saying, because it can't be done perfectly, it's not worth doing at all? Seems wrong. Although otherwise I feel the same way about LLMs.

It is gross in general, but it's especially offputting on a product that is otherwise sorta likable and cute. Like it's one thing if a hotel website does it because you expect them to be scummy anyway (not ideal but that's ho

The website tries to tell you every time someone buys one, like some kind of creepy attempt at peer pressure.

The times here seem unreasonably bad even with the bad algorithm. Something else has got to be going on. Maybe kind of hidden factorial complexity when it tries every combination?

Neat. But somewhat confusing that it's missing some common plants. (A few I found: honeysuckle, broccoli, turnip, jalapeno, kale.)

Sometimes it feels like the trend online right now is to design everything to make you stupider, on the theory that if it asks less of you will go along with it more easily. For instance, Google results seem more "least common denomina

I felt like it made total sense when I understood the idea of a basis, plus "sinusoids are a basis for (a class of functions)" Everything else basically follows from that. The Fourier transform itself integrates (in one notation)
