The "browser" is a blank execution sandbox with a rendering context. The remote server sends programs (using something like WASM) with a standardized ABI. The program can use the rendering context to put stuff on the screen or rec

Gold has properties that are similar to copper (highly electrically and thermally conductive, lustrous, and malleable), with the added benefit of being corrosion resistant. Many of the industrial applications of gold and copper are similar.

Fair point. Async is a big enough idea that it probably warrants designing the language with it in mind. I guess another way of phrasing it would be that it violates the "there's only one way to do it" maxim, and the "tw

What specifically is the problem with asyncio? I quite like using it, so I'm curious if there's some aspect that makes it unsustainable?

The main point I'm making is that the information density of the physical world is not unlimited as GP suggests. But I think that example just shows how few bits you can really get out the exercise!

I think there are at least two things wrong with this take: One is that I don't think it follows from the premise that the continuity of the physical world precludes AI, brain scanning, etc. Even if the physical world were continuous (

The distinction between "adding" and "removing" a postulate is an important, non-arbitrary one. The "worlds" are there in both theories; Copenhagen adds a new phenomenon (non-unitary evolution) which makes so

I don't think this criticism is correct, at least in response to what was said. Yes, a classical bag containing classical balls doesn't reproduce quantum behavior, because of Bell's theorem. But GP's description isn&#x27

If you're vaccinated, it's rare to get it. If you get it, it's likely to be mild or completely asymptomatic. Basically no one who's been vaccinated has died.

It seems unlikely that we would try to colonize other star systems by sending meat there— meat doesn't keep well over the necessary time scales. It seems a better plan would be to send artificial intelligence which can remain dormant f

Yes, by our current cosmological models, we are in a very young universe. We don't really know, but it may be the case that the universe is only conducive to life during this phase of its existence.

I see. I'd say it depends what the application is, then, because in graphics correctly handling (unlikely) extreme values would be quite secondary to performance, especially for an inner loop function like norm. See fastinvsqrt, e.g.,

What would you do differently with the norm function?

It's sort of analogous to "thrashing" in computer software. Once a resource is overtaxed past a certain point, the inefficiency of being in an overtaxed state causes the system to handle the load even worse than in normal con

It's this one. Starlink is an easy way to make oodles of money, which they can redirect toward getting to Mars. They can launch their satellites at cost (or less, if they sell ride sharing). No other telecom can do that. And their cust

They need LIDAR or stereopsis. IMO stereopsis could probably do a better job than LIDAR much more redundantly, and for a tiny fraction of the cost. But neither is insane to me. Structure-from-motion is all you could get with monocular vis
