Ha! Certainly none of us will get anywhere close to this bound, no matter how much time we log in Anki. But the OP asked "Would an infinitely-long-lived, but forgetful person be ab…

More than semi-fallacious - the math doesn't add up, because you run into the Bekenstein bound, which limits how much information you can pack into a volume.

Ah, I misunderstood you! I apologize. :)

That's not how arguments from contradiction work. You've assumed H (halting problem is decidable), prove B (beauty decidable), then say "but actually !H, therefore !B". All you've …

I might be missing something - why would this be a breakthrough? It sounds complicated to generate the interfaces, sure, but is there a theoretical problem blocking this, or just p…

https://www.microcovid.org/ is a similar tool, with more knobs to adjust risk factors (distance, outside vs inside, the other person's risk profile, etc.). Friends living in shared…

This is really upsetting. I didn't go to TJHS, but the sense I got from the three people I know who did was that it had that critical mass of nerdy science-and-tech-obsessed teenag…

Perhaps it's consistent with computation being done in many "parallel universes," but with heavily restricted communication - in this model it's almost trivial to parallelize work …

Have there been attempts to measure modern compilers' ability to optimize large programs against "perfect" machine code? The few times I've poked through demo scene binaries, I've …

It seems like a common misconception that humans have some secret power to solve undecidable problems that computers lack. But "this problem is undecidable in general" doesn't mean…

That's a good point! I guess you'd still have to make sure that variants with alignment requirements don't get unaligned. One way to do that would be to add leading padding if they…

If you want random access into an array of enums, you need them all to be the same size (there are also alignment concerns, which is why it's tough to use only 1 bit of overhead to…
