Spitballing here, but I suspect it's a density thing. If you are considering all prime powers up to some bound N, then the density of prime powers (edit: of size p^n with n > 1) approaches 0 as N tends to infinity. So rather than th

I've never considered something like this before. I like the way you've phrased this too. I'm going to give this a shot for a few weeks.

Just speculating here, but isn't it quite possible someone wasn't intentionally sitting on it for 14 years and instead just couldn't access it? For example, if they've been sitting in prison this whole time. Something li

They recently gave out some 3-month free trial vouchers for users to give to friends. I have a spare one that I’d be happy to share with you if you’d like. Though I don’t know the best way to get it to you since I don’t think HN has DM func

Not sure on the accuracy or if it applies to you, but prior to getting the septoplasty my ENT did mention it might not make a big difference if overweight or obese and so often doesn’t recommend it in those cases. For comparison, I used som

With the exception of losing weight (already a 22 BMI) I tried pretty all of this to no avail. Turns out I had a deviated septum and surgery fixed the problem. As a bonus, I can easily breathe through my nose now.

When I first learned two's complement I sort of accepted it as something to memorise for a test and didn't really understand (or care) why it worked. What really made it click for me was thinking of it as modular arithmetic. If yo

I’m curious why you think mathematics doesn’t need to be covered here. Immediately after covering the maths background, the author jumps into elliptic curves and I can’t think of how to understand that without understanding a little bit fin
