Corollary: P does not mean easy. Most things that you do on the computer, you want to be O(n) or less; maybe O(n log n) or even O(n log^x n), but no slower than that. That means if you get a bigger problem, you can generally just get a prop

I think it's funny that the majority of causes you list (isolation, not enough physical activity, little vitamin D/Sun exposure) wouldn't apply at all to the group you cite as having widespread issues (girls HS volleyball tea

Grope has the same meaning in American English, and used in that context could be fine ("grope around"). But I have never heard "groper" used for anything other than some engaging in sexual assault. The benign sense of &

Yeah, I was responding to the "why wasn't it ever official even when it was reasonably popular", not why it's not now. Those threads I linked to were from 10 years ago or more. I tried looking for any direct discussion i

I have had one issue related to systemd; at one point when doing a routine update there was some dangling symlink issue that caused systemd to crash. This wasn't catastrophic; a lot of things didn't work, but I was able to cleanly

Generally, the displaced threshold is not because of the load of touching down, but because of clearance of obstacles. When landing, where you are aiming to land, and a standard glideslope, puts you over obstacles at a certain height. In so

It's true that energy density of batteries is a lot lower than gasoline, but electric motors are a lot more efficient. It doesn't make up the whole difference, but it does make up some of it. Also, battery technology is improving

Ah, sorry, I'd missed that you were discussing completely synthetic fuels. Yeah, those are a possibility, but a lot further out; those are not going to be showing up in production quantities in the next 5-10 years. And an ICE engine is

Growing crops for biofuel is more land intensive, and thus involves cutting down more forest and removing carbon sinks, than the equivalent solar power. Yes, bioruels are better than fossil fuels, but worse than clean electricity. Anyhow, i

JWTs are the poster child of fragile signature design. If something is like JWTs, you should reconsider. Many implementations allowed JWTs with a null signature scheme, completely bypassing any security!

Advertising and selling a feature that you don't have sure seems like fraud to me. If it's "the feature is nearly ready but just needs some polish" there's an argument to be made that maybe you were just being a bit

I don't think "promoted" is the right way to look at it. That kind of implies some kind of paid marketing campaign, while as far as I can tell, the interest in Rust tends to be organic. The thing is, Rust is a bit more novel
