I remember working on homework for "Discrete Computational Structures" (had to look it up ) in undergrad and having to come up with that sum of sequence of odds is the sequence of squares trick (it becomes clear if you visualize 4

I'm a little behind where you are (bad assembly knowledge) and I've always thought my next steps were learning about SPI and I2C, if that helps.

Ah so you were a bulk sender. Yeah that's pretty fraught; AFAIK for Gmail you have to follow their bulk sender guidelines [0], which is a pretty long list of things to do. Not impossible though. But, again most people aren't sendi

I don't want this to turn into a big support thread, but I'm always surprised by this stuff. It's not like the algorithm has some case for small services like this, like Google's spam detection is heavily based on "

Online grooming is obviously very bad, but it doesn't seem like it's happening very much. Hope for Justice reports ~8,600 cases in 2022 [0], but there were 72.5 million kids in the US that year [1], so that's just .01% of kid

I think the general premise is housing can't both be so cheap that people with nearly no net worth can get it, but so valuable that it can serve as a substitute for retirement savings. This is from first principles true, but it's

Maybe this'll come off as snarky, but I would build Excel! It would spread 10 million requests across the 10 million users, be totally immune to network outages, and my users could rest assured I wasn't thumbing through their data

I (of course) wanna plug Vim again here. Vim comes with a great terminal, you can arrange the windows however you want, you can save the layouts in your sessions, and the keybindings for doing all of it are real straightforward. I used to u

Yeah that's probably too much of a slog. It's probably the case that very few things would break if you just snuck the validation out the back door and added like u8str (or whatever) that did the validation for people who want tha

I'm pretty well convinced at this point that specifying an encoding for a system language's string type is probably too constraining--and like you point out, often commits the sin of requiring unnecessary processing. Your CSV exam

I'm doing some NNTP-related work and hadn't looked seriously at Nostr until just now. It looks like the main benefit is just that it signs events, is that right?

The Go thing (+ invalid sequence conversion) is a really good point. If OP's point was "don't validate just convert invalid sequences when you need to" or "think twice before forcing validation into your primitive s

"\033[31;1;4munderlines\033[0m" is (again) no worse than a stream of vertices or a stream of object code. Everything is a stream of bytes (well, a stream of bits anyway). Do you want CSS? Lipgloss is not too far off [0]. I read yo

You need to know about Unicode to use Unicode regexes; if you want to pass invalid UTF-8 into these engines you have to give up Unicode regex support; i.e. how would you match "\p{East Asian Width:Narrow}" on an invalid UTF-8 stri

You do have to validate UTF-8 strings: - You can't just skip stuff if you run any kind of normalization - How would you index into or split an invalid UTF-8 string? - How would you apply a regex? - What is its length? - How do you deal

There are libraries and frameworks that abstract this for you: ncurses, bubbletea, etc. At some point, every interface is low-level: GPU geometry is a stream of vertices, a program is a stream of bytes. This isn't some terminal-specifi
