In-reply-to » Day 9 also required some optimizations, if you aren't careful, you end up with really inefficient algorithms with time/memory complexity beyond what a typical machine has 🤣

@movq@www.uninformativ.de I shrank Day 9 Part 2 from “cover the whole map” to “only track the interesting lines.” By compressing coordinates to just the unique x/y breakpoints, the grid got tiny. I still flood-fill and do the corner-pair checks, but now on that compact grid with weighted prefix sums for instant rectangle checks. Result: far less RAM, way less CPU, same correct answer.

In-reply-to » @lyse I swear, Her vlog is all I needed to cleanse my soul! Full of pure human interactions (whenever there is any), No BS No pretending and No Nonsense. Again, Thank you!

@aelaraji@aelaraji.com Yes, exactly. It also blows my mind that with sooo much less budget and equipment, her videos are way superior to productions of big TV stations.

In-reply-to » Man, I have no idea where the last build of the Yarn android client went to (even though it wasn't all that good when I first used it, but it was relatively useful otherwise)

@shinyoukai@neko.laidback.moe it was a mess, we are better without it. Until a new mobile client comes (not holding my breath), Yarn is very usable on the mobile, just using the browser.

In-reply-to » In case you haven’t seen it yet:

@prologic@twtxt.net Here you go:

(LTT = “Linus Tech Tips”, that’s the host.)

LTT: There was a recent thing from a major tech company, where developers were asked to say how many lines of code they wrote – and if it wasn’t enough, they were terminated. And there was someone here that was extremely upset about that approach to measuring productivity, because–

Torvalds: Oh yeah, no, you shouldn’t even be upset. At that point, that’s just incompetence. Anybody who thinks that’s a valid metric is too stupid to work at a tech company.

LTT: You do know who you just said that about, right?

Torvalds: No.

LTT: Oh. Uh, he was a prominent figure in the, uh, improved efficiency of the US government recently.

Torvalds: Oh. Apparently I was spot on.
