In-reply-to » I finished all 12 days of Advent of Code 2025! #AdventOfCode https://adventofcode.com — did it in my own language, mu (Go/Python-ish, dynamic, int/bool/string, no floats/bitwise). Found a VM bug, fixed it, and the self-hosted mu compiler/VM (written in mu, host in Go) carried me through. 🥳

@prologic@twtxt.net How on earth did you do that so quickly, especially day 10? People were struggling with this a lot. 🤯

I cleaned up all my of AoC (Advent of Code) 2025 solutions, refactored many of the utilities I had to write as reusable libraries, re-tested Day 1 (but nothing else). here it is if you’re curious! This is written in mu, my own language I built as a self-hosted minimal compiler/vm with very few types and builtins.

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 » My current PC is from 2013, so I never even bothered to check, but as it turns out: My motherboard still has a serial port. 🤯 I thought these had long died out by then. To be honest, I didn’t have the need for one, either, not until recently … So I completely lost track if PCs have these things or not.

Bought more cheap slot plates (with bad reviews and people complaining about the pin order, because I could’nt find a product without such reviews), but those are simply correct now and just work. 🤪

I’m seeing crashes in the 3D subsystem. (Gallium? Glamor? Whatever other Mesa thing they have? No idea.) In the logs I find this:

malloc(): unaligned tcache chunk detected

And that’s why I still care about Rust and want to learn more about it, even though it’s giving me so much headache and I’ve given up so many times. Because Rust currently seems to be the only popular systems programming language that tries to eliminate these error classes.

And of course “the Rust experiment” in the Linux kernel has recently been concluded as “successful”, so that alone is reason enough for me:

Awk to take lines from Plan 9’s /lib/unicode and prepend the actual glyph and a tab: awk ‘{cmd=sprintf(“unicode %s”, $1); cmd | getline c; printf(“%s %s\n”, c, $0)}’

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.

i’ve learned a lot of lessons from writing my notes app, gonna apply this to bbycll and refactor the code to make it way more legible cause my custom templating system is only kind of a giant mess

In-reply-to » @bender yeah, I've been reading through the documentation last night and it felt overwhelming for a minute... +1 point goes to GTS's docs. but hey, I'll be taking the easy route: podman-compose up -d they provide both a container image and an example compose file in a separate git repo but I'm wondering why that is not mentioned anywhere in the docs, (unless it is and I haven't seen it yet)

@aelaraji@aelaraji.com not to mention you wouldn’t be able to, anyway (if you’re going to use the same domain between backends)

In-reply-to » I'm contemplating the idea of switching my activity pub instance from Gootosocial to a Pleroma one. While GTS is kinda cute (lightweight and easy to manage) of a software, the inability to fetch/scroll through people's past toots when visiting a profile or having access to a federated timeline and a proper search functionality ...etc felt like handicap for the past N months.

In-reply-to » I have a question! I'm looking for a small personal camera(specifically good for videos because that's what I'll use it for) that's cheap enough for a teen to afford but also actually good. Do any of you tech people have any good recs?

@bender@twtxt.net a mobile phone camera doesn’t cut it because it cant take long videos. I would say like the cheapest possible tbh! it doesn’t have to be an amazing grade a camera, just something that will record in decent quality for long periods of time! I mostly want it to make vlogs :p
