I just completed “Gift Shop” - Day 2 - Advent of Code 2025 #AdventOfCode https://adventofcode.com/2025/day/2 – But again, I’m solving this in my own language mu that I had to build first 🤣

@prologic@twtxt.net Whoop, whoop! Nice! And welcome back. 😅

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:

I just completed “Secret Entrance” - Day 1 - Advent of Code 2025 #AdventOfCode https://adventofcode.com/2025/day/1 — However I did it in my own toy programming language called mu, which I had to build first 🤣

That’s the right answer! You are one gold star closer to decorating the North Pole. [Continue to Part Two]

Whoo! Making progress! With AoC 2025 solutions implemented in my own toy language 🤣

Ahh that’s because I forgot to call main() at the end of the source file. mu is a bit of a dynamic programming language, mix of Go(ish) and Python(ish).

$ ./bin/mu examples/aoc2025/day1.mu 
Execution failed: undefined variable readline

Come back from my trip, run my AoC 2025 Day 1 solution in my own language (mu) and find it didn’t run correctly 🤣 Ooops!

$ ./bin/mu examples/aoc2025/day1.mu

And I’m back from my holidays! 🥳 Back to work boo 😒

Alright, Advent of Code is over:

https://www.uninformativ.de/blog/postings/2025-12-12/0/POSTING-en.html

It’s been quite the time sink, especially with the DOS games on top, but it was fun. 🥳

In case you’re wondering: All puzzles (except for part 2 of day 10) were doable in Python 1 on SuSE Linux 6.4 and ran in a finite time on the Pentium 133. Puzzle 10/2 might have been doable as well if I had better education. 🤣

Right at sunset we went for a quick stroll into the woods. Cannot complain about the colors in the sky: https://lyse.isobeef.org/abendhimmel-2025-12-12/

@shinyoukai@neko.laidback.moe Time to become a trixie or forky!

@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.

@shinyoukai@neko.laidback.moe is that https://github.com/owncloud/ocis (Go based, instead of PHP 🤮)?

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)}’

Once a bookworm, always a bookworm.

@lyse@lyse.isobeef.org 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 Anytime! Glad you like it, too. :-)

@lyse@lyse.isobeef.org It was too late when I read the “Addictive” warning… 😆 Thanks for sharing this!

@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.

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)

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

yarn stop logging me out challenge (impossible)

it is really annoying and degrading to find that you need to upgrade to payed subscription to enable 2fa on your account, cmon ppl those are basic things…

Yo @prologic@twtxt.net, apparently even ‘git clone’ is getting blocked by your Gitea or something (I’m using authentication, naturally)

Day 6 of AoC, and I’m all caught up. 12 puzzles down, 12 more to go!

くそっ、「会話」、このアプリは一体何なんだ？

@shinyoukai@neko.laidback.moe yeah, that’s the only reason why I use sub-domains when trying anything federated (I believe Matrix has the same problem), in case things didn’t go as planned I can just migrate and take it down.

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

@bender@twtxt.net 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)

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.

@prologic@twtxt.net
Interesting experiment for salty-chat, use the MQTT protocol instead of HTTP, in theory it shouldn’t make a difference, at least

I’m gonna ask here again because I’m really frustrated and literally no one else is responding anywhere can u guys please help me find a good video camera the biggest think I want is long battery life but I also want it to be cheap like under $200, if you yourself don’t know please ask a friend because I am not a tech nerd and looking for stuff like this is very hard for me

The YAML forbidden knowledge of yarnd

Posting in anachronistic order, hah!

Got back into drawing! :)
I also made a couple (digital) collages today. Huge achievements

@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

save 100% today when you don’t buy anything

@prologic@twtxt.net do I just have to actually post the token into the twtxt timeline for the bridge?

(as in, for registration)

Hey @prologic@twtxt.net 👋

@c350a5e5fb9d9457@bridge.twtxt.net Does this mean we’res starting to work, this whole Twtxt <-> ActivityPub bridge thingy? 🤔

@prologic@twtxt.net Your gitea thinks the LICENSE file in the yarn repository is SSPL-1.0 instead of GNU AGPL 3.0,
and I can’t help but giggle at that

Alright, this yarnd installation has been properly fixed.

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?

@prologic@twtxt.net yeah, I’ve had even requested access to it in order to give it a try and report whatever I can but, Sorry I never got to do any of it. 2025 slam dunked a massive pile of 💩 over my life (hence the disappearance, trying to avoid talking about any of it) and I’m just starting to recover (or at least trying to).

Better Technology, Worse Motivation: GenAI’s Mediocrity Trap

While generative AI (GenAI) promises productive efficiency, it can paradoxically lead to lower-quality work. We conducted an experiment with professional illustrators and found that AI assistance flattens the quality curve—it accelerates initial gains but sharply diminishes the returns on sustained effort. Faced with this, a significant number of professionals made a strategic choice: they sacrificed the final quality to save time.

From http://www.jin-li.org/uploads/1/1/4/5/114595093/ai_and_motivation.pdf

I haven’t read this and can’t vouch for it; seems vaguely AI-boostery. Still, the conclusions are interesting. This seems to be the picture that is emerging about generative AI generally: most people don’t like it and find that degrades the quality of work. Coders seem to like it and think that it helps them, but in fact it makes the slower, less productive, and more bug prone.

By all measures it’s a bad technology. We should just be honest about it. There is no need to make excuses for multi-trillion-dollar corporations.

PSA: Just in case you start getting 5xxs on my end, I’m not dead 😂 (well, unless I am). Well be changing ISPs and hopefully get the new line up and running before the old provider cuts us off.
