My little toy operating system from last year runs in 16-bit Real Mode (like DOS). Since I’ve recently figured out how to switch to 64-bit Long Mode right after BIOS boot, I now have a little program that performs this switch on my toy OS. It will load and run any x86-64 program, assuming it’s freestanding, a flat binary, and small enough (< 128 KiB code, only uses the first 2 MiB of memory).

Here I’m running a little C program (compiled using normal GCC, no Watcom trickery):

https://movq.de/v/b27ced6dcb/los86%2D64.mp4

https://movq.de/v/b27ced6dcb/c.png

Next steps could include:

  • Use Rust instead of C for that 64-bit program?
  • Provide interrupt service routines. (At the moment, it just keeps interrupts disabled.)

2025 end the year rewind:

Compared to only 3 new artworks in 2024 and next to no work, on other projects, this year I not only met the self-imposed goal of monthly pixelart, but exceeded it by 50%, with 18 additions in total.

Relicensed the majority of canine faction owned art and projects, under two less restrictive Creative Commons licensees*. This also applies retroactively, to everyone who used/archived our art and projects, back when the old license didn’t allow it.

Disappointed by the current state of the Internet and continued lack of competition among browsers, completely reworked the main website* and made Smol Drive** (a new image gallery project), both made to be compatible with as many web and Gemini browsers, as possible.

In-reply-to » Wow, @movq, so many tables. No idea what I expected (I'm totally clueless on this low-level stuff), but that was quite an interesting surprise to me. https://www.uninformativ.de/blog/postings/2025-12-21/0/POSTING-en.html

@lyse@lyse.isobeef.org I was surprised by that as well. 😅 I thought these were features that you can use, but no, you must do all this.

By the way, I now fixed the issue that I mentioned at the end and it works on the netbook now. 🥳

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.

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 🤣

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. 🤣

In-reply-to » @lyse what’s on the one on the left, back? Looks… enticing! 🤤

@bender@twtxt.net That’s the best one of them. An almonds cake with hazelnut chocolate glaze. The one in front is similar, but with chocolate only. Gingerbread on the right. But it develops the best flavor and consistency only in a few weeks, right now it’s quite hard like a rock, but it will soften up.

All those years I always said that my teammates are THE VERY BEST I ever had. Fuck me, look at that, I didn’t leave the company, just changed projects and this is my farewell present: https://lyse.isobeef.org/tmp/abschiedsgeschenk-2025-12-03.jpg How absolutely beautiful is that, I’m in awe! Now I feel even worse deserting. :‘-(

This emblem is the fleur-de-lis of the world scout movement: https://en.wikipedia.org/wiki/World_Organization_of_the_Scout_Movement#WOSM_emblem I reckon I must have mentioned casually that I’m a scout. ;-)

Advent of Code 2025 starts tomorrow. 🥳🎄

This year, I’m going to use Python 1 on SuSE Linux 6.4, writing the code on my trusty old Pentium 133 with its 64 MB of RAM. No idea if that old version of Python will be fast enough for later puzzles. We’ll see.

In-reply-to » Speaking of WAF(s) / Web Applicaiton Firewalls -- I actually had forgotten that not only have I designed a new WAF from scratch, but I've actually implemented it already, and done some local testing. I just haven't put it into production yet... What od you think @aelaraji ? 🤔 https://git.mills.io/prologic/caddy-waf

@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).

AI systems being egregiously resource intensive is not a side effect — it’s the point.

And someone commented on that with:

I’m fascinated by the take about the resource usage being an advantage to the AI bros.

They’ve created software that cannot (practically) be replicated as open source software / free software, because there is no community of people with sufficient hardware / data sets. It will inherently always be a centralized technology.

Fascinating and scary.

In-reply-to » I just noticed this pattern:

And regarding those broken URLs: I once speculated that these bots operate on an old dataset, because I thought that my redirect rules actually were broken once and produced loops. But a) I cannot reproduce this today, and b) I cannot find anything related to that in my Git history, either. But it’s hard to tell, because I switched operating systems and webservers since then …

But the thing is that I’m seeing new URLs constructed in this pattern. So this can’t just be an old crawling dataset.

I am now wondering if those broken URLs are bot bugs as well.

They look like this (zalgo is a new project):

https://www.uninformativ.de/projects/slinp/zalgo/scksums/bevelbar/

When you request that URL, you get redirected to /git/:

$ curl -sI https://www.uninformativ.de/projects/slinp/zalgo/scksums/bevelbar/
HTTP/1.0 301 Moved Permanently
Date: Sat, 22 Nov 2025 06:13:51 GMT
Server: OpenBSD httpd
Connection: close
Content-Type: text/html
Content-Length: 510
Location: /git/

And on /git/, there are links to my repos. So if a broken client requests https://www.uninformativ.de/projects/slinp/zalgo/scksums/bevelbar/, then sees a bunch of links and simply appends them, you’ll end up with an infinite loop.

Is that what’s going on here or are my redirects actually still broken … ?

In-reply-to » My goodness, a new level of stupidity.

I just noticed this pattern:

uninformativ.de 201.218.xxx.xxx - - [22/Nov/2025:06:53:27 +0100] "GET /projects/lariza/multipass/xiate/padme/gophcatch HTTP/1.1" 301 0 "" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/112.0.0.0 Safari/537.36"
www.uninformativ.de 103.10.xxx.xxx  - - [22/Nov/2025:06:53:28 +0100] "GET http://uninformativ.de/projects/lariza/multipass/xiate/padme/gophcatch HTTP/1.1" 400 0 "" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/112.0.0.0 Safari/537.36"

Let me add some spaces to make it more clear:

    uninformativ.de 201.218.xxx.xxx - - [22/Nov/2025:06:53:27 +0100] "GET                       /projects/lariza/multipass/xiate/padme/gophcatch HTTP/1.1" 301 0 "" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/112.0.0.0 Safari/537.36"

Some IP (from Brazil) requests some (non-existing, completely broken) URL from my webserver. But they use the hostname uninformativ.de, so they get redirected to www.uninformativ.de.

In the next step, just a second later, some other IP (from Nepal) issues an HTTP proxy request for the same URL.

Clearly, someone has no idea how HTTP redirects work. And clearly, they’re running their broken code on some kind of botnet all over the world.

I had no meetings this arvo, so I made an appointment with the woods in my extended lunch break. The 6°C warm sun was out all day long and there was only a very light breeze. So, a very nice autumn day.

When I stopped to take a photo in the forest, a deer behind me took off into the woodland. I didn’t see it before. Also, I came across one or the other clearing. Sadly, it’s all commercial timberland here. Luckily, in a year or so, when nature slowly took over and reclaimed some spots, the apocalyptic sites are then looking a bit more decent again.

Cleaning of the ruin walls on my backyard mountain slowly takes shape. They made some progress and moved on to the other section. The flag on top is halfway disintegrated again, all the yellow half is completely gone. I’m wondering if they just stop replacing it at some point in time. But probably not.

Enjoy! https://lyse.isobeef.org/waldspaziergang-2025-11-19/

To everyone previously asking, what my (and other developers) endless complaining about Google, to both every EU body, with a form on their website and every relevant team at Google accomplished…
WE FUCKING WON!!!
“While security is crucial, we’ve also heard from developers and power users who have a higher risk tolerance and want the ability to download unverified apps.”
-source

I was also able to work with my new webhost, to bring back “🐕.fr.to” - everyones favorite vanity redirect domain, for my site, Googles changes to SSL warnings in Chrome, killed at the beginning of this year.

The lesson: I NEED TO COMPLAIN MORE

In-reply-to » There are no really good GUI toolkits for Linux, are there?

@prologic@twtxt.net Hm, same startup delay. (Go is not an option for me anyway.)

It’s hard to tell why all this is so slow. Maybe in this particular case it has something to do with fonts: strace shows the program loading the fontconfig configs several times, and that takes up a bulk of the startup time. 🤔 (Qt6 or Java don’t do that, but they’re still slow to start up – for other reasons, apparently.)

To be fair, it’s “just” the initial program startup (with warm I/O caches). Once it’s running, it’s fine. All toolkits I’ve tried are. But I don’t want to accept such delays, not in the year 2025. 😅 Imagine every terminal window needing half a second to appear on the screen … nah, man.

Thank you for https://www.uninformativ.de/blog/postings/2025-11-09/0/POSTING-en.html, @movq@www.uninformativ.de! I never configured systemd timers, but I would have gotten it wrong, too. Good to know when I eventually stumble across that in the future. I’m still using cron. Yeah, its field order sucks and I always have to look it up (because I don’t deal with that all that often). Indeed, systemd’s order sounds more reasonable.

@movq@www.uninformativ.de this I find more worrisome, and saw no mention of it on your text: Right-Wing Chatbots Turbocharge America’s Political and Cultural Wars (gift article).

Enoch, one of the newer chatbots powered by artificial intelligence, promises “to ‘mind wipe’ the pro-pharma bias” from its answers. Another, Arya, produces content based on instructions that tell it to be an “unapologetic right-wing nationalist Christian A.I. model.”
