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/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.)

Happy birthday Katrina! https://www.uninformativ.de/blog/postings/2025-12-23/0/POSTING-en.html :-)

Wow, @movq@www.uninformativ.de, 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

I quit LinkedIn
I recently quit LinkedIn. Ironically, the post I made about why I was
quitting was probably the most viewed thing I ever posted. Haha.

If you need to see my CV it’s right here on my website:

https://hack.org/~mc/cv.html

This is what I wrote back in November:

I’m terminating my account on LinkedIn next week. This is possibly
some kind of career suicide.

I’m very seldom visiting LinkedIn, so I’m probably late to the party,
as usual. Perhaps there has already been a lar … ⌘ Read more

The phone situation
I need to write something about this or I’ll burst.

I have a new phone. It’s an old iPhone SE 2022. Yes, I know. Evil,
evil Apple. Won’t someone please think of the privacy issues? Right,
well, Apple has at least better reputation about these things than
Google does, but we’ll come to that.

It feels like I’m betraying the FLOSS cause. I feel horrible, although
probably not just because of this.

Let’s recap:

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. 🤣

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.

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.

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 … ?

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.”

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
