Well, you girls and guys are making cool things, and I have some progress to show as well. 😅

https://movq.de/v/c0408a80b1/movwin.mp4

Scrolling widgets appears to work now. This is (mostly) Unicode-aware: Note how emojis like “😅” are double-width “characters” and the widget system knows this. It doesn’t try to place a “😅” in a location where there’s only one cell available.

Same goes for that weird â€œĂ€â€ thingie, which is actually “a” followed by U+0308 (a combining diacritic). Python itself thinks of this as two “characters”, but they only occupy one cell on the screen. (Assuming your terminal supports this 
)

This library does the heavy Unicode lifting: https://github.com/jquast/wcwidth (Take a look at its implementation to learn how horrible Unicode and human languages are.)

The program itself looks like this, it’s a proper widget hierarchy:

(There is no input handling yet, hence some things are hardwired for the moment.)

In-reply-to » 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).

@movq@www.uninformativ.de It’d be cool if you could get ” (Mu) running in your little toyOS đŸ€Ł You’d technically only have to swap out the syscall() builtin for whatever your toy OS supports đŸ€”

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. đŸ€Ż 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.

All I needed was one of those slot-cable-thingies. (And if the order of pins is correct, then it actually works. đŸ€Š)

The https://pyscript.com “platform” for hosting/serving and sharing #pyscript projects seems very cool
 I wish they had a “download project” button to make it easy to move your project elsewhere. As they seem to be moving towards some “paid tier features”, making it easy to take everything out would be nice, would feel less like putting on a risk of being inadvertently locked in.

https://fokus.cool/2025/11/25/i-dont-care-how-well-your-ai-works.html

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.

Design trends I think will take off in 2026
but tierlist

S - move from flat design to more detailed, 3D, more complex logos.

A - glass, not just liquid, Windows Vista, 7, 11,
 accessibility concerns, but I like to see it.

B-/C+ - black and white icons, favicons. I did it before it was cool, but it’s getting overused.

E - gradientslop, barely started, already all blends together.

It’s time to say goodbye to the GTK world.

GTK2 was nice to work with, relatively lightweight, and there were many cool themes back then. GTK3 was already a bit clunky, but tolerable. GTK4 now pulls in all kinds of stuff that I’m not interested in, it has become quite heavy.

Farewell. 👋

All good things come to an end, I guess.

I have an Epson printer (AcuLaser C1100) and an Epson scanner (Perfection V10), both of which I bought about 20 years ago. The hardware still works perfectly fine.

Until recently, Epson still provided Linux drivers for them. That is pretty cool! I noticed today that they have relaunched their driver website – and now I can’t find any Linux drivers for that hardware anymore. Just doesn’t list it (it does list some drivers for Windows 7, for example).

I mean, okay, we’re talking about 20 years here. That is a very long time, much more than I expected. But if it still works, why not keep using it?

Some years ago, I started archiving these drivers locally, because I anticipated that they might vanish at some point. So I can still use my hardware for now (even if I had to reinstall my PC for some reason). It might get hacky at some point in the future, though.

This once more underlines the importance of FOSS drivers for your hardware. I sadly didn’t pay attention to that 20 years ago.

Hello everyone! 👋

After a long while away, I’m back on twtxt with this new feed.

Some of you might remember me as justamoment@twtxt.net, that was a test account I made for trying things out, but I ended up keeping it more than planned.

I also tried other social platforms in search of a place that felt right for me.

In the end twtxt was the one that ticked all of my boxes:

  • Slow social: it act more like a feed reader and I really appreciate that there’s no flood of content that I can’t keep up with.
  • No server needed: I absolutely love to have total control over my content, I tend to avoid having moving parts that might break, plus you can put your feed under version control and it’s all backed up.
  • Ownership: I can put my feed anywhere I want and nobody can decide if I can access it or not.
  • For hackers: a single .txt file allows me to join a community, how cool is that!

This is why I decided to build my own twtxt client, one that allows you to decide how the feed is presented on your “instance”.

It’s still in the making but I’ll try to share a bit of it once I defined how things should work.

Coincidentally, I discovered that @itsericwoodward@itsericwoodward.com and @zvava@twtxt.net were also building a twtxt client, seems like twtxt is set to grow!

In-reply-to » Good morning. Driving the dot matrix printer from my little real-mode toy OS. đŸ–šïž

@lyse@lyse.isobeef.org @dce@hashnix.club It’s pretty cool, I won’t argue that, but also really simple, to be completely honest. 😅 The BIOS already provides all you need to send data to the printer:

https://helppc.netcore2k.net/interrupt/bios-printer-services

The BIOS actually does provide a great deal of things, which, to me, was one of the most surprising learnings of this project (the project of writing a little 16-bit real-mode OS, that is). It often doesn’t feel like I was writing an operating system – it felt more like writing a normal program that just uses BIOS calls like we would use syscalls these days.

(I’ve also read a lot of warnings, like “don’t use the BIOS for this or that”. Mostly because it tends to be very slow.)

I never used hardcopy terminals, either. We did have a dotmatrix printer, but that was just used as a regular printer.

Inkjets, I don’t know. They were pretty fascinating and cool when they came out. A lot faster than dotmatrix and obviously quiter. They never gave me much trouble, actually. But I switched to a laser printer long before crap like DRM’ed ink cartridges became a thing.

In-reply-to » Speaking of manpages:

@kat@yarn.girlonthemoon.xyz On the one hand, all these programs have a very long history and the technology behind manpages is actually very powerful – you can use it to write books:

https://www.troff.org/pubs.html

I have two books from that list, for example “The UNIX programming environment”:

https://movq.de/v/c3dab75c97/upe.jpg

It’s a bit older, of course, but it looks and feels like a normal book, and it uses the same tech as manpages – which I think is really cool. 😎

It’s comparable to LaTeX (just harder/different to use) but much faster than LaTeX. You can also do stuff like render manpages as a PDF (man -Tpdf cp >cp.pdf) or as an HTML file (man -Thtml cp >cp.html). I think I once made slides for a talk this way.

On the other hand, traditional manpages (i.e., ones that are not written in mandoc) do not use semantic markup. They literally say, “this text is bold, that text over here is italics”, and so on.

So when you run man foo, it has no other choice but to show it in black, white, bold, underline – showing it in color would be wrong, because that’s not what the source code of that manpage says.

Colorizing them is a hack, to be honest. You’re not meant to do this. (The devs actually broke this by accident recently. They themselves aren’t really aware that people use colors.)

If mandoc and semantic markup was more commonly used, I think it would be easier to convince the devs to add proper customizable colors.

In-reply-to » OH, FUCK ME DEAD! On the way home from today's walk I saw easily 800 fireflies! Yes, over eight hundred! That was absolutely amazing. First time this year and already this many. Crazy! They were just fricking everywhere in the entire forest. I counted to one hundred and then stopped. The darker it got, the more fireflies came out and glowed around. :-) There were spots where in under ten seconds I counted 20 glowworms. Super sick. Soooo beautiful. <3

I didn’t manage to leave the house yesterday. But when I went into the woods this evening, activity first was 10% of what it had been the day before yesterday. By the end it got a lot busier, about 50% of last time I reckon. Around 500 fireflies I’d imagine. I might have been faster than the days before. When I left the forest, I was right in the fog, that was cool.

Shortly after, I saw another lightshow. Right behind the Wasserberghaus somewhere on the Swabian Alp there was very crazy heat lightning every 5-10 seconds. That looked absolutely amazing. :-)

I did a “lecture”/“workshop” about this at work today. 16-bit DOS, real mode. đŸ’Ÿ Pretty cool and the audience (devs and sysadmins) seemed quite interested. đŸ„ł

  • People used the Intel docs to figure out the instruction encodings.
  • Then they wrote a little DOS program that exits with a return code and they used uhex in DOSBox to do that. Yes, we wrote a COM file manually, no Assembler involved. (Many of them had never used DOS before.)
  • DEBUG from FreeDOS was used to single-step through the program, showing what it does.
  • This gets tedious rather quickly, so we switched to SVED from SvarDOS for writing the rest of the program in Assembly language. nasm worked great for us.
  • At the end, we switched to BIOS calls instead of DOS syscalls to demonstrate that the same binary COM file works on another OS. Also a good opportunity to talk about bootloaders a little bit.
  • (I think they even understood the basics of segmentation in the end.)

The 8086 / 16-bit real-mode DOS is a great platform to explain a lot of the fundamentals without having to deal with OS semantics or executable file formats.

Now that was a lot of fun. đŸ„ł It’s very rare that we do something like this, sadly. I love doing this kind of low-level stuff.

Once again, I went on a hike onto my backyard mountain after calling it quits very late. This time I brought my cam along. The view was extremely hazy, but the setting sunlight resulted in cool colors. The freshly cut grass smelled wonderful.

I saw a flock of pidgeons circling around and some sort of rat or mouse quickly running over the road in front of me from one field into the next one with a giant nut in its mouth. Or so I at least believe, couldn’t really tell, it happened so fast.

A couple enjoyed the setting sun on a bench and stripped their shoes on this warm evening. Somebody forget their bottle of water on the summit, but it looked rather cool in the evening light:
