(#zs4mzka) @lyse@lyse.isobeef.org Ooh, lovely! 🌇

I’m drowning the noise with this: https://www.youtube.com/watch?v=tgivYC2s6hs 😅

(#5pjhgha) @lyse@lyse.isobeef.org You actually have a Markdown parser/renderer in there? Oh dear. I would have been (well, I am) way too lazy for that. 😅

(#fdx5m6a) @prologic@twtxt.net Happy New Year 🥳🎆

Why have these Unicode smilies never caught on, I wonder? 🤪

(#2p27wba) The baseline here is about 55 ms for nothing, btw. Python ain’t fast to start up.

$ time python -c 'exit(0)'

real    0m0.055s
user    0m0.046s
sys     0m0.007s

I assume you made the thing load quickly, didn’t you?

That’s the problem with Python. If you have a couple of files to import, it will take time.

I want this to be reasonably fast on my old Intel NUC from 2016 (Celeron N3050 @ 1.60GHz) and I already notice that the program startup takes about 95 ms (or 125 ms when there are no .pyc files yet). That’s still fine, but it shows that I’ll have to be careful and keep this thing very small …

Python 3.14 will bring lazy imports, maybe that can help in some cases.

(#yiihgta) @prologic@twtxt.net No, that’s Python/curses on Linux. 😅

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

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 “ä” 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.)

(#xwn45gq) @lyse@lyse.isobeef.org Well, I used SnipMate years ago (until 2012). IIRC, it’s more than just “insert a bit of text here”, it can also jump to the correct next location(s) and stuff like that. Don’t remember why I stopped using it.

Then I used nothing for a long time. Just before Christmas, I made my own plugin (… of course …), which does everything I need at the moment (and nothing more).

It can insert simple templates and then jump to the next location:

https://movq.de/v/67cdf7c827/sisni%2Dpython.mp4

And replace a string after insertion:

https://movq.de/v/67cdf7c827/sisni%2Dheader.mp4

(It’s not public (yet?) and it also uses vim9script, so I guess it wouldn’t work on your system.)

(#tackqqq) @prologic@twtxt.net Debugging this stuff on bare metal hardware (without an underlying OS) is a nightmare. 🤣

(#sd722yq) @lyse@lyse.isobeef.org That sounds useful. 🤔

This was the scariest movie I’ve seen in a long time, jesus. 🤣 https://en.wikipedia.org/wiki/Fall_(2022_film)

(#j5s5khq) @lyse@lyse.isobeef.org I’m toying with the idea of making a widget/window system on top of Python’s ncurses. I’ve never really been happy with the existing ones (like urwid, textual, pytermgui, …). I mean, they’re not horrible, it’s mostly the performance that’s bugging me – I don’t want to wait an entire second for a terminal program to start up.

Not sure if I’ll actually see it through, though. Unicode makes this kind of thing extremely hard. 🫤

(#7tsxwnq) @lyse@lyse.isobeef.org Bwahaha. 🤣

Trying to come up with a name for a new project and every name is already taken. 🤣 The internet is full!

(#kaiqxgq) @prologic@twtxt.net This is a really cool project, that’s for sure. 👌

(#p4hxpnq) @lyse@lyse.isobeef.org … I was about to write “it really is worse where you live”, then I heard the first bang out on the street. 🤣

(#gslvc3q) @prologic@twtxt.net Oh! 🤔

(#gslvc3q) @prologic@twtxt.net That might be a challenge, at least in 16-bit Real Mode: The OS follows the model of COM files on DOS, i.e. the size of the binary cannot exceed 64 KiB and heap+stack of the running program will have to fit into that same 64 KiB. 😅 (The memory layout is very rigid, each process gets such a 64 KiB slice.)

And in 64-bit Long Mode, there is no “kernel” yet. The thing in the video is literally just a small bare-metal program.

But some day, maybe. 😃

(#gslvc3q) Seeing this run on real hardware is so satisfying, even if it’s just a small example. 😅

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.)

(#axubhsq) @prologic@twtxt.net And I froze my ass off yesterday at -5°C and strong winds. 🤣

(#xpo7apa) @prologic@twtxt.net 🎄 Merry Christmas and stuff 😅🎅

(#h2bah2a) @lyse@lyse.isobeef.org Lovely! We also just had some snow. 😃 Not a lot, but still. 😅

(Lol, I totally read that as “rootfs”. 🤪)

(#h2bah2a) @lyse@lyse.isobeef.org Oooh, nice! ⛄ We only have cold stormy weather over here. 🥴

(#jsy4ega) @lyse@lyse.isobeef.org Thanks. 😅 (Do I say that? The WM can’t answer. 🤣)

Mastodon has a “Wrapstodon 2025” now, showing you a “wrap up” of the year. Of course, a pointless funny shitpost was my most “successful” post in 2025. 😂

(#c6rrdzq) @prologic@twtxt.net I’ve been awake at that time, didn’t notice anything. 🤔 Where was that BGP analyzer again … 😅 There’s a tool that keeps track of these things, right? I forgot what it was.

(#c6rrdzq) @prologic@twtxt.net Hm, I didn’t notice anything. Perhaps I was asleep? 😅

(#dddn3ja) @prologic@twtxt.net You write so much code … it’s incredible. 😅
