2024 was a funny year: The year begins and ends with calendar week 1:

The one in January being 2024-W01 and the one in December 2025-W01.

🤓

(Hmmm, my printed LaTeX calendar using tikz-kalender gets it wrong or uses different week definitions. It shows next week as 53. 🤔)

@movq@www.uninformativ.de Oh, a movqOS, that’s super cool! :-)

Yeah, glossy screens are straight from hell. :-D What’s this spooky wind chime background music?

Anyway, have great fun learning more and experimenting with this low level stuff!

I’ve been making a little toy operating system for the 8086 in the last few days. Now that was a lot of fun!

I don’t plan on making that code public. This is purely a learning project for myself. I think going for real-mode 8086 + BIOS is a good idea as a first step. I am well aware that this isn’t going anywhere – but now I’ve gained some experience and learned a ton of stuff, so maybe 32 bit or even 64 bit mode might be doable in the future? We’ll see.

It provides a syscall interface, can launch processes, read/write files (in a very simple filesystem).

Here’s a video where I run it natively on my old Dell Inspiron 6400 laptop (and Warp 3 later in the video, because why not):

(Sorry for the skewed video. It’s a glossy display and super hard to film this.)

It starts with the laptop’s boot menu and then boots into the kernel and launches a shell as PID 1. From there, I can launch other processes (anything I enter is a new process, except for the exit at the end) and they return the shell afterwards.

And a screenshot running in QEMU:

In-reply-to » As long as you can correctly statically link your binary of course 🤣

@prologic@twtxt.net I’m scratching my head already trying to figure this one out 🤣 not sure if just mirroring ldd’s output into my image’s content would do, -I’ve Just found about that one by the way.- but I’ll never know until I try.

In-reply-to » @bender I built my own, a much smaller one with a multi stage build... shouldn't that do the trick? 🤔

@bender@twtxt.net Dud! you should see the updated version! 😂 I have just discovered the scratch #container image and decided I wanted to play with it… I’m probably going to end up rebuilding a LOT of images.

In-reply-to » For Example:

@prologic@twtxt.net maybe you meant to specify twtxt as a type similar to ActivityPub’s application/activity+json in https://webfinger.net/lookup/?resource=sorenpeter@norrebro.space

    {
      "rel": "self",
      "type": "application/activity+json",
      "href": "https://norrebro.space/users/sorenpeter"
    },

Then it would also make sense to define a Link Relations but should that then link to something like https://twtxt.dev/webfinger.html where we can describe the spec?
