I clicked around in the kernel section and the other commenters highlighting the simplicity weren't lying. It's beautiful in its simplicity.
Seeing the screenshots I was kind of expecting this was a pre-emptive multi-tasking OS (forgetting what I read in the submission).
Things that thus surprised me on a cursory look:
- noticed krn_main() ends with `while (1);` [1]. I would've expected a "schedule" call or something. I assume there's no real busy loop burning CPU, maybe it's never meant to reach this code?
- I'm reminded of the "bare metal OS" when I see one of the apps call `krn_\*` functions directly [2].
This is great, thanks for releasing your work. Very impressive.
You may get some interest from others in the retrocomputing/permacomputing sphere if you implement an Uxn emulator; it is extremely simple and can run on very limited hardware. https://100r.co/site/uxn.html
Vintage hardware would be a great host for Uxn programs, so I suspect this would generate some excitement.
You’re welcome. You’d probably appreciate its focus on long-term stability; the authors wanted an environment for their software that would ensure code could stay frozen in a working state forever. The only thing that may need updates is the VM, as the host OS and userland will shift over time, but the VM is designed to be exceptionally easy to implement and maintain. That comes at the cost of some capabilities, but they were specifically aiming for simpler software, so it works out.

Heh, the "small virtual machine" was NOT a lie! Is that less than 200 lines? Very nice!
Now I feel like integrating that into various things....
Thank you so much! Somehow I haven't heard about Uxn before, but it seems very cool and I'll definitely look into it.
