I have also developed a preemtive-multitasking O/S (and some programming languages to build this and apps) targeted for embedded soft cpu (not x86).

I build tools in Rust, too. I joined your discord but cannot comment anywhere yet (lack of permissions).

Do you use AI coding agents?

Yes. But only for the coding. The rest is still done by me (hardware testing, QEMU, debugging, instructions, ideas, and so on).

I have forked, cloned, and built (had to pin a specific nightly Rust for it to build). When I run it, it crashed at login; I reran it with VNC, was able to login as root, issue ls and uptime, but then it crashed. My AI is debugging...

so the built-in nano helps a lot, since the help output scrolled off the screen. I tried to use head, less, and more. I could redirect help output to a file (but until I found nano, could not page that). I also looked for dd.

The VNC UI seems generally stable, I was able to log in as all three users, and issue many commands.

Is there a bundled assembler or compiler. How can I write apps for this? Do you have a way to cross-compile and mount a shared folder or scp binaries in?

My AI wrote scripts to launch and attach. I was able to do a lot login in as root. One bug: when I run the ring3 demo, the shell stops accepting input.

And by the way, I think I've fixed the Discord issue. Try testing it when you can.

In one of his interviews, Linus suggested that next-gen OS would be written in Rust. You picked an interesting track, starred your repo!
