The editor can launch a new shell now:

Trivial to implement but super useful. It allows for simple but meaningful dev cycles: Edit source code, run/test it, back to editor. That’s what I do in the video.

(The Brainfuck program is silly, but I got nothing else at the moment.)

The I/O cache is also getting better. All that back and forth doesn’t hit the disk at all, once cached.

This whole thing is much more fun and interesting when you run it from a real floppy disk. It’s a 5.25” floppy in the video (so it’s actually floppy 😅). Disk seek times can be catastrophic and you don’t notice any of this on modern disks.

@movq@www.uninformativ.de Very cool!
