A noble idea, but Github is literally littered with hobbyist home-grown Unix-like kernels in C. As an industry are we not supposed to be trying to move away from hoary old unsafe C? Could we not have a hobbyist educational OSes in more of the C replacements? Drew DeVault wrote Bunnix in Hare, in one month. There's the proof of concept. How about tiny toy Unix-likes in Zig, Nim, Crystal, Odin, D, Rust, Circle, Carbon, Austral? How about ones that aren't ostensibly suitable for such tasks, such as Go or Ada? Yes I know Ada is not a good fit, but there has already been a Unix-like OS entirely implemented in a derivative of Pascal: TUNIS. https://en.wikipedia.org/wiki/TUNIS This might need work from skilled expert practitioners first. That's good. That's what experts are for: teaching, and uplifting newbies. There was a project to do C# on th

e bare metal. https://migeel.sk/blog/2023/12/08/building-bare-metal-bootab... How about a Unix-like in C#? Get the Unix and .NET folks interested in this stuff. Even if the OS never leads to anything, maybe the tooling might prove useful. I am sure someone somewhere would have uses for bare-metal GoLang. Saying that, I really don't think we need any more Unix-like OSes. There are far far too many of those already. There is a huge problem space to be explored here, and there used to be fascinating OSes that did things no Unix-like ever did. OSes that are by modern standards tiny and simple but explored interesting areas of OS design, and are FOSS, with code out there under permissive licenses: * Plan 9 https://github.com/plan9foundation/plan9 * Inferno https://github.com/inferno-os/inferno-os * Symbian https://github.com/SymbianSource * Parhelion HeliOS https://archive.org/details/Heliosukernel There is already an effort at Plan 9 in Rust: https://github.com/dancrossnyc/r9 Why not Plan 9 in Zig, or Hare, or even D? Plan 9 imposes and enforces considerably more simplicity on C as it is: you can't #include stuff that already has #include statements of its own. The result is a compilation speedup of around 3 orders of magnitude. That would be a benefit to the would-be C replacements too, wouldn't it?
In Operating System in 1,000 Lines – Intro
Debatable: 80 columns ease reading, as each line is completely within the cone of vision. It's not enforced in their style(5)[0], but the code mostly and naturally (e.g. short variable names) falls within this limit (random sample[1]). (I don't think that Plan9's "not thinking in terms of terminals", which is more of a "a better-than-X11 GUI is the default UI" is really relevant in this context) EDIT: I don't have a Plan9 box around, but at least on plan9port, man(1) by default wraps lines to 72 columns or so.
