gopher-os VS biscuit

But there are other brave people exists like biscuit or gopher-os who can do it :)))

Can it? Yes. Should it? Now that’s up for debate.

golang? https://github.com/gopher-os/gopher-os

I'm sure it would be a fun proof of concept, and there seem to be some projects like https://github.com/gopher-os/gopher-os , but they themselves admit it's just a proof of concept. Every tool has its use.

I’m pretty the C in the the OS is just the libc that is used for user programs and not part of the actual kernel. There is also gopherOS which contains no C at all. My only point was that it is possible to write one in Go and that Go can be used for low level coding. And I don’t believe you can write an OS in pure python bc it isn’t compiled

Wait. You're not who we asked for

No, it isn't the third release of a POSIX like OS research written in Go,

That's something I found in doing a bit of a dive on why ripgrep is so fast at doing a very specific kind of string search workload (Gallant / burntsushi / author of ripgrep is an actual wizard and contributes to Rust's regex engines, for reference). I wrote tiny proof of concepts in a variety of languages, all in my same style -- and sometimes my Go variants were as fast as the equivalent Rust/C (even in release / -O3/2 (every once in a blue moon, O3 makes no diff or is a slight regression in some exec paths)). I eventually found something about benchmarks in a related area, leading to this: https://benhoyt.com/writings/count-words/#performance-results-and-learnings. Somebody on the Go sub even linked me to the Biscuit OS: https://pdos.csail.mit.edu/papers/biscuit.pdf, which, tidbit, has Jon Gjengset (Crust of Rust legend) in the contribs list (https://github.com/mit-pdos/biscuit).

Go has been used to implement OS kernel code, e.g. in the Biscuit OS from MIT: https://github.com/mit-pdos/biscuit

Of course, the garbage collector did not exactly make it easier - but it's an interesting piece of software.

https://github.com/mit-pdos/biscuit says 5% slowdown over C. Garbage collection is going to require some more RAM, generally <=2x though.
