From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

This isn't Linux, but Linux-like. Its a microkernel built from the rust programming language. Its still experimental, but I think it has great potential. It has a GUI desktop, but the compiler isn't quite fully working yet.

Has anyone used this before? What was your experience with it?

Note: If this is inappropriate since this isn't technically Linux, mods please take down.

(notice: I am not a Rust or C/C++ expert)

Doing all that is creating a completely separate programming language from C. Rust is that programming language.

Fix shitty imports

Rust does that with modules and crates.

Improve syntax rule

You mean having consistent/universal style guidelines? Rust pretty much has that with rustfmt.

Improve memory management

Safe Rust is memory safe (using things like the borrow checker), and Unsafe Rust is (usually?) separated using the unsafe keyword.

Although Unsafe Rust seems to be quite a mess, idk haven't tried it

Other new misc features

Rust has macros, iterators, lambdas, etc. C doesn't have those. C++ probably has those but in a really weird C++ way.

I'd say no. Programming safely requires non-trivial transformation in code and a radical change in style, which afaik cannot be easily done automated.

Do you think that there's any chance to convert from this to this? It requires understanding of the algorithm and a thorough rewrite. Automated tools can only generate the former one because it must not change C's crooked semantics.
