Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Biscuit 3.0
No, it isn't the third release of a POSIX like OS research written in Go,

If I know neither Go or Rust, which do I choose to learn first/only?
But there are other brave people exists like biscuit or gopher-os who can do it :)))

Pre-Overengineering
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).

Rust: A Critical Retrospective
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.

FreeBSD evaluating Rust's adoption into base system
There is a Rust front-end for GCC that is under active development [1]. If the chip vendors are not willing to develop and upstream a LLVM back-end then they can feel free to start contributing to it.

Why do lifetimes need to be leaky?
That's why gccrs doesn't even consider lifetime checking a part of the language (they plan to use Polonius, too).

How hard would it be to port the Rust toolchain to a new non-POSIX OS written in Rust and get it to host its own development? What would that process entail?
There's ongoing work on a Rust front-end for GCC (https://github.com/Rust-GCC/gccrs). Bit barebones right now -- ie, even core doesn't compile -- but there's funding, demand, and regular progress, so it'll only get better from there. Once gccrs can compile core, it should be ready to compile most of Rust, and thus if you've taught the calling conventions for C to GCC, you're golden.
-
How hard is it to write a front end for a more complex language like Rust or Kotlin?
I recommend checking out the GCC Rust frontend project.

Rust contributions for Linux 6.4 are finally merged upstream!
That is what theyre refering to, yes. The GitHub is named https://github.com/Rust-GCC/gccrs

GCC 13 and the State of Gccrs
- But this misses so much extra context information
3. Macro invocations there are really subtle rules on how you treat macro invocations such as this which is not documented at all https://github.com/Rust-GCC/gccrs/blob/master/gcc/rust/expan...
Some day I personally want to write a blog post about how complicated and under spec'd Rust is, then write one about the stuff i do like it such as iterators being part of libcore so i don't need reactive extensions.

Any alternate Rust compilers?
(Speaking of which, Rust-GCC (or gcc-rs or gccrs or whichever other of their names they decide is the primary one) isn't even going to be a complete C++ implementation. Their plan is to implement enough to compile Polonius (the NLL 2.0 borrow checker being developed in Rust for rustc) and then share that since borrow-checking isn't necessary for codegen... only to identify and reject invalid programs... making the C++ portion of it not that different in scope from mrustc.)
-
Which programming languages, if all legacy code written in them was ported to a more modern language, would become extinct?
That bridge will be crossed with gccrs (compiling Rust with gcc directly, coming next month with GCC 13) and rust_codegen_gcc (rustc frontend, GCC backend, works now but just doesn’t yet have an “easy” setup)
What are some alternatives?
Cosmos - Cosmos is an operating system "construction kit". Build your own OS using managed languages such as C#, VB.NET, and more!
gcc-rust - a (WIP) Rust frontend for gcc / a gcc backend for rustc
regex-automata - A low level regular expression library that uses deterministic finite automata.
rustc_codegen_gcc - libgccjit AOT codegen for rustc
TinyGo - Go compiler for small places. Microcontrollers, WebAssembly (WASM/WASI), and command-line tools. Based on LLVM.
rustc_codegen_gcc - libgccjit AOT codegen for rustc
Harbol - Harbol is a collection of data structures and miscellaneous libraries, similar in nature to C++'s Boost, STL, and GNOME's GLib; it is meant to be a smaller and more lightweight collection of data structures, code systems, and convenience software.
