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.

Show HN: Regex Derivatives (Brzozowski Derivatives)
I don't think Rust regex engine relies on this technique. I guess the main point is when you construct the DFA directly you still have the possibility of the exponential explosion of the number of states. That's why modern engines balance between NFA/DFA and lazy DFA.
Though there is an implementation that relies only on Brzozowski derivatives: https://github.com/google/redgrep

Introducing: Pomsky (formerly Rulex)
redgrep did it though: https://github.com/google/redgrep
- Redgrep – grep based on regex derivatives, matches in linear time

Speed of Rust vs. C
It couldn't figure it out from looking through ripgrep's website: does ripgrep support intersection and complement of expressions? Like eg https://github.com/google/redgrep does.
Regular languages are closed under those operations after all.

GCC Rust Monthly Report #9 August 2021
It's true that if this project succeeds, that would be an outcome, but it's probably worth noting that you'd really only have to add support for the GCC backend to do that, and not reimplement the frontend as well (parsing, type checking, lifetime checking, etc.). There's an unrelated project working to do that: https://github.com/antoyo/rustc_codegen_gcc that would likely yield those same benefits for less effort.

platform support (may improve soon)

Recursive fib is faster in C++?
Here's the gcc backend for rustc here https://github.com/antoyo/rustc_codegen_gcc Since this just swaps the optimizer/codegen module and reuses all the other stuff from rustc it needs less work and can already compile many valid rust programs.
-
Anyone used the gcc backend before?
I'd like to use the rustc_codegen_gcc backend to compile some Rust programs, but I'm confused about how to install and use the patched libgccjit dependency. I've downloaded the fork provided but don't know where to go from there.

The Tor Project announces Arti, a Tor implementation written in Rust from scratch
I was being a little sloppy and mixing together "actual embedded hardware" with "extensions for applications written in other languages" in my head. I think your point about LLVM is still accurate, though I hear peeps about different projects working on GCC support from time to time.
-
Rust GCC back end was officially accepted into the compiler
This doesn't have anything to do with using GCC to compile rust, but instead using rustc to compile Rust using the GCC backend. You can do that today by using the linked project, rustc_codegen_gcc, which is intended to be integrated into rustc at some point in the (hopefully near) future.
-
This is the patch series to add support for Rust as a second language to the Linux kernel.
Rather than mrustc you should probably look at rustc_codegen_gcc which uses gcc as a backend to rustc (WIP) or GCC Rust which tries to implement a rust frontend for gcc (also WIP). I think rustc_codegen_gcc looks the most promising at the moment
