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.

Why do lifetimes need to be leaky?
Correctness prover which uses lifetimes (Polonius).
-
Databases are the endgame for data-oriented design
And, well, polonius (Rust borrow checker magic) I believe is built on datalog-ish concepts: https://github.com/rust-lang/polonius
-
Why doesn't rust-analyzer reuse infrastructures of rustc?
There is also polonius (https://github.com/rust-lang/polonius) which should replace the borrow checker but does not receive a lot of development resources.
-
Rust front-end merged in GCC trunk
This is eventually going to be a feature-complete compiler, targeting a specific rustc version. I believe the plan is to use polonius [1], presumably as an "optional" feature so they can build a stage 1 without it, use that to build polonius, then build the final compiler with it included.

Blog post: Rust in 2023
E.g. there you may just stop using current borrow-checker and switch to Polonius.
-
What are Rust’s biggest weaknesses?
The borrow checker is too dumb (https://github.com/rust-lang/polonius) fixes a lot of this.
-
Datafrog: A lightweight Datalog engine in Rust
It looks like an official borrow checker implementation called Polonius uses it as a dependency, so it makes sense: https://github.com/rust-lang/polonius/blob/981785c101b68ff54...
-
Differential Datalog: a programming language for incremental computation
If you click around a little, you end up on a blog post with this tidbit:
> This project got put together rather suddenly, in response to some work the Rust folks are doing[1] on their new and improved borrow checker.
I don't think I could tell you more than "Frank wrote it to help rust folks who were previously doing work with differential-dataflow directly."

Generic associated types to be stable in Rust 1.65
Good news is that there's also works going on to relax the restrictions, like polonius. But it seems that it still have a long way to go before it can land in stable Rust...
-
Rust for Linux officially merged
GCC-rs isn't intended for bootstrapping, it is intended to be an actual fully featured Rust compiler in the future, mrustc is a Rust compiler intended for bootstrapping though. GCC-rs is still very early targeting an older version of the reference compiler without things like a borrow checker, but that's not going to be the case forever. The GCC-rs folks have expressed interest in re-using the borrow checker library used by the reference compiler called polonius enabling them to relatively easily add borrow checking.

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?
