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.

RFC: Rust Has Provenance
Provenance is a dynamic property of pointer values. The actual underlying rules that a program must follow, even when using raw pointers and `unsafe`, are written in terms of provenance. Miri (https://github.com/rust-lang/miri) represents provenance as an actual value stored alongside each pointer's address, so it can check for violations of these rules.
Lifetimes are a static approximation of provenance. They are erased after being validated by the borrow checker, and do not exist in Miri or have any impact on what transformations the optimizer may perform. In other words, the provenance rules allow a superset of what the borrow checker allows.

I've incidentally created one of the fastest bounded MPSC queue
Actually, I've done more advanced tests with MIRI (see https://github.com/rust-lang/miri/issues/2920 for example) which allowed me to fix some issues. I've also made the code compatible with loom, but I didn't found the time yet to write and execute loom tests. That's on the TODO-list, and I need to track it with an issue too.

Interested in "secure programming languages", both theory and practice but mostly practice, where do I start?
He is one of the big brains behind Miri, which is a interpreter that runs on the MIR (compiler representation between human code and asm/machine code) and detects undefined behavior. Super useful tool for language safety, pretty interesting on its own.

Formal verification for unsafe code?
I would also run your tests in Miri (https://github.com/rust-lang/miri) to try to cover more bases.

Ouroboros is also unsound
You can run miri and it will tell you if the given run triggered any undefined behavior. It will not analyze it for every possible use of the code, but checking for the presence of this specific issue using it should be fairly simple.

From Stacks to Trees: A new aliasing model for Rust
If you do encounter a piece of code on which TB performs much worse than SB, do submit it as an issue! There was one recently and we massively improved TB performance on this case by improving garbage collection.

My Rust program (Well, game) is leaking memory, 4MB/s.
Have you tried adding miri checks to see specific warnings it suggests? It should have some memory leak checks aswell. https://github.com/rust-lang/miri

What would be your programming language of choice to implement a JIT compiler ?
Depends on what you mean by "better experience". What the article doesn't mention is the fact that you can still run into undefined behavior (including pointer aliasing) in C/C++/Zig and have your programs exhibit unexplainable weirdness, but you won't get any help from the language/compiler to figure out where it's coming from. In Rust you just run MIRI which tells you exactly where you have undefined behavior as long as you have at least one test which exercises the affected code path.

RustPython
Contribution graph seems pretty good https://github.com/RustPython/RustPython/graphs/contributors
No.
…and this one is no exception -> https://github.com/RustPython/RustPython/issues/1940
Packages that rely on c dependencies like numpy, etc. only work if you write a custom implementation by hand; the “normal” package flat out doesn’t (and cannot) work.
I first read about RustPython today and found this discussion that seems very interesting and still pertinent to the topic. Here's my take on it:
-
Rewrite Sympy in rust
If you absolutely need something comparable to Sympy, then one option might be to figure out how to best call Sympy from Rust. e.g. - RustPython, although it seems like Sympy isn't supported yet - Pyodide, and figuring out how to run it outside of a web browser. Probably also not very easy. - PyPy, and having a pretty simple Python binary for every platform - ...

Our Plan for Python 3.13
I'm actually rooting for RustPython to reach a level of maturity that we'd just be able to ship apis and stuff with it.... https://github.com/RustPython/RustPython

Python 11
Good question and it also actual for: python 3.12, RustPython and xonsh binary.
