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.

- What feature would you like to see implemented/stabilized?

How do you work with someone else's fork?
They had forked the project we were talking about on Github, and in their local they checked out a branch of their own to work on, done some awesome work, and pushed their branch back to their fork on Github.

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.
