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.

Re-fixing Servo's event-loop
There's a model checker that can directly verify Rust code, Kani https://model-checking.github.io/kani/ - I wonder if Servo could use it in this case?

The Wizardry Frontier
Nice read! Rust has pushed, and will continue to push, the limits of practical, bare metal, memory safe languages. And it's interesting to think about what's next, maybe eventually there will be some form of practical theorem proving "for the masses". Lean 4 looks great and has potential, but it's still mostly a language for mathematicians. There has been some research on AI constructed proofs, which could be the best of both worlds because then the type checker can verify that the AI generated code/proof is indeed correct. Tools like Kani are also a step forward in program correctness.

CVE-2023-4863: Heap buffer overflow in WebP (Chrome)
> those applications need the proof for correctness so that more dangerous code---say, what would need `unsafe` in Rust---can be safely added
There are actually already tools built for this very purpose in Rust (see Kani [1] for instance).
Formal verification has a serious scaling problem, so forming programs in such a way that there are a few performance-critical areas that use unsafe routines seems like the best route. I feel like Rust leans into this paradigm with `unsafe` blocks.
