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.

Testing in rust: are there any useful crates, macros etc that you use to make this easier and less verbose?
For that reason I've recently created lets_expect. It's a procedural macro that introduces its own syntax for unit tests inspired by RSpec's one-liner syntax. I think it looks very clean and concise. I consider it experimental at this point, so I haven't announced it anywhere yet, but I use it to test some of my Rust code. Basic structure is as follows:

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.

Change default solver to CaDiCaL by @celinval in https://github.com/model-checking/kani/pull/2557 By default, Kani will now run CBMC with CaDiCaL, since this solver has outperformed Minisat in most of our benchmarks. User's should still be able to select Minisat (or a different solver) either by using #[solver] harness attribute, or by passing --solver= command line option.
