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.

Automated reasoning and generative AI: Harness creativity with formal verifications
Modern software verification employs various approaches, each offering different trade-offs between ease of use and strength of guarantees. AWS contributes to the open source program verification tools used in the previous examples. Dafny and Kani represent two powerful approaches to program verification. Let's see how they work in practice before connecting the dots between automated reasoning and generative AI.

Isolating complexity is the essence of successful abstractions
I agree with what you're saying, but some context:
> I'm not aware of one for rust, but there is a lot of progress in this area
https://github.com/model-checking/kani is probably the best known one, I believe there are a few others.
> (I'm not sure what rust allows, particularly in unsafe).
You can't "cast const away" in Rust, even in unsafe. That is, you can do it in unsafe, but it is always undefined behavior to do so. (I am speaking about &T and &mut T here, const T and mut T exist and you're allowed to cast between those, as they have no real aliasing requirements and are really just a lint.)

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.

Rust devs push back as Serde project ships precompiled binaries
The precompiled binary is not a sandboxed WASM binary. Despite the name "watt" it has nothing to do with https://github.com/dtolnay/watt . You can look at the actual code to see for yourself.

* Related: watt is one approach to pre-compile proc-macro crates using WASM.

My first year with Rust: The good, the bad, the ugly
In addition to thiserror and anyhow, our resident superhuman Rust-improving Robot, dtolnay, also developed an experiment in distributing precompiled proc macros as WebAssembly named Watt and, though I never bothered to create a Zulip account so I don't know what was said, I'm told there has been discussion around the idea of implementing something in that vein.

Rust is coming to the Linux kernel
I think when we have Cranelift, Mold, and maybe Watt all working together then compile times will basically be a non-issue. It'll be a few years though.

Check out https://github.com/dtolnay/watt - it's a really interesting solution to the problem!

Backdooring Rust crates for fun and profit
I really like the idea of Watt: https://github.com/dtolnay/watt Run macros in a wasm sandbox so they can't touch anything you don't explicitly allow.

NPM malware and what it could imply for Cargo
I really wish there was more interest in getting something like Watt upstreamed.
