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.

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.

Kani 0.38.0 has been released !
Here's a summary of what's new in version 0.38.0:
-
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.

Kani 0.36.0 has been released!
Enable concrete playback for failure of UB checks by @zhassan-aws in https://github.com/model-checking/kani/pull/2727
-
Kani 0.34.0 has been released!
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.

Kani 0.33.0 has been released!
Add support for sysconf by feliperodri in #2557

Bebop v3: a fast, modern replacement to Protocol Buffers
This is awesome. I'd love to have upstream support in Wasmer ( https://wasmer.io )

Unlocking the Power of WebAssembly
WebAssembly is extremely portable. WebAssembly runs on: all major web browsers, V8 runtimes like Node.js, and independent Wasm runtimes like Wasmtime, Lucet, and Wasmer.

Show HN: dockerc โ Docker image to static executable "compiler"
Unfortunately cosmopolitan wouldn't work for dockerc. Cosmopolitan works as long as you only use it but container runtimes require additional features. Also containers contain arbitrary executables so not sure how that would work either...
As for WASM, this is already possible using container2wasm[0] and wasmer[1]'s ability to generate static binaries.

Howto: WASM runtimes in Docker / Colima
I could not find any guide how to add WASM container capability to Docker running on Colima. This guide provides a few Colima templates for exactly this, which adds WasmEdge, Wasmtime and Wasmer runtime types.

Show HN: Mutable.ai โ Turn your codebase into a Wiki
Just suggested as well Wasmer on Twitter! https://github.com/wasmerio/wasmer
Looking forward to seeing the results :)

Prettier $20k Bounty was Claimed
The Biome team has been incredibly fast on solving the challenge and achieving 95% compatibility with Prettier [1]
Just as a note, as it was not mentioned in the article, Wasmer [2] also participated with a $2,500 bounty to compile Biome to WASIX [3], and it has been awesome to see how their team has been working to achieve this as well... hopefully we'll get Biome running in Wasmer soon!
Keep up the great work!!

The Curse of Docker
It's funny how WebAssembly can help overcome most of the issues mentioned on the blogpost (packaging, configuration, portability) if addressed properly.
That's the main reason Wasmer [1] was created :)
