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.

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.

Unsafe Rust
You can also use Kani to check unsafe code. https://github.com/model-checking/kani

Kani 0.28.0 has been released!
Here's a summary of what's new in version 0.28.0:
-
Kani 0.27.0 has been released!
However, there may be more down the line since we don't have (1) for now. If you're interested, would you mind commenting to this issue?
We're excited to announce the release of Kani Rust Verifier v0.27.0! Kani is a bit-precise model checker for Rust, and this new release comes with exciting changes and improvements.

- 5 Alternatives to Redux for React State Management
-
Get out of state management hell with automatic revalidation
You add the current user state to a React Context or state management library, read from it on the top bar, and write to it after a user signs in. Done. No big deal, right?

Scalability: the Lost Level of React State Management
Lastly, I know that I've omitted many great tools like XState, React Query, and SWR. These tools are utilities that are very scalable in their own right, but aren't full replacements for a good state manager.

JavaScript State Machines and Statecharts
There's also a pared down, minimal version of xstate: https://github.com/statelyai/xstate/tree/main/packages/xstat...

Is redux and thunks still used or are there other alternatives for it now?
XState is different, but very good when you need state machines

Developers should be force-fed state machines (2011)
> But I rarely see mention of messier problems which consist of overlapping and perhaps hierarchical states.
That's what State Charts were designed for: https://www.inf.ed.ac.uk/teaching/courses/seoc/2005_2006/res...
It's used as the basis for a number of state machine / state chart libraries, for instance XState: https://xstate.js.org/docs/
