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.

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.

A fast STM32 embedded system emulator implemented in Rust
now integrate gdbstub to support debugging code inside the emulator :)

Noctane: a highly WIP original PlayStation emulator
Shameless plug, but have you considered integrating gdbstub rather than rolling your own debugger? I know a couple folks out there have successfully integrated it into their PS1 emulators with great success.

Things I hate about Rust, redux
I've worked really hard to keep gdbstub panic free in its minimal configuration, going so far as to write some informal scripts that parse rustc's asm output to scan for the presence of panicking code paths.

Announcing Loadstone, a secure bare-metal Rust bootloader
As a totally shameless plug, I'm the maintainer of gdbstub, a bare-metal, no_std, no_alloc, and size-optimized implementation of the GDB Remote Serial Protocol. One of the major changes slated for the upcoming release 0.6 is support for a new state-machine based API, which makes it possible to drive gdbstub directly via bare metal interrupt handlers (i.e: send/recv data over UART, handling breakpoints via the undefined instruction trap interrupt, etc...).

What's everyone working on this week (23/2021)?
Continue working on a new API in gdbstub that'll make it easier to use directly from an interrupt handler when debugging code in a no_std, bare-metal OS environment.

Designing a new architecture for Rspotify based on trait inheritance, need opinions
I ran into almost this exact same problem while working on gdbstub, whereby I an API that allowed users to mix/match protocol features however they wanted, while also preventing users from accidentally implementing mutually-exclusive features. Moreover, I wanted to have a "zero cost" way to enable/disable API features without relying on cargo features. The solution I came up with is something I've been calling "Inlineable Dyn Extension Traits", or IDETs.

Static check optimization question
For a concrete example of how smart the Rust compiler is, I have a small writeup + test-repo that benchmarks a technique I came up with while working on gdbstub that [ab]uses the compiler's devirtualization and inlining optimizations to create runtime feature flags that are entirely compiled out if hard-coded to false at runtime.
