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.
gdbstub
-
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.

gdbstub 0.6: An ergonomic, #![no_std] implementation of the GDB Remote Serial Protocol in Rust - now with async support!

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.

Noctane: WIP PSX emulator
If you want to check it out for yourself, the codebase is written in Rust and available at https://github.com/norepimorphism/noctane. If you don't want to mess with compiling (I don't blame you), a precompiled Windows executable of the debugger demo is available here.

Noctane: a highly WIP original PlayStation emulator
I would really appreciate it if you did! What makes me happier than releasing software is seeing other people read and use it :). I would say I'm most proud of my algorithm for constructing a CD-ROM file system hierarchy, as well as the design of I/O registers, the workings of which is explained in a comment here.
