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.

Val, a high-level systems programming language
No longer does Wasm/WASI need JS host! There are many spec-compliant runtimes built for environments from tiny embedded systems up to beefy arm/x86 racks:
- https://github.com/bytecodealliance/wasm-micro-runtime
- https://github.com/bytecodealliance/wasmtime
- https://github.com/wasmerio/wasmer
- https://github.com/tetratelabs/wazero
- https://github.com/extism/extism (disclaimer, my company's project - makes wasm easily embeddable into 16+ programming languages!)

Blog Post: Reasonable Bootstrap
The WASM core 1.1 infrastructure is already available in a very strict defined more or less guarantied compatible form on nearly any final target. Even on very small devices for embedded computing (WAMR takes less then 85kB and supports even trusted computing etc.) and in contexts, where usually no other low level development tools are available (for example within the context of Webbrowsers, sandboxed execution etc.)

WASM vs Native Rust performance
WAMR and it's different AoT preprocessing and execution modes could be even more efficient. ;)

Wasm-bpf: Build and run eBPF programs in WebAssembly
Wasm-bpf is a WebAssembly eBPF library, toolchain and runtime powered by CO-RE(Compile Once – Run Everywhere) libbpf and WAMR. It can help you build almost every eBPF programs or use cases to Wasm.

Ruby Adds Support for WebAssembly: What is WebAssembly and how it benefits Ruby devs?
Running a Wasm application outside the browser requires an appropriate runtime that implements the WebAssembly VM and provides interfaces to the underlying system. There are a few competing solutions in this field, the most popular being wasmtime, wasmer, and WAMR.

Learning Embedded rust
A very interesting solution for high level interface access by less professional developers could be seen in pikascript, which works even on very small devices. WAMR is another project with similar capabilities. Both of them can be very well combined with core infrastructure realized as embedded rust code.

Wasmtime 1.0
Seems the micro runtime also released 1.0:
https://github.com/bytecodealliance/wasm-micro-runtime
But why does it not have binaries compiled and ready?

Why choose async/await over threads?
thanks. looked that up. for the curious: https://embassy.dev/

Avoid Async Rust at All Cost
Async solves different problems, you can, for instance, have just a single-threaded CPU and still have a nice API if you have async-await. It might not be so cool at a higher level as Go's approach of channels and threads, but it's cool in embedded, read this:
https://github.com/embassy-rs/embassy?tab=readme-ov-file#rus...
"Rust's async/await allows for unprecedently easy and efficient multitasking in embedded systems. Tasks get transformed at compile time into state machines that get run cooperatively. It requires no dynamic memory allocation, and runs on a single stack, so no per-task stack size tuning is required. It obsoletes the need for a traditional RTOS with kernel context switching, and is faster and smaller than one!"
I'm just toying with Raspberry Pi Pico and it's pretty nice.
Go and Rust have different use cases, the async-await is nice at a low level.

Is anyone using coroutines seriously?
I have not yet dipped by toes in the Rust waters, but reading about the embassy project is actually what piqued my curiosity about using C++ coroutines in embedded. Are you familiar with the project or have you found it lacking?

The state of BLE and Rust (no_std)
I think I get the basics (shoutout to the Rust Embedded Working Group!), and I've started looking for the stack I'd be using. I think Embassy is really amazing, as well as the work of the ESP team -- hats off.

The State of Async Rust
> not good for embedded
embassy begs to differ
https://embassy.dev/
async/await is really just a syntax for building state machines in a way that resembles regular code. It's compiled down to the same code that you would write by hand anyway (early on it had some bloat in state size but I think it's all fixed now).
And embedded has a lot of state machines!

Asynchronous Rust on Cortex-M Microcontrollers
You can run multiple executors at different interrupt priority levels (with multiple tasks per executor), which allows tasks on the higher priority executor to interrupt other tasks. Here's an example https://github.com/embassy-rs/embassy/blob/main/examples/nrf...
