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.

Faer-rs: Linear algebra foundation for the Rust programming language
On the contrary, it seemingly can be used to make a BLAS implementation (example in a PR: https://github.com/sarah-ek/faer-rs/pull/37)

Faer 0.11, a general purpose linear algebra library written in Rust
`faer` is a collection of crates that implement linear algebra routines in pure Rust. the aim is to eventually provide a fully featured library for linear algebra with focus on portability, correctness, and performance.
see the [official website](https://faer-rs.github.io) and the docs.rs documentation for code examples and usage instructions.
---
this release implements the initial design of the high level api (see https://docs.rs/faer/0.11.0/faer/), which should allow users to get started with writing easy to read code without having to deal with managing memory or multithreading settings on their own.
i also added a thin compatibility layer with ndarray and nalgebra. this way users are able to mix and match libraries if they wish to do so, or to help with migration to different libraries

Help understanding the state of ndarrays and linalg in Rust.
Faer is comparable to Eigen in most of their benchmarks, so they are getting closer.

faer 0.9 release: low level linear algebra library
performance compared to openblas is shown in the benchmarks on the repository, and on the website. (ndarray is using openblas)

Has anyone worked on a math library before?
currently working on a very efficient linear algebra library https://github.com/sarah-ek/faer-rs

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

Accessing the Pinecil UART with Picoprobe
Running the Embassy RP2040 USB CDC ACM serial example takes about 5 seconds on a Pico.

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.

And this is how to do it using embassy, which is an async framework for embedded in rust:

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...
