QMK and Keyboards
Gotta give a shoutout to kanata[1] which I have used daily for years at this point after giving up on QMK-powered keyboards.
QMK itself is great, but I was never able to find a non-columnar split ISO keyboard to use it with. Eventually I reluctantly settled on the Logitech K860[2] and I'm now happily using my favourite features from QMK with kanata at the software level.

[2]: If I'm behind the times and there is now a QMK-compatible keyboard that looks like this, please let me know!

Emacs boffins guide to reprogramming keyboard for EXWM?
This is not in Emacs, but if I can't modify my keyboard's firmware (e.g on a laptop), I use Kanata https://github.com/jtroo/kanata. It works by creating a virtual keyboard in Linux (and uses a filter driver or process hooks in Windows), so it can work in any program as they just see a normal keyboard.

HHKB Studio: The New Happy Hacking Keyboard with TrackPoint
Besides the better caps word (by the way, you can have it in software in Win/Linux apps like https://github.com/jtroo/kanata/blob/main/docs/config.adoc#c...) you can also toggle capslock with e.g. a double tap while having on-hold functionality to the more useful Control, so you still wouldn't need to hold any modifier key

Kanata: Improve keyboard usability with advanced customization
One particular approach that one might find it interesting is how the configuration is laid out (using S-expression from Lisps).

Learn AutoHotKey by stealing my scripts
Kanata[0] is amazing. It support both Linux and Windows. But I'm yet to try it on windows because my majority work is on linux.

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.

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...
