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.

I built a column staggered keyboard with firmware written in Rust!
As someone who had only done embedded programming in the Arduino IDE, utilizing the defmt crate for logging with OpenOCD and GDB was an amazing experience. Although I still had no idea on to implement USB-HID for actually sending the key reports, until I discovered the usbd-human-interface-device crate and everything became so much easier. I just needed to create an iterator over Keyboard events and the crate would handle the rest as an added benefit the crate also supports multiple devices, so adding mouse support was as easy as creating a separate iterator over WheelMouseReport.

00Key a 75% Keyboard
I only use keyboards running QMK or ZMK, so:
My Caps Lock key is a Control/Escape key (when tapped it behave like a Escape, when hold it's Control), and my left Control is a one shot layer switch key [1], which means I tap LCtrl once, and then press Caps Lock + 5 to get Ctrl+F5. Doable with single hand and more ergonomic as I have an unusually small hand.

Principles for Keyboard Layouts (2022)
I agree that reduced finger movement is a crucial step in achieving typing efficiency. This is nicely solved by mod tap modifiers in QMK/ZMK[1] where key acts as a char when tapped and as a layer while pressed.

Debugging a Failing Hotkey
If you have a keyboard that runs QMK firmware[0] with the VIA[1] feature enabled[2], then there is a convenient testing app available from the same place you customize your keys [3].

Just setting up my first corne layout. It will take a while for me to get used to this wow... It's taking so long to type. Attached is my layout, and I mainly use c# on visual studio. Any concerns/advice/suggestions are welcome. It will take a while for me to reply on this thing though.. haha..
I made a layout that I'm happy with. Spanish is my native language, so it has characters like the accents and 'ñ', but it's meant to be used for programming as well. Visual Studio uses a lot of Ctrl and Ctrl + Shift shortcuts, so I left them in the same place as the default Corne layout so I can press them both with my pinkie finger. Perhaps some of the ideas are useful to you.

Adafruit Feather RP2040 with USB Type A Host as a QMK converter board?
Also, it would be possible to do this for the RP2040. However, it needs some work to get working. but for example: https://github.com/qmk/qmk_firmware/pull/20999

If anyone knows of a good tutorial on how to make this tft display useful on a board controlled by an rp2040 and flashed with qmk configurator, I would be most grateful if you could point me in that direction. Gracias!
Ok, it's an ST7735, not too different from the ST7789. You should be able to get running by looking at their files in the QMK repo and going from there. You should also check their resources page.
