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.

Kalman Filter Tutorial: Kalman Filter from the Ground Up
They are widely used in narrow circles :)
Two of (arguably the best) open source RC aircraft flight controllers (ArduPilot and PX4) are using extended Kalman filters in their state estimators (essentially sensor fusion that provides attitude/position estimate):

https://github.com/PX4/PX4-Autopilot/blob/main/src/modules/e...
I'm not that familiar with cleanflight/betaflight/inav scene to know what the FPV racer flight controllers use.
- Does anyone know about a good avionics related open source project for learning purposes?

Power electronics and embedded systems
Actually, even the General Aviation pilots who actually manually manage their own load-shedding during a mission would quite like automated power distribution and management systems... and if you felt like taking on that sort of work as a hobby project to cut your teeth, I bet the guys at the (open-source) PX4 project would bite your hand off...

DJI drone flight log viewer
As a flight pilot engineer you have to find a sweet spot and balance logging too much and too little. Writing logs to an SD card has huge costs that come with it, that's why you don't want to log too much. Logging too little and you can't debug issues later on properly.
PX4 also has lots of "topics" logged at around 1/10, e.g. hover thrust estimate every 100ms:

- Has anyone programmed a drone?

Help me choose a flight controller.
Okay, but nowadays most people talk about “Pixhawk” as an open-standard hardware platform and PX4 as the software. The source code is at https://github.com/PX4/PX4-Autopilot and they call themselves “PX4 Autopilot Software”.

Best way to start getting involved with open source projects?
As an example, PX4 is a popular open source drone autopilot software: https://github.com/PX4/PX4-Autopilot

Having trouble finding embedded engineers, should we even be looking for embedded engineers or more optimization experts?
I am working as a Remote Embedded Software developer for quite a while now and there is no obstacle in Remote work. If I am missing anything, parts are arriving in under the week. That said, I never had a better work-life balance in the last 10 years. Anyone who said Embedded is not possible to do remotely just check any open source flight controller project (in my case PX4).
