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.

powering an esp32 with batteries
If you look at recharging the device a good charging circuit and low quiescent LDO is needed. Andreas Spieß (popular YouTuber in this domain) compared several developer boards. The outcome is for me to go for „Firebeetle“. A project of mine gives details: https://github.com/Torxgewinde/Firebeetle-2-ESP32-E

Keeping time while in deep sleep possible?
My PIR sensor runs from battery and uses the RTC to estimate battery runtime: https://github.com/Torxgewinde/Firebeetle-2-ESP32-E/blob/main/Firebeetle_DeepSleep.ino

ZED 2 Kalibr Calibration
There is another person who encountered - seemingly - the same issue https://github.com/ethz-asl/kalibr/issues/426 but there are unfortunately no tips on how to fix this.

Camera Calibration Tool (Pinhole) w/ Re-projection Error Metric
I have tried to compile this one https://github.com/hengli/camodocal but I always get an error, and it looks like the repo is no longer being maintained. https://github.com/ethz-asl/kalibr This one works but it looks like it doesn't provide any error estimate/"goodness" score. I also tried to write my own tool with OpenCV but there I get huge re-projection errors (~1E20). And the ROS http://wiki.ros.org/camera_calibration package also doesn't provide any metric (as far as I can tell).
