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.

Blinkenlights and PDP-11 Assembly Language.
I got inspired to make my own version of blinkenlights. This is before I heard about projects like the blinkenbone or PiDP-11. My version with 3D models to print and the Ada source code is here, Pi-Mainframe I think got simh running on it, booted RSTS/E and am now exploring PDP-11 assembly language for the first time since about 1985. Some of my routines are here, PDP-11 stuff. I hope that I've learned a few things since 1985 ;-)
