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.

Ask HN: What Are You Learning?
I'll jump on your thread because it's similar in some ways. I'm learning Forth and more importantly, how to implement Forth from scratch. I'm targeting bare metal Raspberry Pi (especially the Zero at first). Looks like someone already combined bare metal Pi stuff from Alex Chadwick and an arm port of jonesforth (by Rich WM Jones which is in assembly but runs on Linux x86) but it also uses a lot of C libraries and stuff and I just want everything to be a minimal assembly kernel and then build up from there in Forth itself. This is the branch that has taken things the farthest that I ran across: https://github.com/Avoncliff/pijFORTHos

Ask HN: Does anyone use a Raspberry Pi as your main computer?
Not as my main computer, but as my digital piano sidekick, a USB output from the piano goes to my Raspberry Pi which runs Pianoteq (makes the piano sound like a $100k piano). Optionally, the Pi lights up some addressable LEDs coinciding with keys.

2,400 LED Icosahedron
A nice "gateway drug" is an addressable (programmable) LED strip. Hook it up to a Raspberry Pi or Arduino and have at it! I bought cheap motion sensors and will be installing a strip along the inside of a staircase to light up when I approach it.
https://github.com/whyboris/Arduino-LED (see "stairs.ino")
Another project of mine is having the LEDs light up as I play piano:

Unsure where I'll go after I finish these projects, but LEDs are so much fun!

Ask HN: What Are You Learning?
A fun tech-related project is hooking up an addressable LED strip to a digital piano and making the strip respond to your key presses on a Raspberry Pi.
My repository for this (code finished, just need to add photos and add a write up about how to use):
https://github.com/whyboris/Digital-Piano-LED
I added a feature that the left and middle pedal buttons navigate through sheet music (PDF left/right button). And I'm also running Pianoteq which makes any (even dinky) digital piano sound like a $100k grand piano (or any piano you pick for that matter) https://www.modartt.com/pianoteq
What are some alternatives?

OpenPianosMap - The goal of this project is to create an open source map of accessibles pianos. Data will be hosted on OpenStreetMap
