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.

[2021 day 6] What's you're fastest solution?
This in C runs in 215 us on a Pi 4 with the cpu in performance mode: https://github.com/ednl/aoc2021/blob/main/day06.c

[DAY 6] C# solution with commentary
I took a few hints from the solutions thread and made this in C which executes in 0.4 milliseconds on a Raspberry Pi 4: https://github.com/ednl/aoc2021/blob/main/day06.c

[2021 Day 18] [C++] Overcomplicated solution after a lot of grief and hair loss.
Good outcome. I'm not well versed in C++ so I can't say much about it. For my solution in C, I figured that a full-blown tree was too much work and also not really needed if I kept track of the level myself, because everything is always in the same order left to right, just expanding and contracting. So I used a linked list and a SF number became an array of SF digits where each digit is a struct { left,right,level,value }. I guess the trickiest bit was to do the accountancy of keeping everything linked correctly when exploding and splitting.

[2021] What did you learn or take away from AoC 2021?
The constant time thing is counting fish in an age histogram mod 9, right? I think that idea floated around the solution thread. I am no longer sure if I saw it there first or came up with it myself..... but here's my implementation in C: https://github.com/ednl/aoc2021/blob/main/day06.c

Good ol' C code. Very simple program once you think of making a circular buffer from the population histogram by age bins, and simulating every day. I got stuck for a while trying to come up with a direct mathematical function which never gave me the exact number. The crux:

C, which takes some bookkeeping but it can be fast. I didn't push for every last drop of speed but still: about 3 ms on a Raspberry Pi 4 (1.8 GHz overclock, Buster desktop, not very quiet so I picked a good run). Code with lots of comments

Oh also lost about 2-3 minutes on part A initially trying to use my challenge.TileMap so I didn't have to worry about computing x/y but converting to/from rune all the time was taking way too long and was hard to follow. Man, I can't wait until generics!
