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.

[2018 day 9] [C] Fast solution to the marble game
When I get back home after the holiday weekend I'll try benchmarking on my machine properly. But here's my version (in Common Lisp): https://github.com/rabuf/advent-of-code/blob/master/2018/2018.09.org

Programing midlife "crysis"
I'm partial to Common Lisp, but both Scheme and Racket would be good choices as well. There's a few of us who've been using CL the last few years to solve (nearly) every puzzle. If you want to see (not always great) solutions to the puzzles in Common Lisp, here's my repo, of course don't look at days you haven't solved yet unless you want spoilers. But it can give you a feel for how CL can be used to solve the problems. I'd intended to revisit them and clean them up, but never got around to it.

[2020 Day 10 (Part 2)][C++] Non-memoization solution!
Interestingly, I think that solution is rather near the memoized version in one key regard. It's not memoization, however it's still storing all the results (the count for every joltage adaptor). You can massively reduce its storage by going with something like my solution (C-f for "part 2", there are two solutions one in Common Lisp and one in Ada), which is like the non-memoized iterative fibonacci series (psuedocode, pythonesque):

[2023 Day 5] Exlplanation Like I'm 5
In the spirit of the Day 5 ALLEZ CUISINE! challenge to ELI5 (Explain Like I'm Five), here's a tasty explanation of how my algorithm works using only a large bucket of Red Vines and a knife. It says to use lined paper, but if you try this at home consider aligning things on a cutting board.

Bonus solution in Go (golang) because I was confused about why my Elixir solution didn't work and decided to implement from scratch in case I'd done something dumb. The Go one also got the wrong answer, but took less than 100ms instead of a minute, so I could try out lots of tweaks that didn't change the answer.

I spent time this afternoon sprucing up my helpers for the iex REPL. I spent a bunch of time poking at things in IEx the last couple days and wanted to make sure I would minimize keystrokes if I needed to debug things on my phone while drunk. Turns out Thursday night > Friday night > Saturday night in terms of difficulty, so all those macros have so far saved me zero seconds :-)
