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.

Working on integers consume more memory?
Here's an example where switching to int8/int16 sped up my program 3x, but insignificantly compared to development and compile times, namely from 15 to 5 ms. I haven't profiled it but I suspect it's because of the reduced memmove amounts in my improvised bsearch-sorted-array-insertion. Made this yesterday, solution to Advent of Code 2018 day 20: https://github.com/ednl/aoc2018/blob/main/20.c

[All years, all days][C#.NET] Joined the 400 stars club!
I made this jupyter notebook for a better idea and to directly compare different grid serial numbers. I think the condition "stop when no new max has been found twice in a row" will work most of the time. I tested a few other serial numbers and it seemed OK: the condition is only true directly AFTER the absolute maximum. But yes, there could well be other serial numbers where there is a dip of length 2 BEFORE the absolute maximum. Screenshot of the graph from the notebook: https://i.imgur.com/VXXpZnh.png

[2018 day 9] [C] Fast solution to the marble game
Well, I think I mostly got it. But what I couldn't figure out was which updates to skip, so maybe it can get a bit faster still. Time on the M1 Mac Mini was 4.3 ms for combined user+system, see below. That system time being as long as the user time is maybe from the massive heap allocation and init to zero at program start? I also tried to do it dynamically with malloc, without block initialisation, but that was a tiny bit slower, so I left it as a static array. Pi 400: 98 ms, old Macbook from 2013: 36 ms (both same deal: user time = system time). Code: https://github.com/ednl/aoc2018/blob/main/day09alt.c

[All years, all days][C#.NET] Joined the 400 stars club!
Since Christmas I've slowly been going through the past events (in reverse chronological order). For me half of the fun was building up my Utilities library, which many solutions took full advantage of. My repo can be found on GitHub here. My README contains my 6 favorite puzzles from every year.

My code can be found here on GitHub. Each day gets it's own folder, for this problem the important files are:

AdventOfCode
advent-of-code - My Advent of Code submissions. For 2021 and before, these are the original code I used, without any modifications after-the-fact. As such, they are probably not as efficient or short as they should be, because I want a working solution faster, not a better solution. For 2022 and after, these are the solutions uploaded to my YouTube channel.
