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

How involved do these problems get as the month goes on?
Polyglot challenge is fun. Some languages really bend the mind. If you need some inspiration: https://github.com/ttencate/aoc2016 https://github.com/ttencate/aoc2017

[Request] On Advent of Code calendar
I've found that this suits the most for a screen to play Bad Apple on. I believe this is an appealing concept.

[YEAR - 2015] Every day with a new language !
Heh, I still mean to do this for 2015 too, but not using any of the languages I used in 2016 or 2017. They are getting rather obscure now...
What are some alternatives?
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.
