My solution in Common Lisp.

Dot file generated by my code and then run through fdp from Graphviz.

Just a simple relief-shaded image like you might find on a map. Principally generated with GDAL. The particular commands used are at the bottom of my solution code for the day. I also made a more flat version, which shows the elevation colors better, but really doesn't feel right in terms of elevation.

The code is written in Common Lisp using Cairo and ffmpeg. https://gitlab.com/asciiphil/advent-of-code/-/blob/master/2022/09.lisp

So I spend more time analyzing the input calculation. I wrote up that analysis and committed it to my repository, too.

This was a bit difficult. My original part one solution worked completely differently to what I had to do for part two.

My solution in Common Lisp, 2335/2041.

No. It's just here, as part of my Advent of Code repository.

The code is at the bottom of my day 9 source file, in Common Lisp. (The AdvMAME3x code was something I originally wrote for my 2020 day 20 visualization.)

As a side note, I took inspiration from a post the other day about adding AoC badges to your repository README file. I use GitLab, which lets you define badges as properties of your repository. So I added badges to my repository's header area, driven by a JSON file in the repository. The JSON file is updated manually by a script. (I might add some automated updates at some point, but manual works okay for now.)

I've done every year in Haskell (2015 2016 2017 2018 2019 2020 2021), and so have several other people such as /u/glguy. I don't see if /u/mstksg has anything published for 2015 but they've done 2016 2017 2018 2019 2020 2021 along with some pretty good writeups, I recommend checking those out.

I benchmarked all 25 days in 4 languages (using GitHub Actions, which performs worse than my local dev setup, but feels more fair for reproducibility). Can't get any pretty animated output, though.
