I dropped off on Exercism.org once I got to the Zebra puzzle. I can’t get it working. I hope to give it another go soon.

I have however been participating in Advent of Code. Only 12 days this year. It was a lot so I am ok with that, but I do think that without a global leaderboard it is missing something. Even if people did ruin the global leaderboard with their “enthusiasm”.

I like all the visualizations you can see on the reddit page. So I decided to try my hand at one this year. Today we were trying to connect extension cords between pairs of closest junction boxes. On part two they want it connected so that is is one single big circuit. That is what I visualized.

Extension cord mesh

That’s a lot of extension cords and junction boxes. I made my code spit out a wavefront obj file so I could open it in blender. Unfortunately I don’t know enough Blender to render it well, so you just get a screen grab.

Anyway I thought that was fun. Looks like I should have used Kruskal’s algorithm.
