I'm currently doing the "Advent of Code" daily coding puzzles and have quite a bit of fun doing them.
While I originally did not plan to make them public, on day 3 I stumbled on Binder, a website that makes Jupyter Notebooks (One of my favorite coding tools.) hosted in a Github repo available in a hosted, interactive session!
So, to give this a try while doing my Advent of Code, I started this repo. Not sure yet if I'll add days 1-3, since these do not live in Notebooks yet (and the code's ugly and badly documented), but we'll see.
