I'm really excited for this year's AoC, and trying to get other devs at my work involved too!

Last year I tried to solve at least the first few days in a bunch of different languages, doing Red/Green TDD so I could learn how to set up a basic project and do tests in languages I was less familiar with. Still trying to decide if I should take that approach again this year or focus on getting every day done in a single new language.
