VIDEOS

Zip and slide! (Advent of Code day 1)

In this episode I talk about what AoC is, show how I approached the tasks of the first day, and share some thoughts about how I would like to improve my workflow in the next 24 days.
Jakub Kozłowski (@kubukoz)
Ep 15: Advent of Code 2021 Day 1. Is it Traverse?
