Every December I do Advent of Code and love it. Every January I try to keep it going on LeetCode and never last more than a week. 5,000 problems, no reason to do this one today, so I scroll for ten minutes and close the tab. That is the whole reason this exists. One challenge a day, the same one for everybody, so there is nothing to choose and something to talk about. Three decisions along the way: - Tests run in a self-hosted Piston sandbox on a small server, not a managed service. Eleven languages, and the compiled ones each needed their own CPU budget before they stopped getting killed mid-run. - Reading the task and running the tests works without an account. Only submitting needs one. - No ads, no paid tier, MIT licensed. It is a side project and I want to keep it that way. The part I am still unsure about: whether a streak actually motivates, or just becomes one more thing to feel bad about breaking. If you have kept a daily habit going, what made it stick?
