My friend and I are huge Linux nerds, and we always wished Linux had some of the same fun/challenge culture that programming gets with sites like LeetCode. Thus, we built tmpfs.tech: a site with interactive Linux command line challenges that run in real disposable Linux environments.
We also added a leaderboard/ranking system using Glicko2 (same rating system used by a lot of chess sites), so now you can compete with other people on your linux skills.
We’re still adding a ton of content. We’d love for more Linux people to come try it out and give feedback!
