  • Today I Learned

    TIL is an open-source project by Hashrocket that exists to catalogue the sharing & accumulation of knowledge as it happens day-to-day. Posts have a 200-word limit, and posting is open to any Rocketeer as well as selected friends of Hashrocket. The original Rails application was my Hashrocket apprentice project. We open sourced TIL in early 2016, and today I maintain the project with my fellow Rocketeers.

    Written in Elixir/Phoenix.
