Heyyyy it's released! https://github.com/jepsen-io/maelstrom is a distributed systems learning tool: a workbench where you can write your own "distributed" systems in any language, using JSON messages via STDIN/STDOUT. Wanna write a gossip system in Perl? A transactional KV store in bash? Maelstrom will run it, show you how messages flow through the system, and verify key safety properties.
Transneptodon is a community for people who like stories, games, games about stories, stories about games, probably also computers, cooking, language, and definitely social justice!
