Introduction to Elixir for Rubyists
summary
Shows concrete claims and live hacks: actual Elixir features used (gen_server/agents/tasks, pattern matching and the pipe operator), platform tools and versions (R17 maps, Erlang VM, mix, Hex), and hardware demos: Sphero and AR.Drone, Raspberry Pi GPIO with PWM, Pi Blaster, and JInterface to Android. Demonstrations build an LED, an RGB PWM driver, and a tank remote control; one motor controller dies and gets replaced with an Arduino workaround, so some pieces fail then recover. Timings and numbers appear (11 hours of screencasts, 2,000 VM reductions, Pi $35).
