a Guided Introduction to Elixir - Part 6 of 6
summary
A guided walk-through of a real Elixir side project: code for an umbrella app using Phoenix, Ecto and GenServer/Registry pubsub to run a tiny distributed MUD with mobs, heartbeats and a reaper. The demo shows actual files, use of structs and Dialyzer, a one-second heartbeats timer via PEck/timers, offloaded births as Tasks with a 60 ms task timeout, supervision trees and a simple circuit‑breaker pattern — parts work, some APIs and VM networking still need fixing.
