Erlang actors, supervisors, OTP and even more crashing

Last time we built simple chat server in Erlang with Marian.

This time we will explore advanced Erlang concurrency models and OTP library (supervisors, finite state machines etc).

Tomáš Morstein will share his experience of using Erlang in production.

Expect even more crashing. No prior knowledge of Erlang is required, but safety helmets are mandatory.
