Advanced Multithreading in Ruby
summary
Shows concrete concurrency primitives and working code: futures, promises, agents that queue updates, timers, actor pools and a Ruby implementation of an Erlang-style supervisor that restarts workers. Uses the concurrent-ruby gem, demonstrates immutability with hamster and contrasts thread safe collections, swaps blocking RestClient for em-http-request to avoid blocking the reactor, and wires AMQP/RabbitMQ timers to a five-worker pool so the examples actually run and recover.
