1. A gentle introduction to actor-based concurrency.

2. Source code from this article. All of the code from this article is in Practicing Ruby's example repository, but the links below highlight the main points of interest:
   • A solution that leads to deadlocks

   • A coordinated mutex-based solution

   • An actor-based solution using Celluloid

   • An actor-based solution using a hand-rolled actor library

   • Minimal implementation of the actor model

   • Chopsticks class definition

   • Table class definition
