Creating a Distributed Hello World System in Elixir

The article revisits the 'Hello World' program, but this time with the goal of building a distributed system using Elixir. It starts with the basic implementation of 'Hello World' in various programming languages and then introduces a more complex project involving multiple distributed nodes that can automatically discover each other and exchange greetings. The components of the project include setting up an Elixir application with a supervision tree, using UDP for node discovery, and implementing a 'NodeManager' GenServer to handle communication between nodes. The article demonstrates how to set up broadcasting messages over UDP and monitor nodes to greet new members in the cluster. Ultimately, this exercise serves to illustrate the concept of distributed systems while intentionally overengineering a simple task.
