Part two of my introduction to programming Erlang is available on IBM developerWorks:
Erlang is a multi-purpose programming language that is primarily used for developing concurrent and distributed systems. Part 1 of this series introduced Erlang and how its functional programming style compares with other programming paradigms such as imperative, procedural, and object-oriented programming. In Part 2 you will use some of the advanced features and functionality, starting with basic functions and moving on to concurrent programming, processes, and messaging. These work together to support distributed programming, a powerful feature of Erlang.
