When: 12th of May

Erlang has not gained a huge following as a programming language but it is being used to build scalable chunks of infrastructure. From messaging to queues to document databases, Erlang is increasingly providing the service backbone for applications written in a variety of languages on top of it. Even if you code in Java, Ruby, Javascript or C# you may be relying on Erlang to provide reliability, distributed services and huge lightweight concurrency.

The use of different languages to solve different problem spaces has also given rise to the need to create lightweight platform and language data exchange formats, the most famous of which is JSON but includes Apache Thrift and Protocol Buffers.

So whatever you program in you should known what Erlang can do for you.
