This lecture introduces Erlang for Haskell programmers), taking parallelising quicksort as an example, both within one Erlang VM and distributed across a network. The latest version of the Erlang system can be downloaded from here (Links to an external site.). There is a Windows installer. Many linux versions have an Erlang packagage available, but not necessarily a package suitable for development of Erlang code, and not necessarily the latest version. On Ubuntu, try

sudo apt-get install erlang-dev

If that doesn't work or you can't find an appropriate package, build the VM from source.

A version of foo.erl can be found here. (This file is provided as-is, in case you want to experiment with the code from the lecture--there are no comments, for example, and there is experimental code that didn't make it into the lecture).
