This exercise contains a script for de-identifying a postgres database. It uses Rails to generate some sample data, so that it has something to work on. It uses rvm to virtualize the ruby version and gemset, so it has a .ruby-version and .ruby-gemset. You'll need to have postgres installed as well.
