This year both Ruby and I are turning 25 years old. We all also have to admit that at some point we have found, or written, Ruby code that was not that great. Even the code that was pretty good at one point, could now be improved, due to the evolution of Ruby.

Let us refactor some code in long-lived Ruby and Rails open source projects and what can we learn while doing it.

Ana is in love the open source development. She is currently working at SUSE on the Open Build Service frontend, one of the oldest Rails projects that is still in use.
