It is a conference on pattern languages of programming. About six months ago I saw a tweet by Eduardo Guerra asking if anyone had some cases where certain patterns were applied. It was a big coincidence, since I was working on Apache Commons Functor and some Jenkins plugins, both projects with cases that could be used in his paper.
So I joined Guerra and gave my small contribution to the paper that has been accepted for this edition of SugarLoafPlop. Guerra also went there to give a talk and participate in an open discussion about several papers, including ours.
I simply love when these things happen, it was great work with Guerra, and even better for being able to use Open Source examples in our paper.
