Don't know why this was downvoted. You should make your resume as to-the-point as possible, even keeping a spreadsheet of different versions of pieces of information to more easily taylor it to the job in question. Unless your intention it to work with something, drop it from the CV. Recruiters don't like anything unexpected. Don't surprise them.

Keep it objective. They don't care you think you are a kickass Rails developer and they will not react positively to what they can interpret as a big ego.
