I said we couldn't as this is a name for a programming language and everyone would think we named her after that (me being a programmer)
I don't get why that is an issue. I actually named my daughter after Ruby, a beautiful female name AND a beautiful programming language. Every time when asked if the Ruby being the one as in "Max and Ruby", I often need to emphasize that it's actually the one as in "Ruby on Rails", :) A bit much geeky? Probably. Being a programmer, I am proud of what I am doing.
BTW: I named my son after Ken Thompson, the guy who invented UNIX, the greatest programmer IMHO.
