When my wife was heavily pregnant we were stuck thinking up girls names. (No idea at this point if a boy or a girl). She suggested Ruby and 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). So I jokingly started to list as many programming languages as I could: Perl, Haskell, Fortran, Lua, Brain Fuck, etc. She stopped me at that point because "that's a beautiful name" (no, not that one). But, because we live in Germany we must conform to naming your child a proper name, so we gave her a "normal" middle name.
We were confident the baby would be a boy, but were wrong, and in the summer of 2011 our baby daughter was born.
Most people are happy with the explanation that it's Portuguese for Moon. But I have had a couple of knowing looks from colleagues. Luckily, the German authorities were fine with her double-barrelled "normal" name.
