Rubx, also known as Ruby Boobie, is a nice spoiled girlie bot that runs on Twitter. She listens when you talk to her and when you do, it'll better be with Ruby: She will interpret your tweet in Ruby and reply to you with what your code returns. How does it work? You send a message to her:

@rubx "The day I was born it was a "

And @rubx will reply:

@damog "The day I was born it was a Wednesday"

Go see more about her (examples, FAQ, etc) on axiombox.com/rubx or on her Twitter profile.
