I attended my first meeting of the Dallas Ruby Brigade last night. It was a lot of fun. Adam Keys and Geoffrey Dagley did a little ping-pong pair programming. They worked on the Credit Card Problem on Ruby Quiz.

It’s always interesting to see someone else’s code, but to be able to watch them right it was really enlightening. Geoff and Adam took turns writing specs and then adding the code to satisfy the spec.

I’ve done a little test driven development, but never behavior driven development with RSpec. I can see where it would come in handy when dealing with a non-technical client.

Adam demonstrated some serious Ruby-fu when solving the Luhn algorithm part of the quiz. I found a good article on Vitamin that talks about some of the array tricks he was doing.

Unfortunately I got tied up in traffic and didn’t make it to Freebirds before the meeting. I will be there next month.
