I’ve set out to learn Ruby and eventually Ruby on Rails so that I can better integrate with the programming team. I’ve programmed in perl and php before though I have never reached a level where I felt I had mastered them. There is a belief that you need to practice an art (and programming is both a science and an art) consistently for ten years before you can truly master it. As someone who spent almost 8 hours a day in Illustrator 8/OS9 for a year, and only partly mastered the sub-set needed to create perfect signs, I do believe it is close to the truth.
