I’m an old-school XPer. I worked for ObjectMentor, eXoftware and ThoughtWorks. I made a commitment last year, around the same time my son was born, to change my technical environment tha same way XP had changed my process environment, so I ditched my PCs and 12 years of C/C++/Java, bought a PowerBook and started to learn some Smalltalk, ObjectiveC and Ruby.
