Brian Marick talks to Daniel Steinberg on a wide variety of topics. Brian asks, who's smart enough to program?, and describes how he met Andy and Dave at the Agile Manifesto summit. He talks about using Lisp, Smalltalk and Ruby, and about introducing programming to testers. Brian also shares the secrets of Domain Specific Languages (DSLs), and of course, his new book on Ruby Cocoa: marrying Ruby with the uber-cool Mac OS X Cocoa GUI framework, and test driven development with Ruby Cocoa code.
