I have occasionally posted on the topic of genetic programming, as a possible way to drive rapid software development.  Some of these posts have drawn requests for more material.  For those who are interested, I posted a summary of my (very old) research and source code here.   The material includes Doodle Garden, a windows application that evolves pictures, the GPQuick C++ framework, sample code for using a Meta-GA to evolve financial trading rules, and a discussion of advanced techniques like distributed clusters, Meta-GA, and symbiosis.
