Disclaimer: Forget about my affiliation, this is my personal list of things that I am going to enjoy at the UC.
Old school technologists don't think kindly of PHP. Its adepts are believed to be sloppy programmers that create brittle applications. It takes programmers like Sebastian Bergman to level the score and to show that a good programmer is shown by best practices, not by the choice of language.
The best thing a good programmer can do while developing an application is testing. Sebastian shows why you should do it, and how. Not only that, it will show you how easy it is. At the end of this session you will wonder how could you have survived for years without unit testing.
PHP programmers, mark your calendars!
