The O'Reilly folks asked me to write a short article about the new Program Repair Shop and Red Flags class I'll be giving at the Open Source Convention. Some of you might find the article fun and interesting:

In this year's Perl track, I'll be doing a new class, called "Perl Program Repair Shop and Red Flags." In the class, I look at some examples of a beginner's code, and then I go through the code, a bit at a time, explaining what is wrong with it and how to make it better. At the end, the program does the same thing, but is shorter, easier to understand, more robust, and more flexible. Hence "Program Repair Shop."
