This discussion will include an overview of the basics and the intermediates, as well as introduction to more advanced and possibly esoteric concepts. We'll then do an interactive workshop for various types of fun problems that could be solved with regular expressions (bring your computer). Do you have an example that you've solved that you thought was particularly interesting, or maybe one that you didn't solve just yet? If so, bring it along, or email it to me in advance if you want at alanvoss at hotmail dot com.
