I had a great time talking to the folks at the Houston TechFest. Much thanks also to Addison-Wesley for sponsoring my trip to Houston. If you are interested in becoming an technical author, let me know and I can put you in contact with the editors at Addison-Wesley (email@example.com).
As promised, my slides and code are online: www.scottseely.com/downloads/HoustonTechFest-Seely-WCFRIA.zip.
Let me know if you have any questions about the code, the presentation, or life as an author.
