I'll probably be working on a new edition later this year, focusing on incorporating a lot of the material I already post about computer security and how it applies to programming. However, I'm looking for other information to include, so please post a response to this post if there is anything special you would like me to cover in the next edition, e.g. unit testing, refactoring, more web development, etc.
Naturally, if you don't let me know what you want to see, I won't know to put it in. I'd like the next edition to me more of a collaborative effort, so if you have knowledge of a subject that hasn't been included yet, feel free to let me know and I'll see about incorporating your write-up into the book.
