If you click over to my profile, there's an Amazon reading list I made up to answer the question "what should I read up on to get better at appsec". I think WAHH is #2 or #3 on it.

If you're a talented programming (we especially like talking to people who are good in C, but we're happy to meet anyone) and you're seriously interested in working from Chicago, NYC, or SFBA doing appsec, but don't feel like you have the background, drop me a line. My usual next step for people who I think would be ready to interview with us but for some web app knowledge is to shoot them a copy of that book. Infinite free books is a small perk here.
