He has spent over a decade doing vulnerability assessments, programming, and network engineering for the government, military, and private industry. Since his first encounter with Apple DOS at a young age, his eventual mastery of the infuriating System 7, and witnessing the advent of OS X, he has always wanted to know the inner workings of the newest Cupertino magic boxes.
