For email, use firstname.lastname@example.org. Also, feel free to add me on Google+ (not very active there yet) or follow me on Twitter. (As for Facebook, I generally try to limit my friend list to real-life friends and acquaintances, but feel free to follow my FB page.)
If you’re looking for internships, PhD positions or the like, there is no need to contact me directly. Any positions available are announced at the department and faculty web pages.
If you need help with computer crime, you’ve come to the wrong place (and probably misread my tutorial on hacking).
