He invented the word "Jailbreak" and got kicked out of Rochester Institute of Technology for rewriting his student ID card with SQL injection to get into any room and get free food/drink from vending machines.
He's a legend.
Those things are just part of the common college experience. I got into rooms with an under-the-door coathanger contraption (always fun seeing the reaction of the person who got locked out realize wait, anyone can just do that?), and got free snacks due a firmware bug triggered by invalid card reads. Getting kicked out for those things is a good example of how technology has escalated the severity of punishment, because people who can manipulate it are considered witches.
You can also sometimes catch him on twitch coding live.
He codes in vim at like 120wpm and is super entertaining.
