A bodybuilding hacker. I can't stop laughing at the idea.
Tom Clancy actually used that idea in one of his books in the
Net force series.
But good on you for teaching him, I'll say that - to be honest, I actually admire the skill, I'm not a very good teacher.
You're all the bane of us poor systems administrators/engineers.
Heh, you'd have hated me and my friends in high school. We tried to tell the Head of IT and main sysadmin that the school's computer network had some serious security flaws, and his response boiled down to "I built and tested it all myself, that's not possible. Punk kids, what the hell do you know?" and shooed us away.
Of course, aggravated by this response, we promptly blew through every single security measure he had put in place, from the user account system all the way through to the custom programs he'd written to allow teachers to turn the internet, email and printers in any particular classroom or on individual computers on and off. Within a week, we owned the entire network top to toe, with nowhere we couldn't go and nothing we couldn't do.
He didn't believe us, till we raised the issue with him again, and then when he turned us away again, as we were going out the door, we quoted back his username, password, the last five sites he visited, and a few comments he'd left in his code that was part of the Teacher access only program for turning on and off the various student access permissions.
So, he pretty much immediately tried to have us expelled, but we basically said "Hey, come on, fair suck of the sav, let us present out case to the principal" - an idea the principal went along with, and when we explained the layman version of what we did, exactly, we got off with a month of detention(which was served working on the network, fixing the security) and the satisfaction of the principal telling the headteacher what was essentially "Wait, so you're the head of IT and the sysadmin in charge of everything, and you got your ass handed to you by three punk kids, after the whole problem could have been avoided if you'd have just listened to them in the first place - So, what are we paying you for?"
