The most recent "hack" I've done is to GradeQuick, a software used by schools to digitalize grades, attendances, etc. Teachers using the software input the grades, assignments, etc and GradeQuick does all the behind the scenes calculations.

I'm currently working on an easy to use Java application that will take care of the unlocking/locking process, but it's a relatively simple thing to do by hand.

Speaking of school-related hacking, I've gotten control of the highest network privileges that one could get on my network, and have created a backup admin account that I use whenever I need to access people's personal folders or whatever ^_^.

Our school allowed full (besides porn of course) access to the web for all teachers. I've recovered a few teachers username/passwords so I've basically got unrestricted access to the interwebs.

And that's about it… If you'd like more information about my GradeQuick unlocker, I'll be posting betas and that up at: http://steverolfe.com/blog/ (which is brand new as of a few days ago).
