Barettas are neat, but 45s are more lethal. But why bother with a side-arm? Go straight to the MP-5 and hollow point bullets.
3-round burst + hollow point bullets = you without a face man I'm demented
But, if you want a hacker school, do a computer science/C++ course. If it's a "disfunctional parent's guide to computers" get out! Go for C++. I'm in a technical, computer science school, so I'm going to learn C++. Plus, I'm mentoring under a hacker at school (he's good), so I'm set, learning-wise. Maybe you need a hacker mentor.
