Earlier today I gave a presentation at the Technical University Berlin about things you need to know, things you should expect and things you shouldn't expect when your are aspiring to become a successful Free Software Hacker.
I have put my slides up on Google Docs in case you are interested, either because you are the target audience (i.e. a university student) or because you need inspiration for a similar talk about the same topic.
The first two slides are in German language, so skip over them. The interesting bits are all in English. I hope it's quite comprehensive (though of course terse). Enjoy:
In case your feed reader/planet messes this up, here's the non-embedded version.
Oh, and thanks to everybody who reviewed and suggested additions to the the slides on +.
