Today I give a talk at my university about data protection using cryptographic techniques in Linux. It was a good talk, there was around 30 people in the room.
The talk was recorded entirely so I plan to have a digital copy of me very soon :) I will post the slides on another post, as soon as they are uploaded to a stable server.

*[UPDATE 2]: The slides moved to another server. Get your copy here. Have fun :-)
