I've finally had a chance to record myself giving my presentation for FOSDEM tomorrow. I can listen to this a few times this afternoon, and polish it.
I always make sure that I prepare to give a shorter presentation than my full timeslot, since, in my experience, there is nearly always some kind of delay in getting started, or running behind schedule etc. Plus, to allow time for questions.
But perhaps I have been *too* generous in keeping in short here, as it only runs for 12 minutes at the moment...
