On January 22 2011 I was contacted by Mirko Urru for his thesis and on June 24 at 14:30 we were together to present his work at EuroPython: a very nice experience!
On May 9th 2009 at 12:20 I was going to present some techniques to scratch data from the web in front of a classroom full of people interested in this subject: it was really a great experience!
