Like every year since 2004, this year I attended Fosdem. Like last year Fosdem was half work half fun - It's half work because I represent Mozillamessaging. I gave a talk, and the content of the talk is nicely summarized by my boss in his Thunderbird in 2010 blog post.
Then I gave a lightning talk on how to create a PGP key and sign emails - as I think signing emails is a nice feature that helps protect your identity - this was done in 5 minutes and I even made the audience laugh , when I started to generate random data by typing on the keyboard as I was running against time.
As usual I spent most of my time with Patrick the author of the enigmail add-on, and spend a lot of time in the mozilla room. I did go to some of the lightning talks (one was on certificates, the other on yet another linux distribution). I missed the very good talk about evil on the internet - but watched it since on youtube, a very interesting talk about fishing and how it works.
I attended the pgp signing party and got cold - next year I'll make sure to take my coat when attending the party:-). Of course I took many pictures around 146 but only kept only 17 to display. I met quite a few interesting people and had many interesting conversations - so on that social side it was very interesting. Plus I saw many ex-collegues and that was fun.
