Holy cow. I am sitting here in the general session hall. It is like a freaking aeroplane hangar. The projection wall is a 16:9 plus to 4:3 screen of massive size. I have no idea how many people are here, but there must be thousands. This is huge. I am sitting beside another Ubuntu user here as well and found out about wifi radar. Just what I was looking for. Stay tuned for more about the general session later.
