I just returned from a week in London for the 4th annual 44CON. I had an amazing time hosting a quiz, being on panel and giving a talk.
44CON is one of the best ran conferences that I attend. Adrian and Steve both really care about the conference and it being entertaining and educational for the attendees. 44CON (like Derbycon) has figured out how to make the conference feel like a meeting of old friends and not a sales pitch or exhibitor expo.
My friend Dan Raywood has a bunch of good write ups on his IT Security Guru site about some of the talks. You will want to check out his stories about running Doom on a hacked printer and wiping data from Android tablets.
Some other highlights were the converted red bus bar:
the amazing DJ they had on Thursday night:
and the badges:
As you are thinking about your training budget next year make sure you include a trip to London in September!
