modi123 asks: "It's getting close to the middle of the year and I am looking for a developer conference or two, so that I can fill my educational quota. TechEd in Orlando is out (I was the last yell 'not it' and I have to remain behind to man the system), my boss won't allow me to travel to TechEd Euro in Barcelona, and I am at a loss on where to go. My areas of expertise are VB.NET, MSSQL, and application development, while I dabble in AI, info sec, and GUI development. Do you have any suggestions where I can go? Side note, I keep hearing about this 'defcon' thing — would that benefit an app developer, or is that mainly an overblown info sec experience?"
