One of the more recent really cool tech events to hit the Twin Cities is the Twin Cities Code Camp. They happen usually every 6 months and #3 is occurring at the end of the month on October 27th. Code Camp is organized by Jason Bock, a Microsoft MVP and a good friend of mine from Magenic Technologies. It is sponsored by a number of area technology businesses including Magenic, Microsoft and New Horizons, which is where its held.
The event is free to attend (plus they feed you breakfast and lunch). You get to choose from a number of sessions where you can learn about new technologies and chum with a lot of really smart people.
Also, I've been given the privilege to present one of these sessions. I'll be talking about LINQ to XML, Microsoft's new XML API. If you're interested in LINQ (which you really should be since its the main feature add for the next version of .NET), there are two others sessions before mine that talk about LINQ to SQL and LINQ to objects. Very cool stuff! Check out the schedule to see all the topics.
