The Architecture SIG is a round table discussion where senior developers and architects take turns presenting on enterprise architecture topics to the group. Because of the format participation is expected of all attendees. This is great place to get feedback on a design direction or to tell everyone about a cool trick you discovered. Topics range from design patterns, to inter-process communications, refactoring and agile practices. Bring your laptops so that you can show off that new piece of code you have just written, or participate in the language debates. The meeting is divided into three rounds: Current problems, Technology discussion, and a Show me something cool. Each round generally lasts about 45 minutes to an hour. Participation in the show me something cool round is required.
