An annual conference and exhibit for the Denver Metro area. Features an exhibit hall with many vendors (past vendors have included IBM, SGI, Tummy.com, Compaq, LWN.net, as well as Linux Journal, Linux Magazine, and the Debian project.

The best part of course is the BOF sessions, which highlight emerging technologies and companies and allow users to meet others with similar interests and talk to some of the thought leaders in that area. Some of the better sessions I've seen there have been Zope, security, Jabber, Java on Linux, and enterprise storage.

The main conference room has speakers doing their thing, past presenters have included Jon "Maddog" Hall, and people from Loki Games, Linux In Education, Debian, and embedded linux companies.
