The O'Reilly Open Source Convention is where coders, sysadmins, entrepreneurs, and business people working in free and open source software gather to share ideas, discover code, and find solutions. At OSCON 2005, more than 2,400 attendees took part in 241 sessions and tutorials across eleven technology tracks, learning about the newest features and versions from creators and experts. A record number of products launches and announcements were made, and sponsors and exhibitors from a wide range of companies filled the largest exhibit hall in OSCON's history. We anticipate that OSCON 2006 will be even more successful, and continue to be the place for the open source community to meet up, debate, make deals, and connect face to face. OSCON 2006 will take place at the Oregon Convention Center in Portland, Oregon July 24-28, 2006.
