As Matt Asay notes today, plans for the Linux Foundation's LinuxCon conference in Portland Oregon, September 21st to 23rd, are firmed up. The event has an impressive roster of sponsors, including Hewlett-Packard, IBM, Novell, and Intel. The lineup of speakers also looks very notable, including Linus Torvalds, Mark Shuttleworth, IBM's Bob Sutor, OpenSUSE Community Manager Joe Zonker Brockmeier, HP's BDale Garbee, and Matt Asay from Alfresco Software. Until June 1st--just a few days away--you can register for the event for $299.
