The LinuxWorld Expo in San Francisco is the center of the Linux universe this week, celebrating the best Linux apps and advancing the cause of Linux in business. If you can’t be at the Moscone Center, you can read the latest conference news at the LinuxWorld Expo web site, which naturally is powered by … Windows Server 2003.
Linux enthusiasts are not alone in finding their “World” running on Microsoft software, as the Mac World Expo is also hosted on Windows Server 2003.
