Consumers may not soon replace Windows with Linux on home PCs, but theres plenty of evidence that Linux is challenging Windows in many other client environments. Greenblatt, for example, used a Linux-based Sharp Electronics Corp. Zaurus 5600 PDA to run much of his LinuxWorld keynote presentation. Meanwhile, automaker DaimlerChrysler Corp. is working on a Linux-based management and navigation system for its cars. "DaimlerChrysler recently demonstrated an S-class Mercedes equipped with Universal Mobile Telecommunications System services in Berlin. Applications demonstrated included radio, navigation, maintenance services, Internet access [including e-mail and Web browsing], an MP3 player, and games. Computer Associates is working with DaimlerChyrlser on the management," Greenblatt said."And all of those resources that were spent making 2.4 ready for the enterprise will be freed up once 2.6 is available, and [they will] be able to start working on the next set of things. As Red Hat [Inc.] and [Novell Inc.s] SuSE [Linux] both release 2.6 kernels, there will still be room for them to add new features that make it more robust," Dargo said. "This is an exciting time for all of us, and there is a sense of purpose, destiny and challenge among us all." Indeed, large enterprises continue to invest in Linux where it performs beston the server. The Weather Channel Enterprises Inc., in Atlanta, a longtime Linux shop, recently refreshed its server technology with 110 Dell Inc. PowerEdge servers running SuSE Linux. The upgrades allowed Weather. com to improve the reliability and speed of data to its customers during severe blizzards in December. The site served more than 34 million page views in one daymost of them dynamically generatedat an average response time of 1.31 seconds. "Whether our customers are experiencing severe weather, planning a vacation or just trying to decide when to play a round of golf, theyve come to depend on the information we provide," said Dan Agronow, vice president of technology at Weather.com. "[The Linux servers] will help us continue to be one of the most reliable and popular sources of weather information on the Web." Others, such as Red Hats Paul Cormier, in Westford, Mass., cautioned the recently released Linux 2.6 production kernel is not quite ready for the enterprise and said its implementation into shipping distributions could be a year away. But looking at the future, Cormier is bullish, saying on the server side it was "like a freight train moving."
Dave Dargo, vice president of Oracle Corp.s Linux Program Office, in Redwood Shores, Calif., said he believes Linux is on the verge of achieving mass-market enterprise capability. The 2.6 kernel was a great catalyst for the consolidation of many changes made after the production 2.4 kernel was released, Dargo said, so a lot of the work that was done in the 2.4 kernel around enterprise scalability, reliability and stability is now part of the 2.6 kernel.
