Few will dispute that Linux came of age in the past year. As in the past, enthusiasts have continued to load Linux on their PCs and laptops and hack software in their basements and on unused portions of systems at their jobs. More recently, however, traditional software companies have begun porting products and programs to Linux, and the operating system has made even deeper advances in the Web server market, as well as in supercomputing clusters and application server environments. But despite all this progress, the idea of a truly open-standard platform for mission critical needs in the enterprise remains a hot debate. There are many who believe that the community needs the kind of strong, centralized support system for innovation and development that traditional proprietary software has long enjoyed.
