Ever wish you had a place to let your Linux applications play -- where they wouldn't hurt anything else? Do your killer apps spend too much time killing each other? Originally conceived as a kernel developer's tool, UML lets you set up multiple virtual machines that are isolated from each other and from the hardware. Now, you can test applications all the way to failure without breaking the host system -- or even requiring a reboot.

For almost every technology company, business is a bit slow at the moment.
Apart, that is, for companies involved with Linux, the open source operating system.
Many firms that sell software and services based around the free operating system are doing good business and many large firms and governments are eagerly adopting the software.
Even Microsoft, traditionally the arch-enemy of open source advocates, has started espousing some of the philosophy that drives the movement.
This article takes a look at cat -- the command that UNIX lovers love to love, and UNIX haters love to hate. Cat is useful when you need to process several files as one and save the results of such processing to a single output file. The cat (short for "concatenate") command takes one or more files on its input and prints them to its output as a single file. For example, cat chapter01 chapter02 chapter03 > book saves three chapterXX files into a single book file.

Don't be to upset because you couldn't get your boss to send you to the LinuxWorld conference in NY this week. You can still get the free IBM Linux Software Evaluation Kit that's being handed out there to Linux developers. Its been expanded to 4 CDs for 2003. In addition to the newest levels of DB2 Universal Database, WebSphere Application Server, and Lotus Domino, the 2003 SEK will also include WebSphere Studio Site Developer, WebSphere MQ, Tivoli Access Manager, Linux porting tools, white papers and tutorials.

Until a few years ago, the Top 500 list of supercomputers was dominated by proprietary solutions with prices that put high-performance computing (HPC) out of reach for all but the most well-funded institutions and companies.
The first step in improving Linux performance is quantifying it, but how exactly do you quantify performance for Linux or for comparable systems? In this article, members of the IBM Linux Technology Center share their expertise as they describe how they ran several benchmark tests on the Linux 2.4 and 2.5 kernels late last year. The benchmarks provide coverage for a diverse set of workloads, including Web serving, database, and file serving.

Linux will emerge as the dominant operating system in corporate data centers, according to a new study by Goldman Sachs (NYSE: GS).
According to the study, IT buyers will use Linux to take advantage of lower-cost, higher-performance Intel-based servers -- and to avoid "premium-priced proprietary systems." Eventually, systems running Linux will displace systems based on Unix and RISC processors.
