Red Hat and Novell, the two top Linux sellers, have only just begun building Xen virtualization software into their products. But they're already planning to add a higher-level option.

Perl and PHP are two widely used languages for building dynamic Web sites. They make up two thirds of the "P" in the Linux, Apache, MySQL, Perl/PHP/Python (LAMP) stack. How does their performance, using mod_perl and mod_php, compare for everyday Web programming? I attempted to find out.

Examine methods for standardizing your interface to simplify movements between different UNIX systems. If you manage multiple UNIX systems then the hardest task can be switching between the different environments and performing the different tasks while having to consider all of the differences between the systems. This article looks at ways that can provide compatible layers, or wrappers, to support a consistent environment.

In the SoC design for hardware acceleration series, author Sam Siewert migrates a simple C function to a SystemC specification that can be simulated and verified for ultimate implementation as a hardware function. Part 1 provided the C code and a general overview of video capture, streaming, and processing. Part 2 shows how hardware acceleration of emergent applications can benefit from SoC design and reconfigurable SoCs with hybrid C software and field-programmable gate array (FPGA)-based functionality.

Bernard Golden has posted a summary of his LinuxWorld session calledOpen Source Goes Vertical where he talks about the results of his LinuxWorld session. His session discussed the market for open source healthcare software and included several luminaries including our own, Will Ross.

Microsoft has promised to help Firefox and Thunderbird coders get their open source programs working on Vista. The head of Microsoft's open source software lab Sam Ramji said that Vole had approached Mozilla to if it's interested in making sure the Firefox browser and Thunderbird e-mail client run under Windows Vista.

With Vista, Microsoft is taking much greater control over key aspects of the way users' computers run - especially when it comes to security. This will highlight the differences between the closed development model advocated by Microsoft and the approach taken by free and open source software developers like the people behind GNU/Linux or the Firefox browser.

Black Duck announced that it has significantly expanded the KnowledgeBase of its protexIP platform. The company has added more than 30 million software component signatures ("Code Prints") from more than 1,000 software vendors. With this addition, protexIP allows users to identify and track the reuse of commercial software components, helping them ensure compliance with their licensing and royalty obligations.

People were constantly asking why Red Hat -- the name that's practically synonymous with Linux -- wasn't at San Francisco's recent LinuxWorld megashow. Now, we know.

AppArmor is a product that Novell acquired when they bought the company Immunix in May 2005. It provides an interesting alternative to traditional security measures. AppArmor works by profiling the applications that it is protecting. A profile records the files that an application needs to access, and the capabilities it needs to exercise, during normal, "good" operation.

Levanta announced the launch of their North American Partner Plus+ channel program, creating exciting revenue opportunities for resellers and systems integrators with Levanta's award-winning Intrepid M Linux management appliance.

Tired of old VNC? Give NoMachine's NX system a try for impressive remote desktop action.

The Proliferation Committee of the Open Source Initiative (OSI) has published the first draft of a report that seeks to curb the proliferation of open source licences.

Lenovo and Novell have jointly announced a line of Linux-based ThinkPad mobile workstations that run the SUSE Linux Enterprise Desktop 10 operating system.

Building on the success of its school computer laboratory project, the tuXlabs project team has formed a company, backed by the Shuttleworth Foundation, to continue supporting schools and look for new opportunities using its Linux experience.

New Delhi: Nucleus Software, a provider of software solutions for the banking and financial services industry, has joined Red Hat's Independent Software Vendor (ISV) partner ecosystem.

While at LinuxWorld, I was contemplating how IBM's multi-billion dollar investment in free software has born fruit in the form of their hard sought after two inch rubber tux, when I met up with Robin Miller who interviewed me on the quality of this year's swag. Officially, this year's theme was mobile computing, although virtualization also predominated.

There are a lot of things that Linux users and developers say are good about Linux. But at least one notable Linux kernel developer sees plenty not to love. "I think the enterprise stable kernel model doesn't work," said Greg Kroah-Hartman, who works closely with Linus Torvalds and Andrew Morton, the keepers of the Linux kernel and its development.

Devicescape has renamed its WiFi client software stack, and added support for a "one-button" secure WiFi configuration standard. The Devicescape Agent, formerly "Secure Wireless Client," offers a standards-based "Easy Access" feature aimed at making secure WiFi network configuration trivial for "service-enabled" consumer electronics devices such as network-ready cameras and music-players.

Recently I needed to do some distance education; one of my coworkers wanted me to show him how to do software builds on Linux. The only problem was that I'm on the East Coast and he is on the West. How could I show him the build and install process? After considering some alternatives, we found our solution in GNU Screen.
