Once upon a time, using open-source servers and applications for business was frowned upon in many circles. Today, you'd be hard pressed to find any sizeable infrastructure that doesn't leverage open-source code in some form or another, be it a few MySQL databases, Apache on the Web servers, or a pile of Perl, PHP, Ruby, or Python applications holding things together.

Although Nautilus—the GNOME file manager—includes many useful features and offers an excellent implementation of the spatial paradigm, its browser mode is less impressive and is missing some must-have functionality. The Nautilus developers are about to deliver a big improvement, however, with the addition of full support for tabbed browsing.

Thin client computers are stripped-down desktops that run many of their functions by connecting to a centralized server. Enterprises and other organizations often find them attractive for both convenience and cost. They're also particularly suited for using Linux-based operating systems and applications.

Six degrees of freedom (6DOF) devices allow for movement in three axes, tilt in two axes, and rotation in the third. Some of these devices look like small joysticks -- for example, the SpaceNavigator. These devices are typically used for computer-aided design and manufacturing (CAD/CAM) and other 3-D applications. With a new programming library, you can now also use them with Linux applications.

Live CDs do a great job of advertising Linux distributions. In addition to general-purpose live CD distributions, there are lots of task-oriented live CDs. Wouldn’t it be great if you could carry multiple live CDs on one DVD disc? Nautopia.net has put up a script that you can use to make a custom DVD to boot multiple live CDs.

Recently, Novell Inc. has been the beneficiary of generally good news. First, Microsoft gave Novell the nod to write open source extensions to its new System Center, which signals Microsoft’s move toward greater interoperability. This will benefit all open source vendors, but Novell in particular, because these extensions are built on Novell’s ZENworks management software.

"The Linux kernel (the core of the Linux operating system) The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc."
