This month we bring you two great desktop distributions: Mageia 3, from the all-volunteer community that forked the commercial Mandriva Linux distribution, and Linux Mint Debian, a semi-rolling distribution based on Debian Testing.

The GNU project hasn't given up on the venerable Hurd project, and this long-running GNU Free OS project has recently received a burst of new energy with the release of a new Debian port.

"maddog" and Linaro are collaborating on a contest to improve the performance of certain GNU/Linux source code modules.

The DVD attached to this issue brings you two great new distros: Knoppix 7.2 and Fedora 19.

• Considered by some to be the “Best Live Distro on Earth,” Knoppix is the ultimate sys admin tool – a full-featured system packed with troubleshooting apps that boots and runs from the DVD drive.
• The Red Hat-sponsored Fedora is a free Linux with many of the same tools and packages found in Red Hat's enterprise editions.

The DVD attached to this issue brings you a pair of the world’s most popular Linux distributions. Mint 15 “Olivia” is the latest release from the ever-friendly Linux Mint, a desktop distro based on Debian and Ubuntu that keeps the emphasis on simplicity and ease of use. Mint tops the DistroWatch downloads list and describes itself as: “The 4th most popular home operating system after Microsoft Windows, Apple Mac OS, and Canonical’s Ubuntu.”
