The second update to the 2009 branch of Pardus Linux features the latest version 4.4.4 release of the KDE desktop environment, an optimised package manager and a number of updates to the included packages

KDE 4 features a new desktop shell named Plasma. Part of Plasma is support for desktop widgets, known as "Plasmoids", which can include a clock, a notepad and more.

The latest series of the K Desktop Environment now utilizes Plasma, a new desktop and panel user interface tool that aims for a more functional, user-friendly, and sleek KDE desktop. Plasma also supports Dashboard-like widgets called plasmoids.If you want to further enhance the look of your KDE 4 desktop, I have here a list of some of the most beautiful Plasma themes available:

Mozilla Corp. yesterday patched 10 vulnerabilities, half of them marked "critical," in its open-source browser as it updated Firefox to Version 2.0.0.13.
