"Leopard started out with a generous share of first-version glitches, but almost all of them have now been resolved by the second of two automated updates, which brings Leopard up to version 10.5.2. Finally, Leopard is extravagantly overdressed for the jobs that it's designed to do, and its pervasive eye-candy starts out looking dazzling but soon becomes distracting. Fortunately, from the beginning, the OS started out with options that let you put it on a low-eye-sugar diet, and the latest update has even more."

Ars has reviewed the new Mac Pro. "The performance of Harpertown and Stoakley is more evidence that Intel is doing right by Apple, and this eight-core monster is a worthy successor to the Mac Pro name. At USD 3599, it's expensive; the USD 800 cheaper 2.8GHz model will likely be adequate for the majority of users. But if you want maximum performance and a machine that's unlikely to show its age anytime soon, the Mac Pro is a good buy."

"Although I have some doubts that XFCE is 'so very much lighter' than GNOME (GNOME 2.20 doesn't take too much memory if you don't start all kind of crap), it is still lighter, and in a few years there will be less and less antiquated computers who require extra-light window managers (Fluxbox, Openbox, Blackbox, WindowMaker, IceWM). XFCE is reasonably mature, and constantly improving, so it has all the chances to become the mid-weighted Desktop Environment of choice pretty soon! What is XFCE needing to reach the Nirvana? Here's the way I see things."

Role-based access control is a general security model that simplifies administration by assigning roles to users and then assigning permissions to those roles. Learn how RBAC in SELinux acts as a layer of abstraction between the user and the underlying TE model, and how the three pieces of an SELinux context (policy, kernel, and userspace) work together to enforce the RBAC and tie Linux users into the TE policy.

"KDE 4 is seen by many to be the next big step on the free software desktop, while others think releasing 4.0 in its current condition was misleading and a mistake. Either way, it's an innovative release and inline with Fedora's goal of providing the latest and greatest free software it is set to be the default KDE environment in the next major release of Fedora. We caught up with two members of the KDE SIG to talk about the work they're doing to get it ready for release, their own opinions on the software and what they think about the progress made by Fedora in getting over its GNOME centric reputation."
