This tutorial shows how to combine four single storage servers (running Ubuntu 11.10) to one large storage server (distributed storage) with GlusterFS.

This guide explains how you can configure DNSSEC on BIND9 on Debian Squeeze and Ubuntu 11.10.

Fedora 17 GNOME beta, as well as the beta of the KDE, LXDE and Xfce Spins, were released yesterday – almost two weeks past due date. This, however, is not highly unusual for the Fedora project. Unlike Ubuntu, their release schedule is not cast in concrete. They are more interested in getting stuff that works out the door, instead of shoving something out to meet a set deadline.
