For the first week of March, 2008, the tutorial of the week is the encyclopedic "Installing Kubuntu 7.10 on Software RAID5" by LNK.
This is a howto on an immense scale, beautifully arranged and cataloged to the tiniest detail. Even if you don't work with this hardware configuration, it's worth skimming this tutorial just to admire its presentation. Well done.
See you next week!
