I decided to install Ubuntu 8.04 beta, and try to imagine myself as a novice desktop user and how this may be the replacement desktop for my mother, or my wife or sister (note: all my brothers are geeks so I can’t include them) or a small business.
Ubuntu has evolved over the last years, and has become quite popular on the desktop. Ubuntu is also working on its position in the enterprise. I, however, am a bit apprehensive to adopt Ubuntu for the server, and have a tough time recommending my clients to use Ubuntu vs. Red Hat (CentOS) or SuSE. I currently prefer CentOS for the free distribution, and RHEL where required (like SAP implementations).

Notably: autodiscovery (less manual configuration of new frontends), storage groups (no need for LVM/etc), support for multiple recordings on one DVB/ATSC multiplex, a couple new plugins, some new deinterlacing/video display options, and many, many other things.
I have recently been working virtualizing Windows and Linux machines using Xen. A few things popped up along the way and a bit of research was done to make things work properly, these are some of the notes I used along the way.
– I am partial to using LVM based devices for creating my virtual machines. Think lvm snapshots for backups.
I needed to find the peak utilization for over 100 Linux servers, so rather than interpreting sar output manually, I spent my time doing something that I could reuse.
I had a few systems crash over the weekend, and one in particular had some filesystem corruption. It also happened that the file corruption was on the root filesystem, and it was a SAN boot machine. Anyhow, after booting up into a rescue disk (using pxe boot), I was able to fsck the root filesystem.
