Remus provides transparent, comprehensive high availability to ordinary virtual machines running on the Xen virtual machine monitor. It does this by maintaining a completely up-to-date copy of a running VM on a backup server, which automatically activates if the primary server fails. - Matteo Marchelli

Howdy there! This is my collection of notes that I have collected over the years as a Sys Admin. I am sharing them here hoping that they will be useful to you. These are concise notes to refresh your mind on how to do certain things, maybe you know what need to be done on one platform but don't know the commands on another. Or maybe just pointers for you to read up the relevan man pages or know what to google for :) They are work in progress, I know I need to polish up my notes so that other can make sense of them. As time permits... - Matteo Marchelli

Do you hate when you (as a system administrator or tech support) get a call from somebody from your office, with question: “What’s wrong with my PC? Come here and fix it!”? I’m sure you do. And most of the problems can be solved easily by users themselves, without the need for you intervention. But it seems they just like to call you. There is a solution for your problem. - Matteo Marchelli

I wrote a Ruby beautifier script a few years ago and it has become very popular. I decided to rework it to beautify Bash scripts, even though I realized that Bash shell scripts are much more free-form than Ruby programs. This project is the result — a Bash script beautifier written in Ruby. I have tested the script on a lot of typical Linx scripts, both my own and from the system. While testing I have reluctantly come to the conclusion that there are too many perverse ways people write Bash scripts for this program to ever correctly beautify 100% of submitted scripts. Maybe 99%, but never 100%. - Matteo Marchelli

Disk2vhd is a utility that creates VHD (Virtual Hard Disk - Microsoft’s Virtual Machine disk format) versions of physical disks for use in Microsoft Virtual PC or Microsoft Hyper-V virtual machines (VMs). The difference between Disk2vhd and other physical-to-virtual tools is that you can run Disk2vhd on a system that’s online. Disk2vhd uses Windows’ Volume Snapshot capability, introduced in Windows XP, to create consistent point-in-time snapshots of the volumes you want to include in a conversion. You can even have Disk2vhd create the VHDs on local volumes, even ones being converted (though performance is better when the VHD is on a disk different than ones being converted). - Matteo Marchelli

I tecnici sono riusciti prontamente ad eliminare le macchine windows infette con altre linux che venivano utilizzate per lo sviluppo evitando che il contagio potesse diffondersi. La rete viene tenuta in piedi da macchine Solaris con gli operatori che ci collegavano da remoto usando X su macchine windows. - Matteo Marchelli

Il progetto Bio-Linux nasce da una divisione del NERC (National Environment Research Council) nel Regno Unito che si occupa della materia in oggetto. L’NEBC ha coraggiosamente preso in mano questo insieme variegato e disperso di software per la bioinfomatica e l’ha raccolto in un unico repository e poi è andato oltre, creando una distribuzione GNU/Linux a tutti gli effetti, basandosi sul “core” di Ubuntu (scelto nella sua versione 8.04 con supporto a lungo termine). - Matteo Marchelli
