Extract Windows serial number from BIOS

Recently I needed to reinstall Windows on a system and, unfortunately, I had lost the serial number. Using two simple Linux bash commands, I managed to find the serial number embedded into the computer’s BIOS.

Backup & versioning with RSYNC

You may already know rsync – the powerful tool which you use to synchronize files from one location to another. I am using it on every Linux server that needs scheduled backups, but this time I had to not only backup some files, but also to keep track of previous versions, due to users being sloppy with their work and sometimes it happened they have permanently deleted the files, without moving to Trash. (sigh!)

The following line of code may be saved in a file, as backupversion.sh to a folder of your choice (let’s say /root/backupversion.sh).

Two WordPress tweaks

I have been searching for a way to make my personal blog more user friendly. In fact, this is what I keep doing, searching for better ways to tweak my WordPress blog.

Matrox G550 dual monitor

Sometimes Google is just not enough. Especially when you’ve clicked hundreds of results, hoping you will find the right answer to your problem. My problem was the Matrox G550 video card and its missing drivers for the modern, nowadays versions of Linux. In my case, the distro is Ubuntu.

I have tried to do everything I found on Google about how to set up X in order to display on dual monitor configuration. After hours of trying almost everything, I have combined all information I found and managed to find the workaround for Matrox G550 dual monitor configuration.
