Time ago, while I was playing with the CMS I use for this site, I had to completely rebuild a Linux virtual guest dedicated to a mail server based on qmail. And I realized that the time had come to reorganize my old notes in a web space.
Web programming and web server administration have quickly become my favorite "sport" (ask my wife!) as well as an occasional job opportunity, even though my main activity is teaching in an high school here in Cagliari. Everything I know in this field is due to Google and to people who share their knowledge and their products for free. This is my attempt to give something back to the Open Source community.
