Course on free software servers architecture - First session - Presentation - Intro to free software - Free software and system administration

On 25th of March of 2011 was the first session of the course on free software servers architecture by libresoft. I took the decision to participate to deepen my knowledge about webservers and all the parts that are still a mistery to me. I want to learn more server administration tasks using exclusively free software. I don't usually take non-free options into consideration when choosing software but in the field of servers free software is also the most popular.
