During the workshop I'm going to create and setup a web server (Debian Squeeze) from scratch.The main goal is to make it use RAM less as possible, however make it fast and secure. I will introduce the basic tips and tricks on configuring Nginx, PHP (spawn-fcgi), MySQL, MongoDB, Ruby (rvm), Rails (unicorn), Subversion (with SASL auth), Postfix, IPTables and will try to answer all your questions
