Getting Started
(How to get a PHD)
1) Configure the rails data_model project 2) Download a bunch of Phpinfo files using the collection tools (I have about 4 GIGs of phpinfo output, but they aren't in GIT) 3) Parse the php info files, and store them in a mysql database 4) use the rails website to browse the collected files, and the graph_analysis scripts to make sense of them 5) write a bunch of papers 6) celebrate!
Libraries You'll need
You probably need to install hpricot, and at least a few other ruby modules.
Good luck :-)
