This is an experimental site I use for learning. I'm a grad student in the department of computer science at the University of Oxford; my thesis is about how computer security testers co-operate with other security testers in different organisations (or countries, or security classification levels) whom they can't talk to directly for fear of violating security rules. Cross domain systems are like that. For information on why this file exists, see http://humanstxt.org/ and if you want to find me, try email to joe.loughry@stx.ox.ac.uk.
