CS 798 Mathematical Foundations of Computer Networking, Fall 2008, University of Waterloo: http://blizzard.cs.uwaterloo.ca/keshav/mediawiki-1.4.7/index...
This is a really great course that covers a broad set of topics, and is some what similar in structure to the Stat 110 course. Beyond the basics of probability, you also can learn a good deal about statistical inference and stochastic processes.
This works on Ubuntu 11.10. There is a lot of quality content on ITunes and using Ubuntu as my main OS meant I couldn't access it. But this is awesome! I can finally download those lecture videos. Thank you!
