It is nice to download the course materials from coursera.org and view them offline especially the mp4 video lectures. Here is a nice utility which exactly does that. I used this script to download video lectures for Functional Programming Principles in Scala course. It comes handy to listen from smartphone!
git clone https://github.com/jplehmann/coursera
cd coursera
