The code for the examples I showed during Lecture 16 is now available. Just a reminder: the ProjectEPICFilters code will not work on your machine due to the fact that the "epic-vm2" host is a research machine that is not publicly available. Consider that code a template in which you can change the URL to some other web service that provides JSON (see developer.twitter.com for examples) and then modify the JSON parsing code to make the code work for some other web service.
