Guest Lecturer Raffi Krikorian talks about how Twitter works, and some of the technical challenges that they've had to overcome. This video is for the CS10 Summer 2011 Professional Development for High School teachers. Notes are available. This video was taped during our Fall 2010 AP CS : Principles Pilot semester. NOTE: Unfortunately, the video camera shut off near the end of his talk. His remaining slides, however, are shown at the end. Apologies!
