AP CS No Longer Counts For High School Graduation in Georgia (for Now)

Georgia used to count AP CS as a fourth "science" class towards high school graduation. As of 1 October 2009, that is no longer true.

Collective Intelligence: a Fad or Real Research?

A recent trend in HCI research is the extension of the long time goal of augmenting human intelligence to "augmenting social intelligence." That is, enabling not just a single person to find and make sense of information, but enabling a group of people (whether explicitly or implicitly organized) to make sense of information.
