Wolfram Alpha, the "computational knowledge engine" that quietly handles a large number of queries from Apple's Siri, launched a new feature today that allows you to quickly get an overview of all your data on Facebook. The new report, says Wolfram CEO Stephen Wolfram, expands Wolfram Alpha's "powers of analysis to give you all sorts of personal analytics." The company plans to expand these reports with new features over time, but they already give you a pretty deep look at your Facebook habits.

I am increasingly of the opinion that we don't have to find "the solution" to "this problem." The question of what students are learning and how they have created the work that they submit is one that is as old as teaching, and the change in technology in many respects introduces only an incremental change in how we must approach this. If we are to be effective as instructors we have to be thinking hard about what students know and how we know it, and these are not things that are dependent on technology.
