I made it, through the full-body scanner and a flight above the clouds, to Washington D.C. I mixed Metro (mostly) and walking (from L'Enfant Plaza across the National Mall to Chinatown, so get a sniff of the air, get a look at the monumental-ness, and grab some tasty Thai food) to get me to the University of Maryland, where I'm staying and taking a course on disclosure control. Today was the ins and outs of releasing aggregated data, which is the end of things I've worked more in. Mostly for myself: I should e-mail Dr. Cox about where methodological transparency grants the intruder extra leverage in estimating sensitive cells: his problematic findings on feasible intervals, and Dr. Karr's recent conference papers on the topic in general. I think I'm getting some good review and some connecting details that I was missing so far.
Tonight I'm probably going to drop south from Foggy Bottom into the western end of the National Mall and try to see the giant statue of Lincoln and the Vietnam Veterans' monument. Tomorrow: microdata, dynamic queries, and then the rush to the airport to get home.
