The above link goes to a podcast of an NPR story I just heard. Fascinating stuff -- in short, it's an interview with an architect about security in big cities given recent attacks. What's it got to do with analytics? At one point, the architect discussed how they can use machines to monitor an area, and things like unusual sound patterns, movement patterns, etc. can be detected and can set off alerts for people to check. Pretty cool, huh?
