dryriver writes: CNN reports: Police find an advert for paid sex online. Its an illegally trafficked underage girl posing provocatively in a Hotel room. But police doesn't know where this hotel room is — what city, what neighborhood, what hotel or hotel room. This is where the TraffickCam phone app comes in. When you are staying at a hotel, you take pictures of your room with it. The app logs the GPS data (location of the hotel) and also analyzes what is in the picture — the furniture, bedsheets, carpet and other visual features. This makes the hotel room identifiable. Now when Police come across a sex trafficking picture online, there is a database of images that may reveal which hotel room the picture was taken in. About 100,000 people have downloaded TraffickCam so far.
Programmers used to batch environments may find it hard to live without
giant listings; we would find it hard to use them.
