Netflix Speed

Ever wonder how Netflix gets you your DVDs so fast? (Of course you have.) Well, they gave a journalist at the Chicago Tribune a sneak peak. Amongst the amazingness:
From there [manual sorting by employees, many of which are grandparents], action shifts to long machines that go ffft. This, right here, is how you get discs as fast as you do. Inspected discs are scanned into the inventory by a machine that reads 30,000 bar codes an hour -- ffft, ffft, ffft. The moment this machine reads the bar code, you receive an e-mail letting you know that your disc arrived. Then discs are scanned a second time -- if a title is requested, and around 95 percent of titles get rented at least once every 90 days, the machine separates it and sorts it out by ZIP code. (The entire inventory of the building is run through this daily, a process that alerts other warehouses of the location of every one of the 89 million discs owned by Netflix.) After that, separated discs are taken to a machine called a Stuffer -- which goes ssssht-click, ssssht-click -- and stuffed in an envelope, which is sealed and labeled by a laser that goes zzzt.
Oh, and every 65 minutes they do calisthenics.
