Deep drawing is a process that very efficiently produces a "net shape" part. Apple could have just chucked a giant hunk of aluminum in a lathe and created the same part, but that amount of metal removal is extremely inefficient. Deep drawing efficiently creates a hunk of metal that is very close to the final shape of a Mac Pro in just a couple of operations.

There is a button to vote a straight Republican ticket, and when pushed, it voted a straight Democrat ticket. A local voter observed this behavior four times in a row; the fifth time, the button worked correctly. If ATMs were this unreliable, no bank would use them. Why is this level of failure acceptable in voting machines?

Sensors monitor the levels of deposited dust on the panel. When the dust levels get too high, a charge is applied to the coating and the dust is physically move across the panel via the charge and dumped off the edges.
The procedure uses a minimal amount of energy, making it a viable cleaning solution. It removes 90 percent of dust, greatly improving power output. And best of all, the technology has already been stress tested by NASA space probes and rovers under the harsh Martian climate."

It was surprisingly hard to find the actual deal on the Best Buy web site, but with some digging I found: http://www.bestbuy.com/windows7pc and click on "PC Home Makeover".
steveha writes: We've seen stories about bogus Craig's List postings. It happened again and this time, it was an attempt by burglars to cover their tracks. A police officer said "Other Craigslist hoaxes we've seen were malicious..." which begs the question: how often does this sort of thing happen? Is this new, or has anyone ever pulled this sort of stunt with, say, a classified ad in a newspaper? Are people more inclined to believe one of these hoaxes if they read it on the Intarweb?

His blog tells the story of how he tried an unconventional treatment and how well the treament worked for him, with lots more details on Spasmodic Dysphonia and how to treat it. Extremely interesting reading.
