dsinc writes "Wired's Spencer Ackerman voluntarily subjected himself to what the U.S. military calls the Active Denial System, an energy weapon commonly known as the 'Pain Ray' that turns electricity into millimeter wave radio frequency and blasts targets with heat. He describes it thus: 'When the signal goes out over radio to shoot me, there’s no warning — no flash, no smell, no sound, no round. Suddenly my chest and neck feel like they’ve been exposed to a blast furnace, with a sting thrown in for good measure. I’m getting blasted with 12 joules of energy per square centimeter, in a fairly concentrated blast diameter. I last maybe two seconds of curiosity before my body takes the controls and yanks me out of the way of the beam.'"
The device has been tested now on over 11,000 people, with only two serious injuries to show for it. However, the device has limitations: rainy weather decreases its effectiveness, and its "boot-up" time is 16 hours, making it useless for breaking up unexpected, impromptu mobs.Read Replies (0)

On March 2, 2012, Timothy wrote about University of Michigan Professor J. Alex Halderman and his contention that there is no way to have secure voting over the Internet
using current technology. In this video, Alex explains what he meant and tells us about an experiment (that some might call a prank) he and his students did back in 2010, when they (legally) hacked a Washington D.C. online voting pilot project
. This is, of course, a "professional driver on closed course; do not attempt" kind of thing. If you mess with voting software without
permission, you might suddenly find the FBI coming through your door at 4 a.m., so please don't do it.Read Replies (0)

An anonymous reader writes "While living in Paris, Ben Franklin was struck by how many hours of daylight were being wasted to sleep during the summer months. He wrote an open letter to a Parisian journal lamenting the wasted expenditures on candlewax, and presented his back-of-the-quillpad estimates of the cost savings if the entire population arose an hour or two earlier. However, Franklin did not specifically mention moving the clocks ahead; instead, he suggested official means for enforcement (rationing the sale of candlewax to families) and encouragement (ringing church bells at sunrise). The clock-shifting technique which we know and love was credited to the New Zealander George Vernon Hudson, who proposed it in 1895. DST was first widely adopted by warring countries during World War I as a way of conserving coal needed for military purposes. This launched a debate over DST's usefulness that continues to the present day (particularly by people stumbling about in their bathrooms). Of course, Franklin is also associated with other questionable ideas, including bifocals, lightning rods, electric current flowing from the positive to negative terminal, leaking official documents to fan opposition, and an independent United States of America."
