"In the Harry Potter world, Ravenclaws are known for being the smart ones. That's their thing. In fact, that was really all they were known for. In the books, each house could be boiled down to one or two words: Gryffindors are brave, Ravenclaws are smart, Slytherins are evil and/or racist, and Hufflepuffs are pathetic loyal. (Giving rise to this hilarious Second City mockery.)"

"Businesses invest billions of dollars annually in market research studies developing and testing new ideas by asking consumers questions they simply can't answer. Asking consumers what they want, or why they do what they do, is like asking the political affiliation of a tuna fish sandwich. That's because neuroscience is now telling us that consumers, i.e., humans, make the vast majority of their decisions unconsciously. Steve Jobs didn't believe in market research. When a reporter once asked him how much research he conducted to develop the iPad, he quipped, "None. It isn't the consumers' job to know what they want." And according to some measures, the iPad became the most successful consumer product launch ever and Apple went on to become the most valuable company of all-time."

A real-world demonstration of a thought experiment conducted at the University of Vienna, has produced a result that is somewhat befuddling to people with what the lead researcher calls a "naïve classical world view." Two pairs of particles are either quantum-entangled or not. One person makes the decision as to whether to entangle them or not, and another pair of people measure the particles to see whether they're entangled or not.

In a controversial paper in Nature Physics, theorists claim they can prove that wavefunctions - the entity that determines the probability of different outcomes of measurements on quantum-mechanical particles - are real states.

As a child, I always looked up at the stars and wondered how I could make it into space. Hopefully, I will live to see that day, but for now, a homemade satellite will have to do. The Nanosatisfi team has made it their mission "to provide affordable space exploration for everyone!," and with ArduSat, they move one step closer to reality. ArduSat is a Arduino-controlled miniature 10cm cubic satellite, weighing 1 kg, which is roughly equivalent to half a store bought loaf of bread. Its size might not be impressive, but it packs over 25 sensors including: Myspectral's open source spectrometer, inertial measurement unit, magnetometer, along the standard set, and many others. This impressive little machine boasts a camera to take photographs, it could send messages back to earth, or it can run your space experiments. With the ability to upload code directly to the ArduSat while in space, the possibilities are virtually limitless.

The last time we ran into Ben Heck, the tinkerer extraordinaire was waxing poetic at Maker Faire about the Raspberry Pi and cheese curds. One more thing he also talked about, however, was his latest 3D printer project, which he now explains in greater detail in the latest episode of the Ben Heck Show. Improvements made to the device include use of a Birdstruder for easier access to the filament and the ability to print off an SD card if you don't have a computer handy. The 3D printer also sports an expanded 200-square-millimeter print area with a solid copper cover for added sturdiness and accuracy. As usual, size matters for Mr. Heckendorn so the device got a boost in portability, now neatly folding James Bond-like into a briefcase that measures 18 x 14 x 4.2 inches. Interested in a briefcase printer of your own? Well, Heckendorn mentioned during the Maker Faire interview that he's already working on an improved version and thinking about putting it up on Kickstarter so hope springs eternal. In the meantime, you can glean more details about the device by checking out the video after the break.

Louisville's hackerspace LVL1 is working on a home automation setup for the space, and they call it MOTHER. Using open-source home automation software called HOLOS, the capabilities include: * Monitoring of LVL1 Space Occupancy & Zone Occupancy * Measuring of "Hacktivity Levels" of each Zone * Monitoring of individual member occupancy * INSTANT WOMP MODE! (dubstep everywhere at the press of a button) * Notifications of "Abnormal" hacktivity levels * Monitoring of various websites and notifications of LVL1 mentions * Various "Nagging" (Take out the trash, It's cold please shut the door, I haven't seen you in 3 days, please come visit your mother, etc…) * "Member Scenes" - Auto setting of audio, lights, etc.. based on specific members present * Logging and Graphing of ALL data * Voice recognition and communication * Control of Lighting and appliances * Security System monitoring and notification of alerts * Phone calls and emails based notifications * Google Talk communication with AIML chat integration

During the GNSS Vulnerability 2012 event at the UK's National Physical Laboratory on Wednesday, experts discussed the threat posed by a growing number of GPS jamming and spoofing devices. The increasing popularity of the jammers is troubling, according to conference organizer Bob Cockshott, because even low-power GPS jammers pose a significant threat to cell phone systems, parts of the electrical grid, and the safety of drivers.
