alphadogg writes: Reflecting on the popular musician's uneasy relationship with the Internet and social media upon the 57-year-old surprising death. In 2010, Prince "famously shuttered his LotusFlow3r.com website," proclaiming that "The Internet is completely over... All these computers and digital gadgets are no good. They just fill your head with numbers and that can't be good for you." In 2014, The Guardian ran a story titled "Prince quits the Internet," after the singer deleted his social media accounts. He filed a lawsuit against his fans, which was later dropped, for sharing bootlegged copies of his music online. He even banned fans from taking smartphone photos at his concerts in 2013. Prince did seem to open up to the Internet to some degree in the past couple years. Prince's HTNRUN album was posted on Jay Z's Tidal music site last year. In Silicon Valley, Prince is being remembered as a social innovator and a passionate advocate for Black youth," inspiring YesWeCode, Van Jones' initiative to teach 100,000 low-income kids to write code, and hackathons across the country to expose kids in underserved communities to computer science. Bob Brown from Networkworld writes, "News of Prince's death Thursday briefly crashed the TMZ news site. From there, fans flocked to the Internet and social media to mourn this music star who did his darnedest to stay off the grid." RIP Prince.

Morpheus writes: Good morning. I'm talking to you. Yes, you. The one with the squeaking chair and the monitor that needs cleaning. Right now you're wondering why your officemates haven't mentioned the weird story on Slashdot's front page. They haven't mentioned it because they can't see it. Not everyone can accept reality as it is. But you can.

You know. You've always known. The things you see, the things you hear, and smell — they aren't any more real than your dreams. You've drifted through life so far wondering when you're going to wake up. But you don't have to wonder anymore. This is your alarm clock. The only decision you have left to make — the only decision you've ever had to make — is whether you want to wake up, or turn it off and drift back to sleep. In exactly two minutes, your phone is going to ring. If you want to open your eyes, to be born into a world more real than you've ever imagined.. answer it.

Lasrick (2629253) writes The blossoming of online Internet-trading platforms has at least one downside: insufficient inspectors and product controls when it comes to goods relevant to nuclear proliferation. "On Alibaba (and other platforms), one can purchase many of the specialized items needed for the manufacture of nuclear weapons. A short list of items advertised for sale on the site include metals suitable for centrifuge manufacturing, gauges and pumps for centrifuge cascades for uranium enrichment, metallurgical casting equipment suitable for making nuclear weapon 'pits,' and high-speed cameras suitable for use in nuclear weapon diagnostic tests. A company on an Alibaba-owned Chinese Internet-trading platform even posted an ad for the sale of the rare metal gallium, which the seller trumpeted could be used to stabilize plutonium." Although many companies have strict compliance procedures in place to help avoid proliferation, many do not. There are several procedures these platforms can put into place to minimize risk, and both national (and international) regulators have a role to play, as well as shareholders.

An anonymous reader writes: If you've ever heard of the Dunning-Kruger effect, you'll be familiar with David Dunning, professor of psychology at Cornell. He's written an article on the "psychology of human wrongness," explaining how confidence in one's answers tends to be high for people who don't know what they're talking about. He says, "What's curious is that, in many cases, incompetence does not leave people disoriented, perplexed, or cautious. Instead, the incompetent are often blessed with an inappropriate confidence, buoyed by something that feels to them like knowledge."

Dunning goes on: "A whole battery of studies conducted by myself and others have confirmed that people who don't know much about a given set of cognitive, technical, or social skills tend to grossly overestimate their prowess and performance, whether it's grammar, emotional intelligence, logical reasoning, firearm care and safety, debating, or financial knowledge. College students who hand in exams that will earn them Ds and Fs tend to think their efforts will be worthy of far higher grades; low-performing chess players, bridge players, and medical students, and elderly people applying for a renewed driver's license, similarly overestimate their competence by a long shot."

cartechboy (2660665) writes "Sometimes we get carried away with sexy moonshot car tech--whereas most everyday gains are about reducing inefficiencies, piece by piece. Volvo's flywheel energy-recovery prototype is a great example of the latter--not to mention similar to one used in Formula 1 racing. The system recaptures energy that would be wasted in braking, like a hybrid does, to reduce fuel consumption by up to 25 percent. When you hit the brakes, kinetic energy that's usually wasted as heat is transferred to a "Kinetic Energy Recovery System" mounted to the undriven axle. It spools up a carbon flywheel that turns at 60,000 rpm to store the energy. When the driver hits the gas, some of the stored energy is transferred back to power the wheels through a specially designed transmission, either boosting total power to the wheels or substituting for engine torque to cut fuel consumption."

Hugh Pickens writes "The Ukrainian Navy has a small problem on their hands. The Atlantic reports that, after rebooting the Soviet Union's marine mammal program last year with the goal of teaching dolphins to find underwater mines and kill enemy divers, three of the Ukrainian military's new recruits have gone AWOL. Apparently they swam away from their trainers ostensibly in search of a 'mate' out in open waters. It might not be such a big deal except that these dolphins have been trained to 'attack enemy combat swimmers using special knives or pistols fixed to their heads.' Dolphins were trained at Sevastopol for the Soviet Navy as far back as 1973 to find military equipment such as sea mines on the seabed as well as attacking divers and even carrying explosives on their heads to plant on enemy ships. The U.S. has its own dolphin program in San Diego with 40 trained dolphins and sea lions and another 50 in training. U.S. Navy dolphins were deployed in Bahrain in 1987 during a period when Iran was laying down mines in the Persian Gulf to disrupt oil shipments. No word yet on whether 'sharks with frickin' laser beams attached' have been added to the U.S. arsenal." Update: 03/14 14:55 GMT by T : Note that (as the Atlantic has updated their story reached via above link) while there really are militarized dolphins in use around the world, this particular story turns out to be an elaborate prank.
