"In 2012, Richard Branson, Larry Page, and Eric Schmidt announced the launch of Planetary Resources, an ambitious start up with the goal of mining nearby asteroids for natural resources. Now an academic survey of ore-bearing asteroids estimates that only about 10 are likely to have resources worth mining. The new approach is to create a Drake-like equation that starts with the total number of asteroids and determines the percentage that are close enough to Earth, the percentage of these that contain valuable resources, the percentage of these large enough to pay for a space mining mission and so on. Each of these factors is filled with uncertainty but the bottom line is that when it comes to platinum group metals such as platinum, palladium, and iridium there are likely to be very few worth exploiting. That has significant implications for the future of space exploration. With so few commercially-viable space rocks out there, knowing which ones to pursue will be hugely valuable information, concludes the study. And that means the prospecting of asteroids is likely to become a highly secretive commercial endeavor in the not-too-distant future."Read Replies (0)

"Activities, technologies, equipment, or other matters regarding the US Department of Defense are a common topic on Slashdot, both as stories and in discussions. Despite that we seldom see stories regarding the senior leadership of DoD as we do for technologists, the political branches, and lately the NSA. Former Secretary of Defense Robert Gates, who served under both Presidents Bush and Obama, has released a rather biting memoir of his tenure as the Secretary of Defense. The Wall Street Journal has an excerpt: '... despite everyone being "nice" to me, getting anything consequential done was so damnably difficult — even in the midst of two wars. I did not just have to wage war in Afghanistan and Iraq and against al Qaeda; I also had to battle the bureaucratic inertia of the Pentagon, surmount internal conflicts within both administrations, avoid the partisan abyss in Congress, evade the single-minded parochial self-interest of so many members of Congress and resist the magnetic pull exercised by the White House, especially in the Obama administration, to bring everything under its control and micromanagement. Over time, the broad dysfunction of today's Washington wore me down, especially as I tried to maintain a public posture of nonpartisan calm, reason and conciliation. ... difficulties within the executive branch were nothing compared with the pain of dealing with Congress. ... I saw most of Congress as uncivil, incompetent at fulfilling their basic constitutional responsibilities (such as timely appropriations), micromanagerial, parochial, hypocritical, egotistical, thin-skinned, and prone to put self (and re-election) before country.' — More at The Washington Post"Read Replies (0)

"In a keynote talk at this year's Consumer Electronics Show (CES) in Las Vegas, David Pogue (Yahoo's freshly minted technology columnist) suggested that the new 'Yahoo Tech' Website — a key part of the company's latest rebranding — would be targeted at 'normal' people as opposed to 'gearheads.' Based on a map that flashed on the giant screen behind him, which showed the 'normals' clustered in the middle of the country and the 'gearheads' restricted to the coasts, it's clear that Yahoo has embraced a divisive strategy that tries to equate Yahoo's brands with some sort of mythical 'middlebrow' audience that exists within clearly defined borders. (During his presentation, Pogue also flashed a slide that made fun of competing tech-news brands: The Verge was rendered as 'The Urge,' for example, while Gizmodo became 'Gizmoody.') The problem is that rigid audience of 'normals' doesn't exist, at least not in the way that Yahoo envisions. Large numbers of well-educated technology consumers — 'gearheads,' in Pogue's parlance — exist all over the country; to say otherwise is like suggesting that Wyoming is 100 percent Republican, or that everybody who lives in Florida hates snow. In other words, Yahoo's approach to tech content isn't merely schismatic; it's willfully unaware of the variety that exists among technology fans."Read Replies (0)

"Writing in the NY Times, Dr. Haider Javed Warraich shares a dirty little medical secret: doctors do 'Google' their patients, and the practice is likely to only become more common. And while he personally feels the practice should be restricted to situations where there's a genuine safety issue, an anecdote Warraich shares illustrates how patient search could provide insight into what otherwise might be unsolved mysteries — or lead to a snap misdiagnosis: 'I was once taking care of a frail, older patient who came to the hospital feeling very short of breath. It wasn't immediately clear why, but her breathing was getting worse. To look for accidental ingestions, I sent for a drug screen and, to my great surprise, it came back positive for cocaine. It didn't make sense to me, given her age and the person lying before me, and I was concerned she had been the victim of some sort of abuse. She told me she had no idea why there was cocaine in her system. When I walked out of the room, a nurse called me over to her computer. There, on MugShots.com, was a younger version of my patient's face, with details about how she had been detained for cocaine possession more than three decades earlier. I looked away from the screen, feeling like I had violated my patient's privacy. I resumed our medical exam, without bringing up the finding on the Internet, and her subsequent hospital course was uneventful.'"Read Replies (0)

"You can encrypt your password library using a client-side manager or encrypted file container. You could practice your password every day, keep no written record, and do everything else right. You then go in for a serious operation or get in a terrible accident and, when you wake up, suffer severe memory loss. Slashdot readers, what do you consider an acceptable trade-off between proper security and preventing a data-loss catastrophe? I will leave some details and assumptions up to interpretation (budget, whether you have friends or co-workers to rely on, whether your solution will defend against the Government, chance of success, and so forth). For instance, would you split your master password in pieces and pay an attorney to contact you with a piece of it in case of emergency? Would you get a safe deposit box? Some biometric device? Leave the password with your husband, wife, or significant other? What can Slashdot come up with?"Read Replies (0)

"In the beginning, they used catapults, dune buggies, 'jalapeños,' $1 million submarines, and sophisticated drug tunnels to move drugs northward. Now, Mexican drug cartels are taking to high-end industrial drills to carve out literal drug pipelines into the U.S. It's the next big leap in the evolution of the narcos' ingenious smuggle tech. The future of borderland drug running, it turns out, is boring. Jason Kersten reports on the phenomenon in a great GQ feature that focuses on the Sinaloa Cartel, the international crime syndicate believed to be behind the first known narco pipeline in 2008: '...Mexican authorities, responding to reports of a cave-in and flooding near the [All-American] canal, discovered a tunnel unlike anything they'd ever seen. Only ten inches wide, it was essentially a pipe. The Mexican cops traced it back to a house about 600 feet from the border, where they found a tractor-like vehicle with a long barrel on its side—a horizontal directional drill, or HDD.'"Read Replies (0)

"The technology industry has been coasting along on steady, predictable performance gains, as laid out by Moore's law. But stability and predictability are also the ingredients of complacency and inertia. At this stage, Moore's Law may be more analogous to golden handcuffs than to innovation. With its end in sight, systems makers and governments are being challenged to come up with new materials and architectures. The European Commission has written of a need for 'radical innovation in many computing technologies.' The U.S. National Science Foundation, in a recent budget request, said technologies such as carbon nanotube digital circuits will likely be needed, or perhaps molecular-based approaches, including biologically inspired systems. The slowdown in Moore's Law has already hit high-performance computing. Marc Snir, director of the Mathematics and Computer Science Division at the Argonne National Laboratory, outlined in a series of slides the problem of going below 7nm on chips, and the lack of alternative technologies."Read Replies (0)

"The Dallas, Texas police chief has used an unusual weapon in his arsenal to announce firings and other disciplinary measures in the Dallas police force: Twitter. 'Dallas Police Chief David O. Brown has fired or disciplined 27 officers and employees in the last year. And every time he brings down the hammer, he announces it on Facebook and Twitter, specifying exactly who the men and women are and what they did. On Dec. 30, it was five officers and a 911 call operator.' The article goes on to say, 'Chief Brown is, as far as we know, unique among police chiefs in his use of social media. "I'm unaware of anyone else doing this," says Lt. Max Geron, who handles media relations at the Dallas Police Department. "If we weren't the first, we were one of the first." We checked out the Twitter profiles of various departments around the country as well and couldn't find a similar situation. The social media posts aren't an official policy of the DPD, but rather a "push for transparency" initiative, in Lt. Geron's words. "[It comes from] a desire to be more transparent and to get our message out to the greater community," he says.'"Read Replies (0)
