US Successfully Tests Self-Steering Bullets

Slashdot - 52 min 4 sec ago
mpicpp sends this report from The Independent: The United States Department of Defense has carried out what it says is its most successful test yet of a bullet that can steer itself towards moving targets. Experienced testers have used the technology to hit targets that were actively evading the shot, and even novices that were using the system for the first time were able to hit moving targets. The project, which is known as Extreme Accuracy Tasked Ordnance weapon, or Exacto, is being made for the American government's military research agency, DARPA. It is thought to use small fins that shoot out of the bullet and re-direct its path, but the U.S. has not disclosed how it works. Technology in the bullet allows it to compensate for weather and wind, as well as the movement of people it is being fired at, and curve itself in the air as it heads towards its target.

University Overrules Professor Who Failed Entire Management Class

Slashdot - 1 hour 34 min ago
McGruber writes: After a semester of disrespect, backstabbing, lying, and cheating, Texas A&M Galveston Professor Irwin Horwitz had all he could take. He "sent a lengthy email to his Strategic Management class explaining that they would all be failing the course. He said the students proved to be incompetent and lack the maturity level to enter the workforce." Professor Horwitz's email cited examples of students cheating, telling him to "chill out," and inappropriate conduct. He said students spread untrue rumors about him online, and he said at one point he even felt the need to have police protection in class. "I was dealing with cheating, dealing with individuals swearing at me both in and out of class, it got to the point that the school had to put security guards at that class and another class," said Horowitz. However, Vice President of Academic Affairs Dr. Patrick Louchouarn made it very clear that the failing grades won't stick. The department head will take over the class until the end of the semester, according to school officials.

Signs of Subsurface 'Alien' Life Found In Antarctica

Slashdot - 2 hours 15 min ago
astroengine writes: An airborne survey of a presumably dry Antarctic valley revealed a stunning and unexpected interconnected subsurface briny aquifer deep beneath the frozen tundra, a finding that not only has implications for understanding extreme habitats for life on Earth, but the potential for life elsewhere in the solar system, particularly Mars. The briny liquid — about twice as salty as seawater — was discovered about 200 miles underground in a region known as Taylor Valley. The aquifer is widespread, extending from the Ross Sea's McMurdo Sound more than 11 miles into the eastern part of valley. A second system was found connecting Taylor Glacier with the ice-cover Lake Bonney. But the survey, which covered 114 square miles, may have just uncovered the proverbial tip of the iceberg.

China's Tencent Launches Smart Hardware OS To Rival Alibaba

Slashdot - 3 hours 1 min ago
An anonymous reader writes: Chinese internet and media giant Tencent Holdings has today launched an operating system for mobile devices such as internet-connected phones, TVs, smartwatches and other IoT products. Tencent Operating System (OS) TOS+ is open to all developers and manufacturers free of charge should they agree to share their revenue – a framework similar to Google's popular Android mobile OS. The new Tencent OS offering, which provides voice recognition and mobile payment systems, will rival other home-grown operating systems looking to conquer the smart hardware arena with connected wearables, TVs and smart homeware technology. These competitors include smartphone maker Xiaomi and Asia's largest internet company Alibaba, who hopes to see its recently launched Yun OS eventually installed on tens of millions of smartphones. The Chinese systems for mobile and hardware products provide an alternative to Google's services, which constantly face challenges across the country due to strict censorship and licensing laws.

TeslaCrypt Isn't All That Cryptic

Slashdot - 3 hours 43 min ago
citpyrc writes: TeslaCrypt, the latest-and-greatest ransomware branch off of the CryptoWall family, claims to the unwitting user that his/her documents are encrypted with "a unique public key generated for this computer". This coudn't be farther from truth. In actuality, the developers of this malware appear to have been lazy and implemented encryption using symmetric AES256 with a decryption key generated on the user's machine. If any of your machines are afflicted, Talos has developed a tool that can be used to generate the user's machine's symmetric key and decrypt all of the ransomed files.

Feds Say It's Time To Cut Back On Fluoride In Drinking Water

Slashdot - 4 hours 41 min ago
An anonymous reader writes: Federal health officials Monday changed the recommended amount of fluoride in drinking water for the first time since 1962, cutting by almost half the maximum amount of fluoride that should be added to drinking supplies. The Department of Health and Human Services recommended 0.7 milligrams of fluoride per liter of water instead of the long-standing range of 0.7 to 1.2 milligrams. The change is recommended because now Americans have access to more sources of fluoride, such as toothpaste and mouth rinses, than they did when fluoridation was first introduced in the United States,' Dr. Boris Lushniak, the deputy surgeon general, told reporters during a conference call.

ATT, DirecTV Mega-Merger May Go Through

Slashdot - 5 hours 21 min ago
An anonymous reader writes: Hot on the heels of Comcast's failed attempt to swallow up Time Warner Cable, AT&T's pursuit of satellite provider DirecTV is plowing forward. What would be the result of a wireline and cellular mega-monopoly buying one of only two subscription satellite TV providers? Has to be worse than a Comcast/TWC marriage ... at least there, the territories and services offered didn't overlap at all, but AT&T offers voice, data, and television in many markets already. Adding satellite would stifle competition for television services (and to a lesser extent, because satellite is only best suited for rural installations, data).

How To Increase the Number of Female Engineers

Slashdot - 6 hours 2 min ago
HughPickens.com writes: Lina Nilsson writes in an op-ed piece in the NY Times that she looks with despair at estimates that only about 14 percent of engineers in the work force are women. But there may be a solution to the disparity that is much simpler than targeted recruitment efforts. "An experience here at the University of California, Berkeley, where I teach, suggests that if the content of the work itself is made more societally meaningful, women will enroll in droves," writes Nilsson. "That applies not only to computer engineering but also to more traditional, equally male-dominated fields like mechanical and chemical engineering." Nilsson says that Blum Center for Developing Economies recently began a new program that, without any targeted outreach, achieved 50 percent female enrollment in just one academic year. In the fall of 2014, UC Berkeley began offering a new Ph.D. minor in development engineering for students doing thesis work on solutions for low-income communities. They are designing affordable solutions for clean drinking water, inventing medical diagnostic equipment for neglected tropical diseases and enabling local manufacturing in poor and remote regions. According to Nilsson, women seem to be drawn to engineering projects that attempt to achieve societal good. She notes that MIT, the University of Minnesota, Penn State, Santa Clara University, Arizona State, and the University of Michigan have programs aimed at reducing global poverty and inequality that have achieved similar results. For example, at Princeton, the student chapter of Engineers Without Borders has an executive board that is nearly 70 percent female, reflecting the overall club composition. "It shows that the key to increasing the number of female engineers may not just be mentorship programs or child care centers, although those are important," concludes Nilsson. "It may be about reframing the goals of engineering research and curriculums to be more relevant to societal needs. It is not just about gender equity — it is about doing better engineering for us all."

A Cheap, Ubiquitous Earthquake Warning System

Slashdot - 9 hours 3 min ago
Tekla Perry writes: Earthquake alert systems that give a 10 or 20 second warning of an impending temblor, enabling automatic systems to shut down and people to take cover, are hugely expensive to build and operate. (One estimate is $38.3 milllion for equipment to span California, and another $16.1 million annually to operate.) But a Palo Alto entrepreneur thinks he's got a way to sense earthquakes and provide alerts far more cheaply and with much greater resolution. And he's got money from the National Science Foundation to begin the first test of his system — covering the Bay Area from Santa Cruz to Napa and the cities of Hollister, Coalinga, and Parkfield. He starts that test next month.

Kerbal Space Program 1.0 Released After 4 Years of Development

Slashdot - 10 hours 30 min ago
hampton2600 writes: The beloved space simulator game Kerbal Space Program has just hit version 1.0 after four years in development. It has risen to prominence in public beta, but the full release brings a host of new features: "The flight model has had a complete overhaul, meaning the lift is now calculated correctly to all lift-generating parts, which includes lifting bodies. The drag simulation has also been completely revised, and uses automatically pre-calculated data based on the each part’s geometry, to be finally applied based on not just the orientation of parts in flight, but also taking other parts into consideration. ... A new heating simulation has been implemented together with the improved aerodynamics. Now, not only temperature but also energy flux is considered when making heat calculations, meaning radiative, conductive, and convective heating and cooling are all simulated and all parts have their individual thermal properties. Parts will emit a blackbody radiation glow if they get hot enough." To the mun!

Why Our Antiquated Power Grid Needs Battery Storage

Slashdot - 12 hours 4 sec ago
Lucas123 writes: Last year, renewable energy sources accounted for half of new installed electric-generation capacity (natural gas units made up most of the remainder). As more photovoltaic panels are installed on rooftops around the nation, an antiquated power grid is being overburdened by a bidirectional load its was never engineered to handle. The Hawaiian Electric Company, for example, said it's struggling with electricity "backflow" that could destabilize its system. Batteries for distributed renewable power has the potential to mitigate the load on the national grid by allowing a redistribution of power during peak hours. Because of this, Tesla, which is expected to announce batteries for homes and utilities on Thursday, and others are targeting a market estimated to be worth $1.2B by 2019. Along with taking up some of the load during peak load, battery capacity can be used when power isn't being generated by renewable systems, such as at night and during inclement weather. That also reduces grid demand.

New Zero Day Disclosed In WordPress Core Engine

Slashdot - 12 hours 58 min ago
Trailrunner7 writes: WordPress security issues have for the most part involved a vulnerable plug-in, but a Finnish researcher has disclosed some details on a zero-day vulnerability he discovered in the WordPress 4.2 and earlier core engine that could lead to remote code execution on the webserver. Juoko Pynnonen of Klikki Oy reported a new and unpatched stored cross-site scripting vulnerability in the platform; a similar bug was patched this week by WordPress developers, but only 14 months after it was reported. The vulnerability allows an attacker to inject JavaScript in the WordPress comment field; the comment has to be at least 66,000 characters long and it will be triggered when the comment is viewed, Pynnonen said. "An unauthenticated attacker can store JavaScript on WordPress pages and blog posts. If triggered by an administrator, this leads to server-side code execution under default settings," Pynnonen said. "A usable comment form is required. It looks like the script is not executed in the admin Dashboard, but only when viewing the post/page where the comment was entered. If comment moderation is enabled (the default setting) then the comment won't appear on the page until it has been approved by an admin/moderator. Under default settings, after one 'harmless' comment is approved, the attacker is free from subsequent moderation and can inject the exploit to several pages and blog posts."

Valve Pulls the Plug On Paid Mods For Skyrim

Slashdot - 13 hours 57 min ago
westlake writes: Valve has abandoned its attempt to introduce paid mods to Skyrim on Steamworks, following furious and unrelenting complaints by the gaming community that did not spare Gabe Newell. Valve said, "[O]ur main goals were to allow mod makers the opportunity to work on their mods full time if they wanted to, and to encourage developers to provide better support to their mod communities. We thought this would result in better mods for everyone, both free & paid." Bethesda had similar goals, saying, "There are certainly other ways of supporting modders, through donations and other options. We are in favor of all of them. One doesn't replace another, and we want the choice to be the community’s. Yet, in just one day, a popular mod developer made more on the Skyrim paid workshop than he made in all the years he asked for donations."

New Privacy Threat: Automated Vehicle Occupancy Detection

Slashdot - 15 hours 56 min ago
An anonymous reader writes: The Electronic Frontier Foundation is warning against a new potential privacy threat: cameras that look inside cars and try to identify how many people are inside. This technology is a natural combination of simpler ones that have existed for years: basic object recognition software and road-side cameras (red light cameras, speeding cameras, license plate readers — you name it). Of course, we can extrapolate just a bit further, and point out that as soon as the cameras have high enough resolution, they can start running face recognition algorithms on the images, and determine the identities of a vehicle's occupants. "The San Diego Association of Governments (SANDAG), a government umbrella group that develops transportation and public safety initiatives across the San Diego County region, estimates that 15% of drivers in High Occupancy Vehicle (HOV) lanes aren't supposed to be there. After coming up short with earlier experimental projects, the agency is now testing a brand new technology to crack down on carpool-lane scofflaws on the I-15 freeway. ... In short: the technology is looking at your image, the image of the people you're with, your location, and your license plate. (SANDAG told CBS the systems will not be storing license plate data during the trial phase and the system will, at least for now, automatically redact images of drivers and passengers. Xerox's software, however, allows police the option of using a weaker form of redaction that can be reversed on request.)"

The Engineer's Lament -- Prioritizing Car Safety Issues

Slashdot - 17 hours 54 min ago
An anonymous reader writes: Malcolm Gladwell has an article in The New Yorker about how automotive engineers handle issues of safety. There have been tons of car-related recalls lately, and even before that, we'd often hear about how some piece of engineering on a car was leading to a bunch of deaths. Sometimes it was a mistake, and sometimes it was an intentional design. But we hear about these issues through the lens of sensationalized media and public outrage — the engineers working on these problems understand better that it's how you drive that gets you into trouble far more than what you drive. For example, the Ford Pinto became infamous for catching fire in crashes back in the 1970s. Gladwell says, "That's a rare event—it happens once in every hundred crashes. In 1975-76, 1.9 per cent of all cars on the road were Pintos, and Pintos were involved in 1.9 per cent of all fatal fires. Let's try again. About fifteen per cent of fatal fires resulted from rear collisions. If we look just at that subset of the subset, Schwartz shows, we finally see a pattern. Pintos were involved in 4.1 per cent of all rear-collision fire fatalities—which is to say that they may have been as safe as or safer than other cars in most respects but less safe in this one. ... You and I would feel safer in a car that met the 301 standard. But the engineer, whose aim is to maximize safety within a series of material constraints, cannot be distracted by how you and I feel."

Holographic Principle Could Apply To Our Universe

Slashdot - 18 hours 35 min ago
New submitter citpyrc sends this news from the Vienna University of Technology: The "holographic principle" asserts that a mathematical description of the universe actually requires one fewer dimension than it seems. What we perceive as three dimensional may just be the image of two dimensional processes on a huge cosmic horizon. Up until now, this principle has only been studied in exotic spaces with negative curvature. This is interesting from a theoretical point of view, but such spaces are quite different from the space in our own universe. Results obtained by scientists at Vienna (abstract) now suggest that the holographic principle even holds in a flat spacetime, like ours.

Texas Admonishes Judge For Posting Facebook Updates About Her Trials

Slashdot - Mon, 04/27/2015 - 23:30
An anonymous reader writes: Michelle Slaughter, a Galveston County judge, says she will appeal a public admonition from state officials that criticized her Facebook posts about cases brought before her court. From the article: "The State Commission on Judicial Conduct ordered Michelle Slaughter, a Galveston County judge, to enroll in a four-hour class on the 'proper and ethical use of social media by judges.' The panel concluded that the judge's posts cast 'reasonable doubt' on her impartiality. At the beginning of a high-profile trial last year in which a father was accused of keeping his nine-year-old son in a six-foot by eight-foot wooden box, the judge instructed jurors not to discuss the case against defendant David Wieseckel with anyone. 'Again, this is by any means of communication. So no texting, e-mailing, talking person to person or on the phone or on Facebook. Any of that is absolutely forbidden,' the judge told jurors. But Slaughter didn't take her own advice, leading to her removal from the case and a mistrial. The defendant eventual was acquitted of unlawful-restraint-of-a-child charges."
