Spot ET's Waste Heat For Chance To Find Alien Life

SlashDot - Sat, 08/23/2014 - 5:21pm
mdsolar passes along this selection from New Scientist describing a (comparatively) low-tech means of scanning the skies for extraterrestrial civilizations: The best-known technique used to search for tech-savvy aliens is eavesdropping on their communications with each other. But this approach assumes ET is chatty in channels we can hear. The new approach, dubbed G-HAT for Glimpsing Heat from Alien Technologies, makes no assumptions about what alien civilisations may be like. "This approach is very different," says Franck Marchis at the SETI Institute in California, who was not involved in the project. "I like it because it doesn't put any constraints on the origin of the civilisation or their willingness to communicate." Instead, it utilises the laws of thermodynamics. All machines and living things give off heat, and that heat is visible as infrared radiation. The G-HAT team combed through the catalogue of images generated by the Wide-field Infrared Survey Explorer, or WISE, which released an infrared map of the entire sky in 2012. A galaxy should emit about 10 per cent of its light in the mid-infrared range, says team leader Jason Wright at Pennsylvania State University. If it gives off much more, it could be being warmed by vast networks of alien technology – though it could also be a sign of more prosaic processes, such as rapid star formation or an actively feeding black hole at the galaxy's centre.

Facebook Experimenting With Blu-ray As a Storage Medium

SlashDot - Sat, 08/23/2014 - 4:10pm
s122604 links to CNN's explanation of what may be the future of cold (or at least lukewarm) storage at Facebook, which is experimenting with massive arrays of Blu-Ray discs for seldom-accessed user files. Says the report: The discs are held in groups of 12 in locked cartridges and are extracted by a robotic arm whenever they're needed. One rack contains 10,000 discs, and is capable of storing a petabyte of data, or one million gigabytes. Blu-ray discs offer a number of advantages versus hard drives. For one thing, the discs are more resilient: they're water- and dust-resistant, and better able to withstand temperature swings. Their data can be restored more quickly, and they're easier to transport. Most important, though, is cost. Because the Blu-ray system doesn't need to be powered when the discs aren't in use, it uses 80% less power than the hard-drive arrangement, cutting overall costs in half.

For Microsoft, $93B Abroad Means Avoiding $30B Tax Hit

SlashDot - Sat, 08/23/2014 - 3:12pm
walterbyrd (182728) writes "Microsoft Corp. is currently sitting on almost $29.6 billion it would owe in U.S. taxes if it repatriated the $92.9 billion of earnings it is keeping offshore, according to disclosures in the company's most recent annual filings with the Securities and Exchange Commission. The amount of money that Microsoft is keeping offshore represents a significant spike from prior years, and the levies the company would owe amount to almost the entire two-year operating budget of the company's home state of Washington."

The Tech Fixes the PS3 Still Needs, Eight Years On

SlashDot - Sat, 08/23/2014 - 2:15pm
An anonymous reader writes "The PlayStation 4 has well and truly arrived, but Sony's still selling its last-gen console by the pallet-load, eight years after first going on sale. Of course, as a new article points out, that's nothing compared to the PS2's astonishing 13 year manufacturing run. To help achieve that, the author outlines some tech fixes the PS3 could still do with, even after all this time, from tighter PS Vita integration, to yes, cross game chat. Can it make it past a decade, too?"

Eruption Of Iceland's Bardarbunga Raises Travel Alert to Red

SlashDot - Sat, 08/23/2014 - 1:18pm
The eruption of the Bardarbunga volcano in central Iceland, which appeared a strong possibility after a series of earthquakes, is currently underway, beneath the ice of the Dyngjujokull glacier. The BBC reports that Iceland has raised its air travel alert to red, its higest level, but that for now all of Iceland's airports remain open. CNN notes that "the underground activity did not immediately result in changes to volcanic activity on the surface ... Because of a pressure from the glacier cap it is uncertain whether the eruption will stay sub-glacial or not, Iceland 2 TV said."

Oregon Sues Oracle For "Abysmal" Healthcare Website

SlashDot - Sat, 08/23/2014 - 12:17pm
SpzToid (869795) writes The state of Oregon sued Oracle America Inc. and six of its top executives Friday, accusing the software giant of fraud for failing to deliver a working website for the Affordable Care Act program. The 126-page lawsuit claims Oracle has committed fraud, lies, and "a pattern of activity that has cost the State and Cover Oregon hundreds of millions of dollars". "Not only were Oracle's claims lies, Oracle's work was abysmal", the lawsuit said. Oregon paid Oracle about $240.3 million for a system that never worked, the suit said. "Today's lawsuit clearly explains how egregiously Oracle has disserved Oregonians and our state agencies", said Oregon Atty. Gen. Ellen Rosenblum in a written statement. "Over the course of our investigation, it became abundantly clear that Oracle repeatedly lied and defrauded the state. Through this legal action, we intend to make our state whole and make sure taxpayers aren't left holding the bag." Oregon's suit alleges that Oracle, the largest tech contractor working on the website, falsely convinced officials to buy "hundreds of millions of dollars of Oracle products and services that failed to perform as promised." It is seeking $200 million in damages. Oracle issued a statement saying the suit "is a desperate attempt to deflect blame from Cover Oregon and the governor for their failures to manage a complex IT project. The complaint is a fictional account of the Oregon Healthcare Project."

It's Dumb To Tell Kids They're Smart

SlashDot - Sat, 08/23/2014 - 11:20am
theodp writes Over at Khan Academy, Salman Khan explains Why I'm Cautious About Telling My Son He's Smart. "Recently," writes Khan, "I put into practice research I had been reading about for the past few years: I decided to praise my son not when he succeeded at things he was already good at, but when he persevered with things that he found difficult. I stressed to him that by struggling, your brain grows. Between the deep body of research on the field of learning mindsets and this personal experience with my son, I am more convinced than ever that mindsets toward learning could matter more than anything else we teach." According to Dr. Carol Dweck, who Khan cites, the secret to raising smart kids is not telling kids that they are. A focus on effort — not on intelligence or ability — says Dweck, is key to success in school and in life.

BBC and FACT Shut Down Doctor Who Fansite

SlashDot - Sat, 08/23/2014 - 10:21am
An anonymous reader writes with this report from Torrentfreak, excerpting: In just a few hours time the brand new season of Doctor Who will premiere, kicking off with the first episode 'Deep Breath'. There's been a huge build up in the media, but for fans who prefer to socialize and obtain news via a dedicated community, today brings bad news. Doctor Who Media (DWM) was a site created in 2010 and during the ensuing four and a half years it amassed around 25,000 dedicated members. A source close to the site told TF that since nothing like it existed officially, DWM's core focus was to provide a central location and community for everything in the 'Whoniverse,' from reconstructions of missing episodes to the latest episodes, and whatever lay between. But yesterday, following a visit by representatives from the BBC and Federation Against Copyright Theft, the site's operator took the decision to shut down the site for good.

Google Announces a New Processor For Project Ara

SlashDot - Sat, 08/23/2014 - 9:24am
rtoz writes Google has just announced a new processor for Project Ara. The mobile Rockchip SoC will function as an applications processor, without requiring a bridge chip. A prototype of the phone with the Rockchip CPU, will be available early next year. Via Google+ post, Project Ara team Head Paul Eremenko says "We view this Rockchip processor as a trailblazer for our vision of a modular architecture where the processor is a node on a network with a single, universal interface -- free from also serving as the network hub for all of the mobile device's peripherals." (Project Ara is Google's effort to create an extensible, modular cellphone; last month we mentioned a custom version of Linux being developed for the project, too.)

2 Galileo Satellites Launched To Wrong Orbit

SlashDot - Sat, 08/23/2014 - 8:30am
As reported by the BBC, two satellites meant to form part of the EU's Galileo global positioning network have been launched into a wrong, lower orbit, and it is unclear whether they can be salvaged. NASASpaceFlight.com has a more detailed account of the launch, which says [D]espite the Arianespace webcast noting no issue with the launch, it was later admitted the satellites were lofted into the wrong orbit. “Following the announcement made by Arianespace on the anomalies of the orbit injection of the Galileo satellites, the teams of industries and agencies involved in the early operations of the satellites are investigating the potential implications on the mission,” noted a short statement, many hours after the event. It is unlikely the satellites can be eased into their correct orbit, even with a large extension to their transit time. However, ESA are not classing the satellites as lost at this time. “Both satellites have been acquired and are safely controlled and operated from ESOC, ESA’s Operations Centre in Darmstadt, Germany,” the Agency added. Over the course of the next "year or so," an additional 24 satellites are slated to complete the Galileo constellation, to be launched by a mixed slate of Ariane and Soyuz rockets.

Securing Networks In the Internet of Things Era

SlashDot - Sat, 08/23/2014 - 4:33am
An anonymous reader writes "Gartner reckons that the number of connected devices will hit 26 billion by 2020, almost 30 times the number of devices connected to the IoT in 2009. This estimate doesn't even include connected PCs, tablets and smartphones. The IoT will represent the biggest change to our relationship with the Internet since its inception. Many IoT devices themselves suffer from security limitations as a result of their minimal computing capabilities. For instance, the majority don't support sufficiently robust mechanisms for authentication, leaving network admins with only weak alternatives or sometimes no alternatives at all. As a result, it can be difficult for organizations to provide secure network access for certain IoT devices."

New EU Rules Will Limit Vacuum Cleaners To 1600W

SlashDot - Sat, 08/23/2014 - 1:42am
AmiMoJo writes "New EU rules are limiting vacuum cleaner motors to 1600W from 2014/09/01. The EU summary of the new rules explains that consumers currently equate watts with cleaning power, which is not the case. Manufacturers will be required to put ratings on packaging, including energy efficiency, cleaning efficiency on hard and carpeted floors, and dust emissions from the exhaust. In the EU vacuum cleaners use more energy than the whole of Denmark, and produce more emissions than dishwashers and washing machines."

Virtual Machine Brings X86 Linux Apps To ARMv7 Devices

SlashDot - Fri, 08/22/2014 - 11:07pm
DeviceGuru writes Eltechs announced a virtual machine that runs 32-bit x86 Linux applications on ARMv7 hardware. The ExaGear VM implements a virtual x86 Linux container on ARMv7 computers and is claimed to be 4.5 times faster than QEMU, according to Eltechs. The VM is based on binary translation technology and requires ARMv7, which means it should run on mini-PCs and SBCs based on Cortex-A8, A7, A9, and A15 processors — but sadly, it won't run on the ARM11 (ARMv6) SoC found on the Raspberry Pi. It also does not support applications that require kernel modules. It currently requires Ubuntu (v12.04 or higher), but will soon support another, unnamed Linux distro, according to Eltechs, which is now accepting half price pre-orders without payment obligation.

Google Wants To Test Driverless Cars In a Simulation

SlashDot - Fri, 08/22/2014 - 6:34pm
An anonymous reader writes Google has been testing its autonomous vehicles on U.S. roads for a while now. In fact, they're required to, by law. "California's regulations stipulate autonomous vehicles must be tested under "controlled conditions" that mimic real-world driving as closely as possible. Usually, that has meant a private test track or temporarily closed public road." It's easy enough to test a few prototypes, but whenever autonomous cars start being produced by manufacturers, it'll become a lot more complicated. Now, Google is lobbying to change that law to allow testing via computer simulation. Safety director Ron Medford said, "Computer simulations are actually more valuable, as they allow manufacturers to test their software under far more conditions and stresses than could possibly be achieved on a test track." Google spokeswoman Katelin Jabbari said, "In a few hours, we can test thousands upon thousands of scenarios which in terms of driving all over again might take decades." Shee adds that simulator data can also easily provide information on how human behavior creeps into driving. "It's not just about the physics of avoiding a crash. It's also about the emotional expectation of passengers and other drivers." For example, when one of Google's computer-controlled cars is cut off, the software brakes harder than it needs to, because this makes the passengers feel safer. Critics say relying heavily on simulation data is flawed because it doesn't take into account how other cars react to the computer's driving.

Illinois University Restricts Access To Social Media, Online Political Content

SlashDot - Fri, 08/22/2014 - 5:53pm
onproton writes Northern Illinois University recently began restricting student access to web pages that contain "illegal or unethical" content which, according to University policy, includes resources used for "political activities...and the organization or participation in meetings, rallies and demonstrations." A student raised concerns after attempting to access the Wikipedia page for Westboro Baptist Church, and receiving a filter message informing him that his access of this page would likely violate the University's Acceptable Use Policy, along with a warning that "all violations would be reviewed." This has lead to questions about whether some policies that restrict student access to information are in the best interest of the primary goal of education.

Ask Slashdot: Where Can I Find Good Replacement Batteries?

SlashDot - Fri, 08/22/2014 - 5:11pm
An anonymous reader writes: I have an old phone with a battery that barely works anymore. My current phone's battery is mediocre — I can put up with it, but I've been thinking about getting a new one. My four-year-old ThinkPad holds less of a charge than I'd like, and less than it did when I bought it. In all these cases, the only thing holding me back from buying a new battery is that I'm not sure where to find a good one. Searching for my phone's battery on Amazon (or any major online retailer) yields a dozen results, all fairly cheap. But which are reliable? They all seem to have varying reviews, ranging from "Perfect official factory replacement!" to "Garbage knock-off, worse than the battery I replaced." Part numbers don't seem to help, as the knock-offs replicate those pretty well. I ask you, Slashdot: where can I find a good replacement battery?

Finding an ISIS Training Camp Using Google Earth

SlashDot - Fri, 08/22/2014 - 4:28pm
An anonymous reader writes: Terrorist organization ISIS has been in the news a lot lately for their hostile activities in Iraq and Syria. They've also been very active online, posting propaganda and photos on various social networking sites to try to recruit more members. Frequently, they'll have pictures of themselves in nondescript locations — but even carefully selected images give clues to a real location. Citizen journalists at Bellingcat analyzed a group of these photos, comparing buildings and bridges in the background to images from Google Earth. With very little to go on, they were able to pinpoint the location of a terrorist training camp.
