Fully Autonomous Flapping-wing MAV Is As Light As 4 Sheets of A4 Paper 79

Posted by Unknown Lamer
from the paper-airplane-2.0 dept.
Hallie Siegel writes "According to its developers, the DelFly Explorer is the first flapping wing Micro Air Vehicle (MAV) that is able to fly with complete autonomy in unknown environments. Weighing just 20 grams and with a wingspan of 28cm, it is equipped with an onboard stereo vision system. The DelFly Explorer can perform an autonomous take-off, keep its height, and avoid obstacles for as long as its battery lasts (~9 minutes). All sensing and processing is performed on board, so no human or offboard computer is in the loop."

DRM Has Always Been a Horrible Idea 281

Posted by Unknown Lamer
from the except-when-gabe-does-it dept.
An anonymous reader writes "For years, the reaction of the big entertainment companies to digital disruption has been to try and restrict and control, a wrong-headed approach that was bound to backfire. But the entertainment companies were never known for being forward thinking whether it was radio in the 20s or cassette tapes in the 70s or VCRs in the 80s or Napster in the 90s. The reaction was the always the same. Take a defensive position and try to battle the disruptive force. And it never worked. And DRM was perhaps the worst reaction of all, place restrictions on your content that punish the very people who were willing to pay for it, while others were free to use it without restriction. It was an approach that never made much sense, and it's good to know that mounting evidence proves that's the case."

Owncloud 6 Brings Collaborative Open Document Format Editing to the Web 73

Posted by Unknown Lamer
from the process-calculus-for-english-homework dept.
OwnCloud version six was released last week, and part of the release was a pretty major new feature: real-time collaborative editing of ODF documents (the format used by Libreoffice, Calligra, etc.). Although Etherpad has supported collaborating on simple text document for a while now, this is the first Free Software equivalent to Google Docs. From the article: "WebODF is a javascript library that lets you display ODF files in your browser. Think of it as PDF.js, but for ODF. You just throw a webodf.js script on your server, and do a couple of javascript calls to render an ODF file. It works completely client-side, no serverside ODF processing required. ... The collaborative server, included with OwnCloud Documents, lets users join a 'session', which is basically a document with a history of edit operations. Operations are small units of edits (think 'commits'). In a collaborative session, we use Operational Transformation techniques to make sure that operations fired by various clients will eventually result in a consistent state everywhere. When a new client joins an existing session, all earlier operations are played-back for it to reach the current state. Note that this editing is not turn-based; this is true inline collaborative editing where users can join a document and start editing straight away." As always, source is available.

Google Seeks To Throw Out UK Safari Tracking Suit 70

Posted by Unknown Lamer
from the international-relations dept.
judgecorp writes "In the latest twist to the saga of Google's tracking of Safari users, the tech giant has asked to have a U.K. lawsuit dismissed. Google says it is bound by California laws, so plaintiffs will have to come to the U.S. and sue there. Law firm Olswang is bringing the suit on behalf of British users whose Safari browser settings were overridden to help Google target ads; it argues that international organizations should respect the laws that apply where their customers live."

alphadogg writes "Engineers are putting the final touches on a network capable of handling up to 54Tbps of traffic when the Winter Olympics opens on Feb. 7 in the Russian city of Sochi. The two locations where the Olympics will take place — the Olympic village in Sochi and a tight cluster of Alpine venues in the nearby Krasnaya Polyana Mountains — are completely new construction, so this project represents a greenfield environment for Avaya, the company heading up the project. In addition to investing in a telecom infrastructure, Russia is spending billions of dollars to upgrade Sochi's electric power grid, its transportation system and even its sewage treatment facilities."

Polynesians May Have Invented Binary Math 170

Exponential Algorithm In Windows Update Slowing XP Machines 413

Posted by samzenpus
from the no-pep-in-your-step dept.
jones_supa writes "An interesting bug regarding update dependency calculation has been found in Windows XP. By design, machines using Windows Update retrieve patch information from Microsoft's update servers (or possibly WSUS in a company setting). That patch information contains information about each patch: what software it applies to and, critically, what historic patch or patches the current patch supersedes. Unfortunately, the Windows Update client components used an algorithm with exponential scaling when processing these lists. Each additional superseded patch would double the time taken to process the list. With the operating system now very old, those lists have grown long, sometimes to 40 or more items. On a new machine, that processing appeared to be almost instantaneous. It is now very slow. After starting the system, svchost.exe is chewing up the entire processor, sometimes for an hour or more at a time. Wait long enough after booting and the machine will eventually return to normalcy. Microsoft thought that it had this problem fixed in November's Patch Tuesday update after it culled the supersedence lists. That update didn't appear to fix the problem. The company thought that its December update would also provide a solution, with even more aggressive culling. That didn't seem to help either. For one reason or another, Microsoft's test scenarios for the patches didn't reflect the experience of real Windows XP machines."

Judge: NSA Phone Program Likely Unconstitutional 345

Posted by samzenpus
from the stop-listening dept.
schwit1 writes in with the latest on an U.S. District Court ruling over NSA spying. "A federal judge ruled Monday that the National Security Agency's phone surveillance program is likely unconstitutional, Politico reports. U.S. District Court Judge Richard Leon said that the agency's controversial program, first unveiled by former government contractor Edward Snowden earlier this year, appears to violate the Constitution's Fourth Amendment, which states that the 'right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated.' 'I cannot imagine a more "indiscriminate" and "arbitrary invasion" than this systematic and high-tech collection and retention of personal data on virtually every single citizen for purposes of querying it and analyzing it without judicial approval,' Leon wrote in the ruling. The federal ruling came down after activist Larry Klayman filed a lawsuit in June over the program. The suit claimed that the NSA's surveillance 'violates the U.S. Constitution and also federal laws, including, but not limited to, the outrageous breach of privacy, freedom of speech, freedom of association, and the due process rights of American citizens.'"

Army Laser Passes Drone-Killing Test 173

Posted by samzenpus
from the zap-it dept.
Nerval's Lobster writes "Commercial package-delivery drones such as those revealed by Amazon and DHL could face danger from more than shotgun-toting, UAV-hunting yahoos following the successful test of a drone-killing laser by the U.S. Army. Though it's more likely to take aim at enemy observation drones than Amazon's package-deliver 'copters, the U.S. Army's High Energy Laser Mobile Demonstrator (HEL-MD) did prove itself in tests last week by shooting down 90 incoming mortars and a series of Unmanned Aerial Vehicles (UAV). The original goal during the test at White Sands Missile Range in New Mexico was to burn out or blow up mortar rounds and blind the cameras or other sensors carried by drones. The laser proved capable enough to damage or slice off the tails of target drones, which brought them down, according to Terry Bauer, HEL MD program manager, as quoted in the Dec. 11 Army announcement of the test. The quarter-sized beam of super-focused light set off the explosives in the 60-millimeter mortars in mid-flight, leaving the rest to fall 'like a rock,' Bauer said. The laser could target only one mortar at a time, but could switch targets quickly enough to bring down several mortars fired in a single volley. The laser and its power source are contained in a single 500-horsepower, four-axle truck but was directed by a separate Enhanced Multi Mode Radar system. The next step is a move from New Mexico to a testing range in Florida early next year 'to test it in rain and fog and things like that,' according to Bauer."

FDA Seeks Tougher Rules For Antibacterial Soaps 160

Posted by samzenpus
from the getting-clean dept.
barlevg writes "It's long been a concern that the widespread use of antibacterial soaps is contributing towards the evolution of drug-resistant 'superbugs,' but as the Washington Post reports, the Food and Drug Administration also does not believe that there is any evidence to support that the antibacterial agents in soaps are any more effective at killing germs than simply washing with soap and water. Under the terms of a proposal under consideration, the FDA will require that manufacturers making such claims will have to show proof. If they fail to do so, they will be required to change their marketing or even stop selling the products altogether."

Disney Pulls a Reverse Santa, Takes Back Christmas Shows From Amazon Customers 418

Posted by samzenpus
from the naughty-list dept.
Sockatume writes "Since 2011, Amazon Instant Video has sold a series of Christmas shorts from Disney called 'Prep and Landing'. Unfortunately this holiday season, Disney has had a change of heart and has decided to make the shorts exclusive to its own channels. The company went so far as to retroactively withdrawn the shows from Amazon, so that customers who have already paid for them no longer have access. Apparently this reverse-Santa ability is a feature Amazon provides all publishers, and customers have little recourse but to go cap-in-hand to a Disney outlet and pay for the shows again."

Next-Gen Windshield Wipers To Be Based On Jet Fighter "Forcefield" Tech 237

Posted by samzenpus
from the rain-rain-go-away dept.
cartechboy writes "It looks like the old-school windshield wiper is about to be replaced by new technology — but not until 2015. British car-maker McLaren is apparently developing a new window cleaning system that is modeled from fighter jet tech. The company isn't revealing exactly how it will work, but the idea comes from the chief designer simply asking a military source why you don't see wipers on jets as they land. Experts expect McClaren to use constantly active, high-frequency sound waves outside the range of human hearing that will effectively create a force field across a car's windshield to repel water, ice insects and other debris. Similar sound waves are used by dentists to remove plaque from teeth."

From the article: 'Josh Zerlan, the Chief Operating Officer of Butterfly Labs and a person familiar with the Bitcoin network, has said it is highly likely that Nakamoto could be a group of people working the financial sector. Speaking to IBTimes UK on the sidelines of a Global Bitcoin Conference in Bangalore, India, Zerlan said: "One of the prevailing theories, I think has credibility, is that it was some group of people from financial sector that created this. They released it and stepped back and let it go. So, Satoshi Nakamoto is a group of people, I think, is a reasonable possibility."'"

Facebook Tracks the Status Updates and Messages You Don't Write Too 163

Jah-Wren Ryel writes "It turns out Facebook tracks the stuff that people type and then erase before hitting the post button. If you start writing a message, and then think better of it and decide not to post it, Facebook still adds it to the dossier they keep on you. From the article: 'Storing text as you type isn't uncommon on other websites. For example, if you use Gmail, your draft messages are automatically saved as you type them. Even if you close the browser without saving, you can usually find a (nearly) complete copy of the email you were typing in your Drafts folder. Facebook is using essentially the same technology here. The difference is that Google is saving your messages to help you. Facebook users don't expect their unposted thoughts to be collected, nor do they benefit from it.'"

Streaming and Cord-Cutting Take a Toll On the Pay-TV Industry 261

Posted by samzenpus
from the I-want-to-watch-it-now dept.
First time accepted submitter ClarkSchultz writes "Harris Interactive confirms that consumers streaming video content prefer the practice of binge viewing.The news isn't a big shocker to streaming concerns such as Netflix, Amazon, and Redbox Instant which have been mining viewer habits data, but it has an important read-through for broadcasters like CBS, NBC, Fox, and ABC. Though ad rates could fall if more viewers wait until series are available for streaming, the payoffs for quality content are proving lush: 1) CBS says it paid $700K per episode for streaming rights to Under the Dome 2) AMC Networks has pointed to Netflix as contributing to the success of Breaking Bad after initial ratings were soft. If streaming wins, who loses? Front and center is the Pay-TV industry. A wave of merger rumors (Charter/Cox/Time Warner Cable/Comcast/Dish Network) indicates the industry knows the trend of subscriber losses to the cord-cutting phenomenon will continue. An online TV initiative from a tech heavyweight like Sony, Apple, Google, or Intel could also disrupt the industry enough to put cable and satellite companies into an even bigger tailspin."

CBS 60 Minutes: NSA Speaks Out On Snowden, Spying 504

Posted by samzenpus
from the what-did-he-get? dept.
An anonymous reader writes "This week CBS New's 60 Minutes program had a broadcast segment devoted to the NSA, and additional online features. It revealed that the first secret Snowden stole was the test and answers for a technical examination to get a job at NSA. When working at home, Snowden covered his head and screen with a hood so that his girlfriend couldn't see what he was doing. NSA considered the possibility that Snowden left malicious software behind and removed every computer and cable that Snowden had access to from its classified network, costing tens of millions of dollars. Snowden took approximately 1.7 million classified documents. Snowden never approached any of multiple Inspectors General, supervisors, or Congressional oversight committee members about his concerns. Snowden's activity caught the notice of other System Administrators. There were also other interesting details, such as the NSA has a highly competitive intern program for High School students that are given a Top Secret clearance and a chance to break codes that have resisted the efforts of NSA's analysts — some succeed. The NSA is only targeting the communications, as opposed to metadata, of less than 60 Americans. Targeting the actual communications of Americans, rather than metadata, requires a probable cause finding and a specific court order. NSA analysts working with metadata don't have access to the name, and can't listen to the call. The NSA's work is driven by requests for information by other parts of the government, and there are about 31,000 requests. Snowden apparently managed to steal a copy of that document, the 'crown jewels' of the intelligence world. With that information, foreign nations would know what the US does and doesn't know, and how to exploit it."

The Business of Attention Deficit Disorder 246

Posted by timothy
from the drug-'em-all-let-god-sort-'em-out dept.
Hugh Pickens DOT Com writes "Alan Schwarz writes in the NYT that the rise of ADHD diagnoses and prescriptions for stimulants over the years have coincided with a remarkably successful two-decade campaign by pharmaceutical companies to publicize the syndrome and promote the pills to doctors, educators and parents. 'The numbers make it look like an epidemic. Well, it's not. It's preposterous,' says Dr. Keith Conners, a psychologist who has led the fight to legitimize attention deficit hyperactivity disorder for more than fifty years. Few dispute that classic ADHD, historically estimated to affect 5 percent of children, is a legitimate disability that impedes success at school, work and personal life. But recent data from the CDC show that the diagnosis had been made in 15 percent of high school-age children, and that the number of children on medication for the disorder had soared to 3.5 million from 600,000 in 1990."

That application was approved by the then Ministry of Economic Development, a decision appealed by the Horowhenua Library Trust and software firm Catalyst IT. A judgment delivered by assistant commissioner of trademarks Jennie Walden found the two pieces of software were largely the same and that it was likely a 'substantial number' of people would be confused or deceived if Liblime used the Koha trademark."
