How MIT and Caltech's Coding Breakthrough Could Accelerate Mobile Network Speeds

Cellphones 129

colinneagle (2544914) writes "What if you could transmit data without link layer flow control bogging down throughput with retransmission requests, and also optimize the size of the transmission for network efficiency and application latency constraints? In a Network World post, blogger Steve Patterson breaks down a recent breakthrough in stateless transmission using Random Linear Network Coding, or RLNC, which led to a joint venture between researchers at MIT, Caltech, and the University of Aalborg in Denmark called Code On Technologies.

The RLNC-encoded transmission improved video quality because packet loss in the RLNC case did not require the retransmission of lost packets. The RLNC-encoded video was downloaded five times faster than the native video stream time, and the RLNC-encoded video streamed fast enough to be rendered without interruption.

In over-simplified terms, each RLNC encoded packet sent is encoded using the immediately earlier sequenced packet and randomly generated coefficients, using a linear algebra function. The combined packet length is no longer than either of the two packets from which it is composed. When a packet is lost, the missing packet can be mathematically derived from a later-sequenced packet that includes earlier-sequenced packets and the coefficients used to encode the packet."

mpicpp (3454017) writes "YouTube has released a tool that can show you how your video-streaming quality compares to your neighbor's. 'The Google Video Quality Report is available to people in the U.S. and Canada, where it launched in January. It compares your streaming video quality to three standards: HD Verified, when your provider can deliver HD video consistently at a resolution of at least 720p without buffering or interruptions; Standard Definition, for consistent video streaming at 360p; and Lower Definition, for videos that regularly play at less than 360p or often are interrupted."

LoLobey (1932986) writes "Scott Adams has proposed a pyramid project to save the world via energy generation and tourism. Basically build giant pyramids, miles wide and high, in the desert to generate power via chimney effect and photo voltaics with added features for tourism (he's planning ahead for when robots take over all the work and we'll need something to do). He's had a few "Big Ideas" lately (canals, ice bergs, ion energy)."

Former Microsoft CEO Steve Ballmer Buys the LA Clippers For $2 Billion

The Almighty Buck 270

DroidJason1 (3589319) writes "Former Microsoft CEO Steve Ballmer has purchased the LA Clippers for a whopping $2 billion, also setting a new record price for an NBA team. This deal is apparently tentative until Donald Sterling gives his blessing. Twenty-nine other NBA owners need to offer their approval as well, but that shouldn't be a problem as long as Ballmer reaffirms his commitment of keeping the Clippers in Los Angeles. Interestingly, Donald Sterling had purchased the team back in June of 1981 for $12.5 million." We talked about this earlier in the week when rumors of the purchase started circulating.

An anonymous reader writes "LeVar Burton and the rest of the Reading Rainbow crew opened a Kickstarter campaign to bring back Reading Rainbow yesterday, with the ambitious goal of collecting a million dollars for their cause. They are now at almost two million dollars, with over a month left to go. 'This Kickstarter campaign is about reaching every web-connected child. Universal access. Thousands of more books than what we have now. And hundreds of more video field trips,' Burton said."

Bismillah (993337) writes "An interesting study by WilmerHale lawyers and Intel's assistant general counsel Ann Armstrong looked into how much royalty payments and demands actually amount to per device, and found the cost so high it threatens industry profitability and competitiveness. 'As the bank robber Willie Sutton is reported to have said, he robbed banks 'because that's where the money is' - so too of smartphones for patent holders,' the authors wrote."

In First American TV Interview, Snowden Talks Accountability and Patriotism

Government 389

mspohr (589790) points out NBC News's interview with Edward Snowden, the first time Snowden has talked with an American television reporter. It's a wide-ranging conversation, in which Snowden emphasizes his ongoing belief that he did the right thing to release the many documents that he did, even at the cost of his ability to travel. Snowden told NBC's Brian Williams "he had tried to go through channels before leaking documents to journalists, repeatedly raising objections inside the NSA, in writing, to its widespread use of surveillance. But he said he was told, "more or less, in bureaucratic language, 'You should stop asking questions.'" Two U.S. officials confirmed Wednesday that Snowden sent at least one email to the NSA's office of general counsel raising policy and legal questions." Perhaps paving the way to eventual repatriation, Snowden also indicated that he would be willing to accept a "short period" behind bars. But, he said, the U.S. should "reform the Espionage Act to distinguish between people who sell secrets to foreign governments for their own gain and people who return information to public hands for the purpose of serving the public interest," and to include contractors as well as government employees.

Imparting Malware Resistance With a Randomizing Compiler

First time accepted submitter wheelbarrio (1784594) writes with this news from the Economist: "Inspired by the natural resistance offered to pathogens by genetically diverse host populations, Dr Michael Franz at UCI suggests that common software be similarly hardened against attack by generating a unique executable for each install. It sounds like a cute idea, although the article doesn't provide examples of what kinds of diversity are possible whilst maintaining the program logic, nor what kind of attacks would be prevented with this approach." This might reduce the value of MD5 sums, though.

Curved TVs Nothing But a Gimmick

Television 261

Lucas123 (935744) writes "Currently, the hottest trend from TV manufacturers is to offer curved panels, but analysts say it's nothing more than a ploy to pander to consumers who want the latest, coolest-looking tech in their home. In the end, the TVs don't offer better picture quality. In fact, they offer a degraded view to anyone sitting off center. Samsung and LG claim that the curve provides a cinema-like experience by offering a more balanced and uniform view so that the edges of the set don't appear further away than the middle. Paul Gray, director of European TV Research for DisplaySearch, said those claims are nothing by pseudo-science. "Curved screens are a gimmick, much along the same lines as 3D TVs are," said Paul O'Donovan, Gartner's principal analyst for consumer electronics research."

Not A Hoverboard, but Close (Video)

Transportation 66

It's a one-wheeled, self-balancing electric skateboard called (appropriately) the Onewheel. You can't buy one right now. They've already shipped all of their first production runs and still have Kickstarter backers' orders to fulfill. After that, though, they might make one for you -- if you come up with a deposit of $500 against a total price of $1499. Plus shipping. This may seem like a lot of money to some people, but enough folks have found it reasonable that Onewheel has sold out not just its first production run but also the second one. Their Kickstarter success was nothing short of amazing, with $630,862 raised although their goal was only $100,000. Inventor Kyle Doerksen is the man behind Onewheel, but he's also one of the people behind Faraday Bicycles, whose flagship model costs $3500 -- and whose initial production run is also sold out -- which means there are people around who are willing to pay $3500 for an electric bicycle instead of putting a motor kit on a used Schwinn for a total cost of less than $500 (with a little careful shopping).

The Energy Saved By Ditching DVDs Could Power 200,000 Homes

Media 339

Daniel_Stuckey (2647775) writes "The environmental benefits of streaming a movie (or downloading it) rather than purchasing a DVD are staggering, according to a new U.S. government study by researchers at the Lawrence Berkeley National Laboratory. If all DVDs purchased in 2011 were streamed instead, the energy savings would have been enough to meet the electricity demands of roughly 200,000 households. It would have cut roughly 2 billion kilograms of carbon emissions. According to the study, published in Environmental Research Letters, even when you take into account cloud storage, data servers, the streaming device, streaming uses much less energy than purchasing a DVD. If, like me, you're thinking, 'who buys DVDs anymore, anyways?', the answer is 'a lot of people.'" The linked paper is all there, too — not just an abstract and a paywall.

He argues that NYC could save millions of dollars with the Free and Open Source Software Preferences Act 2014, pointing out that the city currently has a $67 million Microsoft ELA. Kallos said: 'It is time for government to modernize and start appreciating the same cost savings as everyone else.'"

'Our best bet for space exploration could be printing humans, organically, on another planet,' said Steltzner."

Iranian Hacker Group Created Fake News Organization For Social Engineering

itwbennett (1594911) writes "A suspected Iranian hacker group seeded Facebook and LinkedIn with bogus profiles of attractive women and even created a fake online news organization to get digitally closer to more than 2,000 U.S. military members, defense contractors and lobbyists it wanted to spy on, according to a report by security consultancy iSight Partners. The group is suspected to be in Iran, based on their working patterns and the location of their command-and-control infrastructure, said Patrick McBride, vice president of iSight's marketing and communications. Their activity is consistent with government-sponsored espionage campaigns, but 'we don't have anything specific tying them back to the government,' he added." Adds reader wiredmikey (1824622): "The recently uncovered activity, which iSIGHT Partners calls NEWSCASTER, was a 'brazen, complex multi-year cyber-espionage that used a low-tech approach to avoid traditional security defenses–exploiting social media and people who are often the 'weakest link' in the security chain.' ... Working undetected since 2011, targets included senior U.S. military and diplomatic personnel, congressional personnel, Washington D.C. area journalists, U.S. think tanks, and defense contractors in the U.S. and Israel."

SpaceX To Present Manned Dragon Capsule

camperdave (969942) writes "SpaceX CEO Elon Musk is set to unveil the Dragon V2 at a media event from Hawthorne, California, tonight at 7 pm. Pacific. The 'Dragon V2' is an upgraded, man rated version of the unmanned spaceship that has made several successful cargo trips to the International Space Station. The new craft will carry a mix of cargo and up to a seven crewmembers to the ISS. According to Musk, this is 'Actual flight design hardware of crew Dragon, not a mockup.' Following the space shuttle's forced retirement in 2011, US astronauts have been totally dependent on the Russian Soyuz capsules for ferry rides to orbit and back. The crisis in Ukraine, which has resulted in some U.S. economic sanctions imposed against Russia, also has the potential to threaten U.S. access to the ISS as the Russian government considers reciprocal sanctions of its own. 'Sounds like this might be a good time to unveil the new Dragon Mk 2 spaceship that @SpaceX has been working on with @NASA,' Musk tweeted. SpaceX is one of three commercial space companies competing for funding from NASA's Commercial Crew Transportation Capability program." (You can watch the event as a webcast.)

OpenSSL To Undergo Security Audit, Gets Cash For 2 Developers

Trailrunner7 (1100399) writes "Scarcely a month after announcing the formation of a group designed to help fund open source projects, the Core Infrastructure Initiative has decided to provide the OpenSSL Project with enough money to hire two full-time developers and also will fund an audit of OpenSSL by the Open Crypto Audit Project. The CII is backed by a who's who of tech companies, including Google, Microsoft, IBM, the Linux Foundation, Facebook and Amazon, and the group added a number of new members this week, as well. Adobe, Bloomberg, HP Huawei and Salesforce.com have joined the CII and will provide financial backing. Now, the OCAP team, which includes Johns Hopkins professor and cryptographer Matthew Green, will have the money to fund an audit of OpenSSL, as well. OpenSSL took a major hit earlier this year with the revelation of the Heartbleed vulnerability, which sent the Internet into a panic, as the software runs on more than 60 percent of SSL-protected sites."

Next IE Version Will Feature Web Audio, Media Capture, ES6 Promises, and HTTP/2

Internet Explorer 173

An anonymous reader writes "Microsoft [Wednesday] announced it is developing at least four new features for the next release of Internet Explorer (IE): Web Audio API, Media Capture and Streams, ES6 Promises, and HTTP/2. The company says this is not an exhaustive list of what to expect in the next version, but merely what it is currently confident that it will be able to deliver. For those who don't know, HTTP/2 is a faster protocol for transporting Web content. It is based on Google's SPDY open networking protocol and is currently being standardized by the IETF. Web Audio is a JavaScript API for processing and synthesizing audio in Web applications while Media Capture provides access to the user's local audio and video input/output devices. Promises is meant to help developers write cleaner asynchronous code."

Mutant Registration vs. Vaccine Registration

Medicine 493

Responding to an editorial endorsing a national vaccine registry in Canada (though the same kind of registry could be and has been proposed in the U.S. with the same logic), an anonymous reader writes "Vaccine Registration makes me think of Mutant and Superhero registration. The reasons are similar. It's based on fear and misinformation. People fear that unvaccinated people will doom us all. Sound familiar? The difference is this is real. (Oh, and they probably won't use sentinels to track down the dangerous unvaccinated folks.) Thoughts?" From the linked editorial: "A national vaccination registry would identify which Canadians have been fully vaccinated, those who have received less than a full dose of shots, and those who have not been vaccinated at all. Having a vaccine registry in place in the event of an outbreak of measles, whooping cough, and diseases like these would enable public health officials to identify the children and adults who need vaccinations. Getting them the shots they need would reduce the risk of anyone on the list getting sick, and would also reduce the threat of an outbreak in the community in which they live or travel to [and] from." In the U.S., immunization records — at least, ones which have been put in electronic form at all — are maintained in a mix of databases, including at the state level, or maintained by cities, or by insurance companies and medical providers. Here, some people (like the reader who submitted this story) also see a potential for unwarranted privacy invasion in a national vaccination registry; however, their case isn't helped by often being tied to opposition to vaccination more generally.

concertina226 (2447056) writes "Scientists from the University of Eastern Finland have found that people who have high levels of cynical distrust are three times as likely to suffer from dementia in later life, than those who have more faith in other people. Their study is the first of its kind to look at the relationship between cynicism and dementia. Entitled: 'Late-life cynical distrust, risk of incident dementia, and mortality in a population-based cohort', it is published in the latest issue of the journal Neurology. Over a period of eight years, the researchers studied 1,499 people, who all had an average age of 71. The participants were given tests for dementia and a questionnaire to measure their level of cynicism, based on the Cook-Medley Scale."

Wikia and Sony Playing Licensing Mind Tricks

Sony 108

TuringTest (533084) writes "Popular culture website Wikia originally hosted its user-contributed content under a free, sharealike Commercial Commons license (CC-BY-SA). At least as soon as 2003, some specific wikis decided to use the non-commercial CC-BY-NC license instead: hey, this license supposedly protects the authors, and anyone is free to choose how they want to license their work anyway, right? However, in late 2012 Wikia added to its License terms of service a retroactive clause for all its non-commercial content, granting Wikia an exclusive right to use this content in commercial contexts, effectively making all CC-BY-NC content dual-licensed. And today, Wikia is publicizing a partnership with Sony to display Wikia content on Smart TVs, a clear commercial use. A similar event happened at TV Tropes when the site owners single-handedly changed the site's copyright notice from ShareAlike to the incompatible NonCommercial, without notifying nor requesting consent from its contributors. Is this the ultimate fate of all wikis? Do Creative Commons licenses hold any weight for community websites?"

Valve's Steam Machines Delayed, Won't Be Coming In 2014

Valve's Eric Hope explains on Steam Forums why the work on controller is causing the delay: 'We're now using wireless prototype controllers to conduct live playtests, with everyone from industry professionals to die-hard gamers to casual gamers. It's generating a ton of useful feedback, and it means we'll be able to make the controller a lot better. Of course, it's also keeping us pretty busy making all those improvements. Realistically, we're now looking at a release window of 2015, not 2014.'"

Report: Verizon Claimed Public Utility Status To Get Government Perks

samzenpus posted about 6 months ago | from the best-of-both-worlds dept.

Verizon 140

An anonymous reader writes "Research for the Public Utility Law Project (PULP) has been released which details 'how Verizon deliberately moves back and forth between regulatory regimes, classifying its infrastructure either like a heavily regulated telephone network or a deregulated information service depending on its needs. The chicanery has allowed Verizon to raise telephone rates, all the while missing commitments for high-speed internet deployment' (PDF). In short, Verizon pushed for the government to give it common carrier privileges under Title II in order to build out its fiber network with tax-payer money. Result: increased service rates on telephone users to subsidize Verizon's 'infrastructure investment.' When it comes to regulations on Verizon's fiber network, however, Verizon has been pushing the government to classify its services as that of information only — i.e., beyond Title II. Verizon has made about $4.4 billion in additional revenue in New York City alone, 'money that's funneled directly from a Title II service to an array of services that currently lie beyond Title II's reach.' And it's all legal. An attorney at advocacy group Public Knowledge said it best: 'To expect that you can come in and use public infrastructure and funds to build a network and then be free of any regulation is absurd....When Verizon itself is describing these activities as a Title II common carrier, how can the FCC look at broadband internet and continue acting as though it's not a telecommunication network?'"

Shrinking Waves May Save Antarctic Sea Ice

sciencehabit (1205606) writes "It's a nagging thorn in the side of climatologists: Even though the world is warming, the average area of the sea ice around Antarctica is increasing. Climate models haven't explained this seeming contradiction to anyone's satisfaction—and climate change deniers tout that failure early and often. But a new paper suggests a possible explanation: Variability in the heights of ocean waves pounding into the sea ice may help control its advance and retreat."
