Lessons Learned From Google's Green Energy Bust

slashdot.org - dj, 20/11/2014 - 16:02
the_newsbeagle writes In 2007, Google boldly declared a new initiative to invent a green energy technology that produced cheaper electricity than coal-fired power plants. Sure, energy researchers had been hammering at this task for decades, but Google hoped to figure it out in a few years. They didn't. Instead, Google admitted defeat and shut down the project in 2011. In a admirable twist, however, two of the project's engineers then dedicated themselves to learning from the project's failure. What did it mean that one of the world's most ambitious and capable innovation companies couldn't invent a cheap renewable energy tech?

WhatsApp To Offer End-to-End Encryption

slashdot.org - dj, 20/11/2014 - 15:20
L-One-L-One (173461) writes In a surprise move, nine months after being bought by Facebook, WhatsApp has begun rolling out end-to-end encryption for its users. With true end-to-end encryption data becomes unaccessible to admins of WhatsApp or law enforcement authorities. This new feature first proposed on Android only has been developed in cooperation with Open Whisper Systems, based on TextSecure. With hundreds of million users, WhatsApp becomes by far the largest secure messaging application. FBI Director James Comey might not be pleased. Do you have a current favorite for encrypted online chat?

US Gov't Seeks To Keep Megaupload Assets Because Kim Dotcom Is a Fugitive

slashdot.org - dj, 20/11/2014 - 14:49
mrspoonsi writes with this excerpt from Billboard: 'On Tuesday, the U.S. Department of Justice told a Virginia federal judge that Kim Dotcom and cohorts have no business challenging the seizure of an estimated $67 million in assets because the Megaupload founder is evading prosecution. The government brought criminal charges against Dotcom in early 2012, but he's been holed up in New Zealand awaiting word on whether he'll be extradited. The government got antsy and this past July, brought a civil complaint for forfeiture in rem, a maneuver to firmly establish a hold over money from bank accounts around the world, luxury cars, big televisions, watches, artwork and other property allegedly gained by Megaupload in the course of crimes. Dotcom is fighting the seizures by questioning the government's basis for asserting a crime, saying "there is no such crime as secondary criminal copyright infringement," as well as challenging how the seized assets are tied to the charges against Dotcom. But according to the U.S. government, Dotcom doesn't get the pleasure of even making the arguments. In a motion to strike, the government cites the doctrine of fugitive disentitlement, which bars a person from using the resources of the court if that person is aware of prosecution and is evading it.

Millions of Spiders Seen In Mass Dispersal Event In Nova Scotia

slashdot.org - dj, 20/11/2014 - 11:37
Freshly Exhumed writes A bizarre and oddly beautiful display of spider webs have been woven across a large field along a walking trail in Cape Breton, Nova Scotia, Canada. "Well it's acres and acres; it's a sea of web," said Allen McCormick. Prof. Rob Bennett, an expert on spiders who works at the Royal British Columbia Museum in Victoria, BC, Canada, said tiny, sheet-web weaver spiders known as Erigoninae linyphiidae most likely left the webs. Bennett said the spiders cast a web net to catch the wind and float away in a process known as ballooning. The webs in the field are the spiders' drag lines, left behind as they climb to the top of long grass to be whisked away by the wind. Bennett said it's a mystery why these spiders take off en masse.

BitTorrent Unveils Sync 2.0

slashdot.org - dj, 20/11/2014 - 09:02
An anonymous reader writes BitTorrent today outlined the company's plans for its file synchronization tool Sync. Next year, the company will launch Sync 2.0, finally taking the product out of beta, as well as three new paid Sync products. Ever since its debut, Sync has provided a wide variety of solutions to various problems, BitTorrent says, from distributing files across remote servers to sharing vacation photos. BitTorrent thus believes it needs to build three distinct products for each of these separate audiences, including a Pro version for $40 per year.

Android Botnet Evolves, Could Pose Threat To Corporate Networks

slashdot.org - dj, 20/11/2014 - 06:34
angry tapir writes An Android Trojan program that's behind one of the longest running multipurpose mobile botnets has been updated to become stealthier and more resilient. The botnet is mainly used for instant message spam and rogue ticket purchases, but it could be used to launch targeted attacks against corporate networks because the malware allows attackers to use the infected devices as proxies, according to security researchers.

What Would Have Happened If Philae Were Nuclear Powered?

slashdot.org - dj, 20/11/2014 - 04:03
StartsWithABang writes After successfully landing on a comet with all 10 instruments intact, but failing to deploy its thrusters and harpoons to anchor onto the surface, Philae bounced, coming to rest in an area with woefully insufficient sunlight to keep it alive. After exhausting its primary battery, it went into hibernation, most likely never to wake again. We'll always be left to wonder what might have been if it had functioned optimally, and given us years of data rather than just 60 hours worth. The thing is, it wouldn't have needed to function optimally to give us years of data, if only it were better designed in one particular aspect: powered by Plutonium-238 instead of by solar panels.

Blowing On Money To Tell If It Is Counterfeit

slashdot.org - dj, 20/11/2014 - 02:05
HughPickens.com writes Scientific American reports that simply breathing on money could soon reveal if it's the real deal or counterfeit thanks to a photonic crystal ink developed by Ling Bai and Zhongze Gu and colleagues at Southeast University in Nanjing, China that can produce unique color changing patterns on surfaces with an inkjet printer system which would be extremely hard for fraudsters to reproduce. The ink mimics the way Tmesisternus isabellae – a species of longhorn beetle – reversibly switches its color from gold to red according to the humidity in its environment. The color shift is caused by the adsorption of water vapor in their hardened front wings, which alters the thickness and average refractive index of their multilayered scales. To emulate this, the team made their photonic crystal ink using mesoporous silica nanoparticles, which have a large surface area and strong vapor adsorption capabilities that can be precisely controlled. The complicated and reversible multicolor shifts of mesoporous CPC patterns are favorable for immediate recognition by naked eyes but hard to copy. "We think the ink's multiple security features may be useful for antifraud applications," says Bai, "however we think the technology could be more useful for fabricating multiple functional sensor arrays, which we are now working towards."

Court Shuts Down Alleged $120M Tech Support Scam

slashdot.org - dj, 20/11/2014 - 01:25
wiredmikey writes A federal court has temporarily shut down and frozen the assets of two telemarketing operations accused by the FTC of scamming customers out of more than $120 million by deceptively marketing computer software and tech support services. According to complaints filed by the FTC, since at least 2012, the defendants used software designed to trick consumers into believing there were problems with their computers and then hit them with sales pitches for tech support products and services to fix their machines. According to the FTC, the scams began with computer software that claimed to improve the security or performance of the customer's computer. Typically, consumers downloaded a free, trial version of the software that would run a computer system scan. The scan always identified numerous errors, whether they existed or not. Consumers were then told that in order to fix the problems they had to purchase the paid version of the software for between $29 and $49. In order to activate the software after the purchase, consumers were then directed to call a toll-free number and connected to telemarketers who tried to sell them unneeded computer repair services and software, according to the FTC complaint. The services could cost as much as $500, the FTC stated.

Firefox Signs Five-Year Deal With Yahoo, Drops Google as Default Search Engine

slashdot.org - dj, 20/11/2014 - 00:43
mpicpp writes with news that Yahoo will soon become the default search engine in Firefox. Google's 10-year run as Firefox's default search engine is over. Yahoo wants more search traffic, and a deal with Mozilla will bring it. In a major departure for both Mozilla and Yahoo, Firefox's default search engine is switching from Google to Yahoo in the United States. "I'm thrilled to announce that we've entered into a five-year partnership with Mozilla to make Yahoo the default search experience on Firefox across mobile and desktop," Yahoo Chief Executive Marissa Mayer said in a blog post Wednesday. "This is the most significant partnership for Yahoo in five years." The change will come to Firefox users in the US in December, and later Yahoo will bring that new "clean, modern and immersive search experience" to all Yahoo search users. In another part of the deal, Yahoo will support the Do Not Track technology for Firefox users, meaning that it will respect users' preferences not to be tracked for advertising purposes. With millions of users who perform about 100 billion searches a year, Firefox is a major source of the search traffic that's Google's bread and butter. Some of those searches produce search ads, and Mozilla has been funded primarily from a portion of that revenue that Google shares. In 2012, the most recent year for which figures are available, that search revenue brought in the lion's share of Mozilla's $311 million in revenue.

The Software Big Oil's PR Firm Uses To "Convert Average Citizens"

merbs writes The CEO of the world's largest PR firm has a policy when it comes to campaigns that focus on the environment. "We do not work with astroturf groups and we have never created a website for a client with the intent to deny climate change," Richard Edelman wrote in a blog post in August. That may actually turn out to be true. Technically. Edelman may not work with astroturf groups. Instead, it appears to prefer to build them itself, from the ground up, using sophisticated proprietary software platform designed to "convert" advocates and then "track" their behavior.

[Blog] FSFE comments at European Parliament's DG ITEC conference

fsfeurope.org news - dj, 20/11/2014 - 00:00
At a meeting in the European Parliament, FSFE's president Karsten Gerloff highlighted several ways in which the Parliament could become more transparent, and make better use of Free Software and Open Standards. In a short intervention, he urged the Parliament to finally make its live streams accessible to Free Software users. He asked the Parliament's IT administration to enable IMAP access on its mail servers to allow Free Software users to connect through standard protocols, and warned the Parliament to avoid lock-in as it progresses towards greater digitisation.

Congress Suggests Moat, Eletronic Fence To Protect White House

slashdot.org - dc, 19/11/2014 - 23:40
PolygamousRanchKid writes Acting Secret Service director Joseph Clancy on Wednesday faced a number of tough questions from the House Judiciary Committee about the fence jumper who made it deep into the White House. But along with the tough questions, Clancy fielded a couple eyebrow raising suggestions on how to better protect the president's home. "Would a moat, water six feet around, be kind of attractive and effective?" Rep. Steve Cohen, D-Tenn., asked with trepidation. Rep. Louie Gohmert, R-Texas, asked: “Would you be in favor of removing the fence around the White House and having, maybe, a virtual or electronic fence around it?” Clancy liked the moat idea better than the electric fence. “My knee-jerk reaction to that would be no, sir,” he told Gohmert. “Partly because of the number of tourists that come up Pennsylvania Avenue and come up to that area.”

Is a Moral Compass a Hindrance Or a Help For Startups?

slashdot.org - dc, 19/11/2014 - 23:20
Nerval's Lobster writes As an emerging company in a hotly contested space, Uber already had a reputation for playing hardball with competitors, even before reports leaked of one of its executives threatening to dig into the private lives of journalists. Faced with a vicious competitive landscape, Uber executives probably feel they have little choice but to plunge into multi-front battle. As the saying goes, when you're a hammer, everything looks like a nail; and when you're a startup that thinks it's besieged from all sides by entities that seem determined to shut you down, sometimes your executives feel the need to take any measure in order to keep things going, even if those measures are ethically questionable. As more than one analyst has pointed out, Uber isn't the first company in America to triumph through a combination of grit and ethically questionable tactics; but it's also not the first to implode thanks to the latter. Is a moral compass (or at least the appearance of one) a hindrance or a help for startups?

Nielsen Will Start Tracking Netflix and Amazon Video

slashdot.org - dc, 19/11/2014 - 22:38
An anonymous reader writes Nielsen is going to start studying the streaming behavior of online viewers for the first time. Netflix has never released detailed viewership data, but Nielsen says they have developed a way for its rating meters to track shows by identifying their audio. From the article: "Soon Nielsen, the standard-bearer for TV ratings, may change that. The TV ratings company revealed to the Wall Street Journal that it's planning to begin tracking viewership of online video services like Netflix and Amazon Prime Instant Video in December by analyzing the audio of shows that are being streamed. The new ratings will come with a lot of caveats—they won't track mobile devices and won't take into account Netflix's large global reach—but they will provide a sense for the first time which Netflix shows are the most popular. And if the rest of the media world latches onto these new ratings as a standard, Netflix won't be able to ignore them."

CMI Director Alex King Talks About Rare Earth Supplies (Video)

slashdot.org - dc, 19/11/2014 - 21:57
CMI in this context is the Critical Materials Institute at the Iowa State Ames Laboratory in Ames, Iowa. They have partners from other national laboratories, universities, and industry, too. Rare earths, while not necessarily as rare as the word "rare" implies, are hard to mine, separate, and use. They are often found in parts per million quantities, so it takes supercomputers to suss out which deposits are worth going after. This is what Dr. King and his coworkers spend their time doing; finding concentrations of rare earths that can be mined and refined profitably. On November 3 we asked you for questions to put to Dr. King. Timothy incorporated some of those questions into the conversation in this video -- and tomorrow's video too, since we broke this into two parts because, while the subject matter may be fascinating, we are supposed to hold video lengths down to around 10 minutes, and in this case we still ended up with two videos close to 15 minutes each. And this stuff is important enough that instead of lining up a list of links, we are giving you one link to Google using the search term "rare earths." Yes, we know Rare Earth would be a great name for a rock band. But the mineral rare earths are important in the manufacture of items from strong magnets to touch screens and rechargeable batteries.

Number of Coders In Congress To Triple (From One To Three)
