Amazon To Buy Twitch For $970 Million

Slashdot - Tue, 08/26/2014 - 14:04
Dave Knott (2917251) writes Amazon has agreed to acquire the live game-streaming service Twitch for approximately $970 million in cash, a move that could help Amazon bolster its position in the fast-growing business of online gaming and give it technology to compete with video-streaming rivals Netflix and YouTube. The acquisition, which has been approved by Twitch's shareholders, is expected to be completed by the end of the year. Google had for some time been reported to have interest in acquiring Twitch, but those talks cooled in recent weeks. Google was unable to close the deal, said sources familiar with the talks, because it was concerned about potential antitrust issues that could have come with the acquisition.

Net Neutrality Is 'Marxist,' According To a Koch-Backed Astroturf Group

Slashdot - Tue, 08/26/2014 - 11:16
Jason Koebler (3528235) writes American Commitment, a conservative group with strong ties to the Koch brothers has been bombarding inboxes with emails filled with disinformation and fearmongering in an attempt to start a "grassroots" campaign to kill net neutrality — at one point suggesting that "Marxists" think that preserving net neutrality is a good idea. American Commitment president Phil Kerpen suggests that reclassifying the internet as a public utility is the "first step in the fight to destroy American capitalism altogether" and says that the FCC is plotting a "federal Internet takeover," a move that "sounds more like a story coming out of China or Russia."

Early Bitcoin User Interviewed By Federal Officers

Slashdot - Tue, 08/26/2014 - 09:18
MrBingoBoingo (3481277) writes Recently a Bitcoin user reports being interviewed over their past use of a now defuct exchange service by agents from the FBI and Treasury Department. This encounter raises concerns that earlier Bitcoin users who entered the space inocuously and without ties to Dark Markets or The Silk Road might need to prepare for Law Enforcement questioning about their early Bitcoin related activities.

Predictive Modeling To Increase Responsivity of Streamed Games

Slashdot - Tue, 08/26/2014 - 05:54
jones_supa (887896) writes Streaming game services always bump up against a hard latency limit based on the total round-trip time it takes to send user input to a remote server and receive a frame of game data from that server. To alleviate the situation, Microsoft Research has been developing a system called DeLorean (whitepaper) using predictive modeling to improve the experienced responsiveness of a game. By analyzing previous inputs in a Markov chain, DeLorean tries to predict the most likely choices for the user's next input and then generates speculative frames that fit those inputs and sends them back to the user. The caveat is that sending those extra predictive frames and information does add a bandwidth overhead of anywhere from 1.5 to 4 times that of a normal streaming game client. During testing the benefits were apparent, though. Even when the actual round-trip time between input and server response was 256 ms, double-blind testers reported both the gameplay responsiveness and graphical quality of the DeLorean system were comparable to a locally played version of the game.

Why Do Humans Grow Up So Slowly? Blame the Brain

Slashdot - Tue, 08/26/2014 - 04:03
sciencehabit (1205606) writes Humans are late bloomers when compared with other primates — they spend almost twice as long in childhood and adolescence as chimps, gibbons, or macaques do. But why? One widely accepted but hard-to-test theory is that children's brains consume so much energy that they divert glucose from the rest of the body, slowing growth. Now, a clever study of glucose uptake and body growth in children confirms this 'expensive tissue' hypothesis.

850 Billion NSA Surveillance Records Searchable By Domestic Law Enforcement

Slashdot - Tue, 08/26/2014 - 01:15
onproton (3434437) writes The Intercept reported today on classified documents revealing that the NSA has built its own "Google-like" search engine to provide over 850 billion collected records directly to law enforcement agencies, including the FBI and the DEA. Reporter Ryan Gallagher explains, "The documents provide the first definitive evidence that the NSA has for years made massive amounts of surveillance data directly accessible to domestic law enforcement agencies." The search engine, called ICREACH, allows analysts to search an array of databases, some of which contain metadata collected on innocent American citizens, for the purposes of "foreign intelligence." However, questions have been raised over its potential for abuse in what is known as "parallel construction," a process in which agencies use surveillance resources in domestic investigations, and then later cover it up by creating a different evidence trail to use in court.

The Evolution of Diet

Slashdot - Tue, 08/26/2014 - 00:35
An anonymous reader writes Here's a story from National Geographic that looks at the historical diets of people from around the world and what that diet might look like in the future. From the article: "So far studies of foragers like the Tsimane, Arctic Inuit, and Hadza have found that these peoples traditionally didn't develop high blood pressure, atherosclerosis, or cardiovascular disease. 'A lot of people believe there is a discordance between what we eat today and what our ancestors evolved to eat,' says paleoanthropologist Peter Ungar of the University of Arkansas. The notion that we're trapped in Stone Age bodies in a fast-food world is driving the current craze for Paleolithic diets. The popularity of these so-called caveman or Stone Age diets is based on the idea that modern humans evolved to eat the way hunter-gatherers did during the Paleolithic—the period from about 2.6 million years ago to the start of the agricultural revolution—and that our genes haven't had enough time to adapt to farmed foods."

NRC Analyst Calls To Close Diablo Canyon, CA's Last Remaining Nuclear Plant

Slashdot - Mon, 08/25/2014 - 23:51
An anonymous reader writes Michael Peck, who for five years was Diablo Canyon's lead on-site inspector, says in a 42-page, confidential report that the Nuclear Regulatory Commission is not applying the safety rules it set out for the plant's operation. The document, which was obtained and verified by The Associated Press, does not say the plant itself is unsafe. Instead, according to Peck's analysis, no one knows whether the facility's key equipment can withstand strong shaking from those faults — the potential for which was realized decades after the facility was built. Continuing to run the reactors, Peck writes, "challenges the presumption of nuclear safety."

Whole Organ Grown In Animal For First Time

Slashdot - Mon, 08/25/2014 - 22:20
An anonymous reader writes British scientists have produced the first working organ grown from scratch in a living animal. Reprogrammed cells created in a lab were used in a mouse to produce a thymus. The organ was created using connective tissue cells from a mouse embryo and were converted into a different cell strain by changing a genetic switch in their DNA. The resulting cells grew into the whole organ after being injected. It has only been tested on mice so far, but researchers at Edinburgh University say that within a decade the procedure could be effective and safe enough for humans. The findings were published in Nature Cell Biology.

Is Dong Nguyen Trolling Gamers With "Swing Copters"?

Slashdot - Mon, 08/25/2014 - 21:37
Nerval's Lobster writes Given its extreme difficulty, it's tempting to think that the new Swing Copters is Dong Nguyen's attempt at a joke (You thought 'Flappy Bird' was hard? Check this out!), or maybe even a meta-comment on the emerging "masocore" gaming category. Or maybe he just wanted to make another game, and the idea of an ultra-difficult one appealed. Whatever the case, Nguyen can rely on the enduring popularity of Flappy Bird to propel Swing Copters to the top of the Google and iOS charts. But his games' popularity illuminates a rough issue for developers of popular (or even just semi-popular) apps everywhere: how do you deal with all the copycats flooding the world's app stores? Although Google and Apple boast that their respective app stores feature hundreds of thousands of apps, sometimes it seems as if most of those apps are crude imitations of other apps. The perpetual fear among app developers is that they'll score a modest hit—only to see their years of hard work undermined by someone who cobbles together a clone in a matter of weeks or days. If Apple and Google want to make things friendlier out there for developers, they might consider stricter enforcement policies for the blatant rip-offs filling their digital storefronts.

Choose Your Side On the Linux Divide

Slashdot - Mon, 08/25/2014 - 20:54
snydeq writes The battle over systemd exposes a fundamental gap between the old Unix guard and a new guard of Linux developers and admins, writes Deep End's Paul Venezia. "Last week I posted about the schism brewing over systemd and the curiously fast adoption of this massive change to many Linux distributions. If there's one thing that systemd does extremely well, it is to spark heated discussions that devolve into wild, teeth-gnashing rants from both sides. Clearly, systemd is a polarizing subject. If nothing else, that very fact should give one pause. Fundamental changes in the structure of most Linux distributions should not be met with such fervent opposition. It indicates that no matter how reasonable a change may seem, if enough established and learned folks disagree with the change, then perhaps it bears further inspection before going to production. Clearly, that hasn't happened with systemd."

Numerous Methane Leaks Found On Atlantic Sea Floor

Slashdot - Mon, 08/25/2014 - 20:08
sciencehabit writes Researchers have discovered 570 plumes of methane percolating up from the sea floor off the eastern coast of the United States, a surprisingly high number of seeps in a relatively quiescent part of the ocean. The seeps suggest that methane's contribution to climate change has been underestimated in some models. And because most of the seeps lie at depths where small changes in temperature could be releasing the methane, it is possible that climate change itself could be playing a role in turning some of them on.

Systems That Can Secretly Track Where Cellphone Users Go Around the Globe

Slashdot - Mon, 08/25/2014 - 18:40
cold fjord writes with this story about the proliferation of companies willing to sell tracking information and systems. Makers of surveillance systems are offering governments across the world the ability to track the movements of almost anybody who carries a cellphone, whether they are blocks away or on another continent. The technology works by exploiting an essential fact of all cellular networks: They must keep detailed, up-to-the-minute records on the locations of their customers to deliver calls and other services to them. Surveillance systems are secretly collecting these records to map people's travels over days, weeks or longer ... It is unclear which governments have acquired these tracking systems, but one industry official ... said that dozens of countries have bought or leased such technology in recent years. This rapid spread underscores how the burgeoning, multibillion-dollar surveillance industry makes advanced spying technology available worldwide. "Any tin-pot dictator with enough money to buy the system could spy on people anywhere in the world," said Eric King, deputy director of Privacy International.

Robo Brain Project Wants To Turn the Internet Into a Robotic Hivemind

Slashdot - Mon, 08/25/2014 - 17:55
malachiorion writes Researchers are force-feeding the internet into a system called Robo Brain. The system has absorbed a billion images and 120,000 YouTube videos so far, and aims to digest 10 times that within a year, in order to create machine-readable commands for robots—how to pour coffee, for example. From the article: "The goal is as direct as the project’s name—to create a centralized, always-online brain for robots to tap into. The more Robo Brain learns from the internet, the more direct lessons it can share with connected machines. How do you turn on a toaster? Robo Brain knows, and can share 3D images of the appliance and the relevant components. It can tell a robot what a coffee mug looks like, and how to carry it by the handle without dumping the contents. It can recognize when a human is watching a television by gauging relative positions, and advise against wandering between the two. Robo Brain looks at a chair or a stool, and knows that these are things that people sit on. It’s a system that understands context, and turns complex associations into direct commands for physical robots."

Put A Red Cross PSA In Front Of the ISIS Beheading Video

Slashdot - Mon, 08/25/2014 - 17:10
Bennett Haselton writes After footage of James Foley's beheading by ISIS terrorists was posted online on Tuesday, Twitter and Youtube elected to remove any footage or links to the footage posted by users. Obviously this reduces the incentive for terrorist groups to post such content, by shrinking their audience, but it also reduces the public's access to information. Would it be ethical to make the content available, if it was preceded by an advertisement for a cause that runs counter to everything ISIS stands for? Read below to see what Bennett has to say.

Thanks to the work of four North Carolina State University undergrads, you'll soon be able to find out without reaching for a testing tool. That's because you'll already have five of them on each hand. The team — Ankesh Madan, Stephen Gray, Tasso Von Windheim, and Tyler Confrey-Maloney — has come up with a creative and unobtrusive way to package chemicals that react when exposed to Rohypnol and GHB. They put it in nail polish that they're calling Undercover Colors.
