Supercomputing

Does Being First Still Matter In America?

Posted by timothy
from the by-jingo dept.
dcblogs writes At the supercomputing conference, SC14, this week, a U.S. Dept. of Energy offical said the government has set a goal of 2023 as its delivery date for an exascale system. It may be taking a risky path with that amount of lead time because of increasing international competition. There was a time when the U.S. didn't settle for second place. President John F. Kennedy delivered his famous "we choose to go to the moon" speech in 1962, and seven years later a man walked on the moon. The U.S. exascale goal is nine years away. China, Europe and Japan all have major exascale efforts, and the government has already dropped on supercomputing. The European forecast of Hurricane Sandy in 2012 was so far ahead of U.S. models in predicting the storm's path that the National Oceanic and Atmospheric Administration was called before Congress to explain how it happened. It was told by a U.S. official that NOAA wasn't keeping up in computational capability. It's still not keeping up. Cliff Mass, a professor of meteorology at the University of Washington, wrote on his blog last month that the U.S. is "rapidly falling behind leading weather prediction centers around the world" because it has yet to catch up in computational capability to Europe. That criticism followed the $128 million recent purchase a Cray supercomputer by the U.K.'s Met Office, its meteorological agency.

Ask Slashdot: Workaday Software For BSD On the Desktop? 50

Posted by timothy
from the clever-little-devil dept.
An anonymous reader writes So for a variety of reasons (some related to recent events, some ongoing for a while) I've kinda soured on Linux and have been looking at giving BSD a shot on the desktop. I've been a Gentoo user for many years and am reasonably comfortable diving into stuff, so I don't anticipate user friendliness being a show stopper. I suspect it's more likely something I currently do will have poor support in the BSD world. I have of course been doing some reading and will probably just give it a try at some point regardless, but I was curious what experience and advice other slashdot users could share. There's been many bold comments on slashdot about moving away from Linux, so I suspect I'm not the only one asking these questions. Use-case wise, my list of must haves is: Minecraft, and probably more dubiously, FTB; mplayer or equivalent (very much prefer mplayer as it's what I've used forever); VirtualBox or something equivalent; Firefox (like mplayer, it's just what I've always used, and while I would consider alternatives, that would definitely be a negative); Flash (I hate it, but browsing the web sans-flash is still a pain); OpenRA (this is the one I anticipate giving me the most trouble, but playing it is somewhat of an obsession).

Stuff that would be nice but I can live without: Full disk encryption; Openbox / XFCE (It's what I use now and would like to keep using, but I could probably switch to something else without too much grief); jackd/rakarrack or something equivalent (currently use my computer as a cheap guitar amp/effects stack); Qt (toolkit of choice for my own stuff).
What's the most painless way to transition to BSD for this constellation of uses, and which variety of BSD would you suggest?

Apple Swaps "Get" Button For "Free" To Avoid Confusion Over In-App Purchases 54

Posted by timothy
from the for-the-low-low-price dept.
New submitter lazarus (2879) writes Apple is falling in line with the European Commission's request that app sellers do more to stop inadvertent in-app purchases. Following Google's lead, Cupertino has removed all instances of the word "free" within its iOS and Mac app stores (with the exception of its own apps, like iMovie), and replaced them with the term "Get." The new label clarifies what users can expect when downloading an app. Apps previously labeled as "Free" will now have a "Get" label. If those apps include in-app purchases, a small gray "In-App Purchase" label will appear below the "Get" button.

Google Maps Crunches Data, Tells You When To Drive On Thanksgiving 55

Posted by timothy
from the could-have-told-you-that-for-free dept.
Nerval's Lobster writes Whatever your plans for Thanksgiving, Google can offer some advice: try to avoid driving anywhere the day before. Analysts from the search-engine giant's Google Maps division crunched traffic data from 21 U.S. cities over the past two years and found that the Wednesday before Thanksgiving is by far the worst traffic day that week, with some notable exceptions. (In Honolulu, Providence, and San Francisco, the worst traffic is always on Saturday; in Boston, it's Tuesday.) Unfortunately, Wednesday is often the only available travel day for many Americans—but Google thinks they can beat the worst of the traffic if they leave before 2 P.M. or after 7 P.M. on that day. Traffic on Thanksgiving itself is also light, according to the data. When it comes to driving back home, Sunday beats Saturday from a traffic perspective. According to Google Maps' aggregated trends, Americans also seek out "ham shop," "pie shop," and "liquor store" on the day before Thanksgiving, as they rush to secure last-minute items.

Lessons Learned From Google's Green Energy Bust 170

Posted by timothy
from the systems-have-momentum-and-context dept.
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 78

Posted by timothy
from the trend-worth-extending dept.
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?

from the brand-new dept.
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.

What Would Have Happened If Philae Were Nuclear Powered? 439

Posted by samzenpus
from the still-going dept.
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 110

Posted by samzenpus
from the huff-and-puff dept.
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."

Firefox Signs Five-Year Deal With Yahoo, Drops Google as Default Search Engine 353

Posted by samzenpus
from the new-couple dept.
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" 80

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.

Nielsen Will Start Tracking Netflix and Amazon Video 55

Posted by samzenpus
from the tracking-the-numbers dept.
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."

There isn't always an option to stop and fill up from a clean stream or drinking fountain, but water could be obtained from a different source: the air. Austrian industrial design student Kristof Retezár has created Fontus: a prototype of a water bottle system that condenses humid air into clean, drinkable water. His design made him a finalist for the 2014 James Dyson Award.

Three-Way Comparison Shows PCs Slaying Consoles In Dragon Age Inquisition 205

Posted by Soulskill
from the as-expected dept.
MojoKid writes: "BioWare's long-awaited Dragon Age Inquisition has dropped for the PS4, Xbox One, and PCs. A comparison of the visuals in key scenes between all three platforms shows that while the PC variant clearly looks the best in multiple areas (as it should), there's evidence of good, intelligent optimization for consoles and PCs alike. After the debacle of Assassin's Creed Unity, Inquisition could provide an important taste of how to do things right. As expected though, when detail levels are increased, the PC still pulls away with the best overall visuals. The Xbox One and PS4 are largely matched, while PC renders of characters have better facial coloring and slightly more detailed textures. The lighting models are also far more detailed on the PC version with the PS4 following behind. The Xbox One, in contrast, is rather muddy. Overall, the PC and PS4 are closest in general detail, with the Xbox One occasionally lagging behind.

Halting Problem Proves That Lethal Robots Cannot Correctly Decide To Kill Humans 306

Posted by Soulskill
from the guess-we're-back-to-coinflips dept.
KentuckyFC writes: The halting problem is to determine whether an arbitrary computer program, once started, will ever finish running or whether it will continue forever. In 1936, Alan Turing famously showed that there is no general algorithm that can solve this problem. Now a group of computer scientists and ethicists have used the halting problem to tackle the question of how a weaponized robot could decide to kill a human. Their trick is to reformulate the problem in algorithmic terms by considering an evil computer programmer who writes a piece of software on which human lives depend.

The question is whether the software is entirely benign or whether it can ever operate in a way that ends up killing people. In general, a robot could never decide the answer to this question. As a result, autonomous robots should never be designed to kill or harm humans, say the authors, even though various lethal autonomous robots are already available. One curious corollary is that if the human brain is a Turing machine, then humans can never decide this issue either, a point that the authors deliberately steer well clear of.

Head of FCC Proposes Increasing Internet School Fund 103

Rambo Tribble writes: The commissioners at the FCC are expected to vote, on December 11, on a proposal by Chairman Tom Wheeler to increase the funding for the nation's largest educational technology subsidy program, E-Rate, by 62 percent. The proposal is intended to be paid for by higher fees on phone service. The increased cost is pegged at $1.92 a year, per telephone line. Support for the proposal, or lack thereof, appears to be falling along partisan lines. To quote Wheeler, however, "Almost two-thirds of American schools cannot appropriately connect their students to the 21st century."

Microsoft Azure Outage Across the Globe 157

hawkinspeter writes: The BBC reports that overnight an outage of Microsoft's Azure cloud computing platform took down many third-party sites that rely on it, in addition to disrupting Microsoft's own products. Office 365 and Xbox Live services were affected.

This happened at a particularly inopportune time, as Microsoft has recently been pushing its Azure services in an effort to catch up with other providers such as Amazon, IBM, and Google. Just a couple of hours previously, Microsoft had screened an Azure advert in the UK during the Scotland v. England soccer match."

How Facebook Is Influencing Who Will Win the Next Election 71

Posted by Soulskill
from the setting-up-a-scapegoat dept.
An anonymous reader sends this excerpt from Forbes: [Facebook] announced yesterday that it was shutting down a feature that the Obama campaign used in 2012 to register over a million voters. During the election supporters shared access to their list of Facebook friends list with the campaign through an app. Researchers have found that while people view often political messages with skepticism, they are more receptive and trusting when the information is coming from somebody they know. The feature was credited with boosting Obama’s get-out-the-vote efforts which were crucial to his victory, but Facebook has decided to disable this ability in order to (rightfully) protect users from third-party apps collecting too much of their information.

The company insists that it favors no particular ideology and that its efforts are “neutral.” The first part is likely true, but the second is not possible. The company’s algorithms take into account a proprietary mix of our own biases, connections, and interests combined with Facebook’s business priorities; that is the farthest thing from neutral. Facebook says it just want to encourage “civic participation,” but politically mobilizing the subsection of people that are on their network is not without its own impacts.
