Petaflops? DARPA Seeks Quintillion-Flop Computers
coondoggie writes "Not known for taking the demure route, researchers at DARPA this week announced a program aimed at building computers that exceed current peta-scale computers to achieve the mind-altering speed of one quintillion (1,000,000,000,000,000,000) calculations per second. Dubbed extreme scale computing, such machines are needed, DARPA says, to 'meet the relentlessly increasing demands for greater performance, higher energy efficiency, ease of programmability, system dependability, and security.'"

Why Being Wrong Makes Humans So Smart
Hugh Pickens sends in an excerpt in last week's Boston Globe from Kathryn Schulz's book Being Wrong: Adventures in the Margin of Error. "The more scientists understand about cognitive functioning, the more it becomes clear that our capacity to make mistakes is utterly inextricable from what makes the human brain so swift, adaptable, and intelligent. Rather than treating errors like the bedbugs of the intellect — an appalling and embarrassing nuisance we try to pretend out of existence — we need to recognize that human fallibility is part and parcel of human brilliance. Neuroscientists increasingly think that inductive reasoning undergirds virtually all of human cognition. Humans use inductive reasoning to learn language, organize the world into meaningful categories, and grasp the relationship between cause and effect. Thanks to inductive reasoning, we are able to form nearly instantaneous beliefs and take action accordingly. However, Schulz writes, 'The distinctive thing about inductive reasoning is that it generates conclusions that aren't necessarily true. They are, instead, probabilistically true — which means they are possibly false.' Schulz recommends that we respond to the mistakes (or putative mistakes) of those around us with empathy and generosity and demand that our business and political leaders acknowledge and redress their errors rather than ignoring or denying them. 'Once we recognize that we do not err out of laziness, stupidity, or evil intent, we can liberate ourselves from the impossible burden of trying to be permanently right. We can take seriously the proposition that we could be in error, without deeming ourselves idiotic or unworthy.'"

Congressman Tells BP Exec That Other Cultures Would Demand His Suicide
During a hearing before a subpanel of the House Energy and Commerce Committee, Rep. Cliff Stearns told BP America President Lamar McKay, "Well, in the Asian culture we do things differently. During the Samurai days, we just give you a knife and ask you to commit harakiri." I'm sure Mr. McKay expected to get his fair share of grief at the hearing, but I bet he never thought it would be suggested that he commit ritual suicide.

FSF Starts Anti-ACTA Campaign
judgecorp writes "Free Software Foundation president Richard Stallman has said in a blog post that the ACTA file-sharing proposals punish users unfairly. He wrote, 'Any time there is a proposal to change things for the worse, the obvious way to oppose it is to campaign for the status quo. To campaign for the status quo suggests the approach of singing its praises; thus, praising WIPO is a natural way to highlight how ACTA is a step for the worse. However, where there have been previous changes for the worse, lauding the status quo tends to legitimize them. The past 20 years have seen global waves of harmful changes in copyright law — some promoted by WIPO. To confront a further assault by presenting the status quo as ideal means we stop fighting to reverse them. It means that our adversaries need only propose a further affront to our rights to gain our acceptance of their last affront. Instead of making the status quo our ideal, we should demand positive changes to recover freedoms already lost.' The FSF has launched a petition against the ACTA proposals."

Set Free Your Inner Jedi (Or Pyro)
sirgoran writes "We've all thought about being the hero fighting off evil-doers and saving the day ever since we first saw Star Wars. The folks at Wicked Lasers have now brought that a little closer to reality with their latest release: a 1-Watt blue diode laser that can set skin and other things on fire. From an article at Daily Tech, where they talk about the dangers of such a powerful laser: 'And here's the best (or worst) part — it can set people (or things) on fire. Apparently the laser is so high-powered that shining it on fleshy parts will cause them to burst into flames. Of course it's equally capable of blinding people.' The thing that caught my eye was the price: $200. I wonder if they'll be able to meet the demand, since (if it works as advertised) this will be on every geek's Christmas list."

What Gamers Have In Common With Top Athletes
nk497 writes "It's no surprise that professional gamers aren't quite as fit as elite athletes, but they do have something in common. According to a British academic, top-level players show similar psychological attributes as top athletes, such as the ability to manage anxiety, and have reaction times on par with fighter pilots. Dr. Micklewright said, 'When I first got asked to do [the study], my initial reaction was "don't be ridiculous, gaming is nothing like sport." But the more I thought about it, the more similarities [became clear], and I became more and more convinced that it was close in many ways to sport.' While sitting in front of a screen might not have the same physical demands as running a marathon, neither do playing snooker or darts. Still, while gamers show good reflexes, their health was worse than expected, with one 20-something professional player showing the same aerobic health as a 60-year-old smoker." This story is based on a BBC radio report which you can currently hear, although that link seems to say that it won't last.

Canada's Largest Cities Seeing the End of the Phone Book
innocent_white_lamb writes "Telephone directories are available on the Internet, and many phones even store their own directories. There is less and less demand for a printed phone book, so residential phone books will no longer be printed and delivered in Canada's seven largest cities. Do we now expect everyone's grandma to look up phone numbers on the Internet? Of course, the Yellow Pages, where businesses pay for a listing, will still be delivered."

Google Relents, Will Hand Over European Wi-Fi Data
itwbennett writes "Having previously denied demands from Germany that the company turn over hard drives with data it secretly collected from open wireless networks over the past three years, Google has reversed course. A Google representative said that it will hand over the data to German, French, and Spanish authorities within a matter of days, according to the Financial Times, which first reported this latest development on Wednesday. 'We screwed up. Let's be very clear about that,' Google CEO Eric Schmidt told the newspaper."

Clashing Scores In the HTML5 Compatibility Test Wars
Andreas(R) writes "Microsoft has published a set of HTML5 tests comparing Internet Explorer 9 to other web browsers. In Microsoft's own tests, IE9 performs 100% on all tests. However, the Internet Explorer 9 HTML5 Canvas Campaign has published results that show that Internet Explorer gets 0% on all their tests." The results reported here are selected with tongue in cheek: "Therefore, we'll also present shameless results from tests which have been carefully selected to give the results that the PR department has demanded."

Bangladesh Blocks Facebook Over Muhammad Cartoons
lbalbalba writes with a BBC story about Bangladesh following Pakistan in censoring Facebook. "Bangladesh has blocked access to Facebook after satirical images of the prophet Muhammad and the country's leaders were uploaded. One man has been arrested and charged with 'spreading malice and insulting the country's leaders' with the images. Officials said the ban was temporary and access to the site would be restored once the images were removed. It comes after Pakistan invoked a similar ban over 'blasphemous content.' ... Thousands of people joined anti-Facebook protests in Bangladesh on Friday demanding the site be blocked over the contest. A telecomm regulator there said, "Facebook will be re-opened once we erase the pages that contain the obnoxious images." And how do they propose to do that?

German Publishers Want Censorship Talks With Apple
An anonymous reader writes "The association of German magazine publishers has sent a letter to Steve Jobs (Google translation; German original here) demanding talks about censorship by Apple. The move draws attention to growing concerns about freedom of the press when a single unelected commercial entity has worldwide control over what gets published for the iPhone and, especially, the iPad." While the magazine publishers may rightly be concerned about private control of a platform that many of them are counting on for their long-term salvation, the German state is at the very least ambivalent about the subject of censorship. This is the country that has banned Wikileaks, sought a ban on violent games, and voted to censor child porn (only to have the president kill the ban as unconstituitonal).

When Mistakes Improve Performance
jd and other readers pointed out BBC coverage of research into "stochastic" CPUs that allow communication errors in order to reap benefits in performance and power usage. "Professor Rakesh Kumar at the University of Illinois has produced research showing that allowing communication errors between microprocessor components and then making the software more robust will actually result in chips that are faster and yet require less power. His argument is that at the current scale, errors in transmission occur anyway and that the efforts of chip manufacturers to hide these to create the illusion of perfect reliability simply introduces a lot of unnecessary expense, demands excessive power, and deoptimises the design. He favors a new architecture, that he calls the 'stochastic processor,' which is designed to handle data corruption and error recovery gracefully. He believes he has shown such a design would work and that it would permit Moore's Law to continue to operate into the foreseeable future. However, this is not the first time someone has tried to fundamentally revolutionize the CPU. The Transputer, the AMULET, the FM8501, the iWARP, and the Crusoe were all supposed to be game-changers but died cold, lonely deaths instead — and those were far closer to design philosophies programmers are currently familiar with. Modern software simply isn't written with the level of reliability the stochastic processor requires (and many software packages are too big and too complex to port), and the volume of available software frequently makes or breaks new designs. Will this be 'interesting but dead-end' research, or will Professor Kumar pull off a CPU architectural revolution really not seen since the microprocessor was designed?"

Japan Moves Toward Blocking Online Child Porn
crimeandpunishment writes "In the wake of increased international demands that it do something about its legal lenience toward child pornography, Japan is beginning to take action, albeit slowly. Thursday a government task force recommended that kiddie porn sites be blocked as soon as they're discovered, instead of waiting for an investigation or arrests. Making or distributing child porn is illegal in Japan, but possession is not ... and critics have called that a legal loophole making Japan an international hub for child porn."

Sudden Demand For Logicians On Wall Street
An anonymous reader writes "In an unexpected development for the depressed market for mathematical logicians, Wall Street has begun quietly and aggressively recruiting proof theorists and recursion theorists for their expertise in applying ordinal notations and ordinal collapsing functions to high-frequency algorithmic trading. Ordinal notations, which specify sequences of ordinal numbers of ever increasing complexity, are being used by elite trading operations to parameterize families of trading strategies of breathtaking sophistication. The monetary advantage of the current strategy is rapidly exhausted after a lifetime of approximately four seconds — an eternity for a machine, but barely enough time for a human to begin to comprehend what happened. The algorithm then switches to another trading strategy of higher ordinal rank, and uses this for a few seconds on one or more electronic exchanges, and so on, while opponent algorithms attempt the same maneuvers, risking billions of dollars in the process."

Data Center Building Boom In Silicon Valley
1sockchuck writes "Data center developers are building like mad in Silicon Valley, with seven active projects in Santa Clara alone. The building boom includes the resumption of several stalled projects that prompted concerns of a shortage of wholesale data center space in the Valley. The flurry of construction activity is different from the overbuilding during the dot-com boom, which was characterized by too much funding and too few customers. This time, industry experts say, the end of a funding drought has created a situation in which construction is struggling to stay ahead of demand from companies like Facebook — which just scarfed up an entire new data center in Santa Clara."

Toyota Partners With Tesla To Make Electric Cars
An anonymous reader writes "Toyota just announced that it will invest $50 million in Tesla Motors and the two companies will partner to manufacture electric vehicles to meet California's growing demand for greener cars. Bay Area residents should be especially excited, as this venture is expected to create thousands of new jobs in the San Francisco Bay area, and is sure to be a boon to California's flagging economy. Tesla fans as well should rejoice as the new partnership will allow the EV startup to bring its highly coveted, iconic design to more affordable electric vehicles like the Model S sedan, which will sell for $49,900 and gets 300 miles on a 3- to 5-hour charge."

Apple Reverses iPad "No Cash Purchase" Policy
ZipK writes "After a few days of bad publicity, Apple has reversed its no cash purchase policy, explaining that the policy was originally implemented to limit the number of iPads an individual could buy during the introductory period of short supply. Now that supply has caught up with demand — and the story has hit front pages and gained national attention — Apple has reversed its policy, and taken the opportunity to put a bow on the story by giving the formerly scorned Diane Campbell a free iPad."

Germany Demands Google Forfeit Citizens' Wi-Fi Data
eldavojohn writes "Germany has ordered Google to give up hard disk drives used to store German data collected during their Street View operations in that country. This follows Google's admission last week (after prodding from the Germans) that it had collected the data from unsecured wireless area networks from around the entire world as its roving cars collected the photo archive for Street View. Google says they've offered to just destroy the data, in cooperation with national regulators, but the German government wants to know what they've collected. They do not think that destroying the drives suffices for compliance with the laws. Officials went so far as to say of the situation, 'It is not acceptable that a company operating in the EU does not respect EU rules.' Germany has certainly been keeping their eye on the search giant." The Ars coverage notes that the US FTC may be looking more closely at Google's collection as well.

In UK, Hacker Demands New Government Block Extradition
Stoobalou writes "Pentagon hacker Gary McKinnon has called on the newly elected British government to put its money where its mouth is and tear up his extradition order. US prosecutors have been trying to get McKinnon before a New Jersey court for seven years after they caught him hacking into US military and NASA computers looking for evidence of UFOs. David Cameron, the newly elected prime minister, and Nick Clegg, the deputy prime minister, had both voiced their support for McKinnon's campaign against extradition. Other ministers in the coalition government had branded the extradition unjust. Clegg had even joined McKinnon's mother, Janis Sharp, on a protest march."

Developer-Friendly Banks?
tyen writes "Any suggestions for a 'developer-friendly' bank for small businesses? The banking world is awash in data protocols that business customers who are/have coders would find useful, like BAI to extract all the raw data from an ACH or SWIFT transfer. Unfortunately, the ones I have spoken with about this access are still stuck in the Dark Ages of computing; they price the access like only big companies still have the skills to tap into these interfaces. For example, one of the four US banks with a perfect trading record this past quarter quoted us USD five figures for access to several of our accounts via BAI format. Per year. After waiving sign-up fees. Are there any banks out there that have a more progressive attitude about letting small, entrepreneurial developers work with their business accounts in a more modern, dare we say automated, way? With big businesses demanding EFT integration from small business vendors, and globalization rewarding premiums to nimble, lean businesses that automate wherever possible, automating the retrieval of this information (which is not available in consumer-oriented access like OFX) becomes an increasingly pressing issue for the small guys."
