LingNoi writes with this excerpt from ComputerWorld UK: "The London Stock Exchange has said its new Linux-based system is delivering world record networking speed, with 126 microsecond trading times. The news comes ahead a major Linux-based switchover in twelve days, during which the open source system will replace Microsoft .Net technology on the group's main stock exchange. The LSE had long been criticised on speed and reliability, grappling with trading speeds of several hundred microseconds. The 126 microsecond speed is 'twice as fast' as its main international competitors, the London Stock Exchange said. BATS Europe and Chi-X, two dedicated electronic rivals to the LSE, are reported to have an average latency of 250 and 175 microseconds respectively. Neither company immediately provided details. But many of the LSE's older and more traditional rivals offer speeds of around 300 to 400 microseconds. Nevertheless, Linux is now standard in many exchanges, including the New York Stock Exchange."

An anonymous reader writes "The People's Daily newspaper, which is the official news organ of the ruling Communist party in China, apparently recently posted a review of the iPad, where it complained about the locked down nature of the device, noting that 'There are many disadvantages. For example you cannot install pirate software on them, you cannot download [free] music, and you need to pay for movies you watch on them.' You would think a country that is in favor of locking down the internet so much would like a locked up device ..."

Attila Dimedici writes "This article says the Chevy Volt is not what GM claimed it was: an Extended Range Electric Vehicle. The Volt is simply a plug-in hybrid. Instead of a vehicle that is only driven with the electric drive train that uses a gasoline engine to charge the batteries, the Volt actually uses the gasoline engine to drive the front wheels at speeds above 70 miles per hour or when the batteries run down. Additionally, the Volt gets nowhere near the 230 mpg that GM was claiming for it. If this is all true, why did GM misrepresent the car? The facts as stated in the article make the Volt a pretty decent competitor to the Prius and other hybrids already on the market." A post at the Car Connection blog takes the opposing view, saying that accusations of GM "lying" are overhyped, since the capability to power the wheels with gasoline is reserved for situations where electricity isn't a viable option. The author says GM didn't mention this ability before now due to concerns over patents and competition from other companies.

mngdih writes with this excerpt from Wired: "A California student got a visit from the FBI this week after he found a secret GPS tracking device on his car, and a friend posted photos of it online. The post prompted wide speculation about whether the device was real, whether the young Arab-American was being targeted in a terrorism investigation and what the authorities would do. It took just 48 hours to find out: The device was real, the student was being secretly tracked and the FBI wanted their expensive device back ... His discovery comes in the wake of a recent ruling by the 9th US Circuit Court of Appeals saying it's legal for law enforcement to secretly place a tracking device on a suspect's car without getting a warrant, even if the car is parked in a private driveway. ... 'We have all the information we needed,' they told him. 'You don't need to call your lawyer. Don't worry, you're boring.'"

Flash Modin writes "In a Scientific American essay based on their new book A Grand Design, Stephen Hawking and Leonard Mlodinow are now claiming physicists may never find a theory of everything. Instead, they propose a 'family of interconnected theories' might emerge, with each describing a certain reality under specific conditions. The claim is a reversal for Hawking, who claimed in 1980 that there would be a unified theory by the turn of the century."

An anonymous reader writes "MIT's technology blog argues that e-book sales represent 'only six pecent of the total market for new books.' It cites a business analysis which calculates that by mid-July, Amazon had sold 15.6 million hardcover books versus 22 million e-books, but with sales of about 48 million more paperback books. Amazon recently announced they sell 180 e-books for every 100 hardcover books, but when paperbacks are counted, e-books represent just 29.3% of all Amazon's book sales. And while Amazon holds about 19% of the book market, they currently represent 90% of all e-book sales — suggesting that e-books represent a tiny fraction of all print books sold. 'Many tech pundit wants books to die,' argues MIT's Christopher Mims, citing the head of Microsoft's ClearType team, who says 'I'd be glad to ditch thousands of paper- and hard-backed books from my bookshelves. I'd rather have them all on an iPad.' But while Nicholas Negroponte predicts the death of the book within five years, Mims argues that 'it's just as likely that as the ranks of the early adopters get saturated, adoption of e-books will slow.'"

The crew is conducting simulated manufacturing and assembly operations with a full-scale Orion mockup to verify the tools, processes and spacecraft integration procedures work as expected."

mspohr writes "Just hours after Apple released iOS 4.1 to great fanfare, hardware hackers found a way to jailbreak devices that run the new operating system. More surprising still, there doesn't appear to be anything Steve Jobs can do to stop them in the near future. The exploit in the boot ROM of iOS devices was first announced by iPhone Dev-Team member pod2g. It was soon confirmed by other hackers, who said that because the exploit targets such a low-level part of the operating system, Apple won't be able to stop jailbreakers without making significant hardware changes."

An anonymous reader writes "I bought a bunch of old Wing Commander games for Windows, but they use DirectDraw, which Microsoft has deprecated. They don't work too well under Windows 7, so I ended up reimplementing ddraw.dll using OpenGL to output the games' graphics. I wrote an article describing the process and all the fun workarounds I had to come up with, and released all related source code for others to hack on."

CWmike writes "About 40 different Windows applications contain a critical flaw that can be used by attackers to hijack PCs and infect them with malware, says HD Moore, chief security officer at Rapid7 and creator of the open-source Metasploit penetration-testing toolkit. Gregg Keizer reports that the bug was patched by Apple in its iTunes software for Windows four months ago, but remains in more than three dozen other Windows programs. Moore did not reveal the names of the vulnerable applications or their makers, however. Each affected program will have to be patched separately. Moore first hinted at the widespread bug in a message on Twitter on Wednesday. 'The cat is out of the bag, this issue affects about 40 different apps, including the Windows shell,' he tweeted, then linked to an advisory published by Acros, a Slovenian security firm."

superapecommando writes "The richest RIA platforms today (and for the foreseeable future) come from clashing titans Adobe and Microsoft, whose Flash and Silverlight platforms both combine excellent tools for developers and designers, broad client support, strong support for server-side technologies, digital rights management capabilities, and the ability to satisfy use cases as varied as enterprise dashboards, live video streaming, and online games. And each has spawned new updates, to Flash 10.1/AIR 2 and Silverlight 4 respectively, which put them on a near-level playing field. Which one should you choose?"

Crudely_Indecent writes "Not content to own just news stories, Rupert Murdoch is now going after individual words! His BSkyB is fighting a legal battle with Skype, claiming that it owns the 'Sky' in 'Skype.' From the article: 'A spokesman for Sky confirmed that the company has been involved in a "five-year dispute with Skype" over trademark applications filed by the telecomms company. These are, the spokesman added: "including, but not limited to, television-related goods and services."'"

An anonymous reader writes "Apparently the Senate was in such a rush to get out of town that it forgot to name an 'important' bill that it passed, so the bill goes to the House as The ______Act of____. That's how it appears in the Congressional Record, though the Library of Congress has it listed as The XXXXXXAct ofXXXX. As for what's in the bill, well that appears to be as mysterious as the name. It was officially announced as a bill to tax bonuses to execs who received TARP money. But then someone simply deleted the entire bill and replaced it with text about aviation security. And then it was deleted again, and replaced with something having to do with education. However, because of these constant changes, many of the services that track the bill have the old details listed. On top of that, Nancy Pelosi called the House back for an emergency vote on this unnamed bill, and anyone trying to find out what it's about might be misled into thinking its about aviation security or something entirely unrelated to the actual bill. And people wonder why no one trusts Congress." It appears that the government's new martial law plans are being passed after all.
