coondoggie writes "The aspiration that jets may someday fly at over six times the speed of sound took a very real step toward reality recently, as the US Air Force said it successfully married the test aircraft, known as the X-51A WaveRider, to a B-52 in preparation for a Dec. 2 flight test. The X-51A flight tests are intended to demonstrate that the engines can achieve their desired speed without disintegrating. While the X-51 looks like a large rocket now, its applications could change the way aircraft or spaceships are designed, fly into space, support reconnaissance missions and handle long-distance flight operations. At the heart of the test is the aircraft's air-breathing hypersonic scramjet system."

theodp writes "Writing in Washington Monthly, Kevin Carey has seen the future of college education. It costs $99-a-month, and there's no limit on the number of courses you can take. Tiny online education firm StraighterLine is out to challenge the seeming permanency of traditional colleges and universities. How? Like Craigslist, StraighterLine threatens the most profitable piece of its competitors' business: freshman lectures, higher education's equivalent of the classified section. It's no surprise, then, that as StraighterLine tried to buck the system, the system began to push back, challenging deals the company struck with accredited traditional and for-profit institutions to allow StraighterLine courses to be transferred for credit. But even if StraighterLine doesn't succeed in bringing extremely cheap college courses to the masses, it's likely that another player eventually will."

An anonymous reader writes "Nokia is worried that networks may reject selling the N900 because it won't allow them to mess with the operating system. Nokia has previously showed the N900 running a root shell and it appears to use the same interface for IM and phone functions. Meanwhile, Verizon is claiming that 'exclusivity arrangements promote competition and innovation.' Is it too late to explain to people why $99+$60/month is not better than $600+$20/month?"

juct writes "Beginning with versions 3.5.3 and 3.0.14 of Firefox, Mozilla is going to check the version of installed Adobe Flash plug-ins and warn users if it discovers an outdated version with potential security holes. Mozilla confirmed this new security feature and said that the Flash version check was part of a wider commitment to 'protect users from emerging threats online.' Just recently, a study confirmed that 80 per cent of users surf with a vulnerable version of Adobe's plug-in."

lousyd writes "Andy Grove, former CEO of Intel and current instructor at Stanford Business School, has a message for industry. He believes that health care and energy, especially, could learn a lesson from computing's innovative and relatively government-free history. He asks students to imagine if mainframe vendors had asked government to prop them up in the same way that General Motors recently was. On the issue of computer patents, he insists that firms must use their patents or lose them: 'You can't just sit on your a** and give everyone the finger.'"

An anonymous reader sends along this update to the ongoing patent battle between Microsoft and i4i involving XML formatting in Word. "Microsoft's motion to stay an injunction has been granted; the US Court of Appeals for the Federal Circuit has allowed the company to keep selling Word as it appeals a patent ruling from last month. The injunction had an effective date of October 10, but the motion to stay blocks the injunction until the appeal process is complete. If upheld, the injunction wouldn't stop existing users from using Word, but it could prevent the software giant from selling Word 2003 or Word 2007, the most common versions of Word currently on the market, and would require the company to significantly tweak Word 2010, which is slated for the first half of next year. The victory is a small one for Microsoft; the company still has the whole appeals process to go through. 'We are happy with the result and look forward to presenting our arguments on the main issues on September 23,' a Microsoft spokesperson told Ars. 'Microsoft's scare tactics about the consequences of the injunction cannot shield it from the imminent review of the case by the Federal Circuit Court of Appeal on the September 23 appeal,' said i4i chairman Loudon Owen in response to the court's decision."

An opinion piece on Gamasutra looks into the common perception that a first-person view provides a much more immersive experience in shooters. The author argues that this concept needs to be reconsidered, as immersion nowadays is more dependent on what you see, rather than how you see it. The question is further complicated by ever-improving technology and new control schemes. "It's important to realize that making a first-person game almost necessarily means making a game for the dedicated gamer. Innovations on the interface side could help lower the casual block, perhaps through the Wii, Project Natal, or the PS3's new motion controller. Regardless, it will take a lot of work and concerted effort to penetrate the casual audience with a first-person camera. The question is whether we even need to, when there are so many camera systems that games have yet to fully explore."

Lord Northern writes "According to several news sources, NASA's Kepler mission is said to be able to detect habitable moons orbiting planets in other star systems. Kepler is a space telescope designed to detect exoplanets. Its mission will have it orbiting the Sun for 3.5 years, after which we'll be able to tell if any of our neighboring stars actually have planetary systems around them. However, apparently we will be able to detect not only exoplanets, but also exomoons orbiting those exoplanets. The Kepler team came to that conclusion after running a computer simulation which found that the telescope was sensitive enough to detect the gravitational pull of an orbiting moon (PDF). This means that the data expected by the end of the mission is going to be very rich, and it is said that moons as small as 0.2 times the mass of earth could be detected. Further details about the Kepler mission are available from NASA."

Back in July, Amazon faced public outrage over their decision to delete ebook copies of 1984 and Animal Farm from the Kindles of customers who purchased them. Shortly thereafter, CEO Jeff Bezos offered an apology, acknowledging that Amazon handled the situation in a "stupid" and "thoughtless" manner. Now, they're offering something more substantial: anyone who had an ebook deleted can now have it restored, apparently with annotations intact. Any customer who isn't interested in a new copy can get either an Amazon gift certificate or a check for $30.

An anonymous reader brings word of a new application for PageRank, Google's link analysis algorithm: monitoring the food web in an ecosystem. A team of researchers found that a modified version of PageRank can predict with great accuracy which species are vital to the existence of others. Quoting: "Every species is embedded in a complex network of relationships with others. A single extinction can cascade into the loss of seemingly unrelated species. Investigating when this might happen using more conventional methods is complicated, as even in simple ecosystems, the number of combinations exceeds the number of atoms in the universe. So, it would be impossible to try them all. Co-author Dr. Stefano Allesina realized he could apply PageRank to the problem when he stumbled across an article in a journal of applied mathematics describing the Google algorithm. 'First of all, we had to reverse the definition of the algorithm. In PageRank, a web page is important if important pages point to it. In our approach, a species is important if it points to important species.'"

Urchin writes "Shor's quantum algorithm, which offers a way to crack the commonly-used RSA encryption algorithm, has been demonstrated on a silicon chip for the first time. The algorithm was first demonstrated on large tabletop arrays 3 years ago, but the photonic quantum circuit can now be printed relatively easily onto a silicon chip just 26 mm long. You can see the abstract from the team's academic paper in the journal Science; the full text requires a subscription."

Barence writes "The British government's official figures on the level of illegal file sharing in the UK come from questionable research commissioned by the music industry. The Radio 4 show named More or Less examined the government's claim that 7m people in Britain are engaged in illegal file sharing. The 7m figure actually came from a report written about music industry losses for Forrester subsidiary Jupiter Research. The report was privately commissioned by none other than the UK's music trade body, the BPI. The 7m figure had been rounded up from an actual figure of 6.7m, gleaned from a 2008 survey of 1,176 net-connected households, 11.6% of which admitted to having used file-sharing software — in other words, only 136 people. That 11.6% was adjusted upwards to 16.3% 'to reflect the assumption that fewer people admit to file sharing than actually do it.' The 6.7m figure was then calculated based on an estimated number of internet users that disagreed with the government's own estimate. The wholly unsubstantiated 7m figure was then released as an official statistic."

jellomizer writes 'I am a manager of a small Software Development department, looking to hire some more developers. By edict of the CEO, the search must be made globally, so we are dealing with different cultures and different ideas of truth and embellishment, etc. To try to counteract this, we give the potential employees tests where I watch what they do, to see if they actually know what they say they know. However, it seems a lot of applicants drop out when I mention that this test is mandatory. Is this a sign that we caught them in a lie, or are we weeding out good people where we shouldn't be? Would you be willing to take a test as part of an interview? If so, is there any type of heads up you would like to know beforehand to make the decision of whether to take the test easier?' What other difficulties have people seen while trying to hire from many different cultures?

An anonymous reader writes to mention that Cushing Academy has decided to leap into the future by getting rid of all the books in their library and going completely digital. Instead of dusty stacks, the library is spending close to half a million dollars to install all the hallmarks of a digital learning center. Flat screen TVs, "laptop friendly carrels," and a coffee shop are just the first step in building an area that allows students access to millions of books as opposed to several thousand. Of course, not everyone is completely sold on this move: "[Keith Michael Fiels, executive director of the American Library Association] said the move raises at least two concerns: Many of the books on electronic readers and the Internet aren't free and it may become more difficult for students to happen on books with the serendipity made possible by physical browsing. There's also the question of the durability of electronic readers. 'Unless every student has a Kindle and an unlimited budget, I don't see how that need is going to be met,' Fiels said. 'Books are not a waste of space, and they won't be until a digital book can tolerate as much sand, survive a coffee spill, and have unlimited power. When that happens, there will be next to no difference between that and a book.'"
