Comments: 28 +-   UAVs Go Green With Fuel-Cell Powered "Ion Tiger" on Sunday November 22, @01:23AM

Hugh Pickens writes "Increasingly, the military is deploying unmanned aerial vehicles, or UAVs, as eyes in the sky to scan the ground for targets and threats, especially for missions that are too dangerous for manned aircraft. Now Live Science reports that a new robotic spy plane called 'Ion Tiger' will harness alternative energy to make it more covert and longer lasting than battery-powered or engine powered UAVs. A 550-watt, 0.75 horsepower hydrogen fuel cell will power the Ion Tiger with four times the efficiency of a comparable internal combustion engine and seven times the energy of the equivalent weight of batteries. When Ion Tiger took flight on October, it exceeded any demonstration of electrically powered flight so far, flying 23 hours and 17 minutes. 'And it carried a 5 lbs. payload to boot — enough to carry, say, a day-and-night camera,' says researcher Karen Swider-Lyons, head of the alternative energy section at the Naval Research Laboratory in Washington. 'No one has come close to flying 24 hours with a significant payload before.' Another big advantage is the Ion Tiger's reduced noise, heat and emissions. 'Think about lawnmowers or chainsaws — they're really loud,' says Swider-Lyons. 'It's hard to spy on people when they know you're there, so you had to fly them at high altitudes to keep them from being heard.'"

Comments: 437 +-   Ten Things Mobile Phones Will Make Obsolete on Saturday November 21, @07:02PM

An anonymous reader writes "recombu.com has an article examining ten things mobile phones will make obsolete, including phone booths, wristwatches and handheld games consoles. It's interesting to see how many devices have been absorbed into mobile phone technology and it begs the question, are we better off having everything in one device? The author poignantly concludes that while it's great to have so much power at our fingertips it does mean that some of us will rely on mobile phones for even basic mental tasks, which is great until the battery runs out."

Comments: 143 +-   Best Practices For Infrastructure Upgrade? on Saturday November 21, @05:50PM

from the thinking-ahead dept.
networking
An anonymous reader writes "I was put in charge of an aging IT infrastructure that needs a serious overhaul. Current services include the usual suspects, i.e. www, ftp, email, dns, firewall, dhcp — and some more. In most cases, each service runs on its own hardware, some of them for the last seven years straight. The machines still can (mostly) handle the load that ~150 people in multiple offices put on them, but there's hardly any fallback if any of the services dies or an office is disconnected. Now, as the hardware must be replaced, I'd like to buff things up a bit: distributed instances of services (at least one instance per office) and a fallback/load-balancing scheme (either to an instance in another office or a duplicated one within the same). Services running on virtualized servers hosted by a single reasonably sized machine per office (plus one for testing and a spare) seem to recommend themselves. What's you experience with virtualization of services and implementing fallback/load-balancing schemes? What's Best Practice for an update like this? I'm interested in your success stories, anecdotes but also pointers and (book) references. Thanks!"

Comments: 228 +-   Microsoft, Other Rivals Slam Google Chrome OS on Saturday November 21, @04:43PM

os
CWmike writes "Microsoft is, predictably, not all that impressed by Google Inc.'s demonstration of its upcoming Chrome OS, saying 'From what was shared, it appears to be in the early stages of development,' a Microsoft spokeswoman said. 'From our perspective, however, our customers are already voicing their approval of the way Windows 7 just works — across the Web and on the desktop, and on all sizes and types of PCs — purchasing twice as many units of Windows 7 as we've sold of any other operating system over a comparable time.' But neither were potential rivals who make Linux and instant-on operating systems. Chrome OS claimed 7-second boot times, and and ability to run Web apps within another 3 seconds failed to impress Woody Hobbs, president and CEO of Phoenix Technologies, a long-time BIOS software maker that has re-invented itself with a Linux-based instant-on OS called HyperSpace. 'Instant-on is about being able to access your Internet applications in one second. Seven seconds is too long,' Hobbs said. 'There is no such thing as "cold boot" for today's mobile PCs such as netbooks and smartbooks. You should be able to use your netbook like you use your smartphone — a press of a button and you are "on."' Mark Lee, CEO of DeviceVM Inc., said Google's favoritism towards its own browser and Web apps could rub some users the wrong way, especially those outside of the US. 'In China, users prefer Baidu, not Google,' Lee said. DeviceVM's Splashtop platform boots into Firefox within seconds and uses Yahoo or Baidu as default search engines instead of Google."

security
An anonymous reader writes "After the ikee worm that displayed a picture of Rick Astley on jailbroken iPhones, the first malicious iPhone worm (Google translation; original, in Dutch) has now been discovered in the wild. Internet provider XS4ALL in the Netherlands encountered several of such devices (link in Dutch) on the wireless networks of their customers and put out a warning. After obtaining a copy of the malware it was discovered that the jailbroken phones, which are exploited through openSSH with a default password, scan IP ranges of mobile internet providers for other vulnerable iPhones, phone home to a C&C botnet server, are able to update themselves with additional malware and have the ability to dump the SMS database as well. Owners of a jailbroken iPhone with a default root password are advised to flash to the latest Apple firmware in order to ensure no malware is present."

transportation
cheeks5965 writes "We've argued before over compressed air vehicles, a.k.a. air cars. Air cars are an enchanting idea, providing mobility with zero fuel consumption or environmental impacts. The NYTimes' Green Inc. blog reports that the reality is less rosy. New research from UC Berkeley and ICF International puts a period at the end of the discussion, showing that compressed air is a very poor fuel, storing less than 1% of the energy in gasoline; air cars won't get you far, with a range of just 29 miles in typical city driving; and despite appearing green the vehicles are worse for the environment, with twice the carbon footprint as gasoline vehicles, from producing the electricity used to compress the air. Given these barriers, manufacturer claims should definitely be taken with a grain of salt."

scifi
Barence writes "Science fiction has long inspired real-world technology, but are the authors of sci-fi stories finally running out of steam? PC Pro has traced the history of sci-fi's influence on real-world technology, from Jules Verne to Snow Crash, but suggests that writers have run out of ideas when it comes to inspiring tomorrow's products. 'Since Snow Crash, no novel has had quite the same impact on the computing world, and you might argue that sci-fi and hi-tech are drifting further apart,' PC Pro claims. Author Charles Stross tells the magazine that he began writing a sci-fi novel in 2005 and 'made some predictions, thinking that in ten years they'd either be laughable or they'd have come true. The weird bit? Most of them came true already, by 2009.'"

eldavojohn writes "One of the driving forces behind the ESRB toughening its ratings is closing its doors on December 31st, 2009. The National Institute on Media and the Family was funded by Fairview Health Services, and simply could no longer justify the yearly $750,000 price tag given today's economic climate. NIMF's reign of nagging has been pretty consistent since 1996, and was often indirectly featured on Slashdot. Don't worry, president and founder Dr. David Walsh promises to keep writing and giving speeches ... and imploring us all to think of the children."

Comments: 131 +-   WHO Says Swine Flu May Have Peaked In the US on Saturday November 21, @11:18AM

medicine
Hugh Pickens writes "The World Health Organization says that there were 'early signs of a peak' in swine flu activity in parts of the Northern Hemisphere, including the US. The American College Health Association, which surveys more than 250 colleges with more than three million students, said new flu cases had dropped 27 percent in the week ending on November 13th from the week before, the first drop since school resumed in the fall. Nonetheless, Dr. Anne Schuchat, the director of vaccination and respiratory disease at the CDC, chose her words carefully. 'We are in better shape today than we were a couple of weeks ago,' she says. 'I wish I knew if we had hit the peak. Even if a peak has occurred, half the people who are going to get sick haven't gotten sick yet.' Privately, federal health officials say they fear that if they concede the flu has peaked, Americans will become complacent and lose interest in getting vaccinated, increasing the chances of another wave. However, Dr. Lone Simonsen, a former CDC epidemiologist, says she expects a third wave in December or January, possibly beginning in the South again. Based on death rates in New York City and in Scandinavia, Simonsen argues that both 1918 and 1957 had mild spring waves followed by two stronger waves, one in fall and one in midwinter, adding that in the pandemic of 1889, the bulk of the deaths occurred in the third wave. 'If people think it's going away, they can think again.'"
