Embedded Linux Achieves One-Second Boot Time 164

Sam writes "A new goalpost has been set in the race for faster bootup times. MontaVista Software announced (and demonstrated at the Virtual Freescale Technology Forum) a dashboard application going from cold boot to operational in one second flat on their embedded Linux platform. Although this is unlikely to immediately benefit your average Linux user, previous real-time patches have eventually made their way into the main kernel."

Six Men Endure 105-Day Mars Flight Simulator 274

drunken_boxer777 writes with this excerpt from an AP report: "Six men emerged from a metal hatch after 105 days of isolation in a mock spacecraft, still smiling after testing the stresses that space travelers may face on the journey to Mars. They had no television or Internet and their only link to the outside world was communications with the experiment's controllers — who also monitored them via TV cameras — and an internal e-mail system. Communications with the outside world had 20-minute delays to imitate a real space flight."

Swearing Provides Pain Relief, Say Scientists 230

Hugh Pickens writes "Scientific American reports that although cursing is notoriously decried in the public debate, scientists have discovered that swearing may serve an important function in relieving pain. 'Swearing is such a common response to pain that there has to be an underlying reason why we do it,' says Richard Stephens of Keele University in England. A study measured how long college students could keep their hands immersed in cold water. During the chilly exercise, they could repeat an expletive of their choice or chant a neutral word. When swearing, the 67 student volunteers reported less pain and on average endured about 40 seconds longer. How swearing achieves its physical effects is unclear, but the researchers speculate that brain circuitry linked to emotion is involved. Earlier studies have shown that unlike normal language, which relies on the outer few millimeters in the left hemisphere of the brain, expletives hinge on evolutionarily ancient structures buried deep inside the right half like the amygdala, an almond-shaped group of neurons that can trigger a fight-or-flight response in which our heart rate climbs and we become less sensitive to pain."

Eye In the Sky For City Crime Fighting 389

Tiger4 writes "The mayor of the City of Lancaster in the Antelope Valley of southern California is considering a high-definition video flying platform to aid in crime fighting. The aircraft, would circle the city constantly, able to zoom in on activity spots instantly. 'You never know when you are being watched or followed. It would be stupid to commit a crime. You see it with such detail,' said Mayor R. Rex Parris, who took a ride last week in a camera-equipped airplane with pilot Dick Rutan. 'I have every hope that Lancaster will be the first city to deploy it. I've never been so excited about anything.' Dick Rutan is the same pilot who flew around the world non-stop in the Voyager, custom built by his brother Burt Rutan at Scaled Composites in Mojave." The aircraft is nothing special, a garden-variety Cessna or the like, but "the camera is an example of technology developed for and used by the military making a transition to civilian applications, Rutan said."

Is IE Usage Share Collapsing? 575

je ne sais quoi writes "Net Applications normally releases its statistics for browser and operating system usage share on the first of every month. This month, however, the data has not shown up — only a cryptic message stating they are reviewing the data for inexplicable statistical variations and that it will be available soon. Larry Dignan at ZDNet has a blog post that might explain what is happening: Statcounter has released some data that shows a precipitous drop in IE browser use in North America, to the benefit of Firefox, Safari, and Chrome. At the end of May, StatCounter shows IE usage share (for versions 6, 7, and 8 combined) at around 64%; at the beginning of June it is now about 56% — an astounding 8% drop in one month. We should keep in mind the difficulties in estimating browser usage share: this could very well be a change in how browsers report themselves, or some other statistical anomaly. So it will probably be healthy to remain skeptical until trend this is confirmed by other organizations. Have any of you seen drops in IE usage share for Web-sites you administer?"

Passenger Avoids Delay By Fixing Plane Himself 178

It would be a shame if an engineer on a recent Thomas Cook Airlines flight doesn't get a complimentary first class upgrade every time he flies. The engineer was on flight TCX9641 when it was announced that the trip would be delayed eight hours, while a mechanic was flown in to fix a problem. Luckily for the other passengers, the engineer happened to work for Thomsonfly Airlines, which has a reciprocal maintenance agreement with Thomas Cook. After about 35 minutes the man fixed the problem and the flight was on its way. A spokeswoman for Thomas Cook said, "When they announced there was a technical problem he came forward and said who he was. We checked his licence and verified he was who he said he was, and he was able to fix the problem to avoid the delay. We are very grateful that he was on the flight that day."

A Look At Google's Email Spam Prevention 176

CNet has a story about the security measures Google employs to protect their email systems and fight the never-ending war on spam. Their Postini team, acquired two years ago, has a variety of monitoring tools and automated response systems to find and block undesirable messages. Quoting: "The system scores each message on numerous combinations of criteria, assigning a weight to each and then comparing the score to those in a database of several hundred thousand message types that have been flagged as good or bad from Postini honey pots and customer spam reports. ... To block fresh spam attacks not covered by existing heuristic technologies and viruses not covered by existing signature databases Postini relies on proprietary Zero-Hour technology to identify new outbreaks that show up in the traffic patterns and quarantine them for later rescanning. Customers can also create and build out their own white lists of message senders they trust and blacklist others they don't trust. It takes an average of 150 milliseconds for a message to be scanned by the antivirus engines that Postini licenses from McAfee and Authentium.

Cosmic Fireworks Display Seen Inside Helix Nebula 34

goran72 writes "A new image, taken with an infrared camera on the Subaru Telescope in Hawaii, has revealed a cosmic fireworks display, in the form of tens of thousands of previously unseen comet-shaped knots inside the Helix Nebula. Unlike previous optical images of the Helix Nebula knots, the infrared image shows thousands of clearly resolved knots, extending out from the central star at greater distances than previously observed. These images enable astronomers to estimate that there may be as many as 40,000 knots in the entire nebula, each of which are billions of kilometers/miles across. Their total mass may be as much as 30,000 Earths, or one-tenth the mass of our Sun."

200-Year-Old Cipher Finally Cracked 141

Attila Dimedici writes "A code expert just cracked a code used by a friend of Thomas Jefferson in a letter written to Jefferson some 200 years ago. This code is fairly easy to crack using a computer, but extremely difficult without one. I think it would have been much harder if the author had not included an indication as to what code algorithm he used in the letter accompanying the coded message."

HIV/AIDS Vaccine To Begin Phase I Human Trials 329

An anonymous reader writes "An HIV/AIDS vaccine developed in Ontario has applied for Phase 1 human trials. Safety and immunogenicity studies of the vaccine, dubbed SAV001-H, have already been completed on animals. Phase 1 human trials will check the safety of the vaccine on HIV positive volunteers. Phase 2 will then test immunogenicity."

NSA To Build 20-Acre Data Center In Utah 226

Hugh Pickens writes "The Salt Lake City Tribune reports that the National Security Agency will be building a one million square foot data center at Utah's Camp Williams. The NSA's heavily automated computerized operations have for years been based at Fort Meade, Maryland, but the agency began looking to decentralize its efforts following the terrorist attacks of Sept. 11, 2001 and accelerated their search after the Baltimore Sun reported that the NSA — Baltimore Gas & Electric's biggest customer — had maxed out the local grid and could not bring online several supercomputers it needed to expand its operations. The agency got a taste of the potential for trouble January 24, 2000, when an information overload, rather than a power shortage, caused the NSA's first-ever network crash, taking the agency 3 1/2 days to resume operations. The new data center in Utah will require at least 65 megawatts of power — about the same amount used by every home in Salt Lake City — so a separate power substation will have to be built at Camp Williams to sustain that demand. 'They were looking at secure sites, where there could be a natural nexus between organizations and where space was available,' says Col. Scott Olson, the Utah National Guard's legislative liaison. NSA officials, who have a long-standing relationship with Utah based on the state Guard's unique linguist units, approached state officials about finding land in the state on which to build an additional data center. 'The stars just kind of came into alignment. We could provide them everything they need.'"

Bike Projector Makes Lane For Rider 856

hh4m writes "Whether it's San Francisco, New York, or any bicyclistic city in between, you're destined to witness biker after biker dancing with danger, especially at night when visibility is uncomfortably low. Alex Tee and Evan Gant's LightLane device was recently just a concept but is soon to enter reality as a much-needed visual declaration of personal biking space. With a dire shortage of dedicated lanes, LightLane provides urban cyclists with a solution that adapts to them and any route they make take. The compact projector mounts easily to the rear of a bike frame and projects a bike lane-inspired linear pattern that provides great visibility and a familiarity that helps catch a driver's attention."

Staying In Shape vs. a Busy IT Job Schedule? 865

tnok85 writes "I started a new job ~7 months ago at a very large company working a 12-hour night shift (7PM-7AM) in a fairly high volume NOC. Our responsibilities extend during the night to basically cover everything but the most complex situations regarding UNIX/Windows/Linux/App administration, at which point we'll reach out to the on-calls. I live 1.5 hours away as well, so it turns into 4-5 15 hour days a week of sitting still — throw in almost an hour to get ready to leave, and a bit of time after I get home to unwind and I'm out of time to work out. Unfortunately I'm pretty sure I have a very slow metabolism, ever since I was a pre-teen I would gain weight fairly quickly if I didn't actively work out, regardless of how much or what I eat. (Barring starving myself, I suppose...) So, how does somebody who works a minimum of 60 hours over 4 days, often adding another 12 another day, and sometimes working 7-10 days straight like this, stay in shape? I can't hold a workout schedule, (which every person I've talked to in my history says is necessary to stay in shape) and I can't 'wake up early' or 'work out before bed' because I need sleep. Any thoughts/opinions/suggestions?"

Flapping NAV Performs Controlled Hovering Flight 128

An anonymous reader writes "AeroVironment, Inc. was awarded a Phase II contract extension in April from the Defense Advanced Research Projects Agency (DARPA) to design and build a flying prototype for the Nano Air Vehicle (NAV) program. As part of this program AV has accomplished a technical milestone never before achieved: the controlled hovering flight of an air vehicle system with two flapping wings (video) that carries its own energy source and uses only the flapping wings for propulsion and control. Two wings for propulsion and control, nothing else."

The Twitter Book 88

stoolpigeon writes "Microblogging service Twitter has undeniably been a hit, with growth rates that were at times in excess of 1400%. The growth was rapid enough that the site became well known for its periodic, and, at times, extensive downtime. Even with these issues, the service continued to grow rapidly, and with celebrities getting into the mix Twitter was quickly on the radar of mainstream media. The ubiquity of Twitter and ever-increasing coverage of 'tweets' has also brought the inevitable backlash. As with anything that gains high-profile popularity, there are plenty of Twitter haters out there, though the role Twitter has played in the recent Iranian elections seems to have brought more legitimacy to Twitter in the eyes of many. With popularity come books, and quite a few are already out there about and for Twitter, but my favorite so far is The Twitter Book by Tim O'Reilly and Sarah Milstein."
