NASA Tests Flying Airbag 118

coondoggie writes "NASA is looking to reduce the deadly impact of helicopter crashes on their pilots and passengers with what the agency calls a high-tech honeycomb airbag known as a deployable energy absorber. So in order to test out its technology NASA dropped a small helicopter from a height of 35 feet to see whether its deployable energy absorber, made up of an expandable honeycomb cushion, could handle the stress. The test crash hit the ground at about 54MPH at a 33 degree angle, what NASA called a relatively severe helicopter crash."

Linux Reaches 32% Netbook Market Share 389

christian.einfeldt writes "Linux netbooks have captured 32% of the global netbook market, says Jeff Orr, an analyst with consumer computer research firm ABI Research. The largest share of netbook sales is in the Asia-Pacific region, including Japan, Australia, and New Zealand, according to Orr. ABI's latest figures align with a statement by Dell executives in February of this year, to the effect that Linux netbooks comprised about 33% of Dell shipments of Dell Inspiron mini 9s netbooks. These data points cast doubt on claims by Microsoft that Windows XP has captured 98% of the netbook market (a figure Microsoft later revised to 93%). In an interview with DesktopLinux.com, Orr made clear that the 32% Linux netbook market share did not include either user-installed Linux or dual-boot systems, but was confined to just pre-installed Linux shipments."

Submission + - Google Launches Public DNS Resolver (blogspot.com)

AdmiralXyz writes: Google has announced the launch of their free DNS resolution service, called Google Public DNS. According to their blog post, Google Public DNS uses continuous record prefetching to avoid cache misses- hopefully making the service faster- and implements a variety of techniques to block spoofing attempts. They also say that (unlike an increasing number of ISPs), Google Public DNS behaves exactly according to the DNS standard, and will not redirect you to advertising in the event of a failed lookup. Very cool, but of course there are questions about Google's true motivations behind knowing every site you visit...

Google Apps Not the DC Success Many Believe? 139

theodp writes "Google touts its partnership with the District of Columbia government, presenting it as quite the Google Apps success story. So as part of his coverage of last week's Gmail outage, nextgov's Gautham Nagesh called the DC government, but was told they hadn't heard of any reports of outages among city employees. Nagesh wrote this off to safeguards put in place for the government by Google, but readers tipped him off to another explanation: 'Despite all the press releases trumpeting Google in DC,' an anonymous commenter wrote, 'Exchange is still the city's primary email system.' Nagesh followed up, and was surprised to learn that there is indeed no Gmail in DC government. This all seemed rather strange to Nagesh, considering how much attention former DC CTO and current Federal CIO Vivek Kundra has received for implementing Google Apps for District employees. Reporting separately, CNET's Elinor Mills was told by a DC spokeswoman that while Google Apps is available to 38,000 DC city employees, only 4,000 are actively using it. The spokeswoman added that Gmail could potentially replace Microsoft Exchange, 'but this decision has not been made yet.'"

Chrome 4.0 Vs. Opera 10 Vs. Firefox 3.5 354

Jim Karter writes "In a three-way cage match, LifeHacker threw Chrome 4, Firefox 3.5, and Opera 10 into the ring and let the three browsers duke it out to see which would emerge as the fastest app for surfing the web. Quoting: 'Like all our previous speed tests, this one is unscientific, but thorough. We install the most current versions of each browser being tested — in this case, Opera 10, Chrome's development channel 4.0 version, and the final Firefox 3.5 with security fixes — in a system with a 2.0 GHz Intel Centrino Duo processor and 2GB of RAM, running Windows XP.'"

Submission + - Why Is Linux Notebook Battery Life Still Poor?

Ganty writes: "I recently purchased a Lenovo W500 notebook and after 'downgrading' to XP and creating a dual partition I found that I had a battery life of nearly three hours using the long life battery, at this point I was a happy camper because it means that I can watch a DVD during a flight. I then tried various Linux distributions and found the battery life under FOS to be VERY disappointing with an average of 45 minutes before a warning message. After settling on Ubuntu I then spent three days trying various hardware tweaks but I only managed to increase the battery life to one and a half hours.

Unwanted services have been disabled, laptop mode has been enabled, the dual core CPU reduces speed when idle and the hard drive spins down when not needed.

Obviously Apple with their X86 hardware and BSD based OS have got it right because the Macbooks last for hours, and a stock install of MS Windows XP gives me three hours of life. Why is battery life on notebooks so poor when using Linux? Some have suggested disabling various hardware items such as bluetooth and running the screen at half brightness but XP doesn't require me to do this and still gives a reasonable battery life.

What have I missed?

ASCII Portal In the Works 82

Rock, Paper, Shotgun points out a video showing Portal, redone with ASCII graphics. It's still in development, but appears to be quite far along. Its creator, Cymon, says on his website, "I have Windows XP, so all binaries will by default be for Windows. But I will also be including the source code with the distribution and am doing my best to write it cross-platform compatible, so it should compile in Linux and Mac. I've had successful builds done in Linux." He also talks in detail about his design plans and ideas.

Artist Wins £20,000 Grant To Study Women's Butts 202

Sue Williams has been awarded a £20,000 grant by the Arts Council of Wales, to "explore cultural attitudes towards female buttocks." Sue plans to examine racial attitudes towards bottoms in Europe and Africa and create plaster casts of women's behinds to try to understand their place in contemporary culture. And here I've been studying the issue all these years for free like a sucker!

Khronos Launches Initiative For Standards-Based 3-D Web Content 117

xororand writes "The initiative called 'Accelerated 3D on the web' has been formed by the Khronos consortium with the goal to define an open standard for 3D content on the web, using OpenGL and ECMAscript, as it was suggested by Mozilla developers. 'The Khronos(TM) Group today announced an initiative to create an open, royalty-free standard for bringing accelerated 3D graphics to the Web. In response to a proposal from Mozilla, Khronos has created an "Accelerated 3D on Web" working group that Mozilla has offered to chair. This royalty-free standard will be developed under the proven Khronos development process with a target of a first public release within 12 months.' Unlike previous attempts to establish 3D standards for the web, this one might be actually successful due to the use of existing open standards, and the increasing performance of ECMAscript engines."

Mobile Gaming and the War On Fat Fingers 28

Gamasutra reports on a talk at this year's Game Developers Conference by Mike Pagano, game producer for EA Mobile. Pagano brought up the difficulty in designing games for devices like the iPhone, where screen real estate is already limited, and a poorly implemented UI will result in players' thumbs and fingers blocking crucial parts of the action. Quoting: "Pagano recommends button maps on the bottom of the screen, finger-sized, whenever possible, keeping interface away from the play area. 'Apple puts the main interactions on the very bottom of the screen,' he said. 'When you're unlocking for example, you know you can read what's on top. That's a huge thing, especially when you're designing games.' ... For accelerometer input, 'we did a lot of tuning with this SOB,' Pagano said, referring to Spore Origins. Pagano stressed that games using the accelerometer should have a mechanism to allow players to change their zero positions, effectively letting them play in a variety of positions — sitting in bed, leaning over the device, or holding it up. Early in development, Spore Origins had a touchscreen control scheme. 'Where it started to fall down was, again, sausage fingers.' Said Pagano. 'We made our decision right there to flip to the accelerometer.'"

NASA Tests Heaviest Chute Drop Ever 226

Iddo Genuth writes "NASA and the US Air Force have successfully tested a new super-chute system aimed at reclaiming reusable Ares booster rockets. On February 28, 2009 a 50,000-pound dummy rocket booster was dropped in the Arizona desert and slowed by a system of five parachutes before it crashed to the ground. The booster landed softly without any damage. This was possibly the heaviest parachute drop ever, and NASA is planning to perform even heavier drops of up to 90,000 pounds in the next few months."

Max Payne 3 Announced For Next Winter 73

tordavis writes with news that Rockstar Games has announced Max Payne 3 is in the works for the PS3, Xbox 360, and PC. It's currently planned for this coming winter. Quoting the news release: "'We're starting a new chapter of Max's life with this game,' said Sam Houser, Founder of Rockstar Games. 'This is Max as we've never seen him before, a few years older, more world-weary and cynical than ever. We experience the downward spiral of his life after the events of Max Payne 2 and witness his last chance for salvation.' Since leaving the NYPD and New York itself behind, Max has drifted from bad to worse. Double-crossed and a long way from home, Max is now trapped in a city full of violence and bloodshed, using his weapons and instincts in a desperate search for the truth and a way out."
