Comment STEREOSCOPIC (Score 5, Insightful) 261

by Woek (#33915730) Attached to: <em>Hobbit</em> Film Finally Gets Green Light, To Be Shot in 3-D

Using the term 3D for stereoscopic video is probably already so entrenched in the media that it's useless to try and correct them, but it irritates the hell out of me...
There's a huge difference though. A 3D image (the closest we have is a hologram) is one where you can change your viewpoint by moving your head. The perspective changes when you move away or closer. This means that no matter where you are relative to the image, the stereoscopic image that your eyes register is always correct. The fixed images of stereoscopic video don't change, and the perspective is only correct for one position relative to the image. This is what gives people headaches.
I'm holding out for holographic (worthy of the term 3D) displays!

Comment Android makes it (nearly) perfect (Score 1) 544

by Woek (#31981238) Attached to: Review of HTC Desire As Alternative To iPhone
The phone has very good specs. It's fast, the screen is fantastic, and its dimensions are perfect for carrying in you pants' pockets. The only thing I'm disappointed in is the camera, in particular making movies (framerate).
The thing is, Android is what makes it incredible. You get so used to just about everything working perfectly, and to the fact that almost anything is possible, that when something isn't possible, it bugs you a lot!
Have to wait and see how HTC handles software updates...

Lotus Teases With a Fuel-Agnostic Two-Stroke Engine 269

Posted by timothy from the ask-a-lotus-eater dept.
JohnnyBGod writes "Lotus claim to have invented a new, more efficient engine design. The two-stroke, flex-fuel engine can achieve, according to the surprisingly technical press release, 'approximately 10% better [fuel consumption] than current spray-guided direct injection, spark ignition engines.' The engine has a sliding puck arrangement to control its compression ratio, and has direct injection and a wet sump, to eliminate fuel leakage to the exhaust and the need to mix oil with the fuel, two common problems with two-stroke engines. Lotus engineering have released a video explaining the engine's operation."

How Terahertz Waves Tear Apart DNA 279

Posted by kdawson from the tear-a-cell dept.
KentuckyFC writes "Great things are expected of terahertz waves, the radiation in the electromagnetic spectrum between microwaves and the infrared. Terahertz waves pass through non-conducting materials such as clothes, paper, wood and brick and so cameras sensitive to them can peer inside envelopes, into living rooms and 'frisk' people at distance. That's not to mention the great potential they have in medical imaging. Because terahertz photons are not energetic enough to break chemical bonds or ionize electrons, it's easy to dismiss fears over their health effects. And yet the evidence is mixed: some studies have reported significant genetic damage while others, although similar, have reported none. Now a team led by Los Alamos National Labs thinks it knows why. They say that although the forces that terahertz waves exert on double-stranded DNA are tiny, in certain circumstances resonant effects can unzip the DNA strands, tearing them apart. This creates bubbles in the strands that can significantly interfere with processes such as gene expression and DNA replication. With terahertz scanners already appearing in airports and hospitals, the question that now urgently needs answering is what level of exposure is safe."

Games Fail To Portray Gender and Ethnic Diversity 590

Posted by Soulskill from the overrepresented-demon-alien-demographic dept.
eldavojohn writes "A new study has found that game characters tend not to reflect cultural diversity. According to the paper from researchers across four universities (PDF): 'A large-scale content analysis of characters in video games was employed to answer questions about their representations of gender, race and age in comparison to the US population. The sample included 150 games from a year across nine platforms, with the results weighted according to game sales. ... The results show a systematic over-representation of males, white and adults and a systematic under-representation of females, Hispanics, Native Americans, children and the elderly.' The researchers also note that games 'function as crucial gatekeepers for interest in science, technology, engineering and math,' and that without these groups represented properly, 'it may place underrepresented groups behind the curve.'"

Microsoft Warns of New Video ActiveX Vulnerability 146

Posted by Soulskill from the like-one-of-those-pothole-signs dept.
ucanlookitup writes "Microsoft has warned of a 'privately reported' vulnerability affecting IE users on XP or Windows Server 2003. The vulnerability allows remote users to execute arbitrary code with the same privileges as the users. The vulnerability is triggered when users visit a web site with malicious code. 'Security experts say criminals have been attacking the vulnerability for nearly a week. Thousands of sites have been hacked to serve up malicious software that exploits the vulnerability.' The advisory can be found at TechNet. Until Microsoft develops a patch, a workaround is available."

DARPA Wants a 19" Super-Efficient Supercomputer 200

Posted by timothy from the as-do-we-all dept.
coondoggie writes "If you can squish all the processing power of, say, an IBM Roadrunner supercomputer inside a 19-inch box and make it run on about 60 kilowatts of electricity, the government wants to talk to you. The extreme scientists at the Defense Advanced Research Projects Agency this week issued a call for research that might develop a super-small, super-efficient super beast of a computer. Specifically, DARPA's desires for Ubiquitous High Performance Computing (UHPC) will require a new system-wide technology approach including hardware and software co-design to minimize energy dissipation per operation and maximize energy efficiency, with a 50GFLOPS per watt goal."

14-Year-Old Boy Smote By Meteorite Screenshot-sm 435

Posted by samzenpus from the a-grounding-doesn't-seem-that-bad-now dept.
eldavojohn writes "Winning the lottery requires incredible luck and one in a million odds. So does getting hit by a falling space rock. A 14-year-old German boy was granted a three-inch scar by the gods. A pea-sized meteorite smote young Gerrit Blank's hand before leaving a foot-sized crater on the road. The boy's account: 'At first I just saw a large ball of light, and then I suddenly felt a pain in my hand. Then a split second after that there was an enormous bang like a crash of thunder. The noise that came after the flash of light was so loud that my ears were ringing for hours afterwards. When it hit me it knocked me flying and then was still going fast enough to bury itself into the road.' Curiously, the rock was magnetic, and tests were done to verify it is extraterrestrial. The Telegraph notes the only other recorded event of a meteorite striking a person was 'in November 1954 when a grapefruit-sized fragment crashed through the roof of a house, bounced off furniture and landed on a sleeping woman.' Space.com lists a few more anomalies and we discussed the probability of these things downing aircraft recently."
