Inside the Lab of One of the World's Last Holographers 86

Posted by samzenpus from the old-school-effects dept.
MMBK writes "In the heyday of holography, back in the 1970s, there were four schools dedicated to the holographic arts around the world, and five studios in New York City alone. Today, there are only a few left in the world. And no one is holding the candle higher than Doctor Laser."

Is a US High-Speed Railway Economically Feasible? 1139

Posted by samzenpus from the price-of-admission dept.
An anonymous reader writes "The federal government has committed at least $8-billion (and counting) for the development of a nationwide high-speed intercity passenger railway system in almost three-dozen states. Rail advocates have long dreamed of an extensive railway grid that will provide clean, speedy, energy-efficient travel. The high-speed rail program is also expected to create thousands of desperately needed jobs, while reducing the nation's dependence on foreign oil and easing gridlocked highways and congested air-space. However, this noble, ambitious, multi-year plan faces a multitude of obstacles — including costs that will no doubt escalate as the years pass by; and an American public that may be reluctant to relinquish the independence and convenience of their beloved automobiles for a train."

Zombie Ants and Killer Fungus 125

nibbles2004 writes "An article in the Guardian newspaper shows how parasitic fungi evolved the ability to control ants they infect, ultimately leading the ant to its death. The fungus controls the ant's movements to a suitable leaf and causes the ant to grip onto the leaf's central stem, allowing the fungus to spore, which will allow more ants to become infected."

Owning Virtual Worlds For Fun and Profit 82

Posted by samzenpus from the cash-for-gold dept.
Trailrunner7 writes "Threatpost has a guest column by security researcher Charlie Miller on the ways in which attackers can easily take advantage of vulnerabilities in virtual worlds and perhaps online games to get control of other players' characters and avatars and even cash out their real-world bank accounts. From the article: 'It turns out that Second Life uses QuickTime Player to process its multimedia. When I started looking into virtual world exploits, with the help of Dino Dai Zovi, there was a stack buffer overflow in QuickTime Player that had been discovered by Krystian Kloskowski but had not yet been patched. In Second Life it is possible to embed images and video onto objects. We embedded a vulnerable file onto a small pink cube and placed it onto a [tract] of land we owned. No matter where the cube was, if a victim walked onto the land and had multimedia enabled (recommended but not required), they would be exploited. The cube could be inside a building, hovering in the air, or even under the ground, and the result was the same.'"

spopepro writes "While un-captioned cats might be of limited interest to the /. community, I found this column on how a fabricated statistic takes on a life of its own interesting. Starting with the Humane Society of the United States' (HSUS) claim that the unsterilized offspring of a cat will '...result in 420,000 cats in 5 years,' the author looks at other erroneous numbers, where they came from and why they won't go away."

Supercomputing, There's an App For That 66

Posted by samzenpus from the in-the-palm-over-your-hand dept.
aarondubrow writes "Researchers at MIT have created an experimental system for smart phones that allows engineers to leverage the power of supercomputers for instant computation and analysis. The team performed a series of expensive high-fidelity simulations on the Ranger supercomputer to generate a small "reduced model" which was transferred to a Google Android smart phone. They were then able to solve engineering and fluid flow problems on the phone and visualize the results interactively. The project proved the potential for reduced order methods to perform real-time and reliable simulations for complicated problems on handheld devices."

1978 Cryptosystem Resists Quantum Attack 185

Posted by samzenpus from the built-to-last dept.
KentuckyFC writes "In 1978, the CalTech mathematician Robert McEliece developed a cryptosystem based on the (then) new idea of using asymmetric mathematical functions to create different keys for encrypting and decrypting information. The security of these systems relies on mathematical steps that are easy to make in one direction but hard to do in the other. Today, popular encryption systems such as the RSA algorithm use exactly this idea. But in 1994, the mathematician Peter Shor dreamt up a quantum algorithm that could factorise much faster than any classical counterpart and so can break these codes. As soon as the first decent-sized quantum computer is switched on, these codes will become breakable. Since then, cryptographers have been hunting for encryption systems that will be safe in the post quantum world. Now a group of mathematicians have shown that the McEliece encryption system is safe against attack by Shor's algorithm and all other known quantum algorithms. That's because it does not depend on factorisation but gets its security from another asymmetric conundrum known as the hidden subgroup problem which they show is immune to all known quantum attacks."

Toshiba Claims Bit-Patterned Drive Breakthrough 151

Posted by samzenpus from the packing-in-the-bits dept.
CWmike writes "Toshiba will detail a breakthrough in data storage later Wednesday that it says paves the way for hard drives with vastly higher capacity than today, reports Martyn WIlliams. The breakthrough has been made in the research of bit-patterned media, a magnetic storage technology that is being developed for future hard disk drives. Bit-patterned media breaks up the recording surface into numerous magnetic bits, each consisting of a few magnetic grains. Under a microscope, the magnetic bits look like thousands of tiny spheres crammed next to each another. Data is stored on these magnetic bits: One magnetic bit can hold one bit of data. Prototypes of the media have been made before but Toshiba says its engineers have, for the first time, succeeded in producing a media sample in which the magnetic bits are organized into a pattern of rows."

Google's CEO Warns Kids Will Have to Change Names to Escape "Cyber Past" 706

Posted by samzenpus from the watch-how-you-play dept.
Google's Eric Schmidt says that people's private lives are so well documented now that the young will have to change their names when reaching adulthood to avoid their youthful indiscretions. In an interview with the Wall Street Journal Schmidt says: "I don't believe society understands what happens when everything is available, knowable and recorded by everyone all the time." A fresh start from the stupid things you did as a kid seems like a good thing. Now we just need a way to get rid of the dreaded family photo album.

DocBook 5 68

Posted by samzenpus from the read-all-about-it dept.
frisket writes "Definitive guides by the authors or maintainers of software systems tend to have the edge over other documentation because of the insight they provide. DocBook 5 — The Definitive Guide comes well up to scratch. DocBook has long been the de facto standard for computer system documentation in XML (and SGML before that), and Norm Walsh has revised and updated both the language and the documentation in a concise and valuable form, usable both by beginners and by tech doc experts." Read on for the rest of frisket's review.

Why You Shouldn't Worry About IPv6 Just Yet 425

Posted by CmdrTaco from the more-worried-about-a-sandwich dept.
nk497 writes "While it's definitely time to start thinking about IPv6, it's not time for most to move up to it, argues Steve Cassidy, saying most can turn it off in Windows 7 without causing any trouble. Many network experts argue we're nearing network armageddon, but they've been saying that for years.'This all started when Tony Blair was elected. The first time. Yep, that's how long IPv6 has been around, and it's quite a few weeks ago now.' He says smart engineering has avoided many of the problems. 'Is there an IPv6 "killer app" yet for smaller networks? No. Is there any reason based on security or ease of management — unless you're running a 100,000-seat network or a national-level ISP — for you to move up to it? No. Should you start to do a bit of reading about it? That's about the stage we're truly at, and the answer to that one is: yes,' he says."

Linux X.org Critical Security Flaw Silently Patched 259

Posted by CmdrTaco from the pay-no-attention dept.
eldavojohn writes "On June 17th, the X.org team was notified by Invisible Things Lab of a critical security flaw (PDF) that affected both x86_32 and x86_64 platforms. The flaw deals with escalated privileges of a user process that has access to the X server. The founder of ITL said of the flaw, 'The attack allows a (unpriviliged) user process that has access to the X server (so, any GUI application) to unconditionally escalate to root (but again, it doesn't take advantage of any bug in the X server!). In other words: any GUI application (think e.g. sandboxed PDF viewer), if compromised (e.g. via malicious PDF document) can bypass all the Linux fancy security mechanisms, and escalate to root, and compromise the whole system.' This has apparently been a security flaw since kernel 2.6 was released. From the article, 'On 13 August, Linus Torvalds committed an initial fix, but several patches were added afterward for various reasons. The problem has been addressed in versions 2.6.27.52, 2.6.32.19, 2.6.34.4 and 2.6.35.2 of the kernel.'"

Did Sea Life Arise Twice? 238

Posted by CmdrTaco from the shoulda-got-it-right-the-first-time dept.
eldavojohn writes "Dr. Adam Maloof has found fossils of sea sponges in Australia from 650 million years ago. You might think this is no big deal unless you consider that sea sponges were thought to have arisen 520 million years ago. These fossils predate the oldest hard bodied fossils we have by a hundred million years. Dr. Maloof is now wondering if life might have arisen twice after the first attempt was quashed 635 million years ago: 'Since animals probably did not evolve twice, we are suddenly confronted with the question of how some relative of these reef-dwelling animals survived the Snowball Earth.' So how is it that life survived the Marinoan glaciation? The BBC has a video on the topic and Wikipedia has a time line of the Proterozoic Eon into the Paleozoic Era."

Russian Scholar Warns Of US Climate Change Weapon Screenshot-sm 415

Posted by samzenpus from the hurricane-cannon dept.
According to Russian political scientist, and conspiracy aficionado Andrei Areshev the high heat, and poor crop yields of Russia, and other Central Asian countries may be the result of a climate weapon created by the US military. From the article: "... Areshev voiced suspicions about the High-Frequency Active Aural Research Program (HAARP), funded by the US Defense Department and the University of Alaska. HAARP, which has long been the target of conspiracy theorists, analyzes the ionosphere and seeks to develop technologies to improve radio communications, surveillance, and missile detection. Areshev writes, however, that its true aim is to create new weapons of mass destruction 'in order to destabilize environmental and agricultural systems in local countries.'"
