OpenGL Shading Language 3rd Edition Screenshot-sm 46

Posted by samzenpus from the read-all-about-it dept.
Martin Ecker writes "The “OpenGL Shading Language” (also called the Orange Book because of its orange cover) is back in its third edition, with updated discussions of the OpenGL shading language (up to version 1.40, introduced with OpenGL 3.1). Like the previous edition, the third edition of the book is one of the best introductions to GLSL — the OpenGL Shading Language — that not only teaches the ins and outs of GLSL itself but also explains in-depth how to develop shaders in GLSL for lighting, shadows, animation, and other topics relevant to real-time computer graphics." Keep reading for the rest of Martin's review.

NASA, European Space Agency Want To Go To Mars 129

Posted by Soulskill from the merging-to-beat-their-competitors dept.
coondoggie writes "NASA and the European Space Agency (ESA) are aiming to cooperate on all manner of robotic orbiters, landers and exploration devices for a future trip to Mars. Specifically, NASA and ESA recently agreed to consider the establishment of a new joint initiative to define and implement their scientific, programmatic, and technological goals for the exploration of Mars. The program would focus on several launch opportunities with landers and orbiters conducting astrobiological, geological, geophysical, climatological, and other high-priority investigations and aiming at returning samples from Mars in the mid-2020s."

Comment High degree of false positives (Score 1) 652

Since you can pretty much hit a landmine by walking into a random patch of Iraqi desert and throwing a rock, I don't find it surprising that any land mine sensing divining rod would have at least some random chance of success. I think that past research has shown that any tool that is picking arbitrary points on a grid will find positive results for "hidden" items (explosive or not) with a frequency of occurrence that matches the normal distribution. I encourage you to read The Drunkard's Walk by Leonard Mlodinow for a better description than I can give.

Giant Rift In Africa Will Create a New Ocean 168

Posted by kdawson from the basin-and-range dept.
Hugh Pickens writes "Researchers at the University of Rochester believe that a 35-mile rift in the desert of Ethiopia will likely become a new ocean in a million years or so, connecting the Red Sea with the Gulf of Aden. Using newly gathered seismic data, researchers have reconstructed how the rift tore open along its entire 35-mile length in just days. Dabbahu, a volcano at the northern end of the rift, erupted first, then magma pushed up through the middle of the rift area and began 'unzipping' the rift in both directions. 'We know that seafloor ridges are created by a similar intrusion of magma into a rift, but we never knew that a huge length of the ridge could break open at once like this,' says Cindy Ebinger, professor of earth and environmental sciences at the University of Rochester. The results show that highly active volcanic boundaries along the edges of tectonic ocean plates may suddenly break apart in large sections, instead of in bits, as the leading theory had previously held. The sudden large-scale events pose a much more serious hazard to populations living near the rift than would several smaller events."

Comment Zanac anyone? (Score 2, Informative) 404

by meadowsoft (#29732473) Attached to: Should Computer Games Adapt To the Way You Play?
I seem to remember in the promotional materials for the NES game Zanac (by FCI) that the game was supposed to get dynamically harder the better you played. When I was playing, I specifically remember this being the case, and that I enjoyed the game more as a result. I used to be able to play straight through to the 10th (out of 13) levels without dying once, and then I would die multiple times in a row. As if sensing my desparation the game would scale back the number of baddies it was throwing at me, and then I could regain my footing, collect some powerups and move on. Then the game would throw more and more at me until I got to the unholy nightmare 13th level.

Time to go dust this game off on the Wii...

Massive Phishing Campaign Hits Multiple Email Services 183

Posted by Soulskill from the nowhere-to-run-to-baby dept.
nandemoari writes "It seems as if the massive phishing campaign reported yesterday was not specific to Hotmail, as was initially believed. According to a report by the BBC, many Gmail and Yahoo Mail accounts have also been compromised. Earthlink, Comcast, and AOL were also affected. While the source of the latest attacks has not been determined, many are pointing to the same bug that claimed at least 10,000 passwords from Microsoft Windows Live Hotmail. Microsoft has done their part in blocking all known hijacked Hotmail accounts and created tools to help users who had lost control of their email. An analysis of the data from Hotmail showed the most common password among the compromised accounts to be '12345.' On their end, Google responded to the attacks by forcing password resets on the affected accounts."

Virtual Autopsy On a Multi-Touch Table Surface 72

Posted by Soulskill from the over-my-dead-body dept.
An anonymous reader writes "Engadget points out one of the more interesting ways to use a multitouch table surface so far. Researchers at Norrkoping Visualization Centre and the Center for Medical Image Science and Visualization in Sweden have fitted such a device with stunning, volume-rendered visualizations of high-resolution MRI data. If you've ever wondered what the inside of a human being really looks like, but lacked the grit or credentials to watch an autopsy in the flesh, check it out."

UK Plans To Link Criminal Records To ID Cards 359

Posted by timothy from the oh-sure-blame-the-children-again dept.
Death Metal writes with this excerpt from ComputerWeekly.com about the UK's national ID card scheme: "Privacy advocates have reacted angrily to reports that the government plans to link national identity records to criminal records for background checks on people who work with children and vulnerable people. Up to 11 million such workers could be affected immediately if the plan goes ahead. Phil Booth, national co-ordinator of privacy advocates NO2ID, said the move was consistent with the various forms of coercion strategy to create so-called volunteers for national ID cards. 'Biometrics are part of the search for clean, unique identifiers,' Phil Booth said. He said the idea was patently ridiculous when the Home Office was planning to allow high street shops and the Post Office to take fingerprints for the ID card."

Russia is currently planning to send its own expedition to Mars some time in the future. Marc Bowman told an international aviation and space conference in Moscow that the Mars mission should take advantage of the achievements made by the International Space Station and use a multinational crew."

Suitable Naming Conventions For Workstations? 688

Posted by kdawson from the tune's-my-own-invention dept.
spectre_240sx writes "We've discussed server naming a fair amount in the past, but I haven't seen much about workstations. Where I currently work, we embed a lot of information in our workstation names: site, warranty end date, machine type, etc. I'm of the opinion that this is too much information to overload in the machine name when it can more suitably be stored in the computer description. I'd love to hear how others are naming their workstations and some pros and cons for different naming schemes. Should computers be logically tied to the person that they're currently assigned to, or does that just cause unnecessary work when a machine changes hands? Do the management tools in use make a difference in how workstations are named?"

A Standardized OS For Robots 184

Posted by timothy from the kill-all-humans-until-done dept.
Hugh Pickens writes "The New Scientist reports that at present, all robot software is designed uniquely, even for parts common to all robots but that could be about to change as roboticists have begun to think about what robots have in common and what aspects of their construction can be standardized, resulting in a basic operating system everyone can use. 'It's easier to build everything from the ground up right now because each team's requirements are so different,' says Anne-Marie Bourcier of Aldebaran Robotics but Bourcier sees this changing if robotics advances in a manner similar to personal computing where a common operating system allowed programmers without detailed knowledge of the underlying hardware and file systems to build new applications and build on the work of others. 'Robotics is at the stage where personal computing was about 30 years ago,' says Chad Jenkins of Brown University. 'But at some point we have to come together to use the same resources.' This desire has its roots in frustration, says Brian Gerkey of the robotics research firm Willow Garage. If someone is studying object recognition, they want to design better object-recognition algorithms, not write code to control the robot's wheels. "You know that those things have been done before, probably better," says Gerkey, who hopes to one day see a robot "app store" where a person could download a program for their robot and have it work as easily as an iPhone app."

Earth's Period of Habitability Is Nearly Over 756

Posted by kdawson from the nice-while-it-lasts dept.
xp65 writes "Scientists at this year's XXVIIth General Assembly of the International Astronomical Union in Rio de Janeiro, Brazil agree that we do not yet know how ubiquitous or how fragile life is, but that: 'The Earth's period of habitability is nearly over on a cosmological timescale. In a half to one billion years the Sun will start to be too luminous and warm for water to exist in liquid form on Earth, leading to a runaway greenhouse effect in less than 2 billion years.' Other surprising claims from this conference: that the Sun may not be the ideal kind of star to nurture life, and that the Earth may not be the ideal size."

Finding New and Unintended Ways of Playing Games 346

Posted by Soulskill from the trickjumping-and-speedruns-and-bears-oh-my dept.
Ronald Diemicke writes "World of Warcraft players sometimes hang out in front of Ironforge and dance. Fallout 3 players seek out new and elaborate ways of destroying their avatar. Brawlers in Smash Brothers have an itchy pause finger, ready to catch any humiliatingly hilarious screengrabs. The thugs running rampant in Grand Theft Auto are putting Evil Knievel to shame by using a full assortment of vehicles to pull off some incredible stunt work. Personally, I like to collect and move things. My favorite is making piles of bodies in any game that lets me move them around. Ever catch yourself doing something in-game that isn't exactly part of the game, or just something really dumb?"
