Submission + - Ray tracing for gaming explored (pcper.com) 3

Vigile writes: "Ray tracing is still thought of as the 'holy grail' for real-time imagery but because of the intense amount of calculations required it has been plagued with long frame render times. This might soon change, at least according to an article from Daniel Pohl, a researcher at Intel. With upcoming many-core processors like Intel's Larrabee he believes that real-time ray tracing for games is much closer than originally thought thanks in large part to the efficiency it allows with spatial partitioning and reflections when compared to current rasterization techniques. Titles like Valve's Portal are analyzed to see how they could benefit from ray tracing technology and the article on PC Perspective concludes with the difficulties combing the two rendering techniques as well as a video of the technology in action."

Submission + - Microsoft deprecating some OOXML functionality (fanaticattack.com)

christian.einfeldt writes: "According to open standards advocate Russell Ossendryver, Microsoft will be deprecating certain functionality in its Microsoft Office Open XML specification. Ossendryver says the move is an attempt to quiet critics of the specification in the run up to the crucial February vote as to whether Microsoft OOXML will be included as a second standard for e-documents, along with the existing ODF ISO standard. ECMA, the Microsoft-led industry standards group formally offering OOXML to ISO, confirms in a 21 December 2007 announcement that issues related to the "leap year bug", VML, compatibility settings such as "AutoSpaceLikeWord95" and others will be "extracted from the main specification and relocated to an independent annex in DIS 29500 for deprecated functionality." Ossendryver is not convinced that deprecation will work, calling the deprecation proposal a 'smoke screen' and a 'bomb disguised as a standard' because 'every application will need to support the deprecated features in order to read files with the deprecated features.' Ossendryver also points out that legacy formatted Microsoft Office documents will still remain non-standard under the new proposal for deprecation."

Submission + - Technology in 2008 (economist.com)

mrcgran writes: "The Economist has an article with technology predictions for 2008: " 1. Surfing will slow: The internet is not about to grind to a halt, but as more and more users clamber aboard to download music, video clips and games, ... surfing the web is going to be more like travelling the highways at holiday time. You'll get there, eventually, but the going won't be great. 2. Surfing will detach: Internet will doubtless be as popular among mobile-internet surfers as among their sedentary cousins. 3. Surfing — and everything else computer-related — will open: Rejoice: the embrace of "openness" by firms that have grown fat on closed, proprietary technology is something we'll see more of in 2008. The trend toward openness has been given added impetus by the recent collapse of the legal battles brought by SCO. The verdict removed, once and for all, the burden that had been inhibiting Linux's broader acceptance. Since the verdict against SCO, Linux has swiftly become popular in small businesses and the home, largely the doing of Ubuntu 7.10. And because it is free, Linux become the operating system of choice for low-end PCs. Neither Microsoft nor Apple can compete at the new price points being plumbed by companies looking to cut costs.""

Submission + - Only 2 in 500 College Students Believe in IP (nytimes.com) 1

I Don't Believe in Imaginary Property writes: "David Pogue of the New York Times has an interesting story about how fewer and fewer people believe that infringement is wrong. He mentions talks he gave back in 2005 where people were willing to believe that making backups of DVDs you own is wrong. Today, however, at his talks, he was only able to get two people out of a crowd of five hundred college students to say that downloading a movie or album is wrong. He goes on, like many before him, to bemoan the immorality of young people today, saying: "I do know, though, that the TV, movie and record companies' problems have only just begun. Right now, the customers who can't even *see* why file sharing might be wrong are still young. But 10, 20, 30 years from now, that crowd will be *everybody*. What will happen then?""

Submission + - OLPC a hit in remote Peruvian village (chicagotribune.com)

mrcgran writes: "Chicago Tribune is running a story about the effects of OLPC on a remote village in Peru: "Doubts about whether poor, rural children really can benefit from quirky little computers evaporate as quickly as the morning dew in this hilltop Andean village, where 50 primary school children got machines from the One Laptop Per Child project six months ago. At breakfast, they're already powering up the combination library/videocam/audio recorder/music maker/drawing kits. At night, they're dozing off in front of them — if they've managed to keep older siblings from waylaying the coveted machines. Peru made the single biggest order to date — more than 272,000 machines — in its quest to turn around a primary education system that the World Economic Forum recently ranked last among 131 countries surveyed." A detailed log has been kept and a youtube video is also available."

Submission + - Researchers Simulate Rat's Brain (guardian.co.uk) 3

slick_shoes writes: Researchers working on the 'Blue Brain' project have developed a computer simulation of the neocortical column — the basic building block of the neocortex, the higher functioning part of our brains — of a two-week-old rat, and it behaves exactly like its biological counterpart. The machine that simulates this column is an IBM Blue Gene/L supercomputer. Project director Henry Markram believes that with the state of technology today, it is possible to build an entire rat's neocortex. From there, it's cats, then monkeys and finally, a human brain.

Submission + - Four months of Ubuntu on Dell (lxer.com)

mrcgran writes: "LXer has an interview with John Hull, a manager of the Linux Engineering team at Dell, where he reports on how the Ubuntu machines have been working out for them so far. "Embracing Ubuntu Linux on our desktops and laptops seems to have really raised Dell's visibility within the Linux community. We have been supporting, testing, developing for, and selling Linux for 8+ years here at Dell, but before the Ubuntu announcement, a lot of people didn't know that we did any of that. (...) Previous to our Ubuntu product announcement, it was much more difficult to extend this model to consumer desktop and laptop technologies. We would have a conversations with vendors about pushing Linux support for their hardware, but without a Linux product offering from Dell for that hardware, it was very difficult to convince them to release Linux drivers. That has certainly changed now that we offer Ubuntu Linux, and we are making much more progress in our vendor discussions. (...) The original sales estimates for Ubuntu computers was around 1% of the total sales, or about 20,000 systems annually. The program so far is meeting expectations. Customers are certainly showing their interest and buying systems preloaded with Ubuntu, but it certainly won't overtake Microsoft Windows anytime soon.""

Submission + - Japan Moon Probe Snaps First Photos (space.com)

mrcgran writes: "Space.com reports: "Almost one month after Japan's successful launch of the Kaguya lunar probe, the unmanned observatory has begun its first major activities in orbit around the moon. In addition to snapping its first lunar images, the probe jettisoned one of two 110-pound (50-kilogram) "baby" satellites that will help create a detailed gravity map of the moon." The major objectives of the "KAGUYA" mission are to obtain scientific data of the lunar origin and evolution and to develop the technology for the future lunar exploration. "KAGUYA" consists of a main orbiting satellite at about 100km altitude and two small satellites (Relay Satellite and VRAD Satellite) in polar orbit."

Submission + - Real-time raytracing for PC games almost a reality (pcper.com) 1

Vigile writes: "Real-time raytracing has often been called the pinnacle for computer rendering for games but only recently has it been getting traction in the field. A German student, and now Intel employee, has been working on raytraced versions of the Quake 3 and Quake 4 game engines for years and is now using the power of Intel's development teams to push the technology further. With antialiasing implemented and anisotropic filtering close behind, they speculate that within two years the hardware will exist on the desktop to make "game quality" raytracing graphics a reality."

Submission + - Dell laptops still exploding (consumeraffairs.com)

bl8n8r writes: "It "looked like fireworks which would have been cool had it not been in my house." said Doug Brown of Columbus, Ohio. Brown, a Network Administrator, called 911 last week when the Dell 9200 laptop burst into flames in his house. Emergency response units included two pumpers, a ladder truck, a bamalance, the HAZMAT unit, and a battalion chief. When Doug phoned Dell to inquire about liability, he was asked if he had insurance. It's not clear if Doug's laptop is one of the earlier models recalled by Dell; a Macbook is cited in TFA for allegedly burning down a house in Australia as well as another instance of a suspect Dell laptop burning down a pickup truck in Nevada. If the burning battery issues are going to continue to be a problem, who's going to be responsible for losses? Insurance companies, Laptop makers, Battery vendors, and consumer negligence could presumably be cited in all cases."

Submission + - MS responds to Vista's network and audio problems. (zdnet.com)

quirdan writes: With the publishing of the discovery of the connection between Vista's poor networking performance and audio activities last week, word quickly spread around the Internet. No doubt this grabbed Microsoft's attention, and they have decided to respond to the issue. Microsoft state they are working on a technical documentation, as well as applying a slight sugar coating to the symptoms. Apparently they believe almost a 90% drop in networking performance is "slight," only affects reception of data, and that this performance trade-off is necessary to simply play an MP3 or a Windows 'ding' sound. Come on — this is 2007, not 1997.

Submission + - Skype-Linux reads /etc/passwd and firefox profile! (skype.com)

mrcgran writes: "Users of Skype for Linux have just found out that it reads the files /etc/passwd, firefox profile, plugins, addons, etc, and many other unnecessary files in /etc. This fact was originally discovered by using AppArmor, but others have confirmed this fact using strace on versions 1.4.0.94 and 1.4.0.99. What is going on? This probably shows how important it is to use AppArmor in any closed-source application in Linux to restrict any undue access to your files."
