Shiny New Space Fence To Monitor Orbiting Junk 76

coondoggie writes "Some work has begun on tracking and detecting the overabundance of space junk which has become a growing priority as all manner of satellites, rockets and possible commercial space shots are promised in the coming few years. Today Northrop Grumman said it grabbed $30 million from the US Air Force to start developing the first phase of a global space surveillance ground radar system. The new S-Band Space Fence is part of the Department of Defense's effort to detect and track what are known as resident space objects (RSO), consisting of thousands of pieces of space debris as well as commercial and military satellites. The new Space Fence will replace the current VHF Air Force Space Surveillance System built in 1961."

World's Oldest Tattoo Written In Soot 68

ewenc writes "A series of tattoos belonging to Otzi the 5300 year-old Tyrolean Iceman are made of soot, reports New Scientist. Mountain climbers discovered Otzi's mummified body in the Austrian-Italian alps in 1991. What's left of his skin was littered with simple cross and line markings. Electron microscopy and spectroscopy now show that Otzi's tats are made of double-bonded carbon indicative of soot, as well as silicate crystals that probably came from rocks surrounding a fire pit."

Rotten Office Fridge Cleanup Sends 7 To Hospital Screenshot-sm 410

bokske writes "An office worker cleaning a fridge full of rotten food created a smell so noxious that it sent seven co-workers to the hospital and made many others ill. Firefighters had to evacuate the AT&T building in downtown San Jose on Tuesday, after the flagrant fumes prompted someone to call 911. A hazmat team was called in. Just another day at the office."

Why Bother With DRM? 376

Brad Wardell of Stardock and Ron Carmel of 2D Boy recently spoke with Gamasutra about their efforts to move the games industry away from restrictive DRM. Despite the fact that both have had their own troubles with piracy, they contend that overall piracy rates aren't significantly affected by DRM — and that most companies know it. Instead, the two suggest that most DRM solutions are still around to hamper a few more specific situations. Quoting: "'Publishers aren't stupid. They know that DRM doesn't work against piracy,' Carmel explains. 'What they're trying to do is stop people from going to GameStop to buy $50 games for $35, none of which goes into the publishers' pockets. If DRM permits only a few installs, that minimizes the number of times a game can be resold.' ... 'I believe their argument is that while DRM doesn't work perfectly,' says Wardell, 'it does make it more difficult for someone to get the game for free in the first five or six days of its release. That's when a lot of the sales take place and that's when the royalties from the retailers are determined. Publishers would be very happy for a first week without "warez" copies circulating on the Web.'"

Submission + - IBM Pares Speed Gap in Memory Circuitry

Carl Bialik from WSJ writes: "IBM researchers are claiming a breakthrough in developing circuitry to store data on future microprocessor chips, the Wall Street Journal reports. From the article: 'Exploiting a manufacturing technology called silicon-on-insulator, the company has developed unusually fast DRAM circuitry for use as cache memory. Subramanian Iyer, a director of IBM's manufacturing-process development, estimates it takes 1.5 nanoseconds — or billionths of a second — to fetch data from its enhanced DRAM technology, compared with 10 to 12 nanoseconds for conventional DRAMs and 0.8 to 1 nanoseconds for SRAMs. Mr. Iyer said three times more data can be stored in the same amount of space by switching from SRAM to DRAM circuitry; he expects the technology to be incorporated on microprocessors that will be manufactured next year using a new production process.'"

Submission + - D-Wave unveils 16-qubit quantum computer

Coucho writes: "An article on The Register gives the scoop on D-Wave System's latest quantum computer with the processing power of 16 quantum bits (or qubits). D-Wave's CTO Geordie Rose stated that "Even millions of qubits today today would consume less power than off-the-shelf processors," but then added "The cooling systems used for past computers are far harder to build and more complicated". Is this a farce? Or is this straight out of science-fiction? You decide. Article: http://www.theregister.co.uk/2007/02/13/dwave_quan tum/"

Submission + - Deputy: Type and Memory Safety for C Programs

An anonymous reader writes: Deputy is a C compiler built by researchers at UC Berkeley that uses simple programmer-supplied annotations to catch type and memory errors such as buffer overflows and misuse of union types. For example, if you write a function that takes a buffer and its length as arguments, you can annotate the buffer's type to indicate that its length is stored in the second argument. Using these annotations, Deputy will either verify accesses to this buffer at compile time or insert the required run-time checks. Deputy has already been used on several Linux device drivers and has a corresponding recovery system for Linux called SafeDrive.
