GPUs Helping To Lower CT Scan Radiation 77

Gwmaw writes with news out of the University of California, San Diego, on the use of GPUs to process CT scan data. Faster processing of noisy data allows doctors to lower the total radiation dose needed for a scan. "A new approach to processing X-ray data could lower by a factor of ten or more the amount of radiation patients receive during cone beam CT scans... With only 20 to 40 total number of X-ray projections and 0.1 mAs per projection, the team achieved images clear enough for image-guided radiation therapy. The reconstruction time ranged from 77 to 130 seconds on an NVIDIA Tesla C1060 GPU card, depending on the number of projections — an estimated 100 times faster than similar iterative reconstruction approaches... Compared to the currently widely used scanning protocol of about 360 projections with 0.4 mAs per projection, [the researcher] says the new processing method resulted in 36 to 72 times less radiation exposure for patients."

The basis for your comment is esteem for the skills required to develop software. I wonder, however, if you underestimate the skills required to write and publish effective criticism. The fundamental nature of open source software is that if you care enough about it to host a blog criticizing it, you will have already deployed a level of skill and effort that could improve the software itself.

AMD To Shed 10% of Its Workforce 276

stress_life writes "Recent rumors about AMD firing 5% of its workforce proved to be understated. AMD just announced that the company is going to deliver pink slips to 1600-1700 workers, or around 10% of its employees. AMD needs revenue of $2 billion per quarter, but Q1'08 is expected to come in around $1.5 billion. These firings have to be complete by Q3'08, the quarter by which Hector Ruiz promised to be profitable." We most recently discussed AMD's struggles in February.

IBM Wants To Patent Restaurant Waits 154

theodp writes "If all goes IBM's way, it'll soon constitute patent infringement if Bennigan's gives you a free lunch for being inconvenienced by a long wait for your meal. Big Blue is seeking a patent for its Method and Structure for Automated Crediting to Customers for Waiting, the purported 'invention' of three IBM researchers, which IBM notes, 'could be implemented completely devoid of computerization or automation of any kind.' Can we count on IBM to withdraw this patent claim, or will Big Blue weasel out of its patent reform pledge again?"

Air Force Seeking Geeks For 'Cyber Command' 524

An anonymous reader writes "Wired reports that the two-star general in charge of the US Air Force's new Cyber Command is looking for hacker-types to beef up its cadre of cyber warriors — no heavy lifting required. 'We have to change the way we think about warriors of the future,' General William Lord says. 'So if they can't run three miles with a pack on their backs but they can shut down SCADA system, we need to have a culture where they fit in.' The Cyber Command is the Air Force's first new Major Command since the early 1990s. Its purpose is to be able to win an electronic war with China and other potential adversaries."

Star Trek-like 'Phraselator' Helps Police 199

coondoggie writes "Yet another Star Trek-like device is making its way into the real world. VoxTec's Phraselator name sounds a bit like something the Three Stooges might have used long ago but no, this PDA-like device was developed through Defense Advanced Research Projects Agency (DARPA) for use in Afghanistan and Iraq by American soldiers for communicating with locals who spoke Farsi, Dari, Pashto and other languages. It is now being used as one tool to help keep the peace between English and non-English speakers by police departments in California, Florida, Nevada. In a nutshell the $2,500 ruggedized Phraselator runs an Intel PXA255 400mHz processor that supports a built-In noise canceling microphone, a VOCON 3200 Speech Recognizer, 1GB removable SD card, 256MB of DRAM Memory and 64MB Flash Memory. It can store up to 10,000 phrases."

Microsoft's Biggest Threat - Google or Open Source? 240

Glyn Moody writes "Google always plays down suggestions that there's any looming clash of the titans between itself and Microsoft. Meanwhile, the search giant is pushing open source in every way it can. They're contributing directly by contributing code to projects and employing top hackers like Andrew Morton, Jeremy Allison and Guido van Rossum, and indirectly through the $60 million fees it pays Mozilla, its Summer of Code scheme and various open source summits held at its offices. Google+OSS: could this be the killer combination that finally breaks Microsoft?"

What If Yoda Ran IBM? 205

Esther Schindler writes to mention that one IT leader who came from big business found himself in quite another world when he transitioned into a smaller business, specifically with respect to the amount of attention from their vendors. He presents an amusing approach with a familiar twist. "Not only are the IBMs of the world leaving money on the table, they're also risking future sales. The IT leaders at small organizations will in many cases be employed by larger organizations someday. Why alienate them? Vendors could engage IT leaders in small organizations now and build brand loyalty. How could they make such a business model work? Let's imagine (with apologies to George Lucas) what Yoda might do if he were running a large consultancy."
