How Do You Handle Your Enterprise Documentation? 125

Posted by Cliff from the describing-your-infrastructure dept.
An anonymous reader wonders: "I'm curious as to what tools Slashdot readers use to inventory and document their networks? What got me thinking about this is the part VMWare has been taking in data centers. You've got your SAN, various physical and logical networks, various VMs, and so forth. It just adds a new layer of complexity in terms of documentation. I'm curious as to what people have been using as for doing things like documenting how their backups work, LAN settings, FW settings, where and what runs what services, and so forth. How do you blueprint your entire IT infrastructure so that someone brand new could start and figure out what does what?"

The Many and Varied Games We Play 49

foghorn666 writes "Forbes.com has posted a sprawling special report on games, which tackles the subject from several angles, looking at everything from gambling to playing games in a relationship. There is, naturally, a lot on video games, including an original episode of Red Vs. Blue and a funny piece on the dangers of Warcraft addiction. Particularly cool are the interviews with video game luminaries like Peter Molyneux, Sid Meier, and John Romero. Even Duke Nukem came out of hiding to answer a few questions."

Xeons, Opterons Compared in Power Efficiency 98

Posted by Zonk from the nothing-like-some-friday-morning-power-analysis dept.
Bender writes "The Tech Report has put Intel's 'Woodcrest' and quad-core 'Clovertown' Xeons up against AMD's Socket F Opterons in a range of applications, including widely multithreaded tests from academic fields like computational fluid dynamics and proteomics. They've also attempted to quantify power efficiency in terms of energy use over over time and energy use per task, with some surprising results." From the article: "On the power efficiency front, we found both Xeons and Opterons to be very good in specific ways. The Opteron 2218 is excellent overall in power efficiency, and I can see why AMD issued its challenge. Yes, we were testing the top speed grade of the Xeon 5100 and 5300 series against the Opteron 2218, but the Opteron ended up drawing much less power at idle than the Xeons ... We've learned that multithreaded execution is another recipe for power-efficient performance, and on that front, the Xeons excel. The eight-core Xeon 5355 system managed to render our multithreaded POV-Ray test scene using the least total energy, even though its peak power consumption was rather high, because it finished the job in about half the time that the four-way systems did. Similarly, the Xeon 5160 used the least energy in completing our multithreaded MyriMatch search, in part because it completed the task so quickly. "

Submission + - Canadian scientists reverse Diabetes in mice

Submitted by AvgGatsby
AvgGatsby writes: Researchers working on a "breakthrough" discovery that identifies the role of pain nerves in the cells that produce insulin have prevented and reversed diabetes in mice.

Researchers concluded that the pain receptors don't secrete enough neuropeptides — chemical elements found in the brain — to keep the pancreatic islets, which produce insulin, working normally. Without insulin, humans die, and even the current replacement therapies cannot prevent side effects, such as heart attack, blindness, stroke, loss of limbs and kidney failure.

Given the doomsday warnings we have been hearing about this disease over the past few years this could be a major scientific breakthrough.
