Physicists Discover Universal "Wet-Dog Shake" Rule 97

Dog owners can sleep easy tonight because physicists have discovered how rapidly a wet dog should oscillate its body to dry its fur. Presumably, dogs already know. From the article: "Today we have an answer thanks to the pioneering work of Andrew Dickerson at the Georgia Institute of Technology in Atlanta and a few buddies. But more than that, their work generates an interesting new conundrum about the nature of shaken fur dynamics. Dickerson and co filmed a number of dogs shaking their fur and used the images to measure the period of oscillation of the dogs' skin. For a labrador retriever, this turns out to be 4.3 Hz."

Sorry, left out a critical detail: the amount of disk space that those specs fill up in 3 days. This is all on a single logical drive using LVM to combine multiple physical drives. The total space for storing the events is about 2.5 terabytes. Yes, ZM can be a total whore. But hard drives are SO cheap...

Americans Don't Care About Domestic Spying ? 485

S1mmo+61 writes "Salon is analyzing a Time Magazine article today, a piece that essentially claims Americans do not care about the domestic spying. The analysis of the Time magazine piece (which is longer than the article itself) is interesting, if only as a quick history of domestic spying in the last eight years. 'Time claims that "nobody cares" about the Government's increased spying powers and that "polling consistently supports that conclusion." They don't cite a single poll because that assertion is blatantly false. Just this weekend, a new poll released by Scripps Howard News Service and Ohio University proves that exactly the opposite is true. That poll shows that the percentage of Americans who believe the Federal Government is "very secretive" has doubled in the last two years alone (to 44%)'"

Firefox 3 May Be More Memory Efficient Than Either IE or Opera 370

Edy52285 writes "Ars Technica has an article showing benchmarks pitting Firefox 3 Beta 4 against other browsers. Contenders include IE7, Firefox 2, Opera 9.5 Beta, and Safari 3.0.4 Beta. The piece includes a graph depicting FF3's memory usage well below that of the other browsers. The in-testing browser even trumps Opera, which has long been regarded as the fastest browser around."

Unreal Creator Proclaims PCs are Not For Gaming 705

An anonymous reader writes "TG Daily is running an interesting interview with EPIC founder and Unreal creator Tim Sweeney. Sweeney is anyway very clear about his views on the gaming industry, but it is surprising how sharply he criticizes the PC industry for transforming the PC into a useless gaming machine. He's especially unhappy with Intel, which he says has integrated graphics chipsets that 'just don't work'."

Cat Ownership Correlated With Heart Health 406

Ant tips us to a story making the rounds lately, based on reporting a couple of weeks old, that owning a cat could cut your heart attack risk by one third. No such effect was seen from dog ownership, but the researchers say that could be because there weren't enough dog owners in the study population to provide meaningful statistics. The study: "...analyzed data on 4,435 Americans, aged 30 to 75, who took part in the federal government's second National Health and Nutrition Examination Study, which ran from 1976-1980. According to the data in the survey, 2,435 of the participants either owned a cat or had owned a cat in the past, while the remaining 2,000 had never done so. [The] team then tracked rates of death from all causes, including heart and stroke. Cat owners 'appeared to have a lower rate of dying from heart attacks' over 10 years of follow-up compared to feline-free folk..."

T-Ray Camera Sees Through Clothes, Preserves Privacy 315

Quite a few readers are sending in stories about ThruVision's products, slated to be demonstrated in Britain next week, that are claimed to use Terahertz radiation ("T-rays") to detect foreign objects under clothing, without revealing body details, from a distance of 25 meters and while the subject is in motion. T-rays lie on the electromagnetic spectrum between infrared and microwaves, and are the subject of lively research efforts worldwide. ThruVision says it developed its products in cooperation with the European Space Agency.

The Battle For Wikipedia's Soul 471

njondet recommends an article at The Economist that sheds light on the identity crisis faced by Wikipedia as it is torn between two alternative futures. "'It can either strive to encompass every aspect of human knowledge, no matter how trivial; or it can adopt a more stringent editorial policy and ban articles on trivial subjects, in the hope that this will enhance its reputation as a trustworthy and credible reference source. These two conflicting visions are at the heart of a bitter struggle inside Wikipedia between 'inclusionists,' who believe that applying strict editorial criteria will dampen contributors' enthusiasm for the project, and 'deletionists' who argue that Wikipedia should be more cautious and selective about its entries."
