Submission + - The Hysteria of the Cyber-Warriors (bostonreview.net)

Willfro writes: Evgeney Morozov has a piece up now at Boston Review about the hyperbole and reality of "cyber war".

"At the end of May, President Obama called cyber-security 'one of the most serious economic and national security challenges we face as a nation.' His words echo a flurry of gloomy think-tank reports. Unfortunately, these reports are usually richer in vivid metaphor--with fears of "digital Pearl Harbors" and "cyber-Katrinas"--than in factual foundation.

So why is there so much concern about "cyber-terrorism"? Answering a question with a question: who frames the debate? Much of the data are gathered by ultra-secretive government agencies--which need to justify their own existence--and cyber-security companies--which derive commercial benefits from popular anxiety. Journalists do not help. Gloomy scenarios and speculations about cyber-Armaggedon draw attention, even if they are relatively short on facts.

Submission + - Comets Probably Seeded Earth's Nitrogen Atmosphere (technologyreview.com)

KentuckyFC writes: "One of the biggest puzzles of astrobiology is the origin of the Earth's oceans and atmosphere. One favoured theory is that our water is the leftovers from a bombardment of comets early in Earth's history. But the ratio of hydrogen and deuterium in the oceans doesn't match the ratio in the four comets measured so far (Halley's, Hyakutake, Hale-Bopp and C/2002 T7 LINEAR). Now a new analysis of the ratio of nitrogen-14 and 15 isotopes in these comets and on Earth places new limits on how much of our environment could have come from comets. On the one hand, the astronomers who did the work say that no more than a few percent of Earth's water could have come from comets. But on the other, they say that the ratio of nitrogen isotopes in these comets almost exactly matches the ratio in Earth's atmosphere. That suggests that while Earth's oceans must have come from somewhere else, Earth's early atmosphere was probably seeded by comets."

Submission + - The Galaxy's 62-Million Year Extinction Oscillator

Hugh Pickens writes: "Cosmologist Adrian Mellott has an interesting article in Seed Magazine where he discusses his search for the mechanism behind the mass extinctions in earth's history that seem to occur with a period of about 62 million years. Scientists have identified nearly 20 mass extinctions throughout the fossil record including the end-Permian event about 250 million years ago that killed off about 95 percent of life on Earth and the mass extinction at end of the Cretaceous period 65 million years ago when dinosaurs' domination of the earth reached its end. Mellott notes that as our solar system slowly orbits the Milky Way's center, it oscillates through the galactic plane with a period of around 65 million years. "The space between galaxies is not empty. It's actually full of rarefied hot gas," says Mellott. "As our galaxy falls into the Local Supercluster, it should disturb this gas and create a shock wave, like the bow shock of a jet plane" generating cascades of high-energy subatomic particles and radiation called "cosmic rays" causing enhanced cloud formation and depletion of the ozone layer killing off many small organisms at the base of the food chain and potentially leading to a population crash. So where is the earth now in the 62-million year extinction cycle? "If the past is any guide, we are on the downside of biodiversity, a few million years from hitting bottom," writes Mellott. "We now must try to understand the 62-million year cycle itself by seeking correlations with things like the rate of seabed fossil formation or the rates of species origination and extinction. Only by gathering these clues can we fathom the diversity recession that seems to lie in our geological future.""

Submission + - EXT4, Btrfs, NILFS2 Performance Benchmarks (phoronix.com)

An anonymous reader writes: Phoronix has published Linux filesystem benchmarks comparing XFS, EXT3, EXT4, Btrfs and NILFS2 filesystems. This is the first time that the new EXT4 and Btrfs and NILFS2 filesystems have been directly compared when it comes to their disk performance though the results may surprise. For the most part, EXT4 came out on top.

Submission + - Firefox Standard Will Combat Cross-Site-Scripting (technologyreview.com)

Al writes: "The Mozilla foundation is to adopt a new standard to help web site's prevent cross site scripting (XSS) attacks. The standard, called Content Security Policy (CSP), will let a website specify what Internet domains are allowed to host the scripts that run on its pages. This breaks with Web browsers' tradition of treating all scripts the same way by requiring that websites put their scripts in separate files and explicitly state which domains are allowed to run the scripts. The Mozilla Foundation selected the implementation because it allows sites to choose whether to adopt the restrictions. "The severity of the XSS problem in the wild and the cost of implementing CSP as a mitigation are open to interpretation by individual sites," Brandon Sterne, security program manager for Mozilla, wrote on Mozilla Security Blog. "If the cost versus benefit doesn't make sense for some site, they're free to keep doing business as usual."

Submission + - Comcast bringing metropolitan WiMAX to subscribers (reuters.com)

RickRussellTX writes: "Comcast plans to offer 4 megabits/sec WiMAX services to customers in Portland, Oregon starting tomorrow. Branded as "Comcast High-Speed 2go" and "4G", the service will require a $44.99 per month subscription in addition to existing Comcast home service. For $69.99 they will offer a dual-mode card with access to both Comcast WiMAX and Sprint's national 3G wireless network. Future rollouts are planned for Chicago, Philadelphia, and Atlanta.

Say what you will about Comcast (and I know many Slashdot readers have plenty to say about Comcast), this is a daring attempt to bypass entrenched cell phone companies with a direct-to-consumer wireless service."

Submission + - Wikipedia Censored To Protect Captive Reporter (nytimes.com)

AI writes: For seven months, The New York Times managed to keep out of the news the fact that one of its reporters, David Rohde, had been kidnapped by the Taliban. But that was pretty straightforward compared with keeping it off Wikipedia....A dozen times, user-editors posted word of the kidnapping on Wikipedia's page on Mr. Rohde, only to have it erased. Several times the page was frozen, preventing further editing — a convoluted game of cat-and-mouse that clearly angered the people who were trying to spread the information of the kidnapping....The sanitizing was a team effort, led by Jimmy Wales, co-founder of Wikipedia, along with Wikipedia administrators and people at The Times.

Submission + - Being Overweight May Lead to Longer Life 3

Hugh Pickens writes: "Findings of a new study show that underweight people and those who are extremely obese die earlier than people of normal weight — but those who are overweight actually live longer than people of normal weight. "It's not surprising that extreme underweight and extreme obesity increase the risk of dying, but it is surprising that carrying a little extra weight may give people a longevity advantage," said one of the coauthors of the study. "It may be that a few extra pounds actually protect older people as their health declines, but that doesn't mean that people in the normal weight range should try to put on a few pounds." The study examined the relationship between body mass index and death among 11,326 adults in Canada over a 12-year period. The study showed that underweight people were 70 percent more likely than people of normal weight to die, and extremely obese people were 36 percent more likely to die. But overweight individuals defined as a body mass index of 25 to 29.9 were 17 percent less likely to die than people of a normal weight defined as a BMI of 18.5 to 24.9. The relative risk for obese people was nearly the same as for people of normal weight. The authors controlled for factors such as age, sex, physical activity, and smoking. "Overweight may not be the problem we thought it was," said Dr. David H. Feeny, a senior investigator at Kaiser Permanente Center for Health Research. "Overweight was protective.""

Submission + - Does The 'Hacker Ethic' Harm Today's Developers? (infoworld.com)

snydeq writes: "Fatal Exception's Neil McAllister questions whether the 'hacker ethic' synonymous with computer programing in American society is enough for developers to succeed in today's economy. To be sure, self-taught 'cowboy coders' — the hallmark of today's programming generation in America — are technically proficient, McAllister writes, 'but their code is less likely to be maintainable in the long term, and they're less likely to conform to organizational development processes and coding standards.' And though HTC's Vineet Nayar's proclamation that American programmers are 'unemployable' is overblown, there may be wisdom in offering a new kind of computer engineering degree targeted toward the student who is more interested in succeeding in industry than exploring computing theory. 'American software development managers often complain that Indian programmers are too literal-minded,' McAllister writes, but perhaps Americans have swung the pendulum too far in the other direction. In other words, are we 'too in love with the hacker ideal of the 1980s to produce programmers who are truly prepared for today's real-life business environment?'"

Submission + - Sony Begins Shipping PCs With Green Dam In China (informationweek.com)

Dotnaught writes: "Sony is now shipping computers in China with Green Dam installed, in advance of the Chinese government's July 1 deadline. But the company is disclaiming responsibility for any damage caused by the Web filtering software. Documents posted by Hong Kong-based media studies professor Rebecca MacKinnon also suggest that the Chinese government is considering similar filtering requirements for mobile phones."

True; I meant not give a damn as in shooting unarmed protesters and beating them, to terrify them and stop them from taking to the streets. Which is unfortunately, what seems to be happening. The main outcome of this seems to be showing the rest of us, outside Iran, that there are a good number of people who are opposed to the present regime; 30 years ago, this was not the case. The definitive role of a repressive government is to repress its' people

What, you mean like Tieneman Square? As I recall, that didn't work out so well....and unfortunately, brick and chain does not really work when the other side has guns and ammunition galore. Public demonstration is all fine and good if the powers that be are not willing to meet unarmed citizens with massive firepower; but the sad truth is that totalitarian governments are determined to stop dissent regardless of the body count. If you don't give a damn about world opinion, there is very little to prevent you from extreme military over reaction to keep the status quo.

Point taken. I was exaggerating to make a point; many internet users are in fact teens and tweens (who have no concept of what MAD even means), and given the apalling knowledge by the lumpenproletariat, and students, of geopolitics, geography, and anything outside the realm of TMZ coverage, I have a suspicion that there would in fact be less interest...though I hope the point is never put to the test...
