Garin writes "The late Permian saw the greatest mass extinction event of all-time. The causes for this extinction are hotly debated, but one key piece of the puzzle has recently been revealed: while the deep-water environments were anoxic, shallower waters showed clear signs of being oxygenated. This rules out global anoxia, and strongly suggests that other factors, such as the Siberian Traps vulcanism, must have played a dominant role. From the article: 'Rather than the direct cause of global extinction, anoxia may be more a contributing factor along with numerous other impacts associated with Siberian Traps eruption and other perturbations to the Earth system.' See the full research article (behind a paywall) here."
First time accepted submitter faffod writes "Coming from a background of console development, where memory management is a daily concern, I found it interesting that there was any doubt that memory management on a constrained system, like a mobile device, would be a concern. Drew Crawford took the time to document his thoughts, and though there is room for some bikesheding, overall it is spot on. Plus it taught me what bikeshedding means."
PolygamousRanchKid writes with this except from the Economist: "Only 10% of internet entrepreneurs across the world are women, according to Startup Compass, a firm that tracks such things. Except in Amman and other Middle Eastern cities, it seems. There, the share of women entrepreneurs is said to average 35% — an estimate seemingly confirmed by the mix of the sexes at 'Mix'n'Mentor,' a recent gathering in the Jordanian capital organised by Wamda, an online publication for start-ups. Reasons abound, and they are not always positive, says Nina Curley, Wamda's editor. Although more than half of university graduates in many Middle Eastern countries (51% in Jordan) are women, the workforce is dominated by men (women provide only 21% of it overall, and a paltry 16% in Jordan). The internet, however, is a new space that is more meritocratic and not as heavily male. The technology also lets entrepreneurs work from home, making it easier to raise children."
theodp writes "Widely deployed in Iraq and promoted by military leaders, BusinessWeek reports the ADE 651 bomb-detecting device had one little problem: it wouldn't detect explosives (earlier Slashdot story). 'The ADE 651,' reports Adam Higginbotham, 'was modeled on a novelty trinket conceived decades before by a former used-car salesman from South Carolina, which was purported to detect golf balls. It wasn't even good at that.' One thing the ADE 651 did excel at, however, was making money — estimates suggest that the authorities in Baghdad bought more than 6,000 useless bomb detectors, at a cost of at least $38 million. Even though ADE 651 manufacturer James McCormick was found guilty of three counts of fraud and sentenced to 10 years in prison in May, the ADE 651 is still being used at thousands of checkpoints across Baghdad. Elsewhere, authorities have never stopped believing in the detectors. Why? According to Sandia Labs' Dale Murray, the ideomotor effect is so persuasive that for anyone who wants or needs to believe in it, even conclusive scientific evidence undermining the technology it exploits has little power."
symbolset writes "Discovery News is covering a project by two engineers from the University of Michigan to pair cubesats with tiny ion engines for inexpensive interplanetary exploration. The tiny plasma drive called the CubeSat Ambipolar Thruster (CAT) will ionize water and use it as propellant with power provided by solar cells. In addition to scaling down the size of ion engines they hope to bring down the whole cost of development and launch to under $200,000."
McGruber writes "Thursday, The Verge broke the news that Microsoft was slashing the price of its tablets — the price of the 32-gig Surface RT plummeted by 42%! Staples, TigerDirect and many other retailers are already selling the tablets at the lowered prices. I wonder what Microsoft will do for customers who purchased a tablet right before the price drop?"
First time accepted submitter ChrisC1234 writes "My grandparents are getting older and don't get out much anymore, and with the demise of video stores (and not even understanding what a RedBox is), they don't see movies anymore. They've got internet access, so I'm thinking of getting them a streaming appliance and a Netflix account. So I'm wondering what device is the easiest for elderly people to use. I'm thinking either a Roku or Apple TV, but open to other options. It just needs to be easy to navigate and support closed captioning. Has anyone else done this successfully?"
MojoKid writes with word that "A tech demo posted to YouTube shows off Motorola's upcoming Moto X smartphone, a seemingly high-end device that is sure to win over a few fans with its wealth of new tricks and features. The Moto X handset, which is launching exclusive to Rogers in Canada (no mention of U.S. market carriers) this August, will be available in black and white, but a key selling point of the device comes from its voice activated features. The tech demo heavily emphasizes Google Now, which Moto X users can engage without touching the device. In the demo, a woman is shown asking Google Now what the weather will be like in Toronto while she types away on a computer, never having to reach down to tap the handset. It was also previously leaked that the Moto X will ship with a 4.4-inch display (1280x720), 1.7GHz dual-core Qualcomm Snapdragon 8960 processor, 2GB of RAM, 16GB of internal storage, 10MP rear-facing camera, 2MP front-facing camera, and of course Android 4.2 Jelly Bean." With a marketing budget said to include up to half a billion (!) dollars from Google, it's hard to imagine that any leaks are actually unintentional.
HonorPoncaCityDotCom writes "Nicole Perlroth and David E. Sanger write in the NY Times that all over the world, from South Africa to South Korea, business is booming in zero days. The average attack persists for almost a year before it is detected, according to Symantec, the maker of antivirus software. Until then it can be exploited or 'weaponized' by both criminals and governments to spy on, steal from, or attack their targets. Ten years ago, hackers would hand knowledge of such flaws to Microsoft and Google free in exchange for a T-shirt, but increasingly the market for 0-day exploits has begun to migrate into the commercial space (PDF) as the market for information about computer vulnerabilities has turned into a gold rush. Companies like Vupen charge customers an annual $100,000 subscription fee to shop through its catalog, and then charges per sale to countries who want to use the flaws in pursuit of the kind of success that the United States and Israel achieved three summers ago when they attacked Iran's nuclear enrichment program with a computer worm that became known as 'Stuxnet.' Israel, Britain, Russia, India and Brazil are some of the biggest spenders but North Korea is also in the market, as are some Middle Eastern intelligence services."
lemur3 writes "State legislators in Colorado have not been receiving speeding tickets due to inadequacies in the implementation of a DMV database. The current system ties plates to vehicles rather than to individuals, the special plates for legislators are issued to individuals. The result is that there is no entry in the database for the special plates when the automated photo radar system is triggered, this means nobody receives a citation. In one case a Colorado resident, who had vanity plates reading '33,' received the photo radar citations intended for Senator Mike Johnston representing district 33, whose vehicle was identified by a '33' on his special plate. Lt. Matt Murray of the Denver Police, speaking of the system commented, 'Our system works, the database works. What needs to happen is the state's database need to be complete.'"
DeviceGuru writes with an excerpt that may be of interest especially for mobile users with cheap, always available wireless data: "An OpenWRT Linux-based hardware adapter called Plug designed for unifying USB-connected storage met its $69,000 Kickstarter pledge goal in 12 hours. The tiny Plug device eschews cloud storage for a localized approach whereby an app or driver installed on each participating computer or mobile device intercepts filesystem accesses, and redirects data reads and writes to storage drives attached to the user's Plug device. The Plug enjoyed one of the fastest fulfillments in Kickstarter history, meeting its goal in 12 hours, and has already soared to over $223,000 in funding."
Freshly Exhumed writes "Elon Musk's dream of a hyperloop transport system seems to be closer to reality than he anticipated. Hyperloop transportation, referred to by Musk as a "cross between a Concorde, a railgun, and an air hockey table", is a tubular pneumatic transport system with the theoretical capability of carrying passengers from New York to L.A. in about 30 minutes at velocities near 4,000 miles per hour, while maintaining a near-continuous G force of 1. Colorado-based company ET3 is planning to build and test its own version of such a hyperloop system, Yahoo reports." A more critical article would point out that the numbers presented seem absurdly optimistic; $100 for a 4,000mph cross country trip may be "projected," but construction of a cross-country train tube is a long way off, and so are ticket sales.
First time accepted submitter osho741 writes "I was wondering if anyone has enterprise level networking devices set up at home? I seem to go through at least 1 wireless consumer grade router a year or so. I can never seem to find one that last very long under just normal use. I thought maybe I would have better luck throwing together a network using used enterprise equipment. Has anyone done this? What would you recommend for a network that maxes out at 30mbps downstream from the ISP and an internal network that should be able to stream 1080p movies to 3 or 4 devices from a media server? Any thoughts and or suggestions are welcome."
First time accepted submitter Davak writes "In many ways finding the small amount of terrorists within the United States is like screening a population of people for a rare disease. A physician explains why collecting excessive data is actually dangerous. Each time a test is run, the number of people incorrectly identified quickly dwarfs the correct matches. Just like in medicine, being incorrectly labelled has serious consequences."
HighOrbit writes "Engadget reports that the consortium behind Hulu have issued a press release and have taken Hulu off the market. The current owners will maintain their joint ownership of the video streaming service. Hulu is currently a joint project of Fox, Disney (ABC), and Comcast (NBC-Universal). Instead of selling off Hulu, the consortium will inject $750 Million to grow the streaming service. Slashdot previously reported possible buyers rumored to be Yahoo, DirecTV, Time Warner Cable, and Chernin Group/AT&T. Additionally Bloomberg reports that Time Warner Cable is still interested and seeks to join the current consortium by acquiring a 25% stake."
