Submitted by Lasrick
Lasrick (2629253) writes "Yousaf Butt, who deconstructed the AP's unsourced graph that alleged nuclear activity in Iran, has a story just posted that takes down the recently reported issue of Iran's alleged attempts to buy 100,000 magnets for its centrifuges (reported in the Washington Post: http://www.washingtonpost.com/world/national-security/iranian-buying-spree-raises-concerns-about-major-expansion-of-nuclear-capacity/2013/02/13/2090805c-7537-11e2-8f84-3e4b513b1a13_story.html)."

Submitted by
Nerval's Lobster
Nerval's Lobster writes "Software developer Jeff Cogswell, who matched up Java and C# and peeked under the hood of Facebook's Graph Search, is back with a new tale: why his team decided to go with Amazon's DynamoDB over MongoDB when it came to building a highly customized content system, even though his team specialized in MongoDB. While DynamoDB did offer certain advantages, it also came with some significant headaches, including issues with embedded data structures and Amazon's sometimes-confusing billing structure. He offers a walkthrough of his team's tips and tricks, with some helpful advice on avoiding pitfalls for anyone interested in considering DynamoDB. "Although I’m not thrilled about the additional work we had to do (at times it felt like going back two decades in technology by writing indexes ourselves)," he writes, "we did end up with some nice reusable code to help us with the serialization and indexes and such, which will make future projects easier."

Submitted by SpaceGhost
SpaceGhost (23971) writes "The Washington Post reports that the United States Postal Service has contracted with Wahconah Group, Inc. to produce a line of USPS branded smart clothing. Per USPS Licensing manager Steven Mills “This agreement will put the Postal Service on the cutting edge of functional fashion... The main focus will be to produce Rain Heat & Snow apparel and accessories using technology to create ‘smart apparel’ — also known as wearable electronics.” USPS Spokesman Roy Betts reports that the line will be found in premium department stores and specialty stores starting in 2014. The Washington Post points out that the USPS had done a similar retail line in the 1980s sold exclusively at Post Offices, but the line was discontinued after lobbyists complained of competition with the private sector"

+ - 158 Scientists develop a way to extract energy from coal without burning it ->

Submitted by Time_Ngler
Time_Ngler (564671) writes "Scientists have developed a new method to utilize the power from coal, by having it chemically react with iron-oxide pellets. Working over a span of 10 years with a budget of $15 million, barring any unforeseen problems, the new process should be ready to go into commercial production within the next 5 years. The reaction does not produce carbon dioxide and leaves water and coal ash as its byproducts. Furthermore, the iron used in the reaction can be recycled."

Submitted by sciencehabit
sciencehabit (1205606) writes "During the presidential campaign last fall, a single message was repeated endlessly in Appalachian coal country: President Barack Obama and his Environmental Protection Agency, critics said, had declared a "war on coal" that was shuttering U.S. coal-fired power plants and putting coal miners out of work. Not so, according to a newly-presented analysis of coal plant finances and economics. Instead, coal is losing its battle with other power sources mostly on its merits."

_0x783czar writes "Sony has today announced their next generation console, the Playstation 4. It is slated to have an x86 based AMD chipset, which is why Sony is describing the new console as a "Super Charged PC". They also hope that the x86 architecture will make it easier for developers to create games, since they will be able to write the code for the same architecture as a PC. No pictures have yet been released to show what this new console will look like, aside from the the controller: which will have a touch-pad and & camera tracked light. This new console will also focus heavily on social interaction and aims to provide an easy way to pause and share video of your last few minutes of gameplay. In addition to this, it is reported to also have the ability to let your friends remotely control your character in game so as to help you get through a difficult spot; or even just to watch as spectators. Sony hopes to have this new console compete with the Wii U and the upcoming XBox 720 (name pending), but many people are still skeptical since no actual pictures of the console have been released. "Pics or it didn't happen.""

Submitted by sc30317
sc30317 (2594629) writes "Dear Slashdotters, I am in a bit of an unusual conundrum; my house got robbed on Friday, and all of our electronics got stolen. Everything. Now, I have to go out and buy all new electronics with the insurance money. We had 5 TVs (don't ask), 3 Laptops, a Bose Sound dock with iPod, a digital camera and a Desktop stolen. It's looking like I am going to get around $10K from the insurance company to replace everything. What would you do if you had to replace ALL of your technology in your house at once?
I'm thinking:

* Replace TVs
* Nice Desktop
* New speakers
* New, cool stuff I don't know about (suggestions welcome)

I already added a DVR security system, so hopefully the new things won't get burgled! Looking for suggestions to utilize my money in order to get the best stuff. Also, no windows computers allowed in my house [because this IS slashdot, after all]

Thanks,
sc30317"

Submitted by Copper Nikus
Copper Nikus (1615089) writes "An article at the BBC makes a shocking claim about mosquitoes. It appears some individual insects in the wild have developed the ability to ignore the very popular DEET repelent after a first exposure. Imagine what misery this will bring to the human race if this trait spreads to the general mosquito population through the process of evolution through natural selection (or through divine intervention if you happen to be a creationist)."

Nerval's Lobster writes "The Recording Industry Association of America (RIAA) claims that Google has failed in its attempt to lower the search-results rankings of so-called “pirate” Websites. “We have found no evidence that Google’s policy has had a demonstrable impact on demoting sites with large amounts of piracy,” read the report’s summary (PDF). “These sites consistently appear at the top of Google’s search results for popular songs or artists.” Last August, Google indicated that it would start lowering the search-result rankings of Websites with high numbers of “valid” copyright removal notices. “This ranking change should help users find legitimate, quality sources of content more easily—whether it’s a song previewed on NPR’s music website, a TV show on Hulu or new music streamed on Spotify,” Amit Singhal, Google’s senior vice president of Engineering, wrote in a corporate blog posting at the time. Google, which receives millions of copyright removal notices every month, also offers a counter-notice tool for those who believe their Websites have been unfairly targeted for copyright violations."

Submitted by alphadogg
alphadogg (971356) writes "Microsoft Azure's cloud outperformed Amazon Web Services in a series of rigorous tests conducted by Nasuni, a storage vendor that annually benchmarks cloud service providers (CSPs). Nasuni uses public cloud resources in its enterprise storage offering, so each year the company conducts a series of rigorous tests on the top CSPs' clouds in an effort to see which companies offer the best performing, most reliable infrastructure. Last year, Amazon Web Services' cloud came out on top, but this year Microsoft Azure outperformed AWS in performance and reliability measures. AWS is still better at handling extra-large storage volumes, while Nasuni found that the two OpenStack powered clouds it tested — from HP and Rackspace — were lacking, particularly at larger scales."

Submitted by Anonymous Coward
An anonymous reader writes "A White House petition to make unlocking cell phones legal again has passed the 100,000 signature mark. Passing the milestone means the US government has to issue an official response. On January 26th, unlocking a cell phone that is under contract became illegal in the U.S. Just before that went into effect, a petition was started at whitehouse.gov to have the Librarian of Congress revisit that decision. "It reduces consumer choice, and decreases the resale value of devices that consumers have paid for in full. The Librarian noted that carriers are offering more unlocked phones at present, but the great majority of phones sold are still locked.""

But the ruling also stated that if it is password protected, then the police need a warrant. Previous to this case there was no decision on if the police could search your phone without a warrant in Canada."

+ - 171 New process that takes the energy from coal without burning it->

Submitted by
rtoz
rtoz writes "Ohio State students had come up with a scaled-down version of a power plant combustion system with a unique experimental design--one that chemically converts coal to heat while capturing 99 percent of the carbon dioxide produced in the reaction.

Typical coal-fired power plants burn coal to heat water to make steam, which turns the turbines that produce electricity. In chemical looping, the coal isn't burned with fire, but instead chemically combusted in a sealed chamber so that it doesn't pollute the air.

This new technology, called coal-direct chemical looping, was pioneered by Liang-Shih Fan, professor of chemical and biomolecular engineering and director of Ohio State's Clean Coal Research Laboratory"

Submitted by cylonlover
cylonlover (1921924) writes "If Joseph Zawodny, a senior scientist at NASA’s Langley Research Center, is correct, the future of energy may lie in a nuclear reactor small enough and safe enough to be installed where the home water heater once sat. Using weak nuclear forces that turn nickel and hydrogen into a new source of atomic energy, the process offers a light, portable means of producing tremendous amounts of energy for the amount of fuel used. It could conceivably power homes, revolutionize transportation and even clean the environment."
