angry tapir writes "Smartphones that support NFC have been making their way onto the market, but many handsets still don't support the wireless technology. As an alternative, Microsoft researchers have prototyped a system that instead uses a phone's microphone and speaker to transmit and receive data. The P2P data transfer system uses a novel technique of 'self-jamming' to stop nefarious third parties from monitoring transfers, and the researchers believe it's more secure than standard NFC communications. No word on whether it sounds like the squeal of a 56k modem."

MrAndrews writes "After reading a Slashdot story about adblocking and the lively discussion that followed, I got to wondering how else sites can support themselves, if paywalls and ads are both non-starters. Microtransactions have been floated for years, but never seem to take off, possibly because they come off as arbitrary taxation or cumbersome walled-garden novelties. Still, it seems like the idea of microtransactions is still appealing, it's just the wrapping that's always been flawed. I wanted to know how viable the concept really was, so I've created a little experiment to gather some data, to put some real numbers to it. It's a purely voluntary system, where you click 1, 2 or 3-cent links in your bookmark bar, depending on how much you value the page you're visiting. No actual money is involved, it's just theoretical. There's a summary page that tells you how much you would have spent, and I'll be releasing anonymized analyses of the data in the coming weeks. If you're game, please check out the experiment page for more information, and give it a go. Even if you only use it once and forget about it, that says something about the concept right there."

lcam writes "A Richard Stallman opinion piece appears at Reuters addressing the 'Too big to fail' view that has recently caused large corporations to be bailed out by taxpayer dollars. His solution is elegant: 'We tax a company’s gross income, with a tax rate that increases as the company gets bigger. Companies would be able to reduce their tax rates by splitting themselves up.' However, it could use some refining. For example, his measure would create a required minimum 'Return on Investment' scale that corporations need to follow to be viable, and these types of metrics are very industry specific. Another issue is that many large corporations stay in business because they don't take unnecessary risk. Companies like Intel, Lockheed, Walmart are very large and have a very low chance of failure, yet Stallman would have them split up as a result of the excessive risks that banks and insurance companies were seen to have taken. It also has the potential to cause problems with the global market; some multinationals may find it better to simply 'move out' to a country that doesn't compromise their business models. How can this idea be made better?"

Tator Tot writes "Grape pomace, the mashed up skins and stems left over from making wine and grape juice, could serve as a good starting point for ethanol production, according to a new study (from the Journal of Agriculture and Food Chemistry). Due to growing interest in biofuels, researchers have started looking for cheap and environmentally sustainable ways to produce such fuels, especially ethanol. Biological engineer Jean VanderGheynst at the University of California, Davis, turned to grape pomace, because winemakers in California alone produce over 100,000 tons of the fruit scraps each year, with much of it going to waste."

An anonymous reader writes "Cyberdyne announced today an improved version of the HAL (Hybrid Assistive Limb) robotic exoskeleton at the Japan Robot Show. From the article: 'he latest version of the HAL has remained brain-controlled but evolved to a full body robot suit that protects against heavy radiation without feeling the weight of the suit. Eventually it could be used by workers dismantling the crippled Fukushima nuclear plant."

another random user writes with this news from Ars Technica:"More than three-quarters of the digital coins in the Bitcoin digital currency scheme aren't circulating because they remain dormant in user accounts that have never participated in outgoing transactions, a recently published study has found. The figure translates to more than 7.019 million BTCs, the term used to denote a single coin under the digital currency, which uses strong cryptography and peer-to-peer networking to enable anonymous payments among parties who don't necessarily know or trust each other. Based on exchange rates listed on Mt.Gox — the most widely used Bitcoin exchange — the coins have a value of more than $82.87 million. On May 13, the date the researchers analyzed their data, there were slightly more than 9 million BTCs in existence."

ideonexus writes "While the decision has been a footnote in most news stories, the Washington Post is raising the question of what it means that Google can shut down access to the anti-Islam film in countries where that film has sparked riots, something the American government cannot do thanks to our First Amendment. A popular meme in the Information Age is that the Internet spreads democracy by enabling citizens to organize and speak out, but we forget that much of that speech is now hosted by third parties who are under no obligation to protect it."

pigrabbitbear writes "Anti-drug squads are now using Brazilian spy drones to sniff out drug labs that dot Bolivia in increasing numbers. Felipe Caceras, Bolivia's top anti-drug official, claims that some 240 drug labs have been busted in Santa Cruz, an eastern lowlands state bordering Brazil, this month alone, all thanks to Brazil's drones."

ericjones12398 writes "The effectiveness of television, as an advertising medium and as a return on investment (ROI), has been constantly questioned since the arrival of the 'digital marketing age.' Not surprisingly, those who are loudest with this concern are mainly high-tech technology companies that are either strong proponents of online advertising — like Google — and/or device hardware manufacturers — like Apple. These organizations hope to 'improve the user experience' by introducing proprietary technologies — usually their own — that can integrate within the existing television environment."

Sparrowvsrevolution writes "In the wake of confirmation that the U.S. government was involved in the creation of Stuxnet and likely Flame, a look over job listings on defense contractor sites shows just how explicitly the Pentagon and the firms that service it are recruiting offense-oriented hackers. Northrop Grumman, Raytheon, Lockheed Martin, SAIC, and Booz Allen have all posted job ads that require skills like 'exploit development,' have titles like 'Windows Attack Developer,' or asks them to 'plan, execute, and assess an Offensive Cyberspace Operation.'"

Hugh Pickens writes "The UC Berkeley News Center reports that a prestigious group of 22 internationally known scientists from around the world is warning that population growth, widespread destruction of natural ecosystems, and climate change may be driving Earth toward an irreversible change in the biosphere, a planet-wide tipping point that would have destructive consequences absent adequate preparation and mitigation. 'It really will be a new world, biologically, at that point,' warns lead author Anthony Barnosky. 'The data suggests that there will be a reduction in biodiversity and severe impacts on much of what we depend on to sustain our quality of life, including, for example, fisheries, agriculture, forest products and clean water. This could happen within just a few generations.' The authors note that studies of small-scale ecosystems show that once 50-90 percent of an area has been altered, the entire ecosystem tips irreversibly into a state far different from the original, in terms of the mix of plant and animal species and their interactions. Humans have already converted about 43 percent of the ice-free land surface of the planet to uses like raising crops and livestock and building cities. This situation typically is accompanied by species extinctions and a loss of biodiversity. 'My view is that humanity is at a crossroads now, where we have to make an active choice,' says Barnosky. 'One choice is to acknowledge these issues and potential consequences and try to guide the future (in a way we want to). The other choice is just to throw up our hands and say, 'Let's just go on as usual and see what happens.'"

nk497 writes "Mozilla has accused Microsoft of trying to go back to the 'digital dark ages' by limiting rival browsers in the ARM version of Windows 8. Third-party browsers won't work in the desktop mode, and Metro style browsers will be limited in what APIs they can use, said Mozilla general counsel Harvey Anderson, forcing users to move to IE instead. Mozilla said it was the first step toward a new platform lock-in that 'restricts user choice, reduces competition and chills innovation,' and pointed out that such browser control was exactly what upset EU and U.S. regulators about IE in the first place. Anderson called on Microsoft to 'reject the temptation to pursue a closed path,' adding 'the world doesn't need another closed proprietary environment.'"

An anonymous reader writes "Catching a flight in the U.S. isn't a great experience anymore due to the security checks involved. You have to remove your shoes, your belt, get your laptop out, be scanned and subjected to radiation in the process. Hundreds of other people are doing the same thing, meaning it takes 40 minutes instead of four. Now, the TSA has come up with a clever, money-making alternative. Instead of scaling back security or speeding it up, you can instead pay $100 and bypass it completely!"
