mask.of.sanity writes Forensics and industry experts have cast doubt on an alleged National Security Agency capability to locate whistle blowers appearing in televised interviews based on how the captured background hum of electrical devices affects energy grids. Divining information from electrified wires is a known technique: Network Frequency Analysis (ENF) is used to prove video and audio streams have not been tampered with, but experts weren't sure if the technology could be used to locate individuals.

This is an interview with Duolingo engineer Franklin Ditzler. He's not a smooth marketing guy getting all rah-rah about the company and what it does, just a coder who enjoys his job and seems to like where he works and what he's doing. Note that Duolingo is a free language teaching tool, and they seem determined to keep it free for language students by selling crowdsourced translation services to companies like CNN and BuzzFeed.

Duolingo founder and CEO Luis von Ahn is an associate professor in the Carnegie Mellon University Computer Science Department, and was one of the original developers behind reCAPTCHA. Google acquired ReCAPTCHA in 2009 for "an undisclosed sum," a bit of history that led TechCrunch to speculate back in 2011 that Google would buy Duolingo within six months -- which didn't happen. But don't despair. It's still possible that Google (or another big company) might absorb Duolingo. We'll just have to wait and see -- and possibly improve our foreign language skills while we wait.

realized (2472730) writes "In nine cases in 2013, state police were unable to break the encryption used by criminal suspects they were investigating, according to an annual report on law enforcement eavesdropping released by the U.S. court system on Wednesday. That's more than twice as many cases as in 2012, when police said that they'd been stymied by crypto in four cases—and that was the first year they'd ever reported encryption preventing them from successfully surveilling a criminal suspect. Before then, the number stood at zero."

New submitter DaveSmith1982 writes with word from PV Tech that A property tax exemption for solar power systems in California has been extended to 2025, following the passing of a bill as part of the annual state budget. Senate Bill 871 (SB871) was approved during the signing of the budget by governor Jerry Brown, which took place last week. The wording of SB871 extends the period during which property taxes will not be applied to "active solar energy systems," which includes PV and solar water heaters.

New submitter marxmarv writes If you search the web for communications security information, or read online tech publications like Linux Journal or BoingBoing, you might be a terrorist. The German publication Das Erste disclosed a crumb of alleged XKeyScore configuration, with the vague suggestion of more source code to come, showing that Tor directory servers and their users, and as usual the interested and their neighbor's dogs due to overcapture, were flagged for closer monitoring. Linux Journal, whose domain is part of a listed selector, has a few choice words on their coveted award. Would it be irresponsible not to speculate further?

Graculus (3653645) writes Budgetmakers in the U.S. Senate have moved to halt U.S. participation in ITER, the huge international fusion experiment now under construction in Cadarache, France, that aims to demonstrate that nuclear fusion could be a viable source of energy. Although the details are not available, Senate sources confirm a report by Physics Today that the Senate's version of the budget for the Department of Energy (DOE) for fiscal year 2015, which begins 1 October, would provide just $75 million for the United States' part of the project. That would be half of what the White House had requested and just enough to wind down U.S. involvement in ITER. According to this story from April, the U.S. share of the ITER budget has jumped to "$3.9 billion — roughly four times as much as originally estimated." (That's a pretty big chunk; compare it, say, to NASA's entire annual budget.)

redletterdave (2493036) writes Facebook chief operating officer Sheryl Sandberg said the company's experiment designed to purposefully manipulate the emotions of its users was communicated "poorly". Sandberg's public comments, which were the first from any Facebook executive following the discovery of the one-week psychological study, were made while attending a meeting with small businesses in India that advertise on Facebook. "This was part of ongoing research companies do to test different products, and that was what it was," Sandberg said. "It was poorly communicated. And for that communication we apologize. We never meant to upset you." anavictoriasaavedra points out this article that questions how much of this outrage over an old press release is justified and what's lead to the media frenzy. Sometimes editors at media outlets get a little panicked when there's a big story swirling around and they haven't done anything with it. It all started as a largely ignored paper about the number of positive and negative words people use in Facebook posts. Now it's a major scandal. The New York Times connected the Facebook experiment to suicides. The story was headlined, Should Facebook Manipulate Users, and it rests on the questionable assumption that such manipulation has happened. Stories that ran over the weekend raised serious questions about the lack of informed consent used in the experiment, which was done by researchers at Cornell and Facebook and published in the Proceedings of the National Academy of Sciences. But to say Facebook’s slight alteration of news feeds caused people to suffer depression seems to be unsupported by any kind of data or logic.

mdsolar writes with news about the cleanup of the site that exposed Harold McCluskey to the highest dose of radiation from americium ever recorded. Workers are finally preparing to enter one of the most dangerous rooms in the world — the site of a 1976 blast in the United States that exposed a technician to a massive dose of radiation and led to his nickname: the "Atomic Man." Harold McCluskey, then 64, was working in the room at the Hanford Nuclear Reservation when a chemical reaction caused a glass glove box to explode. He was exposed to the highest dose of radiation from the chemical element americium ever recorded — 500 times the occupational standard. Hanford, located in central Washington state, made plutonium for nuclear weapons for decades. The room was used to recover radioactive americium, a byproduct of plutonium. Covered with blood, McCluskey was dragged from the room and put into an ambulance headed for the decontamination center. Because he was too hot to handle, he was removed by remote control and transported to a steel-and-concrete isolation tank. During the next five months, doctors laboriously extracted tiny bits of glass and razor-sharp pieces of metal embedded in his skin. Nurses scrubbed him down three times a day and shaved every inch of his body every day. The radioactive bathwater and thousands of towels became nuclear waste.

Zothecula writes Rising atmospheric CO2 levels can generally be tackled in three ways: developing alternative energy sources with lower emissions; carbon capture and storage (CCS); and capturing carbon and repurposing it. Researchers at Princeton University are claiming to have developed a technique that ticks two of these three boxes by using solar power to convert CO2 into formic acid. With power from a commercially available solar panel provided by utility company Public Service Electric and Gas (PSE&G), researchers in the laboratory of Princeton professor of chemistry Andrew Bocarsly, working with researchers at New Jersey-based start-up Liquid Light Inc., converted CO2 and water to formic acid (HCOOH) in an electrochemical cell.
