Liquid Mercury Found Under Mexican Pyramid

An anonymous reader writes: An archaeologist has discovered liquid mercury at the end of a tunnel beneath a Mexican pyramid, a finding that could suggest the existence of a king’s tomb or a ritual chamber far below one of the most ancient cities of the Americas. Mexican researcher Sergio Gómez … has spent six years slowly excavating the tunnel, which was unsealed in 2003 after 1, 800 years. Last November, Gómez and a team announced they had found three chambers at the tunnel’s 300ft end, almost 60ft below the the temple. Near the entrance of the chambers, they a found trove of strange artifacts: jade statues, jaguar remains, a box filled with carved shells and rubber balls. Read more of this story at Slashdot.

Tesla To Announce Battery-Based Energy Storage For Homes

Okian Warrior writes: Billionaire Elon Musk will announce next week that Tesla will begin offering battery-based energy storage for residential and commercial customers. The batteries power up overnight when energy companies typically charge less for electricity, then are used during the day to power a home. In a pilot project, Tesla has already begun offering home batteries to SolarCity (SCTY) customers, a solar power company for which Musk serves as chairman. Currently 330 U.S. households are running on Tesla’s batteries in California. The batteries start at about $13, 000, though California’s Pacific Gas and Electric Co. (PCG) offers customers a 50% rebate. The batteries are three-feet high by 2.5-feet wide, and need to be installed at least a foot and a half off the ground. They can be controlled with a Web app and a smartphone app. Read more of this story at Slashdot.

New Privacy Concerns About US Program That Can Track Snail Mail

Lashdots writes: A lawyers’ group has called for greater oversight of a government program that gives state and federal law enforcement officials access to metadata from private communications for criminal investigations and national security purposes. But it’s not digital: this warrantless surveillance is conducted on regular mail. “The mail cover has been in use, in some form, since the 1800s, ” Chief Postal Inspector Guy J. Cottrell told Congress in November. The program targets a range of criminal activity including fraud, pornography, and terrorism, but, he said, “today, the most common use of this tool is related to investigations to rid the mail of illegal drugs and illegal drug proceeds.” Recent revelations that the U.S. Postal Service photographs the front and back of all mail sent through the U.S., ostensibly for sorting purposes, has, Fast Company reports, brought new scrutiny—and new legal responses—to this obscure program.

Music Industry Argues Works Entering Public Domain Are Not In Public Interest

An anonymous reader writes: With news that Canada intends to extend the term of copyright for sound recordings and performers, the recording industry is now pushing the change by arguing that works entering the public domain is not in the public interest. It is hard to see how anyone can credibly claim that works are “lost” to the public domain and that the public interest in not served by increased public access, but if anyone would make the claim, it would be the recording industry.

Africa E-Waste Dump Continues Hyperbole War

retroworks writes: Two stories appear today which feature close up photos of young African men surrounded by scrap metal in the city of Accra. The headlines state that this is where our computers go to die (Wired). The Daily Mail puts it in even starker terms, alleging “millions of tons” are dumped in Agbogbloshie. The stories appear the same day as a press release by investigators who returned this week from 3 weeks at the site. The release claims that Agbogbloshie’s depiction as the worlds “largest ewaste dump site” to be a hoax. It is a scrap automobile yard which accounts for nothing more than local scrap from Accra. Three Dagbani language speaking electronics technicians, three reporters, Ghana customs officials and yours truly visited the site, interviewed workers about the origins of the material, and assessed volumes. About 27 young men burn wire, mostly from automobile scrap harnesses. The electronics — 20 to 50 items per day — are collected from Accra businesses and households. The majority of Accra (population 5M) have had televisions since the 1990s, according to World Bank metadata (over 80% by 2003). The investigation did confirm that most of the scrap was originally imported used, and that work conditions were poor. However, the equipment being recycled had been repaired and maintained, typically for a decade (longer than the original OECD owner). It is a fact that used goods will, one day, eventually become e-waste. Does that support a ban on the trade in used goods to Africa? Or, as the World Bank reports, is the affordable used product essential to establish a critical mass of users so that investment in highways, phone towers, and internet cable can find necessary consumers?

Networking Library Bug Breaks HTTPS In ~1,500 iOS Apps

mrflash818 writes: A new report from analytics service SourceDNA found that roughly 1, 500 iOS apps (with about 2 million total installs) contain a vulnerability that cripples HTTPS and makes man-in-the-middle attacks against those apps easy to pull off. “The weakness is the result of a bug in an older version of the AFNetworking, an open-source code library that allows developers to drop networking capabilities into their apps. Although AFNetworking maintainers fixed the flaw three weeks ago with the release of version 2.5.2, at least 1, 500 iOS apps remain vulnerable because they still use version 2.5.1. That version became available in January and introduced the HTTPS-crippling flaw.” Read more of this story at Slashdot.

Futures Trader Arrested For Causing 2010 ‘Flash Crash’

New submitter dfsmith writes: Apparently the “Flash Crash” of the stock market in May 2010 was perpetrated by a futures trader in the UK. The US Justice Department alleges that he used a “dynamic layering scheme” of large-volume sell orders to confuse other buyers, hence winning big in his futures trades. “By allegedly placing multiple, simultaneous, large-volume sell orders at different price points—a technique known as ‘layering’—Sarao created the appearance of substantial supply in the market. As part of the scheme, Sarao allegedly modified these orders frequently so that they remained close to the market price, and typically canceled the orders without executing them. When prices fell as a result of this activity, Sarao allegedly sold futures contracts only to buy them back at a lower price. Conversely, when the market moved back upward as the market activity ceased, Sarao allegedly bought contracts only to sell them at a higher price.” Read more of this story at Slashdot.

Old Marconi Patent Inspires Tiny New Gigahertz Antenna

agent elevator writes Gehan Amaratunga and a group of engineers in England noted that the Guglielmo Marconi’s famous British patent application from 1900 had an interesting and little noticed detail. It depicted a transmitter linked to an antenna connected to a coil, which had one end dangling while the RF signal was fed to the middle of the coil. That detail inspired them to develop a way to reduce the size of a GHz antenna without significant transmission loss by using dielectrics as the radio wave emitting material instead of conductors.

Utilities Battle Homeowners Over Solar Power

HughPickens.com writes Diane Cardwell reports in the NYT that many utilities are trying desperately to stem the rise of solar power, either by reducing incentives, adding steep fees or effectively pushing home solar companies out of the market. The economic threat has electric companies on edge. Over all, demand for electricity is softening while home solar is rapidly spreading across the country. There are now about 600, 000 installed systems, and the number is expected to reach 3.3 million by 2020, according to the Solar Energy Industries Association. In Hawaii, the current battle began in 2013, when Hawaiian Electric started barring installations of residential solar systems in certain areas. It was an abrupt move — a panicked one, critics say — made after the utility became alarmed by the technical and financial challenges of all those homes suddenly making their own electricity. “Hawaii is a postcard from the future, ” says Adam Browning, executive director of Vote Solar, a policy and advocacy group based in California. But utilities say that solar-generated electricity flowing out of houses and into a power grid designed to carry it in the other direction has caused unanticipated voltage fluctuations that can overload circuits, burn lines and lead to brownouts or blackouts. “At every different moment, we have to make sure that the amount of power we generate is equal to the amount of energy being used, and if we don’t keep that balance things go unstable, ” says Colton Ching, vice president for energy delivery at Hawaiian Electric, pointing to the illuminated graphs and diagrams tracking energy production from wind and solar farms, as well as coal-fueled generators in the utility’s main control room. But the rooftop systems are “essentially invisible to us, ” says Ching, “because they sit behind a customer’s meter and we don’t have a means to directly measure them.” The utility wants to cut roughly in half the amount it pays customers for solar electricity they send back to the grid. “Hawaii’s case is not isolated, ” says Massoud Amin. “When we push year-on-year 30 to 40 percent growth in this market, with the number of installations doubling, quickly — every two years or so — there’s going to be problems.” Read more of this story at Slashdot.

How Uber Surge Pricing Really Works

minstrelmike writes with this analysis from Nicholas Diakopoulos of the Washington Post: At the core of Uber’s wild success and market valuation of over $41 billion is its data and algorithmically fueled approach to matching supply and demand for cars. It’s classic economics, supposedly….but is Uber’s surge pricing algorithm really doing what they claim? Do surge prices really get more cars on the road? My analysis suggests that rather than motivating a fresh supply of drivers, surge pricing instead re-distributes drivers already on the road. Adds minstrelmike: The writer goes on to analyze 4 weeks of pricing info from 5 areas in D.C. and plotted prices versus wait times. “Price surging can work in any of three ways: by reducing demand for cars (less people want a car for a higher price), by creating new supply (providing an incentive for new drivers to hit the roads), or by shifting supply (drivers) to areas of higher demand.” It moves current drivers from one side of town to the other. It does not put new drivers on the road. It can’t because the prices change every 3-5 minutes.” Read more of this story at Slashdot.
