US Successfully Tests Self-Steering Bullets

mpicpp sends this report from The Independent: The United States Department of Defense has carried out what it says is its most successful test yet of a bullet that can steer itself towards moving targets. Experienced testers have used the technology to hit targets that were actively evading the shot, and even novices that were using the system for the first time were able to hit moving targets. The project, which is known as Extreme Accuracy Tasked Ordnance weapon, or Exacto, is being made for the American government’s military research agency, DARPA. It is thought to use small fins that shoot out of the bullet and re-direct its path, but the U.S. has not disclosed how it works. Technology in the bullet allows it to compensate for weather and wind, as well as the movement of people it is being fired at, and curve itself in the air as it heads towards its target.

New Privacy Threat: Automated Vehicle Occupancy Detection

An anonymous reader writes: The Electronic Frontier Foundation is warning against a new potential privacy threat: cameras that look inside cars and try to identify how many people are inside. This technology is a natural combination of simpler ones that have existed for years: basic object recognition software and road-side cameras (red light cameras, speeding cameras, license plate readers — you name it). Of course, we can extrapolate just a bit further, and point out that as soon as the cameras have high enough resolution, they can start running face recognition algorithms on the images, and determine the identities of a vehicle’s occupants. “The San Diego Association of Governments (SANDAG), a government umbrella group that develops transportation and public safety initiatives across the San Diego County region, estimates that 15% of drivers in High Occupancy Vehicle (HOV) lanes aren’t supposed to be there. After coming up short with earlier experimental projects, the agency is now testing a brand new technology to crack down on carpool-lane scofflaws on the I-15 freeway. … In short: the technology is looking at your image, the image of the people you’re with, your location, and your license plate. (SANDAG told CBS the systems will not be storing license plate data during the trial phase and the system will, at least for now, automatically redact images of drivers and passengers. Xerox’s software, however, allows police the option of using a weaker form of redaction that can be reversed on request.)” Read more of this story at Slashdot.

Pandora Paying Artists $0.0001 More Per Stream Than It Was Last Year

journovampire writes: Pandora has revealed that it’s paying a 10, 000th of a dollar more to music labels and artists than it was in 2014. From the article: “Pandora has revealed that its royalty payments to SoundExchange, the US licensing body which collects performance royalties on behalf of record labels and artists, have just increased by 8%. The news was confirmed in a call with investors following Pandora’s Q1 fiscal results announcement on Thursday (April 23), in which it posted a three-month net loss of $48.3m. In what Pandora CEO Brian McAndrews called a scheduled annual step-up, Pandora has from January 1 been paying out an average $0.0014 per ad-funded stream and $0.0024 per premium stream to SoundExchange.” 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.

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.

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.

Whoah, Small Spender! Steam Sets Limits For Users Who Spend Less Than $5

As GameSpot reports, Valve has implemented a policy that reduces the privileges of Steam users unless those users have spent $5 through the service. Along the same lines as suggestions to limit spam by imposing a small fee on emails, the move is intended to reduce resource abuse as a business model. From the article: “Malicious users often operate in the community on accounts which have not spent any money, reducing the individual risk of performing the actions they do, ” Valve said. “One of the best pieces of information we can compare between regular users and malicious users are their spending habits as typically the accounts being used have no investment in their longevity. Due to this being a common scenario we have decided to restrict certain community features until an account has met or exceeded $5.00 USD in Steam.” Restricted actions include sending invites, opening group chats, and taking part in the Steam marketplace.

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.
