by lupine (#43642313) Attached to: Why US Mileage Ratings Are So Inaccurate

I think that over a certain speed, fuel economy goes way down.

This is because:
For high velocities drag will vary as the square of velocity. Thus, the resultant power needed to overcome this drag will vary as the cube of velocity. The standard equation for drag is one half the coefficient of drag multiplied by the fluid mass density, the cross sectional area of the specified item, and the square of the velocity.

Windfarm Sickness Spreads By Word of Mouth 482

Posted by Soulskill from the people-who-are-allergic-to-ideas dept.
eldavojohn writes "Just like the many stories surrounding alleged 'Wi-Fi sickness,' research is now showing that windfarm sickness spreads by word of mouth instead of applying universally to windfarms. Areas that had never had any noise or health complaints were suddenly experiencing them after 2009 when anti-wind groups targeted populations surrounding windfarms. From the article, 'Eighteen reviews of the research literature on wind turbines and health published since 2003 had all reached the broad conclusion that there was very little evidence they were directly harmful to health.' While there's unfortunately no way to prove that someone is lying about how they feel, it's likely a mixture of confirmation bias, psychosomatic response, hypochondria, greed and hatred of seeing windmills on the horizon that drives this phenomenon."

Apple Kills a Kickstarter Project - Updated 471

Posted by Soulskill from the there-is-but-one-way dept.
Nerdfest writes "Venturebeat is reporting that a successfully funded Kickstarter project for a portable phone charger that works with both Apple and Android devices has been canceled because Apple wouldn't let the creators license its Lightning connector. Quoting: 'Edison Junior, the technology and design lab behind the POP portable power station, is returning the full $139,170 in funding it received from Kickstarter backers to develop the device. Unfortunately, Apple has refused to give the project permission to license the Lightning charger in a device that includes multiple charging options. ... "We didn’t get a yes or a no up front," Siminoff said. "But as we kept going back and forth it was clear that it was getting harder. Then, when we saw that they weren’t even going to allow a Lightning connector and a 30-pin connector together, we knew it was over." He also said that, while Apple is a private company and can do whatever it wishes, it should watch out. "When you do things that are bad for the customer I think it will be bad for them.”''" Update: 12/21 22:16 GMT by S : Apple has relented. A spokesman for the company told Ars, "Our technical specifications provide clear guidelines for developing accessories and they are available to MFi licensees for free. We support accessories that integrate USB and Lightning connectors, but there were technical issues that prevented accessories from integrating 30-pin and Lightning connectors so our guidelines did not allow this. We have been working to resolve this and have updated our guidelines to allow accessories to integrate both 30-pin and Lightning connectors to support charging."

Facebook Changes Privacy Policies, Scraps User Voting 119

Posted by samzenpus from the read-it-and-weep dept.
Orome1 writes "The voting period for the proposed changes to Facebook's Statement of Rights and Responsibilities and Data Use Policy has ended on Monday, and despite the email sent out to the users asking them to review the changes and cast their vote, less than one percent of all users have done so. 'An external auditor has reviewed and confirmed the final results. Of the 668,872 people who voted, 589,141 recommended we keep our existing SRR and Data Use Policy,' stated Elliot Schrage, Facebook's vice president of communications, public policy, and marketing. Still, that is not nearly enough to prevent the proposed changes — as required by Facebook, at least 30 percent of the users should have voted against them in order to keep the previous versions of the policies. Schrage pointed out that that the whole experience illustrated the clear value of Facebook's notice and comment process."

Advertising May Soon Follow You From One Device To the Next 132

Posted by timothy from the for-that-twilight-zone-feeling dept.
moon_unit2 writes "We're all familiar with ads that seem to follow you around as you go from one website to another. A startup called Drawbridge has developed technology that could let those ads follow you even when you pick up a smartphone or tablet. The company, founded by an ex-Google scientist, employs statistical methods to try to match and identify users on different devices. The idea is that this will preserve privacy while making mobile ads more lucrative, although some experts aren't convinced that the data will be truly anonymous."

Facebook Says EU 'Right To Be Forgotten' Would Harm Privacy 277

Posted by timothy from the want-to-subscribe-to-your-newsletter dept.
judgecorp writes "The European Commission has proposed a "right to be forgotten" online, which would allow users to remove personal data they had shared. The idea has had a lot of criticism, and now Facebook claims it would actually harm privacy. Facebook says the proposal would require social media sites to perform extra tracking to remove data which has been copied to other sites — but privacy advocates say Facebook has misunderstood what the proposal is all about."

Grim Picture of Polar Ice-Sheet Loss 412

Posted by Soulskill from the i-blame-the-ice-cube-miners dept.
ananyo writes "A global team of researchers has come up with the most accurate estimate yet for melting of the polar ice sheets, ending decades of uncertainty about whether the sheets will melt further or actually gain mass in the face of climate change. The ice sheets in Greenland and Antarctica are melting at an ever-quickening pace. Since 1992, they have contributed 11 millimeters — or one-fifth — of the total global sea-level rise, say the researchers. The two polar regions are now losing mass three times faster than they were 20 years ago, with Greenland alone now shedding ice at about five times the rate observed in the early 1990s. This latest estimate, published this week in Science, draws on up to 32 years of ice-sheet simulations and 20 years of satellite data to give an estimate two to three times more accurate than that in the last IPCC report."

Highway To Sell: AC/DC iTunes Snub Finally Over 247

Posted by timothy from the genuine-angus dept.
Hugh Pickens "The LA Times reports that after years of stubbornly arguing that iTunes was, in the words of singer Brian Johnson, 'going to kill music if they're not careful,' AC/DC has reached a deal with Apple to sell its entire catalog — 16 studio albums, four live albums and three compilations — through the service. AC/DC was one of the last high-profile holdouts from the digital music marketplace, outlasting the Beatles, Led Zeppelin, and Pink Floyd, all of which jumped into the realm long after much of the population had accepted the downloading future. Angus Young, AC/DC's lead guitarist (known for wearing a schoolboy's uniform when performing), had long argued against hawking the band's music because he didn't like the idea of allowing for individual song downloads — submitting that the group's albums were designed to be listened to from beginning to end. 'It's like an artist who does a painting,' he said in 2008. 'If he thinks it's a great piece of work, he protects it. It's the same thing: This is our work.'"

Comment Re: Backup Heating (Score 1) 473

I installed a wood burning insert into our fireplace. It has a large glass door so you can still see the flames for ambiance. It is 70% efficient, using a blower to circulate heat and is designed to reignite smoke to reduce particulates. I gather wood locally from trees my neighbors cut down after summer storms.

So I can heat the house in the event of a power outage. I also have an inverter so I can use my prius as a generator to run the blower, router, wifi.

New Credit Card Includes Display and Keypad 118

Posted by samzenpus from the looking-at-plastic dept.
First time accepted submitter pev writes "A new credit card released in Singapore includes a screen and keyboard in order to generate one-time passwords for your online banking. From the article: 'The card has touch-sensitive buttons and the ability to create a "one-time password" - doing away with the need for a separate device sometimes needed to log in to online banking. Future versions of the card could display added information such as the remaining balance.' Lets hope they've put more thought into the implementation than with chip and pin."

Why Would a Mouse Need To Connect To the Internet? 249

Posted by samzenpus from the bring-me-my-bluetooth-spoon dept.
jbrodkin writes "In this hyper-connected, networked world, many more of our devices are getting linked to the cloud, whether we want them to or not. That's sometimes good, and sometimes bad, so when a basic device like a mouse requires a user to go online and set up an account to activate all of its functionality, people are understandably going to ask why? The latest entry in the saga of 'Why the hell does this thing need to connect to the Internet?' comes from Razer, which has caused an uproar by asking users to register gaming mice on the Internet. While it's mainly for syncing settings across devices, gamers are complaining that certain functionality might not be available unless you create an online account for your mouse. Razer has responded to the controversy, but its answers aren't entirely satisfactory."

Will Microsoft Dis-Kinect Freeloading TV Viewers? 478

Posted by samzenpus from the watching-the-watchers dept.
theodp writes "Just when you think the cable TV viewing experience couldn't get any worse, GeekWire reports on the Microsoft Xbox Incubation team's patent-pending Consumer Detector, which uses cameras and sensors like those in the Xbox 360 Kinect controller to monitor, count and in some cases identify the people in a room watching television, movies and other content. Should the number of viewers detected exceed the limits of a particular content license, the system would halt playback unless additional viewing rights were purchased."

Ask Slashdot: Rectifying Nerd Arrogance? 823

Posted by timothy from the wait-for-it-wait-for-it dept.
An anonymous reader writes "Like some Slashdot users, I began attending university last month for computer science. The experience represents my first time away from home and I'm almost constantly with my peers, many of whom are also computer science students. Recently, I have become cognizant of the many negative opinions associated with a 'normal' person's perspective of what a nerd is like. Conversing with my college computer science peers (many of whom are quite nerdy), I have noticed that many of them are extremely arrogant. Upon introspection, I have come to the realization that I am also very similar to them and am very curious, but worried. I have noticed similar personality characteristics on Slashdot. Where does this nerd arrogance come from? How can it be rectified? I am concerned that, if I do not abolish these annoying tendencies, I may have trouble later on in life with my career and relationships. Has anybody run into problems in life with the arrogance that seems to be so prevalent with nerds? If so, how did you handle the situation?"

Seafood Raised on Animal Feces Approved for Consumers 386

Posted by samzenpus from the smells-like-progress dept.
If you are a seafood lover and wish that you could eat more fish raised on pig feces, your dreams are coming true. Due to fierce competition in the Chinese tilapia industry, farmers are increasingly switching to feces instead of commercial feed. From the article: "At Chen Qiang’s tilapia farm in Yangjiang city in China’s Guangdong province, which borders Hong Kong, Chen feeds fish partly with feces from hundreds of pigs and geese. That practice is dangerous for American consumers, says Michael Doyle, director of the University of Georgia’s Center for Food Safety. 'The manure the Chinese use to feed fish is frequently contaminated with microbes like salmonella,' says Doyle, who has studied foodborne diseases in China."
