Advances In Cinema Tech Overcoming a Strange Racial Divide 164

barlevg writes "Since the birth of film, shooting subjects of darker complexion has been a technical challenge: light meters, film emulsions, tone and color models, and the dynamic range of the film itself were all calibrated for light skin, resulting in dark skin appearing ashy and washed-out. Historically, filmmakers have used workarounds involving "a variety of gels, scrims and filters." But now we live in the age of digital filmmaking, and as film critic Ann Hornaday describes in the Washington Post, and as is showcased in recent films such as "12 Years a Slave," "Mother of George" and "Black Nativity," a collection of innovators have set to work developing techniques in lighting, shooting and post-processing designed to counteract century-old technological biases as old as the medium itself."

Researchers Show How Easy It Is To Manipulate Online Opinions 115

jcatcw writes "A recent study shows that a single random up-vote, randomly chosen, created a herding behavior in ratings that resulted in a 25% increase in the ratings but the negative manipulation had no effect. An intuitive explanation for this asymmetry is that we tend to go along with the positive opinions of others, but we tend to be skeptical of the negative opinions of others, and so we go in and correct what we think is an injustice. The third major result was that these effects varied by topic. So in business and society, culture, politics, we found substantial susceptibility to positive herding, whereas in general news, economics, IT, we found no such herding effects in the positive or negative direction."

Money is supposed to represent a store of value earned by an economy's participants.

Only in the mind of people who understand neither the origin nor general use of money. Money has historically been used successfully for trade and taxing.

Meanwhile, all attempts at trying to turn money into a storage of value has has had dire consequences. The Euro simply being the latest in a bunch of total failures by people who are macro-economically illiterate.

The second safest road is where everybody is moving at approximately the same speed with adequate spacing in between them.

Traffic death stats here in Sweden (from 2011) tells a far different story.

* 33% solo car
* 24% meeting cars
* 18% slow moving objects (animals/pedestrians/animals)
* 11% interesections/etc
* 9% other
* 3% cars moving in same direction under normal circumstances.

For Overstated Claims, Gore, Tesla Upbraided By NWS, NHTSA Respectively 195

barlevg writes "In a recent interview, former Vice President and environmental activist Al Gore made a bold claim, that man-made global warming was causing hurricanes to be formed of such severity that 'they're adding a 6' to the hurricane scale, going on to say that 'The fingerprint of man-made global warming is all over these storms and extreme weather events.' In response, the National Weather Service has responded that they have no plans to add a 'doomsday Category 6' to their rating scale: 'No, we're not pursuing any such change. I'm also not sure who VP Gore means by "they,"' also noting that 'Category 5 has no ceiling: it includes hurricanes with top sustained winds of 157 mph and higher.' Furthermore, a recently leaked United Nations climate assessment claims only 'low confidence' of a link between human activity and increased hurricane severity and that this is likely due to increased human settlement in coastal areas and other regions vulnerable to natural disasters." Along similar lines, the National Highway Traffic Safety Administration says that Tesla's Model S, no matter how safe it is, doesn't get any special grade inflation: there's no "5.4" score (as the company did in a press release this week), because that's just not how the NHTSA keeps score.

In 2013, energy was 4 times cheaper in the United States than in Europe, and 6 times cheaper than in Germany.

Using current EUR/USD conversion rates and cents/KWh

Industry Retail Nov 2012 (including taxes):
* Germany: 15
* US Avg: 6.53

Residential Retail Nov 2012 (including taxes):
* Germany: 35
* US Avg: 11.74

If you wander why the German residential electricity is so high, it is because they pay a massive 20.50 EUR/MWh or 27 cents/KWh in taxes.

Seriously, nowhere have I been able to find the how electricity would be 6 times more expensive in Germany than in the US, even with taxes applied the difference is only 2.5-3 times. Without taxes, it is less than 2 times.

Microsoft: Xbox One Won't Require Kinect To Function 216

UnknowingFool writes "Microsoft has reversed course on another aspect of the Xbox One. Though Xbox One will come bundled with a Kinect sensor, the console will work without it. Critics were had suggested that an always-on video and audio sensor could be used to spy on users. Microsoft's Marc Whitten said, 'Games use Kinect in a variety of amazing ways from adding voice to control your squad mates to adding lean and other simple controls beyond the controller to full immersive gameplay. That said, like online, the console will still function if Kinect isn't plugged in, although you won't be able to use any feature or experience that explicitly uses the sensor.' This is the latest reversal from Microsoft since they killed the phone-home DRM and made it region-free."

The Science of 12-Step Programs 330

Hugh Pickens DOT Com writes "Since the inception of Alcoholics Anonymous — the progenitor of 12-step programs — science has sometimes been at odds with the notion that laypeople can cure themselves because the numerous spiritual references that go with the 12-step program puts A.A. on "the fringe" in the minds of many scientists. But there is an interesting read at National Geographic where Jarret Liotta writes that new research shows that the success of the 12-step approach may ultimately be explained through medical science and psychology. According to Marvin Seppala, chief medical officer at Hazelden and sober 37 years, attending 12-step meetings does more than give an addict warm, fuzzy feelings. The unconscious neurological pull of addiction undermines healthy survival drives, causing individuals to make disastrous choices, he says. "People will regularly risk their lives—risk everything—to continue use of a substance." Addicts don't want to engage in these behaviors, but they can't control themselves. "The only way to truly treat it is with something more powerful," like the 12 steps, that can change patterns in the brain. Philip Flores, author of Addiction as an Attachment Disorder, says the human need for social interaction is a physiological one, linked to the well-being of the nervous system. When someone becomes addicted, Flores says, mechanisms for healthy attachment are "hijacked," resulting in dependence on addictive substances or behaviors. Some believe that addicts, even before their disease kicks in, struggle with knowing how to form emotional bonds that connect them to other people. Co-occurring disorders, such as depression and anxiety, make it even harder to build those essential emotional attachments. "We, as social mammals, cannot regulate our central nervous systems by ourselves," Flores says. "We need other people to do that.""

Bacteria Behaviour Can Shed Light On How Financial Markets Work 91

notscientific writes "Bacteria invest in proteins in an attempt to reduce stress or increase energy intake, while humans invest in cash. In both cases, better tradeoffs pay off. The similarities in tradeoffs faced by both bacteria and humans during investment are actually quite similar. Now, using synthetic biology, a group of scientists has shown that the outcomes of investment decisions in bacteria can be precisely defined, alluding to the idea that human investment activities, such as financial markets, can be thoroughly understood as well, and even modelled."

Have eBooks Peaked? 323

An anonymous reader writes "At Rough Type, Nicholas Carr examines the surprisingly sharp drop in the growth rate for e-book sales. In the U.S., the biggest e-book market, annual sales growth dropped to just 5% in the first quarter of this year, according to the Association of American Publishers, while the worldwide e-book market actually shrank slightly, according to Nielsen. E-books now account for about 25% of total U.S. book sales — still a long way from the dominance most people expected. Carr speculates about various reasons e-books may be losing steam. He wonders in particular about 'the possible link between the decline in dedicated e-readers (as multitasking tablets take over) and the softening of e-book sales. Are tablets less conducive to book buying and reading than e-readers were?' He suggests that the e-book may end up playing a role more like the audiobook — a complement to printed books rather than a replacement."

Campaign To Kill CAPTCHA Kicks Off 558

Bismillah writes "CAPTCHA may be popular with webmasters and others running different sites, but it's a source of annoyance to blind and partially sighted people — and dyslexic people and older ones — who often end up being locked out of important websites as they can't read wonky, obfuscated letters any more than spambots can. A campaign in Australia has started to rid sites of CAPTCHA to improve accessibility for everyone."
