An anonymous reader writes VideoLAN today launched what is arguably the biggest release of VLC to date: an update for the desktop coordinated with new versions across all major mobile platforms. The world's most-used media player just got a massive cross-platform push. The organization says the releases are the result of more than a year of volunteer work on the VLC engine and the libVLC library. As a result, VLC has gained numerous new features, has seen more than 1,000 bugs fixed, and has significantly increased its scope of supported formats.

UK Scientists Claim 1Tbps Data Speed Via Experimental 5G Technology 71

from the hefty-overages dept.
Mark.JUK writes A team of Scientists working at the University of Surrey in England claim to have achieved, via an experimental lab test, performance of 1Tbps (Terabit per second) over their candidate for a future 5G Mobile Broadband technology. Sadly the specifics of the test are somewhat unclear, although it's claimed that the performance was delivered by using 100MHz of radio spectrum bandwidth over a distance of 100 metres. The team, which forms part of the UK Government's 5G Innovation Centre, is supported by most of the country's major mobile operators as well as BT, Samsung, Fujitsu, Huawei, the BBC and various other big names in telecoms, media and mobile infrastructure. Apparently the plan is to take the technology outside of the lab for testing between 2016 and 2017, which would be followed by a public demo in early 2018. In the meantime 5G solutions are still being developed, with most in the early experimental stages, by various different teams around the world. Few anticipate a commercial deployment happening before 2020 and we're still a long way from even defining the necessary standard.

An Evidence-Based Approach To Online Dating 286

from the if-at-first-you-don't-succeed dept.
HughPickens.com writes Rachel Nuwer writes in the NYT that Dr. Sameer Chaudhry's online dating persona was garnering no response from the women he reached out to so he synthesized 86 literature studies on the subject of online dating in the fields of psychology, sociology, and computer, behavioral, and neurocognitive sciences.in hopes of improving his odds. As it turns out, success begins with picking a user name. While men are drawn to names linked to physical traits (e.g., Cutie), the researchers found, women prefer ones that indicate intelligence (e.g., Cultured). Both sexes respond well to playful names (e.g. Fun2bwith) and shy away from ones with negative connotations (e.g., Bugg). User names that begin with letters from the first half of the alphabet do better than those from the latter half. "As human beings, we have a tendency to give things at the top of a pile more value," says Khan. As for your profile photo, pick a photo with a genuine smile, one that crinkles the eyes, and with a slight head tilt (it's linked to attractiveness). And if you're looking for a male partner, go for that photo of you in siren red—a color that enhances men's attraction to women. "For those attracted to browse into the profile, a description of personal traits increased likeability when it: showed who the dater was and what they were looking for in a 70:30 ratio; stayed close to reality; and employed simple language with humor added. Invitations were most successful in obtaining a response from the potential date when they: were short personalized messages addressing a trait in their profile; rhymed with their screen name or headline message; and extended genuine compliments." And finally, don't wait too long before arranging a face to face meeting.

New Map Shows USA's Quietest Places 99

Posted by samzenpus
from the a-little-peace-and-quiet dept.
sciencehabit writes Based on 1.5 million hours of acoustical monitoring from places as remote as Dinosaur National Monument in Utah and as urban as New York City, scientists have created a map of noise levels across the country on an average summer day. After feeding acoustic data into a computer algorithm, the researchers modeled sound levels across the country including variables such as air and street traffic. Deep blue regions, such as Yellowstone National Park in Wyoming and the Great Sand Dunes National Park in Colorado, have background noise levels lower than 20 decibels — a silence likely as deep as before European colonization, researchers say. That's orders of magnitude quieter than most cities, where noise levels average 50-60 decibels. The National Park Service is using the map to identify places where human-made noise is affecting wildlife.

Smoking Is Even Deadlier Than Previously Thought 365

HughPickens.com writes Who still smokes?" as Denise Grady reports at the NYT that however bad you thought smoking was, it's even worse. A new study has found that in addition to the well-known hazards of lung cancer, artery disease, heart attacks, chronic lung disease and stroke, researchers found that smoking was linked to significantly increased risks of infection, kidney disease, intestinal disease caused by inadequate blood flow, and heart and lung ailments not previously attributed to tobacco. "The smoking epidemic is still ongoing, and there is a need to evaluate how smoking is hurting us as a society, to support clinicians and policy making in public health," says Brian D. Carter, an author of the study. "It's not a done story." Carter says he was inspired to dig deeper into the causes of death in smokers after taking an initial look at data from five large health surveys being conducted by other researchers. As expected, death rates were higher among the smokers but diseases known to be caused by tobacco accounted for only 83 percent of the excess deaths in people who smoked. "I thought, 'Wow, that's really low,' " Mr. Carter said. "We have this huge cohort. Let's get into the weeds, cast a wide net and see what is killing smokers that we don't already know." The researchers found that, compared with people who had never smoked, smokers were about twice as likely to die from infections, kidney disease, respiratory ailments not previously linked to tobacco, and hypertensive heart disease, in which high blood pressure leads to heart failure. "The Surgeon General's report claims 480,000 deaths directly caused by smoking, but we think that is really quite a bit off," concludes Carter adding that the figure may be closer to 540,000.

No single music release features in the Top 100 most-torrented files. From the article: "MBW has analysed TPB’s Top 100 most-pirated files in the 48 hours since its re-emergence. And although you’ll find plenty of movies and a smattering of porn in there, you won’t see a single music release. The Top 4 most-pirated files over the weekend were all movies, led by new Jason Statham vehicle Wild Card. It was followed by three more Hollywood releases – The Interview, American Sniper and Nightcrawler."

Cutting Through Data Science Hype 99

Posted by Soulskill
from the this-year's-silver-bullet dept.
An anonymous reader writes: Data science — or "big data" if you prefer — has evolved into a full-fledged buzzword, thanks to marketing departments around the world. John Foreman writes that part of the marketing blitz has been focused on how fast big data analysis can be. Most companies offering some kind of analytic service try to sell you on how it'll make it easy for you to quickly find and fix the problems with your business. But he points out that good, robust models need a stable set of inputs, and businesses often change far too quickly for any kind of stable prediction. He takes IBM's analytic services as an example, quoting Kevin Hillstrom: "If IBM Watson can find hidden correlations that help your business, then why can't IBM Watson stem a 3 year sales drop at IBM?" Foreman offers some simple advice: "Simple analyses don't require huge models that get blown away when the business changes. ... If your business is currently too chaotic to support a complex model, don't build one."

halfEvilTech writes As part of its 2015 Broadband Progress Report, the Federal Communications Commission has voted to change the definition of broadband by raising the minimum download speeds needed from 4Mbps to 25Mbps, and the minimum upload speed from 1Mbps to 3Mbps, which effectively triples the number of U.S. households without broadband access. Currently, 6.3 percent of U.S. households don't have access to broadband under the previous 4Mpbs/1Mbps threshold, while another 13.1 percent don't have access to broadband under the new 25Mbps downstream threshold.

BarbaraHudson writes Business Insider is reporting that despite billions of sign-ups, almost nobody is publicly active on Google+. Analytics and visualization blogger Kevin Anderson studied data compiled by Edward Morbius, who says that just 9% of Google+'s 2.2 billion users actively post public content. "We've got a grand spanking total of 24 profiles out of 7,875 whose 2015 post activity isn't YouTube comments but Google+ posts. That a 0.3% rate of all profile pages, going back to our 2.2 billion profiles. No wonder Dave Besbris (Google+ boss) doesn't want to talk about numbers," Morbius writes.

Lies, Damn Lies, and Tech Diversity Statistics 335

Posted by timothy
from the facts-are-stubborn-things dept.
theodp writes Some of the world's leading Data Scientists are on the payrolls of Microsoft, Google, Facebook, Yahoo, and Apple. So, it'd be interesting to get their take on the infographics the tech giants have passed off as diversity data disclosures. Microsoft, for example, reported its workforce is 29% female, which isn't great, but if one takes the trouble to run the numbers on a linked EEO-1 filing snippet (PDF), some things look even worse. For example, only 23.35% of its reported white U.S. employee workforce is female (Microsoft, like Google, footnotes that "Gender data are global, ethnicity data are US only"). And while Google and Facebook blame their companies' lack of diversity on the demographics of U.S. computer science grads, CS grad and nationality breakouts were not provided as part of their diversity disclosures. Also, the EEOC notes that EEO-1 numbers reflect "any individual on the payroll of an employer who is an employee for purposes of the employers withholding of Social Security taxes," further muddying the disclosures of companies relying on imported talent, like H-1B visa dependent Facebook. So, were the diversity disclosure mea culpas less about providing meaningful data for analysis, and more about deflecting criticism and convincing lawmakers there's a need for education and immigration legislation (aka Microsoft's National Talent Strategy) that's in tech's interest?

UK Computing Teachers Concerned That Pupils Know More Than Them 388

Posted by timothy
from the at-least-they're-right dept.
mikejuk (1801200) writes A survey of UK schools carried out by Microsoft and Computing at School reveals some worrying statistics that are probably more widely applicable. The survey revealed that (68%) of primary and secondary teachers are concerned that their pupils have a better understanding of computing than they do. Moreover, the pupils reinforced this finding with 47% claiming that their teachers need more training. Again to push the point home, 41% of pupils admitted to regularly helping their teachers with technology. This isn't all due to the teachers being new at the task — 76% had taught computing before the new curriculum was introduced. It seems that switching from an approach that emphasised computer literacy to one that actually wants students to do more difficult things is the reason for the problem.

Google's lead remains overwhelming, with just more than three-quarters of search, according to SatCounter Global Stats. Microsoft's Bing gained some momentum to take 12.5% of the market. Yahoo now has 10.4%. All other search engines combined to take 1.9%.

Box Office 2014: Moviegoing Hits Two-Decade Low 400

mrspoonsi writes The number of people going to the movies in 2014 in North America slipped to its lowest level in two decades. According to preliminary estimates, roughly 1.26 billion consumers purchased cinema tickets between Jan. 1 and Dec. 31. That's the lowest number since 1.21 billion in 1995. Year-over-year, attendance looks to be off 6 percent from 2013, when admissions clocked in at 1.34 billion. Admissions have fluctuated dramatically over the years, and particularly since the advent of modern-day 3D, which can skew the average ticket price. Movie going in North America hit an all-time high in 2002, when 1.57 billion consumers lined up, thanks in part to Spider-Man, The Lord of the Rings: The Two Towers, Star Wars: Episode II — Attack of the Clones, Harry Potter and the Chamber of Secrets and My Big Fat Greek Wedding.

Over 78% of All PHP Installs Are Insecure 112

An anonymous reader writes: Anthony Ferrara, a developer advocate at Google, has published a blog post with some statistics showing the sorry state of affairs for website security involving PHP. After defining a list of secure and supported versions of PHP, he used data from W3Techs to find a rough comparison between the number of secure installs and the number of insecure or outdated installs. After doing some analysis, Ferrara sets the upper bound on secure installs at 21.71%. He adds, "These numbers are optimistic. That's because we're counting all version numbers that are maintained by a distribution as secure, even though not all installs of that version number are going to be from a distribution. Just because 5.3.3 is maintained by CentOS and Debian doesn't mean that every install of 5.3.3 is maintained. There will be a small percentage of installs that are from-source. Therefore, the real 'secure' number is going to be less than quoted." Ferrara was inspired to dig into the real world stats after another recent discussion of responsible developer practices.

Stephen Pinker and Andrew Mack have an article in Slate going through many of the statistics for things like homicide rates, child abuse, wars, and even autocracy vs. democracy. They're all trending in the right direction. Maybe not fast, or even fast enough, but it's getting better.

They say, "Too much of our impression of the world comes from a misleading formula of journalistic narration. Reporters give lavish coverage to gun bursts, explosions, and viral videos, oblivious to how representative they are and apparently innocent of the fact that many were contrived as journalist bait. Then come sound bites from "experts" with vested interests in maximizing the impression of mayhem: generals, politicians, security officials, moral activists. The talking heads on cable news filibuster about the event, desperately hoping to avoid dead air. Newspaper columnists instruct their readers on what emotions to feel. There is a better way to understand the world. ... An evidence-based mindset on the state of the world would bring many benefits."

Cause and Effect: How a Revolutionary New Statistical Test Can Tease Them Apart 137

Posted by timothy
from the submission-caused-post dept.
KentuckyFC writes Statisticians have long thought it impossible to tell cause and effect apart using observational data. The problem is to take two sets of measurements that are correlated, say X and Y, and to find out if X caused Y or Y caused X. That's straightforward with a controlled experiment in which one variable can be held constant to see how this influences the other. Take for example, a correlation between wind speed and the rotation speed of a wind turbine. Observational data gives no clue about cause and effect but an experiment that holds the wind speed constant while measuring the speed of the turbine, and vice versa, would soon give an answer. But in the last couple of years, statisticians have developed a technique that can tease apart cause and effect from the observational data alone. It is based on the idea that any set of measurements always contain noise. However, the noise in the cause variable can influence the effect but not the other way round. So the noise in the effect dataset is always more complex than the noise in the cause dataset. The new statistical test, known as the additive noise model, is designed to find this asymmetry. Now statisticians have tested the model on 88 sets of cause-and-effect data, ranging from altitude and temperature measurements at German weather stations to the correlation between rent and apartment size in student accommodation.The results suggest that the additive noise model can tease apart cause and effect correctly in up to 80 per cent of the cases (provided there are no confounding factors or selection effects). That's a useful new trick in a statistician's armoury, particularly in areas of science where controlled experiments are expensive, unethical or practically impossible.

U.S. Passenger Vehicle Fleet Dirtier After 2008 Recession 176

Posted by timothy
from the very-very-dirty dept.
MTorrice writes The 2008 recession hammered the U.S. auto industry, driving down sales of 2009 models to levels 35% lower than those before the economic slump. A new study has found that because sales of new vehicles slowed, the average age of the U.S. fleet climbed more than expected, increasing the rate of air pollutants released by the fleet.

In 2013, the researchers studied the emissions of more than 68,000 vehicles on the roads in three cities—Los Angeles, Denver, and Tulsa. They calculated the amount of pollution released per kilogram of fuel burned for the 2013 fleet and compared the rates to those that would have occurred if the 2013 fleet had the same age distribution as the prerecession fleet. For the three cities, carbon monoxide emissions were greater by 17 to 29%, hydrocarbons by 9 to 14%, nitrogen oxide emissions by 27 to 30%, and ammonia by 7 to 16%.

"Advanced Life Support" Ambulances May Lead To More Deaths 112

Posted by timothy
from the bring-the-machine-that-goes-beeeeeeeeeep dept.
HughPickens.com writes Jason Kane reports at PBS that emergency treatments delivered in ambulances that offer "Advanced Life Support" for cardiac arrest may be linked to more death, comas and brain damage than those providing "Basic Life Support." "They're taking a lot of time in the field to perform interventions that don't seem to be as effective in that environment," says Prachi Sanghavi. "Of course, these are treatments we know are good in the emergency room, but they've been pushed into the field without really being tested and the field is a much different environment." The study suggests that high-tech equipment and sophisticated treatment techniques may distract from what's most important during cardiac arrest — transporting a critically ill patient to the hospital quickly.

Basic Life Support (BLS) ambulances stick to simpler techniques, like chest compressions, basic defibrillation and hand-pumped ventilation bags to assist with breathing with more emphasis placed on getting the patient to the hospital as soon as possible. Survival rates for out-of-hospital cardiac arrest patients are extremely low regardless of the ambulance type with roughly 90 percent of the 380,000 patients who experience cardiac arrest outside of a hospital each year not surviving to hospital discharge. But researchers found that 90 days after hospitalization, patients treated in BLS ambulances were 50 percent more likely to survive than their counterparts treated with ALS. Not everyone is convinced of the conclusions. "They've done as much as they possibly can with the existing data but I'm not sure that I'm convinced they have solved all of the selection biases," says Judith R. Lave. "I would say that it should be taken as more of an indication that there may be some very significant problems here."

The TV ratings company revealed to the Wall Street Journal that it's planning to begin tracking viewership of online video services like Netflix and Amazon Prime Instant Video in December by analyzing the audio of shows that are being streamed. The new ratings will come with a lot of caveats—they won't track mobile devices and won't take into account Netflix's large global reach—but they will provide a sense for the first time which Netflix shows are the most popular. And if the rest of the media world latches onto these new ratings as a standard, Netflix won't be able to ignore them."

NVIDIA SHIELD Tablet Android Lollipop Update Performance Explored 57

Posted by timothy
from the stats-and-figures dept.
MojoKid writes Last week, NVIDIA offered information regarding its Android Lollipop update for the SHIELD Tablet and also revealed a new game bundle for it. This week, NVIDIA gave members of the press early access to the Lollipop update and it will also be rolling out to the general public sometime later today. Some of the changes are subtle, but others are more significant and definitely give the tablet a different look and feel over the original Android KitKat release. Android Lollipop introduces a new "material design" that further flattens out the look of the OS. Google seems to have taken a more minimalist approach as everything from the keyboard to the settings menus have been cleaned up considerably. Many parts of the interface don't have any markings except for the absolute necessities. While the OS definitely feels more fluid and responsive, the default look isn't always better, depending on your personal view. The app tray for example has a plain, white background which looks kind of jarring if you've using a colorful background. And finding the proper touch points for things like a settings menu or clearing notifications isn't always clear. Performance-wise, NVIDIA's Shield Tablet showed significantly better performance on Lollipop for general compute tasks in benchmarks like Mobile XPRT but lagged behind Kit Kat in graphics performance slightly, which could be attributed to driver optimization.
