Ranking Soccer Players By Following the Bouncing Ball 142

sciencehabit excerpts from an interesting report on statistics for soccer, in the stats-obsessed world of sports: "Only a handful of soccer ranking systems exist, most of which rely on limited information: the number of goals scored in a match, the number of goals assisted, and some indices of a match's difficulty and importance. ... So researchers turned to an unlikely source: social networks. Applying the kinds of mathematical techniques used to map Facebook friends and other networks, the team created software that can trace the ball's flow from player to player. As the program follows the ball, it assigns points for precise passing and for passes that ultimately lead to a shot at the goal. Whether the shot succeeds doesn't matter. Only the ball's flow toward the goal and each player's role in getting it there factors into the program's point system, which then calculates a skill index for each team and player."

Google Urged To Let Personal Data Fade Away 116

jee4all writes with this excerpt from E-week: "Researchers say personal information should 'degrade' — becoming less specific over time — to protect users' privacy. Rather than amassing personal data and holding on to it as long as legally possible, companies such as Google should allow the data to degrade over time, according to researchers. In an interview with the BBC this week, Dutch researcher Harold van Heerde discussed his work on the idea of allowing data to becomes less specific over time. Letting the specifics gradually disappear could protect consumer privacy while also meeting the needs of service providers, he said."

Deformable Liquid Mirrors For Adaptive Optics 196

eldavojohn writes "Want to make a great concave mirror for your telescope? Put a drop of mercury in a bowl and spin the bowl. The mercury will spread out to a concave reflective surface smoother than anything we can make with plain old glass right now. The key problem in this situation is that the bowl will always have to point straight up. MIT's Technology Review is analyzing a team's success in combating problems with bringing liquid mirrors into the practical applications of astronomy. To fight the gravity requirement, the team used a ferromagnetic liquid coated with a metal-like film and very strong magnetic fields to distort the surface of that liquid as they needed. But this introduces new non-linear problems of control when trying to sync up several of these mirrors similar to how traditional glass telescopes use multiple hexagonal mirrors mounted on actuators. The team has fought past so many of these problems plaguing liquid mirrors that they produced a proof of concept liquid mirror just five centimeters across with 91 actuators cycling at one kilohertz and the ability to linearize the response of the liquid. And with that, liquid mirrors take a giant leap closer to practicality."

FCC Vote Marks Effort To Take Greater Control of the Web 323

GovTechGuy writes "The FCC voted today to open an inquiry into how the broadband industry is regulated, the first step in a controversial attempt to assert greater regulatory control over Internet service providers. In a 3-2 vote the Democratic members of the Commission voted to move forward with the FCC's proposal to reclassify broadband as a telecom service, increasing the regulation it is subject to. The move also has large implications for net neutrality, which FCC Commissioner Julius Genachowski has made a focus under his watch."

Bluecherry Releases GPL'd MPEG-4 Driver 45

azop writes "Today Bluecherry released a GPL'd driver for its multiple-input MPEG-4 hardware compression cards. The driver supports audio and video capture from 4-, 8-, and 16-channel single-card encoders using the Video4Linux and ALSA APIs. More information about the driver and its features can be found on Bluecherry's development blog and on Ben Collins' personal blog. Bluecherry is the first Linux software company to release a complete driver based on Linux kernel APIs (Video4Linux and ALSA) for multiple-input hardware-compressed MPEG-4 capture cards under the GPL. The cards are designed for security applications (digital video recording), but other applications could potentially make use of the compressed streams and Video4Linux API integration. An H.264 version is 'in the works.'"

How Sperm Whales Offset Their Carbon Footprint Screenshot-sm 150

Boy Wunda writes "Scientists at Flinders University in South Australia found that in an awesome example of design by Mother Nature, Southern Ocean sperm whales offset their carbon footprint by simply defecating – an action that releases tons of iron a year and stimulates the growth of phytoplankton which absorb and trap carbon dioxide. If only we humans could say the same for our poop, which really doesn't do much more than just sit there." I'm going to do my part by buying some iron supplements and a can of chili, and heading off toward the ocean.

Developers' New Opportunity — Retailers' Open APIs 45

snydeq writes "Fatal Exception's Neil McAllister examines the recent trend among retailers to provide outside developers access to open APIs — one that promises opportunity for developers to transform retailer data transparency into lucrative business models. But whether the trend lives up to its potential remains to be seen, especially given the hurdles small and midsize businesses face launching programs similar to those in place at Amazon, Zappos, and Sears. McAllister writes, 'There's a definite "Field of Dreams" quality to any such undertaking. Ask any company that hosts an open source software project how many outsiders actually commit code changes on a regular basis and you're likely to hear a discouraging figure. Similarly, just because a retailer builds an API doesn't mean anyone will actually use it. Given the uncertain prospects of return, it can be difficult to justify such an investment.'"

Supreme Court Says Gov't Employee Texts Not Private 263

e9th writes "The Supreme Court, in a 9-0 ruling, has decided that government employers are entitled to examine all text messages sent with government-provided devices, even if the employee has agreed to pay for any excess message charges out of his own pocket. While the ruling only applies to government employees (at all levels), it may give private sector employees something to think about when using employer-provided devices."

US Dept. of Energy Wants Bigger Wind Energy Ideas 252

coondoggie writes "The Department of Energy wants to kick up the research and development of offshore wind projects as it looks to achieve its goal of producing 20% of the country's electricity from wind farms by 2030. The DOE Wind Program is looking to focus on what it calls specific advanced technology, gigawatt-scale demonstration projects that can be carried out by partnerships with a wide range of eligible organizations and stimulate cost-effective offshore wind energy deployment in coastal and Great Lakes regions of the country. The agency is also looking for more research that can help address market barriers in order to facilitate deployment and reduce technical challenges facing the entire industry, as well as technology that will reduce cost of offshore wind energy through innovation and testing."

First Self-Replicating Creature Spawned In Conway's Game of Life 241

Calopteryx writes "New Scientist has a story on a self-replicating entity which inhabits the mathematical universe known as the Game of Life. 'Dubbed Gemini, [Andrew Wade's] creature is made of two sets of identical structures, which sit at either end of the instruction tape. Each is a fraction of the size of the tape's length but, made up of two constructor arms and one "destructor," play a key role. Gemini's initial state contains three of these structures, plus a fourth that is incomplete. As the simulation progresses the incomplete structure begins to grow, while the structure at the start of the tape is demolished. The original Gemini continues to disassemble as the new one emerges, until after nearly 34 million generations, new life is born.'"

FSF Starts Anti-ACTA Campaign 173

judgecorp writes "Free Software Foundation president Richard Stallman has said in a blog post that the ACTA file-sharing proposals punish users unfairly. He wrote, 'Any time there is a proposal to change things for the worse, the obvious way to oppose it is to campaign for the status quo. To campaign for the status quo suggests the approach of singing its praises; thus, praising WIPO is a natural way to highlight how ACTA is a step for the worse. However, where there have been previous changes for the worse, lauding the status quo tends to legitimize them. The past 20 years have seen global waves of harmful changes in copyright law — some promoted by WIPO. To confront a further assault by presenting the status quo as ideal means we stop fighting to reverse them. It means that our adversaries need only propose a further affront to our rights to gain our acceptance of their last affront. Instead of making the status quo our ideal, we should demand positive changes to recover freedoms already lost.' The FSF has launched a petition against the ACTA proposals."

Study Shows Monkeys Like Watching TV Screenshot-sm 103

According to a Japanese study, monkeys are not immune to the siren call of the idiot box. It seems rhesus monkeys enjoy watching videos of circus animals. From the article: "The study found that when the monkey was witnessing the acrobatic performances of circus animals on a television screen, the frontal lobe area of its brain became vigorously active. The activity in such an area was significant in reflecting the monkey's pleasure, as the human equivalent is a neurological area associated with triggering delight in a baby when it sees the smile of its mother."

California Tracks Parolees With GPS, Then Ignores Alerts 160

An anonymous reader writes "Several years ago, California decided to require high-risk parolees, such as gang members and sex offenders, to wear GPS monitoring devices. The idea was to relay location information to law enforcement to ensure that the convicts stay where they're supposed to. Unfortunately, the state often misses acting on those alerts, making the devices both a lesson in the pitfalls of technology management and a massive exercise in largely useless spending."
