GTK+ Developers Call For Help To Finish Cross-Platform OpenGL Support

SlashDot - Sun, 11/16/2014 - 11:29am
jones_supa writes OpenGL support under GTK is getting into good shape for providing a nice, out-of-the-box experience by default on key platforms for the GTK+ 3.16 / GNOME 3.16 release in March. For a few weeks now within mainline GTK+ has been native OpenGL support and as part of that a new GtkGLArea widget for allowing OpenGL drawing within GTK applications. Since that initial work landed, there's been more GTK+ OpenGL code progressing that right now primarily benefits Linux X11 and Wayland users. While good progress is being made and improvements still ongoing to the GNOME toolkit, GNOME developers are requesting help in ensuring other GTK+ backends can benefit from this OpenGL support. If you are using or planning to use GTK+ 3 on Windows or OS X, and you know how to use OpenGL on those two platforms, please consider helping out the GTK+ developers by implementing the GdkGLContext API using WGL and AppleGL.

Can the US Actually Cultivate Local Competition in Broadband?

SlashDot - Sun, 11/16/2014 - 10:32am
New submitter riskkeyesq writes with a link to a blog post from Dane Jasper, CEO of Sonic.net, about what Jasper sees as the deepest problem in the U.S. broadband market and the Internet in general: "There are a number of threats to the Internet as a system for innovation, commerce and education today. They include net neutrality, the price of Internet access in America, performance, rural availability and privacy. But none of these are the root issue, they're just symptoms. The root cause of all of these symptoms is a disease: a lack of competition for consumer Internet access." Soft landings for former legislators, lobbyists disguised as regulators, hundreds of thousands of miles of fiber sitting unused, the sham that is the internet provider free market is keeping the US in a telecommunications third-world. What, exactly, can American citizens do about it? One upshot,iIn Jasper's opinion (hardly disinterested, is his role at CEO at an ISP that draws praise from the EFF for its privacy policies) is this: "Today’s FCC should return to the roots of the Telecom Act, and reinforce the unbundling requirements, assuring that they are again technology neutral. This will create an investment ladder to facilities for competitive carriers, opening access to build out and serve areas that are beyond our reach today."

For Some Would-Be Google Glass Buyers and Devs, Delays May Mean Giving Up

SlashDot - Sun, 11/16/2014 - 9:27am
ErnieKey writes with a Reuters story that says Google's Glass, not yet out for general purchase, has been wearing on the patience of both developers and would-be customers: "After an initial burst of enthusiasm, signs that consumers are giving up on Glass have been building.' Is it true that Google Goggles are simply not attractive to wear? Or perhaps it's the invasion of privacy that is deterring people from wearing them. Regardless, Google needs to change something quickly before they lose all their potential customers. From the article: Of 16 Glass app makers contacted, nine said that they had stopped work on their projects or abandoned them, mostly because of the lack of customers or limitations of the device. Three more have switched to developing for business, leaving behind consumer projects. Plenty of larger developers remain with Glass. The nearly 100 apps on the official website include Facebook and OpenTable, although one major player recently defected: Twitter. "If there was 200 million Google Glasses sold, it would be a different perspective. There's no market at this point," said Tom Frencel, the chief executive of Little Guy Games, which put development of a Glass game on hold this year and is looking at other platforms, including the Facebook-owned virtual-reality goggles Oculus Rift. Several key Google employees instrumental to developing Glass have left the company in the last six months, including lead developer Babak Parviz, electrical engineering chief Adrian Wong, and Ossama Alami, director of developer relations.

Machine Learning Used To Predict Military Suicides

SlashDot - Sun, 11/16/2014 - 8:26am
HughPickens.com (3830033) writes David Wagner writes that a predictive computer model using machine learning methods is helping to identify soldiers in the United States Army most likely to commit suicide. Computers combed through data on more than 40,000 soldiers who'd been hospitalized for mental health problems looking at 421 variables on each soldier drawn from 38 military data systems. Using a method known as "machine learning," the researchers identified roughly two dozen factors that are most important in predicting soldiers most likely to commit suicide. The soldiers most likely to take their own lives were men with past suicidal behavior and a history of psychiatric disorders and criminal offenses, including weapons possession and verbal assaults. Soldiers with hearing loss also faced heightened risk — a strong indicator that they had suffered a head injury. So did enlisting in the Army after age 27, most likely because those soldiers had already experienced trouble finding their way in life. "There's this group that comes to the Army later in life — they're smart, they have skills, they tend not to be married and they have no career or have left a career to join," Dr. Kessler said. "We don't know why they should be at higher risk, but they appear to be." Murray Stein, co-author of the new study, found that among soldiers recently discharged from psychiatric hospitals, more than half of suicides were committed by just five percent of patients. "The most impressive thing is that they identified this high-risk group in the hospital, and by just focusing on one in 20 of them, you're really dramatically improving your ability to predict," says Dr. Mark Olfson, a professor of psychiatry at Columbia University who was not involved in the study. "Clinicians don't do a very good job predicting suicide risk, even though we think we do."

3D Printed Art Smaller Than an Ant's Forehead

SlashDot - Sun, 11/16/2014 - 5:25am
ErnieKey (3766427) writes Artist Jonty Hurwitz has created the world's smallest sculptures: nanosculptures, no wider than a human hair and unable to be seen without an electron microscope, created using a specialized 3D printing process. Hurwitz says this project was 'Art, literally created with Quantum Physics.' While this seems quite a claim, it seems to be very well deserved. Hurwitz enlisted a team of approximately 15 people to help him bring his vision to life. After scanning his models in a 200-camera array, the sculptures were printed — with advice from the Weizmann Institute of Science — using a 3D print technique by the Institute of Microstructure Technology at the Karlsruhe Institute of Technology, with multiphoton lithography used for the fine detail work.

How To Anesthetize an Octopus

SlashDot - Sun, 11/16/2014 - 2:28am
sciencehabit writes Researchers have figured out how to anesthetize octopuses so the animals do not feel pain while being transported and handled during scientific experiments. In a study published online this month in the Journal of Aquatic Animal Health, researchers report immersing 10 specimens of the common octopus in seawater with isoflurane, an anesthetic used in humans. They gradually increased the concentration of the substance from 0.5% to 2%. The investigators found that the animals lost the ability to respond to touch and their color paled, which means that their normal motor coordination of color regulation by the brain was lost, concluding that the animals were indeed anesthetized. The octopuses then recovered from the anesthesia within 40 to 60 minutes of being immersed in fresh seawater without the anesthetic, as they were able to respond to touch again and their color was back to normal.

Low Cost Ground Robot Chassis That Can Traverse Challenging Obstacles

SlashDot - Sat, 11/15/2014 - 11:26pm
Hallie Siegel writes In order for a robot to be useful in our world, it must be able to traverse unpredictable obstacles, including stairs. But currently available robot chassis tend to be either too small or extremely expensive, and most platform kits cannot leave a controlled environment – a huge problem for makers who want to get outside the lab or workshop. This has been an extremely hard problem for roboticists to solve, but the Ground Drone Project wants to change all that with its low-cost ground robot chassis. Check out this innovative design. (Currently, the project is raising money through Kickstarter; if it succeeds, "the instructions and bill of materials will be available for all.")

Billly Gates (198444) writes "What would be unthinkable a decade ago is Visual Studio supporting W3C HTML and CSS and now apps on other platforms. Visual Studio 2015 preview is available for download which includes support for LLVM/Clang, Android development, and even Linux development with Mono using Xamarin. A little more detail is here. A tester also found support for Java, ANT, SQL LITE, and WebSocket4web. We see IE improving in terms of more standards and Visual Studio Online even supports IOS and MacOSX development. Is this a new Microsoft emerging? In any case it is nice to have an alternative to Google tools for Android development."

US DOE Sets Sights On 300 Petaflop Supercomputer

SlashDot - Sat, 11/15/2014 - 6:34pm
dcblogs writes U.S. officials Friday announced plans to spend $325 million on two new supercomputers, one of which may eventually be built to support speeds of up to 300 petaflops. The U.S. Department of Energy, the major funder of supercomputers used for scientific research, wants to have the two systems – each with a base speed of 150 petaflops – possibly running by 2017. Going beyond the base speed to reach 300 petaflops will take additional government approvals. If the world stands still, the U.S. may conceivably regain the lead in supercomputing speed from China with these new systems. How adequate this planned investment will look three years from now is a question. Lawmakers weren't reading from the same script as U.S. Energy Secretary Ernest Moniz when it came to assessing the U.S.'s place in the supercomputing world. Moniz said the awards "will ensure the United States retains global leadership in supercomputing." But Rep. Chuck Fleischmann (R-Tenn.) put U.S. leadership in the past tense. "Supercomputing is one of those things that we can step up and lead the world again," he said.

Alleged Satellite Photo Says Ukraine Shootdown of MH17

SlashDot - Sat, 11/15/2014 - 4:36pm
theshowmecanuck (703852) writes A group calling itself the Russian Union of Engineers has published a photograph, picked up by many news organizations (just picked one, Google it yourself to find more), claiming to show that MH17 was shot down by a Ukrainian fighter plane. The interesting thing is the very quick ad hoc crowd sourced debunking of the photograph using tools from Google maps, online photos/data, to their own domain knowledge backed up with the previous information. It would be interesting to understand who the "Russian Union of Engineers" are and why they in particular were chosen to release this information.

Real Steampunk Computer Brought Back To Life

SlashDot - Sat, 11/15/2014 - 3:36pm
New submitter engineerguy writes We discovered a 100 year old 19th century computer that does Fourier analysis with just gears spring and levers. It was locked in a glass case at the University of Illinois Department of Mathematics. We rebuilt a small part of the machine and then for two years thoroughly photographed and filmed every part part of the machine and its operation. The results of this labor of love are in the video series (short documentary), which is 22 minutes long and contains stunning footage of the machine in action — including detailed descriptions of how it operates. The photos are collected in a free book (pdf) . The computer was designed by Albert Michelson, who was famous for the Michelson-Morley experiment; he was also the first American to win a Nobel Prize in physics.

Former Police Officer Indicted For Teaching How To Pass a Polygraph Test

SlashDot - Sat, 11/15/2014 - 2:41pm
George Maschke (699175) writes On Friday afternoon, the U.S. Department of Justice announced the indictment (2.6 mb PDF) of Douglas Gene Williams, a 69-year-old former Oklahoma City police polygraphist turned anti-polygraph activist for teaching two undercover agents posing as federal law enforcement applicants how to pass (or beat) a polygraph test. Williams offers instruction on how to pass polygraph tests through his website, Polygraph.com, which remains online. Marisa Taylor of McClatchy, who has been covering polygraph policy issues for several years, has written an informative report. This appears to be a case where an individual was targeted for criminal prosecution to suppress speech that the U.S. government dislikes. AntiPolygraph.org, which may also have been the target of an attempted entrapment, has a commentary.

To that end, after years of tooling around with command line and vim, I'm starting a programming bootcamp in early December. I used to think I wanted to go into ed tech. But the more I think about it, the more I just want to contribute to the most important work I can using my new skills — mostly JavaScript (with a strong interest in graph databases). Ideally an organization that does bold, direct humanitarian work for the people who need it most. So where should I apply to work when I finish bootcamp next March? Who's the MSF of the tech world?

Japanese Maglev Train Hits 500kph

SlashDot - Sat, 11/15/2014 - 12:15pm
An anonymous reader writes Japan has now put 100 passengers on a Maglev train doing over 500kph. That's well over twice as fast as the fastest U.S. train can manage, and that only manages 240kph on small sections of its route. The Japanese Shinkansen is now running over 7 times times as fast as the average U.S. express passenger train. 500kph is moving towards the average speed of an airliner. Add the convenience of no boarding issues, and city-centre to city-centre travel, and the case for trains as mass-transport begins to look stronger.

New Trial Brings Skype to (Some) Browsers

SlashDot - Sat, 11/15/2014 - 11:16am
Ars Technica reports that Microsoft has begun giving some users a taste of a new version of Skype, with a big difference compared to previous ones: the new one (tested by users on an invitation basis) is browser based. Rather than using the existing WebRTC standard, though (eschewed as too complex), Microsoft has developed a separate spec called ORTC (Object RTC), which is designed to offer similar capabilities but without mandating this same call setup system. Both Microsoft and Google are contributing to this spec, as are representatives from companies with video conferencing, telephony, and related products. ORTC isn't currently blessed as a W3C project, though the ORTC group has proposed integrating ORTC into WebRTC to create WebRTC 1.1 and including parts of ORTC into WebRTC 1.0. For now at least, video or audio chat therefore requires a plug-in, and requires Internet Explorer 10, or recent Firefox or Chrome browsers, and a current Safari on Mac OS X. Also at TechCrunch, among others, which notes that text chat (though as mentioned, not video or audio) will work with the new Skype under ChromeOS, too.

R. A. Montgomery, Creator of the "Choose Your Own Adventure" Books, Dead At 78

SlashDot - Sat, 11/15/2014 - 10:19am
Dave Knott writes Raymond Almiran Montgomery, original publisher and author of the incredibly popular "Choose Your Own Adventure" book series for children, the 4th bestselling children's series of all time, has died at the age of 78. In 1975, Montgomery founded a small press and when, in 1977, Ed Packard submitted an innovative book for young readers, "Sugarcane Island", Montgomery immediately saw it for what it was: a role-playing game in book form. He leapt at the chance to publish it, and launched a series, writing the second book, "Journey Under The Sea", himself. When Montgomery went through a divorce and sold his stake in the press to his ex-wife, he took the series, renamed as "Choose Your Own Adventure", to Bantam. The books went on to sell more than 250 million copies across 230 titles in 40 languages. Montgomery's interests also extended to new technology, adapting the series to the Atari console in 1984. He was also responsible for the Comic Creator software on Apple's Macintosh computers. Montgomery died on November 9th. The cause of death was not disclosed.

Comcast Kisses-Up To Obama, Publicly Agrees On Net Neutrality

SlashDot - Sat, 11/15/2014 - 9:28am
MojoKid writes Comcast is one of two companies to have earned Consumerist's "Worst Company in America" title on more than one occasion and it looks like they're lobbying for a third title. That is, unless there's another explanation as to how the cable giant can claim (with straight face) that it's in agreement with President Barack Obama for a free and open Internet. Comcast issued a statement of its own saying they back the exact same things, it just doesn't want to go the utility route. Comcast went on to list specific bullet points that they're supposedly in wholehearted agreement with, such as: Free and open Internet. We agree — and that is our practice. No blocking. We agree — and that is our practice. No throttling. We agree — and that is our practice. Increased transparency. We agree — and that is our practice. No paid prioritization. We agree — and that is our practice. Really? Comcast conveniently fails to address the giant elephant in the room whose name is Netflix. Earlier this year, Netflix begrudgingly inked a multi-year deal with Comcast in which the streaming service agreed to pay a toll to ensure faster delivery into the homes of Comcast subscribers, who prior to the deal had been complaining of frequent buffering and video degradation when watching content on Netflix. Comcast would undoubtedly argue that it's not a paid fast lane, but it's hard to see the deal as anything other than that.

The Downside to Low Gas Prices

SlashDot - Sat, 11/15/2014 - 8:27am
HughPickens.com writes Pat Garofalo writes in an op-ed in US News & World Report that with the recent drop in oil prices, there's something policymakers can do that will offset at least some of the negative effects of the currently low prices, while also removing a constant thorn in the side of American transportation and infrastructure policy: Raise the gas tax. The current 18.4 cent per gallon gas tax has not been raised since 1993, making it about 11 cents per gallon today, in constant dollars. Plus, as fuel efficiency has gotten better and Americans have started driving less, the tax has naturally raised less revenue anyway. And that's a problem because the tax fills the Highway Trust Fund, which is, not to put too fine a point on it, broke so that in recent years Congress has had to patch it time and time again to fill the gap. According to the Tax Policy Center's Howard Gleckman, if Congress doesn't make a move, "it will fumble one of those rare opportunities when the economic and policy stars align almost perfectly." The increase can be phased in slowly, a few cents per month, perhaps, so that the price of gas doesn't jump overnight. When prices eventually do creep back up thanks to economic factors, hopefully the tax will hardly be noticed. Consumers are already starting to buy the sort of gas-guzzling vehicles, including Hummers, that had been going out of style as gas prices rose; that's bad for both the environment and consumers, because gas prices are inevitably going to increase again. According to data from the U.S. Energy Information Administration, taxes last year, even before the current drop in prices, made up 12 percent of the cost of a gallon of gasoline, down from 28 percent in 2000. And compared to other developed countries, US gas taxes are pretty much a joke. While we're at it, an even better idea, as a recent report from the Urban Institute makes clear, would be indexing the gas tax to inflation, so this problem doesn't consistently arise. "The status quo simply isn't sustainable, from an infrastructure or environmental perspective," concludes Garofalo. "So raise the gas tax now; someday down the line, it will look like a brilliant move."
