Extreme Reduction Gearing Device Offers an Amazing Gear Ratio 34 34

ErnieKey writes: The 3D printed extreme reduction gearing device, created by long-time puzzle maker M. Oskar van Deventer, may leave you puzzled for its obvious applications, but the coaxial cranking mechanism offers potential in a variety of real-world applications with multi-colored gears that move in opposite directions at a ratio of 11,373,076 : 1. This 3D printed reduction gearing device is compact and multi-colored, and looks deceivingly simple at first glance. Developed through a complex algorithm, it could possibly offer potential as parts for machines like 3D printers, aerospace and automotive components, as well as perhaps robotics and a variety of motors.

Click-Fraud Trojan Politely Updates Flash On Compromised Computers 32 32

jfruh writes: Kotver is in many ways a typical clickfraud trojan: it hijacks the user's browser process to create false clicks on banner ads, defrauding advertisers and ad networks. But one aspect of it is unusual: it updates the victim's installation of Flash to the most recent version, ensuring that similar malware can't get in.

How Bad User Interfaces Can Ruin Lives 134 134

Lauren Weinstein writes: A couple of months ago, in "Seeking Anecdotes Regarding 'Older' Persons' Use of Web Services," I asked for stories and comments regarding experiences that older users have had with modern Web systems, with an emphasis on possible problems and frustrations. I purposely did not define "older" — with the result that responses arrived from users (or regarding users) self-identifying as ages ranging from their 30s to well into their 90s (suggesting that "older" is largely a point of view rather than an absolute). Before I began the survey I had some preconceived notions of how the results would appear. Some of these were proven correct, but overall the responses also contained many surprises, often both depressing and tragic in scope. The frustration of caregivers in these contexts was palpable. They'd teach an older user how to use a key service like Web-based mail to communicate with their loved ones, only to discover that a sudden UI change caused them to give up in frustration and not want to try again. When the caregiver isn't local the situation is even worse. While remote access software has proven a great boon in such situations, they're often too complex for the user to set up or fix by themselves when something goes wrong, remaining cut off until the caregiver is back in their physical presence.

Prototype Wave Energy Device Passes Grid-Connected Pilot Test 29 29

coondoggie writes: A prototype wave energy device advanced with backing from the Energy Department and U.S. Navy has passed its first grid-connected open-sea pilot testing. According to the DOE, the device, called Azura, was recently launched and installed in a 30-meter test berth at the Navy's Wave Energy Test Site (WETS) in Kaneohe Bay, on the island of Oahu, Hawaii. This pilot testing is now giving U.S. researchers the opportunity to evaluate the long-term performance of the nation’s first grid-connected 20-kilowatt wave energy converter (WEC) device to be independently tested by a third party—the University of Hawaii—in the open ocean, the DOE said.

Supercomputing Cluster Immersed In Oil Yields Extreme Efficiency 46 46

1sockchuck writes: A new supercomputing cluster immersed in tanks of dielectric fluid has posted extreme efficiency ratings. The Vienna Scientific Cluster 3 combines several efficiency techniques to create a system that is stingy in its use of power, cooling and water. VSC3 recorded a PUE (Power Usage Efficiency) of 1.02, putting it in the realm of data centers run by Google and Facebook. The system avoids the use of chiillers and air handlers, and doesn't require any water to cool the fluid in the cooling tanks. Limiting use of water is a growing priority for data center operators, as cooling towers can use large volumes of water resources. The VSC3 system packs 600 teraflops of computing power into 1,000 square feet of floor space.

Philips Is Revolutionizing Urban Farming With New GrowWise Indoor Farm 143 143

Kristine Lofgren writes: With arable land dwindling and the cost — both economically and environmentally — of growing and transporting food increasing, it's time to redefine farming. So Philips is creating a revolution with their new GrowWise indoor farm, which uses customized 'light recipes' in high-tech cells to grow plants that don't need pesticides or chlorine washes, and use a fraction of the water that traditional farming requires. The system can churn out 900 pots of basil a year in just one square meter of floor space, and bees keep things humming year-round for farming that is truly local, even in the middle of a city.

What Goes Into a Decision To Take Software From Proprietary To Open Source 36 36

Lemeowski writes: It's not often that you get to glimpse behind the curtain and see what led a proprietary software company to open source its software. Last year, the networking software company Midokura made a strategic decision to open source its network virtualization platform MidoNet, to address fragmentation in the networking industry. In this interview, Midokura CEO and CTO Dan Mihai Dumitriu explains the company's decision to give away fours years of engineering to the open source community, how it changed the way its engineers worked, and the lessons learned along the way. Among the challenges was helping engineers overcome the culture change of broadcasting their work to a broader community.

More Supermassive Black Holes Than We Thought! 65 65

LeadSongDog writes: The Royal Astronomical Society reports five supermassive black holes (SMBHs) that were previously hidden by dust and gas have been uncovered. The discovery suggests there may be millions more supermassive black holes in the universe than were previously thought. George Lansbury, a postgraduate student in the Centre for Extragalactic Astronomy, at Durham University, said: “For a long time we have known about supermassive black holes that are not obscured by dust and gas, but we suspected that many more were hidden from our view. Thanks to NuSTAR for the first time we have been able to clearly see these hidden monsters that are predicted to be there, but have previously been elusive because of their ‘buried’ state. Although we have only detected five of these hidden supermassive black holes, when we extrapolate our results across the whole Universe then the predicted numbers are huge and in agreement with what we would expect to see.”

"We Screwed Up," Says Reddit CEO In Formal Apology 350 350

An anonymous reader writes: After moderators locked up some of Reddit's most popular pages in protest against the dismissal of Victoria Taylor, and an online petition asking the company to fire CEO Ellen Pao reached more than 175,000 signatures over the weekend, Pao has issued an apology. The statement reads in part: "We screwed up. Not just on July 2, but also over the past several years. We haven't communicated well, and we have surprised moderators and the community with big changes. We have apologized and made promises to you, the moderators and the community, over many years, but time and again, we haven't delivered on them. When you've had feedback or requests, we haven't always been responsive. The mods and the community have lost trust in me and in us, the administrators of reddit. Today, we acknowledge this long history of mistakes. We are grateful for all you do for reddit, and the buck stops with me."

The DARPA Robotics Challenge Was a Bust; Let's Try Again 30 30

malachiorion writes: The DARPA Robotics Challenge, the biggest and most well-funded international robotics competition in years, was a failure. After years of grueling work on the part of brilliant roboticists around the world, and millions in funding from the Pentagon, the finals came and went with little to no coverage from the mainstream media. The only takeaway, for those who aren't extremely dialed into robotics, is that a ton of robots fell down in funny ways. There were winners, but considering how downgraded the tasks were, compared to the ones initially announced in 2012, it was closer to the first DARPA Grand Challenge, where none of the robot cars finished, than the Urban Challenge, which kicked off the race to build deployable driverless cars. So just as DARPA regrouped after that first fizzle of a race, here's my argument for Popular Science: It's time to do it again, and make falling, and getting up, mandatory.

Software Devs Leaving Greece For Good, Finance Minister Resigns 309 309

New submitter TheHawke writes with this story from ZDNet about the exodus of software developers from Greece. "In the last three years, almost 80 percent of my friends, mostly developers, left Greece," software developer Panagiotis Kefalidis told ZDNet. "When I left for North America, my mother was not happy, but... it is what it is." It's not just the software developers quitting either. The Greek Finance Minister Yanis Varoufakis also resigned. A portion of his resignation announcement reads: "Soon after the announcement of the referendum results, I was made aware of a certain preference by some Eurogroup participants, and assorted ‘partners’, for my ‘absence’ from its meetings; an idea that the Prime Minister judged to be potentially helpful to him in reaching an agreement. For this reason I am leaving the Ministry of Finance today."

Japanese and US Piloted Robots To Brawl For National Pride 97 97

jfruh writes: Japan may have just lost the Women's World Cup to the U.S., but the country is hoping for a comeback in another competition: a battle between giant robots. Suidobashi Heavy Industry has agreed to a challenge from Boston-based MegaBots that would involve titanic armored robots developed by each startup, the first of its kind involving piloted machines that are roughly 4 meters tall. "We can't let another country win this," Kogoro Kurata, who is CEO of Suidobashi, said in a video posted to YouTube. "Giant robots are Japanese culture."

Google's Waze Jumps Into the Ride-Sharing Business 69 69

An anonymous reader writes: Waze, the online mapping company owned by Google, is testing a ride-sharing service in Israel called RideWith. The service will allow commuters to pay drivers for rides to and from work. This is a hard limit — drivers can give no more than two rides per day. If the restriction remains after the initial test, it could be a simple way to avoid pseudo-professional drivers, and all the taxi-related legal problems that go with them (see: Uber). "RideWith calculates a cost based on the anticipated fuel consumption and 'depreciation' based on mileage, and the driver is free to accept or decline the ride accordingly." One can't help but speculate about future involvement with Google's autonomous car project.

Ask Slashdot: Have You Tried a Standing Desk? 291 291

An anonymous reader writes: Evidence is piling up that sitting down all day is really bad for you. I work primarily from home, and as I grow older, I'm starting to worry about long term consequences to riding a desk full-time. We talked about this a few years ago, but the science has come a long way since then, and so have the options for standing desks. My questions: do you use a standing desk? What kind of setup do you have? There are a lot of options, and a lot of manufacturers. Further studies have questioned the wisdom of standing all day, so I've been thinking about a standing/sitting combo, and just switching every so often. If you do this, do you have time limits or a particular frequency with which you change from sitting to standing?

I'm also curious about under-desk treadmills — I could manage slowly walking during parts of my work, and the health benefits are easy to measure. Also, any ergonomic tips? A lot of places seem to recommend: forearms parallel to the ground, top of monitor at eye level, and a pad for under your feet. Has your experience been the same? Those of you who have gone all-out on a motorized setup, was it worth the cost? The desks are dropping in price, but I can still see myself dropping upward of $1k on this, easily.

Chilling Effect of the Wassenaar Arrangement On Exploit Research 27 27

Bismillah writes: Security researchers are confused as to how the export control and licensing controls covering exploits affect their work. The upcoming Wassenaar restrictions were expected to discourage publication of such research, and now it's already started to happen. Grant Wilcox, writing his dissertation for the University of Northumbria at Newcastle, was forced to take a better-safe-than-sorry approach when it came time to release the vulnerabilities he found in Microsoft's EMET 5.1. "No legal consultation on the matter took place, but Wilcox noted that exploit vendors such as Vupen had started to restrict sales of their products and services because of new export control and licensing provisions under the Wassenaar Arrangement. ... Wilcox investigated the export control regulations but was unable to clarify whether it applied to his academic work. The university did not take part. He said the provisions defining which type of exploits and software are and aren't controlled were written in ambiguous language and appeared to contradict each other."
