Supercomputing Cluster Immersed In Oil Yields Extreme Efficiency 6 6

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 51 51

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 15 15

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! 48 48

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 237 237

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 19 19

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 247 247

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 82 82

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 52 52

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? 257 257

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 24 24

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."

First Windows 10 RTM Candidate Appears 131 131

Mark Wilson reports that the first RTM candidate for Windows 10 has been spotted: build 10176. Leaks and sources have suggested the company intends to finalize the operating system later this week, perhaps as early as July 9th. This would give Microsoft almost three weeks to distribute it to retailers and devicemakers before the July 29th launch date. "While the RTM process has been a significant milestone for previous releases of Windows, it’s more of a minor one for Windows 10. Microsoft is moving Windows 10 to a 'Windows as a service' model that means the operating system is regularly updated."

Proposed Regulation Could Keep 3D-printed Gun Blueprints Offline For Good 319 319

SonicSpike sends a report on a proposed update to the International Traffic in Arms (ITAR) regulations which could shut down the sharing of files for 3D printed gun parts over the internet. "Hidden within the proposal, which restricts what gear, technology, and info can and cannot be exported out of the U.S., is a ban on posting schematics for 3D printed gun parts online." This follows a lawsuit from Cody Wilson and Defense Distributed back in May fighting the federal government's command to remove blueprints for the "Liberator" 3D-printed gun from their website. A senior official at the U.S. State Department said, "By putting up a digital file, that constitutes an export of the data. If it's an executable digital file, any foreign interests can get a hold of it."

Pluto Probe Back To Normal, Cause of Snafu Found 70 70

Tablizer writes: NASA has provided an update to the problem with the New Horizons probe that will fly by Pluto next week. "The investigation into the anomaly that caused New Horizons to enter "safe mode" on July 4 has concluded that no hardware or software fault occurred on the spacecraft. The underlying cause of the incident was a hard-to-detect timing flaw in the spacecraft command sequence that occurred during an operation to prepare for the close flyby. No similar operations are planned for the remainder of the Pluto encounter.
