Comment: Re:Does this mean we don't need dark matter anymor (Score 1) 57 57

As far as I can tell, dark matter is just the modern equivalent of the cosmological constant - "I dunno, but if we fudge-factor in n it all works!"

Nope. Dark energy is that: we have a large-scale measurement we can't explain, but we have to call it something, and since it might not actually be constant, they didn't want to call it "cosmological constant".

Dark matter explains galactic rotation rates and lensing, and also predicted the CMBR data with some precision: the predictions of dark/familiar matter made from galactic rotation matched the observed ratio in the early universe measured by the CMBR probes.

Lots of black holes were among the MACHOs theories for dark matter, but the CMBR data confirmed the WIMPs theories had it right. We may not no much about these particles, but black holes, brown dwarfs, and so on are right out.

How Bad User Interfaces Can Ruin Lives 36 36

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.

There's no difference between "area where time moves slower" and "gravity well" in general relativity, which shows great robustness as theories go. "Time moves faster" (or a large anti-gravity well) wouldn't cause the lensing we see.

Anyhow, dark matter explains the CMBR data and galaxy rotation rates and lensing, which is pretty good. Any alternative proposal would need to explain all three.

Hypocrite much? Or was I whooshed?

It's impossible to tell the difference between the most crazy hyperbole and sincere SJWs these days. That's what makes the Reddit game "Stormfront or SJW" so much fun! We're beyond Poe's law now to some surreal place through the looking glass.

The MESS is caused by the baby boom and Greece's liberal government funded pensions

I'd argue that this MESS is caused by the high level of labor and business regulation in Greece.

Ireland got into a big debt crisis as well, but because it has a high level of economic freedom, it was able to exit its rescue program due to economic growth (despite "austerity").

Spain has just begun to reform its labor and business regulations, and it is finally showing some return to economic growth

Germany had the Hartz labor Reforms before the economic crisis, so it never needed a rescue.

Greece remains last in the Eurozone in economic freedom rankings and highest in the Eurozone for corruption rankings.

Prototype Wave Energy Device Passes Grid-Connected Pilot Test 14 14

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 27 27

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 89 89

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 29 29

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! 57 57

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 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.

The DARPA Robotics Challenge Was a Bust; Let's Try Again 23 23

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.
