Submission + - Wasserman Schultz won't Speak at Dem Convention After Wikileaks Revelations (cnn.com)

HughPickens.com writes: CNN reports that the head of the Democratic National Committee will not speak at the party's convention next week, a decision reached by party officials Saturday after emails surfaced that raised questions about the committee's impartiality during the Democratic primary. Debbie Wasserman Schultz, whose stewardship of the DNC has been under fire through most of the presidential primary process, will not have a major speaking role in an effort "to keep the peace" in the party, a Democrat familiar with the decision said. The revelation comes following the release of nearly 20,000 emails. One email appears to show DNC staffers asking how they can reference Bernie Sanders' faith to weaken him in the eyes of Southern voters. Another seems to depict an attorney advising the committee on how to defend Hillary Clinton against an accusation by the Sanders campaign of not living up to a joint fundraising agreement.

While I agree with the pattern you're pointing out the TSA seriously needs to go. The only reason it's still around is that it provides jobs for the unemployable.

If it's a jobs program we're looking for spend the money on replacing thousands of municipal waterworks running on pipes so corroded and plugged up that fire hydrants don't give enough pressure. Or spend the money creating a final say that will stop environmentalists from blocking desert solar power plants. Or finish making section 8 to break up the ghettos. Or clean out Chicago. There are a thousand other things that will pay back their costs. The TSA is a broken window.

Submission + - $5000 Student Loans Default the Most (theatlantic.com)

minstrelmike writes: You can read horror stories about people with $150,000 student loans, but they aren't the ones with the most problems. The "typical for-profit student is a 24-year-old from a first-generation family earning less than $40,000, who eventually drops out of school. The completion rates for two-year and four-year for-profit institutions is about 40 percent and 25 percent, respectively." These are the people most at risk of default.

Submission + - Cheaper Flow Batteries Using Vitamins Discovered (natureworldnews.com)

William Robinson writes: Scientists from Harvard University have discovered how to create flow batteries using organic molecules inspired by vitamin B2, which helps store energy from food in the body. With a few tweaks to the original B2 molecule, the scientists discovered a new group of organic molecules that make good candidates for alkaline flow batteries. The result of the discovery was a redox flow battery that demonstrates an open-circuit voltage approaching 1.2V, with a current efficiency of 99.7 percent and a capacity retention over 99.98 percent per cycle.

Submission + - SPAM: Napthlalene-derived carbon nanospheres for room temperature quantum computing

synaptic writes: In the journal Nature, scientists report the novel synthesis of carbon nanospheres from napthalene pyrolysis allowing room-temperature quantum computing. From the Phys.org article:

"We have demonstrated that a long conduction electron spin lifetime in metallic-like material made up of carbon nanospheres can be achieved at room temperature. This material was produced simply by burning naphthalene, the active ingredient in mothballs. The material is produced as a solid powder and handled in air. It can then be dispersed in ethanol and water solvents, or deposited directly onto a surface like glass. As the material was remarkably homogeneous, the measurements could be made on the bulk solid powder. This allowed us to achieve a new record electron spin lifetime of 175 nanoseconds at room temperature. This might not sound like a long time, but it exceeds the prerequisite for applications in quantum computing and is about 100 times longer than that found in graphene."

Submission + - Military coup in Turkey (jpost.com)

Iamthecheese writes: According to the Associated Press and other sources the Turkish military have taken over the country. They have imposed martial law and public television. The Telegraph reports low flying jets and gunfire. According to one Twitter post the Turkish Chief of Staff says Turkey's administration has been taken over completely by military. Jerusalem Post reports

If successful, the overthrow of President Tayyip Erdogan, who has ruled Turkey since 2003, would be one of the biggest shifts in power in the Middle East in years, transforming one of the most important U.S. allies in the region.

Prime Minister Binali Yildirim said the elected government remained in office. There was no immediate word from Erdogan. A source in his office said he was safe.

According to Wikipedia other coups in Turkey happened in 1960, 1971, 1980, and 1993.

Comment Blind interviews (Score 1) 200

Proving unbiased results is an old problem in science. It's a solved problem. The solution is applicable to many other fields of human endeavor. If you want to hire without bias have someone without hiring authority ask interview questions. Change the names on resumes to "candidate 1, candidate 2" etc. The hiring manager sees the resumes and answers but not the candidates. Sincerity is harder to judge but it's still easy to see who knows what they're talking about.

But Facebook doesn't want unbiased hiring. They want to preferentially hire certain people. Fuck Facebook and every other company with bigotry in its soul.

Submission + - 15 Year Old Bug in fMRI Software Could Invalidate 40,000 Brain Research Studies

HughPickens.com writes: Bec Crew reports at Science Alert that a new study suggests that a bug in functional magnetic resonance imaging (fMRI) software that has been in the system for the past 15 years could invalidate the results of some 40,000 papers. Since fMRI is one of the best tools scientists have to measure brain activity, and if it’s flawed, it means all those conclusions about what our brains look like during things like exercise, gaming, love, and drug addiction are wrong. "Despite the popularity of fMRI as a tool for studying brain function, the statistical methods used have rarely been validated using real data," say researchers led by Anders Eklund from Linköping University in Sweden. Scientists use fMRI scans to find sparks of activity in certain regions of the brain. During an experiment, a participant will be asked to perform a certain task, while a massive magnetic field pulsates through their body, picking up tiny changes in the blood flow of the brain. The trouble is that when scientists are interpreting data from an fMRI machine, they’re not looking at the actual brain. What they're looking at is an image of the brain divided into tiny 'voxels', then interpreted by a computer program. In their paper the researchers write: “the most common software packages for fMRI analysis (SPM, FSL, AFNI) can result in false-positive rates of up to 70%. These results question the validity of some 40,000 fMRI studies and may have a large impact on the interpretation of neuroimaging results.” A bug that's been sitting in a package called 3dClustSim for 15 years, fixed in May 2015, produced the bad results. The researchers also criticize the fMRI community for their “lamentable archiving and data-sharing practices” that prevent most of the discipline's body of work from ever being re-analysed.

Submission + - Consumer Reports calls for Tesla to Disable Autopilot (consumerreports.org)

parallel_prankster writes: Consumer Reports is calling on Tesla to disable its "Autopilot" feature that enables hands-free operation. Citing the recent fatal accident involving a car with Autopilot engaged, Consumer Reports labels the feature as "Too Much Autonomy Too Soon."
In an extensive article posted at the top of its website Thursday morning, Consumer Reports said Tesla should "disable hands-free operation until its system can be made safer." "By marketing their feature as ‘Autopilot,’ Tesla gives consumers a false sense of security," said Laura MacCleery, vice president of consumer policy and mobilization for Consumer Reports, in the article. "In the long run, advanced active safety technologies in vehicles could make our roads safer. But today, we're deeply concerned that consumers are being sold a pile of promises about unproven technology. 'Autopilot' can't actually drive the car, yet it allows consumers to have their hands off the steering wheel for minutes at a time. Tesla should disable automatic steering in its cars until it updates the program to verify that the driver's hands are on the wheel."

Tesla says it will continue development of Autopilot, insisting that drivers supported by Autopilot "remain safer than those operating without assistance."

angry tapir writes: In August it will be 35 years since of the release of version 1.0 of MS-DOS (or PC DOS as it was known at the time). Despite MS-DOS being long dead, the FreeDOS community has kept DOS alive, with the open source project having been founded some 22 years ago. I caught up with the founder of the project about the plans for the next version of FreeDOS and what keeps the open source OS alive.

Submission + - Physicist Simulate Sending Particles of Light Into the Past (earthmysterynews.com) 1

retroworks writes: While it doesn't demonstrate time travel to be possible, per se, University of Queensland, Australia, physicists have shown how the concept can work via photons. Actual time travel would require a very fast revolution of a black hole, or "wormhole", according to the review. The abstract for the paper "Experimental simulation of closed timelike curves" http://www.nature.com/ncomms/2... states:

"Closed timelike curves are among the most controversial features of modern physics. As legitimate solutions to Einstein’s field equations, they allow for time travel, which instinctively seems paradoxical. However, in the quantum regime these paradoxes can be resolved, leaving closed timelike curves consistent with relativity. The study of these systems therefore provides valuable insight into nonlinearities and the emergence of causal structures in quantum mechanics—essential for any formulation of a quantum theory of gravity. Here we experimentally simulate the nonlinear behaviour of a qubit interacting unitarily with an older version of itself, addressing some of the fascinating effects that arise in systems traversing a closed timelike curve. These include perfect discrimination of non-orthogonal states and, most intriguingly, the ability to distinguish nominally equivalent ways of preparing pure quantum states. Finally, we examine the dependence of these effects on the initial qubit state, the form of the unitary interaction and the influence of decoherence."

Avoiding rendering views that wouldn't show up in the final picture? They call it LMS:

SMP can be used specifically for VR to achieve what Nvidia calls âLens Matched Shadingâ(TM). The goal of LMS is to avoid rendering pixels which end up being discarded in the final view sent to the display in the VR headset after the distortion process.

How is that not ray tracing?

William Robinson writes: The UDS Project (Ultra Deep Survey), part of UKIRT Infrared Deep Sky Survey, have recently released the final data providing spectacular infrared images of the distant Universe have provided astronomers with the deepest view ever obtained. The UDS mapped a total area four times the size of full moon and detected over 250,000 galaxies, including several hundred observed within the first billion year after Big Bang. This was done since 2005 by observing the same patch of sky repeatedly, obtaining more than 1,000 hours of exposure time and utilizing the power of infrared to provide the deepest view ever obtained over a large area in the sky,
