Hrm, it seems I would be wrong.

The reaction product is a liquid made from longchain hydrocarbon compounds, known as blue crude.

So methane is out, although I imagine they get a whole mixture of variously chained hydrocarbons since the graphic talks about using a refinery to split out diesel.

+ - Ames Labortory scientists create cheaper magnetic material->

Submitted by Anonymous Coward
An anonymous reader writes: Karl A. Gschneidner and fellow scientists at the U.S. Department of Energy’s Ames Laboratory have created a new magnetic alloy that is an alternative to traditional rare-earth permanent magnets.

The new alloy—a potential replacement for high-performance permanent magnets found in automobile engines and wind turbines--eliminates the use of one of the scarcest and costliest rare earth elements, dysprosium, and instead uses cerium, the most abundant rare earth.

The result, an alloy of neodymium, iron and boron co-doped with cerium and cobalt, is a less expensive material with properties that are competitive with traditional sintered magnets containing dysprosium.

Yes, it does use the water, and yes, you get it back later. The water is split into H2 and O, then 4H2 are used to make CH4. When CH4 is burned in 2O2, you get CO2 + 2H2O. The same applies when they take their "Blue Crude" (very likely methane) and turn it into a longer-chained hydrocarbon.

+ - Using Smartphones for Contactless Sleep Apnea Diagnosis->

Submitted by techamaze
techamaze writes: The gold standard for diagnosing sleep apnea — a disease which affects roughly 1 in 13 Americans — requires an overnight hospital stay and costs thousands of dollars. The patient sleeps in a strange bed, gets hooked up to a tangle of wires and undergoes an intensive polysomnography test to count how many times a night he or she struggles to breathe.

By contrast, a new app developed at the University of Washington uses a smartphone to wirelessly test for sleep apnea events in a person’s own bedroom. To determine if a person is experiencing sleep apnea events, ApneaApp transforms an Android smartphone phone into an active sonar system that tracks tiny changes in a person’s breathing movements. The phone’s speaker sends out inaudible sound waves, which bounce off a sleeping person’s body and are picked back up by the phone’s microphone.

The clinical study tested ApneaApp on 37 patients undergoing sleep studies at Harborview Medical Center because of apnea concerns. Researchers put a Samsung Galaxy S4 smartphone on a corner of the bed during the overnight sleep study. During nearly 300 hours of testing, the app tracked various respiratory events including central apnea, obstructive apnea and hypopnea with between 95 and 99 percent accuracy, compared to intensive polysomnography.

“Right now we don’t have enough sleep clinics, sleep laboratories and sleep specialists in the country to address all the sleep apnea that is out there,” said co-author Dr. Nathaniel F. Watson, professor of neurology and co-director of the UW Medicine Sleep Center.

+ - Imagination to Release Open MIPS Design to Academia->

Submitted by DeviceGuru
DeviceGuru writes: Imagination Technologies has developed a Linux-ready academic version of its 32-bit MIPS architecture MicroAptiv processor design, and is giving it away free to universities for use in computer research and education. As the MIPSfpga name suggests, the production-quality RTL (register transfer level) design abstraction is intended to run on industry standard FPGAs. Although MIPSfpga is available as a fully visible RTL design, MIPSfpga is not fully open source, according to the announcement from Robert Owen, Manager of Imagination’s University Programme. Academic users can use and modify MIPSfpga as they wish, but cannot build it into silicon. 'If you modify it, you must talk to us first if you wish to patent the changes,' writes Owen.

+ - First open ranking of Wikipedia based on Wikimedia available 1

vigna writes: The Laboratory for Web Algorithmics of the Università degli studi di Milano did it again: after creating the first open ranking of the World Wide Web they have put together the first entirely open ranking of Wikipedia, using Wikidata to categorize pages. The ranking is based on classic and easily explainable centrality measures or page views, and it is entirely open — all data (Wikipedia and Wikidata dumps) and all software used is publicly available. Just in case you wonder, the most important food is chocolate, the most important band are the Beatles and the most important idea is atheism.

I tried putting in "yourgut!" for my most recent password, and it failed the security check for not having a capital letter or a number. What kind of lousy password suggestions are you peddling?!

Instead, I went with "Yourgut1!" and now it tells me that it's Highly Secure.

Identity is a capability. What do you ask someone to do? Identify themselves. How do they do it? By providing a piece of information you know to be known to them, either by fact of being born attached to it, or by fact of regurgitating it somehow.

All the bank needs is assurance that you're the only one likely to possess it, short of dedicated efforts to illicitly acquire it. Assurance is not a black and white thing, settled once and for all; it's a bar you have to jump over. That's the whole idea of security.

How big is a 55 gallon drum? About the size of a bathtub? Asked Google, and it told me:

Many drums have a common nominal volume of 208 litres (55 US gal; 46 imp gal) and nominally measure just under 880 millimetres (35 in) tall with a diameter just under 610 millimetres (24 in) and differ by holding about thirteen gallons more than a barrel of crude oil.

178 gallons / 55 gallons/drum ~= 3.24 drums

How big is a bathtub?

The capacity of an average, US, standard run-of-the-mill built in bathtub filled up to the very bottom of the overflow, which is as full as you can get it is approx. 42 gallons

Let me clarify. All the standard size American Standard tubs are 42 gallons. I also went to the Kohler site and they are the same.

178 gallons / 42 gallons/bathtub ~= 4.24 bathtubs

Indeed, you missed the first two paragraphs of the FA.

TOPEKA, Kan. — A 20-year-old man was arrested Friday while trying to arm what he thought was a 1,000-pound bomb near a Kansas military base as part of a plot to support the Islamic State group, federal prosecutors said.

John T. Booker Jr. is accused of planning a suicide attack at Fort Riley, about 70 miles west of Topeka. Prosecutors allege he told an FBI informant he wanted to kill Americans and engage in violent jihad on behalf of the terrorist group, and said he believed such an attack was justified because the Quran "says to kill your enemies wherever they are," according to a criminal complaint.

/yes, I know, nobody reads TFA

One can't proceed from the informal to the formal by formal means.
