+ - Sound scientific thinking finds a cleaner way to extinguish fires->

Submitted by SternisheFan
SternisheFan (2529412) writes "It happens so quickly you almost don’t believe it: Seth Robertson and Viet Tran ignite a fire, snap on their low-rumbling bass frequency generator and extinguish the flames in seconds. And even after you’ve seen it over and over, it’s still unbelievable.

But the two last-year engineering majors at George Mason University, in Fairfax, Virginia, appear to have invented a way to use sound waves to put out fires. It started as an idea for a research project, and after a year of trial and error and spending about $600 of their own money, they have built a somewhat portable sound generator, amplifier, power source and focusing tube that would seem to have great potential in attacking fires in a variety of situations.

Robertson, 23, and Tran, 28, applied for a provisional patent at the end of November, which gives them a year to do further testing on other flammable chemicals – so far they have put out only fires started with rubbing alcohol – and to continue to refine their device. Although they originally conceived of the device as a way to put out kitchen fires and, perhaps, fires in spacecraft, a local fire department already has asked them to test their bass waves on a structure fire; they think the concept could replace the toxic chemicals involved in fire extinguishers.
  But how does it work? The basic concept, Tran said, is that sound waves are also “pressure waves, and they displace some of the oxygen” as they travel through the air. Oxygen, we all recall from high school chemistry, fuels fire. At a certain frequency, the sound waves “separate the oxygen from the fuel. The pressure wave is going back and forth, and that agitates where the air is. That specific space is enough to keep the fire from reigniting.”"

It does exactly what it says on the tin" was originally an advertising slogan in the United Kingdom, which then became a common idiomatic phrase.[1][2] It colloquially means anything that is as it appears or claims to be without further explanation needed. It originated in a series of television advertisements by the woodstain and wood-dye manufacturer Ronseal, initiated in 1994 and still being broadcast as of 2013.[3] The phrase originated from a winning entry to a competition run by Polycell. The winner Mrs Ailsie Allen coined the phrase " it does what it says". http://en.wikipedia.org/wiki/D...

Radio Shack remained stuck in the '80s and '90s as cooler, cheaper options like Best Buy and Amazon took center stage. The store failed to keep up with fast and furious technological advances, and didn't adapt to consumers' ever-changing needs. http://www.huffingtonpost.com/...

+ - Arkansas is Now the First State to Require That High Schools Teach Coding->

Submitted by SternisheFan
SternisheFan (2529412) writes "Arkansas will be implementing a new law that requires public high schools to offer classes in computer science starting in the 2015-16 school year. Arkansas Gov. Asa Hutchinson, who signed the bill, believes it will provide “a workforce that’s sure to attract businesses and jobs” to the state.

$5 million of the governor’s proposed budget will go towards this new program. For the districts incapable of of administering these classes due to lack of space or qualified teachers, the law has provisions for online courses to be offered through Virtual Arkansas.

Although students will not be required to take computer science classes, the governor’s goal is to give students the opportunity if they “want to take it”.

Presently, only one in 10 schools nationwide offer computer science classes. Not only will Arkansas teach these classes in every public high school and charter school serving upper grades, the courses will count towards the state’s math graduation requirement as a further incentive for students .

Training programs for teacher preparation will be available, but with the majority of the infrastructure already primed, the execution of this new law should hopefully be painless and seamless."

"How do you sell something nobody actually needs?" That's where advertising comes in. The whole point of dvertising is to get people to buy things that they don't really need, and to "sell happiness". To convince us that if we bought and owned (insert Product here), we'd feel happy about ourselves.

...Nobody buys this OS because of the App Store. but there are a lot of other good reasons to use it.

To be fair, the app store does have a kickass free pinball game. :-)

With Classic Shell 8.1 works fine for me. A much stabler OS, updates install with no issues. I can't see myself needing Cortana, if 10 doesn't allow Classic Shell, free upgrade or not, I'll stick with what I know works for me.

+ - Robocops Direct Traffic in the Congo->

Submitted by mspohr
mspohr (589790) writes "The Guardian describes robocops used in Kinshasa to direct traffic:
"The solar-powered aluminium robots are huge, towering over the jammed streets of Kinshasa, as cars and motorcyles jostle for road room, their horns blasting.
Each hand on the odd-looking machines — built to withstand the year-round hot climate — is fitted with green and red lights that regulate the flow of traffic in the sprawling city of nine million.
The robots are also equipped with rotating chests and surveillance cameras that record the flow of traffic and send real-time images to the police station."
These are second generation robots designed by a Congolese association of women engineers.
"Although the humanoids look more like giant toys than real policemen, motorists have given them a thumbs up.
“There are certain drivers who don’t respect the traffic police. But with the robot it will be different. We should respect the robot,” taxi driver Poro Zidane told AFP.""
