Submission + - Bill Gates: U.S. Education Harder to Fix Than World Health (xconomy.com)

Submitted by gthuang88
gthuang88 writes: In a Q&A with Harvard students, Bill Gates said his foundation’s work on K-12 education in the U.S. has had little impact, at least compared to its success in reducing infant mortality in developing countries. The challenge with education, he said, is that it is “essentially a social construct” that depends on creating the right culture of accountability and interactions---and funding, of course. Gates said if he had a magic wand for the U.S., he would fix education, and for the rest of the world, nutrition. He also said if he were a college student now, he would study artificial intelligence---and that he was jealous that someone in the room could solve the problem of creating an AI that can read a book and pass an AP exam.

Submission + - How Flying Seriously Messes With Your Mind - And Your Body (bbc.com) 1

Submitted by dryriver
dryriver writes: BBC Future has an interesting piece about how traveling in an airliner does strange things to people's minds and bodies — such as far more people starting to cry while watching even mildly emotional movies on airplanes than is normal, some passengers experiencing decreases in acuity of sight, taste and smell (airline meals are over-seasoned to compensate for this), unusual tiredness or desire to sleep, your skin drying out by up to 37% percent and possibly becoming itchy, and some people breaking wind far more often than they normally would. An excerpt: "There can be no doubt that aircraft cabins are peculiar places for humans to be. They are a weird environment where the air pressure is similar to that atop an 8,000ft-high (2.4km) mountain. The humidity is lower than in some of the world's driest deserts while the air pumped into the cabin is cooled as low as 10C (50F) to whisk away the excess heat generated by all the bodies and electronics onboard. The reduced air pressure on airline flights can reduce the amount of oxygen in passengers’ blood between 6 and 25%, a drop that in hospital would lead many doctors to administer supplementary oxygen. There are some studies, however, that show even relatively mild levels of hypoxia (deficiency in oxygen) can alter our ability to think clearly. At oxygen levels equivalent to altitudes above 12,000ft (3.6km), healthy adults can start to show measurable changes in their memory, their ability to perform calculations and make decisions. This is why the aviation regulations insist that pilots must wear supplementary oxygen if the cabin air pressure is greater than 12,500ft. A study in 2007 showed that after about three hours at the altitudes found in airline cabins, people start to complain about feeling uncomfortable."

Submission + - What to do now that wireless routers have locked firmware/bootloaders? 1

Submitted by thejynxed
thejynxed writes: Awhile ago the FCC in the USA implemented a rule that required manufacturers to restrict end-users from tampering with the radio outputs on wifi routers. It was predicted that manufacturers would take the lazy way out by locking down the firmware/bootloaders of the routers entirely instead of partitioning off access to the radio transmit power and channel ranges. This has apparently proven to be the case, as even now routers that were previously marketed as "Open Source Ready" or "DD-WRT Compatible" are coming with locked firmware. In my case, having noticed this trend, I purchased three routers from Belkin, Buffalo, and Netgear in Canada, the UK, and Germany respectively, instead of the USA, and the results: All three routers had locked firmware/bootloaders, with no downgrade rights and no way to install Tomato, DD-WRT, OpenWRT, etc. It seems the FCC rule is an example of the wide-reaching effect of US law on the products sold in other nations, etc. So, does anyone know a good source of unlocked routers or other technical information on how to bypass this ridiculous outcome of FCC over-reach and manufacturer laziness?

Submission + - Drone Flight Takes to Living Rooms, Gymnasiums, and Parking Garages (hackaday.com)

Submitted by szczys
szczys writes: The FAA can regulate the skies, but they don't own the airspace inside of buildings. There are many ways to get your flying fix indoors. Perhaps the most obvious is flying tiny quadcopters (about 1 inch on each side) in your living room. But for years, hobby groups have formed relationships with schools and churches to have meetups in their gymnasiums. It's not limited to propeller-aircraft; ultralight rubberband power fixed-wing is a popular indoor option. And FPV enthusiasts can get competitive by setting up race courses in parking garages.

Submission + - Mauna Kea protests may end astronomy as we know it

Submitted by StartsWithABang
StartsWithABang writes: If you want to explore the Universe, you need a telescope with good light gathering power, a high-quality camera to make the most out of each photon, and a superior observing location, complete with dark skies, clear nights, and still, high-altitude air. There are only a few places on Earth that have all of these qualities consistently, and perhaps the best one is atop Mauna Kea on Hawaii. Yet generations of wrongs have occurred to create the great telescope complex that's up there today, and astronomers continue to lease the land for far less than it's worth despite violating the original contract. That's astronomy as we know it so far, and perhaps the Mauna Kea protests signal a long awaited end to that.

Submission + - Why CIA is smearing Edward Snowden after Paris attacks (latimes.com)

Submitted by JoeyRox
JoeyRox writes: "Decent people see tragedy and barbarism when viewing a terrorism attack. American politicians and intelligence officials see something else: opportunity. Bodies were still lying in the streets of Paris when CIA operatives began exploiting the resulting fear and anger to advance long-standing political agendas. They and their congressional allies instantly attempted to heap blame for the atrocity not on Islamic State but on several preexisting adversaries: Internet encryption, Silicon Valley's privacy policies and Edward Snowden."

Submission + - Engineers create the blackest material yet (phys.org)

Submitted by schwit1
schwit1 writes: Researchers have created the blackest least reflective material ever made, using as inspiration the scales on the all-white cyphochilus beetle. The result was a an extremely tiny nanoparticle rod resting on an equally tiny nanoparticle sphere (30 nm diameter) which was able to absorb approximately 98 to 99 percent of the light in the spectrum between 400 and 1,400nm, which meant it was able to absorb approximately 26 percent more light than any other known materialâ"and it does so from all angles and polarizations.

Submission + - Will Robot Cabs Unjam the Streets? (theatlantic.com)

Submitted by Anonymous Coward
An anonymous reader writes: The Atlantic has a story with some video of a traffic simulator showing just how the roads can be jammed up by people looking for a place to park. (You can play with the simulator too.) This has been suspected for a long time by many traffic researchers and city planners, but the simulator shows just how quickly the roads jam up after just a few of the blocks fill up with parked cars. The good news is that autonomous cars don't need to park-- they just go give someone else a ride. They could change city life forever.

Submission + - The college majors most likely to marry each other

Submitted by schnell
schnell writes: The blog Priceonomics has published an analysis showing students in which college majors end up marrying another student with that same major. Religious studies (with 21% of students marrying another studying the same field) tops the list among all students, followed by general science. Perhaps unsurprising is that some majors with gender disparities show a high in-major marriage rate among the less represented group — for example, 39% of women engineering majors marry a fellow student in their field, while among men 43% studying nursing and 38% studying elementary education do likewise. The blog concludes that your choice of major may unwittingly decide your choice of spouse, and depending on how well that field is paid, your economic future.

Submission + - Is C++ The Right Tool? 8

Submitted by ranton
ranton writes: I am about to start a personal project which I believe should be done in C/C++. The main reasons I have for this are the needs to manage memory usage and disk access at a very granular level and a desire to be cross-platform. Performance is also important but I am unlikely to spend enough time optimizing to be much faster than core libraries of higher level languages.

On the other hand, network access is also a critical part of the project and I am worried about the effort it takes to make cross platform code for both network and disk access. I have been working in the Java / C# world for the past decade and things like TCP/IP and SSL have just been done for me by core libraries. Do libraries like Boost or Asio do a good job of abstracting these aspects away? Or are there other options for doing granular memory and disk management with more high level languages that have better cross-platform library support? I am willing to brush up on my C/C++ skills if necessary but want to spend as much time as possible developing the unique and potentially innovative parts of my project. Thanks for any advice you can provide.

Submission + - Video Games can Improve Terror Attack Preparedness, even if you don't play them

Submitted by vrml
vrml writes: A study just published by the Computers in Human Behavior journal explores the potential of video games as terror attack preparedness materials for the general public. In the video game that participants tried (screenshots can be seen in the paper), players started a normal day going to a train station and performing actions such as purchasing a ticket and finding a train. Then, they suddenly found themselves in a bombing scenario that they had to survive. In addition to showing that playing the game greatly increased players’ knowledge about preparedness, the study also considered a second group of participants who did not play the game but watched instead a video of the game play. Results indicate that passively watching someone else play the game is as effective as actively playing the game in terms of learning preparedness knowledge. However, they also point out a significant difference concerning psychological effects on threat appraisal: general perception of personal vulnerability to terror attacks and their severity increased more in those who actively played the game rather than those who passively watched game play.

Submission + - Schools That Ban Mobile Phones See Better Academic Results

Submitted by HughPickens.com
HughPickens.com writes: Jamie Doward reports at The Guardian that according to a recent study in the UK, the effect of banning mobile phones from school premises adds up to the equivalent of an extra week’s schooling over a pupil’s academic year with the test scores of students aged 16 improved by 6.4% after schools banned mobile phones, “We found that not only did student achievement improve, but also that low-achieving and low-income students gained the most. We found the impact of banning phones for these students was equivalent to an additional hour a week in school, or to increasing the school year by five days." In the UK, more than 90% of teenagers own a mobile phone; in the US, just under three quarters have one. In a survey conducted in 2001, no school banned mobiles. By 2007, this had risen to 50%, and by 2012 some 98% of schools either did not allow phones on school premises or required them to be handed in at the beginning of the day. But some schools are starting to allow limited use of the devices. New York mayor Bill de Blasio has lifted a 10-year ban on phones on school premises, with the city’s chancellor of schools stating that it would reduce inequality.

The research was carried out at Birmingham, London, Leicester and Manchester schools before and after bans were introduced (PDF). It factored in characteristics such as gender, eligibility for free school meals, special educational needs status and prior educational attainment. “Technological advancements are commonly viewed as increasing productivity,” write Louis-Philippe Beland and Richard Murphy. “Modern technology is used in the classroom to engage students and improve performance. There are, however, potential drawbacks as well, as they could lead to distractions.”

Submission + - New MakerBot CEO Explains Layoffs, Store Closings and the Company's New Vision

Submitted by merbs
merbs writes: MakerBot Industries is the public face of 3D printing. And whenever the public face of a nascent, closely-watched consumer technology undergoes a serious customer relations crisis, closes all of its retail stores, and lays off 20 percent of its staff, the impact is prone to ripple beyond the fate of a single company. Jonathan Jaglom, in other words, may be tasked not just with reversing the fortunes of MakerBot, where he’s just been appointed CEO, but an entire industry.
