Standardized Laptop Charger Approved By IEC

Sockatume writes “The IEC, the standards body which wrote the phone charger specification used in the EU, has approved a standardised laptop charger. While the ‘DC Power Supply for Portable Personal Computer’ doesn’t have a legal mandate behind it, the IEC is still optimistic that it will lead to a reduction in electronics waste and make it easier to find a replacement charger. Unfortunately the technical documentation does not seem to be available yet, but previous comments indicate that it will be a barrel plug of some kind.” I wish they’d push a yank-resistant and positive-connecting plug along the lines of Apple’s MagSafe.

Inside the Massive 2014 Winter Olympics WiFi Network

alphadogg writes “Engineers are putting the final touches on a network capable of handling up to 54Tbps of traffic when the Winter Olympics opens on Feb. 7 in the Russian city of Sochi. The two locations where the Olympics will take place — the Olympic village in Sochi and a tight cluster of Alpine venues in the nearby Krasnaya Polyana Mountains — are completely new construction, so this project represents a greenfield environment for Avaya, the company heading up the project. In addition to investing in a telecom infrastructure, Russia is spending billions of dollars to upgrade Sochi’s electric power grid, its transportation system and even its sewage treatment facilities.” Read more of this story at Slashdot.

US Light Bulb Phase-Out’s Next Step Begins Next Month

SonicSpike writes “Light bulb manufacturers will cease making traditional 40 and 60-watt light bulbs — the most popular in the country — at the start of 2014. This comes after the controversial phasing out of incandescent 75 and 100-watt light bulbs at the beginning of 2013. In their place will be halogen bulbs, compact fluorescent bulbs, LED bulbs and high efficiency incandescents — which are just regular incandescents that have the filament wrapped in gas. All are significantly more expensive than traditional light bulbs, but offer significant energy and costs savings over the long run. (Some specialty incandescents — such as three-way bulbs — will still be available.) … The rules were signed into law by President George W. Bush in 2007. They are designed to address gross inefficiencies with old light bulbs — only 10% of the energy they use is converted into light, according to the Environmental Protection Agency, which has a handy fact sheet about the changes. The rest is wasted as heat. But the rules have drawn fire from a number of circles — mainly conservatives and libertarians who are unhappy about the government telling people what light bulbs they can use. They argue that if the new ones really are so good, people will buy them on their own without being forced to do so.” Read more of this story at Slashdot.

Photos Stream Back From China’s Lunar Lander

After the successful soft landing of its carrier vessel on the surface of the moon, China’s Jade Rabbit lunar rover has begun beaming back photos of the lunar surface. From the BBC’s article, with links to video as well as several photos, comes this description: “Chang’e-3 is the third unmanned rover mission to touch down on the lunar surface, and the first to go there in more than 40 years. The last was an 840kg (1, 900lb) Soviet vehicle known as Lunokhod-2, which was kept warm by polonium-210. But the six-wheeled Chinese vehicle carries a more sophisticated payload, including ground-penetrating radar which will gather measurements of the lunar soil and crust. The 120kg (260lb) Jade Rabbit rover can reportedly climb slopes of up to 30 degrees and travel at 200m (660ft) per hour. … The rover and lander are powered by solar panels but some sources suggest they also carry radioisotope heating units (RHUs), containing plutonium-238 to keep them warm during the cold lunar night. According to Chinese space scientists, the mission is designed to test new technologies, gather scientific data and build intellectual expertise. It will also scout valuable mineral resources that could one day be mined.” Read more of this story at Slashdot.

‘Darkness Ray’ Beams Invisibility From a Distance

KentuckyFC writes “Optical engineers generally build imaging systems with the best possible resolving power. The basic idea is that an imaging system focuses light into a pattern known as a point spreading function. This consists of a central region of high intensity surrounded by a concentric lobe of lower intensity light. The trick to improving resolution is narrowing and intensifying this central region while suppressing the outer lobe. Now optical engineers have turned this approach on its head by suppressing the central region so that the field intensity here is zero while intensifying the lobe. The result is a three-dimensional beam of darkness that hides any object inside it. The engineers say this region can be huge — up to 8 orders of magnitude bigger than the wavelength of the imaging light. What’s more, the optics required to create it are simple and cheap: a lens consisting of concentric dielectric grooves. The team has even tested a prototype capable of hiding a 40-micrometre object in visible laser light.” Read more of this story at Slashdot.

More Students Learn CS In 3 Days Than Past 100 Years

theodp writes “Code.org, backed by Bill Gates and Mark Zuckerberg, boasts in a blog post that thanks to this week’s Hour of Code, which featured a Blockly tutorial narrated by Gates and Zuckerberg, ‘More students have participated in computer science in U.S. schools in the last three days than in the last 100 years.’ Taking note of the impressive numbers being put up on the Hour of Code Leaderboards (’12, 522, 015 students have done the Hour of Code and written 406, 022, 512 lines of code’), the Seattle Times adds that ‘More African American and Hispanic kids learned about the subject in two days than in the entire history of computer science, ‘ and reports that the cities of Chicago and New York have engaged Code.org to offer CS classes in their schools. So, isn’t it a tad hyperbolic to get so excited over kids programming with blocks? ‘Yes, we can all agree that this week’s big Hour of Code initiative is a publicity stunt, ‘ writes the Mercury News’ Mike Cassidy, ‘but you know what? A publicity stunt is exactly what we need.'” Read more of this story at Slashdot.

Ford Self-Driving R&D Car Tells Small Animal From Paper Bag At 200 Ft.

cartechboy writes “Autonomous driving is every car manufacturer’s immediate R&D project. In car-building terms, even if a new technology isn’t due for 10 years — since that’s just two full vehicle generations away– it has to be developed now. So now it is for autonomous car research and testing, and this week Ford revealed a brand new Fusion Hybrid research vehicle built for autonomous R&D with some interesting tech capabilities. Technologies inside the new Fusion Hybrid research vehicle include LIDAR (a light-based range detection), which scans at 2.5 million times per second to create a 3D map of the surrounding environment at a radius of 200 feet. Ford says the research vehicle’s sensors are sensitive enough to detect the difference between a small animal and a paper bag even at maximum range. More road-ready differentiations include observation and understanding of pedestrians, cyclists, and plain old stationary objects. Ford is working on this project in cooperation with the University of Michigan.” Read more of this story at Slashdot.

Engineering the Perfect Coffee Mug

Nerval’s Lobster writes “From the annals of Really Important Science comes word that a research assistant who picked up his B.S. just seven months ago has invented a coffee mug designed to keep java at just the right piping-hot temperature for hours. Logan Maxwell, who got his undergraduate degree in chemical engineering from North Carolina State University in May, created the “Temperfect” mug as part of his senior design project for the College of Engineering. Most insulated mugs have two walls separated by a soft vacuum that insulates the temperature of a liquid inside from the temperature of the air outside. Maxwell’s design has a third layer of insulation in a third wall wrapped around the inner basin of the mug. Inside is a chemical insulator that is solid at room temperature but melts into a liquid at 140 degrees Fahrenheit. The insulator – which Maxwell won’t identify but swears is non-toxic – turns to liquid as it absorbs the extra heat of coffee poured into the mug at temperatures higher than 140 F, cooling it to a drinkable temperature quickly. As the heat of the coffee escapes, the insulating material releases heat through the inner wall of the mug to keep it hot as long as possible; a graph mapping the performance of a prototype shows it could keep a cup of coffee at between 128 F and 145 F for as long as 90 minutes. “Phase-change” coffee-mug insulation was patented during the 1960s, but has never been marketed because they are difficult and expensive to manufacture compared to simpler forms of insulation. While working on the Temperfect design, Maxwell met Belgian-born industrial designer Dean Verhoeven, president of consulting form Ancona Research, Inc., who had been working on a similar design and had already worked out how to manufacture a three-walled insulated mug cost effectively. The two co-founded a company called Joevo to manufacture the mugs.” According to the Joevo Kickstarter page, you can get one starting at $40. For that much, I’d like a clever lid like this Contigo has. Read more of this story at Slashdot.

Cybercrime Marketplace Mastermind Faces 18 Years In Prison

wiredmikey writes “A Ukrainian national, Roman Vega, who pleaded guilty in 2009 to creating a popular online marketplace for selling stolen financial account data has been sentenced to 18 years in prison. Called one of the world’s ‘most prolific cybercriminals’ by the Department of Justice, Vega, 49, will serve significant time in prison for his role in co-founding the notorious website CarderPlanet. In the early 2000s, Vega co-founded and became a high-ranking administrator of the notorious website, which became one of the first and busiest online marketplaces for the sale of stolen financial information, computer hacking services and money laundering. At its height, CarderPlanet had more than 6, 000 members and had a hierarchical leadership structure that borrowed its leadership titles from La Cosa Nostra, US authorities said.” Read more of this story at Slashdot.
