Bamboo like Crystals Help Tiny Chip Wires Keep Shrinking

mimin

December 26, 2015

When it comes to talk of the end of Moore’s Law, transistors attract much of the attention. But the kilometers of copper wires that connect these devices on each chip have miniaturization problems of their own.

Now it seems the issue might not be as bad as engineers once thought. A team based at IBM and GlobalFoundries examined wires that will be needed for chips after the arrival of the 7-nanometer node, a manufacturing stage expected in three or so years. They found indications of a crystal structure that might actually help speed signals and reduce energy consumption.

The boost comes in resistivity, a measure of how strongly a material opposes the flow of current. Copper has a very low intrinsic resistivity. But this “bulk property” breaks down in small wires. Electrons bump up against side walls and scatter off grain boundaries, the planar surfaces inside the wire where a copper crystal changes its orientation.

The problem is only expected to get worse as copper wiring shrinks further. Adam Pyzyna of IBM’s Thomas J. Watson Research Center, in Yorktown Heights, N.Y., and his colleagues tested a variety of wire sizes and shapes. Intriguingly, for certain geometries,

Five Reasons to Upgrade to the iPad Mini with Retina Display

mimin

December 21, 2015

The Apple iPads have revolutionized the way people use tablets at home, at work, in school, and while on the go. These devices are powerful communication, productivity, and organizational tools that can be fully customized to handle a very wide range of needs.

Meanwhile, just a few years ago, the idea of a notebook computer that weighed less than 8 to 10 pounds was unheard of, and a tablet was simply considered to be a gadget for geeks instead of to a viable computing device that could replace the need for a notebook computer altogether.

Today, when we look at mobile devices, notebook computers, or tablets that weigh more than 1 or 2 pounds are considered too heavy and cumbersome. In fact, we’re being spoiled by powerful technology that’s literally at our fingertips whenever and wherever we want it to be.

For example, the full-size iPads, with their 9.7-inch (diagonal) displays, now weigh about 1 pound and have a battery that lasts upwards of 10 hours. For some people, the size and weight of even the latest iPad Air is too large and heavy.

Car Camera Network Could Produce Virtual Maps of Pedestrians

mimin

December 14, 2015

A growing fleet of smart cars may add their street camera views to those of the surveillance camera networks already covering many major cities. That could open the door for a new technology that enables different video cameras to “talk” with one another and track the same individual person across many different camera views—possibly giving rise to Google Earth style maps that can display pedestrian and vehicle traffic.

The technology is based on a computer algorithm that can compare different camera views of the same person and learn to recognize the same individuals across many camera views by focusing on body color, texture and movement. Researchers envision a large-scale version of the system tracking pedestrian traffic on a virtual map—perhaps displayed on a car’s GPS screen—or enabling police to easily track fleeing suspects across multiple surveillance camera views.

“Our idea is to enable the dynamic visualization of the realistic situation of humans walking on the road and sidewalks, so eventually people can see the animated version of the real-time dynamics of city streets on a platform like Google Earth,” said Jenq-Neng Hwang, a professor of electrical engineering at the University of Washington, in a news release.

Hwang’s team of researchers tested the algorithm with cameras placed on moving cars. They

Metasurface Optics for Better Cellphone Cameras and 3D Displays

mimin

November 22, 2015

Engineers at the California Institute of Technology have created a metasurface out of tiny pillars of silicon that act as waveguides for light. The way they arrange the pillars allows them to control the phase of light passing through the surface; this ability gives them control over how the light is focused, as well as its polarization, which is important for uses such as liquid crystal displays and 3-D glasses. Metasurfaces are structured planes so thin that they count as being two-dimensional; their periodic designs manipulate light in unusual ways.

“We’re trying to create kind of a new platform for optics,” says Amir Arbabi, a postdoc in Andrei Faraon’s Nanoscale and Quantum Optics Lab. The team described their work in the latest issue of Nature Nanotechnology.

The silicon pillars have to be somewhat shorter than the wavelength of light they’re designed to manipulate. In the case of the metasurface described in the paper, the pillars are 715 nanometers tall, to handle infrared light with a wavelength of 915 nm. But they could easily be made shorter for visible light, Arbabi says. The pillars range in diameter from 65 to 455 nm, and they’re elliptical in shape. The ellipses are not all oriented

Whats So Hot About Snapchat

November 15, 2015

Have you ever taken and shared a photo or video that you later regretted? Sent an embarrassing photo that your close friends might appreciate to your co-workers or family who didn’t appreciate it at all? Had an old social network post you made years ago come back to haunt you?

Then you’ll appreciate Snapchat, the photo and video sharing app that’s a ton more private than Instagram, Facebook, or Twitter. Unlike those other social networks, Snapchat doesn’t offer any public sharing or searching; your “snaps” go directly to the individuals you specify, and to no one else. The general public cannot find your snaps by browsing or searching, they’re truly private. And, even better, they disappear 10 seconds after viewing, so not even your friends can keep a copy to embarrass you later.

What Is Snapchat?

Snapchat is a unique and popular mobile app that lets users share digital photos and videos with friends—and then have those photos and videos disappear, forever. The Snapchat app is available for both iOS and Android devices.

First of all, Snapchat is a mobile app. There’s no website to speak of, and no way to use it on your desktop or notebook computer. It’s an app that

Anonabox Promises Total Online Anonymity Thats Easy Open Source and Cheap

November 11, 2015

Nobody likes giving up their privacy. But as much as we complain about it, relatively few of us are willing to put time, money, or effort into consistently protecting our privacy online. And it’s not like it’s that hard, relatively speaking: the Tor Project offers excellent, free software that lets you browse the Internet in complete anonymity, if you use it properly. With Tor, data you send over the Internet are encrypted and stripped of any identifying information (namely, your IP address) before reaching their destination. It’s one of the most reliable methods that you can use to protect your identity online. However, it does take some amount of experience to use, along with a conscious decision to choose security over convenience. If that sounds like too much work (and it sure sounds like a lot of work, doesn’t it?), the Anonabox could be exactly what you need.

The Anonabox, now on Kickstarter, is a tiny little networking tool that will sit there and invisibly do all of the Tor-related stuff that you’d want it to do, without you ever having to think about it.

What We Can Expect from iOS 8

mimin

November 2, 2015

Last year, when Apple first started showing off iOS 7, it looked drastically different from iOS 6. Not only were users introduced to many new features that were never before possible using an iPhone or iPad, but the apps and interface offered by their smartphone or tablet dramatically changed.

Now, about one year later, Apple has begun offering previews of iOS 8. This new version of the operating system retains the same overall appearance as iOS 7 from a visual design and user interface standpoint. However, this operating system update does once again introduce a wide range of new features, functions and apps that will expand the ways people can interact with and use their iPhone or iPad in their everyday lives.

One of the more obvious improvements an iPhone or iPad user will discover is the enhanced virtual keyboard. Now, instead of simply using the AutoCorrect feature to automatically correct what the mobile device perceives as typos, the virtual keyboard will predict what you’re trying to say, and actually suggest the next word even before you begin typing it. Whether you’re composing text messages or emails, the new QuickType virtual keyboards will determine who you’re communicating with and select

Do Computers Die Of Old Age?

October 27, 2015

Nothing lasts forever, not even electronics. “People assume electronic components will not age,” says Bianca Schroeder, a computer scientist at the University of Toronto. Without moving parts, electronics seem unlikely to wear out. Yet even a standard memory module comprising little more than a capacitor and a transistor can begin to dodder. “It’s kind of surprising, but most of the computer components I look at show signs of aging,” Schroeder says.

Still, system-reliability experts know relatively little about components’ life spans in the wild. “We don’t have much data,” Schroeder admits. “People usually don’t run their computers long enough to find out if they die.” Not to mention, manufacturers don’t like to publish failure rates from their in-house product tests, and according to Schroeder, “they have no knowledge of how these components behave in the field.” Lab testing environments rarely match the physical jostling, temperature swings, and dust accumulation of the real world.

A few facts are known. In 2014, software engineer Brian Beach put out reliability stats for Backblaze, a data-storage company that runs 35,000 disk drives at all times. He found that about 5 percent of the firm’s disks fail in their first 18 months, most likely

Scientists Want To Use Drones To Capture Whale Snot

mimin

October 23, 2015

Whales are awesome and important. But because they are so big and sensitive to sound, researchers have a hard time collecting all the data they need without freaking them out. Now, whale biologists from the nonprofit Ocean Alliance have teamed up with students from the Olin College of Engineering to create drones that can capture one of the most important biological materials–a whale’s snot–without disturbing the animals. They’ve launched a Kickstarter campaign to help fund their research.

Whale “blow” is the combination of mucus, or snot, water, and tissue that may sound very gross, but is essential for whale biologists–from it, they can tell if the whales are stressed or pregnant based on their hormones, check their snot to see if they are infected with any viruses, or gather tissue samples for DNA analysis.

Normally, the process to collect whale blow requires the researchers to travel next to the whales in boats and extend a 10 foot-long pole over the blowhole in the hope of capturing some of the ejected substance. This is very annoying and disruptive to the whales, as the researchers note in their Kickstarter video in which they harass Sir Patrick Stewart, a friend of

Tips to Show Your IT Skills on Your Technology Resume

mimin

October 2, 2015

Employers often screen candidates based on their technical skills, so technology job seekers naturally want to make sure they present their skills properly. As a result, creating the skills section of a technology resume section can be a challenge.

Typical resume issues technology professionals wrestle with include:

Whether to list skills alphabetically or in order of importance.
Whether to include every skill and how much detail to provide.
How to differentiate between expert knowledge of a technology with passing familiarity.

Don’t Exaggerate

One recruiter’s advice is simple: Don’t obsess over the skills section to the point of embellishment. “In adding a skills section to their resume, a lot of people have a tendency to exaggerate their level of expertise in various technologies,” says Scott Hajer, senior corporate recruiter for Software Architects. “They figure the more keywords, the more exposure.”

Such tactics are likely to backfire, especially during a technology job interview. “We had a candidate who had a big grid on his resume, listing all the skills he had and rating himself on a scale of 1 to 5 in them,” says Hajer. One of the skills was J2EE, with a “3” (for average ability) tagged to it. “When asked to talk about J2EE, he could not

October 2, 2015

Learning the ins and outs of the latest technology is a lot like learning to swim or ride a bike: The younger you are, indexzzzzzz the more naturally it comes. This is troubling news for parents who already feel two steps behind their digitally savvy children.

While assisting with traditional school work poses enough challenges, parents now need to help their children build wikis and solve math problems on iPad apps. As schools shift toward online platforms and E-learning devices, tech-challenged parents may feel intimidated.

The good news is that keeping up with the digital pace is as simple as starting a conversation, says Monica Vila, founder and “chief technology mom” of The Online Mom, a website focused on helping parents embrace technology. “You’re never behind the curve as a parent completely if you’re involved,” Vila says.

Vila and other tech-savvy parents and educators offer some advice to keep up with your child’s technology, while also keeping your family safe from digital traps.

1. Show and tell: If your child is using a device, program, or website you aren’t familiar with, have them show you how it works.

6 Tips for Technology Implementations at Small Schools

September 22, 2015

Small universities have fewer resources and fewer employees, and they can’t afford to spend as much money on technology as their larger counterparts. Brad Marcum, director of academic data services at the University of Pikeville – Kentucky College of Osteopathic Medicine, provides six tips to level the technology-implementation playing field for smaller schools.

For years, Staples, the office supply chain, used an advertising campaign featuring the “easy button.” While we all wish this button actually existed, most know that implementing new technology processes isn’t easy — especially for smaller educational programs. Small universities have fewer resources and fewer employees, and they can’t afford to spend as much money on technology as their larger counterparts. With a smaller margin for error, small schools need to make the best decisions possible when selecting technologies that can help them better educate their students.

In the past year, the University of Pikeville — College of Osteopathic Medicine (KYCOM) began a process to purchase two software programs to help us better access our program. One is in place and has been a huge success for our small program. The other is about to go live. In the past, we did not think that we could afford such programs.

Millennials will take a hefty pay cut for a job in tech

September 12, 2015

Looking at the salaries in the tech world, it would be easy to make the assumption that some of the workers are only in it for the money. But as a recent survey from Progressive Insurance makes clear, that couldn’t be further from the truth for millennials pursuing a career in IT.

According to the report, which took data from 1,000 US millennials interested in tech jobs, 81% said they would accept a reduced compensation package if it meant they’d be able to do a job they truly loved.

Not only that—they’re willing to travel to do it. A total of 82% of millennials interested in IT said that they would relocate an average of more than 600 miles for the right job offer.

Increasingly, that means a job that offers flexible working arrangements, like the ability to work from home. In fact, 58% of the respondents said that they’d rather take a job that lets them work remotely than one that pays 20% more.

“By and large what we found is that millennials interested in IT want a job that allows them flexibility and growth opportunities, and which inspires them,” said Lynley Williams, recruiting director for Progressive Insurance.

Amazon launches gaming and 4K streaming Fire TV update

September 4, 2015

Amazon is moving into 4K content with a new Fire TV box and ultra-high definition content through its video streaming service.

The new Fire TV builds on the success of last year’s streaming media box, which Amazon claims has been the best selling box on the market in the UK and Germany, beating Apple TV among others.

Amazon is bullish in the face of Apple’s new box, claiming the new Fire TV is 75% faster, handles 4K content, and has a more efficient compression system for full HD content that will allow twice as many of its customers to stream 1080p video over poor broadband connections than the number who currently can.

All of Amazon’s original TV series will be available in 4K, as will American TV shows such as Breaking Bad and hundreds of recent movies. Rival service Netflix, which also has a library of 4K content, will be available in ultra HD on the new Fire TV. Connection speeds of at least 15Mbps will be required for 4K content.

Streaming media will also use what Amazon calls “ASAP”, which predicts what users are likely to want to see and caches a portion of the show or movie on the device in

Facebook To Add Dislike Button Video Chat

mimin

September 2, 2015

If today’s Townhall Q&A with Facebook CEO Mark Zuckerberg is any indication, we can soon expect some big changes in our Internet lives, both on and off Facebook.

“I think people have asked about the dislike button for many years,” Zuckerberg said. “Today is a special day because today is the day I can say we’re working on it and shipping it.”

He went on to explain that the reasoning behind the new Facebook function is to provide users with an appropriate public response to uncomfortable news. “What they really want is the ability to express empathy. Not every moment is a good moment,” he said.

Reflecting the nuance in emotion, the so-called ‘dislike’ button will give users an as-of-yet unknown alternative to ‘like’ when it is revealed to the world.

Another development in the works is the much-anticipated video chat in Facebook Messenger, which spells a potential disturbance in the face-to-face chatting ecosystem currently dominated by Skype and Apple’s FaceTime.

Artificial Intelligence Is Taking Computer Chess Beyond Brute Force

mimin

August 25, 2015

Chess is often seen as the ultimate mental challenge: 32 pieces on an 8-by-8 board, and nearly limitless possible moves. There are chess engines that calculate millions of moves per second, but the traditional approach is to “brute force” the match. Brute forcing is a method in hacking (and apparently computer chess simulation) that means to run every possibility of a problem until the program finds the best solution.

But Matthew Lai wants to make chess-playing computers smarter. For part of his Masters degree at Imperial College London, Lai trained artificial neural networks to play at the level of a FIDE International Master, better than 97.8 percent of rated tournament players. He calls his software Giraffe.

After 72 hours of training, Giraffe figured out the best possible move 46 percent of the time. The move that Giraffe selected was in the top 3 moves 70 percent of the time. Previous attempts at machine learning in chess, like Knightcap, needed programmers to design “pattern recognizers,” separate functions to learn moves like shielding a king with a pawn, or the importance of having both colors of a bishop, says Lai. The machine learning algorithm would watch already-defined moves, and learn

Robots Are Coming For The Garbagemans Job

mimin

August 24, 2015

As long as there are humans, there will be garbage. And, for a long time, it seemed inevitable that there would always be garbagemen, too, to collect that refuse. A new project by carmaker Volvo, recycling company Renova, Sweden’s Chalmers University of Technology and Mälardalen University, and Penn State University wants to create robot assistants for garbage trucks. With automation, a human driver can stick to the road, and a robot can do the literal heavy lifting.

Dubbed Robot-based Autonomous Refuse handling, or ROAR, the project will feature a robot designed by Mälardalen University, control system designed by Chalmers University, and a control panel designed by Penn State. Combined, these efforts will hopefully yield a robot that can grab trash and toss it on board a Renova waste truck by June 2016.

Volvo’s release on the matter suggests the purpose behind ROAR is a system that collects garbage “without waking the sleeping families and without heavy lifting for the refuse truck’s driver,” but there’s little evidence yet that humanoid robots or quieter or more graceful than actual humans. In terms of cost, robots can certainly be cheaper than people, if the same already-employed driver is now also responsible

These Speakers Use Ultrasonic Waves To Cut Through The Noise

mimin

August 11, 2015

Problem

Everyday speakers—whether they’re in a cellphone, TV, or radio—scatter sound waves as soon as they leave the cone. A single wave can bounce off dozens of surfaces, slamming into other signals and degrading along the way, before reaching your ear in a muddled mess. Adding to this audio chaos, most midrange TVs only emit sound from rear or downward-facing speakers. So turning them up just doesn’t help. Gamers and TV obsessives often turn to soundbars and directional speakers for relief, but even those don’t offer a true high-fidelity fix.

Solution

HyperSound Clear speakers aim sound waves directly at a listener using a tightly focused beam. It uses ultrasonic waves, which don’t disperse as quickly or easily as standard sound waves. Embedded in that signal is high-fidelity audio with zero disruption. That means a movie’s epic surround sound can be directed straight at your ear—just like a laser. HyperSound speakers were designed for the hearing impaired, and like hearing aids, they must be tuned by a doctor. However, in 2014, gaming audio giant Turtle Beach merged with HyperSound’s parent company, raising hopes in the gaming world that laser-focused high-fidelity will be coming to Cheetos-crusted couches one day soon.

Tech Tips for the Basic Computer User

August 2, 2015

Last week, I wrote an entry on my blog that began like this:

“One of these days, I’m going to write a book called, ‘The Basics.’ It’s going to be a compendium of the essential tech bits that you just assume everyone knows–but you’re wrong.

“(I’ll never forget watching a book editor at a publishing house painstakingly drag across a word in a word processor to select it. After 10 minutes of this, I couldn’t stand it. ‘Why don’t you just double-click the word?’ She had no clue you could do that!)”

Many readers chimed in with other “basics” that they assumed every computer user knew–but soon discovered that what’s common knowledge isn’t the same as universal knowledge.

I’m sure the basics could fill a book, but here are a few to get you started. All of these are things that certain friends, family or coworkers, over the years, did *not* know. Clip, save and pass along to…well, you know who they are.

* You can double-click a word to highlight it in any document, e-mail or Web page.
