SmartRings

A high-tech ring that promises to replicate many of the features found in the latest crop of smartwatches, but without strapping a brick to your wrist, is now one step closer to reality.

Here’s how to set yourself up for success in 2014

As the old saying goes: your goals don’t work unless you do. You will likely face bumps in the road and moments when you feel as though you’re not making progress. When this happens, remind yourself of all that you have done, refocus, and keep going.

Science

“This is completely new and very much simpler than anything that has been done before,” said Andrew Hodges , a mathematical physicist at Oxford University who has been following the work.

Flat. Like a streak across space. Thin. Stretched out. How come whenever we see galaxies, they always look like this

NASA has the answer. And it has something to do with how a ball of dough becomes pizza.

The Masks We Wear

The smiles and laughter we display are clever devices hiding our pains and sorrows we carry within us. While tears and heart break are displayed for all to see revealing the thin cracks of the mask that we wear, allowing a small portion of how we truly ache inside be seen from observers quietly watching for you to reveal yourself. - Se more..

iPhone 6 To Feature Sapphire Glass Screen and Solar Charger: Rumours

Apple is expected to unveil its next iPhone model later this year and the rumors about what the device will feature are flying. A few days ago, we mentioned that a test run of 100 units of the iPhone 6 with the sapphire glass screen had reportedly been made by Foxconn. In February of 2013, a patent surfaced that suggested an iPhone with a solar charger was on the way.

Today a new rumor has surfaced that combines the sapphire glass screen and that solar charging patent into something new. According to this rumor, the sapphire glass screen of the iPhone 6 will feature solar charging capability. It's unclear if the rumor is suggesting the screen will have an integrated solar panel or if they will be separate items.

Integrating a solar panel along with that sapphire screen in a smartphone would be something completely new in the market. The source of the rumor tips that the goal is to help keep the smartphone topped up and running as long as possible. Battery life is becoming a challenge as people use their devices more and power demands rise with more processing power and larger screens.

One of Apple's patents for the touchscreen solar panel tech hinted that the touch screen had a power management system that was able to take power from solar panels. This is pure rumor at this time, so take it with a grain of salt. We do know that Apple patented this sort of tech, so a solar charging iPhone 6 is certainly possible.

South Korea's 5G: To Let You Download A Full Movie In One Second

South Korea's science ministry wants people on the fastest bullet trains to be able to surf the Internet.

The country's science ministry is investing $1.5 billion in building 5G wireless service for the country by 2020, AFP reports.

Some of the things the ministry wants 5G to do include downloading an 800-megabyte movie in one second, and providing Internet access to people onboard 500-kilometer-per-hour (310 miles) bullet trains. Yes, I would like to live there, too.

2020 seems to be the deadline many groups are taking for developing the next generation of data networks. Samsung, the European Union, and Chinese device manufacturer Huawei have all said they'll work on commercializing 5G by then. There's plenty of work to do. Beyond improving speed to hundreds of times faster than today's 4G, 5G should have fewer dead zones and use less power than 4G, VentureBeat reported last year.

Everything You Need To Know About Jelly: An iOs & Android App.

Jelly, the much-hyped, question-and-answer-based social network by Twitter co-founder Biz Stone, launched last week on iOS and Android.

Although it's just beginning to build up a user base, with a famous founder and impressive list of investors (which includes Bono and Al Gore, along with Stone's fellow Twitter co-founders Jack Dorsey and Evan Williams) the service likely won't be going anywhere anytime soon.

If you're still not sure how Jelly works or if the service is for you, here's what you need to know.

What Is Jelly?

Jelly's goal is to help users find answers to their questions in real time by crowdsourcing opinions from their social networks — sort of a cross between Quora and Snapchat. Users snap a photo, ask a question, and get answers from connections in their social networks.

Stone says he developed the idea because there are some questions that can't be answered with a simple Google search. "Jelly changes how we find answers because it uses pictures and people in our social networks," Stone explains in Jelly's blog. "It turns out that getting answers from people is very different from retrieving information with algorithms."

Getting Started

Begin by connecting to at least one social network (right now, Facebook and Twitter are the only ones available). Part of what makes Jelly stand out is it also links you to friends of friends, so you can still connect with other users, even if none of your Facebook friends or people you follow on Twitter are using the service.

Each question begins with a photo. You can either snap a new photo, pull one from your device's camera roll or use a photo from Google Images. You can also draw directly on your photo, similar to Snapchat. After choosing your image, you type out your question (text is limited to 240 characters but can include links).

Answering Questions

You can see when people answer your questions under the activity header, which holds all of your notifications. Answers appear in cards underneath the text of your question. Swipe between the cards to view all of your responses. If you particularly like an answer, you can send the user a thank you card or share their answer via email, text message, Facebook or Twitter.

At the bottom of the screen is a tray showing how many other users need help answering questions. Questions appear as cards with the text overlaid on the photo. Answering questions works much the same way as asking —answer with text, a link, or by drawing on the photo (or any combination of the three). If you don't want to answer, swipe down to move to the next question card.

Forwarding and Following

While asking and answering questions is at the heart of the app, there are other ways of interacting with questions. Star questions you're interested in following in order to receive notifications as the questions are answered by other users.

And, taking the crowdsourced approach a step further, questions can be forwarded to friends who don't use Jelly, via email or text message. Forwarding questions sends a link to the question, which can be viewed from a browser by those who don't have the app installed. Non-Jelly users can then answer questions the same way as users of the app, with text, links or by drawing on the photo.

Where's It Going?

While the app is still in its infancy, it does seem Jelly has already built up a sizable user base. According to statistics from RJ Metrics, Jelly had 8,275 active users on its first day alone. Though impressive, Jelly's biggest hurdle right now, according to RJ Metrics, is maintaining engagement. While Jelly users asked almost 100,000 questions in the app's first week, only about a quarter of those questions were actually answered.

Adding more features will also be key to maintaing engagement. At this point, the app itself is still relatively bare-bones, with little organization. There's no way to search or sort through questions for topics you're interested in, for example, and the only way to browse is by manually swiping through each card. There's also no way to view which, if any, of your friends are using the service. The app also lacks a back button, which can make navigating between screens tricky.

Play-i's Bo: A Charming and Loveable Tiny Robot

When we last met Play-i’s charming robots Bo and Yana they were busy pounding out tunes on a little colorful Xylophone and raising $1.4 million in crowdfunding cash. Now, however, they’re very nearly ready to ship and are doing some really impressive things that will help kids learn programming while having fun.

You can think of Play-i’s toys as sort of like the simple programming language, Logo, in physical form. You can program the robots using your iOS device and there are a series of introductory games that teach you the rudiments of programming including functions, subroutines, and loops. For example, the app asks you to play certain notes on the xylophone using Bo’s robotic arm – say five blue notes and five pink ones. To do this you must program the robot to hammer down five times, move over a few spaces, and hammer down five more times.

You can also add accessories to the robots and create, say, a platform for your LEGO creations or a mobile spy platform. While I’m always very skeptical of tech toys – they end up in the junk box far too soon and are often far too expensive – I’m impressed with how far the team has come in just a few short weeks. It looks like the product will soon be ready to ship and we will all have weird, blue robots running around our house busily hammering out jaunty tunes on our pets.

Arcam's miniBlink: A tiny gadget to help you stream your Music to a high-end Audio System.

The tiny miniBlink Bluetooth DAC is a greatway to link your music player to a conventional hi-fi.

Those of us who grew up in the age of analog hi-fi are perhaps still a little uncomfortable with the concept of having all our music held in digital format. It may be convenient to have all your music on one small device, but nothing beats the pleasure and ceremony of putting a vinyl album on the turntable or selecting a CD to play on a decent audio system. Then it’s a case of settling back in a comfortable chair with a drink and unwinding to some late-night jazz or whatever takes your fancy.

That scenario is perhaps a little quaint in the digital age now that most of us also own a large collection of music on our smart phones, MP3 players or laptops. Digital music collections are so convenient and there isn’t the hassles of rooting around for a CD you haven’t played in years. However, the thought of plugging a cheap MP3 player into a decent hi-fi system goes against every fiber in the average audio buff’s body.

Well, now there’s the Arcam miniBlink, a lightweight and affordable (£89/$149) new device for wirelessly streaming music from a smartphone or MP3 player to any audio system. The miniBlink uses the latest Bluetooth technology from CSR & Arcam, offering lower noise and lower distortion levels than previous versions of Bluetooth streaming DACs. This improved Bluetooth performance has enabled Arcam engineers to squeeze a level of sonic purity that it claims can rival the audio quality you’d expect from a conventional CD.

The miniBlink weighs just 40 grams and has a cute little pebble shape and can stream music from Android devices, iPhone, iPod Touch, iPad, PCs, Macs or tablets. As long as the streaming device has a Bluetooth interface it will work with the miniBlink. Power for the DAC is drawn from a micro USB socket and the audio output is delivered to your stereo through a standard 3.5mm stereo jack.

Intel's 64-bit Bay Trail CPU coming to Android Gadgets

Sure, 64-bit support is all the rage nowadays in the mobile space, what with Apple setting off a trend with the introduction of the iPhone 5s.

Now, according to Intel's CEO, tablets running Google's operating system are next and will soon be available with 64-bit compatibility. During an earnings call yesterday, Intel chief Brian Krzanich said that Android tablets using the company's new Atom-based Bay Trail processor are set to hit the market as early as this spring, bringing along a technology which so far has been limited to Windows 8.1 devices.

It's also worth noting that while 64-bit slates may be arriving soon, the number of Android applications optimized to take advantage of the feature will be very low at first. Still, chances are developers will quickly take care of this as more and more 64-bit-ready phones and tablets start to become available.

Google Shows Off Smart Contact Lens, A Small Gadget Meant for The Diabetics.

Google is working on a new project, this time its something that's going to be very close to your eyes. Yeah Google is developing smart contact lens, and amazingly it can be you personal health checker.

Through miniaturized electronics, it can apparently measure the levels of glucose in your tears, offering diabetics an easier way to monitor their condition without the needles and the blood -- something we've reported on a several before. A tiny (really tiny) wireless chip and glucose sensor are wedged between two layers of "biocompatible" contact lens material, and Google is saying that it's already working on embedding tiny LED lights for notifications, too. There's been no shortage of developmental contact lens tech over the last few years, but the clout of Google means this could well be the most realistic mainstream offering, in addition to its very practical use cases. Google is currently angling for partners with more expertise in the medical market to help make it happen and is "in discussions with the FDA" to ensure the tech ticks all the right healthcare boxes before it progresses further.

Recode's got a deep dive on the make-up of the smart contact: we've added their science textbook-grade diagram right after the break.

Meet HaloBand: A cool gadget to control your smartphone with just a Tap on your Wrist.

The rise of mobile has given me so much: 24/7 connections with friends around the world, information exactly when I need it, the ability to track my fitness and health goals. Unfortunately, it’s also given me a complex about my giant sausage fingers and their constant inability to navigate the tiny keys on my smartphone’s slippery touchscreen. Sometimes I think I should have just bought a BlackBerry.

When I read about Haloband on their Kickstarter page , I felt like the Shanghai- based startup was speaking directly to me: “Everyone has trouble in locking and unlocking smartphones. The frequency usually hurts phones’ screen and keys, as well as our hearts. So we decided it’s time to do something.”

Haloband is a silicone wristband that is embedded with NFC chip and lets you operate your choice of functions by tapping your Android smartphone on your wrist. It’s also linked to a cloud account, which lets you save your ID as well as information you can send to other mobile devices. After setting up your wristband with the Haloband app, you can use it to unlock your phone, take photos or send emergency alerts, among other options. To get an idea of what Haloband can do, watch their hilarious Kickstarter video embedded above (“I’m from the future. If you scan my wrist, you can get my business card information. This is my information, from my wrist, on your phone. Because I’m from the future.”)

The project has already raised almost double its $10,000 goal on Kickstarter and its early bird specials are closed, but you can still select from several options, starting from just $25 for a black or white Haloband. Funding closes on Jan. 16 and the bands are scheduled to ship in February.

Haloband was developed by a Shanghai- based team that includes a former Intel engineer and focuses on NFC technology. They plan to release an open API so other developers can create their own Haloband apps and help smartphone users wrist easy (rimshot).

Samsung Announced the Galaxy Camera 2

Samsung on Thursday announced the Galaxy Camera 2, the sequel to last year’s Galaxy Camera. It’s actually the same exact camera as the original, with some modest improvements to the software, as well as a bigger battery and NFC support.
The Galaxy Camera 2 features a 16-megapixel image sensor and 21x optical zoom lens. There are some physical changes, like a hinged flash, as well as a similar faux-like build to the Galaxy Note 3 .
Samsung has increased the number of Smart shooting modes to 28, and you can separate exposure and focus, controlling them via the camera’s rear touch display. The Galaxy Camera 2 runs Android 4.3 (Jelly Bean), which brings a host of improvements over Android 4.1 found in the original. But like its predecessor, since the Galaxy Camera 2 runs Android, you can download apps from Google Play such as Instagram, and upload or share images directly from your camera.
The camera’s display measures the same 4.8- inches as before, with 720p resolution. But the RAM has been increased to 2GB, and the processor is bumped up to a 1.6GHz quad- core chip. The battery is bigger now as well, at 2,000mAh, so you can record longer videos. Finally, Samsung has added NFC, which will let you do things like the tap the camera to share pictures with your phone.
Pricing and availability have not yet been announced. And though the camera works over Wi-Fi, there’s no word whether carrier- specific versions will be introduced. The camera will be shown at CES next week, where I suspect we’ll learn at least some of those details. For reference, the first Galaxy Camera cost $449.99. Given the relatively minor improvements here, I think Samsung would be wise to choose a slightly lower price if it really wants the Galaxy Camera to take off.

Surface Pro 2: Shipping with a faster Core i5

Here's a toast for Surface lovers. Microsoft has confirmed that newer Surface Pro 2 tablets are shipping with a faster 1.9GHz Core i5 inside instead of the 1.6GHz chip that came with the earliest models.

Sometimes, it pays to avoid the bleeding edge of technology.  The company isn't saying just why it rolled out the stealthy upgrade, although it notes that "routinely" tweaks designs based on part availability and customer value.

The move may frustrate early adopters whose two- month-old Windows slates are already behind the times, but it's good news for latecomers who'll get more for their money.

Be Prepared for a brand new Programming language: M# by Microsoft

Microsoft is apparently creating a brand new programming language to build a non- Windows operating system.

The new language came to light on Friday when Microsoft researcher Jim Duffy blogged about it . A ZDNet report says the language is codenamed M# (“M Sharp”), though Duffy doesn’t refer to that name in his post.

Duffy describes the language as a set of “systems programming” extensions to C# that offers a better balance between “performance” and “safety & productivity” than other popular languages. His team has been working on it for four years, he said, and his “goal is to eventually open source this thing” — potentially in 2014.

In a Reddit thread discussing Duffy’s post, a self-identified former Microsoft employee said the language “grew out of Sing# , the system language of Microsoft Research’s Singularity OS .” Microsoft Research developed the microkernal-based Singularity OS between 2003 and 2010. That project reportedly gave rise to the Midori team, which was tasked with building a fast, lightweight OS that didn’t have to run Windows apps as an experiment.

But now it seems that Midori is more than a research project: it’s been moved to Microsoft’s Unified Operating System group, according to ZDNet. Midori is unlikely to see a standalone release, but pieces of it may emerge in future Microsoft operating systems.

Meanwhile, M# is being developed alongside (and utilized for) Midori. It could be used to build all sorts of applications, but may be especially useful for cloud computing apps.

Samsung's New Chips Could Put 4GB of RAM Into Every Phone

There's an inherent trade-off when designing a phone, between pure power and respectable battery life. Fortunately, Samsung's latest memory chips are so efficient that they could make 4GB of RAM in phones an industry standard—and make 4K phones a very real thing indeed.

The company's first 1GB low-power DDR4 memory chip uses a higher bandwidth than its predecessors, running at 3.1Gbps to provide a 50 percent speed boost over existing DDR3-based chips. Not only that, but the new chips use 40 percent less power, too. Squeezing 1GB onto a single die, four of the chips layered together should provide the highest capacity mobile phone RAM currently available.

Samsung only says that the new memory will go into mass production some time in 2014, but it's intended for use in ultrabooks, tablets and high-end smartphones. Indeed, Samsung goes as far as explaining that "with the new chip, [we] will focus on the premium mobile market including large screen UHD smartphones... that offer four times the resolution of full-HD imaging." Yep, that's 4K smartphones.

The bottom line, then: your next phone (or at least the one after it) will likely rock 4GB of RAM and offer rather pointless resolution. Woo!

LG to Unveil webOS- Powered TV

South Korea’s LG Electronics Inc. will soon take the veils off a television model that will run on the “webOS” operating system, highlighting its ambition of creating a prominent operating system for so-called smart TVs.

LG bought webOS, a mobile-device operating system, from Hewlett-Packard Co. earlier this year. The operating system was originally developed by Palm Inc. to power smartphones that would compete with the likes of Apple Inc.’s iPhones. H-P acquired Palm in 2010 and used webOS to power a tablet and its smartphone models. But the system failed to gain traction with the developers who write apps for devices and the devices didn’t sell well.

Despite H-P’s struggles with the operating system, LG had said in February, when announcing the deal, that it was drawn to webOS because of its technology and because the company wanted its own operating system.

LG now plans to showcase an Internet- connected television model powered by webOS in January at the Consumer Electronics Show in Las Vegas, a person familiar with the matter told The Wall Street Journal.

He didn’t elaborate on the features of the operating system, but said it would retain the “cards” system, or a stack of pop-ups that allows users to navigate multiple applications, originally used in the webOS mobile devices launched by H-P.

The person didn’t comment on the company’s plans to market the webOS-powered TVs but said the operating system may be developed and later adopted for LG’s other consumer electronics, including smartphones.

LG, the world’s second-largest TV market after Samsung Electronics Co., has been busy churning out new premium TV models this year to spark interest in a segment that accounts for nearly 40% of its revenue. The company is also set to showcase a whopping 105-inch curved-screen television at CES, with a similar model expected from Samsung.

While the market for operating systems for mobile devices is dominated by Google Inc.’s Android, there is no such leader for smart TVs.

Samsung has long been working on a new operating system, together with Intel Corp., dubbed the Tizen that is expected to power smartphones and TVs. Tizen’s expected debut next year will likely intensify the competition between the two Korean conglomerates.

Samsung launches 110-inch U- HD TV for $150,000 in South Korea

Last year, Samsung and rival LG Electronics, the world’s top two TV makers, touted OLED as the future of TV. OLED screens are ultrathin and can display images with enhanced clarity and deeper colour saturation.
But Samsung and LG failed to make OLED TVs a mainstream that would replace the LCD television sets and still struggling to mass produce larger and affordable TVs with OLED. Meanwhile, Japanese media reported last week that Sony Corp. and Panasonic Corp. decided to end their OLED partnership.
Demand for U-HD TVs is expected to rise despite dearth of content while its price will likely come down faster than that of the OLED TVs. Much of the growth is forecast to come from China, a major market for the South Korean TV makers. Chinese TV makers have been making a push into the U-HD TV market as well.
According to NPD DisplaySearch, global sales of ultra-HD TV sets will surge from 1.3 million this year to 23 million in 2017. More than half of the shipments will be taken by Chinese companies between 2013 and 2017, according to NPD.
While Chinese TV makers have been seeking to boost sales of U-HD TVs with a lower price and a smaller size, Samsung’s strategy is to go bigger with a higher price tag. Samsung’s 110-inch U-HD TV measures 2.6 metres by 1.8 metres. It will be available in China, the Middle East and Europe. In South Korea, the TV is priced at 160 million won ($152,000) while prices in other countries vary.
Samsung said it received 10 orders for the latest premium TVs from the Middle East. Previously, the largest U-HD TV made by Samsung was 85-inch measured diagonally. The ultra-HD TVs are also known as “4K” because they contain four times more pixels than an HD TV.

SD Cards Aren’t As Secure As We Think

The hardware hacker Bunnie Huang gave a talk at the Chaos Compute Club Congress where he offered some good news and some bad news. The good news? SD cards contain powerful, handy micro controllers that are useful to hackers and hobbyists.The bad news? SD cards are woefully insecure.

In a detailed and readable post , Huang describes the exact problems with Flash memory. In order to reduce the price and increase the storage space, engineers have to fight a never-ending form of internal entropy that slowly but surely scrambles the data on every Flash drive.

Huang writes:

"Flash memory is really cheap. So cheap, in fact, that it’s too good to be true. In reality, all flash memory is riddled with defects — without exception. The illusion of a contiguous, reliable storage media is crafted through sophisticated error correction and bad block management functions. This is the result of a constant arms race between the engineers and mother nature; with every fabrication process shrink, memory becomes cheaper but more unreliable. Likewise, with every generation, the engineers come up with more sophisticated and complicated algorithms to compensate for mother nature’s propensity for entropy and randomness at the atomic scale."

To take up arms against these errors, SD cards are essentially over-engineered to ensure an acceptable level of data retention. They also contain firmware that can, for example, change the visible available space on the card without changing the actual available space. This means you could sell a 2GB card as a 4GB card – your computer wouldn’t notice a difference until it started filling up that fake space. You can, incidentally, check your cards with this tool.

Here’s the worse news: because these cards contain firmware, this firmware can be updated. Huang reports that most manufacturers leave this update feature unsecured. In other words, don’t ever assume a Flash device is empty after you wipe its contents. For example, the card could make a copy of the contents in a hidden memory area or it could run malicious software while idle.

And the good news: Huang also notes that these cards could be reprogrammed to become Arduino-esque open source microcontroller and memory systems. “An Arduino, with its 8-bit 16 MHz microcontroller, will set you back around $20. A microSD card with several gigabytes of memory and a microcontroller with several times the performance could be purchased for a fraction of the price,” he writes.

So, in short, destroy your SD cards if you have any dirty info on them and keep your eyes peeled for ultra-small, ultra-fast Arduino hacks.
