Amazing New Technology - D-roll Laptop Design

D-roll Laptop design is a next generation concept which is way unique from usual laptops in both shape and function. The long tube shape of this laptop, which was motivated from the storage tubes that artists are using for storing large drawings, eliminates perception of the traditional book looking laptops.

This multifunctional laptop has two working modes. When it is operating in full function mode, the laptop is unfolded completely and all peripherals are turned on. The main display is turned off and a smaller screen, attached with main body is turned on allowing the users to check and send mails when D-roll is under email mode. VC is a helpful add-on for capturing pictures or videos and Locking System can provide certain security to the laptop.

Microsoft's new technology - PhotoDNA

STATE and federal police will begin using sophisticated image-matching software to tag and track child pornographic images in an attempt to reduce their sharing across the internet.

The technology, developed by computer giant Microsoft's research group along with scientists from Dartmouth College, creates a unique signature on a digital image that could be compared with the signature of other images to determine if they were copies.

Microsoft's new technology - PhotoDNA
The manager of cyber crime operations at the Australian Federal Police, Glen McEwen, said when police came across child abuse material their first priority was to establish whether the images were new, and the child was still at risk, or whether they were versions of known images.
That process was currently carried out manually by police officers, he said.

Commander McEwen said,”access to the new technology, called PhotoDNA, will mean police could identify victims and apprehend abusers faster, and make it easier for enforcement agencies to share information”.

The technology would also limit officer’s exposure to disturbing material, he said.

New iPad: A polishing of the old

Because if you ask for the iPad 3, the Apple representatives will look at you funny. Last year's model was called the iPad 2, but this third-generation model is just called the iPad. (Why not continue the numbering pattern? "That would have been too predictable," says Phil Schiller, Apple's senior vice president for marketing.)

New iPad

Really, the new iPad should have been called the iPad 2S. In the past, Apple added the letter S to iPhone models that weren't exactly new but had been tastefully enhanced (iPhone 3GS, iPhone 4S). That's exactly what's going on with the new iPad. Its technical improvements keep it at the forefront of desirability - just ahead of the snapping jaws of its Android competition - but don't take it in any new directions.

The biggest new feature is what Apple calls the Retina display: like the one on the iPhone 4S, it's a very, very sharp screen. It's four times as sharp as the iPad 2 - in fact, it's the sharpest ever on a mobile device. This screen has 3.1 million pixels, which is 1 million pixels more than on a high-definition TV set. (At least Apple says that that's how many pixels it has; I quit counting after three days.)

In principle, that avalanche of pixels (and their increased color saturation) means that photos, videos, maps and text should look jaw-droppingly good - and, in apps that have been rewritten for the new screen, they do. Apple's own apps, like Photos, Maps and iBooks, are just incredibly sharp and clear.

So are Apple's inexpensive, newly enhanced iPad apps - iMovie, GarageBand, the Numbers spreadsheet and the Pages word processor. And as touch-screen apps go, the new iPhoto for iOS is a masterpiece.

But apps that haven't been rewritten don't benefit as much. In most apps, text is automatically sharpened, but not in all of them. After enjoying the freakishly sharp text in Mail and Safari, you'll be disappointed in the relatively crude type in, for example, the non-updated Amazon Kindle app. (Amazon says that a Retina-ready update is in the works.)

Similarly, high-definition videos look dazzling. This is the world's first tablet that can actually show you hi-def movies in full 1080p high definition. But Netflix's streaming movies don't come to the iPad in high definition (yet, says Netflix), so they don't look any better.

There's another price you'll pay for all this clarity, too: in storage. Tests performed by revealed that the graphics in Retina-ready apps consume two to three times as much of the iPad's nonexpandable storage than pre-Retina apps. To update their apps for the new display, software companies must redo their graphics at much higher resolution, which means much larger files.

(Worse, each app is usually written in single, universal version for all iPad models. So those apps will eat up the same extra space, pointlessly, on older iPads, too - and even on iPhones, since many apps are written to run on both the tablet and the phone. In other words, iPhone owners, too, will wind up losing storage space because of this graphic-bloat ripple-down effect.)

The resolution revolution isn't the only change in the iPad That Shall Not Be Numbered. Another big change is 4G LTE.

That is, the cellular iPad models can now hop onto the very fast 4G wireless networks for data that Verizon and AT&T have built in big American cities.

(Apple has not changed the prices and configurations for the new iPad. The base model still costs $500, has only Wi-Fi and holds 16 gigabytes. The top-of-the-line model still costs $830, has 64 gigabytes of storage and can also get online via a cell network. You have to choose either the AT&T or the Verizon model, in that case, and pay a monthly fee - $15 to $50 a month, no contract required. These iPads can also get online overseas, although only at 3G speeds; LTE uses different frequencies in other countries.)

Being on LTE flavor of 4G is really, really nice. Apps download quickly. Web pages appear fast. You don't have to wait for videos to load before they start playing. The Verizon iPads offer tethering - a feature that converts that cellular Internet connection into a Wi-Fi hot spot - so nearby laptops can now enjoy the same high Internet speeds. (AT&T says it's working to get tethering.)

My Verizon test unit got download speeds ranging from 6 to 29 megabits a second in San Francisco, Boston and New York - in many cases, faster than home cable-modem service. According to tests by PC Magazine and others, AT&T's 4G network is smaller, but often faster. No doubt about it: life begins at 4G.

Now, 4G is a notorious battery hog. It scarfs down electricity like a football team at a hot dog eating contest.

Apple, however, was determined to keep the iPad's battery life unchanged from the last model: nine to 10 hours on a charge. In my all-day nonstop-usage test, it did manage nine hours.

To pull that off, Apple adopted a three-prong strategy. First, it developed or adopted components that use less power (Bluetooth 4.0, for example). Second, it came up with various software and circuitry tricks.

Third, it incorporated a fatter, heavier battery. The new iPad is one millimeter thicker, and 1.8 ounces heavier, than the iPad 2. It's a very slight difference, but fingers used to handling the old iPad will feel it, and that's too bad.

Interestingly, you can turn off the LTE antenna in the Settings app. Without that power hog, you'll probably get even better battery life.

So what else is new? A 5-megapixel back camera that takes far better photos than the iPad 2 did. (Which isn't saying much.) You can capture 1080p hi-def videos now, and a stabilization feature lends a hand when yours is shaky or moving.

A tiny microphone now appears on the on-screen keyboard. Tapping it lets you speak to type, exactly as on the iPhone 4S.

For most people, that's a huge blessing; typing on glass has never been a joyous activity. The recognition is fast and accurate, at least when you have a strong Internet connection (the transcription is actually performed by faraway servers).

Weirdly, though, speech-to-text is the only piece of Siri, Apple's smart voice-control software, that the new iPad inherits from the iPhone 4S. You don't get the rest of Siri's features: the ability to set alarms, send text messages, look up calendar appointments and snag facts from the Web just by asking out loud. That the full Siri isn't available smacks more of a marketing department holdback than technical limitations.

The world has changed since the iPad 2 came out. Stripped-down, smaller and far less magical rivals like the Kindle Fire and the Nook Tablet cost only $200. (That, probably, is why Apple still sells the iPad 2 at $100 less than the new models.)

Dozens of would-be iPads have come - and, in many cases, gone. (Shall we have a moment of silence for the Hewlett-Packard TouchPad and the flailing BlackBerry PlayBook? Nah.)

But the surviving rivals still sell in minuscule numbers compared with the iPad, and that's not likely to change now.

Apple’s new iPad sale begins this Friday

Set your alarm clock, or get ready to pitch a tent outside your nearby Apple retail, the new iPad goes on sale beginning at 8 a.m. this Friday. The lines should be fierce, especially with pre-orders selling out shortly after last week’s launch event. And it’s a first-come, first-served basis. On the plus side, five other big-box retailers will peddle the popular tablet on Friday, too.

Apple’s new iPad sale begins this Friday
If you’re not hung up on getting your goods straight from the source, you can pick up the new iPad from Best Buy, Radio Shack, Target, Sam’s Club and Walmart. This is especially good news for anyone lacking an Apple store in their town, but there are some serious advantages to picking up your tablet from its maker. For one, Apple locations will most likely have a greater quantity of devices to sell. But we think the biggest draw is the free setup and support that the company offers for in-store purchases.

The new iPad will also be available in the U.K., Australia, Canada, France, Germany, Hong Kong, Japan, Singapore, Switzerland, Puerto Rico and the U.S. Virgin Islands on March 16. Beginning March 23, it will go on sale in Austria, Belgium, Bulgaria, Czech Republic, Denmark, Finland, Greece, Hungary, Iceland, Ireland, Italy, Liechtenstein, Luxembourg, Macau, Mexico, the Netherlands, New Zealand, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain and Sweden.
