Now, watch 3D TV without glasses

Posted: September 16, 2011 in Tech Info

Fraunhofer research scientists are optimising a technology that makes it possible to watch TV in 3D without technical aids such as 3D glasses. “A breakthrough in 3D television would only come when you don’t need glasses. Wearing them is just too uncomfortable and tiresome,” says Frederik Zilly, of the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute (HHI), Berlin. Research scientists at HHI are now working with 12 partners in the MUSCADE project to develop such a technology.

For this, autostereoscopic displays are needed. These are coated with special optical foils. They create two different images each—for both eyes—the basic principle for three-dimensional vision. To allow different viewing positions—for instance, when the viewer moves his head—these displays use five to ten different views of an image. As conventional stereo productions only have two views, the captured images have to be converted before transmission. In order to reliably determine depth information, more than the usual two cameras are used. The MUSCADE project partners use four cameras, but this makes the already complex stereo production extremely intricate and expensive.

It wasn’t that long ago that desktop and notebook computers came with just enough hard drive spaceto get you by. These days, however, most new systems come with ample storage space for the majority of the population, but power users still might find their drives filling up quite quickly with music, movies, and games. But fear not, media lovers, IBM can build you a data drive with 120 petabytes of storage to hold every music, movie, and picture you’ve ever seen — and all you need is a deep bank account and a team of computer scientists to build it.

The ambitious project is currently underway at IBM, where researchers are working with 200,000 individual hard drives to create the single largest digital storage space known to man. When complete, the drive will have 120 million gigabytes of capacity, which is enough room to store roughly 24 million feature length HD movies. The epic drive also allows old or broken components to be swapped out without losing any data or requiring costly downtime.

IBM is crafting the custom storage center for an unnamed client that needs to perform massive simulations. The company hasn’t revealed the cost of the project, but with IBM engineers taking on the task, you can bet it’s not being built for a home office.

AMD Radeon HD 6990 Review

Posted: August 23, 2011 in Tech Info

When we took a look at the reference version of AMD’s Radeon HD 6990, we found a board that was impressive on a number of fronts, though not all the impressions were positive. The HD 6990 builds in two full Radeon HD 6970 GPUs onto a single board, each with its own 2GB of frame buffer. In our initial testing, performance looked to be very fast, but the reference board was also pretty noisy under load.

So we waited to get a shipping board from one of AMD’s many board partners in order to formally review a real product. And we waited. And waited some more. (Bear in mind that availability of Nvidia’s GTX 590 isn’t much better.)

At last, XFX shipped us an actual retail Radeon HD 6990, so we’re finally able to render a verdict on AMD’s killer card. Before we dive into benchmarks and observations, it’s worth recapping the specs and features of the card, and its GPUs.

The Radeon HD 6990 has five total display connectors, though it does cut back on the variety compared to the HD 6970, with four Mini DisplayPort connectors and a single dual-link DVI connector. XFX includes a pair of Mini DP–to–single-link DVI adapters (one passive, one active) plus one Mini DP–to-HDMI adapter in the box. With two GPUs and 4GB of GDDR5, this is a big card—over 12 inches long. It also requires two 8-pin PCIe power connectors.

It’s also worth looking at core clock differentials. Nvidia reduces the core clock speed of its dual-GPU GTX 590 card by more than 20 percent, from 772MHz to 607MHz. By contrast, AMD lowers the core clock speed of the HD 6990’s GPUs by only about 6 percent. It could be that AMD’s GPUs are more power efficient, or simply that AMD is being more aggressive about its overall design. Given the HD 6990’s noise level under load, we suspect a little of both.

As with the reference card, the XFX card has that overclocking mini-DIP switch that allows you to push the clock speed up to 880MHz—the same core clock as a single-GPU HD 6970 card. However, XFX puts a giant yellow caution sticker over this switch. Given that rather dire warning, we tested the card at its default 830MHz clock speed.

Now that we understand a bit more about the key features, let’s look at performance.

AMD’s HD 6990 wins seven of our benchmarks, ties in one, and loses to Nvidia’s GTX 590 in the remaining three. The 6990’s maximum power draw is marginally lower. All of the games we tested support CrossFireX; if you’re running an older game that doesn’t support AMD’s dual-GPU technology, you’ll only see the performance of a single HD 6970. However, AMD’s done a ton of work with its drivers, and all the current-generation games we’ve tested get a solid performance boost.

On the other hand, the XFX HD 6990 is considerably louder at full throttle than the GTX 590. Clearly, AMD has some work to do with its cooling solution to reduce noise levels. Or maybe AMD is just pushing those 40nm-based 6970 chips a little too hard, even at the lower clock speeds. As you might suspect given the fan noise, the HD 6990 gets quite hot at full load, so you’ll definitely want a case with robust airflow.

The bottom line: XFX is shipping the fastest graphics card you can buy—that is, if you can find one. Availability is still very tight, and if you order one, expect it to be backordered for several weeks. It’s also quite hot and quite loud, so be aware of that before buying. And all that performance comes at a price—the HD 6990 is also the most expensive card you can get, with prices ranging from $700-$800 depending upon the seller.

Still, if you’re really looking for raw speed in a single graphics card—noise, heat, and price be damned—the HD 6990 is the frontrunner.

Now closing on its second month, the Google+ social networking platform has seen rapid growth — and lots of attention — in its short lifetime. But new research indicates that the lion’s share of Google+ users do not actually pitch in on the site very often, if at all.

Here are some interesting tidbits from data compiled by Bime Analytics, which polled a voluntary sample of more than 10 million Google+ users

  • Students are taking over. As of mid-August, the dominant occupation for Google+ users was “student.” That’s a big shift from the month prior, when the dominant occupation was “engineer.”
  • It’s still a man’s world. The percentage of female users was 30 percent, a slight increase from the month prior when women made up 28 percent of Google+’s user base.

C++ is an old language, but still very popular and relevant, especially while creating performance-intensive applications. It hasn’t remained unchanged since its inception, the language has been standardized and updated, but the most significant update to come yet has been in development under the name C++0x for quite a while.

C++0x was intended to be finalized before 2010, with the x standing for the year in 2000 in which it is released, however, this is 2011 and the final standard that emerges from C++0x will ths rightfully be called C++11.

ISO has just declared “unanimous approval” for the new standard, and it is likely to be published soon as “ISO/IEC 14882:2011(E) Programming Languages — C++, Third Edition”.

The new standard aims to evolve the language while making things such as multithreading simpler. It even has a provision for garbage collection; but that is dependent on the specific implementation of the standard, and it not enforced by the standard.

For those who are familiar with C++, a list of changes and improvements compared to the previous version can be found on its Wikipedia page. For those looking for a more practical look at C++0x, the popular free open source GNU Compiler Collection has been implementing C++0x features while the standard was being developed. You can see what all it supports here.

1) Google’s reputation on social network
We are talking about Google’s reputation o0ver social network,as we could easily remember the history with Google’s previous attempts for social product.Google has tried so many social products but could you remember one which are still hot listed this days like Facebook or twitter.We can compare with many more social network but I think comparing with Facebook and twitter is enough here.
Some of us will try to remembering us about YouTube,but my dear friend we can say YouTube was not a product of Google.When Google brought this social network which mainly deliver videos products was enough hot item for social market.You can say Google has just trying to maintain YouTube’s brand reputation.
2) Google reputation for privacy
Once again we are talking about Google reputation over privacy of social network they launched.When Google launch Google Buzz,it was hot cake for social user but due to Google’s unique privacy policy people return their hands from it.I can remember what the craze was when Google launch Google Buzz but with the time it all lost.This mainly because of Google’s own privacy policy.
In similar fashion Google plus will deliver dead letter private profile on 31st July.I don’t know why but people wants private profile too.Though its most debatable issue.
3) twitter alternatives
Twitter are growing rapidly,we can see twitter has some new changes this year in their policy and tactics.So this could create huge threat to Google plus.They are integrated into hugely popular iOS,so people can’t leave them or save some time to have more time with Google Plus.I know they will simultaneously use Facebook and Google plus but it just because nothing to loose by using any other product.

4) Big threat from Facebook
This days Facebook are much more good alternative to anything else.They also has private profile options,so the user who want this will not move to Google plus.

5) Google’s own success as search engine

People won’t think Google except a search engine.We know Google means anything to search on Google.This past success always create obstacles for user,when they heard about any product from Google.Though this is very much prediction over people’s mind but it might create a threat to Google plus.
On the other hand Google has some strong competitor for this section.Bing is now rapidly growing into its search field.So Google has to think about this too.

6) No re-tweets and Like button
Like twitter and Facebook Google plus doesn’t has any re-tweet and Like button.Now a days this two buttons are hot thing for social users.Through re-tweet button someone can easily re-share any content and again through like button you can leave your faith to any content.According to Google new algorithm updates,Google has decided own to give importance to re-tweeting and liking content.
Though through Google plus you can share any content to global if its already shared by a circle.

7) Total complex theorem through-out Google plus
One can easily say Google plus nothing but a complex algorithm like Google has with its previous products.Implementing Google plus is quite hard in one word.One has to complete various things before result comes in.

Mona Sandhu, a lecturer turned costume jewellery designer, set up a jewellery store in her home city of Karnal, Haryana, in 2006. The five-year-old store was doing well, selling about 70 pieces a week, but the limited pool of customers was stifling for the ambitious businesswoman.

On a whim, Sandhu set up a profile on Facebook at the end of last year with photographs of some of her products. To her surprise, she bagged an order the same day from a customer in California. Ten months on, Sandhu, whose social media page has been liked by 17000 visitors, is busy planning exhibitions in the US and UK.

As business on social media gains rapid acceptance, small-town entrepreneurs are securing customers from across the world. Sandhu gets over 100 orders a week mostly from customers in the US, Canada and the UK. On an average, individual customers order 5-10 pieces at a time, while a wholesale order starts at 40. “I have international recognition which has helped increase sales by 20 times since the launch of the page,” says Sandhu for whom the Facebook page is the sole link with her customers.

For scores of entrepreneurs like Sandhu living in non-metros and towns with tight marketing budgets and no experience of running a commercial enterprise, Facebook has emerged as a significant marketing and sales tool. In fact, many of them are using their Facebook page as a substitute for a proprietary website. It costs nothing to set up a page, profile or group and it provides space for displaying photographs to boot.

LG Optimus 3D Review

Posted: August 15, 2011 in Tech Info

The world’s first, and the most anticipated, glass-less 3D phone hits Indian stores by the end of this month.

Some manufacturers-most notably Nintendo with its 3DS gaming console have done away with glasses by using ‘auto stereoscopic screens’ which give you the impression of action happening on and in front of the display, although this works only from a specific viewing angle. But even this has met with limited success. India’s first 3D phone-the Spice M-67 3D-for instance, generated more interest than actual sales.

So, it was with a fair amount of curiosity that I approached the LG Optimus 3D, the world’s first glass-less 3D smartphone that was announced with much fanfare at CES this year and which is expected to launch in the country by the end of this month.

Smart phone, 3D entertainer
Straight off, and no two ways about it: The Optimus 3D is bulky. It is 12mm thick and tips the scales at 160-odd gms; a far-cry from the sub-10 mm smartphones of today. However, what marks it out as special is its display. It boasts a 4.3-inch , 800×480 auto stereoscopic screen – the biggest and the highest-resolution display I have seen in a handheld 3D gadget.

As far as specs are concerned, the device packs in a 1GHz dual core processor, 512MB of dual channel RAM, HDMI connectivity, and two 5 megapixel cameras. I was, however, surprised to see it running Froyo (Android 2.2) rather than Gingerbread (Android 2.3) – shades of the Optimus 2X, in which the latest hardware rubbed shoulders with a relatively dated OS. Surely, such a powerful device would have been better served by Gingerbread.

In terms of appearance, the Optimus 3D seems like a regular (if chunky) Android phone. The touchscreen dominates the front with four touch keys beneath it, but its main selling point is its 3D prowess. Before you ask, no, not everything on the phone is in 3D – you can view images and videos (there is even a link to view 3D videos uploaded on YouTube) and play games in 3D, and also add a third dimension to routine 2D images and videos by hitting the 3D button (which is on the side of the phone). You can even create 3D content – the Optimus 3D’s dual cameras let you take images and videos, which you can view on its display or on a 3D TV, if you have one.

The camera threw up ordinary results in videos, where there was a fair deal of blurring, but was awesome for still images, especially for landscapes – you could almost see the clouds floating in front of the display. Interestingly, the camera works better in 3D mode than in 2D.

But where the device’s 3D really shone was in gaming. LG has done well by including four very high-profile titles on the handset – NOVA, Asphalt 6, Let’s Golf 2 and Gulliver’s Travels. My own favourite was NOVA, a first person shooter where I could actually feel the gun in front of me. The large display, very responsive touchscreen and the uber-fast processor made gaming buttery smooth. The 3D experience itself was not as good as with glasses in a cinema hall or in front of a 3D TV – you do not get the kind of depth, colour and “real 3D” feel as with glasses – but truth be told, I found this more convenient, simply because I could use it anywhere – in public transport, outdoors; and without any glasses.

Pros
Ability to view as well as create 3D content, zippy performance as can be expected from an Android smartphone, excellent hardware

Cons
Older Android OS, bulky and not the prettiest phone around, definitely on the expensive side, 3D usage drains battery heavily

“Make a billion, lose a billion.”

This was the wry comment of a boyhood friend, a Wall Street hedge fund manager, shortly after the 2008 financial collapse. I thought he was joking.

Yet after learning that the top 25 hedge fund managers in the U.S. last year enjoyed an average take home pay of $880 million (U.S.), I realized it was no joke. (And their 15 per cent tax rate loophole continues.)

As markets bounce like superballs in light of the United States’ loss of its triple-A credit rating in the eyes of Standard and Poor’s, and speculation grows that France, the second-largest economy in the Euro-zone, may suffer a similar credit rating downgrade as their banks deal with the financial firestorms of Greece, Ireland, Portugal, Italy and Spain, fears of a second global financial meltdown have whipsawed the financial world.

To quote former Yankees catcher Yogi Berra, it seems like “déjà vu all over again” in the global economic scene.
