 Microsoft Announces Windows 10


 This morning at an event in San Francisco, Microsoft announced the next version of its Windows operating system: Windows 10.
The name is definitely not in line with expectations, but also comes on the heels of rumor talk that it could pick up another title. Happily, the last 943 people to cover the operating system got the name wrong. I am among them.
Described as Microsoft's "most comprehensive platform ever," Windows 10 will offer a tailored experience for all hardware across a single platform family. And developers can build universal apps that will work everywhere. Here's how Microsoft describes its ambitious goal.

The Start Menu Is Back
The cat has been out the bag for some time, but Microsoft has finally confirmed the start menu will return. The leaks were spot on and it will combine both aspects of the classic Windows 7 start menu with apps from the Metro/Modern UI. Searching within the Start Menu will now perform a web search as well.
Crucially its layout can be customised so apps can be removed or resized and the flexibility and personalisation potential of the Start Menu should win back fans disillusioned about its removal in Windows 8.


  Virtual Desktops


Another leaked feature Microsoft confirmed today was virtual desktops. Microsoft didn’t give the feature an official name at this stage, but it works much like the long used multiple desktops on Linux and Exposé on Mac OS X.
The view can be triggered with a new ‘task view’ button which both allows users to launch a new virtual desktop and jump between them. Interestingly the taskbar can be customised to look different/relevant to each desktop allowing a simple leap from work to home modes, for example.
Microsoft said all open programs in the virtual desktops will continue to run in the background, which makes for some interesting memory management challenges but also greatly increases the potential productivity of Windows as well as de-cluttering the desktop space.
One thing Microsoft did not show (at least so far), is any other consumer features in Windows 10. What the company did talk about a bit, however, is that Windows 10 for the phone will look and work almost exactly like the slightly pared down modern UI on Windows 10. One thing Microsoft clearly learned from the experience with Windows 8 is that if it wants to build a single operating system and user interface for every device, it can’t just optimize for edge cases.

4K Video Resolution-

what is a 4K video?

4K – also known as UHD  -is a picture technology that quadruples the number of pixels found in a full HD picture. These pixels are usually arranged in a 3,840 x 2,160 configuration, compared with the 1920x1080 you get in a full HD TV.
While 4K is the most commonly used name for content and screens that use 3,840 x 2,160 pixels, some brands prefer the term Ultra HD – or UHD for short. 

While confusing, there is actually some logic to the new UHD term. That's because it provides a way of distinguishing between the 3,840 x 2,160 resolution adopted by 16:9-ratio TVs and the slightly different 4096x2160 resolution first introduced in digital cinemas (and actually employed by Sony’s domestic 4K projector range).

However, 4K is used so widely to describe 3,840 x 2,160 displays and content now that the roots of the technical distinction between the 4K and UHD terms have been all but lost outside of the projection world. In other words, for most people the two terms have become interchangeable

Full Aperture 4k4096 x 311212,746,752 pixels
Academy 4k3656 x 26649,739,584 pixels
Digital Cinema 4k4096 x 17147,020,544 pixels
Digital Cinema Aperture 4k3996 x 21608,631,360 pixels
YouTube enabled 4K video support in the middle of 2010. Today, it's the highest resolution format available for consumers and it has great potential! It's quite possible that the demand for this format will increase in near future, specially by digital video data delivery services.

iPhone 6: pre-orders begin for Apple's 'beautiful' handsets




The Apple Store is back online after a brief outage this morning as the company stocked its virtual shelves with the iPhone 6 and iPhone 6 Plus.
The two new phones, with 4.7-inch and 5.5-inch screens, are now available for pre-order, with deliveries expected to begin next Friday. Prices will start at £539 in the UK, for a 16GB iPhone 6, rising to £789 for a 128GB iPhone Plus.
Demand is expected to be high for the iPhone 6, which represents the most substantial upgrade and redesign of Apple's flagship phone for several years.
Even though extensive leaks of photographs and video had removed any element of surprise from the big reveal, most early reviewers have heaped praise on both the iPhone 6 and its bigger brother, the 6 Plus.
The phones are larger but slimmer, and present a softer, rounder profile than their sharp-edged predecessors.
"The wafer-like metal design and curved lines feel, in many ways, like previous iPod Touch models and a little like the iPad," says CNET. "The metal HTC One M8 feels bulky by comparison."
Investors reacted coolly to the new phones, sending Apple shares down by 0.38 per cent by the end of the launch event, but among Apple fans – and the tech press assembled in California – there was no such moderation.
"Apple's Tim Cook told the whooping crowds at the Flint Center in Cupertino that the new iPhone 6 is 'the most beautiful phone ever made'," writes Matt Warman in the Daily Telegraph. "I'm trying hard to be objective, but I think he’s right.
  • The iPhone 6 at a glance:
  • It will come in two screen sizes, 4.7 inches for the iPhone 6 and 5.5 inches for the iPhone 6 Plus. That compares with the four-inch screen of the iPhone 5S.
  • The frame of the iPhone 6 will be 6.9mm thick, and the iPhone 6 Plus 7.1mm thick. 
  • The design is a departure from recent models, with rounded sides replacing the sharp-edged, flat-sided iPhone 5S. 
  • The iPhone 6 screen resolution will be 1,334x750 pixels, which Apple describes as Retina HD; the iPhone 6 Plus will feature a full HD resolution of 1,920x1,080 pixels
  • The screen will be protected by ion-strengthened glass (but not the much-discussed sapphire crystal)
  • The iPhone 6 has improved camera specs. Although the sensor remains at eight megapixels, a new focusing and exposure system should improve image quality. The iPhone 6 Plus also has optical image stabilisation.
  • Both models can take slow-motion video at 240 frames per second. 
  • The larger screens will allow multi-tasking, allowing the user to see an email inbox and message at the same time, for example. The app dock can also be moved to the side of the screen, instead of the bottom.
  • As expected, the handsets will come a Health app that will integrate with Nike's fitness app.
  • They will also include a built-in barometer.
  • Both iPhones will be available from 19 September in the UK,
  • British prices are yet to be confirmed, but the Daily Telegraph says the iPhone 6 will cost £539 for the 16GB model, £619 for 64GB and £699 for 128GB.
  • The iPhone 6 Plus will cost £619 for the 16GB model, £699 for 64GB and £789 for 128GB, the paper says.
iPhone 6 design
The revamped design met with near unanimous praise.
"The first thing I noticed was that it feels a lot thinner than the 5s and 5c, and its rounded edges suggest you're holding a very small iPad mini rather than a larger iPhone," writes Nate Lanxon, the editor of Wired.co.uk. "The chassis has a satisfying curvature as the rear shell folds around to the front, and meets the glass of the display in a way that feels nearly seamless."
Larger screens
Wired is also impressed by the sharpness of the "Retina HD" screens on both phones, but particularly the larger model. "The 6 Plus's pixels are so tiny they're hard to see no matter how close you get your face," he says.
As well as raising the pixel count, Apple has improved the displays in other ways too, says The Times. "The screens are brighter, have crisper colours and are covered by stronger glass," the paper says. "They have also been designed for easier navigation using one hand."
However, there was no sign of the super-tough sapphire crystal screens, which some commentators had expected to see in the new phone. The camera also remained at eight megapixels, but reviewers were impressed with the improved functionality it offered.
Improved camera
"The main improvement seems to be the Focus Pixel feature, which is Apple's take on phase-detection autofocus," reports Engadget. What that means is that if you're training the camera on something in the foreground and it moves away from you, the lens will refocus automatically.
"This was demonstrated in Apple's stage presentation," Wired's reviewer says, "and I was pleased to see it works exactly as well when I tested it."
The new operating system, iOS8, also allows for greater camera control. "Until now the only way to adjust the exposure of a photo before taking a shot was to tap on the screen to tell your device from where to take the exposure reading," says the BBC's Mark Blank-Settle. "In iOS 8 the camera lets you adjust the exposure much more precisely: tapping on the screen now brings up an icon of the sun and, by moving a slider up and down, the image will get brighter or darker."
Battery life
If technology journalists had any complaints, they focused on doubts about the battery.
"Both iPhones will be powered a new A8 processor that is 25 per cent faster than the previous iPhone and 50 per cent more power efficient for increased battery life," The Guardian reports.
But on stage, Apple had only promised that battery life would be at least equal to its current models – which are frequently criticised for their lack of power reserves.
"Take your phone out for a busy day of GPSing, mobile browsing, texting on the go and whatnot, and you can drain an iPhone to zero in just a couple of hours," writes Forbes's Mark Rogowsky. And Apple "basically told the world that experience will be the same with the iPhone 6".
He blames the company for prioritising form over function, leaving limited room for the battery by cramming all the components into a slim frame with rounded edges.

Live: Apple launches iPhone 6 and iPhone 6 Plus

9 September
7.20pm: Tim Cook returns to the stage to walk us through the next revelation of the evening, the Apple Watch.
6.55pm: Apple confirms that it will be introducing a payments system that will work in 220,000 locations around the world including, naturally, Apple Stores. The system works in partnership with American Express, Mastercard and Visa, and allows users to pay for goods by holding the iPhone 6 against a reader, as if it were a contactless payment card. Transactions are authorised using the phone's fingerprint reader. "Cashiers don't see your name, your card number or your security code," Forbes reports.
6.30pm: In a flurry of superlatives, the Apple demonstrator says the iPhone 6 will be larger, thinner and faster than its predecessor. But the promise on battery life - that it will be equal or better - dashes hopes of a big leap forward on that front.
6.15pm: The Daily Telegraph reports that "these phones are thinner than anything Apple has ever made: 6.9 mm"
6.10pm: Tim Cook, Apple's chief executive, arrives on stage a little late, but he breaks with company tradition and goes straight to the big news: Apple is launching two new phones, the iPhone 6 and iPhone 6 Plus. Cook's predecessor, Steve Jobs, always started with routine announcements and saved the biggest unveiling until last.
Does Apple slow old iPhones before a new release?

iPhone 6: what to expect

9 September
As the world's technology press descends on Cupertino, California, for the launch of the iPhone 6, the Apple rumour mill has gone into overdrive. In the year since the relatively low-key launch of the iPhone 5S and 5C, rumours have come and gone about the new specs and features likely to find their way into its successor.
While some of it seems to be based on wishful thinking, much is likely to prove well founded. Here is our round-up of the most frequently discussed iPhone 6 specs, and how likely they are to make it into production.
iPhone 6 launch date: Analysts are expecting two versions of the iPhone 6, but it is unclear whether both will make an appearance tonight. It'll be a huge surprise if Apple doesn't produce a 4.7-inch device, but some analysts also expect to see a larger, 5.5-inch handset. Others think that the bigger iPhone 6 will not appear until later in the year. It's also unclear when the new phones will go on sale, but 19 September is the date most frequently predicted.
iPayments: Recent reports suggest that Apple is working on a mobile payments system that will be unveiled alongside the iPhone 6 on 9 September. "Apple has reached an agreement with American Express to work together on its new iPhone payments system," Re/code reported, and Bloomberg later added that Visa and Mastercard have also signed up. The system is likely to use near field communication (NFC) technology, which transfers data to be transferred between a device and a reader when the two are held against each other. The iPhone 6 would therefore work in the same way as the contactless debit and credit cards which have recently entered circulation.
Sapphire crystal: the use of sapphire crystal (also known as sapphire glass) for the iPhone 6 screen has been one of the most persistent rumours about the new handset. Apple is known to have invested heavily in the super-strong manmade material, which is resistant to scratching and bending, but recent reports suggest that it has been having trouble making it in sufficient quantities – and at sufficiently low costs – to furnish an iPhone production run of 100 million units or more. The Guardian recently suggested that Apple may end up using a blend of glass and sapphire crystal.
A Liquidmetal shell: As Apple strives to make the new handset as slim and strong as possible, some commentators have speculated that it may turn to Liquidmetal, an alloy that's stronger than aluminium. In theory that would mean the handset could be lighter and slimmer without skimping on strength or build quality, but in practice it seems unlikely. Although one of the inventors of Liquidmetal predicted two years ago that Liquidmetal cases would be possible by mid-2014, its use has so far been limited to small components.
Liquidmetal components: This is much more likely. Documents published by Apple-watching website MacRumors, suggest that the alloy could be used in buttons and switches in order to toughen up what have often proved to be weak points on previous iPhones.
Aluminium frame: Although Liquidmetal may be off the cards, most of the leaked images and technical drawings suggest that Apple will adopt an all-metal rear frame for the iPhone 6. Previous iPhones have made either extensive or decorative uses of glass, but this year's preview shots appear to show a rear panel fashioned entirely from aluminium – with a cut-out for the Apple logo.
Super-slim frame: Whatever it's made from, most commentators expect the iPhone 6 to be noticeably slimmer than its already svelte predecessor. A few months ago some were predicting a depth of just 6mm, but specs supposedly leaked by Amazon in recent weeks suggest we can look forward to a 7mm iPhone. The slender dimensions are apparently causing problems for component-makers: the difficulty of making a battery that's just 2mm thick has reportedly led to production delays.
A8 chip: Concerted speculation that the new device would include a revamped processor has been "confirmed" by Venturebeat. "The A8 will run at a frequency of 2.0 GHz per core and will create noticeably faster response time and graphics rendering in the new phones," its source says. "By comparison, the A7 chips in the iPhone 5 run at only 1.3GHz per core." Even if those details prove wide of the mark, a newer, speedier chip is a safe bet: Apple is unlikely to build an all-new phone around old technology.
13-megapixel camera: There has been comparatively little speculation about the iPhone 6 camera, but tentative reports out today suggest that Apple may build in a 13-megapixels sensor capable of recording high-resolution 4K video. "Apple is well-known for investing millions into its camera sensor, though the company has always refrained from entering the megapixel count race because adding more megapixels tend to have an negative effect on the low-light performance," Tech Times says. But the website sounds a note of caution: "The original source comes from a Chinese web forum, which may not be the best place to find legitimate iPhone 6 leaked information."

Apple Store Crashes As iPhone 6 Goes On Sale

 

  Apple's website collapsed under increased traffic early Friday morning after eager customers waited until midnight to order the iPhone 6 and iPhone 6 Plus.

Users logging onto the online Apple Store at midnight — when the new iPhones were scheduled to go on sale — reported slow load times and a long delay in the devices becoming available to purchase.
Some service appears to have been restored after about 30 minutes. But later Friday morning, the store was down for some users. Its availability appeared to be intermittent.
Some customers reported that the iPhone was available on carrier websites and the Apple Store app but not the desktop site. There were reports that the iPhone 6 had sold out through some carriers, though when we checked on Apple.com, the iPhone 6 was available. The iPhone 6 Plus is not shipping for seven to 10 business days, or longer depending on the model you want.
The delays in the iPhone 6 becoming available in the online store frustrated many customers, as they had waited until the early hours of the morning to order the new phone.
The non-functional online store is the third glitch in a row to plague the launch of iPhone 6. At the launch event, the livestream failed for 25 minutes, leaving viewers staring at a fuzzy test-card and listening to commentary in Chinese. Then Apple delayed the iPhone 6 launch in China after failing to get regulatory approval on time (or, as conspiracy theorists would have it, the company wanted to punish its wireless carrier partners for leaking pictures of the new phones on their websites prior to the launch).
Of course, one might equally argue that the crashing web site illustrates the huge demand for the new phones — and is thus a good sign for Apple (and yet another piece of good publicity for Apple)

ABOUT COURSE
Computer Science engineering deals with design, implementation, management of information system of both Software and Hardware processes. While Information Technology deals with the use of Computers and Computer Software to convert, store, protect process, transmit, and retrieve information, Computer Science is a scientific and practical Approach to computation and its applications. The difference between Computer Science and IT is that while Computer Science deals with the design and development of new software and hardware parts of computer, IT aims at designing, developing, implementing and managing computer-based Information Systems including software applications and computer hardware. When Computer and Communications technologies are combined, the result is Information Technology, or ‘InfoTech’. A Computer scientist specializes in the theory of computation and the design of computational systems.

The quantum revolution is a step closer: New way to run a quantum algorithm

Theories show how computing devices that operate according to quantum mechanics can solve problems that conventional (classical) computers, including super computers, can never solve. These theories have been experimentally tested for small-scale quantum systems, but the world is waiting for the first definitive demonstration of a quantum device that beats a classical computer.
Now, researchers from the Centre for Quantum Photonics (CQP) at the University of Bristol together with collaborators from the University of Queensland (UQ) and Imperial College London have increased the likelihood of such a demonstration in the near term by discovering a new way to run a quantum algorithm with much simpler methods than previously thought.
The first definitive defeat for a classical computer could be achieved with a quantum device that runs an algorithm known as Boson Sampling, recently developed by researchers at MIT.
Boson Sampling uses single photons of light and optical circuits to take samples from an exponentially large probability distribution, which has been proven to be extremely difficult for classical computers.
Unlike other quantum algorithms, Boson Sampling has the benefit of being practical for near-term implementations, with the only experimental drawback being the difficulty of generating the dozens of single photons required for the important quantum victory.
However, the Bristol-UQ-Imperial researchers have found that the Boson Sampling algorithm can still be proven to be hard for classical computers when using standard probabilistic methods to generate single photons.
Dr Anthony Laing who led the CQP elements of the research said: "We realised we could chain together many standard two-photon sources in such a way as to give a dramatic boost to the number of photons generated."
Dr Austin Lund from UQ and currently on sabbatical in CQP added: "Once we had the idea for the boosted source, we needed to prove that it could solve a version of the Boson Sampling algorithm. We hope that the last major experimental hurdle has now been overcome.

Researchers advance artificial intelligence for player goal prediction in gaming

Researchers from North Carolina State University have developed artificial intelligence (AI) software that is significantly better than any previous technology at predicting what goal a player is trying to achieve in a video game. The advance holds promise for helping game developers design new ways of improving the gameplay experience for players.
"We developed this software for use in educational gaming, but it has applications for all video game developers," says Dr. James Lester, a professor of computer science at NC State and senior author of a paper on the work. "This is a key step in developing player-adaptive games that can respond to player actions to improve the gaming experience, either for entertainment or -- in our case -- for education."
The researchers used "deep learning" to develop the AI software. Deep learning describes a family of machine learning techniques that can extrapolate patterns from large collections of data and make predictions. Deep learning has been actively investigated in various research domains such as computer vision and natural language processing in both academia and industry.
In this case, the large collection of data is the sum total of actions that players have made in a game. The predictive AI software can then draw on all of that data to determine what an individual player is trying to accomplish, based on his or her actions at any given point in the game. And the software is capable of improving its accuracy over time, because the more data the AI program has, the more accurate it becomes.
"At some point that improvement will level off, but we haven't reached that point yet," Lester says.
To test the AI program, the researchers turned to an educational game called "Crystal Island," which they developed years earlier. While testing Crystal Island, the researchers amassed logs of player behavior (tracking every action a player took in the game) for 137 different players. The researchers were able to test the predictive AI software against the Crystal Island player logs to determine its accuracy in goal recognition. In other words, they could tell the AI everything a player had done in Crystal Island up to a certain point and see what goal the AI thought the player was trying to accomplish. By checking the AI's response against the player log, the researchers could tell whether the AI was correct.
"For games, the current state-of-the-art AI program for goal recognition has an accuracy rate of 48.4 percent," says Wookhee Min, a Ph.D. student at NC State and lead author of the paper. "The accuracy rate for our new program is 62.3 percent. That's a big jump."
