The Indian arm of the US-based IT giant IBM has introduced this new protocol called Hyper Speech Transfer Protocol which is s imilar to HTTP which is hypertext transfer protocol. This HSTP protocol actually lets the user to talk to it. All these web pages can be accessed us ing mobile phones and voice sites can be created. This protocol was mainly created for the people who can’t read where their voices alone are enough for carrying out the necessary task. It also provides services like paying using credit cards over the phone with the security pathway. We could say it’s another thing like talking to customer service, only here we’d be using the internet.For business oriented people, who have to travel long distances, and they need to buy something, they just have to use their mobile phones, like Jo nathan here. Jonathan is a busy sales man who travels frequently. His work typically requires him to stay in a place for a few days. Once he is in a new place, he has to go around looking for grocery stores in his locality for his daily needs. He prefers ta king phone numbers of the identified stores and places orders on the phone s ubsequently. Home delivery services deliver the goods to his home. However, often the home delivery boys don't accept credit cards and even if some do, Jonathan tries paying by cas h since he does n't want to s hare his credit card information with untrusted home delivery agents. This often causes problems since he often runs out of cash. During his travel, he visits a city and finds out that there is a yellow pages service in the city that he can call up to receive phone numbers of several bus inesses. He promptly calls up the service and uses the telephony voice application to browse through the grocery stores. On Jonathan's prompt, the call gets transferred to a grocery store and goes to the voice application of the store. Jonathan easily specifies the items he needs to buy from the cataloger. The order is placed and a delivery guarantee is made within half an hour To his surprise, the grocery store's voice application also accepts credit cards securely over phone. Jonathan selects the option and his call gets transferred to yet another voice application of a secure payment gateway. The secure payment gateway already knows about the amount of money the grocery store wants to charge to Jonathan, and securely authorizes the payment by taking in Jonathan's credit card details and transacting with the credit card company's authorization system. It is a very interesting piece of news indeed, imagine talking to the websites. Maybe this is just the stepping stone for something more that might come to exist in the mere future. If our world does indeed ends up being destroyed I’d say we’ll end it in style. Laugh-O-MaNIA February’09 Issue ~ What is a computer's first sign of old age? Loss of memory. ~ What happened when the computer fell on the floor? It slipped a disk. ~ My computer isn't that nervous. It's just a bit ANSI. ~ It says: "Press Any Key" It means: "Press any key you like but I'm not moving." ~ It says: "Please Wait...." It means: "...

For years, consumers have been sold digital cameras largely on the basis of one number – the megapixels crammed onto its image sensor. But recently an industry bigwig admitted that squeezing in ever more resolution has become meaningless.Akira Watanabe, head of Olympus' SLR planning department, said that 12 megapixels is plenty for most photography purposes and that his company will henceforth be focusing on improving colour accuracy and low-light performance. That will surely raise the quality of most home snaps, but his admission suggests something much bigger for the future of photography. As most of the technological hurdles of capturing still and moving images on consumer-grade cameras have been met, the real frontier of innovation now lies in what happens to images after they have been captured. New dimensions Already we are seeing how powerful software tools are making still photos just an intermediate on the way to something more interactive. One example, Microsoft's Photosynth, which organises collections of photos of the same scene as a 3D space. It's an approach that can be more easily understood by watching video of it in action. The latest project on Photosynth meshes photos into an almost seamless 3D environment in which you can even walk inside buildings. The way Google Street View presents realistic views of the world using linked still images is another example of the potential of this kind of technology. Gigapixel gains A recently released robotic tripod called Gigapan that makes it much simpler to stitch together incredibly large, detailed images from hundreds or thousands of individual shots, puts new powers in amateur hands. The technology is also helping scientists to record vulnerable environments, or create super-accurate photographic archives. Another technique, dubbed super resolution, combines multiple photos to reveal detail not visible in any of the originals. One-click methods to make a face in a photo more attractive, or turn 2D photos into realistic 3D models are also now possible. Special effects And it's not just stills photography that is benefitting from advances in tech. Sites like YouTube have got us used to the idea that anyone can edit and share a rough and ready video, but the tricks of Hollywood studios are also being democratised. Researchers from the Weizmann Institute of Science, Israel, have made a package that lets you edit the surface of objects in a movie just once and have the changes persist throughout the footage – with more traditional techniques, every frame would have to be edited. Software firm Adobe is working on a similar package that also makes it possible to move objects inside a movie with just a few clicks. Smart software can make previously unthinkable post- production techniques available to anyone. So, in the future, our cameras will no longer merely provide snapshots and footage to be viewed in the traditional ways – increasingly, their output will be aimed at feeding software and online tools that roll them into novel ways to experience photography. The basics of capturing images will still undergo gradual evolution, but for a technological revolution we should look to the software that works on a camera's output. MIXED BAG February’09 Issue 1.

The ransom note told him to bring a valuable diamond to a phone booth in the middle of a public park. Plainclothes police officers surrounded the park.The rich man arrived at the phone booth and followed instructions but the police were powerless to prevent the diamond from leaving the park and reaching the crafty villain. What did he do? This is a true story from Taiwan. When the rich man reached the phone booth he found a carrier pigeon in a cage. It had a message attached telling the man to put the diamond in a small bag which was around the pigeon's neck and to release the bird. When the man did this the police were powerless to follow the bird as it returned across the city to its owner.
