The school of tomorrow


Every year Ashish Rajpal teaches science for fourth or fifth standard students at a school in Delhi. Not exactly business as usual for an MBA and the managing director of a company. But then teaching is Rajpal's business at iDiscoveri and it was a similar stint of teaching fourth graders that laid the foundations of his popular XSEED programme a few years ago.

“I came back after doing my M.Ed. at Harvard University eight years ago, with this crazy mission to change education in India,” says Rajpal, an MBA from XLRI. “Given that we have six million poorly trained teachers in India, I dove right into teacher training, but found that in itself did not change classroom practice or help the children.”

That's when Rajpal himself started teaching science at a Delhi school. “And I found it's incredibly tough to teach 45 children in a crowded classroom!” he says. “I realised that all this theoretical nonsense we'd been feeding the teachers meant nothing in a real-world situation. We needed something that worked in the classroom.”
The result was that iDiscoveri began to create minute-by-minute plans for the teacher to follow in class, including group work, experiments and other forms of experiential learning. And so XSEED was born. “Today we've created over 8,000 lesson plans across all subjects for nursery to seventh standard, and XSEED reaches 450 schools across the country,” says Rajpal. “We're hoping that number will reach 1,000 by next summer.”

About a hundred of those schools are right here in Tamil Nadu, which is one of XSEED's flagship states. “Although we started in 2002 in Delhi, we found that the South was far more receptive to our ideas,” he says. “So we decided to focus on Southern states, and picked Tamil Nadu and Andhra Pradesh.”
Rajpal describes the programme of getting into the schools, and doing not just lesson plans, but also teacher training and quarterly assessments of students as a “sort of stock market report. But then that's Rajpal for you — a mixture of starry-eyed idealism and businesslike pragmatism.

“I am an idealist at heart — I'd have to have been, to give up my well-paying corporate job in Paris, uproot my family and go do my M.Ed. at the age of 31,” he says. “But my corporate experience for 10 years has also shaped me. Ideas aren't enough — you have to make it work.”
He recalls how he applied in secret to Harvard, inspired by the birth of his children. And once there, he was “like a greedy hog”, making the most of the opportunities before him. “Intellectually, those were the best years of my life — I was getting to hang out with legends such as Howard Gardner and David Perkins,' he says.To ensure these ideals aren't lost, iDiscoveri launched The School of Tomorrow conference here in Chennai last year, with the second, bigger edition around the corner (see box). Then there's the leadership programme for young adults Rajpal's working on, along with supplementary programmes to meet different needs of students and a national network of XSEED centres. And, he's considering diversifying to teaching English as well. It's all in a day's work for this educational entrepreneur.

Sony launches world's first tilting TV


Electronics giant Sony has launched what is being billed as the world''s first television with a screen which can be tilted backwards, which the company says is optimum for comfortable viewing.

Apparently, a slight backwards lean of six degrees is now the best position for a TV set as many of us mount modern flat-screens on furniture a foot or two above the ground.

The new range can be slotted into the tilting position to achieve what its makers say is the optimum picture, as we slump down on our plush, comfortable sofas.


It comes as design experts say we are increasingly choosing glossy, shiny TV screens which complement our homes' style even when they are switched off, reports the Daily Mail.

The 'Monolithic' TV screens, priced at 1,300 pounds for a 40-inch screen, are available in state-of-the art 3D models, and can either be set up vertically or slotted to a six-degree backwards lean.

"Most people don't put their televisions at waist height any more, they set them up a foot or two off the ground, said Tim Page, Sony Europe's senior manager of technology marketing.

Sharp to launch 3D phones in India, China and U.S. in 2011


The world is taken over by 3D and its touching our lives through movies, TVs and now mobile phones. While 3D renders more life to everything its in, the glasses required to view a 3D image not only affects the fashion conscious, it also affects your comfort level. Now there is a solution to wearing the 3D glass woes as well.

Sharp, the Japanese electronic product manufacturer is launching a mobile phone with a 3D display screen. The catch here is that you won't require glasses to view the mobile screen. Sharp had released two such phones in the Japanese market in the recent past. And as per reports, Sharp will bring the handsets to India, U.S. and China markets in 2011.


The device runs on Android operating system (Froyo) with the screen used is the same as that used in Nintendo 3DS, displaying 3D content sans glasses. With a display screen size of 3.8 inch, the phones are powered by 1GHz Snapdragon processor. Sharp has named the models the Galapagos 003SH and 005SH. While the former has a 9.6MP camera, the latter has a QWERTY keyboard and an 8MP camera.

Motorola making available free Indian maps for Android- powered handsets


The owners of handsets like Milestone, Milestone XT720 and the Backflip can access any Indian map for acquiring information about cities, towns and villages spread across the country entirely because they function on Google’s mobile operating system. The Android powered Motorola handsets have been designed as the perfect travel companion.

Not just the cities, towns and villages but this feature also offers voice- guided street-level navigable MapmyIndia maps for users who require information about numerous lanes and major national and state highways of the country.


“We believe in offering the latest to our consumers in India. The new maps are more detailed and include information such as business districts, offices and market locations. Navigate on Motorola’s Android-powered handsets across 620 cities in India for a truly enjoyable experience,” remarked Faisal Siddiqui, Country Head, Motorola Mobility India.

The most attractive part of these Android powered handsets is that they can provide this navigation service without installation or data charges. The users just need to open Motorola’s MotoNav application for launching the maps on their systems. Any mobile network can be used and there is no requirement of a SIM card.

Notion Ink's, Adam tablet shows off its app on its blog


We've been waiting for the Notion Ink logo to debut, but it seems like it's run into a little problem. Apparently, some other company's registration page bears a very similar logo, and where the creator of the winning Notion Ink logo could not have seen this, the similarities are enough to give it a second thought.

Other details have been revealed about some of the Android-powered applications that will ship with the Adam, including GPS navigation software, email application, and file manager.

Little was said about the GPS navigation software. We know it will differ from the GPS navigation features baked into Android, but we're told little else. What we do know is that the GPS software has recently entered beta status and already speaks in 43 languages. Pretty impressive for beta, no? We can expect to see more languages added later on, hopefully.

The email application, Mail'd, will come with many features you're already used to seeing, and more. Some of these features include missing attachments, offline mode, and unsend an email. It's said that even more features will hit Mail'd come January, and you can expect to see things like how big an attachment within an email can be, email expiration times, and fixing the time of delivery of an email while in offline mode.

Another highlighted application is Sniffer, which is said to be an, "extremely fast and handy File Browser". This isn't the final version of the application, but the preview definitely showcases the panel feature that the Adam will boast, and it's looking pretty good.

The blog also gives some details concerning the Adam's screen, and some of the issues they've come across with the particular matte finish of the screen. These matte screens show degradation and displacement of green pixels, and the Notion Ink team have put forth major efforts to overcome this issue. We're told that we won't be disappointed. We hope not, especially since we've been waiting for some time now.

India to develop electronic warfare system soon


India is developing its own radar-based electronic warfare system (EWS) with two test ranges in Karnataka and Andhra Pradesh to equip its armed forces for modern wars, a senior defence official said Wednesday.
"An indigenously developed radar-based EWS will be ready by 2013, with test ranges at Chitradurga in Karnataka and at Tandur near Hyderabad in Andhra Pradesh," state-run Defence Research and Development Organisation (DRDO) chief controller Prahlada said here.Cost of each test range is estimated to be about 200 crore.
Noting that modern day wars cannot be fought and won without EWS, Prahlada said the radar-based sophisticated communication system would use electromagnetic spectrum for attack, protection and warfare support to destroy the combat capabilities of an enemy.
"The prowess of electronic warfare system was amply demonstrated by the U.S. armed forces in Iraq and Afghanistan. A prototype EWS has been integrated with MiG-27 fighter for test flights," Prahlada said at the first India National Electronic Warfare workshop, organised by the India chapter of Association of Old Crows (AOC), based at Virginia in the U.S.The Chitradurga aeronautical test range, which will come up by 2012 at the DRDO's 4,000-acre campus in the state, about 200 km from Bangalore, will be used for communication-based EWS and the Tandur range will be used for non-communication EWS.
"The testing centres will be operational by 2012. As per the plan, EWS will be integrated with MiG-29, Jaguar, Sukhoi-MKI-30 of the Indian Air Force (IAF) and the indigenous Light Combat Aircraft (LCA) Tejas by 2011," Prahlada told about 300 delegates.
"Our goal is to develop the fourth-generation EWS by 2012 because without electronic warfare, you cannot win a war. Once you have it (EW capability), you have to test it, you can't wait for a war to test it," Prahlada added.The fourth-generation EWS is being developed by the state-run Defence Avionics Research Establishment (DARE) and Defence Electronics Research Laboratory (DERL).Once the air version of EWS is integrated and operational, the naval and army versions will be developed simultaneously.Currently, EW systems are being tested in the IAF range at Gwalior in central India.Stressing on greater self-reliance in production and procurement, the defence scientist said the country's defence research and development (R&D) establishments have been able meet about 50 percent of defence requirements indigenously and the target was to scale it up to 70 percent by 2020.

Army test-fires Agni-I as part of user trial


India on Thursday test-fired its Agni-I strategic ballistic missile, with a range of 700 km, as part of the Army’s user trial from the Integrated Test Range at Wheeler Island off Orissa coast.The indigenously developed surface-to-surface single-stage missile, powered by solid propellants, was test-fired from a rail mobile launcher at 10.10 a.m. from launch pad-4 of the ITR, 100 km off the Orissa coast, defence sources said.User of the missile — the Strategic Force Command (SFC) of the Indian Army — as part of their training exercise, executed the entire launch operation with the logistic support provided by the Defence Research Development Organisation (DRDO) at the ITR, said a DRDO official.The missile has a highly specialised navigation system which ensures it reaches the target with a high degree of accuracy, he said.
The entire trajectory of the missile, which has an operational striking range of 700 km, was tracked by sophisticated radars and electro-optic telemetry stations located along the sea coast and two ships positioned near the impact point in the downrange area.Weighing 12 tonnes, the 15-metre-long Agni-1, which can carry payloads up to 1000 kg, has already been inducted into the Indian Army.Agni-1 was developed by the Advanced Systems Laboratory (ASL), the premier missile development laboratory of the DRDO in collaboration with the Defence Research Development Laboratory (DRDL) and Research Centre Imarat (RCI) and integrated by Bharat Dynamics Limited (BDL), Hyderabad.The last trial of Agni-1 missile was successfully carried out on March 28, 2010 from the Wheeler Island.Since the missile has already been inducted into the Army, it is important to conduct user trials for training of defence personnel and improvement of their skills, sources said.

Simultaneous signals from 2 pulsars heralds new era in radio astronomy


The mobile number portability (MNP) is finally launched in India today. Rohtak in Haryana is the place where the entire buzz is. Rohtak is witnessing a telecom revolution today. MNP is the procedure that allows consumers to switch from their existing operators to another while retaining the same number.

With Idea Cellular's TVCs on air for few days now, other operators are also coming up with their own promotions of MNP through various media. On the occasion of the MNP launch in India, we share with you the process and other facts of MNP.First the procedure. To change your operator all you need to do is send a SMS to 1900 with the message (PORTMobile number) from the number you want to be ported. On sending the message you will receive a SMS from your current operator giving you the Unique Porting Code (UPC). The UPC acts a reference when you fill an application prescribed by your chosen new network provider. The porting of number has to be completed in a span of seven working days, as per TRAI directives. The charge for porting your number to another operator is 19, payable to the new service provider. Post-paid subscribers need to ensure their billing dues are cleared before applying for number porting. Failing this, the request to the new porter will be rejected. For pre-paid users, the balance amount left does not get carried forward to the new operator after porting. So both kinds of subscribers start from a clean slate with the new operator.A point to note here is once you have switched your operators, you need to wait for a period of 90 days before you can change the operator again.

Let us give you a brief idea about how the MNP works. When a subscriber makes a request to port his number to a new operator, the porting can be done in two ways. One is called the donor-led porting and the other is recipient-led porting. In India the latter method is in usage.

In the recipient-led porting, the new operator (recipient) takes the appropriate steps to register the user to its network. The process is completed once the mobile number of the user and the chosen operator's network ID are paired and updated in the central database. The country is divided onto two geographical sectors for ease of implementing the MNP. These two zones are then divided into 11 service areas.

The master database will be managed by a third party firm. For zone I, Syniverse has been appointed with the MNP and related issues while for zone II, it is Telcordia. With this set of information, we hope the MNP will be a good thing for the nation that is heralding its gears to the new technologies and embracing them with open arms.

Microsoft unveils controller-free gaming device for Xbox 360

Microsoft on Wednesday launched the new ‘Kinect' interface for its Xbox 360 gaming device that allows users to play games with their body movements instead of a conventional joystick.

‘Kinect' senses users' movements and lets them play games without using a joystick with the help of an embedded RGB camera, depth sensor and microphone.

“Kinect has not only revolutionised gaming, but has the potential to introduce applications spanning areas like health and education. This is the next era in the evolution of human interface with computers and beginning the move from graphical user interface to natural user interface,” Microsoft India Regional Director (Entertainment and Devices Division) Jaspreet Bindra told reporters here.

Xbox 360 4GB consoles with a Kinect sensor and a free 'Kinect Adventures' game will be available in stores for Rs 22,990, he added.For people who already have an Xbox 360 console, the standalone Kinect sensor and ‘Kinect Adventures' game would be available at a price of Rs.9,990.Microsoft has sold about 45 million Xbox 360 consoles globally.

There are 11 Kinect games available for the Xbox 360, in the genres of sports, adventure, fitness and dance.

How sharks change directions while moving at full speed


A new study has suggested that one of the evolutionary secrets of the shark’s success hides in one of its tiniest traits-flexible scales on the bodies of these peerless predators.
The study by University of South Florida has suggested that these scales make them better hunters by allowing them to change directions while moving at full speed.
The key to this ability lies in the fact that the scales control water flow separation across the creatures’ bodies, said Amy Lang of the University of Alabama.
separation is an issue in systems like aircraft design, explained Lang, because it tends to cause vortices that impede speed and stability. “In nature, if you look at surfaces of animals, you’ll see that they are not smooth.” she said.
“They have patterns. Why? One common application of patterning a surface is to control flow-think of the dimples of a golf ball that help the ball fly farther. We believe scales on fast-swimming sharks serve a similar purpose of flow separation control,” she added.
Based on experimental measurements and models of shark scales, Lang’s team discovered that the bases of shortfin mako scales (literally small teeth covering their body) where they attach to the skin are not as wide as the tops of the scales.
This tapered shape enables the scales to be easily manipulated to angles of 60 degrees or more, endowing them with movement called “denticle bristling”. Also, these flexible scales are only found on parts of the body where flow separation is most likely to occur, such as behind the gills on the side of the body. The findings were presented at the American Physical Society’s Division of Fluid Dynamics (DFD) annual meeting in Long Beach.n.

Facebook messaging may soon doom you


Bangalore: Computer security firm Sophos warned the Facebook users on their usage of online messaging services. It is being found that such uses of the social networking site are now more vulnerable to identity theft by cybercriminals.

A serious vulnerability in Facebook's security allows anybody who has your mobile phone number to not only change status messages, but also add or delete friends, send out private messages to other users and upload or change profile pictures. However, the security flaw only affects those who have activated Facebook Mobile, a facility that allows the user to send updates on the social networking site through text messages from a mobile phone."Users need to realize that these new features increase the attack surface on the Facebook platform, and make personal accounts all the more alluring for cybercriminals to break into," said Sophos senior technology consultant Graham Cluley.

Facebook's new messaging system was launched on Monday and includes facebook.com email addresses. Approximately 350 million of Facebook's more than 500 million members fire off messages using its existing service, with more than four billion digital missives sent daily.

Sophos noted that fraudsters are increasingly using hacked Facebook accounts to send spam messages compared with traditional emails because they are more likely to be opened by recipients lured to think the messages came from friends. Sophos also urged the users to be aware of the security risks before signing up for Facebook's next-generation online messaging service that blends online chat, text messages and other real-time conversation tools with traditional email.

Now you can log in to MySpace via Facebook


Silicon Valley: After passing almost a year filled with rumours, MySpace has accepted that it has lost it in the social networking race and its useless in trying to catch up. Thus, in order to save the website, MySpace along with Facebook announced in a press conference about the enabling of a Facebook button on the MySpace homepage. 'Mashup', as it's called, with Facebook feature enables personalization and sharing features on the website.This move made by MySpace is quite significant as it has finally acknowledged Facebook to be the ruling king of the social networking sites and because of the new feature, there are chances that Facebook can bring back the social networking frenzy people in a fair amount to MySpace. Facebook is very much capable of creating a huge new audience and has the potential to boost MySpace's number significantly with its new feeds being the extreme source of news and entertainment.

"We are thrilled to further our collaboration with Facebook through Mashup with Facebook," Mike Jones, CEO of MySpace, said in a statement. "This new feature is a great illustration of our strategy around social entertainment and enabling the real-time stream. The stream is one of our most popular features on MySpace, and it is now delivering an even richer entertainment experience of relevant content for our users to enjoy. "I'm particularly excited because so many people will be able to have the immediate satisfaction of enjoying their own entertainment program that they have customized themselves as well as connecting to all their passions and to the MySpace community at large."

Same as Facebook, MySpace has plans to bring out 'Like' buttons for the content like music and videos which will be shared back to facebook. MySpace is currently playing safe; they just need to continue the same way by getting their content strategy correct.
