Free Web Hosting a Fount of Malware -ZDNet:

Web sites offering free hosting services are increasingly being used by hackers to store and distribute malware such as keyloggers, Trojan horse downloaders and spyware. These fraudulent, free personal Web sites have an average lifespan of two to four days, making them difficult to trace. One of the sites included music that accompanied a greeting-card message which runs while your computer is being infected.

Turn video into an animated cartoon -Amit Agarwal

Microsoft Research has invented a way to turn digital video into an animated cartoon. They've also developed techniques to combine animation with a still picture.

To define more meaningful regions, the user outlines the shapes on keyframes in the video, such as the pants on the girl swinging. He does this on several keyframes. "We rely on the user to circle things like the girl's pants. There's different shading on the pants, and some stripes. We can't group them automatically," said Cohen. The system can then interpolate between the keyframes, maintaining smooth trajectories along the time dimension, without jerky transitions or the need to draw on each frame.

The more complex the movements, the more keyframes the program needs to make the transition smooth. However, even the 300 frame video of the girl swinging on the monkey bars only needs a keyframe every 10 or 15 frames. By blending in the original pixels, the cartoon ends up being mixed - a real girl swinging through a cartoon landscape, or a cartoon girl swinging through a real landscape. The possibilities are endless.

In the future, the team would like to improve the user interface and make it possible to create other animation styles. They'd also like the program to work better with hand-held cameras. Unfortunately, it won't be on your computer store shelf anytime soon, though the researchers would like this eventually.

Structured Blogging -Rajesh Jain:
'Aggregation' in its current form means bringing a bunch of posts together from different places and showing them in a convenient way - usually either on one page, with three panes or two panes. Structured blogging is about letting the aggregator understand what you are talking about, and present things more intelligently. For example if you blog an event notification - maybe you're talking about a concert next week - it might be shown on a calendar along with everyone else's events.

Never underestimate the power of a good night's rest -Rajesh Jain:

SKIMPING on sleep does awful things to your brain. Planning, problem-solving, learning, concentration,working memory and alertness all take a hit. IQ scores tumble. If you have been awake for 21 hours straight, your abilities are equivalent to someone who is legally drunk.

Luckily, it's reversible - and more. If you let someone who isn't sleep-deprived have an extra hour or two of shut-eye, they perform much better than normal on tasks requiring sustained attention, such taking an exam. And being able to concentrate harder has knock-on benefits for overall mental performance. Attention is the base of a mental pyramid, if you boost that, you can't help boosting everything above it.

Blocking Visual Spam -Hindu

SeeFree has rolled out its `Visual Spam Blocking System', which uses technology to filter out `visual spam.' SeeFree spectacles provide users with the ability to see the world as it would look — without billboards, signs and other commercial visual spam, thus allowing the user to focus only on the objects that he wants to see. The spectacles, resembling cool sunglasses, are fitted with an electronic binocular see-through device.

Its `brain' is a sophisticated microprocessor system that processes all visual information in your sight, in real time. This `image recognition system' can distinguish billboards, advertisements and the like from other visual elements. After the system has recognised the `unwanted' elements, it creates a `floating mask' according to their shapes to be overlapped to the actual view. In order to make the masked elements less contrasting and distracting, the system calculates the colour and brightness of the mask as an average to the surrounding areas.

Someone's checking up on you -ZdNet

Before you join an IT company, your past life will be probed thoroughly. V Narayan (name changed), 30, returned from the US and applied for a job at a Fortune 500 IT company in India. With impeccable credentials, he almost landed a project leader's post. But he had not told his future employer that he had been arrested for child molestation in the US. Narayan had assumed that the Indian company would never find this out. But it did. It had entrusted the task of screening him to Mumbai-based background screening company Quest Research.

What is checked...
  • Your general education background. Companies call up the university where you studied for your bachelor's or master's degree and check the records.

  • Your professional degree or certificates. Ditto, but this relates to your MBA degree or any certificates you may have obtained. The first point that's checked is whether your university is a recognised one.

  • Employment history. Companies call up all the companies you had worked for. Companies don't call the people you have given as references because these may be your friends. Instead, they call the HR department or others.

  • Criminal check. Companies check with the local police station and so on.

  • Address. Companies check whether you are staying at the address you mentioned in your application. They talk to your neighbours and so on.

The large IT companies now spend anywhere between Rs 3,000 and Rs 6,000 per candidate, while mid size companies shell out between Rs 1,000 and Rs 2,000 per candidate

Investigations in India can take anywhere between 4 and 15 days per candidate. That's because information on individuals is not available at one place in India, unlike in the US where the social security number can provide leads on a person. 7 separate documents, ranging from the passport and driving licence to the ration card, identify an individual in India. Except for the passport, every document can be easily bought.

Google Translator: The Universal Language:
At the recent web cast of the Google Factory Tour, researcher Franz Och presented the current state of the Google Machine Translation Systems. He compared translations of the current Google translator, and the status quo of the Google Research Lab’s activities. The results were highly impressive. A sentence in Arabic which is now being translated to a nonsensical “Alpine white new presence tape registered for coffee confirms Laden” is now in the Research Labs being translated to “The White House Confirmed the Existence of a New Bin Laden Tape.”

How do they do that? It’s certainly complex to program such a system, but the underlying principle is easy – so easy in fact that the researchers working on this enabled the system to translate from Chinese to English without any researcher being able to speak Chinese. To the translation system, any language is treated the same, and there is no manually created rule-set of grammar, metaphors and such. Instead, the system is learning from existing human translations. All it needs is someone to feed the system the two books and to teach it the two are translations from language A to language B, and the translator can create what Franz Och called a “language model.” This is brute force AI, if you want – it works on statistical learning theory only and has not much real “understanding” of anything but patterns.

Now comes the exciting part. This translation system can have numerous applications. Apart from the usual 'website translation' services, it could be used in more advanced applications like Instant Messengers and Babelfish-It would be a smart device you plug-in to your ear, and it would have speech recognition and Auto-translation built in. You can now visit a foreign country and understand people who talk to you in languages you never learned. While the needed text-to-speech and speech-to-text technologies are far from perfect at the moment, they are still realistic possibilities.

Miscreants encrypt files, hold them for ransom -ZdNet

In a new type of online attack, extortionists remotely encrypt user files and then demand money for the key to decode the information. The attack occurs after a user visits a Web site containing code that exploits a known flaw in Microsoft's Internet Explorer Web browser. The flaw is used to download and run a malicious program that in turn downloads an application that encrypts files on the victim's PC and mapped network drives, according to Websense. The program then drops a ransom note.

Attackers could use e-mail, a Web site, or other means to distribute the Trojan.Pgpcoder and launch a widespread extortion campaign. Attackers leave a trail if they ask for money. This type of attack is not that difficult to perform. However, in order to collect money the attackers are leaving themselves open to investigation and tracing.

China's way ahead of India on software piracy list -The Economic Times:
India with 74% piracy rate has managed to slip out of the list of 20 countries with the highest incidence of software piracy, despite a 1% increase in piracy rate. China, with 90% piracy, occupies the third slot — after Vietnam and Ukraine leading with 92% and 91% piracy rates, respectively.

In India, it’s corporate end-user piracy where small and medium segment businesses use unlicensed software that is a constant worry. For every two dollars worth of software purchased globally, one dollar worth was obtained illegally.

Go up the value chain or perish -ZDNet:
There's definite evidence of India excelling in the IT industry. But within this vast spectrum of IT services, including consulting, ITES, application development, what can be called India's niche area of expertise?

India needs to identify an area of specialisation in the face of rising competition from countries such as Russia, the Philippines and China. We need to excel in providing a certain category of goods and services, so we do not lose our footing when the eventual exodus starts - of countries shifting their outsourcing requirements to nations which have a definite cost advantage over India in terms of lower labour rates, better infrastructure and less red tapism.

With India having captured only 0.2% of the $180 billion global software product development market, there is still a long way ahead for us. Offshoring in the early 1990s began with product development, and not IT services. In the mid 1990s, the focus shifted to outsourcing IT services.

Microsoft tries to breathe life into older PCs -Zdnet:
Code-named Eiger, the product is basically designed to turn older PCs into a thin client, which is a terminal that gets most of its information from a central server. Unlike traditional thin clients, though, a few programs can be run locally, including Internet Explorer, Windows Media Player and antivirus software.

Microsoft is pitching the software at customers who can't or don't want to buy new PCs, but are concerned that their older computers are not secure and hard to manage. Under the hood, Eiger is a hybrid of Windows XP with Service Pack 2 and Windows XP Embedded.

An Adobe killer from Microsoft -Digit Mag

Adobe may have killed the competition in online publishing by acquiring Macromedia. But Microsoft is not keeping quite. The next version of Windows will include a new document format, code-named "Metro," to print and share documents. Metro appears to rival Adobe's PostScript and PDF technologies.

The format, based on XML (extensible markup language), will be licensed royalty free and users will be able to open Metro files without a special client. In the demonstration, a Metro file was opened and printed from Internet Explorer, Microsoft's Web browser.

The Metro technology is likely to go head-to-head with Adobe's PostScript technology. "It is a potential Adobe killer", said Richard Doherty, research director with The Envisioneering Group in Seaford, New York. "But this is just the first warning shot. Adobe could put something that is even more compelling Longhorn.

ASPs failed ? But are now making a comeback -ZDNet:
Some five to six years ago, Application Service Providers (ASPs) were one of the hottest categories in software. They would transform the way software would be delivered and create a win-win situation for customers and software vendors. That dream did not pan out.

ASPs offer applications over the internet using their own servers to customers, who pay a regular fee for the use. For companies, there is no need to own either the application or the underlying infrastructure.

For service providers, it helps them aggregate a large number of customers, providing economies of scale. Using the internet as the distribution medium, ASPs can reach out to customers globally.

ASPs in many respects presented a false start in the efforts to break out of the enterprise straitjacket. In particular, few of them adopted Web services architectures as their technology platform. Instead, they attempted to build businesses on the internet using traditional technology architectures. This proved a significant flaw in the early ASP model.

The big opportunity for ASPs is the long tail of enterprises in the world's developing countries. They have been largely unaffected by the internet - other than email usage and in some cases have a minor web presence.

Advertising revenues of Google + Yahoo > TV ads
This year the combined advertising revenues of Google and Yahoo! will rival the combined prime-time ad revenues of America's three big television networks, ABC, CBS and NBC, predicts Advertising Age. Both Google and Yahoo! make most of their money from advertising. Auctioning keyword search-terms, which deliver, along with their own search results, sponsored links to advertisers' websites, has proved to be very lucrative. Advertisers like these links because, unlike with TV ads, they pay only for directly measurable results. They are charged when someone clicks through to their own website.

And here's a key to combat hacking -The Economic Times:
David Pearson, a division scientist at the Massachusetts-based BBN Technologies is already trying his hand at building an unhackable network. And thanks to quantum cryptography, it is possible.

It harnesses quantum physics to create encryption keys that are all but impossible to crack because they are rendered useless by simply looking at them. The keys are made from tiny bits of light called photons. Even when assuming hypothetical eavesdroppers with unlimited computing power, the laws of physics guarantee that the secret key exchange will be secure, given a few other assumptions.

Google enhances search for Firefox users -ZDNet:
Google has added a new feature to its search engine that allows Firefox users to obtain search results more quickly. The search engine's preloaded link feature is supported by Mozilla browsers, including Firefox, but because Microsoft's Internet Explorer and other browsers do not provide such functionality, they will not be able to use the feature.

When you do a search on these browsers, we instruct them to download your top search result in advance, so if you click on it, you'll get to that page even more quickly.

There are some potential issues, however. "You'll run into trouble if the first match is a porno site and your company's proxy logs it-you get all cookies of the first match without seeing the page",one Firefox user said. Another user adds,people may unknowingly download illegal content.
