Google Body Browser

Google has launched a new educational tool called Google Body Browser. Launched on the Google Labs website today, Google Body Browser uses HTML5 technology to let you examine the human body in fully layered, three-dimensional detail.

The application uses WebGL, a plug-in-free programming interface, to power its 3D graphics. WebGL is a relatively new standard, and most major browsers are still testing its implementation. For now, you can grab the latest beta version of Chrome or Firefox to check it out; eventually, the stable versions of those browsers (and most others) will offer integrated WebGL support.

chrome 9 released

Google has just released Chrome 9 beta. Chrome 9 comes with many new features, unlike Chrome 7 and Chrome 8.
Chrome 9 Beta comes with the following features:

The Adobe Flash plug in has been sand-boxed.Carlos Pizano,software engineer at Google explains, "The sandbox adds an additional layer of protection to further guard against malicious pages that try to hijack your computer or steal private information from your hard drive." The sandboxed Flash Player has been released on Chrome for Windows only, but will be released for Linux and Mac soon. 

  One more important feature of chrome 9 is that it includes WebGL support by default.WebGL is a revolutionary new Web technology that brings hardware-accelerated 3D graphics to the browser without installing additional software

WebP: Google's new image format

Google has released a new image format called WebP, pronounced as "WEPPY" which reduces your size, bandwidth and hosting costs for images.This new image format reduces the file size by 40% compared to JPEG without compromising the quality. Also Google has  open sourced this format.
WebP is a method of lossy compression that can be used on photographic images. The degree of compression is adjustable so a user can choose the trade-off between file size and image quality.

A WebP file consists of VP8 image data, and a container based on RIFF. Webmasters, web developers and browser developers can use the WebP format to create smaller, better looking images that can help make the web faster.
Working of WebP

WebP uses predictive coding to encode an image, the same methodology used by the VP8 video codec to compress keyframes in videos. Predictive coding uses the values in neighboring blocks of pixels to predict the values in a block, and then encodes only the difference (residual) between the actual values and the prediction. The residuals typically contain many zero values, which can be compressed much more effectively. The residuals are then transformed, quantized and entropy-coded as usual. WebP also uses variable block sizes.

Vodafone announced that it is all set to bring the iPhone 4 to the Indian market in the coming months.

NETRA:Tool for Refractive Assessment

THE HUMBLE mobile phone is soon going to be your ophthalmologist. You will be able to self-test your eyesight just as you check your body temperature, blood pressure or blood glucose using digital devices. All you will need to do is run a simple application on your phone, look at the screen through a tiny attachment and press a few keys.

And within seconds, you will have the status of your eyesight on your phone's screen. This is an innovative piece of technology developed by a group of researchers led by India-born Ramesh Raskar at the media lab of the Massachusetts Institute of Technology (MIT).

It has yielded encouraging results and will soon be field-tested in India in collaboration with the Hyderabad-based L. V. Prasad Eye Institute.

The device has been named NETRA or Near-Eye Tool for Refractive Assessment. The device has the potential to make routine eye-testing simpler, cheaper and accessible to millions of people. It takes advantage of the huge improvements in the resolution of digital displays and their widespread proliferation on mobile phones, which have become ubiquitous in developing countries.

NETRA currently works with phones having high-resolution displays. But researchers are expanding the range of phones that it can work on and are also developing pattern designs that can work with low-resolution phones.

"You can think of it as a thermometer for visual performance. Just as a thermometer measures corporal temperature and does not prescribe medicine, NETRA measures the refractive error and does not necessarily prescribe glasses," says Raskar, who heads the Camera Culture group at the media lab. "It allows a user to self- assess the performance of his or her eyes over time. The goal is to empower people, not replace optometrists."

Apart from the software to run on the phone, all that's needed is a snap-on plastic device, which, researchers say, can be produced for about $2 (about Rs 93). But it would cost much lesser if produced in large quantities. The plastic device can be clipped on to the front of a cell phone's screen.

The micro-lens array in front of the LCD essentially creates a 4D display. The user looks into a small lens and presses the phone's navigation keys until sets of parallel green and red lines overlap. This is repeated eight times, with the lines at different angles, for each eye.

The whole process takes less than two minutes, at which point the software loaded on to the phone provides the prescription data. The prototype developed by Raskar's team has an array of tiny lenses and a grid of pinholes that, combined with the software on the phone, forces the user to focus at different depths.

Swype: a software that predicts words as you glide across your keyboard

Seattle-based Cliff Kushler,the man  who invented the T9 software for quick typing on cell phones, has created yet an another path breaking software called  Swype with partner Randy Marsden which predicts words as you slide your fingers on the keypad.

Swype allows users to glide a finger across the virtual keyboard to spell words, rather than tapping out each letter.

"We've squeezed the desktop computer, complete with keyboard and mouse, into something that fits in a pocket. The information bandwidth has become very constricted. I thought, if we can find a better way to input that information, it could be something that would really take off," the New York Times quoted him as saying

He said that Swype is a big breakthrough that could reach billions of people.
Swype's software detects where a finger pauses and changes direction as it traces out the pattern of a word.The movements do not have to be precise because the software calculates which words a user is most likely trying to spell.Capitalization and double letters can be indicated with a pause or squiggle, while spacing and punctuation are automatic.

Kushler, who is chief technology officer of Swype, estimates that the software can improve even the nimblest text-messager's pace by 20 to 30 percent.Swype charges phone makers a licensing fee for each device sold and is also contemplating for add-ons.

no Ubuntu for tablets

Ubuntu sponsor Mark Shuttleworth has told IT news service Golem that rumours circulating in recent days of a special version of Ubuntu Linux for tablets are based on a misunderstanding. During LinuxTag in Berlin, Shuttleworth told the news service that comments in an interview with Chris Kenyon, Business Development Director at Canonical, have been misinterpreted.
Future Ubuntu versions will continue to be developed for netbooks, desktops and servers. According to Shuttleworth, Ubuntu is working with OEMs on Ubuntu Light, a special netbook version which will be pre-installed on laptops and netbooks and used in parallel with Windows as an instant-on system, but that there was not a special Tablet version of Ubuntu in development.

Official Google Blog: Announcing Google TV: TV meets web. Web meets TV.

Official Google Blog: Announcing Google TV: TV meets web. Web meets TV.: "We’re working together with Sony, Logitech and Intel to put Google TV inside of televisions, Blu-ray players and companion boxes. These devices will go on sale this fall, and will be available at Best Buy stores nationwide. You can sign up here to get updates on Google TV availability."

Google TV: web meets TV

If there’s one entertainment device that people know and love, it’s the television. In fact, 4 billion people across the world watch TV and the average American spends five hours per day in front of one*. Recently, however, an increasing amount of our entertainment experience is coming from our phones and computers. One reason is that these devices have something that the TV lacks: the web. With the web, finding and accessing interesting content is fast and often as easy as a search. But the web still lacks many of the great features and the high-quality viewing experience that the TV offers.

Google TV is a new experience for television that combines the TV that you already know with the freedom and power of the Internet. With Google Chrome built in, you can access all of your favorite websites and easily move between television and the web. This opens up your TV from a few hundred channels to millions of channels of entertainment across TV and the web. Your television is also no longer confined to showing just video. With the entire Internet in your living room, your TV becomes more than a TV — it can be a photo slideshow viewer, a gaming console, a music player and much more.

Google is working together with Sony, Logitech and Intel to put Google TV inside of televisions, Blu-ray players and companion boxes. These devices will go on sale this fall, and will be available at Best Buy stores nationwide. You can sign up hereto get updates on Google TV availability.

some Tips and tricks to maintain a virus free computer

Is your computer infected with virus? Do you often get mysterious error messages? Well this is a common problem faced by almost all the computer users across the globe. There are many viruses and worms out there that could infect your computer. Some of them are harmless, but, they do have the capacity to do any number of nasty things, up to and including, erasing all data from your computer. However there are ways to keep viruses away from your PC. Here are the some tips and precautions to maintain a virus free computer.
  • E-mail is one of the easiest ways by which your computer can catch a virus. So it is always recommended to stay away from SPAM. Open only those emails that has it’s origin from a trusted source such as those which comes from your contact list. If you are using your own private email host (other than gmail, yahoo, hotmail etc.) then it is highly recommended that you use a good anti-spam software. NEVER click on any links in the emails that comes from untrusted sources.
  • USB thumb/pen drives is another common way by which viruses spread rapidly. So it is always a good habit to perform a virus scan before copying any data onto your computer. NEVER double-click the pen drive to open it. Instead right-click on it and select the option “open”. This is a safe way to open a pen drive.
  • Another way is through e-mail client Be careful about using MS Outlook. Outlook is more susceptible to worms than other e-mail programs, unless you have efficient Anti-Virus programs running. Use Pegasus or Thunderbird (by Mozilla),Evolution mail, or a web-based program such as Hotmail or Yahoo (In Firefox).
  • Internet is the main source of all the malicious programs including viruses, worms, trojans and other viruses. In fact Internet contributes to virus infection by up to 80%. So here are the tips for safe surfing habits so that you can ward off virus infection up to the maximum extent.
  1. Don’t click on pop-up windows that announce a sudden disaster in your city or announce that you’ve won an hourly prize. They are the ways to mislead Internet users and you should never trust them. 
  2. You can also use a pop-up blocker to automatically block those pop-ups.
  • Most of us use search engines like Google to find what we are looking for on the web. It is quite obvious for a malicious website to get listed in the search results. So to avoid visiting those untrusted malicious websites, you can download and install the AVG LinkScanner which is a freeware. This tool can become very handy and will help you to stay away from malicious websites.
  • Install a good antivirus software and keep it updated. Also perform full system scan periodically. It is highly recommended that you turn on the automatic update feature. This is the most essential task to protect your PC from virus. If PC security is your first option then it is recommended that you go for a shareware antivirus software over the free ones. Most of the antivirus supports the Auto-Protect feature that provides real time security for your PC. Make sure that this feature is turned on.
  • Install a good Antispyware program, that operates against Internet malware and spyware.
  • Never open any email attachments that come from untrusted sources. If it is a picture, text or sound file (these attachments end in the extensions .txt, .jpeg, .gif, .bmp, .tif, .mp3, .htm, .html, and .avi), you are probably safe, but still do a scan before opening.
  • Do not use disks that other people gave you, even from work. The disk could be infected with a virus. Of course, you can run a virus scan on it first to check it out.
  • Set up your Windows Update to automatically download patches and upgrades. This will allow your computer to automatically download any updates to both the operating system and Internet Explorer. These updates fix security holes in both pieces of software.
  • While you download files from untrusted websites/sources such as torrents, warez etc. make sure that you run a virus scan before executing them.
  • And finally it is recommended not to visit the websites that feature illegal/unwanted stuffs such as cracks, serials, warez etc. since they contribute much in spreading of viruses and other malicious programs.
  •  The major issue is the OS. Most of the computer viruses are created for Microsoft's windows operating systems.You can completely get rid of the menace of viruses by using open-source Operating Systems. These open-source OS use the Linux kernel which is very secure and robust. There are various Linux distributions to cater the needs of the users. Some of them are Ubuntu , Suse, Fedora, Mandriva, etc,.These OS are offered for  free and are immune to viruses. It is recommended that you use these Linux operating systems.

Nokia launches bicycle-powered charger

NOKIA, The world's largest mobile phone maker, launched four low-priced handsets and a recharger that can be connected to a bicycle's dynamo which charges when the wheels turn.The bike kit has a charger, dynamo and a holder to secure the phone to the bicycle.

The bicycle charger kit and handsets, come with a standby battery time of up to six weeks, FM radio and flashlights are aimed at users with limited access to electricity.

The price of the charger kit, which also includes a holder for securing the phone to the bicycle, will vary according to market, but in countries like Kenya,  it would be around 15 euros (18.43 dollars)
The dynamo, a small electrical generator, uses the movement of the wheels to charge the handset through a standard 2 mm charging jack used in most Nokia handsets.

To begin charging, a cyclist needs to travel around six kilometres per hour (four miles per hour), and while charging times will vary depending on battery model, a 10 minute journey at 10 kmh produces around 28 minutes of talk time or 37 hours of standby time, the spokesman said. The faster you ride, the more battery life you generate.
The charger is set to become available through selected retailers and the company's online store before year-end, Nokia said.

create a multi boot CD using script is a shell script designed to build a multiboot CD image containing many different Linux distributions and/or utilities. After creating a multiboot CD you can choose the OS you wish to install at the boot time.

The avantages to making a CD with this script are:
  •  You don't need to burn multiple CDs for small distribution 
  • If you already have the ISO images, it is not necessary to download them again. 
  •  When a new version of one of the distributions is released, you can simply download the new version and run the script again to build a new multiboot image.

   1. Make a folder for building the image. You can give it any name; I call mine multicd.

2. Download the script and save it into that folder. (For version 5.0+, either download multicd[version]- to that folder or untar multicd-[version]-seperate.tar.gz to that folder.)

3. Copy or symlink some of the supported boot images to files in that folder. Note: they must have the names below         (i.e. Puppy must be puppy.iso, etc.) Also, only distros supported by this script will work.

4. Install mkisofs or genisoimage. If your distribution comes with CD/DVD burning sftware, you probably have it already.

5. Open a terminal, go to the multicd folder (made in step 1) and type:

     chmod +x multicd*.sh
     sudo ./multicd*.sh       

      The script will detect which images are present and make a CD for you. They will appear on the menu of the final CD in the order they are listed. (Note: if the final size is over 700 MB, you will have to use a DVD.)

supported linux distributions:

Linux Mint → linuxmint.iso
PCLinuxOS → pclos.iso* PCLinuxOS LXDE → pclx.iso* Knoppix → knoppix.iso (Versions 5 and 6 supported. If you use the DVD version, KNOPPIX2 will be dropped. You can also use the 5.3.1 Japanese Edition if you prefer KDE.)
*the two plugins can both be used for any other version of PCLinuxOS 2009 -customized-
Debian Live → binary.iso
Ultimate Boot CD → ubcd.iso
-not too large-
Slax → slax.iso
Tiny Core Linux → tinycore.iso
Puppy → puppy.iso
Macpup → macpup.iso
Feather → feather.iso
SliTaz → slitaz.iso
Austrumi → al.iso
GeeXboX → gbox.iso
DSL → dsl.iso

First man to be 'infected' by computer virus

A British scientist has laid claim to being the first man to be infected by a computer virus, after he used a contaminated chip implanted in his hand to attack a lab security system.

Dr Mark Gasson,a British scientist, programmed the microchip, similar to those used to "tag" pets, to remotely open his lab's security doors and unlock his mobile phone before having it inserted under his skin.He also infected the implant with a virus, to prove that it could be transferred as the chip and the security system wirelessly exchanged electronic data.

The virus could then have been passed on to other devices interacting with the control system, such as colleagues' swipe cards, in the same way viruses are able to spread across computer networks.

 The results raise the possibility that in the future, increasingly advanced medical devices such as pacemakers, inner ear implants, and other medical devices could become vulnerable to cyber attacks from other human implants.

 Dr Gasson said: "Our research shows that implantable technology has developed to the point where implants are capable of communicating, storing and manipulating data.

"This means that, like mainstream computers, they can be infected by viruses and the technology will need to keep pace with this so that implants, including medical devices, can be safely used in the future.”

He stressed it is not currently thought possible to exploit medical devices such as pacemakers because they have not been analysed for flaws, but said they could theoretically be vulnerable.

He said: "We do not know of any medical device that can be exploited in this way yet but we are very much on the cusp of it being possible.

"It is possible that you could create a virus that completely corrupts the device to the point where it does not work any more."

Implanted technology has become increasingly common in the United States, where medical alert bracelets can be scanned to bring up a patient's medical history.

Dr Gasson said the technology is likely to become more widely used in the future, even for non-medical purposes such as increasing someone's memory.

He said: “Our next evolutionary step may well mean that we all become part machine as we look to enhance ourselves, either because it becomes as much of a social norm as say mobile phones, or because we’ll be disadvantaged if we do not.”

Find invisible users in your Gtalk buddy list

Most instant messaging protocols like yahoo messenger, msn, gtalk, etc,. support invisible users. Anyone can remain online without being noticed by anyone in their buddy list. In this post I'm going to explain how to find the invisible users in your GTalk list. For this i used:
  •    operating system: ubuntu 9.04 
  •    programming language:python language.Install this by running 
            sudo apt-get install python
  •    xmpp module for python can install this by running the following command:   
                         sudo apt-get install python-xmpp
          The interesting thing about GTalk implementation is that it implements user 'invisibility' on the client side, not on  the server side. we can find such invisible-yet-online users by listening to their presence notifications. When ever a user or client joins a sever/network, it sends presence notification for the users. when the user authenticates to the server and becomes invisible, the client sends an 'unavailable' presence to all buddies in the roster. Thus, presence notifications with a presence type of 'unavailable' means that the user is in invisible mode. All Gtalk clients ignore this type of presence; hence, those users are not shown in the buddy list.

using the below python program we can grab the list of invisible users.It uses XMPP module for python. You can install this module in Ubuntu and other debian based distribution by running the following command:
                                      sudo apt-get install python-xmpp

#!/usr/bin/python -W ignore::DeprecationWarning
import xmpp
def presenceHandler (conn, presence):
      if presence:
         if presence.getType() == "unavailable":
          print presence.getFrom().getStripped()
print "Invisible users:"
jid = xmpp.JID(user)
connection = xmpp.Client(server,debug=[])
result = connection.auth(jid.getNode(), password, "client Name")
while connection.Process(1):

Write the above code in a text editor and save it as '' (without quotes)
open the terminal and go to the directory containing the file and type:
         chmod a+x   to get root powers to execute the code.

now type:
This will print the list of invisible users on the command line itself.
