DjVu (pronounced "déjà vu") a set of compression technologies, a file format, and a software platform for the delivery over the Web of digital documents, scanned documents, and high resolution images.
DjVu documents download and display extremely quickly, and look exactly the same on all platforms with no compatibility problems due to fonts, colors, etc. DjVu can be seen as a superior alternative to PDF and PostScript for digital documents, to TIFF (and PDF) for scanned bitonal documents, to JPEG and JPEG2000 for photographs and pictures, and to GIF for large palettized images. DjVu is the only Web format that is practical for distributing high-resolution scanned documents in color. No other format comes close.
Typical DjVu file sizes are as follows:
* bitonal scanned documents: 5 to 30KB per page at 300dpi (3 to 10 times smaller than PDF or TIFF)
* color scanned documents: 30 to 100KB per page at 300dpi (5 to 10 times smaller than JPEG).
* photos: 2 times smaller than JPEG, about the same as JPEG-2000, but the decoder/renderer is progressive and has minimal memory requirements.
* palettized images: 2 times smaller than GIF (up to 10 times if it's mostly text).
* digital (non scanned) documents: between 1 and 3 times smaller than PDF or gzipped PS (depending on the amount of pictures), but rendering, page flipping, zooming, panning are incomparably faster, and the image quality on screen desplays is much better (antialiased text, etc).
More importantly, all DjVu images render very quickly and can be smoothly zoomed and panned. Pages of a document can be turned instantly, with no annoying delay.
DjVu is used by hundreds of academic, commercial, governmental, and non-commercial web sites around the world to distribute scanned documents, digital documents, and high-resolution photos.
A short technical description of DjVu is available here.
Demos, and general information about DjVu can be found at DjVuZone.org, or at LizardTech.com.
DjVu was originally developped at AT&T Labs-Research. In March 2000, AT&T sold DjVu to LizardTech Inc. who now distributes Windows/CE/Mac plug-ins, and commercial encoders.
DjVuLibre is an open source implementation of DjVu. See the credits/history page for more details.

Facebook Or Spambook !!!???
people are using the popularity of Facebook to create spam messages
recently there are two new kinds of spam that are very popular
one is that of the to see who visited your profile and other of YouTube video
people should understand that we cannot check who visited our profiles
if it was so in demand Facebook itself would have added it to its features
so before clicking Allow them to use your resources just wait for a minute and rethink
ask your friend who has shared that link whether it is genuine or fake always think what is the need of this application and is it worth it to give away my information...
just to let you know what happens when your click on the Allow button

just to let you know what happens when your click on the Allow button
when you click Allow button you enable the application to read all your information...now you will say whats bad in that but now think of it...your information always lead to your password...this is a part of social engineering...this mostly leads to hacking...
there were reports that many thousands of user information was leaked from Facebook due to the same reason...people just blindly allow there private information to be shared...this is totally wrong
as a end note i would not suggest to completely abandon application but to use it wisely don't fall for cheap tricks and try validating the links before you click on them
BallDroppings - Just Awesome !!
BallDroppings is an addicting and noisy play-toy. It can also be seen as an emergence game. Alternatively this software can be taken seriously as an audio-visual performance instrument. Balls fall from the top of the screen and bounce off the lines you are drawing with the mouse. The balls make a percussive and melodic sound, whose pitch depends on how fast the ball is moving when it hits the line. This delightful application allows experimentation with sound and vision which will compound and intrigue you. Whether you are an adult or child, scientific brainbox or avid gamer. It doesn't have a plot, no heroine, no villain. It has no guns or alien beings. It is simply time to get creative, and those who are creative will love this.

Particle Playground - This is real Programming...
Use your mouse to interact with the particles on the screen!
BE BOLD. Try some crazy stuff. There is much more there than what you might see at first glance.
Hit Spacebar to take a screenshot (then right-click to save)
There's much more to come, this app being a (non-sensical) physics "simulation" there are tons of fun variables to play with, and a lot of functionality "//commented out". I will soon add a simple gui so that the user can play with the gui themselves!
Technology:
Pure Javascript :D

"Everything that goes up must come down. But there comes a time when not everything that's down can come up."
George Burns couldn't probably imagine that his quote would eventually also be applied Google's main page.
Play with the elements and try searching whenever you get tired of it.

Rainmeter - desktop customization platform
Rainmeter is an incredibly customizable performance meter for your PC's desktop.
Once a relatively complicated application, Rainmeter developers have increasingly striven to make the meter's interface more user friendly. This trend started with the 1.0 release and continues now that 2.0 is available. In fact, Rainmeter can do some pretty cool things to your windows desktop, and it's easier than ever now to apply new settings.
Rainmeter now comes pre-installed with a theme called "Enigma", which is a great example of how cool your desktop can look. You can add clocks, calendars, and RSS, as well as a whole range of system monitors. And that's just the beginning. Virtually everything on Rainmeter is customizable, and there are scores of other themes you can download for free to give your desktop a really personal feel.
Enigma has been included specifically because it makes your desktop into a really functional space. You can move different meter windows around on a whim, edit their skins relatively easily, tweak the transparency, and even make them disappear completely. As a way of freshening your desktop, Rainmeter is absolutely fantastic.
While Rainmeter has improved its user friendliness substantially, beginners can still easily get lost in the configuration options and settings. There's really not much reason to mess around with them at all though, unless you want to create your own look. Adding new skins is now much easier and doesn't require coding, although if you want a challenge the option to personalize with your own code is still available.
Rainmeter shows how easy it is to personalize Windows and quite effortlessly revolutionize its looks.
Pros
Pre-installed with stylish Enigma skin
Usability greatly improved
Adds great widgets to your desktop
Cons
Still room for simplification!

Madotate - 3D Desktop for Windows
If you find your desktop gets overwhelmed by too many open windows there are a number of solutions, from the extravagent like investing in a second monitor, to applications that try to give you an expanded workspace, like the spaces feature of Apple's OSX Leopard.
Madotate is a free English language version of a Japanese developed tool that adds a fourth button to the top right of your windows. Alongside close, full-screen and minimize appears a 3D button. Clicking it will transform your window into a tabbed 3D image, which takes up much less room.
The app was designed for Windows 2000/WP, but also seems to run fine in Vista. The only problem we found was with Adobe Air programs - they don't crash or slow down, but don't transform properly. This was developed before Adobe Air, and unfortunately hasn't been updated since. The 3D effect is quite cool, but if you've played with Deskspace it seems pretty basic in comparison, although Madotate has the advantage of being free.
Matodate is a resource friendly way to add a space saving 3D effect to your windows.
Pros
- Doesn't require a lot of resources
- Can improve space management
- Cool 3D effect
