Twitter is an awesome tool which increases your site reader but one thing which I don’t like about Twitter is that it has a 140 characters limit. So using this loop-hole of Twitter another site called PageTweet , will help you out to bypass 140 character limit. What it actually does is make you enter your message along with your url and nickname and then gives you a short url for that message. You can actually add the shortened url in your Twitter feed along with some another message.

How is this different from other url shortening services?
After reading the above lines, this would be the first question that generates in your mind. The url shortening services may help you to shorten your url but the url which this site will provides will make your viewers to your targeted site, which now has a PageTweet bar along the top that displays the message that you have typed in PageTweet site. It also shows a mini hit-counter for your shortened URL. Below is the example how this happens.

I am using windows operating system for last decade and also sometime install Linux based distributions for testing purposes, this time I’ve found something really amazing to test operating system on my PC, and this amazing thing is React OS. It is Windows NT based open-source operating system, which supports Windows binary (exe) to run in it.

React OS is still under heavy development and is in alpha stage of development. The developers itself recommend not to use for daily purposes, till some more improvements are made; but if you are a computer geek and love to try out different OS, then you may give it a try. You can download React OS by various means-

• Download React OS as Installation CD, Live CD
• You can also run it virtualized using VMware virtual machine or QMenu
• You can also get the source code of React OS

You can get to downloads page of React OS at here.

Virus-Based Batteries: Tiny, Flexible, Cheap?

By pouring a mixture of the harmless, genetically engineered M13 virus and the metal cobalt over stamped silicon film, Angela Belcher and her colleagues created a flexible, microscopic battery that could be cheaply mass produced.

In theory, it could turn virtually any surface -- from large computers to tiny implanted detectors for cancer or heart disease -- into an energy-storing device.

"The idea of using stamping technique to produce a battery is pretty different," said Belcher. "We can make the batteries really small, which lets us put a power source on all sorts of tiny sensors."

Belcher and her colleagues created the first virus-powered battery in 2006. Since then they have been refining their viral battery while working to create other novel energy-storing devices that could be woven into fabrics or poured into containers.

Their most recent advance, detailed in the Proceedings of the National Academy of Sciences, involves stamping a base material, in this case silicon, so that the negatively charged M13 virus and positively charged cobalt can self-assemble based on their relative charges and the pattern of the stamp.

Stamping the base materials, which can theoretically be nearly any surface, means that the batteries can be produced more cheaply and efficiently. With silicon as the base material, flexible and curved batteries can be created as well.
