Dry water looks like a powder, but a quick squeeze is enough to make it a fluid.

Well, the reason behind it is that, it soaks carbon three times better than water, and hence will help us fight against the global warming. The dry water looks just like the powdered sugar and each particle of that powder contains a water droplet coated by a sandy silica coating.

At the American Chemical Society in Boston(US), Ben Carter from the university of Liverpool presented his research and said:- “There’s nothing else quite like it”

The other uses of dry water might be expanding energy source potential of dry gas or storing methane. As told by Carter, their team have also used it as a catalyst in to speed up reactions between hydrogen and maleic acid. Which produces succinic acid, which is a key material to make drugs and food ingredients. The use of dry water particles makes the process greener and energy efficient.


Talking about the history of this, it was actually developed back in 1968, but it was forgotten. It was then rediscovered in 2006, for study purpose and a group of scientist at the University of Liverpool to find a use of it.

As said by Carter – “Hopefully, we may see ‘dry water’ making waves in the future.”

The Dry Water” is actually tiny droplets of water coated in modified silica, better know as sand. The constitute more than 90% of powdered water and silica coating prevents them from collapsing and combining as fluid.In laboratory-scale research, the team found that dry water absorbed over three times as much carbon dioxide as ordinary, uncombined water and silica in the same space of time.

As told to the telegraph – Not only that, dry water technology can also apply to other liquids. The Liverpool University team showed that by transforming a simple emulsion – such as an oil and water mix – into dry water, it could provide a safer way to store and transport potentially harmful industrial materials.

This amazing discovery will surely help to fight global warming and has other applications, but it has also made some jokes look stupid. Since when does spilling water not make something wet? How do you get holy water? Boil the hell out of it! And what about hydrophobia …

There are other versions of the same series including the graphics card. But you have to add few extra bucks for that. Overall, this model is best for a budget conscious buyer and it is the best deal among all other laptops of the same range. It is cheap and efficient.. and perfectly meets the requirements of buyer. Be it a student, designer or a professional.

The only two cons of this laptop is its size and a weak but satisfying battery life. But, having a big display unit obviously increases the size and to some extent the battery life also. Besides the cons, it has a very good build, improved performance on graphics and not to forget the full sized keypad.

Now, talking about the pros

• Good build and attractive design
• Very Good performance
• HD support
• Dedicated numpad
• A wide screen which gives you an amazing experience (while watching movies or other videos)

Review :

The Acer Aspire 5740 has 15.6 inch LED-backlit screen with aspect ratio of 16:9 which display multimedia content very well. A 2-megapixel webcam on the top of the screen is perfect for video chats and conferencing. The Dedicated numpad makes the keypad wide but it is good for typing and smooth to type on. Talking about the touchpad, it is big and easy to use and move your fingers on it. There’s a lock-key provided to lock the the touchpad if you want to use any other device such as usb mouse. One dedicated button to launch recently used program.

The only two shortcomings are big size and less battery backup. But if you want to have a wide screen and a long battery life…certainly not possible. You have to compromise with it. But, 3.5-4 hours of battery life is enough. Isn’t it ? If you want to buy other laptops having same features, you have to loose your pocket a bit. Dell, Hcl and Lenovo have got some good models, but will cost you around 40k. So, Acer Aspire 5740 should be your choice, if you are looking for a smart, high performance and cheap notebook. It is best for the forgiving customer. The features and performance are sufficient.

Price: Around Rs. 35,000/=

Have you encountered the pop up window as below ?

If yes … then you must have chosen to password protect your account details saved in firefox. This is a very secured feature. But, what if you forgot the master password ? This becomes more irritating… when everytime you open a website for which you have saved a password in firefox .. and when the master password window pops up… you realize that you do not remember it anymore.. and just choose “Cancel” ! Everytime you do this .. you feel more frustrated.

Although there are methods to recover that master password … and that too by Brute Force, which is hit and trial process.  There is a tool “Firepassword” developed to retrieve the encrypted passwords from the firefox database. It is a console based tool and can be used offline. You need to know all the commands of it before using it. And then export it to a text file.

Coming back to resetting… me too .. forgot the master password and suffered more than a year and never really cared much. But, recently I came to know a trick to reset it and saved me.

Just follow the instructions below and you can get your master password RESET. But before that, please note that this method will neither recover your master password nor retrieve your account details saved in firefox. It just RESETS the master password. In a sense, it is good. Because, if anybody has to reset your password, then he/she can not get your account details saved in it.

So here is the procedure :

1. Open firefox browser.

2. In the address bar, simply copy the address below and paste it.

3. Hit enter.

4. You will be prompted : If you reset your master password, all your stored web and e-mail passwords, form data, personal certificates, and private keys will be forgotten. Are you sure you want to reset your master password ?

5. And in the bottom right, you will see options as below.

6. Choose “Reset”.

And done ! Now you can start fresh. And no more annoying pop up window, you don’t remember password of which.

Stay Tuned !

Bluetooth watches

These two watches are named TM84-0351V and TM84-0352V and they can somewhat control your cell phone via Bluetooth. At the moment these watches are only compatible with Japanese phones . Now let’s take a look at its features. These watches can display mail or news on there own display that you received on your cell phone. Only limitation is that they can show upto 210 character messages. Besides reading mail, you can also store up to 10 mails on your watch and read it at any time. With their LCD display and magnify feature these watches should provide easy reading of mail in full color.


Another option is that these watches will notify you if you receive a call or a mail on your phone with vibration,glowing display and icons . That way you can easily control your cell phones volume,hold or reject calls and check your battery level. With all these features you can even control you camera shutter with a single button. These watches are light and they come in leather or stainless steel but at the moment they only work with certain cell phones from SoftBank mobile operator. As for the price of these devices, it remains unknown.

Reserved for the websites, the IP address book is about to fill completely. It is almost 95% full at this stage. This will eventually require a new Internet protocol version. At present, Internet Protocol Verson 4 (IP v.4) is being used, which uses a 32 bit number system. Millions of combinations have been prepared and alloted worldwide, but the remaining unalloted ones are few… This is also misunderstood as the End of the Internet (as shown in many News Channels previously). But, it is not…

The depletion of the IPv4 allocation pool has been a concern since the Internet started to grow.  IPv4 provided only 4 billion addresses. And the only solution to this exhaustion of IPv4 is to implement a new and better Protocol i.e. IPv6.

Which means, 128-bit based IP v.6 is next to be implemented. It has been declared that by June 2011, the remaining unalloted ip address will be alloted and IP v.6 will be on its way …

IPv6 has a larger address space than IPv4. More combinations, implements new features that will simplify address assigning, network security is integrated and lot more features. We don’t need to get the background details. In a nutshell, this new Internet Protocol will include huge combinations and better security.

John Curren (American Registry for Internet Numbers, ARIN) says that it is a big challenge to make countries worldwide agree to implement IP v.6.
