Smallest Computer

Ya its right ,,the World Smallest Computer..

Its just like your normal computer and have a great portability.

Comptek has launched UMPC in India, claimed to be the smallest PC in world with all features of a tablet PC including Wi-Fi, Bluetooth and Web camera inbuilt. Weighing only 529 grams, the Wibrain Bl Ultra Mobile Computer is a small (approximately 7.5"x3.25"), Tablet PC with touch screen, mouse pad, 1.2 GHz processor, 1 GB RAM, 60 GB HDD, integrated stereo speakers, USB and 24 Pin connector for external monitor, battery backup and comes loaded with a version of Ubuntu Linux or Wmdows XP.

Long before there were iPod Nanos and laptops, in fact, long before before Bill Gates was even born, a British mathematician proved that it was possible to build computing machines that could be programmed to carry out any calculation that could ever arise. The mathematician was Alan Turing, and the theoretical device he invented in the 1930s is nowadays called a Turing machine. (There is not just one Turing machine; rather they are an entire class of hypothetical computing devices.

The computer built at Bletchley Park, like all computers since, is much more complicated than Turing's theoretical machine. In principle you could build a physical Turing machine, and in fact several people have done so, but they are not useful; it could take tens or hundreds of years to program them to carry out useful calculations, and for some problems even longer to find the answer. They may be simple, but they are not practical. Their importance is that they help us understand what computation is and how it works. (For instance, the security of your credit card number when you order something online depends crucially on mathematics involving Turing machines.)

The idea of building machines to do arithmetic (in particular) is almost as old as mathematics itself. The earliest attempts, such as piles of pebbles or the abacus, were not really carrying out the mathematical computation, they simply provided a convenient way to store numbers for the human operator who actually did the math. Blaise Pascal (1623 - 1662) was one of the first people to design and build a machine that really did carry out calculations, called the Pascaline. Charles Babbage (1791 - 1871) is another famous name in the history of designing calculating machines. But all of the early attempts focused on designing machines to perform particular calculations or particular kinds of calculations. No one thought of building a machine that could carry out any computation.

Part of the reason is that it was not until the 1930s that anyone had tried to specify precisely exactly what is meant by "a computation." Turing invented his "Turing machine" concept in order to provide a precise definition: a function from numbers to numbers (say) is declared to be "computable" if and only if it can be calculated by some Turing machine.

Reactivate Your Windows XP When You Lost Windows License Key

Generally this problem arises ..

I myself give you the solution just this post and reactivate your Windows XP

In case you have lost the Microsoft Windows CD, you can get back the lost number by utilizing freeware license finder that goes through your system registry files in order to retrieve your original key.

If you have misplaced the Windows serial key or finding it hard to eliminate any hardware error after Windows XP e-installs, then create an alternative of file ‘wpa.dbl’ in Windows 32 folder. ‘wpa.dbl’ is a database file for your system, where you can store XP activation key together with information on hardware arrangement. Whatever changes you make on the system, it will be shown in this file.

Hence, if you wish to retain the old system configuration, you will have to use the support of ‘wpa-dbl’ file and retrieve it after re-installing Windows XP to re-start your system.

This ‘wpa-dbl’ exists in the "c:\Windows\System 32 "

Be careful while following this steps..

IMPORTANT:

First and foremost, you need to shift to the system 32 folder –

C:\Windows\system 32 folder; when Windows XP is already stored in the C drive.

Then look for file ‘wpa.dbl’ and create a support through normal ways like CD burning/ storing it in your floppy disk.

Now you can safely shift it to safe mode [F8] while re-installing the Windows XP.

Copy the previous ‘wpa.dbl’ file and re-store it to the system 32 folder! Now your job is done and Windows re-started is ready for use.

Now make the backup of this "

wpa.db

" so that you can use whenever you want...

This is MaktMin helping you to solve your regular problems about your PC.

TaskManager , Regedit, CMD not working

Ya !
many a time its happen that your Taskmanager is not open
ERROR: Task Manager is disable by your Administrator
ERROR: Regedit is disable by your administrator
Don't worry here I have a simple solution for that ...
This solution doesnot include any big code or procdure
just follow this simple steps ..
>Goto to run and type c:/windows/System32
or
Goto system32 directory within the Windows directory
find taskmgr for taskmanager and find regedit for regedit

and just rename it and have the access on them again...
this is due to because Virus find them with their names and as you rename them they were strangers to Virus
The same way to use the CMD
find the and rename it and have access on it.
if you rename the CMD as abc then call the cmd from run as abc
>Goto run and type abc
your cmd will be open ..
do now whatever you want to do ......

Apple releases iPhone software 3.1.3

Lest you think we’re all-iPad all-the-time here, allow us to bring you news about Apple’s last revolutionary device. On Tuesday, the company released iPhone OS 3.1.3, which includes a few minor improvements, security patches, and bug fixes for the iPhone and iPod touch. The update is available via iTunes when you plug in your device.

Among the embarrassment of riches that iPhone OS 3.1.3 brings is better accuracy for the battery level on the iPhone 3GS, a problem where third-party programs would sometimes not launch, and a bug that could cause an application to crash when using the Japanese Kana keyboard.
There are also a few security patches in the release, such as a CoreAudio fix to guard against maliciously crafted MP4 files, an ImageIO patch that similarly protects against malicious crafted TIFF images, improved handling in certain USB control messages to prevent someone with physical access to the phone from accessing private data using the device's recovery mode, and a pair of patches for WebKit that deal with HTML Mail messages and maliciously crafted FTP servers.

As always, Apple’s use of full disk images for iPhone OS updates means you’ll have to download a big ol’ 291MB file.
