THE NSA
Most of u might not ‘ve heard about THE NATIONAL SECURITY AGENCY..i wont belive if u say u are not amazed after reading this post.
Located in the USA,this is a secret agency working for them.wats this gotta do anything with this blog??it does.this is cryptologic intelligence agency started under the presdidency of HARRY S .TRUMAN.They have a ming boggling collection of listening posts,sattelites,spies and wiretaps around the globe.Thousands of communications are intercepted everyday and they all are decrypted in the NSA.The CIA and FBI depend on the NSA’s intelligence to make their decisions.
DATA ENCRYPTION, as u might know was used even in the period of julius caesar.Caesar was the first code-writer in history. He designed the “perfect square cipher box”.Later the NAZI’s built a encryption machine called ENIGMA during world war 2.Only by having another enigma machine the reciever can break the encrypted information.
Now,in an E-mail the only way to unscramble the encrypted message is to enter the use senders PASS KEY(series of characters,much like a PIN number).Pass keys got bigger and bigger by the day,so it was very difficult to break the code.but THE NSA can break or decipher any kind of codes in a blink of an eye!.Their use of technology is unimaginable.They have a Databank-fortknox of U.S. intelligence data.Millions of HIGHLY CLASSIFIED info around the globe is stored in it.
The US faces many kind of threats.nuclear attack is not the only threat.It is believed dat in the recent past an antigovernment organization placed 27 non explosive flux pods around the New York stock exchange building.These devices when detonated creates powerful blast of magnetism.the simultaneous detonation would create so powerful magnetic field so dat the magnetic media inside the Stock exchange building would go nuts.meaning-computer hard disks,storage banks,floppy disks,tape backups everything woukd br erased permanently.But these devices were interconnected using telephone wire lines for pin point detonation.The NSA intercepted these pulses and stopped them before three hours of the blow off.but im not sure if this incident is for true.It might be
And.If u are an hacker and if u ve hacked any Highly classified info.The NSA ll hire you the first thing.yes,They have the best HACKERS in the world…..

Constructers:
A constructor is a member function with the same name as its class. For example:
class X {
public:
X(); // constructor for class X
};
Constructors are used to create, and can initialize, objects of their class type.
You cannot declare a constructor as virtual or static, nor can you declare a constructor as const, volatile, or const volatile.
You do not specify a return type for a constructor. A return statement in the body of a constructor cannot have a return value.
What is the use of Constructor?
The main use of constructors is to initialize objects. The function of initialization is automatically carried out by the use of a special member function called a constructor.
General Syntax of Constructor
Constructor is a special member function that takes the same name as the class name.
The syntax generally is as given below:
{ arguments};
The default constructor for a class X has the form
X::X()
In the above example the arguments is optional.
The constructor is automatically named when an object is created. A constructor is named whenever an object is defined or dynamically allocated using the "new" operator.
There are several forms in which a constructor can take its shape namely:
Default Constructor:
This constructor has no arguments in it. Default Constructor is also called as no argument constructor.
For example:
class Exforsys
{
private:
int a,b;
public:
Exforsys();
...
};
Exforsys :: Exforsys()
{
a=0;
b=0;
}
Copy constructor:
This constructor takes one argument. Also called one argument constructor. The main use of copy constructor is to initialize the objects while in creation, also used to copy an object. The copy constructor allows the programmer to create a new object from an existing one by initialization.
For example to invoke a copy constructor the programmer writes:
Exforsys e3(e2);
or
Exforsys e3=e2;
Both the above formats can be sued to invoke a copy constructor.
For Example:
#include
class Exforsys()
{
private:
int a;
public:
Exforsys()
{ }
Exforsys(int w)
{
a=w;
}
Exforsys(Exforsys& e)
{
a=e.a;
cout<<” Example of Copy Constructor”;
}
void result()
{
cout<< a;
}
};
void main()
{
Exforsys e1(50);
Exforsys e3(e1);
cout<< “\ne3=”;e3.result();
}
In the above the copy constructor takes one argument an object of type Exforsys which is passed by reference. The output of the above program is
Example of Copy Constructor
e3=50
Some important points about constructors:
* A constructor takes the same name as the class name.
* The programmer cannot declare a constructor as virtual or static, nor can the programmer declare a constructor as const, volatile, or const volatile.
* No return type is specified for a constructor.
* The constructor must be defined in the public. The constructor must be a public member.
* Overloading of constructors is possible.

Google betters image search
Google recently revamped its image search engine to make finding the images you're looking for quicker and easier than ever. The redesigned interface lets you scroll through 1,000 images at once (with larger image previews), and eliminates text on the image search results so you can just focus on the visuals.
Previously when you did an image search, you'd see multiple pages of thumbnails with text showing the file name, dimensions, and a description associated with the image. Now you'll only see a mosaic of tightly packed image results with larger thumbnails and no text. Hovering over an image result will blow up the image, reveal the hidden metadata (for some images), and show a link to search for similar images.
Although you're viewing far more images on one page, it's actually easier and faster to look through them all because of Google's "Instant scrolling" function. Scrolling through a full set of results didn't stall or slow down my pages as the images loaded. You'll still see small page numbers to the left of the results interface to help you keep track of where you are. Google's also transitioning to image ads rather than strictly text ads. You'll find them at the top of the page.
When you click on an image result, instead of viewing the originating Web page with a frame at the top, you'll see a blown up image in the forefront of the screen with the Web page dimmed in the background. To the right of the page you'll see the URL of the Web page and a link to the full-sized image. In addition to the images dimensions next to the link for the full-sized image is text telling you how much bigger the full-size image is than blown up image shown on the page.
Clicking the "X" on the blown up image will take you directly to the originating Web page. I like this layout better than the framed page used by the older Google images format, because you get a much better idea for the size of the image (plus, you may not want to click on the full-image link). It would also be nice if clicking the image would take you to the image's position on the originating page—neither the old or new versions of Google Image Search has this ability.
Google managed to display more and larger image results without slowing load times, and made it faster to find images for which you're searching. The redesign is being slowly rolled out to all users by the end of the week, and currently only works on PCs running Chrome, Safari, Firefox 3.0 (and up), and Internet Explorer 7 and 8.

Who will be Facebook's next 500 million?
Facebook isn't letting its milestone of 500 million active users around the world go unnoticed, with a big "Facebook Stories" user testimony promotion rolling out and normally press-shy CEO Mark Zuckerberg making a Wednesday evening appearance on the ABC World News broadcast in the form of an interview with anchor Diane Sawyer.
There will likely be a lot of talk about Facebook's roots as a wildfire phenomenon among college students in elite U.S. universities and how, thanks to its incremental spread through schools and offices and communities, there are now half a billion people flitting around on its iconic blue-and-white pages. But, looking to the future: who will the next half billion Facebook users be?
"We should expect that mainstream adoption of Facebook users in countries outside of the North America will continue to grow," Altimeter Group analyst Jeremiah Owyang told CNET. "Facebook even threatens domination in niche countries where social networks at a regional level are present."
That's been one of Facebook's biggest growth obstacles overseas: the fact that while it was spreading in the U.S., other social networks were growing fast in other countries. None of them has gotten anywhere close to Facebook's global power, but subtle cultural discrepancies and loyal user bases have meant that it hasn't been easy for Facebook to convince its user bases to make the switch. In many countries overseas, Facebook didn't start to catch on until it was available in the native language, and Facebook's translations rolled out relatively slowly. These started about two and a half years ago with a handful of European languages.
"Penetration (of Facebook into regional Internet markets) is highest in North America, at 69 percent, and Middle East-Africa, at 67 percent, and still pretty high in Latin America (58 percent) and Europe (57 percent)," explained Andrew Lipsman, senior director of industry analysis at traffic firm ComScore. "But there is still a lot of room for growth in Asia-Pacific, which currently has just 17 percent market penetration."
In Facebook's original U.S. market, reports have started to indicate that growth may be plateauing, particularly among young adults. But there are some surprisingly big, well-connected countries where Facebook still has a lot of work to do. Take a country like Germany, where Facebook has only 39 percent market penetration. A regional social network called StudiVZ has proven a formidable rival to Facebook, and German authorities' relative hostility toward Facebook's very U.S.-grown privacy policies may make things tougher. Then there's Brazil, where ComScore charts Facebook's market penetration at just over 22 percent; the Google-owned social network Orkut never caught on in the U.S., but Brazilians love it, and still haven't been completely sold on Facebook as a result.
Some of the countries that ComScore has flagged as potential areas for growth--possibly in tune with strategic efforts on Facebook's part--are Japan, with a 7 percent market penetration; Russia, with 6 percent; and South Korea, with 8 percent. There's also China, where government censors have cracked down on access to Facebook along with other social-networking sites.
We're starting to see some of the growth strategies in place already. Earlier this month, Facebook inked a deal with MOL Global, the Malaysian e-commerce company that owns would-be social-net rival Friendster, to make its Credits virtual currency more accessible in some Southeast Asian countries.
"There is definitely a path to a billion users for Facebook, but how long it takes will depend a great deal on its strategy to spur adoption in some of the larger, low-penetration markets," Lipsman told CNET. "Making a push in India right now is an example of going after what is still relatively low-hanging fruit as a large and growing market with room for continued penetration that does not have significant cultural barrier to adoption."

THE GOOGLE
U guys “google” daily,don’t u?? many times u might ve wondered who owns it?who invented it and many many more questions!i thought that may be i can elaborate on it…
Most of u might not have a clue about how google was created. SERGEY BRIN and LARRY PAGE.They are the proud owners of the google.They invented the google.It first incorporated as a privately held company on september 4 ,1998.By the summer of 2005, each of the founders had a net worth of $10 billion!whoa!that is huge money!it was estimated at that time that the shares held by google was worth $80 million!in SEVEN years they achieved this. so how it all started??The youthful pair of sergey brin and larry page had changed the lives of millions of people by giving them free, instant access to information about any subject. And by being devilishly clever in the Internet age, they had created the best-known new brand in the world without advertising to promote the name. they met in stanford university in the days where second generation computers were famous.they were very good friends and two of the brightest of minds Stanford university has ever produced.they created a small search engine which was used within the stanford campus.They named it GOOGLE(this was a misspelled word of GOOGOL which is a large number ie. 1 followed by 100 zeroes).later in 1998 it became a company.they now own the largest system on earth and are still growing…for more info on this download the book THE GOOGLE STORY by DAVID A.VISE.hope this post was useful.thank you:)

Classes and Objects in C++:
classes:
* A Class is a user defined datatype which contains the variables, properties and methods in it. ‘A class defines’ the abstract characteristics of a thing (object), including its characteristics (its attributes, fields & properties) and the thing’s behaviors (the things it can do, or methods, operations or features). One might say that a class is a blueprint or factory that describes the nature of something.
* Classes provide modularity and structure in an object-oriented computer program.
* The code for a class should be relatively self-contained (generally using encapsulation).
* Collectively, the properties and methods defined by a class are called members.
* For example, the class Dog would consist of traits shared by all dogs, such as breed and fur color (characteristics), and the ability to bark and sit (behaviors).
Objects:
* They are basic run-time entities(An entity is something that has a distinct, separate existence, though it need not be a material existence.) in an object-oriented system.
* Programming problem is analyzed in terms of objects and the nature of communication between them.
* objects communicate with each other by sending messages. They can interact without having to know details of each other’s data or code.
* Messages:The process by which an object sends data to another object or asks the other object to invoke a method.
Hope it was useful to all of u, trying hard to understand the building blocks of OOPS….!!
