Facts about Bill Gates !!

1. Bill Gates earns $250 every SECOND, that's about $20 million a DAY and $7.8 billion a YEAR!

2. If he drops a thousand dollars, he won't even bother to pick it up
because in the 4 seconds it takes to pick it up, he would have already earned it back.

3. U.S's national debt is about $5.62 trillion. If Bill Gates wants to
pay the debt by himself; he will finish it in less then 10 years.

4. He can donate $15 to everyone on earth and still be left with $5
million for his pocket money.

5. Michael Jordan is the highest paid athlete in the U.S. If he
doesn't drink and eat, and keep his annual income at $30 million,
he'll have to wait for 277 years to become as rich as Bill Gates is
today.

6. If Bill Gates were a country, he will be the 37th richest country on earth.

7. If you change all of Bill Gate's money to $1 bills, you can make a
road from earth to moon 14 times back and forth. But you will have to make that road non-stop for 1400 years, and use a total of 713 BOEING 747 planes to transport all the money.

8. Bill Gates will be 42 this year. If we assume that he still can
live for another 35 years, he has to spend $6.78 million per day to
finish his money before his death.

Samsung to launch two sub-Rs 15,000 smartphones this month !!

 =>Samsung will launch two smartphones in India this month for less than Rs 15,000, intensifying competition in the mid-segment mobile market.

The Korean company, which has a 49% share in India's smart phone segment, will offer options in local languages to attract non-English speaking customers.


=>"We will be launching two new smartphones priced for the mid-segment market. Every phone from Samsung will have nine vernacular language options," Samsung country head (mobile business) Vineet Taneja said, without mentioning the prices.


=>However, a company official said the phones may be priced in the Rs 5,000-15,000 range. Most mobile phones in India are sold in this price range, including Nokia Lumia 520 and 620, Blackberry Curve series, Xolo smartphones and Micromax Canvas 2. The Samsung phones will offer access to content and applications in Hindi, Punjabi, Tamil, Bengali, Telugu, Kannada, Malayalam, Marathi and Gujarati.

Memory Leak !!

Memory leaks occur when the programmer forgets to free up memory after the program no longer needs it. Other times, a programmer may try to access a chunk of memory that has already been freed, leading to dangling pointers that can cause serious bugs or even crashes.

Garbage collection .. !!

1.Garbage collection is the systematic recovery of pooled computer storage that is being used by a program when that program no longer needs the storage. This frees the storage for use by other programs (or processes within a program). It also ensures that a program using increasing amounts of pooled storage does not reach its quota (in which case it may no longer be able to function).



2.Garbage collection is an automatic memory management feature in many modern programming languages, such as Java and languages in the .NET framework. Languages that use garbage collection are often interpreted or run within a virtual machine like theJVM. In each case, the environment that runs the code is also responsible for garbage collection.



3.In older programming languages, such as C and C++, allocating and freeing memory is done manually by the programmer. Memory for any data that can't be stored within a primitive data type, including objects, buffers and strings, is usually reserved on the heap. When the program no longer needs the data, the programmer frees that chunk of data with an API call. Because this process is manually controlled, human error can introduce bugs in the code.

BUBBLE SORT - ALGORITHM !!

Let A be a list of n numbers .Sorting A refers to the operation of rearranging the elements of A so they are in increasing order .i.e .. so that ...

A[1] < A[2] < A[3] <  .....  < A[N]

For example , suppose A is is originally in the list ..

               8,4,19,2,7,13,5,16
After sorting ..
               2,4,5,7,8,13,16,19

BUBBLE(DATA,N)
Here DATA is an array with N elements .This algorithm sorts the elements in DATA.

1.Repeat Steps 2 and 3 for i=1 to N-1.

2.        set PTR = 1 [initialize pass pointer PTR ]

3.        Repeat while PTR <= i - j [Executes pass ]

           (a) If DATA[PTR]>DATA[PTR + 1] ,then

                     Interchange DATA[PTR] and DATA[PTR + 1]

                [End of if structure ]

           (b) Set PTR = PTR + 1

       
            [End of inner loop ]
        
        [End of step 1 outer loop]

HOW CLOUD COMPUTING WORKS .. !!!

Cloud Computing   has been changing how most people use the web and how they store their files. It’s the structure that runs sites like Facebook, Amazon

and Twitter and the core that allows us to take advantage of services like Google Docs and Gmail. But how does it work?

Let’s understand what the term “cloud“ refers to.  The concept of the cloud has been around for a long time in many different incarnations in the business world. It mostly means a grid of computers serving as a service-oriented architecture to deliver software and data.What differentiates the cloud from the way those are set up is that the cloud utilizes the resources from the computers as a collective virtual computer.The cloud takes advantage of that a lot of the software that people use nowadays are completely web-based. For example, if you are hosting your website on a local server or from your PC, you must usually select a particular operating system (Windows/Linux/Mac), to determine what software you can run on that particular server. If your site is being hosted in the cloud, there is no need to do that. You can run Windows and Linux programs side by side.

How is that done?

To understand how does cloud computing work, imagine that the cloud consists of layers — mostly the back-end layers and the front-end or user-end layers. The front-end layers are the ones you see and interact with. When you access your email on Gmail for example, you are using software running on the front-end of a cloud. The same is true when you access your Facebook account. The back-end consists of the hardware and the software architecture that fuels the interface you see on the front end.

Because the computers are set up to work together, the applications can take advantage of all that computing power as if they were running on one particular machine. Cloud computing also allows for a lot of flexibility. 

Will it change the way we use computers?
Sure, most of us still use some version of Microsoft Office or Quickbooks that was installed on our computers, but even those kinds of software are now offering an online version that can be used instead. The possibility of being able to access your data and software wherever you need it makes this transition very appealing to most people.

Facebook introduces shared photo albums !!!

A picture's worth a thousand words, and now Facebook is letting others add to your conversation.
Fear not, for Facebook is finally going to allow you to collaborate with your friends to create the definitive photo album of every social encounter.

Like the system for creating events and inviting other friends to be "administrators," the new shared albums feature will give users a new "add contributors" button on the upper left-hand corner of a photo album after they first create it.
The album's creator will be able to add up to 50 additional contributors, each with the ability to add an additional 200 photos to the album.
Facebook said that the feature is only available on the desktop version of the social network for the time being, and will be rolled out to English users to start with a wider launch follow the initial trial period.

Facebook engineers developed the new feature in order to resolve a common frustration of multiple users creating nearly identical photo albums of the same event — a problem that smaller developers have tried to resolve with varying levels of success (and failure) with apps like Flock, Albumatic, and the notoriously unpopular Color.
 Album creators will have the power to delete or modify photos in the album, but contributors will have editing power over photos that they upload. The feature is not available for Page albums, says a Facebook spokesperson.
