Character count is a framing technique in which the size of different frames can be unique. The first character of every frame specifies the number of character that follows in the frame. At the destination when the data link layer sees the character count, it knows how many characters follow...

The greatest thing about Python is that it is a COMMUNITY-DRIVEN language and python’s official website python.org have done great work in including new libraries. What community-driven here means is that anyone and everyone can contribute to python libraries. Lets say some Jack wrote a...

Tuples and Dictionary are data structures which prove to be very handy in many cases. Tuples are collection of data elements which may be of different type, while dictionary acts as a map in which every index is mapped to some value. The index and the values may be of any type. How to declare...

Android has a pretty nice lock-screen, and can be customized according to your choice. You may secure your phone using some pattern, pin, password etc. Also you can change the wallpaper that appears on your lock-screen. However, if you are bored with the default android lock-screen, you may very...

When a force parallel to the cross section of an object is applied on it, it is called as stress. The shape of the object changes. In this post, I will show you how to change the figure to this final shape by implementing a code to shear a circle in C++. You can apply the shear operation either...

To run a piece of code or a sub-part of a program only in some specific cases, you need to specify conditions. If-else is the most common kind of structure used to implement conditions. If-else conditions in python can be used to implement multiple branches as shown in the diagram below: In the...

Byte stuffing is another important concept employed in data transmission. In framing, the starting and ending of a frame is marked by a flag character. If the data transmitted contains the frame character byte stuffing needs to be done. An extra byte is stuffed before the flag character present...

Loops are an important programming construct because they make programming that much more easy and convenient. For instance, your program repeats a code fragment hundred times, it would be very bad if you would have to type the same code hundred times. What if the size of the code is hundreds of...

WordPress allows you to create an account on their official website and start your blog hosted on their servers very easily. However, many bloggers including me may prefer to use it on our own servers, on our own domains. I will guide you through how to install WordPress on your own server in...

Bit stuffing is a process employed in data transmission where in non-information bits are inserted into the data being transmitted. It is a method used in framing to differentiate the data from the flag characters. Bit stuffing allows an arbitrary number of bits to be present in a frame. At the...

Some of the basic operations in computer graphics include scaling, shearing and rotation. I have already discussed how to scale a circle. In this post i shall explain the rotation operation and implement a program to rotate a square. A square can be drawn using any of the line drawing algorithms...

User defined functions form an integral part of most programming languages these days. They add modularity to the program. The program becomes much easier to understand, debug and extend. Also, when the same code has to be repeated again and again, it is better to use a function than write many...

Files are important in computers. They help in saving data and retrieving them as and when required. So far whatever we worked was directly in the python terminal, or any other IDE. When you close the IDE, your data is lost. It means that whatever variables you created, or operations you...

In this era, what does not leak? It has become very difficult to keep secrets before the release of any product. The companies may not like the intrusion, however,  the customers love it. The news is informs iPhone 6 leaked feature. A recent YouTube video claims that the display of iPhone 6 has ...

List is an important concept for working in Python. It is similar to arrays in other programming languages like C++, however has more to it. If you have ever used arrays, you must be aware that arrays are named lists of finite number of elements of same data type . Lists may contain elements of ...

In a post on Blackberry’s official blog, Matt Young announced that blackberry is coming up with a new phone which is going to break all stereotypes about phones design and built. On 7th July 2014, in his post, Matt Young unveiled this new design and explained the thought process behind...
