Developing GUI apps in python is really cool. I ask those who understand the language to help convert some of the command-line or console programs or apps ( I mean programs that are useful to a hacker ) to GUI. I know GUI makes us lazy and not wanna learn but we should all know its fast. Today's tutorial is on p2p chat app I developed last week and decided to share it with the community since its kinda cool.
What Is IPython? IPython is a richly featured replacement for the standard python interpreter. It offers a wider range of functionality, that the standard

This video is a tutorial on using the Conditional Formatting function of Excel to automatically color alternating rows, which helps your eye to follow across the row. This can be done manually with the “Fill Color” button, but if you add or delete rows after applying the shading, the whole purpose is defeated.
In this video the instructor teaches about inverse functions. Normally in inverse functions problems you are given a function that has a set of points and you are asked to find the inverse of that function. So if the function has a point in the form (x, y) then the inverse function has its points in the form of (y, x). Now when you are given a function f(x) that is in the form of x and asked to find its inverse, equate the function to y. Solve the equation to get the value of variable x in th...
In this video the instructor shows how to graph a piecewise defined function. A piecewise defined function is a function that is defined in separate pieces. In these kind of functions, for different ranges of the value of x, you are given different small functions, all of which together make the whole function. This means your equation of the function is given in the form of smaller functions. Now to graph these kind of equations all you have to do is graph the individual equations in the sam...

To find each of the critical points requested the teacher uses the...
When you need to type in all caps on a computer, you just press the "caps lock" key. But no such key seems to exist on iOS. The "shift" key appears to work at first but will deactivate once you type one capital letter. Holding down the shift key while you type gets the job done, but it's a pain. While it might not be obvious, enabling caps lock is actually really simple.

In this video, we learn how to play Jazz guitar: Functioning & Static Dominant Chords. When you play an A7 going to a D chord, you are playing a functioning dominant, because a five chord always wants to go to a one chord. This is because of the tension in the five chord and how it resolves to the one chord. You will hear that the chord wants to go to a different chord, so make sure you understand this concept as you are playing. If the chord does go to the other, it's referred to as a functi...

Exponential functions are functions which contains terms which are integers raised to the power of variables. Note that the variables are not raised to the power of integers, but the integers are raised to the power of variables. Variables raised to the power of integers are called as polynomials and are a different class of functions. But exponential functions grow very fast than polynomials with the increase in the value of the variable. To understand the growth of these functions take a si...

This video teaches us to draw the graph of a piecewise function. This is shown using two examples. In the first example we have 'y' equal to 'x + 2' for x less than zero and '1 - x' for x greater than equal to zero. We plot two points on the function for x less than zero and do the same for the function with x greater than equal to zero. The graph for the first function is erased for x greater than equal to zero, and the same is done for the second function for x less than zero. Note that the...
This video shows the method to plot the graph of the absolute value of a function. The video shows the example of the function of cube root of 'x'. The demonstrator first plots the graph of a cube root function. This is done by taking the reference point of positive one and positive eight. The graph is drawn for both negative and positive values of 'x'. After this the graph of absolute function is drawn by taking the absolute value of the cube root function. The resultant graph comes out to b...
