Learn how to use a 'do while loop' in your Java programming. 1. Set up an 'int' variable named 'counter' and assign it a '0' value. 2. Set up a standard 'do' loop. Make sure to add a counter, so the loop will end 3. Then write the 'while' condition. Make sure that you set the condition to the same variable name that you used in the counter from step 2. Set the variable to '=' 10 (or any number desired)
Welcome back my friends !! Today we'll go through the second part of this C# series
Math can be tricky, especially when you're trying to decipher algebra. It's a love-hate thing; if you don't love math, then you hate it, and there's no in-between. But it doesn't have to be a pain to solve a few problems. It's actually quite simple once you figure it out. An algebraic equation is an equation that includes one or more variables. These equations can be solved as long as the number of variables does not exceed the number of equations.

This video demonstrates how to solve algebraic equations of the first degree for the variable, "X"; in other words, the variables contained in these equations are not raised to any power other than one, which is implicit. The video starts out with an example of such an algebraic equation. Before beginning to solve the equation, the video explains the meaning of the equals sign, the definition of an equation, and what a variable is. Next the video explains what is meaning by "solving for X". T...
If you want to learn how to program in the Java language, then the first thing you're going to need to do is download and install the JDK. That stands for Java Development Kit, and is the basis for anyone begging in Java, and you need it to get the Javac (Java compiler) running. This video will show you what to do, and will show you how to set a new variable name and value in the Environment Variables under Advanced System Settings on your Windows PC.

This is a helpful video provided by Math Problem Generator. It deals with the complex challenges of dividing variables. The audio is great and provides specific examples of dealing with multiple types of this problem. The video lays out three simple steps. The first being to simplify the coefficient, the second being to divide the variable, and the third being to deal with the results of the division. The information is clearly presented and best of all it's free. I think we all wish there we...
In this Education video tutorial you will learn how to solve a word problem that involves proportions. To solve such problems you got to express the scenario in proportions. For example, in the problem, ‘Jacob ran 10 miles in 80 minutes’; this rate can be expressed as 10miles/ 80 minutes. The second part of the problem is to find out ‘at that rate how far would he run in 2.5 hours’? ‘How far’ being a variable, write it as ‘x’ and this can be expressed as x/ 2.5 hours. So, the complete equatio...
In this free video math lesson YAY MATH, we learn how to simultaneous equations — sets of equations with multiple variables — in basic algebra. With mathematics, as with anything else, not everyone progresses at the same rate. Algebra is no exception. Happily, in the age of Internet video tutorials, this isn't a problem. Those who progress quickly can go beyond what's being taught them and those who are struggling likewise have all the time in the world to catch up. Whether you need help fini...

The video also explains converting percentages to decimals, which is the cornerstone of applying th...
In previous tutorials we have encountered these things called pointers and addresses but we still don't know what they really are. Let's learn a bit more to clear things up.
Welcome back, my amateur hackers! Over the course of the next year, we will be developing our own zero-day exploits. In my first article in this series, I introduced you to buffer overflows, which are the source of some of the most lethal exploits, particularly the "remote code execution," so we are focusing our exploit development here on a buffer overflow.

And, thanks to the Internet, it's easier than ever to follow in their footsteps. For all of the details, watch this installment from Internet pedagogical superstar Salman Khan's series of free math tutorials, we learn how to calculate the variance of differences of random variables.
In this tutorial, we learn how to customize bash prompts with the PS1 variable. The PSI variable will say what something does. You can change this using the export command. Basically, you just type in the same thing and add in something. You can do this by simply typing it in using your keyboard. After this, press enter on your keyboard, then continue to change more things. There are a ton of different things you can do with this. You can find more from the website: http://pastebin.com/f2309f...
In order to simplify complex variables, you must first consider the numerical values separate from the variable. In the case of 24x/48x, you would look at the numbers alone to see if they have any factors. These numbers have the number 6 in common. So, divide it by 6. This will give you 4/8. This still requires some simplification. Two is still a factor for both. So, divide it again by four. This will give you 1/2. Now, if the numerator was raised to the second power, in the original equation...

Encryption is the process of converting you data in to other obscure form so that no one can read it. Encryption can also be done using batch files. Batch files are scripting programs in windows which can be used to program small automatic operations. To do this open a notepad to write the batch program. First turn of the echo by inserting the command '@echo off'. Now write the rest of the program as shown in the video. Now save the image as a bat file. Now you can encrypt this batch file. To...

Learn how to do two step math problems with this video tutorial.
In this tutorial the instructor discusses about the numeric coefficients that we come across while we work with polynomials. He goes on to discuss the numerical coefficient of a monomial stating that it is the number that is present before the variable in the monomial. He states that the numerical coefficient can also be negative or if there is no number present in front of the variable, it indicates that the numerical coefficient is one. This video helps in understanding what the numerical c...

For some odd reason, the Netflix app likes to disable the Nexus Player's built-in screensaver. It doesn't use its own, it simply keeps your screen on indefinitely, which of course can lead to screen burn-in. This is not just an Android TV issue, as the Netflix app does the same thing on Roku and smart TVs.
This video teaches you how to use substitution to find the point on a graph (the x and y coordinates) where two separate equations would cross. Substitution is a trick of algebra that allows you to find this point without making a graph. The first step is to isolate one of the variables (x or y) in one of the equations. That way, you know that that variable is equal to everything on the other side of the equals sign from it. You can then take that whole side, and substitute it into the other ...
In python, or any scripting language for that matter, there are certain things that you will carry with you throughout your entire scripting career. Some of the most basic things that you will keep with you are output, variables, and their value types. We'll start by going over output, then cover variables and their types. So, let's get started!
Format strings are a handy way for programmers to whip up a string from several variables. They are designed to save the programmer time and allow their code to look much cleaner. Unbeknownst to some programmers, format strings can also be used by an attacker to compromise their entire program. In this guide, we are going to look at just how we can use a format string to exploit a running program.
Hey readers! This tutorial will be the entry point for the introduction of buffer overflows. Something like requesting user input is a very common place for vulnerabilities to pop up and we will definitely have fun while trying to make programs crash. But for now, let's start with how we can get input from a user.
Before I start a series on remote exploitation, I think we should learn the basics of Perl. Perl, Ruby, C, C++, Cython and more are languages that some penetration testers just need to learn. Perl is a great language for multiple things, sadly, like many other scripting languages, it is limited by the environment in which it is designed to work in.
