How to install Java JDK (Java Development Kit) Go to the Oracle Java SE Download Page and click "Download".
Welcome back, NB community, to my series on sorting. I introduced in my last article the concept of complexity. When I say complexity, I'm talking about time complexity.
Welcome back to another tutorial on functions. Last time, we looked inside memory to see what functions looked like in the flesh and all that Assembly was pretty nasty. At least you have some exposure to it. This time, we will be examining how functions work with the stack.
Before I continue with a topic on strings, we first require some fundamental understanding of how memory works, i.e. what it is, how data looks in memory, etc. as this is crucial when we are analyzing vulnerabilities and exploitation. I highly suggest that your mind is clear and focused when reading the following article because it may prove to be confusing. Also, if you do not understand something, please verify all of your doubts, otherwise you may not completely understand when we touch on...
Hey there, reader! In this tutorial we are going to explain how values are stored in variables as either signed or unsigned. Try to not get lost!
Why did I write this when they're tons of scanning tools available.
As you might know, there are a multitude of tools used to discover internal IP addresses. Many of these tools use ARP, address resolution protocol, in order to find live internal hosts. If we could write a script using this protocol, we would be able to scan for hosts on a given network. This is where scapy and python come in, scapy has modules we can import into python, enabling us to construct some tools of our own, which is exactly what we'll be doing here.
Welcome back, my budding hackers! I began this series on Linux basics because several of you have expressed befuddlement at working with BackTrack on Linux. As a hacker, there is no substitute for Linux skills.

Watch this instructional cello playing video to learn how to create a sound on the cello. The sound production is composed of the various elements used to create the sound on the cello. There are three variables that determine the kind of sound produced: how much weight will you put into the string, the speed of the bow, where you put the bow. This tutorial is great for beginning cello players.
Watch this video to learn how to create OOP design with C++. This video also covers public and private variables and functions.
Watch this video to learn how to use void functions with C++. The video also covers the use of more than one return statement, immediate return, and variable scope/visibility.
Today's word is "capricious". This is an adjective which means variable or erratic.
This demonstrates how to wire a 555 timer chip for Pulse Width Modulation. Items used: solderless breadboard, 555 chip, 510 ohm resistor, 100k ohm variable resistor, 1 RGB LED at 20-25ma, wires, and 9v battery. And those vertical lines are what i mean in terms of what you can see only on the camera. You can see the led light of course without the camera.
YouTube Hack! Youtube now uses a new gdata format and doesn't require a developer key. It also added a whole bunch more variables you can attach to the query string making things possible that weren't before.

In this tutorial I will be explaining the purpose of unique encryption/decryption scripts ( I will be referring to these at "UEDS" for this tutorial). Then, I will show you how to make one. Finally I will talk about the downsides to the method I use. I will also provide links explaining the concepts and algorithms used in encryption to anyone who wants to see what is going on under the hood.
Developers creating login systems know better than to store passwords in plain text, usually storing hashes of a password to prevent storing the credentials in a way a hacker could steal. Due to the way hashes work, not all are created equal. Some are more vulnerable than others, and a little Python could be used to brute-force any weak hashes to get the passwords they were created from.
When the climate changes, so do all the things that rely on the climate, including people, plants, and pathogens. A European study recently took a broad look at what kind of microorganisms are most likely to be affected as climate change heats, cools, dries, and wets the world around us.

Welcome back! In the last iteration of how to train your python, we covered error detection and handling. Today we'll be diverging from this and discussing functions. More specifically, we'll be creating our own functions. First we'll need to understand exactly what a function is, then we'll get on to making our own! So, let's get started!
