Understanding the DotNetNuke Core Architecture

by Michael Washington | April 2010 | Web Development

In this article series by Ian Lackey and Michael Washington, we will be exploring the core functionality of the DotNetNuke architecture. We will be using the Source Code version of DotNetNuke 5.2.2 that can be downloaded from the DotNetNuke CodePlex site. We will start with an overview of the architecture, touching on key concepts employed by DotNetNuke. After this, we will examine some of the major sections that make up the framework. Finally, after we learn about the objects that make up the core, we will follow a request for a page through this process to find out how each page is dynamically created.

Understanding the Python regex engine

by Félix López Víctor Romero | February 2014 | Open Source

In this article by Félix López and Víctor Romero, the author of Mastering Python Regular Expressions, we are going to learn about backtracking using Python. The Python’s Re module uses a backtracking regular expression engine. Although in the very well known book “Mastering regular expressions” by Jeffrey E.F. Friedl is classified as Nondeterministic finite automata (NFA) type, according to Tim Peters https://mail.python.org/pipermail/tutor/2006-January/044335.html is not NFA purely.

Understanding the True Security Posture of the Network Environment being Tested

by Lee Allen | May 2012 | Open Source

There is a good possibility that your potential clients will not understand the benefits of performing a full penetration test. Simply enumerating the known vulnerabilities in a network environment is not suffcient to truly understand the effectiveness of the corporation's combined security controls; we need to prove that the vulnerabilities found have a potential to impact the bottom line. After all, this is what your clients need to know and understand about their environment.

In this article by Lee Allen, author of the book Advanced Penetration Testing for Highly-Secured Environments: The Ultimate Security Guide, we will review some interesting techniques and methods that will let us understand the true security posture of the network environment we are testing.Items of interest discussed in this article include the following:

  • Transferring files to and from the victim machine
  • Password cracking with John the Ripper
  • Brute forcing with THC Hydra
  • Metasploit—learn it and love it

Unity 3.x Scripting-Character Controller versus Rigidbody

by Devon Kraczla Volodymyr Gerasimov | June 2012 | Open Source

Character controller is extremely important part of any game. Essentially, it allows us to interact with it, control our alter-ego, shoot, explore, and do all kinds of crazy stuff. Most common character controller is humanoid, in general it needs to know how to walk, run, jump, attack, it needs to camera rig that will be accompanying it throughout play. All these actions need to be supported on a programming level and we will look into a way that it can be done in Unity. This article by Volodymyr Gerasimov and Devon Kraczla, the authors of the Unity 3.x Scripting, will help you to:

  • Learn Character Controller versus Rigidbody – pros and cons
  • Teach player-controlled character walk, run, jump, and shoot
  • Program camera controls and switching between different camera types with a press of a single button
  • Learn script animations to follow character's actions

Unity 3: Building a Rocket Launcher

by Jate Wittayabundit | September 2011 | Web Graphics & Video

Only Unity fits the bill of being a game engine that allows you to create a full 3D game for free, and with phenomenal community support.

In this article by Jate Wittayabundit, author of Unity 3 Game Development Hotshot, we will learn how to create a rocket launcher. Here, we will first use the FPS camera and controller from the Unity built-in FPS package, but we will tweak our camera view to see from the character's shoulder as in Resident Evil 4 or 5. Then, we will adapt the built-in FPS controller script to be able to play the animation of the character, and make the controller similar to the Resident Evil style controller. Next, we will create a rocket prefab and the rocket launcher script to fire our rocket, which will also include the use of the built-in fire explosion particle and custom smoke particle effect from the launcher when we fire.

Unity 3D Game Development: Don't Be a Clock Blocker

by Ryan Henson Creighton | September 2010 | Beginner's Guides Web Graphics & Video

One cheap, effective way of amping up the game experience is to add a clock. Games have used clocks to make us nervous for time immemorial, and it's hard to find a video game in existence that doesn't include some sort of time pressure—from the increasing speed of falling Tetris pieces, to the countdown clock in every Super Mario Bros. level, to the egg timers packaged with many popular board games like Boggle, Taboo, and Scattergories.

This article by Ryan Henson Creighton, author of Unity 3D Game Development by Example Beginner's Guide, shows you how to build three different game clocks: a number-based clock, a depleting bar clock, and a cool pie wedge clock, all of which use the same underlying code. You can then reuse the code in a game of your own.

Unity Game Development: Interactions (Part 1)

by Will Goldstone | October 2009 |

Games are all about interacting with a virtual world, so where would our character be without some in-game actions? In this two-part article by Will Goldstone, we'll be looking at interactions and dive into two of the most crucial elements of game development, namely, Collision Detection and Ray Casting. In the first part, we will learn how to add an outpost model to our project and learn how to position, scale, assign colliders to objects as well as tag objects.

Unity Game Development: Interactions (Part 2)

by Will Goldstone | October 2009 |

In the previous part of the article by Will Goldstone, we saw how to add an outpost model to our project and also learned how to position, scale, assign colliders to objects as well as tag objects. In this part, we will look at the two differing approaches for triggering the animation giving you an overview of the two techniques that will both become useful in many other game development situations. In the first approach, we'll use collision detection—a crucial concept to get to grips with as you begin to work on games in Unity. In the second approach, we'll implement a simple ray cast forward from the player.
