Adding Animations

by David Horachek | March 2014 | Games Open Source

In this article by David Horachek, the author of Creating E-Learning Games with Unity, discusses the various animation systems in Unity3D.

Until this point, we have been successfully developing our game with the in-editor primitives provided by Unity3D. To add a professional layer of polish, we will learn how to add skinned models and various types of animations to our e-learning game. We will download skinned mesh models and animations from a popular site and learn how to integrate them into the game, as we develop a character motion system. We will also learn about the in-editor animation editor and how it can be used to animate static meshes (appropriate for in-game models such as buildings, cars, and statues that are not weighted to a 3D skeletal hierarchy).

In this article, we will discuss the following topics:

  • Exploring 3D hierarchies
  • Skinned meshes in Unity3D
  • Exploring the Mechanim animation system
  • Exploring the Unity Animation editor

Services

by Sébastien Armand | March 2014 | Open Source Web Development

In this article by Sébastien Armand, the author of the book Extending Symfony2 Web Application Framework, has discussed about the basics of services in the Symfony2 framework. A service is an essential and core concept in Symfony2. In fact, most of the framework itself is just a big set of predefined services that are ready to use. As an example, if you just set up a new installation of Symfony2, from your project root, you can type php app/console container:debug to see the full list of services currently defined in your application. As you can see, even before we start writing anything for our application, we already have almost 200 services defined. The php app/console container:debug <service_name> command will provide information about a specific service and will be a useful command to refer to throughout the article.

Target Exploitation

by Lee Allen Tedi Heriyanto | March 2014 | Open Source

This article is written by Tedi Heriyanto and Lee Allen , the authors of Kali Linux – Assuring Security by Penetration Testing. Target exploitation is one area that sets a penetration test apart from a vulnerability assessment. Now that vulnerabilities have been found, you will actually validate and take advantage of these vulnerabilities by exploiting the system in the hope of gaining full control or additional information and visibility into the targeted network and the systems therein. This article will highlight and discuss practices and tools that are used to conduct a real-world exploitation.

Redmine–Permissions and Security

by Alex Bevilacqua | March 2014 | Open Source

Our knowledgebase plugin adds extra content to Redmine projects in the form of categories and articles. These new content areas may contain sensitive information, which we would want to restrict certain users from accessing.

As there are different levels of users in Redmine for issue reporting and management, it is only natural that we would want to restrict access to the content in our knowledgebase plugin in a similar fashion.

In this article, written by Alex Bevilacqua the author of Redmine Plugin Extension and Development, you will be introduced to Redmine's permission system. You will learn how you can take advantage of it to restrict access to content areas within our plugin.

We will cover the following topics in this article:

  • Summarizing Redmine's permissions system
  • Declaring custom permissions
  • Ensuring access restrictions in models, views, and controllers
  • Understanding custom content access control
