Automating Your System Administration and Deployment Tasks Over SSH

by Dr. M. O. Faruque Sarker | March 2014 | Cookbooks Networking & Telephony

In this article, by Dr. M. O. Faruque Sarker, author of Python Network Programming Cookbook, we will cover the following recipes:

  • Executing a remote shell command using telnet
  • Copying a file to a remote machine by SFTP
  • Printing a remote machine's CPU information
  • Installing a Python package remotely
  • Running a MySQL command remotely

This article promotes some interesting Python libraries. The recipes are presented aiming at the system administrators and advanced Python programmers who like to write code that connects to remote systems and executes commands. The article begins with lightweight recipes with a built-in Python library, telnetlib. It then brings Paramiko, a well-known remote access library. Finally, the powerful remote system administration library, fabric, is presented. The fabric library is loved by developers who regularly script for automatic deployments, for example, deploying web applications or building custom application binaries.

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.
