Packt Open Source books

Packt Open Source books will continue to be built around the “community experience distilled” motto, focussing on taking real advice from the community around projects, and refining and distilling it into easy to follow specialist information.

 

Through this, the Open Source Royalty Scheme will continue to support open source projects, offering a royalty for the sale of each book to the project on which that book was written.

Open Source Awards

The Open Source Awards is an annual online event held by Packt Publishing to distinguish excellence among Open Source projects. We aim to play our part in the growth of Open Source software and see the annual Award as the ultimate platform for not only appreciating the great things projects have given back to the community but also supporting projects who have future potential to change things for the better.

Open Source Project Royalty Scheme

Packt believes in open source and helping to sustain and support its unique projects and communities. Therefore, when we sell a book written on an open source project, we pay a royalty directly to that project. As a result of purchasing one of our Open Source books, Packt will have given some of the money received to the Open Source project.

In the long term, we see ourselves and yourselves, as customers and readers of our books, as part of the Open Source ecosystem, providing sustainable revenue for the projects we publish on. Our aim at Packt is to establish publishing royalties as an essential part of the service and support business model that sustains open source.

The Software Task Management Tool - Rake

by Andrey Koleshko | April 2014 | Open Source

In this article, by Andrey Koleshko, author of the book Rake Task Management Essentials, we will cover the installation of Rake, the definition of basic terms such as rake task and Rakefile, and how to use them for easy programming issues. The introduction will be given using straightforward examples to explain the terms as clearly as possible. You will see that Rake is a tool that is written in the Ruby programming language, and that's why any Ruby code can be written in a Rake application. Also, you have the choice of using any available Ruby library in a Rake project. This feature makes Rake the winner compared to many other build tools, which use their own limited languages. The article will serve as a base for introducing Rake's Domain Specific Language (DSL) and project file structuring.

In this article, we will cover the following topics:

  • Installing Rake
  • Introducing rake tasks
  • The command-line arguments
  • Using global Rakefiles to run tasks anywhere
  • Defining custom rake tasks
  • The structure of a Rake project
  • The code conventions of Rake

In order to make our entity work properly in a multiplayer environment, certain changes need to be made to our script.
