Packt Open Source
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.
Believe in Open Source
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.

Using Debug Perspective – setting breakpoints
by
Anatoly Spektor | May 2013 | Java Open Source
The article, Using Debug Perspective, will guide you through the ways of setting up breakpoints and navigate through the code using various breakpoint manipulation options. This article by Anatoly Spektor, author of Instant Eclipse Application Testing How-to, will guide you to learn what breakpoints are and how to use them. After reading this article, you will be able to effectively debug Java applications of any scope. Fortunately, any prior knowledge of Eclipse is not required; thus it is suitable for developers with any level of experience in Eclipse application development and testing.

by
John Torjo | May 2013 | Open Source
In this article by John Torjo, author of Boost.Asio C++ Network Programming, we'll implement a small client/server application, which is probably the easiest client/server application you will ever write. This is the Echo application, a server that echoes back anything a client writes, and then closes the client's connection. The server can handle any number of clients. As each client connects, it sends a message. The server receives the full message and sends it back. After that, it closes the connection.
Therefore, each Echo client connects to the server, sends a message, and reads what the server replies, making sure it's the same message it sent and finishes talking to the server.

by
Fernando Monteiro | May 2013 | Open Source
Another alternative much discussed by the community of developers is transforming the table into a graphic when it is being displayed on small screen devices. This is not an easy task taking into account the size and amount of data that a table can have.
Let's see an alternative solution combining the previous recipes with another plugin for rendering graphics. The main reason for this combination is we use only one plugin per page, thus optimizing our load.
This article by Fernando Monteiro, the author of the book, Instant HTML5 Responsive Table Design How-to explains what happens when we convert the data and display a nice graphic for our users using a properly formatted table.

by
Andriy Lesyuk | April 2013 | Open Source
In this article by Andriy Lesyuk, author of Instant Google Drive Starter, you will learn how to install and customize Redmine.
For installing Redmine from a package we will use Ubuntu Server 12.04 LTS. Why Ubuntu? Because it's one of the most popular Linux distributions nowadays and Ubuntu is widely used along with Redmine (for example, the TurnKey Linux is also based on Ubuntu).

-
Creating a message-logging component
-
Adding properties to the components that appear in the Object Inspector window when a component is used in design time
-
Adding events of the components that appear in the Object Inspector window when a component is used in design time
-
Learning the basics of creating a Property Editor window
-
Learning the basics of creating a Component Editor window and looking at the TCheckListBoxComponentEditor component are some examples
So let's begin.

by
Francisco J. Blanco-Silva | April 2013 | Open Source
In this article by Francisco J. Blanco-Silva, the author of Learning SciPy for Numerical and Scientific Computing, we will cover the routines in the scipy.spatial module that deal with the construction of triangulations of points in spaces of any dimension, and the corresponding convex hulls. The procedure is simple; given a set of m points in the n-dimensional space (which we represent as an m x n NumPy array), we create the scipy.spatial class Delaunay , containing the triangulation formed by those points.
