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.

Adding Geographic Capabilities via the GeoPlaces Theme
by
Yuxian Eugene Liang | January 2013 | Open Source
In this article, by Yuxian Eugene Liang, the author of WordPress Mobile Applications with PhoneGap, talks about creating a location-based directory via the GeoPlaces theme. It covers the setting up and addition of sample geographic data into your WordPress site. We'll add geographic capabilities to our WordPress site by leveraging on the GeoPlaces theme.
The major topics we will cover in this article are:
-
Introduction to the GeoPlaces theme
-
Populating the site with sample data from GeoPlaces
-
Managing place listings from the frontend side as well as the admin side of the site
For a start, we'll be using a premium theme called GeoPlaces, by Templatic. At the time of writing, a single user license is priced at USD 99 while a developer license is priced at USD 179. For the rest of this article we will be using the GeoPlaces theme to do the bulk of the heavy lifting of geographic functionalities, since Google Maps are built directly into the GeoPlaces theme.
Before we move into this article officially, you might be wondering where it will lead us. To begin with, since our mobile app's content is dependent on our WordPress site, we need to add basic content (in this case, place listings and other article-like information) to the site.

Robert Varkonyi | January 2013 | Drupal Open Source
This article by Robert Varkonyi, author of Drupal Rules How-to, explains the benefits of using Components by creating a Condition that can be re-used in other rule configurations.
In this scenario, we want to perform some action when a node is being commented on. But we only want to execute the action if the node was not created by the super admin (that is, user 1) and the node is either an article, or has an image field (field_image).

Ajit Kumar | December 2012 | Open Source
In this article by Ajit Kumar, author of Sencha MVC Architecture, we will take a step-by-step approach to create a functional application in ExtJS using the MVC architecture and the framework classes related to it. For the sake of completeness and illustration of the concepts, we will be taking up an application requirement and implementing it in ExtJS.
As a requirement, we will be creating an application, which would:
-
Show the list of departments and the users
-
Show the list of users for a selected department
-
Allow the user to edit user information
-
Refresh the users list to get all the users of all the departments

by
Ivan Idris | December 2012 | Cookbooks Open Source
In this article by Ivan Idris, the author of NumPy Cookbook, we will learn some of NumPy's more advanced and tricky indexing techniques. NumPy has very efficient arrays that are easy to use due to their powerful indexing mechanism. NumPy is famous for its efficient arrays. This fame is partly due to the ease of indexing. We will demonstrate advanced indexing tricks using images.
In this article, we will cover:
-
Installing SciPy
-
Installing PIL
-
Resizing images
-
Comparing views and copies
-
Flipping Lena
-
Fancy indexing
-
Indexing with a list of locations
-
Indexing with booleans
-
Stride tricks for Sudoku
-
Broadcasting arrays
Before diving into indexing, we will install the necessary software — SciPy and PIL. Some of the examples in this article will involve manipulating images. In order to do that, we will require the Python Image Library (PIL); but don't worry, instructions and pointers to help you install PIL and other necessary Python software are given throughout the article, when necessary.
