Low-cost and high-performing, with a massively diverse range of uses and applications, the Raspberry Pi is set to revolutionize the way we think about computing and programming. Using it as a media center allows everyone to have a low-cost device that is always on and attached to their TV.
In this article by Sam Nazarko, the author of Raspberry Pi Media Center, we'll look at the following topics:
What PVR allows us to do
The different types of PVR setups that Raspbmc supports
How to set up Raspbmc to take advantage of PVR
This article by Erik Westra the author of Python Geospatial Development - Second Edition, examines a number of libraries and other tools which can be used for geospatial development in Python.
More specifically, we will cover:
Python libraries for reading and writing geospatial data
Python libraries for dealing with map projections
Libraries for analyzing and manipulating geospatial data directly within your Python programs
Tools for visualizing geospatial data
Note that there are two types of geospatial tools which are not discussed in this article: geospatial databases and geospatial web toolkits. Both of these will be examined in detail later in this book.Read Python Libraries for Geospatial Development in full
We have discussed many of the core concerns of small and big business. Let's turn our eyes now to other concepts that would concern media companies.

Security is a process that requires the integration of security into business processes to ensure enterprise risk is minimized to an acceptable level. Security as a process is an approach that highlights the integration of security and business initiatives to reduce the security impact of implementations and changes to the enterprise environment. This article by Aaron Woody, author of Enterprise Security: A Data-Centric Approach to Securing the Enterprise, will introduce the concept of using risk analysis to drive security decisions.Read An Introduction to Risk Analysis in full
Starting with the release of Xcode 4.2 and iOS 5, developers and designers now have the ability to lay out the workflow of their applications using the new storyboards feature that has been incorporated as part of the XIB editor in Xcode.
Instead of creating numerous interface files, you can now start dragging and editing all your views in one place with the ability to specify transitions between screens and the associated actions that trigger them.
In this article by Steven F. Daniel, who has also authored the book Xcode 4 Cookbook, we will be gaining an understanding of what storyboards actually are, and how they require iOS 5 or later, as well as familiarizing ourselves with the new work flow that has been implemented within the XIB editor within Xcode.Read Using Storyboards in full

In this article by Andrey Kovalenko, the author of the book, Instant KineticJS Starter, we will learn about the basics of KineticJS.
In this article by Ram Kulkarni author of Instant Eclipse 4 RCP Development How-to [Instant], we will create a pop-up menu that will be displayed when you right-click in the snippets list. If no snippet is selected at a location where you right-click, then we will display a pop-up menu with a single option to add a snippet. If there is a snippet at the location, then we would display a menu that has options to delete the snippet and add a snippet.Read Creating a pop-up menu in full
Play is a full-stack web framework created to make web application development on the JVM easier and more productive. It provides APIs for Java and Scala.
A full-stack web framework provides solutions for a wide range of time-consuming web development tasks. With Play, developers are focusing on implementing functionality instead of thinking about design and architecture, and re-inventing the wheel. Only a few lines are necessary to write a fully functional web application.
Traditional web frameworks running on the JVM tend to create an abstraction layer over another abstraction layer. These heavy-weight lasagne architectures introduce an additional technical boilerplate and configuration, distracting developers from reaching their goal. Play in turn reduces complexity and simplifies web development by aligning its architecture with the that of the web, instead of abstracting it away.
Users of the Play Framework are web developers. Developers care about code readability and maintainability, fast development cycles, and easy error recovery. Play was designed by web developers to meet these goals.
Play consists of well-known parts. The basic architecture of a Play application follows the model-view-controller pattern, having an HTTP interface at its heart. Cohesive controllers and composable views share the same model.
Code changes are made visible by a simple reload of the web page in the browser. Play takes care of compiling changes in the background, independent of the development environment. This makes the development turnaround fast and easy.
Play also takes care of errors. Developers don't have to read long JVM stack traces to locate an error. Instead, Play shows the significant information directly in the browser, leading the developer right to the origin of the error. It is a big advantage that Play is a JVM framework; almost all parts of a Play application are type-safe.
This is why it is fun to develop Play applications.
In this article by Daniel Dietrich author of Instant Play Framework Starter, we will see how easy it is to create new Play applicationRead So, what is Play? in full
In this article we're going to change the layout of the site we've created. To achieve this, we will convert an HTML file into a concrete5 theme. This means that we have to replace and insert a few lines of PHP code to make things a bit more dynamic. However, you'll see that the basic conversion process is rather easy and quick; creating a concrete5 theme does only require very little PHP skill and almost no time.
Some code snippets are just modifications to other snippets in this article. If you want to re-create the theme code on your own, you have to follow each step and follow the instructions precisely. If you're in a hurry, at the end of the article you'll find a link from where you can download the final code used in this article.
In this article by Remo Laubacher, author of concrete5 Beginner's Guide - Second Edition, you'll learn how to create concrete5 themes by going through the follow topics:
A simple example showing you how to convert an existing HTML to a concrete5 theme
An explanation and more examples about page types
A number of snippets that can help you to get more out of your theme
An example that shows you the use of attributes to add a page-specific background picture
How to use customizable styles to allow certain CSS properties to be changed in the dashboard

One of the key aspects of mobile technology is the ability to tie different systems together into a meaningful application. More and more companies are allowing access to their programs and data through an Application Programming Interface or API. These APIs include things such as:
Maps via Google, Yahoo, and other providers
Music applications such as Rdio and Spotify
Location aware data providers such as Foursquare
Social networks such as Facebook and Google Plus
Photo services such as Flickr and Picassa
You can get a rough idea of what is available, at http://www.programmableweb.com/apis.
This is just a small sampling of the data available to make your application more useful. The trick is how to get the data and how to use it. In this article we will be using the Foursquare API to explore the use of these types of APIs and how to get started.
In this article by John Earl Clark and Bryan P. Johnson, authors of Creating Mobile Apps with Sencha Touch 2, We will talk about:
An overview of external APIs
Getting started with the Foursquare API
Building the basic application
Loading a data store with information from Foursquare
Displaying the data to the user
We will start with a general look at how external APIs generally work and what you need to get started with one.Read The Decider: External APIs in full
