When it comes to creating dynamic web sites, the open source PHP language is red-hot property: used on more than 20 million web sites today, PHP is now more popular than Microsoft’s ASP.NET technology. With our Cookbook’s unique format, you can learn how to build dynamic web applications that work on any web browser. This revised new edition makes it easy to find specific solutions for programming challenges.
PHP Cookbook has a wealth of solutions for problems that you’ll face regularly. With topics that range from beginner questions to advanced web programming techniques, this guide contains practical examples — or “recipes” — for anyone who uses this scripting language to generate dynamic web content. Updated for PHP 5, this book provides solutions that explain how to use the new language features in detail, including the vastly improved object-oriented capabilities and the new PDO data access extension. New sections on classes and objects are included, along with new material on processing XML, building web services with PHP, and working with SOAP/REST architectures. With each recipe, the authors include a discussion that explains the logic and concepts underlying the solution.

Though we don’t like to admit it, all hackers churn out bad code from time to time. But most coders worth their salt also have it in them to produce software that is truly elegant without sacrificing practicality. Because we value our craft, its important to know the difference between code that is agile, and code that is fragile.Ruby Best Practices aims to help Ruby developers from a wide range of skill levels improve their fundamental understanding of the language via exposure to the common practices and idioms that many seasoned Rubyists take for granted. With a strong emphasis on exploring real codebases, and an understanding that beautiful solutions depend heavily on context, this book lays out a clear road map to Ruby mastery for those who wish to pursue it.

“Invent Your Own Computer Games with Python” is a free e-Book that teaches you how to program in the Python programming language. Each chapter gives you the complete source code for a new game, and then teaches the programming concepts from the example. “Invent with Python” was written to be understandable by kids as young as 10 to 12 years old, although it is great for anyone of any age who has never programmed before. This second edition has revised and expanded content, including using the Pygame library to make games with graphics, animation, and sound.

The GNU/Linux systems have reached an important level of maturity, allowing to integrate them in almost any kind of work environment, from a desktop PC to the sever facilities of a big company.
In the module called “The GNU/Linux operating system”, the main contents are related with system administration. This book is the main documentation for the module.
We will learn how to install and configure several computer services, and how to optimise and synchronise the resources.
The activities that will take place in this module cover the studied topics in a practical approach, applying these concepts in real GNU/Linux systems.

The FTA has reused existing course materials from the Universitat Oberta de Catalunya (UOC). The first version of this course book was published in 2004 for the Master Programme in Free software of the UOC. In 2008, this book was translated into English with the help of the SELF (Science, Education and Learning in Freedom) Project, supported by the European Commission’s Sixth Framework Programme. In 2009, this material has been improved by the Free Technology Academy. Additionally the FTA has developed a study guide and learning activities which are available for learners enrolled in the FTA Campus.

Ruby has taken the programming world by storm. With the slow decline of Java and the catalyst of Rails, it has risen to become one of the most popular programming languages, rising to #10 on the TIOBE index and winning their “Programming Language of the Year” award.
