Creating Intelligent Content with Lightweight DITA documents the evolution of the Darwin Information Typing Architecture (DITA) - a widely used open standard for structuring technical content. DITA has grown in popularity and features since its origins as an internal grammar for structuring technical documentation at IBM. This book introduces Lightweight DITA (LwDITA, which should be read as "Lightweight DITA") as a proposed version of the DITA standard that reduces its dependence on complex Extensible Markup Language (XML) structures and simplifies its authoring experience. This volume aims to reconcile discrepancies and similarities in methods for authoring content in industry and academia and does so by reporting on DITA's evolution through the lens of computational thinking, which has been connected in scholarship and media to initiatives for learning to code and programming. Evia's core argument is that if technical communicators are trained with principles of rhetorical problem solving and computational thinking, they can create structured content in lightweight workflows with XML, HTML5, and Markdown designed to reduce the learning curve associated with DITA and similar authoring methodologies. At the same time, this book has the goal of making concepts of structured authoring and intelligent content easier to learn and teach in humanities-based writing and communication programs. This book is intended for practitioners and students interested in structured authoring or the DITA standard.

Do you enjoy writing software, except for the database code? "Hibernate: A Developer's Notebook" is for you.

Database experts may enjoy fiddling with SQL, but you don't have to--the rest of the application is the fun part. And even database experts dread the tedious plumbing and typographical spaghetti needed to put their SQL into a Java program. "Hibernate: A Developers Notebook" shows you how to use Hibernate to automate persistence: you write natural Java objects and some simple configuration files, and Hibernate automates all the interaction between your objects and the database. You don't even need to know the database is there, and you can change from one database to another simply by changing a few statements in a configuration file.

"Hibernate: A Developer's Notebook" walks you through the ins and outs of using Hibernate, from installation and configuration, to complex associations and composite types. Two chapters explore ways to write sophisticated queries, which you can express either through a pure Java API, or with an SQL-inspired, but object-oriented, query language. Don't let that intimidate you though: one of the biggest surprises in working with Hibernate is that for many of the common real-world application scenarios, you don't need an explicit query at all.

If you've needed to add a database backend to your application, don't put it off. It's much more fun than it used to be, and "Hibernate: A Developer's Notebook" shows you why.

Here's what a few reviewers had to say:

"I'm sitting on an airplane after finishing "Hibernate: A Developer's Notebook," It's rare to find a book on a new Java technology that you can get through on a domestic flight. Thatthis notebook effectively and succinctly tackles object-relational mapping makes it, and Hibernate, even more impressive. Many books in this category would need to be checked luggage. With this book, you travel first class." --Mike Clark

"A simple persistence framework deserves a simple book, and this one delivers. The examples are well described and easy to understand, yet sophisticated enough to demonstrate Hibernate in a real-world context. Jim, I'm a new fan." --Bruce Tate

IT-Projekte haben in vielen Unternehmen eine zentrale Bedeutung. Sie binden Ressourcen und generieren entsprechende Kosten. Im Durchschnitt werden in Unternehmen 33 Projekte pro 1000 Mitarbeitern durchgefuhrt und pro Mitarbeiter und Jahr EUR 8.000 in IT-Projekte investiert. Von diesen Projekten werden weniger als die Halfte erfolgreich abgeschlossen.

An theoretischem Wissen respektive an der Ausbildung kann es nicht liegen. Aus Sicht der Autoren fehlt es den Projektmanagern oft an der notwendigen Reflexion, dies besonders wenn die Projekte in kritische Phasen treten. Ein Erfahrungsaustausch zwischen den Projektleitern findet vielfach aus zeitlichen Grunden nur unvollkommen statt. Hier setzen die Autoren an. Sie legen das Schwergewicht auf die kritischen Erfolgsfaktoren eines IT-Projekts. Gegliedert nach Erfolgsfaktoren fuhrt das Buch zum Thema und veranschaulicht Losungswege anhand von Beispielen aus der Praxis.

Smart web developers will tell you that the sooner you detect your code mistakes, the quicker you can fix them, and the less the project will cost in the long run. Well, the most efficient way to detect your mistakes in PHP is with PHPUnit, an open source framework that automates unit testing by running a battery of tests as you go. The benefits of PHPUnit are significant, they are: a reduction in the effort required to frequently test code; fewer overall defects; added confidence in your code; and improved relations with your open source teammates. The only problem with this popular testing tool was its lack of documentation-until now, that is. For this, "O'Reilly" went right to the source, as Sebastian Bergmann, the author of "PHPUnit Pocket Guide", also happens to be PHPUnit's creator. This little book brings together hard-to-remember information, syntax, and rules for working with PHPUnit. It also delivers the insight and sage advice that can only come from the technology's creator. The coverage of testing under agile methodologies and Extreme Programming (XP) is also included. The latest in "O'Reilly's" series of handy Pocket Guides, this quick-reference book puts all the answers are right at your fingertips. It's an invaluable companion for anyone interested in testing the PHP code they write for web applications.

It's been known for years that usability testing can dramatically improve products. But with a typical price tag of $5,000 to $10,000 for a usability consultant to conduct each round of tests, it rarely happens.
In this how-to companion to "Don't Make Me Think: A Common Sense Approach to Web Usability," Steve Krug spells out a streamlined approach to usability testing that anyone can easily apply to their own Web site, application, or other product. (As he said in "Don't Make Me Think," "It's not rocket surgery.")
Using practical advice, plenty of illustrations, and his trademark humor, Steve explains how to:
Test any design, from a sketch on a napkin to a fully-functioning Web site or applicationKeep your focus on finding the most important problems (because no one has the time or resources to fix them all)Fix the problems that you find, using his "The least you can do" approachBy paring the process of testing and fixing products down to its essentials ("A morning a month, that's all we ask"), "Rocket Surgery" makes it realistic for teams to test early and often, catching problems while it's still easy to fix them. "Rocket Surgery Made Easy" adds demonstration videos to the proven mix of clear writing, before-and-after examples, witty illustrations, and practical advice that made "Don't Make Me Think" so popular.
