It's easy to write correct Ruby code, but to gain the fluency needed to write "great "Ruby code, you must go beyond syntax and absorb the "Ruby way" of thinking and problem solving. In "Eloquent Ruby, "Russ Olsen helps you write Ruby like true Rubyists do-so you can leverage its immense, surprising power. Olsen draws on years of experience internalizing the Ruby culture and teaching Ruby to other programmers. He guides you to the "Ah Ha " moments when it suddenly becomes clear why Ruby works the way it does, and how you can take advantage of this language's elegance and expressiveness." Eloquent Ruby "starts small, answering tactical questions focused on a single statement, method, test, or bug. You'll learn how to write code that actually looks like Ruby (not Java or C#); why Ruby has so many control structures; how to use strings, expressions, and symbols; and what dynamic typing is really good for. Next, the book addresses bigger questions related to building methods and classes. You'll discover why Ruby classes contain so many tiny methods, when to use operator overloading, and when to avoid it. Olsen explains how to write Ruby code that writes its own code-and why you'll want to. He concludes with powerful project-level features and techniques ranging from gems to Domain Specific Languages. A part of the renowned Addison-Wesley Professional Ruby Series, "Eloquent Ruby "will help you "put on your Ruby-colored glasses" and get results that make you a true believer.

More than ever, learning to program concurrency is critical to creating faster, responsive applications. Speedy and affordable multicore hardware is driving the demand for high-performing applications, and you can leverage the Java platform to bring these applications to life. Concurrency on the Java platform has evolved, from the synchronization model of JDK to software transactional memory (STM) and actor-based concurrency. This book is the first to show you all these concurrency styles so you can compare and choose what works best for your applications. You'll learn the benefits of each of these models, when and how to use them, and what their limitations are. Through hands-on exercises, you'll learn how to avoid shared mutable state and how to write good, elegant, explicit synchronization-free programs so you can create easy and safe concurrent applications. The techniques you learn in this book will take you from dreading concurrency to mastering and enjoying it. Best of all, you can work with Java or a JVM language of your choice - Clojure, JRuby, Groovy, or Scala - to reap the growing power of multicore hardware. If you are a Java programmer, you'd need JDK 1.5 or later and the Akka 1.0 library. In addition, if you program in Scala, Clojure, Groovy or JRuby you'd need the latest version of your preferred language. Groovy programmers will also need GPars.

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

About the new Developer's Notebook Series from O'Reilly:
