Resolve common concurrency problems with GPars
The shift toward multicore processing has fueled an interest in concurrent programming models like fork/join, actors, agents, and executors. While these models originated within different programming languages, many of them are encapsulated in GPars, a Groovy-based concurrency library. With Alex Miller as your guide, learn how to resolve concurrency problems using techniques drawn from both the functional and object-oriented programming worlds — and do it all using Groovy's familiar, Java-friendly syntax.

Learning FC++: The C++ functional programming library
C++ is usually synonymous with object-oriented programming (OOP), and further replenished in no small measure by popular technical literature. This article tries something different—functional programming with C++ using the open source FC++ library from Yannis Smaragdakis and Brian McNamara. Learn how you can use FC++ to implement basic functional programming.
Evolutionary architecture and emergent design: Building DSLs in Groovy
Internal DSLs are possible but cumbersome in the Java language because of its restrictive syntax. This article covers some of the capabilities you can exploit and issues you'll encounter when using Groovy to build internal DSLs.
5 things you didn't know about Java Database Connectivity
JDBC, or Java Database Connectivity, is one of the most frequently used packages in the entire JDK, and yet few Java developers use it to its fullest — or most up-to-date — capacity. This article offers an introduction to newer JDBC features.
Java development 2.0 Cloud storage with Amazon SimpleDB
In Part 1 of this introduction to SimpleDB, you will learn how to leverage Amazon's own API to model a CRUD-style racing app. In Part 2 Learn how to refactor the racing application from Part 1 to be compliant with the JPA specification. Then you'll port the app to SimpleJPA, which implements a subset of the Java Persistence API.

Evolutionary architecture and emergent design: Leveraging reusable code - Part 2
Once you identify idiomatic patterns in code, the next step is to harvest and use them. Understanding the relationship between design and code can facilitate the discovery of reusable code. In Part-2 learn two techniques for harvesting idiomatic patterns: capturing patterns as APIs and using metaprogramming techniques.
Evolutionary architecture and emergent design: Leveraging reusable code - Part 1
Once you identify idiomatic patterns in code, the next step is to harvest and use them. Understanding the relationship between design and code can facilitate the discovery of reusable code. In Part-1, learn the relationship between code and design.
Gourmet Java technology for Android applications
Java language is the tool of choice for Android developers. The Android runtime uses its own virtual machine, Dalvik, which is not the usual Java virtual machine that most Java developers are used to. In this article you will learn advanced Java features and how they are implemented on Android. This includes features such as concurrency, networking, and database access.
5 things you didn't know about Java performance monitoring
Blaming bad code won't help you find performance bottlenecks and improve the speed of your Java apps, and neither will guessing. This article directs your attention to tools for Java performance monitoring, Here's five tips for using Java 5's built-in profiler, JConsole, to collect and analyze performance data.
