  • Interview with Sandi Metz on Practical Object-Oriented Design in Ruby

    On occasion of the second edition of her book “Practical Object-Oriented Design in Ruby: An Agile Primer”, InfoQ talked with Sandi about how her book was received, learning from open source code, making sensible use of code analysis tools and other topics.

  • Refactoring Legacy Applications: A Case Study

    To refactor legacy code, the ideal is to have a suite of unit tests to prevent regressions. However it's not always that easy. This article describes a methodology to safely refactor legacy code.

  • .NET Static Analysis and Parasoft dotTEST

    Static analysis has a broad set of capabilities to offer the .NET world. It can enforce pattern-based rules, whether they're based on proven standards or custom patterns that help you identify application-specific defects. Nevertheless, some defects cannot be detected by this analysis technique. The flow analysis feature of dotTEST does exactly that.

  • Discover Recording JVM Debuggers

    A debugger is a great tool for examining the internal state of an application, reproducing however a specific issue is a completely different matter. Fully replicating the production environment into a staging area might even be a feat on its own. Meet recording debuggers that remove all the guesswork and extra effort by monitoring the application in production and knowing exactly what happened.

  • Profiling java.util.concurrent locks

    IBM’s Yao Qi, Raja Das, and Zhi Da Luo describe jucprofiler, an alphaWorks tool designed to profile multicore applications that make use of the java.util.concurrent classes introduced in Java 5.

  • Debugging in MonoTouch

    When you run into bugs in application development, it's important to be able to track them down quickly and efficiently. To this end, debuggers allow you to track your code during execution and see exactly what’s happening. This article explores how to set up, test out, and work with the MonoTouch debugger while developing iPhone applications, including debugging running applications over Wifi.

  • Book Excerpt and Interview: Effective Java, Second Edition

    Effective Java, Second Edition by Joshua Bloch is an updated version of the classic first edition, which was the winner of a 2001 Jolt Award. This edition has been updated to discuss Java 6 language features including generics, enums, annotations, autoboxing, the for-each loop, varargs, and concurrency utilities. InfoQ asked Bloch several questions about the areas that the new edition covers.

  • A Look at Ruby Debuggers

    A misconception lingers in the Ruby world: Ruby has no debugger. This is blatantly wrong - Ruby has debuggers, GUIs for debuggers and APIs for debuggers. InfoQ takes a close look at the state of debugging tools in the Ruby world - and finds that its debugging support is more than sufficient.

  • Talking .NET Code Analysis with Patrick Smacchia

    Patrick Smacchia is a Visual C# MVP with over 15 years of software development experience. He is the author of Practical .NET 2 and C# 2, books about the .NET platform. He has worked on software in a variety of fields including the stock exchange at Société Générale and a satellite base station at Alcatel. He's currently the lead developer of the tool NDepend.

  • Using singleton classes for object metadata

    So you have a bunch of objects - let's call it an object graph - provided by some API. Now you want to to process the objects - which requires some intermediate data, for instance: the process creates some metadata that needs to be stored with the objects. The problem: where to store the metadata? We'll show how to use Ruby singleton classes to handle this problem.

  • Software Testing With Spring Framework

    Srini & Kavitha Penchikala provide an overview of the support provided by Spring framework in the areas of unit and integration testing. I will use a sample loan processing web application to help the readers in implementing an Agile Testing framework in a typical Java EE application and how to use Spring test classes to test the application functionality.

  • Implementing Automated Governance for Coding Standards

    Most development organizations of a significant size have some form of coding standards and best practices. Simply documenting these standards and keeping them up to date can be a significant challenge and enforcing them even harder. Our organization has found that enforcing coding standards and best practices in an automated fashion through our build process has been highly effective.
