  • JRuby 1.7.0 Released: Defaults to Ruby 1.9 Mode, Can Use InvokeDynamic

    JRuby 1.7.0 now defaults to Ruby 1.9 mode and supports almost all of 1.9's features. On recent JVM implementations that support invokedynamic, using JRuby 1.7 can increase application performance.

  • Community-Driven Research: Top 20 Web Frameworks for the JVM

    InfoQ's research initiative continues with an 10th question: "Top 20 Web Frameworks for the JVM". This is a new service we hope will provide you with up-to-date & bias-free community-based insight into trends & behaviors that affect enterprise software development. Unlike traditional vendor/analyst-based research, our research is based on answers provided by YOU.

  • Scala Adding Macros to the Language

    The team behind Scala is adding an experimental version of macros in the forthcoming release version 2.10. Scala macros provide an advanced form of compile-time meta-programming.

  • CRaSH: An Extensible Command Line Shell For Monitoring A Running JVM

    The Common ReusAble SHell (CRaSH) is an interactive shell (with history support and autocompletion) that attaches to a running JVM and can execute several commands for retrieving JVM statistics or changing JVM internals on the fly. It can be used for remote monitoring and administration of existing Java applications and it is fully extensible via custom Groovy scripts.

  • An Alternative Build System: Gradle 1.0 Released

    Gradle 1.0, a build system powered by a Groovy DSL, has been released. Gradle is compatible with Ant tasks, Maven repositories, and has support for the popular IDEs. It attempts to find the sweet spot between the flexibility of Ant and convention-over-configuration of Maven.
