Today marked the first day of the Groovy/Grails Experience, also known as 2GX, in Reston, Virginia. The conference spans three days and includes forty 90-minute sessions, panel discussions and code workshops. One of the first sessions of the day was Venkat Subramaniam's "DSL In Groovy." Domain specific languages have appeared on InfoQ in the past including an Introduction to Domain Specific Languages by Martin Fowler and Ian Roughley's article on Building Domain-Specific Languages in JRuby.
Venkat's session provided information about what DSLs are, there characteristics, the types of DSLs (internal vs. external), as well as, the Groovy features for creating and using them. Venkat primarily focused on creating internal DSLs using some of Groovy's built-in features:
Besides these three features Venkat discussed the lack of constraints that Groovy places on developers and additional features that promote DSLs including:
- Categories allows you to tactically enhance a class
- ExpandMetaClass is far reaching, global in nature
- You may not want to affect a class globally
- Categories provide controlled flexibility
Domain specific languages are continuing to stay in the spotlight and can be created and used with Groovy with its built-in features.

VMware Infrastructure 3: Advanced Technical Design Guide and Advanced Operations Guide provides a wealth of practical insights into setting up virtualization in todays corporate environments.
Ruby 1.9's Fibers and non-blocking I/O are getting more attention - we talked to Mohammad A. Ali of the NeverBlock project and Tony Arcieri of the Revactor project.
Tim Mackinnon talks about the aspirations behind the Agile principles and practices, the desire to become efficient, to write quality code which does not end up being thrown away.
Brian Goetz discusses the difficulties of creating multithreaded programs correctly, incorrect synchronization, race conditions, deadlock, STM, concurrency, alternatives to threads, Erlang, Scala.
Often the hardest part of changing technologies is language syntax differences. This new article provides Java developers with a transition guide to Actionscript which forms the foundation of Flex.
Neal Ford talks about having multiple languages running on one of the two major platforms: Java and .NET. He also presents the advantages offered by Ruby compared to static languages like Java or C#.
David Anderson talks about the history of Agile, the current status of it and his vision for the future. The role of Agile consists in finding ways to implement its principles.
Nick Sieger talks about the future of JRuby, Java Integration, and his work on JEE deployment tools for Ruby on Rails like Warbler.
