We are a group of users focused on expanding the breadth and depth of Groovy and Grails development skills with our members who live and work in the DFW area. Our meetings are on the 1st Wednesday of every month (social & food at 6:30pm, meeting content at 7:00pm) at the NEW Improving office in Plano.

General Announcement

Starting with the June 2017 meeting we will be focusing on introducing new members to Groovy. We will have a series of talks that will bring them up to speed on Groovy, Gradle, Grails and application development. Please bring your friend, neighbor and co-worker, especially if they are familiar with Java, as the ramp-up is very easy.

Multi-Threading and Concurrency in Groovy

05 December 2012David Clark


December’s Groovy User’s Group meeting will focus on multi-threading and concurrency in groovy. The presentation will focus on two areas: 1) Tools standard Groovy gives to make multi-threaded programming easier and less error prone and 2) The [GPars] framework which simplifies making common programming tasks concurrent. The presentation will be code and audience driven. If you don’t even know how to launch a new thread in groovy, we can cover that. If you are a multi-threading maniac and want to talk about the inner workings of JDK 7’s Fork/Join framework, we can cover that too. Please bring your laptop for playing with and using the code samples. It’s best if you have JDK 7 and Groovy 2 installed, but a lot of the examples will run with little to no modifications with lower versions.
