Based on our experiences with the LJC and other OSS projects we will cover several tips and tricks we’ve used to build a vibrant communities of thousands of passionate developers. This includes discussions on how we’ve managed to get the membership involved in the Free Java movement, how the LJC split off several child groups (Software Craftsmanship, Scala, Clojure and Jboss to name a few) and how we deal with membership conflicts.

Most importantly we cover how we treat the LJC like an open source community and how we applied Karl Fogel’s ‘Producing OSS’ concepts to manage the community, build a large team of leadership volunteers (~50) and persuade other tech communities and projects that being open, transparent and free actually provides you benefits. There are also plenty of war stories to tell, especially given a monthly pub social with free and frank exchanges of opinion from our members!
