Collaboration is one of the key strengths of the Open Source world, which leads to user-centric software developments, quicker development cycles and reduced product costs. LinuxDays 2009 provides an environment to foster collaboration through knowledge sharing, facilitated discussions with real deliverables and opportunities to network with others that have either « been there and done it », are in the process of planning, developing and implementing, or are providing technology and professional services to help organisations leverage from open source assets.
