If you're in or near Amsterdam in the second week of April, come on over to ApacheCon EU, the 2008 European conference of the Apache Software Foundation. There are a lot of interesting speakers and sessions going on, not all of them technical (for example, "Open Source Business in Europe" by Arje Cahn).
I'll be giving a talk entitled Creation Myths: Three Centuries of Open Source and Copyright, on Wednesday, 9 April, at 5:30pm. It's about the similarities between today's open source movement and the creative world of the pre-copyright era, how copyright and centralized distribution gradually changed the nature of creativity, and how open source and decentralized distribution are changing it back again — but with some new twists. (This is an updated version of a talk I gave last summer at OSS2007 in Ireland.) We'll also look at some non-software business models based on unrestricted information flow and collaboration.
