This year saw the release of GPLv3, the latest version of one of the most important open source licenses. Its development has led to spirited debate and reexamined what it means for a project to be open source. Is Sun's slow release of Java source code or the availability of an unsanctioned open source implementation of .Net sufficient? Like many folks, we don't take an absolutist perspective. We use the tools that work, and we celebrate open source communities for creating so many useful languages and development tools — and for making them widely available at no cost.
