25.05.09 Ubuntu Developer Summit for version 9.10 is beginning.
At the beginning of a new development cycle, Ubuntu developers from around the world gather to help shape and scope the next release of Ubuntu. The summit is open to the public, but it is not a conference, exhibition or other audience-oriented event. Rather, it is an opportunity for Ubuntu developers — who usually collaborate online — to work together in person on specific tasks.
Small groups of developers will participate in short Forum and Workshop (formerly called “BoF”/Birds-of-a-Feather) sessions. This allow a single project to be discussed and documented in a written specification. These specifications will be used for planning the new release of Ubuntu, as described in FeatureSpecifications and TimeBasedReleases.
