An open geo-stack offers a flexible and feature filled solution for your web mapping needs. Store your data with PostGIS, set up GeoServer to publish it, and develop an OpenLayers based client for the browser. This tutorial will focus on these three core components of an open source geo-stack and will also cover architectures that cross the proprietary/open source divide.
If you’re interested in learning more about the complete stack of open source software you can use to publish geographic data over the web with versioning, interested in learning a bit more about the server behind some OpenLayers applications, or just want to refresh yourself on the technology around OpenLayers in general, this looks like it may of interest if you plan to be at Where 2.0.
