Justin and I provide operational support to the SME Toolkit project, an education portal for small to medium sized enterprises in developing countries sponsored by the IFC (which is the private sector development branch of the World Bank Group).
Recently, the source code for the Rails-based web application was migrated from Subversion to Git. This also changed how we deploy the application. Previously, we deployed a snapshot of code from a tarball placed on a bastion server. With a few changes to our Capistrano configuration, we are able to deploy directly from the source code repository.
