This is the version of my Create talk I gave at Railsconf 2009.
Sometimes the best solution is a standalone application that you can give to a client or customer to just drop on a machine and run. Maybe it is a web service, or a desktop data entry application, or mass deployed background agent, or you have no control of the deployment environment. In any case, there are situations where deploying a full ruby stack may not be an option.
This talk will cover the Crate project and how it may be used to package your application, be it commandline, server, or web application. The end result is a statically built, standalone executable of the ruby interpreter and all dependent binary extensions. The application code, ruby stdlib, dependent gems, and other assets are packed into one or more SQLite databases.
