Episode 32 - Grails discussion with Brent Baxter and Gordon Dickens

Grails is a convention over configuration web framework, written in the Groovy dynamic language and based on the widely adopted Spring and Hibernate frameworks.  In this TechCast, I sit down with Chariot's Gordon Dickens and Brent Baxter and discuss the relative merits of developing applications on the platform. We talk about the Groovy language, the productivity of building applications on the Grails platform, available plugins, and overall uses for the platform.
