Grails is a Java- and Groovy-based web framework that is built for speed. First-time developers are amazed at how quickly you can get a page-centric MVC web site up and running thanks to the scaffolding and convention over configuration that Grails provides. Advanced web developers are often pleasantly surprised at how easy it is to leverage their existing Spring and Hibernate experience.
"Getting Started with Grails" brings you up to speed on this modern web framework. Companies as varied as LinkedIn, Wired, Tropicana, and Taco Bell are all using Grails. Are you ready to get started as well?

Brian Marick takes us through a quick tour of the most important values and challenges to adopting Agile successfully (they aren't the typical challenges and values we hear in the community).
The line between development and architecture is tricky. Does it exist at all? Is an ivory tower actually needed? There's a balance in the middle, but how do you move from developer to architect?
The word 'authority' sometimes produces an allergic response in hard-line agilists. Freedom and authority – both are bad if misused and both are good if used in right spirit for a noble cause.

Those familiar with only ITIL V2 often scoff at the thought that ITIL could serve as a governance framework for SOA. With ITIL V3, the focus of the framework shifted towards service-orientation.
SpringSource CTO Adrian Colyer discusses AspectJ, SpringSource's dm Server and tc Server products, OSGi and Scrum.
Heroku's Adam Wiggins talks about Rails, Background Jobs, Add-Ons, Ruby, and how Heroku manages to work around Ruby's inefficiencies using Erlang and other languages.
For Grady Booch the foundation of a good architecture is patterns, SOA being just one of many patterns. In this Second Life presentation, Booch attempts to bring more clarity on what architecture is.
