Unfortunately, I missed this big news a couple weeks back: Grails has gone 1.0 RC1. Congratulations to Graeme Rocher and the entire Grails community for this major milestone. I’ve experimented with Grails and have kept up with the platform’s progress for the last 18months or so. And getting to 1.0 has been a long, hard slog.

Grails is what allows you to leverage that giant portion of your abilities that is deeply invested in Java web app technology, but while operating in an efficient, sensible, and pleasant Groovy scripting mode. And it’s what will allow a lot of developers to remain in the Java ecosystem, instead of turning, for some good reasons, to RoR.

For this Grails alternative, and a quantum of taming the Java web app development process, we owe Graeme and the team a healthy dose of gratitude.

Nice job, all.

Oscar Celma and Paul Lamere have put together a worthwhile set of slides on the art and science of music recommendation. The slides speak to two important themes as it relates to music in our lives: how to find new music for your own listening enjoyment, and how “Music 2.0″ commercial plays can help you find the same.

These slides are full of fascinating data and observations, but close with perhaps its most compelling: music discovery is in its pre-Google stage. Much work remains to be done, and, like Google’s ascendance, some winner is waiting to take a huge slice of this business.
