Any recommendations for a good book about Alfresco Development, including the basic concepts / philosophy Alfresco is built upon?
I plan to dive into Alfresco, especially web development. So far I'm not familiar with Alfresco. I've tried the public Alfresco Share trial site. I am familiar with SharePoint Development, and I wonder how it's like to develop on Alfresco.
(Clarification: I don't want to develop in the sense of contributing to the Alfresco open source core, but to leverage Alfresco's extensibility options to develop Alfresco-based web applications.)
