This document discusses using jQuery and CakePHP together for web development. It describes how jQuery can be used to simplify tasks like including JavaScript files and passing data from controllers to views. The author proposes using "jayDom", which involves encoding data in HTML microformats for semantic encoding and easy parsing between the browser and server via Ajax. Real-world examples are provided to illustrate accessing and updating microformat data with jQuery selectors. The goal is to more easily achieve "world domination" by building powerful applications with these techniques.
