Maybe you’re a great programmer or IT professional, but marketing isn’t your thing. Or perhaps you’re a tech-savvy search engine marketer who wants a peek under the hood of a search engine optimized web site. Search engine marketing is a field where technology and marketing are both critical and interdependent, because small changes in the implementation of a web site can make you or break you in search engine rankings. Furthermore, the fusion of technology and marketing know-how can create web site features that attract more visitors.

The mission of this book is to help web developers create web sites that rank well with the major search engines, and to teach search engine marketers how to use technology to their advantage. We assert that neither marketing nor IT can exist in a vacuum, and it is essential that they not see themselves as opposing forces in an organization. They must work together. This book aims to educate both sides in that regard.

Kevin Hoang Le and his team have created an Ajax Chinese Chess game.

It’s true Ajax (as opposed to just Javascript) since all the move computations of the “computer” player is done on the server and the data is passed in JSON format back and forth.

The Javascript code is entirely unobtrusive and weights only about 30 kB (uncompressed). This code uses the excellent Mootools and JavaScript VectorGraphics libraries. On the server side, it’s built in Python using the Django framework.

Ajax Chinese Chess features the following: animation, drag and drop, fast loading (thanks to lightweight Javascript code mentioned above and small footprint Mootools), no plugin required and cross browsers/cross platforms.
