If you think AJAX is a type of clothes detergent, this post is not for you.  If you know AJAX is a web technology that stands for Asynchronous Java And XML then this post IS for you.

Thank you miCRoSCoPiC^eaRthLinG for writing (link) about this free 18-week online AJAX course, and because I'm excited about it and considering taking it I wanted to let other people know about it as well.

Boston based Sang Shin, who’s a technology architect, consultant, and evangelist at SUN Microsystems offers a free 18-week online course on AJAX.

The course commences on 18th of February, 2007 and covers some hot new topics such as the opensource javascript toolkit named Dojo, the NO-JavaScript AJAX Framework called ZK, DynaFaces - the thin application layer that renders AJAX capabilities to JSF, and Phobos - the lightweight, scripting-friendly, web application environment running on the Java platform.

More information on the course is available on his site, but if you are interested in joining, it is very simple.  "Literally anyone can sign-up for it by simply sending a blank mail to ajaxworkshop-subscribe@yahoogroups.com. There’s no eligibility criteria as such. However, it is assumed that you’ve got some prior programming experience with the common web programming/scripting languages such as JavaScript / PHP as well as core Java itself. The course will continue on a weekly basis till June 11th, 2007."
