     Topic:  AJAX and other Advanced JavaScript Techniques

  Speaker:   Dan Phiffer


   This month's meeting will continue on the Web Technologies theme
   we started a few months ago when we covered LAMP (Part 1) - MySQL.

   AJAX is a JavaScript technique that has become required learning
   for anyone building the new generation of web applications.
   Behind all the hype is a practical workhorse that can actually
   make web applications more useful.

   AJAX seems to be a very hot topic right now... from SlashDots
   and Google Maps, to magazine articles and professional seminars...
   just look and you are bound to find something being said about
   AJAX on a daily basis.  It seems like a great time to hold
   this meeting!
