The golbXAJA software this blog runs on was written as a proof-of-concept two years ago. I had some ideas I needed to test out with how to handle a complete AJAX page, dynamic loading, etc, while still maintaining full non-AJAX compatibility, Google's ability to index the pages, and being able to copy/paste the address in the address bar and actually get to the right place.

It was built using HTML/JavaScript/CSS (obviously), jQuery, PHP, my own O/R mapper/database/CMS generator framework for PHP and ChainfireBuild. Total build time was about 72 hours.
