A while back I wrote a series dealing with loading content and JSON data with jQuery and AJAX which culminated in the post "Load JSON data with jQuery, PHP and MySQL" which brought all the techniques together and loaded JSON data into select boxes when the first was changed.

If you’ve moved a MySQL installation from one Debian server to another and/or replaced the user logins on your system, you might get the error message "ERROR 1045 (28000): Access denied for user ‘debian-sys-maint’@’localhost’ (using password: YES)" when attempting to restart MySQL.
Apache 2.x keeps child processes alive by creating internal connections which appear in the log files as "internal dummy connection" on the IP address ::1 or 127.0.0.1. If you ever monitor Apache log files you’ll see a lot of these in the log files. This post shows how to prevent logging for these two IP addresses so your log files won’t get filled up with these.
