SQL NOT IN and NULL still will not work
Last night I had another instance where doing a:
SELECT * FROM
TBL WHERE ID NOT IN (SELECT ID FROM TBL2)
would fail every time to return any rows.

Rotating Ad Sense Ads on AJAX Calls?
Here is a link to an article discussing the ways you can reload google adsense ads when the user is doing something AJAXey, or really, whenever.
I wonder though if google allows this type of thing in their terms. You couldn’t refresh the ad every 2 seconds, so why would they let you refresh the ad ever? How could you define when you could and couldn’t refresh an ad?
