Helpful Tuturials

I thought it might be good to have a thread where people can post links to helpful tutorials.

Here is one that I found yesterday which I think is useful for integrating in affiliate coupon deals.

Most affiliate networks have and API for getting a coupon feed, but that feed rarely changes through the day, so there is no need to blast it thousands of times a day. Instead you can setup a cache for a particular coupon feed. This tut also includes info on using YQL to query a variety of APIs. I highly recommend adding NetTuts to your RSS reader, they have a ton of great PHP and Javascript/jQuery tutorials. CSStricks.com is another great site.
