Well, I hope all you guys had a great weekend - now back to work! (bleh) Anyway, I have two links for you this morning, one from arts and one I turned up.
First off, arts submitted a link to an article that discusses Tuning MySQL performance, but not through the server really. This is more about good script-writing to make the load easier on your server and to make things work a bit better all around. It's nice to see a different approach to the whole "tuning" issue - that the programmer should be more responsible for his actions, and not just the software.
Second, we have part two of Zend's Code Gallery Spotlight on the shopping cart script. Last time, they just got into the basics and all of the scripts - now they start getting into the meat of it all and showing you how to get some sample code working. Enjoy!
