I tried to upload my slides from the conference, but run into problems with a firewall somewhere, so they've had to wait for me to return home.
So, here we are: Using MySQL with PDO (PDF).
This was my first MySQL users conference, and it seemed to go well. Truth be told, I'm not a database fanatic (which is ironic considering my involvement with PDO), so I didn't find a lot of the material to my taste. I did learn a few things from Jim Winsteads embedded mysql talk (something I bet he'll be surprised to hear :) and also Hartmut Holzgraefe's mysqli talk. I also got to chat to Monty about the issues I mentioned and meet some new faces, including my Evil sysadmin, some old and some older faces (Hi Sterling :)
The conference was quite big; 1500 attendees, 6 tech tracks (there were a couple of other non-tech tracks too, but I forget exactly what they covered) and a lot of BOF sessions. If MySQL is your bread and butter, you might want to consider attending the next one.
