2003 MySQL User Conference
I spoke at the MySQL User Conference in San Jose, California (April 10-12, 2003). The talk focused on using MySQL with the Ruby programming language. The presentation covered both the low-level Ruby MySQL module and the Ruby DBI module.
The slides from the presentation itself are available here. If you were not able to attend the conference or want additional information about MySQL and Ruby, I've written a couple of articles on the subject that you can read here.
