Laura Thomson (a developer on the Ning project) has this new note on her blog today with info about her upcoming presentation at the AUUG Conference in Sydney.

I have a tutorial with Luke on Monday morning on PHP and MySQL, and a talk on Friday afternoon on PHP Security. Luke also has a talk on Friday on "Building a Simple PHP/MySQL Geographical Information System", which is quite fun.

The presentation they're giving together is on PHP and MySQL Best Practices, and they will follow each other on Friday with the "Geographical Systems" and "PHP Security" talks...
