Apple has increased the number of Coding Headstarts that they have available to 19. They are designed to help developers get the most out of the upcoming WWDC event. The tutorials provide “step-by-step guidance on creating new and compelling features using the development languages, APIs and frameworks of Mac OS X Leopard”.
To see the introductory video you can log on to ADC on iTunes. To access the full set of Coding Headstarts you’ll need to be registered for WWDC 2007.
