If you’ve never attended one of Apple’s Worldwide Developer Conferences (WWDC), you may want to check out the sample sessions recorded at last year’s event. The videos (which require QuickTime 6 or later) include: “Tuning Software with Performance Tools,” “Introduction to Developing Applications with Cocoa,” “How to Write a Modern Carbon Application,” “OpenGL Optimizations,” “Mac OS X Server Overview,” “Creating Great Java Applications on Mac OS X,” and “The Pro in QuickTime Pro.” You can view additional sessions by joining the Apple Developer Connection (ADC) or by logging in to the ADC Member Site and selecting “View ADC TV – WWDC 2003 Sampler.”
