Steven Saunders, Macquarie University

Audience: Beginner

Abstract:

Debugging memory related bugs can be a time-consuming and headache-inducing process. A solid grasp on the principles of memory management is key to avoiding these annoyances. In this presentation participants will develop a detailed understanding of Cocoa’s retain/release/autorelease system and the memory ownership issues it is designed to address.  Attendees will also learn how to adopt Cocoa’s garbage collection facility, and how it relates to reference counting. The use of tools like Instruments and Guard Malloc to track down memory leaks, as well as memory-smashing and doubly-freed-memory bugs will also be covered.

Josh Anon, Pixar

Just as how buildings grew from just being a simple shelter against the elements to entire created experiences and how writing went from written laws to libraries of novels, software is undergoing a shift from being focused on utility to being about experiences.  While not immediately obvious, building software has come to have a lot in common with seemingly unrelated artistic fields, like creating a movie.  Josh Anon will discuss the growing role of telling a good story and providing an experience in software.
