Oftentimes, what separates an average developer from a great developer is the ability to debug. When faced with software that Just Doesn't Work, how do you go about finding the problem quickly and fixing it? In this session we'll cover some tools and techniques that can improve your debugging chops.

We all want our apps to perform better.  Run faster.  Consume less memory.  Burn less battery.  Sometimes it's hard just to figure out what our performance problem _is_, much less fixing it.  This session will cover common performance problems on iOS and Mac OS X, how to track down problems using tools such as Instruments, and ultimately, how to get the mindset to get your apps fast, and keep them there.

Even though the built-in Cocoa Touch controls are easy to use and powerful, they're kind of boring. Adding your own special sauce can make your app look cooler and make it easier to use. And it's easier than you think. This session shows you, step by step, the design and implementation of a custom user interface (http://borkware.com/hacks/keiser-keyboard.mov). Starting from a simple jpeg, using custom views with a bit of Core Graphics and Core Animation, along with a little Delegation, and ending up with a fun piece of UI.

.h files are everywhere. We create and edit them every day. Yet, they're something we tend not to think about very much. Over the years we've added layers of responsibility on these files, some of which make sense, and some that are misguided. Find out which is which in this meditation on interfaces.

Frameworks, algorithms, and design patterns are fun, and are very important tools for our day to day work. But there's a meatier, more human side to the whole programming business that often gets overlooked, and is rarely talked about : the attitudes and tools to build and maintain relationships amongst the humans, rather than the code.
