  Static Code Analysis

The most important thing I have done as a programmer in recent years is to aggressively pursue static code analysis.  Even more valuable than the hundreds of serious bugs I have prevented with it is the change in mindset about the way I view software reliability and code quality.It is important to say right up front that quality isn’t everything, and acknowledging it isn’t some sort of moral failing.  Value is what you are trying to produce, and quality is only one a...

It's actually very easy.Now, I am not building Mail, Angry Birds or Photosynth or anything, but the core concepts of the SDK are not that bad once you spend some time learning delegation.
