When teaching a rapidly changing technology, perspective is more important than content.

The discipline of programming is most like sorcery. Both use precise language to instruct inanimate objects to do our bidding. Small mistakes in programs or spells can lead to completely unforseen behavior: e.g., see the story, "The Sorcerer's Apprentice". Neither study is easy: "...her [Galinda's] early appetite for sorcery had waned once she'd heard what a grind it was to learn spells and, worse, to understand them." from the book "Wicked" by G. Maguire.

The three most important aspects of debugging and real estate are the same: Location, Location, and Location.

A class, in Java, is where we teach objects how to behave.

Code should run as fast as necessary, but no faster; something important is always traded away to increase speed.

When debugging, novices insert corrective code; experts remove defective code.
