Chapter 15. Debugging

In this chapter, we dig deeply into what is involved in debugging problems. In Chapter 14, we put debugging into the larger context of customer care. This chapter, on the other hand, is about you and what you do when faced with a single technical problem.

Debugging is not simply making a change that fixes a problem. That’s the easy part. Debugging begins by understanding the problem, finding its cause, and then making the change that makes the problem disappear for good. Temporary or superficial fixes, such as rebooting, that do not fix the cause of the problem only guarantee more work for you in the future. We continue that theme in Chapter 16.
