Why Programs Fail: A Guide to Systematic Debugging

21st
JUN

This book can teach you how to debug more effectively. It is a complete and pragmatic overview of debugging, written by a talented researcher who has developed many clever ways to isolate bugs. It explains best practices for finding and fixing errors in programs, ranging from systematically tracking error reports, reproducing failures, observing symptoms, isolating the cause, and correcting defects. Along with basic techniques and commonly used tools, the book also explores the author’s innovative techniques for isolating minimal input to reproduce an error and for tracking cause and effect through a program.

Studying this book will make you a better programmer. You will be able to find and fix errors in your code (and your colleague’s code) faster and more effectively, a valuable skill that will enable you to finish projects earlier and produce programs with fewer defects. Also, if you read between the lines you will learn how to write code that is more easily tested and debugged, which further increases your ability to find and correct defects. And thinking hard about what can go wrong with your program can help you avoid mistakes in the first place, so you have less to debug.
