About the Book

"The ability to debug code is arguably more important than the ability to write code."

I've been helping people debug Ruby code for years now in the #rubyonrails IRC channel on Freenode, Stack Overflow and as a full-time job.

Debugging Ruby is a book containing examples of common debugging pitfalls with Ruby code and Rails applications, using cases that I've seen in my day-to-day work. Starting off with some simple Ruby examples and moving into more and more complex territory, this book will educate you in the ways of debugging Ruby code efficiently and what to do in the case of when things go wrong.
