Book cover: Refactoring

What would you give to be able to improve your existing codebase with complete safety?

The Refactoring book completely changed the way I code.

In 2001 while searching for information on design patterns, I discovered the original wiki and stumbled onto Extreme Programming. This led me to a software development conference in 2002 called SD West. There I attended a session by Martin Fowler, and knew that I had to pick up his Refactoring book that day.

How could I resist a book that promised to teach me about “improving the design of existing code”?

Refactoring: Co-opted in the Workplace?

Many years later, I find the term “refactoring” being thrown around in the workplace, at company after company. Programmers and managers often talk about “refactoring,” when they mean “rewriting.” I’ve seen nightmares brought about by so-called “refactoring” that introduced so many defects, it compromised the product ship date.

Programmers talk about "refactoring," but they usually just mean "rewriting."

The Refactoring book, however, teaches a disciplined methodology of changing code in small steps, with automated verification of each step.

Of the books I have at work, I keep just a few within easy reach for looking things up. This is of those books. Each refactoring has a detailed recipe of its steps. Things usually go better when I open the book to follow those precise steps.

If my statement that it “completely changed the way I code” seems like hyperbole, another blogger states it even more strongly: “That moment changed my life.

Would you like to transform ugly code to make it better, but do so safely? What are you waiting for… buy a copy of the Refactoring book today!

About the author

Programming was fun when I was a kid. But working in Silicon Valley, I saw poor code lead to fear, with real human costs. Looking for ways to make my life better, I learned about Extreme Programming, including unit testing, test-driven development (TDD), and refactoring. Programming became fun again! I've now been doing TDD in Apple environments for 19 years. I'm committed to software crafting as a discipline, hoping we can all reach greater effectiveness and joy.

  • Hi,
    Finally received my copy of Refactoring. The hardcover somehow reminds me of the time I was in college.
    Enjoy the rest of the weekend.
    Best,
    -Herman
