Why I recommend this book:

This book has aged beautifully because it focuses on principles, not technologies. The DRY principle, orthogonality, and the pragmatic philosophy of “think about your work” are as relevant today as when it was first published in 1999. I particularly value the sections on professional development—how to communicate effectively, manage projects responsibly, and continuously invest in your knowledge portfolio. The 2019 update adds modern context while preserving the timeless wisdom. Every developer should read this at least once.
