The Pragmatic Programmer

The Pragmatic Programmer by David Thomas and Andrew Hunt, originally published in 1999 and updated in a 20th anniversary edition in 2019, is one of the most influential books ever written about software development. Rather than focusing on a single technology, the book deals with the meta-skills and attitudes that make a great programmer: avoiding duplication through the DRY (Don’t Repeat Yourself) principle, writing orthogonal code, using power tools effectively, and testing relentlessly. The authors introduce memorable concepts broken windows theory, tracer bullets, rubber duck debugging that have become part of the shared vocabulary of software developers worldwide. Essential reading for anyone at any stage of a software career who wants to grow into a thoughtful, effective, professional programmer.
