Books by David Thomas and Andrew Hunt

David Thomas and Andrew Hunt are American software engineers and early signatories of the Agile Manifesto. They have spent decades as consultants, educators, and writers in the software industry. Thomas co-founded the Pragmatic Bookshelf, a publisher focused on practitioner-oriented programming books. Hunt runs his own consultancy. Together they wrote The Pragmatic Programmer first in 1999, then substantially revised it for a 20th anniversary edition in 2019. The book's maxims — DRY, broken windows, tracer bullets — have passed into common use in the software industry.
