The Pragmatic Programmer

A craft manual for software as a discipline. Hunt and Thomas codify decades of tacit knowledge about how working programmers actually build things well: broken windows, tracer bullets, orthogonality, the discipline of DRY. The book insists that software has texture — entropy accumulates, the wrong abstraction costs, and tools are never neutral. Anyone directing a product without this material tends to mistake planning for building. Reading it does not turn you into a programmer; it makes the programmers' choices legible to you, and half of product direction happens in that conversation.
