What hackers pick instead

• Designing Data-Intensive Applications by Martin KleppmannWidely recommended guide to distributed systems, databases and data-intensive design, valued for depth, structure and topics that stay relevant.37recommend
• A Philosophy of Software Design by John OusterhoutShort, practical book on software design that people say improves code and team habits. One critic says it reads more as a set of heuristics than a rulebook.28recommend
• Code Complete by Steve McConnellRecommended for practical, research-backed advice on software construction and managing codebase complexity, and remains a favorite for many readers.14recommend
• The Architecture of Open Source Applications by Amy Brown and Greg WilsonLearn software architecture by example: each chapter is written by a maintainer of a real open source project, showing how to think about application design.13recommend
• Design Patterns by Gamma, Helm, Johnson and VlissidesRecommended for teaching reusable object-oriented design vocabulary and solving code design problems. Critics say some patterns are dated, tied to C++/Java as of 1994, or overused.12recommend
