Lakos'20: The "Dam" Book is Done!
summary
Announces Large-Scale C++ — Volume I and argues that investing in hierarchical, reusable libraries—Software Capital—lets teams get faster, better and cheaper simultaneously at enterprise scale. Shows concrete C++03 code patterns (header/implementation/test component layout, iterators, abstract interfaces, allocator/memory_resource) and builds a real calculate_optimal_partition utility: initial exponential solver, then memoization, reference-based solution nodes and a triangular packed cache. Empirical reuse numbers: size‑5 ≈81.48% reuse, size‑10 ≈99.72% reuse; the optimized implementation scales and reduces rebuild/link costs.
