Lakos’20: The “Dam” Book is Done!
summary
After twenty years of practice the book claims a concrete method for creating Large-Scale C++ Volume I that makes software reuse scalable: design physical hierarchies of .h/.cpp components, enforce hierarchical reuse and stability for vocabulary types, and ship component-level test drivers and contracts. A worked example translates exponential recursive layout into a memoized solution cache stored in a preallocated triangular packed array, showing dramatically reduced work and real-world savings that cross a multi-year break-even and let HTTP versions coexist without breaking clients.
