User Review - mykl-s - LibraryThing-helped make me a good programmer -It 's about simplicity and clarity and about designing first, then writing -not an easy read, but well worth it Read full review

#### LibraryThing Review

User Review - MarkvanderPol - LibraryThingOne of the grandfathers of computer science. Lucid exploration of fundamental programming constructs that are still the daily tools of legions of programmers worldwide. If only they had the concept grounding from this book (or those like it) myriads of bugs would never be written. Read full review
