View source for Douglas McIlroy

'''Douglas McIlroy''' is a mathematician, engineer, and programmer best known as the creator of the Unix pipeline concept and the original developer of the Unix diff, spell, and macro processors. With [[Jon Bentley]], he developed the three-way partitioning scheme for [[Quicksort]] that made the algorithm robust against duplicate keys. McIlroy's intellectual style — combining formal rigor with practical systems engineering — exemplifies the Unix philosophy that small, composable tools are more powerful than monolithic applications. His work on [[Pipes and Filters|pipes and filters]] introduced a programming paradigm in which the output of one process becomes the input of another, enabling the construction of complex workflows from simple components.
