I read the Unix source code a while back (Lyon’s) and it seems to me that all of personal computing is the extrapolation of three structs: u…

This post discusses how fundamental data structures in early Unix—specifically three key structs from John Lions' Unix source code commentary—served as the conceptual foundation for the evolution of personal computing. The author argues that much of modern computing architecture and design can be traced back to these core structural patterns established in Unix's foundational code.
