Live free or die talks about the development history of the UNIX trademark. The translation either lives wonderfully or dies happily.

In the 1960s, AT & T's laboratory Ken Thompson began early research and development to create a simple and replicable UNIX operating system. At that time, computers were as big as a house, living in 32K of memory and disk. Later it developed to AT & T. In order to maintain the competitive barriers of enterprises and suppress competitors, bureaucracy suppressed the openness of open source. After the low-price sale, commercialization moved to two levels. SUN, HP, and IBM all customized their own Unix-like systems. Microsoft also built its own software empire through bidding. Today's Apple has developed into its own closed ecosystem from this; Linux has also been squeezed by Microsoft's operating system in the evolution of open source until today's open development of the Internet; Google's operating system has once again fully demonstrated its unique advantages from Microsoft's operating system.
