Lessons from Dennis Ritchie: The Birth of UNIX and the Power of Sharing

We all know Dennis Ritchie, the father of UNIX and the C language, who passed away last week; his influence on computer science is comparable to that of Alan Turing and, controversially, Steve Jobs.

UNIX began when Ken Thompson created a game called Space Travel that ran slowly and cost $75 on the MULTICS system, prompting Ritchie and Thompson to build a cheaper, shareable environment for hobbyists, embodying the principle of "sharing".

First lesson: be interested in what you do. Their initial goal was not profit but saving money and making their game run on a less expensive machine.

Second lesson: step out of your comfort zone. Although Ritchie was trained in physics and mathematics, he became a legendary programmer, showing that venturing into unfamiliar fields can lead to breakthroughs like UNIX and C.

Third lesson: cultivate innovative thinking. Working at Bell Labs with ample funding and staff gave Ritchie the freedom to pursue his ideas on his own schedule.

Final lesson: understand the value of sharing. Many modern companies hide core technologies, but the open nature of UNIX demonstrates that openness, rather than secrecy, drives success.

Today, UNIX remains one of the most important software platforms because it is open to anyone, disproving the notion that openness cannot be profitable.

Ritchie also taught us that the computer world is not an impenetrable mystery; even if we never match his achievements, we can still build valuable innovations on top of UNIX's source code.

The article concludes with a metaphor about chess programs becoming smaller at the cost of rules, suggesting that continual optimization and creativity will keep the competition alive.
