No code runs faster than no code.
No code has fewer bugs than no code.
No code uses less memory than no code.
No code is easier to understand than no code.
No code is the best way to have secure and reliable applications. Write nothing; deploy nowhere.
One of my most productive days was throwing away 1,000 lines of code. -- Ken Thompson
The cheapest, fastest, and most reliable components are those that aren’t there. -- Gordon Bell
Deleted code is debugged code. -- Jeff Sickel
Master Foo and the Ten Thousand Lines
Master Foo once said to a visiting programmer: “There is more Unix-nature in one line of shell script than there is in ten thousand lines of C.”
The programmer, who was very proud of his mastery of C, said: “How can this be? C is the language in which the very kernel of Unix is implemented!”
Master Foo replied: “That is so. Nevertheless, there is more Unix-nature in one line of shell script than there is in ten thousand lines of C.”
The programmer grew distressed. “But through the C language we experience the enlightenment of the Patriarch Ritchie! We become as one with the operating system and the machine, reaping matchless performance!”
Master Foo replied: “All that you say is true. But there is still more Unix-nature in one line of shell script than there is in ten thousand lines of C.”
The programmer scoffed at Master Foo and rose to depart. But Master Foo nodded to his student Nubi, who wrote a line of shell script on a nearby whiteboard, and said: “Master programmer, consider this pipeline. Implemented in pure C, would it not span ten thousand lines?”
The programmer muttered through his beard, contemplating what Nubi had written. Finally he agreed that it was so.
“And how many hours would you require to implement and debug that C program?” asked Nubi.
“Many,” admitted the visiting programmer. “But only a fool would spend the time to do that when so many more worthy tasks await him.”
“And who better understands the Unix-nature?” Master Foo asked. “Is it he who writes the ten thousand lines, or he who, perceiving the emptiness of the task, gains merit by not coding?”
Upon hearing this, the programmer was enlightened.
