Famous Doug McIlroy Quotes

“It's proof that open-source can breed monsters just like the commercial pros.”

Doug McIlroy (2013). In their own words: Unix pioneers remember the good times http://www.networkworld.com/article/2168942/servers/in-their-own-words--unix-pioneers-remember-the-good-times.html
Context: I don't know the counts of Unix and Linux servers. I do know that my heart sinks whenever I look under the hood in Linux. It is has been so overfed by loving hands. Over 240 system calls! Gigabytes of source! A C compiler with a 250-page user manual (not counting the language definition)! A simple page turner, 'less,' has over 40 options and 60 commands! It's proof that open-source can breed monsters just like the commercial pros. Miraculously, though, this monster works.

“Everything was small… and my heart sinks for Linux when I see the size of it.”

Doug McIlroy (2005). Ancestry of Linux — How the Fun Began https://archive.org/details/DougMcIlroy_AncestryOfLinux_DLSLUG
Context: Everything was small... and my heart sinks for Linux when I see the size of it. [... ] The manual page, which really used to be a manual page, is now a small volume, with a thousand options... We used to sit around in the Unix Room saying, 'What can we throw out? Why is there this option?' It's often because there is some deficiency in the basic design — you didn't really hit the right design point. Instead of adding an option, think about what was forcing you to add that option.

“The notion of "intricate and beautiful complexities" is almost an oxymoron. Unix programmers vie with each other for "simple and beautiful" honors — a point that's implicit in these rules, but is well worth making overt.”

Doug McIlroy (2003). The Art of Unix Programming: Basics of the Unix Philosophy http://www.catb.org/esr/writings/taoup/html/ch01s06.html

“This is the Unix philosophy: Write programs that do one thing and do it well. Write programs to work together. Write programs to handle text streams, because that is a universal interface.”

Doug McIlroy (2003). The Art of Unix Programming: Basics of the Unix Philosophy http://www.catb.org/esr/writings/taoup/html/ch01s06.html
