"I think one of the interesting things about the Linux phenomenon is that has been able to keep some kind of control over such an amazingly extended development environment. I’m certainly glad that I didn’t have to develop C in public, because you get more suggestions than you really want. Being in this nice, small group, you can control that sort of thing. I honestly don’t know the dynamics and the details of the Linux kernel project. However, one of the knocks on Linux is that it is undisciplined. But I think probably the fairer observation is that it is amazingly disciplined, compared to what you would expect, given the nature of the endeavor."

“I think the Linux phenomenon is quite delightful, because it draws so strongly on the basis that Unix provided. Linux seems to be the among the healthiest of the direct Unix derivatives, though there are also the various BSD systems as well as the more official offerings from the workstation and mainframe manufacturers.”

“I don’t really distinguish between Linux and things that are more or less direct descendants of Unix. I think they’re all the same at some level. Often, people ask me, "Do you feel jealous about Linux being the big thing." And the answer is no, for the same reason. I think they’re the same.”

“the power of assembly language and the convenience of … assembly language.”

“C is quirky, flawed, and an enormous success.”

“Another danger is that commercial pressures of one sort or another will divert the attention of the best thinkers from real innovation to exploitation of the current fad, from prospecting to mining a known lode.”

“The working examples of important new systems seem to have come either from entrepreneurial efforts or from large companies, like Bell Labs and most especially Xerox, that were much involved with computers and could afford research into them, but did not regard them as their primary business.”
