"I used to , for Plan 9. They were always ahead of us—they just had massively more resources to deal with hardware. So when we'd run across a piece of hardware, I'd look at the Linux drivers for it and write Plan 9 drivers for it. Now I have no reason to look at it. I run Linux. And I occasionally look at code, but rarely, so I can't really tell whether the quality has gotten better or not . But certainly the reliability has gotten better."

“I do believe that in a race, it is naive to think Linux has a hope of making a dent against Microsoft starting from way behind with a fraction of the resources and amateur labor.”

“We have persistent objects, they're called files.”

“If you want to go somewhere, goto is the best way to get there.”

“I think the major good idea in Unix was its clean and simple interface: open, close, read, and write.”

“Unix was built for me. I didn't build it as an operating system for other people, I built it to do games, and to do my stuff. I was always into games, games was my thing. I used to play pinball machines, and I would pick the lock in the back of pinball machines. Then I'd study the diagrams that I had. That's where I learned a lot of this kind of logic.”

“In Plan 9 and Inferno, the key ideas are the protocol for communicating between components and the simplification and extension of particular concepts. In Plan 9, the key abstraction is the file system—anything you can read and write and select by names in a hierarchy—and the protocol exports that abstraction to remote channels to enable distribution. Inferno works similarly, but it has a layer of language interaction above it through the Limbo language interface—which is like Java, but cleaner I think.”
