Hans Reiser: "[...] [T]hose careful logs that seem so stupid and annoying in lab class, they are important in real life. You just can't remember benchmark configuration details 6 months or 3 years later, when you are wondering if there was maybe some other explanation of the data. It's even more important if you have a boss, because he needs to be able to make sense of the data, and summaries just don't do it when he is looking to provide an insight based on his experience."

No unprofiled code goes in: "Things that could not possibly affect performance, do, over and over again, and if you don't catch it immediately, you might never catch it."

On persistence and rigor: "I am not as qualified or clever as our competition, and we aren't as well funded, but we are much more persistent and rigorous. That is not what I wanted to believe would be my contribution to the field when I was a boy, but so it is. [...] A belief in data over consensus [is] what really matters."

"For an operating system, its expressive power is proportional to the number of allowed combinations of its components, not the number of components."
