You know, the mark of intelligence is realizing when you're making the same mistake over and over and over again, and not hitting your head in the wall five hundred times before you understand that it's not a clever thing to do.

I think one thing I do pretty well is not taking myself too seriously.

If you have ever done any security work - and it did not involve the concept of "network of trust" - it wasn't security work, it was - masturbation. I don't know what you were doing. But trust me, it's the only way you can do security, it's the only way you can do development.

I started Linux as a desktop operating system. And it's the only area where Linux hasn't completely taken over. That just annoys the hell out of me.

When you say 'I wrote a program that crashed Windows,' people just stare at you blankly and say 'Hey, I got those with the system, for free.'

Eventually the revolutionaries become the established culture, and then what will they do

In my opinion MS is a lot better at making money than it is at making good operating systems.
