In many cases the user interface to a program is the most important part for a commercial company: whether the programs works correctly or not seems to be secondary.

Bad programmers worry about the code. Good programmers worry about data structures and their relationships.

Nobody actually creates perfect code the first time around, except me. But there's only one of me.

While we ended up having several core maintainers use BitKeeper - it was free to use for open source projects - it never got ubiquitous. So it helped kernel development, but there were still pain points.

That's what makes Linux so good: you put in something, and that effort multiplies. It's a positive feedback cycle.

In open source, we feel strongly that to really do something well, you have to get a lot of people involved.

I have an ego the size of a small planet.
