A rational model of software is to design it quickly - the economic pressure to improvise presents an interesting challenge.

One of the advantages of having to live with JUnit for 8 years is now we can look back and see which decisions we made worked nicely and which we would have done differently.

There are musicians who want to make a living making music. There are listeners who want to listen to music.

Studios are so used to digital now, and there is a mythology that it's cheaper. But it's really not cheaper. For instance, digital is great for night exteriors; everybody knows it's a video tap, so it's very responsive to light.

I don't think the Internet is necessarily a dangerous place. It's only dangerous if you don't make people earn your trust. You can't take people at their word.
