Crockford: One of the things I’ve been pushing is code reading. I think that is the most useful thing that a community of programmers can do for each other—spend time on a regular basis reading each other’s code. There’s a tendency in project management just to let the programmers go off independently and then we have the big merge and if it builds then we ship it and we’re done and we forget about it.

One of the consequences of that is that if you have weak or confused programmers you’re not aware of their actual situation until much too late. And so the risks to the project, that you’re going to have to build with stuff that’s bad and the delays that that causes, that’s unacceptable. The other thing is that you may have brilliant programmers on the project who are not adequately mentoring the other people on the team. Code reading solves both of those problems.

Seibel: Can you talk a bit about how you conduct a code reading?

Crockford: At each meeting, someone’s responsible for reading their code,
