From Robert Brewer comes You are what you code, which has given me something to think about. I'll quote the opening:

Hey, you. Do you realize what you're writing? The long-standing IT joke is that you always end up coding your own job out of existence. But what are you coding yourself into?

(From Planet Python, where his blog is aggregated.)

Update: I apologize to my readers for putting a link here that doesn't work without an extra, annoying step (see the comment).

Update2: the situation has now been fixed.
