Collection of essays on software engineering

If you haven't already read Joel Spolsky's books on software (Joel on Software and Best Software Writing), I'd highly recommend them.  But while those are geared towards working on large projects at big companies, "Getting Real" from 37 Signals is a collection of essays about software engineering at a startup (and most of the lessons apply even if you are a team of one).  Better yet, it's free, so what have you got to lose?
