Something I said today that I really believe:
The problem with hacks and kludges isn't that they're quick and dirty. The problem is that people so often forget the two big things: What is or isn't a kludge, and when a kludge is appropriate.
(hint: skating the deadline for a one-off demonstration might be a good time for a hack. Provided that your spit and bailing wire solution holds long enough to do the job. But don't pretend it's a permanent fix or a substitute for really knowing where the gaps are.)
