This is how a programmer I deeply respect described her more aggressive years. (Piss and vinegar)

She attributed the same notion to a young programmer I hope will be able to make an impact on other coders.

Sounds like it might (piss and vinegar) might contribute to people hackin' stuff out that hadn't been tackled before.

I got pissed at Emacs the other day and solved a problem that had been bugging me, for example.
