An excerpt from “The Rails Way”:
An average developer might see his productivity double with Rails, but I’ve seen serious
Rails developers achieve gains that are much, much higher. That’s because we follow the Don’t
Repeat Yourself (DRY) principle religiously, of which Don’t Reinvent The Wheel (DRTW) is
a close corollary. Reimplementing something when an existing implementation is good
enough is an unnecessary waste of time that nevertheless can be very tempting, since it’s such
a joy to program in Ruby.
Yup, this is my kind of gig!
