OK, so the paper version of Eloquent Ruby is off to production. That means it's a couple of months away from making an appearance. It also means I'm done, with a capital "Ahhh." pragprog.com/titles/eruby...
Eloquent Ruby, Second Edition
Write elegant Ruby code--not just correct, but idiomatic. Go beyond the vocabulary and syntax and learn to express yourself with eloquence.
