Eloquent Ruby (Addison-Wesley Professional Ruby Series)

Do you know why experienced Ruby programmers tend to reach for basic collections and hashes while programmers from other languages go for more specialized classes? Do you know the difference between strip, chop, and chomp, and why there are three such similar methods when apparently one might suffice? (Not to mention lstrip and rstrip!) Do you know the downsides of dynamic typing? Do you know why the differences between strings and symbols get so blurry, even to experienced Ruby developers? How about metaprogramming? What the heck is an eigenclass? How about protected methods? Do you know what they’re really about? Really? Are you sure?

Russ knows all that stuff and more. And if books are like babies, then Russ is that experienced mom who pops out her second child after a couple of hours of labor and is back at work a week later in her pre-pregnancy clothes as if nothing out of the ordinary happened. You know: the one all the other moms talk about in hushed tones of disbelief and reverence. That’s the way my series authors discuss Russ.

Not that there’s anything small or insignificant about Russ’ bouncing new baby . . . eh, I mean book. On the contrary, weighing in at just over 400 pages, this tome is slightly larger than its older sibling Design Patterns in Ruby. The family resemblance is crystal clear: Russ is first and foremost your friend. His approachable writing style makes even the driest Ruby language topics engaging and funny. Like the way that symbols remind Russ “of the eyes peering out from the tilted head of a confused but friendly dog.”
