This interests only a tiny group of people so I've decided to post in the forums instead, as it's unlikely to get more than a couple of votes.
If you program in Ruby or RoR, the latest edition of the Pickaxe book updated for Ruby 1.9.2, from Pragmatic Programmers Press is for sale at $10 US for a limited time for the 10th anniversary printing.

I bought an e-book version using Paypal and it came up to about $10.30 AUD after exchange.
Thanks. Would you suggest this book if someone is thinking of picking up Ruby?
