So since these changes have been made, will us noobs be hurting ourselves
starting off learning 1.8.6? Books to learn from are teaching from 1.8.
I think things are looking up for Ruby 1.9 books, actually. Here’s
the path I’d recommend (with some obvious bias)
= To grasp the fundamentals
“The Well Grounded Rubyist” 
= To understand the details
“Programming Ruby 1.9”  and/or “The Ruby P.ming Language” 
= To use Ruby effectively
“Ruby Best Practices” 
This will give you a very well rounded experience, and once you
understand Ruby 1.9, quite a bit of your knowledge will still transfer
smoothly back to 1.8.
Most of these books are in Beta right now, all except , but if you
pick them up know you will help us catch problems before we go to
print, improving the situation for those taking the plunge directly
into Ruby 1.9.
