I bought the first Agile RoR book a couple years ago and went through
about half of it. I now have a project where I would like to try our
RoR again. But I don't know if my book is now out of date. I assume
Ruby has moved on since then, but not sure how much.
Can I get by using that original book? Or do I need to get it updated.
I have downloaded the free SitePoint book (waiting for the link) -
would that do as a replacement?
