Sorry for popping in like this with a commercial, but I've been busy
trying to finish this project up.
I just finished up my Ruby book, which is the first of two volumes
that will eventually grow into my Ruby/Rails book. It's a short (144
pages in all), learning Ruby book that walks you through the steps to
learn Ruby from the basics to using XML-RPC and more.
It's available in print for $10 (I know, I know...I said $9
originally...but printing is expensive!) and eBook for $5.
