Does anyone else consider this spam? Submitted by ossreleasefeed to ossreleasefeed.com, and is a question that could be very easily be asked as a self-referential submission here. There's no additional substance on the submitted site either-- seems to me like the author is simply trying to drive traffic to his/her site.
Yes. I wasted my time going to the link and trying to figure out if there were any answers to the posed question there and the only answers are in the comments here!
I learned Ruby by jumping into rails and building a small app. I learned how through various blogs, tutorials and railscasts. Then I later picked up Matz book and gained a deeper understanding of Ruby.
I've more recently begun to dig through the rails source to get a better understanding of what happening in the background and how certain things are achieved with pure Ruby.
I recommend just looking at the way others have used Ruby via various projects on github -- and then review the chapters in the pickaxe book to understand exactly how the syntax works.
I think the new O'Reilly book co-written by Matz is probably a great choice too, though I haven't read it yet.
