It’s going to be just a quick post before I get into some practical details about today’s learning. I want to recommend you this book I’m working with at the moment. Actually I have started learning Ruby with this book as based on my readings this is an ideal book for someone who is new to programming not just to the Ruby language. Chris Pine’s Learn to Program book teaches you the Ruby language while introducing you to the core concepts and rules of programming. It has a very easy and understandable approach and plenty of practical examples to get your head around the new things. Do not hesitate to buy it. You can get it from Amazon or from the Pragmatic Bookshelf if you want it on your Kindle instead of your bookshelf.
I was thinking about buying it but i am not sure it is not outdated, since it was released in 2009.
Based on what I have learnt so far from the book I think it is not outdated. It teaches basic concepts which usually do not change. If you are new to programming it definitely worth it. If you already know how to program even on a different language probably this is too low-entry for you.
