I started learning ruby 3 months ago. I started with "Learn Ruby The Hard Way" that really holds your hand so that should help you with how to get started. Then I read the first 9 chapters of pickaxe. Then I did enough easy, medium and a few expert problems on codeeval.com to hit top 95% for ruby. Now I'm going through a few rails tutorials. Good luck.
Sounds like you want to grab the Pickaxe book. It's a tome, but it'll take you through the Ruby way of doing things. The Ruby Way is great and easily accessible, but I don't believe it's been updated for Ruby 2.0.
Lastly, you can always skim through the Ruby docs.
Edit: You should also check out POODR. Great way of learning how to refactor!
Eu prefiro um bom livro. Prefiro ter uma boa introdução de conceitos, complementada por exercícios. Se estivesse agora a começar a aprender começava por pyhton ou Ruby.
Para Ruby recomendo Programming Ruby 1.9 & 2.0: The Pragmatic Programmers' Guide (The Facets of Ruby).
Para Python nunca li nenhum, pelo que não sou o melhor para recomendar, mas uma pesquisa rápida revelou este: Python Programming for the Absolute Beginner, 3rd Edition que parece ser bem fixe.
Outra opção que acho bastante boa, é fazer um curso no Coursera, ou parecidos. Podes pegar num curso já concluído e avançar à velocidade que quiseres.
I realize this is something you probably don't want to hear, but you've got a way larger problem than the problem you posted about. If you're unable to figure out why you're getting an undefined method error from a really simple bit of Ruby code, then the actual problem is that you don't understand Ruby well enough yet. You should stop using Rails and first learn how to use Ruby properly. There are some excellent Ruby-only books, like the pickaxe book. And there are some great online courses as well. Once you can write non-Rails Ruby programs with ease, then you can start using Rails, and you'll find it'll be a thousand times easier.
I'd make sure I have a really solid understanding of systems and networks, e.g. how Linux works. This book seems like a great overview and I love No Starch Press. There's also this book which is used by Carnegie Mellon's introductory systems course, though that might be a bit too deep to dive into straight away, more like something that could be used if you want a deeper understanding of how systems work. You should have some familiarity with C just as foundational knowledge. The guy who wrote Learn Python The Hard Way also wrote an intro to C, Learn C the Hard Way. He's added a lot more material than the last time I checked (~Dec 2012) which looks like it covers a lot of topics so it would be great to work through it.
Some more technical books on this subject that are well regarded and can be used as reference books are Advanced Programming in the Unix Environment, Unix Network Programming, and The Linux Programming Interface
Also in addition to Python I'd also suggest learning some Ruby (Practical Object-Oriented Design in Ruby and Programming Ruby 1.9 & 2.0 are two resources I'd recommend), it's what Chef is/was implemented in and is fairly nice to work with.
> Which of the three will give the best chance to telecommute?
From my experience, as a general rule, I have found that anything related to web development is especially suited for telecommuting, so your choice would be Ruby on Rails. You can telecommute with roles like Sharepoint developers, DBA, sysadmin, but my impression is that most of these roles are in traditional big companies and they may not always be open to 100% telecommuting.
But be aware that by choosing a field that doesn't require your presence on-site, you're competing with developers from developing countries who will be able to outbid you.
> Which of the three is the least challenging to be learned on your own (and if you have any good learning resources you can recommend, I'll take them all, thanks)?
I think all are equally challenging if your aim is to be really good in that field and difficulty is a subjective notion anyway.
As for resources: when I was dabbling in Ruby on Rails a few years ago, I found this tutorial very useful: Ruby on Rails Tutorial
You also need a good understanding of the Ruby programming language. I recommend Programming Ruby, though I liked The Ruby Programming Language because it was a lot more concise (if dated). You can ask /r/ruby for more suggestions.
