Ruby 4 Rails

About this presentation

FRIEND: Hey Simone, I want to start learning Rails.

ME: Really?

FRIEND: You know, I have been working in PHP and Symfony for a while and now I want to try something new.

ME: That's cool.

FRIEND: Could you help me studying Rails?

ME: Sure. But if you really want to learn Rails, you need to start from Ruby.

FRIEND: I worked with PHP and several other languages. Is Ruby really that difficult?

ME: Learning the Ruby syntax is not that difficult. Thinking like a Rubyist is the real challenge. If you really want to appreciate Ruby, you must understand the Ruby ecosystem and the philosophy behind the language.

FRIEND: Ok. Could you teach me that?

ME: I can start giving you some directions, then you'll have to start working on it.

ME: I'm going to prepare a brief introduction to Ruby. I'll try to extract the most important features of the language, keeping an eye on Rails since that is your ultimate goal.

FRIEND: Cool. How long it will take.

ME: Let's schedule one full day. I'll show you the presentation and we'll start digging into Ruby. At the end, we'll try to summarize everything by giving a look at Rack and creating a small MVC application using the awesome Sinatra framework. It is not Rails, but it's definitely a good starting point. We can't concentrate too much concepts into a single session.

FRIEND: I agree.

FRIEND: See you on Saturday, I can't wait to start playing with Ruby.

This is that presentation. Enjoy Ruby!
