Ruby Quiz Rails 3 tutorials, screencasts, talks, articles, blog posts & more. Michael Hartl Contents Foreword My former company (CD Baby) was one of the first to loudly switch to Ruby on Rails, and then even more loudly switch back to PHP (Google me to read about the drama). Though I’ve worked my way through many Rails books, this is the one that finally made me “get” it. The linear narrative is such a great format. Enjoy! Derek Sivers (sivers.org) Founder, CD Baby Acknowledgments The Ruby on Rails Tutorial owes a lot to my previous Rails book, RailsSpace, and hence to my coauthor Aurelius Prochazka. I’d like to acknowledge a long list of Rubyists who have taught and inspired me over the years: David Heinemeier Hansson, Yehuda Katz, Carl Lerche, Jeremy Kemper, Xavier Noria, Ryan Bates, Geoffrey Grosenbach, Peter Cooper, Matt Aimonetti, Gregg Pollack, Wayne E. About the author Michael Hartl is the author of the Ruby on Rails Tutorial, the leading introduction to web development with Ruby on Rails.

The Ruby Object Model - Structure and Semantics 2009-03-03 As part of my compiler project, one of my imminent decisions is what object model to use, and sine I like Ruby it seemed a good time to go through Ruby and look at the guts of the Ruby object model. If you've dabbled in meta-programming etc. for Ruby this post probably doesn't contain much new stuff for you. If you're a beginner you may want to look at a tutorial instead. If you're somewhere in between, hopefully there may be some insights here and there - especially if you're interested specifically in how things work "under the hood" rather than just what is visible to Ruby. The information in this post is based largely on the Ruby 1.8.x interpreter (you'll see it referred to as MRI as well - Matz Ruby interpreter - to distinguish it from other Ruby implementations), and we'll look at code fragments, as well as a diagram or two to illustrate.

Tuesday June 14, 2005 Sorry everyone for not blogging as much lately. It's just I've been having more fun with Ruby and Semantic Web stuff than anyone should legally be allowed to have. Today I made a conceptual breakthrough which is too exciting not to share right away. Right now I'm fleshing out the code and also making it a module instead of a Class. Why is this cool? A much better explanation of the concepts behind this snippet is forthcoming tonight, I promise!

Getting Started with Rails 1 Guide Assumptions This guide is designed for beginners who want to get started with a Rails application from scratch. It does not assume that you have any prior experience with Rails. Rails is a web application framework running on the Ruby programming language. Be aware that some resources, while still excellent, cover versions of Ruby as old as 1.6, and commonly 1.8, and will not include some syntax that you will see in day-to-day development with Rails. 2 What is Rails? Rails is a web application development framework written in the Ruby programming language. Rails is opinionated software. The Rails philosophy includes two major guiding principles: Don't Repeat Yourself: DRY is a principle of software development which states that "Every piece of knowledge must have a single, unambiguous, authoritative representation within a system." 3 Creating a New Rails Project The best way to read this guide is to follow it step by step. 3.1 Installing Rails Open up a command line prompt. 9 Security
The Bastards Book of Ruby Ruby in Twenty Minutes Introduction This is a small Ruby tutorial that should take no more than 20 minutes to complete. It makes the assumption that you already have Ruby installed. Interactive Ruby Ruby comes with a program that will show the results of any Ruby statements you feed it. Open up IRB (which stands for Interactive Ruby). If you’re using macOS open up Terminal and type irb, then hit enter. irb(main):001:0> Ok, so it’s open. Type this: "Hello World" irb(main):001:0> "Hello World" => "Hello World" Ruby Obeyed You! What just happened? irb(main):002:0> puts "Hello World" Hello World => nil puts is the basic command to print something out in Ruby. Your Free Calculator is Here Already, we have enough to use IRB as a basic calculator: irb(main):003:0> 3+2 => 5 Three plus two. irb(main):004:0> 3*2 => 6 Next, let’s try three squared: irb(main):005:0> 3**2 => 9 In Ruby ** is the way you say “to the power of”. irb(main):006:0> Math.sqrt(9) => 3.0 Ok, wait, what was that last one?
