Objects on Rails Learn Web Development with the Ruby on Rails Tutorial My Book Scanner See Android Book Scanner for the successor to this never completed project. Introduction A Saturday afternoon in January was aproaching the time of twilight, and that vast tract of unenclosed wild known as the Internet would soon suck me into the geekest project yet in my collection of geeky projects. (See for instance the Mark II Cell Phone Ring Detector.) This was the last weekend in January of 2011 and I stumbled across the DIY Book Scanning web site. It was like finding the Holy Grail! Eagerly perusing the forums, I soon started making plans for my own scanner and discovering just how disorganized the forums are :-). Cameras The first thing I'd need would be a pair of cameras. Camera Trigger Before building any physical infrastructure, I figured I should make sure the cameras could be triggered correctly. Once I got everything wired up, it seems like all three switches work fine. Now all I need is to test with the cameras. Base Platform Platen Interlude With Cameras More Platen Lights Wiring
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?

Learn Web Development with the Ruby on Rails Tutorial 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.
