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.

ZetCode, tutorials for programmers 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
Ruby Primer - Introduction to Objects We will begin our journey with objects. In Ruby, just like in real life, our world is filled with objects. Everything is an object - integers, characters, text, arrays - everything. To make things happen using Ruby, one always puts oneself in the place of an object and then has conversations with other objects, telling them to do stuff. Roleplaying as an object in your program is an integral part of object-oriented programming. Try it for yourself: As you can see, if you don't specify which object you are, you automatically play the role of the main object that Ruby provides us by default. We'll delve into how one can play the role of different objects and why this is useful a little further down the line.
Ruby/DBI Tutorial y printer This session will teach you how to access a database using Ruby. The Ruby DBI module provides a database-independent interface for Ruby scripts similar to that of the Perl DBI module. DBI stands for Database independent interface for Ruby which means DBI provides an abstraction layer between the Ruby code and the underlying database, allowing you to switch database implementations really easily. DBI can interface with the following: ADO (ActiveX Data Objects)DB2FrontbasemSQLMySQLODBCOracleOCI8 (Oracle)PostgreSQLProxy/ServerSQLiteSQLRelay Architecture of a DBI Application DBI is independent of any database available in backend. The general architecture for Ruby DBI uses two layers: The database interface (DBI) layer. Prerequisites: If you want to write Ruby scripts to access MySQL databases, you'll need to have the Ruby MySQL module installed. This module acts as a DBD as explained above and can be downloaded from Obtaining and Installing Ruby/DBI: Step 1 Step 2
OkayFreedom VPN. A simple VPN service enabling private, uncensored web surfing. Learnable Ruby Tutorial Como lenguaje multiplataforma, Ruby ha sido portado a distintos sistemas operativos y arquitecturas. Esto significa que si tu desarrollas un programa en un PC (por ejemplo), será posible ejecutarlo en otra máquina distinta como es un MAC (por poner otro ejemplo). Las siguientes instrucciones son para instalar Ruby en un PC. Para otras plataformas, ver este capítulo de la *Why's (poignante) guide to ruby*. La forma más sencilla de instalar Ruby en un PC es mediante el Ruby One-Click Installer. La instalación de Ruby incluye la primera edición del libro "Programming Ruby" y el editor SciTe. Supongamos que la instalación de Ruby fue en c:/ruby. c:/ruby/bin es donde los ejecutables son instalados (incluyendo ruby e irb).c:/ruby/lib/ruby/1.8 aquí están programas escritos en ruby.
