The Right Way to Code DCI in Ruby :: Mike Pack Development
Note: This website has been deprecated and is no longer maintained. Many articles found in the Ruby community largely oversimplify the use of DCI. These articles, including my own, highlight how DCI injects Roles into objects at runtime, the essence of the DCI architecture. Many posts regard DCI in the following way: class User; end # Data module Runner # Role def run ... end end user = User.new #
Dotan Nahum - Pragmatic Concurrency With Ruby
@jondot | CTO at Como. Hacker. Fullstacker. Big data. Open sourcer. I'm coming from a parallel computation, distributed systems background by education, and have relatively strong foundations in infrastructural concurrent/parallel libraries and products that I've built and maintained over the years both on the JVM and .Net. Recently, I've dedicated more and more time building and deploying real co

Let’s define a class with all three: class Heart def public_method; end
Ruby Tidbit: __LINE__ and heredocs
You’re probably familiar with LINE keyword in Ruby. Wherever it’s used, it refers to the line number in the current file. It says so right here in the Ruby docs. QUICK! What’s the output of the following code? #!/usr/bin/env ruby class LineDemo def self.process(text, lineno) # do important processing on text puts lineno end end LineDemo.process <<TEXT, __LINE__ Here is some text on which we will d
Redirector: A Redirect Rule Engine for Rails Applications | Viget
Something we get asked to do again and again on projects is to add redirects for either old URLs (from legacy systems) or custom URLs for marketing campaigns. We often start with Rack::Rewrite, but often times we find ourselves in a situation where it would be better for the client to manage these redirect rules. We did it enough times that it seemed like we should stop rebuilding the same thing o
