I’ve put the slides online for my Boston Ruby Group talk “Babies vs. Zombies”. In the talk I mentioned the excellent paper Big Ball of Mud and the fascinating study “How Many Variables Can Humans Process?”. http://www.youtube.com/watch?v=4ocIjpAxfXE

Are you a good Ruby on Rails developer that loves to code? Have you published a high-quality, successful gem? If not, you may be making a mistake that could cost you as much as $100,000. If this surprises you, there are three things you should realize: Fact #1: If you can create a high-quality, successful […]
The Wicked Good Ruby Conf got off to a great start today with a powerful singing performance by Liana Leahy and a wonderfully inspiring and sobering keynote by Sandi Metz. After the keynote, I attended the talk Wicked Bad Ruby by Matt Aimonetti and it really struck a chord with me. The discussion afterwards with […]
The tabulous gem has continued to grow in popularity ever since I released it in 2011. Since so many people have found it useful, I decided to give it some love. Tabulous 2 is a complete rewrite, featuring a simpler syntax and new behavior. Tabulous is designed to be perfect for quick prototyping, robust enough […]
Have you ever hesitated when trying to refactor a controller for simplicity? Sure, you know how to write a controller so that it “works”. You even know how to organize your controllers in a resource-oriented, RESTful way. But when it comes to understanding the purpose of controllers, they’ve always seemed a bit fuzzy. And they’ve […]
If you followed my advice in the previous post, your Gemfile would look something like this:
source :rubygems gem 'rails', '3.0.3' gem 'devise', '1.1.5' gem 'redgreen', '1.2.2' gem 'capybara', '0.4.0'

If the Ruby code you write never leaves your computer, then this article is not for you. But if you find yourself sharing Ruby code with others, or deploying your Ruby code to a web server, then you have a problem. And that problem is gem versions. Sooner or later, the version of a gem on your computer will not match the version of that gem on your production web server, and your cute little disruptive social media web app will fail in a steaming pile of 500 errors.
This tutorial shows you how to make a simple Rails application from scratch that has both tabs and subtabs.
If you’re like me, most of the Rails applications you’ve written use tabbed navigation. And if you’re like me, you find that writing the code to handle tabs becomes increasingly more boring with each new application. So I wrote tabulous. Tabulous aims to solve this problem once and for all with a quick and easy way to set up and manage your tabs.
