A few months ago, I was inspired by this post on Reddit, titled: Food items should have QR codes that instruct the microwave exactly what to do. Like high for 2 minutes, let stand 1 minute, medium 1 minutes.. I thought this was a pretty cool idea, and that it

Whenever I'm looking at backtraces, logs, or failing tests in the terminal, I often need to open one of those files in my text editor. It was previously a semi-arduous process that involved highlighting, copying, pasting and the return key. Now, all I need to do is double-click

Note: This post is for people who use the terminal to run Rails generators. It probably won't interest you if your editor has a plugin to run them. After running a Rails generator, you'll often need to edit the generated files in your text editor. Rails

Every Rails developer has probably seen the following error: Could not find <gem> in any of the sources Run `bundle install` to install missing gems. This happens if you or someone else adds a gem to your Gemfile, or if a gem version is updated in Gemfile.lock,

capistrano_colors has been merged into capistrano. If you update capistrano to version 2.13.5, you will no longer need to include capistrano_colors in your Gemfile. Don't forget to also remove require 'capistrano_colors' from config/deploy.rb. If you've been using

A day in the life of a Rails developer will usually involve a few git pulls, bundle installs, and switching between different projects. I thought it would be great if my projects could be automatically kept up-to-date, so that I don't have to spend too much time updating

I'm currently doing a lot of work on an open source Ruby on Rails project called Fat Free CRM. The code is hosted on github, and we are using the amazing continuous integration service provided by Travis CI. Find out more about Travis CI here. We've

I use gedit to write code. I keep a filebrowser tab open at the left side of my screen, and sometimes I need to look at gem's source code. RVM is awesome, and it keeps my 1.8.7 gems, 1.9.2 gems and all my gemsets

I've written a tiny web application called 'Avatar Harmony'. You can sign in with twitter or facebook, add your Gravatar login details, and the app will automatically sync your profile pics across each of your accounts. It can sync avatars in the following directions: * Facebook =>

Capistrano is a great tool, and I couldn't imagine running a project without it. I always wanted a quick way to know exactly what was running on each of our servers, and needed to know what would would change when I ran 'cap deploy'. "cap

When you run a rake task for a Rails 3 project, it has to load the entire environment since gems can include their own rake tasks. I started to get annoyed by this, because every capistrano deployment would load up rails on my environment just to notify hoptoad. If you

We are working with a Rails 3 port of Fat Free CRM. We have so many plugins modifying classes that we have to set config.cache_classes to true. But all our view templates seemed to stay cached as well, and I had to restart the server each time I

Building a ruby gem these days is really, really easy. Bundler provides a great framework generator to get you started. Bundler also lets you install a gem straight from a github repository, so now is the time to say goodbye to your git submodules and start packaging your code into

Bundler makes it very easy to point to a gem folder on your system, and I definitely recommend this approach a lot more. The plugin can be a gem that we can just require, and it can specify its own dependencies in its .gemspec file. But if you really don&

Every programmer makes mistakes.. But every so often though, you make those mistakes that really mess things up. I just made two of them, and feel like a right n00b. Both mistakes simply involved overwriting ActiveRecord methods. The first time, I made an update method in my model. And just
