Web fonts are pretty much all the rage. Using a CDN for font libraries, like TypeKit or Google Fonts, will be a great solution for many projects. For others, this is not an option. Especially when you are creating a custom icon library for your project.

Rails and the asset pipeline are great tools, but Rails has yet to get caught up in the custom web font craze.

As with all things Rails, there is more then one way to skin this cat. There is the recommended way, and then there are the other ways.

The recommended way

Here I will show how to update your Rails project so that you can use the asset pipeline appropriately and resource your files using the common Rails convention.

Install with Homebrew

brew install redis

Set up launchctl to auto start redis

$ ln -sfv /usr/local/opt/redis/*.plist ~/Library/LaunchAgents

/usr/local/opt/redis/ is a symlink to /usr/local/Cellar/redis/x.y.z (e.g., 2.8.7)

So you want to generate ISO8601 formatted timestamps in Ruby, but need resolution finer than a second?

First, make sure to require 'time' in order to get ISO8601 formatting. But that gets you this:

2.1.0 :001 > require 'time'
 => true 
2.1.0 :002 > Time.now.utc.iso8601
 => "2015-11-12T04:46:43Z"
