Add the simple-rss Gem to your Gemfile:
gem 'simple-rss'
Update your bundle:
bundle
You need to update the image/image.html to support remote images. So, I have just updated it to the following, since I do not use the assets:
<img data-bind-src="image" data-bind-width="width"/>
Put the startup_quote.rb to jobs/startup_quote.rb.
Finally add the startup_quote.erb contents to your dashboard.
Yay Ruby!!
