Below this line you can do:
```ruby
let!(:article1) { Article.create(:title => "First", :link => "http://www.example.com", :created_at => 10.seconds.ago ) }
let!(:article2) { Article.create(:title => "Second", :link => "http://www.example.com", :created_at => 5.seconds.ago) }
```
and remove the `Article.create` lines in the specs
