Use Ruby arrays for repetitive resource declaration
In a Chef recipe you can use a Ruby array to make declaring multiple resources with the same attributes.
For example, this:
directory "/foo/bar" do
owner 'foo'
end
directory "/baz/bat" do
owner 'foo'
end
directory "/blah" do
owner 'foo'
endCan be changed to this:
["/foo/bar",
"/baz/bat",
"/blah"].each do |dir|
directory dir do
owner 'foo'
end

This gives me even more incentive to learn more Ruby and put this into practice.

To keep your array definition tidier and avoid odd spacing, you might go for something like this:
%w[/foo/bar /baz/bat /blah].each { |dir| directory dir }If you need to specify attributes, using the longer block syntax is preferred:
%w[/foo/bar /baz/bat /blah].each do |dir|
directory dir do
owner 'foo'
end
}

Intuitive, elegant, and fun to write. Things like this are why I love Ruby so much.
