Replace MS Word smart quotes with straight quotes

MS Word's smart quotes cause all kinds of problems when pasted into web applications as they're none standard characters. In Ruby, the following works, replacing them with ' and " , which can then be turned into the proper entities with textile etc.

string.gsub! "\342\200\230", "'"
string.gsub! "\342\200\231", "'"
string.gsub! "\342\200\234", '"'
string.gsub! "\342\200\235", '"'

Perhaps someone can implement this in a nicer way.

Alternative zebra stripes approach using a helper

This is a tidy way of alternating classes on some element.

In the view:

    <tr class="<%= alternate %>">

In your application helper:

def alternate(str1 = "odd", str2 = "even")
   @alternate_odd_even_state = true if @alternate_odd_even_state.nil?
   @alternate_odd_even_state = !@alternate_odd_even_state
   @alternate_odd_even_state ? str2 : str1
end
