Someone can correct me if I'm wrong, but the second example actually is a
hash. You wrote:
u.update_attributes(:name =>"Fred", :color => "green")
The arguments you passed in are a hash. It's the same thing as writing:
u.update_attributes({:name =>"Fred", :color => "green"})
Ruby (I think...or is it Rails?) gives you the freedom that if the 'last'
parameter passed to a method is a hash, you can omit the { } characters.
