self is the implicit receiver, ie calling self.find(:all) is the same
as calling find(:all). Sometimes it is useful to make it obvious what
you are doing
def self.list
...
end
creates a class method. The second example you gave probably wouldn't
run, unless the model had an instance method called find. More likely
is that you find something like that inside a
class << self
def list
...
end
end
in which case it is identical to the first example
