[1,2,3,4,5,6,7,8 ][0..1]

Look at documentation http://ruby-doc.org/core-1.9.3/Array.html#method-i-5B-5D.

Generally good advice is to bookmark this page.

Could you not just do [1, 2, 3, 4, 5, 6, 7, 8][2..-1]

If you are using Rails, 

%w( a b c d ).from(0)  # => %w( a b c d )
%w( a b c d ).from(2)  # => %w( c d )
%w( a b c d ).from(10) # => %w()
%w().from(0)           # => %w()

And, of course, you can just you plain 'ol Ruby for this too:

a = [1,2,3,4,5]

a[2..-1] # => [3,4,5]

%w[ a b c d e ][3..-1] #=> ['d', 'e']
