Did you mean to say "multiple of two"?  'Cause that's what your code seems
to be doing.

Different story but not necessarily nicer:

data << (" " * (data.length % 2))
data << (" " * ((data.length + 1) % 2))

If you really meant "power of two" a somewhat weired version:

data.ljust( ( "1" + data.length.to_s(2).gsub(/1/, '0') ).to_i( 2 ) )

:-)
