A free Second Edition IDL Programming Techniques book
to the first person who can find the simple word I
embedded in this binary sequence:
0 1 1 0 1 0 0 0 0 0 0 0 0 0 1 1 0 0 1
0 0 0 0 0 0 0 0 0 0 0 1 1 0 0 1 0 0 0
0 0 0 0 0 0 0 0 1 1 1 0 1 1 0 0 0 0 0
0 0 0 0 0 1 1 0 1 0 0 1 0 0 0 0 0 0 0
0 0 1 1 0 0 1 0 0 1 0 1 0 0 0 1 0 1 1
0 0 0 0 1 0 0 0 1 1 0 1 1 0 0 0 0 1 0
Cheers,
David
