A True Commitment's What I'm Thinking of

on 17 Oct 2021

%%%%% You wouldn't get this from any other computational engine!

%% But really, how can I be committed *solely* to MATLAB???

%%% MATLAB has a great interface to Python, which ...

%%% opens up some interesting options

n=@(x)read(py.os.popen(x));

%nixd = @(cmd) disp(n(cmd)); % For displaying

n('wget https://c1.thejournal.ie/media/2018/10/gallery-1448452218-rick-astley-never-gonna-give-you-up-752x501.jpg -O b');

g=uint8(str2num(char(n('djpeg b | od -An -w1 -tu1 -v'))));

%m=752; % the resolution

%n=501;

for m=1:3

q(:,:,m)=reshape(g(15+m:3:end),752,501)';

end

imshow(q)

%% Explanation:

% Using python, we expose the system shell. HOWEVER, most of the useful

% python image packages are missing. We also do not have access to file access for

% the mini hack. (The "hack" part of this really is a joy!) So console

% linux to the rescue!

% Download any old image you want, convert the jpeg to a PPM file, output

% the PPM file as an array of integers, reshape into RGB arrays and

% display!

% I think this is my last idea, but maaaay be using this technique to meme

% a bit more next week. I'm pre-emptively sorry!
