 "GCHQ Launches Cryptography App for Budding Codebreakers"

I have not yet seen the Cumberbatch flick Imitation Game and was wondering if it gave any credit to the Poles, who had cracked the first generation of the Enigma. Prior to 1938 there was a disgruntled German turncoat who provided intel to the French (who shared it with the Brits). Both the French and Brits were stymied, and passed what they considered useless intel to the Poles, who then cracked Enigma. For years the Poles managed to read everything put out by the Germans, and even had created a mechanical device to do the work. Then the Germans increased the number of rotators from three to five, and the plug-connections from six to 20, requiring huge additional work. [See Technical Details of the Enigma Machine]. Two weeks before Poland was invaded the Poles gave the Allies what they had on Enigma, shocking them. Without that head-start the Bletchley Park effort would have failed.The market parallel to this is that someone else's research castoffs may be useful to you. Just because someone else has failed to find significance, does not mean you cannot gain utility. Our own most useful tool was a castoff from someone else who failed to make it work.

    Considering that many GPUs internally remap quads to triangle pairs anyway, wouldn’t it be preferable to skip straight to Delaunay triangulation?
