       | This didn't cause an outage, but I was endlessly amused about

       | embedded pngs of each ship detection into an xml file and had
       | some limit I'll never remember on the maximum number of such tips

       | It was actually a testament to the thoroughness with which the
       | NRO regression tests its shit, but the complaint was that the
       | simulated scan the program was running detections on crapped out
       | after something like 30,000 detections, which is already more
       | ships than the US Pacific Fleet and probably more ships than any
       | foreign Navy has in every ocean on the planet, certainly more
       | than will ever be contained in a single image.

       | But in case I'm being 1981 Bill Gates level naive here, they are
       | in fact prepared for the eventuality of gigantic swarms of
       | microships taking over the oceans because of that regression
       | test.

         | I guess).
