it's covered in the videoI just watched that video recently. Very interesting of course. But I was surprised that people apparently took the cosmic ray thing seriously. I remember back when pannen first posted the bounty for that, and I always thought the cosmic ray thing was basically just a joke. I never knew there were so many articles and videos running with that seriously.
tl;dw a bit flip can recreate the glitch, but it probably wasn't a cosmic ray that did it
