cosmic rays are what you blame when you can't find the bug
Sometimes you can prove it was a bit flip [caused by cosmic ray, local radioactivity or a glitch in the Matrix], you just need to find the exact bit. A friend of that managed to do exactly that after an error in his monthly accounting software. He proved you could only get the resulting sum if you flipped bit Nth of a certain value during the summation. It took him a while and he had written the software himself.
I post every now and then, but there isn't much to talk about with the old folks 'round here these days. Eventually every comments section looks like a Thanksgiving dinner! Most of my rambles are now on Reddit now.
Keep sharp!
