Back in the day, the blue screen hex codes were actually insanely useful for debugging. Honestly? I think most (all?) linux distros could learn a lot from ACTUALLY showing the error when the machine dies a horrible death rather than assuming people will dig through the right log files before they rotate.

But I know a few years back (… so probably over a decade) they started having QR codes instead. Which sounded awesome until you try to use one and realize they all go to the same generic help page. Not sure if the hex codes were still there.
