The write up leaves a lot to be desired. Using QR codes to display kernel oops messages was proposed and demonstrated back in June 2012.[^1] Matt Garret even mentions this in the lkml thread[^2] that the article links to, but for some reason the author did not bother to look into mjg's response. So I am not sure "welcome to the club" is accurate since the kernel has been a member (to the extent that this patch is evidence of membership) of the club since June 2012.
