@clacke @makdaam @hendric I would ask the other way? What is actually useful in there? What do you think can be learned?
Because nearly all things pointed as lesson learned go strictly again what we know about producing working software or are atrociously unpractical. On top of that, it creates a feeling that only "software controlling super critical stuff should be concerned" aka nearly noone.
And it is deeply rooted into hardware/software issues, which are not what most devs deal with
