This post starts with " Software that controls (nuclear) power plants, elections, pacemakers, airplanes, bridges, heavy machinery " and proceeds to list pracitises you should apply to, say, shopify or facebook. Those practises are no where near robust enough for industrial software. Such is the degree of risk adversity that the use cases above can run on out of date hardware and ancient software, and change is deplored in favour of workarounds. Why is that ? Well engineers see risk differently to us - they will attempt to remediate all risk, whereas we will mitigate that risk. That mitigation is the substance of the post, and I have no quibble with that, but to assume that is best practise for my ICD is naive. The author proposes that doing what we do well is sufficient, whereas we need to shift our thinking to a world in which we are in complete control.
