As an older engineer I have finally convinced my younger protege the value of islandization.
Islandization is the process by which experimental industrial computing stations are cut off from their respective corporate crap intranets.
Numerous times now the typical security sweeps, intranet address changes, corporate policy changes have wiped out the industrial functionality of realtively stupid embedded computers connected to the internet. It is something as an engineer in charge of the control of experimental industrial processes I will never, ever in my lifetime recommend again, the connectivity to the internet as a benefit.
An “operating system” which requires damned near daily “updates” is by any definition a piece of crap. Once I, as an engineer have certified that the software does indeed do what I think I have programmed it to do I refuse to take the blame when is ceases to function simply because it “updated” itself. Yes, I am talking about the great Satan, Microsoft.
