The staff at a metal-recycling company we were installing at, started complaining that the furnace would stop optimizing overnight. We investigated.
The controller computer would go into power-save mode, which suspended our control app. So the furnace would just sit there wasting power and burning up electrodes.
I calculated that during that week our furnace site wasted more power than all the power saved in America that year with power-save mode.
It would literally have been better if they'd never invented power save mode.
So be careful how much fiddling around we do. The law of unintended consequences will bite you in the butt every time.
Linux as she is written comes with no warranty of anything, it is much more “consumer grade” than those variants of windows.
I think even enterprise linux does not come with support for industrial applications.
(I say this as a huge proponent of Linux supremacy)
Only if you considered the purpose of power-saving mode to reduce total energy usage, vs to reduce amount of power (and consequent wear & tear) an individual machine uses. However that MS would release a feature like that which automatically kicks in on upgrade without any sort of consideration of what the machine was used for - it could be running life-support systems! - seems an issue. But I'd also expect a fair bit more diligence on behalf of engineers responsible for monitoring and maintaining systems that need 24x7 uptime.
i shudder at the thought that a critical piece of life-support anything would be running a windows based OS.
The issue I was originally investigating was SQL timeouts; turned out the virtual servers were putting their virtual nics to sleep.
Also known as: If it ain't broke, don't fix it.
Meh, I see Ubuntu black screens in public appliances as well.
Life support systems don't run windows. And if you're running consumer windows on anything critical, you fucked up.
