> Question: is there a reason pid type control is never a thermal option? Or put another way, is there something about the desired thermal characteristics of a computer that make pid control undesirable?
I've only every seen something like this in really high reliability equipment because they're worried about repeated thermal expansion causing cracks in the boards/solder joints. There is, often, heaters available for use if the temperature gets too low.
For most equipment I think that the juice just isn't worth the squeeze so it isn't done.
Orangeburg pipe is the tar paper stuff. It's a time bomb. Not only does it break down with use it also flows (flattens with gravity/overburden pressure, bends over unsupported sections run through walls/floors, etc) over time as well, especially in a hot environment. So even if it doesn't get much use it will collapse and/or stretch and break.
It's not just economics there. Weimar was a garbage fire from top to bottom, and that made extremist groups that promised to fix the nation actually viable. People are much more willing to vote for loons if everything is broken and no one has really done much of substance about it. In their eyes they have nothing to lose. A common thought then was "Maybe these nazi/communist/anarchist guys can fix things. They seem well organised even if they are a bit wacky. How could they make things worse? We'll just vote them out if they don't deliver the goods like we did the last guys".
> "In a decree issued on 17 February 1933, Göring ordered the Prussian police force to make unrestrained use of firearms in operations against political opponents" and (as mentioned in previous posts) the police were not the only armed paramilitary group in play.
One additional item of context is that there were many people (including Ezra Pound and Oswald Spengler) going about saying that WWI+depression had proved that the edwardian vision of progress and social democracy was broken forever, and something new needed to be tried.
They’re great cards and easy to write drivers for. I still use one in one of my thinkpads for wireless because it used to be the only card supported by 9front and plan 9 back in the day.
