For VMSClusters 8 to 10 years seems to be a pretty common uptime for long lived clusters. I worked a gig a few years ago that had a VMSCluster that was up for 19 years at that point. Started on alpha, migrated to itanium, then I helped migrate it to x86. It was the oldest I've personally seen, though I have heard legends of much older.

My current contract has a PDP-11/70 running RSX-11 that's been up since 1992. It's uptime is longer than mine! Poor thing is getting retired next year though.

I worked on replacing some PLCs a number of years ago that used drives like these and used the energy from the spin down when power was lost to write anything important to a short 8-track like infinite tape loop, gracefully-ish shutdown, and send messages to the monitoring gear.

I'm a lispworks user for a few projects. The killers, generally, for an enterprise project are the smaller binaries and java interface. I know of a few places that write gui apps in lispworks, but many (most?) projects with a user interface use some web framework stuff and only do the backend in lisp. The java is a killer feature for lisp adoption. A lot of companies use java heavily and being able to easily interface with that stuff is often a technical requirement and if not a technical one, a management requirement.

> 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.

This is anecdotal but I use pci passthrough and drm hasn't yet been much of a problem except for older games.

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".

Little did they know of what was to come.

No I'd bet he's getting avgas. That's avgas price territory.

But depending on the altitude you're at getting that mask on is wishful thinking. Don't bet on your pilots being conscious after a plane depresses.

Both are kind of correct. If it's laying where it shouldn't be it's debris, but if it's plowed through the windshield it's damage.

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.

Almost none came from Airbus. Really you could almost say they came to Bombardier’s aid.

No, the SS did in fact have academics in their ranks to produce things that link the SS/Nazism to the "German past," to scientifically show the "superiority" of the German people, and to "quantify" how exactly everyone else was less human than the German "Aryan" peoples.

The SS was much more than a military group. It was a weird mix of paramilitary organization, police force, academy of sciences, academy of arts, men's club, cult, and think tank.

Total conjecture but it was probably factored in. From my standpoint if I knew it was going to sag, I would use that to my advantage if I could and, if not, at least factor it in.
