In highrises with lots of stops and users, it uses some more advanced software to schedule the optimal stops, or distribute the load between multiple lifts. A similar concept exists for HDD controllers, where the read write arm must move to different positions to load data stored on different plates.
Comment on Still booting after all these years: The people stuck using ancient Windows computers

The elevator was running Windows XP.
Clearly a extreme case of overengineering. An elevator has no business running more than a few microcontrollers.

This requires little more than a 286. It’s an elevator. Responding in times measured in seconds. What kind of computations do you think are required here? Imaginary quaternion matrixes? Squared?
GenosseFlosse@feddit.org 10 months ago
Yes, but if you have it as a Windows program it’s easier to configure on a screen with mouse and keyboard, change settings, display help files or give the source code to someone else to make changes or add features.

also it was probably not too expensive to grad a bog standard PC off the shelf and do it on that. I’ve see raspis in the wild doing tasks like that. and those will be outdated by the time they’re replaced too

But how else can it book requests for priority access, and verify the credit card for whoever booked the elevator?
MonkderVierte@lemmy.ml 10 months ago
Ah, the blossoms of unregulated wild capitalism.

Qube cinema servers only got off XP in 2015. They’re still on 7 though.

It’s probably only the screen component that is running an old version of embedded windows.

That’s what I think too. And then I see “Their systems are built into everything around us”, which basically only applies to PCs and laptops. What is built into pretty much everything around us is GnuLinux.

What is built into pretty much everything around us is GnuLinux.
Many things, but far from that.

Yeah, it was a statement, not a question. But it’s partly my fault for not using the comma appropriately. Fixed.

Not even GNU - just Linux.
Yeah yeah, something something GNU/Linux blah blah copypasta…

Screen? In a elevator?

I hate that you are right.

Yes? That is not that unusual and it is mentioned in the third sentence of the article.
I rode up to the 14th floor, my eyes were drawn to a screen built into the side of the lift.

Those screens can easily run on an integrated Raspberry Pi microcontroller, they dont exactly have complex graphics
HugeNerd@lemmy.ca 10 months ago
But how else can it be safe to connect to the internet?
MonkderVierte@lemmy.ml 10 months ago
You need to be on-site to fix it anyway, just access the debug port.
