Windows NT 3.5 and later NT 4 had C2 security certifications - assuming the system was not connected to a network, and didn’t have floppy drives (this was before USB was a thing).

There’s the old saying that Debian is available in three flavours: Stale, rusting and broken.

Because it isn’t. This impacts when the scheduler kicks in, not on how many cores stuff is running on. With fewer cores scheduler is faster triggered again, and and at 8 cores the adjustment for that stops. Which may be an intentional decision to avoid high latency issues.

You have a list of systems you’ve connected to in known_hosts, though. And the config file is easy enough to parse - throwing away the stuff you don’t care about - to expand on that list.

I assume you mean “lookup”, as import doesn’t really make much sense.

I’m currently using this with wofi, though I’ll eventually rewrite it as anyrun plugin, which provides a bit more control:

There’s a lot of other stuff where Wayland improves the experience. Pretty much everything hotplug works to some extend on X, but it’s all stuff that got bolted on later. Hotplugging an input device with a custom keymap? You probably can get it working somewhat reliably by having udev triggers call your xmodmap scripts - or just use a Wayland compositor handling that.

Similar with xrandr - works a lot of the time nowadays, but still a compositor just dealing with that provides a nicer experience.

Plus it stops clients from doing stupid things - changing resolutions, moving windows around or messing up what is focused is also a thing of the past.

especially if you have Nvidia

This is something that needs to be highlighted over and over again: Don’t buy nvidia if there’s ever a chance of running anything but Windows.

Did the device happen to be the CueCat?
