Did the device happen to be the CueCat?

There’s a lot of enterprise stuff that only ships as binaries. I had some fun in the late 00s trying to find the most recent distribution still shipping packages for egcs as that was the only compiler supported by the Lotus Domino SDK.

(For the younger ones here: There was some disagreement about gcc development, which resulted in the egcs fork. It got merged back into mainline gcc by he late 90s already, though)

At the time when the Loki ports happened it was a great thing - before that you pretty much had doom and quake available. Nowadays things are better with steam, but it’s quite likely that we’ll see some stuff break there in a few years as well, at least for older games.

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.

They were interesting, but only good for a very narrow purpose - not really a good thing when the trend back then was going away from special purpose machines toward general purpose.

intel didn’t plan it to be just a special purpose CPU - but it just ended up that way. That they gave their first customers free Alpha workstations for crosscompiling code as that was faster than native compilation should tell you everything you need to know about suitability of itanic as general purpose system.

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:

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.
