Oh, I’m sure this’ll end well.

Oh absolutely, I don’t blame KDE or arch repos lol. I did see that it was a KDE update but somehow didn’t clock the version number. I had it in my head that KDE6 was much farther off.

Didn’t realize this was happening and yay -Syu went brrr and it broke my shit. Probably doesn’t help that I’m running nvidia with linux (endeavouros). Wayland doesn’t work at all (black screen on login with only mouse ptr, wrong resolution), while Xorg is now much less smooth e.g. on the switching desktop animations. Moving windows around and in-window graphics are fine. Some graphical config stuff changed too; I’m still taking inventory.

I’m also currently playing with nvidia vs nvidia-dkms with different kernels to see if that solves anything.

EDIT: Looks like that my configuration was failing to set nvidia_drm modeset=1 correctly due to my unfamiliarity with dracut. Manually adding nvidia_drm.modeset=1 to my kernel cmdline makes Wayland work (and quite well at that), though Xorg is still laggy.

One thing that helped me intuit the “sidereal” result (4) was to consider what happens as the radius of circle B approaches 0. At least in my mind, it seems pretty clear that A has to undergo at least one rotation.

That said, I am unsure that I would have caught this as a test-taker. Derek’s videos always have some “trick”, putting me on guard, but in a testing scenario I would have seen the answer for 3 with no answer for 4, marked it down, and moved on quickly.

Maybe a dumb question, but if all of the vehicle’s bells and whistles are meticulously recording my every move… how do those data get back to the auto manufacturer anyhow? I read the article and the “how that works” link, and sure it mentioned phone connectivity, but if I don’t connect my phone, then my car presumably has no way to communicate what it collects… or are there a bunch of extra radios that phone home (satellite, cellular…)?

They are basically shortcuts. For example, I can type “!w ibuprofen” into DuckDuckGo (or the address bar because I have it set as my default search engine) and be brought immediately to the wikipedia page for Ibuprofen. There’s also !yt for youtube search, !so for stack overflow search, and many more.

DuckDuckGo from the browser, because 90% of the time I can get where I want with the appropriate ! bang from the address bar.
