It's a normal browser setting left over from the early days of the Internet, when most pages did little or no theming (or did it badly). My primary browser is Pale Moon, which exposes the setting as a dropdown under Preferences > Content > General > Colors. Firefox also exposed the setting on its settings page the last time I checked, although it may be a checkbox there. It's also a boolean in about:config, browser.display.use_document_colors.
Chrome-family browsers may not have such a setting, unfortunately. The only one I keep handy is Vivaldi, which doesn't have it but does have a "Force a dark theme on all websites" checkbox (under Settings > Appearance > Website Appearance).
I chose a slightly different way of achieving what that extension does, and long ago set my browser not to allow websites to choose their own colours. That does partially break a few sites that don't handle their images properly, but overall it's workable and gives me white on a slightly different dark colour for each browser profile.
The colour scheme. White screens are one of the things that trigger my migraines.
This in turn leads to my modifying several other visual aspects of the desktop, because a lot of widget set themes come with scrollbars that don't work well with really dark colours. I also turn animations and automagic snapping and desktop navigation facilities off, because I find them annoying. Kindly behave like it's 1999 and don't do anything I don't explicitly tell you to do, Mr. Desktop.
And then I embed a conky instance in the second desktop for general monitoring—CPU activity (composite and by thread), memory in use, disk space, network usage, temperatures, fan levels, and greediest processes all conveniently in a single view that doesn't require me figuring out what I did with the window.
KDE provides a very large set of services. This makes it something of an elephant in the world of Linux desktop environments. Lighter DEs should fit in less than 1GB (that's anything other than KDE and Gnome). I think the last time I checked my system with just the DE up and nothing open, it was using on the order of 200-300MB. However, the lighter DEs will also do less by default.
It should be safe to kill baloo, but as others have already said, you will see some tradeoffs in how file searching works if you stick with KDE. If I'm not mistaken, it may restart periodically to index new files unless you go to some effort to exorcise it.
I'd be more impressed if they stopped bundling random crap. It's their unwillingness to use upstream's dependencies and toolchains that makes Chromium a nightmare to package on Gentoo, and flatpaks are not going to fix that. They bundle clang, rust, and so many additional libraries that the "must keep bundled version to prevent breakage" list is almost 300 items long. This is not the correct way to ensure reproducibility, guys.
I'd be interested in tests across hardware of different ages (but as others have said, same/similar DEs/WMs/compositors as much as possible, please). While I have no proof, I'd guess that Wayland is making assumptions that would make it less efficient on some older kit.
Exactly. I mean, I like OpenSCAD, but there are things that are effectively impossible to do in it that are easy with a more visual piece of modelling software. Good for utility parts that need precise tolerances, not so good for dragon statues.
Traditionally, "freezing" means that the system doesn't respond at all. More than likely, your system is just swapping heavily and slowing down to a crawl. If that's what's happening, the hard drive activity light will be on constantly.
The best fix for this is more memory, but RAM is currently expensive. If you can't afford to buy more, you may have to try to cope in software. First, do The Bleeding Obvious: close any programs that you don't immediately need before you start that Discord call. This includes not leaving unnecessary webpages open, just in case.
See what your distro has to say about swappiness and how to set it. You probably want a value lower than the default 60, maybe even as low as 0.
If it gets worse over tme, it's possible that something you're running has a memory leak. You may be able to figure out what using top or similar and seeing which programs' memory use grows over time. Restarting the greedy ones periodically may be able to keep your system from bogging down, at the cost of some inconvenience.
Moving to a bare compositor rather than the relatively heavyweight KDE might also free up some RAM, but I'm not sure how much that will actually help.
To get rid of the vulnerability, just blacklist the Open vSwitch kernel module if, for whatever reason, you have it installed. As far as I can tell, you probably don't need it unless the machine in question is acting as a switch or router.
Okay, so did they account for the bots that claim to be Windows PCs? (I'll bet there are still some running around that identify themselves as IE 6, although those may finally no longer be the majority of all bots.)
Try blacklisting sof-audio-pci-intel-cnl and see if you can get snd_hda_intel to load instead. The one time I tried the sof- driver, I couldn't get it to work.
As a Gentoo user who still compiles my own kernel for each machine, I say, Arch users have no idea what a distro that really doesn't hold your hand looks like. (Hell, even Gentoo pales in front of LFS.)
Hadn't heard about those, but a quick search shows those aren't standard barrel connectors, although they look similar. The Dell connectors have a third pin for data. Normal barrel connectors only have two pins.
For the OP, that means that if your laptop is a Dell from the period where they were doing this, you need a specialized cable and charger intended specifically for Dells.
Depends on the connector. "Kind of fits" and "isnt usb-c" makes me think you might be dealing with the type of barrel plug that's very common on pre-USB-C non-Macs.
Unfortunately, barrel plugs tell you zilch about the power supply they're connected to. They're a dumb connector with no data capability whatsoever, and I've seen the same size of plug on power supplies with output anywhere from 3V to 24V. You need to look for the data panel on the old power supply and make sure the new one has the same voltage, the same or larger amperage, and the same polarity.
Polarity on a barrel plug is marked by a symbol that looks like this or this. Make sure the old and new match. Nearly all barrel plug power supplies are center-positive, but better to get it right the first time and avoid any risk of damage to your laptop.

Perhaps if you're younger than the horse, it owns you instead.
That may have been the point.

Yes, precompiled packages are available, although only for 1-2 common combinations of USE flags per package.
To get rid of the vulnerability, just blacklist the Open vSwitch kernel module if, for whatever reason, you have it installed. As far as I can tell, you probably don't need it unless the machine in question is acting as a switch or router.
No need for an urgent kernel update this time.

Now you got me curious, so I got up and checked:
2008 HP laptop: Appears to be a standard barrel with no center pin. (Also has yellow trim and is in-line with the cord.)
Circa 2013 HP laptop: Has the connector with the center pin. (Larger than the barrel on the 2008 model, and at right angles to the cord)
So it's era-dependent (and I used that 2008 model too long). TIL.

Depends on whether you're talking about additive or subtractive colour. Yellow is primary in a subtractive system, but not an additive one.
Most of its functionality is just reimplementing things that already existed, with an incompatible interface.
