Say I'm diluting a chemical at 10:1 (that's 11 total parts) for a final volume of 240 ml. 240 ml / 11 = 21.8 ml of chemical. Now to find the water: 240 - 21.8 = 218.2 ml.

If you want to pay for or pirate a font, there's of course Albertus. The best free (OFL) font I've found with a similar look is Della Respira, only a single-style font:
I'm not sure how you plan on using a proportional font in the terminal, though.

It's not CentOS 3, it's CentOS with Linux kernel 3.10 (a 2014 kernel). This was supported in RHEL/CentOS through 2017.
Still very dated and a bad idea, of course. And even weirder that it's on a new machine. I've seen tons of stores using Win7 past it's EOL, but on older hardware.
You can just use MKVToolNix to add the second track to the MKV file after rendering, it's still another step but doesn't require re-encoding.
If you're just trying to multiplex tracks and not actually edit the video, I'd recommend doing it entirely with MKVToolNix and skipping Kdenlive for this use. I've done this previously to combine a subbed video and a dubbed one into one file, you can offset or stretch the audio if needed as well.
Inter is great, I've been using it (TTF hinted) as my UI font for years and it renders very sharply. I'm on Debian and KDE Plasma
It's not made by Google though, it's this guy, Rasmus Andersson
What is it good for?
I've always used XFS on spinning drives and F2FS on SSDs. No issues, they're very solid
Soulseek is good. It's a peer-to-peer sharing service, so you can just choose who to download from rather than waiting in a queue. You can find things in FLAC if you want it, or in various lossy qualities.
Were you watching 4K77 and 4K83 with Digital Noise Reduction? The movies are distributed in two versions, one with film grain and the other with DNR.
Maybe if the first number includes tanks of Russian manufacture in Ukrainian service
I'm not knowledgeable about kernel tweaks, but switching DEs is very easy on Debian and should not cause any problems. Just install the desktop metapackage (e.g., "task-kde-desktop") and you'll be able to choose it from the login screen.
