Functionally they're all interchangeable, especially bi/pan. The biggest difference between the three is their flags.

Try taking a look at the way glueten implements port forwarding with protonvpn. Hopefully it helps you piece together a script that works for your setup.

My understanding is that debrid servers do not seed, which is the primary reason I've been turned off to the idea of using one
Never read this article before, thanks for sharing!
It supports more codecs and I believe can store more tracks compared to MP4. Whenever I download a high quality movie or tv show, especially if it has multiple audio tracks and subtitles to choose from, it is always packaged in .mkv
Blog post about Threema that changed my mind against it: https://soatok.blog/2021/11/05/threema-three-strikes-youre-out/
Jellyfin natively supports playlists. Symphonium also supports playlists, both local and from your Jellyfin server.
It's not altruistic, but the blog post outlines why they're doing this. Underappreciated volunteer-run dependencies can have security flaws that impact huge swaths of the tech sector. Investing a few grand now to secure those tools instead of significantly more money to do damage control after a vulnerability is found and exploited makes sense. It's a preventative measure that benefits the entire industry, GitHub and its parent company Microsoft included.
To my understanding, vacant housing refers to housing in which someone is not currently living, including housing that is under repair/renovation, needs repairs, or is abandoned/condemned.

Also, of the housing that is vacant, two thirds are vacant for 6 or fewer months, and ~85% are vacant for 12 or fewer months. The median duration of vacancy is about 2.4 months. Only a small portion of vacant housing is actually vacant in the way people typically think when they hear vacant housing. Freeing up the ~10% of housing that is actually vacant long-term the way people think just would not alleviate the housing crisis. We gotta build more housing, y'all.

Unfortunately it isn't actually that straightforward. That number includes abandoned and run down homes that are currently unlivable, houses that aren't actually on the market because they're being remodeled, they exist in the middle of nowhere where people don't want to live, etc. Fundamentally, the problem with housing in the US is supply. We don't build enough housing in the places people want to live.
While on the topic, a lot of people say that housing is commodified and that's why it sucks. This is not accurate. Housing is treated as an investment that should go up in value over time, not a commodity that can be easily bought, sold, and traded.
If anybody is interested in learning more about housing in the United States from someone who studies this full time, I recommend Clayton Becker
What in the fuck is this guy talking about? Me when I'm addicted to social media but refuse to turn off notifications or curate my experience. The beginning of that second paragraph is a strange concoction of words that doesn't actually communicate anything. I skimmed through the article and it devolves into a rant about a play the author didn't enjoy and other stray ramblings like this:
This entire article feels like a paper you didn't start until the night it was due and only remembered about after you took a weed gummy.
