To each their own I suppose. “Catsup” has always just seemed like a weird affectation to me.

For the first one… Not sure I get it. It was originally ketchup, and has been predominantly spelled that way for hundreds of years. It was spelled that way before ketchup even had tomato in it.

Typically people propose switching everything to UTC.

The read this doesn’t work is because humans are still bound by a diurnal cycle and you won’t have everyone wake up at 0800, since for some people that’s the time in the middle of when the sun sets and rises.
So you still need to communicate to people across space where the sun is or will be for you at a time in the future, or otherwise relate where in your wake cycle you’ll be.
Tied to this is legal jurisdictions. Within a legal jurisdiction it’s important for regulatory events to be synchronized. For things like bank hours, school hours, government office hours, things like “no loud noises when people tend to be sleeping”, “teenagers old enough to have a job aren’t allowed to work late on school nights”, and what specifically constitutes “after hours or weekend labor” for the purposes of overtime and labor regulation you need your definition to be consistent across the jurisdiction. Depending on where you are in relation to Greenwich a typical workday can start at 1900 Friday night/morning, and extend until 0300 Saturday morning/afternoon. Your “weekend” would start when you woke up around 1800 Saturday evening/morning.

Right now we solve this problem by deciding on a consistent set of numbers for where the sun is across some area that inevitably lines up with legal jurisdiction. Then we use a lookup table to translate our conception of where the sun is to where it is elsewhere.

Without timezones you instead need to use the same type of lookup table to find the position of the sun at the time and place of interest, and then try to infer what the situation would be.

We have UTC now, and people inevitably already use it where it makes sense. It’s just usually easier to have many clocks that follow similar rules than it is to have one clock that’s interpreted many different ways.

Okay. You’re still doing tech support either way. I have no way of knowing how much free tech support you’re willing to give, hence my caveat of how much you’re willing to support them.

Netflix would disagree. People feel like they’re supposed to be getting access to a service, and if they’re not getting it they’ll complain to the nearest party to what isn’t working. In this case that’s you or Netflix being asked questions about why the router isn’t working.
That it’s wrong or irrational has nothing to do with who’s getting asked the question, and who’s the first line of troubleshooting when the service doesn’t work.

If people didn’t ask the wrong people questions, Netflix wouldn’t need support articles on how to reset your router.

Honestly, you’re supporting a chunk of her network by being a media provider in the first place. “It won’t play” doesn’t usually come with an assurance that it’s not a device or network issue.

Neither plex nor jellyfin seem remotely worth the effort to provide to others in my opinion, I just felt like sharing that there are ways to afford network protection to locked down devices.

I’ve got no real care for jellyfin one way or another, just sharing that there’s ways to make the network obey.

I think giving people access to my media server is asking for too much trouble personally. Now you’re dealing with forgotten passwords, people using your bandwidth at weird hours, and you basically become the media fairy, responsible for finding whatever it is people want, and then dealing with their issues when their device can’t codec at it for whatever janky reason.

I’m good at setting boundaries with family so it’s not stressful, just more annoying than I want to deal with.

Depending on their router and how much IT labor you care to do for these people you can actually configure a site to site VPN tunnel. All traffic for a particular address range will get routed through the VPN automatically.

It used to be a high end feature but it’s made it’s way into general routers since it doesn’t really require many resources and it lets you label it as having more home office features.
