Moonlight/Sunlight are both really great options. The only problem I've encountered with either is that the mouse cursor is encoded into the video stream itself. It adds a little bit of lag when moving the mouse and makes it feel not quite right. Steam doesn't encode to the stream, so it feels much more responsive. Parsec doesn't either, but it does not support hardware decoding in Linux so you're going to be stuck with an added ~10ms decode time.

Just because this level of cringey fanboying should never be tolerated, here is a hurtful fact: Valve has argued in court that they are a subscription service and you do not in fact own any game in your library. https://hothardware.com/news/valve-loses-french-court-battle

Hey, maybe not quite video gaming, but have you thought about getting into DnD or Vampire: The Masquerade? DnD has lots of open groups to find on Discord or services like Roll20. That gives you voice communication so you are talking and playing with real people. VtM isn't as popular, but is a really great setting and does have at least one massive Discord server for RPing with others (https://discord.com/servers/seattle-by-night-517427294915002371).

I can understand your attitude towards MMOs. I really want to like them myself and keep retrying them, but somehow they end up being more isolating then single player games. I think so much of their content is based around group play that if you somehow manage to go full hermit mode in them like I do, they don't really work. Single player games emulation human interactions so feel more rewarding somehow.

Since you mentioned GW2, you might try other games like that if it worked for you. WoW, Elder Scrolls Online, FF14. The Payday series might also be a good match as it has auto teaming and voice chat. I would probably stay away from card games like MTG: Arena though. Those are incredibly fun, but are based on fast paced matchmaking with little user to user interaction possible.

SFP is pretty straightforward. Most of the SFP modules you can buy you just connect and they work. For something like that, you would be doing fiber to ethernet hand off at a switch. Then you have pretty much everything run to the switch including router and just VLAN isolate. It's not super complicated, but if you never messed with VLANs it might be better to go with something pre-packaged unless you're up for learning.

You could also do a DIY router and run a multi-gig SFP+ network card over PCIe. You still have to purchase a separate SFP module for that, but that is another option.

I set up a backup cell connection to my cable internet connection. Sketchy Chinese 4G LTE modem. My router was a DIY job I set up off of Ubuntu Server. Everything ran to a Cisco switch and then was VLAN isolated. For the two WAN connections, I ran scripts from the router that periodically tried to reach out to several DNS providers and then average response rates to determine if the main connection was up. If not then it would modify default routes and push everything to the cell.

The cell connection had pretty low data cap, so it was just for backup and wasn't a home style plan. I used the old TTL modification trick to get it to pass data like a phone. When I moved the backup to 5G, TTL modification stopped working and I had to resort to creating tunnel interfaces to an actual phone. Since that tunnel is limited in bandwidth to the lowest value, my speeds were really cut in half.

A VPN would give you access to a network, but not necessarily the devices on that network. It adds another layer of security as the user not only has to have SSH credentials/keys, but they also have to have the same for the VPN. SSH and VPNs would really be used in conjunction with each other.

It's onion security.

My understanding was it's bad practice to host images on Lemmy instances anyway as it contributes to storage bloat. Instead of coming up with a one-off script solution (albeit a good effort), wouldn't it make sense to offload the scanning to a third party like imgur or catbox who would already be doing that and just link images into Lemmy? If nothing else wouldn't that limit liability on the instance admins?

Just throwing out a couple of other solutions I didn't see mentioned for DoH/DoT:

1. CoreDNS
2. Blocky

Both of those support encryption and allow for DNSBL. If you are wanting to hand out DNS entries over DHCP it may a problem with your ISPs router there. Either replace it, sit one you do control between it and your network, or run DHCP snooping from a switch to restrict it's DHCP.

No, that wouldn't be a straw man argument. If you're going to try to call fallacy on something you would have to argue appeal to hypocrisy. However the hypocrisy is based on your post and previous posts calling for a boycott for something you find morally reprehensible while at the same time using a platform created by the morally reprehensible. One you have a problem with the other you do not. It calls into question your own morals when they only serve you when you think they should. That's all.

J.K. Rowling’s anti-trans rhetoric and activism has enough influence to lead directly or otherwise to the further persecution and discrimination against an already marginalised minority group.

So does Lemmy and its developers pro-Uyghur slavery/genocide viewpoints. That doesn't stop you from using or enjoying Lemmy though. Everyone has their own red line. Lemmy hasn't crossed yours just like J. K. Rowling hasn't crossed theirs.
