My grandma uses WhatsApp. The only reason I've ever used SMS is to receive a verification code

That isn't what normalized means in the context of databases.

Also databases store the same data many times over often. For redundancy and load-balancing purposes. Really, federation just takes care of replication somewhat.

I have a ThinkCentre m90q with an i3. It's a few years old. It's a lot more powerful than a Pi. A Pi will not cut it.

You will preferably need something with modern hardware encoding. Support for h265 and AV1 is a requirement nowadays to play high quality sources and find anything for newer stuff. Moreso if you want to watch 4k content.

I live in the Netherlands too, but I'm certain this was an online service from the US. It's definitely a minority of them but it happens nonetheless

That's a good tip. Also: have your servers auto-update weekly. You will forget.

Apple is willfully hampering the ability to intercommunicate between iPhones and Androids

In what way exactly? All the messaging apps I use work fine. I even have the same Signal account logged in through both my Android phone and my iPad.

Nobody I know actually uses iMessage either. It's a complete non-issue as SMS is quite an outdated technology.

Yep just delete the account while you're at it. If it's for work just don't use it on a personal device

My device always shows the WiFi number. It's nice to know since I live in an apartment building with shared wifi. The shared wifi is 4/5 and mine is 6 so I can see at a glance if I'm connected right.

I can't imagine another reason it'd be useful though.

Caddy Reverse Proxy with Basic Auth for services which are critical like my 3d printer. Without auth for other services like my website or jellyfin and such. I use docker for everything so that's another layer of safety for me.

I have port 443 open and use subdomains for most stuff. Some other ports for non-HTTP services but I don't have any right now.

that service will keep working until the next billing day

You wish. I have had one too many services that cancel immediately upon request, even if you paid for the month 3 days ago.

I have an nginx reverse proxy with http auth, myself. It's such battle tested software that I trust it fully

Could you elaborate? I've never heard of that. Although I don't donate to Wikipedia now.
