This is how I started.
I have a dynamic IP and a router provided by my ISP. IP assignations, DHCP, are managed by the router. I went with DuckDNS for a free DNS service. Select a name and you get a myname.duckdns.org that you need to assign to your dynamic IP. duckdns has instructions to create a cronjob to update your dynamic IP on duckdns.org. (Routers come in all shapes and configs, chances are that this won’t work for most people) On the router, I assigned a static IP to the server hosting Jellyfin, in case of a reboot Jellyfin would always have the same IP. On the Ports page I opened up the default port for Jellyfin at that IP. I could then access Jellyfin outside of my local network using myname.duckdns.org:1234
This is not what I have right now, but it helped my get started.

What is MOTD?

I’d say you install the VPN on the home machine, then when you turn on tailscale on your phone, the traffic should be Phone->home machine (exit node)->VPN

I’m using Lawnchair because it allows folders in the app drawer and I fell the need to group apps. Does Murine do this?

I have a very similar setup. I work from home and use a tablet with symphonium for radio and my personal collection. When I’m in the car since I don’t have Android Auto, I just connect my phone with the Bluetooth. And I use tailscale as the VPN.

Some of us have kids who absolutely love dangling wires

Great for self-hosting if its something you use. Not really a homelab thing, these two things are not necessarily the same either. My hosted services for the family are entirely segregated from my lab, which does a very different job.

My thoughts exactly. OP should look for something else to host on the homelab, there’s plenty out there.

Clever. I’m just starting to mess with Caddy. Been struggling with Vaultwarden lately and your solution might fit my needs.

I think this should be talked about more. Does every selfhosted app need to be public facing?
I use Immich as a backup service, so i really don’t have any need to have it public facing. It connects when I’m home. Same with contacts/calendar.

Create your post and put a notice saying it might not be under the rules. I agree with the previous post, the traffic is not overwhelming so the admins might let it stay. We’re human after all.
As for your question, I don’t think I have any community. I usually watch some hardware related channels on YT.

I went with GitHub. In the end it’s just an OAuth service, to provide identity. It’s not used to gather data on you (just the same we already share by visiting regular websites).
I’m still gonna lookup Headscale and Wireguard because It’s been on my radar.

Thx. I’ve tried the musicbrainz Picard app and I don’t like it, I’ll check quodlibet. I’m using beets at the moment but it’s terminal based. All on Linux.

Out of curiosity, what’s the app that she’s using?
I’ve been looking for a good tagger.

I’m using airsonic, a foss alternative to subsonic. It can have multiple accounts and shared playlists

I use bandcamp regularly, although i tend to just buy and download from the webpage, and then I let beets organise and copy the files into predefined directories. It also can do zip files.

Yesterday I got into a “funny image” post showing someone who couldn’t use the correct date format online and quickly found a comment, with tailors, about the most efficient way of searching through a date-time format. I stopped and just thought that was the most "Reddit"moment I’ve had so far here and it felt nice

Bandcamp is where I do most of my shopping. Not sure where you are located. In Europe, for alternatives I use Qobuz and have used Bleep.
I tend to use it for more “commercial” albums.

I’m currently using beets to tag my music and airsonic for streaming

I’m using airsonic with symfonium, gotta check Gonic (it’s been mentioned twice in the comments)

As others have commented, stick with the Mac.
I recommend installing proxmox on it and run the apps you want. You can run pihole in a VM.
Do you need a NAS? Not really, but if you have cash available maybe get a used tower, use the disks you have and install TrueNAS. And this will only cost you max €200
