Nice list! Btw draw.io is not optimized for mind maping. For mind maping I use Freeplane and realy like it.

Kodi multimedia center.

I use it and love it, but still think the logo is a bit weird, reminds me of some evil message you see after a virus crashed your PC 😁.

It's trillan you are talking about. I am old too :D

Hope more will follow.

Restic, a reliable backup solution.

Not as powerful as Tasker, but for some basic automation tasks PhoneProfilesPlus is a good alternative.

I bet soon more airlines will follow. Our cars are no different either. No much options left for traveling.

Have a link?

No longer maintained.

Joplin maybe?

Not sure, maybe "diagramming". Btw there is a good alternative to draw.io for self-hosting called Excalidraw. Very easy to set up with docker.

This is a good starting point if you want to dive in.

I usually put all the relevant travel data in my Joplin notebook. If the tickets are availible as .passkey files I manage them with PassAndroid. Transportr for public transportation. Wireguard if you need to access your home network via VPN.

Not sure about the self-host part but Jabref and Zotero might fit.

Using Argon NEO and quite like it. In my case it was important to have the ability to use a HAT (HiFiBerry).

What are the reasons for the Pi Hole to Adguatd switch?

Nothing wrong with WG Tunnel. Btw Wireguard is on the IzzyOnDroid Repo.

Cannot find canvass on f-droid, got a link?

There is a curated list of links for german audiobooks: tarnkappe.
