Many great options already but I would like to add filestash to the list. I did not test it out yet but maybe it fits your need.
I am currently arguing what to do with my gaming rig and home theater. Either get a long cable which would need a DP-to-HDMI adapter or get a used mini PC (which is currently cheaper than a Raspberry Pi?) and setup Sunshine and Moonlight (but over WiFi and not LAN) to be more flexible when I eventually move the two into separate rooms. Does anyone have some experience with that? Maybe also latency over wireless network?
I read about silverbullet a few times now. What is your experience with it? It looks very nice but I switch note taking apps so often I don’t have time to use any of them properly.
+1 for dockge. But that’s something for later. Yunohost is a great way to get a feeling for selfhosting.
