Not self hosted, but Tabby is the closest I’ve found. But I still don’t like it as much as Termius. And from what other, more experienced people have said, Tabby is bloated, requiring way more system resources than a terminator emulator app should.
Also, I asked a related question here if you want to read some other suggestions.
Any DE that looks remotely like Windows. My journey to Linux began with a seething hatred of the way Microsoft does pretty much anything. Including the Win10 UI. So when I jumped ship I wanted something completely different. I tried Gnome on a couple distros but ultimately landed on Pop!_OS and really like it!
I ran Pi-hole for years. Switched to adguardhome running on 2 servers (primary and secondary) with AGH sync keeping the two instances identical. I like the UI better, dns rewrites, and the ability to simply block services entirely with a single click.
I haven’t found one that I like as much. My biggest hangup, and this is probably dumb, is the ability to edit the icons for PWAs so they don’t show the stupid browser icon that screams “I’m a web shortcut!!!”. I tried Hermit as a PWA/lite app replacement and Android just slaps the hermit badge on it instead. For whatever reason that annoys me enough to stick with Nova.
I have my Immich library backed up to Backblaze B2 via Duplicacy. That job runs nightly. I also have a secondary sync to Nextcloud running on another server. That said, I need another off prem backup and will likely run a monthly job to my parents house either via manually copying to an external disk then taking it over or setting up a Pi or other low power server and a VPN to do it remotely.
I went with Pop!_OS because it was one of the least Windows-like DEs. Which is what I wanted after getting so damn sick of their garbage. Kinda macOS though with the dock and all. I dig it.
I had a similar need and settled on tasks.org. Depending on your needs, this may not fit. It’s more of a Google/Microsoft tasks replacement. It’s been really nice for my needs.
Obsidian is great, and I agree the sync is too much. It does work flawlessly but Im going to try Syncthing again after my one year is up.
Another newcomer that is promising is Acreom. Doesnt require an account on PC. Currently does on mobile though. But like Obsidian, it is a pile of markdown files. No weird database silliness like Joplin does.
