Not all TerraMaster units. I happen to have one that can’t replace the OS.

Every where and any where. They are a mix of PDF and epub.

For me:

• Card/CalDAV baikal : so that I can sync my calendar and address book across phone, tablet, workstation, and laptop
• Messaging prosody/synapse : private chatting with family.
• File sync Nextcloud : for access to various files. This is the only one that has worked consistently for me. Syncthing et al would constantly lose connection and the file I needed wouldn’t be there. Works fantastic for syncing Joplin notes.
• VPN wireguard : to access things remotely and securely
• Audiobooks audiobooksheld : I have a ridiculously large audio book library and enjoy listening to them when driving. This way I don’t have to preload my phone.
• Ebooks calibreweb : another large library. I have separate instances for different types: Magazines, regular books, RPG/gamebooks.
• Version control forgejo : for coding and creative writing projects.
• bookmarks shaarli : I find myself using this less and less. I use Firefox’s built-in sync, so I’m thinking about switching to separating selfhosting that instead of shaarli.
• Photos Synology : looking forward to immich getting stable. Once they get past regular breathing changes I’ll move over to that.

I have stopped using most of the services that got me into selfhosting. Things like rss and wikis. I try new things from time to time but kill them if I don’t find myself using them regularly or if the maintenance cost is more than the value add.

I’m not sure about libre office, but Excel has lookup and lookup. I’ve not personally used those. But might be of help.

I have the same issue. I want something simple but has encryption, native mobile apps for both Android and iOS, and threading. Facebook style posts with comments would be great.

For now we’re using matrix and element bc I can find anything better. Unless something more compelling comes along we’ll probably migrate to something xmpp based like snikket.

Has anyone tried selfhosting ente photos? Curious how well it works.

I hope they really do it. I’d love notes in Thunderbird.

Terra Master has a six bay DAS.
