Haven’t found anything better for note taking. Obsidian was great, but I’m tired of payment issues with Sync, and no, I’m not self-hosting my notes. 

 Private git repo for your notes 

 I write my notes to an NFS share that gets put on all my machines. Nixos is the shit 

 I’m guessing you use Tailscale for remote access? 

 Kernelspace wireguard. I found there were performance tradeoffs with tailscale because it's userspace.
