+# Ideas
+
+I'd really like to find an active speaker that has a built-in DAC with USB-C input and power over that same USB connection.
+
+The only one I've ever found like this is the Bose Revolve. It's old (discontinued?), and uses micro-USB.
+
+This would allow a "sweetheart" setup where the speaker could be plugged up to
+a [Radxa Zero](https://arace.tech/products/radxa-zero-3w) which itself only has
+one USB-C cable for power.
+
+That would make for a pretty nice Snapcast client setup.

+# Home Network Backups
+
+Most of the self-hosted stuff on our network is backed up regularly, as well as both of our laptops and my desktop.
+
+### Linux hosts
+ZFS snapshots are created on host systems that support it (dev, molly, verin) and snapshots are replicated to siuan (backup server).
+
+### Maggie's Laptop
+Maggie's laptop is backed up using Kopia on a regular basis, first to verin then replicated to siuan via ZFS snapshots and also uploaded to Backblaze (using Kopia)
+
+### verin (primary server host)
+All services on verin are backed up using ZFS snapshots and replicated to siuan.
+Home-Assistant also takes nightly backups of its configuration and those are placed in its services folder - which is snapshotted and backed up to siuan.
+
+### siuan (primary backup host)
+siuan doesn't do much interesting besides pull ZFS snapshots from other hosts.
+
+### moiraine (router)
+Regular backups aren't taken on moiraine right now.
