If you are interested in really understanding wifi technology, the difference between the various versions, practical considerations, and cutting through all the marketing hype, I’d highly recommend reading this website.

Good question. This new material is technically a ceramic, not a metal, so I’d be inclined to say no. But we’d need more information on its electrical properties to say for sure.

For photos, I have been using Immich, and have been very impressed. It has pretty much all the features I want (automatic backup, chronological timeline, mobile/web app, face tagging, semantic search, albums, sharing, etc). It’s a server you self-host though, so setting it up might be a pain if you’ve never done something like that before.

And a drop in costs too since their system has to support less users.
