This page contains our notes about our proposed solar PV installation.

“A little knowledge is a dangerous thing”, so the saying goes. I am no expert on these matters, just technically savvy and curious to learn and understand it all. I’m hot on electrics, physics, geometry, calculation; but weak on the practicalities in this industry. That’s why we’re approaching installers for their expertise in design and installation.

Jellyfin Feature Requests: 26: Add support for two factor authentication: comment 2021-12-10

Yes we need more powerful auth options but no we don’t want each service implementing its own sign-on and security code, we don’t want more user-visible complexity that’s specific to Jellyfin and works differently from our other self-hosted services.

These remedies smell nice and feel […]
