You should see a link inside obtainium itself, when you press “add app”. Just press on “crowdsourced…”

The programs listed there are the harder ones to setup correctly for obtainium, so you should primarily use that, and if the app isn’t there, then paste the github link / fdroid link / etc like you would normally in add app.

The app for updating is obtainium. Highly recommend it.

Raspberry Pi I’m not sure if it’s worth it. But in short you can advance some science with spare CPU hours. Should be possible to limit it so it doesn’t heat up and use just a bit of the cycles depending on other load…

Cool nick! But it could be even better!

What they should be imagining instead is a better video sharing platform. There are alternatives already…

Good open source alternative: Fossify calendar or Etar with Davx5
