Workshops 1 & 2 — Infrastructure 101, then the Commune Information Node. By noon you have a local hub that serves without internet, a network people can join to reach it, and a node that comes back on its own after you pull its power out.
Sharing the room: Build a Cyberdeck is in this same call until 15:00. Your scheduled window ends at 12:00, but you're welcome to stay — and the block right after lunch is the last item on this workshop's minimum goal. Their companion is here.
Times drift. These blocks are deliberately coarse. Trust what Liz says over what this page says.
