A #Stargate episode got me thinking about how much of our modern technology I could reproduce if I suddenly ended up in a less advanced civilization.

I'd certainly have to reinvent a lot, but I'd probably build a working computer in the end. Out of relays. Because transistors require highly pure silicon and clean rooms, and besides, I just suck at chemistry.

Oh, and if they do have computers already, internet would be very easy to make. It'd be better than ours by skipping IPv4, too.
