As a tourist applying for USA visa waiver they wanted social media username/links. But they only had slots for Facebook, twitter, Instagram and LinkedIn. Apparently fediverse hasn't hit their radar.

They had smart folk that understood structural engineering. Kings hired the smart architect / engineer types to build castles on sides of mountains etc. While school is formalized and standardized now, people just as smart existed back then and understood beams, cantilevers, flying buttresses, arches etc
You can refine uranium for power. Prior to trump breaking deals the Iranians had very low potent uranium. Mostly made up of 3.25 refinement. USA had dropped sanctions in agreement for not processing uranium past 20%. That was fine till trump got in power and broke the deal. Then they started refinement up to 60%. So there could be potential to further refine uranium over 90% purity to make weapons, but the amount they had was tiny, till trump fucked the deal
I agree, I lived in a quadplex before, it took up one normal sized residential lot. Great use of space citywise, but also design wise inside it was well thought out. 2 units faced the main street, 2 units faced the backyard garage/alley. From the outside it just looks like one home with 2 front doors, either side. Owners have to agree on roof repair and things like siding replacement, but other than that it was separate living.
Heh 😀
