Meanwhile in place of power, cable, and phone lines there is a related 18 mile translucent line hung in order to turn the entire city into one big happy home called a *eruv* -- following the law of the highest of high courts to the letter. [0] [0] https://www.youtube.com/watch?v=hSldb9IMDVU

I live in nyc, when I first heard of the eruv couldn’t believe they would come up with such elaborate hacks just to ‘technically’ still be following their religious laws! Now if I remember I try and spot it when out.

It also has a status page! https://eruv.nyc/

This is quite informative and useful as I live in NYC. I think in the video he mentioned that the city is collecting all that data on what’s underground to collect all in a database and make repairs easier - anyone know if such data is or will be public, like on data.ny.gov ? And what I’m getting at, is it would be really cool to have this kind of 3d visualization like in the video, but based on actual real data so I could view what’s actually underneath the streets I walk every day.

An illegal tunnel in a densely populated city like that is a bold move.

Here's a video in which a Rabbi who is a member of the sect clarifies the story: https://xcancel.com/Truthtellerftm/status/197901264211193488...

This is a clip from a comedy podcast called 9/11 is Gay.

Pieces of Belgian cities?

If you're referring to the Belgian blocks[1], I don't think they're actually from Belgium specifically, just Europe in general. Although some might be from Belgium!

This is fantastic, but I so hoped it would come with an infographic of NY's underworld, slice of cake style. I recall seeing one somewhere, but my attempts at finding it again all failed.

The video does have something like that, it's not labeled though, rather he goes through each part and highlights the part he's talking about

Somebody posted on HN before about an eruv index, that’s how I found my city had one as well[0]. I assume they got sort of popular around Jewish neighborhoods.

I'd say it was an utterly braindead move and pretty much everyone involved is lucky to be alive.

There's just so, so much dangerous stuff you can hit below ground - high voltage cables that really, really do not like it if you even nick them, high current cables giving off nasty electromagnetic fields, ordinary low voltage cables whose isolation is already degraded, old water, gas, steam and sewer mains that may or may not burst simply because the only thing holding together the rust is the pressure from the soil, other, maybe long forgotten tunnels...

And that's before even getting into the issue of potentially getting caved in, creating a sinkhole or an ingress avenue for stormwater.
