Well, yes, but you didn’t, did you.
Come on, it does not take long consideration to appreciate how this can be interesting, even if the technical requirements aren’t interesting in themselves.

Re: A Portal Connecting NYC to Dublin Opens in Flatiron Today
#32I wonder what the latency is going to be on this. It needs to be at least 1/30th of a second round trip but I suspect the actual latency is going to be more like 1s+
Why 1/30th? Latency will be far more than that due to speed of light. My mpeg vision circuits are about 480ms end to end from Washington/New York to London. The j2k ones are faster but still in the 200ms range. In theory you could get it down to sub 100ms but at that point you are certainly having to engineer your paths correctly and use barely any compression. Uncompressed 4k is in the 10gbit range.

1/30th of 1s is almost exactly the round-trip time from NYC to Dublin (Wolfram Alpha says 17ms one-way).

#33Earlier quoted context omitted.
I don't know why it would be any different from a Zoom call. In reality it's probably even faster since neither side is dealing with Wi-Fi.
It doesn't say what technology is used, does it? Could be using wifi, or cell networks.
Wired, using the subsea fiber cables, your still stuck at a 60 ms RTT minimum from NYC to Dublin. Add in video transcoding time and a more realistic estimate of the networks on either side, and you're looking at latency closer to 200-400 ms. WiFi over this distance actually isn't a significant contributor to latency.

#34Super cool! I would love to see a ring of these leading to all different countries. Really interesting way to connect countries together.

I wonder the same. I already take issue with the use of "realtime" in the marketing material.
Would you consider zoom call with someone on the other side of an ocean "realtime"?
If so, I don't see how this is any different. If not, that's a pretty narrow definition of realtime given the context.

OP is correct, 1/30 s is a good ballpark theoretical lower bound.
Assuming travel across the earth surface, light in a vacuum take about 14ms to cross the distances. Times two for round trip that’s about 1/30 s.
Of course we don’t have anywhere near ideal conditions there (at a minimum, light in fiber is already slower, closer to 40ms round trip in that case, and of course network infrastructure adds orders of magnitude), but it’s a good limit.

#37I hope this helps manifest a real portal but yeah JetBlue may disagree (i.e. unmanifest)
That was an ad in the beginning, right?

#38This is neat, I hope one day similar structures are placed in cities around the globe, and it helps ease tension that builds so easily online.
Seriously. Usually the only way we can see images of other places is through media, which may be biased. (Even if the stories are true, the stories which are chosen may not be representative.) This is a really cool opportunity to cut through all of that and just show everyday people.
It would also be really cool if there was some kind of live translation that let people talk to each other in their native languages.

That would be fun. How do you imagine the “ring”? A huge part of the appeal is that both sides can see each other.

Yea...if it's countries with tensions, people will start mooning the portal and worse hahaha
Well, I much prefer people mooning each other, or, similarly, the actual happenstance of countries voting for and against each other in the Eurovision Song Contest for reasons other than musical merit, to armed conflict.
