Related, I was struck by a comment made by the respiratory specialist doctor Martin Tobin, during the George Floyd murder court case. He said less than 10% of smokers actually go on to get 'issues'. He was pushing back on the line that as a smoker, George Floyd was more prone to react badly to 'having a knee on his windpipe...' you know the rest. I did rewind and listen again then look up what he was saying and indee…

For anyone curious, I found the relevant sentence. An astonishingly counterintuitive almost throwaway remark by a world's expert sent me on a deep dive on what else can and does cause lung problems. Dr Martin Tobin says it at 3h 02m 40s... https://www.c-span.org/video/?510467-1/derek-chauvin-trial-d...

What was your takeaway? Any added insights/reading?

Just in case why people are wondering why cutting of internet for an arctic island is a big deal. What many might not know is that Svalbard is home to the northernmost satellite station in the world. It is just one of two stations that can communicate with polar orbiting satellites each day. ESA and NASA as well as other civilian organisations are present there, and the station communicates with well over a hundred s…

Most probably Russia will claim sovereignty over all of the Svalbards after the next big war and redrawing of borders, Stalin was too circumspect in not scaring the Americans into WW3 the first time when they had the chance to do it.

All that because whoever controls the North Pole controls most of the Northern Hemisphere, it’s actually one of the very few “ways in” inside North America and control of the continental United States (there were a few US geopoliticians/geographers who first became aware of that in the early 1940s).

I for one welcome our new Polar Bear Overlords. (Hope the Russians don´t forget their rifles when they move in.)

> I wonder how much data per unit of time this is capable of transporting. The max throughput of fiber optic cables isn't exactly constant. As fiber optic modem and DSP technology improves you can get much higher speeds on 15+ year-old cables than were ever possible when they were laid. Recently I saw an article about researchers getting 300,000 Gbit/s over existing fiber optic cables (though I'm sure that's a long w…

This applies to single-mode cables, but much less to multi-mode cables. Of course long-distance cable like this is always single-mode, but it's worth keeping in mind if building a fiber network inside a building.

Can you use single mode fiber in a house, or do the transceiver only work over much longer distances? Is transceiver burn out an issue?

Radon is scary, and surprisingly everywhere in some regions.

Dave Barry made a similar observation about antismoking PSAs, objecting to one that had someone throw a diseased lung on a table. He pointed out that you could present any random internal organ and it would look just as bad: " This is what will happen to you if you keep smoking. Look! A perfectly healthy goat kidney!"

10% aren’t low odds when it comes to health issues.

You can use SM for short runs, you just have to match the optics to the cable/distance you're looking to use. Tons of very fast single mode optics out there that only expect That said, it's likely not worth it, given that cabling is typically viewed as a ~10 year investment, and if you're installing OM4 Multimode fiber in a house you're not likely to hit the limit of that fiber within 10 years even in extreme use cases.

Russian trawlers going back and forth in that area… https://x.com/PerErikSchulze/status/1794828268480438514

Is that boat trawling directly over the same area where the cables were damaged? Unclear from the tweet alone...

yes – the trawling pattern in the GIF is over (part of) the area marked as damaged in the NRK article: https://www.nrk.no/tromsogfinnmark/this-is-what-the-damaged-...

Had a case in Canada where a fisherman ignored the maps and kept picking up a fibre optic line with their fishing gear, and eventually cut it with a saw (twice): (I suspect it was a short-haul line, so carried no electricity for amplifiers) https://www.canlii.org/en/ca/fct/doc/2011/2011fc494/2011fc49... https://en.wikipedia.org/wiki/Peracomo_Inc_v_TELUS_Communica... > In 2005, however, he managed to pull up the Sunoq…

The idea of being way out on the open water, and pulling up your anchor and finding that it is bringing up some giant steel-wrapped black cable up out into view as you look over the edge of your boat, going off in either direction downward into the seemingly infinite deep water... brings up some crazy weird primal fear [1] in me. I wouldn't even want to touch it, let alone haul the cable onboard and cut it. I'd cut loose the anchor chain and hope to see the thing again.
