"just for some stupid trading" is one of the underlying forces beneath the success of all modern economies. Without it almost everything you buy would be more expensive.

Are you considering “having cheaper stuff” actually progress in terms of humanity ?

you've grown so accustomed to modern conveniences that you don't realize that you're kept alive by things that not even a king could've afforded 100 years ago.

Referring to Hoi An, we cannot help but mention the shimmering old town nights in the brilliant lantern festival, especially on the night of Trung Thu full moon. This has become a feature that takes place monthly by the city and makes many tourists stay when having the opportunity to travel to Hoi An. https://privatecartransferhoian.com/hoi-an-lantern-festival/

Because HFT firms can pay for a standard StarLink and get the same results. There are few HFT customers and you have to offer them something that can't get from your consumer service if you want them to pay commensurate to the value provided. Your other points have nothing to do with my HFT specific comment.

"standard StarLink"? StarLink doesn't exist yet, and when it does, it doesn't seem unreasonable to think that two satellite constellation providers could serve the HFT market and both be profitable.

Still totally missing the point. You have to offer something extra to the HFT traders to sell them a $10000/month plan instead of a $49.99 plan. Discriminate on latency somehow for their traffic. Prioritize packets, prefer shortest links over most expedient links, minimize hops. Otherwise if they will just buy your standard plan and you don't monetize them effectively.

Think London to NYC, or NYC to Tokyo. Fiber will be slower. https://youtu.be/QEIUdMiColU?t=196

What I'm saying is that it's faster to just buy a server in NYC.

I don't think you understand what many HFT firms do. They arbitrage between exchanges. For example the option or futures price of a security in Chicago and price of the underlying in New York. Also arbitraging between equities listed on multiple exchanges.

Co-location isn't a solution to these problems, and low latency lines between exchanges in different parts of the country and world is a huge huge factor to successfully implementing many/most HFT strategies.

High speed trading. You can send a packet faster from London to nyc via a LEO network than an underwater fiber.

Why are there people investing so much money on these things, filling up the space, just for some stupid trading. Why is humanity doing this ??

Would you pick up a $20 bill on the ground?

I think we all know the answer to that question, and if you know the answer to that question, you know the answer to your question:

To make fucking money (of course).

Maybe it's time to talk about tech-free preserves established by international treaties. E.g.: sections of each continent and ocean can be declared tech free where modern technology is forbidden on earth,sea or land. This is so we don't lose and forget the nature that forged the present.

Maybe we should each decide what we want to forget or not forget.

I am looking forward to when Huawei put up their global network... Charge zero for the uplink devices if you buy the first 6 months up front using bitcoin. With free Huaflix and sports channels (unlicenced, use at consumers own risk).

you are going to need to order straight from china though

I've been wondering about remote cell towers as well. When I'm out in rural areas I'll regularly get 'LTE', but my downloads will be considerably slower than when I'm in a city (despite a much lower population density). My assumption is that it's very expensive to get highspeed internet out to these locations. This should enable cell phone companies to place a tower as long as they can run power to it (and solar pane…

In a lot of rural areas the cell towers are linked together using some sort of wireless tech, usually microwave links or similar line of sight technology. So in effect all those towers share their Internet bandwidth.

It's not likely this. Microwave transport is fast. The real difference in rural sites is a combination of spectrum (ie. 5mz of 850) vs 20mhz of 1700/2100.

850 has better propagation, hence its usage in rural.

The other factor is antenna patterns and site sectors. Many rural sites have an omni antenna, and with no tilt.

In cities you may see 6+ sectors on a site with 12 degree tilts. So your site has more bandwidth(20+ mhz), and way more capacity.

Long story short.. They give you less of the interwebs in rural because it's cheaper

At what point should we start worrying about Kessler Syndrome? > The Kessler syndrome (also called the Kessler effect,[1][2] collisional cascading or ablation cascade), proposed by the NASA scientist Donald J. Kessler in 1978, is a scenario in which the density of objects in low Earth orbit (LEO) is high enough that collisions between objects could cause a cascade in which each collision generates space debris that i…

The bigger issue is all these satellites outnumbering the total number stars visible from Earth. It has astronomers worried. https://www.nytimes.com/2019/06/01/science/starlink-spacex-a...

Astronomy is fine and all but I think this is more important.
