The person to blame is the idiot who saw that "1024" was sort of like "1000" and thought corrupting the meaning of "kilo" as a prefix was a good idea. Of course, the rest of us are at fault for not lynching him and letting this state of affairs continue.

I recall my Libra showed 6.7GB available when it was new. It may have been empty or had just a couple of books on it at the time.

Please don't tell me we're still whining about the binary/decimal number discrepancy in 2020. Save that one for your grandkids and tell them how you used to store files on floppy discs, paper tape and punch cards.

Never underestimate the bandwidth of a station wagon filled with reels of tape.

or a concorde filled with 1TB SD cards...

I've considered keeping pigeons. They can certainly beat my broadband, though latency is high and you need parallel copy transmission in case of packet loss to raptors.
They can easily carry micro SD cards. Though first you have to somehow deliver the pigeon to the source of the download.

The big so called "cloud" operators and co-lo data centres do accept HDDs by courier. Fibre is too slow.

1024 is divisible by 16 and 1000 is not. (16 bits is key with hexadecimal)

No, it's purely to do with RAM addressing originally, so called 1K RAM chips, powers of two on address lines, so 1024 bits per chip. Later 4 bit, then 8 bit chips. The storage, being power of two based, tended to double or quadruple on each iteration of chip design.

Nothing to do with hexadecimal, or even octal which used to be popular. Though obviously it's inherent that all the chip sizes are divisible by 16. It's to do with binary. There are 10 kinds of people in the world, the minority that understand binary and the rest.

Are your pigeons going to be RFC 1149 compliant?

No, I'll just strap on the microSD cards, so not TCP/IP or UDP.
Satellite modems actually fake TCP/IP and UDP. They use several protocols depending on supplier and age. So only a VPN provided by a man-in-the-middle and the ground station re-implementing the VPN client works. Usually a specific agreed set up with corporate customers.

The pigeons will really just be customised file transfer, avian sneaker-net. No SFTP, SSH, HTTPS, VPN or VOIP. But file encryption would be advisable. There is a flaw though to the best encryption.

The Evil Maid routine can even work on laptops with an encrypted disk. No spanner needed.

I might be wrong but as far as I understand the differences would be on the physical and link layers but not on higher layers (routing & transport), so both IP and TCP/UDP would be exactly the same.

Or am I missing something?

The geosynchronous ones are 35,786 km above the equator. Actual paths are longer due to the user being north or south of the equator and also often to the east or west of the satellite.
About 1,000–1,400 ms latency for the total round-trip time (RTT). So the conventional protocols don't work properly. I suppose UDP in theory less of a problem.

Out of order packet acknowledgement is used in some schemes, basically a proxy server in the modem:
ONE scheme https://en.wikipedia.org/wiki/Perfor...nhancing_proxy

There are quite a few incompatible systems still in use and staggeringly some are not encrypted! Obviously you need an X37 or spy satellite to monitor the users uplink, unless you are near the ISP Earth Station with a big dish. The downlink to all the users is easily monitored. Snowdon's revelations on the general level of interception were not new.

I expect HTTPS over satellite isn't any more secure than using a public WiFi point with malware on it. Disclaimer. I used to work for an ISP that provided three different kinds of satellite internet while I worked there. I evaluated stuff. We also did cable broadband protocols over terrestrial microwave links. That's very secure, so as to stop people on real cables hacking or getting free service.

If you think a "burner" phone is typical criminal & spy thing, imagine a "burner" satellite internet connection with dish in a shed with a plastic roof. The extra bits for the uplink transmitter (ODU) are obvious compared to a regular TV reception (TVRO). Then imagine that connected to a fake phone mast intercepting and passing on traffic to the real phone mast and the clandestine satellite link. Quite a bug.

That's supposed to be news? The article is from 2015. It's been known since the release of Windows 10 that there will be no Windows 11 or 12.

Personally I don't care. Win 10 is good enough for me.

Sheesh... That article is from 2015. That ain't news, it's olds.
