This reminds me of the old saying "never under estimate the through-put of a station wagon full of hard drives". It looks like it has disappeared from the internet but at one time someone had a calculator where you could enter the number of hard drives your station wagon could hold, the size of the hard drives and the time it took to drive across town from data center A to data center B and would tell you what bandwi…

This is still true in astronomy. Data between radio telescopes for VLBI or the EHT is shipped in disk packs. I am not sure how Ice cube gets their data back from antartika, but I don't think it is over the thin and expensive satellite internet. Data from the gamma ray telescopes HESS and Magic are transported to their data centers on tapes.

Earlier quoted context omitted.

I seem to remember that the old saying comes from Tanenbaum's "Operating Systems Design and Implementation". Or not?

Ahhh, you are correct. Thanks!

Another gem from back when the internet was fun: HTTP Status 418: I'm a teapot - https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/418 Wasn't there also a protocol for checking vending machines for cold drinks?

npm implemented it in their server last year!

Considering we actually have internet connected teapots now, I wonder if any mass market products have implemented this.

IIRC Ultimaker 3D printers do implement this

Well, at least sending data via flash-cards and pigeons isn't a joke.

"If 16 homing pigeons are given eight 512 GB SD cards each, and take an hour to reach their destination, the throughput of the transfer would be 145.6 Gbit/s, excluding transfer to and from the SD cards."

Today we have 1TB microSD cards, they only weight an 8th of an SD card.

If the capacity of a pigeon is 8 SD cards (1290,24cm³) then it can carry 64 microSD cards (1049,6cm³).

This means the capacity is now 64TB instead of 4TB. and the throughput would be 18,6 Tbit/s.

Our team got hit by that issue. I slapped by head when I saw the error code, having come across it before. How am I meant to debug something that's literally a joke and isn't meant to be used in production :(

I think you should include the time to copy the data to the SD cards as a 1Tb copy is significant time.

Here, an up-vote for you good Sir.
