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?

You're probably thinking of 'The "Only" Coke Machine on the Internet' https://www.cs.cmu.edu/~coke/history_long.txt

I was at CMU '83 to '87. It saved us time to check if there was the proper kind of coke in the machine and if it was cold before we walked down to the room with the machine. It was cheaper than the University's vending machines. And it was in classy glass bottles.

Trivia: It was (I was told) using experimental 3Mbps Ethernet, the predecessor to the 10Mbps Ethernet that has grown to 10Gpbs+ now.

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…

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

At 170MByte/s that's another 100 minutes to get the data off a 1 TB microSD card using a Sandisk proprietary reader. You would need 64 of them working in parallel.

Considering I learnt this week bees have been shown to understand numerical symbols to the point of accociating them with quantity, using bees might be getting a little too close to Turing Complete for my liking. I mean, we all know how badly that turned out with PDFs, right? https://news.ycombinator.com/item?id=20103292

PDFs are not Turing complete (PostScript is).

I knew about postcript (who doesn't lock up office printers by rendering mandlebrot sents?) but was absolutely convinced PDFs were as well. They're not and it seems they quite deliberately weren't as well. [1] - thanks for setting me straight :)

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…

I had an occasion 20-ish years ago to deliver a few DLT tape drives and a bunch of cartridges to a Customer. Before I left we calculated the capacity of a 1995 Geo Metro as a unit of backup media, and the effective throughput from our shop to the Customer at various driving speeds in bits-per-second. It was an odd trip thinking about my speed in Mbps. Today, or course, it would be a Chevy Spark stuffed with micro-SD…

EvanAnderson: Hello Officer what the problem?

Cop: I clocked you at 532 Mbps, this is a 400Mbps zone.

EvanAnderson: Oh I didn't see the sign.

Cop: License and registration.

Actually, you can have Javascript in PDF nowadays, so...
