An Apple airtag probably doesn't but it is apparently possible to send some data at a very low rate (the article in [1] says a few bits per hour) over the find my network [2]
Nice you could choose if you would like your gasoline with or without service
Still possible in some places. Especially cities with large numbers of retirees.
I used a full-service optional Shell station in Las Vegas last year. Unlike when I was young, full-service didn't mean in increase in the price of gas.
There are a few full-service stations around where I live. But you really don't need your oil checked when you get gas so unless the objective is to have someone else pump your gas in crappy weather there's not a not of point.
I very much liked reading his "computer related risks" book (multiple times...) more than 25 years ago and after that the RISKS Digest was one of my weekly "go to" for a very long time.
Not only the System/390.
Its also IBM i, AIX, and for many protocols the network byte order.
AFAIK the binary data in JPG (1) and Java Class [2] files a re big endian.
And if you write down a hexadecimal number as 0x12345678 you are writing big-endian.
(1) for JPG for embedded TIFF metadata which can have both.
The endianness of file formats and handwriting is irrelevant when it comes to deciding whether your code should support running on big-endian CPUs.
The only question that matters: Do your customers / users want to run it on big-endian hardware? And for 99% of programmers, the answer is no, because their customers have never knowingly been in the same room as a big-endian CPU.
Saying that (hand)writing is irrelevant is a bit of a strawman implying I said writing hexadecimal numbers big-endian on paper matters for coding.
The second sentence, weather your customers know if they have been in the same room with a big-endian system (CPU alone doesn't matter) is irrelevant when the point is to write correct code. Many of then aren't interested in this or other details and that is ok as they are not responsible for the implementation.
Changing the endianness either direction did have show bugs to me several times, that could be fixed, and it was worth it for that alone.
It's always interesting to see how are things build in the Lumafields "Scan of the month". The the most interesting scan from Lumafield I saw was not a Scan of the month, but in "Adam Savage’s Tested: Surprising Flaws in 18650 Lithium-Ion Batteries" [1]
