@whitequark there are too many people on fedi, who would, to exactly pin down who you mean

There was a Xen vulnerability (VM escape) a few (10?) years ago that was a result of a bug in floppy disk emulation. It required urgent patching on most clouds, even though they don’t actually expose a way to use floppy disks. As I recall, this all existed because some Windows versions failed to boot if they couldn’t find a floppy drive.

@david_chisnall i remember that!

@whitequark@social.treehouse.systems Casual reminder floppies stopped production more than 15 years ago (but really 19 years ago, February 2007).
Good riddance, substandard 1.4mb storage devices lacking any and all error correction. -

i had an idea to use Glasgow to write a one-packet-per-track, properly ECC'd and encoded data, with significantly higher density. but i never finished it

@whitequark@social.treehouse.systems I, along with 3 other people, had ideas about recording Opus to regular cassette tapes via QAM and using RaptorQ for FEC.
Glad I never bought that heavy tape deck now. One less thing to carry or throw away. -

@whitequark@social.treehouse.systems My original plan was to use AC bias (~15khz constant sine to remove wow and flutter digitally), and 8b/10b on a lower frequency for the data.
@td@pars.ee made a demo using gnuradio with QAM, and later someone did the same, and I have no interest in the actual signalling, just in the error correction and Opus. So I was happy to have them deal with it.
There's enough pure beauty in error correction algorithms to satisfy me. Accurate on encoding, inaccurate in decoding is the exact opposite of audio codecs. -
