- Gregg shorthand.
- Labanotation (like music scores, but for dance)
- Morse code
- Punched tickets (not for machines, but for train tickets and bus transfers)
- Railroad car chalk markings (where does this car go?)
- Hand signals for railroad yards, cranes, etc.
- OgsyedIE 10mo agoJust gonna jump in here with three more: - Telegraph brevity codes (e.g. Bentley, Marconi) - Telex codes and various predecessors to ASCII (plus even what Telex hardware looks like in a lot of cases) - Heraldry
- doom2 10mo ago> - Morse code I would argue that Morse code is not only alive and well in the amateur radio hobby but actively being adopted by younger people both in and out of the hobby. I just got a holiday card from a college friend whose 6 year old has taken an interest in Morse code despite knowing nothing about the existence of amateur radio.
- lucyjojo 10mo agoham radio license holders in japan: 1994 ~1.3M 2025 340k (lots of old people) and they dropped morse code from the exam requirements in 2011.
- doom2 10mo agoOk? Just because there has been a drop in the number of licensees and the exam no longer requires Morse code wouldn't necessarily put Morse on a list of "methods of transferring information we may have lost historically that we don't even recognize". At least in the US, ham radio is far from a dying hobby and Morse code is actively being learned by people of all ages.
