Reminds me of this - predating AI

As early as 1860, experienced telegraph operators realized they could actually recognize each individual by everyone's unique tapping rhythm. To the trained ear, the soft tip-tap of every operator could be as recognizable as the spoken voice of a family member.
- myself248 4y agoOh yeah, every ham knows you can recognize the sending fist. If they're actually using a real key, anyway.
- flak48 4y agoThis made my Google the etymology of 'ham-fisted' and I was disappointed that it had nothing to do with ham operators with carpal tunnel syndrome.
- mzi 4y agoIt's the opposite, really. The radio term was a pejorative, as the professionals saw the amateurs as ham-fisted.
- Victerius 4y agoI don't understand your sentence.
- wbl 4y agoHey's saying if you are using a straight key instead of an iambic keyer (different morse sending tech) then you can recognize the operator from their patterns (the first)
- dd82 4y agohttps://en.wikipedia.org/wiki/Telegraph_key#Operators'_%22fist%22 https://en.wikipedia.org/wiki/Telegraph_key#Operators'_%22fi... > With straight keys, side-swipers, and, to an extent, bugs, each and every telegrapher has their own unique style or rhythm pattern when transmitting a message. An operator's style is known as their "fist". > Since every fist is unique, other telegraphers can usually identify the individual telegrapher transmitting a particular message. This had a huge significance during the first and second World Wars, since the on-board telegrapher's "fist" could be used to track individual ships and submarines, and for traffic analysis.

- nextlevelwizard 4y agoI remember playing FPS game called Enemy Territory as teenager and after awhile whenever I was in 1v1 shoot out with one of my “clan” members I knew who it was based on their movement.
- sitkack 4y agoI was walking down the street a couple years ago, in my peripheral vision I noticed the gait of someone walking across the street traveling the other direction, instant recall of that former coworkers name from 10 years previous. It would have taken longer to recognize them visually if they were standing still. Still amazes me, years later.
- erk__ 4y agoOff topic, but if it was Wolfenstein ET I will just add that there still is a community for it and a Foss version of it that runs on modern operating systems https://www.etlegacy.com/ https://www.etlegacy.com/
- mattr47 4y agoMy Dad was a morse intercept operator for the US Army, mid 60s, stationed in Northern Japan. He has stories of them naming all the Soviet morse operators by the way the tapped.
- Rodeoclash 4y agoCryptonomicon mentions this as well. Each operator having a particular "fist" that was unique to them.
- Aloha 4y agoIt's still true now in ham radio, even for those using a bug (vibroplex keyer) or even an electronic keyer, will still leak some of their natural fist thru.
