From Reddit [1] comes Character Encodings For Modern Programmers [2], a facinating look into the history of character sets used by computers. Did you know that some form of electrical communications have existed for about 175 years [3]? Or that time-division multiplexing (multiple messages sliced into segments, sharing a single wire) was done as early as 1873 [4]? That Thomas Edison tried his hand at time-division multiplexing in 1876 [5]? Or that the first serial communication system using bits was designed in 1882 [6]? I didn't.
And we haven't even gotten to character sets yet!
I don't know … I just find this stuff interesting.
