We are at a point in history where the electrical telegraph is well established.

But people don't want to press letters one by one on a switch. They want to talk!

The first phones appear to have used telegraph lines directly.

Also wired phones don't require modulation, which likely made their development much easier than wireless voice transmission. You just send the signal as a voltage differential directly obtained from the air pressure: how the telephone works.

The original gangster.

Some cool ones:

Persistent undo history:

One of the things Ciro Santilli really likes, see: Linux Kernel Module Cheat.

If computational physics simulates physics, emulators simulates computers.

Experiments explained by QED but not by the Dirac equation:

Builds on top of propositional logic, adding notably existential quantification.
