  • how many ways can you really communicate with a cell tower?

    Analog encoding assigns each device in a cell its own frequency range.

    Time-domain multiplexing assigns each device a fraction of a second to transmit.

    Quadrature phase-shift keying alters the timing of a signal to convey data.

    Orthogonal frequency-division multiplexing has each device transmit the same signal over P out of Q bands, such that each device’s signal can be reconstructed by knowing which bands it transmitted on.

    There’s a fucking reason your phone is faster now than in 2010.












  • In English, distinguishing those two symbols has become an affectation. The straight "" style is all anyone actually types, and it’s unremarkable to see that style rendered or printed.

    The length of a dash is even less important than that. Any style guide that’s insistent about it might as well demand you type movie names in a different font. Can it be done? Sure. Does it have semantic value? Maybe. But the only people who’d care also know how to pronounce LaTeX.

    This is the language that abandoned an entire letter because it was hard to print.
