  • Great Signal is imperfect.

    Can you suggest a perfect alternative?

    At this point I’m just happy my family have tolerated it to the point we’re not using Facebook Messenger, Google chat (it whatever it’s called this month) and WhatsApp.

    The xmpp or whatever other convoluted alternative you’re about to recommend is not something I’m going to get 20 or 30 family and friends to switch to.

    Signal is imperfect But not as bad as many other options.




  • Sometimes it’s not about typing.

    In the electronics works the us a serial protocol called SPI Serial Peripheral Interface.

    In schematics we might have a micro controller that connects to several sensors or memory chips on a pair of pins, 1 each for transmit and receive.

    The micro controller is the master and the common nomenclature for the pin names is MISO and MOSI MasterInSlaveOut and MasterOutSlaveIn.

    This overcomes confusion with regard to using things like TXD and RXD.

    Wokeness has now suggested a bunch of alternatives.

    PICO PeripheralInControllerOut and POCI are the 2 leading alternatives.

    Problem is I now have data sheets and schematics going back to the 1980s

    It’s bullshit to me.

    Words can have more than one meaning. Context and meaning matter.

    I just want design cool electronics.


  • Yep. There was an assumption 20 years ago when common switches were 100Mbps and running cat5e that you’d have to upgrade cable to get the next speed tier, 1Gbps.

    It propagated wildly, but was always incorrect. Cat5e was very much capable of gigabit Ethernet by design.

    It was only beyond gig that you’d need cat6, and even then at short lengths 2.5/5/10Gbe has a good chance of working on cat5e anyway (but don’t do it).
