  • In Australia it depends on whom you ask.

    The Greens say it’s a catastrophe.

    The Labor party says it’s a problem, but not enough of one to actively do anything about.

    The Liberal party tell you what you want to hear, but support the fossil fuel lobby while saying that it’s not manmade.

    The National party wants more nuclear power because apparently it’s “better” … for some reason that nobody understands.

    One Nation blames the immigrants

    The Trumpet of Patriots blame One Nation.

    Fringe dwellers blame COVID, or grasshoppers, or kangaroos … it’s hard to keep track.













  • That you posted in this community means that I am going to assume that you understand that light and radio are the same thing. This means that anything that can “detect” light is essentially an antenna, for that (range of) frequency(ies). The Charge Coupled Device sensors or CCD sensors are in common use in digital imaging, it’s an integrated circuit that can detect light. Or said differently, a CCD can detect radio waves at light frequencies.

    In other words, a CCD chip is an array of antennas, that do what you describe.

    I’m not sure what a densly packed array of nanoscopic antennas brings that isn’t already solved with a CCD.

    CCD’s are also used outside the visible spectrum in all manner of places.









  • Before you start consolidating, consider what might happen if the switch is in an unexpected state. For example, someone turned off the heater or pump and you were expecting it to be on.

    In other words, you need to consider what a “safe state” is for each thing and how your code, when it fails, reverts to that state. This is an example of “failsafe”.

    Note that I said “when it fails”. This is true for all software, even on mission critical systems.
