Hello, IT. Have you tried turning it off and on again?

    Under the same logic, All problems are also caused by turning it off and on again.

    A novice was trying to fix a broken Lisp machine by turning the power off and on.

    Knight, seeing what the student was doing, spoke sternly: “You cannot fix a machine by just power-cycling it with no understanding of what is going wrong.”

    Knight turned the machine off and on.

    The machine worked.

    Turning it off and on again is a universal truth. A defibrillator works by turning the heart off then on again.

    (You don’t defib a patient who is flat lining. You defib to fix an erratic heart beat.)

      ECT basically does that too but for brains. Too sad and Prozac isn’t fixing it? We’re gonna put you under and slap the reset button every other day until you’re not. Shit works too its fucking wild.

      Maybe I’m misremembering (or it’s just old knowledge and new chips are more sophisticated) but despite it being low voltage vs high voltage the outcome is still on or off because there’s a resistor in the semiconductor that either allows current through or not. If it were a light switch it would be the equivalent of turning the light on or off.

      And yet I still have electronics to this day that require me to pull the plug to get going again 😂

        Our LG washing machine does this once every year and a half almost like clockwork. It will simply refuse to do anything until it is unplugged and then plugged back in.

          It may be clockwork. If its power hasn’t been interrupted in the interim, i.e. you have very stable power at your house, that’s got to be some kind of overflow bug in its software. A timer somewhere is running out of room to count clock ticks and it barfs.

          I’ve an oven which when turned off in hot state while in convection mode will turn on the fans for few minutes next time I turn it on, regardless of mode and temperature. To overcome this bug I need to put mains power off for couple of minutes and let the caps keeping the ram alive drain. Not only it has hot state reset bug but also a ram initialization issue as well it seems. Thankfully that state is not stored in nvram.

          The manufacturer was as expected: ‘we’re not software guy, we can send an ‘expert’ engineer (who knows only to replace parts, no debugging) and it’ll cost $$’. I thought I’ll reverse it and fixing someday, till then I’ll live with it.

    Studied computer science. The answer is yes.

    A computer is a funky thingy that’s a jumbled city of stuff turning on and off with the one master on/off thingy which is the clock on the processor.

    When it switches from negative to positive a lot of small switches everywhere switch, some stay the same, some flip. It’s all just a bunch of rythm dancing of switches going off and on.

      If you used mechanical switches, would it be possible to build a large version of some modern semiconductor chip? If so, I would expect that contraption to be slower and louder than the original.

        If you’re willing to sacrifice the clock speed it’s possible. One of the issues will be that the insane amount of logic gates would have to propagate through every cycle which happens stupid fast on modern chips. Still possible to model it and do a timelapse.

          This is pretty cool. I don’t care how slow it is. It just shows that that it can be done. If you want something useful, use silicon. If you want something awesome, use creative alternatives like pneumatic pipes and valves. :D

      Until some stray gamma ray hits just the right spot, flips a bit and either nothing at all of everything all at once happens.

      I come from the net. Through systems, peoples and cities to this place: Mainframe. My format: Guardian; to mend and defend. To defend my new-found friends, their hopes and dreams. To defend them from their enemies. They say the user lives outside the net and inputs games for pleasure. No one knows for sure, but I intend to find out.

    “Since words can be represented in binary, thus as a sequence of ones and zeroes, […], doesn’t that mean that all questions can be answered by saying no, then yes again at some level?”

    How has no one pointed out yet that this is conceptually wrong? Turning something off & on again is cycling the same switch. Solutions to IT problems are setting different bits, which is binary for “using different words”.

      How dare you use logic on my computer logic-related shower thought.

      But yeah, I get what you mean. I had that thought at some point after posting. This is why I should probably just keep it in this silly thread and not write any philosophy essays soon.

      I mean, technically speaking, it’s cycling all the switches. You use one main switch to simplify the process, but it controls all the other switches as well.

        No, that’s the whole misconception here. cycling a switch means returning to the previous state. Turning it off and on again means going from ON -> OFF -> ON. Software problems are solved by going from one state to a different state.

          Software problems are solved by going from one state to a different state.

          Or by moving to Canada.

      Digital means that it’s discrete compared to analog which is continuous. Some of the first digital computers were decimal, but in general binary is simpler to use so that’s why it’s everywhere.
