      Trick TRUE Treat?

      Trick FALSE Treat?

      I don’t remember what we called those in my intro comp sci class.

      It would be ((trick nor treat) or treat) so basically all the non-circle region and the treat circle is filled…

      After writing this, i am wondering if you actually needed the information or was it just the funny thing to say…

      Guys am I autistic?

        Guys am I autistic?

        Haha might be? But I’m the same way and I’m pretty sure I’m not autistic…(ADHD though)

        I think when you fill that spot between ((“knowledgable”) AND (“good-natured”)), you just like to share what you know if the poster’s sarcasm isn’t painfully apparent.

        Never hurts to be kindly helpful. It reminds me of something my sister told me she tells her kids:

        “Try to learn something new every day, and even if you don’t, teach something.” :)

        I had to double-take since in Python a common alternative to trick ? treat : notreat is (trick and treat) or notreat

        But I don’t think this translates to overlapping circles very well. “trick implies treat” is only defined inside the trick circle, outside is undefined if treat is true or not.

        I’m not going to draw a diagram, but here’s the “truth table” for A implies B:

        A, B, A -> B
        N, N, undefined
        N, Y, undefined
        Y, N, false
        Y, Y, true

          If A is false, A -> B is true regardless of what B is, so the two undefined terms in your truth table should be true.

          So it is fairly easily translated into a shaded Venn Diagram. It’s simply everything shaded aside from Trick only.

    Toasted pumpkin seeds:

    Using running water seperate seeds from pumpkin guts. Soak them in salt water while you carve. Preheat and bake at 220C for 15-20 mins. Eat them whole.

      XNOR (Exclusive NOR) is the opposite of XOR (Exclusive OR)

      A way to remember XOR is “must have one or the other but not both” XNOR is the opposite so it’s “must have both or none” so both inputs must be 1 or 0.

      XNOR or XOR is very common in homes with staircases so that you can turn on and off the light in the staircase regardless of which floor you are on.

      If you google staircase switches, you will be told that they mostly use XOR but according to the wiring diagrams they use XNOR.

        XNOR is the opposite so it’s “must have both”

        so AND. Always AND.

          Wiring a staircase switch is actually very easy, you pretty much just need two wires going from one switch to another and then a light.

          Your light switches also has to be three way switches but afaik most switches in my country are that, so you can pretty much use any switch.

            I was gonna say lol that’s a fancy way of describing three-ways

            Fun fact, you can put as many 4-ways in between those 3-ways as you want, or as many as your electrician will agree to anyway. You can switch the same light from a dozen spots if you really want to.

            I understand it now, but I’ll have it forgotten in five minutes. I’m a software engineer, this here is dark magic to me. Well, not this, but more complicated stuff. I envy you all for your big, juicy brains.

              Oh, I am no electrician. I an IT admin.

              Being an electrician would be pretty high on the list of things to do if I weren’t allowed to work in IT though. Seems fairly fun.

          No, AND won’t match 0,0 while XNOR will. An AND switch would be useless for a staircase.

          AND also won’t match 1,0 or 0,1 while XOR does.
