You forgot 0 and everything.

Trick TRUE Treat?

Trick FALSE Treat?

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

[–] [email protected] 27 points 2 weeks ago (1 children)

Sure, but what about Trick IMPLIES Treat?

[–] [email protected] 14 points 2 weeks ago (2 children)

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
[–] [email protected] 5 points 2 weeks ago

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.

Add flavoured salts for more variety. I'm partial to Tajin or Montreal Steak Spice.

the whole seeds do taste good but its a bit like chewing up some bits of wood

This is just great

What is xnor and when did that become a thing?

[–] [email protected] 12 points 2 weeks ago* (last edited 2 weeks ago) (3 children)

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.

[–] [email protected] 2 points 2 weeks ago (1 children)

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

so AND. Always AND.

[–] [email protected] 10 points 2 weeks ago* (last edited 2 weeks ago)

My bad. It's "must have both or none"

[–] [email protected] 1 points 2 weeks ago (1 children)

That's the reason I set up Home Assistant. I'm not smart enough for wiring.

[–] [email protected] 7 points 2 weeks ago* (last edited 2 weeks ago) (2 children)

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.

[–] [email protected] 4 points 2 weeks ago (2 children)

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.

[–] [email protected] 1 points 2 weeks ago

"The light won't turn off! Now to hunt down the ONE SWITCH in the house that's flipped...hnngg...."

Troll electricianship would be hilarious entertainment.

[–] [email protected] 1 points 2 weeks ago (1 children)

I have no clue what that means. More diagrams plz?

[–] [email protected] 2 points 2 weeks ago (1 children)
[–] [email protected] 2 points 2 weeks ago (1 children)

Yeah, it does. Thank you! What did You create it with?

[–] [email protected] 2 points 2 weeks ago

Oh I pulled that from Google, I just looked until I found the one that helped me grasp it.

[–] [email protected] 2 points 2 weeks ago (1 children)

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.

[–] [email protected] 3 points 2 weeks ago* (last edited 2 weeks ago) (1 children)

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.

[–] [email protected] 1 points 2 weeks ago

That's at least magic I understand kind of 😅

[–] [email protected] 0 points 2 weeks ago (1 children)

Isn’t that the same as AND but with a lot of extra words?

[–] [email protected] 3 points 2 weeks ago* (last edited 2 weeks ago)

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.

[–] [email protected] 6 points 2 weeks ago

I'm pretty sure that's not exclusive or, as in the not of XOR.

[–] [email protected] 1 points 2 weeks ago

It is essentially an equivalence gate: A==B.

no one else saw halloween boobs in the thumbnail? am I the only pervert on here?
