  • My guy, you're all over this thread hassling people as if there's only one valid notation. I warned folks about your cocksure confusion of notation and rules two weeks ago, and your oblivious ass did exactly that in response to my warning.

    You're so confused about notation versus rules that you think RPN must have parentheses, somewhere, somehow, because they're in the One True Notation.

    I don't think you understand being wrong, as a concept. Your brain slides right off it and circles back to a sequence of words that lets you be smug.

  • Probably the part where you said how we write expressions is different from the underlying maths.

    Because words mean things.

  • Ohhh, so there is a difference between what's in math(s) books and the underlying laws of reality. When it lets you scold people.

    [Digital Circus] Ep 7: Beach Episode

    Jump

  • Everyone's focused on Kinger saying of Abel - "Who?"

    But the far more worrisome line comes right before that. "Huh? Leave the Circus? How would you-- no, that doesn't make sense..."

    Jax follows up in the Chinese Room: "How would we have gotten hooked up to this big machine just by putting on a headset?"

    The pods are as made-up as the rest. There are no bodies. How would an AI modify a human brain? Everyone here was scanned. There is no out. So far as we know, everyone in the Circus took the headset off, wondered why their brain felt tingly, and walked away.

    Except for Jax and Ribbit. My prediction is that they knew each other, Jax was driving, and an accident left Ribbit basically dead. He pulled some strings to get him scanned while comatose... and then dropped a copy of himself in there, out of some mixture of sheer guilt, a desire to give him company, and the selfish inability to let go. Even through all of Caine's mind-fuckery, he can't let the only remnants of his they-were-roommates friend get deleted.

    My further prediction is that even this is a defensive distortion. It's Jax who was dying, and Ribbit who followed him in. On some level he knows that pushing the blue button would have killed them all, and there's no meatbag copy of him running around 'the macroverse.'

  • It adds them in the background, so that you don’t have to - if it didn’t it would return wrong answers - you not having to type them in doesn’t mean they aren’t getting added

    I don't think you understand mathematics above the 7th-grade level you brag about teaching. No bona fides will excuse how you've acted; you have to be better. On the internet nobody knows you're a dog, and you act like a child cosplaying a teacher that students hate.

    RPN does not have parentheses, any more than standard notation can have a stack. The concept does not exist. Yet both forms of equation are equally valid, but different - in the same way as peasant multiplication versus new-math multiplication. I'm not saying this for your sake because you're a broken robot. But since you're spamming everyone in this two-week-old thread, some of them are going to scroll through wondering 'is this schmuck for real?,' and they deserve to know exactly how small-minded and stubborn you are.

    You're basically out here demanding that multiplication can only be done in the peasant method, so if someone's explaining it without a list of doubled numbers, they 'can't admit they're wrong.' So you're going to henpeck them one line at a time, ignoring the many ways they try to politely explain you're being a pedantic troll, and pounding books that reflect knowledge as if they define knowledge, until they all give up trying to spoon-feed you your own visible failure to teach anyone anything. Nobody's walking away from these interactions like 'oh thanks, good to know, that's perfectly clear now.' It's wall-to-wall 'I don't think you're as smart as you think you are' and 'you're really missing the point' and 'if it always gets the same answer then there's no meaningful difference.'

    Yet tour dogmatism is so blatant that you're assigning Buddha nature to parentheses. Your philosophy cannot comprehend a math notation where you're even merely overreaching, let alone mistaken - so parentheses flit into being, somewhere in a stack operation between two numbers at a time. 1 2 + 3 * is not an equation with parentheses. Order of operations is baked into the order of operands. The first time I explained this to you, you had never heard of it. Yet you immediately asserted you'd found something missed by all all other people, sites, and indeed holy texts maths books.

    You are a crank. Trying to 'no u' about your absence of self-awareness does not work, because you didn't predict me showing up to harass people with grade-school math while not listening. What you're doing is troll behavior. If this is how you teach children, it's enforced learning by rote, and their understanding of even basic mathematics is permanently hobbled by your smile-and-repeat-yourself rhetorical style.

  • Save yourself the trouble - Smartman Apps is a crank. They categorically will not comprehend the difference between the notation we made up and how numbers work. Dingus keeps saying 'animals can count' like that proves parentheses-first is completely different! from distribution.

    Why'd Russel and Whitehead bother with the Principia Mathematica when they could just point to Clever Hans?

  • You are the brickest wall on lemmy. Either out of undiagnosed neurodivergence or some aggravating character gimmick, you pretend there is one true way to do a thing, except when you don't. The commutative property means addition can happen in any order! But multiplication and distribution are totally different (despite getting the same goddamn answer due to the commutative property) and you will never ever shut the fuck up about splitting that hair.

    It's dogma. You've internalized one set of rigid instructions, and declared them the rules of all mathematics, to the point you insist Reverse Polish Notation has parentheses. It fucking doesn't. It literally cannot. Yet it's an equally valid way to write and do math. It gets the same results, despite distribution being impossible. Last time I tried wedging this uneniable fact through any gap in your mortar, you smugly declared you'd found a way... and then explained multiplication, not distribution. Zero self-awareness. To this day, you are trying to be smug about a time you proudly contradicted yourself.

    I feel sorry for students who can't just tell you:

    Go away, patience vampire.

  • Software path-tracing has been on my bucket list, mostly to test a concept: physically based instant radiosity. If an eye-ray goes camera, A, B, C, then the light C->B forms an anisotropic point source. The material at B scatters light from C directly into onscreen geometry. This allows cheating akin to photon mapping, where you assume nearby pixels are also visible to B. Low-frequency lighting should look decent at much less than one sample per pixel.
