    I wasn't expecting typed jigsaw puzzle pieces.

    Now we're embedding first-order logic quantifiers in our jigsaw puzzle pieces.

    It's always cute how category theory people use diagrams in logical expressions. Type theorists have executable semantics tools for their type system metalanguage. I wonder if category theorists need an executable semantics for their diagrams.

    There's a closely related property called "causality of a process" that comes up in QM; here's a nice treatment via string diagrams

    The hardest problem in Computer Science is returning memory to the OS when you're done with it. So do allocation in child processes in a long-lived program.

    It is pathetic to copy 6 pages from an obscure paper by two Chinese academics, introduce a pile of mistakes, and pretend like you proved selfish mining was impossible. But it is truly a work of art to plagiarize "hello world" to demonstrate that you know how to program.

    People talk about "pure functions", but what about impure values? Observing my Twitter banner could damn you to an eternity of simulation hell. Copyright violations are another infohazardous material: The same text observed in two ways exposes you to different liabilities.

    Matter is impure because observers remember it as a side effect. Dark matter is better called "pure matter". We see it all around us, but the memories would be a state change.

    Maybe "independent with respect to an observable" is more useful than "pure".

    All computer programs(except for infinite loops) are impure, because they have the side effect of modifying the instruction pointer. So a language for reasoning about purity is vacuous.

    All computer programs are pure functions, because the exposed boolean interface of a CPU is a pure function: clock :: (IO_Pins, Internal_State) -> (IO_Pins, Internal_State) So a language for reasoning about purity is redundant.

    It's not useful for solving symbolic problems like theorem-proving, because those have all the differentiable parts stripped away. However, it is useful for solving differentiable problems like classifying or generation, by attaching or inferring stable logical properties.

    There are two uses of the IF theory: 1. A human operator can predefine relations that should hold. "A dog should have eyes contained within it." 2. The network can automatically infer new relations that hold with high confidence. "Dogs are observed to usually contain eyes"

    I'm generating a neural network architecture from the axioms in an Independence-Friendly Logic. Each one contributes to the error. Variables represent an instance of training data. You can debug the network by seeing which derivable sentences fail to hold under random sampling.

    Religious beliefs are protected despite most being incorrect(they are incompatible with each other). Should other incorrect beliefs have equal protection? Maybe the Flat Earth Society gets a tax exemption, and complains that NASA is a violation of Separation of Church and State

    People opposing universal human rights should have fewer rights.

    Types reduce the possible meanings of an expression. Typeclasses give every syntactic combination of combinators a separate valid meaning.
