    the amount of cooling you get is proportional to the difference of component temperature to ambient temperature. thats why modern chips are engineered to run much hotter.

    Actors tend to lead to bloated incomprehensible code. Even when you do want game objects to look like independent message passing actors. Faking it is always easier. Actors are sel…

    think of corrugated metal. sound waves and heat will travel slower in the wavy direction than in the straight direction. you can stamp some more complicated pattern onto a piece of…

    > Nobody knows how even the current generation of LLMs work (at the plumbing layer, sure, but the high-level behavior is a complete mystery). i dont think thats fair to say tbh. cl…

    the jacobi identity is [x,[y,z]] - [[x,y],z] = [y,[x,z]] ie. it says the lie (pronounced "lee") bracket is almost associative but you have to add a [y,[x,z]] when you rearrange bra…

    both of these are reasonable. if you have an `x` such that `x + n = x` implies that `n = 0`. (assuming x still has an additive inverse) in other words you just invented modular ari…

    Your mixing up terms. immediate mode rendering and immediate mode gui are unrelated. immediate mode gui libraries generally dont use immediate mode rendering because its realy slow…

    thats how it works. its called a swapchain and its usually more than one texture. to avoid artifacts.

    you can use (abuse?) multiplication to get a nice dither without any tables: bool dither(int time, int value) { time *= value; return (value + time ^ value ^ time) where value is i…

    thats pretty much it yes. the reason they dont just say 2nd derivative is that the derivative isnt a geometry property. you can have two curves with the same shape but different de…

    the right solution is to parametrize the search region as (offset, length) instead of (start, end). then the midpoint is just offset+length/2. you can also remove that unpredictabl…

    regular photogrammetry usually means searching for common features in a bunch of photos. if you find the same feature in 3 photos you can triangulate its location in 3d space. the …
