    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)

u/kan_9

So you mean the egg came first?
u/katkip

hehe
u/pavel

Isn't it obvious that the egg came first? Chickens evolved. The first chicken had non-chicken parents. This chicken hatched from a chicken egg... because it was its egg.
u/tomxor

lol, settled by semantics... so where does the chicken begin and it's progenitor end? and is that conveniently by definition when hard shelled eggs appeared.
u/pavel

What do you intend to mean by dismissing what I said as semantics? It would be true that the chicken came first if chickens were the first of their lineage to hatch from eggs but being birds i doubt that is the case.
u/pavel

Err, if they were first to _lay_ eggs, without hatching from one.
u/pavel

Point is, the egg is finalized as far as I know. Whichever example was the first chicken, by whatever definition, even if two people cant agree on a definition, that first chicken hatched from its egg and so a chicken egg came first.
u/tomxor

🤣 don't worry man, it's literally the chicken and egg problem
u/KilledByAPixel

Evolution is very gradual, new species (chicken) don't pop into existence. This can't happen because it would need to mate to procreate. Therefore there is no such thing as "first chicken", so the question itself makes no sense.
u/pavel

'Chicken' is an arbitrary human label, these can pop in. Why can't the second chicken come from non-chicken parents too? Also, we dont need a 'first chicken.' There was a time when we had no chickens, all chickens come from chicken eggs, therefore chicken eggs came first.

#LargerThanLife #Automata Bugs Rule

Show more comments…
u/tomxor

The Larger Than Life "Bugs" rule R5,C0,M1,S34..58,B34..45,NM. You can introduce more entropy by adding spaces to the code (to restart) which causes i&1 to be combined with existing state in the rule's dead space.
u/tomxor

This uses a sliding window to efficiently compute the sum of arbitrary radi Moore neighbourhoods (i.e box blur kernels). It naturally wraps to the next line giving it a kind of twisted toroidal space, which takes less code and is more efficient since it is only necessary to initialise the sliding window once per dimension: O(2n+2r). The FPS is half of what is displayed since every other frame is used to sum the transposed sum of x.
u/tomxor

Other sized w must be a power of 2 and i must be at least w**2+r+1 (r=neighbourhood radius) to allow the sliding window to correctly initialise, otherwise a bad sum will propagate throughout the grid usually causing everything to die.
u/KilledByAPixel

👍 Thanks for the explanation!
u/tomxor

hmm the larger than necessary i seems to be introducing artifacts... change to i=w*w+6 if you want to see the pure rule.
u/katkip

Woow! I remember it from the The Powder Toy game
