00:45:26 <fizzie> Re AoC, I got that z is obviously a stack by "disassembling" the program -- https://0x0.st/orNt.txt -- but didn't really figure out how that gives a quick solution since it seemed at first glance there'd be any number of ways to arrange there to be enough pops. Didn't notice that (in my notation) `z%26 + A == D` is only possible for some of the steps.

16:24:36 <fizzie> I didn't want to stop, so I did a bitwise thing for day 25, and it's more than ten times faster than the bytewise one.
16:24:38 <fizzie> It packs 16 sea cucumbers in an uint32, and uses the obvious &s, |s, ^s and shifts to build masks of which sea cucumbers move and which stay in place. With a lot of really ugly code to handle the wraparound when the width isn't a multiple of 16.

20:26:53 <fizzie> What it does is basically, represents >.v with 012, then does a pairwise (JRT...Z[) thing that produces {1 0} for any ">." and {x 1} for anything else, does tp^prt?* to produce the next state, uses 2j?-tp to swap 0/2 and rows/columns for the other half-step, and then just iterates until the result stops changing.
20:27:00 <fizzie> Runs at about one step per second for the 137x137 puzzle input, so takes around 7-8 minutes. But it's the journey, not the destination, right?
20:27:26 -!- Everything has joined.
20:28:49 <fizzie> Actually, now it's just 4.5 minutes, I used to do 012 for .>v and then I had to do 3j?-3?/3?*?- to swap 1/2 because there's no ?% builtin. Looks like it got quite a bit faster after changing that.
20:29:07 <riv> That is really quite something to see
20:31:30 <fizzie> Replaced CLL[2.- (collect stack, get length, subtract 2) by CL~-L[ (collect stack, drop first and last elements, get length) to save one more character.

21:27:27 <int-e> fizzie: sounds not too different from https://paste.debian.net/1224759/
21:27:49 <int-e> (I like `transpose` for CA types of things... well, as long as they don't have to be fast)
21:28:03 <int-e> 2D CA, of course
21:29:38 <fizzie> Switched to {J3ug1!={~]1+]}if<-}Z[ from {J3ug1=={<-}j{~]1[+}jie}Z[ to safe a few more characters. And yes, quite similar.
21:31:40 <fizzie> Although you kind of have the ">." case both consume and produce two characters; I didn't have a convenient way of "skipping" the empty space so I instead made every pair produce two output values.
21:35:16 <fizzie> Hmm, I can shave off one more by changing 1!={...}if into -.{...}if -- didn't try it at first because Burlesque's kind of weird with what counts as "true"; looks like `if` is one of those where anything that doesn't equal 0 is true, but there's some others that accept only 1 as true.
21:35:57 <int-e> fizzie: yeah I assumed the similarity would disappear once we get into the details of that `line`.
21:36:29 <int-e> because Burlesque doesn't really have convenient recursion (from what I've seen).
21:37:42 <fizzie> Yeah. You can define new builtins that recurse with %XY={...XY...} but it costs 6 characters, and conditionals are pretty expensive too.
21:39:09 <fizzie> `if` is better than `ie` (if-else) in that `if` accepts both "<number> <block>" and "<block> <number>" order on stack, while `ie` insists on having "<true-block> <false-block> <number>" (top on right), which is usually exactly the wrong order, so it ends up being `{...}j{...}jie`.
21:39:11 <HackEso> if`? No such file or directory

21:43:10 <fizzie> I don't like it when I have to write {{...}m[}m[ to map over a block-of-blocks elementwise, but ln{{">.v"jFi}m[}m[ still outperforms something like {">.v\n"jFi}m[{3};; by one. And the numeric trickery on 0/1/2 seems to be a win over trying to keep it as characters.
