(www.adiirc.com)). 03:04:48 so if you want that ability, you have to find a balanced home for it 03:17:53 Maybe, but it has entwine, and and I can think of uses for the second ability, so it isn't entirely useless. (Split second alone, as well as madness alone, can both be useful and I have puzzles where that is the important part.) Other possibility can be to add other stuff such as cycling. But, what you suggest is another possibility, but I don't know what balanced home to find for it. 03:19:48 zzo38: split second on a spell is useful, but adding it to a spell with another instant is much less useful, because you can respond to this instant 03:20:23 -!- delta23 has joined. 03:23:52 Yes, but if you apply it to the object on the bottom, then it prevents casting other spells in between.

(The idea where this comes up is when performing a move... you can figure out which stones to turn over with a ripple carry trick, but only in 4 out of the 8 directions. With bswap it's 7 out of 8; a full reversal would make it... 14:00:12 ...work for all directions.) 14:03:22 [[Zirconium]] https://esolangs.org/w/index.php?diff=82495&oldid=82494 * RocketRace * (+1400) Restructure the page, increase cohesity, add golfing utilities ;) 14:07:26 int-e: I'll also mention http://software.schmorp.de/pkg/libecb.html , which has some bit manipulation functions, including find first and find last bit set, popcount, bit reversal (for full integers), and byteswap. I have touched these, because I contributed some code specifically about the bit ops, and I've used the byteswap multiple times. 14:09:02 plus you probably know about the two relevant books. Henry S. Warren, Jr, "Hacker's Delight" second edition, it's not perfect and uses rather odd notation that annoys me in a lot of places, but it's a hard to replace book, you won't find any other with this many details, so I put up with it 14:09:09 the other is TAOCP vol 4 14:09:12 fwiw, https://int-e.eu/~bf3/tmp/reversi.cc is the (slightly horrible) code I have. I have not tried to make it configurable and I've only targeted i7-6850K because that's what I have at home. 14:09:29 b_jonas: But yes, I do enjoy bit hacks a lot. 14:10:14 Warren's book is also somewhat obsolete, it doesn't really consider tricks that are specific to the SIMD operations of x86 SSE2 and later x86 extensions 14:10:19 (not sure whether there's anything interesting in that code; you can enjoy the magic constants at least) 14:10:24 but even so it's useful 14:10:45 This might benefit from SSE2 stuff but I don't have the stomach for it :P 14:10:58 I can help a bit with the SSE2 stuff 14:11:04 (It's not like I actually *need* this for anything.) 14:11:04 if you have specific questions that is 14:11:08 I ahve worked with it 14:11:14 yes yes, #esoteric and all 14:11:46 I have touched SSE2 a little bit in the past, but it was never enjoyable. 14:13:54 I also have the feeling that Oscar Toledo of the IOCCC fame might know a lot about bit tricks, but his code is very opaque so I don't think there's any way to *learn* those tricks from him 14:13:58 The code is in an odd spot for the target processor. For example, I have some unpredictable conditional jumps and eliminating them makes the code... the same speed, more or less. 14:14:46 I could replace the 64x64bit multiplication by shifts... but intel's multiplier is too good 14:14:51 stuff like that 14:15:32 sure, the multiplication and float multiplication instructions are good on x86, you should use them 14:16:48 there are a lot of different multiplication instructions, including four different ones that multiply vectors of 16-bit integers, I've used some of those once 14:17:04 they're useful for pixel images 14:17:22 -!- LKoen has quit (Remote host closed the connection). 14:18:04 pixel images were a key motivation... all the way back to MMX, and even 3DNow! 14:18:39 int-e: I don't see where you use 64-bit multiplication other than by constants here 14:18:55 multiplication by constants is rarely worth to replace, because compilers can already optimize them when it's worth 14:19:11 especially for unsigned 14:19:14 b_jonas: x*UINT64_C(0x0102040810204080) stuff 14:19:19 yes, that's by constants 14:19:32 if that can be optimized, the compiler will optimize it 14:19:35 b_jonas: it doesn't matter, it uses the usual 64 bit integer multiplication 14:19:56 it may be worth to replace a signed multiplication by an unsigned one to help such an optimization, but you're already doing unsigned 14:20:00 *I* knmow that x is a power of 2; the compiler doesn't. 14:20:03 it's rarely worth to replace it by shifts 14:20:08 oh 14:20:11 x is a power of 2 14:20:19 ok, that's trickier 14:20:38 and I could compute the shift instead of the number further outside in the code 14:20:55 using ctz instead of the x & -x bit trick 14:21:03 yes, you could 14:21:06 I tried it, it made the code marginally slower 14:21:21 I don't know if it's worth because I don't know what your code does and what its bottlenecks are 14:21:25 and I probably won't try to understand it 14:21:38 can you tell the goal of this code though? 14:21:44 what does it try to compute? 14:21:51 the state of a reversi board after a move? 14:21:57 b_jonas: I wrote it to find shortest Reversi and Othello games 14:22:33 And then I went off a tangent trying to speed up the code even though it already ran in a few seconds. 14:23:43 For fun really; an AI would spend most of its time in evaluation functions, no point in shaving off a few more cycles in the move generation part. 14:24:22 makes sense 14:26:05 I mostly did experimented with SSE2 stuff for pixel images 14:26:22 learned a bit about SSE2 and the later instruction set, as well as some existing libraries 14:26:37 that makes a lot more sense too, you have a clear per-pixel operation and immediate payoffs in terms of parallelism 14:26:43 I might be able to use some of that for a future job 14:27:55 though I do have to be careful not to do something so similar to the previous job where I learned about this that it gets too close to stealing 14:29:32 sometimes I also wonder if I should try to make a quasi-esoteric or toy array language that's optimized for image processing 14:30:53 but that probably won't happen 14:32:52 mostly because if I do want to work on esoteric languages, I' 14:32:59 ll probably work on Consumer Society first 14:34:25 -!- MDude has joined. 14:34:59 Hmmm.
