00:04:33 Snakebird looks like it would make a good esolang, as birds can grow any length, they can stuck and they have great hysteresis, and also one can blow a sleeping bird graphic marker to mean something more 00:06:19 e. g. imagine a nondeterministic machine where birds move in all possible ways to reach a goal or to go through kind of checkpoints 00:07:56 one can encode data in a bird’s form like how many squares does it run between turns 00:10:27 hm this scheme makes addition on ℕ easy: you have a L-shaped bird and you just need it to straighten at the portal 00:14:11 now we need to specify how the bird is placed at the start, e. g. if it’s the tail square that’s fixed in place or the head square, and which orientation the bird is, and also I now see that we can’t add unbounded numbers if we place the snake and the portal both in predetermined places 00:17:48 that’s not all that obvious so maybe I’m wrong 00:25:02 -!- aaaaaa has quit (Ping timeout: 260 seconds). 00:31:08 -!- zeroed has quit (Ping timeout: 260 seconds). 00:32:05 -!- adminn has joined. 00:48:13 -!- aaaaaa has joined. 00:51:50 -!- Lord_of_Life_ has joined. 00:53:08 -!- Lord_of_Life has quit (Ping timeout: 256 seconds). 01:09:13 -!- arseniiv has quit (Ping timeout: 264 seconds). 01:10:25 -!- Cale has quit (Ping timeout: 264 seconds). 01:12:23 -!- Cale has joined. 02:06:57 -!- oren has quit (Ping timeout: 260 seconds). 02:07:10 -!- oren has joined. 02:16:24 -!- oren has quit (Remote host closed the connection). 02:16:38 -!- oren has joined. 02:48:22 [[User talk:TightOnTime]] N https://esolangs.org/w/index.php?oldid=78140 * TightOnTime * (+0) Created blank page 03:28:23 -!- aaaaaa has quit (Quit: leaving). 04:23:49 -!- adu has joined. 04:49:14 I have my doubts about rot7 + {dup drop compose apply apply!} being turing complete. or I just don't see how the construction can be performed. 04:50:49 -!- Sgeo has quit (Read error: Connection reset by peer). 04:51:09 -!- Sgeo has joined. 04:55:10 seeing as you can't push an empty quotation, you would need to duplicate two pieces of data. but duplicating one piece of data means you lose track of another, unrelated combinator. 05:55:10 -!- sprocklem has quit (Ping timeout: 256 seconds). 06:27:38 -!- adu has quit (Quit: adu). 06:32:30 -!- rodgort has quit (Quit: Leaving). 06:43:21 -!- rodgort has joined. 07:05:14 -!- Frater_EST has left. 08:08:46 -!- hendursa1 has joined. 08:10:43 -!- hendursaga has quit (Ping timeout: 240 seconds). 09:03:24 -!- jix has quit (Quit: WeeChat 2.8). 09:08:51 -!- jix has joined. 09:13:05 -!- Sgeo has quit (Read error: Connection reset by peer). 09:13:45 -!- t20kdc has joined. 09:18:17 -!- LKoen has joined. 10:12:08 -!- imode has quit (Ping timeout: 260 seconds). 10:34:13 -!- adminn has changed nick to zeroed. 10:38:14 -!- tromp has quit (Remote host closed the connection). 10:48:17 -!- tromp has joined. 11:02:08 -!- hendursa1 has quit (Remote host closed the connection). 11:03:01 -!- hendursa1 has joined. 11:46:47 -!- user24 has joined. 12:11:52 -!- ais523 has joined. 12:12:15 @message imode if for some reason you need an empty quotation, just compose dup and drop 12:12:15 Maybe you meant: messages messages-loud messages? 12:12:19 @tell imode if for some reason you need an empty quotation, just compose dup and drop 12:12:19 Consider it noted. 12:13:25 a question I've been idly wondering about (that has minor implications for PPCG answers): if I have a matrix where the elements are drawn uniformly from a finite field, is the probability of the matrix being singular exactly 1/n (where n is the number of elements in the field)? 12:13:30 or is it just approximately 1/n? 12:13:55 err, I guess it's called CGCC nowadays 12:14:50 really I need to make a good finite field library, finite fields seem to come up all the time when dealing with anything to do with storing information 12:15:24 -!- laerling has quit (Quit: leaving). 12:15:32 The number of non-singular nxn matrices in GF(q) is q^n-1)*(q^n-q)*...*(q^n-q^(n-1)). So your probability is 1 - (1-1/q)*(1-1/q^2)*...*(1-1/q^n). 12:16:06 hmm, I wonder if that has a simple closed form; probably not, but it looks like it might 12:16:09 (different n, obviously) 12:17:40 I think that is the simple closed form (if you write it as a product) ;-) 12:21:17 the closed form is apparently the q-Pochhammer symbol 12:21:25 which I'm pretty sure I came across recently in another context 12:21:48 in this case, (1/q; 1/q)_n 12:22:44 because the first two arguments are equal, it collapses to the Euler function as n tends to infinity 12:24:11 they come up in partitions a lot 12:29:42 I guess what I'm trying to figure out is, is the probability of being singular likely to be small / invertible likely to be large? 12:31:11 it does look like it, the Euler function has values near 1 when its input is small 12:33:11 OK, and I found a Wolfram Alpha query that explains the behaviour pretty well: https://www.wolframalpha.com/input/?i=minimum+of+QPochhammer%5Bq%5D%2Bq+for+q+in+0+to+1 12:33:45 looks like the probability of being singular is a little more than 1/n, but never by all that much 12:34:12 so in particular, if we just rely on picking a random matrix and hoping it's non-singular (my use case), we'll normally get away with it when the field is large 12:36:57 [[Entfedern]] M https://esolangs.org/w/index.php?diff=78141&oldid=74960 * PythonshellDebugwindow * (+29) /* See also */ See also 13:21:09 -!- hendursa1 has quit (Quit: hendursa1). 13:21:41 -!- hendursaga has joined. 13:33:11 zzo38: I don't understand the context. what is snakebird?

hmm 13:42:24 I mean unless the field is small 13:42:31 for GF(2) the probability is quite small 13:42:45 I guess it depends on which direction you take the limit in 13:42:57 I think for a fixed q, it's always much smaller than 1/n 13:43:05 I mean for a fixed field 13:43:18 oh well, you can ask a more precise questoin if you want 13:45:08 -!- lifthrasiir has quit (Remote host closed the connection). 13:50:16 -!- lifthrasiir has joined. 14:06:40 snakebird is a cool puzzle game 14:06:43 I recommend it! 14:14:42 -!- Lord_of_Life_ has changed nick to Lord_of_Life. 14:14:53 -!- Lord_of_Life has quit (Changing host). 14:14:53 -!- Lord_of_Life has joined. 14:20:23 yeah, it's awesome 14:20:26 i suck at it, though 14:22:35 it's pretty hard 14:24:28 the play store recommended it to me for months and i always looked over it because it looks like a game for children 14:24:31 but boy was i wrong 14:27:55 -!- user24 has quit (Quit: Leaving). 14:37:08 -!- adu has joined. 14:38:06 b_jonas: it seems that the larger the (square) matrix is, the more likely it is to be singular, but the probability tends to a limit of (1/q; 1/q)_n which is slightly larger than 1/q but not by much (especially if q is large) 14:38:16 here, q is the size of the field, n the size of the matrix 14:38:27 so the limit is _∞, _n is for a specific size of matrix 14:42:44 -!- Arcorann_ has quit (Read error: Connection reset by peer). 14:52:04 -!- ais523 has quit (Read error: Connection reset by peer). 14:53:20 -!- ais523 has joined. 14:56:20 ais523: I see 14:57:44 [[]] M https://esolangs.org/w/index.php?diff=78142&oldid=75389 * PythonshellDebugwindow * (+1) /* Commands */ Fix command 14:58:04 [[]] M https://esolangs.org/w/index.php?diff=78143&oldid=78142 * PythonshellDebugwindow * (+10) /* Commands */ Fix commands 14:58:44 [[User:PythonshellDebugwindow/(Unnamed language)]] M https://esolangs.org/w/index.php?diff=78144&oldid=75789 * PythonshellDebugwindow * (+1732) First draft of ++**p; 15:09:52 -!- user24 has joined. 15:48:12 [[Detrovert]] N https://esolangs.org/w/index.php?oldid=78145 * Hakerh400 * (+6701) +[[Detrovert]] 15:48:16 [[Language list]] https://esolangs.org/w/index.php?diff=78146&oldid=78103 * Hakerh400 * (+16) +[[Detrovert]] 15:48:19 [[User:Hakerh400]] https://esolangs.org/w/index.php?diff=78147&oldid=77146 * Hakerh400 * (+16) +[[Detrovert]] 15:56:02 ais523: is that limit proportion zero for q=2 but greater than zero for q=3 ?

=> that wasn’t exactly zzo38 :D Snakebird is a puzzle game in which you are given birds in the form of snakes on a square grid. A bird can usually move in cardinal directions step at a time as a regular snake from the snake game does, but after each step it experiences gravity and may fall on something sharp or out of the map, which means you need to undo. As the regular snake, a bi 18:58:09 rd can block its movement and this means a dead end too. In the game, you need to touch every bird’s head to a portal, and they are sucked into it, presumably to the next level 19:01:57 I’m not finished the game yet, it’s definitely a good level of hard, a bit more than I’m capable of :D agree with myname and rain1 19:06:59 -!- adu has quit (Quit: adu). 19:37:37 -!- imode has joined. 20:14:10 -!- arseniiv has quit (Ping timeout: 256 seconds). 20:19:08 -!- arseniiv has joined. 20:26:58 -!- arseniiv has quit (Ping timeout: 260 seconds). 20:39:54 -!- rain1 has joined. 21:04:45 [[User:PythonshellDebugwindow/(Unnamed language)]] M https://esolangs.org/w/index.php?diff=78148&oldid=78144 * PythonshellDebugwindow * (+165) /* Specification */ Comments 21:52:24 -!- sprocklem has joined. 22:15:32 -!- Arcorann_ has joined. 22:16:05 -!- Arcorann_ has quit (Remote host closed the connection). 22:16:32 -!- Arcorann_ has joined. 22:31:35 [[5D Brainfuck With Multiverse Time Travel]] M https://esolangs.org/w/index.php?diff=78149&oldid=76501 * RocketRace * (+219) Some clarifications regarding backwards time 22:38:45 -!- Lord_of_Life has quit (Read error: Connection reset by peer). 22:39:49 -!- Lord_of_Life has joined. 22:39:50 -!- Lord_of_Life has quit (Changing host). 22:39:50 -!- Lord_of_Life has joined. 23:08:51 -!- joast has joined. 23:11:37 -!- LKoen has quit (Quit: “It’s only logical.
