I need an ais. 03:52:09 @tell 03:52:09 Who should I tell? 03:52:52 * oerjan puts on ais mask 03:53:25 @tell ais523 Do you happen to know about the paradoxical construction where you have a program with arrays, and you simulate it without arrays by recursive calls to the main program whenever you want to read an array element? Is that construction possible and can you point to some writeup about it? 03:53:25 Consider it noted. 03:53:51 I have never heard of such a thing. 03:55:01 you can simulate a read-only array with a function, but that's not recursion. 03:57:38 It seems paradoxical because you're simulating a RAM machine by a stack machine, which is supposed to be impossible. You're not just stacking a whole array into a single bignum, you only have individual array elements on the stack or registers. 03:58:01 i suppose you can give the main program an extra parameter that says "keep track of this element of this array, and return what's in it at this point in time" 03:58:11 *some extra parameters 03:58:38 It doesn't actually contradict the theory because you need a timer variable to know when to break out of each recursive simulation, that timer variable has to have at least as many values as many times the simulated program reads array elements, and you have such time variables on the stack. 03:58:59 The runtime may blow up exponentially, and the stack may blow up to as big as the simulated runtime. 04:00:25 oerjan: yes, in each level of the simulation, you keep track of the array index, the time when you have to stop, the arguments of the main function, and the current time. Only the last one changes within a simulation level, but you can have lots of nested simulations. 04:01:00 i can see the current time growing exponentially, so you need a bignum for it. 04:01:04 Time means how many times you have read array elements during the simulated program (although it can be more refined than that). 04:01:21 oerjan: no, you only keep track of the time of the original program, it only blows up as much as the runtime of that one. 04:01:49 well ok if you assume the runtime of that cannot be too high... 04:01:51 The runtime of the simulation can blow up exponentially, but a time variable only stores the time in the runtime of the original program. 04:03:06 And you can have at most as many levels of simulation as the original runtime, the new stack can have as many frames as the old stack times the number of nested simulation levels, and there's a constant number of timer variables in each level of the new stack. 04:03:51 Each new stack frame stores only a constant number of array elements (the one corresponding to the index you're interested about), but together the stack may hold a whole array. 04:04:45 I'd like to know either why the whole construction fails, or a reference to existing documentation of this construction, and I hope ais523 can provide it. 04:04:56 okay 04:06:03 oerjan: but yes, in the original program you might only need integers as large as the size of arrays (you can imagine this as 16-bit or 32-bit integers if you wish), while the timers may need larger integers (if runtime is more than about 2**16 or 2**32). 04:06:28 The runtime can be exponential in the amount of memory the program uses of course. 04:06:44 Did any of this make sense? 04:09:42 So if the runtime is really about as big as the number of possible memory states, then the timer has to be as big as the number of possible memory states too. But you rarely see such a long runtime in practice. 04:10:54 So practical programs with short runtimes can be simulated with a short enough time variable, but then the simulation isn't practical because it can still take time exponential in the original runtime, and it will do so if the original uses random access in an essential way. 04:11:44 mhm 04:12:34 (Guess why the whole thing came up now.) 04:16:52 -!- sleffy has quit (Ping timeout: 246 seconds). 04:18:18 -!- sleffy has joined. 04:46:45 no idea 05:08:33 -!- hppavilion[1] has quit (Ping timeout: 248 seconds). 05:10:01 -!- doesthiswork has quit (Quit: Leaving.). 05:10:29 -!- doesthiswork has joined. 05:17:41 -!- tswett has quit (Ping timeout: 240 seconds). 05:27:13 -!- doesthiswork1 has joined. 05:27:13 -!- doesthiswork has quit (Read error: Connection reset by peer). 05:32:02 Just now in vim I tried ":spl /dev/null" and surely enough it does work just as well as I expected it to do. 05:37:22 -!- doesthiswork1 has quit (Quit: Leaving.). 05:55:50 -!- oerjan has quit (Quit: Nite). 06:02:35 -!- fizzie has joined. 06:03:22 -!- Lymia has joined. 06:03:37 -!- ocharles has joined. 06:04:24 -!- sparr has joined. 06:05:07 -!- GeekDude has joined. 06:05:37 -!- mtve has quit (Ping timeout: 260 seconds). 06:06:40 -!- mtve has joined. 06:39:18 -!- erkin has joined. 06:56:18 -!- ski has joined. 07:07:10 -!- FreeFull has quit. 07:15:41 -!- propumpkin has joined. 07:18:09 -!- contrapumpkin has quit (Ping timeout: 248 seconds). 07:22:46 -!- Warrigal has quit (Quit: No Ping reply in 180 seconds.). 07:22:54 -!- Warrigal has joined. 07:24:08 -!- hppavilion[1] has joined. 07:35:57 -!- imode has quit (Ping timeout: 240 seconds). 07:36:48 -!- sebbu2 has quit (Ping timeout: 240 seconds). 08:10:37 -!- augur has quit (Remote host closed the connection). 08:13:21 SUBLEQ 08:13:27 http://gerigeri.uw.hu/DawnOS/index.html 08:13:40 Uh.

I've ran the executable at the build dir to test 10:16:44 the good news is that there's no kernel panic anymore 10:16:57 the bad news is that I lied. There's still a kernel panic, now there's a different one though 10:17:04 Does it complain about the init? 10:17:08 yes 10:17:11 10:09 kurolox: If you're getting an "can't execute init" kernel panic, check that the umlbox-linux and init binaries have the same arch (e.g. via "file umlbox-linux", "file init"). 10:17:15 Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000100 10:17:40 okay, will do 10:17:51 Well, that's slightly different than what I'd expect from the "mismatched architectures" problem. 10:17:51 Ah, this may not be the most helpful behavior. "rootfs image is not initramfs (junk in compressed archive); looks like an initrd" 10:18:20 (but you've progressed beyond this anyway) 10:18:27 Here's the log again, I feel like it's not an init problem 10:18:41 https://ghostbin.com/paste/bk3uu 10:18:53 No, it clearly did manage to run init. 10:19:05 (That's what prints the "UMLBox starting" line.) 10:19:47 Think the kernel panic is just because that's how umlbox stops when it encounters problems. 10:20:03 The "mount(source, rtarget, type, 0, data): Device or resource busy" thing might be more relevant, but I'm not sure what's up with that. 10:20:28 now it looks like a missing root fs? I mean, "/bin/sh could not be executed" 10:21:04 int-e: It's not supposed to have that on the root fs, actually. :) 10:21:42 "init" is the only file that's supposed to be on /, the rest it gets by read-only-mounting the host's /bin et al. using UML's hostfs. 10:22:27 Or, more exactly, it mounts the directories out of ["/usr", "/bin", "/sbin", "/lib", "/lib32", "/lib64", "/etc/alternatives", "/dev"] that exist on the host. 10:22:50 That said, it should still have a /bin/sh that way. 10:23:06 why is it mounting proc,sys,tmp twice? 10:23:17 sorry 10:23:19 I think it's my fault 10:23:23 I didn't use the -B flag 10:23:52 now it doesn't panic, but it seems like there are still problems 10:24:11 or maybe it just takes a while to load 10:24:25 int-e: It's mounting them twice because the mount lines are there several times in the configuration file, but I don't know why *that* is. 10:24:47 The "Read configuration" section dumps out what it's got, and it looks like it's repeated three times, which doesn't sound normal. 10:25:34 https://ghostbin.com/paste/rwuw9 10:25:38 umlbox is stuck like this 10:25:43 I assume that it should give me a bash prompt 10:26:25 You might not be able to get interactive use out of the stdin/stdout thing. 10:26:32 Have you tried typing in commands anyway? 10:27:03 Also try something like umlbox -v -B /bin/echo foo to check if a non-interactive command works out right. 10:27:04 yes, but I can't see anything 10:27:32 Also I can't stop the process with ctrl+c, I have to kill it 10:30:00 -!- kurolox has quit (Remote host closed the connection). 10:30:21 Fun fact: for me, "umlbox -B echo foo" outputs just "foo" as expected, but "umlbox -v -B echo foo" (verbose mode) manages to leave terminal echo disabled. 10:31:22 Huh, I do get a working interactive bash prompt out of "umlbox -B bash". Wasn't expecting that. 10:32:13 -!- kurolox has joined. 10:32:28 Sorry 10:32:29 I had to reboot 10:32:40 int-e: Heh, this is a new one for me: "cat: -: Resource temporarily unavailable" 10:33:00 fizzie, about the echo foo 10:33:19 it doesn't work, but I think that is because of how I had to kill the last process 10:33:39 https://ghostbin.com/paste/hkd5s 10:35:05 kurolox: There's something odd going on with the configuration file reading with your kernel, I don't know what. 10:36:16 If you compare the "Configuration" dump from line 3 onwards with the "Read configuration" one from line 90 on, the latter seems to oddly repeat the beginning half of the config. 10:37:25 The length of the "Read configuration" dump for you is exactly 512 bytes, as well. I wonder if, in later kernels, the ubd implementation has changed to e.g. pad files up to a block boundary. 10:37:37 yeah, about the lenght of the read 10:37:39 I've noticed something 10:37:56 I've tried running the commaand in my other computer, and it seems like it just gets cut 10:38:23 https://ghostbin.com/paste/pkqet 10:38:29 $ moun 10:38:29 Unrecognized command moun 10:38:48 that was mount before 10:39:12 It should end at the "run user ..." line, like it does in the outside-UML configuration dump. 10:39:45 On your other box it probably truncates at "moun" instead of "mount" because the gid is 100 in one, 1000 in the other, and 1000 takes up one character more of space. 10:40:37 Well, so any idea? Should i try an older kernel? 10:41:13 If it's what I think it is, you might be able to fix it by padding the config file with 0s up to a block boundary. 10:42:03 Maybe try changing the line in "umlbox" that says conff.write(confs) to something like conff.write(confs + "\0" * (512 - len(confs) % 512)) 10:43:39 (Though I'm a little puzzled moony didn't encounter this issue, if it's some change in udb semantics in later kernels.) 10:44:47 well 10:44:49 it did something 10:45:51 https://ghostbin.com/paste/op8u3 10:46:00 I still don't see the echo anywhere, but there are no errors 10:46:50 Can you check what happens if you try without the "-v" flag? The verbose mode terminal handling is kind of... odd. 10:47:06 (Of course you don't get any logs so chances are it'll just print nothing.) 10:47:10 there's no output 10:47:33 also, I should mention that umlbox always mess up the console formatting 10:47:51 after running umlbox through ssh for example, the cursor is static and nothing I write will be visible 10:48:05 It does that for me as well, though only with -v. 10:48:07 in my desktop everything I type seems to be tabbed over and over 10:48:14 Running "reset" seems to fix it. 10:48:25 okay, good to know 10:48:32 http://sprunge.us/NJRC is what I get out. 10:48:57 Looks pretty similar except I have an extra "ttyraw" in the generated config. 10:49:26 Okay, so this is weird 10:49:34 I've tried to run bash again 10:49:56 so the cursor is static and everything is invisible, but it seems to recognize what I'm doing 10:50:17 as in, I can't see any "echo" or anything, but typing "exit" closes umlbox properly 10:50:32 so maybe it's working but I can't see it, I don't know 10:50:35 Yeah, I'm guessing this is all something to do with the consoles. 10:50:50 maybe it's because I'm doing it through ssh 10:50:54 I'll check in my desktop 10:50:57 Out of curiosity, what do you get if you try "umlbox -B echo foo | cat" (so that the output's not a tty)? 10:51:34 Nothing 10:53:09 Also, there's no difference in my desktop. Same stuff happens. 10:55:15 Well, I'm somewhat stumped. I do think it's highly likely it's got something to do with either the UML console configuration, or umlbox-mudem. 10:55:22 But I'll have to head to work now. 10:55:45 Sure thing.

Got SIGABRT, dying...). 20:21:12 I was up a bit irregularly. I'll be up more from September 20:21:48 re your lambdabot question, you can do a lot of functional tricks to simulate arrays, but recursively calling main isn't enough by itself because you only get one stack 20:22:10 ais523: that's why it's paradoxical 20:22:15 -!- Phantom_Hoover has joined. 20:22:16 which means you're limited to PDA levels of power 20:22:16 -!- ais523 has quit (Remote host closed the connection). 20:22:26 -!- ais523 has joined. 20:22:29 one stack isn't enough if the stack symbols are from a fixed size alphabet 20:23:33 if you have no temporaries, it IIRC isn't enough even if you have an infinitely large alphabet, unless the set of operations you allow on top-of-stack is Turing-complete even on just a single number 20:23:51 you know the easiest way around is to encode a whole array into a bignum. this construction doesn't do that, it's more sneaky, but it still needs numbers as large as the runtime of the original (simulated) program, which in turn can be exponentially large in the memory size of the original program in worst case 20:24:07 like, I think a bignum stack, increment, decrement, push, pop, conditional goto is not Turing-complete 20:24:42 in a functional language, you can implement an array as a function from the index to the element 20:24:50 and assign to the array by wrapping it with more functions 20:24:57 that's a different construction, but a fairly fun one 20:25:15 I have written down the construction more technically in http://www.madore.org/cgi-bin/comment.pl/showcomments?href=http%3a%2f%2fwww.madore.org%2f~david%2fweblog%2f2017-08.html%23d.2017-08-18.2460#comment-23792 , where it applies to the uncomputable esolang (1) and (3), but you can take just the Turing case 20:25:42 ais523: it doesn't just use increment and decrement, but also equal-compare of bignums 20:25:52 and copying of bignums 20:25:58 the natural number cases of (0) and (1) are just bloop and floop respectively, aren't they? 20:26:11 (0) is definitely bloop 20:26:15 wob_jonas: what are you comparing or copying them too? 20:26:16 um, how does floop work again? 20:26:28 it's like bloop except it has infinite loops with break 20:26:31 you're copying a bignum from one stack entry (near the top) to another stack entry (near the top) 20:26:33 for(;;) { … break … } 20:26:48 or you're equal-comparing two bignums in two stack entries near the top 20:27:11 wob_jonas: ah right, which is clearly TC as you can use the top two stack entries as a minsky machine 20:27:13 and you still need increment and constants 20:27:24 at that point, how you simulate things is just a matter of programming 20:27:44 ok, but "just a matter of programming" is somewhat vague 20:28:03 right 20:28:13 I guess this is more a question about programming techniques than about what's possible? 20:28:38 if you have these operations, then you can also implement arithmetic (in exponential time) and store a whole array in a bignum, which is how the minsky construction works (if you have at least three bignums) 20:28:40 perhaps it'd be interesting to try to constrain a language in such a way that you have to program it like that 20:29:05 also, the minsky construction works with two bignums by using one of them to store a simulated tuple of three bignums 20:29:09 which is really slow, but oh well :-) 20:29:21 but I'm still asking about this specific construction, which is a bit strange, because you really don't need integers larger than the runtime of the original program in the particular case simulated 20:29:25 I decided to put my half-finished toy neural net thing on Github: https://github.com/Taneb/net/blob/master/Main.hs 20:29:58 wob_jonas: you might need a write up of exactly how the construction works, then, because I haven't seen it 20:30:17 incidentally, how many languages do we have which are TC only because they can use the call stack as one stack and an explicit data stack as another? 20:30:27 it's a construction which feels like it should be more common than it actually is 20:30:30 anyway, in this case David describes in the original blog article that the straightforward construction where you encode an array in a bignum does work in a finite case, 20:30:51 but also that it doesn't work in the infinite case, and how simulating arrays in the infinite case is VERY difficult 20:30:59 (at least in general) 20:32:04 "TC only because they can use the call stack as one stack and an explicit data stack as another" => I don't recall any such language 20:32:40 wob_jonas, Underload is one 20:32:54 Taneb: no, Underload has complex stack elements 20:32:57 but it rarely comes up, because you'd either need an actual infinite stack for TC-ness, or if you want a practical language, then just two stacks are very impractical for general purpose programming 20:33:00 which means you have more than two stacks 20:33:08 ais523, oh! I misunderstood the construction used 20:33:13 you can think of it as a language in which the stacks are made out of other stacks 20:33:17 oh 20:33:33 actually that language I have imagined but haven't yet documented might be like this, 20:33:44 at least two stacks is the only way I can prove TC-ness, 20:34:44 even though there's a much better practical construction for random access of vast but possibly not infinite memory, where the accessible memory size grows at least double exponential in the code size, probably even faster than that 20:34:58 so you don't really need the two stacks construction for TCness 20:35:19 (although you have to use the stacks at least a little for temporary values) 20:35:39 I will have to eventually document that language 20:37:13 with a data stack, a control stack, and a heap, you may get a G machine. 20:37:41 -!- ais523 has quit. 20:37:51 -!- ais523 has joined. 20:38:12 -!- augur has joined. 20:38:35 that reminds me of my attempt to write a language that's theoretically Turing-incomplete but can access so much storage that that basically never comes up except in programs that bruteforce for counterexamples 20:38:42 Funny, I've obviously never looked at the original G machine paper. It was intended to be an actual hardware design by the looks of it. 20:39:26 Oh well, 1985. 20:42:21 -!- augur has quit (Ping timeout: 240 seconds). 20:44:33 -!- sleffy has quit (Ping timeout: 248 seconds). 20:47:21 -!- imode has quit (Ping timeout: 252 seconds). 20:47:25 ais523: if you have an ordinary computer with a CPU with a 48-bit physical address space, and have a disk interface that gets commands from a memory-mapped variable sized control block, and the sector address and sector size and count of sectors are in that command block, does that work for this? 20:47:41 you can access something like 2**2**48 bytes of memory, give or take a few 20:47:53 wob_jonas: if that's all you have, it's clearly sub-TC 20:48:05 because it's a finite (even if very large) amount of memory 20:48:20 my language was going to make heavy use of the Ackermann function, so it could access way more memory than that 20:48:32 (but still a finite amount for any given program) 20:49:56 wob_jonas: well you can stack the construction. Use half of each address space for data, and the other half for some MMIO interface to the next level in the hierarchy 20:50:04 isn't sub-TC what you asked for? "theoretically Turing-incomplete" 20:50:22 wob_jonas: and then you get something that may be TC. 20:50:36 but fiendishly difficult to implement ;-) 20:50:53 wob_jonas: yes 20:50:59 but I wanted to be closer to TC than that 20:51:00 or you want much more than 2**2**48 bytes? 20:51:02 ok 20:51:15 like, the language scaled with the size of the problem 20:51:38 I think part of the hope was to be able to express any number that humans are capable of describing without resorting to diagonalization tricks, and know for a fact exists 20:52:26 the sort of number which can't be calculated by most Turing-incomplete languages is "the first counterexample to the Riemann hypothesis" (you can't set an appropriate memory limit in advance because you don't know how large it is) but we don't know for certain it exists 20:53:08 [wiki] [[ResPlicate]] https://esolangs.org/w/index.php?diff=52921&oldid=45669 * BlackCap * (+713) 20:53:50 ais523: in that case my language *might* actually work, if you restrict the size of one of the two stacks. I think an ackermann construction for accessing memory in many hierarchies might be possible to implement, but I'm not sure yet, I'm only sure of at least double exponential. But I also can't prove that it can't still random-access infinite me 20:53:51 mory with a fixed code. 20:54:25 (I mean double exponential or ackermann in the code size.) 20:54:33 ais523: The Calculus of Construction should get you quite far. 20:54:40 the largest numbers we can describe are basically modifications of the "the smallest number not nameable in…" trick, only programmatically rigorous 20:55:25 "express any number that humans are capable of describing without resorting to diagonalization tricks" => wait, which humans? if you take the right humans, that's a very very very very very large number, much larger than I can imagine 20:56:29 [wiki] [[ResPlicate]] https://esolangs.org/w/index.php?diff=52922&oldid=52921 * BlackCap * (+107) 20:56:38 wob_jonas: there are some pretty insane humans out there :-) 20:56:48 but I was thinking more of the set of humans that actually exist and name numbers 20:57:03 rather than the set of all hypothetical humans who might want to name large numbers 20:57:09 all this reminds me of http://djm.cc/bignum-results.txt 20:59:03 no, I mean if you take numbers whose descriptions only like ten mathematicians in the world understand, then you get numbers much larger than the numbers I can describe, even with a no-diagonization restriction 20:59:51 numbers I can actually imagine using go to only tetration size like 2***(2**512) or something, but I can describe bigger ones 21:00:33 but if you take numbers that a million humans can describe, those aren't so big that I can't imagine them 21:00:43 int-e: there's a similar thread on PPCG but the rules are really screwed up 21:00:47 all these about humans who live today 21:00:51 and there are debates on whether the rules should be fixed or not 21:01:19 not fixed as in you freeze those rules and start a separate thread with better rules? 21:03:22 there are debates on how to fix it, too 21:03:34 anyway, you might be interested about the non-computable (0) language family that David described, he mentions a lot of interesting details 21:03:37 as in, start a new thread, change the rules of the existing thread, or something else? 21:04:01 . o O ( diagonalize over the thread ) 21:06:15 int-e: that other contest has a rule for exactly that, it says a new guess counts as better than an older guess only if the number it names is significantly bigger than that older guess. so just adding one to a previous guess isn't enough, and "significantly bigger" is very loose. 21:06:39 so you have to use very different techniques than any previous answer to get the biggest number so far 21:06:45 no, I mean to get the best answer so far 21:08:14 wob_jonas: looks like it's still broken: https://codegolf.stackexchange.com/questions/18028/largest-number-printable 21:08:43 the ban on multiplication, in particular, is highly arbitrary 21:08:46 -!- imode has joined. 21:09:45 a ban on multiplication?

21:19:30 such languages exist, e.g. Retina 21:19:35 which prints 1 upon running the empty program 21:20:18 (actually, it prints the number of characters in stdin + 1, but PPCG normally assumes that stdin is empty) 21:21:50 Commodore 64 boots to saying " **** COMMODORE 64 BASIC V2 ****\n\n 64K RAM SYSTEM 38911 BYTES FREE\n\nREADY.\n" does that count as printing 38911 as the largest number? or even 65536 because the 64K clearly stands for that in that context? 21:22:59 I could have told you once, I think? but now I'm happier not needing PPCG rules memorised :-) 21:23:13 anyway, away for a bit, I need to go buy food before the shops shut 21:23:17 yeah, I know, it doesn't really matter 21:26:22 -!- AnotherTest_ has joined. 21:27:44 -!- AnotherTest has quit (Ping timeout: 255 seconds). 21:27:44 -!- AnotherTest_ has changed nick to AnotherTest. 21:31:12 ed doesn't work, it prints the size of its input file if you give the filename as the command-line argument.

21:35:09 classic error message 21:36:41 hey, help me google a thing 21:36:51 months ago i found a paper on arxiv 21:36:59 http://www.smbc-comics.com/comic/dying-wish => wait, just one season? 21:37:09 it was about a new theoretic model that was more cache aware 21:37:27 izabera: oh, that already sounds easier than what I asked. the paper you're looking for probably exists, the one I asked might not. 21:37:57 several algorithms have a different runtime in that model, for instance heap sort is O(n log^2 n) 21:38:36 wob_jonas: I've gone 10 months since installation and no ed. 21:38:43 but not as cache-aware as a six-tape Turing machine, right? 21:39:10 i'll ask somewhere else 21:41:38 Is log^2 n supposed to mean log(n)^2 or log(log(n))? 21:41:45 I guess it's the former, but that's pretty confusing. 21:42:06 shachaf: (log n)^2 21:43:35 shachaf: the former 21:44:08 it's very rare to write log log n as log^2 n, because that would be too confusing. people rather write up to four iterations of log explicitly, and use other notations when they really need to write positive number of iterations 21:44:19 and you rarely need more than four iterations of log 21:44:40 unless you're in log* n territory 21:45:04 (just log log log log does appear in that stupidly specific limit distribution theorem) 21:45:13 or perhaps you're saying that it'll be essentially constant anyway... 21:45:30 just like that \alpha from Tarjan's analysis of disjoint set forests 21:46:17 Tell me when you have an algorithm that takes inverse busy beaver time. 21:47:17 hah 21:47:29 that would be fun 21:48:31 but I really don't see how that would happen 21:59:15 back, but not for long 21:59:21 I might be properly back in a few hours (not sure yet) 21:59:40 ok 21:59:54 -!- LKoen has joined. 22:00:16 btw, something that came up in one of the NetHack channels and I thought "b_jonas might know this": is there a mythological or famous fictional creature that's noted for being afraid of the dark? 22:00:44 afraid of the dark... hmm let me think 22:02:27 well, humans are sometimes portrayed as being afraid of darkness 22:03:01 and... how dark do you want or for how long? there's a few ridiculous photosynthetizing humanoids that know they can't live in the dark for more than a few days 22:03:50 -!- LKoen has quit (Ping timeout: 240 seconds). 22:03:52 wob_jonas: we basically (for gameplay reasons) wanted a powerful monster that wouldn't enter corridors, and I thought being afraid of the dark would be a good way to explain that (corridors are normally unlit, so "won't enter dark squares" and "won't enter corridors" have sufficient gameplay similiarity) 22:04:18 and there's something about shades or shadows, but that probably wasn't being afraid as such 22:04:29 I guess you could have a monster that's powered by light somehow? it seems like the sort of thing that Doctor Who would have, although I can't offhand think of a monster from there that actually is 22:04:50 ais523: wouldn't enter corridors... you can just have monsters that are too big or afraid of narrow tunnels or afraid of being surrounded for strategic reasons 22:05:20 "too big" is an obvious thought but it doesn' really work in NetHack, which has single-square dragons 22:05:38 anyway, I'd better go, thought I'd just throw this out there first in case it inspired you to think of something "in the background" 22:06:01 bye everyone 22:06:04 something that behaves like a human child intellectually could be afraid of the dark, but that works better for an ally than for a normally hostile creature 22:06:18 -!- ais523 has quit (Quit: bye). 22:07:51 perhaps an animal that was once captured in a cage and REALLY didn't like that might be afraid of tight spaces so much that he usually remains far from even walls 22:08:17 and of course nh already have stationary monsters that aren't generated in corridors 22:10:42 I think the olist monster in the dark is afraid of the dark. 22:12:47 too big isn't impossible in nethack, it's just either hard to implement (a long worm like creature that takes up say four tiles forming a square) or hard to flavor (a one-tile monster bigger than even krakens and elder dragons) 22:18:02 if you can implement four-tile creatures, then you could change some dragons to elder dragons. you can then turn the quest dragons to be that large, they both have a suitable map. 22:18:13 (krakens could also be big, but they already don't go to corridors) 22:18:45 you can also find other very big creatures in mythology and fiction 22:22:11 -!- imode has quit (Ping timeout: 255 seconds). 22:29:25 So, besides fizzie and gregor nobody here knows about UMLBox, right?

'umlbox -B -v echo DEADBEEF' doesnt work with the error of https://ptpb.pw/Evrs, yet my bot's sandbox works as if nothing is wrong. 22:34:00 well I do see it echo DEADBEEF halfway through 22:35:40 yeah, so it seems like moony kernel panic happens after the sandbox program sucessfully runs 22:35:44 that might explain why it works 22:46:50 Well fizzie, I'm quite sure the conff issue you helped me with before isn't related to my actual issue of stuff not running on UMLBox, since moony does have the same conff issue, but it happens afters he runs the command sucessfully. 22:47:13 Anyways, I'm sharing the fix you gave me before with him to see if there's any difference with his stuff 22:48:16 Just to make it a bit tidy for when you see this, this is the output of 'umlbox -B -v echo DEADBEEF' for me and moony 22:48:53 me: https://ghostbin.com/paste/as6r3 22:49:07 moony: https://ptpb.pw/Evrs 22:50:33 moony: Looks like you're getting the same "configuration repeats" thing we saw when debugging. 22:50:37 Well, as above. 22:50:56 well that'd explain why the bot takes forever to process 22:50:58 Yeah, it wouldn't really stop it from running the command, it'd just do some odd things afterwards. 22:51:16 I'm still not sure why it doesn't work for me 22:51:46 I've noticed that when moony runs something it seems like " | cat" is added to the command 22:51:52 my output doesn't do that 22:52:03 That's what it does when it thinks the output isn't a tty. 22:52:16 Yay. 22:52:18 which, in the case of my bot, it isnt. 22:52:49 wait. *makes connection* rdococ has been in ##werewolf all along and i never noticed. how. 22:52:59 ...:P 22:53:09 Nice. 22:53:50 I believe the | cat is added to make the command that gets run inside the UML kernel to similarly see a non-tty output. Because otherwise it sees the UML console, which always is a tty as seen from the inside, even if the output fd it's redirected to isn't. 23:02:08 If you want to try something out, maybe (temporarily) change the umlbox script's line "con1=" + childStdin + ",fd:" + str(childStdout), to instead be "con1=" + childStdin + ",fd:" + stdoutws, (and keep using the -v flag) 23:02:54 Okay 23:03:07 Wow. People figured out how to make dpkg work in linbut lol 23:07:11 fizzie, I get an error. 23:07:27 https://ghostbin.com/paste/cc4g5 23:07:37 $ input ../tty1 23:07:37 open(rfile, O_RDONLY): No such device or address 23:08:04 Sorry, that should've been: "con1=" + childStdin + "," + stdoutws, 23:08:19 Now you ended up with the argument 'con1=fd:0,fd:fd:1' which is one "fd:" too many. 23:09:38 https://ghostbin.com/paste/tkxnn 23:10:46 The error changed, fizzie. Now the device is busy. 23:11:16 Oh, that's probably because it's using stdoutws (aka fd:1) also for that other console spec. 23:11:59 You could definitely try to work around that as well, but I'm just puzzled as to why it's not working in the first place. 23:15:40 <\oren\> does anyone know how to use jenkins to talk to another jenkins 23:16:06 <\oren\> `? jenkins 23:16:50 jenkins? ¯\(°​_o)/¯ 23:18:01 -!- sleffy has quit (Quit: Leaving). 23:18:21 -!- sleffy has joined. 23:18:48 Well, it's a shame that there's no way to know what's wrong with it 23:19:14 I really want to get UMLBox working, but I guess that's enough trying for today 23:20:27 Well, hmm. 23:20:53 You could try to strace the kernel execution, but it might be doing a bit too much for that to be readable. 23:21:20 There's definitely something odd when it comes to the terminal handling. For me, umlbox works fine, but running it once somehow manages to break the stdin of subsequent commands, which I don't even understand how that's possible. I mean, look at this: http://sprunge.us/NKbS 23:21:36 yeah, a lot of weird stuff happens too 23:22:00 when I try to run sudo, I'm completely unable to input the password in the same terminal where I ran umlbox before 23:23:02 It's not really that great for interactive use, it might be best to stick with having some other program call umlbox for you, the way it works on HackEgo. 23:23:14 Who knows, it's even borderline possible it would work in that context. 23:23:18 fizzie, in order to check if the issue is if there's no output or if there's no visible, I should use umlbox to make a permanent change (ie touch a file or make a dir), which folder is writtable by umlbox? 23:24:31 Nothing on the host is writable by default. You can pass in an extra argument like -fw /some/dir which will mount /some/dir from the host to the guest in read-write mode. 23:25:54 it doesn't seem like it runs the command 23:25:58 so there's no output at all 23:26:24 I've tried with umlbox -B -v -fw /test touch /test/didit 23:26:30 there's nothing in /test 23:26:39 -!- wob_jonas has quit (Quit: http://www.kiwiirc.com/ - A hand crafted IRC client). 23:26:51 Does /test exist, and do you have write permissions in it as the user you run umlbox as? 23:27:04 (Also what do the logs look like?) 23:27:08 yes, and I ran umlbox as sudo 23:27:32 here's the output: https://ghostbin.com/paste/8xyvf 23:28:42 Hmm. I wonder if that might have something to do with permissions *inside* the UML. Try adding -s as well? 23:28:53 (It runs the command as root inside the UML.) 23:29:11 wait 23:29:13 so 23:29:19 instead of trying to run umlbox with sudo 23:29:32 I made myself owner of /test and tried again without sudo 23:29:35 this time it worked 23:31:22 I think that might be because the umlbox init doesn't really expect UML to be executed as root. 23:31:58 It uses uid/gid 0 to mean "unset" for the uid/gid it runs the command as, and when they're unset it picks random uid/gid. 23:32:21 kurolox, get in ##werewolf 23:32:24 (I guess in general there shouldn't be any reason to try running umlbox as root.) 23:32:30 fair enough 23:32:40 at least now I know that the stuff runs in umlbox even if I can't see it 23:32:42 -!- TieSoul has quit (Quit: Leaving). 23:32:52 http://i.imgur.com/dlA01qW.png 23:33:03 so we're back at the issues with console output 23:33:08 kurolox, ##werewolf 23:33:14 okay, okay 23:35:08 kurolox: Out of curiosity, what happens if you try something like this: http://sprunge.us/dTBG 23:35:21 -!- `^_^v has quit (Quit: This computer has gone to sleep). 23:38:15 fizzie: https://ghostbin.com/paste/dvb8c 23:38:25 Aw. 23:38:43 I guess you're still affected by whatever mysterious output redirection problems you're having. 23:38:49 So odd, though. 23:39:03 maybe redirecting the output to a file? 23:39:24 Well, I mean, that should *work*, but it's more than a little clumsy. 23:40:08 there are stuff that I'm not sure about though 23:41:57 Since you *are* seeing the init's output (and therefore clearly getting *something* out), if you really just want to hack it to make it work, chances are you could just fiddle with the conX= and subprocess.call arguments in the umlbox script until you hit a combination that works. 23:43:19 (And/or the "output ..." stanza it writes to the config file.) 23:43:34 I'm still not sure if it really works though 23:43:49 I think I'll try building a current kernel and see how that goes for me. 23:44:10 as in, when I try something with umlbox that shouldn't end inmediately (ie: the bot I'm trying to run) still ends inmediately 23:44:16 also 23:44:19 this might be interesting 23:44:24 there's output after the run 23:44:34 nothing relevant, but there's something 23:44:49 https://ghostbin.com/paste/2jhto 23:45:04 -!- AnotherTest has quit (Ping timeout: 255 seconds). 23:45:14 maybe that can help identifying the issue? 23:48:41 fizzie if it's useful for what you want to do, I'm running 4.12.8 in the host, and also 4.12.8 as the uml kernel 23:48:56 -!- ais523 has joined. 23:49:05 back 23:49:45 Sounds like "uninitialized urandom read" is a kernel message, which probably explains why you're seeing it. 23:49:57 It'd go to the same console all those debugging lines do. 23:50:49 oh, okay 23:51:10 actually fizzie, if you feel like replicating the issues I'm having, doing a fresh arch linux install should do the trick 23:51:41 it's what I've done in my laptop, I installed it fresh yesterday and it's having the exact same issues I'm having with my desktop, so chances are you will have them too 23:51:45 If you want a hacky trick to try, locate the lines in the umlbox script that do the input ../tty1 and output ../tty1 and change them to input /console and output /console instead. (/console is a file the umlbox init makes and uses for its own output.) 23:51:58 okay 23:52:04 ais523: Here's a funny thing: http://sprunge.us/NKbS 23:53:08 fizzie: is that second cat running inside or outside umlbox? 23:53:16 ais523: Outside. 23:53:35 ais523: It leaves the terminal in that state, and I don't know of a way to undo it. 23:53:54 OK, so that error message is EAGAIN 23:53:59 fizzie, no such file or directory 23:54:19 https://ghostbin.com/paste/kvpg5 23:54:45 can you find out which system call is erroring out? "strace cat" would normally be enough, you might need to redirect the output to a file though (strace has an -o option to write to a file) 23:55:00 kurolox: Oh, sorry, make that "../console" instead. Looks like init prepends "/host/" to it. 23:55:06 my guess is that one of the standard file descriptors has somehow been set to non-blocking mode, that'd be an easy way to cause spurious EAGAINs 23:55:27 ais523: Ooh, nonblocking, that sounds plausible. 23:55:49 HEY 23:55:52 I GET OUTPUT NOW 23:56:12 now I see why the bot wasn't working, I wasn't mounting /mnt so it couldn't read the bot file 23:56:36 I love you fizzie, I can't thank you for all the help you've been offering me the last days 23:57:32 You can't? 23:57:39 there's something a bit weird though, fizzie 23:58:04 it seems like I can see the output by running stuff with -v, but nothing without it 23:58:15 ais523: Yeah -- read(0, 0x7f086c62c000, 131072) = -1 EAGAIN (Resource temporarily unavailable) -- and: http://sprunge.us/FCWe 23:58:41 https://ghostbin.com/paste/6pffa 23:58:59 this sounds like a mistake in the shell somehow? it shouldn't be letting applications it runs permanently change the mode of its file descriptors
