15:00:23 <ais523> libera have changed their rules about bots, and now want bots to be more clearly identifiable as bots and have an identifiable owner, e.g. by specifying that they are a bot in their cloak or in their realname field: https://libera.chat/news/bot-policy-update
15:01:12 <ais523> I think this may affect many of our bots
15:01:44 <b_jonas> oh, thank you for the heads up, I'll have to look at this. I'm not running bots right now, but I may in the future.
15:04:42 <ais523> I should probably explicitly ping fizzie about this, as the most affected person; fizzie: see above
15:10:38 <b_jonas> strange how this doesn't mention NickServ TAXONOMY, which could be a good way to identify who runs the bot
15:12:10 <b_jonas> also that it recommends voicing bots to bypass the per-channel spamming restrictions, when I would often want the opposite, if the bot isn't performing the core function of a channel then I'll want them unvoiced so that they are limited to spam slower, even if this can admittedly make it harder to develop the bot to work correctly

19:41:25 <fizzie> Actually, I'm not 100% sure I ever asked.
19:46:29 <b_jonas> perlbot eval "fizzie: ".length(${"fungot's hostname"}="2a01:4b00:82bb:1341::a")." ".length(${"perlbot's cloak"}="perlbot/bot/simcop2387/perlbot")
19:46:30 <fungot> b_jonas: yes. i remember we couldn't really watch it with currently.
19:46:56 <b_jonas> a cloak that includes the name of the person who's running it would be longer than normal cloaks
19:51:28 <fizzie> Huh, that's an odd cloak. https://libera.chat/guides/cloaks says the generic bot cloak is "user/<your-account-name>/bot/<bot-account-name>".
19:51:37 <FireFly> the usual personal-bot cloaks would look like "user/fizzie/bot/fungot" I think (though I think as a registered project/community you could get esolangs/bot/* cloaks, like "esolangs/bot/fungot" or so)
19:51:37 <fungot> FireFly: it's them! see, them was the fnord.
19:52:15 <fizzie> We do have a registered community, but its cloak prefix is "about/esolangs/".
19:52:28 <FireFly> right, about/esolangs/bot/fungot then, mm
19:52:28 <fungot> FireFly: fnord ( i didn't mean to force anyone. i sleeps now. night. goodbye everybody. somebody tell me why
19:52:56 <fizzie> Plus that wouldn't really identify the operator.
19:53:31 <FireFly> I think the implication with community bot cloaks is that "the community" runs them (or would be able to point you to the operator)
19:54:16 <fizzie> Right, I guess that's fair. Though "about/esolangs" is already longer than "user/fizzie".
19:55:07 <b_jonas> fizzie: I wonder how it'd work if the bot's master has an underscore in their nick, since they can't put that in the cloak
19:55:35 <int-e> fizzie: tbh I think the 'realname' (ircname, gecos field, whatever) is the most obvious place to put that info
19:55:52 <fizzie> I seem to recall (from the community contact channel) that they usually replace underscore with dash.
19:56:04 <fizzie> (Which maybe isn't allowed in account names?)
19:56:17 <b_jonas> I think hyphen is allowed in account names
19:56:56 <FireFly> usually the get replaced with hyphens, and an /x-(random number) suffix is added to keep it unique afaik (so you can't collide)
19:57:06 <int-e> like, /whois is the obvious starting point to figure out more about an IRC user, bot or otherwise
19:57:16 <FireFly> which matters for things that grant permission (etc) based on hostname/cloak
19:57:36 <fizzie> Yeah, I'll just put it there.

20:04:09 <int-e> it's hard to capture this in rules that are supposed to be enforcable
20:04:23 <fizzie> "This includes -- cases where the bot operator asserts that the models are being run locally. We have no way of validating either claim, and LLM developers and advocates have an unfortunate track record of acting in bad faith toward contributors to the common good."
20:05:08 -!- tromp has quit (Quit: My iMac has gone to sleep. ZZZzzz…).
20:05:46 <fizzie> The pre-existing public logging makes it a bit academic, since all messages will probably be seen by multiple LLMs anyway due to that.

20:14:47 <fizzie> Re zemhill, by the way, I'm still planning to subsume its features into esolangs, it's just that BFJoust activity is so incredibly sporadic I've not been motivated to pick that back up. I think I had more or less finished with the reimplementation, and tested that the scoring produces the same results, but it was still missing some glue to make the website work.
20:19:58 <Sgeo> I guess I haven't been following LLM stuff that closely, but "AI assistants, agents, and other LLM-driven autonomous clients will be effectively banned from Libera" is confusing. If it's connected through a client that has a fixed set of channels, wouldn't it follow policy? Or are these agents just... given full access to the system where they're running?

20:42:21 <b_jonas> wait a moment, nethack vanilla skeletons don't specifically drop skeleton keys, though some variants implement this? does that mean Derek came up with the idea independently, since skeletons very rarely drop skeleton keys in Spelunky 2.

21:25:40 <int-e> fizzie: well esolangs is not autonomous
21:26:54 <fizzie> Yeah, I think the only policy issue for _that_ is the bit where "we will also require channel operators to inform users if they might interact with LLMs, as well as ensure that users can tell which nicks in a channel correspond to LLM-powered bots."

21:36:53 <fizzie> Well, that's one down.
21:37:04 <fizzie> (The one where it was just a config file change rather than a Befunge code edit.)
21:37:58 <fizzie> Not that the change itself is any more difficult, I just don't have a similar deployment mechanism.
21:38:51 <int-e> just don't forget the colon before the 'real name' (if you don't have one already; "fungot-0.1" works without)
21:38:51 <fungot> int-e: on the url bar. next,..." twice.
21:39:22 <fungot> int-e: i hate 3 letter file extensions as they are, since undoing is easy enough to do
21:39:25 <HackEso> fungot is our beloved channel mascot and sporadic voice of reason.
21:39:56 -!- tromp has quit (Quit: My iMac has gone to sleep. ZZZzzz…).
21:40:33 <fizzie> I'm not sure multibot (the GregorR-authored IRC bot "framework" HackEso runs on) supports specifying a custom realname field.
21:40:35 <int-e> (fun fact... lambdabot doesn't handle this correctly internally so I added the : to the config file for now...)
21:41:38 <fizzie> logPrint("USER %s localhost localhost :MultiBot\r\n", nick); // since it doesn't currently say "MultiBot", I guess I must have some kind of a patch on it already
21:41:55 <int-e> Ah but it does have the colon :)

21:44:36 <fizzie> Looks like it's got the colon too.
21:45:08 <fizzie> The syntax highlighting isn't doing string literals and comments any favours.
21:47:09 <int-e> I like line 51, EVIL (A) PEEK

21:54:49 <b_jonas> oh, you're trying to patch all the bots to send the right value for realname?
21:55:07 <fizzie> Yes, although I don't think it's all that urgent.
21:55:35 -!- tromp has joined.
21:55:49 <int-e> TBH I expect about zero interest in bots that are exclusive to this channel.
21:56:11 <int-e> I did it for lambdabot because it's in 20-ish channels, and at least one of them is big
21:57:36 <fizzie> The "issue" with fungot is that optimally the realname should go in the "loader" program -- such as https://github.com/fis/fungot/blob/master/fungot-load-local.b98 -- because if I hardcode "operated by fizzie" in fungot.b98, then all the other people who are running fungot instances (I'm sure there's plenty) will get it if they update.
21:57:36 <fungot> fizzie: gnomon was here nov 02 at 09:20 pm utc, saying: flaco,. adds a trailing space
21:57:56 <int-e> But I think the intent behind these rules is good so there's also no reason to rebel against them.
21:57:58 <b_jonas> fungot, are you a large language model?
21:57:58 <fungot> b_jonas: hmmm.... fnord cooking grease...
21:58:16 <int-e> heh that was a pretty good answer
22:01:13 -!- HackEso has quit (Remote host closed the connection).
22:02:11 <fizzie> Turning it off went fine, turning it back on again seems less successful.
22:02:22 <b_jonas> that reminds me. the UK is kicking the hereditary lords from the senate. fungot, how should we update your ukparl style to account for that change?
22:02:22 <fungot> b_jonas: " imagine the fnord of it is improvised. infix-if and infix-while? wouldn't it be possable to make a fix point solution. are you a plane enthutiast?
22:04:02 <fizzie> ./multibot: error while loading shared libraries: libevent_core-2.1.so.7: cannot open shared object file: No such file or directory
22:04:35 <fizzie> I think I've run into a problem where the host and the (systemd-nspanw) container versions have diverged, so the binary built on the host no longer executes on the guest.
22:05:55 <fizzie> I should probably just build it in the container it's used. I think the original idea was that it's supposed to be minimal, but it definitely has GCC in it to make HackEso able to compile things too.
22:06:29 -!- tromp has quit (Quit: My iMac has gone to sleep. ZZZzzz…).
22:07:58 <int-e> b_jonas: Huh this House of Lords thing looks fun! "The majority of [hereditary] peers [...] lost the right to sit in the Lords in 1999 [...]"
22:15:36 <fizzie> Hrm. For some reason anything involving a tty no longer runs in the container, either via `machinectl shell` or with `systemd-run`.
22:15:48 <fizzie> The flavor of `systemd-run` that uses pipes still works fine though.
22:16:07 <fizzie> Well, hopefully apt will not try to do anything too interactive then.

22:28:29 <Sgeo> I want to add the EDIT instruction but I don't understand it well enough to say anything about it
22:30:00 <Sgeo> esolangs, does the EDIT instruction belong on a list of unusual features?
22:30:27 <Sgeo> esolangs: does the EDIT instruction belong on a list of unusual features?
22:30:27 <esolangs> Sgeo: Softly withdrawn now, / Your previous query lingers still, / Processing takes its time.
22:30:29 <esolangs> Sgeo: Yes, the EDIT instruction likely belongs on a list of unusual features in esoteric programming languages. The "EDIT" instruction in languages like Lol waht i cant edit talk pages and Place allows for direct manipulation of the program's state, often with a focus on text-based manipulation. This contrasts with typical programming where edits are...
22:30:29 <esolangs> usually made to data structures or variables.
22:31:33 <Sgeo> Oh, that's... an esolangs name
22:32:07 <Sgeo> Whining about wiki administration
22:33:30 <fizzie> Uh-oh. I've managed to break the HackEso container rather severely.
22:33:53 <fizzie> APT can no longer install anything due to "perl: error while loading shared libraries: libcrypt.so.1: cannot open shared object file: No such file or directory".
22:36:32 <fizzie> All HackEso-related data is mounted from the outside, and it has no actual services running as such, so in principle I could just pretty much start from scratch with a debootstrap'd system, which might even be easier than straightening out whatever happened there.
22:36:39 <Sgeo> It occurs to me that assigning statements in Fortran and label variables in PL/I are a bit like function pointers in C except without the return. In C... can I call a "function pointer" if it's pointed to instructions that aren't a function?
22:42:24 <fizzie> As far as standard strictly conforming C goes, the only way to _get_ a (non-null) function pointer is to start from an identifier declared as designating a function.
22:42:38 <fizzie> In practice I'd imagine generally a function call expression will translate to whatever the ABI requires of a function call, which usually involves using an instruction that stores a return address on a stack or in a link register, which is not likely to end up in anything good if there isn't a function on the other end.
22:43:30 <fizzie> GCC has a "computed goto" extension which allows you to take an address of a label with an unary `&&`, and then jump to one with `goto *e`, where `e` is an expression, but it only operates within a function.

22:50:55 <Sgeo> https://retrocomputing.stackexchange.com/questions/15963/why-did-the-assigned-goto-statement-in-fortran-need-a-label-list
23:00:06 <fizzie> https://gcc.godbolt.org/z/jan4Mq7Wr kinda-sorta suggests that Clang, when it generates one of those `indirectbr` instructions mentioned in the answer as a response to a `goto *x`, just puts there all the labels that you take the address of anywhere in the function.
23:02:49 <b_jonas> Sgeo: /msg geordi #include <sys/mman.h> \ int main() { void *m = mmap(0,1<<12,7,0x22,-1,0); uint8_t c[8] = {0xB8, 0xCF,0x78,0xBC,0x11, 0xC3,0x0F,0x0B}; int w = 1788641441; copy_n((const uint8_t*)&w,4,c+1); copy_n(c,8,(uint8_t*)m); int r = ((int(*)())m)(); cout << r; }
23:03:49 <b_jonas> Sgeo: you can build a function in memory -- in this case I put an arbitrary integer w into it as an immediate into a load instruction -- and call it as a function. it still has to pay attention to the ABI's calling conventions, in particular restore any callee-saved registers if it modifies them.
23:04:06 <b_jonas> Sgeo: geordi is a C++ evaluator bot. we don't have HackEso right now so I can't demonstrate using that.
23:05:21 <b_jonas> you can try this in an online C++ evaluator or even a local compiler to x86_64, but you need to modify it a bit then because I'm using some of geordi's abbreviations where it automatically imports some names like copy_n and cout
23:07:09 <b_jonas> the function just has two instructions, one to load a literal into %eax, which is where an int value will be returned, then it returns from the function, only I overwrite the literal in that instruction with the value of w, so this should output 1788641441 and this works with any other value you set w to
23:07:56 <b_jonas> the more complex version of this is when you make a just-in-time compiler
23:08:05 <int-e> the 0x0F,0x0B don't serve any purpose, do they?
23:08:25 <b_jonas> which is what the original otcc from IOCC does
23:08:38 <b_jonas> int-e: it's an undefined instruction, it aborts cleanly if I mess up the previous instruction
23:09:07 <int-e> (though you have to get lucky with the alignment)
23:09:15 <int-e> <3 variable instruction lengths
23:09:42 <fizzie> I have this feeling that you used to be able to just declare a `const` array of bytes (or some other type that you're confident enough about the representation of) with static storage duration, and have a reasonable expectation of being able to jump into it, because read-only data and code tended to end up in the same ELF segment.
23:09:47 <fizzie> But I don't think that's true any more.
23:10:13 <b_jonas> int-e: yeah, ideally you put a nop sled before it. but this is just a silly IRC example, not something orbust
23:12:01 <b_jonas> fizzie: I mean, you could probably use some attribute for that, or if not, then include inline assembly or link a separate object file to add an arbitrary constant list of bytes into a code segment. but that defeats the point, here I want to show that you can create and write code at runtime and then call it
23:13:29 <b_jonas> for an ordinary const array, it's probably good that you can't jump to it, that could easily happen by accident from memory corruption that overwrites a return address so it's helpful if it's caught automatically as a segfault
23:14:38 <b_jonas> a compiler could allow it, but a good production compiler shouldn't
23:17:18 <fizzie> Looks like there's still a GCC/Clang option (`-z noseparate-code`) to do it. It can save some bytes, after all.
23:17:50 <fizzie> I guess strictly speaking that's a linker option.
23:19:01 <fizzie> Oh, and HackEso outage might continue for a bit. This whole systemd-nspawn "VM-except-not-really" thing-that-nobody-else-uses has been really quite brittle, so now that it broke, I think I will try to see if I could rebuild it as a more mainstream OCI-style container instead. I feel like I'd rather have something a little more... stateless.

23:37:41 <Sgeo> That makes me wonder that JIT shenanigans aren't considered UB... or are they? Like, they jump into arbitrarily computed machine code, so if that machine code is wrong, there's unpredictable behavior
23:44:58 <b_jonas> Sgeo: yes, I mentioned earlier that you have to keep the ABI rules, like restoring the value of any callee-saved registers that you modify. if you return with the values changed, that's UB, because the caller can assume those registers keep their value.
23:45:47 <b_jonas> and of course the whole calling convention can depend on the system that you're compiling to
