00:21:29 <Zarutian> boily: hmm... how much do you know of ISAs?
00:23:05 <Zarutian> boily: well on canonical dual stack machines they are simple. Basically they are unanticipated call to the InteruptServiceRoutine.
00:23:26 * boily throws a smoke grenade
00:25:21 <Zarutian> I take that you know the basic Fetch-Execute cycle all CPUs and MCU cpu-like cores implement
00:27:51 <boily> `` mv wisdom/magnu{,s}
00:28:37 <Zarutian> so the cpu usually fetches an instruction from what ever address the Instruction Pointer register tells.
00:30:32 <Zarutian> however when an interupt happens, some sort of signal (a steady logical HIgh or LoToHi transition) is fed into the contoler of the cpu, yes?
00:33:15 <HackEgo> 2016-10-20 <boil̈y> ` mv wisdom/magnu{,s} \ 2016-09-25 <fizzïe> revert 942e964c81c1 \ 2016-09-25 <evilips̈e> ` chmod 777 / -R \ 2016-04-17 <b_jonäs> learn Magnus is the ghost the Trunchbull killed.

00:34:51 -!- Cale has quit (Remote host closed the connection).
00:35:09 <Zarutian> oerjan: men du forstuer hvad jeg har sagt på lojban, nei?
00:35:53 <boily> Zarutian: *munch* *munch* *munch*
00:36:25 <boily> (eating, still following what's happening, even if parts are in Norsk or something that looks like it.)
00:37:27 <Zarutian> boily: well the last was in an baster coboil of Norks and Dansk.
00:42:34 <oerjan> "forstuer" is probably the wrong term here hth
00:43:13 <Zarutian> so, the cpu pushes the current Instruction Pointer register contents onto the (return)stack, puts the address of the start of the ISR into Instruction Pointer register, disables interrupts and fetches the next instruction as per above.
00:43:21 <oerjan> (it means "sprain" hth)
00:43:43 <Zarutian> oerjan: could have gone with Svensk fattar instead probably
00:44:11 <oerjan> i'm pretty sure you meant "forstår"
00:45:08 <Zarutian> hence I sometimes get deep oiled kittens instead of chickens.
00:45:24 <oerjan> google translate's lojban support is unfortunately rather nonexistent, so no deal.
00:45:46 <Zarutian> well when I am trying to speak Dansk that is
00:46:21 <Zarutian> oerjan: humm... hvernig höndlar þýðingarvél Google íslenskt ritmál þá?
00:46:56 <boily> . o O ( mais qu'est-ce qu'un þýðingarvél??? )
00:47:23 <oerjan> incidentally "fatter" is a norwegian word, which means the same as swedish "fattar", except when it means Daddy instead.
00:47:48 <oerjan> (it's not the most common word for Daddy, though.)
00:49:10 <Zarutian> there are few design choices of where the ISR address is gotten from. In some systems it is hardcoded. In others it is in an memory addressable register and in yet other you get vectored interrupts where the ISR address is choicen from an small array of register based on the type of the interrupt
00:49:14 <oerjan> Zarutian: better than lojban. also i can guess a little icelandic.
00:49:57 <HackEgo> Thanks, Zarutian. Tharutian.
00:51:08 <Zarutian> boily: another example of an long Icelandic word is alþjóðafarverkamannastarfsgreinasambandið (and I bet oerjan cant guess this one)
00:51:37 <oerjan> boily: þýðingarvél seems to mean translator. þýðing has an obvious norwegian nynorsk cognate tyding (and a slightly less obvious bokmål betydning), both meaning meaning. not sure of the vél part.
00:51:55 <boily> mine eyes. they are not in a happy place.
00:52:15 * boily comforts himself with sane French spelling
00:52:16 <oerjan> it seems to mean machine according to google.
00:52:43 <oerjan> boily: i think icelandic spelling is relatively sane.
00:52:52 <Zarutian> oerjan: indeed, it was adopted to mean that but also meant certain kind of magic|spell
00:53:34 <oerjan> i cannot guess all of that long word but sambandet is a norwegian word.
00:54:18 <oerjan> it might be a funny way of saying Internet, come to think of it.
00:54:57 <boily> `` sed -i 'streatréat' wisdom/montreal
00:55:24 <oerjan> looking at the mess google creates of it...
00:55:40 <oerjan> i'm changing my guess to ILO, the International Labor Organization.
00:55:41 <Zarutian> oerjan: nope the Internet is Alnetið, rather sane one that.
00:56:37 * Zarutian breaks it up for oerjan: alþjóða-far-verkamanna-starfsgreina-sambandið
00:57:58 <oerjan> i was getting that far
00:58:45 <oerjan> still the same guess, unless there's a different international worker's union
00:59:29 <oerjan> https://en.wikipedia.org/wiki/International_Workers%27_Association looks promising
01:00:38 <Zarutian> oerjan: well its an international umbrella organization for guild-like organizations of travelling workers.
01:00:54 <boily> "just" is #esoteric's version of TV Tropes' "egregious"...
01:01:37 <oerjan> Zarutian: doesn't sound quite the same. i guess there are too many labor organizations
01:01:56 <oerjan> boily: i haven't noticed "egregious"
01:02:22 <Zarutian> boily: well an roadtrip faviourite is always: Hellisheiðarvegavinnuverkamannkaffiskúrslykklakippunaglhaus
01:02:48 <boily> oerjan: it was egregiouser in the past, but they removed many of them.
01:02:58 <boily> (it's still the canonical egregious word.)
01:03:22 * boily mapoles spaces into the Zarutianwords
01:03:45 <boily> I'm guessing "Hell" is not Hell, but just pale or white.
01:03:56 -!- Cale has joined.
01:04:29 <Zarutian> in Icelandic we have four declanations instead of the measly two of English
01:05:18 <Zarutian> Hellisheiði is a named georgraphy in Iceland
01:05:45 <oerjan> Zarutian: do you mean cases
01:05:56 <oerjan> declinations count a different thing
01:06:33 <Zarutian> my english vocabulary regarding grammar isnt much
01:07:17 <oerjan> well english probably doesn't have declinations since its noun grammar is too regular. not sure about icelandic.
01:07:41 <oerjan> (basically a declination is a class of nouns that all inflect in a similar way)
01:08:06 <Zarutian> declanations is where nouns get diffrent endings depending on stuff like the 'sex' of the word and such?
01:08:28 <oerjan> well those might count, however it's not the same.
01:08:54 <oerjan> e.g. in Latin some of the declinations contain words of different genders.
01:09:08 <Zarutian> that is what I am talking about
01:09:53 <oerjan> no i mean, Julius and verbum are latin words both of the 2nd declination; the first is masculine and the second is neuter.
01:10:40 <oerjan> and the most common adjective inflection uses 1st declination for feminine and 2nd for masculine and neuter.
01:10:44 <Zarutian> barn-ið, bók-in, hestur-inn. (Neuter, feminine, masculine, the ending is equiv to danish -en or english the)
01:11:04 <oerjan> Zarutian: danish as -et for neuter
01:11:51 <oerjan> declination also refers to the entire inflection pattern of a noun though.
01:12:01 <Zarutian> dont force me to remember the rules of what words are neuter and combined (both mascuiline and feminine)
01:12:28 <oerjan> well norwegian has 3 genders. barnet, boka, hesten. same as icelandic there.
01:13:24 <boily> un évier, une cuiller. perfectly logical.
01:14:18 <boily> (mind you, it's /evje/ and /kɥijɛʁ/.)
01:14:42 <pikhq> English has the *remnants* of a noun declination system, at least. I think purely in the pronouns, though.

07:15:41 <hppavilion[1]> ? `le/rn Sid Meier/Sid Meier was invented by Taneb_Omega, who was invented by Taneb_(Omega-1), who was invented by Taneb_(Omega-2) who was invented by ... who was invented by Taneb_2, who was invented by Taneb_1, who was invented by Taneb_0, aka Taneb.
07:16:13 <HackEgo> It is rumoured that Taneb invented civilization, but this is false. It was actually invented by Sid Meier, who also invented cities.
07:16:43 <lifthrasiir> hppavilion[1]: so Taneb transitively invented civilization?
07:16:46 <alercah> Sid Meier is not a recursive Taneb-vention!
07:17:04 <hppavilion[1]> lifthrasiir: We've established that invention is not transitive. Apparently.
07:17:22 <hppavilion[1]> alercah: Of course not; he's an invention from the bottom of an infinite tower of Tanebs
07:19:42 <hppavilion[1]> imode: 33 is also a natural log of 2; 2**ln(155.15026817143126[digits omitted]). hth.
07:23:08 <lifthrasiir> hppavilion[1]: I've chosen to differentiate myself from that style
07:23:45 <hppavilion[1]> ('integral' as in integer-related, not as in squiggly)
07:24:02 <lifthrasiir> ah, I thought it is related to the relationship between infinite integral and logarithm
07:25:12 -!- AnotherTest has joined.
07:25:46 <hppavilion[1]> lifthrasiir: And really, how natural is one's life? It cannot be broken down into a mere boolean.
07:26:01 <imode> none of this is making any rational sense.
07:26:48 * lifthrasiir has thought of punning with p-adic numbers
07:26:55 * imode wonders what a base-agnostic "bit shift" would look like.. perhaps a digit shift?
07:27:02 <hppavilion[1]> lifthrasiir: Only by rejecting the orders of our cardinals can we fulfill are dual nature and achieve transcendence
07:27:08 <imode> so 123 << 2 would end up as 300...
07:27:17 <shachaf> that's not how ordinals work and it's overdoing it anyway

07:31:59 -!- AnotherTest has quit (Ping timeout: 256 seconds).
07:32:10 <izalove> i wrote a function that frees some resource
07:32:24 <izalove> s* s_free(s*); <- prototype looks like this
07:33:00 <izalove> i also have a function that copies stuff from one resource to another and allocates space for it if needed
07:33:10 <hppavilion[1]> lifthrasiir: With the amount of pun I bestowed on you, we can never be even.
07:33:11 <izalove> s* s_dup(s* dest, const s* src);
07:33:39 <izalove> which means you can do something like this s_dup(s_free(h->values[pos]), value);
07:34:25 <izalove> it frees up the space used by its argument
07:34:42 <shachaf> But then its argument is still valid?
07:35:03 <izalove> that argument is more like a char**
07:35:55 <izalove> s is a union that contains a pointer to heap allocated memory
07:36:53 <shachaf> OK, so that's similar to free(*h->values[pos]); *h->values[pos] = alloc(); copy(*h->values[pos], value);?
07:37:41 <izalove> but i'm doing it like dup(free(oldvalue), newvalue)
07:39:05 <izalove> basically all my functions return their first argument to allow that kind of chaining
07:39:16 <shachaf> I should have said copy(*h->values[pos], *value);
07:39:52 * izalove didn't notice the missing *
07:40:16 <shachaf> This seems like a slightly odd thing to do.
07:42:11 <izalove> because free is supposed to be void?
07:42:33 <izalove> one can also use function(something)->field = value
07:45:34 <shachaf> Well, free puts its argument in an odd semi-valid state.
07:46:08 <izalove> oh no it's completely valid
07:46:44 <izalove> https://github.com/izabera/s
07:47:54 <shachaf> Oh, you're just inconsistent within the file.
07:48:13 <shachaf> I thought it was some odd scheme where things outside the function arguments are spaced differently from function arguments.
07:48:38 <hppavilion[1]> I just found out what a polecat (hov http://xkcd.com/1032/) is
07:48:59 <izalove> shachaf: actually that's it
07:49:33 <shachaf> But then you write "s* s_cat(s* a"
07:50:04 <izalove> i haven't really decided where the * should go
07:50:35 <shachaf> the right answer is "t *x" hth
07:50:48 <shachaf> (But as long as you're consistent I don't really care.)
07:51:28 <shachaf> Anyway, I'm still not sure whether this is a good API.
07:52:47 <shachaf> Why do you restrict capacity to powers of 2?
07:53:32 <izalove> and because i'm a computer person so powers of 2 are the way to go
07:53:38 <shachaf> Do you think the same use cases require 2^54-byte strings and also compact 15-byte strings?
07:53:42 <imode> the latter reason is valid.
07:54:09 <shachaf> anyway have you read e.g. https://github.com/facebook/folly/blob/master/folly/docs/FBVector.md
07:54:43 <shachaf> "it can be mathematically proven that a growth factor of 2 is rigorously the worst possible because it never allows the vector to reuse any of its previously-allocated memory"
07:55:18 * shachaf shudders at "if (...) ... else { ... }"
07:55:25 <shachaf> I shouldn't complain about your formatting.
07:55:29 <lifthrasiir> izalove: oh, I've read it up and it's a bit clever
07:55:39 <shachaf> But you should really just run it through clang-format or something.
07:55:54 <lifthrasiir> I'm aware of SSO-23 and thought how can it be possible to have 16-byte-long structure without a capacity
07:56:48 <izalove> shachaf: thanks for the link
07:57:04 <shachaf> Anyway none of this is answering your question.
07:57:13 <izalove> lifthrasiir: sso23 is 24 bytes
07:58:38 <izalove> yeah, functions that return their first argument for chaining purposes
07:59:37 <shachaf> I think for free in particular it's pretty odd.
08:00:08 <hppavilion[1]> lifthrasiir: Are you just never going to acknowledge my pun?
08:00:47 <HackEgo> Puns are fun. Ask shachaf about them. But beware of Muphry adding misspellings.
08:01:12 <lifthrasiir> hppavilion[1]: sorry, was confused on what parts are intended to be pun
08:02:11 <hppavilion[1]> lifthrasiir: went to far with the pun or it's out of scrollback?
08:02:13 <imode> don't worry, I'm sure it was punintentional.
08:02:40 -!- augur has quit (Remote host closed the connection).
08:02:55 <lifthrasiir> izalove: I wonder if that style of API will survive future expansion of convenience APIs, like sprintf
08:03:48 <izalove> sprintf typically returns an int but s knows its size so it could just return its first arg
08:03:56 <hppavilion[1]> lifthrasiir: It was "Only by rejecting the orders of our cardinals can we fulfill are dual nature and achieve transcendence"
08:04:21 <lifthrasiir> hppavilion[1]: yeah I think that pun is being uncountable
08:05:07 <izalove> yeah sds has something like that

08:07:49 <lifthrasiir> izalove: I personally hope to see an equivalent to std::string_view in C
08:08:47 <izalove> who needs a size when you've got a null terminator
08:08:52 <shachaf> Even in C++11 one is tempted to use char * instead of string_view
08:08:58 <shachaf> And do all sorts of arithmetic.
08:09:13 <shachaf> Fortunately you just have to be smart and never get it wrong, so it works fine.
08:10:53 <lifthrasiir> izalove: so we've got a stupidity like strtok, haven't we?
08:11:25 <izalove> i have yet to write it for s
08:13:13 <lifthrasiir> izalove: on the capacity: I think it is clever, but doubling every time is not optimal for larger strings
08:13:34 <lifthrasiir> I've once had 64KB cut in my C string library; sds seems to have 1MB cut
08:13:57 <lifthrasiir> beyond that point the amount of additional allocation is limited
08:14:39 <lifthrasiir> e.g. with 1MB cut, appending two bytes to a string with len=32767 cap=32768 will yield one with len=32769 cap=65536
08:15:07 <lifthrasiir> but doing the same to a string with len=2^24-1 cap=2^24 will yield one with len=2^24+1 cap=2^24+2^20
08:15:50 <lifthrasiir> allocation request basically strains the allocator, so excess allocation should be limited to some threshold
08:17:01 <lifthrasiir> shameless plug: https://gist.github.com/lifthrasiir/4422136
08:17:18 <lifthrasiir> not exactly a string, though (I forgot that :p)
08:18:27 <izalove> my gut feeling is that large strings are more likely to be appended large amounts of data
08:18:56 <izalove> so once you're past 100mb it makes little sense to grow by 1mb at a time
08:19:23 <lifthrasiir> izalove: any incremental building can result in such a behavior
08:19:38 -!- imode has quit (Ping timeout: 250 seconds).
08:19:59 <izalove> yeah but what if you resize by decreasing increments
08:20:09 <izalove> like, a 16byte string gets resized by 2x
08:20:16 <izalove> 32 byte gets resized by 1.9x
08:20:27 <izalove> ... 100 mb gets resized by 1.5x
08:20:51 <izalove> something that decreases logarithmically
08:22:25 <lifthrasiir> yeah, but copying 32 byte string is quick; copying 100 MB string is not
08:23:30 <izalove> that doesn't seem to be a point against what i said
08:25:01 <lifthrasiir> that might somehow work, but I guess 1.5x is still a bit large

14:25:03 <b_jonas> ais523: at least in the age of the Cities. later in the Empire the robots build a few more, and a few of them are significant characters.
14:25:37 <ais523> b_jonas: IIRC that's intentionally ambiguous in the books
14:26:18 <b_jonas> ais523: that depends on which characters you're talking about
14:28:38 <b_jonas> ais523: SPOILER Stephen Byerley is definitely ambiguous, nobody will be able to tell whether he was a robot; Dors Venabili was definitely a robot, it's slightly ambiguous in Prelude to Foundation but clear in Forward the Foundation;
14:29:13 <ais523> oh, I thought even Forward was intentionally ambiguous, but less so
14:29:32 <ais523> Byerley is clearly ambiguous (although I'm also unclear if that story is in the same continuity as the others)
14:30:26 <b_jonas> in any case, even if Forward is ambiguous, there's the Foundation's Triumph trilogy which makes it clear that Dors is a robot and IIRC also introduces at least one more humanoid robots.
14:31:13 <b_jonas> In addition, according to Foundation and Earth, Daneel has had more than one humanoid body, so I wonder if he should be counted with multiplicity.
14:32:17 <ais523> technically speaking we only have his word for that, but there's not much reason to think he was lying
14:32:55 <b_jonas> ais523: Byerley is definitely in the same continuity as the robot novels, at least as far as there's such a continuity: Byerley (from "Evidence") re-appears in "The Evitable Conflict",
14:33:23 <ais523> b_jonas: I was more questioning if that was in the same continuity as, say, The Caves of Steel
14:33:39 <ais523> I'm not sure if the Evidence continuity even features Susan Calvin (it might; I can't remember)
14:33:50 -!- Cale has joined.
14:35:39 <fizzie> The Evidence story has Susan Calvin in it.
14:36:05 <b_jonas> I think they're sort of both the same continuity, the one where the spacers first wage war against Earth, as told in, uh which story is that about the war when Earth is defeated, anyway, that happens much after The Evitable Conflict and I think before Caves of Steel?
14:36:14 <b_jonas> I'm not sure of the chronology here, I'd have to look it up
14:37:14 <fizzie> She provides the last bit about Byerley becoming the World Coordinator, foreshadowing The Evitable Conflict.
14:37:18 <fizzie> Also he's totes a robot.
14:37:55 <b_jonas> In fact, it's The Bicentennial Man, which btw has another humanoid robot, which doesn't really seem to be integrated to the continuity with the spacers.
14:39:03 <b_jonas> It's actually connected story-wise, because for a while Andrew works on the moon base where they're researching faster-than-light travel, and the story of that research is told in two or three of the other robot stories. It just doesn't feel like the same world to me for some reason.
14:40:02 <b_jonas> And the short story version of The Bicentennial Man is anthologized in The Complete Robot, so it's definitely one of those robot stories.
14:40:03 <fizzie> It doesn't feel like the same world because all the other books are so strict about US Robotics robots never being allowed to move around freely on Earth, but Andrew does that and nobody as much as raises an eyebrow.
14:40:22 <fizzie> Well, maybe not "all the other books".
14:40:23 <ais523> I'm pretty sure The Bicentennial Man is a different continuity from The Caves of Steel
14:40:33 <fizzie> But that's a plot point in many of the books.
14:40:38 <b_jonas> fizzie: I think that's chronology difference. The Bicentennial Man happens later.
14:40:41 <ais523> even if it's a very similar universe
14:41:05 <ais523> fwiw, although some of the original robot stories (I, Robot and the like) are clearly in the same continuity
14:41:11 <ais523> I think that many of them are negative-continuity one-offs
14:41:15 <b_jonas> ok wait, which one is the story about the war when the spacers attack Earth and blockade it?
14:41:21 <ais523> (i.e. "the story is set in an established universe but makes no changes to it")
14:41:33 <b_jonas> and when does that happen in relation to the Baley novels?
14:41:41 <ais523> b_jonas: not sure; those events are mentioned as being in the past in The Caves of Steel
14:41:45 <fizzie> b_jonas: I remember all the details except the name.
14:41:46 <ais523> but they might have happened more than once
14:42:07 <ais523> the book gives the impression that they were a semi-regular occurence
14:42:11 <b_jonas> fizzie: I *don't* remember the details, I never liked that story
14:43:00 <b_jonas> It's clear that Robots and Empire happens after the three Baley novels
14:43:05 <fizzie> I keep getting some of the details mixed up with that other story with Altmayer.
14:43:11 <fizzie> In a Good Cause, I mean.
14:43:45 <fizzie> b_jonas: It's "Mother Earth".
14:44:19 <b_jonas> Mother Earth => http://www.asimovreviews.net/Stories/Story179.html
14:44:28 <b_jonas> that definitely asys it's before The Caves of Steel
14:44:54 <b_jonas> fizzie: is that one connected to the earlier robot stories (of The Complete Robot) somehow?
14:46:54 <fizzie> It doesn't talk very much about robots, so not sure.
14:47:10 <fizzie> There's at least one story that refers back to the Machines in The Evitable Conflict.
14:48:03 <fizzie> And that would be That Thou Art Mindful of Him, included in The Bicentennial Man.
14:48:23 <ais523> for the Machines to be in the same continuity as the Cities and Empire, they'd have to have been fairly flawed, IMO
14:48:25 <fizzie> That's very much out of the continuity that leads to the spacers and all that, I think.
14:49:02 <ais523> given that a major plot point is that they took certain actions specifically to prevent the situation that exists at the start of the City books happening
14:49:29 <ais523> assuming I'm thinking of the right story
14:49:40 <fizzie> That Thou Art Mindful of Him is the one where they stop using human-level robots, turn to small robotic animals to something something ecology (that don't have the Three Laws), but it's all a plot by one of the robots to make sure they will be the superior beings later.
14:50:00 <b_jonas> Ok wait, are the spacers mentioned before Mother Earth, chronologically, like in any of the Complete Robot stories?
14:51:00 <ais523> well they clearly don't exist during the stories that talk about the invention of FTL travel
14:51:05 <fizzie> ais523: That Thou Art Mindful of Him have one version of how we get rid of the Machines, but like I said, I don't think that's on the way to Cities and Empire.
14:51:10 <ais523> and IIRC those are fairly late in the Robot continuity
14:51:34 <fizzie> "Those Machines limited their action of their own accord. Once they had solved the ecological problems that had threatened human society, they phased themselves out. Their own continued existence would, they reasoned, have placed them in the role of a crutch to mankind and, since they felt this would harm human beings, they condemned themselves by the First Law."
14:52:03 <ais523> (fwiw, I suspect that the invention-of-FTL stories /are/ in the Cities and Empire continuity; the FTL gets considerably improved in the meantime but still seems to have the same limitations)
14:52:16 <b_jonas> One thing that ties stuff together is that Susan Calvin is mentioned as a legend in the Foundation, but you can still have a legend or robotics without all the early robot stories actually happening.
14:52:40 <ais523> Calvin is also mentioned in the Cities stories
14:53:07 <ais523> the Spacers are surprised that she came from Earth, even though nothing else would make logical sense
14:53:16 <ais523> (she's dead at that point but still a respected historical figure, and not someone who's had a chance to fade into myth yet)
14:54:23 <b_jonas> I think she's already dead at the time of Mother Earth
14:55:33 <b_jonas> Ok, from this so far it seems like there's two continuities:
14:56:17 <b_jonas> One with all the early robot stories, Susan Calvin, Byerley, the machines, and it ends with Andrew's death.
14:59:22 <b_jonas> And a second with the spacers, that starts with Mother Earth and the spacers having left Earth, separating from humans, Fastolfe builds Daneel and Jander, Sarton uses Daneel and Baley to forward his political goals against Amadiro,
15:00:35 <b_jonas> as told in the Baley trilogy and Robots and Empire, and then the humans leave Earth and Earth becomes radioactive from Amadiro's machinations,
15:03:34 <fizzie> b_jonas: Andrew works on the moon base on prosthetics, and nowhere does it say they're working on FTL; also, Hyper Base (where they did research FTL in the robot stories) is somewhere in the asteroid belt.
15:03:52 <b_jonas> (which is Asimov's greatest retcon, erasing the nuclear wars from ''Pebble in the sky'': there's not many people who dare to remove entire nuclear wars from history, apart from the guys in Eternity and George Lucas)
15:04:36 <ais523> b_jonas: I'm not sure that Pebble in the Sky explains how the world became radioactive
15:05:06 <b_jonas> ais523: isn't it Pebble in the Sky that says it was nuclear wars? maybe it was some other story, Foundation and Earth or something
15:05:13 <b_jonas> I don't remember how that works
15:05:21 <ais523> also I thought that the canon explanation for the radioactivity was that Giskard caused it to happen, and ended up killing himself in the process due to a First Law dilemma
15:05:24 <b_jonas> I like the Robots and Empire version
15:06:12 <b_jonas> ais523: yes, but Giskard was just choosing to stop Daneel from stopping Amadiro, and it was Amadiro who made the machine to make Earth radioactive, but Amadiro did it for evil reasons and lied about it
15:06:47 <ais523> so it was more of a cooperative thing, both Amadiro and Giskard needed to make the decision for it to happen
15:07:06 <b_jonas> or something like that, I'll have to reread Robots and Empire
15:07:29 <b_jonas> I think Amadiro also had a lackey with him but I don't remember who, and possibly a different spelling of his name
15:08:12 <ais523> Vasilia, perhaps? she's female but I know you have pronoun troubles so I'm not relying on the pronouns
15:09:05 <b_jonas> you mean the other character is Vasilia, reused from Robots of Dawn?
15:09:26 <b_jonas> let me check what http://asimovreviews.net/Books/Book328.html says
15:09:47 <b_jonas> I just thought it was a newly introdced character
15:09:50 <ais523> Amadiro orchestrated most of the events of Robots of Dawn, but it was Vasilia who was responsible for actually implementing many of them
15:11:20 <b_jonas> "Amadiro orchestrated most of the events of Robots of Dawn" -- ah yes, no wonder Daneel remembers his friendship with Elijah as good times later in the Foundation. That was back when Daneel wasn't yet orchestrating all the events of human history. Oh to be young and careless and not have the troubles of the whole galaxy on your back!
15:11:48 <b_jonas> The end of Robots and Empire is when he grows up.
15:12:38 <ais523> yes, Daneel had an incredibly low amount of orchestration in Robots of Dawn
15:12:48 <ais523> most of the events were orchestrated by Amadiro, and most of the rest by Baley
15:13:08 <b_jonas> ais523: no no, Giskard took a large part
15:13:15 <b_jonas> in Robots of Dawn especially
15:13:27 <ais523> I'd forgotten that because he was so subtle about it
15:13:46 <ais523> you can effectively treat Giskard and Baley as a single entity there, I guess
15:13:53 <int-e> GG seriously needs red shirts so we know who's going to die ;-)
15:14:00 <b_jonas> and Giskard dies in R and E and explicitly leaves the world in Daneel's care
15:16:10 <ais523> huh, your review site seemed to like The End of Eternity
15:16:23 <ais523> I actually didn't really like that one, I didn't find the setting that compelling
15:16:45 <ais523> (apparently it's part of continuity but given that it manages to retcon all its own events internally, it doesn't really matter whether it is or not)
15:16:54 <b_jonas> ais523: it's not MY review site. it's Jenkins' Guide.
15:17:26 <ais523> well, it's the one you linked to
15:17:29 <ais523> I didn't mean to imply you wrote it
15:18:21 -!- freebot has joined.
15:19:08 <ais523> what sort of bot uses the web interface?
15:19:21 <ais523> maybe it isn't a bot at all
15:20:29 <ais523> oh gah, this is Hofstader's reverse-CAPTCHA situation all over again, isn't it?
15:20:47 <ais523> (when you're unsure whether something is a computer pretending to be a human, or a human pretending to be a computer pretending to be a human)
15:21:03 <ais523> it's actually a very difficult task
15:21:36 <b_jonas> Which web interface is that? Let me check how the cloaks work again
15:22:33 -!- web_jonas has joined.
15:22:59 <ais523> web_jonas: you seem to be identically cloaked to freebot, with the exception of having a different IP
15:23:10 <ais523> (the username appears to be the IP in hexadecimal)
15:23:32 <web_jonas> This one is qwebirc, the one that has the worse interface and requires for a captcha and is ran by freenode themselves
15:23:57 -!- wob_jonas has joined.
15:24:54 <wob_jonas> And this one is kiwiirc, which has better interface, doesn't ask for a captcha, and can connect to any irc server, even one it doesn't know, if you just give it the hostname of the server.
15:25:35 <b_jonas> Ok, so the freenode qwebirc has a cloak with "gateway/web/freenode/", a generic name as if freenode was trying very hard to suggest it's THE only web interface,
15:26:04 <b_jonas> and the kiwi one is cloaked "gateway/web/cgi-irc/kiwiirc.com" which clearly has kiwiirc.com in its name
15:26:12 -!- wob_jonas has quit (Client Quit).
15:26:15 -!- web_jonas has quit (Client Quit).
15:26:20 -!- freebot has quit (Quit: Page closed).
15:26:36 <fizzie> If it's THE only web interface ran by freenode themselves, having "gateway/web/freenode" as the name doesn't sound too generic.
15:28:53 <ais523> huh, freebot appears to be connecting from a hosting company in Croatia
15:28:59 <ais523> which increases the chance that it actually is a bot
15:30:15 <ais523> I got the impression that it was a VPS or web hosting company
15:30:17 <ais523> rather than a consumer ISP
15:30:30 <ais523> which implies that either a bouncer's being used or the connection comes from a server
15:31:03 <ais523> additionally, I'm not aware of any Croatians in the channel, but using a hosting company from another country is not that rare
15:32:03 <b_jonas> there are VPSes in croatia?
15:33:15 <ais523> why wouldn't there be?

15:40:17 <b_jonas> Windows these days lets you type (almost) any unicode character from the keyboard by holding alt and entering its code in decimal on the numpad prefixed by a zero on the numpad.
15:40:43 <b_jonas> But this doesn't help me, because I only remember the character codes in hexadecimal, and don't want to do a radix conversion in my head.
15:41:19 <b_jonas> So I usually start Word, enter the character code in hexadecimal, press alt-x, which enters the character there, then copy-paste the character.
15:41:34 <b_jonas> Is there a saner way to type arbitrary unicode characters on Windows?
15:42:52 <ais523> I don't know of one, but I'm not an expert on Windows
15:43:24 -!- Cale has quit (Remote host closed the connection).
15:46:11 <Jafet> autohotkey script?
15:46:38 <ais523> using autohotkey to fix flaws in Windows is like using m4 to fix flaws in C
15:47:03 <Jafet> ephemerally pragmatic?
15:47:33 <b_jonas> I don't know what autohotkey is. Before you tell me what it is, I have one utterly biased question.
15:47:36 <Jafet> I suppose you could emulate compose sequences too
15:48:52 <b_jonas> Is it one of those things that react to my keypresses with a delay, like the explorer file delete dialog that uses the trash only if you aren't pressing shift at the time when the confirmation dialog box pops up, regardless of whether you pressed delete or shift-delete to delete the file? Like, if I use autohotkey to type characters, will my character appear out of sequence wrt other characters?
15:49:18 <b_jonas> If it's a delayed thing then I don't want to know what it is. If it's not delayed but something like a proper input method, then you may tell me what it is.
15:50:19 <b_jonas> this looks promising => http://www.johndcook.com/blog/2008/08/17/three-ways-to-enter-unicode-characters-in-windows/
15:51:34 <b_jonas> it says there's a magic registry key you can set and then windows has a builtin way. It doesn't mention which version of windows it applies to, probably because it's one of these blogs that never expects you to read anything but the latest entry.
15:52:00 <b_jonas> It's from 2008 and has a screenshot with... um, is that windows xp skin?
15:53:02 <b_jonas> web searched the registry key name mentioned there, leads here => http://answers.microsoft.com/en-us/windows/forum/windows_7-windows_programs/how-to-insert-unicode-characters-like-arrows-using/349b7749-f04b-4ac9-b4b4-ec8461c6f4e5

17:17:52 <\oren\> hmm... i was thinking about how busybox has a single executable for lots of commands
17:21:08 <\oren\> what if you made a language that did that for most tasks
17:22:21 <ais523> \oren\: I have an unpublished joke language that basically works like this: you give it an anarchy golf problem number
17:22:27 <ais523> that has revealed programs
17:22:39 <ais523> then it tries all the programs in the problem number on the user input and gives you the majority output
17:23:14 <ais523> this makes it very good at solving simple well-known problems, unless they're /so/ well-known that the timeout was set to infinity and there are no programs to download
17:24:59 <ais523> the reason this language is unpublished is that it really needs an interpreter
17:25:04 <shachaf> Many anagol problems are underspecified. :-(
17:25:23 <ais523> (possible enhancement: remove programs that are tagged as cheating, give extra weight to programs that are tagged as genuine)
17:25:34 <\oren\> argh, my meeting was just resceduled
17:25:38 <ais523> shachaf: but they tend to be inversely specified by the actual answers
17:28:22 <\oren\> why does schedule have a h in it
17:28:42 <shachaf> you mean why does it have a c in it hth
17:29:42 <shachaf> no, it's pronounced with a "sh" at the beginning
17:29:57 <ais523> I think that varies by accent
17:30:21 <ais523> in some accents it likely starts with an actual sch phoneme (which is more common in German than in English)
17:30:31 <ais523> I've heard both pronunciations I think
17:30:33 <shachaf> if you mean "dj" you should write that
17:32:19 -!- Sgeo_ has joined.
17:33:40 <zzo38> Both pronounce are correct in Canadian.
17:34:16 <zzo38> In British is correct with "sh" and in American is correct without, and in Canadian both ways correct.

17:44:40 <LKoen> are you saying skedjul is not the british pronunciation?
17:51:11 <ais523> "sch" is pronouned very similarly to "sh", and quite differently from "sk"
17:51:28 <ais523> I'm not quite convinced it's identical to an "sh" though
17:58:11 <shachaf> I can hardly hear the difference between them.

23:07:33 <Taneb> Something about affine varieties and algebraic sets
23:07:51 <ais523> `! c printf("Hello, world!\n");
23:08:06 <fizzie> That's the newline problem, I think.
23:08:13 <fizzie> `! c printf("Hello, world!\\n");
23:08:47 <ais523> now I'm trying to figure out what's C-unescaping the input
23:08:57 <fizzie> Well, the thing is, for macros you really need it to.
23:09:07 <fizzie> #define FOO bar \n something(); can't end up on one line.
23:09:15 <ais523> presumably the wrapper that goes around gcccomp
23:09:45 <ais523> the `! c command doesn't seem that broken to me, especially now I added the -lm
23:09:57 <\oren\> fizzie: or we could use a convention where say four spaces or more becomes a newline?
23:10:32 <fizzie> ais523: It still doesn't output any errors.
23:11:01 <\oren\> or we could get tcc and have proper control
23:11:06 <ais523> fizzie: that's because it compiles two programs to see which works
23:11:39 <fizzie> ais523: That's not a good enough reason.
23:11:54 <ais523> right, but it's hard to figure out which set of errors you'd want to show
23:11:56 <ais523> or whether to show both
23:12:14 <fizzie> Personally, I think it should just use simple heuristics to decide which one to compile.
23:12:42 <\oren\> if main appears as symbol in code, compile with main?
23:12:57 <ais523> you need a parser to figure that out, at least a rudimentary one
23:13:09 <ais523> also I think it's a legal local variable name

23:14:07 <ais523> \oren\: oh right, it's legal both ways roudn
23:14:19 <\oren\> because main doesn't have to be a function ebcause fuck fuck fuck fuck
23:14:20 <ais523> a puts call can't appear outside a function

23:18:47 <ais523> \oren\: the version with no semicolon isn't valid as a program in its own right
23:18:59 <fizzie> Incidentally, the program char *main = "Hello, world!"; would generally execute the pointer's value as machine code, not the string literal's contents.
23:19:05 <ais523> the wrapper adds a semicolon at the end (which is harmless if you provided one because ; is a valid command)

23:33:06 <\oren\> basically, you can use #ifdef TMP_MAX\n #error hllo\n #endif to prevent the one that wraps it from being done
23:33:19 <\oren\> `! c char main[]="\xC#";\n #ifdef TMP_MAX\n #error hllo\n #endif
23:33:20 <HackEgo> ./interps/gcccomp/gcccomp: line 53: 308 Segmentation fault /tmp/compiled.$$
23:33:24 <ais523> what does TMP_MAX do anyway?
23:33:26 <\oren\> `! c char main[]="\xC3";\n #ifdef TMP_MAX\n #error hllo\n #endif
23:33:33 <zzo38> The (currently unreleased) FreeUHS catalog utility though will pay attention to ETag and Last-Modified if those headers are present, will handle redirects, a 203 response, and the character set of the response.
23:33:47 <\oren\> ais523: dunno, but I know it's a macro defined in stdio.h
23:34:04 <\oren\> "This macro is the maximum number of unique filenames that the function tmpnam can generate.
23:35:30 <\oren\> `! c printf("%d\\n",TMP_MAX);
23:35:47 <\oren\> `! c printf("%f\\n",TMP_MAX);
23:37:04 -!- oerjan has joined.
23:38:37 <\oren\> `! c printf("%s\\n",tmpnam());
23:38:45 <\oren\> `! c printf("%s\\n",tmpnam(nULL));
23:38:49 <\oren\> `! c printf("%s\\n",tmpnam(NULL));
23:38:55 <\oren\> `! c printf("%s\\n",tmpnam(NULL));
23:39:00 <\oren\> `! c printf("%s\\n",tmpnam(NULL));
23:39:04 <\oren\> `! c printf("%s\\n",tmpnam(NULL));
23:39:09 <\oren\> `! c printf("%s\\n",tmpnam(NULL));
23:39:24 <fizzie> `! c char main[] = "hhi!\\0@\xb7\x01""1\xd2\xb2\x03""1\xc0\xb0\1H\x89\xe6\x0f\x05X\xc3";
23:39:52 <\oren\> so what it's 26 letters, in two cases, and 10 numbers
23:40:21 <\oren\> they oughta use any byte that's usable in a filename
23:40:22 <ais523> fizzie: how much trouble did you go to to write that? :-D
23:40:31 <ais523> also we so need a `! shellcode
23:40:35 <lambdabot> boily said 11h 38m 6s ago: hellørjan. tdh. t!
23:40:46 <ais523> although I'm not sure what format the shellcode would be in
23:40:48 <fizzie> ais523: However much trouble there can fit between the \xc3 one and that. :)
23:41:06 -!- ybden has quit (Quit: Fing).
23:41:11 <fizzie> I did run into a couple of things, like having to do \\0 instead of \0 because GCC doesn't like 0 bytes in string literals.
23:41:23 * oerjan thinks this is a day for quick log skimming
23:41:37 <fizzie> It was surprisingly game for all other kinds of control characters though.
23:41:55 <fizzie> (Assuming those are getting expanded by the same thing that does \n and \0.)
23:43:29 -!- ybden has joined.
23:43:30 <fizzie> Well, that's not exactly proof positive. If the expander left \xc3 untouched, the C compiler would've seen identical sources for those.
23:43:53 <fizzie> `! c printf("%zu", sizeof "\xc3");
23:44:02 <fizzie> `! c printf("%zu", sizeof "\\xc3");
23:44:08 <HackEgo> ./interps/gcccomp/gcccomp: line 53: 310 Segmentation fault /tmp/compiled.$$
23:45:54 <fizzie> Hm, that's a bit more convincing.
23:46:20 -!- Cale has joined.
23:46:26 <fizzie> `! c printf("foo\042);
23:46:37 <fizzie> So no \x, but yes for octal escapes.
23:46:48 <\oren\> is \x a gnu extension?
23:47:30 -!- centrinia has joined.
23:47:34 <\oren\> hmm, maybe the expander is some ad hoc program then
23:47:49 <fizzie> Not in C, but maybe in printf(1).
23:48:03 <fizzie> At least I don't see it in POSIX.
23:48:16 <ais523> it oculd also be echo -e
23:48:26 -!- Zarutian has quit (Quit: Zarutian).
23:48:29 <ais523> I doubt it's printf(1) because % signs would screw that up
23:48:37 <ais523> `! c printf("%s", "Hello, world!");
23:49:01 <fizzie> ais523: Well, I mean, printf "%b" "$@" or some such.
23:49:40 <ais523> `` printf "%b" "n\nt\tx\x22o\042e"
23:49:56 <ais523> printf %b seems to understand both hex and octal escapes
23:50:03 <fizzie> Not the POSIX one, though.
23:50:12 <fizzie> But yeah, HackEgo's does.
23:50:14 <ais523> `` env POSIXLY_CORRECT=1 printf "%b" "n\nt\tx\x22o\042e"
23:50:33 <fizzie> "The interpretation of a <backslash> followed by any other sequence of characters is unspecified", so it's arguably POSIXLY_CORRECT to do that.
23:51:27 <ais523> huh, \c is a pretty weird escape
23:51:54 <ais523> is it even possible to define what that would do in a C source file? I guess it'd just end the file right there, closing any balanced groups that need closing
23:53:20 <\oren\> `! c printf("\u0022");
23:53:43 <\oren\> `` printf '%b' '\u0022'
23:54:21 <ais523> so, is printf(1) Turing-complete? I know printf(3) is
23:54:35 <ais523> (you use %n exploits in order to get it to overwrite its own internal state)
