01:08:31 <Jafet> I doubt you will get more than a definnitive answer here.
01:09:46 <oerjan> for households in norway, i think almost nonexistent.

01:11:02 <oerjan> but maybe it's changed recently for environmental reasons, e.g. my new apartment has water-based heating.
01:11:57 <oerjan> ok it's somewhat fashionable for barbecues, at least :P
01:12:27 <oerjan> that's a recent development.
01:13:08 <oerjan> also for camping and summer houses it may be more common.

04:26:34 <comex> elliott: i was wondering if there is a more precise term.
04:26:41 <comex> i gave a reasonably precise definition
04:27:57 <elliott> finite state machine? :P
04:28:17 <oerjan> very practical, those
04:29:21 <comex> uh... no, not a finite state machine. the idea is to be able to compute an arbitrary function that uses a large amount of memory
04:29:46 <comex> (you *can* simulate a FSM for a fixed number of steps without difficulty)
04:30:13 <Bike> c++. right.
04:30:28 <Bike> oh hey, it's not template garbage
04:30:48 <comex> pretty much is, actually
04:36:49 <comex> (and you can simulate an algorithm that uses a small amount of memory, but may be very difficult to analyze, such as an cryptographic hash, again without difficulty)

06:48:10 <Gracenotes> via Wikipedia: The 1954 edition of the Grove Dictionary of Music and Musicians notoriously dismissed Rachmaninoff's music as "monotonous in texture ... consist[ing] mainly of artificial and gushing tunes" and predicted that his popular success was "not likely to last". To this, Harold C. Schonberg, in his Lives of the Great Composers, responded, "It is one of the most outrageously snobbish and even stupid statements ever to be found in a work that is s

07:10:45 <Jafet> Most popular music consists of artificial and gushing tunes.
07:10:58 <Jafet> Rachmaninov was merely pragmatic.

08:33:56 <Taneb> Well, it must be a secret
08:34:17 <shachaf> Maybe because he doesn't reveal other people's secrets.
08:34:39 <FreeFull> Not a very big secret when it's posted in the wide open
08:35:34 <Taneb> And FreeFull that's just a sequence of silly faces

08:37:24 <Taneb> My god
08:38:03 <FreeFull> Do you see it now?
08:38:17 <Taneb> :P
08:38:25 <FreeFull> You must elope with oklopol
08:38:28 <FreeFull> It's the only way
08:38:29 <shachaf> That decryption function looks kind of contrived.
08:38:46 <shachaf> You could make any message appear in that text with a sufficiently complicated decryption function.
08:38:49 <Taneb> But he's in the far away land of far away
08:39:05 <Taneb> And shachaf raises a very good point
08:39:10 <shachaf> > filter (\_ -> "ILOVEMONOIDSTHEYARESOEASY") ":T :A :N :E :B :I :S :E :C :R :E :T :L :Y :L :O :V :E :Y :O :U"
08:39:10 <lambdabot> Couldn't match expected type `GHC.Types.Bool'
08:39:10 <lambdabot> with actual type...
08:39:18 <shachaf> Er.

08:39:20 <lambdabot> "ILOVEMONOIDSTHEYARESOEASY"
08:39:38 <Taneb> I'd say that that decryption function is much simpler
08:40:01 <shachaf> > map length ["filter (\\x -> x /= ':' && x /= ' ')", "(\\_ -> \"ILOVEMONOIDSTHEYARESOEASY\")"]
08:40:03 <lambdabot> [35,35]
08:41:07 <FreeFull> Well, we both have useless spaces
08:41:11 <FreeFull> Let's get rid of those
08:41:18 <shachaf> Stop nitpicking.
08:41:33 <FreeFull> Well, stop pitnicking.
08:42:39 <shachaf> Anyway I'm not sure what "tane bisec retlyl ovey ou" even means.
08:42:55 <shachaf> Looks like gibberish to me.
08:43:01 <shachaf> Taneb: Wouldn't you agree?
08:43:02 <Taneb> shachaf, isn't "ovey" an exclamation associated with the Yiddish community?
08:43:35 <Taneb> And "bisec" could be short for "bisection"
08:43:43 <shachaf> `? Taneb
08:43:45 <HackEgo> Taneb is not elliott, no matter who you ask. He also isn't a rabbi although he has pretended in the past. He has at least two backup keyboards. (see also: d-modules)
08:43:48 <shachaf> Not very convincing.
08:44:00 <Taneb> Maybe it's "tan e" rather than "tane"

13:19:15 <boily> do you know of a cheap IR camera that I could rig to my box?
13:20:22 <zzo38> No, I don't know about that.

13:35:06 <zzo38> Oops...
13:35:11 <zzo38> Well, here it is: http://hackiki.org/wiki/uselessness_rpg_1,,main
13:37:34 <boily> ~duck yuggo
13:37:34 <metasepia> --- No relevant information
13:38:18 <zzo38> Yuggo is a currency from CthulhuMUD. Zorkmid is a currency from Zork, and also used in some chess variants. Yen is Japanese currency.
13:38:46 <zzo38> (Have you seen such chess variants?)
13:39:23 <boily> I knew about nethack and zorkmids, but chess variants?
13:39:40 <boily> yen is yen is yen. it goes with calpis and pocari sweat and ramune.
13:40:32 <zzo38> Yes, even in some chess variants, mention zorkmids. That isn't important for the purpose of this game, though; I just used three currencies found elsewhere, and since exchange rates vary they don't even need to be matching anything else.
13:43:09 <boily> the log in as a google account is a little bit buggy, but seems to work. there's a PHP error when you click on the google link, then it says “You are logged in as https://www.google.com/accounts/o8/id?id=[RANDOM STUFF]”.
13:43:54 <zzo38> boily: Tell Gregor; that isn't my problem.
13:44:12 <zzo38> It is either Gregor or Google who has done something wrong; probably Google.
13:44:19 <boily> Gregor: what I zzo38ly said ↑
13:47:29 <zzo38> (Specifically, yuggo was the currency used in most shops and vending machines in Pluto I have seen in that game; the exceptions are the bank and Dr.Tkikt which you must both pay for services in copper coins instead; the bank will exchange them automatically though so it doesn't matter. Most of things I have seen about zorkmid are about chess variants, in fact!!)
13:48:07 <zzo38> (Many games might have the different currency being copper, silver, gold; I want to make the game different, so instead I have yen, yuggo, zorkmid. Maybe "yen" might be changed just because it starts with "y".)
13:48:38 <zzo38> (It is true; if I change it, that is the only reason.)
13:48:46 <boily> about that y point, I added an annotation.
13:49:08 <boily> (my wiki editing skills are poor, so the format may not be standard compliant, fsvo standard)
13:49:11 <zzo38> OK, let me see
13:49:49 <boily> fungot: do you have any y points?
13:49:50 <fungot> boily: will you and hurried here. gogah... make... .....don't ever make marlene...
13:52:38 <zzo38> boily: Good point; I won't use this in Z-machine though (another problem is the way Unicode deals with font width)
13:58:58 <boily> 'tis sad. gargoyle seems to have stopped development.
13:59:19 <zzo38> boily: What is that?
13:59:38 <boily> http://ccxvii.net/gargoyle/
14:00:21 <boily> I remember losing a few hours of my life trying to find a lost pig.
14:00:34 <zzo38> O, I have seen that
14:00:55 <zzo38> There are many Z-machine interpreters, but most of them seem very defective.
14:02:12 <zzo38> I have written two Z-machine programs, and I have tested many interpreters; only Aimfiz and Infocom's interpreter run them correctly.
14:03:51 <zzo38> A version of Gargoyle based on Aimfiz instead of Frotz might work.

19:06:45 <boily> only in computer programming you can exclaim “It works! I get the correct error!” and be proud of your work.
19:06:56 <Bike> what about approximation theory
19:08:05 <boily> ~duck approximation theory
19:08:05 <metasepia> In mathematics, approximation theory is concerned with how functions can best be approximated with simpler functions, and with quantitatively characterizing the errors introduced thereby.
19:08:29 <boily> oh. right.
19:08:43 <Bike> or statistics
19:08:45 <boily> well, I guess I was close enough, and within an acceptable error margin.
19:09:07 <boily> Bike: I deny the existence of statistics, based on personal experience.
19:09:11 <olsner> for e.g. compilers, getting the right error is a really important part of what it does
19:10:04 <boily> there's this complete memory blank in my head when I try to recall my statistics classes. I think it was caused by a nerve gas deployed by the dean to keep us students in track and coöperative.
19:11:03 <olsner> hint: a more efficient way to not remember statistics is to not learn it in the first place
19:12:34 <kmc> rustc has 753 "this should fail to compile with error X" test cases
19:12:59 <olsner> that sounds quite few

19:22:33 <boily> well, two and a half. there's an extension cord in my kitchen because I lack well-placed outlets, and have none in my bathroom.
19:22:56 * boily recalls the weeks I had to shave without a mirror... it was a life experience
19:24:53 <fizzie> Personally I think I'd rather go with the cable than with some sort of wifi audio streaming apparatus, those things are always so stupef.

19:27:18 <fizzie> Heh, that's very similar. I have a karman/hard-on (or w/e) amp and two "Jamo Power 130S"es that date probably to the 1970s, inherited from my father.
19:28:06 <olsner> hmm... if the wifi router is connected by cable, does that make the so-called "wireless" non-wireless?

19:35:54 <olsner> I suspect that's something you imagine based on knowing that they are french

19:38:03 <Bike> yeah that one
19:38:08 <elliott> (I haven't heard the album)
19:38:11 <Bike> i thought the monologue was about guitarism
19:38:29 <olsner> the moroder is not one of the daft punk guys though?

20:29:33 <tswett> The naive linear algorithm, which doesn't work, is to step through the haystack, and keep a counter of the number of characters of the needle that have matched. If you encounter a mismatch, reset it to zero.

20:33:39 <^v> yea like malboge
20:35:07 <boily> we should poisson the hispanophones that randomly join this channel in order to predict when will the next one appear.
20:36:38 <Taneb> Reading the t's and c's for student loads...
20:40:32 <kmc> loans?
20:41:05 <tswett> I want to try to think of another Turing tarpit...
20:41:35 <Taneb> No, loads
20:41:39 <kmc> what's a loads
20:41:56 <Taneb> It's how much luggage I'll be able to carry as a student
20:42:03 <tswett> How about this. Memory consists of a bunch of 32-bit words. The instruction pointer points to a pair of words.
20:42:48 <tswett> Then, lemme see.
20:43:09 <^v> hmm
20:43:18 <^v> sould i use FCS32 instead of CRC32?
20:43:22 <Taneb> kmc, yes, I did mean loans
20:43:30 <^v> CRC is too easy to crack
20:44:23 <olsner> tswett: so far this is sounding pretty normal
20:44:48 <boily> Taneb: going to university?
20:44:50 <Taneb> Yeah
20:44:53 <Taneb> Why is life this scary
20:44:57 <tswett> Each execution step consists of multiplying the two words together, setting the second word to the result, and moving right if the result was greater than 991197253, and left otherwise.
20:45:08 <boily> tswett: this sounds like a segment/address pair on an x86 architecture...
20:45:17 <boily> or, as you said, probably not.
20:45:21 -!- Nisstyre-laptop has changed nick to Nisstyre.
20:47:11 <boily> Taneb: disproportionate retaliation from former students who had to endure a little bit less scariness than what you're going to suffer, culminating in an intergenerational serial escalation of standardised, civilised terror.
20:48:20 <Taneb> It's all "If you're Welsh and applying before September 2012... If you're Welsh and applying after September 2012... If you are studying a part-time course..." aaah
20:50:28 <Taneb> "You will need to give employers either a P45 form or a P46 form."
20:50:32 <olsner> what happens if you're welsh and apply during september 2012?
20:50:54 <boily> raise WelshPointerException();
20:50:59 <olsner> ("Become welsh and find out!")
20:52:08 <Taneb> The UK is a weird country
20:52:26 <^v> UK isnt a country .-.
20:52:36 <Bike> your mom isn't a country
20:53:37 <boily> if google translate is right, it may be a EithriadPwyntyddNull(). I'll have that in my code next time I have to do java.
20:55:41 <olsner> is the ll in null pronounced the welsh way there?
20:56:11 * boily tries it out... «nuthllhthhhh»
20:58:53 <olsner> think nutlh in Klingon
20:59:33 * boily frowns and shouts «nuTLH!!!»
21:02:26 <olsner> perhaps you could use nullity = dirymedd instead: EithriadPwyntyddDirymedd()
21:04:02 <boily> ooooh, much better!
21:05:54 <olsner> the word "pwyntydd" feels very welsh, filled with welshness
21:07:53 <Phantom_Hoover> ^v, yes it... is

21:08:35 <Phantom_Hoover> Taneb, ooh, are you wrangling with university interfaces
21:08:57 <Taneb> I'm wrangling with some part of the government, I belive
21:09:00 <Taneb> *believe
21:09:02 <Taneb> Not sure which
21:09:16 <Phantom_Hoover> (currently i'm trying to apply for student funding for the next year only to be informed that the service is broken)
21:09:39 <elliott> Phantom_Hoover: the UK is a sovereign state but not a country I think?
21:09:48 <elliott> Scotland, England and Wales are the countries
21:10:11 <Phantom_Hoover> oh christ, i forgot about that stuff
21:10:12 <boily> Taneb: good luck. I had to fill out a government form this summer where I was repeatedly asked if I'm a fisherman.
21:10:21 <Taneb> Are you?
21:10:28 <boily> absolutely not.
21:10:31 <shachaf> elliott: wikipedia calls it a country a little bit
21:10:47 <Taneb> The countriness of the United Kingdom is part of its weirdness
21:10:51 <boily> Taneb: I'm an IT professional.
21:10:52 <Phantom_Hoover> previously when i was filling out the form it was demanding my parents' income despite the fact that i'd already clearly exempted myself from the means-tested stuff
21:11:01 <Taneb> boily, are you a phisherman?
21:11:35 <boily> Taneb: never phished nobody. I prefer more subtly direct ways of extracting valuable information from people, like with the The Question.
21:11:56 <Taneb> Did you know that Hexham is precisely half-way between Edinburgh and York
21:12:00 <Taneb> I think I mentioned that earlier
21:12:01 <shachaf> boily: What's subtle about that?
21:12:10 <boily> btw, ^v, what are your approximate geographic coördinates and body weigh?
21:12:22 <^v> 300 and USA
21:12:29 <boily> shachaf: subtly direct, not subtle.
21:12:40 <shachaf> Yes. What's subtle about the directness?
21:12:56 <boily> nice to see that ^v is keeping with the spirit of the channel by providing completely useless answers to the question.
21:13:10 <Phantom_Hoover> well they hardly weigh 300 kilos
21:13:40 <Phantom_Hoover> you'd have to be made out of metal or something for that
21:13:41 <boily> shachaf: see, I was subtle there. it's missing some IRL experience as it is transmitted through a textual medium, but trust me, it is subtle.

21:13:50 <elliott> was the . bolded
21:13:58 <boily> elliott: no.
21:14:01 <Phantom_Hoover> yes
21:14:01 <olsner> ooh, "Is there a Little/Lesser Britain?" ... as far as I can recall, it has never occurred to me that there would be another britain
21:14:04 <Fiora> Phantom_Hoover: I'm now imagining someone named "Doc Osmium"
21:14:07 <Phantom_Hoover> .
21:14:10 <Phantom_Hoover> no
21:14:27 <elliott> Doc Osmium is a good suppervillain name
21:14:31 <Taneb> olsner, there was the Roman province of Britannia Minor, corresponding roughly to modern England
21:14:32 <elliott> (decided not to correct that typo)
21:14:33 <Taneb> I think
21:14:50 <Phantom_Hoover> if i was a supervillain i'd be doc osmium
21:14:57 <boily> elliott: oh, it was perfectly voluntary. I dislike bolded punctation marks.
21:15:08 <Phantom_Hoover> i'd kill people by hitting them with osmium i guess
21:15:18 <fizzie> boily: :)
21:15:18 <olsner> Taneb: hmm, that page pointed to the piece of france that's called (roughly) "Britain"
21:15:20 <Taneb> Oh wait, it's Brittany in France
21:15:30 <Taneb> Yeah
21:16:00 <boily> fizzie: you fıend.
21:16:03 <Phantom_Hoover> fizzie, there's a certain intensity to that smiley
21:16:05 <Phantom_Hoover> i like it
21:16:58 <Taneb> It stares into your soul
21:17:13 <mnoqy> :)
21:17:20 <shachaf> mnoqy: hi
21:17:29 <Phantom_Hoover> ;_;
21:17:33 <shachaf> looking forward to this evening??
21:17:35 <Phantom_Hoover> i won't lie
21:17:37 <Phantom_Hoover> i wept
21:17:44 <mnoqy> shachaf: sure?
21:18:11 <mnoqy> nothing on tuesday :( or wednesday :(
21:18:42 <olsner> shachaf: what's with this evening?
21:19:09 <shachaf> mnoqy: oh no did he miss the tuesday update?
21:19:22 <mnoqy> it seems so
21:21:46 <Phantom_Hoover> shachaf, so like is this a sex thing
21:22:08 <shachaf> what isn't, these days
21:25:11 <boily> people from #esoteric meeting IRL??? the apocalypse has come!
21:25:23 <Phantom_Hoover> get w/ the program
21:25:39 <olsner> boily: the apocalypse has been here all along
21:25:40 <Phantom_Hoover> a) that's been happening since forever in finland, but also b) the apocalypse is only with elliott and Taneb
21:26:21 <boily> oh. wasn't there a Canadian corollary or something about that?
21:26:23 <Taneb> I almost met ais523 once
21:28:46 <Taneb> But I did not
21:29:03 <Taneb> Hey, are there any esolangers in or around York?
21:29:17 <shachaf> (>>>), maybe?
21:29:19 <shachaf> Er.
21:29:20 <shachaf> does New York count
21:29:24 <olsner> Taneb: are you moving out of hexham?
21:29:31 <Taneb> olsner, in October
21:29:37 <Taneb> shachaf, slightly not
21:29:43 <shachaf> But mostly?
21:29:53 <Taneb> Mostly still not
21:30:01 <shachaf> A little bit?
21:30:09 <Taneb> Not really
21:30:29 <Taneb> It's more like Birmingham than New York
21:30:33 <shachaf> How slight is this slightly?
21:30:43 <olsner> Taneb: nice, good luck with the unhexhamming
21:30:54 <nooodl> shachaf: hi good nooodl-question-answering here
21:31:14 <shachaf> nooodl: ????
21:31:18 <shachaf> what did i do
21:31:26 <Taneb> shachaf, slightly may have been used here to mean entirely
21:31:29 <nooodl> <shachaf> (>>>), maybe?
21:31:30 <shachaf> oh
21:31:36 <shachaf> that was my touchpad talking

22:05:07 -!- carado_ has quit (Ping timeout: 246 seconds).
22:06:56 <kmc> it's... easier than it sounds, once you find the magic bit of janky research code that generates MD5 collision pairs
22:07:15 <boily> ~duck janky
22:07:15 <metasepia> Software description: continuous integration server built on top of Jenkins and Hubot (Ruby).
22:07:24 <Fiora> when the generating md5 collisions become that easy?
22:07:25 <kmc> I think I used http://www.win.tue.nl/hashclash/
22:07:28 <boily> bletch. the horror.
22:07:34 <Fiora> I'm now thinking of um... valerie's article on the hash function lifetime thing
22:07:44 <kmc> yeah
22:07:56 <kmc> sounds like when = 2007?
22:08:15 <Fiora> hmmm... so like, preimage finding is still generally hard and hasn't happened for most hashes, right?
22:08:26 <kmc> anyway you can find maybe a dozen collision pairs per hour on a pretty modest machine
22:08:30 <Fiora> but like, how hard is finding a partial preimage? like "I want a hash that's 00000000000000***********"
22:08:37 <Fiora> is that potentially easier than like, an actual preimage?
22:08:52 <kmc> chosen-prefix collisions are feasible too, now, with big but not absurdly big compute farms
22:08:56 <kmc> http://en.wikipedia.org/wiki/Collision_attack#Chosen-prefix_collision_attack
22:09:11 <Fiora> no, I meant like, the *hash result* has a chosen prefix
22:09:14 <kmc> yeah I know
22:09:17 <kmc> I was just following what I said
22:09:20 <Fiora> ohhh, I see
22:09:34 <Fiora> "A real-world collision attack was published in December 2008 when a group of security researchers published a forged X.509 signing certificate" wow
22:09:55 <shachaf> It's not easy enough for that Typeable bug. :-(
22:09:56 <kmc> also the Flame malware used a chosen prefix collision, following a technique that is not published in the open literature
22:10:03 <Fiora> wow @_@
22:10:10 <kmc> which basically demonstrates that it was made by someone who employs world class cryptanalysts
22:10:22 <kmc> it's kind of like poisoning someone with a rare isotope of polonium...

22:11:20 <kmc> these are some pretty badass job titles really... "secret untier", "secret writer", "secret studier"
22:11:35 <kmc> anyway I don't know of any practical significant preimage attacks on MD5
22:11:47 <kmc> there are theoretical faster-than-brute-force attacks
22:12:09 <Fiora> I guess I was thinking, like, valerie wrote the thing about how hash functions have a finite lifetime and you have to be prepared to upgrade
22:12:17 <kmc> those tend to exist for most hash functions, even ones considered OK
22:12:21 <kmc> maybe only with reduced rounds though
22:12:23 <Fiora> and was kind of thinking what would happen if SHA-256 got a break and suddenly bitcoin collapsed
22:12:35 <kmc> heh
22:12:37 -!- augur has joined.
22:13:04 <shachaf> there are surely more likely scenarios for that than people breaking sha-256
22:13:06 <kmc> is that more or less likely than an efficient algorithm for discrete logarithm problem on elliptic curves?
22:13:10 <kmc> probably more likely
22:13:15 <kmc> it would have different consequences too though
22:14:11 <Fiora> like, breaking ECDSA?
22:14:15 <kmc> yeah
22:14:29 <Fiora> geez if you could brea that you could like, forge signatures, right?
22:14:39 <kmc> yep you could steal anyone's bitcoins
22:14:54 <Fiora> wow
22:14:59 <Fiora> well, I mean, in general, right?
22:15:00 <kmc> let's build a quantum computer and use it to steal all the bitcoins
22:15:03 <Fiora> like, other kinds of signatures
22:15:05 <kmc> sure
22:15:09 <kmc> it would be a huge deal
22:15:29 <kmc> i wonder if there are any altcoins using post-quantum signatures yet
22:16:56 <shachaf> maybe someone already broke it but they're being discreet about it
22:17:45 <shachaf> alt.coins
22:18:10 <kmc> is that a joke about discreet logarithms
22:18:21 <shachaf> maybe
22:18:47 <Fiora> how do you get lumber down the river without anyone noticing
22:18:50 <Fiora> send it as discreet logs
22:18:54 <kmc> >_>
22:19:32 <kmc> I think there was an episode of NUMB3RS where the guy breaks All The Crypto and then the mafia is after him or something
22:19:52 <shachaf> Fiora: you could build log tables with it
22:19:59 <kmc> yeah here we go "A young girl is kidnapped, but her parents refuse to cooperate with Don's investigation. The girl's father is a mathematician, and the kidnapping may be related to his work on the Riemann hypothesis."
22:20:13 <kmc> episode title "Prime Suspect" (i'm not making this up)
22:20:16 <shachaf> good hypothesis
22:20:30 <Fiora> that's that's terrible
22:20:34 <Fiora> that's so bad.
22:20:44 <kmc> the whole show is like that
22:20:56 <kmc> it's terrible but I enjoy watching it because it was filmed partially at my school
22:21:07 <kmc> so I'm like "hey I know that building, it's actually much easier to break into than that"
22:21:11 <Fiora> it must really cater to the lowest common denominator
22:21:33 <kmc> >_>_>_>_>
22:21:47 <fizzie> Fiora: That's that's terrible.

22:39:34 <kmc> I was watching NCIS and they had to shut down the computer in time to disable the bomb or whatever but the guy couldn't figure out the interface so at the last second he just shot it a bunch of times with his gun

22:50:35 <kmc> they do have a discount railcard for students
