asciilifeform: but if thing tasted as good as the tube smelled!
mircea_popescu: lel. good for granpa then.
asciilifeform: oh it was empty tube
mircea_popescu: but yeah, should be smoked within the same decade they're rolled. tobacco dun exactly age in this extended sense
asciilifeform: 20 yrs ago it still had the smell. ( not today )
asciilifeform: hilariously, asciilifeform has a 'romeo&juliet' cigar tube from 1970s
mircea_popescu: and in other ways and means, i just bought a pile of primo cigars, presidents and romeo y juliets and whatnot at this... cathouse, basically. ☟︎
mircea_popescu: asciilifeform no but that's the point, base 10 is superbly built wrt primeness.
asciilifeform: it ain't as if you're ever getting a prime from prime+prime, tho
mircea_popescu: in other bases that don't so even split, this is not crypto-valuable because you would get induced lean.
mircea_popescu: anyway, the above example of "alt-addition" is mostly based on the happenstance that in base 10, the set of digits that are also prime is {1,2, 3, 5, 7} and the set of digits that are not prime is {0, 4, 6, 8, 9} ie it just so happens to be a perfectly balanced split. ☟︎
asciilifeform: folx with 'infinite' resources, turns out, can't afford some very basic things.
a111: Logged on 2017-02-19 03:54 asciilifeform: (iirc we had a thread where i described how corporate ameritards, if given a problem like phuctor, would happily soak up a few $mil and megawatt of iron)
mircea_popescu: wtf out of, tree trunks ?
a111: Logged on 2017-09-20 19:19 ben_vulpes: and as the keccacteams mention, little incentive for cryptoacademia to formalize how ARXceteras might fall over. hard work with little guarantee of payout apparently terrible strategy in a world of publishorperish + everyone pretends to ignore that none of the academics ever bothered to do the hard work of an actual ffa, preferring instead cheap outs like leaky tables
mircea_popescu: http://btcbase.org/log/2017-09-20#1716136 << the truth of the matter is that no fiat pretend sovereign CAN AFFORD to do such work. because they are poor. it's like asking why easter islandians didn't build pyramids. ☝︎
shinohai: lobbes: There are like 30 instances of it over in #eulora
asciilifeform: it's a triviality: if you have 1 , you can make the other out of it with ~no effort
mircea_popescu: asciilifeform i seem to unspecifically recall this
mircea_popescu: let's do this fucking properly.
asciilifeform: incidentally iirc we did the proof of 'if there is a good hash, there is a good blockcipher, and vice-versa' ☟︎☟︎
mircea_popescu: i also fucked it up because 9 is not prime so it should have carried the 1
mircea_popescu: and the whole point was to break out of ring.
mircea_popescu: association it does not tho.
asciilifeform: mircea_popescu: lookx to me like your addition dun commute ( or associate... ) ☟︎
lobbes: fuck. I apologize for lobbesbot's join/part spam lately. no idea wtf is happening. taking him out of chan for time-being...
mircea_popescu: i was not proceding towards a purpose! but it is worth pointing out that the addition understood in terms of "sum+bit diddle" can readily be extended ; and probably should be.
asciilifeform: i'd prefer a macroscale numbertheoretical hash, even one that explicitly stands on strength of, e.g., rsa, to the currently extant soup.
mircea_popescu: just illustrating the concept.
asciilifeform: then it'll be a table
mircea_popescu: asciilifeform per digit tho
asciilifeform: mircea_popescu: anything involving 'isprime()' during everyday life is either a table lookup (leaks!) or miller-rabin (slow as fuck, temptation to cut iterations and introduce eggog)
mircea_popescu: addition is "and you flip a bit if and only if the digits overflow the mod", but this is historical accident.
mircea_popescu: there's a whole class of generalizations that can be done in this same vein.
mircea_popescu: consider something like mp's generalized addition : the sum of two numbers flips a bit if and only if one of them is prime.
mircea_popescu: while the carry property of addition is cryptographically valuable, it'd be better to use a general transform with bit coda instead.
ben_vulpes: and as the keccacteams mention, little incentive for cryptoacademia to formalize how ARXceteras might fall over. hard work with little guarantee of payout apparently terrible strategy in a world of publishorperish + everyone pretends to ignore that none of the academics ever bothered to do the hard work of an actual ffa, preferring instead cheap outs like leaky tables ☟︎
asciilifeform: and imho there is a serious problem with 'not ARX' in linked piece : omitting additions makes the hash ~considerably~ nsa-friendlier : it is easier to implement xor/and/not/shift on, e.g., optical computer, when you don't need addition (and ergo carries)
asciilifeform: ( plenty of known basis for ~weaknesses~ of various . the absence of which, in any particular case, has NO bearing on above. )
TomServo: asciilifeform: I recall you mentioning this.
asciilifeform: TomServo: there is no scientific basis for the strength of ANY published hash algo whatsoever.
asciilifeform: http://wotpaste.cascadianhacker.com/pastes/s0ZSW/?raw=true << plain txt
TomServo: archive.is seems to be struggling with it.
TomServo: Ahoy, just wanted to pass this along: https://keccak.team/2017/not_arx.html
asciilifeform: !!up TomServo
asciilifeform: bonus lul: https://archive.is/tK1o1 << list of public catastrophic bugs in bigint libs . bonus-2 : compiled by the perpetrators of mit's attempt at faux-ffa ( won't link separately, it's a megalith of mechanical 'proof' crapolade )
asciilifeform: ( ...handwaves!1!11!... ) this sums to a potential 25% saving of clock , if finessed.
asciilifeform: there are a total of Bitness * DividendWordness cycles , in this example 64*128 == 8192
asciilifeform: it isn't actually necessary to touch the entire R for the first Bitness*(RemainderWordness-1) (on 64-bit box, and for the 4096b example, that's 64*63 == 4032 ) shots of the inner loop !
asciilifeform: ( hint re FZ_Mod : notice that the first Bitness shift-lefts are really single-word; and same is true of the subtraction, and of the mux; the next Bitness ditto and ditto -- are really 2-word ops; and so on. )
asciilifeform: i ain't linking to pediwikian bowdlerizations , and there is no other source afaik .
asciilifeform: barrett reduction >> http://www.loper-os.org/pub/barrett_1986.pdf << 1333337 w4r3z . yes, pdf, it's the original 1986 article, scan.
asciilifeform: ( the 'corrector' at the end of barrett will have to go through a mux, and fire a fixed # of times, and gotta prove that this-many and no-greater suffices. )
asciilifeform: but i will need an ironclad proof that it worx for ALL possible inputs.
asciilifeform: with barrett, modexp should go back to below-1sec @ 4096b .
asciilifeform: ultimately it would make sense to use barrett reduction but currently i am not satisfied with the proof that it converges ( for some reason, every statement of this proof that i could find, seems to exclude reduction by powers of 2, and i do not yet understand why )
asciilifeform: all of this - naturally - remains properly constantspacetime and unrollable.
asciilifeform: alert reader will also notice that FZ_Mod is now ok with half-width divisors, eliminating the copying in FZ_Mod_Mul and FZ_Mod_Square .
asciilifeform: ^ no barrett yet. and there is still room for polish in barrettless variant, there is still a great deal of avoidable shifting and subtraction of guaranteed-empty words in FZ_Mod ( exercise for alert reader, to see where ! )
jhvh1: ben_vulpes: The operation succeeded.
ben_vulpes: !~later tell mircea_popescu "university of electronic science and technology of china"
shinohai: !~later tell lobbes You're gonna hafta to tell me the story of this one over a beer one day. [~]D
mircea_popescu: yes "anticolonialism" was bullshit, but not because it destroyed a supposed rational approach of the colonisers. it was bullshit because it exactly mirrored "civil rights" at home, ie was driven by INTERnationalistic, socialist elite-wannabes.
mircea_popescu: BingoBoingo check out the libertards stealing the having stolen !
BingoBoingo: “Anticolonialism ravaged countries as nationalist elites mobilized illiterate populations with appeals to destroy the market economies, pluralistic and constitutional polities, and rational policy processes of European colonizers.”
ben_vulpes: http://logs.bvulpes.com/trilema?d=2017-9-14#205675 << i have a line open to "UESTC" in chengdu, i'll keep y'all in the loop
ben_vulpes: "i'm cultured, i had a stool transplant!"
a111: Logged on 2017-09-20 02:47 mircea_popescu: soo, given the "cultured milk" yoghurt bs these days, i wonder what % of us population's entire exposure to that concept is in that context, and as a result has come to believe "cultured" means you know, you've had some germs injected or something.
BingoBoingo: http://btcbase.org/log/2017-09-20#1716033 << 50/50 between that and people thinking germ injection is fancy ☝︎
BingoBoingo: and the discussion is over the same qntra piece, submitted to the alt-Reddit with the same title to samely title /conspiracy
BingoBoingo: The jew media is the jew media
BingoBoingo: The Seattle mayor is the pedosexual
BingoBoingo: Well, even the top comment is better: "“But why would you want to offend this poor, oppressed pedosexual, you bigot? You’re just pedophobic!” – jewish media"
mircea_popescu: i mean... is that even legal ?!
mircea_popescu: i don't think you're allowed to use votes that way.
BingoBoingo: The upvoats don't lie. Reddit's been eclipsed hard by the conspirator community
BingoBoingo: Anyway, that was all a fucking setup. Look at the real link aggregation site: https://voat.co/v/Conspiracy/2140102
mircea_popescu: the enjoyable aspect of these empty hollow shells of nothing PURPORTING to be "liberals" or "consumers" or whatever the fuck it is they're purporting to be is that it takes literally 0 effort to parody them into the ground.
mircea_popescu: i have this friend (ie, chick that was dating hotter guys than me in highschool and never sat with me in cafeteria) that's (((being))) a real estate agent except she's not closed on anything since 2015. it'd REALLY make my day if I could introduce her to some beta trading in their govt issued paycheck for a govt issued house certificate.
mircea_popescu: would you like to buy a house together ?
mircea_popescu: sometimes i can't help but think if you didn't have me around to provide grounding you'd end up drifting away into some cult or something BingoBoingo.
BingoBoingo: But Trump spoke to the UN so now he won per the rest of the world nao too
mircea_popescu: that's how you know they're not (((REALLY))) barristas, either. they don't admit to it, right ? so it's not true.
mircea_popescu: hey, she didn't (((REALLY))) lose if they don't admit she has!
BingoBoingo: Right, Just like that 83rd trimester abortion can get the girl's modesty back
mircea_popescu: it's basic, good thinking such as this that saves elections, i'll have you know. goood thing hilarity still has a chance!
BingoBoingo: So it seems. This is just speculation based on observed behavior
mircea_popescu: o wait, are they "protecting their candidate" ?
BingoBoingo: HRC is how they say "Hillary Clinton" in places they don't want google to associate with Hilary Clinton
mircea_popescu: gotta love how teh jews are still out there, acting as if there's more substance to this supposed "liberal" thing than said hilarity.
BingoBoingo: Completely neglecting the whole point of... A couple catholics burried their bishops in little boys and news pushes it decades later
mircea_popescu: what's a hrc ? teh pantsuited hilarity ?
BingoBoingo: "that's barely English, and the only reason "pantsuit" is in there is because of a high correlation with "liberal" thanks to HRC."
mircea_popescu: since when trilema "purports" ?
BingoBoingo: ben_vulpes: That called De Fence
ben_vulpes: don't you know, BingoBoingo, tmsr~ is 95% shannonizer by linecount
BingoBoingo: "Man, that site is weird. There's lots of stories that have the word "pantsuits" in them but the site purports to be about bitcoin."
mircea_popescu: after all, you're not supposed to look anything up, just guess "what it could mean" "in context".
mircea_popescu: soo, given the "cultured milk" yoghurt bs these days, i wonder what % of us population's entire exposure to that concept is in that context, and as a result has come to believe "cultured" means you know, you've had some germs injected or something. ☟︎
mircea_popescu: and now thatthe log is done, i shall dedicate myself to the other enjoyable literate passtime -- the reading of old trilema articles.
