asciilifeform: incidentally i dun think i've put into the logs why montgomery's modular mult algo is unusable
asciilifeform: reason is that it demands special forms and therefor is not a general-purpose modexp
asciilifeform: specifically demands that the modulus be odd, and that it must be greater than either multiplicand.
asciilifeform: if either condition is false, it will silently shit out garbage.
asciilifeform: ( the thing is widely used in rsatrons which agree to constrain themselves thusly, but is entirely irrelevant in ffa )
asciilifeform: a*b mod m MUST WORK FOR ALL INTEGERS .
asciilifeform: no 'speshul rsa forms' in ffa.
mircea_popescu: asciilifeform silver dun tarnish lol, there's such a thing as proper silver. and it has low melting point and easy to work and it doesn't grow fungi.
mircea_popescu: and so on.
asciilifeform: it will tarnish when full enough of acidic finger oil.
mircea_popescu: you ever had silverware ?
asciilifeform: sure
mircea_popescu: tarnished ?
asciilifeform: certainly not shiny like scalpel, no.
mircea_popescu: i ate off my great-grandfather's set, still clean as the day in 1870 it was made.,
mircea_popescu: yes well, guess what, your model & kbd is also not like scalpel.
asciilifeform: it would be if stainless
mircea_popescu: surgical steel works at 2700 degrees. silver at 700.
mircea_popescu: silver you can work with hammer ; steel must be drop forged. and so on.
asciilifeform: i was thinking of machining but yes
mircea_popescu: for your actual needs, silver kbd much better than steel, if you're going to go metallic (which, not great idea in first place).
asciilifeform: why not ?
mircea_popescu: because very expensive to work, for instance.
asciilifeform: well thread was re a hypothetical nothing-spared kbd.
asciilifeform: so i'd go for, say, monel.
asciilifeform: dunno if anything'd beat monel.
mircea_popescu: nickel ?
asciilifeform: ugh ever wore a nickel watchband ?
mircea_popescu: i dunno, maybe. i've little experience with the item.
asciilifeform: nickel is prolly the least biocompatible metal
mircea_popescu: but it does share silver qualities, ie easily fabricable.
mircea_popescu: asciilifeform monel is nickel.
mircea_popescu: 2/3 by weight.
asciilifeform: no moar than steel 'is' carbon
mircea_popescu: iron.
mircea_popescu: carbon is 2-3% in steel.
asciilifeform: monel ( and more recent inconel ) is spiffy unreactive nickel alloy, used in aggressive envir (e.g. molten na reactor tubing)
mircea_popescu: a special kind of zamak.
asciilifeform: lol chrome not zinc
mircea_popescu: anyway, doesn't mix well with other metals is its main thing.
asciilifeform: that's quite ok, make whole thing from it
asciilifeform: good enough for tokamak, good enough for kbd...
mircea_popescu: i'd still take silver myself, if i were doing "metal kbd". not that i would.
asciilifeform currently surrounded by tall pile of -- mostly worthless -- literature re mod mult
asciilifeform: srsly, couplea kg worth by nao
asciilifeform: 95% of the academitards dun even bother with any attempt other than 'how do i montgomery slightly faster'
ben_vulpes: i think that i would like wood keys.
ben_vulpes: can even get the inset bit asciilifeform slavers for
asciilifeform: ben_vulpes: how do you propose to make 200+ identical wooden keys with the proper shape ?
asciilifeform: ( and 'redefine the shape' is not an answer )
asciilifeform: how would you make the meniscus ?
ben_vulpes: a mill
shinohai: ben_vulpes http://www.instructables.com/id/WOODEN-KEYBOARD/
asciilifeform: ewwww
ben_vulpes: shinohai: no good
shinohai: (Only good fer Crapplebook Pro)
ben_vulpes: asciilifeform: meniscus also with a mill.
asciilifeform: ben_vulpes: so why wood then
asciilifeform: so that it can get stuck in the piston when humidity goes up 5%
asciilifeform: ?
shinohai: Wait, this is faux keyboard, merely shapes stuck on top of keys
asciilifeform: lol!
ben_vulpes: asciilifeform: why use wood for the piston mating face?
ben_vulpes: granted i have not seen this piston kb design you've mentioned
asciilifeform: ben_vulpes: http://btcbase.org/log/2017-09-12#1712731☝︎

ben_vulpes: oh buckling spring
asciilifeform: yes, that's what a keyboard is
ben_vulpes: you said piston, i was imagining fancy tiny pistons with overpressure valves!
asciilifeform: it dun have to be an actual spring, ftr
asciilifeform: ibm made a magnetically-tensioned kbd at one point
asciilifeform: so long as you get the sproing -- worx
ben_vulpes: point stands, don't use decorative materials for the precision tracks
asciilifeform goes 'wtf, THIS crackpottery of mine - you lot find interesting, but the stubborn boojum that keeps 'p' from happening, not interesting somehow '
asciilifeform: and ftr mircea_popescu your algo takes at least N times more cycles than the classical.
ben_vulpes: i find it very interesting, but do not have anything useful to say on it!
asciilifeform: ( does N subtractions , N nullity tests, and when modulus is maxint ( and therefore at all times ) it reduces to the classical's cost )
mircea_popescu: dude get out, every shape can be made out of wood cheaper and faster than ~any other way except for ABS injection.
asciilifeform: let's ask pete_dushenski if there are wooden gears in his rolex
ben_vulpes: omfg with the moving of goalposts
mircea_popescu: nevermind the rolex. and nevermind "humidity" bs, wood is not pine.
asciilifeform: ironwood would probably work.
mircea_popescu: there are wood painted icons survived fine (ie, no cracks in cunt mary's face) for 1k years.
mircea_popescu: there's all sorts of options in the hardwoods.
asciilifeform: to what stress is the picture frame subject ?
mircea_popescu: humidity varying in open air church.
asciilifeform: but yes i thought about wooden keys. probably would want a custom milling rig to make'em ( something like a lens maker's lathe )
asciilifeform: though i have nfi how one would do the inlay such that surface is smooth to the touch
asciilifeform: presumably you would inlay 1st then cut the meniscus.
mircea_popescu: winder/summer/ and the century floods.
mircea_popescu: and also it's not a matter of " THIS crackpottery of mine - you lot find interesting, but the stubborn boojum". it's a matter of you being more hysterically terrible ad kbd design than at p design.
asciilifeform: i dun actually make keyboards. but did once say 'i'd like a stainless steel kbd' and for some reason the reaction is always 'no have THIS instead'
mircea_popescu: asciilifeform yes, you first inlay then shape. this is how it's done.
shinohai gives asciilifeform cardboard keyboard instead ....
mircea_popescu: asciilifeform because "stainless steel kbd" is an entertainingly stupid notion ; and what's more it's pecularly stupid in the way your stupid works, i can see it relate to the "fuck you guise, ima live on a boat" and so on. spherical cow sorta approach.
asciilifeform: prolly if i desperately wanted custom keys, i'd laser the letters and then cast into acrylic.
mircea_popescu: the people you linked re "here is what dbl injection is" will actually do exactly that for you, also. it's not THAT expensive.
mircea_popescu: superficially it seems like omfg lotta money ; but not so bad. people can afford to make eg icecube trays that retail for 3 bux ie cost a quarter each. how many of those sell ? 10k if you're lucky.
mircea_popescu: hurr durr, you're out 10k for the run.
asciilifeform: low-tech , 'cheap & angry'
asciilifeform: and probably last as long as plastic keys.
asciilifeform: yeah 5-10k usd
asciilifeform: there used to be a club where various folx pooled dough and bought.
asciilifeform: ( it is -- unsuprisingly -- mostly tooling cost )
asciilifeform: *unsurprisingly
mircea_popescu: right.
mircea_popescu: besides, you won't make one, you'll make say 100. because fuck it.
asciilifeform: recently there was even a d00d who had entire model f made this way, in a run of 1000 or so
mircea_popescu: and then after you start using it people fight for it and there.
asciilifeform: but for some odd reason he made a variant without f-keys, arrows, numpad
mircea_popescu: MOST of "branded" consumer items are ~this anyway.
asciilifeform: ~unusable
asciilifeform: https://www.modelfkeyboards.com << linked for compleeetness of thread
mircea_popescu: there's even dedicated "investment" stupid money chasing such "ideas". not as many as there were in the 90s, owing to a lot of unfortunate interactions with various "transhuman" tards past 20 years, but still some.
asciilifeform: ( seems to have variant with numpad nao! but STILL no f- )
mircea_popescu: at any rate if you put an order for keys they'll be relieved. "really, not pens for once ?! holy shit this is the most exciting this job ever got"
asciilifeform: the saving grace is that indeed i and everybody else can get by without ideal modelf kbd. but on the other hand i ~do~ need a modmulter.
asciilifeform: one way or another it will have to appear.
mircea_popescu: myeah.
mircea_popescu: so in the end what was it, http://btcbase.org/log/2017-09-12#1713104 or http://btcbase.org/log/2017-09-12#1713161 ? cuz i don't expect it can be both dubious and well known at the same time.☝︎☝︎
a111: Logged on 2017-09-12 22:20 asciilifeform: i'ma need to find a proof that this holds for all integers.
a111: Logged on 2017-09-12 22:35 asciilifeform: this btw is also in vol2 of knuth
asciilifeform: mircea_popescu: i'm satisfied that it holds, as written. in re knuth, turned out that i was thinking of the 'addition chains' method of mod-exp
asciilifeform: which resembles yours, and doesn't win anything in our case.
mircea_popescu: anyways. i spent some time where the math lives, and i am satisfied that proving some sort of hard relation between fxy=mod(xy) and a polynomial expression of xy is in fact reality-breaking.
mircea_popescu: and consequently won't be forthcoming.
asciilifeform: is what i was trying to get across in the beginning
mircea_popescu: all that's left is little cheats here and there.
mircea_popescu: most of which are verboten by the whole "mechanism" view of things.
asciilifeform: correct
mircea_popescu: so, want a frog you can kiss into housekeeper&cocksucker all you want, for all the good'll do ye.
asciilifeform: ( incidentally reader might ask 'why not do montgomery? you're doing rsa anyway' and answer is not only 'maybe tomorrow, cramer-shoup and not rsa' but also that we do things such as primality testing , and other non-rsa op )
mircea_popescu: the sadness here is that indeed tmsr-rsa is turning into separate item from p itself.
asciilifeform: i hold that it is not meaningful to attempt to separate'em
mircea_popescu: because optimizations. which may piss you off, but it'll be done anyway ; and the process MUCHLY reminds me of how bitcoin mining degraded irl.
asciilifeform: and that an rsa that is not ptronic is not worth using
mircea_popescu: which is a serious point of alarm in my head at this juncture.
asciilifeform: if idjits want to optimize in a way that results in nonfittinginhead, they may as well install winblowz
asciilifeform: and use usg's rsa.
asciilifeform: because there is demonstrably no difference.
mircea_popescu: it's a complicated problem./
asciilifeform: dunno what is complicated about this
asciilifeform: if we gotta compute on fpga, to do rsa sanely -- then fpga it is. 8192-bit regs.
mircea_popescu: the point re why the fuck does everything have to degrate stupidly is what's complicated about this.
mircea_popescu: degrade*
asciilifeform: it degrades because folx let it.
asciilifeform: when you stop letting -- it stops.
asciilifeform: even if cost is 1e6 litres of blood.
mircea_popescu: "badly built house walls fall because people let them ; and when the "stop" letting them by starting propping them up, they stop falling"
asciilifeform: not by propping
asciilifeform: by shooting architects.
mircea_popescu: lol
asciilifeform: propping is how you get walls that dun stay up 5sec when unpropped.
mircea_popescu: i dunno how many people you will have to shoot to keep them from taking your general-purpose p-based rsa and writing a narrower, "works for rsa only" faster program.
asciilifeform: like kochian rsa.
mircea_popescu: neither do you. it's unbound.
asciilifeform: you solve this by making the sane solution, actually usable.
mircea_popescu: your sane solution won't be the fastest.
mircea_popescu: that's always the trade-off, clarity for specificity.
asciilifeform: it's every bit the fastest when sat on proper iron.
mircea_popescu: btw, you have any exposure to the racing cars social millieu ?
asciilifeform: not directly
mircea_popescu: the sort of culture of the 70s/80s of which "need for speed" franchise is a sad bastardization in the ustardian hot topic sense ?
asciilifeform: the folx who took stock cars, and tore out seats, floor, etc ?
mircea_popescu: ok, quick summary : tech pre-injectors was carburators. engines "optimized for racing" got slowly more complex over time. then injection became feasible, and they simplified. now they've recomplexified again.
mircea_popescu: this is a cycle
asciilifeform: it is indeed
mircea_popescu: asciilifeform engine work the interesting part, but sure.
asciilifeform: and answer is that obviously idjits will take ANYTHING you make, sane rsa, sane kalash, whatever, and Bolt Shit To The Side
mircea_popescu: but the process is interestring, they kept adding shit to the old engine to "make it better". which it did, at the cost of becoming unmaintainable.
mircea_popescu: so much so that ONLY DRIVER could fix own car.
asciilifeform: and result, whatever else it may be, is not sane. in that it no longer ~demonstrably~ behaves as specified.
asciilifeform: it is NOT RSA
asciilifeform: it is usg.rsa.
mircea_popescu: notwithstanding EVERYONE there had the practical, earn equivalent of 5 phds in mech eng.
asciilifeform: this is the typical complexitycollapse, happened to, e.g., ibm pc
mircea_popescu: then injection came about, and they scrapped the old designs
mircea_popescu: BUT!!! restarted the complexification process.
asciilifeform: and just about everywhere where folx did not actively push back.
asciilifeform: understand, you gotta ACTIVELY push back
asciilifeform: shoot people for adding complexity. regardless. of. why.
mircea_popescu: sounds a lot like "your house is fine mr p, for as long as you hold on to this here bearing beam"
asciilifeform: it's a pollutant.
mircea_popescu: ok, where does it come from ?
asciilifeform: comes from young cocks who want to 'make their mark', most typically
asciilifeform: and did not get properly hammered down
mircea_popescu: does it ?
mircea_popescu: take the inconvenientmost example, of bitcoin mining.
mircea_popescu: technically you're right -- the change fgrom satoshi's prototype mining to today's item comes exactly from "young cocks" trying to get laid.
asciilifeform: it also comes from 'reasonable' people who 'oh hey i can make rsa 1.5x faster if i use weird bases, so what if my code is now 20kline instead of 2k'
mircea_popescu: nevertheless...
mircea_popescu: well it IS 1.5x faster.
asciilifeform: except that : it is no longer the SAME IT
asciilifeform: not demonstrably.
mircea_popescu: point being, until and unless the process is thoroughly and well understood, we'll keep being blindsided by "mining is a bug" bugs.
mircea_popescu: i know i was. ie, it was not directly evident to me that mining as originally designed has this weakness.
asciilifeform: the process is 'must fit in head'. for so long as item fits in head, it is demonstrably solving the stated problem ( which, unsurprisingly, must also fit in head as a statement )
mircea_popescu: asciilifeform so how do you redefine "winning the race" ? have the drivers recite the engine parts afterwards, disqualify all errors ?
asciilifeform: mircea_popescu: the race is a fuzzy thing to begin with, if the cars can be arbitrarily altered
asciilifeform: ( where do they draw the line ? why not rocket engine ? )
mircea_popescu: not really, very "intuitively" obvious.
mircea_popescu: monkey ahead!
asciilifeform: ahahahahalol
mircea_popescu: ayup.
mircea_popescu: do you know what childhood ad-hoc rulemaking is ?
asciilifeform: 2+ param optimization is a punishment, not entertainment
mircea_popescu: usually takes the form of !Whine that's not fair!
asciilifeform: wtf is it, a car design + racing contest
asciilifeform: why not also singing.
mircea_popescu: and then a rule is added to the set.
asciilifeform: make'em sing
mircea_popescu: actually, it's also DRESSING
asciilifeform: !#s chess boxing
a111: 6 results for "chess boxing", http://btcbase.org/log-search?q=chess%20boxing
mircea_popescu: it is after all sexual competition. gotta be fast, cool and sharp!
mircea_popescu: (ftr, what teh lordship usually catcalls as your "Goalpost sliding" is really your most carnal aspect. you sound JUST like a woman when you do it.)
asciilifeform: specifying detail != sliding
asciilifeform: though may seem that way to fuzzy thinkers
mircea_popescu: well now that all depends.
asciilifeform: i'd like it not to be lost upstack, so will restate ftr : a 'optimized' rsa that no longer fits in head and is no longer demonstrably-correct , ( and worse yet, no longer operates branch-free ) is NOT RSA and is simply a turd being fraudulently passed off as the genuine article
asciilifeform: though it may in majority of observed cases produce 'correct answer' to the naked eye
asciilifeform: the essential point is that the two are NOT SAME mechanisms
mircea_popescu: how do you judge what fits in another's head ?
asciilifeform: i can state with confidence that kochiana fits in NO head
asciilifeform: nor ever will, or could
asciilifeform: generally this is not an actual problem, 'but what of different heads'
asciilifeform: a proper fits-in-head item fits in the literate man's head.
asciilifeform: a tub of liquishit -- fits in none.
mircea_popescu: so you will have a gold-iridium head stored in paris ?
asciilifeform: no such thing is contemplated
mircea_popescu: so then if joe claims the "Streamlined" rsa fits in his head, what do you do ?
asciilifeform: if he ain't in l1, ignore, for starters.
mircea_popescu: and if he is ?
asciilifeform: ask for proof of correctness.
asciilifeform: which incidentally i am ready and willing to produce for every single piece of ffa to date.
mircea_popescu: and he produces a 12 page item.
mircea_popescu: which fits in SOME heads, liek galois' in 1800s or the fermat thing recently.
mircea_popescu: and speaking of fits, https://68.media.tumblr.com/037ffcaa5e3e7d3a5cdf07ba07d0628e/tumblr_nvmn0aRVcF1urdio6o1_1280.jpg
asciilifeform: this is actually the situation with, e.g., fft mult
asciilifeform: which is why we ain't using it.
asciilifeform: arguably the jury's still out on what constitutes 'every literate man's head' capacity
asciilifeform: but my aim is to write an rsa such that, yes, no one can be considered numerate if it does not fit in his head.
mircea_popescu: well, so as you see. complicated problem.
asciilifeform: nuffin in there is any moar weighty than long division.
asciilifeform: which until recently was hammered into every kid
asciilifeform: incidentally this is why i oppose ellipticcurveism
asciilifeform: it does not fit in my head, and i am not convinced that the folx who claim that it fits into theirs, ain't lying
asciilifeform: and moreover i can never be convinced that they ain't lying TO ME
asciilifeform: ( unless and until i were to hammer it into MY head such that it wholly fits )
mircea_popescu: yeah well.
asciilifeform: incidentally in case it weren't obvious, much bloatier rsatrons than the one contemplated in ffa, fit in asciilifeform's head -- e.g. montgomery mult, barrett, various war crimes in that vein
asciilifeform: but i specifically refuse'em because NOT ORTHOGONAL, they don't belong as part of a general-purpose numbertheoretical minimal 'crypto lego set'.

apeloyee: would O(N^2) modular multiplication be too slow?
asciilifeform: apeloyee: anything that beats multiply-then-divide is an improvement, so long as it meets the basic demands ( constant time, constant space, NO branches that depend on input bits, no use of approximations, no massively heavy - 100 loc is a good approx max - code )
asciilifeform: i.e. 0 * 0 mod 0 must result in the execution of exactly the same sequence of cpu cycles, as maxwidthint * maxwidthint mod maxwidthint .
asciilifeform: likewise it also demands that there be NO table lookups
asciilifeform: and no precomputations.
asciilifeform: and no special requirements for operands ( e.g. montgomery or barrett reduction are out. )
asciilifeform: this means that yes it has to work on , e.g., even moduli. or moduli that are substantially larger, or smaller, than either or both of the multiplicands.

trinque: divide by zero joke; I'll show myself out
asciilifeform: lol
asciilifeform: trinque: currently my angle is, to try and make constantspacetime recursive divide&conquer division
asciilifeform: ( instead of the constantspacetimeized knuth division currently in there )
asciilifeform: probably the only actual optimization possible.
apeloyee: what woud be wrong with barrett reduction if you calculate a sufficiently precise reciprocal of modulus N,i.e. (maxint+1)^2/N?
apeloyee: ((maxint+1)^2)/N
asciilifeform: several things.
asciilifeform: apeloyee: for instance, how do you propose to carry out the corrector/verifier without using conditionals ?
asciilifeform: understand, the program may NOT include 'if' or any equivalent.
apeloyee: same way as with divisions.
asciilifeform: knuth division 'restorer' fires either once or not at all
asciilifeform: so it's one mux
apeloyee: yes.
asciilifeform: so how many mux ops would you give for barrett ?
asciilifeform: and prove that it works.
asciilifeform: other thing, apeloyee , is that if ffa does NOT operate on mixed bitnesses. i.e. if your operands are B bits, and you introduced an intermediate of some kind that is 2B bitness, now ALL of your computations with that must be 2B wide (incl. comparisons, nullity checks.)
asciilifeform: this is why it was so tricky to implement karatsuba.
asciilifeform: no ffa basic op will accept operands of unequal bitnesses.
asciilifeform: this is intentional and isn't going to change.
asciilifeform: !!up apeloyee
deedbot: apeloyee voiced for 30 minutes.
asciilifeform: now this isn't even all. how the fuck do you intend to calculate the reciprocal WITHOUT DOING THE SAME DIVISION I'M DOING NOW
asciilifeform: except in 2x the bitness.
asciilifeform: ( which costs 4x as much. and then all the garbage that follows .)
apeloyee: reciprocal can be calculated with newton's method
asciilifeform: is it not getting through that once you introduce a 2B-bit item, you are working in ffa of 2B bitness ?
asciilifeform: the only reason we are able to avoid this in karatsubamulter, is that the 2B is ~never~ treated as one number except on output, it is dealt with in parts
apeloyee: can't extract a reduced-length number?
asciilifeform: if you made the double-wide reciprocal ( i will leave aside the question of how to do this in provable constant time and provable correctness ) you're stuck using that width.
asciilifeform: for the rest of the barrett algo.
asciilifeform: and incidentally barrett , as iirc i mentioned in yesterday's thread, requires that a*b < n^2.
asciilifeform: this is not compatible with my demand of a fully general modular mult op.
asciilifeform: so this really makes the question of whether barrett could, in principle, be made in constant spacetime, academic.
asciilifeform: ffa modular mult MUST produce correct answer for ALL possible inputs a,b,n.
asciilifeform: ( n will not be 0, but aside from this all possible bitstrings are legal. )
asciilifeform: and none may result in any deviation from fixed spacetime ( so no 'use barrett if we can, use montgomery if we can...' etc. NO IFs. )
apeloyee: standard barrett requires a*b<n^2, yes. hence I specified the double-precision reciprocal.
apeloyee: (i'm not talking about floating point, if that's not obvious)
asciilifeform: no i get it
asciilifeform: apeloyee: if you want to write out the full algo, i'll read
asciilifeform: ( put in wotpaste.cascadianhacker.com or elsewhere )
apeloyee: does "full" include newton's algo with correctness proof?
asciilifeform: ideallly. i don't have a fixedtime reciprocal finder.
asciilifeform: and it doesn't afaik exist anywhere to crib.
asciilifeform: currently it seems to me that the reciprocal step ~alone~ will cost more than my knuthdivision residue finder in its entirety.
asciilifeform: this is why barrett is only used in the field when the modulus stays constant.

mircea_popescu: but on the significance front i asked because the principal preoccupation of the russian tsar afrter the french went stupid was to rescue as much of the old world industry stack as possible, which is how jhe ended up with swiss, austrian, french etc manufacturers.
mircea_popescu: that "trademark" is now owned by unilever, as you might've guessed, and it's used to sell items in qatar, as you might've also guessed. the point being that the poor rich arabs are trying to salvage whatever's left of the tsar's pile of salvaged material, today.

asciilifeform: i thought those were late 19th c tech tho
mircea_popescu: entirely orthogonal tech stacks ; and wouldn't you know it that the simple man's reaction to perceptible orthogonality is to pick one and pretend the rest dun exist.
mircea_popescu: asciilifeform define those ?
asciilifeform: the eggs
mircea_popescu: absolutely not.
mircea_popescu: before europe went stupid, and blacklivesmatter all over itself, there was a major concern with making mechanical life.
asciilifeform: made in 1880s, neh
mircea_popescu: hence all the clock towers with figurines, and about 50% of german lands gdp.
mircea_popescu: starting in 1720s!
mircea_popescu: it's a longer running item than computing!
mircea_popescu: and btw, it DID discover computing! hence mechanical calculators.
mircea_popescu: it is also WHY laplace hjappened.
asciilifeform: i recall the automata, von kempelen et al
mircea_popescu: dood could have been a general discussing importantly female transsexuals in the french expeditionary force
mircea_popescu: but the preoccupations of the culture at the time were such that INSTEAD he "of his own" "preferred" to solve some important geometry problemsa
mircea_popescu: so the austrian orfevres could make better movements for their puppets.
asciilifeform: incidentally afaik von kempelen's mechanical voicebox was never replicated even to this day
asciilifeform: ( we had the thread, possibly )
mircea_popescu: so : the faberge egg, the original, was made in 1885 ; but it was the continuation and in a sense the crowing of a current of thought (ie, culture) and proper civilisation that reached back over a centry.
asciilifeform: i can picture it. and specifically what mircea_popescu meant, re 'craftsmanship' tech as opposed to industrial/scalables
mircea_popescu: yes. different concerns entirely.
mircea_popescu: but the point remains that the high performance lathe was invented FOR THIS not for that!
mircea_popescu: and laplace existed BECAUSE OF THIS not because "i fucking love science" and "you like nerds, fuck one" ie "we want to get more science".
mircea_popescu: and broadly speaking -- that without THIS neither laplace nor the lathe are happening, period and full stop.
asciilifeform: lathe driven moar by musketry than by fine art tho
mircea_popescu: more importantly -- that the chinese DID takle over "industry", as well they should ; but that survival and prosperity depends on THIS. let them have THAT industry, it's actually a great fit for them.
mircea_popescu: asciilifeform there's two kinds of people -- and only one of them comes back from the war to complain about the boots.
mircea_popescu: guess which is which.
asciilifeform: did we ever do the chronometer thing ? a bit like that there egg, likewise craftsman 'unindustrial' product, and made the british navy briefly +ev
mircea_popescu: (and to round off the above : consider that the first metallic aluminum was shaped into a box and offered to the same person as the ironclad drawings were offered. whyssat ? cuz that's how all science flew back when people could control it.)
mircea_popescu: asciilifeform yeswedid.
asciilifeform: mircea_popescu: funnily enough there is a monument to this aluminum right here . washington obelisk has a top, 'priceless' pyramid of al

mircea_popescu: "your higheness, have your favourite slave fuck herself in the ass with it!"
mircea_popescu would be genuinely curious if this could be done. on one hand trained girl can do wonders with ass, on other hand that thing is fragile as all fuck...
asciilifeform: could be done
asciilifeform: and not only could be, but could be attached to the end of a red hot poker , and subject would feel no heat
asciilifeform half-expected mircea_popescu to say that he already had owned aerogel dildo.
mircea_popescu: lol.
mircea_popescu: no, gotta leave something for the industrious to gift.

mircea_popescu: aha.

mircea_popescu: well you print things
asciilifeform: iirc early 1990s ( pre-pantsuitization ) sci-am mag.
mircea_popescu: :p
asciilifeform: naah loong ago
asciilifeform: aerogel'd make a spiffy pedestal for sram pc...
asciilifeform has a coffin notebook little list of items that nobody knows how to produce industrially, and so never expects to touch with own hands
asciilifeform: it's really half the attraction of having own decent lab setup
asciilifeform: some folx make holographs today, in their cellars, it is i suspect the same attraction. rather like colour film in 1930s
asciilifeform: 'want it? gotta do it yerself, corner store won't even dream of it'
asciilifeform: ( personal comp in 1970s. etc )
asciilifeform: there is imho a marked difference tho b/w 'nobody mass produces this' and 'nobody knows how'
asciilifeform: ( possible example of the former -- http://btcbase.org/log/2015-01-18#982523 ; of the latter -- aerogels )☝︎

asciilifeform: was thinking of the 'omfg it floats in mid air' rather than thermal aspect, there.
mircea_popescu: now, good insulation DOES model the flow of heat, ie the hotter outer part will cool more before it touches your sram, so not entirely useless.

mircea_popescu: i can't say that i know. what complexity is our current item ?
mircea_popescu: n^3 ?
asciilifeform: as of my last reckoning O(n^3 log n)
mircea_popescu: heavy.
asciilifeform: but i still gotta massage the divider
asciilifeform: right now it is 'egyptian' (knuthian) and goes bitwise
asciilifeform: it oughta go wordwise.
mircea_popescu: aha.
asciilifeform: other observation , gleaned from mircea_popescu and then from knuth -- can modularly ~add~ inside karatsubatron
asciilifeform: and this works out
asciilifeform: ( precisely how to do this, i have not yet determined )
mircea_popescu: oh btw, should prolly formalize the function/mechanism thing from yest a bit. so, a function (in the correct, math understanding, a "procedure" in cs lingo is no different, which is why lisp hasn't "procedures") denotes correct results, but does not connote any particular method of obtaining them. this is no good for us, in many military applications, where we must actually specify not merely WHAT is being sought, but also HO
mircea_popescu: W, precisely, it is to be obtained. this is why the concept of "function" as heretofore used is not useful in republican computing, and we must introduce a new item.
mircea_popescu: this new item is to my eyes fundamental pillar of "fit in head", because a thoroughly well understood mechanism can then be relegated to background and built upon.
asciilifeform: what's wrong with 'circuit' ?
asciilifeform: that's what it resolves to.
asciilifeform: show the gates.
mircea_popescu: pure historical accident. you'd rather call it circuit ?
mircea_popescu: there's some common language overload that seems to make "mechanism" preferable, but it's slight and who cares.
asciilifeform: it reflects the reality of what a 'constantspacetime program' really is.
mircea_popescu: this is a solid point.
asciilifeform: and why almost the entirety of the ~useful~ reading material asciilifeform collected, was from iron makers
asciilifeform: outside of perhaps ballooning, continuously-variably-voluminous entities are rare in engineering
asciilifeform: maker of cpu will almost unavoidably take an interest in 'ffa-style' arithmetizing.
mircea_popescu: well, it's the core of the combustion engine, innit ? continuously-variably-voluminous.
asciilifeform: not whole engine, lol
mircea_popescu: :p
mircea_popescu: asciilifeform waitasecond!
mircea_popescu: wtf you mean wordwise ?!
asciilifeform: the way the comba multer works
asciilifeform: notice that it doesn't walk the bits
asciilifeform: ( the egyptian multer, now gone -- did walk the bits, and was directly analogous to the knuthian divider )
mircea_popescu: this is the stupidest shit i ever heard. gimme two numbers.
asciilifeform: 3, 5
mircea_popescu: 8 digit.
asciilifeform: 349087340, 753059056
asciilifeform: ( shave'em if you like )
asciilifeform: believe or not there are several known subquadratic division algos
asciilifeform: one by jebelean, 'Exact Division with Karatsuba Complexity' , possibly ffaizable.
asciilifeform: ( if it can be turned into div with remainder... )
mircea_popescu: Here's how we divide 349087340 to 3059056 :
mircea_popescu: 1. we notice that 349087340 being 1 0100 1100 1110 1010 0110 0110 1100 is 29 bits long. we further notice that 3059056 being 10 1110 1010 1101 0111 0000 is 22 bits long.
mircea_popescu: 2. we select the first 22 bits of the dividend, to wit 1 0100 1100 1110 1010 0110 0 and we compare the divisor to it. as the divisor is larger, we add one further bit, obtaining 1 0100 1100 1110 1010 0110 01.
mircea_popescu: 3. we substract the divisor from this fragment of the divident, obtaning 1 0100 1100 1110 1010 0110 01 - 10 1110 1010 1101 0111 0000 = 10 0100 1000 1101 0010 1001 (aka 2395433).
mircea_popescu: we continue comparing the divisor, adding bits from the divident's tail and substracting the divident until we run out of digits, at which time we have the remainder. every time we substract we mark down an 1, every time we add digits from the divident's tail we mark down a 0.
mircea_popescu: wtf "wrodwise" ? the only way to do division is divisor-bitsize
asciilifeform: mircea_popescu: you just described our existing divtron aha
mircea_popescu: so then what is bitwise in it ?!
asciilifeform: the fact that it advances a bit at a time ?
asciilifeform: i.e. shifts by 1
mircea_popescu: oh i see what you mean.
asciilifeform: http://wotpaste.cascadianhacker.com/pastes/oVOak/?raw=true << yest's paste for ref
asciilifeform: for i in 1 .. Dividend'Length * Bitness loop ...
mircea_popescu: and since i've this piled in here : to ~multiply~ 349087340 by 3059056 : you create a list 22 items long, that is 29 + 22 bits wide, and you proceed writing down 1 0100 1100 1110 1010 0110 0110 1100 in it bit-shifted 22 times, nulled on occasion. then you add these terms. right ?
asciilifeform: that was how my first ffa multer worked
asciilifeform: 'egyptian algo'
asciilifeform: it was about 100x slower than comba ( current basecase ) and ~150x slower than karatsuba+comba ( currently what we use )
mircea_popescu: aha!
mircea_popescu: is that 100 or 150 related to a particular bitsize ? 8096 ?
asciilifeform: not really
asciilifeform: it flows from the fact that we walked 1 bit, rather than ( on my box ) 64 at a time
asciilifeform: for every single subop
mircea_popescu: myeah.
mircea_popescu: gotta workwalk.
mircea_popescu: word*walk
asciilifeform: i threw out egyptian multer very reluctantly, it was so short an' sweet
mircea_popescu: it is.
asciilifeform: it's what yer cpu still does internally.
asciilifeform: ( simplest possible mul )
mircea_popescu: very evidently what it does. at least to the sort of people who learned how to write in longhand and do square roots by hand
asciilifeform: it's how i learned'em
mircea_popescu can still do this.
asciilifeform: the magic of arithmetizing by hand.
mircea_popescu: da fuck is wrong with people these days, i do not know, but i do recall as early teens, 12 yo or so, there was this very exciting moment in school when they imported AN AMERICAN!!! to do some english classes. this was you know, wild wild stuff at the time.
mircea_popescu: and he proceeded to blockprint. which was about as shocking as if he had taken off pants in class.
mircea_popescu: after which we had kid council, decided guy is not really a teacher.
mircea_popescu: because srslty now who the fuck block prints if they ever went to school..
asciilifeform: ( it is worth remembering that ffa is not built to be a museum piece, 'shortest physically possible rsa', but grudgingly made concessions liek abandoning egyptian mul -- so long as result is still fixedspacetime -- , so that it can actually be fired in anger . )
mircea_popescu: (it didn't help that it was in the torah of the time, as per saint habarnam gospels, "only blockprinted")
asciilifeform: believe or not, asciilifeform never learned proper latin penmanship.
asciilifeform: it was ~eliminated in the schools shortly before he landed in usa .

mircea_popescu: you can not mark them for the latter, i guess, but the point must be made that no, NOTHING EVER STOPS.

mircea_popescu: and here's the engineer's sliderule for logs tee hee.

mircea_popescu: also lulzy, in simiular vein, though i wouldn't for a moment call it "capitalist hell". it is pure and simple collapse among the symbols, as typified in teh elevator scene.
mircea_popescu: ie, there's nothing capitalist about it whatsoever ; capitalism does order the disordered symbols in similar manner as longhand does, as an act of civilisation and a point of manifest superiority pointedly absent from the work (or generally ustardian mentality today)

a111: Logged on 2017-09-13 17:31 trinque: divide by zero joke; I'll show myself out
mircea_popescu: fwiw, in my universe mod 0 is defined, and has the value 0.
asciilifeform: this carries lulz potential
mircea_popescu: this is because of set theoretic considerations whereby increases in the mod parameter increase the pile of possible results, eg mod 2 is 0 or 1
mircea_popescu: the other school of course says mod 0 is an indifferent op, ie 18 mod 0 = 18
mircea_popescu: this is nonsense, but i won't delve into why.
mircea_popescu: of course the computronist would think mod 0 is "an op that dun terminate". but in any case, the "divide by x" approach to calculating a mod is just shorthand, not fundamental. mod is defined in terms of substraction (take x and y, substract y from x until remainder sub y), has nothing to do with multiplication side of the number ring.
mircea_popescu: and so in these terms, the question becomes "if you substract nothing from something an infinite number of times, what're you left with ?"
mircea_popescu: and you're left with nothing.
asciilifeform: this is when i point out that div0 gives maxint in ffa ( at least naked ffa, without checking first )
