We all do weird things when dealing with grief, but I was tickled by the fact that Mara’s bizarre pie-eating method still managed to leave the crust mostly intact."

asciilifeform: this with 0 asm
asciilifeform: and 0 parallelism
mircea_popescu: this is 2sec per exp mult is it ?
asciilifeform: correct.
asciilifeform: 8192bits in particular.
mircea_popescu: what's a 4kb keygen, gotta look for the primes, say a few hundred emults ?
asciilifeform: depends whether you get lucky, lol
mircea_popescu: yes, but i mean as the middle of distribution
asciilifeform goes to the torture room answer this q empirically
mircea_popescu: it's conceivable 2s is actually good enough (tm)
asciilifeform: sooo a 4096b rsa key takes about a dozen modexp's, on avg, on gpg 1.4.10
mircea_popescu: splendid.
asciilifeform: a 8192b key, not yet known, because gotta patch it to even allow one
mod6: <+asciilifeform> and 0 parallelism << cool!
mircea_popescu: i don't want 8kb keys
asciilifeform: i'm writing a proggy meant to be wholly devoid of 640isenoughforeverybody-isms
mircea_popescu: this is sane in any other case but key size.
mircea_popescu: do teh math, if 8kb rsa key is preferable to 4kb rsa key, there's fundamental problems with rsa that make it useless anyway.
mircea_popescu: and this nonsense of offering faux meaningless choice a la kochpgp is unwelcome and shouldn't be perpetuated. keys are 4kb and forget about it.
mircea_popescu: and not even 4096 bits, there's a whole speccing discussion re this in teh logs
asciilifeform: i ain't putting idiot magic numbers in. anywhere.
asciilifeform: not happening.
mircea_popescu: asciilifeform well there is that. nor should you. butwhat happens to 8kb keys is of ~0 interest nevertheless.
asciilifeform: at any rate a p proggy starts with the register bitness
asciilifeform: incidentally, mircea_popescu's argument could just as readily be made re 4096 vs 2048 etc
asciilifeform: each theoretically 'needs multiple planets' to break via traditional methods
mircea_popescu: not so. why i said do the math : cracking 4kb key the hard way exceeds the universe. this is a categorical argument, substantially different from "i could compute 2 bit key by enumeration on napkin"
mircea_popescu: asciilifeform no. one needs multiple planets, the other exceeds matter.
asciilifeform: i can think of other considerations, as in the thread with the exponents
mircea_popescu: where the fuck is that tmsr-standard-rsa-key discussion
asciilifeform: on mircea_popescu's www iirc
mircea_popescu: o it was ? i was murdering the logsearch
asciilifeform: lol kochgpg ends up computing garbage if the 4096 cap is removed
mircea_popescu: guaranteed bug you found.
asciilifeform: betcha nobody ever tested its bignumtron with longer ints..
asciilifeform: 'doctor, it hurts...'
mircea_popescu: ie, koch bignum dun actulaly work.
asciilifeform: fwiw mine -- worx
asciilifeform: kB, mB, dunmatter.
a111: Logged on 2016-08-03 04:34 mircea_popescu: actually to formalize that : a 4096 bits key means a p that is 257 to 259 bytes long ; and a q that is 258 to 260 bytes long. end of fucking story.
asciilifeform: aactually bug in my gpg torturetron, so :
mircea_popescu: ^ very specific what a key is. not "interchangeable p and q"
asciilifeform reruns the test
mircea_popescu: (yes this yields keys slightly longer than 4kb. good.)
asciilifeform: ok actual answer is about 100.
mircea_popescu: asciilifeform what i had also.
asciilifeform: ( modexps per 4096 mod )
mircea_popescu: it is entirely acceptable for proper keygen to take up to a few hours. 200 seconds is actually exceedingly fast.
asciilifeform: will be moar if greater millerrabin margin is used , also
mircea_popescu: asciilifeform that's another thing i would like : a graph of the relation of the m-r failure rate to the a) entropy quality and b) margin.
mircea_popescu: ie, is the relative impact cuadratic or subquadratic ?
asciilifeform: mircea_popescu: this'd be an interesting adjunct to the dh tests even.
mircea_popescu: which incidentally brings us to a very workable and very useful tmsr definition of entropy quality : take a FG string. flip a number of consecutive bits to 1. the result is your entropy quality, such as 100/1mb if you flipped 100 bits.
mircea_popescu: asciilifeform yes.
mircea_popescu: could also be derived mathematically, but so far've not managed to.
shinohai: https://github.com/btc1/bitcoin/issues/65 <<< This Summer, even the testnet forks.
asciilifeform: 'mathematics of computation' vol. 61, no. 203, july 1993, pp. 177-194 ( https://www.math.dartmouth.edu//~carlp/PDF/paper88.pdf << yes it's a scan, ain't got another ) appears to give the desired bounds for miller-rabin.
mircea_popescu: now i gotta read a pdf
asciilifeform keeps dedicated iron around for the purpose
mod6: how come they don't publish these things in ascii like normal people?
mircea_popescu: possibly maffds
asciilifeform: mod6: if ~you~ type it up, it'll be ascii...
mod6: ah right. still sux tho.
mod6: asciilifeform: lol indeed.
shinohai curled it and piped through pdf2text, seems readable ....
asciilifeform: mircea_popescu: for completeness, exp with 4096 operands takes ~0.3s. per. on current ffa.
mircea_popescu: not terrible even
mircea_popescu: asciilifeform i had actually read this text, though pretty sure not in this paper. but i recall the 100,10 bounds etc
mircea_popescu: this is still less than my graph.
mircea_popescu: they have the p k, 1 < 4 ** (2 - sqrt(k))* k**2 , which is useful, but i also want the p k, m
asciilifeform: prolly hadamard's thing re prime distribution is the closest we're likely to get to an exact answer
mircea_popescu: i would very much like an exact bound, rather than an exact solution
asciilifeform: which is frustrating because you can't resort to 'empirical test' here , because circular, there EXISTS NO 'gold rng'
asciilifeform: hey wouldn'tit be spiffy if we had an exact answer re prime distribution, lol
mircea_popescu: what do you mean there exists no gold rng ?
asciilifeform: recall the dh thread
mircea_popescu: asciilifeform by my lights, exact answer re prime distribution prerequisite to trivial factorization of rsa.
mircea_popescu: asciilifeform yes, i recall.
asciilifeform: there is no 'gold standard' to which i could compare fg, etc
mircea_popescu: there is no gold standard to which you could compare the gold standard ?
asciilifeform: aha!11lolyes
mircea_popescu: does this make you suffer greatly ?
asciilifeform: not usually.
asciilifeform: but sometimes it is inconvenient.
mircea_popescu: aite, me either.
asciilifeform: now for another little mindfuck,
asciilifeform: same figure sans karatsuba : 3.7s.
asciilifeform: ( alert reader will ask, what did i change ? answer : 1) comba 2) gcc -O2 (this keeps all bounds checks and dun do anything aggressive, just peepholes) )
mod6: asciilifeform: huh
asciilifeform: mod6: i was running with -g -O0 previously, lol
mod6: oh -g
asciilifeform: aha, it also
mod6: im retarded, what is 'comba' ?

mod6: asciilifeform: thx, will read
mircea_popescu: asciilifeform this sounds like the ugliest of hacks.
asciilifeform: mircea_popescu: it ain't tho.
mircea_popescu: why does ada do that, anyway ?
asciilifeform: because not doing it would lead to increased ugly.
asciilifeform: though i also found it at first difficult to understand why.
mircea_popescu: i realyl don't like this "and now we magic-variable the numbers". it's one step up from magic constant
asciilifeform: slices are not arrays in their own right, they are offsets into another array
asciilifeform: and ergo retain the original's indexing.
asciilifeform: so you can get it back from a slice
mircea_popescu: wouldn't it actually be proper to copy the slice into its own array ?
asciilifeform: that ain't called a sloce
asciilifeform: that's a copy, we do this also sometimes.
mircea_popescu: wouldn't it be actually proper to copy the slice into its own array and to maintain a pairing of slices and new arrays ; rather trhan do index magics on the mult code ?
asciilifeform: nope. blows the cache.
asciilifeform: and bloats the algo.
asciilifeform: worst of all worlds.
mircea_popescu: i didn't say practical, i was just going with proper
asciilifeform: seekrit : in the 'most fascist' restriction mode, ada... copies slices
asciilifeform: ( behind the curtain )
mod6: ah.
asciilifeform: (no_implicit_loops pragma iirc)
mod6: i've read, so far seems ok -- i've got to wrap my mind around the second ("high loop") as I did before.
mod6: gotta take it the whiteboard a bit later perhaps.
asciilifeform: upstack, array slices ( which commonlisp also has ) are important to being rid of having to use c-style pointers
asciilifeform: in much the same way as 'in' parameters (in ada procedures)
mircea_popescu: i am sitting here wondering if this is "getting rid" as in, rid or rid as in, hid.
asciilifeform: in that they are replaced with a far more constrained item
asciilifeform: about which you can prove particulars.
mircea_popescu: what particular can i prove re the relation between an array slice and the index fixer variable ?
mircea_popescu: ~same as the relation between pointer and its content, "better hope programmer didn't fuck up ; and also it usually blows up if he did so there's that"
asciilifeform: they get checked against the bounds
asciilifeform: every. time.
mircea_popescu: ah so no overflow
mircea_popescu: but can i overflow THE SLICE ?
mircea_popescu: wedll that's something.
asciilifeform: slice has own bounds, the correct ones.
asciilifeform: ada is a thing for a reason, i found. hence this entire thread.
mod6: so recently, i've done some multi-d array programming in ada..
asciilifeform: every time, to date, when i bashed head against wall and went 'WAI DOES IT DOOO THAT!1!!1' i ended up repenting
asciilifeform: 'oooh hey turns out, Right Thing'
mircea_popescu: that's encouraging...
asciilifeform: quite possibly i'dve given up long ago if not for this repeated experience
mod6: all i can say thus far is; stuff seems to be strict. my code may compile, but indeed blows up at runtime.
asciilifeform: every single time it was 'guess wat, this is How It Works in the adult hut. for reasons that Make Sense'...
asciilifeform: mod6: note that 'blow up' still dun mean 'segfault'
mod6: index out of bounds.
mircea_popescu: he means it catches it itself
mod6: or whatever it was. no did not seem to be a segfault.
mod6: im just dumb. it seemed to be smarter than i am.
mod6: at least, for nw.
asciilifeform: mod6: you won't physically ever see a segfault in ada proggy built with default 'fascism' level
asciilifeform: most you'll get is a stop.
mod6: that's what would be ideal
mod6: :]
asciilifeform: in some critical applications (airplane, rsatron) this is still unacceptable and hence spark
mod6: now if i could just my head out of my ass....

asciilifeform: the asm
mod6: is it doing ~what is expected?
asciilifeform: on -O2 it's surprisingly notbad
asciilifeform: mod6: aha. i wanted to see how the bounds checks are done, and whether gcc4.9 takes any liberties with'em
mod6: good work.
asciilifeform: seems like it works - almost astonishingly - as printed on the box...
asciilifeform: ftr asciilifeform doing this chore does not excuse other folx from same
asciilifeform: my gnat is mine, but what's in yours - only beelzebub knows
asciilifeform: relatedly, after adatronic 'p' is fully nailed down and flying, i'ma bake one in x64 asm.
asciilifeform: in the interest of bootstrapology.
mircea_popescu: not even a bad idea
asciilifeform: ( ffa in asm is - somewhat surprisingly - easier than ada or even c )
asciilifeform: phunphakt -- if you nail down, to a fixed bitness, the N-arity of the arithmetic, you can unroll all of the loops.
asciilifeform: e.g. mircea_popescu's 4096
asciilifeform: pretty lulzy, jmpless rsatron then
asciilifeform: but iirc this came up in old thread.
mircea_popescu: part of the point
asciilifeform: ( i dun know of any compelling practical reason to do this, outside of something like a hand-sewn gossipd packet filter in asm on bare iron, for max horsepower )
mircea_popescu: unrolled loops means fixed time eh.
asciilifeform: constant-arity loops - equally fixed
asciilifeform: but unrolled is moar cacheable.
mircea_popescu: but unrolled loops you can bake in your alfmachine we were discussing last week
mircea_popescu: moreover, if you do fixed as described, you CAN so unroll, if you do or if you don't.
mircea_popescu: otherwise, you CAN NOT.
asciilifeform: in my mind's eye thing would be a 32kBit-arity alu...lol
mircea_popescu: 4kbit first
asciilifeform: same principle
mircea_popescu: yes, but cheaper by a factor
asciilifeform: and if made correctly they oughta plug in for longer arity.
asciilifeform: the way folx used to stitch shifters together.
mircea_popescu: well yes, i imagined the 4kb one also composite.
asciilifeform: upstack, ffa wants to double as a 'how to rsa' 'b00k' , i.e. at every point tradeoff was made for clarity rather than speed.
asciilifeform: we can always get the speed BACK later
asciilifeform: but try and get back lost clarity!!
mircea_popescu: just as should be. first spec code then optimized code
asciilifeform: p ain't a 'code is the spec' crock-o-shit tho. up asciilifeform's sleeve, is an actual spec
a111: Logged on 2017-07-04 15:06 mircea_popescu: http://btcbase.org/log/2017-07-04#1679054 << this is a fine approach. "here's the per spec impl, here's the optimized impl. you can verify they agree wrt results ; and you can trivially verify the former is spec-accurate."
asciilifeform: i don't expect to see many reimplementations, sadly, however, because one of the items of said spec is 'the following ops are in constant spacetime...'
mircea_popescu: which suggests the very important point : bitewise equality over the result space is not sufficient proof of program equivalence.
asciilifeform: probably an ada build and a handrolled asm, per cpu make, is best that can be had.
mircea_popescu: aka "you can not fix a computer by simply rebooting it without any idea what's going on" moonism
asciilifeform: mircea_popescu: aka 'path dependent'
mircea_popescu: asciilifeform incidentally, unrelatedly and idly : an optorsatron might also be built if unrolled.
asciilifeform: or even... mechanical
mircea_popescu: the two aren't that distinct in this application
asciilifeform: ( esp. if you use muller's delay-insensitive logic )
mircea_popescu: but it'd make fine ART, to go back to http://btcbase.org/log/2017-07-07#1680182
a111: Logged on 2017-07-07 18:01 mircea_popescu: if they did that sort of shit, i could almost respect artists.
mircea_popescu: asciilifeform aha
mircea_popescu: it should not take the average artist a year of labour to produce the optorsatron out of cheap lasers and stuff ~free in any collegiate lab, once he's stolen the unrolling and idea from log.
asciilifeform: part of what asciilifeform was even doing re 'p' is answering the q of 'what is the minimal practical rsatron'
asciilifeform: ( lessay you had to put one in a very... tight space. e.g. 'uci' payload... )
asciilifeform: the tightest, in practice, space of all, however, is.. the head
asciilifeform: if you want ( and we do ) an ABSOLUTE, iron grasp.

mod6: i haven't gone all the way through the W_Mul yet, but just unrolling it as said.
mod6: for i in L .. 2*L - 2 loop
