asciilifeform: ( if it isn't obvious from where the error comes : observe the 3 Karatsuba_Term additions. in ordinary K., they walk over the upper half of XYLo ( lower half of result.) but in TopOnly K. we lose XYLo, so that carryolade is lost. )

phf: shinohai: http://p.bvulpes.com/pastes/ZqN4y/?raw=true
shinohai: ty phf
mircea_popescu: phf his point is that if you're going to compare fixtime with something else, better make sure you get a long case in there too.
phf: mircea_popescu: well he either has a constant time algorithm in ffa, in which case if the goal is to compare speed specifically we should be comparing fixtime ffa and fixtime something else. otherwise he has a variable time algorithm running at worst case constant time, in which case the comparison is between base operation speed, which is still going to come out on top
phf: i guess the point of this exercise is to show that iteration sizes further leak timing information
mircea_popescu: you're not having any of this new fangled "constant time ~= fixedtime ie, variable time running at worst case" ?
phf: well, it's conveniently two strategies: closed form solutions and constant iterators. if you don't have a closed form solution, you have to iterate, which you simply do at the upper bound constraint by a data type size. i don't see how theoretically it can be anything else
mircea_popescu: myeah
shinohai: I get 0m1.236s using sbcl (i5)
phf: i suspect that ffa's take on expmod is to iterate over every bigit of the exponent, which will have to perform base operations no matter what the numeric size is, but that's a guess.

mircea_popescu: so then what exactly is the argument about.
asciilifeform: http://btcbase.org/log/2017-10-07#1722415 looked like a 'who needs miller-rabin'
a111: Logged on 2017-10-07 23:50 mircea_popescu: http://btcbase.org/log/2017-10-07#1722405 << this may actually be a better check than any miller-rabin, and at any rate a good complement. gcd with primorial.
mircea_popescu: yeah well.
asciilifeform: ( where first suggested , ftr : http://btcbase.org/log/2017-08-14#1697598 )
a111: Logged on 2017-08-14 17:15 asciilifeform: idea is, for pre-millerrabin litmus, take gcd(candidate, Qw) where Qw is largest primorial that fits in the ffawidth
asciilifeform: worxgreat
mircea_popescu: incidentally, if looking for 4096 bit prime wouldn't the correct approach be to take 4094 bits of rng and glue 1 on either end ?
mircea_popescu: as no 0 led or 0 terminated string will ever pass anyway
asciilifeform: primes >2 are odd, noose at 11
mircea_popescu: aha. get some free bits that way, fwiw.
asciilifeform: ( yes you set the low bit to 1 )
asciilifeform: http://www.loper-os.org/?p=568&cpage=4#comment-18272 << in other strange.
shinohai: Lol asciilifeform got a brony
shinohai: Oh wait, name is "Tina"
asciilifeform: i have deeply nfi
asciilifeform: in other lullies, http://www.loper-os.org/pub/nsawagenhoneypot.jpg << found on washington metro train today
shinohai: TOP KEK "Anonymous access through tor browser"!!!!
shinohai: They even bothered to vanitygen a custom tor addy
asciilifeform: ads on these trains, ftr, not cheap. ( and certainly not 'to allcomers' )
