asciilifeform: http://btcbase.org/log/2017-10-05#1721065 << i oughta expand on this step : first we do r := x - q*m ; then it needs from 0 to 3 further subtractions of m ( we do this muxically . ) ☝︎
asciilifeform: the (unsurprising) surprise is that ^method is wholly absent from the public lit ☟︎
mircea_popescu: on teh contrary
asciilifeform: ( at the cost of n log n )
asciilifeform: mircea_popescu: i did conjecture that you can skip normalization if you widen the register.
asciilifeform: given that currently we have only symmetric (equal-bitness multiplicands) multiplication, which will waste massive cycles
mircea_popescu: asciilifeform both salient points (the multi-try mod ; the divide powers of two by p) were part of a larger discussion where you defended tooth and nail teh impossibility!
asciilifeform: as for gains, i dun know for sure yet, because i gotta manually implement the asymmetric karatsubaization for the above
asciilifeform: he proposed to do the normalization as usual, but with 'secret shift' algo. which , any way you cut it, eats more cycles than knuthian division even.
asciilifeform: mircea_popescu: this is quite different from the apeloyee d00d's suggested method
asciilifeform: in ordinary barretting, x loses its bottom however-many bits, to make the multiplication smaller, depending on the 'bitlength' of x; and then its gets restored with a leftshift . we can't do this, because ffa.
mircea_popescu: sounds like the whole discussion coupla weeks ago actually found its way into actual practice.
asciilifeform: now r is == to the remainder of x/m .
asciilifeform: so now we gotta r := x - q*m , from 1 to 4 times ( this is done via subtract and mux-on-carry , so it always happens 4 times, but when q becomes == to q' the mux stops changing the result ) ☟︎
asciilifeform: if q' is the actual quotient, the inequality q' <= q <= 4q' holds. ( proof left for the reader )
asciilifeform: compute the quotient-guess q, q := (c * x) >> 4096 ☟︎
asciilifeform: note that this is a 4097-bit ( in actual ffa, 8192b ) constant. ☟︎
asciilifeform: compute 'barrettoid' c for the current m : c := 2^4096 / p . this is done via the knuthian longdividotron, once per modexp. ☟︎☟︎
asciilifeform: let, for concreteness, x's are 8192 bits wide ( as they are in the 4096b rsa demo. ) m - in same - is 4096b wide.
asciilifeform: in other noose, asciilifeform derived a simple constant-time variant of barrett. short enough to put in the l0gz:
mircea_popescu: they need help like they need designer bags.
mircea_popescu: i don't think it can be put into words, how much of the whole "poor people need help" the pay-for-your-tits disabused in my mind.
mircea_popescu: there's half a billion of them, and what, one a year manages to find her way to a hundy ?
shinohai: If I made that offer on some South-American camslut site, it wouldn't last a week.
mircea_popescu: an honest man, he is ; actually functional in any proper sense, they aren't.
mircea_popescu: and in other lulz : https://www.stripperweb.com/forum/archive/index.php/t-181800-p-2.html (poor dooglus ended up paying a 4k btc to a bunch of lazy retartds pretending to be strippers, two years after.) ☟︎
mircea_popescu: i don't expect they can fly in this. eagle isn't a swallow.
mircea_popescu: these pair of eagles came to say good morning erry day, nowehre to be seen this morn.
mircea_popescu: the avian biodiversidad is pretty fucking sad looking, i'll tell you that.
shinohai: mircea_popescu should hold kite-flying contest amongst the slaves. Winner is girl who can keep kite aloft for 2+ minutes using only erect nipples.
mircea_popescu: apparently this is now possible.
mircea_popescu: aaand in other "global warming" lulz, costa rica has been beset by an... anti-tropical storm, with temperatures 10 degrees below period averages and winds in the 50kph+ range since yest.
mircea_popescu: aaand in other "after graduation i plan to spend a year in africa doing charity work" news, http://i.4cdn.org/hc/1501923521316.jpg
BingoBoingo: Bouncy's one of those weird qualities.
mircea_popescu: experience is a valuable teacher absent for most experts.
mircea_popescu: and a lot of redditors would be surprised at how bouncy tits are.
mircea_popescu: I THINK REBOUND IMMINENT!
mircea_popescu: a yeah, what happened to her ?
BingoBoingo: Is that Elaine?
mircea_popescu: hy not advertise honestly? Nonprofits are allowed a 3% management fee so VC firms can still afford disgusting salaries and daily crudité delivery. Maybe that decreases the likelihood that endowments and pension funds allocate assets to Silicon Valley, but LPs allocate less than 0.5% of their funds to this subset of private equity anyway. Venture capital is already a tax writeoff." << check out who gets how the whole pile of
mircea_popescu: "Venture capital isn’t an asset class, it’s a system to transfer wealth from state pension funds into the pockets of general partners. Some of the wealth moves into the pockets of kids working on new technology. This part is important, because that technology can have a moonshot chance of improving the world. Someone’s gotta fund moonshots, and it’s not gonna be banks. Venture capital, then, is a charitable service. W
trinque: mircea_popescu: get it out for ya tomorrow with a fresh brain; about to retire for the night
mircea_popescu: nah, likely will unwind the way of ~any other scam
asciilifeform: also great, can't wait to buy ticker to watch the cement poured
mircea_popescu: asciilifeform whatever, "investors displeased with key figures" if you prefer the in-universe formulation
trinque: this urgent, or can wait til tomorrow?
trinque: http://archive.is/IrEBe << "Two black lawmakers in the U.S. Congress" something or other
a111: Logged on 2017-10-05 04:03 mircea_popescu: in other great news, looks like the politruks got together, decided they really only have the office space for one of the two, and axed twitter.
BingoBoingo: I wonder how pissed average USian would be if they learned large chunks of the world gets 6%+ economic growth sustained over decades
mircea_popescu: but i'll lol, which is comparatively the larger part anyway.
mircea_popescu: nor will they ever raise the acumen to confront the plain reality of how they ~should~
BingoBoingo: Hey, walmart is moving to online strategy of "Amazon 3rd party reseller market" but shittier website
mircea_popescu: all the fucktards going around wikipediaing for the past decade won't chase me around so i step on their worthless bodies instead of the pavement, of course.
mircea_popescu: not only for the direct reason, but for the implicit hope that maybe... wikipedia follows suit ?
mircea_popescu: moving towards "advertising agency" in desperation is perhaps the lulziest fiat conceit yet.
mircea_popescu: in other great news, looks like the politruks got together, decided they really only have the office space for one of the two, and axed twitter. ☟︎
mircea_popescu: meanwhile in turning tricks graduate program, http://68.media.tumblr.com/a2bf60987cb1dcd16c5c19e9c95542ef/tumblr_nrgm54GA0c1uwmng9o1_1280.jpg
mircea_popescu: asciilifeform character in true romance. thinks he's black.
asciilifeform: however it would very conspicuously rock , imho, if one of you folx did this, instead of waiting. ☟︎
asciilifeform: it also occurs to asciilifeform that he is doomed to at some point write something like a sane 'tinyscheme' in ada. so that we have a scripting lang and can finally pour the cement into grave of python.
asciilifeform: afaik 100% of the useful functionality, reduces to 'half-written, buggy implementation of' v.
asciilifeform: trinque: to this day i have nfi why portage weighs what it weighs, or what most of the liquishit does
a111: Logged on 2016-04-08 22:17 mircea_popescu: this guy, thinks he's a nigger. got a bad scar and missing eye.
mircea_popescu: kinda why any serious graduate programs in the us should include 6 months assbatical, spent twinking for drexl in baltimore.
mircea_popescu: the high level "fuck you, i own this world and everything in it and you will either adapt or fucking die, bitch" is... not really accessible, mentally, to kids with college degrees.
trinque: evolutionary thing, where various parts of the problem bit them, then they adapted what they had.
asciilifeform: mircea_popescu: it's a fungus. mircea_popescu in particular is fond of reminding asciilifeform that fungi dun have with what to 'try'
mircea_popescu: by the same angular measure, they tried to nearly not be v.
asciilifeform: it's almost funny, thing nearly tried to be 'v' .
trinque: which, gentoo musl overlay is a git repo somewhere. whole thing would have to be repo'd for cuntoo
trinque: primary difference is leaning on the "layman" thing to maintain a tree of patched ebuilds
mod6: This will be quite awesome. "Here lies mod6. emerge trb" it will say.
trinque: why not use an ebuild to build instead of "stator"
trinque clears throat
asciilifeform: trinque: that's what i meant by 'cuntoo'
mod6: yeah, i think emerge a trb would be the ticket, no?
trinque: whole point is to have total control over the OS
trinque: why not just ebuild, there
asciilifeform: and get same result that you currently need buildroot for on heathenlinux
mod6: anyway, yeah, someday we'll get away from this wad.
asciilifeform: 'gimme a c compiler and i will move the earth' is the notion.
asciilifeform: whole point of buildroot is to reduce pressure on the host os to minimum
mod6: oh,.. i see what you might be getting at. buildroot doesn't come with it because yadda yadda, no kernel needs that to unroll.
mod6: seems to be two seperate things.
mod6: i don't think that because they used to bundle up the kernel as a bzip2 that means that average orc-os wouldn't have that tool set in the default userland,.
mod6: it looks to me that ya, buildroot needs it.
asciilifeform: iirc it asks because kernel src used to ship as one
mircea_popescu: da fuck i care about the extra... what is it, mb ? i got a 200gb blockchain ffs.
mod6: oh for them? yeah, i dunno.
mircea_popescu: prolly cheaper to re-package the damned thing as a tar than to bake in bzip2 dependencies
mod6: i dunno. for whatever reason her OS didn't have those tools ahead of time.
mircea_popescu: why is this required though ? is it just because random idiots decided they need a SPECIAL rar for their ever so special code farts ?
mod6: I believe the package that is required is 'bzip2'.
mircea_popescu: wouldn't a simple tar gz do the job ?
mod6: diana_coman, asciilifeform, mircea_popescu, ben_vulpes, et. al. ok TRB HowTo updated with 'bzip2 tools [including bzcat]'/
asciilifeform: 'The US is also in the process of establishing a new drone base just outside the city of Agadez in Niger in an effort to bolster regional counterterrorism efforts.' << mno attacked FORNOREASON!111
asciilifeform: people laughed when they opened 1982 ibm pc and found working dram chips made of 3, 4 semidead ones soldered 'dead bug' on one another. but those WORKED.
shinohai: I read this as "US Forces attacked by Niggers" http://archive.is/CTtID
asciilifeform: and this is considered salable hardware ?!
asciilifeform: here's a choice lulzgem: 'One-location hammering is based on a previously unknown Rowhammer effect. With one-location hammering, the attacker only runs a Flush+Reload loop on a single memory address at the maximum frequency. This virtually keeps the DRAM bank permanently open. We observed that one-location hammering drains enough charge from the DRAM cells to induce bit flips.' ☟︎
