apeloyee: A <4^K, so the above strictly >(A*4^K)/N - A.
apeloyee: let rewind. A*R = A*(4^K - B)/N = (A*4^K)/N - A*B/N; as B <= N, then the previous >= (A*4^K)/N - A. clear?
apeloyee: what step is a problem?
apeloyee: A - N*floor(A*R/4^K) < 2*N <- do you agree with this? (the proof is unnecessarily complicated in that paste)
asciilifeform: was 3 in barrett's original proof. but with doublewide c, looks like only 1 ? ( though i do not yet have a proof for this )
asciilifeform: i was discussing a 'shiftless' doublewide barrett
apeloyee: painful, but probably beats a larger muliply
asciilifeform: apeloyee: please make a new one ? and give to trinque , signed with old
asciilifeform: why didja make a key that expired in weeks, apeloyee ?!
asciilifeform: oh hey it's a clock item
apeloyee: per spec the bitness is a power of two
mircea_popescu: i'm just being a pain.
asciilifeform: apeloyee: Shift(A, S mod W) leaks S mod W on machines without a barrel shifter.
mircea_popescu: a hey that's actually an idea.
asciilifeform: ln 41: Scratch2 := Shift(A, S1);
asciilifeform: ln 36 : A := Shift(A, S mod W);
apeloyee: i'm all out of gas mask cans! HOW does a FIXED shift leak?
trinque: apeloyee: you tried sending a private message to deedbot with !!up ?
a111: Logged on 2017-09-21 16:22 asciilifeform: !~later tell apeloyee i studied your algo, it (aside from truly massive cost, that would annihilate savings from newton, or barrett, or just about any other trick) ~still leaks~, because shifting by >wordsize is a fundamentally different op from shifting <wordsize; and the only way for this to not be true is for all shifts to happen as a series of wordsize shifts; and a shift by ffawidth-1 (max shiftness) would then consist of ffawor
apeloyee: a shift by multiple of the wordsize takes considerably less time than by not << and a multiply takes more time than add, what.
asciilifeform: a shift by multiple of the wordsize takes considerably less time than by not
mircea_popescu: why can't i grep "hurr" over a cat #trilema bots ?
mircea_popescu: ben_vulpes technology is built by steps. so far, being able to put in machine terms a "ask all the bots see which one mentions 'payments' as a string" is a legitimately useful ability.
ben_vulpes: and what, a machine-understandable description of what each extra-spec command does? i didn't think anyone here operated machines that /thought/.
mircea_popescu: but practice aside, shouldn't i have the ability to query a bank of seated whores, "what can you do ?"
mircea_popescu: well the original case was to end up with a proper universal api.
lobbesbot: mircea_popescu: (help [<plugin>] [<command>]) -- This command gives a useful description of what <command> does. <plugin> is only necessary if the command is in more than one plugin. You may also want to use the 'list' command to list all available plugins and commands.

ben_vulpes: http://logs.bvulpes.com/trilema?d=2017-10-5#216206 << i have acquired a few afk crises which have eaten a bunch of time since the move.
asciilifeform: 2 ^ 4096 is a 4097-bit number
a111: Logged on 2017-08-18 23:01 asciilifeform: 'That followed the General Services Administration removing Kaspersky from an approved-vendors list in early July and a congressional push to pass a law that would ban Kaspersky from being used by the Department of Defense.'
asciilifeform: '...identifying the files through the contractor’s use of a popular antivirus software made by Russia-based Kaspersky Lab, these people said.' << lol re http://btcbase.org/log/2017-08-18#1700468 smear ☝︎
asciilifeform: a div0 does not have a defined result, and any program that attempts it is resultingly nonsense. the ancients got this right.
mircea_popescu: in that it terminating the program at a certain time it leaks... a certain time.
asciilifeform: however div0 trap cannot leak timing, because it is a fatal condition
asciilifeform: 1 is a possible output of a - b. or whatever other combinatorics.
mircea_popescu: 1 is not a divisor of anything, whadda ya want from me.
asciilifeform: reals dun exist on a comp
asciilifeform: as in, i get to , e.g., r = x mod ( a - b ) for some a, b
asciilifeform: mircea_popescu: 'holes' in arithmetic suck, because they are inescapably branch conditionals. if i could not prove that div0 is impossible in the course of, e.g., modexp intermediate steps, ffa would be a wholly impossible thing.
asciilifeform: ( modulo 0 is disallowed, it is same as a div0 )
asciilifeform: modulo 1 is a permitted op
mircea_popescu: but not allowing 1 as a divisor is not some sort of big deal.
asciilifeform: otherwise we'd use montgomerization and call it a day
asciilifeform: ( we're talking about a 3fold speed difference )
a111: Logged on 2017-10-05 16:07 asciilifeform: note that this is a 4097-bit ( in actual ffa, 8192b ) constant.
asciilifeform: btw re nypd, oct. 23 2014 : 'Thanks to a massive $160 million investment, the New York City Police Department is on its way to receive a combination of up to 41,000 smartphones and tablets. Known as the NYPD Mobility Initiative, which will be mostly financed by criminal asset funds provided by the Manhattan DA's Office, the goal is to provide the the city's law enforcement with tools that can improve and streamline their overall work
mircea_popescu: dja understand that had they paid 1k per phone, which a) the ipad never cost and b) volume discounts, they'd have justified less than ONE QUARTER of what they actually spent.
a111: Logged on 2017-09-05 13:25 asciilifeform: meanwhile, in monkeystan, https://archive.is/6t8bO >> 'The NYPD has to scrap the 36,000 smartphones it gave cops over the past two years because they’re already obsolete and can’t be upgraded, The Post has learned. The city bought Microsoft-based Nokia smartphones as part of a $160 million NYPD Mobility Initiative that Mayor Bill de Blasio touted as “a huge step into the 21st century.”'
mircea_popescu: maybe they googled both, one seemed like a corp.
asciilifeform: mircea_popescu: could easily be a matter of weight. iirc each of the prev. uk purchasers, got >1
mircea_popescu: or maybe he just cashed in whatever was left and paid usg for a new mortgage, or maybe was actually shot and left to bleed somewhere, or or or.
asciilifeform: lol maybe mike_c found his new FG's to be a downer
a111: Logged on 2017-08-13 20:36 mike_c: i know, right. It's frustrating prioritizing time. Didn't have time to hang, definitely not to work, so felt weird dropping in once a month and saying "hey, haven't done anything, don't have time to do anything"
jhvh1: mircea_popescu: mike_c was last seen in #trilema 3 weeks, 3 days, 13 hours, 38 minutes, and 44 seconds ago: <mike_c> congrats! I did that a long time ago too. Good luck with it.
mircea_popescu: by the way, since we're doing PSAs : how about NOT doing dumb shit like this, as a matter of well maintained policy, so we have a chance in hell of knowing whether you've been fucking kidnapped as opposed to you know, merely unreliable in the family way.
mircea_popescu: maybe he got a new gf or something.
asciilifeform: iirc it was a move out of britanistan.
mircea_popescu: he said something about a new job or moving or something, i'm foggy on details.
trinque: I'm in the position to boop a qr code on an airgap machine for the signed tx
trinque: shall yes, though there are still a few human steps in there today.
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: 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.
asciilifeform: note that this is a 4097-bit ( in actual ffa, 8192b ) constant. ☟︎
asciilifeform: in other noose, asciilifeform derived a simple constant-time variant of barrett. short enough to put in the l0gz:
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: 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: aaand in other "after graduation i plan to spend a year in africa doing charity work" news, http://i.4cdn.org/hc/1501923521316.jpg
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.
BingoBoingo: lol, a lot of people would be surprised how bouncy concrete is
BingoBoingo: Not yet, just passed a house committee
mircea_popescu: a yeah, what happened to her ?
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
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.
a111: Logged on 2016-04-08 22:17 mircea_popescu: this guy, thinks he's a nigger. got a bad scar and missing eye.
asciilifeform: wat's a drexl
asciilifeform: mircea_popescu: it's a fungus. mircea_popescu in particular is fond of reminding asciilifeform that fungi dun have with what to 'try'
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: yeah, i think emerge a trb would be the ticket, no?
asciilifeform: trinque: can't build musltronic elf on a glib-infested linux
asciilifeform: 'gimme a c compiler and i will move the earth' is the notion.
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,.
mircea_popescu: da fuck i care about the extra... what is it, mb ? i got a 200gb blockchain ffs.
mircea_popescu: prolly cheaper to re-package the damned thing as a tar than to bake in bzip2 dependencies
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 ?
mircea_popescu: wouldn't a simple tar gz do the job ?
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: 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.' ☟︎
deedbot: http://trilema.com/2017/a-better-man-than-i/ << Trilema - A better man than I ?
hanbot: 3rd time this week, 5th week in a row, if i'm not mashing ctrl s in my sleep yet i'm sure it's coming.
shinohai: "It's known that the limit is small, and this was a design flaw in BIP16 that was not noticed until several years later."
asciilifeform: 'The consensus rules do not permit spending from a P2SH output that requires a >520 byte push.' ahahahahaha
asciilifeform: ^ for completeness would also say ' a bsd would, in theory, work ' but practice has not confirmed : http://btcbase.org/log/2017-08-06#1694302 ☝︎
asciilifeform: ( btw is it clear that buildroot is only part of the trb universe because we dun have a musltronic linux to do ordinary stator builds in ? )
