mircea_popescu: next
the usg is going
to get off its ass, discover
the whole rapereum "ecosystem" was $7600.
mircea_popescu: asciilifeform understand
this isn't a matter of
testing specified bitfields, but specified ~processes~
mircea_popescu: pass-fail
tools notoriously horrendous measurement instruments.
mircea_popescu: and in
the process see also
that ent is not a very good measurement
tool.
mircea_popescu: the whole discussion is, given a stream of perfect entropy, how
to construct known-degree-of-badness out of it.
mircea_popescu: asciilifeform no
that's exactly what we're doing. controlledly-bad-level entropy.
mircea_popescu: a is also
twice as strong, because obviously b will flip on average half
the bits it sets. but is
this ACTUALLY half ? ie, how do yo umeasure unrandomness ? b is much more strongly patterned
than a.
mircea_popescu: as alf points out, a is "better" in
the sense v-n debiaser kills b, if
this is a better. unclear.
mircea_popescu: (ie, i dun have an answer for it myself, nor know how
to get one.)
mircea_popescu: poor ben_vulpes has been silent since
the blessing of wtf 10 minutes ago.
BingoBoingo: <mircea_popescu> wtf, newswriting not dictionary boating accident << Cleanup ongoing. Probably ought
to write before baking brain in heat or sleep and proofread before publishing. /me resets "Days since linguistic boating accident" sign back
to 0 days
mircea_popescu: asciilifeform
there is
that, yes. but we're doiong
this for instrumentation in
teh lab not for any other purpose. it's a
tracer for entropy, like
the shit
they make you swallow
to see your stomach.
mircea_popescu: as in, balance it according
to a calculation, rather
than according
t oa feeling.
mircea_popescu: which allows you
to correctly balance your
tester irl.
mircea_popescu: in a sense. it has multiple utilities, it allows you
to
try and guess (numerically) whether for instance better entropy or more passes are useful for rabin miller
mircea_popescu: then we feed it into entropy-dependent processes (say
the rabin miller
test, as discussed yest) and see what comes out.
mircea_popescu: M' is now a "known low entropy bitfield". we know it
to have degraded by 100/1Mb or w/e
the case may be
a111: Logged on 2017-07-10 19:50 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: ben_vulpes here's a high pay grade question for you : of
the
two models of "controlled de-entropy" i spawned in a week, specifically a) count of randomly placed flipped bits, as in
the discussion with you re
that and b) string of randomly initiated, n bit long SET bits, as discussed in
http://btcbase.org/log/2017-07-10#1681268 which does
the bitcoin foundation regard as a better candidate for standardization as "the republic'
☝︎ ben_vulpes: byte arrays
to integers for
the m+1, m+2, coercions for byte arrays
to integers, bit arrays for flipping random bits,
ben_vulpes: mircea_popescu: slowlybut surely, expanding
the horizon of
things i understand,
taking
the
time
to make sure i understand each part.
mircea_popescu: "As recently as earlier
today,
the Fake News empire
turned idiot son Donald Junior's gullibility with respect
to a phishing scheme1 into
their latest headline of
the day which
they will use
to sell loyal consumers of
their fiction product on
the "certain end" of
the 8 year
Trumpreich in spite of all
the actual evidence running
to
the contrary of
their narrative supported instead by a complete lack of evidence."
shinohai: fake news is where
the $ is at
these dayz

mod6 reads
the rms
thread
mod6: ah,
that's sweet asciilifeform
mod6: ok neat, i just ran it against my V stuff, seems
to dump out all of
the symbols or whatnot
mod6: now
that i've got
that part in my head, now can
tackle
the rest
tomorrow.
mod6: but now, it's starting
to make sense.
mod6: this was
throwing me off earlier
today ^
mod6: i haven't gone all
the way
through
the W_Mul yet, but just unrolling it as said.
mod6: and gleaned a few
things I didn't notice earlier.
mod6: workin
through
this on
the board. so!
mod6: lol, im probably just dim, but i
think it's
the only way im gonna understand
things
thing
through and
through
mod6: (im going
through by hand here...)
mod6: ok, my bad, i see
those are
the output words for W_Mul, XY_LW and XY_HI.
mod6: are 'Lo : Word; \n Hi : Word;' initialized
to zero on
the first pass
through Col(...) by default?
mod6: asciilifeform: you mind
throwing me your W_Add_D, i don't seem
to have one.
mod6: ah, and
there was a
time when L was not part of
the plan
a111: Logged on 2017-05-21 16:47 asciilifeform: because ALL ops
