mircea_popescu: ben_vulpes at least
theoretically auto_ptr was
the standard replacement for unique_ptr, with
the difference
that it can also be copied, not just moved. so in point of fact plain replacement of one for
the other is bound
to cause grief.
mircea_popescu: double carry ?
this sounds eerily familiar in retrospect.
mircea_popescu: asciilifeform
the only practical use may be
that it's perhaps cheaper
to count l's
to exclude unoverflowing mults and
then appl ythe double reg mult
to
the remainder,
than
to apply
the double reg mult uniformly
throughout.
diana_coman: actually I found
the paper
too meanwhile, ping me
diana_coman: asciilifeform, a search for
that
thing
turned out what seems
to be
the MSc
thesis behind it if
that's any help
a111: Logged on 2017-04-29 05:56 mircea_popescu: ben_vulpes whart's
the difference between auto_ptr and unique_ptr, dja know ?
pete_dushenski: lol speaking of special interests going at each other, "She’s
the Alternative for Germany’s new co-frontrunner despite a great divergence from
the party’s
typically conservative, xenophobic portrait. Alice Weidel, an openly gay economist, was nominated as
the anti-immigrant, far-right party’s chief candidate on Sunday, set
to run alongside AfD co-founder Alexander Gauland in September’s federal
mircea_popescu: mats i'm pleased
to see
trilema moved
teh overton window so.
mircea_popescu: hey,
the whole point of even buying
tickets at
the Decaying Empires show is
to watch special interest groupas gfoing at each other.
pete_dushenski: "Oxford University has apologised for saying
that avoiding eye contact could be "everyday racism" after it was accused of discriminating against autistic people." << in other british sads
that i can only wish were
trolls.
mircea_popescu: alrighty,
this is
turning out
to be more interesting
than i
thought.
mircea_popescu: asciilifeform you will have
to consider
the parity of
the
two items
to decide if you go by N or N-1.
pete_dushenski: shinohai:
there ain't no happening like an unhappening. just priceless.
mircea_popescu: anyway, as i said : i
thought ~this~ is why computers even use binary in
the first place.
mircea_popescu: we also notice
that 0 +1 = 1 which being < 3 we lost bits.
mircea_popescu: meanwhile 255 * 255 does not overflow ; you know
this because 8 + 8 is not < 16.
mircea_popescu: for convenience, consider 16 bit registers : 8245×8 = 65960 which overflows. you know
this because 0010000000110101 x 0000000000001000 ie 2 + 12 = 14 which is < 16.
mircea_popescu: so
then. if
these
two added
together are less
than N you've lost some high bits.
mircea_popescu: if l1 of x1 added
to
the l2 of x2 exceeds N
then it doesn't represent x1 * x2
mircea_popescu: if
two numbers of lengths l1 and l2, with l1 and l2 < N are multiplied, and
the result is less
than l1+l2 bits long,
then it has overflown.
mircea_popescu: to put it another way,
two N-bit items muliplied so
they yield a M bit result, where M < N, overflowed
the buffer.
mircea_popescu: asciilifeform isn't it
the case
that if
the result was 0-led you'd know
the product had overflown ?
mircea_popescu: i
thought
this was
the reason computers EVEN USE binary in
the first place.
mircea_popescu: ahem ? if
the product of
the leading q bits isn't equal
to
the leading q bits of
the result, you have overflow.
jhvh1: asciilifeform:
The operation succeeded.
mircea_popescu: conceivably he might also explain how
to make a gentoo
that works, and in
the process of
trying find out a few
things for himself.
mircea_popescu: graybeard, perhaps not entirely objectionable. ~the iota of value in
the whole pile of idiotic kids
trying
to bypass mp's "talking about bitcoin doesn['t make you part of bitcoin" by hanging out in ##crypto and pretending like
they know maffs.
mircea_popescu: anyway, i invited steve arnold aka sarnold over ; plox
to voice / explain how
to register his key if i'm not around.
mircea_popescu: see, bukharin who idiotically will not go
to china
to hang out with a 30yo deng xiaoping also pays $9 a month "for his
team"
to github.
mircea_popescu: o check it out, github has a "pricing"
tab i never noticed before. $9 per user per month ? really ?
mircea_popescu: in other lulz, le pen has a lengthy list of other-provinces-generals
to name in various places once she wins. such roman empire.
mircea_popescu: not somebody is an imbecile, like adlai et al,
to actually dose
themselves.
mircea_popescu: which is a perverse sort of reminder :
taking
the usg seriously, IN ANY WAY, is what
the usg lives off if.
mircea_popescu: at any rate -- it is worth pointing out
that
the original "charges" proferred by
the sops
terrorist organisation were dropped ;
the current "sentence" stems from posturing around a youtube video
the guy made discussing said "charges".
mircea_popescu: ”The U.S. government decided
today
that because I did such a good job investigating
the cyber-industrial complex,
they’re now going
to send me
to investigate
the prison-industrial complex,” he said,
thanking
the government for providing “free food, clothes and housing as I seek
to expose wrongdoing by
the Bureau of Prisons officials and staff and otherwise report on news and culture in
the world’s greatest prison sy
mircea_popescu: the pretense
to be
taken seriously is so fucking lulzy by now. i expect next is a shoe banging moment, yes ?
mircea_popescu: from
the monkeystan link : "Ms. Luz Lujan, his BOP contact, refused
to provide him with copies of program statement rules". but ofcoars. and "ms" luz lujan is going
to do no
time for
this, because hey, good soviet.
mircea_popescu: ps
things were always
thus; but
there is a particular danger when a party has had
too much power for
too long: its members cannot compete
to attack
the enemy so
they attack each other instead. If future commentators identify a "missing generation" of politicians who were in
their
twenties during
the
Thatcher years,
this will have been
the cause."
mircea_popescu: to briefly revisit kochanski, "I was subsequently elected
to
the post of Research Secretary of
the Bow Group, which meant
that I was
the general editor of its published papers from 1989
to 1990. My abiding impression of
the foothills of
the Conservative Party at
the
time is of a world where people eyed
their friends suspiciously and if
they saw signs of possible
talent
then
they knifed
them before
they became a danger. Perha
