mircea_popescu: srsly now, IF
there is such a
thing as a program
that needs crypto-grade entropy at boot
time, it's a piece of shit.
bvt: mircea_popescu: i don't
think it will lead
to any vulnerability or something of
this sort, no; but still
there is a question of what
the early users are (i.e. something in net stack,
that will stick for a long
time?)
bvt: asciilifeform: actually it may be easy
to find early users with ftrace=function ftrace_filter=*random* at kernel command line, and
then get
the users out of
tracefs
mircea_popescu: it's not my fault linux kernel was written by
the zombie herd
mircea_popescu: asciilifeform, various drivers ; various
tables ; samplers ; all sorta crap.
bvt: the O ring needs
to be initialized somehow, zero-filling it may be bad, and keeping
the existing infrastructure for just boot-time entropy collection is not an option; should i look for something simple
that would work for initialization?
mircea_popescu: bvt indeed, if
there's no I
to O overflow,
then O just acts as a cprng, keeps hashing itself

http://btcbase.org/log/2019-08-22#1930162 <<
the plan makes sense, i will implement it.
though i intend
to start from
the 'read data from fg' position, because 1. opening
tty devices from kernel without very dirty
tricks became possible only in 4.13;
bvt: one q
though, per my reading of
the formalization, stretching happens only on I overflow? i.e. if
there is a consumer reading from I, preventing it from overfilling, bytes would never fall into O, and stretching is not
triggered?
bvt: 2. by
tty model of linux, you don't pull data using
tty driver,
the driver pushes
the data
though several abstraction layers. i would have grok
this stuff as well.
there is at least one other driver
that needs
this functionality (for connecting a screenreader
to a
tty), so i can figure out stuff by looking at what it does.
snsabot: Logged on 2019-08-22 13:25:30 mircea_popescu: imo correct design is 16kb
to cpu-cache-sized inner ring buffer, wherein fg material is simply written into a loop, plain ; and from where high quality entropy is read blockingly. whenever
the writing head
threatens
to overwrite
the reading head,
the overwritten bits are instead fed into outer ring

snsabot: Logged on 2018-06-12 20:54:54 mircea_popescu: anyway, your design is dysfunctional in
that (even allowing for it modelling somewhat close
to reality, which i have no faith it does) suppose
today someone gives you a working pill, and june 27th google patches
the hole. and
the someone says "dood, i have nfi, i honestly didn't
tell anyone anything".

thx for reminding me of
that
thread. somehow it seemed obvious
then, lol.
snsabot: Logged on 2019-08-23 12:34:46 spyked: asciilifeform, IMHO
the custom markup idea for new blogotron ain't bad, but it might piss off ppl used
to mp-wp, who still use ye olde html
tags. I'm curious
to hear opinions, given
that I'm working on
this exact
thing for
thetarpit
nicoleci: Ftr, i've been
trying
to get ahold of Ballas at his office in Maryland for
two weeks now.
The first
time I called, receptionist
told me hes only in
the office on Wednesdays, I called back on Wednesday and was
told he left early.
Then when I called yesterday she
told me
that he's working from home
today. Slippery dude.

mircea_popescu: i could write say 8 or so more adnotations
today. will not, because i can't fucking
take moar "o look what i read in washington vice"
mircea_popescu: s retarded skullholes is both a daily irritant and
the actual limit on
the speed of digestion
mircea_popescu: i'd rather donate
to
the democratic party
than give anything
to
the "unmotivated" scum of
the net
mircea_popescu: i really don't ~want~
to give anything
to
these moral repugnants in
the first place.
hanbot: i don't
think it'd require bringing douchebags in; have a list of unsolved refs, assign a reviewer for public submissions (i'd volunteer), award if solved, relationship can end
there.
mircea_popescu: you don't grow
the pantsuit from visual contact with
that dude's bald head directly
mircea_popescu: asciilifeform, it's mildly comedic 1980s dissociated jew fiction. not more immediately dangerous
than say watching star
trek

spyked: hm, it seems
that feedbot forgot
to deliver some posts
today because of
the changes I made yesterday. fixed
this and will include changes in next vpatch
diana_coman: I suspect he just missed
that/did not update his local mp-wp,
that's all

http://logs.nosuchlabs.com/log/trilema/2019-08-23#1930405 << his comment box eats less-than/greater-than signs as 'unclosed htm
tags'. which i also observed on mircea_popescu's www, i
think it is ancient wp bug (of
the 'no one wants
to fix' sort, it'd require a 2-pass parser)
mircea_popescu: yes well, i just looked at
this room, it dun have a "breathe" sign
mircea_popescu: im not re-debugging
this, spent a day year-or-so ago on it, i expect
the resuklts
to be in
the mp-wp
tree!
mircea_popescu: meanwhile, some installs incorectly config'd (ancient ?) eat a
tags
mircea_popescu: i dunno
that it's a bug, just don't leave < floating around.
snsabot: Logged on 2019-08-23 10:25:30 diana_coman: do you still have
the bug re html in comments perhaps?
snsabot: Logged on 2019-08-23 05:19:48 mircea_popescu: i don't intend
to negrate him, as
things stand, so you're more
than welcome
to explore wonderful world detailed in
the further paragraphs of
that comment.
snsabot: Logged on 2018-10-25 15:10:38 asciilifeform: when you add compatibility spackle, serious reader is not saved from reading
the
thing you spackled over -- on
the contrary nao he has
to read
the ~original~ rubbish ~plus~ your spackle, however much it weighs.
mircea_popescu: wouldn't
that read "motherfucker, i have no fucking idea what
the fuck i wrote in here, was i drunk or what, it's illisible!"
snsabot: Logged on 2019-08-22 12:19:27 asciilifeform: imho would be 9000x better
to simply steal
the
technique and port
to e.g. cmucl .
billymg: re: blog work, i'm about
to head out for
the weekend, back early next week. i'll be able
to bang out some more
test coverage based on mircea_popescu's spec on
the
trip and put
together a status/roadmap post when i get back
diana_coman: do you still have
the bug re html in comments perhaps?
diana_coman: feedbot is extremely useful
to
track all
the comments + posts, basically I switched all
to it and it's working great so far;
there was
the deluge of
the after-break stuff coming in
today but it's not a big issue (and it didn't choke on it either so all good)
mircea_popescu: ahh, feedbot conveniently pointed
to me diana_coman 's comment.
this
thing is so fucking useful, making me look like a cyborg
