trinque: justJanne: yeah just average consumer derp is not going
to
tell
the difference between
that and spotify's ogg-whatever
justJanne: ben_vulpes: still, compared
to all
those 9000$ expensive audio cables, or Beats headphones, lossless FLAC has an advantage over 128kbps mp3
☟︎ mircea_popescu: dawg im impressed,
this is like black madonna material.
ben_vulpes: he'll blow a billi, and never
touch software again.
trinque: yup,
the people who listen
to him and beyonce aren't even paying for spotify
ben_vulpes: anyways,
Tidal was a flip onto Jay Z who has yet
to learn how horrifically expensive software is
to build and maintain in fiatland.
trinque: jay-z is probably
the best of
the rapper-turned-entrepreneurs, yes
justJanne: The difference between Dr Dre and Jay Z? Jay Z’s product actually is something more
than marketing speech
trinque: damned hilarious if so, dunno about
that
trinque: heh looks like
there's some noise about dr dre being behind burning man
justJanne: and
the sound quality,
tbh, is great. Just not worth 20$ a month
justJanne: I found a way, but now I have a few
thousand files encrypted,
the corresponding PBKDF2WithHmacSHA1 encryption keys, but was
too lazy
to find
the client-side salt for
that
trinque: "so
totally not spotify you see"
trinque: streaming service
that got whoever's still considered "famous" in music
together, stamped
their faces on
the
thing
justJanne: A music streaming service
that streams lossless unedited FLAC files
justJanne: (yes,
Tidal uses a native plugin for in-browser DRM)
justJanne: the in-browser DRM is a native binary
that is pretty much stripped of any information, actually kinda hard
to use, but
the Android version of almost everything is stupid
mircea_popescu: kinda funny
that drm never got as clever as viruses. even back when both
these were clever,
the ms-dos era.
ascii_field: justJanne:
traditionally copy protection is implemented, where
the rubber hits
the road, by poor schmucks who aren't dumb enough
to believe
that it 'works' but still gotta collect
that salary, and so 'are only following orderz'
justJanne: but
then I discovered
they have an unobfuscated android app, so I got lazy and started instead decompiling
that one
justJanne: I spent
the past days doing
the same – actually cracking DRM of
Tidal
ascii_field: it's really just a ritualized version of
the familiar cracking of w4r3z
ascii_field: justJanne:
that last one was called 'the bomb' where i went
to school
justJanne: we did lots of optimizations in
the past weeks, homework
this week is "you have
this blob of binary, find out what it does, circumvent its checks"
justJanne: c has no
true, nor real false. But it can return 1 or 0
mircea_popescu: <justJanne> so everything
that is not 0 is automatically
true < ?
justJanne: so everything
that is not 0 is automatically
true
justJanne: so
the ! is necessary
there
to
turn -1 into 1
justJanne: mircea_popescu:
the overall question is
to implement
the < operator
trinque: teaches
the best
to hold back
too;
that's always good
trinque: learn how
to pass
the whole class
justJanne: ascii_field: homework is done in groups of
two here at uni, so people learn how
to do
teamwork
justJanne: the only optimizable place would be
the point where we do a
two-out-of-three logic
justJanne: we got it down
to 8 operations, but others got it in 7
justJanne: the question was
to implement
the < operator on int with boolean logic
justJanne: okay, I’m kinda in a hurry – anyone know a fast way
to do
two-out-of-three in boolean logic with less
than 5 operators?

This may
take a few moments.
mircea_popescu: planation for
this is
the deeper genital cavity of S. bilineata, which stimulates
the males more
than when mating with guppy females."
mircea_popescu: "Male guppies (Poecilia reticulata) have been observed
to forcefully copulate with females by
trying
to insert
their gonopodium (male sex organ) into female’s genital pores, whether or not
they are accepting. Sometimes, male guppies also
try
to forcefully mate with Skiffia bilineata (goodeid) females, which resemble guppy females and
tend
to share
the same habitat, even when guppy females are available. A possible ex
mircea_popescu: in other news, "In
the newt species Notophthalmus viridescens, males carry out a courtship behavior called amplexus. It consists of males capturing females
that do not want
to mate with
them and using
their hind limbs
to grasp
the females by
their pectoral regions." << check out
the newt pua!
mircea_popescu: i mean if you have your own iron you don't need it's one
thing, but otherwise... best own
the box.
mircea_popescu: hm, i recall
there were supply problems in
the eu. but maybe worth a
try.
Jautenim: mircea_popescu can
they be ordered from
teh EU?
ascii_field: Apocalyptic:
the precaution
taught in school is
that 'prng is bad because enemy might learn
the seed.' which is a 'lie of omission' - given
the existence of a relation between bit N and bit N+1, enemy may have
the means
to infer N+1 (and N-1) from N
mircea_popescu: Jautenim or you could order a pogo and help
that effort along ?
Jautenim: I'm planning
to rent a cheap vps and run it more or less full
time
Apocalyptic: but
that isn't relevant
to
the "tests" discussed
Apocalyptic: yeah, he seems
to argue
that since it's deterministic it's no good
Apocalyptic: mxtm, Mersenne
twister seeded with a strong seed is also a defined sequence
ascii_field: 'The yeasts could be locked in secure laboratories, worked on by screened employees. Sharing
them with other scientists without government permission could be outlawed.' << what even.
mxtm: yeah,
that's what i was
trying
to convey, it's a defined sequence
ben_vulpes: Jautenim: not a great deal, i
think mod6 ran one in less
than 200MB of RAM recently, but
that was with asciilifeform's 'orphanage
thermonuke'
mircea_popescu: mxtm it's not a REAL entropy source. it's a defined sequence
that may be confused for an entropy source, if one's definition of entropy is
test based.
mxtm: Apocalyptic:
then how would it be an entropy source
ascii_field: Apocalyptic: not merely 'pi', but all
transcendentals
Apocalyptic: it is actually conjectured
that pi contains all
the possible finite sequences you can
think of
mxtm: Apocalyptic:
the nth digit of pi doesn't change
Jautenim: I came
to ask what are
the rough requirements
ascii_field: but with
the fact
that once enemy catches on, he will laugh himself
to death (this being your only hope)
mxtm: it's
the same always
ascii_field: justJanne: nothing
to do with 'slow' (baily-borwein-plouffe algo is fast, gives nth digit)
justJanne: the issue with pi is
that it is a very slow RNG
mircea_popescu: justJanne
the application here is
that, if i give you a string of random numbers which unknown
to you are
the nth digit of pi onwards, you may
think you have entropy by "tests".
ascii_field: ergo, utility for battlefield crypto does not reduce
to mathematical
tests
ascii_field: justJanne: but you will notice
that it -passes
tests-
ben_vulpes: trinque: i still have no idea how
to do a local overlay for a package pulled from portage
Jautenim: lurker at contravex,
trilema &
the logs for some
time now
trinque: interesting; I'll consider
the dieharder source code a starting point for further research.
