asciilifeform: dragos ruiu et al
asciilifeform: use one of the legs, or power supply, or whole bus, as antenna.
asciilifeform: reasonably it wouldn't be bluetooth but one of the 'shitmonkey' or what was it called, from snowden-II document, simple short-range radio thing
asciilifeform: including soviet etc.
asciilifeform: incidentally, even supposing the great satan knew how to fit an entire battalion of snitches and three whole atomic bombs into an optocoupler, the fun part re: using standard analogue parts is that YOU CAN GET THEM FROM ANCIENT MACHINES
asciilifeform: https://archive.is/vhyZk << found it, ty punkman
asciilifeform: ;;later tell maqp http://log.bitcoin-assets.com/?date=08-02-2016#1399589 << work us through an example of what a subverted diode ought to do. assume a builder with infinite money and hatred of all things good and bright. ☝︎
asciilifeform: very depressing.
asciilifeform: http://log.bitcoin-assets.com/?date=08-02-2016#1399618 << actually fella reminds me of the medieval folk who tried to build gliders and splat ☝︎
asciilifeform: http://log.bitcoin-assets.com/?date=08-02-2016#1399606 << ahahahahahaha ☝︎
asciilifeform: http://log.bitcoin-assets.com/?date=08-02-2016#1399568 << anybody cached this ? ☝︎
asciilifeform bbl
asciilifeform: that there's the payload, let's have it ?
asciilifeform: what was ~after~ these ?
asciilifeform: http://log.bitcoin-assets.com/?date=06-02-2016#1398559 << l0l! ☝︎
asciilifeform: nobody gives a shit re unpaid leave
asciilifeform: also wtf phf, every place i've ever worked will let you take whatever weeks of ~unpaid~ leave
asciilifeform: and yes, when mircea_popescu wakes up he will no doubt supply us with the mega-insight that if i have no money it is because i have no competence at anything and oughta be boiled for soap asap
asciilifeform: otherwise 'take what you're given, churl, and shuddup'
asciilifeform: re: thread with phf et al: it helps to not be totally broke when negotiating
asciilifeform his work here done, off to pet pet.
asciilifeform polishes imaginary brass 'Arithmetik mit uns' button
asciilifeform: sure, sure, l0lz
asciilifeform: still wanna play ? mircea_popescu can put the 10 in snsa piggy, if he wishes. or we can let the matter rest.
asciilifeform: l0l
asciilifeform: !b 4 ✂︎
asciilifeform: what did mircea_popescu ~think~ would happen here.
asciilifeform: ahahahahahahahaha
asciilifeform: (answer, for the thick, is that your rng, if it works correctly, is EXACTLY as likely to shit out a string that xors yours to 'kill stalin at midnight with table leg' as an equivalent length string of zeros, or any other.)
asciilifeform: but for some reason mircea_popescu understood why this is lunacy, ~then~, but not now?
asciilifeform: funnily enough, last year there was some derp who shat into mircea_popescu's comment section with 'otp doesn't work because rng might burp out N zeros and then what'
asciilifeform: aha. punkman gets it.
asciilifeform: i realize that it cries against every mathematical intuition, but with correctly functioning otp, it makes not a whit of difference what your plaintext is.
asciilifeform: ^
asciilifeform: why not ?
asciilifeform: can he say what the ~previous~ flip was ?
asciilifeform: mircea_popescu finds a coin on the sidewalk.
asciilifeform: mno.
asciilifeform: which is the xor lemma.
asciilifeform: (bias) xor (no bias) == (no bias).
asciilifeform: or you could just skip the otp alltogether
asciilifeform: it sure as fuck matters.
asciilifeform: mircea_popescu is looking at his rng bias.
asciilifeform: as i said, writing own, brb
asciilifeform: i'ma writin' my own, brb
asciilifeform: consider posting the code ?
asciilifeform: 16, rather
asciilifeform: all i see is that mircea_popescu won 32 games of coin-toss with himself.
asciilifeform: what am i looking at ?
asciilifeform bbl.
asciilifeform: this is elementary, and if mircea_popescu comes back and tells us that he had been drinking, i will believe him, and happily forget the whole thing.
asciilifeform: *telepath
asciilifeform: unless you are a telapath, there is nothing useful you can say about a bit which was flipped with probability 0.5.
asciilifeform: suggests that you can magically tell its entire history of flips
asciilifeform: to say that its previous state had any bearing on the face it is showing when you find it,
asciilifeform: imagine you find a coin on the street.
asciilifeform: the mircea_popescu side of the game can only be won if 1) rng is biased 2) he knows how
asciilifeform: to see how ludicrous the proposition is
asciilifeform: that is, with coin flips
asciilifeform: i invite the curious log reader to play the game mircea_popescu proposed with single bits, with a friend
asciilifeform: (and that they were, hence, not crafted specifically to bulldoze whatever magical pattern he put in his strings)
asciilifeform: incidentally, the main reason i'd like a referee, is so that everybody knows that my random 'pads' were generated independently of mircea_popescu's challenge strings.
asciilifeform: this is then exactly isomorphic to my original.
asciilifeform: 'how many' or 'which ones' ?
asciilifeform: vs what
asciilifeform: what's the 3rd ?
asciilifeform: demonstrates significance above chance.
asciilifeform: gotta play with either my original scheme - N sets of 2-pronged - or punkman's - N files.
asciilifeform: if we play with 1 set of alternatives, he has 50% chance of guessing it.
asciilifeform: mircea_popescu has to demonstrate greater-than-chance telepathics
asciilifeform: and that's no fun at all
asciilifeform: if mircea_popescu generates two files, we're playing coinflipsies
asciilifeform: this was punkman's variant
asciilifeform: then we just learn that mircea_popescu can break sha!
asciilifeform: 4) mircea_popescu tells me which of the 100 it was.
asciilifeform: 3) i select one of these, sign, and send to jurov or kakobrekla or somebody, referee
asciilifeform: 2) i xor over each of them with 1MB from a cardano rng.
asciilifeform: 1) mircea_popescu generates 100 files, 1MB (1024^2 byte) in length each. gzips, signs, deedbots.
asciilifeform: i will suggest a handy recipe:
asciilifeform: (this bias, somehow, against xor lemma, surivives xoring.)
asciilifeform: it has to be with mircea_popescu generating the magic strings, because this is how he said he will carry out the telepathy - by selecting specially-crafted biased input.
asciilifeform: see earlier recipe ('variant of game')
asciilifeform: does mircea_popescu want a free 10b or not.
asciilifeform: it cannot create pattern.
asciilifeform: (or doesn't flip.)
asciilifeform: work it on paper. the plaintext (payload), in xor operation, merely flips the key bit.
asciilifeform: think about it.
asciilifeform: mircea_popescu: the output bits - the lot of them - is necessarily as entropic as my key.
asciilifeform: (i will happily collect the win in its stead, like that fool wanted to collect nobel for satoshi!11)
asciilifeform: you are still playing against the xor lemma.
asciilifeform: mircea_popescu: you can use whatever alchemy you like...
asciilifeform: so, for this variant of game, algo would be 1) mircea_popescu generates his string set, signs, deedbots; 2) i xor'em, sign, deedbot at first only the signature; 3) i post one of the xor'ed strings 4) he telepathies which one 5) i reveal my hand, which is the tarball in step 2 6) if he wins, i lose 10b, or vice-versa
asciilifeform: and i'm lazy, he will have to pad'em himself.
asciilifeform: punkman: this reduces to 'same length'
asciilifeform: but in practice longer, because they must be N ~distinct~ strings
asciilifeform: (and L, trivially, is 7 bits or more.)
asciilifeform: if they are all of length L.
asciilifeform: works
asciilifeform: that he gives me, and i xor over, and give back ?
asciilifeform: and anyway that was not the proposed game (because it would not be the least bit interesting)
