asciilifeform: nor emit information re the input or output via timing sidechannel.
asciilifeform: nor give some segments of the input bitstring more influence over the output than others.
asciilifeform: it is more that i cannot prove to my satisfaction that it does not skew the distribution .
mircea_popescu: http://btcbase.org/log/2017-11-07#1733464 << i still don't follow how you figure the approach elides some primes. ☝︎
mircea_popescu: "pivot" being the anglo word for this.
mircea_popescu: it wants to be whatever usg's silicon valley politruks appear to be willing to put stalin's notes behind that season.
asciilifeform: this is the fate of all 'we don't have an ideology' derps ☟︎☟︎
asciilifeform: the scihub thing isn't even sure what it wants to be , 13337 w4r3z, or 'service'
mircea_popescu: but otherwhise there's no excuse available to the chuchka that "washing is too hard and besides rubbing against a tree trunk is a close approximation"
mircea_popescu: or whatever, if they don't feel like it, like eg ben_vulpes doesn't for his paste service, let them not to
a111: Logged on 2017-11-07 17:29 apeloyee: you want sci-hub to wwork for phree?
mircea_popescu: http://btcbase.org/log/2017-11-07#1733438 << let them learn how to fucking use technological civilisation, get a deedbot account and fucking charge like sane people. ☝︎
a111: Logged on 2017-11-07 17:27 apeloyee: ......p_n are independent and uniformly distributed, then the probability of tuple of these being chosen is the same (by definition of independence), and because CRT gives a bijection, all outputs are equally likely. did I repeat myself enough?
a111: Logged on 2017-11-07 17:14 asciilifeform: ( why is there EVER EVEN ONE ?! )
mircea_popescu: http://btcbase.org/log/2017-11-07#1733423 << because you keep clicking on them. ☝︎
asciilifeform: i'ma have to chew on this.
mircea_popescu: asciilifeform not so, because the gap's a cone not a rectangle
asciilifeform: but i have no proof of this yet.
asciilifeform: afaik all of the bits are equally likely to 'need flipping'
mircea_popescu: in general so after 16773120 bits were produced by FG, 4096 were added to last bit and 1 to first. pyramidfixer.
a111: Logged on 2017-11-07 17:03 asciilifeform: what ought to do instead, is to rngize the bottom Q bits, where Q is log2(estimated prime gap at the current bitness, times severalfold engineering margin)
mircea_popescu: http://btcbase.org/log/2017-11-07#1733418 << no, actually : should generate new prime by adding a byte to the extant number that failed on a PROBABILITY based index. ie, adding to offset 0 much less probable than adding to offset 4090 ☝︎
asciilifeform: i.e. generator of nth prime in O(1) time. nobody's got one and i don't expect anyone will.
a111: Logged on 2017-11-07 16:41 asciilifeform: but as i currently understand, my q reduces to 'find The Formula For Primes' (tm)(r), a millenium-long headache for mathematical folx , to this day unsolved.
a111: Logged on 2017-11-07 16:21 apeloyee: I must say that I dont understand how "exponent 131074 reduces to exponent 2 somehow", and what CRT has to do with it
mircea_popescu: http://btcbase.org/log/2017-11-07#1733356 << for completeness i originally read "largest prime factor", and intuitively thought i see the proof, but meanwhile that also collapsed. ☝︎
asciilifeform: 'That day, Polygon[13] and Kotaku[12] published articles calling the Kekistan flag an “alt-right” and “white nationalist” symbol' << lol
shinohai: https://www.antena3.ro/actualitate/social/o-organizatie-anarhista-prezenta-la-protestele-de-duminica-441087.html <<< Is my Romanian really that terrible, or are they calling a meme an "anarchist organization" ? ☟︎
asciilifeform: meanwhile, in the pleasures of overflowsandpointerslang , https://github.com/google/syzkaller/blob/master/docs/linux/found_bugs_usb.md
asciilifeform: they're happy to fly boeings into sea / towers / etc. remotely. nobody will even fart at ntp/bbc/etc.
asciilifeform: hm, nothing pertinent in there. odd.
asciilifeform: not only is 'turn off bbc/nasdaq/ntp to Help Nail A Terrorist' an unremarkable proposition in comparison, but prolly has existing, fully-robotic infrastructure ready to roll.
asciilifeform: we're speaking of the same empire who did live-fire biowar tests on own population, in the subways, 1950s
asciilifeform: but there are still occasional folx who seem to think 'But They Wouldn't...'
asciilifeform: it's a regular thing.
BingoBoingo: For a while big mediterranean cables were snipped similarly to likely same effect
a111: Logged on 2017-07-04 03:09 asciilifeform: in other unsurprises, 'Corrupt data that accidentally flowed out of a NASDAQ systems test caused the share prices...'
asciilifeform: moar famously, to nasdaq
BingoBoingo: <asciilifeform> ( i wouldn't put it past'em to 'technical glitch' and turn off bbc for a few min. to get you to up your wattage, say ) << They do it to comcast
asciilifeform: see, for instance, the ancient thread where we anathemized ntp.
asciilifeform: ( i wouldn't put it past'em to 'technical glitch' and turn off bbc for a few min. to get you to up your wattage, say ) ☟︎
asciilifeform: before that it only has what crumbs enemy throws from the table.
asciilifeform: q is what is the best that can be done with simply a radio.
asciilifeform: just as he will take advantage of having airplane, and satellite, and armies, etc.
apeloyee: consider that the enemy will certainly take advantage of your willful ignorance of atmospheric conditions (as known from bbc,etc), as you will up the power
asciilifeform: but these rely on existing infrastructure, like flea relies on dog. asciilifeform's q was specifically re self-contained structure.
asciilifeform: or, more elementarily, 'wardriving' ( 802.11 crypto was broken to death quite recently, note )
asciilifeform: otherwise i'd have started the thread with unsecured satellite relays ( which do currently exist )
asciilifeform: it's a thing until it isn't
apeloyee: no externals plox << opportunistic use is a thing
apeloyee: can add a phase offset so that they are in-phase at receiver. N stations, more than N times SNR increase, but opens to attacks based on partial knowledge
asciilifeform: ( the british-style 'can i hear bbc?' nonsense, i will dismiss out of hand, no externals plox )
asciilifeform: as for atmospheric conditions, station has no way of knowing them ☟︎
asciilifeform: for the tx process per se.
asciilifeform: sorta how i got to the positional modulator thing -- can you take advantage of the fact of having 2+ dispersed stations.
apeloyee: if you needed 1W before, add a relay half-way, need 0.25W for you and relay nao. generally private relay should be a lot closer to sender. needless to say relay must re-modulate.
asciilifeform: also must note that if the relay is controlled via radio, you've re-created orig problem in miniature.
asciilifeform: this is separate item from 'can do on demand' tho.
apeloyee: more: set up a site, bemoaning "radio intruders" on $band, stream from several nearby radios on it. the recipient can then improve SNR by subtracting whatever interference (from your POV), or estimate atmospheric conditions
a111: Logged on 2017-08-30 20:08 mircea_popescu: and the shower has a pair of buttons : if you increase the hot water debit, this drops pressure for the hot pump, which kicks in, dropping pressure for the main pump, which kicks in. and vice-versa.
asciilifeform: mircea_popescu iirc actually does this.
apeloyee: more crackpot ideas: live in flyshitville, can then have ample warning about enemy detection equipment, and plenty of RF emission by and neighbors' equipment to hide behind ( but few neighbors, important for SNR)
asciilifeform: ( which will last maybe 40 min. when actual war, but nobody seems to give a shit. ) ☟︎
asciilifeform: the empires solved this with satellite.
asciilifeform: orig thread is most properly concerning small radios, deep in enemy territory.
asciilifeform: e.g. ru horizon radar , eats what, half a MHz of sw, and betcha they have a massive garbage bin to put the complaints from 50 years into.
asciilifeform: observe, the problem dun exist if you already have your own pyongyang and can happily put a megawatt station there and invite whoever objects, to pound sand up his arse ☟︎☟︎
apeloyee: 'maximize # of bits that can be sent before you gotta move' << this mostly involves choice of locality. "check if the map matches the locality. If it doesn't - change the locality."(R)(C)
apeloyee: transmit slowly enough. enemy's cost to proportional to time
asciilifeform: could restate problem as 'maximize # of bits that can be sent before you gotta move'
apeloyee: if you miss some time period, got to capture moar.
apeloyee: yes, involves capturing and comparing traffic from multiple points, because each individual bit gives very little confidence
asciilifeform: personally i'd be satisfied with a 'it costs all the king's horses and all the king's men' item.
apeloyee: and? understand I claimed that it's possible to find you, not that it's easy or cheap
asciilifeform: ( currently there are 0. )
asciilifeform: was still speaking of the scenario with 1 station
apeloyee: df for usg for free << correlation attacks work but are neither easy nor cheap. if they only exchange 10% of the traffic, will take 10x as long to find you, unless they know the key
asciilifeform: now this theoretically tru
apeloyee: hogging sw spectrum will be a simple way to make new enemy. << can reach a mutially beneficial agreement. the more transmitters, the more channel capacity, until the distortion is above noise.
asciilifeform: what happens is that 5-6 pensioners notice 'noise' and get in their trucks and df for usg for free, for a month, if it takes a month
asciilifeform: i dun see why this is necessary
apeloyee: or they must send strgraight to enemy
apeloyee: gotta exchange among them all traffic.
asciilifeform: plus a good number are in orbit, so narrow down where to look quite effectively.
apeloyee: an' they have 30000 SDRs to keep the siege? physical objects?
asciilifeform: asciilifeform's original q could be restated as 'how to achieve same thing as satellite, but without any'
asciilifeform: incidentally the problem as originally stated, 'communicate across planet with a few watt, reliably, unjammably, and as close to undetectably as possible' was obsession of usg in 1940s-50s; and was declared 'solved enough' when satellite was built.
asciilifeform: it's a limited resource and whatever crowned idiots sit on whatever thrones, will claim it
asciilifeform: existing gestapo aside, consider also future enemy. because even when the empires of today are forgotten, hogging sw spectrum will be a simple way to make new enemy.
asciilifeform: because per orlov 'collapse never happens for everyone, it only happens for a particular you, one at a time'
asciilifeform: yet folx keep showing up to work. ☟︎
apeloyee: understand, they can't keep sieges on 10,000 вредителей. will go bankrupt.
asciilifeform: what, gotta break into every single neighbour and see if they have one, lol
asciilifeform: otoh if it is in the house next to mine, i have no way of knowing it
asciilifeform: but it is quite different problem from the original thread's.
asciilifeform: if apeloyee or whoever wants to get past the tank column, mine field, etc. and demolish the receiver -- i'll clap, what.
apeloyee: most of the processing is local << if a known вредитель, that means siege. otherwise they need to exchange ~approx as much data as can be fit in spectrum. obv can't reuse the very same spectrum. hence lasers/sound/cables. can be sabotaged. them low noise receiver must cost quite some $$$.
asciilifeform: upstack : a 1w transmitter , under right conditions, can be heard across atlantic. tricky bit is how to extend this to belownoisefloor; and how to make in 'wrong' conditions.
asciilifeform: and those who want to be gassed faster, gotta work harder, earn it..
asciilifeform: asciilifeform has nfi why he's been standing in line for years, to be gassed. evidently it is a scarce and rationed thing, like everything else in usa.
