asciilifeform: http://btcbase.org/log/2016-06-06#1477813 << >> http://btcbase.org/log/2016-02-26#1415829 ? ☝︎☝︎
asciilifeform: http://btcbase.org/log/2016-06-06#1477797 << what i can't figure out is why they never talk. for srs, what does the schmuck have to lose now ? ☝︎
asciilifeform: magnetostriction is a bitch.
asciilifeform: http://btcbase.org/log/2016-06-06#1477796 << i installed an altogether silent one in february, but i can still hear the inductor sometimes. mega-disappointment. ☝︎
asciilifeform: i'ma off to anti-eat (exercises) brb.
asciilifeform: but they ALL have same problem.
asciilifeform: mircea_popescu: node colouring. there is a whole motherfucking book of them.
asciilifeform: and http://btcbase.org/log/2014-11-23#932035 ☝︎

asciilifeform: for one thing, you need to have the solution to a case of problem to use it as crypto. otherwise you could 'elementary proof of fermat's conjecture is the key!'
asciilifeform: jurov: try to understand what 'proven insolvable' means
asciilifeform: presumably he disobeyed an order.
asciilifeform: and yes appelbaum was a demolition job. but i have nfi what for.
asciilifeform: that was the plan for 100+ yrs.
asciilifeform: where the space is ENTIRELY flat.
asciilifeform: the only genuine 'can solve in ANY way' is in otp.
asciilifeform: in practice opponent ~always~ knows something about the message space.
asciilifeform: and even this does not necessarily suffice.
asciilifeform: you need an avg case proof.
asciilifeform: it is not remotely enough that problem is hard in ~general case~, you have to be able to ascertain that ~your particular case~ is hard.
asciilifeform: mircea_popescu gets it.
asciilifeform: ^
asciilifeform: one simple example that i played with in the winter is 'graph clique problem'
asciilifeform: which is why there are entire encyclopaedias of np-complete problems, but none of them have been used in a working cryptosystem
asciilifeform: and often you have 0 control of this when generating key.
asciilifeform: particular case can be as simple as you like. ☟︎
asciilifeform: all that anybody ever proved is that you can't solve ALL CASES of something.
asciilifeform: see thread about 'particular cases'
asciilifeform: jurov: easy trap to fall in
asciilifeform: or otp.
asciilifeform: but 'omg!1111111 inconvenient!11111 can't reuse key!11'
asciilifeform: i find it also very interesting that all aes-like ('boxes') cryptosystems are direct descendants of rotor machines. which were known to be pseudoscientific even when first built, as vernam existed ☟︎
asciilifeform: picture if every time 'mars didn't rise on schedule' ALL BRIDGES FELL.
asciilifeform: far worse.
asciilifeform: i still can't fully swallow how there is this entire field that isn't certain whether it exists or is simply smelling own farts.
asciilifeform: if they even exist.
asciilifeform: you want actual hard trapdoor problems.
asciilifeform: and everybody pretty much uses fpga clusters for actual cryptoanalysis anyway. so elaborate 'let's zap the miners' trickery is ~pointless.
asciilifeform: method is ages old.
asciilifeform: as noisily as you like.
asciilifeform: and sending the lot.
asciilifeform: you can trivially do it in any ciphersystem by shamir-splitting message into K fragments of which you need J
asciilifeform: it isn't magic - you can still distinguish plausible cyphertexts from rubbish, it just takes more cycles.
asciilifeform: seems like mircea_popescu is reinventing 'padding', that is, dilating message space
asciilifeform: what's lossy here ?
asciilifeform: just like hash collisions.
asciilifeform: in practice you get 1 'yes this is an actual message' and maxint turds.
asciilifeform: this is again true of any system that isn't otp.
asciilifeform: because trivially 2 points.
asciilifeform: if 2+ - can solve.
asciilifeform: if 1 message.
asciilifeform: in ANY case other than otp, you have something to solve.
asciilifeform: same as dh, elgamal, cramershoup.
asciilifeform: ends up reducing to difficulty of discrete log problem
asciilifeform: butyoucan'tsignwithit.
asciilifeform: possibly because it is the one item which actually works with no ifs, ands, buts.
asciilifeform: all roadz lead to otp.
asciilifeform: and you have reinvented otp !!
asciilifeform: mircea_popescu: in order for above to hold true, N must have equal 'mass' to M
asciilifeform: (we have no crypto based on provably-hard cases of provably-hard problem. we have ~some~ crypto based on lousy cases of suspected-hard problem. we have MEGATONNES of crapto based on fuck knows what fuck knows whether problem at all.)
asciilifeform: but it'll have to be a) something you can actually do repeatably on a digital computer + b) based on some reasonably compact hardness assumption
asciilifeform: noshit.jpg
asciilifeform: snake oil with 1,001 ingredients of great rarity and exquisite alchemical aesthetic is still... snake oil.
asciilifeform: numerically manipulating irrationals is not any more algebraic than diddling pi.
asciilifeform: this is similar to 'encrypting' using offsets into pi.
asciilifeform: as an a,b,c triplet of integers ?
asciilifeform: yes but how is it sat down physically
asciilifeform: so what is N physically?
asciilifeform: ah yeah
asciilifeform: a,b,c,N integers?
asciilifeform: aha?
asciilifeform: lel
asciilifeform: l0l
asciilifeform: noshit
asciilifeform: i have nfi what is interesting re the linked piece
asciilifeform: lel does jurov regularly read trashy ru tabloidz ??
asciilifeform: 'Blackburn's lawsuit accuses Oracle management of pushing her to "fit square data into round holes" to make Oracle's cloud services' results look better. She alleges that her bosses instructed her to add millions of dollars of accruals for expected business "with no concrete or foreseeable billing to support the numbers."'
asciilifeform: ;;later tell BingoBoingo http://www.nbcnews.com/tech/tech-news/oracle-whistleblower-suit-raises-questions-over-cloud-accounting-n586276 << possible qntralulz
asciilifeform: win.
asciilifeform: 'This will create a real full node in your browser: your browser will connect to the p2p network and do all of the block verification/serving.' << l0l suuuure. ☟︎
asciilifeform: ages. Most, according to court records, involve online sales and transactions.'
asciilifeform: 0 in 2009. With shipping and other costs, the total was less than $75, according to court records. The printer's buyer was Gersh Zavodnik, a 54-year-old Indianapolis man known to many in the legal community as a frequent lawsuit filer who also represents himself in court. The Indiana Supreme Court said the "prolific, abusive litigant" has brought dozens of lawsuits against individuals and businesses, often asking for astronomical dam
asciilifeform: 'What the 66-year-old Massachusetts man didn't know then is that he would spend the next 6 ½ years embroiled in a complicated and confusing legal dispute in Indiana over that printer, which, according to its buyer, was broken. He would find himself liable for about $30,000 in damages. He would pay a lawyer at least $12,000 in his battle to escape the legal mess. And it all started with a piece of hardware he sold online for about $4
asciilifeform: moar american l0ltr0n1cs, http://www.courierpostonline.com/story/money/nation-now/2016/06/06/man-sued-30k-over-40-printer-he-sold-craigslist/85478168
asciilifeform: 'Federal agents planted hidden microphones and conducted secret video surveillance at Alameda County’s Rene C. Davidson Courthouse for ten months, despite having no court warrant. The surveillance operation was part of an investigation into alleged bid rigging at foreclosed property auctions where thousands of houses and apartment buildings were sold by banks.'

asciilifeform: perhaps not unrelatedly, cryptome appears to be down.
asciilifeform: one obvious possibility is that he had second thoughts re pushing the tor chumpatron.
asciilifeform: ( nobody executes an asset just for the hell of it. )
asciilifeform: imho the only interesting mystery here is what it was, that was so loathesome, that even appelbaum refused to do it and had sentence of shitburial carried out. ☟︎
asciilifeform: and, what, his shithub key just 'happened' to leak, this piece was planted therein, usgarchive.org just 'happened' to cache the page right before deleted, etc. ?
asciilifeform: lel
asciilifeform: s better known for my abuse of other people — sexually, emotionally, and physically.'
asciilifeform: 'Hey there! My name is Jacob Appelbaum. I'm pretty famous for stealing other people's research and putting my own name on it. I also spend a lot of my time pretending to be a badass hacker, but actually I can only barely code. I enjoy using my social capital, influence, and power in order to manipulate other people into getting what I want. From all that, it's pretty clear that I'm awesome! However, in several communities, I'm perhap ☟︎

asciilifeform bbl, phood
