mircea_popescu: asciilifeform hey, im not defending random strawman. point was, you have yet to spend 2 hours typing in paths. so no, picking that over latrine is at best figure of speech, and in general simply "discount cost of unlived experience to 0"
asciilifeform: there's 2 possible responses to 'i need to move mountain but haven't the muscle'
mircea_popescu: asciilifeform this is EXACTLY not the case. i am saying "7.62 is sufficient, because it will blow a hole through man, as result of interplay of actual universal constants" and you are saying "yes but 15.2 would be bigger".
mircea_popescu: whereas 2 digit year is based on "we never heard of last century"
asciilifeform: it dun make the people who used 2-digit years in rom code, any less stoopid
mircea_popescu: in exchange you get two things : you get 2x the size of message blocks (an advantage that is actually a disadvantage as now you're using 1kb udp packets which is i expect margionalkly worse than 2 512s) ; and you get a harder rsa (an advantage which is no sort of advantage, the 4096 rsa is already harder than the extant universe)
asciilifeform: at any rate, i'm not sold on the 2^n thing as of yet -- it doesn't seem to win at all, other than (possibly) on readability
mod6: make sense. i personally kinda like the idea that a user can generate a key, that must be 2^n, that is all.
mod6: hmm. so let's say, for instance, that you figure out how to make the 2^n version the same as the 64 width classic version -- performance-wise.
mike_c: _22483.c:835:2: error: expected â before ât
mircea_popescu: the ONE way to constant-mpfhf is to calculate ALL the tree of possibilities, 2^message length items EVERY TIME
mircea_popescu: i opted for 2.
asciilifeform: i bet mircea_popescu had a riot reading russel & whitehead , 'idjits, taking 1500 pgs to prove 1+1=2, which i know to be so'
asciilifeform: mod6: amusingly, if you ~did~ have a big enough and old enough universe to contain primorial(2**4096), you could factor, e.g., mircea_popescu's key, in polynomial time, with plain old gcd
mod6: i thought it was 1*2*3*5*7*11*13 ... all the way up through whatever prime fits into < 4160 bits.
asciilifeform: mod6: P = primorial(N) for some N such that P < 2**4096 .
asciilifeform: !~later tell mod6 http://wotpaste.cascadianhacker.com/pastes/6WPk2/?raw=true << 2^n karatsubas, with same readability as 'classical'
mircea_popescu: 16 is 2 to the power of 4.
ben_vulpes: why is ln(16)/ln(2) so tidily and precisely 4?
asciilifeform: giving X0 of lengh 2, X1 - 1, Y0 - 2, Y1 - 1
asciilifeform: which splits with K of 2 and J of 1
asciilifeform: they exist so that the input:output lengths invariants of subtraction and of kara recurse per se, 1:2, are met
mod6: <+asciilifeform> and incidentally mod6 , is it obvious why this only works if L is restricted to powers of 2 ? << no, i think im missing the entire idea of why this is written this way.
asciilifeform: and incidentally mod6 , is it obvious why this only works if L is restricted to powers of 2 ?
mod6: just wondering if it could be a mechanical push, yet slightly more readable. maybe making 2^n version more grokable?
mod6: asciilifeform: so if you add back in the FZs that were removed in the 2^n version (re-adding in the 50% reduction of temp space that yields no opt.), do we get the ~runtime of the original?
mod6: this might be extra-strength dumb, but... in your new power of 2 version, do you need to inline the Mul & Square of karatsuba?
asciilifeform: mod6: idea with this item, is that L is a power of 2 always. in 'classical' one, L can be anything (e.g. a 192-bit ffa ends up 3*64 on my box, i.e. L=3 )
asciilifeform: so it turns out that imposing 'powers of 2' is NOT a win.
a111: Logged on 2017-08-14 17:57 asciilifeform: if instead of 'mult of 64' we had 'powers of 2', we could dispense with the odd split in karatsuba
mircea_popescu: 2 stage, a 1-200kg booster thing to get it in gross range and a 2-3kg thing to power the last 100 grame spiked ball to the actual satellite
asciilifeform: presumably plan is part of 2-pronged approach where they interfere with ordinary propagation.
mircea_popescu: nobody is ever making non 2^n anyways!
asciilifeform: forcing 2^x = W, x in Z , also simplifies comba
PeterL: (I forgot to increment a variable, so the first number is just 2*(a big exponent of 3) )
asciilifeform: if instead of 'mult of 64' we had 'powers of 2', we could dispense with the odd split in karatsuba ☟︎
asciilifeform: ftr i considered imposing a 'ffa W is power of 2 or fuckyou'
mircea_popescu: and if your key isn't 2^n, further computers will wreak havoc on deployed code by requiring non-dividing Ns.
asciilifeform: 2) replace variable iteration params with fixed, conditional terminations with same
shinohai: Theonly 2 fixes proffered require AT LEAST one week to implement
mircea_popescu: hm... should i lower the pay-for-tits moar ? i mean 2 bitcents is nigh on a hundred bux by now wtf.
mircea_popescu: ben_vulpes and block depth. if you make segwit tx a to me at height 1 and i put it into a normal tx at block 2, i can spend it from block 3 as my bitcoin, the segwitnmess is gone out of it. to steal it from me, one has to rewind all the way to block 1 again. which is possible, but expensive as the chain builds. ☟︎
ben_vulpes: dns is good for you: http://marc.info/?l=git&m=150238802328673&w=2
ben_vulpes: step 1: home orifice. step 2: being useful member of society
mircea_popescu: taking 20MeV source arbitrarily and 2 kev detector, you have roughly speaking 8 and a half halvings at your disposal. if your 1/e distance is 10 meters, that means 40 meters away your detector will still work.
mircea_popescu: basically, a high energy xray will lose 2/3 of its energy every dozen or so meters. whatever's left illuminates the gold (there's no crossing gold, too large barn), and then gets sent back, as gold-xray-pink
asciilifeform: at a metre or 2 yes
trinque: 2, entirely likely the power rangers changed the wallet format
mircea_popescu: asciilifeform re 2 weeks, i readily believe.
a111: 2 results for "bip 44", http://btcbase.org/log-search?q=bip%2044
mircea_popescu: (and in any case, this is also a major improvement over gpg, which realloy only uses 2^16, and worked ok in the field for many years)
mircea_popescu: are you trying to say that since there's only 2^32 possible values for the crc, it then follows that 1 in 4bn will match ?
mircea_popescu: for comparison, a 100 gram tennisball capable of giving a pretty girl a nasty bruise would be going sa 100 km/h and thereby hit for .1 * (100/3.6)^2/2 ~= 40 J over its 0.001 cubic metre space, ie about 40 times more than the jet's "acoustic attack". a 8-gram 9mm round perfectly capable of making a whole new hole hits for 0.008 * 300 ^ 2 / 2 = 360 J over its 20 * 2*4.5*pi = 5.65 * 10^-7 volume, ie about 650`000 times the jet's
asciilifeform: and division is O(N^2).
mircea_popescu: basically, you precompute conveniently chosen powers of 2, and then you get rid of most of the product larger than
a111: 2 results for "kochanski", http://btcbase.org/log-search?q=kochanski
asciilifeform: the unrolled-8word thing is 1 ) less general 2) harder to read with naked eye but 3 ) easier to prove correct
a111: Logged on 2017-08-09 15:58 mircea_popescu: anyway, let it be said that there's nothing wrong with oaep as far as we know, but for the sake of argument a mpfhf based padding scheme would conceivably work like this : 1. given message m, of length l, generate r = random bits, of length l' up to l but not less than 256 bits. 2. compose m' = r + m + c (in that order), where c is l - l` (and its bitness is always same as the bitness of len(m')-256). 3. compose Pm = R + S +
erlehmann: 2. yes, this might be a problem for some, but it never happens to me
erlehmann: 2. look on while almost all of them develop the exactiy same train of thoughts (including fixing make, which is impossible for this kind of program)
mircea_popescu: ok, so then you also send 2, udp sized packets ?
erlehmann: PeterL 1. write grammar 2. ??? 3. never correct invalid input, nuke it from orbit instead
mircea_popescu: anyway, let it be said that there's nothing wrong with oaep as far as we know, but for the sake of argument a mpfhf based padding scheme would conceivably work like this : 1. given message m, of length l, generate r = random bits, of length l' up to l but not less than 256 bits. 2. compose m' = r + m + c (in that order), where c is l - l` (and its bitness is always same as the bitness of len(m')-256). 3. compose Pm = R + S + ☟︎
PeterL: in " n / e^2 bits of entropy ", what are n and e, the key modulus and exponent?
mircea_popescu: and since we're apparently doing rsa likbez : if r used in padding above contributes less than n / e^2 bits of entropy to the final, padded message, coppersmith has a few words to tell you.
mircea_popescu: or how shall i best put it, that's not equality but modulo congruence. whereby 7 = 5 mod 2
mircea_popescu: i have 2.6
edivad: patch is already the newest version (2.7.5-1).
asciilifeform: oh before i fughet, http://btcbase.org/log/2017-08-08#1695461 benchmark is 0.8s on crapple shitbook, and 2.52s on ye olde workhorse x60 ☝︎
asciilifeform: now wouldja believe i spent 3 wks trying to eliminate the if N mod 2 = 0 ... condition in Square_Comba

mircea_popescu: asciilifeform well, they could hire the girl also, and for the 450k you can get a 2 bedroom and rent one. this'll work well as you'll never see each other again
asciilifeform: plox to 1) the seekrit tru picture 2) how mircea_popescu found it ?
asciilifeform: ( i.e. lone d00d, with at least 2-3 day plan horizon; rather than crowd of monkeys )
phf: fwiw i never did experience that whole formulaic writing thing (though i know there were all kinds of other cases of "tattoos for the mind"), my russian/literature/foreign literature classes were brutal, i still have nightmares of cramming poetry last moment, 2-3 hours essay sessions that never seem to end, the three giant Yuri Lotman books
mircea_popescu: 1. phf is walking down the road ; 2. phf perceives something in river ; 3. phf goes to help ; 4.a. phf discovers it was scarecrow, unloads helping module ; 4.b. phf discovers it is muscovy and he's from lvov, unloads helping module ; 4.c phf discovers it's his brother AND CARRIES ON.
BingoBoingo: [1] Thesis, introduce points 1, 2, and 3 [2] Elaborate Point 1 [3] Elaborate Point 2 [4] Elaborate Point 3 [5] Conclusion, i.e. repeat thesis and reiterate points 1, 2, and 3
mircea_popescu: ie, "for its purpose" it has easily > 10mn dpi. but for your purpose, i doubt it has a functional .2 dpi.
phf: i put a 2-person tent in the middle of the room and it made the room suffocating, yes

mircea_popescu: ask the author, or generally any "city planner" what are the wrong assumptions they hid in the nonsense ? they'll look at you like you're from mars. yet... 1. all people = all other people. there's exactly 0 concept of social hierarch. 2. all people == spherical cpus in a vacuum. really bitch, i'll keep track of your stupid grids, and CONNECT ? i'm not fucking connecting lol, wtf do i care where the bus is at.
mircea_popescu: largest tx in 2 is 3854 b ; in 1 1519b
mircea_popescu: anyway, let's see some details. main chain block 168000 is 000000000000099e61ea72015e79632f216fe6cb33d7899acb35b75c8303b763 mined 2012-2-22 at 21:31 ; size 7.1kb

asciilifeform: weigh the 2 kernels, you'll see why.
asciilifeform: but fixed by mp's patch 2.5y ago. and apparently unfixd by bsd
asciilifeform: in other lulz, i DID get netbsd going on http://btcbase.org/log/2017-08-04#1694103 box. but sad part is, it is useless, because 1) no usb 2) nic needs config 3) no way to connect kbd... ☝︎

asciilifeform: 2.7m of what.
BingoBoingo: 2.7 million in Chiraq proper, and 10 million in metro area. Skyscrapers empty, but ghettos full. Chicago has a full "star" mass transit topology, shrinks precieved size of city.
