asciilifeform: put the dressing in blog.ads as constants and be done with it. when erry couple of yrs you feel like twiddling the bg colour or somesuch -- it's a 10sec recompile, wat. ☟︎

Mocky: also, central air units don't feed the chumpatron. room units: huge market constantly turning, repairmen "fixing", "workers" installing, refurbishers

Mocky: they live in constant misery, mostly leaving after a short time

Mocky: in other observations, social pantsuits stand out like a sore thumb here. they can't stomach the "racism" "classism" "mistreatment" "conditions for local women". it's a constant irritant to them, they can't figure out how anyone here sleeps at night being party to such things

mircea_popescu: the pantsuited hilarity herself both knew and said as much, their entire line during elections is "this pays better". and their constant fretful midging on their own "sikrit" comms was all about hiow "apparently people don't care being paid to be stupid nets them slightly more than what they could get on own not being stupid".

mircea_popescu: rmed by Soviet mass culture? Mass-cultural statements are constantly in the process of making themselves true by causing people to experience their common lives in those terms." :

BingoBoingo: My arms and legs manage to tan to darker shades with sun exposure, but my face pretty much constantly stays in a state of more or less accute sunburn regardless of the quantity and frequency of "bloqueador de sol" applied

ave1: diana_coman, I now have a good version of the crc32 bitwise constant time algo, but I ran out of time for today, so eta probably tomorrow.

mircea_popescu: have your own program designed correctly, so your own shitropy management thread ensures your own shitropy calls always return in constant time. YOUR JOB, as a shitropy eater.

asciilifeform: ( there's no point to having the 'Bit1' constant tho )

asciilifeform: ( bonus is that the closed form is not only constant time, but substantially faster on pc, nomoar branch prediction misses ) ☟︎☟︎

asciilifeform: ave1: tables on pc are unconstanttime, on acct of cache

ave1: and for the table lookup, it's the the table access part that's not constant time? (lookup(0) might take different time than loop(255))?

ave1: the div variant could be made to be constant time using the ffa primitives but currently is not.

asciilifeform: ( the table variant is elementarily not constant time on pc )

mircea_popescu: i really don't like this constant process you got in your head going sed -e 's/i don't know/doesn't exist/' everything-i-never-read.txt

asciilifeform: Mocky: the constant in that O(1) unfortunately matters.

Mocky: it's not constant time without asm?

mircea_popescu: asciilifeform after the girls saw http://trilema.com/2015/laile-ou-la-cuisse/ they identified sysco as the tricatel item, it's a constant butt of jokes.

asciilifeform: i dun see how the exact constant makes a practical diff tho

mod6: i mean not constant pain, but pretty bad for the first 2-3 years after that.

asciilifeform: mircea_popescu: the particular physical constant aside, some good % , appears , ~never start~ working

a111: Logged on 2018-09-18 15:31 mircea_popescu: meanwhile at the lulzfarm, "What do you need to know about me? I'm one hell of a kind. Seriously. You might like me or not, but you'll surely not find anyone as annoying/amazing as me. I consider myself a "mystic scientist" because, what is the supernatural world but unknown knowledge? I'm an engineer, a painter, a thinker, a bookworm, a weirdo, a kinkster, a traveler, a constant horny sensualist."

mircea_popescu: asciilifeform it was both -- constantly during the war foodstuffs were eaten, but less and less produced, thus dwindling their supply and increasing their rarity ; while pantsuit "currency" substitutes on paper were not eaten (nor accepted), but more and more produced, thus increasing their supply and destroying their only form of value.

asciilifeform: at least in cement, the empirical fits in a constant. in meat work, it's a wall-sized (and necessarily incomplete) chart of bleargh.

asciilifeform: simply that the answer contains constants that were derived empirically.

BingoBoingo: They gotta constantly A/B test their copywriting

mircea_popescu: " he originally offered his services to the Byzantines, but emperor Constantine XI could not afford his high salary nor did he possess the materials necessary" <<->> http://btcbase.org/log/2018-09-02#1846775 quite fucking EXACTLY. ☝︎

mircea_popescu: asciilifeform specifically via diophantine : if a and b is a natural interval then a*p + b * q (p, q arbitrary constants) will not admit factors ever so often (when they sum to a prime)

a111: 138 results for "constant time", http://btcbase.org/log-search?q=constant%20time

asciilifeform: !#s constant time

mircea_popescu: anyway, the problems were 1. to determine the brachistochrone, and 2. to find a curve such that if any line drawn from a fixed point O cut it in P and Q then OP^n + OQ^n would be constant.

asciilifeform: ( recall, this was the orig thrust behind constant-time rsa )

mircea_popescu: (for comparison, eg https://en.wikipedia.org/wiki/Constantin_Daicoviciu ; this is an actually important fellow, unlike random no-name http://btcbase.org/log/2018-05-05#1810279 ; so it's quite clearly not the romanians being momentarily unlazy) ☝︎

asciilifeform: it's not a constant rate, 7 is the empirical avg., and depends on environmental temp

a111: Logged on 2018-07-09 14:46 phf: i'm remembering when i was in costa rica there was a couple of days when it was raining non stop, and it was "muggy" and everything was constantly wet. visions of tropical diseases from the age of exploration books

mircea_popescu: http://btcbase.org/log/2018-06-26#1829629 << this constant worry at the margins and in the colonies as to "europe suicide". yes, obviously, if ~russia~ let a bunch of rando foreigners in, ~russia~ would disappear. but this is because russia isn't anything, let alone very much. europe is old, and throughout this oldness it "suicided" exactly in the manner described. ☝︎

asciilifeform: mod6: i see it as moar of a bugfix ( a la mircea_popescu's fix of the db locks constant ) rather than troo patch, fwiw

a111: Logged on 2018-06-22 18:03 asciilifeform: in other lulz, nobody noticed this puzzler, so i'ma put it in the l0gz : https://archive.li/i7BRf << cr50 magic rsa keys; the montgomery multiplier etc uses hardcoded constant, 96 word ( i.e. 3072 bit ) for the mults, but the keyblobs are 97 , for some strange reason, in size...

asciilifeform: Mocky: multiply blockheight by 1e6 to get a ceiling for estimated mass ( you will only ever be off by a small constant )

a111: Logged on 2018-06-11 16:18 asciilifeform: one of these was 'reactor control' , with realistic constants, you had to ramp up reactor, control the rods and the sodium pump etc, object was to get max power but avoid meltdown

mircea_popescu: anyway, there's this constant "oh, there's a lot of us, what can you do". i dunno... machine gun the leftovers after extracting all prostitutable girlies ? how about ?

mircea_popescu: eh, england's a shithole to the degree a waspnest better approximates it. they have to constantly tear down old cells to chew into new ones.

asciilifeform: they output ~constant voltage until dead

|\n: good shout, sure i got my miserable excuses, since i'm not media person, i constantly attempt to tell about such things to people who show interest, but the scales are as miserable as my excuses hah

asciilifeform: one of these was 'reactor control' , with realistic constants, you had to ramp up reactor, control the rods and the sodium pump etc, object was to get max power but avoid meltdown ☟︎

asciilifeform: aaaaand hammingweight-independent constanttimeism on arm64 confirmed.

a111: Logged on 2018-05-22 20:05 mircea_popescu: ie, even if the bank welcomed it (which it doesn't because they're trying to do business not participate in la revolucion), you couldn't in good conscience condone a process that constantly results in you processing stolen money. cuz you're not in that fucking business, and if you'd rather be then go work for the ny families or something.

mircea_popescu: now all this withstanding, asciilifeform has a point in the following sense : if you constantly end up with stolen funds, something will ahve to be done about it -- and by you, as a sane fucking person. money transfers don't exist so idle fucktards can sit around on wealth they didn't work for, "oh, i wonder if i should do my homework or read up on carding forums".

a111: Logged on 2018-05-17 21:16 ben_vulpes: sure, but i'm talking about quality of existence here. own place to shit, own food prep area, not having to constantly piss on preferred chairs. it buys security for effects, and calm of mind that i think BingoBoingo underestimates (unless he is a very different animal from what i imagine)

ben_vulpes: you've astonishing will to keep yourself together around the addicts but i worry about the cost of keeping clenched constantly

mircea_popescu: subtle my fucking foot. the ~point~ is that art can not create new forms. which is why the fuck they even did the constant copying of masters to learn arts.

BingoBoingo: Having places to walk to is fine. Having bipedal pollution constantly interupting the journey there...

asciilifeform asciilifeform recalls father's tale re the great bulgarian freighter, the 'pula', that had to be repainted when sent to constanta...

ben_vulpes: constant speed has fundamentally appealing attributes, way lower prop inertia for same power output for one.

ben_vulpes: in other usg idiocies, i recently found a dood who achieved the not-insignificant feat of a constant propspeed belt-drive GAS ENGINE QUADCOPTER butbutbut the rotor pitch variation mechanism RUNS OVER WIFI

asciilifeform: ( i.e. dwarfed by constant factor )

asciilifeform: ( to clarify ftr : a 'dupe mod' ( listed under /dupes ) is a mod that occurs in two or more distinct (hashwise, rather than fpwise, tho distinct fp is also possible on account of variant exponent under constant mod) pgp keyz.

a111: Logged on 2017-12-27 04:33 mircea_popescu: how about a convention whereby all new genesises must contain a manifest.genesis file, which file will be constantly patched on each patchj, no exceptions, by adding a line which reads : "This is patch #x and the codebase hash is blabla".

asciilifeform: i find it hilarious how they carry on pretending that a crypto lib where ~some~ of the functions are (supposedly..) constant-time, is worth half a shit

asciilifeform: 'BN_gcd gets called to check that _e_ and _p-1_ are relatively prime. This function is not constant time, and leaks critical GCD state leading to information on _p_.' and a few moar.

asciilifeform: in other lullies, https://eprint.iacr.org/2018/367 >> 'Most of OpenSSL's constant-time code paths are driven by cryptosystem implementations enabling a dedicated flag at runtime. This process is perilous, with several examples emerging in the past few years of the flag either not being set or software defects directly mishandling the flag...' 'granularity issues due to word-size operands to the GCD function' etc

asciilifeform: just . don't. fucking. swap. to. them. and don't winblowz/crapple/whatever shituntus insist on constantly massaging the drive for no reason.

ben_vulpes: probably same programs that harp on quantum decryption and steadfastly ignore their own failures to produce constanttime encryptulators.

zx2c4: mircea_popescu: and i think having that kind of thing always on -- constant chattiness -- would be a security step backwards, since it'd give up stealthiness. but of course if you still wanted it for a special use case, there's nothing in wireguard preventing you from having it pretty easily

mircea_popescu: Darwin_Fish, anyway, theology is the study of divinity as a theoretical possibility ; religion is the study of historical human practice. the catholics resolve this problem by claiming (falsely) that they were specifically promised god will preserve their religion in theology. this claim has all the strength of their claim constantine deeded them the world.

hanbot: i get that most irc channels and chat venues in general encourage this constant stream of self-evident, redundant, low-content chatter, but #trilema doesn't come close to most. there are people trying to communicate and get shit done here, and while you and your titprovisioning are quite welcome, the noise overhead is not.

zx2c4: mircea_popescu: asciilifeform: http://btcbase.org/log/2018-04-12#1797528 http://btcbase.org/log/2018-04-12#1797506 -- in case you're interested in the ecc stuff more, the formally verified fiat and hacl implementations are not the only ones we have. we also have constant time accelerated x86 adx and bmi2 implementations https://git.zx2c4.com/WireGuard/tree/src/crypto/curve25519-x86_64.h and also constant time accelerated arm neon implementations ☝︎☝︎

mircea_popescu: depends. performance on ACTUAL constanttime items is not so good.

mircea_popescu: zx2c4 is this constant time ecc implementation on display somewhere btw ? i don't think i ever saw one before.

asciilifeform: it is demonstrably not constant time, on several popular machines, we went over this

zx2c4: the ecc is constant time. but anyway the transport layer doesnt use any ecc

asciilifeform: zx2c4: the distinguishability of keepalives also makes it considerably easier to carry out timing attack on your nonconstanttime ecc engine

asciilifeform: i'm curious, for instance, whether any of the cryptographers observed that the arithmetical routines behind your ecc are not in fact constant time on e.g. arm.

asciilifeform: zx2c4: i've spent the past ~2yrs writing a properly constant-time arithmetic lib. it is being slowly published. ( see earlier link to my www )

zx2c4: asciilifeform: i haven't been able to observe any non-constant time multiplications on intel in that code

asciilifeform: btw zx2c4 , i must regret to inform you that the code you linked, is in fact NOT constant-time on several common architectures, because it makes use of machine MUL instruction ( gcc will compile a nonconstant-operanded '*' to e.g. IMUL on x86 )

zx2c4: by only using a limited subset of constructs which are known to be constant time

zx2c4: also, constant time

ckanggirl: one tried and it just looked like his face was constantly dirty lol, i made him shave it

mircea_popescu: asciilifeform you understand how the usg uroborus goes ? constant eating its own tail : 1. have "idea" ; 2. get "finance" for idea ; 3. implement "idea" to "grow big" because "monetize later" ; 4. someone else has "same idea" does it cheaper ; 5. collects finance to "grow big" because "money later" and so on

mircea_popescu: this is a source of constant surprise, consider all the time phf sunk into chasing unicode obscura on his logger.

mircea_popescu: imo brits are the dumbest of animals, and for two reasons : the constant rape the muslims put them through, and the constant rape the real estatists put them through.

douchebag: No, I constantly put effort towards learning more and improving my skills as well as my self.

asciilifeform: in other quasi-noose, if n is p*q, and 4p-1 = d*b^2, where b is integer and d is in {3,11,19,43,67,163}, n is factorable in polynomial time (with modest constant!)

mircea_popescu: aaand in today;s random trilemalulz, "Meantime the camp was filling up with people, and there was a constantly growing excitement about our Humboldt altcoin. We fell victims to the epidemic and strained every nerve to acquire more "coins." We prospected and took up new chains, put "notices" on them and gave them grandiloquent names. We traded some of our "coins" for "coins" in other people's chains. In a little while we owned

asciilifeform: ave1: the reason i wrote my mechanism as seen in ch8, is not only that it was the simplest physically possible that i could think of , but that i regard any invocation of randomola where i cannot substitute a known value for testing, as a serious problem -- how is one to know that the proggy actually does what is claimed with the randomola ? rather than, e.g., 'lose' some (or all of it) along the way and take a constant as the 'rando
