mircea_popescu: diana_coman, you know, reading your boys' things, the most striking lulz is the creeping in the usian socialist republic of the traditions of the romanian socialist republic. do you recall how utterly infuriating for the general population it was, in the 80s, the constant need to have all social arrangements dependent on the very flimsy supply arrangements of the bankrupt & dysfunctional state ?

billymg: http://logs.ossasepia.com/log/trilema/2020-01-27#1957376 << ah crap, sorry i missed this earlier. they are more like constants (for adjusting e.g. whether you want decimal or roman numeral footnote identifiers) that were stored in the db because the average wordpress luser can't be trusted to edit a few variables in a php file and needs checkboxes he can click instead

billymg: http://logs.ossasepia.com/log/trilema/2020-01-27#1957403 << and this is the one, in mp-wp, that currently includes code that actively writes options to db. i was proposing to remove any remnants of this completely and only leave what would essentially be some constants at the top of the file (though it sounds like even predefining some of these values at the top of the file is unnecessary and can be removed as well

billymg: her only "education" to this point has been the usg school/college system, which i'm constantly working to undo

mircea_popescu: sorry for the constant complaints borne out of user error, plox don't take it to heart.

mircea_popescu: it's a constant "um, roxana... who the fuck's roxana. oh." "monica ?" "ah" and so on.

BingoBoingo: nicoleci: I've long ago settled on XFCE as my balance between "sometime point and click offload pressure on my brainbox" versus "I don't want to subject myself to engineers constantly breaking everything"

ossabot: Logged on 2019-11-09 02:56:16 ave1: which was hard for the lam part, but seems impossible for the p part for now. Because (a) php is an interface to almost all libraries on the system and (b) the configure scripts constantly find gcc based libs on the system plus (c) it uses gnu clib specific tricks.

mp_en_viaje: otherwise, since ~literally~ 100% of the crap on the "free" and "open" anglo internet is ~LITERAL~ fucking restatement of the ~~~EXACT FUCKING SAME~~~ five line passage from harvard's 1999 offering of doubleplusgood truth&realities (if you don't count a very carefully expurgated version on "marxists.org" -- lulzily, "dog" appears exactly once ; "vulture" not at

asciilifeform: ( concretely : 4 'dulap'-style units , while (w/ mp_en_viaje-corrected set of constants) putting op +240 in +ev, in fact exhausts the energy allotment (not overruns, but leaves room only for rk plant.) and there already were requested, counting everyone who answered, tentatively 4 dulap's worth . (5 if counting shared-box) . )

asciilifeform wonders if he's thinking about this backwards, and oughta instead model the upper half of (expanded) tower as a separate numeric system, w/ same constants but Te == 200.

BingoBoingo: I suspect Maxi boy is under strict orders not to contact me further in light of the liability he constantly generates, provided he is still employed by Latecho.

BingoBoingo: asciilifeform: With the scrapyard thing you probably want to have the list of what in particular interests you, lest you end up receiving constant junk offers.

mp_en_viaje: sounds easy enough at the entrance gate ; but once inside it becomes obvious that where can't live, can't live. my constant "either help me build something, help the idiots be idiots, or be sad in a corner -- there's no other option" is, similarily, insistently perceived as so much empty bravado at the gate. but, in reality, as time goes by...

asciilifeform: mp_en_viaje: i will be speaking in person to proprietor to help fill in all of the constants for numerics ( in particular, the cost of additional amperage, when required ; and the stability of the (suspiciously low) price , in particular re desirability of locking it in through advanced payment . )

asciilifeform: mp_en_viaje, diana_coman : i'ma have to re-do the whole numeric orchestra, and write proper summary, w/ rationally-founded constants and at length. will need , potentially, entire day. ( still guarantee cost less than piz, however, for analogous machines. )

asciilifeform considered 'what if priced FG-style, as fixed constant in btc?' but this would prolly result in outrageous overprice that few would be willing to eat.

ossabot: Logged on 2019-10-13 06:42:11 mp_en_viaje: in other lulz, i suspect about half of the ru ip space is "soft" banned in germany, constant "inexplciable" service interruptions etc. can't eg load archive.is most of the time, and so on

BingoBoingo: I suspect the dtng resurrection is the way to do image pasting, seeing how everyone else constantly resurrects the broken less functional takes on the chan format

asciilifeform: it is interesting, irc protocol asks that pingism follow form 'PING foo' 'PONG foo' . but their foo seems to be a constant.

asciilifeform: the 1 exception being 'apu1' , but is sewn from 2013 'g-series' that amd is constantly threatening to 'end of life'

BingoBoingo: The folks I knew who went pilot did the lessons. The one I talked to more was constantly stressed, because only so many of the folks taking lessons and flying prop planes from Murphysboro, Illinois to Pinckneyville, Illinois and back would get the opportunity for further instuction on flying things that would earn them a bunk and meals.

asciilifeform: but i strongly suspect that 'ada logtron' will consist mostly of non-humanreadable hex constants , and the pg glue will be eating null-termed c strings , and generally the result will not be a thing you 'would fly in it? i wouldn't walk under it!'(tm)(r)(h. hughes)

asciilifeform: and would not even be able to "<a>" + whatever + "</a>" etc, i.e. can't use the existing sugar for string constants at all

asciilifeform: http://logs.nosuchlabs.com/log/trilema/2019-08-09#1926712 << it is entirely possible to have sane ~back end~ on which you, e.g., write in a lisp-flavoured skin when mangling trees, and a fortran-flavoured skin when want to run in constant space/time with fine control of flow; the bolix people -- had. in fact, arguably all machines have (presently piss-poor) incarnation of this concept, it is... the machine arch itself.

asciilifeform: nao in re mechanicals -- bot is written from 0 using bare sockets. www end and bot eat a common config, there are nomoar 'magic' constants in the proggy. so it will be pretty simple to set up mirrors after genesis, if anyone is up to it

asciilifeform: ftr asciilifeform is sewing a constant-time keccak so that peh can rsa in battlefield. is someone gonna do this in my place, so i can write www log ??

asciilifeform: ( on pc, in addition to 'unix leaky' and other boobytraps, also gotta contend with not knowing what the fuck the cpu does internally in re constant-time )

asciilifeform: PeterL: tricky bit is, you have nfi what is the constant until the van shows up.

spyked: granted, I never set out to publish a logger www, but given the constant need and lack, I'll add it to my list

mp_en_viaje: what the fujck will i do with this disaster, the constant problem of "fuck me, now i can't find it" is one part ; the other part's that well... even when i think i know exactly what i want, an ever growing possibility is that in fact i don't, there's a better option i'm just not thinking of.

mp_en_viaje: ego bricks around the house. this doesn't make them some kind of magic gurus, nor does it make your own understanding of the systems and processes involved somehow inconsequential. why does it constantly have to come back to this purely psychogenic, oh, nobody reads, oh, nobody can sit down a kernel, whatever the hell ? it's just not a way to go about things, nobody's achievement is diminishing your own nor does your achievement necessarily require

bvt: now, sse could theoretically help, but there is a question of whether sse operations are constant time (in each generation of intel cpus)

asciilifeform: ( re upstack, note that primegen.peh can be written without any long constants, i.e. generate primorial at warmup. this simply costs a coupla extra min. )

asciilifeform: http://btcbase.org/log/2019-06-06#1917441 << this is moar or less asciilifeform's exact position. mircea_popescu i rec. to glance at ch18, it has good picture of this (i.e. reader is not offered 'use this tape', is offered 'here's how to bake a primegen' ; instead of 'here's magic constant', given 'here's how it is made' etc ) ☝︎

asciilifeform: ... so in principle if you wanted to litmus against the 1st 1386 primes, in a 2048bit primegen , you will need 8 gcd litmusen, each with a separate 2048b constant.

asciilifeform: summary of colours: O(bitness) (i.e. the cheapest) ops are marked in green; super-linear but subquadratic ops (e.g. *, S) -- brown; the most expensive ops (e.g. MX), and ones with potentially 'infinite' cost (e.g. ?) , red; ops which affect control flow ( : , various Q ) are inverted-red ; ops which affect registers -- purple; constants - black; function defs/invocations -- blue/reverseblue respectively. errything else i think self-e

diana_coman: asciilifeform: for one thing you already have skills he doesn't yet seem to have and for the other thing you constantly say it yourself that at times there is no juice left for ffa /similar.

asciilifeform: in other heathen lulz, o(n log n) int mul. ( spoiler: with gigantic constant, a la aks ) ☝︎

mp_en_viaje is full up on "so and so tax was forever banned with terrible curse. in 1806. in 1814, ruler paid patriarch in constantinople to raise curse, reinstated tax"

whaack: gringo friendly atmosphere means ticos who know english and are constantly trying to ease your stay by parting you with your cash, more or less

asciilifeform believer in 'proggy may not be the spec' dictum. in the arithmetic chs, however, there is no spec beyond e.g. 'multiply these two numbers in constant spacetime', which has simple unambiguous meaning.

mp_en_viaje: / sociopath" nature. they stem from his own fucktarded assumptions ; not sharing in those assumptions means not paying their (very burdensome) cost, means being able to engage in "magic" feats that are "impossible".

mp_en_viaje: hey, i constantly end up with this problem, and my answer is always the same : get satellite dwelling, then get larger main, then end up getting satellite again, and so on.

mp_en_viaje: item was the basis of the guild revolution in europe (because yes, ottoman contact, incl "fall" of constantinople -- more properly, RISING of ~) was very highly +ev for the yurpeans, culturally.

asciilifeform: OriansJ: lotsa folx over the years landed in the logs, and thought 'these people sit and philosophize and what'. but plenty of examples of working mechanism , if yer interested to study. http://www.loper-os.org/?cat=49 for instance is a just-short-of-done constant-time 0-dependency cryptoarithmetizer.

OriansJ: an 8bit immediate can be very useful for dense code and it would fit most bootstrapping constants if it is signed; support for 16, 32 and up immediates makes supporting compilers for C/Ada easier to write but it isn't a real issue if you have support for IP relative loads of 32bit and up values

BingoBoingo: Well, they tend to build on each other. The Linux (dubbed Cuntoo) is to escape all of the distributions constantly changing the base and tools.

asciilifeform: granted the jp item not as efficient, if you recall it's the pellet thing , built for constant output

asciilifeform: nao the q becomes, you later look at what came out of the wire. is it possible to conceive of a 'rng test' that the output would not (for particular p , taken as constant) fail ?

asciilifeform: ( the latter not used for any of the published tests, but to simply gauge the effect of 'modern' x86isms . fwiw does have constant-time mul etc )

diana_coman: "Dudes are out here going to the gym to only work out their arms and chest and constantly skip everything below their torso." aahaha

asciilifeform: ( in fact ada per se has a fascism knob that, if set, prevents early return from subroutines . i have not thus far used, cuz in ffa per se this is already the case, nuffin gets to terminate early when 'constant time' algo )

chonkin: "Sexual harrassment" was supposed to be a recognition of constant, perpetual ongoing sexual imposition into conversation that created a constant atmosphere of toxicity for female employees.

asciilifeform: the knobs still on conveyor are -- subroutines; hash ; constant-time table lookups. that's it.

asciilifeform: i'd like to request 5min of mircea_popescu wearing papal regalia . ch17 ffa , as perhaps was clear from http://btcbase.org/log/2019-03-14#1902386 , has a control-transfer stack ( for loops & subroutines . ) it, like errything else, is nonheapistic, therefore has a fixed size. currently set to 256. this constant gotta be nailed down. is 256 enuff? too small? too big ? ☝︎

asciilifeform: 'but asciilifeform , if you want lobster, you gotta build a $9000b fishing fleet' 'mno, here's 1 from your own dryer lint trap, and it can bend xrays and modexp in constant time, naowat'

mircea_popescu: it is a constant complaint of the actual females, this. and one i always agree with -- when they bring it. because yes, there's nothing fundamentally female about the pig.

asciilifeform: constanttimeized stein's o(n^2) gcd ( http://www.loper-os.org/?p=2963 ) is not only imho fast enuff (even a magical 100fold speedup in it, would not affect speed of rsa key gen measurably , consider above ) but fits-in-head and has no error terms.

asciilifeform: in re single-shot gcd, you either ~look at the bits~ , and that's lehmer's (not constant-time-able) method, or you do not, and that's stein's or the division-powered one, and i suspect it can be proven that yer stuck with quadratic runtime if you dun look at the bits.

asciilifeform: bvt: from surface look, loox like lulzy piece, e.g. 'The algorithm is not constant-time as shown but can be made constant-time with low overhead'

bvt: asciilifeform: https://gcd.cr.yp.to/papers.html -- rather new constant time gcd from djb. i did not look at it closely so can't say if it's anything good or belong to the kunstkammer

asciilifeform: bvt: the only new instrs that seem to be even theoretically of use, are 'mulx' and 'adcx' -- but i dun have any iron that supports these atm, and cannot even begin to say whether constant time etc

asciilifeform ~still~ frustratingly wedged with mircea_popescu's tube puzzle , turns out the 'S' constant for 35kV aint published anywhere, incl. the tube vendor ! and no info published re how to determine it from principles, seems like it gotta be measured by hand.

asciilifeform went to compute mircea_popescu's q, 'just how much did it eat', apparently it's a bitch : absorption constant varies by chip, and in heavy industry folx mostly gave up , they stick dosimetric film underneath the board. i'ma get an upper bound tho, it's important q when we do the bitflip thing.

a111: Logged on 2019-02-16 09:44 ave1: diana_coman, in system-linux-*.ads (in gcc/ada directory) you'll find the line: ZCX_By_Default : constant Boolean := False;

asciilifeform: mircea_popescu: this is why i like 'run 9000 shots, and discard outliers' (granted this only applies when the item is expected to go in constant time, goes without saying)

mircea_popescu: and so on, this constant up AND DOWN the tree calling paradigm recreates c++, java and usg necessarily.

mircea_popescu: and should we discover that, suddenly all the early, romantic era preaching about inflation being bad ~per se~ will need to somehow be adjusted into "inflation bad because a) market-impredictable and b) government-arbitrary", and a lot of pointing out that "systems with preknown and immutable inflation are exactly equivalent to systems with no inflation", "because in functional analysis all constants are equally C" or somesuc

asciilifeform: if you ever end up putting it on a cray, you change the constant knob & rebuild, is all

asciilifeform: re reversed -- iirc in prev thread , went mircea_popescu : 'justify this constant logically!' a: 'not errything can be justified, sometimes yer stuck using guts!'

asciilifeform: in other lullies, https://duckduckgo.com/?q=miller+rabin+constant+time << seems like we're the only folx who ever showed detectable symptom of giving a shit..

asciilifeform: iirc we ~did~ have a thread where 'why didn't they make a chronometer that can be stuffed up arse, for constant temp' tho.

asciilifeform: diana_coman: 'nothing to do' is because it's a legit witness! algo returns 'prime'. ( and in non-constanttime incarnations, this is the ideal, shortcut case in fact )

a111: Logged on 2019-01-09 00:19 asciilifeform: in other noose, constant-time stein-gcd aint so bad, 1msec (2048bit operands) , 6msec (4096bit) , 21msec (8192bit), 81msec (16384bit)

a111: Logged on 2019-01-11 17:30 asciilifeform: btw per asciilifeform's chalkboard, the physical cost of constanttime m-r is ~equal to that of (2 modexps of the given width) x (number of witnesses) .

asciilifeform: the rule will include a constant, and that constant is at most as big as the prime itself

asciilifeform: koch's turd, despite being implemented in c, with no bounds checks, actually loses to ch14 ffa , for inputs of same ~width~ -- despite fact that he doesn't constanttime and thereby gets to skip massive work

asciilifeform: ( this is not a contradiction in terms, it is possible to implement whole thing, with same constant-time algos, by hand asm )
