mircea_popescu: the conclave of cardinals picked the least competent of themselves to sit on throne.
mircea_popescu: "nu-i adevarat (that's not true), romania nu a iesti din aceasta problema (romania didn't exit the matter), romania nu a intrat in cehoslovacia (it never entered) asa ca nu avea de unde sa iasa (had not what to exit)"
asciilifeform: in tito's case , and for that matter kim ir sen's -- 'throne is mine, i won it as partizan commander in the war, took no payola from foreign devils' was tru. but how did the shoemaker get ~his~ throne
mircea_popescu: something. consider actual live events : gorbachev says at the meeting, once they move on past his insistence on having visited the pope as if anyone gave a shit about that "we are all here, who were implicated in the czech affair, except romania, that had exited then".
mircea_popescu: guy never saw himself as much more of a su ally than saudis see themselves us allies i dun suspect.
mircea_popescu: no argument there.
asciilifeform: very easy to 3 instead of 30 when you dun gotta do the rocket, n00kz, etc
mircea_popescu: and he also wasn't impressed with gorbachev;s verbiage as to "disarmament", seeing how romania was spending about 3% of pib on arms in the 85-90 5year plan, whereas ussr had never went under 30% yet.
mircea_popescu: in point of fact, ceausescu refused to sign off on some paper establishing 20 years after the fact that the invasion of czechoslovakia was a mistake. for the fucking obvious reason that he condemned the russians at the time, and according to readily forgotten "consensus" at the time, at no small personal risk.
mircea_popescu: this was reported (via the entirely irrelevant "sources" of talbot, beshloss & co) as "the agitation of stalinist tirant" at warsaw, "unhappy with the us-euro offensive to liquidate communism".
mircea_popescu: he wrote bucharest a general letter about it, proposing to explain what happened on the 4th. ceausescu responded that unless they have a private meeting he's not coming altogether.
mircea_popescu: anyway, there's a pile of disinfo and general crap surrounding the events. as an example : on 2-3 dec gorbachev hung out with bush on a soviet ship. on 4th, there was the wasaw pact meeting. gorbachev was well excited of whatever, the new bulgarian (mladenov, his college pal) and generally the western press coverage.
mircea_popescu: rather.
mircea_popescu: (because of reasons discussed in http://trilema.com/2014/the-problem-of-ideal-social-systems-reprint/ socialisms can't have categorical terms, defined in the normal manner, but must always include the ethical color of all words in the words. so "movement" becomes either provocation (bad) or progres (good) and so following for everything, stalin's cup is named by a different cupword than hitler's self-same identical cup)

mircea_popescu: he was, however, fundamentally brave, in that what he told teh us style "judges" at his "trial" was that he'd much rather be dead.
mircea_popescu: ceausescu was not a gallant sort of brave fellow. during a 1977 miners' revolt (they beat up the commie locals etc) he went there and very much shat it.
mircea_popescu: asciilifeform because furher was a chickenshit ? like any other 90yo ?

mircea_popescu: also fellow misrepresents the failure of the 1989 bucharest meeting. the events flew more or less thus : timisoara rebelled, ceausescu verbally ordered armed repression, on the basis of some discussion, but (most likely deliberately) omitted to actually issue the proper paperwork. the war minister killed himself. ceausescu ordered a meeting organised in bucharest, to announce (in the dead of a bitter winter, without proper he

spyked: anyway, I have much of Scheme in head. I'm looking at tinyscheme mostly to figure out what "subset of r5rs" they've implemented. though I'm expecting tinyscheme subset isn't necessarily the same as tmsr-needed subset.
phf: spyked: i'd also recommend staying away from continuations, they are a cute hack and flow out of some of the classical scheme interpreter designs (i.e. CPS transform), but they are not very useful in production. instead i'd go for a tagbody that gets compiled to a bunch of jmps. in practice tagbody solves 99% of cont problems
spyked is going through Kogge's book at the moment, incidentally. much lower level, but it should help on Lisp internals.
phf: spyked: r5rs and tinyscheme are not the right places to start on the other, non-ada end, i'd recommend looking at lisp in small pieces. you can tease out the theory out of tinyscheme, but it's definitely easier not to get bogged on accidentals if you start from theory

asciilifeform: the interesting imho discovery is that heathen bignumtrons don't win much (or even any!) speed by normalizing the ints being added/subtracted
asciilifeform: http://btcbase.org/log/2017-10-07#1722358 << point was exactly to compare like items. i.e. heathendom does NOT get to 'win' by 'oh hey the hamming weight of exponent is only 2, not 4096, so we only do 4 modexps and not 8192'

phf: i'm trying to figure it out from first principles :) (i haven't had time to look at the recent, i.e. past month, versions yet)
phf: i suspect that ffa's take on expmod is to iterate over every bigit of the exponent, which will have to perform base operations no matter what the numeric size is, but that's a guess.
phf: well, it's conveniently two strategies: closed form solutions and constant iterators. if you don't have a closed form solution, you have to iterate, which you simply do at the upper bound constraint by a data type size. i don't see how theoretically it can be anything else
phf: i guess the point of this exercise is to show that iteration sizes further leak timing information
phf: mircea_popescu: well he either has a constant time algorithm in ffa, in which case if the goal is to compare speed specifically we should be comparing fixtime ffa and fixtime something else. otherwise he has a variable time algorithm running at worst case constant time, in which case the comparison is between base operation speed, which is still going to come out on top
mircea_popescu: phf his point is that if you're going to compare fixtime with something else, better make sure you get a long case in there too.
shinohai: Anyone have the lisp version handy?
mircea_popescu: sbcl is actually the champ ?!
asciilifeform: on heathentron
mod6: and same version of py there too. ok just a sec.
mod6: im gonna try it on the build-donkey box, core2duo/4gb
mod6: <+asciilifeform> out of curiosity, how long the py item takes on mod6's box ? << was just saving... lemme give it a try here. want me to try it on the i5/8gb box ?
mircea_popescu: and in other curiosities, did http://trilema.com/2015/okcupidcom-the-dating-site/#comment-116639 ever come to anything as far anyone knows ?
asciilifeform: out of curiosity, how long the py item takes on mod6's box ?
asciilifeform: in ffa, unlike in the python example, elongating the 0x10001 to full ffawidth will not change the required time.
asciilifeform: phun phakt, this calculation is taken from the gpg autopsies last summer, when asciilifeform was chasing imaginary rng boojum after somebody found a real one
asciilifeform: ^ the 'two second' item, modexp
mod6: mainly, I read through them. because, there's still a lot for me to grok here. and it's easy to fool oneself into groking if you treat it like a blackbox instead of actually reading the code.
asciilifeform: currently i generate them with a pyturd
asciilifeform: i've been holding off on releasing the p-interpreter because there are several quite broad changed in the way that it worx, in the pipeline, and i'd rather folx not get used to the old form.
a111: Logged on 2017-10-02 19:31 asciilifeform: note also that the calling style from early versions will not work, there is no longer a .Z , FZ is not a struct any moar, it is just a word array
asciilifeform: ( it will need a small adjustment in re http://btcbase.org/log/2017-10-02#1719728 but otherwise oughta work )
asciilifeform: mod6: you should have one already, the factorial thing
asciilifeform: mod6: i've been using (unreleased) 'p' as the tester.
mod6: <+asciilifeform> in other puzzlers, http://wotpaste.cascadianhacker.com/pastes/6l4uH/?raw=true << mod6 et al << /me looks
asciilifeform: ( if it isn't obvious from where the error comes : observe the 3 Karatsuba_Term additions. in ordinary K., they walk over the upper half of XYLo ( lower half of result.) but in TopOnly K. we lose XYLo, so that carryolade is lost. )
asciilifeform: now! this procrusted-karatsuba is only used for the barrettron, so theoretically could compensate for that 3 with 3 additional subtractor-muxes. and still win ~4x speedup vs last night's . but this is mega-ugly.
asciilifeform: ^ this 'upper half only' karatsuba works, but the answer is always off by 0 to 3, because the carries from the bottom halves are ( recursively ) lost. somehow gotta be finessed.

mod6: yeah, hard to find the right pace sometimes.
mircea_popescu: today for eg, felt like walk, but didn't feel like climbing 20% inclines, so had girl take me to park. 20km driven to walk 3 or so. imagine the decay.
mod6: mircea_popescu: ah, that's about where i'm at I suppose. i have it in my mind that you do the ba walk nearly daily...
mod6: well, if you walk for 2/3h per day, maybe don't think of them as "shoes". perhaps, "proper foot equipment" or something.
mircea_popescu: mod6 anyway, i'm not a young man anymore. i maybe do 10km a week these days, if that.

mircea_popescu: generally, gift extra used pairs to the help when moving out.
asciilifeform: recently asciilifeform bought a whole case of identical chinesium shits, because they're ~disposable
mod6: certainly a lot better than the $100 shitters.
mircea_popescu: i'd call these medium.
mod6: the pairs i have are this cork that molds to my feet. which feel pretty good day to day. but i walk like 10% of what you do.
mod6: ah, i bet the gel is nice.
mircea_popescu: http://www.anatomicgel.com.br/br/marca.html/ <<< i suppose it could be theoretically called handmade, pushing a point.
mod6: wearing concrete blocks on my feet is for the birds.

mircea_popescu: it'd be easier to ennumerate the converse list
asciilifeform: so asciilifeform is not sold on the Official Truth re item.
asciilifeform: and soon thereafter 'koolaid'
asciilifeform: though some of them iirc turned up with holes in'em

mircea_popescu: only been a day, these days medicare can keep even tom petty alive a day.
asciilifeform: these folx trample one another regularly, there is even a commercial 'holiday' ( 'black friday' ) when they have india-like mass tramplings fighting over misc. retail crud
