mircea_popescu: there's a difference between well and wide, for fuck's sake. what is this, intellectual fast fooding
a111: Logged on 2016-09-08 17:31 asciilifeform: the #1 entry is gut-bustingly lulzy to asciilifeform , because i spend ~half year auditing a multilinear-map thing for $rupturefarm, and even was sent to a 'conference' where 'serious cryptographers' did not even blink when someone walked in with a proof that whole thing was crock of shit
mircea_popescu: asciilifeform so why the fuck is "amply agreeable" called "well understood".
mircea_popescu: what the fuck "cryptographic research community", at that ? what's THIS even mean, "cenaclul poetilor judeteni", aka "country poet's club" ?
asciilifeform: i suspect it's exactly like the 'well-understood that you mustn't write own crypto' idjicy.
mircea_popescu: i confess i'm mildly concerned when i don't see these "well understood" shits.
mircea_popescu: me either, tbh. is this also part of the "well understood distinction" ?
asciilifeform: ftr i still dunget what one has to be smoking to use prng ~seeded by N~ as a witness source.
a111: Logged on 2019-01-25 17:21 asciilifeform: meanwhile, in 'holy fuck, i thought we hit rock bottom but then heard a knock from below' lulz, http://www.loper-os.org/pub/mcleod/index.html << 'professor of engineering' tries to argue in favour of old-fashioned , carmichaelizable primality litmus ~instead~ of m-r, on acct of the 'rarity of carmichael #s' .
asciilifeform: ( http://btcbase.org/log/2019-01-25#1889868 << subj, for thread-completeness ) ☝︎
asciilifeform: mircea_popescu: the 'distinction' ? near as i can tell, it's the 'narrative fiction' where 'you can assume that rng works'. recall the earlier entomo-gem where 'why not use fermat litmus, piano will fall on you before you see carmichael num' etc
diana_coman: asciilifeform, authors seem to be with some Uni in London still so probably reachable, yes; but it's still an email first anyway, you know?
diana_coman: http://btcbase.org/log/2019-01-27#1890343 -> a paper with actual content, ha! though I rather doubt the authors' statement that "the need for careful distinction between non-adversarial (or random) and adversarial primality testing is of course well understood in the cryptographic research community." ☝︎

asciilifeform: ( unlike in any pc i've met to date )
asciilifeform: for extra mindfuck : the primary xtal in the bolix ( valpey-fisher vf155 ) is a <1ppm txco. ☟︎
asciilifeform: ( jobs, evidently, didn't spring for the 25ppm xtal.. )
mircea_popescu: shittier oscillator on-board than ye olde ibm-pc
asciilifeform: mircea_popescu: for extra lulz: they drift like hell if denied gsm ( tested with own hands )
mircea_popescu: nowadays, smartphones are within half a second of each other -- jobs fixed paris timekeeping!
mircea_popescu: the original said "The French don't like being famous for their incapacity of being on time ? Let them fix their watches somehow to the same hour, so they quit going about Paris, apparent adults, with half hour's delta among what their watches show. " and i'm willing to attest even as late as LAST DECADE this was a factual state of affairs.
mircea_popescu: meanwhile in other "holy shit, the world has changed!" items : http://trilema.com/2012/slabiti-ma-cu-romali-romales-si-alte-cacaturi/#selection-41.98-41.353
asciilifeform: or, in better-known turdolade, 'The Go programming language (GoLang) 1.10.3 [Goo18] created at Google in 2009 is an open source project including arbitrary-precision arithmetic and cryptographic functionality... ...the pseudorandom number generator used in this primality test is seeded with the tested number n.'
asciilifeform: 'If either LibTomMath or TomsFastMath are selected, the pseudoprimes described in Section 4.9 (see Appendix I) will always be declared prime by the primality test.' << for the innocent : 'tommath' is 1 of those 'independent, not openssl' arithmetrons...
mircea_popescu: "set an env variable" not quite the last word in terms of http://trilema.com/2019/what-is-meant-by-ai/#selection-231.1-231.42 "technololols"
asciilifeform: somewhat high bar; they found trilema, rather than lolcattube etc
mircea_popescu: not a particularly high bar, that.
asciilifeform: evidently there are still meat-people on net, somewhere.
a111: Logged on 2019-01-26 04:57 mircea_popescu: and i'm cordially invited to sponsor his delusion. and if i opt not to, he will... RETRY.
mircea_popescu: there's of course an abundance of http://btcbase.org/log/2019-01-26#1890099 ; but as much as 15 maybe even 20% of the clickers simply do the right thing, go to trilema./ ☝︎
mircea_popescu: asciilifeform well no, but lots of people ~actually look~ at those images and so on.
mircea_popescu: asciilifeform a narrative is a set of interconnected events. as long as no interconnectedness is proposed, it's not a narrative, whether fictitious or factual. so you could say a painting is plastic fiction (while a photography plastic realism). cuz they're not narrative.
mircea_popescu: cheaper than buying another pipe, that's for damn sure.
mircea_popescu: meanwhile in other news, http://trilema.com/2019/trilema-images-no-longer-showing/ rather effectual in that bw usage dropped ~55% directly.
asciilifeform: mircea_popescu: i can't resist to bite : what's 'non-narrative' fiction ?
asciilifeform: diana_coman: coupla of the authors of linked item are at uni of london. think you can get at'em ?
mircea_popescu: exercises in narrative fiction for the fat and the dizzy.
asciilifeform: no amateur can ever hope to equal this 'virtuosity'
mircea_popescu: yeah, right. because there is such a thing as experts, and the femstate spawns them.
mircea_popescu: the fucking gall of these imbecile schmucks, then turning around going "oh, you shouldn't amateur"
asciilifeform: the're 'pros', see , they get 'donations' from microshit etc. and aaapparently ~this~ is whatfor.
asciilifeform: m-r is actually not easy to fuck up, but these folx tried hard, and -- succeeded...
asciilifeform: '...we construct a 1024-bit composite that is guaranteed to be declared prime by the GNU GMP library [Gt18] for anything up to and including 15 rounds of testing (the recommended minimum by GMP). This is as a result of GNU GMP initialising its PRNG to a static state and consequently using bases in its Miller-Rabin testing that depend only on n, the number being tested. We also show how base selection by randomly sampling from a fixed
asciilifeform: ( already fed his N's to mine, it -- unsurprisingly -- does Right Thing )
mircea_popescu: pretty lulzy. you gonna take an article off once you publish to show off both his tests and your results ?
asciilifeform: apparently not only do the derps use prng for generating witness, but they seed it ~with the candidate n~
asciilifeform: ( tldr : d00d generated 'threaded cock for smart arse' composites that break various heathen m-r proggies
asciilifeform: that's gotta be it, i cant think how else.
mircea_popescu: ~nobody left that does work, because nobody left that can work, because nobody left that even knows what work fucking looks like.
mircea_popescu: well, one possible explanation is "the smartphone revolution" : it managed to make say a butler overexpensive through the simple application of "why should i practice being stiff when i could just catpic all day". conceivably, if it managed to reduce the butler population to practical zero, it might've reduced others too.
asciilifeform: printing press , evidently, sent prices for various r&d service through the roof.
asciilifeform: i was similarly astonished by how much the xray people wanted for ~1~ piddling pic
asciilifeform: it is, mind-bogglingly, cheaper than having it done by other hands, even chinese.
phf: i would not have been surprised though..
asciilifeform: micrograph, seems , will prolly have to wait until i get actual microscope here.
phf: asciilifeform: yeap, i've been keeping up with what you've been publishing on the subject. i'm looking forward to your xray results, i mean that's not something i thought would be doable at home, even if a home lab
asciilifeform: ( also possibly of phf interest, the scsi replacement gadget is an a++ win, full docs at http://www.loper-os.org/?p=2943 )
mircea_popescu: the problem with knowledge : as reality scales with the set, knowledge scales with the powerset. not even calling it exponential does it justice.
asciilifeform: ( to go with the http://www.loper-os.org/?p=2913 item )
asciilifeform: phf: on other front entirely, you may find interesting, asciilifeform built an xray machine, some time in coming weeks when i get coupla otherwise free hrs, will take pics of the bolix..
asciilifeform: arguably barrett is the heavy ch., the algo in the given form dun appear anywhere else (e.g. knuth) and so reqs eating the included proof.
phf: i don't understand how anyone can read the logs with one eye, this shit's exponential: i'm behind on ffa, so the recent work on e.g. gcd or miller-rabin is particularly slow going.
mircea_popescu: they were some pretty thick logs, at that.
phf: asciilifeform: up to date
feedbot: http://trilema.com/2019/corydon/ << Trilema -- Corydon
phf: unfortunately i failed to make careful note of various vpatch appearances. there's been some by people other than asciilifeform and diana_coman where the author didn't explicitly request a btcbase upload. so if anyone's explicitly missing a vpatch that they want to be up on btcbase, please leave note with me, privmsg also works
phf: still alive, been keeping up with the logs, but not much else
asciilifeform: will be interesting to test on '9000' koch-generated primes, and see if any... aint
asciilifeform: ^ corrected in re diana_coman thread; and no longer relies on the squaring limit conjecture mentioned earlier.
asciilifeform: ( twice-ex ??!11 )
BingoBoingo: asciilifeform: I'm digging through stuff and apparently Israel doesn't have a strong opinion on Vzla regime change is the US isn't going to have a strong opinion on Syria regime change seems to be the sentiment.
asciilifeform: lol i missed this
BingoBoingo: AHA, but still even when china is shitting out products whether or not people ask quality varies and the US does not appear to recieve the best
asciilifeform: BingoBoingo: was speaking of the variant where you contact manufacturer and upload toolings etc. and pay. rather than konsoomer retail.
BingoBoingo: There's also the excellent Chicom crescent wrench acquired from tienda inglesa which surpases the quality of "crescent" brand crescent wrenches available commercially in USistan
asciilifeform: BingoBoingo: from experience, i know that one can get decent-quality items built in cn if one simply ~pays for it~
BingoBoingo: I have no concrete idea, but the gulf in quality between export grade chinese tooling and domestic chinese tooling is suggestive
BingoBoingo: asciilifeform: Could be China doesn't publish their national security export restricted list?
asciilifeform: https://archive.is/9W8vS << typical subj unit.
asciilifeform doesn't have 1 here, given as never yet perceived any pressing need for such thing
asciilifeform: i cannot resist to throw some petrol in the clocks fire : in the national museum in washingtonistan, i saw a matchbox-sized (1990s) device claiming to be miniaturized cesium clock. why the item aint available for a few bux from middlekingdom, however, remains to me a mystery. ( possibly in fact sham; or possibly some other explanation. )
diana_coman: anyways, I'm not pushing this strongly as "this is how I actually think it was" - as I said previously, I don't think I know enough to have much to say either way
diana_coman: I suppose the argument is that they still were the same thing i.e. that the fineness & precision differences were not so crucial as to make the result essentially something else; I can see it as such and fwiw that'd have been the default way to see it - if not for all the experience of "things that people call X and supposedly is made out of same things as X but different in implementation"
mircea_popescu: much like lenses, really, the difference between a very expensive and a very cheap glass wasn't substantial, both made of polished glass. but much different in implementation, made of complicatedly boiled glass hand polished over months or not.
mircea_popescu: well, for a long time the movements in cheap and expensive clocks were ~same, with mostly a difference of fineness, precision of machining, to distinguish them.
diana_coman: mircea_popescu, perhaps re clocks though I keep thinking that the cheap ones were as clocks as current smartphones are computers
Mocky: by the looks of it, will go approx 4 days without food money before first paycheck, so this was cut pretty close
asciilifeform: ( the problem with doing so, is the 'aging' effect -- the amt of jitter tends to vary as time passes; and the fact of it being a rather expensive means of collecting thermal noise, resistor worx very similarly and costs 1% of what xtal costs )
asciilifeform: incidentally, even txco has high enuff 'jitter' that fairly good rng can and has been built solely from'em.
asciilifeform: i use'em ('txco' being the generic term for subj) in radio.
asciilifeform: mircea_popescu: for thread-completeness - same jp folx (and others) also sell a temp-controlled 'oven' xtal, warrantied to 1 ppm. these draw lotsa current, comparatively, and cost 50x moar, so i did not use in FG ( where the accuracy of the oscillator is solely to put out the expected baud rate, and it dun do any good to make it substantially higher than the receiving machine's )
mircea_popescu: diana_coman if you think about it, that's strictly impossible. they do indeed show delta time each tick, so it's dead reckoning. how the heck would they produce strictly random time.
asciilifeform: i'ma not pollute the log then.
mircea_popescu: (fwiw, i got trilema comments on feedbot 's rss, so it notifies me if/when anyone says something)
a111: Logged on 2017-12-19 18:13 phf: i supper proper presentation of fg schematics in a v-tron is either in the style of the marine chronometer book i have next to me or not at all. "taking first the essentials, c is the escape wheel. the escapement consists of the bar E, carrying the two projections e, e' etc". everything else ought to be handled separately
a111: Logged on 2017-02-17 04:27 phf: re "apprentice as watchmaker" i picked up first edition of The Marine Chronometer by Gould. i would call it "delightful"
mircea_popescu: reformulate there if ye will ?
asciilifeform: mircea_popescu: to reformulate -- in order for redundancy to do anyffin (whether yer dealing with clocks, or RNGs, or any other instrument) the error gotta be ~uncorrelated~ b/w the units
diana_coman: ahaha, I refrained from commenting because I thought "uhm, I have NO idea exactly HOW were those watches broken" but my first thought was that they were likely unpredictably broken i.e. each will show ~random hour rather than "time with x error"
