mircea_popescu: "Another housemate, George, had a vicious temperament and had been in and out of jail many times. He was permanently one parole violation away from ending up back on the inside and had long given up any hope of getting his drivers license back. He had been virile and fecund and had a couple of former wives who had taken out restraining orders against him and several children whom he wasnt allowed to see. George wa
mircea_popescu: s an avid conversationalist and could easily be prompted to hold forth on any number of subjects, although his poor grasp of the facts and numerous delusional convictions invariably caused his narratives to become mired in internal contradictions."
mircea_popescu: this is actually a great orlov piece ; once he abandons his nonsensical hallucinations of "having grasped the big picture" and takes up simple description he's actually quite readable.
mircea_popescu suspects "his acquaintance Tom" is rather autorepresentational, for this reason.
asciilifeform: mircea_popescu: is certainly how i started reading him (initially had good stuff in 'small picture' re su/usa parallel)
mircea_popescu: "Tom either graduated or dropped out from an art school (accounts varied) and could turn out competent artwork if given careful direction, but he disliked being told what to do. Left to his own devices, he indulged in drawing cartoons that featured grotesque caricatures of himself plodding through post-apocalyptic landscapes littered with wrecks of his old cars and wandering shadows of his former girlfriends."
mircea_popescu: "orlov either graduated or dropped out from college, and could turn competent prose if kept on a short leash, but he tended to believe he can actually be in charge of things. left to his own devices, he indulged in antireality boat designs and ridiculous sociopolitical systematization."
asciilifeform: scintillator wins sensitivity in trade for contrast, tho.
asciilifeform: i'ma also try scintillator + ordinary photopaper ( some folx report usable pics via same )
mircea_popescu: asciilifeform if you get "0 penetration" in X time, try with 3x the time and see if it changes anything. if it does, you can then sorta-calc what exposure time you need (see the curves) and then judge if it's safe to expose that long.
asciilifeform thus far can add only that the victim fg still worx..
asciilifeform: has eaten 30m or so, at various energies, largely towards 35k end
asciilifeform too lazy atm to compute approx dose from this, in civilized units
mircea_popescu: anwyay, your other point is also quite sound : can certainly use low pass filter, such as metal mesh or w/e, to filter out lower energy. yes lower instant energy, but if expose for longer in the end get same total energy, more conveniently distributed on spectrum
mircea_popescu: but the overarching thing here : you can't seriously expect to be doing this x ray stuff WITHOUT blowing dust off either h's matrices or the wavefunction.
mircea_popescu: so sit down once and for all and write your equations towards usable form and there you go, math undergirth.
asciilifeform: aha, is what the dentists do. i'ma gild that lily when it turns out to need gilding tho, so far can already clearly distinguish 2 layers of pcb.
asciilifeform: last lulzbit before asciilifeform to bed : the fibrous crud in the photo ? is 1 sheet of printer paper !
mircea_popescu: i think it's unconscionable to be flying this blind/by seat of pants. speaking of that "gilding the lilly", did you even calculate the remanent activity by component for that half hour of exposure ?

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.
asciilifeform: mircea_popescu: i dun have a 10MeV source ( do you ?? ) . tho i suppose one could float the thing on balloon and hope to get lucky with cosmic ray..
asciilifeform: mircea_popescu: they're commercially available , for cost of ~bmw , but i dun want one here lol
asciilifeform: the tube in asciilifeform's instrument maxes out at 35kV @ 0.3mA .
asciilifeform: ( theoretically can do 70kV, per the sticker, but power supply deliberately capped by vendor, so as to get 100% absorption by the cabinet shields and sell as 'contained' or whatever oshaism it was called )
mircea_popescu: in any case, it seems the heathen claim that "it is faster" is only true in a very narrow corner. otherwise--false.
mircea_popescu: these, incidentally, are pretty brutal testing conditions. the average program isn't likely to go 20mn procedure calls deep (witness that almost nobody even knows how to move the stack limit in kernel).
asciilifeform: mircea_popescu: i suspect that diana_coman is the 1st to actually measure, since 1990s (if indeed anyone bothered then)
asciilifeform: why the fuck machine even has an interrupt controller, if idjit programmers run slicer to continuously poll e.g. blocking i/o . it's ridiculous.
asciilifeform: mircea_popescu: unix imho is pretty typical piece of tard 'sleight of hand', where offers illusion that 'you can have 9000 continuous threads'
asciilifeform: good % of the riotous complexity of the sadkernel, once you subtract deviceisms, is the slicer
asciilifeform: ( and the various semaphorisms that it makes necessary )
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: such 'quiet' tubes aint used in medicine, so very little to go on.
asciilifeform: one interesting twist, the machine actually has an ionization gauge below the bottom, under the crosshair. and control panel allows to specify exposure in terms of the gauge output, but in nonsensical 'AEC' arbitrary unit
diana_coman: last time I had to have any sort of idea what that meant, it was iirc having the stamp of higher-stamped stamp-stampers etc
asciilifeform: currently i've nfi where, if indeed at all, 'pro' differs from the public gnat.
asciilifeform: last i looked, didn't turn up a leaked copy anywhere.
diana_coman: my impression was that their upsell was mostly on tools i.e. the IDE whatever-its-name-was
asciilifeform: those come with the opensores gnat tho ( i was never able to get it to run, seems to only work on winblowz and shituntu )
diana_coman: and yes, tools for certification this and that i.e. automated bureaucracy/compliance
asciilifeform: diana_coman: 'compliance tools' aha. but , if not with the standard... then with what.
diana_coman: ah, hm, I thought there was some different version/moar features in the commercial version; anyway, I have to admit I did not really try to get it running as there was no ..need felt for it so far
diana_coman: in truth, they do say "coding standard verification" but I suspect that means whether a piece of code follows whatever convention specified for that project, hm
asciilifeform: bvt: i started with the supposition that it was built for irons where there is no time slicer , but currently nfi whether this is so, or whether was simply a kludge for no particular reason
diana_coman: bvt, my understanding is that zcx said "this case is too complicated to even try to handle and why do you need it anyway, terrorist!"
a111: Logged on 2019-02-23 05:28 mircea_popescu: in any case, the ownership of this entire thing is clearly established, and entirely nobody the fuck else outside of properly authorized republican hands may fucking touch it.
