asciilifeform: now see ~some~ people, odin himself made'em to prop up neutron reflector with dainty little fingers.
mircea_popescu: meanwhile on the other side, "About me I love the X Files and Criminal Minds. I'm studying Cosmetology right now but next semester I am transferring to Psychology. "
mircea_popescu: there's space in the middle.
asciilifeform: as i understand, usg dept. of wunderwaffen hasn't given'em robo-cranes yet, at that pt
mircea_popescu: by the time your evening's entertainment is screwdriver-juggling neutron reflectors, you've got some pretty serious pretentious issues going. i mean aestheticism is one thing, but by the time that's all that's left...
asciilifeform was thinking of this just this morning, while varnishing the 50kv cabling on the xray box
asciilifeform: i dun consider slotin et al to be shining examples to follow, but will also point out , that errybody dies eventually, and personally would rather chance to eat 100kV than to die of boredom sitting in a chair kanzure-style.
asciilifeform: mircea_popescu: i was cured of this by chem instructor, who showed palm where glass pipe went clean through it when he was a lad
mircea_popescu: BUT I WAS THRITEEN
mircea_popescu: yeah... you know i used to do the old thumb-stopper thing... until i noticed i got spots.
asciilifeform: ( i suspect that current-day 'millenial' derps would shit their pants if they saw folx actually at work and the things that are done even nao )
asciilifeform: even as late as '90s lab folx had to be beaten with a stick to get'em to stop mouth-pipetting, etc
mircea_popescu: well then. monkey was monkying about, gimme a break.
mircea_popescu: you telling me slotin was a sort of curie jr, had "no idea what could occur" ?
asciilifeform: but some folx, when considering 'hmm, taste, or go home' will taste.
asciilifeform: well arrhenius or who it was, didn't ~have~ to taste his reaction products either
mircea_popescu: while the former is actually true, the latter doesn't follow, it's not like he had to use the beryl for a soup bowl.
a111: Logged on 2018-09-11 01:22 asciilifeform: incidentally much noise was made re the elaborate calculations of early nukes, but good chunk of the design params ~also~ only were accessible empirically. hence the slotin incident.
asciilifeform: problem is the 'xray hygiene' thing, outlined by mircea_popescu in earlier thread
asciilifeform: mircea_popescu: they do.
mircea_popescu: i don't get why they can't simply use a mirror / scintillator / something.
asciilifeform: i haven't seen with own eyes tho ( and would rather not ) the biznis-end of that.
mircea_popescu: possibly they tried the dating market.
asciilifeform: on a few occasions i had to go to where it was done. power supply cable as thick as my thigh.
asciilifeform: ( btw does mircea_popescu have a theory re why people become crystallographers ? it's almost 100% young chix, and they -- even with modern shielding and safety derpisms -- never live particularly long. multi-MeV xray cannon in yer face... )
asciilifeform: sorta what keeps the old-fashioned crystallography people in biz.
asciilifeform: ( on top of this, the actual meat being modelled is not a rigid object, it has substantially variant geometry depending on temperature and properties of medium, e.g. ph )
asciilifeform: problem is that you want flex in the bonds ( to model strain, van der waals, etc ) but you dun want it to sag.
asciilifeform: mircea_popescu: watson & co tried this.
mircea_popescu: let all the bright minds monkey swing from the fucking thing until they fall over.
mircea_popescu: i tell you honestly, if i ran a lab where such a compound was seriously important, i'd spend the 100k or w/e it is to have a model welded out of steel balls and rods, and place it in the lab gym.
asciilifeform: i had a 30k$ sgi 3d viewer thing, worked ok ( 1 part 50kg crt, other part went on yer head. ) point is that nao you can get ~same thing for 100. not that there's much in the way of people who are still doing any of this afaik. ☟︎
asciilifeform: ( consider, grunting through each atom, serially )
asciilifeform: von neumann comp spectacularly retarded for the app
asciilifeform: i used to do this for a living, tho. ( and no it aint a great biz to be in, the models just barely work )
mircea_popescu: hm. did that sentence pass parser ?
mircea_popescu: your head will fall out through your arsehole if you attempt to meaningfully interact with something as large as to make that thing collapse into degenerate matter through a "3d visor" color interferer thingee.
asciilifeform: there's a practical limit to anyffin.
asciilifeform: mno. when you have 10,000 sticks, thing sags under gravity, in very 'unphysical' way re the item being modelled.
mircea_popescu: asciilifeform no, see, what you call "unwieldy" is the very quality of the item in question. that is it's true value.
mircea_popescu: turns out there's NOT THAT MANY possible atomic states.
asciilifeform: mircea_popescu: these are great, but when yer doing a protein gets expensive and bit unwieldy ( picture room-sized stick model )
mircea_popescu: afaik to this day unbeatable modeller.
asciilifeform as a boy built the classic toy boat from tin can and soldered ballpoint pen tune (the iron kind), add a camp stove pellet and a++ 'pulse jet'
mircea_popescu: asciilifeform at the same time, we had very good quality 3d chemistry modeller. it consisted of a bunch of sacks, with colored spheres with holes correctly planarly inclined, and plastic sticks.
mircea_popescu: at least the french socialists entirely dedicated themselves to "aesthetics" ie masturbation, rather than "science" and "engineering"
mircea_popescu: in fact, that publication enduringly shook my confidence in german intelligence. included ALL SORTS of utterly retarded shit -- say a "boat" consisting of a piece of paper with a cut inside, you pour oil there and it "propels" it
a111: Logged on 2017-07-20 19:52 asciilifeform: because unlearns faster than learns.
asciilifeform: re nn in general -- i vaguely suspect that a quality rng might actually cure the http://btcbase.org/log/2017-07-20#1687624 problem. but again i dun have any pigs, so haven't had occasion to try. ☝︎
mircea_popescu: spoiler : they sucked.)
mircea_popescu: (frosi, teh magazine of teh ddr's own pionierorganisation iirc, included a pair in one of the editions i got. i even played with them.
asciilifeform: ( they offer a 50 $ dev kit, compleete with cd fulla winblowz shitware )
asciilifeform: i simply can't bring myself to buy any to test, i dun have any pigs that need autoclassifying
mircea_popescu: was all the rage when i was in school. alongside the period "GREAT DISCOVERY" of "3d glasses".
asciilifeform: mircea_popescu: y'know, neural net, the thing that classifies pig as 'porn' etc. i'm even willing to believe that the chip worx to spec. not magic by any means, 1970s tech sitting on modern ic
a111: Logged on 2019-01-20 17:20 mircea_popescu: apparently 200 reqs ~per 100ms~ (that's how long it takes to complete one) is not enough to bring it down.
a111: Logged on 2019-01-20 19:59 asciilifeform: a fast rsatron is important mainly in light of fast rejection of crapola sent by enemy, rather than for payload per se.
mircea_popescu: http://btcbase.org/log/2019-01-20#1888637 << this is very precisely on point, hence why http://btcbase.org/log/2019-01-20#1888551 is such win and so on. ☝︎☝︎
a111: Logged on 2019-01-20 19:47 bvt: you can't verify output of 'write 4096 adds' by hand, though
asciilifeform: supposedly fits trainable nn, coupla 10k units worth.
asciilifeform: intel for instance sells 1 , for about 20bux in qty. what is actually on the die , i have nfi, and it only worx with their oddball closed compiler thing.
mircea_popescu: w/e, perhaps i do not see teh future.
asciilifeform: ( and again will note, i haven't tried the various irons, may well be snake oils. )
mircea_popescu: "want". so far that thing only keeps "researchers" mortgages paid.
asciilifeform: nah see, they want face reader in pnoje, toilet, ballpoint pen, etc. where (despite mighty effort) x86 dun go.
mircea_popescu: asciilifeform only "revived" as a money sucker, afaik deployments still on off the shelf micro
mircea_popescu: even the http://trilema.com/2016/give-computers-the-vote-theyre-cheaper-than-women-even/ hollywood production moved to x86.
asciilifeform: (e.g. the recent fad for 'face recognizer' even revived 1980s item, neural network processor. i haven't personally tried'em for anyffin , of yet )
asciilifeform: mircea_popescu: it's alive, in a sense (various image processing junk) but not sumthing you'd want anyffin to do with i suspect
a111: Logged on 2019-01-20 19:12 bvt: are such machines even build these days? i.e. for dsp, or other use-cases?
mircea_popescu: http://btcbase.org/log/2019-01-20#1888589 << specialist machine market really died in the 90s, and was buried slowly hence. ☝︎
asciilifeform: the algo for this, i described coupla yrs ago here.
asciilifeform: this gives the 'write block on disk only 1nce' behaviour.
asciilifeform: *experimental trb, err
asciilifeform: in asciilifeform's o(1) tx indexer ( will be welded to an experimental bdb once i get the mmap thing resolved ) there's a 2-level storage -- a 'write-once' o(1) index for blox of age N ( N can be 100-500 in practice ), and a much smaller rewritable one kept strictly in ram ( for 'recent' blox, where the longest chain is potentially movable ) ☟︎
asciilifeform: (tho, will add, the retarded design of bdb, gives early death on ssd. in sane indexer there is never any reason to touch any single block moar than once )
mircea_popescu: in principle, for as long as that's not run out, the disk won't lose sectors. but then again, a definitive answer to this turns into debug-ssd-fw+kernel, which...
mircea_popescu: afaik ssd realloc counter starts turning ~the day they're deployed.
asciilifeform concurs that there's 0 point in debug of bdb, it's medicine for a corpse
asciilifeform: i'd look at the realloc counter on the disk, betcha it's started to turn.
mircea_popescu: instrumentation to hunt for this is by now in the vein of "debug bdb". which im not particularly inclined to do, marked for complete removal anyway.
asciilifeform: ( there -- found this twice, to date. )
asciilifeform: mircea_popescu: that's the interesting imho part. ftr i have yet to witness a corrupted-but-openable bdb on machine other than where ssd was found to have rotted.
mircea_popescu: asciilifeform disk afaik fine ; probably bdb itself shat it at some prior point, tho atm dunno a mechanism.
asciilifeform: a fast rsatron is important mainly in light of fast rejection of crapola sent by enemy, rather than for payload per se. ☟︎
asciilifeform: ( a single FG , recall, yields ~7kB/s at room temp )
asciilifeform: i'll add , for completeness of thread, that if yer ~sending~, rather than receiving, rsa packets, your bottleneck will be ~rng~ long before it could ever be the arithmetron per se
asciilifeform: the inner loop or 2, tho, definitely can.
bvt: this is true, rigth.
asciilifeform: there's an obvious limit to what you can unroll and still fit in any plausible cache tho.
asciilifeform: and besides, the wall wouldn't even have that many bricks -- on a 64bit bus, a 4096-bit addition is 64 instructions long
asciilifeform: it's no moar complicated than to count bricks in a wall.
asciilifeform: bvt: why not ? they all will look same neh
bvt: you can't verify output of 'write 4096 adds' by hand, though ☟︎
asciilifeform: not having used gcc5+ , i never saw this bug
bvt: ave1's fix also fixed the 'undefined references' in static lib with gcc-6.3 for me
asciilifeform: one would still want to audit the output of any such thing tho, by hand.
asciilifeform: bvt: a typical macroassembler would work for the purpose.
bvt: writing such code really could use some program to generate the necessary amount of adds/subs
asciilifeform: ( ave1 discovered how to guarantee working inlining, and this gave 'free' ~2x speedup )
