phf: that approach to routing is also described in SCHEME81 paper
asciilifeform: mircea_popescu: i experimented with this personally
mircea_popescu: unrelatedly and i guess unhelpfully, i'm wondering if once specified as above, you don't also get a router for cheap (through implementing a sort of physics where routes attract each other and are repulsed by things etc)
phf: right, you kind of run into the fact that you have to have a set of CAD primitives underneath :/
asciilifeform: (and, on silkscreen side of things , in fact reduces directly to it )
asciilifeform: phf: tracks also have variable geometry of turn
phf: a bus is a track (what i called route) that's reused by multiple components , and if track has coordinates for meanders and thickness you're there
asciilifeform: to give some vague idea of complexity, 'eagle cad' is of about ~same binary mass as trb.
mircea_popescu: none of this is looking terrible so far.
asciilifeform: vias connect 2 or more layers together.
asciilifeform: phf: pcb has track thicknesses, and also meanders (tracks whose shape is hard-specified)
asciilifeform: (nobody wants to look at a 128bit bus as motherfucking 128 lines running in parallel!!!)
phf: to make a pcb out of a netlist, at worst case you need w/h of component, x/y placement of component, a list of x/y coords for each route (to indicate turns)? or there's something that i'm missing?
asciilifeform: phf, mircea_popescu : that's aaaalmost all of it. you also need, in especially large schematics, to collapse buses into single, thick lines (in 'eagle', normally blue, but it does not matter, so long as distinct) and the leadouts from said buses are normal nets, which are marked.
mircea_popescu: <phf> asciilifeform: in the worst case is there more required than a w/h for each defcomponent, x/y for each make-instance component and (list (x y) ...) for eah make-instance route? <
mircea_popescu: no i get that part.
phf: asciilifeform: going back to my previous question though
asciilifeform: (think, recall children's game of 'help the mouse find the cheese' ? that's what a shit schematic looks like)
asciilifeform: so you want to lay the lines so min cross.
asciilifeform: crossing lines make for a turdalicious schematic
mircea_popescu: i mean... we pay $$$ to generate rng. how did the computer generate 5mb to pad what alf declares "minuscle" ?
asciilifeform: mircea_popescu: it's an elementary case of travelling salesman
mircea_popescu: what exactly is the source of complexity in all this ?
asciilifeform: mircea_popescu: there is a related and important (to rsa) mathematical problem, of 'how many bits of modulus give your guaranteed polynomial factoring'
a111: Logged on 2016-12-12 16:28 asciilifeform: oh in re: 'golden 1990s': i recently contemplated making a game-playing box to 'unwind' with, and looked into where to get a decent flying-joystick. and apparently the best ones were made in 1990s, and today sought after, and rare...
phf: http://btcbase.org/log/2016-12-12#1582124 << the best home planetarium mahcine is a toy made by nintendo in the 90s for going ~~$2000 "why you need a pinhole sky projection, when you have ipad???11" ☝︎
mircea_popescu: back to the much more interesting thing of "minimal helping hand" :
asciilifeform: trinque: ...not the titanic you wish you had!
trinque: you sink with the littoral you have
asciilifeform: it is made of the duct tape i have, not the duct tape i wish i had
mircea_popescu: alf fictitious world built out of alf confusing his habit with teh werld.
mircea_popescu: anyway. this whole "google finds thing" is very much of the nature of "i couldn't get dxf to print ON ANYTHING svg conversion IS IMPOSSIBLE" etc.
trinque: whole world is doomed to be rewritten.
a111: 3 results for "doomed to rewrite", http://btcbase.org/log-search?q=doomed%20to%20rewrite
asciilifeform: !#s doomed to rewrite
asciilifeform: trinque: no good, at least not as such, they are stored as strings of decimal digits.
asciilifeform: a very limited (functionally) BUT fully tmsrtronic fallback for imperial crapolade -- is the ticket.
trinque: pg does that.
mircea_popescu: at least take bite out of it.
asciilifeform: betcha i could finally demolish the 'dark matter' of weak-but-not-popped (by birthday-theorem) mods etc.
mircea_popescu: not a meritless idea, that.
asciilifeform: one of the things i would like to do in phuctor (when?? in peacetime...?) is to actually sort the mods by levenshtein distance
phf: asciilifeform: this goes back to the books thread we had long time ago. in-wot solution should exist and be up to tmsr standards. but if you're going to search for books in irradiated library ruins you just have to accept that you have to wear a hazmat and that you might get raped by feral locals.
mircea_popescu: we're going towards it, what with the slowly growing log processing.
asciilifeform: that being said, some reasonaby standard way for wot folk to offer one another search of ~own~ wwwtron -- would be spiffy imho
mircea_popescu: that's the whole matter.
mircea_popescu: the point is - features do not appear TO satisfy. they appear BECAUSE we can.
mircea_popescu: not even the point.
trinque: there was a thread on how to approach the search problem, awaiting some intrepid guy yet.
asciilifeform: mircea_popescu: you , in particular, could probably quite easily 'go knuth' or rms and use the net via courier.
mircea_popescu: nobody wants anything. the google i use will be l-distance based and that's all.
asciilifeform: if someone wants to show me a parallel world where they are all in my wot -- i'm all ears
phf: asciilifeform: in the worst case is there more required than a w/h for each defcomponent, x/y for each make-instance component and (list (x y) ...) for eah make-instance route?
trinque: itt alf shouts things we all know
mircea_popescu: i've long ago decided stuff isn't going to be built to satisfy you ; but over your hairpulling objections.
asciilifeform: heathendom is where chip vendors, cad vendors, 1,000,001 things, live.
mircea_popescu: (conversely : search is a political tool, nothing else. "i just want to" jwz doesn't exist in practice)
asciilifeform: mircea_popescu: the problem is that THEY get it from search !
mircea_popescu: stuff that wasn't linked by anyone linked by anyone in l doesn't exist anyway.
asciilifeform: phf: this is correct, but i will point out that schematic is easier problem than pcb -- schematic traces take up 0 space, and the crossing penalty is merely aesthetic rather than physical
mircea_popescu: asciilifeform very possible dawg, just wot-index the web.
phf: minimal helping hand is the kind of stuff you would manually do to an autorouted schematic, i.e. explicit xy placement for some of the components. algo can simply unpin each component in order and see if autolayout still results in same placement, in which case the explicit coordinate is unnecessary
asciilifeform: i will admit to having serious doubts that building 'like google in 2001, and stays that way!111' is technologically possible -- it is an inherently centralized animal and will grow usg barnacles regardless of who builds it or where it is kept
asciilifeform: it still won't make sane search engine materialize out of the aether.
asciilifeform: phf: unsurprisingly. and the eventual model is chinese google
a111: Logged on 2016-12-12 15:18 asciilifeform: then i suppose the rot - continues. rotten, maggoty google is still the closest thing i know of to working search engine for www...
asciilifeform: let's approach the problem bottom-up, as gedankenexperiment. it is np-complete problem to draw a polished, readable schematic from netlist only. what, therefore, is the minimal 'helping hand' that would let the machine draw schematic from netlist in polynomial time. that is the necessary format, and nothing else.
mircea_popescu: myeah, there is that.
asciilifeform: and iirc clim has something of the kind (though i am the very last who would know the detail)
asciilifeform: i linked to henderson's paper here long ago
asciilifeform: but only topology.
asciilifeform: there are sane ways to do vector graphics
phf: but notably colorforth CAD that chuck moore wrote is all discrete units for these very reasons (there's a writeup somewhere in the CF pile)
asciilifeform: phf: aha, it is not as simple as simply throwing away 'after 3rd decimal place' or the like.
a111: Logged on 2016-12-12 14:25 asciilifeform: discretized the floats, round the thicknesses to 2 places, etc
phf: http://btcbase.org/log/2016-12-12#1582015 << i actually tried one of those against the svg, and without netlist knowledge it gets funky (edges don't properly touch nodes, because rounding) ☝︎
mircea_popescu: yeah, turns out they tried to do an "arab oil shock", didn't work out
mircea_popescu: i recall they had a bumper crop right ?
mircea_popescu: sure they were. from afghanistan to vietnam, all through.
asciilifeform: (and the poppies -- growing. recall, were they growing in 2001 ?)
asciilifeform: -- to keep corridor open.
asciilifeform: which is why usg fought the afghan war

phf: http://btcbase.org/log/2016-12-12#1581952 << ircbot and logbot don't actually depend on each other in V sense, so there's not much i can do about it (unless i'm missing the issue) ☝︎
asciilifeform: well yes, that treatment is reserved for ru
pete_dushenski: it's branded as 'evil chinese opiod flooding in from kongkouver port' around here. so like reverse opium warz, ie. non-round eyes fiatolistas are profiting and this is a Bad Thing.
asciilifeform: pete_dushenski: the reason why crackdowns on 'prescription dope' is that it is not feeding hard currency to lizards, but fiatola to variably-connected fiatolists
asciilifeform: and it happened quickly enough to be visible to naked eye
pete_dushenski: thus all the fuss about fentanyl, which runs along the lines of "it's so potent and so profitable and killing all our youfs!", behind which the obvious inference is that only the state should be profiting and killing youths.
asciilifeform: spain lost its colonies, and autoimmunologically devoured itself, was the thesis.

asciilifeform: mats: aha, see the mega-piece re 'autocolonization',
mats: white people have moved from enslaving a generation of chinese males with opium to ...
asciilifeform: aha, was about to mention opiumwar
mircea_popescu: at least back in the day when it was called "british empire".
asciilifeform: when you cut away the noise, it's little else
thestringpuller: damn this reminds me of that frank lucas shit
BingoBoingo: pete_dushenski: Not yet, will take apart later. Perhaps it is the mispellings, however funny. Illiteracy is popular among spamzors.
pete_dushenski: any idea why scarfed ? trilema links should be kosher
