mircea_popescu: facts aren't open to engineering, they're the subjects o' science.
ben_vulpes: myeah, dent test don't make so much sense applied to ceramics
ben_vulpes: well this is the job of engineer, select correct materials for correct applications.
mircea_popescu: notwithstanding that in many applications in the past back when we were 3 yo those were equivalent categories.
ben_vulpes: different ~everything; what, make me a strand of wood fiber as thin as spider silk and let's test it
ben_vulpes: need to know, or heuristicate, how much ceramic to make the handle out of
mircea_popescu: it is a very uninformed argument. in point of fact the "Fragile" spider web is one of the strongest materials known.
mircea_popescu: ben_vulpes not so. dimension here is not properly taken as "same kg" or "same m3"
mircea_popescu: but this hides the proper argument. ben_vulpes would you say "paper is stronger than spider web, i can tear the latter without noticing" ?
ben_vulpes: anyways, same-dimensioned columns of steel and china/ceramic; ceramic column will assplode under load that steel blinks at
mircea_popescu: asciilifeform both items used in the intended manner. sword, as sword, cup as cup.
mircea_popescu: (million dollars is perhaps not enough to buy either, but let's pretend fiatola has some modicum of value)
mircea_popescu: understand : if you spent your million dollars to buy knight's sword, it came with a "will not make it 20 years" guarantee. if spent same million dollars to buy china set, it came with "forever as long as your family line shall be" guarantee.
ben_vulpes: see the recent discovery of cavalier swords at hadrians wall
ben_vulpes: mircea_popescu: oxidization plays a role in the loss of steel
mircea_popescu: ben_vulpes understand, MOST historical porcelain ever made survived. this is very not true of steel, which ~all broke.
mircea_popescu: asciilifeform that's how it's dealt with, yes. improved mix, it's not straight up enammeled clay eh.
asciilifeform: but i do wonder if this could be dealt with by mixing in steel wool or fibre or similar
mircea_popescu: intuitively it may seem "oh, it's brittle", because whatever, dropped mom's china. but this intuition is wrong.
ben_vulpes: mircea_popescu: under what conditions is steel more brittle than ceramic?
mircea_popescu: every material is to a degree brittle much like every material is to a degree warm.
asciilifeform: that ain't the problem
mircea_popescu: yes but your discussion is weak. porcelain is harder than you understand.
asciilifeform: discussed in thread
a111: Logged on 2017-09-12 17:49 BingoBoingo: * asciilifeform seriously considered getting one done << Eh, go porcelain. Make and fire just like tile. Turk up your keys!
mircea_popescu: http://btcbase.org/log/2017-09-12#1712538 << this is not a bad point, showing a fine understanding of the history of huma nthought. fabrication of wear resistant small pieces went through a century old porcelain phase yes. ☝︎
mircea_popescu: "Elaine Ou is a blockchain engineer at Global Financial Access, a financial technology company in San Francisco."
deedbot: http://qntra.net/2017/09/preet-reduced-to-panhandling-disc-jockey-again-demonstrating-costs-of-opposing-republic/ << Qntra - Preet Reduced To Panhandling Disc Jockey, Again Demonstrating Costs Of Opposing Republic
asciilifeform: i forgot to mention bit-shifts , but these are obviously also available.

asciilifeform: ( the rsa operation, the one and only, is modular exponentiation. but it is made trivially from modular multiplication . )
asciilifeform: goal is, state a modular multiplier , takes A, B, N, (each is a B-bit number) and yields a B-bit result R, where R = a*b mod N .
asciilifeform: you have the following primitives : multiplier ( 2 N-bit numbers -> 1 2N-bit number ); adder ( ditto ); subtractor ( ditto ); muxer ( 2 N-bit numbers, 1 single-bit number, yields one or the other N-bit depending on that single bit ) ; logical ops (and/or/xor/not) ☟︎
asciilifeform: again you don't need to state it in compilable ada
asciilifeform: if ben_vulpes et al want to try their hand , i'll read
asciilifeform: this is in fact the only item holding up release of 'p'.
ben_vulpes: i eat from tin pans i salvage from the midden, just like you.
asciilifeform: it is a deliberately crafted insult to actual people.
asciilifeform: would you eat from trough made for a pig ? that's what using plebekbd feels like.
asciilifeform: i spend 14+hrs/day with the thing in my hands, and it makes a difference.
ben_vulpes: every man in teh failed states of americastan gotta pick which things to salvage from the midden to cobble a life together from.
ben_vulpes: http://logs.bvulpes.com/trilema?d=2017-9-12#202821 << my favorites, just like engines! proper engine should be house-sized thing; run in steady state or not at all.
ben_vulpes: release your attachment to the perfect devices of years past, it but causes you suffering
ben_vulpes: asciilifeform: it's all dead. we live in the ashes.
ben_vulpes: what was the method for making these?
asciilifeform: there is to be no slip of the ratchet, no 'doctor cured your ear, but poked out an eye'
asciilifeform: understand, right here i have almost 40 y.o. keycaps that looks EXACTLY as when new.
asciilifeform: surfaces are to be smooth.
asciilifeform: ben_vulpes: i dun want to FEEL THE LETTERS OMFG
ben_vulpes: asciilifeform: could etch the letters in; carve them out with a cnc mill. 'tis not the end of the world.
BingoBoingo: Now that this is decided, refocus to rest of the thing
asciilifeform: what part of this is hard to understand.
asciilifeform: ( and if you make it not propagate - you automagically get a thing that I WILL NOT USE because it ain't propagating to my fingertips )
BingoBoingo: Even then, rest of switch mechanism doesn't have to be ceramic. Just the keycaps. Solves problem of letter wear. Everything else can be buttjection molded whatever, as long as it is soft enough to not piss of keys.
BingoBoingo: What are you banging it into that it can't be keycap on top of fiber cement subcap? (i.e. like a floor)

a111: Logged on 2017-08-10 19:45 asciilifeform: forn00bz: an, e.g., rsa modexp, in ffa, must be representable by a long roll of paper, on it are ops for ordinary 4function calculator, with very patient slave. and roll ONLY ROLLS FORWARD and has finite # of instructions on it, known in advance when you decide the ffa width.
a111: Logged on 2017-09-12 06:28 trinque: asciilifeform: any reason not to define VERSION in knobs.h ?
a111: Logged on 2017-09-12 06:29 trinque writing standalone tools for key->addr doodling, and eventually txn manip., had to define VERSION at the top of each.
mircea_popescu: anyway. off to bed, this has been too much. laters!
asciilifeform: for humanlang textentry, even a very threadbare kbd is notbad
asciilifeform: nah i know a buncha folx who dun care at all. they work with... pens
mircea_popescu: anyway, i suppose i'm the only one that doesn't actually care all that much.
mircea_popescu: (note that all key arrangements, from atms to dishwashers, are in a rectangular pattern ; and i expect alf wants them radial or something)
asciilifeform: i dun think they do 6axis cnc
mircea_popescu: there's like... i dunno, 8 total alive or somesuch.
mircea_popescu: what you need is one of those 50yo slave guys who spend life making chain mail and surgical steel stilleto heels.
asciilifeform: if it only needed pcb, everybody would just call up favourite pcb fab and then stfu
mircea_popescu: with good wear characteristics, andthen the item wants to retail for 20 bux.
asciilifeform: ( lettering, to an adult man, on a kbd -- is optional. how often do you look ? )
asciilifeform: which is the only thing that could not be done with massaged 'model f'
asciilifeform: in my case i would even be content without letters, but simply to control the number and ~placement~ of keys.
mircea_popescu: seems hardly worth the hassle. but anyway.
a111: Logged on 2017-09-12 03:34 trinque: anyhow I'd accept the bespokenness of key labels as a start
asciilifeform: hypothetically ( actually trinque was the one who asked , http://btcbase.org/log/2017-09-12#1712398 ) ☝︎
mircea_popescu: you want your keyboard to have special letters on it ?
asciilifeform: is what thread was about. ( and that is at the minimal, in my case i also want to fit existing pistons , and req'd luft is no larger than what is permitted in rifle barrel )
mircea_popescu: unless you're getting your fingers measured for the key size or some shit.
mircea_popescu: asciilifeform that difficulty is in no way particular. keys are commodity items.
asciilifeform: the only known satisfactory method is called double-shot injection molding, where the letter is cast ( yes, physical shape, e.g letter A ) and then key is cast ~around~ it
mircea_popescu: ie, when at the height of soviet obamacare you broke your leg and your mother made you an ad-hoc wooden contraption to fix it, she DID in fact bespoke you a traction, even if it sucked so bad as to compare negatively to african healthcare.
asciilifeform: i.e. the keys.
asciilifeform: the item directly to do with bespokeness is the difficulty of shaping heterogeneous solid objects with 0.01% accuracy.
mircea_popescu: but this has nothing to do with the bespokeness.
asciilifeform: in thread, 'model f' is approx. a top hat.
asciilifeform: you would if you wanted a top hat!11
mircea_popescu: but i've yet to have a special textile plant made for it.
asciilifeform: plox to concretize : when mircea_popescu goes to get a suit made, what kind of fabric does he specify ?
mircea_popescu: there's a substantial difference between "i don't like this" and "this doesn't compare favourably to rando coworker's item". these two can never mix. this isn't sophistry, but plain sense.
mircea_popescu: if "mass-produced plebeshit as minimal bar" is your criterion, then it definitionally is not bespoke. because it's not compared to you, it's compared to the mass.
mircea_popescu: either the first part, or the second part. you can't mix these.
asciilifeform: it means 'exactly as i want, with the mass-produced plebeshit as minimal bar'
mircea_popescu: asciilifeform that doesn't enter into it.
asciilifeform: would mircea_popescu accept 'bespoke' suit that in ANY way (aside from cost) falls short of mass-produced liquishit plebesuit ?
mircea_popescu: they still use commodity fabric, furnishings etc. they just tailor it to your ass is all.
asciilifeform: this means that the chassis is custom. out of what do you propose to make it ?
asciilifeform: let's forget model-f pistons and flappers. which aren't made today, and can only be made with injection mold. take, at the very minimum, that you decide how many keys, and where they go.
mircea_popescu: gimme a break. the letter A isn't your invention.
mircea_popescu: eh, qty of one. "omfg, do you know what it means to make a planet on which snakes might evolve so as to have material FOR BUTTONS?!?!?!"
