BingoBoingo: mircea_popescu: Sub was diesel, but sub and reactor are both outside Argentina's maintenance ability
mircea_popescu: along with a toothpick factory.
mircea_popescu: incidentally, the whole usg "clearance" wank narrowly mirrors the quatari "sponsorhip employment" wank.

asciilifeform: it's a solvable, of course, problem , theoretically 100% of the iron init coad is published . but somebody would have to put in the sweat to port it into e.g. stock uboot.
asciilifeform: then and only then , c101pa will turn into an item like rk, where you can operate strictly with self-built contents
asciilifeform: presently, cuntoo won't run there (even if trinque's process can be coaxed into building arm64 bins) cuz it has no way of blessing the kernel.
asciilifeform: spyked: if you're interested in arm64ifying cuntoo, i recommend to begin with rk.

asciilifeform: apparently at least 4 still-not-gone-for-glue horses in usg's stable ( gavin, buterin, wright, ver )
Mocky: so many damn recruiters. they're like mosquitos in a swamp. they all want to 'have a call' and then 'a skype' 'see if you'll be a good fit'. ugh. two years out of college with a degree in hr, you're gonna decide if i'm worthy to be submitted for a job, and then pressure me to take low ball offer.
Mocky: this is why i worked for the same company for 14 years, i hate this shit. but also what made me soft target for their betrayal
Mocky: i'm convinced this whole ecosystem of outside recruiters is 100% byproduct of startup "investing" that props up the illusion of "high growth" companies that burn thru cash by hiring people so they will qualify for more money
asciilifeform 100% in agreement with Mocky , saecular work suxx
Mocky: the only activity in life that makes me understand why people turn to the bottle
asciilifeform: Mocky: i've even worked in a salt mine where the bottle was Officially (i shit thee not) issued, erry friday at noon.

Mocky: reminds me of "20% time", "work on your own projects on friday since we know you'll be doing that anyway"
asciilifeform: afaik this went away with the 1st 'dotcom' hysteria
Mocky: haven't seen it with my own eyes, even then
asciilifeform: ( and only even existed on paper in west coast sv shitholes; where stipulation was 'IF you've shat out your quota before friday', which typically is approx as likely as in gulag in 1950 )
Mocky: I interviewed with a job once that offered "unlimited paid time off" but inside reports were that anyone who tried to use was instantly on the shit list
asciilifeform: it's unfortunate that mircea_popescu is asleep right nao, otherwise he could tell us about how we're idjits and how working for living is for lusers, and how troo hero can run on sunlight and do as he pleases
Mocky: in truth i do feel like idjit for being old man without the brains to have saved anything. i don't even have a workshop full of shit like asciilifeform
asciilifeform: Mocky: as mircea_popescu is fond of pointing out, workshop is very much 2edged sword
asciilifeform: arguably it is better to be '100% theoretical' and have 'workshop' that fits in briefcase, as e.g. phf does

a111: Logged on 2016-11-29 02:36 asciilifeform: there was iirc something about how an economic landscape stable enough for 'savings' is an ephemeral and quite unnatural thing, rather like billiard table
asciilifeform: it dun even matter so much what the supposed 'savings' are denominated in -- eventually you're out of work and they get wiped.
asciilifeform: reich is set up to ensure that this happens with clockwork regularity to ~erry worker bee.
asciilifeform: ( another great way to lose shirt is 'start company , try to sell useful product ' , a+++ worxxx )
asciilifeform: some folx get to the bottle after 20yrs in workschwitz and cowardice, some after 1,2,3,4 attempts to break out, end result same
asciilifeform: and (at least in asciilifeform's observation) the competent engineer types get to bottle ~sooner~ than the chair warmers.
Mocky: i can't even complain, i ended up with exactly what I wanted as a 20yo, "write software, have a lot of kids"
Mocky: as long as I still had kids at home, never tried to get out

diana_coman: asciilifeform, and the loc is not the whole story either; I'd much rather read *your* 1000 loc than Koch's 100 loc

diana_coman just ate ffa 3, will sign

asciilifeform: on other front, phf : on occasion of the most recent bolix thread , i went and looked again at the http://btcbase.org/log/2018-01-17#1771955 artifact ; it is interesting that they provided 128 iron types, incl. bignum, but not a 'bignum of fixed N words'. i guess in '80s ~nobody was thinking of crypto at all. ( and i was prolly unduly pessimistic to the orig finder of $item, it is prolly 95% of what's needed for cycle-accurate clone.
a111: Logged on 2018-01-17 20:04 fromloper: asciilifeform: someone uploaded "I-Machine Architecture Specification" to Bitsavers three days ago, I thought you might find it interesting: http://www.bitsavers.org/pdf/symbolics/I_Machine/I-Machine%20Architecture%20Specification.pdf
asciilifeform: the tricky bit is that remaining 5% -- ops introduced since that draft, loadable microcode, init logic, etc )
asciilifeform: err, 64
asciilifeform: types.
asciilifeform: aanyways.
asciilifeform: diana_coman: nitpicks / spiffy karnaugh simplifications / etc. welcome as always.
diana_coman: asciilifeform, the only thing re ch3 that I keep circling because not entirely clear why so is the "overflow in means *or* on word"
asciilifeform: diana_coman: btw you may find it entertaining that i found several vers of the carry & borrow eqns in my orig notes -- including yours. but for some reason i originally rejected that variant because it needed 2 accesses to the result D . but i neglected to write down why, possibly was simple brain fluke.
asciilifeform: diana_coman: plox to link to line ?
diana_coman: asciilifeform, http://btcbase.org/patches/ffa_ch3_shifts.kv#L462
diana_coman: i.e. if one shifts right by 2 bits but provides an overflow of 8 bits than 6 of them get simply or-ed, it's not like they get pushed in
asciilifeform: diana_coman: how would a shift by 2 provide overflow of 8 ?
diana_coman: it doesn't provide it, no
asciilifeform: you mean, what if one were to feed it one when cascading ?
diana_coman: yes, feed it one, whether cascading or not; the point is: what is the meaning of overflow in exactly for a shift op?
asciilifeform: it will produce garbage, yes. i considered to make OF_in a limited type, but it would slow down the place where the item is actually used, substantially ( ada does not offer a fast bit-count-on-word operation )
asciilifeform: observe that the operators of fz_shifts are not exported in ffa.ads ( ch11 unified api ) , they are strictly for internal use in the lib.
asciilifeform: this is one of the reasons why.
diana_coman: aha; imho this sort of thing would be great added to the comments there
asciilifeform: diana_coman: i'ma absolutely add it to comment and discuss in ch14 mail bag.
diana_coman: thank you!
asciilifeform: and this is prolly not the only instance of the item. ( i discussed it briefly in ch11 , in the section where preconditions -- ended up moving many preconditions to the exported wrappers, they slow things down quite substantially when present on inner-looped invocations, as they prevent (for obv reason) inliner )
asciilifeform: idea being , exported routines ( current set is shown in http://www.loper-os.org/pub/ffa/hypertext/ch13/ffa__ads.htm ) are to be 'safe on all electrically possible inputs' , with the exception of div0 (user is commanded to test for div0, as example in http://www.loper-os.org/pub/ffa/hypertext/ch13/ffa_calc__adb.htm#172_17 )
asciilifeform: but the same guarantee cannot be given for erry internal component, not without geological runtime.
asciilifeform: i'ma add commentary/warnings when diana_coman et al point out good additional places where; but no one should live with expectation that ~all~ possible ways to break ffa by monkeying with internals, will be listed
asciilifeform: ( the only guarantee i can offer in good conscience is that nuffin can be broken by operating the ~external~ controls -- but even there user is required to see whether his cpu has barrel shifter (see ch13 discussion) , constant-time mul ( see ch9 discussion ) )
diana_coman: asciilifeform, it's not about exhaustive list of ways-to-break, certainly not
asciilifeform: right
asciilifeform: and in principle i'm not averse to adding detail to comments. ( this is exactly the reason why comments exist -- show what is not necessarily evident from the coad )
asciilifeform: incidentally even the currently given 'external api' is eventually to be 'internalized', in the sense that user input is expected to be in P-code (presently named as 'ffacalc') and output ditto
asciilifeform: i.e. one will call, roughly, P(pcodestring, ffawidth, ffaheight, maxsteps) and get output.
asciilifeform: (this is, for most part, already what cmdline does. aside from 'maxsteps' not having yet been introduced Officially, cuz no loops yet)
asciilifeform: diana_coman: i'ma also note, _O_I is used strictly in fz_mod : http://www.loper-os.org/pub/ffa/hypertext/ch13/fz_divis__adb.htm#83_14 ; prolly oughta be inlined ~there~ and abolished as a global (even internally) function.

asciilifeform: at 1 time, was used in the constant entry ( nibble inserter ) routine, then the latter was replaced with rewritten http://www.loper-os.org/pub/ffa/hypertext/ch13/fz_io__adb.htm#29_14 , nao sole remaining use is in the knuth divider.
asciilifeform: orig was writing from pov of 'most general possible set of subcomponents' , but this is not necessarily what is wanted in the end product, esp. from loc-cut pov.
diana_coman: that's fine, note that my feedback is given as I read them so without actual knowledge of what happens later/where exactly they are used
asciilifeform: my current aim is that in ch22 ( see also http://www.loper-os.org/?p=2735 ) any subcomponents not used, are to be cut; and any that have strictly 1 invocation, are to be made sub-functions and remain visible solely in the scope where used.

zx2c4: you dont think the borrow checker eliminates large classes of problems in a performant and somewhat elegant way?

zx2c4: rust's ownership and borrow semantics
zx2c4: hey ffa in ada
zx2c4: nice post
asciilifeform: zx2c4: weren't you here last yr for a 'the technical cannot be separated from the political' and 'if program+all accessories doesn't Fit In Head, it is garbage, not proof' thread ?
zx2c4: no i dont think so
zx2c4: presumably the premise is something along the lines of complexity making things impossible?

a111: Logged on 2018-05-04 17:23 asciilifeform: zx2c4: as a matter of fact, is IS a conclusion i can jump to trivially. because your supposed 'person' is actually a nameless cockroach beneath my feet. because he is not in the wot, and thereby not distinguishable from the 90000..+ faux 'humans' usg manufactures on daily basis to further its psyops.
asciilifeform: zx2c4: point being, i don't practice haskellism. and nit from being illiterate yokel who has nfi how. it so happens that i know how. but consider the whole approach to be braindamaged .
asciilifeform: and, in parallel, to be an organized campaign of sabotage against ~concept~ of actual correctness in programs.
zx2c4: _organized campaign of sabotage_
zx2c4: that's a much larger accusation
asciilifeform: wtf is the point of 'here's a proof but you need this here 100MB of gnarl to ~run~ it and of course you will trust output, or are you a terrorist'
asciilifeform: proof is proof when it fits in head, now just as in euclid's time.
zx2c4: have you seen HACL*?
zx2c4: https://github.com/project-everest/hacl-star
zx2c4: Kind of an interesting project
zx2c4: They write proofs in F* showing equivalence between some functional description and some imperative description
asciilifeform: have seen
zx2c4: And then they're able to lower the F* down into C
zx2c4: Which is pretty readable
asciilifeform: zx2c4: try to think about what i actually said tho
zx2c4: The proof, however, is gone from the C
zx2c4: Well of course everyone prefers simpler proofs that fit in the head
asciilifeform: if you need a 'proof system' to prove $assertion, you have NOT proven it. not to me.
zx2c4: Simpler code that you can read in a sitting
zx2c4: And so forth
zx2c4: But it turns out now all things are so easily provable as such
zx2c4: Not all math is as simple as Elements
asciilifeform: then they aint proven, basta.
zx2c4: Hasn't writing always been a tool to expand our knowledge / understanding / assurance beyond a single mind?
asciilifeform: not fits in head ? not proven. ( i did not say ~whose~ head, but imho safe to suppose that whole f# microshitiana garbage pail fits in no head )
zx2c4: Write down thoughts from one day, use writings to your benefit the second day, and now you're two people in essence
asciilifeform: zx2c4: theorem that dun fit in any 1 skullcase, aint proven.
asciilifeform: this is a political declaration, not an astronomical observation, zx2c4
zx2c4: Oh, I mean, if you're willing to allow for anybody's head (as i presume you mean by mentioning ~whose~ head), then you just posit an incredible genius
asciilifeform: not enuff to 'posit'
asciilifeform: gotta actually exist ( and 'genius' btw is the fella who makes the 'fit in 1 head' fit in 9000. )

a111: 21 results for "heaviside", http://btcbase.org/log-search?q=heaviside
asciilifeform: ^ see also.
zx2c4: I'm not even quite sure what you mean by "fitting"
zx2c4: There are some things I could only prove if I had a paper
asciilifeform: fortunately there is a convenient demo
asciilifeform: ffa. see esp the passage re parachute.
zx2c4: I more or less know the process involved but don't have all of the steps in my head. And as I wrote it down, I forget the details of previously written steps while working out current new steps. Yet I have faith in the process of writing it down systematically and having intermediate results from pages prior
asciilifeform: the statement is quite serious, i and some yet-unknown number of other people will literally bet arse on our grasp of ffa correctness.
asciilifeform: the attribute which permits this approach, vs haskellism and other idolatrous rituals to mechanical molloch, is called 'fits in head'.
zx2c4: > At this time we will walk through the mechanics of our Karatsuba multiplier, so as to cement in the reader’s head the correctness of the routine, and lay groundwork for the optimization which is introduced in Ch. 12B.
zx2c4: Certainly a good pedagogical practice
asciilifeform: let's take from other end of digestive tract. consider 1 AND gate. idealized, no metastability, no breakdown voltages, literally 'ands' two logical values. ( can have physically limited to % of c speed, if you like, but this is uninportant )
asciilifeform: with me so far ?
zx2c4: so this state of "being proven" for you -- it requires some kind of intuitive bullet shot from start to finish of all particulars of a certain logical progression? and any deference of that to outside tools (like paper, or intermediate results with forgotten details) ruin the intuition?
asciilifeform: lemmas ok, paper ok
asciilifeform: so long as in the end it clicks in your crankcase and is as obvious as that and gate.
zx2c4: alright and you'd freely admit that when you write things down and solve intermediate lemmas, its often the case that by the time you get to the end, you don't have in the forefront of your brain the details of all intermediate steps anymore
asciilifeform: grasp obvious in its totality, as in there is literally NO hesitation to strap the thing on and 'if mistake -- any mistake -- i hit cement at terminal velocity'
asciilifeform: zx2c4: i like paper. and even chalk.
asciilifeform: but they are devices for eventually rearranging contents of your head, permanently, rather than substitutes for head,
zx2c4: so perhaps you prefer chalk and slate to paper then
asciilifeform: i sometimes even use computer algebratrons, in exploratory work. but would never consider presenting output straight from one as 'here, correct'
zx2c4: a temporary buffer, rather than a rolling log
zx2c4: sage?
zx2c4: z3?
asciilifeform: 'derive'
asciilifeform: ( on some occasion, also macsyma )
asciilifeform: but is immaterial, next will ask what kinda chalks.
zx2c4: haha, was just curious. i presume you're ancient
asciilifeform: depends how you consider
asciilifeform turns 35 next wk
zx2c4: oh. then derive and macsyma surely are jokes
asciilifeform: deadly serious.
zx2c4 stares
asciilifeform: ( wait till he learns that asciilifeform has a fleet of e.g. dos boxes. )
zx2c4: just install Coq for heavens sake
asciilifeform: or that FUCKGOATS rng is built to speak rs232 at 115200 baud and always will be
asciilifeform: or that ~ nuffing in asciilifeform's machine room postdates '09
zx2c4: hey i like good ol rs232 too
asciilifeform: zx2c4: whole reason i bother with this thread is to explain why no, i would ~not~ like to suck the coq, if you will
zx2c4: I agree with you in spirit -- I think learning details of a proof enough that you have all of it in your head is a good pedagogical approach and gives you more mathematical agility as you progress forward. I just don't know about the ontological statement regarding the proof's validity
asciilifeform: haskellism is like dope for intellectually-bent folx. it is addictive but ultimately ruin.
zx2c4: (coq is from the late 80s. its still in use, but i guess you could use the 2009 version...)
asciilifeform: intellectual bankruptcy.
asciilifeform: zx2c4: lemme ask, on what authority am i to accept the correctness of a proof generated via e.g. coq ?
zx2c4: i can see that critique of haskellism. endless intellectual masturbation (hello trilema?) that doesn't actually drive at any essential truth. there's a particular benefit in demanding truths remain small rather than large
asciilifeform: i have not read src of coq, to do so would take 20yr ( and i dun mean 'skim', but to find total proof of correctness of whole shebang and load into MY head )
zx2c4: well, as it turns out, coq had some amazing fallacy in its core code a few years back resulting in the ability to prove any statement true...
asciilifeform: and i'm to take it seriously after that ? pray tell why ?
zx2c4: it's convenient?
asciilifeform: as it is i have less nausea for even honeopaths than for mecha-proof folks
zx2c4: more seriously, if you're mostly after small computer programs to help you out when exploring a field but eventually do the proof by hand, z3 and sage wind up being super practical as day to day work horses
asciilifeform: homeopaths at least only bamboozle the irredeemably stupid
asciilifeform: zx2c4: you may find it interesting to learn that i once worked in a dour 'salt mine' where shat out 'correctness proof' all day. in 'sage.'
zx2c4: (i learned algebra back in the day from a professor who wrote a haskell program to generate our textbook... presumably in your mind, my foundational education could not be more screwed up https://en.wikipedia.org/wiki/Dave_Bayer )
asciilifeform: 'darpa' paid.
asciilifeform: sucked beyond my ability to describe.
zx2c4: z3 is nice for things like
zx2c4: https://xn--4db.cc/ltPtHCKN/py
zx2c4: https://git.zx2c4.com/WireGuard/tree/src/crypto/zinc/poly1305/poly1305-x86_64-glue.c#n72
zx2c4: that z3 script gives a little more assurance we didn't screw up the radix conversion here
asciilifeform: it was a misery. and 'sage' made it ~more~ of misery, if yer gonna commit 'machine proof' atrocities, has no biz doing in a non-homoiconic lang (i.e. any non lisp)
zx2c4: heh
asciilifeform: zx2c4: lemme ask you this -- those mecha-proofs of yours, how much do you actually believe in'em ?
asciilifeform: i.e. wouldja bet life of self, wives, pets, whole clan of yours, on there being no boojum in coq, z3, other claimed brain substitute of the day ?
zx2c4: no. they're mostly just tools
asciilifeform: i'd hope that i dun have to explain that when you write a cryptosystem, you are in fact asking other people to do this.
zx2c4: to do what
asciilifeform: to jump on ~your~ parachute, that you sewed.
zx2c4: oh. yea, as i said, they're mostly just tools
asciilifeform: tools for what ?
zx2c4: an additional check against my feeble human reasoning
asciilifeform: how wouldja describe for what
zx2c4: it also lets me try things super fast without thinking
zx2c4: and then think backwards in order to reason about its correctness later
asciilifeform: so like paper ?
zx2c4: sort of
zx2c4: more efficient paper
asciilifeform: then why do you advertise and publish the 'proofs' ?
zx2c4: huh?
asciilifeform: i dun publish my 'derive' barf
asciilifeform: or chalk board contents
zx2c4: i think in crypto most people refer to it as "verification"
zx2c4: rather than proof
asciilifeform: whereas 'here is my z3 proof' is typically published for cachet among haskellist co-religionists
zx2c4: i save my z3 script so that
zx2c4: later if im changing the code
zx2c4: in addition to reasoning about it
zx2c4: i can quickly re-check my work
asciilifeform: it dun verify jack shit. is machine barf. just like the raw output of your compiler, except less meaningful
zx2c4: make sure i didnt so something immediately dumb
asciilifeform: if you can follow the proof by hand
zx2c4: in the example above, its pretty easy to prove that by hand
asciilifeform: can you, for the one for that routine you linked ?
asciilifeform: how much does it weigh ?
zx2c4: it's not bad at all
zx2c4: its a radix conversion
zx2c4: highschool contest math
asciilifeform: lessee the proof ?
zx2c4: fair enough
asciilifeform: what i see in the link, is a buncha c code, with pointerisms
asciilifeform: does your proof demonstrate that none of them can overflow, regardless of what happens , say ?
zx2c4: right. shows that the carrys work out without overflows given certain bounds on the input
asciilifeform: ... or that the #define ULT(a, b) ((a ^ ((a ^ b) | ((a - b) ^ b))) >> (sizeof(a) * 8 - 1)) macro dun turn to barf in the preprocessor on acct of some esoteric beard shaving from dennis richie ?
asciilifeform: and i could continue..
zx2c4: "unsigned less than"
zx2c4: dennis probably wants those variables surrounded by ( )
asciilifeform: consider, zx2c4 , i can show that nuffin in my arithm routines can overflow a buffer. even if you were to turn ada's overflow checks off. without any complicated tooling.
zx2c4: with good comments? or some nice feature of ada? or easy arithmetic youre implementing? or what?
asciilifeform: i can show this because the inputs , for given size, literally do not affect the program branch flow.
asciilifeform: zx2c4: with bare hands.
zx2c4: carrys/overflows are handled explicitly or something?
asciilifeform: consider to read the series.
asciilifeform: http://www.loper-os.org/?cat=49 << convenient link.
zx2c4: what you've described sounds good. im wondering if it's the result of comments, the result of just better organized code, or the result of some nice features of ada you're using
asciilifeform: no magical feature of ada
asciilifeform: tho it does helpfully give pascal-style pass by ref, to avoid pointerisms
zx2c4: explicit carries everywhere, cool
zx2c4: what's W_Carry?
asciilifeform: it is result of the specific mathematical approach taken. where code must remain SMALL and NO branching on cryptobits, other than death on div0, is permitted. no memory indexing on cryptobits, either.
zx2c4: or, rather, where can i see the implementation of W_Carry
asciilifeform: zx2c4: see ch1
zx2c4: Shift_Right((A and B) or ((A or B) and (not S)),
zx2c4: Bitness - 1)
zx2c4: aahh that trick
