shinohai: I started some work on this over a year ago, simply too much work for me because of irl obligations unfortunately.

asciilifeform: and no, not 'enough', i'd like to find out wtf apeloyee was thinking
asciilifeform: specifically, why :
asciilifeform: subtype Stack_Positions is Natural range 0 .. Height;
asciilifeform: type Stacks is array(Stack_Positions range <>) of FZ(1 .. Wordness);
asciilifeform: - Stack : Stacks(Stack_Positions'Range);
asciilifeform: + Stack : Stacks(1..Height);
shinohai: Logged: 09:17 +Hasimir and yes, libgcrypt is part of the larger project, Werner and Niibe are at the core of GNU security.
asciilifeform: the proper way to enforce 'no access to Stack(0)' would be to constrain Stack_Positions to 1 .. Height. but this leaves no way to represent an empty stack.

diana_coman: esthlos, certainly, not an issue; I think you are overthinking/overreading into this
shinohai: Well as diana_coman said, Eulora encourages one to customize to one's liking.
shinohai: You can play with pen and paper, I'm sure, if you find a method for so doing.
diana_coman: and fwiw see history of foxybot: it started precisely like that, as a player-made-for-own-use thing and it ended up bundled into "official" client

shinohai snail-mails diana_coman all my claim updates, looks around forlornly as they all vanish into lbn ....
diana_coman: now hmm, where was that bit written on trilema
apeloyee: MustNotZero has 0 to do with Stack(0) << I know.
shinohai: Round 1 .... FIGHT, FIGHT, FIGHT!
apeloyee: Hear, hear! If asciilifeform would agree to take discussion of why 1+1=2 elsewhere, I'll do.
asciilifeform: apeloyee: let's hear the answer to the riddle ?
asciilifeform: i'ma listen
apeloyee: which.
asciilifeform: both parts
apeloyee: the change to size Stack in the first paste was irrelevant
apeloyee: *size of Stack
asciilifeform: that part i get, it doesn't have anything to do with the clobbering of the modulus
apeloyee: why should correctness depend on order of the arguments?
apeloyee: (on FFACalc stack)
asciilifeform: because we're overwriting an input ?
asciilifeform: could just as easily not, with temp buffer. but why.
asciilifeform: it is not my place to make every possible mutilation of the program, safe. ( and is quite impossible )
asciilifeform: prolly FZ_Mod_Exp oughta accumulate Product in a temp, and shit it out in 1shot in the end, like FZ_Mod_Mul.
asciilifeform: though it is a waste of space and time.
asciilifeform: i never proclaimed, fwiw, that all ffa routines must be able to cleanly walk over own inputs.
apeloyee: what functions can tolerate aliasing of arguments is talked of precisely nowhere. and it's easy to forget about that when changing them later. and aliasing is used extensively.
apeloyee: so can't say "don't do that"
asciilifeform: used extensively ? where, other than the stack ops ?
apeloyee: FZ_Mux
apeloyee: is invoked many times with output = one of inputs
esthlos: diana_voman very likely am over thinking things
esthlos: lol diana_coman
asciilifeform: has apeloyee found a specific instance where it can be made to eggog ? or is this a hypothetical 'once less clueful people start changing things' observation ?
esthlos: I will proceed one step at a time
apeloyee: the latter.
asciilifeform: because there isn't actually a limit as to what less-clueful people can break, regardless of what i do
asciilifeform: but i can't help but agree with apeloyee re the Product in FZ_Mod_Exp , it gotta be buffered.
diana_coman: esthlos, lol! auto-completion helps
asciilifeform: the cost is small in comparison with the mod-exping per se
apeloyee: this can be used to justify pointer arithmetic and what-not. Just don't do unsafe things!!
apeloyee: FZ_Mod_Mul also
asciilifeform: the ch7 one ? yea
apeloyee: (as implemented in chapter 7, but not chapter 6)
asciilifeform: i'ma buffer'em.
asciilifeform: really all routines oughta behave consistently in re input-overwrite.
shinohai: Diana Voman sounds very Soviet to me for some reason.
asciilifeform: this is a bit of a downer, i confess that i hoped apeloyee had found a more subtle, lethal boojum.
apeloyee: and add a new exercise: re-read all previous chapters and write what aliasing of arguments is safe
apeloyee: nope,sorry
asciilifeform: apeloyee still wins 'most attentive eagle eye' award.
asciilifeform: the 1 caveat re buffers, is that there is a practical limit as to what can be made anticlobbering: if i were to do it to items that occur in inner loops of O(n^3)istic items, e.g. mux, proggy will end up 'geological' 4ever.
apeloyee: I think everything up to ch.5 is safe as long as arguments are either equal or don't overlap
apeloyee: *memory locations of the arguments
asciilifeform: afaik it isn't actually possible to write overlap-safe routines without implicit (or otherwise) branches
asciilifeform: in the general case.
apeloyee: does gnat provide a facility to check aliasing at runtime?
asciilifeform: partially ( for array copies ) . but it gets nuked by No_Implicit_Conditionals.
asciilifeform: ffa itself is a sort of tightrope walk, an attempt to 'и рыбку съесть и нахуй сесть' . it isn't actually possible to make all of the routines able to take every conceivable kind of compile-time abuse ( which i'd argue overlap of arguments, is ) without conditional jumps.
apeloyee: conditional jumps are OK if one of the destinations just aborts the program
apeloyee: as with MustNotZero
asciilifeform: right, e.g. the range checks
asciilifeform: ( they don't appear in the code, but they exist )
apeloyee: aliasing checks are like range checks in this regard
asciilifeform: No_Implicit_Conditionals does not affect such jumps however
asciilifeform: ( observe , they are still present in the disasm )
apeloyee: then why "it gets nuked by No_Implicit_Conditionals."? wreckers (tm)?
asciilifeform: it isn't a wrecking
asciilifeform: and afaik gnat does not know how to prevent aliasing in the general case, but only in a few specific situations ( array copies )
apeloyee: well, ideally it would have a "No_Out_Arguments_Aliasing" restriction which would insert runtime checks
asciilifeform: but afaik no such item exists , even in '2012'
apeloyee: gnat implements many nonstandard restrictions
asciilifeform: possibly one can make a SPARKistic proof of non-aliasing , for proggy taken as a whole. i'ma look into it.
asciilifeform: thing is, a sparkism is not a substitute for a 'fits-in-head'-correct routine.
asciilifeform: proggy ought to be written in such a way that the reader can ~see~ that it is correct.
asciilifeform: this is the #1 type of stylistic fix that i look for -- 'can this be made more obviously-correct-when-used-as-prescribed' and 'can use-as-prescribed be made more obvious'
apeloyee: yes. hence me bringing this item here
asciilifeform: aha. ty apeloyee , for taking the sweat to do this.
asciilifeform: i'm still curious re the SP tho
asciilifeform: can you think of a way to have the range of SP and of Stack be the same, but to still represent concept of 'empty' ?

shinohai: Gotta sell all my Bitcorn before the Missus finds out I spent all our monies on the Bitconnect ponzi.
apeloyee: can you think of a way to have the range of SP and of Stack be the same << this is plainly absurd. a N-sized stack has (modulo contents) N+1 possible states: "0 elements", "1 element", ..., "N elements". i.e.the ranges MUST differ, by exactly one.
BingoBoingo: In other shithole factories: meltdown/specte patches are making a bunch of industrial systems wobble! Chinesium's about to get a low more Pinoy
asciilifeform: apeloyee: i dunget why absurd ? my other arrays behave this way.
asciilifeform: i.e. in all cases where the array has a custom indexing type as the index, the array exists over the entire range of said type.
asciilifeform: apeloyee: a long-term goal is to have the whole proggy bulletproof even after building under '-gnatp' ('disable all range checks'). relying on the range check of Stack , vs SP's range, does not go well with this
apeloyee: Logically, SP isn't a reference. It's a cursor, showing the boundary between the valid and invalid elements. If a line in a text editor has N sybols, then a cursor has N+1 valid positions. (Consider that an empty line sill has 1 valid cursor position).
asciilifeform: ideally there would be some way to trap any reference to the zero cell, or , failing that, to prove that the zero cell cannot end up referenced.
asciilifeform: apeloyee: well yes, i get it. but i DON'T LIKE it.
asciilifeform: i'd like to resolve the apparent contradiction between 'all possible SP positions are valid dereferences' and 'stack can be empty'.
apeloyee: an extra element won't save the father of russian democracy (c), if FFACalc stack manipulation code is wrong; e.g. if a 'Want(X)' statement is omiitted
asciilifeform: right. but why would it be omitted.
asciilifeform: one way i considered doing this, is to do away with all such things as 'SP - 1', 'SP - 2', etc. and instead to have e.g. Get_Stack_First, Get_Stack_Second, etc., each of which individually would ensure that the desired element exists. but these would have to return 'access type' (pointers) which thus far i've avoided using .
apeloyee: if FFACalc code is correct, then it's also safe to omit that zero-indexed element from Stack
asciilifeform: this is true. but 1) ugly 2) possibly will get in the way of sparkism, later; it relies on type ranges for good chunk of the proofolade
asciilifeform: hmm, what if one were to model SP as in apeloyee's analogy, the text editor cursor. i.e. the pos of the ~next~ valid stack cell, rather than 'current'.
asciilifeform: then to refer to current, would be 'SP - 1' rather than 'SP'
apeloyee: no need
apeloyee: cursors are pointing _between_ elements
asciilifeform: well it'd turn a pop from empty stack into a range-dipping eggog instantly
asciilifeform: and abolish need to want()
asciilifeform: ( at the very least, if range checks are enabled for ffacalc )
asciilifeform: there's an explicit range test construct, btw
apeloyee: the proper range for a cursor into an array (1..N) is (0.5 .. N+0.5); this is usually shifted to become (1 .. N+1) as in text editors, but no reason not to shift in the other direction, as you did, to (0..N)
apeloyee: (other than convention)
apeloyee: SP _is_ a cursor, I'm merely suggesting to treat it as such
apeloyee: "1) ugly" << can't see that.; "2) ... it relies on type ranges for good chunk of the proofolade"<< if you really want, can explicitly declare a subtype of Stack_Positions, omitting 0 from it
apeloyee: that _would_ be ugly indeed
apeloyee: well it'd turn a pop from empty stack into a range-dipping eggog instantly << the reason I even suggested that 3 weeks ago

ben_vulpes: shit!
asciilifeform: apeloyee: afaik it isn't possible to make types 'with hole'
apeloyee: 0 is at the boundary
asciilifeform: so what would empty stack look like , in this variant ?
apeloyee: as in my patch
apeloyee: SP=0
asciilifeform: this is not equiv to cursor behaviour in text editors, though. there, cursor always is pointing to a valid fillable cell
a111: Logged on 2018-01-17 17:03 apeloyee: the proper range for a cursor into an array (1..N) is (0.5 .. N+0.5); this is usually shifted to become (1 .. N+1) as in text editors, but no reason not to shift in the other direction, as you did, to (0..N)
asciilifeform: currently seems to me that ~all~ of the possible variants, are similarly ugly
apeloyee: what's ugly about my proposal? only two lines changed
asciilifeform: the fact that an array is indexed by a type which has a range outside of the array's.
asciilifeform: at the risk of repeating myself.
asciilifeform: ideally there would be NONE of any such thing, in the entire program.
asciilifeform: i.e. if you see an array reference, you ~know~ that it is valid, because of the type of the index.

asciilifeform: mine is also ugly, it is conceivable that somebody, some day, in a broken variant and running with -gnatp, ~will~ write to the zero cell
asciilifeform: this however is preferable than writing to the return addr on the stack !

asciilifeform: i was about to add :
asciilifeform: possibly there ought to be not 1 but... 4 null cells
asciilifeform: to carry this to logical conclusion
asciilifeform: ( i.e. equal to the arity of the highest-arity stack op )
asciilifeform: the other open q is where to draw the line re 'somebody, some day, with mutilated ffa' .
asciilifeform: because it gotta be drawn somewhere.
apeloyee: doesn't gnat have a facility to control the layout of memory?
asciilifeform: what do you have in mind, apeloyee ?
apeloyee: put a dummy array of 4 (or whatever) elements just before the Stack
asciilifeform: there is not, afaik, a way to force stack frames to be explicitly padded
asciilifeform: and at any rate the right place for such a thing is in the code, rather than in the guts of the linker
asciilifeform: pc arch also does not, unfortunately, give a way for userland to trap on reads/writes to specific piece of memory
asciilifeform: this is a fundamental headache
apeloyee: Don't Turn Off Bounds Checks.
apeloyee: and there's no problem.
asciilifeform: easy to say on 3GHz+ pc
asciilifeform: how about when it goes in a 25mhz micro ?
asciilifeform: i don't see any reason why the thing should ~rely~ on adatronicn bounds checks for correctness.
asciilifeform: *adatronic
apeloyee: it... doesn't?
asciilifeform: well right now it doesn't
apeloyee: Want(); etc
asciilifeform: ideally could somehow get rid of want() tho, AND not rely on implicit bounds checks
asciilifeform: AND be correct-to-naked-eye
apeloyee: "five-angled heptagon"
asciilifeform: or maybe not. i say it is an open problem.
asciilifeform: ftr several different items in ffa seemed to me to be 'five-angled heptagons' (starting with how to compute the asm-less addition carries) until i solved'em
asciilifeform: one way to model this process is that there is an 'ugliness budget', just like there is a cpu cycle budget, that can be 'spent' in certain ways
asciilifeform: ideally so as to maximally compartmentalize and document the ugly
asciilifeform: or for another example, take the ugliness and 'pointericity' of the traditional 'pivoting' form of karatsuba. which i killed by forcing all FZ bitnesses to be powers of 2.
asciilifeform: incidentally there were pivot-position bugs in commonly-used karatsubas as late as the early 2000s.
asciilifeform: ( prolly still are today, somewhere in ssl liquishit )
asciilifeform: apeloyee: here's another idea from my notes , that would do the job : to dispense with the array representation for the stack, in favour of linked list. ada permits the definition of a 'not null' pointer type (whose non-nullity is checked on every reference) .
asciilifeform: however this introduces explicit pointerism. ( though, i will add, NOT pointer-arithmetism )
asciilifeform: want() would then vanish; both stack underflow and overflow checks would be handled by the nullity check ( first cell has a null in its 'prev' slot; last cell in stack -- in its 'next' . )
asciilifeform: whether this is cleaner than the existing item, i will leave up to the readers, incl. apeloyee .
asciilifeform: currently it actually seems to me , to be cleaner -- in that its correctness proof is simpler, does not use arithmetic at all
asciilifeform: you can trivially show that any attempt to walk under or over the stack, would have to involve a null-dereference.
asciilifeform: nao that i think about it, it doesn't even have to introduce 'access types' ( pointers in ada ) , can use ordinary integers
asciilifeform: so a stack cell would contain not only an FZ of the current bitness, but two boolean values, e.g. HasPrev and HasNext
asciilifeform: the first cell has a false HasPrev ; the last -- a false HasNext.
asciilifeform: ( i will omit the rest of the mechanism, i think it is pretty obvious )
apeloyee: it's a wonder -gnatp doesn't disable nullity checks
asciilifeform: doesn't seem to , in gnat '2016'
asciilifeform: but this is one of the reasons why there is no escape from disasm
asciilifeform: will have to see what gets removed, what -- not
asciilifeform: the variant with booleans doesn't rely on non-nullities tho.
asciilifeform: it's simply an arithmetic-free version of want().
asciilifeform: speaking of which, could even have a stackmachine with circular ring for a stack.
asciilifeform: ( i'd rather not. but there is nothing fundamentally unusable about it )

freetlas: Wow, first time I see too many people in here :o
asciilifeform: freetlas: you did not answer the question
freetlas: asciilifeform: Just a person who likes to read trilema from time to time :)
apeloyee: from above: "Check that the actual parameters of a subprogram call are not aliases of one another. To qualify as aliasing, the actuals must denote objects of a composite type, their memory locations must be identical or overlapping, and at least one of the corresponding formal parameters must be of mode OUT or IN OUT. "
asciilifeform: apeloyee: neato. gotta wonder how this is implemented tho.
apeloyee: this is gpl gnat tho
asciilifeform: i can't picture how without a megatonne of conditionaljumps. but maybe just failure of my imagination.

asciilifeform: apeloyee: some of the 'cvsism' is deliberate -- cvs made collaborative writing harder by accident, we -- on purpose !11
apeloyee: files are NOT INDEPENDENT. despite CVS and v pretending they are. this is a problem. you could have required some form of cryptographic commitment to either the tree state or even the antedecent patches themselves, but didn't
asciilifeform: apeloyee: see the quite 'flammable' log from that thread. i put the burden of correct operation ~100% on the human operator.
asciilifeform: apeloyee: trinque and mircea_popescu would like to put more of it on the machine. i haven't with what to dissuade them, it is a philosophical q, not even technical.
asciilifeform: and yes it is entirely true that files-are-not-guaranteedly-independent.
apeloyee: do you advocate the brick "lisp machine", too?
asciilifeform: hey it's the only kind i have nao!11
asciilifeform: ( asciilifeform traded his lispm for two last-made lispm single-ic cpu... )
apeloyee: well, your point seems to be specifically that work which can be done by machine is shifted onto a human. this is insane.
asciilifeform: as i described in the linked thread, forcing the entire program under the antecedent hasher is not free
asciilifeform: it severely constrains the kind of things you can do without manual surgery
asciilifeform: so it is not correct to say 'you made the man do what the machine could do.' rather, lightened the work for operator for one kind of operation, and made heavier -- other kind.
BingoBoingo: And in other news, a police car exploded near the Brazilian border https://www.elobservador.com.uy/bomberos-explosion-auto-policial-fue-intencional-n1160744

BingoBoingo: On most days they do not explode on this side of the border.

apeloyee: that's a spurious objection. one need not to sign an antedecent state, one needs to sign a RESULTING state. to expand on http://btcbase.org/log/2018-01-17#1771900 , you're free to pick individual files from wherever, possibly several different trees, but there needs to be a tree hash in the _leaf_ patch. and it MUST match the resulting tree (under the principle that patch author takes the...
a111: Logged on 2018-01-17 19:31 apeloyee: a vpatch's purpose is twofold. 1) to provide a way to construct some files based on some antedecent files, whose hashes are given. 2) to take some responsibility about the entire tree. but the signature on a vpatch doesn't fix the state of the tree; it is defined implicitly by antedecent patches, which are liable to change at any time ("regrinding") and thereby change some files not...
apeloyee: ...responsibility for the resultant tree state).. otherwise it's unclear what one signs.
trinque: they're equivalent neh? signed antecedent state or signed resulting state + fact that the patch is signed
trinque: and in the case of signed antecedent state, don't have to press first to know if you could
apeloyee: well, a hash is not the same as the signature, but otherwise yes.
apeloyee: but there can be several of them
apeloyee: for merging
trinque: pretty obvious I'm saying signed hash, i.e. hash is in the signed vpatch
asciilifeform: trinque is right tho, they are equivalent
asciilifeform: and in both cases, the ability to explicitly mark subsystems as independent ( e.g. a readme.txt being independent from doesallthework.adb ) is lost.
asciilifeform: iirc mircea_popescu's argument was that it is wrong to say that they could ~ever~ be properly independent. and that if they could be shown to be independent, they ought to be separate v-trees.
asciilifeform: i don't have a good counter-argument to this.
asciilifeform: however it DOES mean even ~more~ work for folx using v, than ever before. and not less.
asciilifeform: potentially exponentially more.
asciilifeform: for multi-author projects, that is.
asciilifeform: for single-author, e.g. ffa, nothing really changes.
trinque: asciilifeform: to see if I can restate your opinion back to you, if I edit (as single author) both readme.txt and doesallthework.adb in separate vpatches, your view is I combine those into a single vpatch, if I want to build atop both in a new vpatch?
asciilifeform: trinque: under classical v, or trinqueian ?
trinque: classical.
asciilifeform: under classical, you can grab antecedents from any trees you want, by copying files, aha
asciilifeform: as i did in trb.
asciilifeform: so answ to trinque's q is yes
asciilifeform: !!up fromloper
deedbot: fromloper voiced for 30 minutes.
trinque: then we are closer than it appeared in the long thread. I proposed being able to name arbitrary required antecedents in a vpatch's header, and this appears equivalent in effect to copying the file in whole.
fromloper: hello
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
fromloper: it's more complete than the previously published documents on the Ivory
asciilifeform: fromloper: pretty sure i've seen this before
fromloper: there were older versions of three chapters from this documents on Bitsavers, but not the whole thing
apeloyee: point is, the situation when you can replace one of the patches with figurative "format c:" and 'v' will be none the wiser as long as the file is not touched by later patches is insane
asciilifeform: fromloper: it is not a complete arch description, you cannot write a working emulator with it ( or even make the existing snap4 not-crash )
asciilifeform: fromloper: i'ma look. ty
fromloper: did you succeed in scanning the chip at Zeptobars?
asciilifeform: apeloyee: there is not a mechanical solution to preventing someone from 'putting in format c:' proverbially
asciilifeform: fromloper: that was phf's plan. afaik he has not, as of yet.
asciilifeform: fromloper: i shopped around in commercial labs; the best bid was in the neighbourhood of 25,000 usd.
apeloyee: when you sign a tarball, the signature is not transferrable to anything else
asciilifeform: fromloper: that's where it stopped. i do not have 25k usd to use on ivory die photo.
asciilifeform: apeloyee: observe , i do not actually disagree .
fromloper: I see, hopefully phf will have more luck with Zeptobars
asciilifeform: apeloyee: trinqueian / mircea_popescuine vtron is arguably The Right Thing. my observation is that it may be a 50kg sword.
asciilifeform: fromloper: i only have two 'ivory' chips, and ideally would like to leave one intact , for active test . iirc phf also has 2 to use.
asciilifeform: so i'ma save mine for proper commercial lab. but that means potentially forever. maybe whoever takes it off my corpse, can get it photo'd.
apeloyee: "may be a 50kg sword" << doesn't seem to be. can be retrofitted into an existing design. as i said above "there needs to be a tree hash in the _leaf_ patch. and it MUST match the resulting tree"
asciilifeform: retrofitted yes
asciilifeform: but i am speaking of ~use~.
fromloper: asciilifeform: if I remember, you wanted to hook this intact chip to some emulation of Ivory's life support
asciilifeform: fromloper: correct
asciilifeform: fromloper: currently however i do not even know where the power supply pins are, much less bus addressing, i/o, clock, etc
asciilifeform: or the necessary timings.
asciilifeform: ( or what it expects to find on the bus, or almost anything else )
asciilifeform: i do not have, nor ever had, a working 'ivory' of any description.
fromloper: VLM is not very informative for this purpose, unfortunately
asciilifeform: fromloper: correct. almost totally useless.
apeloyee: I proposed being able to name arbitrary required antecedents << also probably needs a mechanism to declare "there are no other files in the tree"
asciilifeform: apeloyee: look at the trb tree, and picture what the mass of the patches would have been, if this requirement had been in effect when i made it.
asciilifeform: ( and yes mircea_popescu's answer was 'shuddup and suck it' . which is very easily said when you ain't the one sucking it )
asciilifeform: fromloper: i'll confirm, this is a larger and moar detailed document than old one.
apeloyee: a hash of the entire tree doesn't take much
fromloper: at the very least, the description of the instruction set is much more complete, all the opcodes are listed and no blanks at all
fromloper: there is a whole section on the virtual memory
fromloper: though it's still an early version of the architecture, revision 0 if I understand correctly
fromloper: the last one is rev 5
fromloper: which was designed for VLM exclusively
fromloper: asciilifeform: I have noticed that some of the former Symbolics employees are fairly active on Twitter, like https://twitter.com/swmckay (one of the developers of VLM) and https://twitter.com/KalmanReti , do you think it is possible to pry any information out of them?

asciilifeform: thinkingmachines co was another such. died same way.
asciilifeform: there is an entire graveyard of these; it simply so happens that i am only interested in the lispm-flavoured ones
asciilifeform: ( where i know for a fact that they Had Something )
asciilifeform: for all i know, the one and only path to e.g. a room-temperature supercon, was found at one of the reagan scamola firms, and died with it, also. i simply do not know about it.
fromloper: I also wanted to ask, did you figure out how to launch NS in VLM? I'm getting some Xlib error when I try to
asciilifeform: i suspect that the copy on the Official genera disk, never worked.
asciilifeform: but i never tried it under alpha, gotta try.
asciilifeform: and iirc phf has a working ivory -- worth trying there also
fromloper: I wonder if it's going to ask for a license key like Macsyma on the same disk does
asciilifeform: there is, theoretically, a working disasm
asciilifeform: fromloper: in re ivoryology, another unknown is the fep. virtually nothing is publicly known about the fep.
asciilifeform: ( for n00bz to the subj -- fep was an entire comp, mc68k, embedded inside bolix lispm, handled i/o and certain aspects of eggogology )
fromloper: Ivory still has mc68k?
fromloper: in its FEP
asciilifeform: afaik the standalone ones, did
asciilifeform: the 'macivory' did not, used a proggy running on the mac.

asciilifeform: fromloper: i actually do not know anything re who, if anyone, maintains. aside from phf's admission to having a private fork, linked above.
asciilifeform: ( last i knew, phf did not publish his changes )
asciilifeform: i do not know why not.
asciilifeform: this is a q that only he can answer, supposing he feels like answering.
fromloper: well, he doesn't for some reason
asciilifeform: re fp, i'll observe that bolix used a weitek fp unit
asciilifeform: similar in fact to the one in everybody's old 486
asciilifeform: and that if emulator's does not behave exactly same -- it will lead to barf, yes
asciilifeform: and who even knows if weitek is fully documented somewhere.

asciilifeform: fromloper: currently i suspect that many, possibly majority, of serious bolix collectors, ~do not want~ there to be an accurate emulator.
fromloper: I've read the whisperers discussion here, seems to be plausible
asciilifeform: i -- want. and this is why by and large they do not talk to me. they know about my www, they knew where to find me. they also know that i will publicly and immediately leak any bolixologial document that i am given. and want to make emulator. and for this, i suspect, they do not talk to me.
asciilifeform: this is a hypothesis. so far my best one.
asciilifeform: some people spent $10k's on their collections of bolixiana. and imagine that these will become worthless if an accurate fpgalogical emulator appears. and for all i know , this is true. i simply don't care.
asciilifeform: the ones who hoard secrets because they imagine that they have a ticket to being part of some future commercial revival of bolix, however -- those are idiots.
asciilifeform: there will be no second coming of commercial bolix.
fromloper: I'm curious what John C. Mallery intends to do with his property, other than collect support cheques

asciilifeform: and when he dies they will pay for his sons' yachts. etc
fromloper: Kalman Reti said 4 years ago: "The problem is that the Symbolics IP is now owned by John Mallery; he has stated he has plans for making it available but so far (several years) has not yet done so."

asciilifeform: but if i were designing asic -- yes, would use.
asciilifeform: and weste's , too. it seems to contain many usable goodies for asicist.
asciilifeform: unfortunately i do not have any way to make asic. as for fpga, none exist of the necessary size. ( see e.g. http://btcbase.org/log/2018-01-04#1764242 )
a111: Logged on 2018-01-04 20:06 asciilifeform: in other 'news', it is apparently impossible to fit even ONE 4096-bit adder into an ice40-8k ( the largest in the series )
amberglint: asciilifeform: do you know what this language is? http://users.rcn.com/david-moon/MMD/MMD.lunar looks like Moon's own invention
asciilifeform: seemed to me, to be an infix lisp, sorta like 'dylan'
asciilifeform: ( why he did this ? i do not know )
amberglint: he renamed it to Lunar, apparently
amberglint: no one else seems to know or care about it, judging by google's output
asciilifeform: i read the linked manual in '08 and will admit that i did not find it very interesting. it is the same kind of dead end as dylan.
asciilifeform: ( and if anyone began to use it, would prolly end as same kind of catastrophe as e.g. ruby . )

asciilifeform: 'The registered office of Cardano Foundation is: Cardano Stiftung, Gubelstrasse 11, 6300 Zug, Switzerland.' classy.
