mircea_popescu: if they had fully qualified descriptors instead of "filename" it'd be all rosy ?

mircea_popescu: (note that the tempting "obvious" approach -- describe foo then!!! -- is not only fucking broken, but broken in the exact way minsky wasted life trying to produce. there can not be ~description~, the only way to induce meaning in the machine is through filiation. v-produced foo has a very strict "wtf is it ??" answer associated, but also very fine and not structure-driven.)

mircea_popescu: you can not in fact define symbols after the fact (and i don't mean just the elf technical term -- all symbols). the only way to define a symbol is by its parents.
mircea_popescu: asciilifeform yes, but you see it as an improvement because you perceive it forces their hands down the right path, whether they want to or not. it's a rapeprovement.
asciilifeform: the infestation is deep enuff that you quite obv could not make above example actually build reliably on any extant unix. the entire notion of 'portability' as pictured by unixtards (i.e. powered by #ifdefism) precludes it.

asciilifeform: i'm surprised answer wasn't '1'
diana_coman: mircea_popescu, I'm not aware of anything that actually does that reliably
asciilifeform: as i understand, it cannot be done reliably on a unix, period.
mircea_popescu: diana_coman myeah. i guess it'd take a patch on gcc, which is too much hassle atm.

mircea_popescu: they themselves admit 2mn is an upper bound, BY WHICH TOKEN they themselves admit the complification was spurious.
asciilifeform suspects that the '2mil' figure they got from 'how many in kernel 2.6 and let's times three' or similar
mircea_popescu: quite likely.
mircea_popescu: well, either that or they o(N) + n log n for some values of N, n.

mircea_popescu: are you discussing the specific case of grep there ? because i do believe it's a sound tradeoff.
asciilifeform: it's 'sound tradeoff' until it aint (e.g. you have system where 'allcomers' can trigger a grep on a data set they crafted, and yer box grinds to a halt )

mircea_popescu: " /* Take care to ignore link-once functions that were removed. In these cases, the function address will be NULL, but if the encoding is smaller than a pointer a true NULL may not be representable. Assume 0 in the representable bits is NULL. */"
mircea_popescu: why the fuck would you use encodings SMALLER than the bus width ?!
asciilifeform: antediluvian os (e.g. tops-10 et al) at least had hard limits printed in manual
asciilifeform: rather than pretense of 'infinite'
mircea_popescu: and why would you assume what broken notation means.
asciilifeform: bonus: 'null' aint 0 on any extant box.
mircea_popescu: right ?!

mircea_popescu: why not pick FB.
mircea_popescu: i mean, FB and 00 are equally likely to be fragment of null pointer.

mircea_popescu: zcx doesn't work, sjlj is broken and glibc is beyond salvation.
mircea_popescu: asciilifeform the issue is to come up with a linking scheme we can actually use.
asciilifeform: mircea_popescu: unless i misread bvt's piece, the bugola is only triggered when tasks are permitted to terminate.
mircea_popescu: yeah ?
mircea_popescu: "house only explodes when you turn on water faucet" is not an answer here.
asciilifeform: so consider what the airplane people do. they dun terminate. instead populate with N threads, where N is the # of physical cpu, and they can idle or work as demanded.
asciilifeform: this btw is how asciilifeform implemented phuctor backend.
mircea_popescu: cute, but not useful. we gotta have a programming environment, not a programming cardboard.
asciilifeform: mircea_popescu: 'house explodes when i turn on the hydrogen faucet' 'why do you have a hydrogen faucet ?'
mircea_popescu: we do not agree.
asciilifeform: mircea_popescu: the real q is , what subset of the claimed extant functionality adds up to a programming environment.
asciilifeform: ( i.e. working subset )
mircea_popescu: we're kinda discovering by doing here. but user-controls-machine is certainly in there.
asciilifeform: this is factually not the case on unix tho. good % of the control is illusory ( see e.g. the zombie thread )
asciilifeform: or the 'seppuku of son'
asciilifeform: what we did, is to poke with awl until punctured some of the illusions.
mircea_popescu: i intend to approach hardware breakage at hardware level.
asciilifeform: that's asciilifeform's tack.
mircea_popescu: something like "keep two of everything and throw out anything that behaves in any way contrary to your illusion no matter what happens".
mircea_popescu: is a good start.
mircea_popescu: i find it works fine with people ; and it'll work doubleplusfine with hardware. let it adapt to my needs or die.
asciilifeform: it worx great with hardware. except when it's connected like on pc, where 1 hosed device can fandango over entire ram. or handled as on unix, where i/o will happily zombie out on unplugged $gadget etc
mircea_popescu: so it'll come to more boxes, whatever.
mircea_popescu: the principle ain't changing to fit the world.
mircea_popescu: s.mg is perfectly willing to eventually erect torture chamber where shamed boxes ritualistically destroyed for their sins.
asciilifeform: this is how the 'cloud' people ended up with their circus. 'pc is broken' 'what if you connect 9000 pc'
asciilifeform: mircea_popescu: i'm sitting in something quite resembling such chamber as we speak.
mircea_popescu: proof positive method works!!!
asciilifeform: to revisit orig upstack thrd : pc dun offer iron locks. so threading relies on software locks, that 'work' in the sense where gcc is relied on to shit'em out correctly. what bvt appears to have found , is that (under particular inputs) it doesn't.
mircea_popescu: so leaving hardware alone, "zombie thread because northbridge went south" etc -- we still need a linking scheme that works.
asciilifeform: this is theoretically fixable. the sad part tho is that gcc is a potentially ~bottomless well of these.
mircea_popescu: well, could also link against musl, ban glibc
asciilifeform: that was settled in 2015 iirc.
asciilifeform: glibc has 0 biz in tmsr proggy.
asciilifeform: quite obv, any fix will have to fix musl.
mircea_popescu: in any case, this is a major decision / inflexion point, and we truly need all hands on deck for this, i'm not equipped with the right chicken darts to throw at guts / read feathers thereof.
mircea_popescu: so is basically the idea what we want is to get sjlj to work on musl for ada proggies ? or what ?
asciilifeform: ( half the reason why asciilifeform dug out musl, is that it's compact enuff to be fixable, at least in principle )
asciilifeform: mircea_popescu: it already worx , afaik, on musl, ave1's gnat shits out strictly musl-static linkage.
asciilifeform: but remains to be established if bvt's bug afflicts it.
mircea_popescu: some time to look at things and consider matters will be needed ; but i specifically want to hear something from asciilifeform ave1 bvt diana_coman phf spyked trinque
asciilifeform: mircea_popescu: the diana_coman-bin we disasmed yesterday , is musltronic.
asciilifeform: as is all current test build of ffa, etc
mircea_popescu: asciilifeform yes. but to my knowledge to date musl was a preference rather than a standard. we never said "no more glibc linking" as we said eg http://btcbase.org/log/2018-09-19#1851879 ☝︎
a111: Logged on 2018-09-19 17:47 mircea_popescu: but anyway : NO NEW WORK ON SHA PLOX. USE KECCAK.
asciilifeform: mircea_popescu: imho the near-term thing to do is for bvt to get the gcc5sim, glibcism, out of his test setup. then can proceed to fix bugs that we actually have in the house, rather than liquishit that only afflicts glibctards.
asciilifeform: mircea_popescu: we did. recall the 'nss' incident.
mircea_popescu: link ?

asciilifeform: mircea_popescu: this was a ~3 month thread
mircea_popescu: ok but you're breaking form here.
asciilifeform: i dun think anyone's compressed it into a compact chronology of yet
asciilifeform: ( possibly nicoleci job ? )
mircea_popescu: yes, no glibc was in fact a preference, and we got it out, of trb, of eulora, etc. no argument there.
asciilifeform: and out of gnat.
asciilifeform: ave1's entire project.
mircea_popescu: nevertheless, we never actually said "do not use this".
asciilifeform: glibc is simply poison.
asciilifeform: ( e.g. 'bash bug', also drepper , also via glibc )
mircea_popescu: anyway, this can rest nao,
asciilifeform: item is ~10x the mass of musl, and fulla 'surprises' that erry time turned out to be architecturally baked in.
mircea_popescu shall give it some time to hear from people.
asciilifeform: aite

a111: Logged on 2019-02-12 23:41 asciilifeform: there's a lulzy 'pentagon standard' one, the name presently escapes me, iirc it is in the log tho
asciilifeform: mircea_popescu: ... nor is this the only instance of this kinda thing. consider e.g. https://archive.is/MxPlA#selection-14.407-2653.3
asciilifeform: they didn't include a word x word mul that gives you both halves. why not ? 'oh not all irons have a mul instr.'
asciilifeform: or 'can haz carry from add?' 'no, cuz not all irons HAVE carry flag'
asciilifeform: it's an elementary babel.
asciilifeform: asciilifeform's 1st step in writing ffa, recall, was to conceive of (and prove) an arithmetic workaround for above. that, right off the bat, cost ~10fold cpu.
asciilifeform: ( and when found that ~despite this~, http://www.loper-os.org/?p=2906 , was pant-shittingly hilarious, how koch still managed to be the tortoise in the race )
asciilifeform: this is rather like if 2 d00dz run, and the 1 carrying 100kg of lispmachine ends up winning.
mircea_popescu: anyway, let's draw some quick possible approaches here.
mircea_popescu: a. we make no standard, every man for his own, but : a.1. ada is the preferred language ; a.2. musl is the preferred standards provider ; a.3. zcx is the preferred exception mechanism ; a.4. static is the preferred build mode. this should come with a design process for candidates evaluation for standardization.
mircea_popescu: b. ada-sjlj-musl-static is the standard, and we simply don't sign or use anything that doesn't live up to this.
mircea_popescu: c. ada-?-musl-static is the standard, either zcx or sjlj is acceptable (mostly based on what threading philosophy one embraces), with an obvious preference for zcx if one doesn't thread.
mircea_popescu: d. ada-zcx-musl-static is the standard for non-threaded programs, we don't standardize threading.
mircea_popescu: e. something else (among which possible e.1. someone reads and implements dwarf properly ; e.2. someone picks a glibc to grandfather and dedicates himself to cleaning and fixing.)
asciilifeform: re 'e', i can't picture what'd move anyone with two neurons to rub together to maintain a glibc, that'd be rather like starting a trb from prb 12 (or what is current one)
mircea_popescu: can import glibc 3.x or w/e.
asciilifeform: i dun see where drepperism wins in ~any~ version, vs. the ab initio and 10x moar compact musl.
mircea_popescu: asciilifeform current one prolly v49, note how gcc went from 5 to 8 in 2 years.
mircea_popescu: asciilifeform but it's not you who has to see, maybe someone sees, what. im certainly not sending you to e.2
asciilifeform: mircea_popescu: cuntoo is arguably a realtime test lab for 'what does removing glibc from ~errything~ cost'
asciilifeform: for instance, emacs has yet to be cured, as i understand
mircea_popescu: so it is.
mircea_popescu: asciilifeform i very much don't expect you want the prb 12 that is emacs. rewrite yes ? :D
asciilifeform: 'd' is arguably mis-statement of problem, a threadless proggy incorporates ~neither~ system
asciilifeform: ( as asciilifeform recently discovered re ffa. it dun thread, and gcc correctly snips out all pertinent coad )
mircea_popescu: asciilifeform still gotta build the ada environment ~with something~.
asciilifeform: environment yes.
mircea_popescu: it was short form for that.
asciilifeform: aa
asciilifeform: given this, asciilifeform would go with 'b' + 'we fix the breakages , both as-we-find-'em and proactively '
asciilifeform: rather than continuing in a babelized gnat with 'pick yer threader, pick yer stdlib' etc
mircea_popescu: this pretty much bans glibc, from my unexpert cursory look it dun seem fixable for sjlj.
asciilifeform: i banned it for all asciilifeform-powered efforts in 2015, and dun miss it.
diana_coman: re glibc: until now I saw it as tolerated until full tmsr version (whatever that might be, i.e. owned glibc version or musl or whatever)
mircea_popescu: diana_coman looks like it's going the way of cuntoo-ada-musl, no glibc.
asciilifeform: diana_coman: the caveat is that i still dunhave a working cuntoo for all asciilifeform-operated irons; e.g. rk is still running barbaric old glibc gentoo
diana_coman: it does seem precisely so, yes
diana_coman: and asciilifeform beat me to it
mircea_popescu: asciilifeform getting an aarch64 musl sjlj going will be a fun task.
diana_coman: that's precisely why it was tolerated until now afaik: because all sorts not yet fully ported to anything tmsr
asciilifeform: mircea_popescu: entirely. see 2d ago thrd.
mircea_popescu: aha.
mircea_popescu: (on both counts, lol)
asciilifeform: i expect that i'm even doomed to open a book and see how the fuck arm64 worx.
asciilifeform: mircea_popescu: fix of sjlj on arm64 is actually moar urgent than arm-cuntoo, cuz sanely build ( static-musl ) ~will~ run on glibcistic linux
mircea_popescu: possibly, yeah.
asciilifeform: ( asciilifeform is for instance at this very moment sitting on a glibcistic gentoo box, but where all tmsr soft is musltronic )
diana_coman remembers that eulora client is 99% NON-tmsr
asciilifeform: diana_coman gets the trooly hard nuts to crack ( which is why retained by s.mg for coin , neh )
asciilifeform: ( asciilifeform also maintains multi-MB 'non-tmsr' proggies. for orc dubloons. it's how he eats )
diana_coman: to my mind option b has the benefit that it concentrates the effort in the right direction at least
asciilifeform: ( the less said on the subj, the better, tho, my appetite already ruined by thinkin' about it )
asciilifeform: diana_coman: if it aint a seekrit: didja ever try building client on musl ?
diana_coman: asciilifeform, honestly, all I wanted was this game! lol
asciilifeform: heh
diana_coman: asciilifeform, no, but obv I will have to not try but do it
asciilifeform: rrright, was curious re the volume of barfola
asciilifeform: ( e.g. asciilifeform was quite surprised when found that trb and ALL deps built cleanly & functioned on static musl )
asciilifeform: with ~0 modification
diana_coman has no curiosity on the topic: all pain at its time, not earlier
asciilifeform: fair'nuff
diana_coman: I don't know about option c i.e. whether there is something lost by going with it
diana_coman: I guess the main thing against it would be that part where can't kill
asciilifeform: diana_coman: the 1 use case i can picture for zcx, is on ultracompact irons. but even there, really, are we gonna use a http://btcbase.org/log/2019-02-12#1895612 somewhere ?! ☝︎

mircea_popescu: also, subtle point in http://btcbase.org/log/2019-02-17#1897708 bears belabouring : the point is to standardize ~the tools~, not necessarily (in order) their usage, or end products. the idea is for user to know what to expect if builting a tmsr box, and why he expects that, not necessarily what he can do with it. ☝︎
a111: Logged on 2019-02-17 16:10 mircea_popescu: asciilifeform still gotta build the ada environment ~with something~.
mircea_popescu: he can use it to crush hymenoptera for all i care, just as long as it contains the correct set of software.

asciilifeform: possibly i oughta add the detail, that $item is like any other machine i/o-ism -- on bare irons, it writes to the irq table ( whatever shape that has on $irons ) , on unixen it yes uses signals, because wtf else can you do there, on (hypothetical) msdos gnat, will again write to irq table, on boxen without interrupts -- will give eggog on build, what else; etc
asciilifeform: ( incidentally, when asciilifeform speaks of 'iron babel', interrupts are a screamingly concrete example : there is ~no uniformity b/w archs re how they're implemented (does it save regs ? which ? what happens if two interrupts temporally near ? ) or how many , or for what devices, etc )
asciilifeform: old msdos hands will recall setting jumpers for e.g. 'soundblaster' irq etc
asciilifeform: and conflicts.
asciilifeform: this was 'fixed' by intel (with obscene amt of direct standard authorship by microshit) by making the controller 9000x moar complex
asciilifeform: aka 'plug and pray'
asciilifeform: 'younger' archs that were baked with decent # of interrupts to begin with, have ~slightly~ less retarded subsystem
asciilifeform: afaik none of'em, however (with possible exception of sgi's) have semantics such that multiple processors dun share a bottleneck at the interrupt controller
asciilifeform: ( ever wonder why cannot make 'unhangable' os for multi-cpu pc ? this is why )
asciilifeform: all of this might seem uninteresting until you realize that this is what sits under all threading, no matter how implemented on os side.
asciilifeform: ( the very need for locking, on software level, for instance, comes from the absence of any sane mechanism for corralling data to particular cpu )
asciilifeform: concretely -- on sane iron, cpu do not share memory, but instead implement exactly diana_coman's work-queue mechanism.

mircea_popescu: keks
mircea_popescu hasn't even the faintest who dood even was
BingoBoingo: Apparently a UStard seriously underestimating what he paid in total taxes
BingoBoingo: Anyways, All these names that had burned out completely before I showed up a few months later. History!
asciilifeform: mircea_popescu: by far biggest 'layer of c' is : the kernel.
mircea_popescu: true.
mircea_popescu: i suspect ada machine can be made with much tinier kernel tho.
mircea_popescu: so do you.
asciilifeform: i'm still curious what mircea_popescu thinks of as 'ada machine'
mircea_popescu: me too.
asciilifeform: heh
asciilifeform: BingoBoingo: http://pizarroisp.net/2019/02/17/pizarro-isp-february-17th-update/#selection-53.0-53.109 sounds interesting
asciilifeform: is this actually in the worx ? or still chalkboard
asciilifeform: mircea_popescu: thinking about it, kernel is really the starting point for 'get c the hell off the box' -- the e.g. 20% of gnat's standard lib that's in c, is in c strictly cuz of reason illustrate in http://btcbase.org/patches?patchset=udp , i.e. that kernel api doesn't eat sane (e.g. bounded array) parameters, demands liquishit c-istic buffers
mircea_popescu: entirely possible we'll have to do kernel-and-rest in one gulp
asciilifeform: seems like it.
mircea_popescu: though if possible, i'd just move the wrappers to ada first.
mircea_popescu: one advantage to c's retardation is that well... as long as you feed it the shit it expects, it'll work in the same manner as before.
asciilifeform: i linked the udp thing for a reason -- wrappers inescapably look like 'chunk of c', cuz headerola.
BingoBoingo: asciilifeform: I'm "knocking" on a few doors. The "polite way" hasn't been very productive, so the rapeful way is appearing very necessary. Haven't hear anything from the "Proud Boys", excess of ego appears to be a defect of the dwindling population of forum operators.
asciilifeform: BingoBoingo: mircea_popescu did say.
BingoBoingo: asciilifeform: Indeed
BingoBoingo: A large number of the folks who did or in the past would have started a forum are in the Google/Youtube hugbox or similar "watermelon farms"
BingoBoingo: Bizarre Characters gotta wank it
asciilifeform: mircea_popescu: the other major chunk of c, is of course the gcc backend.
asciilifeform: ( gnat dun have own back end, and afaik never did )
asciilifeform: y'know, the part that actually pisses out e.g. x86 instrs.
asciilifeform: ( locking bugs & all )

BingoBoingo: <asciilifeform> i'm still curious what mircea_popescu thinks of as 'ada machine' << 128 bit MIPS 1, 2, 8, or 72 cores at 800, 1600, or 3200 mhz when purpose backed. Otherwise 128 bit for the UCI address space.
BingoBoingo: That's all I've got to guess atm
mircea_popescu: myeah.
mircea_popescu: actually ada not having a backend can (and probably will) hide all sorta surprises.
asciilifeform: funnily enuff, i suspect there are a grand total of ~two~ ada back ends in existence : 1) the Official adacorpse one , sewed out of gcc ( the 'fsf gnat' is simply old copy of same )
asciilifeform: 2) bolix's
mircea_popescu: except latter only works for their own iron.
asciilifeform: could propose that there is a (3) , if one of the closed $maxint winshit adas actually implemented own, rather than stealing gcc's
asciilifeform: but i suspect ~those~ are all stolen gcc inside.
mircea_popescu: seems probable.
asciilifeform: mircea_popescu: potentially retargetable. but currently nfi if this is a useful shortcut to 'bake a backend'
mircea_popescu: myeah.
asciilifeform: at the very least, theirs is 50x moar compact than gcc.
asciilifeform: (i.e. ~readable)
mircea_popescu: problem with all this is -- the option's always between trust and knowledge. since we've discovered we can't trust gcc, it follows not only that we now have to write our own ; but that we must maintain the people who know how to write one.
asciilifeform: ( for n00bz: ) writing a compiler back-end aint actually hard. asciilifeform & many many other folx, did it ~as homework~ , at school. the hard thing is writing a ~decent~ optimizing backend.
asciilifeform: it's why ~errybody is using gcc's (incl. the folx pretending not to)
asciilifeform: the other thing that makes backend a bitch is that ~100% of the work has to be done again and again, for each iron.
asciilifeform: ftr much easier for a sane iron ( with small instruction set ) like mips, than for x86.
asciilifeform: re bolix back end, i suspect it aint very useful as starting point, because was far ~too easy~ item , in that the iron per se was sane (i.e. performed bounds and type checks, so much of what gcc is stuck doing in soft, was unnecessary )
asciilifeform: if we had a sane iron, would be similarly easy to produce a back end ( and that's what asciilifeform thinks of as 'ada machine' )
asciilifeform: but presently we haven't such.
asciilifeform: ( this is where i point out, that the fabled 'sane iron' isn't simply a purely aesthetic win to ticke asciilifeform's aestheticles, but in fact substantially cuts down on the complexity of ~all other sane items~ that are to stand on top of it )
asciilifeform: *tickle
