asciilifeform brb, tea
asciilifeform: diana_coman: plox to briefly describe how you set up this build, so i can replicate locally
asciilifeform: clear so far; but not why
asciilifeform: hrm.
asciilifeform: the 2nd eggog is also a constraint eggog, thrown in bottom of http://p.bvulpes.com/pastes/YUqze/?raw=true
asciilifeform: ( or moved during the build ?? )
asciilifeform: diana_coman: 'Error detected around a-calend.adb:801:11' >> http://p.bvulpes.com/pastes/fCaiF/?raw=true << is there any chance yer clock is off ?
asciilifeform: ( presumably he deleted ? )
asciilifeform: i didn't even see any mention of 'crypto', other than a 2017 piece where he gripes about uninvited js minerism
asciilifeform: ( aside from pro virii-bakers , for tests. but d00d dun seem to be 1 of ~these~ )
asciilifeform looked at linked www, seems to have.. buncha reviews of winblowz av!! who the fuck ~collects~ winblows av?!
asciilifeform empties head.
asciilifeform: aite.
asciilifeform: mircea_popescu, diana_coman do you have any pressing itches re the asm vivisections , or can table it for nao ?
asciilifeform won't be surprised if 1 day we learn that it only happens if you click on the bottom serif of a lower case 's' or somesuch
asciilifeform: ( does that thing invoke rng somewhere?! )
asciilifeform: all the moar headachy
asciilifeform: grr couldn't reproduce 2nd time
asciilifeform won a http://trilema.com/2014/the-all-american-asshole-in-his-own-words-with-my-own-notes/ in trilemalotto today. classic piece, but observe that clicking on the 'internal' footnote linx throws the selector script into same bug as on asciilifeform's site
asciilifeform: sysop kicked the drum disk to get it goin'.
asciilifeform: asciilifeform's brother worked on 1, in '90 or so. thing powered a hall of 32 glass terminals , occupied ~24/7 by hungry undergrads
asciilifeform: ( or boot sysv unix, if yer a masochist )
asciilifeform: 4MB aint enuff to e.g. trb inside. tho 1 could rsa in it.
asciilifeform for yrs nao has wanted to build some boxen around sovok k1801, but was never able to justify the sweat in light of war effort -- the demand for iron wallets and similar , even among folx with 3rd eye open, seems to be pretty minimal.
asciilifeform: i would almost say 'i had moar fun with that thing than ever did with pc', but this is prolly http://btcbase.org/log/2019-01-18#1888232 -effect. ☝︎
asciilifeform can see it..
asciilifeform: 'hand me down' from elder.
asciilifeform was given 'mk61' at same age i think diana_coman's kid is nao ☟︎
asciilifeform: ( before mircea_popescu answers 'holy mother of fuck, this is chemically-pure wankery' -- yes, it was. but imho still beats shit out of redditism. )
asciilifeform: for folx who dun ru -- eggogs had 'depth', which referred to how many ops you persisted with after already eggoging
asciilifeform: and all cuz the folx at 'angstron' didn't have laser, like intel's, to snip off the defective chunk of the ic on conveyor, lol
asciilifeform: on that 1 calc
asciilifeform: contains such things as 'beasts', 'werewolves', 'darkness' , 'monsters', all named 'effects'
asciilifeform: https://pmk.arbinada.com/node/12 << for the troo aficionado.
asciilifeform: one could actually ffa on that ( if somehow find one ! )
asciilifeform: very decent chip, btw, 150,000 16-bit multiplications / sec., and addressed 4MB.
asciilifeform: ( interestingly, still produced! at privatized 'angstrom co', but not sold to humans afaik )
asciilifeform: in ru there are some decent microscopists ( not the 1 phf went to, but apparently others. ) for instance, very recently found that К1801 ( sovok 'pdp-11' single-chip ) was ~not~ in fact a photoclone of dec's (only the early '80s demo ver was!) but , turns out, entirely indigenous orc design, with coupla x ~fewer~ transistors and yet faster max clock ☟︎☟︎☟︎
asciilifeform: ( surprise ? they had smt pcb in sovok )
asciilifeform: http://www.artem.ru/calc/2.jpg << subj is under the large white paint stain.
asciilifeform: ( and think, that was a ~hand-drawn~ chip, with coupla thou. transistor. )
asciilifeform: this sorta thing happens to this day.
asciilifeform: so produced garbage ( but ordered!111 and therefore fascinating!111 to certain folx ) garbage. ☟︎
asciilifeform: what found, was that the 'eggog instrs' were meant to be various floatingpointisms, that didn't work out in the last chip revision, and so left out of the manual
asciilifeform: but for 30 yrs the aficionados had nfi what thing actually did when eggoged. until microscopist.
asciilifeform: much noise was made re the peculiar results of running various
asciilifeform: i.e. exploring undefined instructions
asciilifeform: ^ ancient sovok programmable calculator. had entire subculture, of , among other things, 'eggogology'
asciilifeform: !#s mk61
asciilifeform: but requires a bit deeper cut than 'i'ma run $snippet and time'
asciilifeform: and it's exactly what asciilifeform intends to do to e.g. the bolix.
asciilifeform: with thinking, rather than brute force ( nobody will live to see even 2^128 bit of phase space walked via brute force, do the arithm )
asciilifeform: also did not say that profiling is useless, profiling -- worx, and is a must for anyffin where you actually give a fuck re performance. but what we aint got on pc, is anything like an actual grasp of wtf the thing does and precisely why.
asciilifeform: which is not to say that you can say ~nothing~ -- can say many things (e.g. the point re the reorder lock, stands for all current x86 irons)
asciilifeform: it aint a z80, thing is finite yes, but coupla MB of state .
asciilifeform seen many times
asciilifeform: and then you pick up chip made on a tuesday, and it has diff mechanics than what they sold on wednesday of same wk.
asciilifeform: mircea_popescu: it's a stateful box of ??? ( rumour is, not even orig vendor can fully describe the phase space )
asciilifeform: it's a shit arch.
asciilifeform: yer talking to 1 of the few remaining. (and perhaps only because asciilifeform dun often asm , knows measure)
asciilifeform: this is why most 'i'ma do it in asm!' folx by nao have drunk to death.
asciilifeform: for no describable reason.
asciilifeform: eh and then you make your case switch 4-legged instead of 3 somewhere, and all readings change.
asciilifeform: they also dun do much good! if i had a wood furnace, i'dve stoked it with'em by nao
asciilifeform actually has the manuals, intel's and amd's, they eat a good bit of shelf
asciilifeform: i.e. when introduced reorderism & pipes.
asciilifeform: they haven't printed 'tick table' since old pentium.
asciilifeform: mircea_popescu: manual is silent, for the most part, on subj.
asciilifeform would really instead like a cpu where erry instruction takes 1 tick, fuck errything. but presently dunhave.
asciilifeform: for all i know, not even a computable function, lol
asciilifeform: ( the rub is that ticks depend heavily on context, on a reorderistic cpu )
asciilifeform would kill for an accurate tick table for opteron. but none exists ( possibly when i have msdos gnat, can bake one..)
asciilifeform: i was answering q of 'why does gcc put out this odd form for a computed goto'.
asciilifeform: ( it's make a serious diff inside an inner loop, but here we have it in exception handler, which aint )
asciilifeform: mircea_popescu: the 'test' vs 'cmp' thing is microscopic , so arguably red herring here
asciilifeform: ( based strictly on diana_coman's output )
asciilifeform: seems like the diff only comes into play when there is 1 or moar ?
asciilifeform: aha
asciilifeform: ( zcx on left hand, ljmp on right )
asciilifeform: e.g. for 3 handlers, 3 | 1.329 | 446.821
asciilifeform: mircea_popescu: do i misread the http://btcbase.org/log/2019-02-14#1896636 run ? ☝︎
asciilifeform: ( btw the obj reason why none of this is visible in ffa -- there aint any tasks! so even in ljmp mode it shits out same coad )
asciilifeform: diana_coman does seem to have crafted a testism where it does
asciilifeform: ( recall, we're on a reorderism arch )
asciilifeform: whereas if you didn't touch it, it then is
asciilifeform: mno, if you lock the pipe, you lock the pipe, that reg aint available for reorderism
asciilifeform: hm so which 'not anymore' ?
asciilifeform: (so it actually locks the pipe and waits for both operands to become available)
asciilifeform: think, cmp can only work by subtracting
asciilifeform: test simply ORs the bits in register together (and this happens by default when you load it, cuz it's costless electrically)
asciilifeform: cuz it does a subtract, see
asciilifeform: mircea_popescu: opposite. cmp is ~3x slower than 'test'
asciilifeform: whereas here..
asciilifeform: on sane people planet i could determine this by reading the motherfucking docs
asciilifeform: and precisely why slower (and where even slower)
asciilifeform: i sawed it open to try an' see how thefuq the longjmp thing actually worx
asciilifeform: nuffin yet, afaik
asciilifeform: at least where routine appears in a task
asciilifeform: zcx hands-down moar compact
asciilifeform: lessee..
