asciilifeform: but indeed, homogeneous matrix of cells buys you 'hdd-like' item, where it is not necessary for whole thing to work
asciilifeform: this'd have the obv. down side, that your prop. delays are not deterministic. but would be cheap.
asciilifeform: you map'em out, like 'bad blocks' on '80s hdd☟︎
asciilifeform: mp_en_viaje: on anyffing at all, you get the 'only n % gotta work'
asciilifeform: saphire worx, diamond worx, si worx (and currently cheapest)
asciilifeform: mp_en_viaje: substrate gotta be a dopable insulator
asciilifeform: ( current/historical. thing'd work just as well in 1970s 4um as in today's 8nm etc )
asciilifeform: mp_en_viaje: i dun presently know of an economical non-si substrate. was thinking strictly in the bounds of current commercial processes.
asciilifeform: generally you wouldn't want 'sparse die' tho, nobody cancelled speed of light etc
asciilifeform: it aint even like you can't buy a 30cm piece of si crystal. errybody does already, they simply cut it into 1cm^2 squares. simply costs.
asciilifeform: dunno if you could use an unmodified disk writer, given as the largest practical die is still smaller than the spindle hole. but same write head defo.
asciilifeform: mp_en_viaje: y'mean the faux-asics that were relabeled xilinxen lol
asciilifeform: simplest physical realization of this, would be to position eprom cells along a spiral. then can program via ordinary uv laser in konsoomer 'dvd-r'.
asciilifeform: the config logic is ~80% of the sq.metrage, in an item like this.
asciilifeform: rather than via the usual cascaded shift registers. get 4-5x the density, 'for phree'
asciilifeform: 1 interesting, imho, variation, would be to program the config regs ~optically~, a la 'cd-r'.
asciilifeform: ( before you laff -- sovok in fact did bake fpga. i have a sample. but it was mid-80s state of art, i.e. metallization-programmed )
asciilifeform: as it is, no one (surprise!1111) bakes.
asciilifeform: i suspect if sovok had lived another 2-3 yrs, there's be ddr-baked examples of this in my parts box.
asciilifeform: theoretically, this kinda thing is chemistry-insensitive, could bake it on any process available, denser 1 will simply give you moar cells.
asciilifeform: cuz most actual circuits consist of many small islands of mechanism, connected via narrow paths
asciilifeform: mp_en_viaje: routing is the typical eater of sq.metrage in fpga
asciilifeform: they also had a variant with tree-like local structure, for same
asciilifeform: ( orig author had only 2 long aluminum lines, die-wide, for 2 phase of clock )
asciilifeform: i would've added row/column lines , to cut down propagation delay when you bake internal bus, but it's moar or less exactly The Right Thing as-is
asciilifeform: would simply need additional metal layer.
asciilifeform: can cube, no particular reason wai not. or even hypercube.
asciilifeform: it's entirely identical to what asciilifeform proposed in '15
asciilifeform: they even sold a card where you could plug in N of these, in tile pattern, and get whatever size fabric you like.
asciilifeform: d in series. ) simple enuff to simulate deterministically (and calculate propagation delays on paper..)
asciilifeform: not wholly unrelatedly, asciilifeform's semi-automated archaeology birthed a logworthy output recently. seems like in '80s there was an outfit, 'algotronix', that xilinx bought an' killed , to bury the product in patent liquishit. had entirely homogeneous fpga , made from identical ~200-transistor cells ( with simple north-south-east-west tile interconnects, and 1 flipflop inside, configged via 16bit shift register per cell, connecte
asciilifeform: huawei's item was the champ, even worked (with a little perling) to send/receive voice calls (why to do this, is separate q, but it does work)
asciilifeform: i reviewed several in the logs, in '14-'15
asciilifeform: mp_en_viaje: i have nfi what the ' ~100kb init.sh (that ~requires root~) ' horror might be, the only ones i've ever used simply present as a hayes-style modem via usb (a la FG)
asciilifeform: ( or did mp_en_viaje drag a sovok-style satellite rig with him... might explain the 200kg lol )
asciilifeform: mp_en_viaje: i confess , i assumed you were already connecting through a 'buy a local simcard' thing of 1 kind or another
asciilifeform: iirc ended with the old ban on peddling liquishit with ~0 actual ch. in it, as 'chocolate', formally overturned
asciilifeform: i dunno re mcd, but specifically recall a protracted litigation-wank re who gets to claim to sell 'chocolate' in the reich
asciilifeform: it does?! ( i thought they carefully avoid making any such concrete claim.. )
asciilifeform: mp_en_viaje: boeing claims ada in 7xx series. but i have no means to verify .
asciilifeform: mp_en_viaje: re 'avionics people' -- tried as i might, found only the hole, but not the fossil. ( ~somebody~ pressed for the lang standard to have the http://www.loper-os.org/?p=1913#selection-349.0-1150.0 knobs. but who? and where used ? i do not know to this day )
asciilifeform: afaik fr was zombie at least since de gaulle died
asciilifeform: possibly, i haven't looked inside post-obummer paris..
asciilifeform: whether happened yet or not, it dun particularly concern us imho -- any moar than mp has to think, when dining on foie gras, about rats gnawing on a goose carcass that died over a junkyard somewhere
asciilifeform pictures already the coming orgy of derps , writing 'ada' cum heapism/pointers , so to 'feel like a trader^H^H^H^H^Hboeing' etc
asciilifeform: if indeed so, i suppose it's a good job that we forked it before it got 'found'
asciilifeform: there is?! (since when?? i -- mercifully -- apparently missed)
asciilifeform: asciilifeform would find it interesting to read the 1980s ada that's running on boeing etc. , but so far never found any leaked pieces thereof. would be interesting to see if resembles e.g. ffa style.
asciilifeform: thing hid in a cave from the 'open sores movement', and so kept some semblance of sanity , but at the cost of becoming essentially 'found martian artifact' from asciilifeform-circa-2016 pov
asciilifeform: it's roughly similar to the commonlisp situation -- most of the extant coad is old/commercial/inhouse, unpublished.☟︎
asciilifeform: there aint so many names, even if you count erryone who's so much as touched the subj
asciilifeform: kazakov's thing isn't an ada tutorial, it's a (surprisingly well documented, for a heathen) lib collection
asciilifeform: he has parsers, tcptronics, various datastructures
asciilifeform: ^ looked solid on surface, but must admit that asciilifeform did not attempt to put to use
asciilifeform: this is where i confess that asciilifeform is not currently tuned in realtime to #e news, does not know what, if anyffin, the players have birthed
asciilifeform: i am unequipped to pontificate re euloratron, but as i recall the 'problem', such as there was, lives mostly in the 100MB+ of cpp legacy ???
asciilifeform: near as i can tell, these folx simply sat down and 'wrote c++ in ada', is all there was to it.☟︎
asciilifeform: 1st major piece of 'example' asciilifeform tried to eat, actually was the bignumtron ~inside gnat~ , in '16. and quickly barfed.
asciilifeform: so i had to sweat it out from first principles.
asciilifeform: 'everybody' used copious heapisms, pointerisms, 2ndarystackisms, etc. supposedly somewhere some avionics people didnt, but naturally never bothered to publish.
asciilifeform: diana_coman: so far i've found that reading heathen ada examples ~cost~ me time, rather than saved, and put into my head things that later had to laboriously pump out. and the zip fella is no exception.
asciilifeform: kudos to phf btw for the colourized display
asciilifeform: diana_coman: what made you remember the item ? ( was looking for lzwtron ? )
asciilifeform: diana_coman: i'm quite skeptical re the 'unavoidable' of the use of unboundeds and pointerisms (in re the latter, outside of unix api glue) in the general case, tho
asciilifeform: diana_coman: he's where i lifted the 'gnathtml' coad-to-www method thing. but i never had any occasion to use his zip lib in the field
asciilifeform: d00d dun seem to actually have problem self-voicing tho. ( does, sadly , have problem with concept of reading log, but perhaps curable.. )
asciilifeform: OriansJ: if you read today's log and genuinely found 0 to say, i cannot fathom what sorta 'mutually beneficial cooperation' you had in mind .
