asciilifeform: though to some extent space locality is also built into drams as we know them

asciilifeform: and is only really meaningful for a general-purpose cpu, the concept is not even defined re something like a miner

asciilifeform: incidentally, the 'branch is wasteful' thing taught in school has to do entirely with caches, and ergo is not relevant in a flat memory (e.g., the inside of a miner)

asciilifeform: whereas in mathematical fact, it is.

asciilifeform: there is some confusion in the literature because certain sly operators would have you believe that - e.g., a conditional MOV - is not a branch.

asciilifeform: was in re mod6's dream machine

asciilifeform: what i was talking about is that branching is why you can't sign program state, because of combinatorial explosion.

asciilifeform: no

asciilifeform: l0l

asciilifeform: hey it makes more sense than my dream ! (see log)

asciilifeform: otherwise the scheme devolves into tivo.

asciilifeform: but in all cases, you want to sign things that are at least in principle human-readable

asciilifeform: in that case one signs an input.

asciilifeform: i dun get it

asciilifeform: what'd be the point of signing program states ?

asciilifeform: mod6: if you already know the output, sign ~that~

asciilifeform: mod6: branches

asciilifeform: BingoBoingo: documented gpu.

asciilifeform: for all i know they are already shipping evil chip.

asciilifeform: but ~this won't last long~

asciilifeform: BingoBoingo: 'pcengines' sells g-series (well-documented, blobless 'coreboot', etc.) chipset boards, see old logz

asciilifeform: whole shebang is weak.

asciilifeform: nor will ddr2 dram remain available for long, i suspect

asciilifeform: (not only socket, but northbridge, differs)

asciilifeform: socket was changed, they cannot be used with recent boards

asciilifeform: briefly returning to the opterons, unfortunately they are quite useless alone, they must be stockpiled with ~period mb~

asciilifeform: l0l!!

asciilifeform: all you gotta do is not branch!1111

asciilifeform: l0l

asciilifeform: patents in modern world are 100% scamola.

asciilifeform: (this does not include cost of litigating, either.)

asciilifeform: mircea_popescu: what sort of tard does one need to be to blow 50kus on patent ?

asciilifeform: (but omfg!111 how can we produce clockless chip!111 synopsys corp dun sell a cad for it!11)

asciilifeform: even though it would be up to 100x boost per-watt

asciilifeform: notice, nobody has produced CLOCKLESS miner

asciilifeform: who recalls the discussion of muller gate ?

asciilifeform: the tardz.

asciilifeform: omfgh

asciilifeform: the kind of thing i assumed the existing producers HAD IN 2012

asciilifeform: this is pretty minor.

asciilifeform: ^ de-pdfized

asciilifeform: http://dpaste.com/3RYGC5Y

asciilifeform: ben_vulpes: i'ma guess it was some variant of satcoin

asciilifeform: ah, then it!

asciilifeform: mr mold's scientocracy ?

asciilifeform: what 'science'. 'here's a copy of xp from bazar'

asciilifeform: (nearly UNIVERSAL in orc world)

asciilifeform: same reason the idiots run winblowz

asciilifeform: because 'cheap'

asciilifeform: as does ru

asciilifeform: mircea_popescu: the reason i said 'not only intellectual property' is that cn is happy to piss on american patents but STILL continues to churn out straight knockoffs of usg crud

asciilifeform: if it were only that!

asciilifeform: all but 1 - asia

asciilifeform: 5+ firms.

asciilifeform: ram is commoditized.

asciilifeform: but it would be mega-improvement if folks outside the большая зона were buyin'.

asciilifeform buying

asciilifeform: who wants - can find.

asciilifeform: btw i found that old opteron is being sold surplus by the tonne

asciilifeform: aha.

asciilifeform: i just installed spiffy upgrade in january, from circa-'06 to '08 opteronz!

asciilifeform: hey they're still usable!111 just dun buy post-'13 chip.

asciilifeform: ftr cardano cpu is a mips knockoff.

asciilifeform: but let's not conflate the two

asciilifeform: mips ~company~ is a parasite, just like arm co.

asciilifeform: mips is ~100 lines of verilog, if i had to pick an arch we could potentially bake one day, i'd pick that.

asciilifeform: as in, kernel does not boot unless microshit permits it.

asciilifeform: in particular, tivoization means that ~your pc is a nintendo~ with microshit - holding the signing key.

asciilifeform: the linked essay speaks for itself, described - for n00bz - precisely why merely cutting off the net pipe does not sanitize a box.

asciilifeform: nor against tendrils that seek out and 'specifically diddle', e.g, gmp mult.

asciilifeform: mircea_popescu: airgap will not help against tivoization.

asciilifeform: i looked far and wide, even turned up, e.g., that renesas still manufactures the super-H (sega!)

asciilifeform: the cpu situation is dire, far more so than anyone here realizes afaik.

asciilifeform: BingoBoingo: l0l saint

asciilifeform: the result - VERY discouraging.

asciilifeform: back to thread, briefly, i regularly survey the market for cpu-that-could-bitcoinate

asciilifeform: just as a broken-down toyota in a tow yard is more of 'car' than a rusty ww2 tank sans engine.

asciilifeform: mircea_popescu: ah in that sense yes. but it is STILL an intermediate product, far closer to actual src than binarysoup.

asciilifeform: mircea_popescu: rotor takes you from bare metal (currently x86 and arm but potentially vax or whatever) to bitcoin.

asciilifeform: mircea_popescu: trb's www

asciilifeform: briefly back to thread, every other month or so i do an exhaustive survey of commercially-available cpu

asciilifeform: no, where do i get 'full source for x86'

asciilifeform: mircea_popescu: where ?

asciilifeform: it is available NOWHERE

asciilifeform: none!

asciilifeform: at least one can get src for bitcoin.

asciilifeform: and not fully reversed.

asciilifeform: afaik every single on without exception includes 'licensed' crapolade that is documented nowhere

asciilifeform: arm would be usable if there were EVEN ONE documented arm chip available.

asciilifeform: in agonizing detail.

asciilifeform: but ftr i discussed the intel and amd 'palladium' engines in detail in the old logz.

asciilifeform: otherwise works about as well as the winblowz defense.

asciilifeform: mircea_popescu: if 'rule of law' were an actual thing, aha

asciilifeform: i have this machine, sweated over it for ages, no useful result.

asciilifeform: it contains evil gpu without which it is unusable, and there is NO known doc for it

asciilifeform: one nitpick: the c201 chromebook he recommends as a potential arm box is a TURD

asciilifeform: heh

asciilifeform: not actually news, note, to veterans of tmsr

asciilifeform: ^ 'palladium' won.
