SeanRiddle: When I starting posting pics I was hosting my domain at home and the big pics would kill my access. blogspot limits the max size, so I uploaded to wikimedia. Now I'm using a real web host, so I guess I could put everything there.
a111: Logged on 2018-11-30 19:52 SeanRiddle: That's the lo-res pic. Wikimedia sometimes chokes on my big pics, and I have to upload smaller ones. Go down to the File History and there's a link to a 43Kx45K pixel pic.
SeanRiddle: I haven't. Fiji can do focus stacking, but I haven't tried that yet. I've got an XY table and I rigged a stepper to the focus knob, so I could take n pics at different focus for each tile.
a111: Logged on 2018-11-28 19:28 mircea_popescu: you put in a violet source, take a pic. next you put in a green source, take a pic. next, yellow and red.
mircea_popescu: we defo need a tree massager. this problem will reccur.
mircea_popescu: a horse that goes 90% of the way to paris still can't make any part of stagecoach to paris.
asciilifeform: and ~then~ ( and this is what we have, but su reversers did not ) you load the thing into a (fairly inexpensive) fpga and try functional tests.
mircea_popescu: if you were to attempt to do ~more~ machined reversing than merely "build me netlist", wouldn't the correct approach be to a) build binary tree of transistors and b) sick tree massager on it ?
mircea_popescu: asciilifeform is there any difference between the netlist and a binary tree of transistors ?
mircea_popescu: the more we tal;k about this, the more it's evident what's lacking isn't MERELY x or y. we're lacking a buncha pieces here.
mircea_popescu: you know, if we had working svg thius would be such an eminent application for a svg scroll-through-er.
a111: Logged on 2018-11-29 19:24 asciilifeform: on other front, phf : on occasion of the most recent bolix thread , i went and looked again at the http://btcbase.org/log/2018-01-17#1771955 artifact ; it is interesting that they provided 128 iron types, incl. bignum, but not a 'bignum of fixed N words'. i guess in '80s ~nobody was thinking of crypto at all. ( and i was prolly unduly pessimistic to the orig finder of $item, it is prolly 95% of what's needed for cycle-accurate clone.
asciilifeform: my 'cyrix' worked a+++.
asciilifeform: e.g. 'hey why is power connected to ground, must be a speck of skin in pic'
asciilifeform: mircea_popescu: nope, gotta preprocess the thing to get a draft netlist (i.e. what's connected to what) and only then can walk the photos to search for barfolade
asciilifeform: ( i.e. you don't, not till you actually bake a working and satisfying cloned circuit )
mircea_popescu: in my mind people just sat with a patient needle and marked down 300k locations.
asciilifeform: a kind of specialized ocr.
mircea_popescu: people only look in one spot at a time anyway
mircea_popescu: i dunno, maybe i'm just not grasping something fundamental. but it seems to me that for reversing work, 2400 pics with margins beats a 600mb monstrosity.
mircea_popescu: you know, i think he actually has a point ?
asciilifeform: ( it aint even matter of cost; simply we're dealing with an almost-extinct animal. there's maybe a few dozen of these left in the wild, optimistically )
SeanRiddle: Heh - I was not told the value! Why not use a pro decapper? But you wouldn't torch that package.
asciilifeform: SeanRiddle: just so you're aware of the orig subj -- the ic we were looking to see decapped is worth mebbe 10,000 $ ea. ( and at that, i have 0 guarantee of being able to find more . ever. ) i have a grand total of 2.
asciilifeform: or hm, this one's about a 'Amstrad 40010'
SeanRiddle: That one was a blowtorch decap, so some of the dirt is residue from the plastic encapsulation. I can clean that with HN03.
asciilifeform: ever succeeded with a 1um ?
asciilifeform: ( and there are at least a dozen micrographs available )
asciilifeform: that 6502, is a 8 micron ic, almost half century old nao
asciilifeform: SeanRiddle: were you ever able to actually re a circuit from your photos ?
asciilifeform: it is my understanding that any dust at all is a problem for this job
SeanRiddle: I'm taking jpgs with the camera and then stitching those with fiji. It looks as good to me as using RAW, but a lot easier.
asciilifeform: why's it a jpg anyway, wouldn't this introduce artifacts ?
SeanRiddle: It's a Canon EOS 5D ☟︎
SeanRiddle: That's the lo-res pic. Wikimedia sometimes chokes on my big pics, and I have to upload smaller ones. Go down to the File History and there's a link to a 43Kx45K pixel pic. ☟︎
asciilifeform: it's a good try, but i dunno that this is usable for re.
a111: Logged on 2018-11-30 19:14 Mocky: http://btcbase.org/log/2018-11-30#1876406 I won't get a chance to look at this until signed up with new daily bread overlord
asciilifeform: costs whatever the miner fee is, plus epsilon for payload ( most of the current chinese won't mine a 0-summing tx iirc )
asciilifeform: but sure can stuff in whatever bytes, iirc addr decoder barfing dun invalidate a tx , classically
mircea_popescu: your own "blockchain telegraphy" and a buncha "child porn in blockchain" antiqua are there
mircea_popescu: asciilifeform there's a small space in a tx to add some text.
a111: Logged on 2013-12-01 15:21 ozbot: MIT graduates cannot power a light bulb with a battery. - YouTube
asciilifeform: current mit is a kind of nursing home, as i gather
asciilifeform: ( somewhere on my hdd, there's a photo of shrobe walking across a stage holding up a 3620 , the kind in http://www.loper-os.org/?p=51 , in his hands, 'looksy, first 'portable' bolix' )
asciilifeform: always worth a shot
a111: Logged on 2018-11-30 17:27 mircea_popescu: btw Mocky -- teh bot dies through the following : often it makes so much stuff in one click it overwhelms its weight carrying capacity. any chance you can implement a fragmenter-if-overweight ? it's often enough to be a pain in the ass by now.
Mocky: http://btcbase.org/log/2018-11-30#1876406 I won't get a chance to look at this until signed up with new daily bread overlord ☝︎☟︎
Mocky: "The other address has one notable transaction which is sent from 1JEWSxAgGhSFuNPHUAr13zftNLjYt5wZaS and 1MoSSaDDSStrRo53YjPaGcXiABAXfYuvEL. A dust transaction, it was confirmed in block 551895."
Mocky: "Still, a total of 6-7 transactions had been sent to the addresses by time of writing, some with intriguing transaction details. For instance, this transaction has an embedded message:
asciilifeform: mircea_popescu: house, was fulla iron, old moldy cards, hdds, consoles. dks was/is a repairman, afaik mechanical engineer orig by trade .
mircea_popescu: eh, the red stapler guy, shit's always at his house. periodically they find a "traitor" fo this kind, had 9000 "secret" hard drives in basement.
asciilifeform: ( he condescended to give asciilifeform a keyboard pinout, and had to 'go to warehouse' to get )
mircea_popescu: wasn't there also a shared setup ?
asciilifeform: diana_coman presently uses, and BingoBoingo , and a few other folx, worx great
a111: Logged on 2018-01-17 20:47 asciilifeform: to be fair the company was not really a honest commercial co, moar like one of those unofficial usg research institutes, they proliferated under reagan and died with him
asciilifeform: mircea_popescu: indeed, tho quite ironically bolix itself was quite analogous to a su research town
mircea_popescu: remember back when they had folks who went to school ? "elite" husband-and-wife team could bake a great z80 game over a summer, and so on.
asciilifeform: However, the common way of measuring chip complexity is to count the number of transistor sites; this measures the size of the internal ROMs better. Using that count, this is one of the largest chip ever done, containing nearly 400,000 transistor sites. The chip was designed very quickly (it took about 9 months from the freezing of the architecture to the first prototype chip, using a team of only 4 designers).'
asciilifeform: 'Figure 24 show some statistics about Ivory. The size of the chip was about a centimeter-and-a-half on a side in the earliest version which was done using 2-micron CMOS technology. The first commercial version will be done in a 1.6 micron process and will be about a centimeter on a side, as is the TI chip. This makes it a very large, (but not impossibly large), chip to fabricate. There are about 255,000 actual transistors on the die.
asciilifeform: ble to what you'd see in a 80386 or a 68020 class machine.'
asciilifeform: 'It is of tiie same complexity as an Intel 80386 or a Motorola 68030. Figure 21 is a photomicrograph of the chip (chip people always seem to need to show their chip pictures). The Ivory chip is more or less divided into three horizontal slices; the top is the datapath and stack cache, the middle is the control system, and the bottom is the memory interface. In the middle of the control system is a very large microstore, again compara
mircea_popescu: 2 level metal is trade name, a sort of metalization process
asciilifeform: iirc phf ( and apparently nobody else ) has the actual pinout, but iirc it is on a tape or the like and he hasn't posted yet
mircea_popescu: SeanRiddle you say !!up to deedbot in a pm.
amberglint: I found a couple more bits about the Ivory https://i.imgur.com/m5HvPHA.png https://i.imgur.com/QEzR2po.png ☟︎
SeanRiddle: Just a programmer - no comic stuff. Decapping is just a weekend hobby.
mircea_popescu: SeanRiddle what's your medium planning look like ? you wanna do more comicwork ? you wanna expand on your decapping ? what do you do for a living anyway ?
SeanRiddle: A lot of the pics on wikimedia are 40Kx40K pixels
mircea_popescu: SeanRiddle is it a case you have high resolution photos and lack hosting for them ?
a111: Logged on 2018-11-28 15:50 asciilifeform: http://www.seanriddle.com/sc1die.html << suggests that this is the case, the link to 'Here's a 17436x15128 pixel version (HD View on another server)' goes to some microshit site that doesn't actually load for me
trinque: deedbot's based upon that, usually reconnects, but it is looking like there's a case where it does not.
mircea_popescu: i kept trying to get a comic going, oglaf chick wouldn't do it, that midnight_on_mars dood with the http://pictures.hentai-foundry.com/m/MidnightonMars/435591/MidnightonMars-435591-Secret_Obsession_-_Overwatch.jpg too fucktarded to communicate... ☟︎
trinque: asciilifeform: didn't you say you had spotted a bug?
mircea_popescu: asciilifeform that's such a fucking perfect illustration.
mircea_popescu: anyway, it's a pity san fernando valley was all morons in the 90s. could have bought disney, turn it into slut educational tool.
mircea_popescu: but yes, alladin carries a pretty fucking strong scent of "oh, hi, we're ohioan squarejaws wearing bedsheets. totally legit rome sir. rome, ohio." ☟︎☟︎
asciilifeform: hey i even managed to see disneys. a coupla, with the trad ru dubbing translator with clothspin on his nose going mmmm
mircea_popescu: i suppose we're a priviledged set, had derive on ye olde 386, instead of "had stupid family, watched disney" or w/e.
asciilifeform: the notion that sumbody might turn away from 'modernity' consciously, rather than because alzheimer patient, apparently is a bridge too far for some folx ☟︎
mircea_popescu: there's a certain level of permissible idiocy in the youth. they come out of eggs.
asciilifeform: it was quite similar, imho, to the gabriel laddel fella. clearly there was 'somebody home' in the crankcase, but under a thick haze of substances and detritus from indiscriminate suction of ??? from heathendom. 'salvation of the drowning is work for the selfsame drowning', what can i say.
mircea_popescu: just like all bois could in fact be reproduced, if there were somewhere a girl with sufficient patience. there isn't.
mircea_popescu: in fact, pretty much every single pantsuit mental cockroach can be deduced from a+b above, ~including~ the strictly contradictory bits, and also including the psychotic nonsednse that allows them to maintain contradictory beliefs.
mircea_popescu: usual set of a) "you're special" cuntlet nonsense and b) "if its hard it means you don't have to do it" ustardation. they interplay the same way everywhere, it's a coherently broken philosophical system
mircea_popescu: there's not this miracle in nature, "i know he doesn't wash, but he's a great guy!"
mircea_popescu: dude's mental processes are of a certain ilk, whadda ya want.
mircea_popescu: btw Mocky -- teh bot dies through the following : often it makes so much stuff in one click it overwhelms its weight carrying capacity. any chance you can implement a fragmenter-if-overweight ? it's often enough to be a pain in the ass by now. ☟︎
a111: Logged on 2018-11-28 22:47 trinque: mircea_popescu: lulzy, but my coffers aren't stocked up for a supreme court fight just yet
asciilifeform: ( in ru variant, moar laborious cuz their setup tends to look moar like https://www.tyurem.net/album/images/narva_55_jpg.jpg -- iron grate sorta like on modern 'central ac' duct, gotta be pried apart a little with sumthing )
asciilifeform: the procedure for making the 'road' go is quite elaborate and much dwelled on in ru prison lit. ( gotta pull apart a sock, weave rope, make 'fishing rod' out of paper + bread glue etc , then run the 'horse' )
BingoBoingo: Anyways, Libertad is about a third of the way from Montevideo to Colonia
asciilifeform: http://btcbase.org/log/2018-11-30#1876362 << i'll admit, i kept half-expecting him to actually read a ch of ffa and go 'hmm... maybe i should throw out my c hairball and mecha-proofisms' but of course no dice. ☝︎
zx2c4: On my phone right now, woke up from a dream to see this, not sure if im still dreaming. Care to explain what's provoked your ire?
asciilifeform: btw , q for ffa readership, can anybody think of a way to make the digit slider routine non8bitbyte-clean ? ( beyond having ffa eat its pistol on boot if it finds itself on such machine, lol )
a111: Logged on 2018-11-30 03:22 asciilifeform: ... or that the #define ULT(a, b) ((a ^ ((a ^ b) | ((a - b) ^ b))) >> (sizeof(a) * 8 - 1)) macro dun turn to barf in the preprocessor on acct of some esoteric beard shaving from dennis richie ?
asciilifeform: ( it's a not-terrible numerics schoolb00k , ftr )
asciilifeform: http://btcbase.org/log/2018-11-30#1876333 << dun seem to be in the logs, possibly was in a private letter from sumbody.. ☝︎
asciilifeform: it's sitting in a 3ring here in my tortureroom for whatever reason.
zx2c4: Shift_Right((A and B) or ((A or B) and (not S)),
asciilifeform: consider, zx2c4 , i can show that nuffin in my arithm routines can overflow a buffer. even if you were to turn ada's overflow checks off. without any complicated tooling.
