feedbot: << Bimbo.Club -- TMSR Log Summary - 11/22/2018 [00:31]
asciilifeform: << on 2nd thought, 'no reported breaches' could mean 1 of 2 things ! [13:23]
a111: Logged on 2018-12-14 01:57 mircea_popescu: tbh, a recuperative scholarly series on sns would be most apt use of scholar's time. [13:23]
asciilifeform: ( and not necessarily the 1 implied by commenter.. ) [13:24]
asciilifeform: in exactly same way that 'no reported thefts of gold from ft.knox' can mean 1 of 2 things. [13:25]
asciilifeform: ( see also e.g. ) [13:26]
a111: Logged on 2017-05-23 02:41 asciilifeform: per dijkstra's 'testing can demonstrate the presence of bugs, but never their absence' [13:26]
feedbot: << Qntra -- Germany Changes Sex Entries In Birth Registry To Add Third "Diverse" Option [13:43]
mircea_popescu: hey, wasn't proclaimed the golden veal. merely worth documenting. [14:24]
mircea_popescu: since we're apparently all into bolixology or w/e you'd call it. [14:24]
asciilifeform: mircea_popescu: believe or not, bolix aint even the least-gettable old/interesting comp [14:27]
asciilifeform: e.g. xerox lispm is rarer still ( and had own merits, which i pieced together 100% from docs and surviving photos and won't even go into in depth because approx as questionable as archaeology of merv... ) [14:28]
asciilifeform: lotsa ancient artifacts are imho worth documenting. tricky bit is getting at the surviving crumbs. [14:29]
mircea_popescu: sure. [14:29]
asciilifeform: specifically in re 'iron built for reliability', 'tandem' was interesting. i dun expect to ever lay hands on 1 , tho [14:30]
asciilifeform: even the old ibm irons have a few things to teach pc re redundant/votingcircuit scheme. [14:31]
asciilifeform: ( i.e. box had multiple cpu that had to majority-agree re outcome of a cycle ) [14:32]
asciilifeform: reportedly items like this are being orbited , as cost-saving measure in place of ye olde saphire semiconductors. but there's ~nuffin publicly written re just how built. [14:33]
asciilifeform: afaik all such schemes still suffer at least 1 'jesus bolt'. [14:34]
asciilifeform: the win, when there is a win, is that you can make the jesusbolt 'stateless', i.e. if particle whacks it, it resets and retries the last cycle rather than going into metastable strange [14:36]
* asciilifeform distant from subj, cannot comment in detail re how well worx [14:36]
phf: asciilifeform: i worked on tandem for a bit (known by then as HP NonStop), i appreciated the architecture, but entire software stack was cobol [17:46]
phf: well, i appreciated it in theory, didn't have enough active drive to grok it, nor the necessary background [17:47]
asciilifeform: oh hey interesting phf [17:47]
phf: i still remember one of the cobol guys pulling out random bits from it on day one and going "i can just pull a bunch of things and it keeps working" [17:48]
asciilifeform: btw phf i hate to repeat meself but am i ever gonna see that bolixgem you dug up, or will i have to get whole thing from xray [17:48]
asciilifeform: ( the crate is slated to arrive tomorrow morning... ) [17:48]
phf: well, you'll still have to xray some, because i barely have anything on macivory, but i'll go over the scans this weekend. i actually have (miracle of miracles) free weekend coming up [17:49]
asciilifeform: mircea_popescu: i'ma prolly end up xraying with own hands, i dun trust heathen derps with the jools [17:49]
asciilifeform: phf: defo will have to xray, but thought 'oh hey possibly phf's material will give sumthing to correct against' [17:50]
asciilifeform: what i could really use is some PAL/GAL src. if ever turns up. will make the affair go 9000x quicker. [17:50]
asciilifeform: ( fwiw i still dunno if the bolix people set the lock bit in those things or not possibly they didn't even ) [17:51]
asciilifeform: phf: my current plan for that box is , roughly, [17:52]
a111: Logged on 2018-12-13 18:53 asciilifeform: 1st logical step , on the magic day when asciilifeform has both pcb layout and GAL contents nailed down, will prolly be to make an exact physical copy of the board. [17:52]
asciilifeform: ( i aint gonna stick to the period srams/drams, cuz that'd be simply dumb , each really belongs as 1 chip ) [17:53]
asciilifeform: ( and really dun need dram at all, the drams on the daughterboard are all connected through period auto-refresher ic that presents as a sram ) [17:53]
phf: so you want to make a replica that plugs into same hardware? i thought you'd want to do a fake mac harnes first? [17:54]
phf: i.e. get macivory working outside of macintosh context [17:54]
asciilifeform: phf: when thought about it, realized it was mistake : gotta find what the external-to-cpu logic on that thing actually does [17:54]
asciilifeform: plus i'ma need ivorytron with direct probes on the cpu lines, and there aint any room for such a thing in the orig [17:55]
phf: fair [17:55]
phf: you know if ivory on macivory actually replaceable, the way it is on xl? [17:55]
asciilifeform: ( actually 1st item will actually be to ditch the ancient scsi hdd and replace with solidstate. i'd hate to lose the box to platter rot ) [17:56]
asciilifeform: phf: socketed [17:56]
asciilifeform: in fact damn near errything but the filter caps is socketed. [17:56]
phf: yeah, the scsi/solidstate adapter exists, is actively used for "retro hardware" [17:56]
asciilifeform: aha [17:57]
asciilifeform: fortunately was quite gettable [17:58]
asciilifeform: ( didn't exist ~5y ago when i last contemplated doing all of this ) [17:58]
feedbot: << Daniel P. Barron -- This goes against all human rationality. [19:29]
asciilifeform: phf: i am thinking, instead of burning time on emulating 'nubus' and ancient crapple, when working (from mac-side pov) clone exists i'ma drive it directly via onboard ft2232hl or similar ( the mac-side src , i've had for yrs, and it's quite straightforward re what is done to the card once i know what specifically happens on the card when nubus regs are written, may as well do it from pc directly to/from the ivory cpu via usb-to-5v-f [19:30]
asciilifeform: ifo ) [19:30]
asciilifeform: a sort of anal feeding, if you will. [19:31]
asciilifeform: the item can then be used as fairly compact instrument to probe behaviour of the chip vs. the old emulators. [19:32]
asciilifeform: incidentally, i had potentially interesting notion: a modern-day digicam ccd, of e.g. 25 'megapixel', is just about dense enuff that one could take a meaningful xray of the ivory die, if one could be found that responds to xray.. [19:35]
asciilifeform: very much an open q tho. [19:36]
asciilifeform: danielpbarron: full bore calvin, eh [19:37]
danielpbarron: me? no, calvinism leads to hell [19:38]
asciilifeform: danielpbarron: plox to expand then, what do we get when we xor danielpbarron's no-free-wills with calvin [19:38]
danielpbarron: the best explaination is linked in that article, [19:39]
danielpbarron: but calvinism promotes the false doctrine of limited attonement [19:39]
danielpbarron: the idea that Christ died only for the elect, rather than for the entire world [19:39]
asciilifeform: also possibly i missed sumthing, but didn't danielpbarron schism from 'truechurch' ? [19:40]
asciilifeform: ( or was it over some other doctrine ) [19:40]
danielpbarron: huh? i am part of "a true church" -- idk where you got the idea i left [19:41]
asciilifeform: hm [19:41]
asciilifeform: !#s darwinfish [19:41]
a111: 1 result for "darwinfish", [19:41]
asciilifeform: hrm [19:41]
danielpbarron: maybe you are looking for this [19:42]
asciilifeform: could've sworn there was sumthing re a schism [19:43]
danielpbarron: yeah, darwin split from grace comminity baptist, and al soto split from darwin's thing [19:43]
asciilifeform: a [19:44]
* asciilifeform bbl : off to maffs room for ~3rd~ rewrite of ch14... [19:47]
asciilifeform: meanwhile, in phuctor q&a, [22:27]
asciilifeform: ( ben_vulpes : can haz logging back in #a plz ? ) [22:27]
asciilifeform: do i have to write own log bot nao on top of errything else ? [22:27]
