mircea_popescu: !Qlater tell spyked any interest adding ^ functionality to spykedbot ? ☟︎

asciilifeform: in other quasi-noose, asciilifeform derived the general form of pulse equation for http://btcbase.org/log/2018-07-22#1837163 . and the antenna geometry... ☝︎

a111: Logged on 2018-07-22 17:07 asciilifeform: interestingly, both tx and rx end is considerably simpler, physically, than conventional periodic radio -- you dun need oscillators, tuners, at all. aside from pulse shaper, whole thing fits in fpga.

mod6: <+asciilifeform> BingoBoingo, mod6 : *196 == 'C' , confirmed << thanks asciilifeform!

mod6: Lords and Ladies, one rockchip has become available (ready by end of the week), who wants it! $75/mo if you sign up for a quarter, $100/mo on a month to month.

mod6: BingoBoingo asciilifeform ben_vulpes : correct me if I'm wrong, but we have a bunch of FGs available (with cables now) right?

mod6: All: 0.00104167 BTC/mo. to attach an FG to your newly rented Rockchip!

BingoBoingo: * neo-cool21 has quit (Killed (Unit193 (Spam is not permitted on freenode.)) << Oh the IRC-Cops have a filter nao?

mircea_popescu: in other sorta-lulz : ewing's sarcoma is an extrmely rare (sarcomas are in general rare in humans, but this is bone-ish origin, so even rarer) that presents in about 5 cases per million in the us, about 2 cases per million in the rest of the "industrialized world" aka pantsuitlands, and sub 1 per million in the rest of the world in general.

mircea_popescu: HOWEVER it presents in 3 cases per 20 kids in a "temporary class" in north carolina while their school underwent renovation.

mircea_popescu: all i can say is thank you hillary clinton for stopping smoking.

asciilifeform: mod6, mircea_popescu , ben_vulpes , trinque , et al, plox to update noad tables.

asciilifeform: ( asciilifeform's local isp has dynamic ip, but changes erry other year or so )

asciilifeform: pretty annoying, actually, every yr i wake up to a mess of broken ssh pipes...

asciilifeform: ( tbf, was up previously, simply returning old ip to peers )

asciilifeform: http://btcbase.org/log/2018-08-01#1838902 << was rereading this thread, and realized that sadly nodice: 16bit (late years) isa, x 8MHz gives you 16MB/sec theoretical max, which is no kind of serious scope at all ☝︎

a111: Logged on 2018-08-01 22:29 mircea_popescu: (if the putative fast oscilloscope ever got interfaced with killer micro box, it'd be through isa also, i'm sure.)

asciilifeform: if one is willing to dispense with vintage cards, and take it to the 20MHz or so (beyond which the capacitance of the contacts becomes problem) that's still not anywhere near GB/s

asciilifeform: however! this does not mean that the 'progress' idiocy where they replaced isa with a stateful monstrosity, is justified -- one could still have an isa-style bus today (i.e. directly addressable by cpu, and cards have simple 'is this for me?' logic, rather than book-length ???? )

asciilifeform: but point being, 'killer scope' won't be plugged into same bus as soundblaster16...

asciilifeform: meanwhile, in dept of 'the lady doth protest too much', http://www.contravex.com/#footnote_12_21699

asciilifeform: diana_coman, mircea_popescu : i'd still recommend adding a timeout ( and log alarm if it ever actually times out ) to the FG reader in the s.mg routine -- it isn't physically impossible for the box to die

asciilifeform: ( theoretical lifetime of FG is anywhere from 30+ yrs , until electron migration nails the eeprom in the cpld , but nobody actually knows, tho fwiw this particular chip existed since 1997 iirc and no known failures , so lives at least this long )

asciilifeform: the added bonus would be that if run on a misconfigured system, it will do something moar informative than simply hang.

asciilifeform: meanwhile, in resurrected vintage lulz : linus agreed ( https://archive.is/aFETR ) to merge the http://btcbase.org/log/2018-04-12#1796987 shitshow into kernel . ☝︎

a111: Logged on 2018-04-12 15:22 asciilifeform: zx2c4: author of 'wireguard' ?

mircea_popescu: asciilifeform was it capped at 8mz ?!

mircea_popescu: note, i said agpx!

asciilifeform: mircea_popescu: wasn't capped, originally was 1:1 with cpu clock, then starting with 386 or so started being divide-by-4

mircea_popescu: i kinda missed that memo.

asciilifeform: and lol agp ( interesting q, did anybody ever make something other than a vga card for it ? or for that matter, a mb with >1 hole )

mircea_popescu: why lol ?

mircea_popescu: afaik it even comes double-stacked on some boards, and is UTTERLY capable of gb/sa

mircea_popescu: afaik also isa-on-steroids, but i've never looked THAT closely

asciilifeform: lived for quite short time ( asciilifeform has all sorts of vintage gear but 0 boxen with agp remaining )

mircea_popescu: sure as fuck it isn't the level of mess of usb.

mircea_popescu: i have some.

asciilifeform: mircea_popescu: it was moar interesting than this, was a ~port~ rather than bus, dedicated thing

mircea_popescu: right.

mircea_popescu: most of the vidcards are like are agp

mircea_popescu: not fucking extinct at all!

asciilifeform: well extinct in the dec alpha sense. ( 0 made since, idk, '07 ? )

mircea_popescu: i wouldn't even bet on that.

asciilifeform: mircea_popescu: what's your most recent mb with said hole ?

mircea_popescu: but i do have 2-hole board right here, and the vga card to go with it.

mircea_popescu: hmmm.... lessee

asciilifeform: all i've left re agp, is the bound paper standard (yes..) . and it indeed permitted 2 holes ! but i've not ever encountered a mb that had the 2nd one populated

asciilifeform: ( my one gripe re agp, and i suspect the reason why nobody afaik made e.g. disk controller for it , is that it had asymmetric bw -- substantially faster output than input ; thing was specifically sharpened for vga )

mircea_popescu: jesus this will take some degriming.

mircea_popescu: asciilifeform afaik it's just pci tweaked.

asciilifeform: mircea_popescu: loox like last agp item ever mass marketed was radeon 4670 ( itself a rarity ), circa '08

mircea_popescu: asciilifeform item is asrock, 939dual. here's a shot : https://i.testfreaks.com/images/products/340x170/247/asrock-939dual-sata2.888823.jpg

mircea_popescu: (not mine)

mircea_popescu: can't really tell when it was discontinued, or if. vendor actually still carries it : https://www.asrock.com/mb/ULi/939Dual-SATA2/index.asp

asciilifeform: mircea_popescu: i see 2 diff slots in there ( not counting pci )

mircea_popescu: right

asciilifeform: what's the middle slot ? ( it isn't pin-compat with the yellow agp )

mircea_popescu: of course from looking at their actual specs, they list "- 1 x AGP8X/4X slot, 1.5V only - PCI Express x16 slot" rather than dual agp per se.

mircea_popescu: afaik agp ~= pci-e, but i suppose technically i might've actually misunderstood what's going on in my mobo ?!

mircea_popescu: tbh i've not even thought about any of this in decade+.

asciilifeform: pcie is the current pci ( as seen in e.g. the pizarro boxen )

asciilifeform: agp was 1999-2008, roughly item, double-stacked pins, afaik only vga cards made for it.

asciilifeform: http://www.asrock.com/mb/ULi/939Dual-SATA2 << your vintage mb . 1 agp slot, 3 trad pci, 2 pcie , and... 1 oddball 'future cpu slot', nfi if anything ever sold for it

asciilifeform: ( this was a kind of pestilence in early 2000s, there were 5-6 types of vendor-proprietary wtf-slots, afaik ~0 products sold for'em )

mircea_popescu: no that's amd's mid 2010s chips

mircea_popescu: well, maybe early.

mircea_popescu: asciilifeform you know the vidcard actually has two feet, in both mid slots.

mircea_popescu: so the idea is, 2nd was only used for power or what am i missing ?

asciilifeform: and iirc was also attempt to cure the plague of massively-heatsinked gpu monster popping out of the slot during transport

mircea_popescu: who the hell doesn't take it out ? can actually break the connector pcb part.

mircea_popescu: aaanyway. so it turns out "2 slot" is really 2010s era fakery, not really used as such. and i fell for it!

mircea_popescu gotta remember he's well advised to not put his 20yo self unfiltered in the chan, lol.

asciilifeform now has the notion that he has a board exactly like mircea_popescu's at the bottom of some ancient crate...

mircea_popescu: kinda what threw me, "wtf are you talking rare, these were so pestilentially common for a summer or two even i ended up with some".

mircea_popescu: but at least we figured out "vidcards i like" has~nothing to do with "dual slut", everything to do with ~how agp8x even is~.

mircea_popescu: uhm, i mean slot. slot. srsly now. not freudian at all.

asciilifeform: from asciilifeform's pov, 2007-9 was 'peak mobo'. e.g. the http://www.loper-os.org/?p=1871 opteron, still in service, is circa '07 with '09 cpus

a111: Logged on 2014-06-20 19:17 asciilifeform even now running amd hardware ('tyan' circa 2007) largely because amd mobos with ecc support and multiple pcie-16 slots have vanished into some mysterious black hole.

mircea_popescu: just about.

diana_coman: BingoBoingo, please plug back in the 2nd FG on smg test server; anytime in the next 10 hours is fine, I'll shutdown the machine now
