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: 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: aaanyway. so it turns out "2 slot" is really 2010s era fakery, not really used as such. and i fell for it!
mircea_popescu: so the idea is, 2nd was only used for power or what am i missing ?
asciilifeform: for all i know, still going, somewhere.
mircea_popescu: tbh i've not even thought about any of this in decade+.
mircea_popescu: afaik agp ~= pci-e, but i suppose technically i might've actually misunderstood what's going on in my mobo ?!
asciilifeform: mircea_popescu: i see 2 diff slots in there ( not counting pci )
mircea_popescu: asciilifeform item is asrock, 939dual. here's a shot : https://i.testfreaks.com/images/products/340x170/247/asrock-939dual-sata2.888823.jpg
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 )
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
mircea_popescu: but i do have 2-hole board right here, and the vga card to go with it.
mircea_popescu: i wouldn't even bet on that.
mircea_popescu: i have some.
mircea_popescu: afaik also isa-on-steroids, but i've never looked THAT closely
mircea_popescu: i kinda missed that memo.
mircea_popescu: note, i said agpx!
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: 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 ???? )
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: pretty annoying, actually, every yr i wake up to a mess of broken ssh pipes...
mircea_popescu: all i can say is thank you hillary clinton for stopping smoking.
mod6: BingoBoingo asciilifeform ben_vulpes : correct me if I'm wrong, but we have a bunch of FGs available (with cables now) right?
asciilifeform: ( i.e. pre-existing lusers, rather than sybils baked for the occasion )
BingoBoingo: Aite, I'll walk over and stretch the legs now.
mod6: cool. the '196' number is what I received from ben in that latest document that I marked up.
mod6: All I know is that mats has number '196'.
mod6: I don't have information on which letter assignment is which.
mircea_popescu: (if the putative fast oscilloscope ever got interfaced with killer micro box, it'd be through isa also, i'm sure.) ☟︎
mircea_popescu: surprised, i am not.
asciilifeform: mircea_popescu: so happens i have a seekrit draft of ice40+isa toy
mircea_popescu: you know, i'm tempted to put "must have 4x isa" on the reqs list for tmsr mobo ANYWAY.
mircea_popescu: asciilifeform no, i know.
mircea_popescu: ftr, i still have boards running my amds with proper isa cards...
mircea_popescu: i can see it.
asciilifeform: ( bad enuff that i only even have usb2, not 3, on dulap, and it takes 3hrs )
asciilifeform: i ain't waiting 3 wks to reimage a motherfuckign 64GB stick.
a111: Logged on 2018-08-01 21:36 asciilifeform: ( i can't afford it on dulap, because it also doubles as reimaging station for rockchippen , but s.mg prolly can safely say goodbye to usb3 )
mircea_popescu: http://btcbase.org/log/2018-08-01#1838832 << i'll bet you you'll very much want to, and soon enough. ☝︎
asciilifeform: there's likewise a reason i did not publish a 'demon' to go with FG. ideally random bitz oughta live the shortest possible life, and walk shortest possible path from point of birth to use.
asciilifeform: ( erry heathen rng i know of , includes... )
mircea_popescu: right. and i didn't say anything about this then, either. also not :)
asciilifeform: mircea_popescu: observe that i did not put a ram buffer in FG (aside from the 16bit debias/accumulator ) , it was not happenstance.
mircea_popescu: 1-3 is exactly http://btcbase.org/log/2018-08-01#1838591 ; 1-2 is FG ; 2-3 is science, as in http://trilema.com/2017/is-it-still-rape-if-i-write-science-on-my-penis-first/ item. ☝︎
asciilifeform: ( i won't dignify 'esata' with a mention, it is flaky in asciilifeform's experience, and not really usable on racked boxen )
diana_coman: but now I admit I got angry with ehci after all of today's barfing on the topic
diana_coman: and yes, otherwise I was thinking that a script can't be all that difficult to write for it too
diana_coman: ah, built-in ttl serialports sounds good, yes; re problem dun seem to exist, mhm, I'd rather expect it would pop up sooner or later if used intensively in this little&frequent style
asciilifeform: diana_coman: re usb1 forcing, i was thinking the proper pill might be to write a shell thing that parses output of lsusb -t and does the correct magics ; rather than modded kernel
asciilifeform: ( i can't afford it on dulap, because it also doubles as reimaging station for rockchippen , but s.mg prolly can safely say goodbye to usb3 ) ☟︎
diana_coman: I'm actively looking for any reason why xhci should be allowed in
diana_coman: after reading around on this mess with the usb speeds, the summary + questions would be: 1. the dwc_otg seems actually specific to raspberry pi so I don't see how it's directly useful atm; am I missing something? 2. the manual/runtime pill so far relies on the companion mechanism to force a USB port down from "high speed" to "full speed" so basically from ehci to uhci/ohci; wouldn't it make more sense to blacklist ehci, xhci and whatever ☟︎
diana_coman: makes sense; how do I do that best on gentoo? still line in /boot/cmdline.txt ?
asciilifeform: diana_coman: interestingly, in my (conventional gentoo) userland, worked as posted ( i.e. with the newline )
asciilifeform: ( i've yet to find ~one~ pc board, of any vintage, with ttl ports )
mircea_popescu: asciilifeform is there some way to connect as a tty bypass the usb altogether ? i really dun wanna include usb if can be helped.
asciilifeform: ( the above is == to the 'Tip for Linux Users' item in http://nosuchlabs.com/hardware.html , which i listed as workaround for 'more than 3 pl2303' infamous bugola )
mircea_popescu: still tbh i'm kinda pleased with how this ratchet works. mystery meat in fg-machine interaction had to await s.mg to be found. item's been out what, years, undergone all sorta testing...
mircea_popescu: as in, "i checked, we don't have" or as in "we couldn't possibly have something this fucking stupid o oops there it is how the hell did it sneak in"
diana_coman: ah, that might explain why I haven't yet noticed it
diana_coman: that one I got even 8 times in a row there
diana_coman: asciilifeform, I get as I recalled this "[63939.499700] pl2303 ttyUSB0: usb_serial_generic_read_bulk_callback - urb stopped: -32" but I don't see the others, hmm
diana_coman: mod6, I'd say don't worry about it; as a rule though productive people do stuff, not as if they need to "say" productively things
mod6: i should have just ignored. typically I do.
diana_coman: asciilifeform, I certainly say the last line, don't recall the first 2 but I might have missed them
mod6: guy says '<douchebag> can I be upped? I have some productive things to say' in PM, and I think "hmm. alright"
a111: Logged on 2018-08-01 13:58 asciilifeform: i suspect an oddity with the linux tty subsystem. the Right Thing solution would be to find it. the alternative, ugly solution, is 1) 512 byte buffered reads 2) with timeout .
mircea_popescu: speaking of which, i wonder how that fellow's business/revolutionary/technico-theoretical/etc idea is faring these days.
asciilifeform: i'ma let mircea_popescu say, whether Right Thing is to start with (2) and proceed to (1), or straight to (1) .
asciilifeform: diana_coman: i confirmed ( coupla dozen shots ) hang only ever takes place on 1st read() after open().
asciilifeform: i ~would~ prefer a sanely-behaving OS. unfortunately i dun have one up my sleeve.
diana_coman: I'm going to dig around a bit more too to see if I can find any more clues of sorts
asciilifeform: diana_coman: i'ma have to do a detailed dig in re the linux tty thing. but this could take a while, and no guarantee of finding culprit in the 100s of MB of open sores liquishit. so you will need the buffer+timeout thing, i suspect.
diana_coman: but I'm not comfortable with not knowing wtf in there because it has the potential to blow up very nastily indeed
diana_coman: <asciilifeform> i suspect an oddity with the linux tty subsystem. the Right Thing solution would be to find it. the alternative, ugly solution, is 1) 512 byte buffered reads 2) with timeout . -> this is pretty much my current understanding as well
asciilifeform: ( observe, if tty ~does~ successfully open, can read 4evah, i had one dd going for 6 months without problem )
asciilifeform: note that FG outputs not only random bytes, but at random ~rate~ . currently i wonder if we've unearthed an 'impedence mismatch' in linux tty.
asciilifeform: i suspect an oddity with the linux tty subsystem. the Right Thing solution would be to find it. the alternative, ugly solution, is 1) 512 byte buffered reads 2) with timeout . ☟︎
diana_coman: but a. WHY don't I have same trouble on any of the machines here b. WHY does it hang anyway c. wtf do I do
diana_coman: hence my diana_coman> dd seems to be more resilient but I suspect it's mainly because it's not that sort of little&frequent
diana_coman: anyways, dd hangs *sometimes*, harder to pin down ; ftr I DID go and read the dd code too but I can't say I'm any wiser as to why/how it is more resilient
diana_coman: hm, I usually get that above 7, closer to 8
diana_coman: anyways, if you find something the matter specifically with eucrypt code, I'd be quite happy really since it's easiest to fix tbh
diana_coman: fwiw same tests of eucrypt ran perfectly fine on all machines I have around here with fgs
diana_coman: i.e. if you run the eucrypt tests 0 or 1 that read more they tend to take longer to get to the hang (although they still do eventually)
diana_coman: dd seems to be more resilient but I suspect it's mainly because it's not that sort of little&frequent
asciilifeform: ( fwiw i've dd's from dulap's FGs previously, with 0 signs of any problem )
diana_coman: aha; good to know at least it's not *just* that machine; might be worth to try replicating the dd hang as well , although by now I expect it will happen
asciilifeform: diana_coman: i've built eucrypt and replicated your hang
diana_coman: well, uhm, scratch that, I just got one of those stuck too, lol; it took longer to get stuck, nothing else
diana_coman: I start suspecting it's maybe something to do with short+frequent reads as weirdly enough tests that read 4096 bytes seem... fine
douchebag: My main problem with the Pizarro business model is that I could essentially get the same service by purchasing a fiber internet connection and hooking it up to a rockchip and then SSHing into it
douchebag: I just have not been enlightened on why my goals are "the wrong goals", the goals I'm working towards are going to help me feed my family someday and at the end of the day that is what matters to me.
ben_vulpes: i seee deaaaad people!
douchebag: Also the security firm I'm working on is expected to pull at least a half million dollars by december ☟︎☟︎☟︎
douchebag: I'm in AT&T Hall of Fame ☟︎☟︎☟︎
douchebag: ben_vulpes: I understand we disagree on that, however I'm trying to make money - I don't see how hosting rockchips that are overpriced is going to generate revenue in the long term.
douchebag: But yeah, I just wanted to let you guys know that I'm not a useless piece of shit. I've just been focusing on my personal projects, I've also gotten in a few more Hall of Fame's for some vulnerabilities I discovered.
BingoBoingo: This is IRC, I am pretty sure everyone here has at least a little bit of troll in their ancestry. Except for the transylvanians
douchebag: However, I have been working on creating a security firm
