asciilifeform: afterwards can go to new tenant.
asciilifeform: mod6: recall, that one he asked to let be until expires
mod6: The one that mircea_popescu rented for douchebag doesn't expire until the 19th iirc. I'll update you on that one. Unless mircea_popescu says to nuke it ahead of time.
BingoBoingo: mod6: There's the douchebag one as well. I am waiting on alf to give the order before I touch either of them.
mod6: But anyway, let me know if you need to know which one is his -- there are notes in the message I sent around couple days ago.
mod6: Well, it is august, UTC time. Maybe wait until tomorrow in case he changes his mind.
mod6: BingoBoingo: You may, at your earliest convenience wipe the Rockchip that mats was renting.

asciilifeform: ( how exactly this ties the hands of, e.g. , taiwanese fabs, i do not presume to know , but result is evident )
asciilifeform: i've turned up some hints that usg actually interferes with the ADC makers -- 'ohnoez, moscow could use fast ADC in radar set'
asciilifeform: i.e. are pressed shitboard , rather than hardwood.
asciilifeform: and they ~all do shenanigans with multiple slow ADCs masquerading as 1 fast one
asciilifeform: doubtful, all of the examples i've been able to peek into, are full of xilinx.
mircea_popescu: possibly firmware of one could be rewritten, liberating the item and saving you a coin
asciilifeform: ( in this context, 'sane' ~= sits on pcie bus, and ADC turnaround is fixed # of bus cycles, preferably 1. and documented i/o. )
asciilifeform wouldn't consider , say, 1btc , for a ~sane~ scope, to be unreasonable
asciilifeform: so if you want a 1G/s scope with os where you actually have some control of the timing ( for e.g. real time phase sampling ) you're 100% phuqed.
asciilifeform: ( these, for extra laughter, come with ~built in windows~ in the instrument itself ! )
asciilifeform: not the 250k agilent either.
asciilifeform: mircea_popescu: note, not in the i-dun-give-half-a-fuck-what-it-costs market, either
asciilifeform: sorta hilarious , this, 'here's pc with very spiffy 6G/s pcie bus, for 100$, but if you want to connect something useful to that, haha, what do you think this is, the fyootoor'
asciilifeform: in other noose, since 1st time i asked the q in 2013, appears that there is ~to this day~ not such a thing as a 1Ghz oscilloscope with any linux support whatsoever.
asciilifeform: ( tho perhaps, a FG with only 1 rng plugged in, could be a 'fuckgoat' )
BingoBoingo: Will have it ready <diana_coman> BingoBoingo, do you know whether smg main server has the black snake cables or what? << It does.
BingoBoingo: <diana_coman> BingoBoingo, do you need me to shut down the box? << I will if you want me to pull it to swap cables.
diana_coman: thanks, I'm off to sleep
asciilifeform: ok , should suffice for test, i'ma report tomorrow .
diana_coman: it ~always hung before finishing the 11 runs even
diana_coman: asciilifeform, that's literally what ended up as main test because convenient: it attempts to generate 11 "dirty float" random numbers using 4 random octets from fg; first number there is number of repetitions; second number chooses what test to run (if you run only ./tests 11 without 2nd number it will print the list of what it knows to do)
a111: Logged on 2018-07-31 15:49 diana_coman: asciilifeform, yes, get eucrypt and run the tests for smg_rsa, something like ./tests 11 11 (i.e. 11 times test no 11)
asciilifeform: diana_coman: is http://btcbase.org/log/2018-07-31#1838330 an exact description of the test ? ☝︎
asciilifeform: i'ma test on dulap also, it has identical fg/cabling setup to primary s.mg box
diana_coman: and I can't really reset that
diana_coman: asciilifeform, on smg main server I ran only dd although I never had any problems nor wobbles nor anything with the fgs there
asciilifeform: rather, ruled out as primary cause, could easily be the ultimate barf source in conjunction with 1 / 2
asciilifeform: the possible suspects , so far -- 1) ttl dongles 2) hub 3) musl userland , somehow
diana_coman: BingoBoingo, do you need me to shut down the box?
diana_coman: also, the fact that dd *also* hangs at time there is a big red flag
diana_coman: sadly I don't know of any replacement to suggest, no
asciilifeform: ( the 2 constraints -- 1) ~not ever ftdi~ 2) no flashable chips plox )
diana_coman: and other than the weird fact that read simply blocks randomly, I don't know
asciilifeform: diana_coman: ftr i am still on the lookout for anything like a practicable replacement for pl2303
diana_coman: a bit of reading on this famous pl2303 does suggest all sorts of "hanging" issues but I haven't found anything clearly applicable so far
diana_coman: asciilifeform, I doubt it's the cables really but can't hurt to rule that out
asciilifeform: diana_coman: i'm gonna try and replicate here in the torture room, with your proggy -- i have both cable types here
diana_coman: right, I'm anyway currently in need of a break and at a loss otherwise on this; so BingoBoingo at your leisure, please change the cables and leave only one FG plugged in for now; I'll get some sleep in first, so there's no hurry - anytime within next 10 hours works fine
asciilifeform: BingoBoingo: 'blue' is theoretically same chip, but from a diff chinese seller ( fwiw asciilifeform's desk FG operates from a 'blue' )
a111: Logged on 2018-07-31 19:57 diana_coman: asciilifeform, that tip says problems handling more than 2 but I have...2?
asciilifeform: http://btcbase.org/log/2018-07-31#1838486 << i've only ever observed pl2303-specific headache when 3+ operating ( and even then , consisted of slow, rather than halted, signal ) ☝︎
asciilifeform: i was about to suggest, to swap both cables , see if these can be ruled out
diana_coman: BingoBoingo, do you know whether smg main server has the black snake cables or what?
diana_coman: hard to say if that is more than a glitch or not though
diana_coman: well, doing stty -F /dev/ttyUSB1 first so far (2 times, so machine rebooted in between...) at least had dd going well
diana_coman: hm, before switching cables I can switch order of init and see if there's any difference anyway
a111: Logged on 2018-07-12 14:06 BingoBoingo: On this box one of the FG cables is the blue guy that came with my personal FG, the other is the new style black snake
BingoBoingo: Well, one other thing we can do is switch one or both usb ttl cables. As mentioned earlier one of the cables is the "blue" style that shipped with earlier FUCKGOATs http://btcbase.org/log/2018-07-12#1833809 ☝︎
diana_coman: as it is, it will have to wait until tomorrow anyway as atm I'm a bit at a loss wtf
diana_coman: BingoBoingo, wait a bit, at least to know if there is something else to try if you go there
BingoBoingo: <diana_coman> BingoBoingo, how long would it take to get there and unplug one of the FG to have a test with only one? << I could go there and be back witing an hour
diana_coman: BingoBoingo, how long would it take to get there and unplug one of the FG to have a test with only one?
diana_coman: basically as the "wobble" initially reported: if only one fg is set, then first read via dd hangs just the same
diana_coman: at any rate, updates so far are relatively few: can't reproduce it on different machine (though I still have a few to test...); it IS easily reproduced even with dd on smg test server
diana_coman: asciilifeform, that tip says problems handling more than 2 but I have...2? ☟︎
BingoBoingo: The bigger wtf is what did they need a police force for? Place is clearly sized for a part time constable or two.
asciilifeform: 'their poorly fitting bulletproof vests are beyond their expiration dates' << lolwat
asciilifeform: btw also worth trying the item listed in 'Tip for Linux Users' at http://nosuchlabs.com/hardware.html .
diana_coman: at that time I did not yet have the boot-time sh init though; I suppose I can add this to test sheet
diana_coman: if anything, it would suggest that even dd can choke there
a111: Logged on 2018-07-12 13:49 diana_coman: asciilifeform, BingoBoingo access to box & config confirmed; FG on ttysUSB0 had a wobble at first and I don't understand why: I ran the stty -F /dev/ttyUSB0 115200 raw -echo -echoe -echok and then tried dd iflag=fullblock if=/dev/ttyUSB0 | hexdump -C but nothing came up; then I ran the stty on usb1 as well and tried again and it...worked; any idea wtf was that at first?
diana_coman: asciilifeform, btw there was this: http://btcbase.org/log/2018-07-12#1833792 ☝︎
asciilifeform: good % of unixland, by weight, consists of this.
asciilifeform: 'if i actually fix it, would have to admit that it was buggy'
a111: Logged on 2016-08-27 15:03 mircea_popescu: "if i make it what i think it should be it crashes"
mircea_popescu: but imo this correct behaviour was elided specifically because http://btcbase.org/log/2016-08-27#1530346 reason, ie "our permission model is fucked, if we do a close-before-open it makes it too obvious" ☝︎
asciilifeform: afaik to this day no such provision in any unixlike.
asciilifeform: ( naturally the imbecile kernel doesn't actually test whether something is riding on the tty prior to opening, 'why would we' )
asciilifeform: mircea_popescu: happened to me '9000' times when testing FG, and earlier iron.
mircea_popescu: asciilifeform it's happened to me.
asciilifeform: btw if anyone wants to experimentally observe the zombie effect, can do it with ordinary gnu 'screen' -- when opened on a tty with blocking i/o, will routinely leave zombie turd instead of properly terminating, then hours later you find that tty is wedged, and discover 9 copies of 'screen' in process table.
diana_coman: I thought Dr A said that of you actually!
diana_coman: mircea_popescu, ahaha dadatroll; but now I see why it didn't even ring a bell at all as I probably missed the comments section there/didn't follow it
diana_coman: BingoBoingo, will do, thank you;
asciilifeform: if diseased mind fails to produce impulse to visit toilet instead of filling own pants, then yes, work with.
mircea_popescu: that's more of an absence, see. generally psychiatrists don't attempt to work with what the diseased mind fails to produce, but instead focus on the positive malfunctions, the productive sort. "tell me more about the little gremlins"
asciilifeform: somewhere near the top of the list, right below 'gotta check EVERY system call for failure erry time in user coad'
mircea_popescu: in fact, the concept of "zombie" is perhaps the most indicated ear of stupid to shake the whole echafaudage by.
asciilifeform: mircea_popescu: the astonishing bit isn't even that system5 unix had this nonsense, but that the linux derps faithfully re-created it.
mircea_popescu: zombie is not just (as an inexistent, imaginary "manual" mentally reconstructed from the pile of gunk they published purports to hint) an entry in the table to permit the caller to clean up correctly. it is ALL SORTS of things, and generally of the getting in the way kind.
a111: Logged on 2018-07-31 16:15 asciilifeform: unix i/o is retarded, if blocking read blocks, it gives you a zombie process , and the next process you start that tried to read same tty, will also become zombie
mircea_popescu: http://btcbase.org/log/2018-07-31#1838388 << this. ☝︎
BingoBoingo: <diana_coman> basically if I don't manage to reproduce it on any other machine, it would seem it's potentially to do with that specific system << Let me know if you want a pair of hands.
mircea_popescu: now i'm stuck re-reading all that... and esthlos thinks he has fucking problems. wait until you learn romanian, buster.
mircea_popescu: (the above, for the rotaku club, is a pinnacle of intertextual metatextuality the likes french culture barely ever managed, and anglonline never did.)
mircea_popescu: rotate plug pi rad and try again!
diana_coman takes a break from the usb reading wtf
phf: diana_coman: we will take credit for it (also we'll take retroactive credit for the frequent mysterious reboots of asciilifeform's machines)
mircea_popescu: diana_coman do you recall that lulz btw ? "nu-i ardelean, n-are rabdare adevarata, ii emulata-n soft"
diana_coman: I honestly thought that was the main part of phf's joke there : the "control without dominate" in the spirit of modern times
phf: henceforth any attempts to expose the activities of the secret society of illuminated fraudsters shall be denounced as a ravings of delusional paranoids
phf: mircea_popescu: to be honest i didn't read into it past the roleplaying humor, but upon immediate reflection, your objection makes equally obvious sense
