asciilifeform: 'The newest Lexusesiv in particular have the most (Hashem-) forsaken hvac/audio computer systems WITH A MOUSE.' << lol!!!

asciilifeform: coming next: benjie-ignition-light-fireplace-or-light-cigar !1111

asciilifeform: ( async-with-handshake simply does 'if i don't get handshake, i won't send' )

asciilifeform: true synchronous bus -- does not.

asciilifeform: it still 'cares' what the baud rate is

asciilifeform: not same thing

asciilifeform: handshake (flow control)

asciilifeform: it is how , e.g., ps/2 kbd/mouse port worked. ( however it was never turned into a general-purpose item ) ☟︎

asciilifeform: 'synchronous serial' is simply a thing like rs232 but with 2nd pin, for clock, and then machine knows when to read off the bits.

asciilifeform: ( usb is not a 'serial interface' at all but a massive tub of liquishit, with bookcase-sized spec )

asciilifeform: incidentally it is imho maddening that pc never standardized a SYNCHRONOUS serial interface ☟︎

asciilifeform: it's a 'wtf, ent thinks pi equals 2, wat gives' tool.

asciilifeform: it is specifically for diagnosing catastrophically broken setup

asciilifeform: mod6: running these on items that already passed diehard is waste of time

asciilifeform: http://man.openbsd.org/ldattach.8 << try re flowcontrol on bsd

asciilifeform: and it'll pick up something with most of the 1s stuck on.

asciilifeform: every however many ppm

asciilifeform: if box is misbauded, it will pick up a byte solely by accident, when it gets something that looks like it has the start and stop bits

asciilifeform: yeah definitely b0rked

asciilifeform: ideally.

asciilifeform: gotta compare samples of ~same size.

asciilifeform: (prepare barf bag)

asciilifeform: now do it to what you got on the bsd box

asciilifeform: mod6: looks quite ordinary

asciilifeform: it is likely that you have one somewhere in the house already

asciilifeform: aha.

asciilifeform: even supposing desk ps supplied ideal dc -- still yes : length of path.

asciilifeform: the other factor, aside from ac mains ripple , is rf ( from the power path being of any appreciable length ) from environment

asciilifeform: by same token your comp is also 'ideal dc'

asciilifeform: (which has no physical means of rippling)

asciilifeform: which only comes out of battery.

asciilifeform: you want specifically guaranteed-nonrippling dc

asciilifeform: nope

asciilifeform: but asciilifeform has somewhat unusually clean (double-converting sinusoid ups) power

asciilifeform: fwiw i did a 1G of this on ~one~ particular unit and found no significant differences

asciilifeform: *minus

asciilifeform: ( be sure to tie together the battery-minux and the ground on the usb dongle )

asciilifeform: ( 6v is entirely ok )

asciilifeform: btw if mod6 wants a mega-useful sequel to his tests, he can buy a https://mobileimages.lowes.com/product/converted/008236/008236128024.jpg and try battery run

asciilifeform: y'know, the kind that drop specific octets.

asciilifeform does not recommend the histogram thing as a firstline test, it was written as diagnostic to ferret out broken os

asciilifeform: ok

asciilifeform: yes, but this did not tell me ~on what~

asciilifeform: http://btcbase.org/log/2017-06-01#1664123 << this ? ☝︎

asciilifeform: aite

asciilifeform: )

asciilifeform: ( 'fg plugged into usb hub powered from wall 5v plug, amd crapteron 7.7ghz running shithead linux' etc

asciilifeform: and how

asciilifeform: yes but where was the input collected

asciilifeform: plz to describe the entire setup

asciilifeform: these from linux or bsd ?

asciilifeform: cat /dev/whatever > foo.bin &

asciilifeform: if it happily hangs on for minutes, hours, days -- it probably works.

asciilifeform: and are getting liquishit.

asciilifeform: if your cat disconnects -- you have flowcontrol on.

asciilifeform: mod6: try plain old 'cat'

asciilifeform: you will see 'dragons in the clouds'.

asciilifeform: the perhaps worst 'test' ~of a working rng in particular~ is to look at the hex with naked eye

asciilifeform: but it helps to remember what the idea is.

asciilifeform: sorta the point of 'ent', 'dieharder', etc. is so as not to have to do these by hand.

asciilifeform: ( if there were, you would fail dieharder's 'birthdays' test at the very least. )

asciilifeform: nothing particularly interesting here.

asciilifeform: ^ expected values for count of a bioctet, in your case 'ff fd'

asciilifeform: !~calc 1190905856 / 65536

asciilifeform: !~calc 1372938752 / 65536

asciilifeform: !~calc 1095455232 / 65536

asciilifeform: !~calc 1095455232 / 65536

asciilifeform: mod6: still dealing with the bsd thing ?

asciilifeform: it is astonishingly tricky to get raw bytes UNMOLESTED into and out of a 'modern pc'.

asciilifeform: or line endings, etc.

asciilifeform: will reveal, e.g., 'smart,helpful' unix that drops 'in-band control' octets.

asciilifeform: ( histograms, you will want when trying to learn what it was that you broke in your setup )

asciilifeform: first test however is always 'ent', you can see in pete_dushenski's sample that ent immediately produces barf

asciilifeform: (numerically)

asciilifeform: and moreover, a quite different one each 1G

asciilifeform: a 1G , say, sample, should have nearly flat histogram

asciilifeform: mod6: usage -- ./hist.py foo.bin

asciilifeform: mod6: http://wotpaste.cascadianhacker.com/pastes/ihPkP/?raw=true ☟︎

asciilifeform: trinque: they dun have a wall plug ?!

asciilifeform: also the 'nsa not involved, shuddupterrorists' lulz.

asciilifeform: neato mod6

asciilifeform: ^ check out the photo of judge !

asciilifeform: meanwhile, in monkeystan, https://archive.is/moE9o >> 'The ruling found no legal grounds for reversing Ulbricht's conviction or 2015 sentence for founding and operating Silk Road' << BingoBoingo / qntra ?

asciilifeform: ~one~ possibility.

asciilifeform: aha yes

asciilifeform: 'where were you when he was alive'

asciilifeform: 'one round for each of 8 dead sons!' or how it went.

asciilifeform: anyone recall description of old woman who fired revolver into (already long dead, hanging upside-down) mussolini ?

asciilifeform: aha.

asciilifeform: whether lenin, saddam, whoever. nothing pissant, esp in a crowd, loves more than to throw down symbol of ~his~ utter insignificance

asciilifeform generally barfs at photos of 'pulled down statue' given as they figure prominently in orangerevolutionary material, of pissants kicking dead lions

asciilifeform: tru

asciilifeform: well lincoln's empire not yet rm -rf / 'd yet

asciilifeform: other than the gigantic monster one in the capital

asciilifeform: funnily enough, not so many lincolns in usa

asciilifeform: just as i will find turning over washington statues satisfying, if i live to partake of it

asciilifeform: statues don't fight back, either

asciilifeform: so much easier to turn over a statue than to actually accomplish something other than being piece of shit

asciilifeform: hey, the ukrs TO THIS DAY haven't run out of lenins to topple

asciilifeform: aaaah suure.
