asciilifeform: BingoBoingo: and disk.
asciilifeform: granted i haven't unearthed any direct evidence that uy1 is physically sad, of yet. but imho this is Right Thing.
asciilifeform: BingoBoingo: plox to lemme know when ready, ty
asciilifeform: BingoBoingo: ~in addition~, rather than in place, of their current service, if it wasn't clear
asciilifeform: (4 cpu cores)
asciilifeform: indeed can, it's a quite substantial box despite appearances.
asciilifeform: they can put e.g. their znc there, at their option.
asciilifeform: BingoBoingo: i am thinking : let's consider giving all uy1 users an acct on the idle rk , until uy1 is replaced and moved to cold spare.
asciilifeform: lobbes: 4th was with my own hands, new kernel emplaced
asciilifeform: guten morgen mircea_popescu hanbot et al
asciilifeform: meanwhile, box is up without any interesting observations
asciilifeform bbl
asciilifeform: leaving the temp/voltage/etc item running ( and will run until further notice . )
asciilifeform: BingoBoingo: i'ma also sleep shortly, will letcha know if i wake up screaming with a wtf
asciilifeform: mircea_popescu: incidentally asciilifeform nao has the necessary optics that for e.g. 'FG2' and fyootoor products, we can include signed board photos.
asciilifeform: i reflashed'em for good measure.
asciilifeform: they show no signs of molestation, not only work to spec but rom untouched.
asciilifeform: incidentally manifest actually includes 2 FG units ( pizarro-owned ) . i had to fly'em back in april , if anyone recalls, cuz of ben_vulpes's misadventure where they were pawed by orcs for whole night
asciilifeform: ( i suppose technically this is 4th expedition -- BingoBoingo orig pioneer, and then ben_vulpes . but asciilifeform's 2nd. )
asciilifeform: there's a list of itches that needs scratching and it got longer today.
asciilifeform: mircea_popescu: acceptable for nao , but i'm inclined to make 2nd expedition sooner rather than later.
asciilifeform: ( why needs gear ? because can flash even nao, but you want to get orig rom contents ~out~ 1st, for a good looking at. and then there is 'unbrick' event also. )
asciilifeform: it is on the cargo manifest for 2nd.
asciilifeform: mircea_popescu: i do. i actually bit my elbows after 1st expedition, that i did not include the necessary gear for this in the 1st crate.
asciilifeform: ( going forward, http://btcbase.org/log/2019-01-14#1886856 ) ☝︎
asciilifeform: mircea_popescu: box runs asciilifeform's kernel as of 9hr ago.
asciilifeform: i'd much rather folx did those on rk's..
asciilifeform: interesting
asciilifeform: insert typos ?
asciilifeform: there's the 'what used for' q also. i'm still at a loss, i'll admit, re what is to be gained even from root on a box hosting blogs.
asciilifeform: i recall there was a piece where mircea_popescu threw out a raid card
asciilifeform: mircea_popescu: what do you typically do with yours ? throw'em out after 1 peculiar reset ? 2 ?
asciilifeform: cuz that's a perfectly valid q.
asciilifeform: i'd like not to lose the orig thread, re whether box was interfered with.
asciilifeform: i thought we were discussing the outrageous howler that 'dc would warn if 1 box in a 42u has 1 chip 40c over temp'
asciilifeform: ?
asciilifeform: mircea_popescu: how wouldja distinguish via 'flow of air from rack' 2 cpus at 50c ea. vs 1 at 0 and 1 at 100.
asciilifeform: and the halon gets pumped.
asciilifeform: mircea_popescu: that'd be for ambient air. if yer ambient atmosphere is 70c, this is called 'room on fire'
asciilifeform: mircea_popescu: 'is 3 tonne auto here or not' is very diff problem from 'what temperature is the red hot nail inside this 30kg crate'
asciilifeform: BingoBoingo: do they log these somewhere ? how didja learn of it
asciilifeform: overheats when, for instance, 100cc/sec of air is being moved when wants 300.
asciilifeform: ( and if this wasn't part of the deal you had with'em, oughta have a stern talk )
asciilifeform: mircea_popescu: if a dc were able to warn you re overheating cpu, they had root on yer box.
asciilifeform: aimed at what ? the outside ? you'd need a bomb calorimeter and whole thing in transformer oil, to stand any chance of distinguishing a frying cpu from a working one through closed chassis
asciilifeform: laser?!
asciilifeform: ( and a cpu is a ~1g thermal mass. )
asciilifeform: an overheated cpu is only 50c away from a working one.
asciilifeform: yer speaking of 'rack is on fire' case.
asciilifeform: what's the temp 1m from a hot iron ? ~room.
asciilifeform: it wouldn't
asciilifeform: dc has nfi what temp is inside our box
asciilifeform: waiwaat
asciilifeform: what did it look like ?
asciilifeform: BingoBoingo: didja happen to photo the internals when you opened ?
asciilifeform: box runs till it doesn't, then behaves rather like this.
asciilifeform: mircea_popescu: never had a clogged fan on your watch ?
asciilifeform: mircea_popescu: keep in mind this was a ben_vulpes-baked box, i never saw inside of it ( dulap-III, dulap-spare, s-mg, s-mg-spare -- i cleaned with own hands )
asciilifeform: not necessarily stopped, but obstructed
asciilifeform: imho mle is still thermals.
asciilifeform: mircea_popescu: 3 unsanctioned, 1 planned reset
asciilifeform: mircea_popescu: jury's still out
asciilifeform: ( or it wouldn't come back up. )
asciilifeform: they aint always visibly burst, but i'm inclined to think this wasn't the caps.
asciilifeform: http://www.loper-os.org/?p=1871 << typical example of when caps.
asciilifeform: and 10yo caps etc
asciilifeform: ssds are new, no one buys used ssd, it'd be like buying used toiletpaper
asciilifeform: mircea_popescu: disks
asciilifeform: ( can't speak for colo subscribers such as trinque , referring to pizarro irons )
asciilifeform: mircea_popescu: 100% of the x86 iron in the cage is 2009-11 vintage.
asciilifeform: and disks yes
asciilifeform: the only new iron in the cage is the rk's.
asciilifeform: nope
asciilifeform: ( why -- i do not know. but ram appears to age, possibly ion migration )
asciilifeform: ram, typically
asciilifeform: i have
asciilifeform: i dun currently have any notion of knowing what, precisely , failed
asciilifeform: this is a case where '1024 chickens' wins
asciilifeform: but indeed i'd much like to move to a 'near-errybody on rockchips' , ~these~ can approximate the ideal of 'treat irons as toilet paper, discard on 1st sign of rot'
asciilifeform: i haven't succeeded in crashing a rockchip yet ( outside from the rotting usb ssd's affair )
asciilifeform: the sad part tho is that if asciilifeform threw out erry retardix box that ever kernel panicked, would have none left in service
asciilifeform: mircea_popescu: i can't disagree, and am inclined to move it to cold spare when we get another crate in.
asciilifeform: mircea_popescu: fwiw crashism is more typical result of failed diddling than working.
asciilifeform: mircea_popescu: this q can be asked re any box.
asciilifeform: my fiber has 5-10 minutes of outage in a year, and ~that~ palpably suxx
asciilifeform: !#s how many bugs tolerate
asciilifeform: outages suck, period
asciilifeform: BingoBoingo: it's in the log
asciilifeform: hanbot & other subscribers to uy1 : plox to inform asciilifeform asap if you notice ~any~ unusual behaviour on this box ( not only reset , reset will be obvious from here )
asciilifeform: hanbot: today i set up realtime stream of system log + voltages + temperatures + fan rpm to the torture room, was expecting to find thermal problem, so far 0
asciilifeform: hanbot: we dun know yet wtf reset the box ( and it happened no fewer than 3 times, in 2 day span )
asciilifeform: been up continuously since i set up sensors earlier today, and still alive, with 0 anomalous readings
asciilifeform: box is still up
asciilifeform: hanbot: when was 'this' plox ?
asciilifeform: shinohai: neato. what didja do re trb ?
asciilifeform: shinohai: nifty eulora piece. yer ahead of asciilifeform in that battlefield, i've yet to attempt building eulora
asciilifeform: ohai shinohai
asciilifeform: 'that is not dead which can eternal lie..' or how did it go.
asciilifeform: meanwhile, in darkest lulzafrica, 'Today we’re happy to announce that Urbit’s address space, now called Azimuth, is live on the Ethereum blockchain... We want Urbit to be a reliable, durable, permanent computer that’s simple to use. Today Urbit is still a prototype, not a consumer product. But we’re making great progress' ☟︎
asciilifeform: imho if satellite 'oops it crashed and i cant tellya why', designer oughta get a 1way ticket to its orbit to go and debug..
