asciilifeform: (which happily lives in 'harem' of up to 32 iirc.)
asciilifeform: if you run 1socket rigs -- them
mircea_popescu: neways. moral i guess being, stock up on above fxen, they're great and quite possibly the last good chip in human history.
asciilifeform: i get'em used, because they are ~indestructible. but yes.
mircea_popescu: so yeah, this was top of line in 2009.
asciilifeform: (must point out, though, opteron was not a cheap-side chip, and the mobo that ate it -- also was not, was top-of-the-line in amd world)
mircea_popescu: i guess if you bought it when it came out the opteron was like 1k or some shit.
mircea_popescu: as i somehow doubt you spent 2k to build that box in 2009.
mircea_popescu: ah. yes i guess 2016 apple laptop compares favourably to cheap-side 2009 desktop.
asciilifeform: ok to be perfectly clear, i compared 2 boxes, one -- the aforementioned crapple, one -- a 2x2393SE.
mircea_popescu: i thought you said...
mircea_popescu: i7 4870 was released mid 2014 ; the amd mid 2013 if memory serves.
mircea_popescu: the amd is about 6 months OLDER than your intel.
asciilifeform: but gotta compare to same-period comp.
asciilifeform: and yeah lappy is to actual comp as sapper's spade is to excavator.
asciilifeform: the crapple is ~impossible to do anything serious on. wtf, gdb
asciilifeform: (behind schedule , behind 3 other things!)
asciilifeform: i realized that this is comical a while back and started building a new 'toilet' box , but it isn't done yet.
mircea_popescu: "oh, it's better in this thing i dont use"
mircea_popescu: so then wtf.
mircea_popescu: whereas the i 4870 has ddr3 1600
asciilifeform: the one where one box has ddr2 and the other ddr3 possible.
mircea_popescu: dude... explain what singularity you live in where a half the bus clock half the cores half the cache ONE QUARTER POWER chip is still, somehow, better.
asciilifeform: sadly this is not so in practice.
mircea_popescu: so then. you probably need a dozen bridged crapples to touch the amd box.
mircea_popescu: twice the cache, twice the cores, what the shit are you on about.
mircea_popescu: phenom is 2x that bus, ftr.
mircea_popescu: oh come on. what's in the crapple ?
asciilifeform: as for the crapple, it has roughly half of the cpu horse as dulap.
asciilifeform: also to be absolutely rigorously correct, 'phenom' series ~could~ be coaxed into using ecc ram, but only 'unbuffered' variant (so no 16-stick monster rig). what it wouldn't do is to run in multisocket mobo (which is what i use)
asciilifeform: and no, unfortunately it does ~not~ beat the 2016 crapple.
asciilifeform: so what mircea_popescu just recommended was 'buy the same box that was too slow, but sans ecc'...
asciilifeform: what it is, is the konsoomer version of the opteron i actually have in the box i am sitting on nao!
deedbot: davout updated rating of jurov from 3 to 4 << met IRL, does what he says he will do.
mircea_popescu: so then wtf holy shit omfg.
asciilifeform: (neither is the crapple)
mircea_popescu: like what ? something like amd fx 9500 is, i bet, way ahead anything apple ever put in anything they made. ☟︎☟︎
asciilifeform: (all of my full-sized mircea_popescu-style comps are 'bearded', this comes with using pre-obummer amd iron.)
asciilifeform: i should add, the crapple was also the fastest box i had available locally.
mircea_popescu: laptops aren't computers. they're not even female computers, they're toy computers.
davout: mircea_popescu: finding memory leaks? uninitialized memory accesses etc? helps when teaching oneself c++
mircea_popescu: you're the worst sort of engineers, i swear, the kind who calculate tomato production of balcony and are proud to wash their teeth with a motorcycle engine adaptation contraption.
mircea_popescu: why the everloving would you valgrind on a laptop ?
asciilifeform: davout: anything that uses debug hooks, catches fire & dies
davout: asciilifeform: didn't experience that, what i did experience was "oh no, can't install valgrind because fuck you"
mircea_popescu: they're insane if they seriously imagine their tivo dumbassery has better chances this time around. but w/e, they DO imagine.
asciilifeform: i shit thee not
mircea_popescu: i dunno, they had to make space for java machine ?
asciilifeform: mircea_popescu: phun phakt, i replicated phuctor on a mac lappy (it happened to be the one in the room with sufficient free disk) and it works -- except that apparently gdb no longer works on latest crapple os ☟︎☟︎
mircea_popescu: in the "but do you know who mai father is and why is hybrid mini not also boatcar!!1"
asciilifeform: e.g., knowing how much power, to the microamp, victim is drawing; or time; etc
mircea_popescu: more than one mactards threw hissy fit becase "I R HAS GOOD LAPTOP" "dude... it sucks, we can't tell you that it sucks politely, BUT IT DOES."
davout: yeah in the sense be on the same box, or physically close
asciilifeform: davout: side channel isn't magic, you gotta actually ~have~ the side channel
davout: asciilifeform: none in particular while discussing trb, "trb uses openssl, which is vulnerable to side channel attacks" came up
mircea_popescu: anyway, major point here being "how expensive" is not a good criteria for card. either dig up in the specs or use the cards ppl runnign the thing ask you to
Framedragger: ah yeah. there was an old 3g modem plugged into internal pcie, i removed it. pretty lulzy
asciilifeform: if you are willing to work with an open arse
asciilifeform: the other 'abuse tool' you can get is internal pcie to external slot snake
Framedragger: (i want to connect my x220 which does not have thunderb0lt)
mircea_popescu: yeah pcie is becoming quite the proverbial tower of piles.
Framedragger: asciilifeform: k, good to know, thanks. it's just one bus lane afaict (pci express x1), ExpressCard 2.0, so 'double' the bandwidth i take it. 4-5gbps total
asciilifeform: Framedragger, mircea_popescu : apparently nowadays you can buy 'thunderbolt' to pcie expanders, if the machine has this plug. (i have not tested this variant.)
a111: Logged on 2017-01-06 11:19 davout: asciilifeform: was there a thread re the side-channel attacks on openssl's ecdsa signature?
asciilifeform: http://btcbase.org/log/2017-01-06#1597368 << more than one thread. ~which~ side channel are you interested in, davout ? ☝︎
a111: Logged on 2017-01-06 12:42 Framedragger: OT, anyone's done an egpu rig on an x220? i'm probably gonna do an abonimation, and connect an nvidia card to x220 via its expresscard slot. there's this antichrist-like adapter (http://www.hwtools.net/Adapter/PE4C%20V2.1.html) which does the magic. bottleneck is expresscard (5 gbps or somesuch) but if one uses external monitor, it's all pretty good apparently.
asciilifeform: http://btcbase.org/log/2017-01-06#1597384 << i used a similar device to connect fpga card to thinkpad, coupla years ago ☝︎
Framedragger: right, i can see how that can be bundled up into a business product.
mircea_popescu: and yes i have. not particularly portable, but at some point people in $not-mentioned were offering "plug your laptop into the monitor" style videoconferencing
mircea_popescu: well, the bus becomes congested, it's not really designed to bridge north and south like that.
Framedragger: (changing countries come this summer)
Framedragger: ever done something like that? :) portable rig is portable.
Framedragger: aha, otherwise too much bandwidth gfx card <-> cpu apparently
Framedragger: (not worth if you have a really high end gfx card tho - waste of money)
Framedragger: OT, anyone's done an egpu rig on an x220? i'm probably gonna do an abonimation, and connect an nvidia card to x220 via its expresscard slot. there's this antichrist-like adapter (http://www.hwtools.net/Adapter/PE4C%20V2.1.html) which does the magic. bottleneck is expresscard (5 gbps or somesuch) but if one uses external monitor, it's all pretty good apparently. ☟︎
mircea_popescu: it MAY BE that the muslim wave actually improves female livestock on the old & wrinkly continent.
mircea_popescu: in other "muslim invasion" lulz : http://ask.fm/QueennnNAL ; now we play the game where you find me aryan malmo resident as hawt.
deedbot: lies, I tell ya!
Framedragger: it's a well known fact that an unbalanced high number of parentheses results in irc ping timeouts.
mircea_popescu: you'd think.
jhvh1: Framedragger: The operation succeeded.
Framedragger: !~later tell gabriel_laddel_p "I cannot presently maintain a connection to IRC." << get a bouncer ffs. ping me if you'd like a free one
davout: which, incidentally, seems like yet another very good reason to fully exfiltrate the wallet
davout: from where i stand it seems to me that trb would be vulnerable to it when signing transactions
davout: asciilifeform: was there a thread re the side-channel attacks on openssl's ecdsa signature? ☟︎
Framedragger: from glyf.org source, '<meta name="ICBM" content="39.083611, -77.148333" />' << rockville town square, ~15mi north of washington, dc :p
ben_vulpes: i'm not particularly bent about the sorting, 'twas simply what made me look at the linked stanzas in curiosity. curious about "what of it", as you say.
mircea_popescu: anyway, the problem of "how to sort two patches which alter entirely disjuncts subsets of the file set" is not exactly clear. unless they declare how they prefer to be sorted. ☟︎
ben_vulpes: yeah i'm in the same boat.
mircea_popescu: i recall this being proposed but im not sure if it ever was accepted.
ben_vulpes: notion, iirc, was to make a "release" vpatch that added *something* to *every file in the tree* to neck the patch graph down
mircea_popescu: so there's a version comment there, what of it ?
mircea_popescu: i'm not proposing it as a solution ; i'm not even sure exactly what you're talking about. just lulzing to self.
ben_vulpes: you advocated this at one other point too, right?
mircea_popescu gives it even odds this ends up with a "include prev hash in comments in files".
ben_vulpes: not inverted, as far as i can tell it's a fine place in the flow for it to be. i'm a bit discomfited, and am poking an old thread about "release vpatches" that seems to have surfaced unexplainedly in the makefiles vpatch
ben_vulpes: eh, the leaving of free money on the ground baffles me. ☟︎
mircea_popescu: but as to the other thing, i'm not sure i follow. your v inverted patch flow ?
ben_vulpes: also what's the deal with these single-tx blocks http://logs.bvulpes.com/chainstate#46
ben_vulpes: open topic for when folks wake up i suppose.
