asciilifeform: TheNewDeal: nope. just read a little about the lock.
TheNewDeal: asciilifeform how did you know about chicago elevators? Is that were you reside? I'm working in Chicago for the next week...
asciilifeform: missile lock is ceremonial item. in both american and russian procedural manuals, one turn-key is instructed to compel the other by force of arms if he refuses to carry out his half of the ritual.
decimation: Because you know the weak link in your undrground missile silo with 10 ton doors is ... the missile launch lock
decimation: there was some dumb tv show like pawn stars or something like that where some guy was trying to sell a "missile key" for $30k if I recall
asciilifeform: apparently, this is a famous lock.
asciilifeform: because now we have the net.
TheNewDeal: mircea_popescu I've been trying to find a list of premine / scamcoins that you provided in the past. It was in a wikipedia format. Can't find it in the logs
mircea_popescu: (which, btw, is STILL to this day not fully unwound)
mircea_popescu: and so was a major vault hoilding trillions worth of paper.
mircea_popescu: pankkake, the "if both your house and your bank burn down you don't care" theory is pure nonsense.
mircea_popescu: ;;later tell bitcoinpete "He fleeced -assette extraordinaire kakobrekla for 145 BTC" doesn't seem an accurate rendition. iirc usagi sold pirate insurance, which he paid up on.
decimation: implementing a turing machine would just re-invent the cpu model
decimation: Yeah I guess you can wire the address lines for the input to link to the outputs you want to simulate
mircea_popescu: <TheNewDeal> mp actually helped design that? didn't know he had that know-how << i'm really good at piggybacking on people's work.
TheNewDeal: I'm going to go enjoy a smoke and ponder that thought
decimation: yeah I guess you can just craw through its contents turing-machine style
asciilifeform: (if you can't see how, think for a minute)
asciilifeform: decimation: the most basic 'jungle fpga' is just your ordinary ROM.
TheNewDeal: now I understand why that crazy comp science teacher told me I had it easy
decimation: Also I found this amusing link: http://blog.notdot.net/2012/10/Build-your-own-FPGA
TheNewDeal: I though the card sorter was the actual machine that computed, no>
asciilifeform: (with the 'card knife,' which came with the reader.)
asciilifeform: card sorter - so you don't have to kill the fellow who dropped a deck.
TheNewDeal: oh my gosh, just talked to t his electrician the other day that told me he used to do maintenance on card sorters, like IBM's 074. Just thought I'd toss that in on the topic of old hardware
asciilifeform: (not discrete switches, at the end, naturally - rather, 'bit-slice' logic)
asciilifeform: decimation: until the late '70s, all cpu designs were of this kind
decimation: the idea of swapping out a card in your CPU is amusing to me
asciilifeform: afaik they still have it in a closet somewhere.
assbot: D-17B - Wikipedia, the free encyclopedia
decimation: your last comment about discrete logic lead me to research the topic: http://en.wikipedia.org/wiki/D-17B
asciilifeform: mp provided a reason why to do it. and useful tips on related subjects.
TheNewDeal: mp actually helped design that? didn't know he had that know-how
joecool: i have no idea what my keyboard controller is capable of anymore, so yeah points totally valid
assbot: Loper OS » Trilema 2014
decimation: ah yes it's related to that
asciilifeform: TheNewDeal: i built the rng. yes, it is only one of the components.
TheNewDeal: or perhaps that was just one component?
TheNewDeal: I thought MPEX's NSA was developing some RNG
asciilifeform: TheNewDeal: it's about the basic question of what it means to trust a machine
TheNewDeal: is this about the NSA dealio?
asciilifeform: just as not all things which aren't poisonous are good to eat for dinner
asciilifeform: (not that anything which passes this test is automatically worth using)
asciilifeform: decimation: i'll helpfully point out where this line of thought ends: if you can't re-create the device in its entirety from the published docs, it isn't worth using.
decimation: the next problem: they have an auditable RNG, but how do you know they are actually using it?
asciilifeform: decimation: there is no arcane secret in building a decent analogue rng.
asciilifeform: $100k if you know a fellow who owns the above and trust him.
asciilifeform: decimation: now the cost of auditing device becomes $10mil.
decimation: when you think about it, that's pretty silly, considering how easy it would be to use an analog noise source
asciilifeform: decimation: pretty much everyone fucks the goat right off the starting line - by using a vlsi rng
asciilifeform: decimation: if it did, i'da bought it, and wouldn't be trying to build
decimation: ascii does any commercial device you know about meet this criteria?
mircea_popescu: so what is to gain from this jerking in this circle as opposed to others?
asciilifeform: aside from this, even a hypothetically impregnable seal is an attack against the owner (he cannot examine the package either)
gribble: Ne me touche pas - French - English Translation and Examples: <http://mymemory.translated.net/t/French/English/ne%20me%20touche%20pas>; arrete,arrete,ne me touche pas. - YouTube: <https://www.youtube.com/watch?v=lcnPxgoZLNw>; PATRICIA CARLI 1963 Arrête, arrête, ne me touche pas... - YouTube: <http://www.youtube.com/watch?v=3KI236fMxoY>
mircea_popescu: ;;google ne me touche pas
decimation: if your crypto wasn't designed to defeat someone who knows everything about how it works, then you are not in the crypto business
joecool: covers the rust
mircea_popescu: that's why all the old chryslers and whatnot have them
mircea_popescu: joecool, finally someone explained bumper stickers to me.
mircea_popescu: it's almost like wanting to marry a virgin specifically.
decimation: this is true, and even the pros know it
joecool: mircea_popescu: stickers always make things work better
asciilifeform: if it's a crypto gizmo and has seal - which i didn't put there - i've no interest in it.
asciilifeform: 'doctor it hurts when i do that. -- don't do that.' ☟︎
asciilifeform: decimation: rng design that involves the purchase of an active volcano is probably expensive too.
mircea_popescu: oscialltors are iffy tho
decimation: was going to be 4 hours work max
decimation: Last I called, NIST wanted $5-10k for "labor costs" to measure the phase noise of a microwave oscillator
decimation: K-S tests etc
decimation: but but ascii they said it's good to 8 sigma!
asciilifeform: your simulated annealing turd won't converge, you'll sit & curse the gods
decimation: it's a good point. Part of the problem is that actual calibrated analog noise sources are expensive
mircea_popescu: benkay, "it's all hazy probability fields at this point" << so start before you fly over, get a nice scorpio, maybe it turns out a girl with big green eyes etc.
asciilifeform: even for simulation purposes (actually the original source of my interest in rng design, years ago) lfsr is crap. you get creeping periodicities.
decimation: well, to be fair I think the application is to generate noise for comms. simulation purposes, not crypto
asciilifeform: why? ask the builders, not me
asciilifeform: decimation: LFSRs suck. and virtually every academic treatise on rng design assumes a very impoverished physical entropy source.
joecool: asciilifeform: probably, I honestly never looked at that, will go read now
asciilifeform: am i the only one here who remembers how rsa sig algo works !?
decimation: You can just put the user 4-digit pin into a key derivation algorithm :)
decimation: ascii have you seen this paper http://www.ee.usyd.edu.au/people/philip.leong/UserFiles/File/papers/wallace_tvlsi05.pdf
asciilifeform: (e.g. the hardcoded master key that inevitably turns up in audits of various crapware)
asciilifeform: orthogonal to this is the other problem, that you (owner) have no way of verifying what it is the gizmo is capable of
asciilifeform: the very next time victim enters pin.
asciilifeform: if you plug dumbcard into a pwned box, it will sign whatever the enemy wants to sign.
joecool: asciilifeform: pretty sure in the case of the smartcard it needs to initialize the card to know that it is, all it sees is a reader otherwise
asciilifeform: fails the 'would you plug this in at dr. evil's house?' test.
asciilifeform: joecool: not only this, but laptop 'knows' that a crypto gizmo is connected.
joecool: the only assurance you have is a signature counter in the smartcard
joecool: asciilifeform: i don't generate keys on card for the rng issue, need to upload from laptop, but yeah sure no way to enter pin outside the laptop
decimation: I also wonder if the antiphase headphones are modulating my eardrums at frequencies beyond my perception
joecool: i'm a big fan of westone's products, i switched to them from shure awhile back
asciilifeform: bose is a terrific scam (what spends so much on glossy magazine ads, and isn't ?)
decimation: To be fair I haven't purchased the fancy "pilot quality" headphones made by bose etc.
joecool: switched to an amp and they sounded like a very different pair
joecool: can be solved with an amp, i didn't believe sensitive IEM's would be affected till i had a pair with a picky crossover
joecool: rolloff at lower freq is usually due to running inefficient low impedance headphones off a bad source
decimation: I found really great NASCAR earphones that have 30 dB attenuation down to low frequencies - I look like a tool on the airplane
asciilifeform: decimation: same. this is because they inevitably emit an audible hiss of their own.
