a111: Logged on 2017-01-02 21:40 mircea_popescu: if the same archbishop inquires as to why i poured cement the way i did i can answer without ado.
asciilifeform: so mircea_popescu with his cement mixer is just as 'dirty empiricist' as d00d who writes 'while (1) {.......}' without having written a c compiler and ability to explain what {} 'do' rigorously
trinque: misses the point entirely; the question is how to teach the thing
trinque: and when someone can be said to understand it
asciilifeform: teach c machine as sane people were taught: 'here's some c, here's what compiler emitted , in asm, now say why'
asciilifeform: and student knows asm because started there
trinque: one moment "nobody can fit c machine in head" and the next "anyone can c puny human!1!1!!"
trinque: lol
trinque: yes, one can memorize a mapping between some phenomena and their effects, and this does not amount to "understands computers"
trinque: I thought asciilifeform had a www on this
trinque: and incidentally, didn't jurov do something with eulora and lisp/scheme ?
asciilifeform: trinque: it is why you make the student write, eventually, the compiler
trinque: oh sure, no argument here. but then go and rewrite a compatible gcc
asciilifeform: trinque: iirc he stuffed ecl in there
trinque: ah

Framedragger: certainly nothing of huge import. some of those are definitely a bit snakeoil'y, but not completely useless. i don't know how much you care about e.g. browser fingerprinting. right now html5 canvas leaks badly, i.e. "The adversary simply renders WebGL, font, and named color data to a Canvas element, extracts the image buffer, and computes a hash of that image data. Subtle differences in the video card, font packs, and even font and graph
Framedragger: simple, high-entropy fingerprint of a computer. In fact, the hash of the rendered image can be used almost identically to a tracking cookie by the web server."
Framedragger: so turn off such on-by-default leakage (and other leakages for fingerprinting), etc.
mircea_popescu: Framedragger you are aware firefox is dead for all practical purposes, yes ? in fact i don't know any browser that lost market share at its speed, except of course netscape back in the day.
Framedragger: because of the recent whatitwas?
mircea_popescu: which is in itself a very amusing commentary on the toils and travails of the jwz gang. they... rescued netscape. and it did... netscape.

Framedragger: but i agree that things don't look too good.
Framedragger: (fwiw sandboxing efforts look nice and more technically involved; question is how easy it'd be to apply work done there to other browsers and so on; if not, meh) ☟︎
mircea_popescu: for a browser ? come on. it's not good. the only thing it had going for it were a bunch of retards using it. now it doesn't even have that.
Framedragger: yeah, gossipd client != browser. market share matters hm.
mircea_popescu: i use lynx and curl. ☟︎
Framedragger: that's cool.
Framedragger: (i at least check that my webpages look good on lynx/elinks)
mircea_popescu: i dunno how cool it is, but let me tell you it is very productive
Framedragger: i suppose you also avoid the 'why does a multibillion clock machine lag on key press omfg' fail as icing on the cake.
mircea_popescu: how the fuck would it lag, really now.
Framedragger: this one time, i was scriptifying cheap flight booking. was amazed how less-laggy the simulated/automated 'browsing experience' (website didn't like bots, needed to convince it by running part of actual browser) was (cf. manual clicking on airline's website). got depressed
Framedragger: sorry state of affairs.
mircea_popescu: the moment they start with "not like bots" you know they're imbeciles.
Framedragger: some airlines (such as ryanair) try to stuff the user with tons of shitty offers before reservation confirmation page. horribru UX. such m0netizzation $trategy. imbeciles indeed :/

mircea_popescu: the last pair died in the lulziest of ways : it's usb powered, and it will short the usb when the sound is loud enough, lose power, then come back a half second later.

asciilifeform: each hanging by hair's breadth of wire now.
mircea_popescu: and thereby working more as antenna
asciilifeform: was ok antenna even when new

davout: and if you don't, well, you're back at "monitor subset of all addresses" which immediately reduces to "wallet"

ben_vulpes: davout: have you considered hammering a spigot in for "gimme utxo's relevant to this address"?
mod6: that's just like the listunspent thing that i backported.
davout: ben_vulpes: i'm listing it as an option
davout: downside of it is "node has to know which addresses to monitor, still has to keep clunk 'rescan' logic as well"

davout: ben_vulpes: to take arbitrary addresses it needs an UTXOs indexed by addresses, which isn't cheap
asciilifeform: trinque: what, in your analysis, is the set of orthogonal pieces 'wallet' breaks into ?
ben_vulpes: davout: or to lean on the clunk, right?
davout: trinque: yeah, that's the kind of design i'd like to end up with
davout: ben_vulpes: i failed to parse
ben_vulpes: instead of maintaining whole 'utxo pool', rescan for specific addresses on demand, shit utxos for that addr onto disk.
trinque: asciilifeform: utxo index for arbitrary selected addresses (emphatically not for all addresses including one user just pulled from his ass), tx maker, tx signer, tx sender
trinque: my wanting to track an address balance may have nothing at all to do with *me* spending to/from that address
davout: ben_vulpes: sounds slow, although i confess i haven't actually experimented
asciilifeform: trinque: looks reasonable
asciilifeform: how does 'tx sender' work ?
davout: trinque asciilifeform tx-sender must be built-in node
trinque: sure
ben_vulpes: davout: a full rescan of the blockchain takes ~12 hours on mod6's machine
ben_vulpes: mod6: or was it shorter?
mod6: it wasn't that long
asciilifeform: the sad part is that this is 'embarrassingly parallel'
trinque: davout: I agree with "RI must bitcoinate *completely*"
davout: ben_vulpes mod6 could probably be heavily parallelized too
mod6: iirc it was somewhere between 3-6 hours.
ben_vulpes: davout: aye
davout: trinque: but "must RI be a single binary?" ☟︎
trinque: asciilifeform: tx sender is just a "sendrawtxn" that eats the data from user. maybe he made the txn with other RPC calls, maybe got from elsewhere
ben_vulpes: davout: what if one thread finds a tx spent that another thread finds the unspent for
asciilifeform: ^
asciilifeform: i get it, the 'decouple everything', 'unix philosophy!!!' thing is appealing. but it runs into practical limits.
davout: ben_vulpes: if i namedrop 'map-reduce' does that appease you?
asciilifeform: we recently had a thread, where i described how parts of phuctor are quite slow precisely because of such decoupling.
davout: i haven't thought about the rescanning approach much
ben_vulpes: no
trinque: davout: hard to say with current rats nest if things could be that cleanly separated ~starting from trb~
ben_vulpes: because "map-reduce" does not reduce to "here's how i'm going to solve specifically the case where thread n finds an unspent out and thread n+1 finds its spent and in the reducing phase i collate everything proper-like" ☟︎
davout: asciilifeform: nobody said it was cheap, maybe we end up finding out it's not really worth it

asciilifeform: mircea_popescu: the tcp stack per se does not offer any means whereby two proggies speak simultaneously through 1 socket
mircea_popescu: this was not an input in teh scheme.
asciilifeform: so you end up needing a third. (supposing that you are trying to speak the old protocol, with heathens!)
asciilifeform: because if not, then naturally -- not.
mircea_popescu: you do not. a speaks through b and through b only.
asciilifeform: who's b ?
mircea_popescu: b handles the networking ; a handles the blockchain.
asciilifeform: so b there is the 'third' contemplated earlier.
asciilifeform: (really, a 'c', 'a' speaks blockchain and 'b' speaks mempool)

mircea_popescu: each b, a have one, i mean.
asciilifeform: aite, this is the interpose thing
asciilifeform: (imho good idea)
mircea_popescu: "i have heard this transaction" is of interest to b ; not of a. "this is a transaction from a block" is of interest to a.
mircea_popescu: yes, they're both "transactions" in the terms of the eventual datastruct they'll occupy. they aren't for that reason the same thing.
mircea_popescu: but anyway, this is all well known matter.
asciilifeform: it might be worth mircea_popescu's time to write a detailed sketch of this item.
asciilifeform: (the 'sanity proxy', if you will, for trb)
mircea_popescu: hm.
mircea_popescu: asciilifeform :
mircea_popescu: TRB to be split into two parts : TRB.B and TRB.N. Queues B.B B.T N.B to be created. TRB.N inherits the code to connect to peers. TRB.N reads blocks from peers, and puts them in N.B. TRB.N reads txn from peers and puts them in M.T. TRB.N does nothing else (with the possible exception of rate limiting for peers). TRB.B reads N.B and verifies the blocks. if the block is verified it is added to B.B and its component txn to B.T ;
mircea_popescu: otherwise it is discarded. B.T may be pruned (according to arbitrary address list, for instance). Rate limiting in TRB.N may be constructed to observe N.B items that fail to propagate to B.B and ban the originating peers. ☟︎
mircea_popescu: all three queues to be implemented as ring buffers of user specified size. ☟︎
mircea_popescu: M.T deliberately left unspecified, it is the equivalent of today's "mempool". perhaps should also be a ring buffer like the other 3.
mircea_popescu: in any case : TRB.N needs write access to N.B and M.T and read access to B.B ; TRB.B needs read access to N.B and write access to B.B and B.T. it may be a good idea to also give TRB.N read access to B.T but this should be operator-knob
asciilifeform: what does B.T do ?
mircea_popescu: that's ~the wallet.
asciilifeform: N.B ?
mircea_popescu: "watched addresses", or something of this kind.
mircea_popescu: "blocks that have been recevied via the network"
mircea_popescu: this scheme among other things cheaply allows the "add arbitrary new address to wallet", just have utility that (separately) processes B.B and produces new set of B.T. ☟︎
mircea_popescu: but it is not required for B.T to be used only in this way or for this purpose. in principle there could be a whole pile of these, readily extended into whatever operator wants to do.
mircea_popescu: "this is my B.T1 of all txn with no fee, this is my B.T2 of all the payments to my X, this is my B.T3 of all txn over 5kb relayed by ip X"etc.
mircea_popescu: it seems certain B.B belongs on disk. it seems likely B.T also belongs on disk. it seems certain M.T belongs in memory. it seems likely N.B also belongs in memory.
mircea_popescu: in particular N.B should be "older overwrites newer" style ring buffer. of particular concern are situations where the buffer is set shorter than the longest reorg, in which case the node will wedge. TRB.N not accepting blocks with index lower than highest of B.B is for sure not feasible. "how many behind" should be an operator knob. ☟︎
mircea_popescu: (this knob is then in practice equivalent to the "checkpoints" discussed previously)
davout is getting lost in the variable names
mod6: i drew myself a diagram, helps.
mircea_popescu: N indicates networking, B indicates "blockhain", or homebase or whatever.
davout: hrm, i'll have to re-read ☟︎
mircea_popescu: anyway, the great gain is that no two elements need/have write access to the same thing by this scheme. in point of fact one way to look at current trb/prb is to say that they have "write locks" on all the fucking time and deadlock.
mod6: indeed, synchronized code everywhere.
asciilifeform: mircea_popescu: i can think of one (nonfatal, but quite unpleasant) headache: without a less-idiotic replacement for gnudiff, the resulting cut-trb becomes very difficult to pedigree to trad-trb . sorta like the problem with the tabs/spaces cleanup proposed by mircea_popescu last year

asciilifeform: i can think of a few palliative pills for it, in particular to structure the deletions and insertions in separate vpatches
asciilifeform: but it does not ~solve~ problem, only makes it manageable.
mircea_popescu: lobbes this incidentally explaisn why wikipedia is such shit - it's ~only function is a sort of open-sourced cliffnotes, and people would much prefer it to be bland and stupidly written so the teacher in class doesn't feel too inclined to think the kids' lifted material isn't his. after all he added all the flavour words in there!

mircea_popescu: asciilifeform i dunno, one huge insert patch is still pretty dubious as far as paternity goes.
asciilifeform: yeah
mircea_popescu: i suppose it IS easier to check though

asciilifeform: mircea_popescu: i'm not entirely certain that the problem is solvable (it IS possible to define a richer diff language that permits block moves, but this also permits inscrutable-to-naked-eye patches to exist.)

davout: but i also get the other point, a lot of that complexity becomes apparent once one actually goes ahead and pops the hood

davout: the miner does require the transactions being mined to be valid, so there's that
asciilifeform: let's take the cuts as specified by mircea_popescu earlier.
asciilifeform: they will require a -- quite complicated -- entirely new protocol ☟︎
asciilifeform: for the components to speak to one another.
davout: we might en up with a libbitcoinconsensus.a
ben_vulpes: triggered
davout: png
davout: trollface.png
davout: either way, imma head to bed, interdasted in comments re mah wallet cut piece
asciilifeform: davout, ben_vulpes , et al : it is also tricky to properly rule out the situation where split-trb node behaves like a 'split-brain patient', and external observer gets contradictory answers from it to some possible question
asciilifeform: (this is a certainty if the various components do not AT ALL TIMES agree)
davout: pilot handbook 101: "if after landing you need to apply full throttle to get back to your parking spot, you probably forgot to lower the gear"
asciilifeform: aahahahaha
asciilifeform: davout: similar book i recently read -- claimed that 'gear retract on parking lot' accidents are still a regular thing
asciilifeform: i gotta wonder why
asciilifeform: gear button is right next to starter button, or wat.
davout: yeah, i've heard some things like that too
davout: in these case it appears the cause is often confusion with the flaps lever
davout: *cases
asciilifeform: lulzy
davout: after you land you retract flaps
davout: but obviously retracting gear isn't a good idea
asciilifeform: i'd naively think that this would've been resolved in 1930s, if not earlier, just make the levers vastly different (shapes, or lengths, and feel, etc) ☟︎
davout: i have nfi why some airplanes allow this
asciilifeform: davout: didja ever weigh in on the rudder thread ?
davout: asciilifeform: they *are* very different
ben_vulpes: fuck levers, pressure on the wheels should engage hard interlock
asciilifeform: (why do we still find pedals on ~all machines)
davout: asciilifeform: no?
asciilifeform: davout: http://btcbase.org/log/2016-11-30#1574899 << thread ☝︎
a111: Logged on 2016-11-30 21:04 asciilifeform: i have here a b00k on piloting circa 1940, and already then author insists that rudder pedals are obsolete and have killed a thousand men
davout: maybe i'll understand the answer to this mystery when i become retractable gear certified!
davout: small thread is small
asciilifeform: ben_vulpes: my current (wholly nonexpert) understanding is that airplane DELIBERATELY omits 'hard interlocks' wherever possible, on the principle that not-being-able-to-X-when-you-must is worse than can-X-when-you-mustn't ☟︎
davout: well, you need rudder, how else are you going to, you know, pilot?
asciilifeform: davout: e.g., 'ercoupe', had rudder, but linked to ailerons
asciilifeform: so 0 pedals.
ben_vulpes: i have only recently developed an interest in ice flugen mobiles
asciilifeform: ben_vulpes had a 'trains' boyhood didn't he.
asciilifeform: in 19th c!
trinque: anecdotally I seem to recall my dad talking about using rudder in crosswinds on large aircraft
trinque: ianap
davout: trinque: yeah, i have nfi how i'd land anything in a xwind without rudder
ben_vulpes: asciilifeform: sailboats, motorbots, cars, bicycles mostly
trinque: right, not as if you can roll the aircraft when you're about to touch ground (intentionally!)
davout: asciilifeform: i'll research this ercoupe thing, seems interdasting
ben_vulpes: horses and women as opportunity presented
davout: trinque: actually you *are* supposed to
asciilifeform: davout: it was a (long-extinct) machine from the age of 'everybody will have an airplane'
asciilifeform: davout: the place that made'em is not far from where i live, it was slowly demolished over decades
trinque: davout: in a not wings horizontally level manner?
davout: trinque: no
davout: when landing in a crosswind you basically apply rudder during the approach so that your airplane flies towards the runway, but the nose pointing to the side
davout: 'crab-like'
trinque: yeh, what I was fumbling for
ben_vulpes: note! this does not mean the wings are not horizontal
trinque: isn't that yaw?
davout: and when you are about to touchdown, you apply rudder to align the nose with the runway
davout: but that causes the plane to drift
davout: sideways
davout: you apply roll to counter the drift
trinque: yeah I thought that was called yaw
trinque: it is
asciilifeform: davout: are there any situations other than crosswind landings/takeoffs where you need yaw-without-roll ?
davout: if the wind comes from the right you'll end up landing with right wheel first, then left wheel, then nose wheel
trinque: oic
asciilifeform: (and in fact, do those entirely ~demand~ yaw-without-roll?)
davout: asciilifeform: yeah
davout: motor effects
davout: lemme check out how that's referred to in engrish
asciilifeform: davout: i thought motor effect could only affect roll
asciilifeform: (gyroscopic moment of the motor, but also differently-impacting stream from propeller on one wing vs other)
trinque: easiest example that comes to mind would be losing an engine on a multi-engine plane
davout: here ya go
davout: http://wiki.flightgear.org/Understanding_Propeller_Torque_and_P-Factor#Propeller_torque_effect
davout: asciilifeform: propeller torque is one thing
davout: gyroscopic precession of the propeller when changing directions is yet another thing
asciilifeform satisfied! will buy machine with rudder!
davout: also trinque is right, when losing an engine on a multi-engine you need to apply rudder to compensate for the thrust differential
ben_vulpes: yeah see when they start talking like this my flugenboner starts to droop
asciilifeform: ben_vulpes: wai's that
asciilifeform: most folxs' -- hardens
davout: which is also why there's yet another minimum speed for a multi engine running on a single engine
ben_vulpes: trained response to risky dynamics problems
davout: below which the rudder loses sufficient authority to compensate for the asymmetric thrust
davout: ben_vulpes: piloting when you're actually in the plane is an entirely different thing
ben_vulpes: asciilifeform: i suspect that if i start to explore this risk manifold i will have trouble not ratcheting the risk back
davout: basically "watch your airspeed, watch the fucking airspeed"
davout: also "the ball goddammit"
ben_vulpes: see http://www.liveleak.com/view?i=960_1477239016
asciilifeform: davout: different thing from what? from piloting on grid paper and with pen? i'd imagine so!
davout: asciilifeform: point is piloting a small plane there's just a few things to pay attention to constantly ☟︎
asciilifeform: ben_vulpes: lulzy contrast of the solid 'hp oscilloscope' goodness of the console buttons, with the crapple turd
ben_vulpes: amusing on so very many levels
ben_vulpes: asciilifeform: it would be utterly nutso to consider an ode/fluids sim as a hashing function, right?
asciilifeform: almost the very definition of terrible hashing function
asciilifeform: because the transition between 'irreducibly complex' and 'braindamagedly simple' phase space is unknown.
ben_vulpes: very similar inputs could, even over long runs, result in very similar outputs
asciilifeform: in a hash for just about any application you want to always live in the former and never, ever in the latter.
ben_vulpes: elaborate?
ben_vulpes: or point me at something to read?
asciilifeform: ben_vulpes: consider the things you actually want from a cryptographic hash
asciilifeform: just take a piece of paper, and list'em
asciilifeform: then list things you do ~not~ want
asciilifeform: and if you want reading material, reread the thread where mircea_popescu suggested crypto using transcendental constants etc
asciilifeform: (tldr -- a digital approximation of a complex process is 1) not ~the process itself~, noshit.jpg 2) not necessarily all that complex, in the chaos/avalanche sense, or in any way cryptologically hard)
ben_vulpes: mhm
asciilifeform: ben_vulpes: to take toy example: 'game of life' playing field state, with initial state S and move count M, naively might seem like good crypto
asciilifeform: but if you actually try this, you will learn that it is not.
asciilifeform: because 'life' automaton tends to settle into quiescent states (bunch of small oscillating 'critters', no real turmoil) ☟︎
ben_vulpes: myup.
asciilifeform: there is ~0 actual relationship between 'confusing to the naked eye' and 'crypto-hard' ☟︎
ben_vulpes: b-but turbulence!
asciilifeform: most schemes naively stemming from such confusion end up equivalent to electric version of invisible ink.
asciilifeform: ben_vulpes: if you know how to get effect entirely analogous to gas turbulence in a purely electric machine, there are many folks who will clap, do say.
ben_vulpes: i am no karman reincarnate with god's knowledge
asciilifeform: and if you can achieve it in a ~discrete~ system, you can get wolfram to drink himself to death, by properly demonstrating 'cellular physics' (tm) (r) where he failed. ☟︎
asciilifeform: all by itself it'd be a worthwhile thing, if only for this.
asciilifeform: to go back to hashes, and if you for some reason eschew 'when hiring fortune-teller, hire the cheapest', ☟︎
asciilifeform: i know of 0 uses for a 'hash' where the same ~input~ is not guaranteed to produce ~same output~
asciilifeform: but i could think of one definitive improvement over traditional hashes: non-algebraic (see recent 'rsa padding' thread) tranform
asciilifeform: *transform
asciilifeform: essentially, anything where you cannot, in any practical computer, express the hash's reversal as an n-sat problem
asciilifeform: all well-known hash algos, afaik, lack this property.
asciilifeform: they are arithmetical, because the designers insisted that the hash be computable in fixed number of cpu cycles.
asciilifeform: this is great from many pov but imposes own cost.
ben_vulpes: why is 'fixed number of cpu cycles' a great thing?
asciilifeform: because it is bounded
ben_vulpes: wyrdmantis: again with the laptop messages
asciilifeform: (and tends to be small)
asciilifeform: ben_vulpes: a non-algebraic ('programmatic') hash algo opens the possibility of crafted cpu-ddos
asciilifeform: esp. if the actual computation is unbounded
asciilifeform: (recall one of the nails in the ethertardium coffin)
jurov: http://btcbase.org/log/2017-01-03#1595849 iirc the issue is pervasive use of std::map, which fucks with the heap like horny pig ☝︎
a111: Logged on 2017-01-03 22:06 asciilifeform: asciilifeform's (and later again jurov's) utter failure to unravel the heap, at least, suggests this.
asciilifeform: aha
asciilifeform: and not only of std::map in the abstract, but of the same set of maps everywhere in trb, simultaneously, and at the same time with the pestilential global locks
asciilifeform: and there are no provisions for safely ~removing a tx~ from mempool, ever, at all
asciilifeform: (every tx in memory relies on its inputs being present , and at all times becomes a threat to crash the process if one should turn out not to be there. ~all pointers potentially dangle . thing is as rotten as could be imagined.)
