mircea_popescu: of course, he got half of the discussion of etymology of engineering from the older discussion ; it's true that in french it comes from ingenuity however in english it comes from engine. which was the fucking point, this slide.

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: what does mircea_popescu use currently?
Framedragger: i guess you meant conceptually dead, and with definite practically-dead event horizon in sight
mircea_popescu: Framedragger because who knows, but it is under 10%, a lesser opera by now.
mircea_popescu: both chrome and, insanely, ie, the ie above, ate it.
mircea_popescu: Framedragger nah, it's been going on for 2-3 years at the least.
Framedragger: so suddenly the numbers of wide populace matter? :)
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: it's not a strategy for anything than for the pernicious insanity of "marketing matters".

trinque: if we want to get out the real tin foil for a minute, somebody might suspect the "great powers" have been planning on how to restructure the middle east *together*

mircea_popescu: course btc.com is half that.

asciilifeform: re 'open sores', even a ~very~ small gadget, and in fact one that started life as a stand-alone library: mpi (bignum) piece of gpg 1.4, was quite astonishingly painful to properly saw off the kochball
asciilifeform: there were tentacles throughout.
asciilifeform: it was also a demo of the utter malignant idiocy of automake (zapped! and you won't miss it, thing builds on all major unixlikes with a single 'make')
mircea_popescu: may be worth your time to specificallyt document this
asciilifeform: killing automake cut the size of the thing literally in half.
mircea_popescu: for later, have a proper example of wehat these metaphors mean.
asciilifeform: i actually sat down to write a long and painfully pedantic piece about what i did, but gave up, let the diff speak for itself
mircea_popescu: i think that wasn't the right choice.
asciilifeform: it was literally a week+ of sawing off #includes, nixing #ifdef's, moving blocks of code from 1,001 places and deduplicating, etc.

asciilifeform: in other noose, asciilifeform recently bought a 'top of the line' civilian motherboard, and as soon as being lifted from the crate, it shed a few 0805 capacitors
asciilifeform: unleaded solder ftw.
mircea_popescu: in the same vein, i have now spent in excess of $300 buying no less than nine "pc sound systems" over the past 2 years. i have nfi why i decided to just buy one of the cheapo, two speaker things. and then replace it and so on.
asciilifeform: they burn out ?
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.
mircea_popescu: im guessing a capacitor went. this time.
asciilifeform: aaah those
mircea_popescu: another one, the transformer went, evidently, wire too thin and melted
mircea_popescu: each had a different story of sadness, and all together they could have made a small rocket. if only their materials weren't allocated by idiots, that is.
asciilifeform: i recall i threw one just like this out, and kept , to my grief, its transformer. which then nuked $1000+ worth of various iron i connected it to, because the voltage it put out was actually ~double what was on the sticker.
asciilifeform: (the speakers -- did not care.)
asciilifeform: even simple thing, that i would have bet money no one could fuck up -- fucked up. ~year ago i bought 'antistatic mat', conductive rubber thing with coiled cord that goes to ground pin of mains socket, etc. that cord is now frayed in 11 places.
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
asciilifeform: because the thing that was supposed to sit in the socket, would wiggle, like 'hotdog in hallway'
asciilifeform: had to bend it so it would sit even moderately still and make contact
asciilifeform: i must echo the words of mircea_popescu's electric heater article, and say, that such a thing could never appear by chance, someone busted his arse to design something so malignantly anti-functional .
asciilifeform: the other hypothesis that invites itself is the tlp/mp 'ceremonial object' one. the, e.g., static mat, was sold on a www with reviews, and not necessarily faux ones. many satisfied sheeples own various tools and NEVER USE, and they -- are quite happy!
asciilifeform: because 'mine is still in great shape after 5yrs' 'how many times you used it' 'umm... 1? 2?'
asciilifeform: 'all wire frays' 'really nao? i have wire here from 1940s that is frayed in 0 places'
asciilifeform: questionable metallurgy is another thing. not only pb-free solder, but, e.g., aluminum wire.
asciilifeform: much less ductile than copper, and it frays.

mircea_popescu: have you talked with your lathe about its feelings ?
asciilifeform: i've lost count of how many times i buy a not-the-cheapest $tool, and after 2-3 uses it crumbles into, literally, dust, and then buy 'nice' one, which half the time has been chinafied/plasticized already into very close resemblance to the el cheapo item, sometimes beyond any meaningful diff

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: 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
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
ben_vulpes: leastaways not in my head
trinque goes to find the "cleave the network fiddling and block verifying parts of trb" thread
davout: ben_vulpes: when aggregating the outputs, nuke those for which a spent out is found? it sounds pretty trivial to me, am i missing something obvious?
a111: Logged on 2016-12-20 19:40 mircea_popescu: at the very least block digestion and peering must be cleaved in trb
a111: Logged on 2016-11-02 15:33 asciilifeform: after slicing apart mempool-node from blockchain-node, building 'dioded node' becomes trivial exercise.
trinque: also that
ben_vulpes: davout: you know maybe i need another cup of coffee
davout: guess the "how do we then ban peers that send garbage" has been brought up wrt the network/data validation cleavage
asciilifeform: trinque: it isn't , currently, clear to me that you can make this cut cleanly without hard-breaking with the traditional protocol.
davout: ben_vulpes: what time is it in ben_vulpistan?
ben_vulpes: davout: "impossible without gossipd" according to asciilifeform
asciilifeform: (what does the thing that actually speaks with peers look like, in your view ? peers will ask for, and send, blocks AND tx, on same socket, as per current protocol.)
ben_vulpes: davout: dunno, "just biked into office after spending as much time with family as i wanted o'clock"?
ben_vulpes: ~noon
asciilifeform: ben_vulpes: feel free to suggest solution that does not 'require gossipd' but is also not perlistic ducttape.
asciilifeform: everyone will clap.
ben_vulpes: asciilifeform: just trying to get the guy up to speed
ben_vulpes: i generally assume "everyone will clap" but rarely have that for which
trinque: I was going to say the same, does require gossipd
trinque: "don't talk to idiots" is a far broader problem than bitcoin
asciilifeform: 'requires 80% of gossipd' would be a stronger statement, but then i'd have to explain which 80

asciilifeform: (as it presently does)
mircea_popescu: what is this "one binary", for srs.
asciilifeform: 1 process, in which all threads share (quite catastrophically, as readers of trb ml will know) the heap.
mircea_popescu: well shit, we specifically don't want this
mircea_popescu: so hence my answer!
mircea_popescu: http://btcbase.org/log/2017-01-03#1595700 << this has the cheap solution of "spent prevails" on the theory that it can't be the case an unspent input is ever found spent.

mircea_popescu: it ~may~ be the case that some arbitrary level of cleanliness requires an entirely new universe. this, however, can never inhibit the brushing of toilets.
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: no such third was contemplated ; when discussing a proposal you are stuck, willy nilly, first understanding it and then referring it
asciilifeform: mircea_popescu: draw the cut plox
mircea_popescu: you're not at liberty to discuss something else, in different terms.
asciilifeform: explicitly, where do you propose the cut
a111: Logged on 2016-12-20 19:42 mircea_popescu: nope. blockchain part will get to it when it gets to it, and tell you. until then, peer part builds queues.
asciilifeform: your 'b' : mempool+networking, 'a' -- blockchain ?
mircea_popescu: which mempool ? each b has one, as a queue.
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: 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.
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: to rephrase: the resulting vdiff would be quite far from minimal
lobbes: http://btcbase.org/log/2017-01-03#1595456 << "First, and obviously, since the majority of the students are going to get an A, he just has to do just as well/horrifically as the average student, and if they're all writing about slavery with the enthusiasm of a photocopier then if he wants an A he better buckle down and learn the truly useful skill of masking the words of a Wikipedia page.

asciilifeform: (gigantic deletes and inserts, rather than the actual 'we moved such-and-such lines to this-here place...')
mircea_popescu: asciilifeform this is a problem yeah. will however have to be bit, wtf else to do.
mircea_popescu: "never change anything" i guess.
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!
lobbes: That was a great read, thank you. Lined up exactly with my own anecdotal experiences. If I learned one thing in 'business school', it was how to properly bullshit. Only cost some 20k! Real learning didn't happen until after graduating (funnily enough, I also learned to drive -after- getting my license)
mircea_popescu: asciilifeform i dunno, one huge insert patch is still pretty dubious as far as paternity goes.
mircea_popescu: i suppose it IS easier to check though
asciilifeform: hence 'palliative'
asciilifeform: but a differ that ~understands moves~ would be quite spiffy.
asciilifeform: ditto deletes.
asciilifeform: !#s teco
mircea_popescu: myeah. and if unfixed this issue liable to recur.
mircea_popescu: v is really only as powerful as the underlying differ is.
davout: but if it really needs a magical difftron, can it still be said the operator can see everything with naked eye?
lobbes: Re: wikipedia. I remember early on in grade school I was actually taught that wikipedia was shit. By the time I entered college this tune had changed. Now it all makes sense
mircea_popescu: davout the gordian knot is how to make it both unmagical and self-summarizing.
mircea_popescu: this is obviously true ai problem.
asciilifeform: davout: that'd depend on 'how magical' , neh ?
davout: sure
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.)
mircea_popescu: i suspect graph theory may have a solution for us, but it is not clear to me how.
asciilifeform: this is why the original genesis was such a painful affair (and why it was and remains important to READ how i did it)

BingoBoingo: lobbes: You had wikipedia in Grade School! Poor Child!
asciilifeform: the entire point in using a differ in vtron at all (as opposed to signing ENTIRE body of work) is to make the work of the reader tractable.
asciilifeform: a patch that has any significant 'cut-and-pasteology' -- tends to make it intractable again.
asciilifeform: (if i cannot ~mechanically~ tell that the untouched parts are untouched -- they are, for all intents and purposes, touched)
mircea_popescu: still, due to the fact that v allows attribution, the change can be digested over time.
asciilifeform: theoretically.
asciilifeform: in actual practice, gigantic turds take eons to fit in head.
asciilifeform: as, e.g., trb itself.
asciilifeform: (it remains to be seen if the thing had ever, or will ever, fit entirely in any head)
mircea_popescu: still, the "frozen trb because networking" or "because badlt done block check" etc can't go on forever.
asciilifeform: though what i pictured is that trb can finally produce the motherfucking ~book~ and it will be possible to start rewrite...
mircea_popescu: and what i pictured were 72 cubits high, translucent, ageless, nonmenstruating and deliver pregnancy to term within the day.
lobbes: BingoBoingo: aha. Yeah, I guess more towards high school. Luckily I was just old enough to still have been taught how to research using actual b00ks and/or libraries.
asciilifeform: mircea_popescu: these: next!111
mircea_popescu: right-o.
asciilifeform: mircea_popescu: imho it is necessary to 'defile grandfather's pistol' in certain carefully-selected ways, but only if it can be done while making it clear that it was defiled in ~these but not other, unspoken~ ways

a111: Logged on 2017-01-03 21:29 asciilifeform: though what i pictured is that trb can finally produce the motherfucking ~book~ and it will be possible to start rewrite...
asciilifeform: davout: thing is, there is no such thing as this 'hot core'
asciilifeform: spittoon is in, imho, one strand.
asciilifeform: asciilifeform's (and later again jurov's) utter failure to unravel the heap, at least, suggests this.
asciilifeform: this was, if anyone recalls, the reason i asked for the functional flow graph
asciilifeform: to lean what ~actually depends~ on what.
asciilifeform: so that the places to make all plausible cuts become apparentl
asciilifeform: *apparent
asciilifeform: (unfortunately a flow graph where every motherfucking line intersects 55 other lines, is NOT good for anything)
davout: yet another obvious benefit of amputating the wallet, miner and everything that can pretty obviously done without
davout: but i also get the other point, a lot of that complexity becomes apparent once one actually goes ahead and pops the hood
asciilifeform: i historically refused to touch the miner, and will not encourage anyone to touch it, because neither i nor anyone i know is equipped to properly test the result.
asciilifeform: (a result where there is ~no~ miner available, i exclude from consideration because it pisses on the R in 'trb')
asciilifeform: wallet - sure.
asciilifeform: now you ~could~ make the -- imho very tenuous -- argument that mining logic is ~implicitly~ present in the block verification logic.
asciilifeform: but it is a stretch. and does not let you ignite a bitcoin overnight if transported to alpha centauri (or, more likely, earth-with-broken-mainnet)
asciilifeform: trb miner is mircea_popescu's 'fleet in being'
asciilifeform: gotta be ready to roll on five minutes' notice if the old miners ALL go home SIMULTANEOUSLY.
asciilifeform: incidentally, ben_vulpes -- what height are your 'solipsist nodes' up to nao?
ben_vulpes: asciilifeform: i've been working on phf's recommendations of late
ben_vulpes: so -- zero
ben_vulpes: haven't made checkpoints configurable, so solipsist nodes won't even mine
ben_vulpes: unless i misunderstand, the project is truly blocked on making checkpoints configurable.
davout: asciilifeform: i don't thing the argument that the block validation logic can be found in the block validation logic is tenuous
davout: make the miner a separate bin
ben_vulpes: (fwiw i'm down to the last ghostly suggestion, which was to read in the hash as a bignum)
asciilifeform: davout: aha, separate bin. but not 'today NO miner and MAYBE SOMEDAY a new miner'
asciilifeform: no transformation of mud-todays into jam-tomorrows plox.
asciilifeform: ben_vulpes: what means 'as a bignum' ?
asciilifeform: i.e. as an object you can divide by 33 ?
davout: asciilifeform: i think it would be hard to make the argument that a separate binary sitting aside the node could hurt in any way
ben_vulpes: asciilifeform: i misspeak, 'as an integer'
asciilifeform: davout: could, theoretically, hurt, if it requires adding 100,000 lines of i/o glue logic
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
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?
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: 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"
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)
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: 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.)

a111: Logged on 2017-01-03 22:24 asciilifeform: they will require a -- quite complicated -- entirely new protocol
mircea_popescu: the whole point is for them to NOT speak to one another.
asciilifeform: mircea_popescu: how does txtron accept/reject without talking to blockchaintron?
asciilifeform: what am i missing
mircea_popescu: puts into queue. accepts nothing, rejects nothing.
asciilifeform: who eats the queue then ?
asciilifeform: so they talk! via the queue
asciilifeform: (trb.b, presumably, polls..?)
mircea_popescu: no. one just reads, the other just writes, at all points where they interact. no talking is contemplated, and if this is "a protocol" then it's already given.
asciilifeform: what happens when evilpeer dumps a TB of liquishit into the queue?
mircea_popescu: do you read the spec or just sit there and dream a little dream ?
a111: Logged on 2017-01-03 20:48 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: including that part ?
asciilifeform: aha, incl that part.
mircea_popescu: so then what happens ?
asciilifeform: in the tx case, anybody can overwrite legit tx in your buffer by dumping liquishit in.
mircea_popescu: there is no tx. you do not read. what is N.B ?
asciilifeform: candidate-block receiver, neh?
mircea_popescu: so then.
asciilifeform: in the case of candidate-block and candidate-mempooltx queue receiver (from outside the walls), mircea_popescu proposes to throw out even the weak logic for banning obvious crapola that we have today in trb?
asciilifeform: (banning would, as far as i can tell, require 2way comms b/w the modules)
asciilifeform: and whatdoyoumean 'no tx', is the thing contemplated a wholly mempool-less node ?
asciilifeform goes to reread mircea_popescu's scheme
mircea_popescu: i don't think today's logic does anything ; and i don't expect carrying it forward is useful. spec does include room for trb.n to do some banning, including on the basis of passively exfiltrated data from trb.b. that a protocol for this purpose may later develop i don't dispute, but it's not included both because it's not needed and because it can't become a "dependency". it's not.
mircea_popescu: and no, not wholly mempool less. there is m.t. what it contains - we care not. when problems will arise, they will be solved without impacting on the core scheme.
mircea_popescu: that being the fundamental point of separation in the first place.
mircea_popescu: (the correct solving scheme is still as i said back when we were discussing mempools, to keep track of peers (yes, by ips) and score them by the fees they bring your mempool. with this change -- that is even implementable.)
asciilifeform: while i like the 'diode' aspect of this scheme, i will say that my public nodes would fall down in about three seconds, and permanently, if the primitive autobanhammer of gaviniferously-symptomatic peers were to be switched off.
asciilifeform: (confirmed, experimentally.)
asciilifeform: perhaps if nothing could possibly land in the queues faster than it can be eaten, this would not be so.
mircea_popescu: you don't have to switch it off ; carry it over.
mircea_popescu: i have no idea how you maintain your mempool atm ; or if it is what you're talking about even, is it ?
asciilifeform: stock trb mempool
mircea_popescu: so then use that. as the spec says, m.t specifically left unspecified.
mircea_popescu: this is what "trb.n inherits network code" means. let it inherit.
asciilifeform: well the old code has ban(...) which instructs 'this datum was a malicious turd and i dun want no moar from that ip'
mircea_popescu: and reads the blockchain to do that ?
asciilifeform: in the case of verifying a block -- it does
mircea_popescu: we were discussing txn and mempool.
asciilifeform: in those, you also need blockchain
mircea_popescu: then no wonder your node falls over.
asciilifeform: (a tx can have valid form in all sense other than being a doublespend, mircea_popescu knows this)
mircea_popescu: i do, but it is also insanity.
mircea_popescu: you cvan not engage in an open ended "i will for all comers do the work of checking one cent txn against a 10 dollar blockchain".
asciilifeform: it is physical reality, and ergo by definition no moar 'insane' than gravity. unless mircea_popescu offers a breakthrough where we can test doublespendity without keeping blockchain around at all
mircea_popescu: to doublespend you have to MINE it. to accept something in mempool, does not mean it has become accepted in blockchain.
mircea_popescu: something like "one txn accepted in mempool per hour per peer" is reasonable.
mircea_popescu: how MUCH verification work i wish to do for the world - is my choice, not the world's.
asciilifeform: mircea_popescu: here i gotta agree, the 'allcomers can get their tx candidates evaluated' is doomed
asciilifeform: just like i can't go and offer a candidate tx to swift because i feel like it
mircea_popescu: worked while it worked but on the long term "collegiallity" of this elk is unsustainable.
asciilifeform is a bit more 'doomer' than mircea_popescu on this subj, and does not see a future for 'anyone can send packet to anyone' net in ~general~
mircea_popescu: yes but there's at least a decade between these.
asciilifeform: 1 tx / hr / peer will make for one hell of a turtle relay
mircea_popescu: tough titties, get in people's wots/gossipds.
mircea_popescu: this is a fine avenue of rebalancing the miner/node nonsense.
mircea_popescu: (yes, yes, "prb nodes will outcompete". sure. and reddit/wikipedia/etc outcompete us, totally.)
asciilifeform: seems to me like it might unduly empower miners.
mircea_popescu: how do you reason ?
asciilifeform: if being 1 hop closer to a miner now means an hour less avg. delay.
asciilifeform: instead of a few min.
mircea_popescu: davout your four main pieces are a b and c ?
mircea_popescu: asciilifeform nobody forces you to keep the throttle in place for your friends.
asciilifeform: how does your box know who are 'friends'
mircea_popescu: so in my thinking it incentivizes proper behaviour.
mircea_popescu: by ip. yes yes, i know i know.
asciilifeform: you gotta have the crypto auth.
asciilifeform: and RST-idiocy-proof pipe.
asciilifeform: aite, we had thread, i won't repeat
mircea_popescu: these are good-to-have, not dependencies. let the lizzard queen fuck with ips a while first.

mod6: yeah, actually, now that I think about it, i was told that in this particular case I was talking about, the guy didn't even put in regular unleaded (87 octane), he put in like 110 octane racing fuel.
mod6: lol
mod6: i guess this took place at a refueling stop in the middle of the night.
