asciilifeform tore this out of a much larger proggy, and its fitness for any practical use is quite questionable, but ought to get the point across

asciilifeform: ben_vulpes: you probably don't need a similarity matrix other than the unit matrix for text diffs, now that i think about it.

asciilifeform: so you will have simpler proggy.

asciilifeform: (you could try an' do something clever with matrix with deprioritized whitespace, and the like)

asciilifeform: nah

asciilifeform: just matrix with different nums in it.

asciilifeform: but really you just want to rip out sim-score that's in there and put in one that's a straight =)

asciilifeform: i just described how to toss it out

asciilifeform: (defun sim-score (a b) (= a b)) ought to work.

asciilifeform: then lose everything from start of the paste to ;;init.

asciilifeform: well, through (load-sim....)

asciilifeform: anyway algo should be clear to ben_vulpes .

asciilifeform: ben_vulpes: not a formal one, afaik

asciilifeform: ideally it'd be 'like classic unix diff but less retarded re, e.g., moves'

asciilifeform: adlai: imho integration by parts was more interesting than nw

asciilifeform did both homeworks

asciilifeform: http://www.avatar.se/molbioinfo2001/dynprog/dynamic.html

asciilifeform: ^ nw is very often homework in algorithms class

asciilifeform: because it is example of 'dynamic algo'

asciilifeform: aha

asciilifeform: aha

asciilifeform: aka memoization

asciilifeform: adlai: waiwat

asciilifeform: there's a sequence-alignment altcoin..?

asciilifeform: ah lolsnoar

asciilifeform: i read the original turd, it was ill-specified

asciilifeform: adlai: even being a connoisseur and collector of crackpotteries , it was not much to work with.

asciilifeform: ben_vulpes: lol

asciilifeform: ben_vulpes: i'll suggest a 'p-tronic' format for diffs. N\........ specifies N retained-of-a octets (e.g., 5\abcde ) ☟︎☟︎

asciilifeform: this is to abolish the line-based idiocy of unix diff. ☟︎

asciilifeform: lines are crud because they make newline symbol 'magical'

asciilifeform: and result , potentially, in megatonne of needless repetition.

asciilifeform: (imagine diffing a file containing zero newlines)

asciilifeform: ~you~ don't need to count'em by hand.

asciilifeform: let's make example...

asciilifeform: take sentence 'a': 'i'm not fucking learning an aminoacid matrix to be able to use diff i tell you that'

asciilifeform: take sentence 'b': 'i'm quite certainly not fucking learning an aminoacid matrix to be able to use diff i tell you that'

asciilifeform: so, one possible diff might be : \4\i'm \+15\quite certainly \80\not fucking learning an aminoacid matrix to be able to use diff i tell you that ☟︎☟︎

asciilifeform: go and diff, e.g., some perl code, and see if you still agree.

asciilifeform: when 1 'line noise' character, somewhere in a 140-char line, changes.

asciilifeform: and it's a 1 to an I etc.

asciilifeform: that's not a general-purpose diff nao, is it.

asciilifeform: diff gotta eat any 7bit-clean rubbish.

asciilifeform: incl. heathenries.

asciilifeform: i dare say that a colourized, phf-style viewer can make the suggested char-differ quite readable in comparison with ye olde unixdiff.

asciilifeform: worth a try, costs 0.

asciilifeform: esp. if ben_vulpes makes a proper aligner.

asciilifeform: (he'd have to for either kind)

asciilifeform: mircea_popescu: really idea is stolen from teco

asciilifeform has not so many entirely new idea.

asciilifeform: incidentally iirc phf's vtron internally converts diffs to something quite like this form

asciilifeform: (for the colour viewer thing)

asciilifeform: the one thing i consider a major win here, compactness aside, is the freeness-from-inbandmagic.

asciilifeform: no, see,

asciilifeform: the ....... in \N\....... can be ANY octets.

asciilifeform: incl. \ , 991\\\\\235\9824 , etc.

asciilifeform: because the machine knows how may to skip.

asciilifeform: *many

asciilifeform: the count.

asciilifeform: or you meant of \4\

asciilifeform: which can be a, e.g., \4\

asciilifeform: (retain)

asciilifeform: or a \+4\ (add four) or \-4\ (lose next four)

asciilifeform: \\4 does zip.

asciilifeform: or rather, it is a literal string, and ought to be subsumed in one of the above forms.

asciilifeform: any characters found not in one of the 3 above states, make the entire diff nonwellformed.

asciilifeform: (throw it out)

asciilifeform: but any octet is legal inside a proper counterstate.

asciilifeform: mircea_popescu: like pkzip, or just about any format since 1962

asciilifeform: and sure as fuck you can tell

asciilifeform: didn't i post , right here, a well-formed-to-naked-eye-but-not-to-vtron vdiff ?

asciilifeform: during FUCKGOATS release.

asciilifeform: http://btcbase.org/log/2016-12-11#1581252 ☝︎

asciilifeform: it wasn't a blob.

asciilifeform: it was valid ascii

asciilifeform: separate issue

asciilifeform: incidentally you will blow up on the +++ mine if you try and diff a vdiff. ☟︎☟︎

asciilifeform: same mine.

asciilifeform: (it so happens that the original happened on a uuencoded shit, tru)

asciilifeform: why have any more mutilation of the text than necessary ?

asciilifeform: and why magic newlines.

asciilifeform: why not 1 magical char instead of entire fucking magic words like +++.

asciilifeform: it ain't a blob

asciilifeform: 3 state.

asciilifeform: has mircea_popescu ever tried to implement traditional unix diff ?

asciilifeform: and see how many states.

asciilifeform: it only looks easy because you are familiar with it.

asciilifeform: 'muscle memory, thinking man's worst enemy', who said.

asciilifeform: (iirc it was mircea_popescu !)

asciilifeform: iwhat..?

asciilifeform: here's gedankenexperiment. take file of aaaaaaaaaaa.....aaaa (1MB worth.) add, 512kB in, a 'b'. how long is your unix diff ?

asciilifeform: can you read it ?

asciilifeform: my diff is about a dozen chars.

asciilifeform: 'patches must be superbly-commented works of knuthiana' is promisetronic.

asciilifeform: (i don't even disagree, that they ought to be.)

asciilifeform: it was a somewhat pathological example. but i will point out that in this system , mircea_popescu's tab-corrector patch would be 100% human-readable.

asciilifeform: and pedigree-preserving.

asciilifeform: incidentally i'm not entirely convinced that v gotta be married to a particular difftron to work.

asciilifeform: (any well-formed patch representation is, in principle, convertible to any other)

asciilifeform: foo.unix.vpatch

asciilifeform: foo.mirce_popescus_neato_difftron.vpatch

asciilifeform: etc

asciilifeform cleans 'a' key

asciilifeform: i do see the merit of nailing it down. but imho unix diff is retarded.

asciilifeform: because it mandates that no one ever use a programming lang where +++ occurs, etc.

asciilifeform: the reason i keep coming back to this thought is that unix diff results in some pretty barfy lisp vpatches.

asciilifeform: ben_vulpes might see what i mean

asciilifeform: magical-newlines (unix diff) and parens-sexpr (lisps) is a pretty heavy impedance mismatch.

asciilifeform: newline has ~0 syntactic meaning in lisps.

asciilifeform: (it is a form of whitespace)

asciilifeform: trb will probably remain in trad style 4evar

asciilifeform: unless folx ~really~ pine for the tabs fix thing...

asciilifeform: aha

asciilifeform: waiwat

asciilifeform: solved.

asciilifeform: phf: oooh yes

asciilifeform: '“‘Hi Nick, it’s Sam. The police are raiding my house,’” he said.'

asciilifeform: lulzy, brits haven't yet picked up the american tradition of cutting off victim's phones before executing a hit

asciilifeform: '“‘Sam, put your (expletive) hands up . . . They’re going to shoot you, Sam. Put your hands up.’” Cake said he told him. “‘OK,’” Maloney said calmly. ... “Right after that ‘OK’ there are four shots in succession — like pop, pop, pop, pop. No breaks, no more than four, no less than four also,” Cake recalled.'

asciilifeform: adlai: enlighten me, using earlier a/b sentences, what that'd look like

asciilifeform: ~exactly~

asciilifeform: (a differ that ~doesn't work at all~ on arbitrary textolade is a nonstarter)

asciilifeform: '“Somebody may want to ask the question as to why a pre-dawn, forced entry was necessary in this case,” Millar said , adding the public needs a full account of what happened Friday. (We) specifically want to know why a pre-dawn raid was required in a house with two young children.”'

asciilifeform: lelz

asciilifeform: 'because gestapo! stfu terrorist scum'

asciilifeform: mircea_popescu: in usa 'raid' is specifically a 'kick the dig until it bites, then shoot it' exterminator tactic against would-be cop shooters

asciilifeform: *dog

asciilifeform: they knock down door of d00d known to 'will shoot intruders' and of course machine gun barrage after he stumbles out of bed with old 12ga etc

asciilifeform: mircea_popescu: we had similar case right in this shithole town, victim was spared (though not his animals) only because he turned out to be... the mayor

asciilifeform: was, supposedly, 'mistaken address'

asciilifeform: i actually have insufficient data, after rejecting the available report as disinfo.

asciilifeform: so nm.

asciilifeform: iirc 'malcolm x' was executed in precisely the way described tho.

asciilifeform: mircea_popescu had a very spiffy article a while back

asciilifeform: 'antisocial struggle'

asciilifeform: what if every 'dawn raid' cop had a well-founded fear of claymore mine.

asciilifeform: (i predict: instead of door busting, they will simply do pre-dawn demolition charges from all sides, presto, 0 evidence)

asciilifeform: at any rate this is a stretch, most of the executed folk are no kind of desperado, have 0 weapon bigger than a fork

asciilifeform: (cops -- plant, on corpse, yes)

asciilifeform: su successfully bugsprayed oun-upa (ukr resistance)

asciilifeform: there is a famous case of red army d00d who killed dozen+ germans with axe.

asciilifeform: on same principle.

asciilifeform: aha.

asciilifeform: adlai: that looks painful

asciilifeform: adlai: your algo (not my encoding) suxx

asciilifeform: encoder ought to be aware that it shat a weight of encoderola ~equal to the fucking payload

asciilifeform: and refrain

asciilifeform: and emit:

asciilifeform: \xx-(foo bar baz)\xx+(foo (bar) baz

asciilifeform: nope

asciilifeform: same states

asciilifeform: just a less idiotic encoder

asciilifeform: mircea_popescu realizes that gnudiff encoding is also nonunique, neh?

asciilifeform: quite relevant though. it ~chooses~ a variant.

asciilifeform: even if idiotically, because designer was dropped as a baby

asciilifeform: like 'slut falls pregnant' eh

asciilifeform: which is dumb.

asciilifeform: to quote mircea_popescu 'i have nfi how my ancestors ended up with me, and anyone who claims to know this about self is full o shit'

asciilifeform: in other lulz,

asciilifeform: 'I think that it used to be fun to be a hardware architect. Anything that you invented would be amazing, and the laws of physics were actively trying to help you succeed. Your friend would say, “I wish that we could predict branches more accurately,” and you’d think, “maybe we can leverage three bits of state per branch to implement a simple saturating counter,” and you’d laugh and declare that such a stupid scheme would

asciilifeform: never work, but then you’d test it and it would be 94% accurate, and the branches would wake up the next morning and read their newspapers and the headlines would say OUR WORLD HAS BEEN SET ON FIRE. You’d give your buddy a high-five and go celebrate at the bar, and then you’d think, “I wonder if we can make branch predictors even more accurate,” and the next day you’d start XOR’ing the branch’s PC address with a shift

asciilifeform: register containing the branch’s recent branching history, because in those days, you could XOR anything with anything and get something useful...'

asciilifeform: '... You go to work hung-over, and you realize that, during a drunken conference call, you told your boss that your processor has 32 registers when it only has 8, but then you realize THAT YOU CAN TOTALLY LIE ABOUT THE NUMBER OF PHYSICAL REGISTERS, and you invent a crazy hardware mapping scheme from virtual registers to physical ones, and at this point, you start seducing the spouses of the compiler team...'
