mod6: Yeah, I get the pizarro ip for both A and MX records. Just in case, I have posted the clearsigned report to my website for viewing: http://mod6.net/2018/December/31/btcf_address_201812.txt
asciilifeform: unrelatedly : hey mircea_popescu , didja have a torrent tracker ? i seem to recall in the log ( tho cannot find. ) or was it an in-house thingie strictly.
asciilifeform: i ask because i have a 9GB disk image from that bolix 'macivory' ( recorded using the 'alpha' from earlier thrd ) but am reluctant to simply put on dulap, soaking up bw for errybody
asciilifeform: ( it's ~8GB gzipped )
asciilifeform: it aint that much good without the iron, but i would like the thing publicly gettable, given as i also baked a 'scsi2sd' config that eats the thing ☟︎
asciilifeform: ( solid state gadget that replaces the ancient whining hdd in the thing )
asciilifeform: lol holySHIT is gzip inefficient for disk snapshots. '7zip' gets it down to 256MB !
asciilifeform: possibly dun need torrents after all. ( it is nao smaller than those jpegs from last wk. )
mircea_popescu: asciilifeform wasn't a tracker, just a large box with the entire collection of trilema reviewed films. on for a year or so, but turned it off recently.
asciilifeform: aa
mircea_popescu: when realised that i do not like the "community" enough to pump 1k/mo into it or anything.
asciilifeform: aite.
asciilifeform: this is a fundamental problem with throwing up warez for 'public'. how to justify to self, the bird feeder.
asciilifeform: it costs real moneyz to throw up GBs.
mircea_popescu: http://trilema.com/2013/some-basic-discussion-of-charity/ what else.
asciilifeform: aha
mircea_popescu: nothing wrong with "here's a list of things you can have ~by request~ in my castle"
asciilifeform: this also. tho it is headachy to arrange in practice.
mircea_popescu: so asker must be this tall to ride.
asciilifeform: i mean on serving end.
mircea_popescu: when joe blow did enough for you that it overwhelms the headache, he can has.
asciilifeform: i have a half-written bot that takes a deedbot-style gpg wot decrypt and puts out a single-use emulated ftp login thing. but it is not alive, because gnarly in practice ( if single-shot, resumes dunwork; and no crypto, and prolly this is solvable but i dun have currently the time budget for massaging it )
asciilifeform: a reasonably-mechanized process for distributing warez to one's l1/l2 might be useful, but i haven't yet devised one that dun break in annoying ways in the field.
mircea_popescu: the correct way is reverse : take ~ftp login~, dump it in there.
asciilifeform: i.e. receiver puts up ftp ?
mircea_popescu: yup.
asciilifeform: i suppose that'd work ( tho still no crypto )
mircea_popescu: of course crypto.
asciilifeform: with what ?
mircea_popescu: with his key.
asciilifeform: as in, per file ?
mircea_popescu: per tarball, w/e.
asciilifeform: i guess would work.
asciilifeform: pretty heavy on the serving end, tho, needs scratch buffer of $file-length per each req.
asciilifeform: ( of much moar, in fact, than $file-length, cuz gpg is retarded )
mircea_popescu: you got collection-of-shit 1 throught 99. joe wants shit-item-5-6-7. joe sends !Z http://p.bvulpes.com/pastes/12345/?raw=true wherein is found "shit-item-5 ; shit-item-6 ; shit-item-7 ; pubkey"
mircea_popescu: you "shit-item-5 ; shit-item-6 ; shit-item-7" > tar > gpg -aer pubkey > joe.ftp.server
asciilifeform: right, it'd work in principle. but costly on transmitter end.
mircea_popescu: asciilifeform like this you can do it on an as-available basis.
asciilifeform: naturally as-available, how else.
mircea_popescu: WAY the fuck cheaper than alternative.
asciilifeform: but it won't be very available.
mircea_popescu: because www server will attempt to feed any clients at any time
asciilifeform: 7 folx want to load, each needs a, what, 4GB+ buffer (if turd is 1GB)
mircea_popescu: nah. it's a 20% overhead or so.
asciilifeform: classical gpg (base64) is a 400% neh
mircea_popescu: neh.
asciilifeform: ( assuming incompressible payload )
asciilifeform: given as most warez is already compressed
mircea_popescu: you don't even have to ascii armor, if that bothers you.
asciilifeform: this is prolly the most practical scheme suggested, to date, for this. but still feels heavy.
mircea_popescu: what can i tell you.
asciilifeform: also suffers from practical gnarl -- say the session gets thrown. how many times is the bot to retry upload.
mircea_popescu: until done.
mircea_popescu: ftp has resume, and besides, you got hashes.
asciilifeform: tru
mircea_popescu: and if it's such a problem, slice it.
asciilifeform: soon enuff we're back to alt.binaries lol
mircea_popescu: (if anyone wonders why all those r00 r01 etc slices back in the day)
mircea_popescu: asciilifeform correct design is correct design.
asciilifeform: oh hey remember the luby-style usenet archiver thing
asciilifeform: i fughet what it was called
asciilifeform: where you only needed e.g. 30 of 36 .rxx etc to magick the whole thing back into shape
mircea_popescu: i dunno anyone actually bothered.
asciilifeform: some defo bothered
asciilifeform: iirc it was a plain reed-solomon tho, not newfangled luby
asciilifeform: http://www.slyck.com/Newsgroups_Guide_PAR_PAR2_Files << found it. ☟︎
asciilifeform: 'PAR'.
asciilifeform: apparently there were even multiple versions of the thing, i had nfi.
asciilifeform: in the last days of the good old days, it was actually pretty common, in asciilifeform's recollection.
asciilifeform: 'golden age' of usenet may have ended in '93, before i even got hands on it, but 'silver age' imho ended ~decade later. ( when usenet more or less disappeared entirely )
mircea_popescu: you and naggum might've been the only ones left by then
asciilifeform: he outlived me there by considerable time.
asciilifeform was largely in lurk mode in those days, did not often presume to have what's worth saying.
asciilifeform: there was, however, warez. asciilifeform got most of his msdos-goldenage stuff from alt.binaries.*
asciilifeform: to round off the http://btcbase.org/log/2019-01-04#1884258 thrd : item confirmed to work. booted up box with it , it's a mixed blessing ( ~zero seek times, but slightly ~slower~ linear transfer than the mechanical disk. but, theoretically lasts '4evah', given as card can be easily backed up ) ☝︎

asciilifeform: i'ma post complete recipe laters.
asciilifeform: at the very least, it's quiet, and pulls 1watt instead of 40, reducing strain on the ancient electrolytic caps..
asciilifeform: phf i expect these will work in your 'xl' also.
asciilifeform: ( you can actually set arbitrary block size, so the weirdo 1280byte blox will work )
asciilifeform: the crapple ftr uses ordinary 512byte blks.
asciilifeform: when i first went to look for the thing, found that there's a whole underworld of vintage crapple people ( and 'amiga' etc ) , most of'em moved to using these things.
asciilifeform: ( interestingly also found that nowadays certain vintage crapples command 4fig prices. why -- cannot say. )
asciilifeform: there's folx running 'aix' even, that old favourite of BingoBoingo .

BingoBoingo: Mostly for what isn't on its gentoo
asciilifeform: well yes, sweet except for where it runs unixen
asciilifeform: BingoBoingo: possibly i said this before, but i am not fond of arm -- it is horrendously ugly, complex, single-vendored ( the multi-vendoritude is an illusion, they all use same british turd mask ) . i picked it as 'best horse in glue factory' for the application, is all.
BingoBoingo: Well yes, when all the race horses got tumors...
BingoBoingo: You're going to make a lot of glue
asciilifeform: BingoBoingo: all the race horses are dead. and we race , if you will, while dragging the carcasses around. so i prefer to go with the smallest when possible. ☟︎
BingoBoingo: asciilifeform: Yes, and the smallest ones also don't yeild much glue when boiled
asciilifeform: in other olds-noose, asciilifeform installed a http://btcbase.org/log/2017-06-27#1674958 , and it's pretty great. ty phf ! ☝︎☟︎

asciilifeform: ( tldr : plate of aluminum, with 0.5mm holes drilled. the working surface is ~edge~ of plate. )
asciilifeform: it's a compound lens.

mircea_popescu: oh!
asciilifeform: ( i.e. each hole refracts by fraction of degree. )

mircea_popescu: insanity.
mircea_popescu: right because discontinuous media is THE metamaterial for matter-wave interaction.
mircea_popescu: first fucking lesson in the field, what.
asciilifeform: hey it's how all other lensing worx.
mircea_popescu: you know ?
asciilifeform: 'least action path'(tm)
mircea_popescu: "so make it discountinous!" "HOW!!!" "dude drill a hole" "omfg how wise you are mr!"
asciilifeform: nao really one oughta ~etch~ the holes
asciilifeform: but basic principle remains.
mircea_popescu: drill and polish, i'd say, rather than etch. smoother holes this way\
asciilifeform: drilling 10e6 holes is a bit of a bitch
asciilifeform: but does apparently work.
mircea_popescu: laser! computor actuated! etc!
asciilifeform: aha, number of ways.
asciilifeform: tricky bit is, you want max sphericity
mircea_popescu: i'm totally like one of those old war veterans upon hearing of new weapon
asciilifeform: ( error magnifies exponentially )
mircea_popescu: starts wanting to dust off armors.
asciilifeform: mircea_popescu: was my reaction precisely.
mircea_popescu: this is worse than "czech glass, dummy. if you polish it like-so.." ftr. much, much worse.
asciilifeform: it's a 'the fucking key was in your pocket, lol' sorta wtf gem.
mircea_popescu: one day my car mechanic is going to come into this room, pour a quart of oil into the box, and make a whole new os this way.
mircea_popescu: then we'll all use that and all will be well.
asciilifeform: 1 application asciilifeform immediately thought of, discussed nowhere, is lightweight shielding ( need X times less square metrage of pb sheet as you have diff b/w focused and unfocused ! )
mircea_popescu: aha! could make some really cool shelters with this.
asciilifeform: was thinking moar along lines of 'fly on mars without frying' mega-puzzler, but yes
mircea_popescu: (likbez : problem with nuclear shelter is that Bremsstrahlung. but with this... well... make it go away)
asciilifeform: aha, as i undestand brems gets refracted along same vector as the orig photon
asciilifeform: so goes to the desired place.
mircea_popescu: (ie, you are MORE likely to die for being behind sheet lead/steel/whatever than not. because high energy electron won't hurt you at all -- or even see you -- but the tons of gamma it spews as the metal plate decelerates it WILL fucking fry you)\
asciilifeform: (notably ~not~ the case with grazing 'optics' )
mircea_popescu: asciilifeform exactly. fundamental reason why shelter ~= useless
asciilifeform: well traditionally 'shelter useless' cuz neutrons
mircea_popescu: you can afford to make plate thick enough to neuter those.
mircea_popescu: but all the classical films include "bottom of this here mountain" because do the math, one single electron can produce enough gamma to fry an egg
asciilifeform: neutron happily sails through 100m of iron, if enuff juice.
mircea_popescu: yes but on a power law.
asciilifeform: tru
mircea_popescu: if there's one meter of steel and two meters of you, 99.x% of all neutrons energetic enough to go through the sheet will ALSO be energetic enough to go through you
mircea_popescu: same would be true of electrons, too, except for the braking, which makes 99.x% of the energy of those NOT energetic enough to go through... take your picture.
asciilifeform: the prob is the .x% that capture
mircea_popescu: that is HOW the thickness of the sheet protects you from neutrons -- the thicker the sheet, the lower the loss into you. because that power law.
asciilifeform: ( observe that you dun need to cook the victim , like egg, he's just as dead when % of his Na turns to Mg etc
asciilifeform: )
asciilifeform: and naturally subj to power law, like anyffing else, or nuffin could live, sun would roast.
mircea_popescu: this is not factually true. leaving aside how nuclear explosion not nearly as harmful to people as commonly misrepresented (and let's see http://trilema.com/2011/radiatia-si-corpul-omenesc/#comment-44772 re this), there's precious few neutron casualties recorded. ☟︎
asciilifeform: the jp nukes were neutron-poor, tho
asciilifeform: ( and we dun have good body of 'experimental subject' from laters )
asciilifeform: but indeed, if anybody knows just how much neutron it takes to nail a man in militarily-relevant time frame, they aint tellin'
asciilifeform: it sux, tho, having to bury the dead enemy, + his furniture, walls, the ground his house was on, in pb coffins, to take the territory.
asciilifeform: hence why not so much interest, i suspect, in (misnomer, but) 'neutron bomb'
mircea_popescu: well, there's the dood with the sphere lol
asciilifeform: in moar mundane lulz, asciilifeform , after N-th vivisection of bolixtron, boots it up and finds that it turned into 'ordinary old crapple', i.e. no longer sees the card. thinks 'eh, shit', then -- remembers that it's a fuking '80s machine -- goes, cleans contacts. then finds, box again worx...
mircea_popescu: next time try drilling little holes
mircea_popescu: who knows.
asciilifeform: lol
mircea_popescu shall be now drilling holes in everything
asciilifeform: 'for 20kbux, i DRILL OWN HOLE!'(tm)(r)
mircea_popescu: lol. eh, i got some of those kitten scratcher things, can drill microholes on the cheap.
asciilifeform: btw electron beam makes exactly the sorta drill you want here.
asciilifeform: good sphericity, steerable, just-so diameter, etc
mircea_popescu: THE WARTENBERG RAKE!!!
asciilifeform: lol
asciilifeform actually has 1 somewhere..
asciilifeform: incidentally might be interesting to get that lens baked as... a pcb ( commercial pcb houses will do al instead of cu, at comparable cost , plus whatever drillings )
mircea_popescu: you're gonna roast yet.
asciilifeform: but 0.1% less!111
mircea_popescu: heh

asciilifeform: he uses a complement.
asciilifeform: ( for some reason did not use the standard name for it, why -- i do not know )
mircea_popescu: right, but he complement-decrements
asciilifeform: he straight-out complements.
mircea_popescu: o he does. he does. right you are, look at that.

mircea_popescu: "At each subsequent stage, the next number is the last N plus the last Z ; carries out of bounds are ignored ; if anything's ignored the next number's an N, otherwise a Z. " to take it out of the idiotic format.

asciilifeform: apparently nobody noticed.
mircea_popescu: and look at that, straight up induction proof.
mircea_popescu: did i mention i like your treasure trove finds a lot more these days ?
asciilifeform: i try to find the goodstuff!
mircea_popescu: flow diagram included.
asciilifeform: realize, this is ch.15.
asciilifeform: and directly affects how fast we can bake primes.
asciilifeform: ( and yes we'll bake primes without leaking the intermediates. which means that gcd eats full width of register, miller-rabin actually fires 9000 times , etc )
mircea_popescu: aha
asciilifeform: all i need nao is the proof that the thing needs F(B) turns of the crank to converge, where B is bitness of operands, and it's battlefield-ready.
asciilifeform: ( naturally not written as he wrote it, with the shaved additions, but with full widths. but still )
mircea_popescu: can not converge in more than 2^B turns.
mircea_popescu: there's your proof.
asciilifeform: mircea_popescu: this is troo for stein. but gotta show that this is isomorphic to stein.
mircea_popescu: think about it, if it converged in more than 2^B turns, then you'd have a B bit number contain B+k bits of information.
mircea_popescu: (ie, it's encode how many turns)
asciilifeform: well actually typo, stein converges in B shots.
asciilifeform: euclid's subtractor in 2^B, and therefore runs in geological time for bignums
mircea_popescu: ah, yeah. you want LINEAR F
asciilifeform: a usable gcdtron converges in B, or 2B, etc. shots, or it's rubbish
asciilifeform: correct.
asciilifeform: as in stein.
mircea_popescu: pretty sure it doesn't converge in B
asciilifeform: stein -- does
mircea_popescu: no i mean daykin
asciilifeform: ( it's in knuth v2 )
asciilifeform: it appears to, tho. but needs proof.
mircea_popescu: i think it converges in B or B+1 by parity
asciilifeform: that'd mean B+1
mircea_popescu: right
asciilifeform: ( recall how constanttimeization is done, when converged, you set the stopper and fz_mux outputs the answer , after that algo runs however many shots remain but without affecting the output )
mircea_popescu: well, i got other firepits to attend to, but what a great logmorning this has been!
asciilifeform: laters.
asciilifeform: in other lulz for the l0gz, python has some pretty ridiculous inbandisms. consider:
asciilifeform: >>> 511 + 8832
asciilifeform: 9343
asciilifeform: but:
asciilifeform: >>> 0511 + 8832
asciilifeform: 9161
asciilifeform: apparently it interprets the 05 as.. base prefix.
asciilifeform: somehow i used python for yrs as an adhoc calculator and had nfi this bomb were there.

asciilifeform: further upstack , i read http://btcbase.org/log/2019-01-04#1884475 and was waiting for mention of free-radical scavengers , e.g. WR-2721 and other variations on the theme, but didn't find.. ☝︎
a111: Logged on 2019-01-04 17:32 mircea_popescu: this is not factually true. leaving aside how nuclear explosion not nearly as harmful to people as commonly misrepresented (and let's see http://trilema.com/2011/radiatia-si-corpul-omenesc/#comment-44772 re this), there's precious few neutron casualties recorded.

diana_coman: http://btcbase.org/log/2019-01-04#1884512 -> last published paper seems to be from 1985, uni reading's website mentions him as part of "combinatorics @ Reading" but "retired" ☝︎
a111: Logged on 2019-01-04 18:33 asciilifeform: uni of reading, uk. wonder if d00d is still alive and within reach of diana_coman
asciilifeform: not very surprising
asciilifeform: most of the folx whose heads worked in 1970s, long ago reached end of working life
asciilifeform: ty for digging tho, diana_coman .
diana_coman: np, worth a dig anyway
