asciilifeform: When everything was ready and the cup was placed in the vessel, Lilavati suddenly out of curiosity bent over the vessel and a pearl from her dress fell into the cup and blocked the hole in it. The lucky hour passed without the cup sinking. Bhaskaracharya believed that the way to console his dejected daughter, who now would never get married, was to write her a manual of mathematics!'

asciilifeform: 'Lilavati was the name of Bhaskaracharya's daughter. From casting her horoscope, he discovered that the auspicious time for her wedding would be a particular hour on a certain day. He placed a cup with a small hole at the bottom of the vessel filled with water, arranged so that the cup would sink at the beginning of the propitious hour.

asciilifeform: ( http://www-history.mcs.st-andrews.ac.uk/history/Biographies/Bhaskara_II.html << subj, for the intrepid )

asciilifeform: ( from 'Lilavati', c. 1150 ad, Colebrook transl., )

asciilifeform: in other olds, ''Whilst making love a necklace broke. / A row of pearls mislaid. / One sixth fell to the floor. / One fifth upon the bed.'

asciilifeform: http://btcbase.org/log/2017-06-18#1671900 << every time i see these, immediately think of those ww2 'surrender nao' leaflets ☝︎

asciilifeform: enlarge hole in chassis as needed

asciilifeform: alsoo pete_dushenski you can use selftapping woodscrews

asciilifeform: http://btcbase.org/log/2017-06-18#1671888 << oughta ask phf, perhaps he has this pill ( iirc has both openbsd and crapple in active use ) ☝︎

asciilifeform: http://btcbase.org/log/2017-06-18#1671920 << paging BingoBoingo!111! ☝︎

asciilifeform: !~later tell pete_dushenski didja ever get your FG going ??

asciilifeform: curl http://idiocy.gov | /bin/bash still Worx Great!111 tho

asciilifeform: ( and so 'gardeners' are not really a thing, here in monkeystan )

asciilifeform: funnily, i could easily afford, say, a gardener, but refuse to pay the equivalent of 8 gardeners so that obummercare and shameekas.

asciilifeform: the only actual solution is to leave the accursed jail. but so far aint got to where.

asciilifeform: BingoBoingo: still not magic pill, the weeds happily grow in it, even taller than the grass per se

asciilifeform: 'neighbour's grass' is part of the mandatory fantasyland these folx live in

asciilifeform: didn't fly

asciilifeform: we actually had a d00d here who did this

asciilifeform: not-having-grass is also banned around here

asciilifeform: BingoBoingo: if you can find me an agentorange where the bloody shit STAYS GREEN 4evah, i'll buy for its weight in silver.

asciilifeform: or biweekly.

asciilifeform: i ain't doing this weekly.

asciilifeform: as in weekly

asciilifeform: BingoBoingo: i got one. problem is that it needs SCHEDULE

asciilifeform: would , but won't satisfy city hall's 'max length'

asciilifeform: the humble grass cutter went the way of the pc -- you get to choose between affordable rubbish and 'must amortize and work this for pay' golden toilet

asciilifeform: the petrol-engined things, aside from vibration ( can't use my hands for day+ after ) and acrid smoke , also made of shit, i've thrown out 2 (after attempting various orc repairs, cleaned carb etc) in frustration

asciilifeform: mircea_popescu: these work great maybe in sane house where ground is straight and not 1,001 items for cord to catch

asciilifeform: and takes 4x longer to charge than discharge..

asciilifeform: story gets even moar pathetic, the battery (i shit thee not) died in my 'furca' for 2nd time today

asciilifeform: naturam expellas furca (tm)(r)

asciilifeform: did read, lol.

asciilifeform: *beam

asciilifeform: ^^

asciilifeform: esp if the latter worked on city hall et al

asciilifeform: BingoBoingo: i'd luvv to mow with flamethrower. or disintegrator mean.

asciilifeform: and the mosquitoes, ground wasps, other lovelies

asciilifeform: mircea_popescu doesn't live in 'green hell' where ~100% humidity and 40c

asciilifeform: back upstack -- i spend considerable time doing this and similar nonsense because : high-friction

asciilifeform: ( they are right here, as we speak, devouring )

asciilifeform: funnily enough it's already set to bird

asciilifeform: mircea_popescu: actually i have my cutter set to 'in-place'

asciilifeform: ferroconcrete.

asciilifeform: BingoBoingo knows very well that none of this 'hay' goes anywhere but city dump, at considerable expense

asciilifeform: somehow it is not permitted to have houses reasonable distance apart from one another, without bunch of green liquishit in the middle

asciilifeform: actually problem is the theme park of usa 'suburbia' demands this peculiar prop, 'mass of grass'

asciilifeform: aha, how else

asciilifeform: sorta goes back to mircea_popescu's 'who gets to bend around the schedule of what' item

asciilifeform: the only offered variant is 'subscription and it happens during business hours when you, idiot, are sitting in the room an' trying to work'

asciilifeform: the funny bit is that the needed commercial arrangement 'i call on a saturday and it happens THIS MOTHERFUCKING HOUR while i'm out to dinner' is not available where i live

asciilifeform: and 1,001 hills.

asciilifeform: BingoBoingo: not if you let it go for ~year

asciilifeform: and still not done

asciilifeform: ~all

asciilifeform: and so asciilifeform spent much of today cutting motherfucking grass.

asciilifeform: not everybody has mircea_popescu's ultralowfriction pairs of auxiliary hands.

asciilifeform: http://btcbase.org/log/2017-04-30#1650052 << that one ☝︎

asciilifeform: mircea_popescu: recall the thread with the gardener ?

asciilifeform: the operative concept is 'for money'

asciilifeform: and not fixated on, e.g., conveyor belt or whatnot trappings

asciilifeform: mircea_popescu: i'm quite familiar with the original meaning of the word

asciilifeform: lol

asciilifeform: of whatever description.

asciilifeform: mircea_popescu: problem with this pov is that certain classes of things ~only~ can ever happen in a serious-kitchen, and will never in factory.

asciilifeform: aah

asciilifeform: well you did say 'own shop' so i pictured.

asciilifeform: mircea_popescu: the pets do own shocks, brakes, etc. work ??

asciilifeform brb

asciilifeform: ( spoiler : ultimately we are dealing with ~multiword~ ops, and the complexity of how the multing actually happens, comes into play )

asciilifeform: btw iirc this is an ~actual~ exercise in knuth -- to show that you still need karatsuba on a box where add(word,word) takes same time as mult(word,word)

asciilifeform: nope.

asciilifeform: karatsuba et al weren't even working with computers. but wrestling with question of how much, abstractly, work, does multiplication per se entail.

asciilifeform: aha.

asciilifeform: mircea_popescu: actually it remains relevant even if single-word mult is (as it is on some boxes) 1 cycle, same as add

asciilifeform: aha

asciilifeform: (four would be the obvious but useless transform)

asciilifeform: basic idea is that k's algo transforms a N-bit O(N^2) mult, into instead ~three~ (N/2)-bit mults

asciilifeform: knuth uses base10 in his overview, aha

asciilifeform: mod6: aha, my recipe uses (noshit.jpg) base2

asciilifeform: mircea_popescu is using base10 in his example but otherwise right

asciilifeform: ( there are not and will not be signed arithmetic in ffa )

asciilifeform: now my recipe is arranged a little bit differently from, e.g., knuth's , so that we can forget about signs

asciilifeform: )

asciilifeform: ( we did not recurse, in this example, explicitly, but if you had -- you would have k := ceil((bitness of x and y)/2) naturally in each level of recursion

asciilifeform: if it weren't obvious, k = 16

asciilifeform: ( apologies for l0g clutter, but gotta do this !!)

asciilifeform: and we're done.

asciilifeform: 0xfffffffe00000001

asciilifeform: p2*(2**32) + (p1-p2-p0)*(2**16) + p0 ==

asciilifeform: p2 = X1*Y1

asciilifeform: p1 = ( (X0 + X1) * (Y0 + Y1) )

asciilifeform: p0 = X0*Y0

asciilifeform: sooooo:

asciilifeform: which is ~34~ bits

asciilifeform: (X0 + X1) * (Y0 + Y1) == 0x3fff80004

asciilifeform: which is 17, and not 16 bits

asciilifeform: X0+X1 == Y0+Y1 == 0x1fffe .

asciilifeform: nao for the bitch :

asciilifeform: X1Y1 = 0xfffe0001
