BingoBoingo: Maybe alf needs to mow with a more fun machine?
mircea_popescu: but yes, upstack : the ability to say "here, do this. ok, you'll be doing this from now on until further orders" is invaluable.
asciilifeform: and the mosquitoes, ground wasps, other lovelies
mircea_popescu did some grass cutting, enjoyed being out with the trees
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
BingoBoingo: Spz you want to plant tomatoes? Now you need 2-cycle concrete saw and rotary hammer before you can even till!
asciilifeform: mircea_popescu: actually i have my cutter set to 'in-place'
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'
BingoBoingo: Anyways, the problem is excess of services amoratizing 10-50 kilodollar monsters and few amoratizing 21" machines
BingoBoingo: <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 << The is lawnmowing service since the exit of children is priced based on amoritization of mowing equipment
mircea_popescu: all my shit goes back to all my olther shit, it's crazy. i was just contemplating this earlier.
asciilifeform: sorta goes back to mircea_popescu's 'who gets to bend around the schedule of what' item
mircea_popescu: asciilifeform used to be local kids. but now local kids are too precious cuntlets to let out of deepfreeze
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'
BingoBoingo: <asciilifeform> BingoBoingo: not if you let it go for ~year << That isn't mowing. That is harvesting hay. Hope the crop was dry.
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
BingoBoingo: Come on it's a standardized 30-45 minute task or your lawnmower is the wrong size
BingoBoingo: How "much of today"?
asciilifeform: and so asciilifeform spent much of today cutting motherfucking grass.
a111: Logged on 2017-04-30 13:58 asciilifeform: 'If I employ a gardener, I have to earn £3 for every £1 he can actually spend, because everything is taxed twice, first as my income, then as his.' << not only still true in today's reich, but today it'd be 10 : 1 .
asciilifeform: http://btcbase.org/log/2017-04-30#1650052 << that one ☝︎
mircea_popescu: gthe one making tomatoes on windowsil ?
asciilifeform: mircea_popescu: recall the thread with the gardener ?
BingoBoingo: <mircea_popescu> which brings the mixing : putting orange in green engine is bad. orange engine can run with green fine << Orange engine runs green fine, IF orange is drained out.
mircea_popescu: which is why if my place costs 100 to rent and 80 to man, it will be open 24/7 and so it will cost 100 to rent and 240 to man.
BingoBoingo: <mod6> im not sure why they switched to the new coolant. they always just said, "lasts longer, etc." but i wonder if it was really due to the proliferation of aluminum blocks. << Dex-cool is silicate free so gentler on Aluminum. Also something something organic/inorganic dopants differing between verde and naranja
mircea_popescu: but if i buy coffee grinder for factory, it is to work at all times, and girls will change their schedule to keep it going, not it to accomodate them. ☟︎
mircea_popescu: if i buy coffee grindewr for kitchen, it is to work whenever the girls want coffee ground.
mircea_popescu: sure, originally. what i had in mind above is that your idea of "serious kitchen" is probably my idea of factory but without any capital goods management.
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
mircea_popescu: tho potty humour aside, i suspect the actual dispute is re the meaning of factory
mircea_popescu: hey, in theory no difference between sextoy's anterior and posterior openings. in practice she sometimes winces.
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.
mircea_popescu: that's kinda my objection with the whole "in my kitchen" outlook. if your kitchen makes stuff that's any good it should be a factory, and if not it should forget about it and just be a kitchen
asciilifeform: mircea_popescu: the pets do own shocks, brakes, etc. work ??
mircea_popescu much rather buy used and then put these new at own shop than buy "certified" bla bla and have to put new ones anyway in coupla years
mod6: you fixin up the bmw?
mod6: mircea_popescu: this is actually what a guy at auto store told me recently too; but other fellas have told me, "if you wanna be 100% sure you're not going to introduce any problems, just use what it says in the manual or on cap."
mircea_popescu: shinohai cardboard car for looking at not for driving in the rain.
shinohai: So apparently all one needs to destroy a US destroyer is container ship: http://archive.is/4GbGw ☟︎
mircea_popescu: which brings the mixing : putting orange in green engine is bad. orange engine can run with green fine
mod6: asciilifeform: thanks for the hex example.
mod6: im not sure why they switched to the new coolant. they always just said, "lasts longer, etc." but i wonder if it was really due to the proliferation of aluminum blocks.
mod6: anyway, the wisdom seems to be, use what's described in the manual or even written on the radiator cap. fwiw, never open a radiator cap while engine is hot - contents under pressure.
mod6: post, most seem to now use this "dex-cool" stuff which is pink or orange. you are not supposed to mix them, no. and as bb says, can introduce rust into the water jacket of the block.
mod6: <+BingoBoingo> <mircea_popescu> i bought a can of coolant, it's FLUORESCENT GREEN << he dye is to tell you which of several incompatible types of coolant it is. Mixing GREEN and ORANGE coolant is a good way to introduce rust to one's engine block cooling passages. << iirc, all vehicles pre-1995 or so used the green coolant. ☟︎☟︎
BingoBoingo: <asciilifeform> possibly the practice had spread to auto world << Coolant color coded with dye. Refrigerant available with optional dye for leak finding.
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)
mircea_popescu: if single - word mult is same as add, there's no benefit to not simply multing the parts.
mircea_popescu: this is only relevant because machines do mults in like 18x the time they do adds.
mod6: apparently this ends up being O(N^ln 3) or something
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
mircea_popescu: but yes alf is correct i did base 10 for convenience because most people don't have base 2 mult table loaded in head so dunno what 110 * 101 is
mod6: just was overthinking it .. thought maybe the '2' was a base reference or something
mircea_popescu: mod6 the thing with these is always some little insignificant nook that gets caught
mod6: mircea_popescu: yup, gotcha, that short hand threw me through a loop for a minute. lol.
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
mod6: <+asciilifeform> if it weren't obvious, k = 16 << this seems to make sense
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: ( apologies for l0g clutter, but gotta do this !!)
asciilifeform: nao for the bitch :
mod6: if i FOIL this thing (10 + 1)(10 + 1), i get: 10*10 + 10*1 + 1*10 + 1*1; 100 + 10 + 10 + 1 = 121. ooh, is see what you did there.
mod6: <+mircea_popescu> trivially, 11 * 11 = 121, and also (10 + 1) * (10 + 1) = 10 * 10 + 2 * 10 * 1 + 1 * 1 = 121. << what I can't figure out is where the part: + 2 comes from.
a111: Logged on 2017-06-17 17:55 asciilifeform: immediate 'argh' because we set out to operate SOLELY with M-bit FFA.
mircea_popescu: http://btcbase.org/log/2017-06-17#1671504 this one ☝︎
asciilifeform: the carry from the addition ? nope
mircea_popescu: asciilifeform this was going to be my next line of inquiry. can the above discussed +1 bs be lost if we simply enforce a conveniently chosen size ?
asciilifeform: ...if all of your ffa are 'clean' powerof2-sized, you can lose the floor/ceiling thing
mod6: mircea_popescu: ok thanks.
a111: Logged on 2017-06-16 23:07 lobbes: <mircea_popescu> use supybot carcass then << aye. 'tis what lobbesbot (and I think jhvh1) run on, sina
shinohai: http://btcbase.org/log/2017-06-16#1671180 <<< 'tis correct, though I am still working on switching it to lispbot as time permits. ☝︎
mircea_popescu: because obviously if we're cutting up 11, the first part will be 1 and the second part will be 1.
mircea_popescu: shifts are mults by powers of two in binary, basically.
mircea_popescu: mod6 you take a number of say 22 bits, and cut it in two 11 bit numbers. this 11 is the k. then you have first part * 2 ^ K (=11) + second part to get the original back
shinohai: One of those Argentines mircea_popescu raves about I see.
m0n0lake: i don't need no voice , thanks shinohai
mircea_popescu: ben_vulpes but do the math for signal power used in eg FM radio, then figure what the satellite would have to send.
shinohai: Epic logs I missed over past ~2 days .... especially phf's lecture this a.m.
mod6: is this like taking the low-order bits of X0*Y0 << 2*(WORD_SIZE), and (((X0+X1)*(Y0+Y1) - X0*Y0 - X1*Y1) << WORD_SIZE ?
mod6: asciilifeform: can you explain what K is and why we need to shift by it?
mod6: I guess, it doesn't cover karatsuba specifically, but gives some background perhaps for the uninitiated.
mod6: ok. so there looks to be a section on this in AoCP Vol 2. section 4.3.3. [ Section A ]
asciilifeform: couldn't source a set of lcd glasses that had usefully high switching speed.
asciilifeform: lulzily, long ago, asciilifeform tried to make use of this principle to build a sunglass for seeing lappy lcd in bright sunlight ( sync lcd shutter, a la 'game glasses', to the backlight pwm freq )
asciilifeform: whereas if you're a kid and naively build a thing that tries to close a relay when infrared diode sees light and conducts dc -- it will work for maybe a metre, no moar, distance
asciilifeform: receiver samples at the carrier freq (typically 40 or so kHz), and then processed as serial bits.
asciilifeform: concept is usually taught in re radio but applies just as readily in optics -- say, the common infrared remote button
asciilifeform: idea of pll is that you can indeed see a lit match from mile away in daylight if you know 'exactly when to look' ☟︎☟︎
ben_vulpes: did not know the signal was that quiet
jhvh1: asciilifeform: What is phase - locked loop ? - Definition from WhatIs.com: <http://searchnetworking.techtarget.com/definition/phase-locked-loop>; Phase Locked Loop Tutorial | PLL Fundamtentals | Radio ...: <http://www.radio-electronics.com/info/rf-technology-design/pll-synthesizers/phase-locked-loop-tutorial.php>; MT-086: Fundamentals of Phase Locked Loops ... - Analog Devices: (1 more message)
asciilifeform: ( if you own, e.g., 'gps' receiver, you already own an example of a device that picks up a signal BELOW motherfucking THERMAL noise!1111 )
