asciilifeform: 'work hardening', yes
asciilifeform: it is more or less impossible to anneal (and, opposite, harden) all but the smallest objects in 'jungle conditions'
asciilifeform: and annealing.
asciilifeform: (or with a 'knife' in the general sense)
asciilifeform: point of the above unfinished tale is, most of the difficulty of machining as a field revolves around the unwanted sequelae of having to cut metal with metal.
asciilifeform is satisfied with conventional lathe. but milling is another matter
asciilifeform: (but he's a thinking man; no idea what 'maker derps' do)
asciilifeform: he owns a cnc mill, the size of a tv set.
asciilifeform: is diametric awake?
asciilifeform: decimation: they do.
asciilifeform: tungsten carbide is brittle. but - yes, trivially.
asciilifeform: if you're fine with waiting a year for the, e.g., pistol, draw 1 amp instead of 1000.
asciilifeform: also scales down. (but no one, afaik, has scaled it.)
asciilifeform: and the hardness of the material being cut doesn't matter at all - so long as it conducts.
asciilifeform: no need for exotic cutters or quality slides
asciilifeform: in materials, pauper-cheap.
asciilifeform: expensive but only in electrical current.
asciilifeform: it was a response to the nato embargo on selling 6-axis milling machines to the sovblok.
asciilifeform: this was perfected in ussr, and the only vendor of electrolytic mills (which could trivially 'etch' small - or large - arms of whatever kind, on a desktop) is still russian.
asciilifeform: electrolytically.
asciilifeform: speaking of which, time for today's 'sovietism.' not one english-speaking fellow i've met seemed to know, that you can machine arbitrarily hard metals with no cutting elements (no noise, no wear, no need for massive ballscrews or slides, etc.)
asciilifeform: as i recall, locklin's observation was that 'printed' gun is a technowankerous curio, vastly inferior to an aggregation of discarded plumbing parts and a rusty nail
asciilifeform: hans eysenck's 'psychoticism'
asciilifeform: (too 'cold' in the simulated annealing sense. i.e., not psychotic enough.)
asciilifeform: ^ old discussion of why china failed to technoclobber europe
asciilifeform: http://log.bitcoin-assets.com/?date=19-02-2014#515199 ☝︎
asciilifeform: possibly
asciilifeform: !s simulated annealing
asciilifeform: like many successful/creative types, he had a 'red dwarf phase' of life
asciilifeform: (so it isn't entirely clear that he was wrong)
asciilifeform: diode logic is a complete logic, incidentally.
asciilifeform: 'Shockley was the only one to publicly acknowledge his donation to the sperm bank.' (pediwikia)
asciilifeform: shockley did, if i recall, hit upon the idea of building a sperm bank to.. hand out own sperm
asciilifeform: not an uncommon pattern
asciilifeform: howard hughes (around same time)
asciilifeform: (or derp on 'reddit')
asciilifeform: in modern usa, noyce would rot in own juices in a psychiatric ward.
asciilifeform: there we go.

asciilifeform: damn
asciilifeform: !s большая зона
asciilifeform 'east cost corporations' << had the distinct impression that most of the people here never had to walk the u.s. большая зона
asciilifeform: decimation: philo farnsworth invented the raster scan while plowing a field. there's always a weirdo exception.
asciilifeform: '…like a refugee from very rural Pakistan who gets relocated to Oslo, Norway, and still thinks that he could make better food if he were only allowed to light a fire in his living room instead of using that complex electric stove. (This is a real news item. Every now and then, landlords discover indoor fireplaces and occasionally the “newbies” to civilization burn down the building.)' (herr naggum) ☟︎☟︎
asciilifeform always supposed that it was because they cannot have proper 'division of labour'
asciilifeform: they merely have access to seemingly-inexhaustible old war spoils
asciilifeform: decimation: nope.
asciilifeform: reload.
asciilifeform: decimation: they can machine, weld, assemble own parts from scrap << sure. but can they build so much as a kalash round with own hands, to the required tolerances?
asciilifeform: nope
asciilifeform: 'efficiency' - 'takes function arguments.' efficiency at what, for whom.
asciilifeform: if we actually get the tech for rural non-simpletonism (keep own pigs -and- bake own 14nm cores) - we'll learn
asciilifeform: are these entirely separable?
asciilifeform: (how many of the latter still work - a different question)
asciilifeform: decimation: ground-based gizmo obsoleted by orbital spybots
asciilifeform: unattainable goal << their modus operandi is to cripple people in any available way, to inject 'relevancy.' no reason to think this won't continue with better tech.
asciilifeform wonders when ocean fiber reamplifiers will begin to include a few kg of trotyl with motion fuse, for meddlesome buggers
asciilifeform: ^ beautiful example of u.s. media hush campaign. vanished entirely from nearly everywhere within days of first mention.
asciilifeform: decimation: or recall the chinese sub that test-fired ballistic rockets off the california coast recently.
asciilifeform: for the 1000 ships tactic, the vessels must be properly autonomous
asciilifeform: fix RuBisCO, from its current ~2% efficiency to something like 50+ - and now you needn't the massive resupply points that make fat targets.
asciilifeform: interesting fact, i think we might have spoken of it before - usg claims extraterritorial jurisdiction over... all ships.
asciilifeform: might want to wait for 'SOSUS' to finish falling apart before setting sail on microsubs
asciilifeform: (sea water conducts)
asciilifeform: you can charge inductively under the sea, but parasitic currents are a drag
asciilifeform: there's two basic types of 'permission' - one where you can, without permission, but might catch some lead; and one where you actually can't ('promise vs. protocol')
asciilifeform: today she'd own one of those radio-controlled insertables.
asciilifeform: nubbins`: teacher had no pockets? or, no hands ?
asciilifeform: this applies just as easily to the nominally 'proper' education (average peon has very little use for, e.g. arithmetic)
asciilifeform: in square meters << must specify, folded or denatured.
asciilifeform had occasion to go to a local electronics store a few days ago, '3d printers' were displayed right next to ordinary ones.
asciilifeform: probably being '3d printed' to order even as we speak.
asciilifeform: people would fuck their own severed heads if they could.
asciilifeform: lol!
asciilifeform: when the last u.s. boat hits the bottom, the scrapyards, or the chinese auction block - we'll find out whether the 'seastead' folks are serious.
asciilifeform: or, as with one proposed electromobile, battery swap couriers.
asciilifeform: batteries.
asciilifeform: the same kind of tech problem as the absence of pocket laser pistol.
asciilifeform: (given current battery tech, this is unlikely to change)
asciilifeform: a non-nuke sub spends 90+% of time on the surface.
asciilifeform: (mr mold on the 'seasteading' concept. http://unqualified-reservations.blogspot.com/2009/05/democraphobia-goes-slightly-viral.html)
asciilifeform: eed to love the sea. Spend a little time with Moitessier, Slocum, and the like; read this fine collection, and possibly this (pretty much all of Jonathan Raban's books are good); etc, etc. Yes, I'm aware that seasteading is not yachting. I'm aware that no one intends to take their floating poles around Cape Horn. But you are still at sea, and a subject of Neptune you remain.'
asciilifeform: 'Defined in these terms, when you move onto a floating pole somewhere in the ocean, the first effect on your freedom is a massive decline. You have sworn fealty to King Neptune. Neptune accepts your service, as he has accepted so many before you. His court is glorious, his riches are infinite, his territory is vast. But Neptune is a stern and capricious lord. To live at sea, you need not just love liberty. You n
asciilifeform can't imagine why
asciilifeform: we could be there already, but somehow it appears that most people don't like the sea very much.
asciilifeform: the familiar 'water planet' scenario, yes.
asciilifeform: generally, you want two men (one sleeps)
asciilifeform: ;;google kaiten submarine
asciilifeform: and, who doesn't love the japanese 'Kaiten.'
asciilifeform: midget subs are 1930s state of the art.
asciilifeform: and the 'two airplanes theorem' (what can two planes do, that one, regardless of how spiffy, cannot? be in two places.)
asciilifeform: silent on battery.
asciilifeform: cost.
asciilifeform: (electrolytic cell, sea water)
asciilifeform: just like sailors on a nuke sub never need to surface for air - only for food/ammunition/parts
asciilifeform: well, everyone with the necessary apparatus.
asciilifeform: (see also this: http://log.bitcoin-assets.com/?date=02-08-2014#781699) ☝︎
asciilifeform: mircea_popescu: to fully visualize the logical conclusion of that gedankenexperiment, picture if one could subsist entirely on the output of a 'desktop garden' under a fluorescent lamp.
asciilifeform: DERP << still waiting for some muppet to start a company selling bottled piss or the like, and labeled 'bitcoin'
asciilifeform doesn't quite grasp why hatchet jobs are necessary against electromobiles - they do a fine job sucking on their own
