| nmz787 | juri_: so it seems you have posted to the google group about crashing and it seems no one else is working on this... :/ ugh, this is difficult to decide on what to use | 00:04 |

| juri_ | oh, that's so fixed... | 00:19 |
| juri_ | i've taken over as maintainer. | 00:19 |
| nmz787 | i am totally new to haskell as of downlaoding this | 00:19 |
| nmz787 | (also make test doesn't work for me, when replacing the _home var with ~/.cabal/bin/) | 00:20 |
| nmz787 | i am writing a test script in python now to generate stl | 00:20 |
| nmz787 | for them all | 00:20 |
| juri_ | this is my first haskell project. | 00:21 |
| juri_ | anyway, to bed with me. | 00:22 |
| ebowden | Night juri_. | 00:22 |
| nmz787 | 'night | 00:22 |

| nmz787 | archels: you do microfluidics? | 11:14 |
| nmz787 | before going to sleep I turned the quality on that mixer up from 2 to 3000 and it ended up producing an STL of 115 MB | 11:17 |
| kanzure | this is why you shouldn't use stl -_- | 11:18 |
| kanzure | but fine don't listen to us | 11:18 |
| nmz787 | the only other output it seems is STEP | 11:22 |
| nmz787 | for implicitCAD | 11:22 |
| nmz787 | my point was actually that the higher-res looks prety decent | 11:22 |

| nmz787 | kanzure: you did realize this is the source of the STL https://github.com/nmz787/microfluidic-cad/blob/master/implicitCAD/sinusoidal_mixer.escad | 11:28 |
| nmz787 | ? | 11:28 |
| eudoxia | i think kanzure doesn't like openscad either but i don't remember why | 11:29 |
| nmz787 | technically that is ExtOpenScad... though I'm not too clear of the differences | 11:29 |
| nmz787 | I'd like to figure out how to accomplish the same with cadQuery today | 11:30 |

| nmz787 | archels: I'm not sure a sinusoidal channel with constant wall spacing would still have edges that were sin waves though | 11:50 |
| archels | nmz787: nah, just dabble in CAD | 11:55 |
| archels | I think what I did back then was to take the sinewave as the centre of the channel, and project along a vector orthogonal to its derivative | 11:57 |
| nmz787 | mmm, yeah I was thinking it might be something to do with the derivative/tangential lines | 12:04 |
| nmz787 | center of channel didn't occur to me, but yeah sounds decent | 12:04 |

| nmz787 | kanzure: if svg was to be used, I think for things like that sine wave mixer there would need to be some internal representation... that way we could increase/reduce the quality as needed. Since it appears that you need to create things like a sine wave by evaluating the math yourself and drawing vectors | 12:30 |
| kanzure | then don't use svg for evaluation | 12:30 |
| nmz787 | and also you might want to adjust the channel parameters, like round cross-section, or square. | 12:31 |
| nmz787 | One thing that heekscad has is something called heekscnc, which made me think about edge effects during manufacturing | 12:31 |
| nmz787 | like, your beam or etch might not give you a straight wall or sharp corner | 12:32 |
| nmz787 | but maybe at a large enough resolution you don't even notice that | 12:32 |
| nmz787 | so it would be case dependent | 12:32 |
| nmz787 | and thus we should have a knob to adjust | 12:32 |

| kanzure | now that steve coles is dead they have been posting various plans to the grg mailing list | 14:42 |
| kanzure | the latest set of plans is for more donation drives | 14:42 |
| kanzure | "and getting more facebook likes" | 14:43 |
| kanzure | 1 like = 1 immortal | 14:43 |
| fenn | is that the new altcoin | 14:43 |
| kanzure | "likes" were a feature that facebook implemented in 1706 | 14:43 |
| kanzure | old timey times | 14:43 |
| kanzure | my point is that relying on donation drives to come up with your plans for life extension research and financing is not a good plan | 14:44 |
| delinquentme | how to fund life extension? | 14:44 |
| fenn | am i missing something here, why aren't there billionaires throwing piles of money at life extension research? | 14:44 |

| delinquentme | fenn, there are! but you must factor in coping mechanisms | 14:45 |
| fenn | i mean it's not like they can spend it on anything else | 14:45 |
| kanzure | i sent them a rant telling them they are morons and they should be planning for a project to take 100 years, or even 10,000 years | 14:45 |
| kanzure | because unreasonably colossal problems require unreasonably good plans | 14:45 |
| eudoxia | the grg people or the billionaires? | 14:45 |
| kanzure | grg people | 14:45 |
| kanzure | fenn is talking about the billionaires | 14:45 |
| kanzure | my best guess at this point is that billionaires don't have anyone good to spend the money on | 14:45 |
| kanzure | aubrey is not a bad person, but he's not going to hedge his bets correctly | 14:46 |
| delinquentme | billionaires struggle to vet talent | 14:46 |
| fenn | i wouldn't invest in a researcher who hedges his bets anyway | 14:46 |
| kanzure | there is no reasonable talent in this | 14:46 |
| kanzure | fenn: by invest you mean fund, and why not? | 14:46 |
| fenn | they have to be monomaniacally devoted to $(theory) in order to pursue it to completion | 14:46 |
| eudoxia | apparently some kind of {m|b}illionaire hired mike darwin to travel around the world collecting data on how fucked we are as a civilization | 14:46 |
| kanzure | cryonics and brain uploading, for example, what's not to like going after two hard things? | 14:46 |
| delinquentme | kanzure, what du mean about reasonable talent? | 14:47 |
| kanzure | and you don't just hire a single person obviously, but you do need at least one person that knows how to fucking plan | 14:47 |
| fenn | kanzure: well i was thinking you "invest" money and your return is not dying | 14:47 |
| kanzure | delinquentme: nobody has demonstrated any capacity for good planning for life extension research | 14:48 |
| fenn | other people not dying is a side benefit | 14:48 |
| kanzure | lots of people tiptoe around topics and they want to maximize youthfulness for 1000s of years, that's bullshit | 14:48 |
| kanzure | you really can't talk about things like extreme amounts of organ-specific life support systems, organ perfusion, replacement, organ markets, brain scanning, cryonics, as reasonable solutions to life extension, because people want some elixir or whatever | 14:50 |
| kanzure | perhaps actual life extension just sounds too ridiculous or something | 14:50 |
| fenn | did you read mike darwin's thing about "high technology" vs "futile technology" | 14:50 |
| poppingtonic | Can you really plan for things like this? Maybe the fact that nobody has demonstrated any capacity for good planning for life extension research means that we don't really understand the problems well enough *in principle* to plan for solving it. | 14:51 |
| kanzure | brain uploading in principle is a good plan for a dying body | 14:51 |
| eudoxia | it would probably be easier to convince people to fund WBE over cryonics, since cryonics requires, as darwin put it, commitment to the extent that a cryonics org should "be able to weather a war lasting centuries", while uploading is "scan & done" | 14:51 |
| eudoxia | well, you have to pay the power bills, et cetera | 14:51 |
| fenn | http://chronopause.com/chronopause.com/index.php/2011/05/30/going-going-gone/index.html | 14:52 |
| kanzure | cryonics does not require centuries -_- | 14:52 |
| poppingtonic | revival, maybe... | 14:52 |
| kanzure | you can run many wonderful cryonics experiments involving less than a whole month of suspension (or whatever the period is being called) | 14:52 |
| kanzure | you don't even need humans | 14:52 |

| eudoxia | well darwin has always been a bit of a fatalist, so he probably believes like eleitl there's a good chance of civilizational collapse | 14:53 |
| kanzure | civilizational collapse is another topic, in my opinion | 14:53 |
| kanzure | oops yes i don't know why i said a month | 14:53 |
| fenn | eleitl keeps harping about peak oil because he lives in germany and apparently nuclear power doesn't exist there | 14:54 |
| poppingtonic | you kinda want to factor XRisk in any future scenario, so I don't see a problem with that. | 14:54 |
| kanzure | nice "Polio victims on Iron Lung support in a school gymnasium in the mid-1950s" | 14:54 |
| kanzure | xrisk should not factor into my rant about doing basic projects -_- | 14:54 |
| eudoxia | well that's true | 14:54 |
| kanzure | "“Halfway technology represents the kinds of things that must be done after the fact, in efforts to compensate for the incapacitating effects of certain diseases whose course one is unable to do very much about. By its nature, it is at the same time highly sophisticated and profoundly primitive… It is characteristic of this kind of technology that it costs an enormous amount of money and requires a continuing expansion of hospital ... | 14:55 |
| kanzure | ... facilities… It is when physicians are bogged down by their incomplete technologies, by the innumerable things they are obliged to do in medicine, when they lack a clear understanding of disease mechanisms, that the deficiencies of the health-care system are most conspicuous…" | 14:55 |
| poppingtonic | so does he use civilizational collapse as a way to say "oh, but there may be bigger problems/priorities than cryonics.."? | 14:56 |
| kanzure | "A minority of scientists at that time believed that it might be possible to defeat Polio by the expedient of a vaccine,14 and so an intense competition for funds began between those who sought to secure more Iron Lungs to support the ever growing legion of patients with respiratory paralysis, and those who sought to understand the fundamental basis of the disease (in the context of their technological era) and treat it by eliminating it.15" | 14:56 |
| kanzure | i wasn't aware they were directly competing for the same money, that sounds dumb | 14:56 |
| poppingtonic | or is it in the interest of cryonicists and their supporters to work to reduce XRisk (or fund people who do)... | 14:57 |
| eudoxia | mainly he argues that cryonicists have been dreaming too much about Drexlerian nanotech, and successful, collapse-proof cryonics requires actual involvement of people in their cryonics providers | 14:57 |
| poppingtonic | kanzure: I wasn't saying that they're competing. I might have phrased that question in a bad way. | 14:58 |
| eudoxia | hmm, darwin hasn't posted anything on his blog for more than two years now, that's a shame | 14:58 |
| eudoxia | last i read from him in New Cryonet he was planning a post about embalming and chemical preservation that i was looking forward to read | 14:59 |
| poppingtonic | "When cryonics was conceived, the majority of people dying in the US did so with substantially intact brains; the incidence of dementia in people dying at the age of ~70 in the 1960s was ~1%.3 Currently, the incidence of dementia in Americans dying at the average lifespan (78.3) is ~30%" | 15:00 |
| kanzure | one of the paragraphs of my rant to grg was telling them that being more comprehensive about plans and hedges they can identify items that can accelerate life extension research | 15:01 |
| kanzure | for example, one of the major hurdles is the economic cost of molecular biology research | 15:01 |
| kanzure | by focusing on very cheap, very precise equipment, they can reduce those costs dramatically and get results across the board (not just in life extension research) | 15:01 |
| kanzure | (assuming that usable results would cost $100's of trillions of dollars, a 1000x reduction in basic research costs would be pretty damn great) | 15:02 |
| kanzure | ((although this is just one example of something that clever hedging can help with)) | 15:02 |
| fenn | "dammit jim, i'm a doctor, not an insturment designer" | 15:03 |
| kanzure | yes it is a little odd how most of grg are doctors | 15:03 |
| fenn | not really, seeing as how gerontology is a medical field | 15:03 |
| poppingtonic | re the quote, gerontology research (SENS) seems even more important now. | 15:04 |
| kragen | nuclear power no longer exists in germany, but I suspect that solar imported from Spain will make up the difference within a decade | 15:04 |
| fenn | kragen: i was being sarcastic; a blind spot doesn't make something just go away | 15:04 |

| kragen | also, doesn't cause earthquakes | 15:06 |
| fenn | how would geothermal cause earthquakes? | 15:07 |
| kanzure | poppingtonic: fwiw sens and gerontology or only partially overlapping | 15:07 |
| kanzure | but this distinction doesn't matter prolly | 15:07 |
| kanzure | *are only | 15:07 |
| kragen | fenn: enhanced geothermal extraction involves fracking, which induces seismicity | 15:07 |
| fenn | the problem is the word "gerontology" has been hijacked by do-nothings | 15:07 |
| kragen | e.g. the Basel program was abandoned due to induced seismicity | 15:07 |
| fenn | hm i figured "hot dry" were important for some reason | 15:08 |

| kragen | "hot" is important because it's heat energy you're interested in | 15:09 |
| fenn | meh those aren't real earthquakes anyway | 15:10 |
| kragen | "dry" just clarifies that we're talking about rock that you have to inject coolant into in order to get the heat out, unlike traditional geothermal where you just harness the steam coming out | 15:10 |
| delinquentme | offhand does anyone know what the market value of 1 gallon of rocket fuel in orbit is? | 15:12 |
| fenn | depends what it's made of, but around $40k | 15:13 |
| delinquentme | fenn any source on that? | 15:13 |
| fenn | just estimating at $10k/kg | 15:14 |
| delinquentme | I wanted to say I watched a video from some orbital mining company which I was far more impressed with | 15:14 |
| eudoxia | you guys should read The Rocket Company, it's a pretty good book about a hypothetical reusable rocket and it's on libgen | 15:15 |
| eudoxia | i like to think elon musk read it and was inspired by it to create spacex | 15:15 |
| fenn | there's nothing to mine in orbit but empty tanks | 15:15 |
| delinquentme | fenn, satellites which use fuel to maintain their positions / trajectories | 15:17 |
| fenn | presumably people would be pay more to put fuel IN the satellites | 15:17 |
| kanzure | almost as if hall effect thrusters might be useful or something | 15:18 |
| fenn | for low earth orbit you can use geodynamic propulsion, which is basically a reaction mass free ion drive | 15:19 |
| fenn | er, maybe i made that word up | 15:19 |
| delinquentme | ion drives are real | 15:19 |
| eudoxia | why waste money pumping fuel into satellites (many different satellites, with different kinds of tank, which aren't meant to be refueled), when you can just have a tiny tug go around, give satellites the occasional boost and be done with it | 15:19 |
| fenn | but the theory stands, since there are ions flying around in low earth orbit that can be co-opted | 15:19 |
| eudoxia | i mean, if you're going to refuel, you have to boost to the satellites and away from them | 15:20 |
| kragen | eudoxia: can you do that? | 15:20 |
| delinquentme | eudoxia, i want a satellite tug | 15:20 |
| delinquentme | =[ | 15:20 |
| kragen | hmm, good point | 15:20 |
| kragen | if you can refuel you can sat-tug | 15:20 |
| kragen | but you may not be able to do either very often | 15:20 |
| fenn | eudoxia: refuel once and the satellite can reboost many times | 15:20 |
| eudoxia | the fuel that you're pumping into the satellite would be better used tugging the satellite | 15:20 |
| fenn | otherwise you're lugging your own weight around for no reason | 15:20 |
| delinquentme | kragen, yeap you can... theres actually a really smart team working on asteroid 'extinction events' with that specitic tech | 15:20 |
| eudoxia | fenn: or you could retrofit electrodynamic cables to satellites | 15:21 |
| delinquentme | and curiously enough .. .just the passive mass of an object to ever so slightly deflect big mean asshole-roids | 15:21 |
| fenn | that's a good plan too | 15:21 |
| kragen | can you deflect asteroids by electrically charging them with a particle beam? | 15:21 |
| delinquentme | Oh and don't forget the spaceship and drilling and nuclear bombs and " I DOOONNTT wann misssa thang " | 15:21 |
| * delinquentme lelz | 15:22 | |
| eudoxia | i never got the whole argument "if we blow up an asteroid we'll just blow it into small still-deadly pieces" | 15:22 |
| kragen | presumably the charge will go away eventually because the solar wind is full of ions, but does that take a sufficiently long time to be useful? | 15:22 |
| eudoxia | sure, the total kinetic energy of the asteroid chunks will be the same, but with many chunks you have a better surface area to volume ratio | 15:22 |
| eudoxia | and more of the asteroid would burn up in the atmosphere | 15:22 |
| fenn | kragen what would the charge push against | 15:22 |
| kragen | fenn: other electrically charged bodies nearby? | 15:23 |
| * fenn thinks back to the early days of rocketry | 15:23 | |
| fenn | there's nothing nearby... it's space | 15:23 |
| kragen | I'm just thinking that sending electrons to an asteroid might be easier than sending solid objects including baryons to it | 15:23 |
| eudoxia | tbh we can just blow asteroids to smithereens and there's no need to resort to esoteric things like pulling the asteroid with the gravity of a probe | 15:23 |
| kragen | doesn't that depend on the timescale we're talking about, fenn? | 15:23 |
| eudoxia | kragen: you mean the solar wind? | 15:24 |
| kragen | eudoxia: I did say "the solar wind" at one point, but I'm not sure if that's the point you're asking about | 15:24 |
| fenn | given a choice of shooting an asteroid with electrons or a laser, the laser is better because there is no blurring of the beam due to like charge repulsion | 15:25 |
| kragen | I mean we're talking about objects with chaotic orbits, which is the whole reason we're not sure if they're going to hit us or not in the first place | 15:25 |
| eudoxia | a negatively charged asteroid braking against the positively-charged solar wind | 15:25 |
| kragen | eudoxia: hmm, I hadn't thought about that approach | 15:26 |
| eudoxia | it probably wouldn't work, it would just be an extremely inefficient magnetic sail | 15:26 |
| fenn | it wouldn't be magnetic at all | 15:26 |
| fenn | the helium particles would go straight at it | 15:27 |
| kanzure | those iron lungs were probably made from military scrap metal | 15:27 |
| kragen | fenn: if you can develop a charge on the dark side of the asteroid that persists for years, you can exert a force on it over years | 15:27 |
| fenn | i wonder if an electrodynamic tether would work with solar wind as the charge carrier | 15:27 |
| kragen | while a laser will only be exerting a force on it at the time that it is shining on it | 15:28 |
| kragen | unless you can somehow use the laser to charge the asteroid, e.g. ablating the parts of the asteroid with one or another net charge | 15:28 |
| fenn | kragen this happens on the moon at sunrise/sunset already | 15:29 |
| fenn | the dust shoots hundreds of meters up, then presumably contacts the solar wind and falls back down | 15:29 |
| kragen | that's interesting | 15:30 |
| fenn | that was the point of LADEE, to study what happens | 15:30 |

| kragen | we can't divert those, unlike asteroids, unless we have some way to figure out that they are about to happen; and they'd destroy enough of the ozone that the surface biosphere would be mostly destroyed, far worse than any asteroid impacts we've had so far | 20:45 |

| nmz787 | i wonder if tesla's idea of charging the ionosphere would have any effect | 20:46 |
| nmz787 | i guess not | 20:46 |
| nmz787 | they aren't charged | 20:46 |
| nmz787 | we could pump some gamma absorber into the atmosphere | 20:46 |
| kragen | like what? | 20:50 |
| kragen | if we knew in advance maybe we could do something | 20:50 |
| kragen | but our current theory is that we would have no advance warning | 20:51 |
| nmz787 | hmm, have you studied optical heterodyning more yet? maybe we could just blast the sky with a laser :P | 20:58 |

| nmz787 | "Some polar liquids, such as nitrotoluene (C7H7NO2) and nitrobenzene (C6H5NO2) exhibit very large Kerr constants. A glass cell filled with one of these liquids is called a Kerr cell. These are frequently used to modulate light, since the Kerr effect responds very quickly to changes in electric field. Light can be modulated with these devices at frequencies as high as 10 GHz. Because the Kerr effect is relatively weak, a typical Kerr cell ... | 21:12 |
| nmz787 | ... may require voltages as high as 30 kV to achieve complete transparency. This is in contrast to Pockels cells, which can operate at much lower voltages. Another disadvantage of Kerr cells is that the best available material, nitrobenzene, is poisonous. " | 21:12 |
