--- Day changed Tue Aug 12 2008 01:06 < fenn> oblivierra seems like a half-cooked "millenial project" (LUF) 01:07 < bkero> Does it even have a domain anymore? 01:08 < fenn> uh, i mean the atacama desert colony, not the mmorpg 01:09 < bkero> I see. 01:10 < fenn> i'm reading logs from a couple days ago 01:10 < bkero> Google fails me. 01:10 < fenn> http://heybryan.org/chats/chats/agaboogamonger_Mar5th02005.html 01:10 < fenn> probably not all that interesting 01:11 < fenn> one problem with these self-sufficiency projects is they always consider the 'unit' to be geographically located, but the real world provides different environments that are conducive to different activities 01:12 < fenn> and so humanity has ended up with trade 01:12 < kanzure> plastic from silicon or something silly like that 01:12 < kanzure> actually it was from algae IIRC 01:12 < fenn> nothing wrong with that, but you have to consider the reasons behind it 01:13 < fenn> is it worth trying to make your own plastics? 01:13 < fenn> what is the cost in freedom vs the cost in labor 01:13 < bkero> Depends on what your goal of civilization is 01:13 < fenn> (freedom from mail order catalogs and UPS) 01:13 < bkero> If you're content with an agrarian society I'm sure it's not too difficult if you chose the right location. 01:14 < fenn> right now the US is finally taking a look at this sort of question re: oil 01:15 < bkero> The extreme left responds to "We're fucked" reports. Everyone else tends to ignore them. 01:16 < bkero> Until it starts to very quickly change the country to third world status. ;) 01:16 < fenn> even george W bush says the US needs to break its dependence from foriegn oil, so i wouldnt say it's the extreme left 01:16 < bkero> Then everyone else tries to find some other reason for it happening, because "We told you so" is too embarrasing. 01:17 * kanzure glances at the screen to his immediate left ... still scrolling with papers. 01:17 < kanzure> :)) 01:19 < bkero> "We have a problem with our dependency on foreign oil. Clearly the problem isn't with our land yachts and lack of foresight retarding environmental regulation and > 6000lb vehicle 80% tax treaks. It has to do with everyone else in the world using more, not us. This problem has not existed until now, everyone else was just waving flag for the wrong culprit." 01:20 < kanzure> if I was more energetic at the moment I'd go into a spiell about recursive publics and fully surveying available resources before exponentially cancering yourself 01:21 * bkero is using no oil besides what it takes for my good to get to the grocery store 01:21 < kanzure> doesn't matter ... dependency loops. 01:21 < fenn> if i could, i would.. that's why i'm joining the raelians to get the first shot at cloning! :) 01:21 < bkero> Yup 01:21 < kanzure> dependency-loops, not a statement that they do loop (of course they do, but no) 01:22 < kanzure> we've been able to clone for a while though 01:22 < kanzure> so why join them? 01:22 < fenn> who's we? 01:22 * bkero bicycles and drives an electric car. :) 01:22 < fenn> afaict even the raelians havent cloned anyone 01:22 < kanzure> we = everybody but me, in a lab 01:22 < kanzure> ah, well, people 01:22 < kanzure> ok 01:23 < kanzure> I'm assuming the SCNT diff between hu/sheep/ape is minimal 01:23 < kanzure> the technique has to be roughly the same 01:23 < kanzure> except perhaps chemical prep work 01:23 < fenn> has anyone succeeded in cloning sheep/ape that isnt all old and fucked up? 01:24 < kanzure> http://home.cfl.rr.com/chaosdriven/references.html 01:24 < kanzure> hm 01:24 < kanzure> mice? 01:24 < bkero> Least fucked up big cloned thing I've seen was probably a frog back in the 70s. 01:25 < kanzure> http://heybryan.org/transhuman/cloning/ 01:25 < kanzure> http://heybryan.org/transhuman/cloning/RefSalSCNT.zip 01:25 < kanzure> http://heybryan.org/transhuman/cloning/CRi%20SCNT%20Full%20Protocol%20Final.pdf 01:25 < kanzure> http://heybryan.org/transhuman/cloning/Enucleation%20Rhesus%20Monkey%20MPEG4v2.avi 01:25 < kanzure> etc. 01:25 < fenn> but.. are they viable? 01:25 < fenn> dolly was as "old" as the original sheep 01:25 < kanzure> check out the zip file 01:26 < kanzure> lots of awesome references with links to pubmedcentral 01:26 < kanzure> the dolly problem was largely because of tolemerase 01:27 < kanzure> 'Cloned creatures are cloned from diploid cells (2n) and when they divide (those diploid cells) they produce an organism exactly like the cells that they came from. In order to produce Dolly the sheep, it took over 4000 individual nuclear replacements of the cell - 01:27 < kanzure> to get them all to divide the same. Insert references to the Alien movies. Don't see Alien versus Predator - horrible. The problem with cloning is that it is a very inexact science. In order to get one good Dolly sheep it takes many thousands of attempts.' 01:27 < kanzure> http://heybryan.org/school/Biology/notes/output.html 01:27 < kanzure> 'Cholesterol-based hormones (steroid hormones) are rapidly absorbed in muscle cells and many other cells. The positive effect is that they turn on genes for proteins to be built, but the problem is that it wears out the division mechanisms like with Dolly that caused increased aging rate.' 01:28 < fenn> sometimes you really do behave like a HMM robot 01:29 < kanzure> Dolly related: 01:29 < kanzure> http://www.mblwhoilibrary.org/services/lecture_series/campbell/bibliography.html 01:29 < kanzure> http://www.ncseonline.org/nle/crsreports/03Apr/RL31211.pdf 01:29 < kanzure> Who to blame for Dolly: http://www.nottingham.ac.uk/biosciences/anphy/lookup/lookup_role.php?id=NjA0MjI0&page_var=publications&pubs=all&unit_id= 01:29 < kanzure> (his email address and such) 01:29 < kanzure> Wasn't there that dog cloning organization from the early 90s? 01:30 < kanzure> Some rich guy's dog was going to die, so he hired a team of 10 men to clone the bitch. 01:30 < kanzure> quite literally. 01:30 < bkero> haha 01:30 < bkero> There are a lot of businesses out there that preserve dogs DNA to be cloned when it's economically viable. 01:30 < fenn> can i get my dog's brain frozen? 01:31 < kanzure> there was an article on this in the toolkit 01:31 < bkero> It's not the freezing that kills the cells, it's the thawing out :P 01:31 < kanzure> oh, wait 01:31 < kanzure> no 01:31 < fenn> uh, no it's the freezing 01:31 < kanzure> omg omg omg 01:31 < bkero> o? 01:31 < fenn> it's the crystals, man! 01:31 < fenn> oooo 01:31 < kanzure> http://heybryan.org/docs/cache-index.txt 01:31 < kanzure> Bioelectric discharges of isolated cat brain after revival from seven years of frozen storage.pdf 01:31 < kanzure> ok, found it 01:31 * kanzure feels better. 01:33 < kanzure> http://heybryan.org/~bbishop/docs/Bioelectric%20discharges%20of%20isolated%20cat%20brain%20after%20revival%20from%20years%20of%20frozen%20storage.pdf 01:33 < bkero> SCIENCE! 01:33 < kanzure> :) 01:34 < kanzure> hm, pdx.edu 01:34 < kanzure> that's where nchaimov is 01:34 < kanzure> why isn't he in here? 01:34 < kanzure> oh, heh. he's the one who retrieved the file for me. :) 01:35 * bkero is in portland too 01:39 * kanzure is more worried about the artificial wombs .. cloning seems ok so far, but these damn tanks seem to mutate the cargo 01:40 < bkero> Why not just use real wombs? 01:40 < bkero> Seems optimal for nutrient delivery. :P 01:40 < kanzure> bkero: Suppose you were using a von Neumann probe and flying across the galaxy. 01:40 < kanzure> Assume cryonics isn't working out too well (oops) 01:40 < kanzure> you'd have to have live supplies of women and their "real" wombs 01:41 < fenn> artificial womb needs an artificial heart, glandular system, kidneys, etc etc 01:41 < kanzure> as if the fact that it's attached to women makes them any more real, except in that we currently have them I suppose 01:41 < kanzure> artificial womb is just a tank sort of 01:41 < kanzure> let me get the Kuwabara refs 01:41 < kanzure> close but not it: http://www.uni.edu/~maclino/cl/skinner_baby_in_a_box.pdf 01:41 < kanzure> http://www.amazon.com/Ectogenesis-Artificial-Technology-Reproduction-Inquiry/dp/9042020814 01:41 < fenn> they dont have to be 'real' kidneys, just something that performs the same function. but kidneys seem like an efficient use of space and energy to me 01:41 < bkero> fenn: You merely need to produce the outputs of those. :P 01:42 < kanzure> http://www.newscientist.com/article/mg13418180.400-japanese-pioneers-raise-kid-in-rubber-womb-.html 01:42 < kanzure> there we go 01:42 < kanzure> http://www.amazon.com/Ectogenesis-Artificial-Technology-Reproduction-Inquiry/dp/9042020814 01:42 < kanzure> http://www.babytron.com/ 01:42 < kanzure> http://www.geocities.com/placenta_rb/Biblio.html 01:42 < kanzure> http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2007/09/22/neggs122.xml 01:42 < kanzure> http://www.aec.at/festival2000/texte/nobuya_unno_e.htm 01:42 < kanzure> http://www.mindfully.org/Technology/2005/Faking-Babies-Reproduction19may05.htm 01:42 < kanzure> http://www.eshre.com/CM.NET.WebUI/CM.NET.webUI.SCPR/SCPRfunctiondetail.aspx?confID=05000000-0000-0000-0000-000000000029&sesID=05000000-0000-0000-0000-000000002074&absID=07000000-0000-0000-0000-000000014605 01:42 < kanzure> http://www.newscientist.com/article.ns?id=mg19526146.200&feedId=online-news_rss20 01:42 < kanzure> for bonus points, the second one is the raelians :) 01:42 < kanzure> (babytron) 01:42 < kanzure> More: http://www.nrlc.org/Killing_Embryos/ArtificialWombs.html 01:42 < kanzure> http://www.fictionwise.com/ebooks/eBook1011.htm 01:43 < fenn> i find it curious that the only people publically advocating human cloning are UFO kooks 01:43 < fenn> why is this a taboo? 01:43 < kanzure> hm 01:43 < bkero> Can't we just have organ sacs for the purpose of feeding the fetus? 01:43 < kanzure> bkero: What? 01:44 < bkero> Autonomous sacs of organs for an artificial womb. :P 01:44 < kanzure> fenn: maybe it's because nobody has actually seriously proposed some projects or something ... something nonprofit would be needed methinks 01:44 < kanzure> bkero: Maybe. There's the tissue engineers that we could go abduct and have them make those 'sacs' you're talking about. 01:45 < bkero> fenn: It's taboo because it raises all sorts of ethical questions by people who don't understand science, but question what kind of rights it should have, and if it has a 'soul'. 01:45 < kanzure> I've always wanted to try 'exploded organism emulation' via having mostly biological components except separated by long distances with networking hardware of some sort or another in between, just so that it could all be modular and stuff. ;-) 01:45 < kanzure> why are 'rights' even a question ? 01:45 < kanzure> is that the right question to be asking? 01:45 < fenn> why would DNA makeup have anything to do with whether it has a soul? 01:45 < bkero> Could I clone myself for a housemaid? 01:45 < kanzure> I dunno, could you ? 01:45 < fenn> your clone would grow up just like any other baby 01:45 < kanzure> wrong question ;-) 01:46 < fenn> you can name your kid 'ben' but that doesnt make him the same as you 01:46 < kanzure> hint of angst there ? 01:46 < bkero> True, but could you breed 'subhumans' with less rights? 01:46 < kanzure> there's a scale of rights ? 01:46 < bkero> There used to be. 01:46 < bkero> And there still is in a portion of the world. 01:47 < kanzure> And how do you map genome to this scale ? 01:47 < fenn> they already did that in america in the 1800's 01:47 < fenn> no cloning needed 01:47 < kanzure> I don't know what 'subhuman' means :-/ 01:47 < bkero> Subhuman is more of a social distinction than a biological one. 01:48 < bkero> See: Eunechs 01:48 < fenn> what do you call a human with less performance, ie the opposite of transhuman 01:48 < kanzure> "Control, an illusion, and order our comforting lie; Through chaos, from chaos, into chaos we fly." 01:48 < kanzure> human with less performance 01:48 < kanzure> but you see, that's kind of assuming there's a performance thingy 01:48 < kanzure> erm 01:48 < bkero> Could it be a human with less value? 01:48 < kanzure> "better human" and "worse human" just doesn't make sense to me. It's the same reason why GPA doesn't make sense. 01:49 < kanzure> value to *who*? 01:49 < kanzure> It's context-dependent, remember. 01:49 < kanzure> *you're* the one making the value judgment 01:49 < kanzure> (or somebody else yelling at you) 01:49 < fenn> quality of subjective experience? 01:49 < kanzure> ? 01:49 < fenn> say i'm blind and deaf and numb and hate my life, obviously my subjective experience is of a lesser quality 01:49 < fenn> OR IS IT! 01:50 < kanzure> I don't understand. 01:50 < kanzure> are you asking me to tell you that I'd kill you or something ? 01:50 < fenn> i'm slightly undecided, but i think it's OK to argue that lesser subjective experience means that your life is inherently worth less 01:50 < bkero> kanzure: If he were that disfunctional, he would be of little value to society, however his quality as a human could be great. 01:51 < fenn> i dont mean value as in what sort of contributions i can make 01:51 < kanzure> this problem space is confusing and sucks 01:51 * kanzure ignores it. 01:51 < bkero> Heh 01:51 < fenn> because eventually we will all be obsoleted by AI 01:51 < bkero> As soon as singularity bootstraps itself. 01:51 < bkero> I'm waiting it any day now. 01:51 * kanzure points out that we're probably the bootstrappers sort of 01:52 < kanzure> if you looked at exp.html for instance.. it's one of the lazy projects we've been kicking around for a few months 01:52 < fenn> kanzure: i got in an argument with an economist once 01:52 < kanzure> how'd you survive? 01:52 < fenn> er, something like that 01:52 < fenn> not a real economist, just someone who thought he was one 01:53 < fenn> anyway 01:53 < fenn> the argument was about how much your life is worth 01:53 < fenn> he said that you could determine what monetary value the person placed on their life by measuring risks and the amount of money put into reducing those risks 01:54 < bkero> You know you're right that my eyes sort of glazed over when reading that 01:54 < bkero> Er, I'm not entirely sure that's accurate. 01:54 < bkero> That's assuming risk reduction is the primary goal 01:54 < fenn> say you are a thug, with 50% chance of getting killed tomorrow 01:55 * kanzure hates the concept of 'risk' 01:55 < kanzure> procto knows :) 01:55 < kanzure> and probability 01:55 < fenn> you could buy a gun for $100 that would reduce your risk of dying by 50% 01:56 < fenn> you could buy another gun for $1000 that would reduce your risk by 99% 01:56 < fenn> so, assuming you have $1000 and dont buy the fancy gun, you can estimate the value you put on your life at somewhere between $50 and $1000 right? 01:57 < fenn> blah 01:57 < bkero> That's not even fallacious, that's just dumb. 01:58 < fenn> it's dumb because people have an invincibility bias, they dont believe they can die 01:58 < bkero> fenn: I don't know about you, but I'm not going to die. 01:58 < fenn> well, i'm not dead yet am i? 01:58 < bkero> But do you think you will? 01:58 < fenn> i dont know, i'm death-agnostic 01:59 < bkero> http://www.ted.com/index.php/talks/aubrey_de_grey_says_we_can_avoid_aging.html 01:59 < fenn> yeah yeahh your're preaching to the choir 01:59 < bkero> :P 01:59 < fenn> anyway the whole point of this was that weiwe should value human life insttrinissically 02:00 < fenn> intrinsically* 02:01 < fenn> but then saying "human life" is sort of arbitrary, so i've generalized it to subjective experience 02:01 < fenn> for all the fuzzy bunnies and whales and dolphins and robots 02:01 < bkero> Although I have to say that in an appropriately welfared society, we wouldn't have to put any surmountable amount of money into life extension. 02:05 < fenn> "I don't worry about the ethical problems. I just want to rescue the fetus where it is impossible to be rescued by present treatment" 02:05 < fenn> sad state of affairs 02:06 < fenn> hey kanzure we could lobby conservative anti-abortionists to develop artificial wombs, the rationale being that unwilling mothers wouldnt have to kill their fetuses 02:07 < bkero> Is the state going to pick up the bill for them? :P 02:08 < kanzure> not bad 02:08 < fenn> no, the rich religious nutjobs would 02:08 * kanzure recently met Aubrey in person :) 02:08 < bkero> You can't get rich religious nutjobs to pay for anything besides their 44,000 sqft creationist museum in kansas. 02:09 < fenn> bkero: then they could see the reality of the cost of bearing a child, and the guilt would be on them for not contributing, see? 02:09 < bkero> Guilting rich republicans, I like it. 02:09 < fenn> "you murderer, sending this innocent fetus to its death!" 02:09 < bkero> Of course they're simply going to claim 'its not a child' 02:09 < fenn> now if only i could figure out how to apply this to space development 02:09 < fenn> but they can't claim it's not a child 02:10 * bkero met burt rutan 3 years ago. :) 02:10 < bkero> fenn: They could claim it's not human because it lacks a soul(somehow) 02:10 < kanzure> who's burt? 02:10 < kanzure> the mothers would argue otherwise 02:10 < fenn> bkero: its not a cloned fetus, just a regular aborted (or would-be aborted) fetus 02:10 < bkero> He designs ultralight aircraft, and spaceshipone 02:10 < fenn> raised in an artificial womb 02:11 < kanzure> bkero: ultralight, like scramjets? http://heybryan.org/mediawiki/index.php/Scramjets 02:11 < fenn> not ultralights, homebuilt small airplanes 02:11 < fenn> you need a pilot's license of some sort to fly the *EZ 02:11 < bkero> fenn: I get that, but they could claim that it has neither a nurturing mother or father, it's a humunculous 02:12 < fenn> wtf the whole point of pro-life is that the fetus is worth saving 02:12 < fenn> the mother wants to kill it 02:12 < bkero> My ex girlfriends father has an ultralight in his garage. I helped him cut the styrofoam, vacuum bag it, and assemble it. 02:13 < bkero> We built one of these: http://en.wikipedia.org/wiki/Long-EZ 02:14 < fenn> cool, that's my favorite homebuilt design i think 02:14 < bkero> Hehe, it's what john denver died in 02:14 < bkero> Burt Rutan basically wrote ALL the books on experimental aircraft. 02:14 < fenn> yeah i read the report, it was stupid 02:14 < bkero> I'm a member of 2 EAAs. The Electric Auto Association, and the Experimental Aircraft Association 02:17 < kanzure> bkero: I'll be over in 10 hours 02:17 < bkero> The aerodynamics of the Long-EZ are such that it's the same as pushing a 2sqft block through the air 02:17 * kanzure wants to see. 02:17 < bkero> haha 02:18 < bkero> I don't actually own the plane. I'm way too fucking poor. I'm still getting a pilots license. 02:18 < fenn> i have a hard time understanding why planes cost so much 02:18 < fenn> they're very simple 02:19 < bkero> Because they're made of composites, which don't have cheap manufacturing processes. 02:19 < bkero> You can roll steel and stamp aluminum 02:19 < fenn> that's not true, cessna's are made of stamped aluminum and are just as expensive 02:19 < bkero> You have to mold styrofoam then lay fiberglass on both sides of that, then epoxy it, then seal it in a bag, and run a vacuum to remove excess epoxy. 02:20 < bkero> Cessnas also demand a price premium, you pay for their product marketing. 02:20 < bkero> They're also not 'experimental'. 02:20 < fenn> experimental or not, airplanes are expensive 02:21 < bkero> Yea, those long-ez's are $35000 :/ 02:21 < bkero> Because they require a substantial bit of engineering? :P 02:22 < bkero> A piece of shit will roll, but a piece of shit won't fly. That's why engineering on planes is infinitely better than cars. 02:22 < fenn> $35k isnt too bad, that's about what someone would pay for a car 02:22 < bkero> Finished in 1985 02:22 < bkero> Then again, nobody has built substantially better planes since then. :/ 02:22 < bkero> For fuel mileage, the Vari-EZ still holds the record. 02:23 < fenn> but i'm talking to these aero-engineers who make $100k/yr and can't afford to fly 02:23 < bkero> They use fucking air-cooled Beetle engines. 02:23 < bkero> (and get better mileage than the beetle) 02:24 * fenn ponders a turbo diesel homebuilt 02:24 < bkero> airplane or car? 02:24 < fenn> airplane 02:24 < fenn> i'm interested in using a turbo diesel as the generator for a serial hybrid car tho 02:25 < bkero> http://www.deltahawkengines.com/journa00.shtml 02:25 < bkero> Already been done 02:25 < fenn> hard to find small high efficiency diesel engines for cheap-ish though 02:25 < bkero> http://www.evxteam.org/index.php?option=com_content&view=article&id=2&Itemid=25 02:25 < bkero> Not if you tear them out of old VWs. ;) 02:26 < bkero> Electric motors are up to 98% efficient. Gasoline/diesel motors are up to 26% 02:26 * kanzure sleeps 02:26 < fenn> VW engine is too big 02:26 < fenn> big engine == car bullshit 02:26 < fenn> you end up designing the car around the engine 02:26 < bkero> Riding lawn mower? 02:28 < fenn> hmm that "hybrid supercar".. what were they thinking? couldnt afford supercapacitors so they tried to use lead acids instead? 02:28 < bkero> Supercapacitors don't story energy for very long. :/ 02:28 < bkero> They dissapate really fast. 02:29 < fenn> it says their batteries didnt provide enough power 02:29 < bkero> lol 02:29 < procto> kanzure: I don't hate concepts :> though there are concepts that I hate seeing implemented 02:29 < bkero> Lead acid batteries are really good at discharging TONS of amps at once. 02:30 < fenn> but not enough for this supercar, apparently 02:30 < bkero> The only thing that's gotten close is LiFePO3, and that's about 12x as expensive. 02:30 < fenn> what about NiCd? 02:30 < bkero> Nope 02:30 < fenn> seems to me that batteries shouldn't be used for power buffering 02:31 < bkero> NiCads discharge at about 0.75C. That means if it's a 12v 2000mAh battery, it the maximum that it can discharge is 24W 02:31 < bkero> Er, 24 * 0.75 02:31 < bkero> Batteries are used for power storage, capacitors are used for energy storage. 02:32 < bkero> Capacitors discharge on their own significantly faster though. 02:32 < fenn> uh, express that in SI units please 02:32 < fenn> "Batteries are used for power storage, capacitors are used for energy storage." 02:33 < bkero> Capacitors are great at being charged very fast with a lot of electricity. They can also discharge equally quickly, but they don't store it that well. Think of how you're supposed to wait 5 seconds after you shut your computer off to turn it back on. That's the caps discharging themselves. 02:34 < bkero> Batteries are the exact opposite. 02:34 < fenn> that's a resistor across the capacitor terminals dissipating the energy stored in the capacitor, it's a safety feature 02:34 < fenn> the capacitor doesn't have any internal leakage (not nearly as much as a battery anyway) 02:35 < bkero> But if I go and charge a capacitor to however many farads it's going to hold, and measure the wattage in there after 1 second, it's going to be significantly higher than 1 minute. 02:35 < fenn> not true 02:36 < fenn> and your units are all wrong 02:36 < bkero> Which unit? 02:36 < bkero> (s) 02:36 < fenn> if you charge a 1 farad capacitor to 12V it will stay at 12V for a very long time 02:37 < bkero> But if you put a known load on it, it can sustain the load longer if it was just charged 02:38 < fenn> if it was charged recently you mean? 02:38 < bkero> yes 02:38 < fenn> basically you are arguing that the equivalent parallel resistance of a battery is higher than a capacitor 02:39 < fenn> why oh why is this data so hard to find 02:42 * bkero shrugs. I've had this conversation before with people asking about superconductors as a remedy to the problem of charging electric cars. 02:43 < fenn> "The self-discharge of the supercapacitor is substantially higher than that of the electro-chemical battery. Typically, the voltage of the supercapacitor with an organic electrolyte drops from full charge to the 30 percent level in as little as 10 hours. 02:43 < fenn> Other supercapacitors can retain the charged energy longer. With these designs, the capacity drops from full charge to 85 percent in 10 days. In 30 days, the voltage drops to roughly 65 percent and to 40 percent after 60 days." 02:43 < fenn> so, i was wrong. sorry 02:43 < bkero> S'no problem 02:43 < bkero> I'm surprised to see it that high though. 02:43 < bkero> THey'd be really good in electric dragsters. :) 02:44 < bkero> "Look how many amps i can dump!" 02:44 < bkero> I've thought of picking up some supercapacitors, they're about $200 on digikey iirc 02:46 < bkero> 100F 2.7V are $15. 02:46 < bkero> I'd need 14 of them to power my bicycle 02:47 < fenn> ESR is a critical parameter 02:47 < bkero> 10 mOhm 02:48 < bkero> Is that the rate of dischareg? 02:48 < bkero> *discharge 02:48 < bkero> (or internal resistance) 02:48 < fenn> its resistance 02:49 < fenn> hmm that could work 02:53 < bkero> F=(A*sec)/V 02:53 < fenn> at 8kW total you'd dissipate 400W in the capacitor 02:54 < fenn> but 8kW isn't a steady state condition so it's sorta hard to estimate heat sinking requirements 02:54 < bkero> It disappates as heat, and 400w is a shitton of heat 02:54 < fenn> and also you have to consider the thermal conductivity of the insides of the capacitor 02:54 < bkero> 400w would be doable by a really big heat sink. My processor does about 210w 02:55 < fenn> also, you'd only get 20 sec of "thrust" 02:56 < bkero> Which is plenty for a dragster, but not so much a car. :P 02:56 < fenn> ya 02:56 < fenn> but you said bicycle so i assume there's some kind of regenerative braking 02:56 < bkero> Nah, I'm using a cheap motor. 02:56 < bkero> I'm using 2 36v 15Ah batteries, an ebay 750w motor, and a MY1020 750w motor 02:57 < bkero> *ebay controller 02:57 < fenn> then why use supercaps at all? 02:57 < bkero> I hadn't looked into that very much 02:57 < bkero> To put a really fat back tire on the bike and do burnouts 02:57 < bkero> Although supercapacitors would be excellent for taking regenerative braking 02:58 < fenn> well 750W isnt enough to do burnouts :0 02:58 < bkero> Priuses should use it for regen. :/ 02:58 < bkero> It is on a tiny skinny bike tire. 8) 02:58 < bkero> 745 watts = 1 horsepower 02:58 < bkero> 1 horsepower and < 100lbs 02:59 < fenn> i think i've seen remote controlled cars with >1hp 02:59 < bkero> 1 horsepower will get me up to around 22-30mph depending on if it's completely full or half empty 03:00 < bkero> Voltage drop on lead-acid batteries is aboslute shit. 03:00 < fenn> use a boost converter? eh nevermind 03:00 < bkero> I'd like to replace this pack with lithium ion cells, but that's expensive AND NOBODY MAKES BATTERY HOLDERS FOR THEM!!!! 03:01 * bkero ordered a 10 pack of 18650s on ebay last week to replace the ones in his aging iBook. 03:02 < fenn> i just never unplug my laptop 03:02 < bkero> That's pretty bad for the battery. I've ruined 2 in my powerbook that way 03:02 < bkero> If you never unplug it, I'd recommend taking the battery out. 03:03 < fenn> why? 03:03 < bkero> Battery chargers(even smart ones) maintain float voltage on the batteries. 03:03 < bkero> They burn off the top electrolyte 03:08 < bkero> The battery on my macbook is 9 months old, and the battery holds 5091mAh. The battery was originally rated for 5020mAh. 03:08 < bkero> It has 300 load cycles on it 03:09 < fenn> remaining capacity: 299 mAh 03:09 < fenn> it seems to cut that number in half each time i run on battery power 03:09 < fenn> that's "fully charged" 03:10 < bkero> errr 03:10 < bkero> What's 'original capacity'? 03:10 < bkero> / design capacity 03:10 < fenn> i think 2000-3000, not sure how to find out 03:10 < bkero> cat /proc/acpi/battery/BAT0/state 03:11 < fenn> present: yes 03:11 < fenn> capacity state: ok 03:11 < fenn> charging state: discharging 03:11 < fenn> present rate: 800 mA 03:11 < fenn> remaining capacity: 299 mAh 03:11 < fenn> present voltage: 12330 mV 03:11 < bkero> Hum, strange. 03:11 < bkero> Look up your model laptop on google. :P 03:11 < bkero> 300mAh is staggeringly bad though. My 2005 iBook is at 72% original capacity, and goes up to 3100mAh. 03:12 < fenn> i'm sorta wondering how it comes up with that number 03:13 < fenn> looks like it was probably 3600mAh 03:13 < bkero> The ACPI controller on your motherboard shows it to the bios 03:16 < fenn> i want a laptop that takes AA batteries, is that so hard 03:16 < bkero> It's entirely doable. 03:17 < bkero> You'd need 16 AAs to get a decent sized laptop battery 03:18 < fenn> that's about the same as what's there now 03:18 < bkero> The Li-ions in there now are 3.7V * 2000mAh 03:18 < bkero> That's what's been used in laptops for the last 5 years or so 03:19 < bkero> AAs can't be recharged that many times. :/ 03:19 < bkero> Sorry, rechargables are 1.2V. You'd need 20 to get a decent sized battery 03:20 < fenn> what do you mean 'decent'? 03:20 < bkero> Would last more than 1.5 hours 03:20 < bkero> At 1.2V you'd need 10 to get up to 12V. Then you have 12V * capacitory of a single cell 03:21 < bkero> Put 2 of those strings in parallel and you have 12V * double the capacity of a single cell 03:21 < fenn> ok, so NiMH AA batteries are like 2600mAh = 3.25hr 03:21 < fenn> at the 800mA which i'm currently using 03:22 < bkero> NiCAD AA's are 650-800mAh 03:22 < fenn> but i dont need nicad 03:22 < bkero> If you use NiMHs you can get them 1300-2850mAh 03:23 < bkero> Good laptops will typically draw around 18W 03:23 < bkero> So if you have 2850mAh * 12V, that's 34.2 Wh 03:23 < fenn> i guess my laptop sucks then because it's using 10W? 03:23 < bkero> Are you sure it's using 10W? 03:23 < fenn> no 03:24 < fenn> that's just what acpi tells me 03:24 < bkero> 10W is pretty good 03:24 < bkero> Then theoretically a single string of the highest capacity AAs you can find would make it last for 10/34.2 hours 03:25 < fenn> uh, what? 03:25 < bkero> Your laptop is consuming 10 watts per hour 03:25 < bkero> If the battery is 34.2 Wh, that's 10/34.2 hours it'll last 03:25 < fenn> 34.2 watt*hr/10watt = 3.42hours 03:25 < bkero> Sorry, yea 03:25 < bkero> Other way around 03:26 < bkero> Hooray checking for feasability. 03:26 < bkero> 4 hours on 10 AA's isn't too bad 03:26 < bkero> My laptop is using 1487mA at 12.371mV 03:27 < bkero> 18.4 watts :/ 03:29 < bkero> 20 AA's would be a nice auxilery battery pack though. :) 03:48 < bkero> What do you think of Human completion? 04:10 < fenn> human completion? 04:11 < fenn> "Human Completion Project" can be considered as the main theme of Neon Genesis Evangelion. <-? 04:12 < bkero> There's that interpretation 04:12 < bkero> NGE was actually the human instrumentality project 04:12 < bkero> But it seems the idea is sort of the same. 04:12 < bkero> What do we do when we complete what it is we're supposed to do 04:13 < fenn> i've never seen NGE so it don't mean much. i know they diddled with genetic engineered humans some 04:13 < fenn> bkero: then logically we're "supposed" to "become complete" 04:14 < bkero> What does that entail though? 04:14 < fenn> you tell me 04:14 < bkero> I'm asking :P 04:14 < fenn> you want me to tell you what to do? 04:14 < bkero> I'm just asking what do you think that humanity will do once it's completed it's goal. 04:14 < bkero> Or once it's reached completion. 04:15 < fenn> well, that's making a lot of assumptions that i dont agree with 04:15 < fenn> 1) there is a goal 04:15 < fenn> 2) humanity is a unit 04:15 < fenn> 3) we will become complete at some future time 04:16 < bkero> It might be trascendence. 04:16 < fenn> according to the gaia hypothesis we're seeds 04:16 < fenn> but i think living on planets is stupid, so where does that leave me? 04:17 < bkero> The ISS? 04:17 < bkero> Metaphysical planes? 04:17 < fenn> heh 04:17 < bkero> Not living? 04:17 < fenn> ever heard of an o'neill cylinder? 04:18 < bkero> nope 04:18 < fenn> not living is another option, but doesn't mean much until we can define 'life' 04:18 < fenn> well, there are many different designs for space habitats, o'neill just happened to have the right sense of grand scale and aesthetics 04:19 < bkero> organic objects that grow through metabolism and reproduction :P 04:19 < fenn> nonsense 04:19 < fenn> life is DNA based cells, until further notice :) 04:21 < bkero> Life is a condition. :P 08:06 < bkero> Went to this talk this year: http://video.google.com/videoplay?docid=-7595610388533039169&hl=en 08:15 < nsh> hmmm 08:15 < nsh> i has apparantly missed a lot of teh talks 08:15 < nsh> too tired to read buffer though 08:15 < nsh> summaries? 08:17 < bkero> Used an EKG to pause space invaders when their heart rate got too high. 08:18 < nsh> biofeedback-assisted dissociation, hmmm 08:19 < bkero> It was a pretty basic demo, but it got the point across. 13:05 < elias`> kanzure: what do you use for reading RSS feeds? I find RSSOwl pretty nice, except it takes a noticeable amount of time to switch between feed items (about one second on average it seems) 13:18 < nsh> what rss feeds you subscribe to? 13:18 * nsh has never gotten around to using rss 13:24 < elias`> me? I'll get a few random samples.. 13:26 < elias`> 'Onionesque reality', xkcd, slashdot, overcoming bias, some machine learning related things, biosingularity, etc. 13:27 < elias`> I never got around to using mailing lists though, although I'm slowly trying to get into using some. 13:30 * nsh nods 13:31 * nsh has a kanzure-bot to discover and categorise pertainent and interesting informations :-) 15:40 < kanzure> elias`: akregator 15:43 < kanzure> the people I was staying with in California compulsively checked overcomingbias. 15:43 < kanzure> overcomingbias is Eliezer's filter for brilliant teenagers to work on his FAI problems 15:43 < kanzure> (he said so to me) 15:48 < nsh> meh 15:48 < nsh> Eliezer wouldn't know brilliant.. etc. 15:51 < kanzure> sensei asked me whether or not Eli was as far gone as we had feared, and I answered, "No, Eli is just fine; it's the people around him that are lost." (seriously - these guys are addicted to his adhoc morality stuff) 16:00 * bkero uses Mail.app, or some command-line rss readers. :) 17:51 < kanzure> oh, from biobarcamp 17:51 < kanzure> somebody suggested the idea of using biocatalyzed motors 17:51 < kanzure> secretion of some sort of sticky locking mechanism 17:51 < kanzure> it was just an idle, undeveloped thought of course 17:54 < kanzure> also, Joseph Jackson and Guido were suggesting the use of ATP left over from PCR to indicate whether or not the reaction worked - in situations where you can't quite run an entire gel. 17:56 < kanzure> http://heybryan.org/~bbishop/docs/David%20Yu%20Zhang%20-%20Engineering%20entropy-drive%20nreactions%20and%20networks%20catalyzed%20by%20DNA%20-%20Entropy_2007-1.pdf_%5bR4iNbb%5d.pdf 17:56 < kanzure> everybody-but@ellingtonlab.org just sent that out 17:56 < kanzure> David's apparently giving a talk later this month at the lab 17:56 < kanzure> seems to be from Winfree's lab. 19:02 < ybit> kanzure, did you ever decide to join the startup focusing on web software for futuristic scenario prediction? 19:03 < kanzure> they haven't decided to do a startup 19:08 < kanzure> haha 19:08 < kanzure> the longevity research guys want to know what my "motivation" is 19:08 < kanzure> "uh, not dying?" 19:08 < kanzure> anyway, anybody have some ideas on image processing libraries? imagemagick seems to be conversion-centered 19:09 < kanzure> I was thinking of writing my own bitmap array of sorts and just doing some calculations as to the distance between two nonwhitespace pixels or something 19:09 < kanzure> but I'm sure somebody has a better way of abstracting components of images or something .. 19:09 * kanzure leaves for a bit 19:26 < bkero> gd 19:26 < bkero> imagemagick and gd are the image processing applications for linux 19:27 < bkero> It really depends on what sort of processing you want to do. 21:57 < kanzure> bkero: I want to extract figures and tables from PDFs. 21:58 < kanzure> especially in the case where they are just images 21:58 < bkero> kanzure: pdf2ps, and you can probably grab them from the PS's easier. 21:58 < kanzure> yeah, but the whole page is a damn image 21:58 < kanzure> I need to separate the blocks by whitespace 21:59 < kanzure> or something 21:59 < bkero> oh my 21:59 < bkero> I don't know if any OCR software is gonna help you there 21:59 < bkero> Whoever turned it into the PDF must have done something strange. 22:06 < kanzure> don't need OCR 22:06 < kanzure> just need the block 22:07 < bkero> post it online? Lemme try my tools 22:08 < nsh> what's the sitch? 22:24 < kanzure> bkero: post what online? 22:24 < kanzure> any typical paper 22:24 < kanzure> :) 22:24 < kanzure> so try something from http://heybryan.org/docs/neuro/ 22:24 < kanzure> or http://heybryan.org/~bbishop/docs/ 22:24 < kanzure> or http://heybryan.org/gitweb.cgi and browse the tree for a few seconds 22:25 < bkero> lolgit 22:25 * bkero downloaded the first doc in /docs/neuro 22:30 < kanzure> bkero: Any ideas? 22:30 < kanzure> I was thinking of doing it via searching for blocks that have 20 px of white space between it and some nonwhitespace. 22:30 < bkero> It seems the full version of acrobat can extract iamges 22:30 < bkero> File->Export->Extract Images as 22:31 < kanzure> sigh 22:31 < kanzure> some PDFs have the entire page as an image though 22:31 < bkero> I haven't got much else though, sorry 22:31 < kanzure> as a baseline we just assume the entire page is PNG or JPEG or something 22:31 < kanzure> and if it isn't, we just convert it into it via pdf2ps and then some 'convert' line or something 22:31 < bkero> Then you are going to have to do some image analysis, and I've never done that before. 22:32 < kanzure> Hm. 22:32 < kanzure> any libraries? 22:33 < kanzure> or any search queries, rather? I keep running into imagemagick :) 22:33 < bkero> gd 22:34 < kanzure> sure, I remember using gd to construct images in php 22:34 < kanzure> back in the day. 22:34 < bkero> Indeed 22:40 < nsh> what you trying to do? 22:42 < bkero> Extract graphics from PDF files 22:43 < kanzure> actually 22:43 < kanzure> the whole page is assumed to be a graphic 22:44 < kanzure> so just "chunks" of the file that are clearly not connected 22:44 < kanzure> i.e. 20 px separation 22:48 < kanzure> I guess I can just go use the 'fill' features or something 22:48 < kanzure> from paintbucket 22:48 < bkero> Sounds like huag hack 22:48 < kanzure> I just need to figure out a way to isolate sections of images that are surrounded by a certain number of a certain color of pixels 22:48 < kanzure> yep 22:56 < kanzure> grr, nature is still being a whore 22:56 < kanzure> Can anybody tell me how long it takes to get http://www.nature.com//nature/journal/v206/n4987/pdf/206865a0.pdf and then http://www.nature.com//nature/journal/v206/n4987/pdf/206874d0.pdf ? 22:57 < bkero> Nature's hosting sucks balls. They should be open source, then we can host them. 22:59 < kanzure> heh :) 22:59 < kanzure> so you get the same results? 23:00 < kanzure> I mean, an obviously way too long time in between the downloads? 23:00 < kanzure> Earlier it was one paper per second. 23:00 < bkero> wget is timing out 23:01 < kanzure> hahah 23:01 < kanzure> yep 23:01 < kanzure> 501 Gateway Time-out errors 23:01 < kanzure> so they've just decided to shoo us all I guess 23:02 < elias`> I received them almost instantly, although I only probably got some pages telling to log in. 23:02 < kanzure> hm 23:04 < kanzure> so then is it just me? 23:04 < kanzure> bkero ? 23:04 < bkero> nature dns round robins to 69.22.138.40 and 69.22.138.74 23:04 < bkero> Nope, wget is still tmiing out 23:04 < kanzure> nature dnses to 170.224.106.77, 74.203.241.34 and 74.203.241.10 23:04 < kanzure> so why is it different for both of us? 23:05 < bkero> Because we're coming from different places? 23:06 < elias`> Resolving www.nature.com... 213.155.158.32, 213.155.158.58 23:06 < kanzure> wtf 23:13 < kanzure> so uh 23:13 < kanzure> suggestions? 23:14 < bkero> Tell nature their shit si broken 23:14 < bkero> I'm leaving in 15 minutes to hit the fitness center here. My fatty ass is going to ride a fake bike for a while. 23:15 < kanzure> but if I call them then they might know it's me 23:15 < kanzure> I mean, the massive download happening 5 minutes after a call goes through telling them that they are broke? 23:15 < kanzure> eh 23:15 < kanzure> heh 23:15 < kanzure> I need to call Nature from a pay phone 23:15 < kanzure> bwahah 23:21 < bkero> Tell them you're mirroring it FOR SCIENCE 23:21 < kanzure> Hahah. 23:21 < kanzure> "What, our competitors?" 23:21 < kanzure> (Science Magazine) 23:22 < bkero> yea 23:25 < kanzure> I'm sort of surprised they caught me 23:25 < bkero> They probably didn't 23:26 < bkero> Their shitty server probably just broke 23:33 < kanzure> Hm. 23:33 < kanzure> I guess. 23:33 < kanzure> since it's the same for you or something 23:33 < bkero> Yup 23:33 * bkero goes to the fitness center, then home. 23:38 < kanzure> How could it be their servers? Every 2 min I'm getting a paper. That looks like rate limiting to me .. or something. 23:38 < kanzure> maybe they did this for everyone ? 23:38 < kanzure> I've never seen this sort of server behavior before. 23:44 < kanzure> odd seeing so many papers about the USSR 23:44 < kanzure> in Nature.
