ybitmaybe it'd be nice if, i dunno, it actually played on my computer (and supported my browser w/out me having to change the identification of my OS)06:02
willPow3r_what? you don't use windows??06:03
ybitthough, tbh, i still wouldn't watch it :P06:03
willPow3r_why's that?06:03
ybitother things to do06:03
ybitother things to watch :)06:03
willPow3r_a hungarian weightlifter dislocates his elbow06:04
ybitnow that i do want to see06:05
willPow3r_in high def ;)06:05
ybitkanzure, that guy's reaction is classic06:06
ybitwillPow3r_ :P06:06
willPow3r_i think he would have been less impressed had he not been on a very boring flight06:06
ybitlongturn.org (my fav strategy game just got better) 06:11
kanzureI'm doing a brief re-read of http://en.wikipedia.org/wiki/Neural_computing and it mentions 'Given a specific task to solve, and a class of functions F, learning means using a set of observations, in order to find f within the class of functions F,  which solves the task in an optimal sense.' Geeze, damn, sounds like, I dunno, a (hack of a) compiler optimizer.06:17
willPow3r_freeciv is your fav strategy game?06:22
willPow3r_i prefer parcheesi06:22
ybitwell, it's my fav strategy game that runs on this computer and is free :)06:23
willPow3r_heh06:24
ybityou prefer a board game in the digital age o_O06:25
willPow3r_call me a luddite if you will06:25
ybithehe06:25
ybiti've always thought that those who played board games in the past would prefer RTS games these days, since the strategy required can be more dynamic06:26
ybitand just as complex06:26
ybitbut i am interested in luddite now06:26
ybitGRR06:26
ybitparcheesi06:27
willPow3r_133000 google results for parcheesi06:28
ybitand only one matters: wikipedia06:29
ybit(joking)06:29
ybit..kind of06:29
willPow3r_i'm looking for an online version06:29
willPow3r_the "cultural references" section in wikipedia articles is the most useless information06:32
ybitholy crap, http://www.yofrankie.org/ looks to be one of the most polished OS games 06:32
ybit^my initial thought from glancing at the initial screenshots06:33
willPow3r_it does look good for OS06:33
ybitbut upon further examinsation, i'm not so sure. but yeah, for an OS game, it looks great06:33
willPow3r_its definitely a step in the right direction06:34
willPow3r_for os gaming06:34
willPow3r_34 euros?06:36
ybiteh?06:37
willPow3r_that game costs $5006:37
ybitit will be free i do believe06:37
ybitthe dvd is to help the foundation06:38
ybityou don't have to purchase it06:38
ybitit's like http://www.bigbuckbunny.org/06:38
ybitand elephant's dream previously before that06:39
willPow3r_interesting06:42
willPow3r_i knew blender had a game engine06:42
willPow3r_but never really fiddled with it06:43
ybiti'm not sure how it works really, haven't messed with it, but i do know they also used crystal space06:45
ybiti bet wikipedia has the scoop06:45
ybitor not06:46
willPow3r_http://www.eurekalert.org/pub_releases/2008-08/mu-mtl081408.php06:49
fennuh, water + 1.2V = hydrogen + oxygen is nothing new?07:00
fenndont you love watered down science reporting?07:01
bkerowater + electricity = hydrogen + oxygen07:19
bkeroBecause I didn't use that as a kid to make hydrogen bombs. :)07:19
willPow3r_"Whilst man has been able to split water into hydrogen and oxygen for years, we have been able to do the same thing for the first time using just sunlight, an electrical potential of 1.2 volts and the very chemical that nature has selected for this purpose,"07:40
willPow3r_the catalyst is what's important07:40
bkeroHow about we cut out the middle man and make a car that runs off of straight atp07:42
bkeroI hear plants are pretty abundant.07:44
willPow3r_bkero: sounds like you are referring to mr. fusion07:44
bkeroWhy would it need fusion?07:45
willPow3r_http://en.wikipedia.org/wiki/Flux_capacitor#Flux_capacitor07:45
bkeroBioEngine that uses ATP for fuel :)07:46
bkeroFuck internal combustion.  I did away with that a long time ago.07:46
willPow3r_so you ride a bike mostly then?07:47
bkeroElectricity07:47
bkeroI have an electric bike, and electric car.07:47
willPow3r_i hope your electricity doesn't come from a coal-fired power plant.07:48
fennbkero: plants are not very efficient.. something like 2-6% sunlight to sugar efficiency07:48
bkeroI've got 1 800 watt solar cell07:48
bkerofenn: Could that be improved by genetic engineering?07:48
fennyes07:49
bkeroI'm sure it really varies depending on the environment too07:49
bkeroA good internal combustion engine is 25% efficient. :P07:49
bkeroGood electric motors are up to 95% mechanically efficient.07:50
fennmore than that i should hope07:50
bkeroWhen you get to big brushless dc motors they're around 99%07:50
fennthe motor is only part of the system though07:50
bkeroIt really depends on the configuration too.  You can make it more efficient of a motor by advancing the brushes, but that will destroy the motor if you ever try to use it as a generator to get electricity back.  That's why a prius has 2 electric motors.07:51
fennalso must take into account losses in the drivetrain, batteries, controller, charging system, transmission lines, yadda 07:51
fennlet's not talk about the prius07:52
bkeroDrivetrain doesn't need to exist with a linear torque curve.  With properly sized wires loss is negligable.07:52
bkeroCharging systems are pretty inefficient for the first 10% and the last 8%07:52
* bkero has made full-scale electric cars before. :P07:53
fennretrofitted right?07:53
bkeroYup07:53
fennsee, that sorta takes the fun out of it07:53
bkero91 MR2 is my car07:53
bkeroWhat?  Would you rather I make it a tube frame?07:53
fennits just that cars are totally designed around their engine07:54
fennand electric motors let you get away from that mentality07:54
bkeroThey're also the cheapest turn-key solutions available.07:54
bkeroI made it when I didn't have a lot of extra funds lying around.07:54
bkero8" Advanced DC motor, 11 NiMH EV-1 batteries, 150A Zivan charger, Curtis controller07:55
bkeroI rebuilt the "engine" in half an hour without ever doing it before. :)07:55
fennhow did you get ev-1 batteries?07:56
bkeroI bought them from a guy07:56
fenni thought they shredded them all07:56
bkeroI didn't ask where he got them from--I presume they took some batteries out of some before crushing.07:57
bkeroProbably because they posed a bad environmental impact.07:57
bkero(do they take lead-acids out of regular cars before crushing?)07:57
fennyes07:57
bkeroThat would be it then.07:57
fennhow much did all that cost?07:57
bkero$800 for the motor and controller, $2500 for the batteries, $300 for the charger07:58
bkero$1500 for the transmission adapter07:58
fennouch07:58
fennjust a plate with some holes in it right?07:58
bkeroand a fucking shit ton for motor mounts, wires, per-cell charging pcbs, and the battery rack07:58
bkeroYea.  It's custom made though, and I wasn't about to machine it myself.07:59
bkeroHeh, I'm not sure that I even needed to keep the transmission.  The only 2 gears I ever use are 2nd and 3rd.08:00
bkerolinear torque curves are awesome08:01
fennsomewhere down the project list is a three wheel electric "motorcycle"08:02
bkeroEasy to do.  I did it to my bicycle for around $20008:02
fennenclosed canopy08:02
fenntwo seats, steam engine, etc08:02
fennthis would be more like a car, with a roll frame and capable of reaching highway speeds08:03
fenni dont mind riding a bicycle around town08:04
bkeroSo you want to convert a trike08:04
bkeroand put a top on it08:04
fennno, this would be scratch built08:04
bkeroJust buy a sparrow dude lol08:04
bkeroMy ex-girlfriend has one08:04
bkero3 wheels, roof, roll cage, and I've personally taken it to 85mph08:04
* fenn shudders08:04
fennwtf is that08:05
fennit looks like something from a richard scarry book08:05
bkeroThis is the guy I bought the ev1 batteries from: http://www.youtube.com/watch?v=oifK7tJfKT008:05
bkeroGet a jellybean and not a pizza butt08:05
fennhttp://www.thingamababy.com/photos/uncategorized/scarry2.jpg08:05
bkeroHeh08:06
bkeroSparrows were made by the company Corbin, which was started by a bunch of disgruntled Harley Davidson engineers.08:06
fennyeah i believe it08:07
fenn<- not a harley fan :P08:07
bkero40 mile range, 85+mph, costs around $0.11 to fill up08:08
bkerotax breaks :D08:08
bkeroand you're not sending your money to middle eastern countries08:08
fenn1350 lbs is almost as much as my CRX08:14
fennhow is that even possible?08:15
fennit must be made out of solid lead!08:15
bkero13 lead acid batteries08:16
bkeroGood big optima yellowtops08:16
fennbatteries are only 600 lbs of that08:16
fennso what's the other 750 lbs?08:17
bkerowheels, motor, controller, brake assembly, and frame08:17
bkeroThe frame is aluminum with a composite body.08:17
bkeroand your crx is slightly more than 1350. :P08:18
fenn1715 stock, and i removed some pieces :P08:18
bkero1715 stock dry08:18
bkeroTake it to a scale and I bet it's almost 2k08:19
fennmeh08:19
fennanyway, the point is that _thing_ weighs almost as much as a full size car08:19
bkeroCRX's aren't full sized cars08:20
bkeroIt weighs well under half of most full sized cars.08:20
fennbah08:20
bkeroThe only cars that I can think of around 1800 are CRXs and 1st gen GTIs.08:20
bkeroMost cars are 2800 upwards08:20
bkeroThe 91 MR2 weighs almost 3200lbs stock08:21
bkeroAround 800 of that is the engine :P08:21
bkeroInsights make really good conversions thanks to their aluminum frames and small size.08:22
fennand they're all star-trekky too08:23
bkeroI'be seen absolutely horrendous looking insight trunks filled with A123 cells and chargers08:23
fennwouldnt it make more sense to put the batteries in the engine compartment?08:29
bkeroNot when you have 100+ A123 cells08:29
fennhow many gallons is that? :)08:29
bkeroPlus it wasn't really finalized I think08:29
bkeroGallons of what?08:29
fennvolume08:30
* bkero shrugs.08:30
bkeroIt was 2 layers of insight trunk layed out08:30
bkerolaid out08:30
bkeroWhy would in the engine compartment be better?08:30
fennfor one it would keep the weight distribution more like the original08:31
fennand if the batteries explode or vent gas it's not in the passenger compartment08:31
fennand you get to keep the trunk08:31
bkeroBatteries in the trunk give it a weight distribution closer to 50/50 than the original08:32
fennis that good though?08:32
bkeroHe could just put another board on top of the 2nd layer of batteries/chargers and have a trunk again08:32
bkero50/50 weight distribution is good for cornering, but isn't going to affect fuel economy at all.08:32
bkeroMy MR2 originally had 35/65 weight distribution.  Which makes things very squirrely and fun.  It's like driving a giant styrofoam penis with lead balls08:34
fennhmm doesn't sound very fun to me08:34
bkeroOversteer doesn't sound like fun?08:35
fenni want a car to go where i point it08:35
fennhaving weight over the steer/drive wheels just seems like a good idea08:36
bkeroNot really08:37
bkeroThat just hurts braking performance and causes understeer08:37
bkeroWhich is exactly what you don't want.08:37
fennwhy does it hurt braking performance?08:37
bkeroBecause it fucks with the suspension doing weight shifts under heavy braking08:39
fennmost of the mass should be below the wheel centerline08:39
bkeroDepends on the car08:39
bkeroWith 240sx's and eclipses they're not08:40
fenn(if you are putting batteries in the engine compartment)08:40
bkeroThe reason people use 240sx's so much for drifting is because there's so much weight in the front that it's very easy to break the rear end out.08:40
fennok, i'm talking about an electric car with front wheel drive08:41
fennsorry if that wasn't clear08:41
bkeroWith electric cars you want an equal weight distribution because of spring rates.08:42
fenngod how did they manage to make the insight even heavier than a CRX08:42
bkeroBy putting electric motors and airbags and safety features in it08:42
bkeroALL new cars are heavy as shit08:42
bkeroThey're absolutely stupid.  I don't need 10 airbags to feel safe.08:42
fenni'd rather have a good CrMo roll cage08:43
bkeroRoll cages kill people in accidents. :P08:43
fennpff08:43
fenni'll take my chances with a harness + roll cage over being squished flat any day08:43
bkeroBefore converting the MR2 I raced it in SCCA Solo2.08:43
bkeroCars don't squish flat in accidents.08:44
fennyes they do08:44
bkeroThat's what crumple zones and A pillars are for.08:44
bkeroMy car has 5 firewalls. :P08:44
fennoh re: star-trekky insight, it was the s2000 speedometer i was thinking of08:49
bkerolol honda making a rwd car08:49
fennhttp://images.importtuner.com/features/0401it_15z+2001_Honda_S2000+Interior_View_Speedometer.jpg08:50
fennnot that a tachometer would be of much use..08:50
fenni'll shut up now08:50
bkeroampmeters are nice08:52
fennhttp://img.dailymail.co.uk/i/pix/2008/05_04/FlattenedCarG_850x649.jpg08:55
bkeroTotally worried about that happening in traffic08:55
bkeroDo you live in sheepfuckistan or something?08:55
fennactually a tree fell on my first CRX, wasn't quite so bad as that though08:57
bkerolol09:02
fennthis one's not so much flat as rolled up into a little ball: http://www.daylife.com/photo/0di66uY45S5Rx09:04
bkerohahaha awesome09:05
fenndid you know roll cage + harness is illegal to drive on public roads? supposedly because you'd get stuck more easily than with a seatbelt09:05
fennnevermind the whole not getting killed in the first place thing09:06
bkeroYup09:06
bkeroand because even with padding, hitting a rollcage in an accident will break your bones.09:06
fenn... that's what the harness is for?09:06
fennand you can have airbags too if you're a wingnut09:07
bkeroEven with harnesses you're still suseptable to lateral motion.09:07
* bkero had 5-point harnesses in his car09:07
bkeroVery easy to bolt to the firewall09:07
* fenn mumbles something about phased array maser powered helicopters09:11

fenngoogle reinvents the wheel for the twentieth time09:35
kanzurehttp://www.brothers-brick.com/2008/07/23/bridge-from-singularity-sky/ <-- Lego09:37
kanzurehurry for wheels09:37
* kanzure has been hearing about "wheels" a lot at the sf con he's been going to09:37
kanzurewhich is very, very wrong09:37
fennwhy is what wrong?09:40
fennguess i have to read 'singularity sky' now09:41
kanzure'wheel of _blank_' is a common fantasy saga title09:50
kanzureand there's these stupid fantasy people at a science fiction conference09:50
kanzurein a discussion about Clarke, half the people were dressed as gnomes or something09:50
kanzureor maybe they just naturally look like that.09:50
fennoh, i see09:51
fennwhy do fantasy and sf get lumped in the same category?09:51
kanzurefuck if I know09:52
kanzurethe clumping irritates me09:52
kanzuredon't get me wrong, there can be some good fantasy out there I guess09:52
kanzurebut it's not what I'm looking for when I look for science fiction09:52
kanzurealthough, I did just get a copy of 'Silicon Mage', which is a weird "Silicon Brotherhood" sort of crossover between the two .. hrm.09:52
fennwell you can have SF detective mysteries too, but that doesnt mean you have a bunch of dick tracy guys wandering around your SF convention09:53
kanzure'Nevertheless, she had to save him. Suraklin was planning to gain immortality by placing his mind in a computer that would get its power by draining the life-force from all on both worlds, dooming everyone to eternal misery and hopelessness. And only Antryg was strong enough a wizard to challenge the Dark Mage.'09:53
fennhmm "the use of self-replicating objects" is outlawed in google lively09:56
kanzureI also fetched 'Once upon a galaxy', sf fairytales09:57
kanzureor spacepirate tales or whatever the equivalent translation is09:57
* kanzure found himself using the name 'DNA pirates' to refer earlier today to people torrenting genomes.09:57
fennlol09:57
kanzureguess we call those whores09:57
kanzureor reversewhores or something09:57
kanzurehttp://nesteduniverse.net/events.html ai-related events/conferences ... somebody did their homework :)09:59
fennseems like charles stross is more about aggregating ideas from other SF authors than coming up with his own10:22
fennthat's not necessarily a bad thing, but i'd rather read about it from the original source first10:23
kanzureyep10:48
kanzureit's why I don't actually read him10:48
nshhttp://impromptu.moso.com.au/gallery.html16:28
kanzureso apparently Clarke is famous among his friends for sending "ego grams" where he just dumps everything he's been working on in his local short term memory to a paper and just sends that as his "what I've been up to" response letter. 22:49
kanzuredoesn't sound like a bad idea, coming up with these them 'egograms'.22:49
kanzureSomething I picked up on today: Revelation in a World of Science: A Comparison of Revelation in Paul Tillich’s Systematic Theology / AG Latner - MA Thesis. Graduate Theological Union, 1985 / http://en.wikipedia.org/wiki/Paul_Tillich / http://www.sff.net/people/alexis-latner/22:57
nshhrm23:00
nshwhy do you always post interesting things when i've used up all my brainpower for the day, kanzure?23:00
kanzuredon't get me wrong, my brainpower is dwindling too23:02
kanzureI really should be sleeping right now23:02
* nsh too23:02
kanzurebut I'm trying to figure out quantifications of the effectiveness of recombinational methodologies where 'recombination' is more about the recombination of forked (physical) processes (not really just on my computer).23:03
kanzureI guess it's just compiler optimization still where the most effective methods will be the most elegant / 'efficient' etc. but that doesn't tell you anything about how to actually write the code necessary for23:04
kanzurehrm, I haven't filled you guys in on the context23:04
* kanzure scurries off to eat some dinner23:04
nshmmm, monadic23:05
kanzure?23:05
nshmonads23:06
nshnon-sequencial code wrapping23:06
kanzuresort of23:23
kanzureso here's what I'm talking about23:23
kanzurehrm, this is hard23:24
fennanything is stated simply enough when you design the entire language around it23:31
nshfenn++23:34
kanzureI've been able to make skdb do the eukaryote story, at least in my head, but I haven't the guarantee that you will be able to immediately productively go along various paths of recombination with various 'weird stuff you sniff up' /unless/ you have a ridiculous amount of time to sit around and work on esoteric interfaces23:34
kanzureor, put another way,23:35
nshyes pls do23:35
kanzuresuppose you've grounded your social context with some backup clone generators and artificial wombs or womanly wombs and such, and you have your little clones running around getting stuffs for you, you don't have the guarantee that they will necessarily care .. I'm not looking for a way to use an iron fist here, just a way to .. not waste time.23:35
kanzureby 'care' I mean contribute back to send you patches and new stuff to 'recombine with' just as the cell took with it the mitochondria etc. and other viruses etc.23:36
fenni thought you already had decided that biological systems were hard to program23:36
kanzureI have a way that 'kids' could send updates to their parent-node in a patch submission scheme, perhaps built off of the idea of neurotech + working with neuroplasticity rules + the neuronal basis of instincts (yeah, weird, I know -- but no 'meme=perception' transfer stuff here, I don't need that (but I'd be glad to get it of course))23:38
kanzureparenting with the iron fist of this-is-what-you-shall-become is incorrect and generally fails and is not worth lying to yourself about the construction of new brains to do your bidding23:39
kanzureand you're right that programming of these sub-brain thingies would be ridiculously hard :)23:40
kanzureI mean, you could wire them up to Skinner boxes and make them all go through the same exact stimulatory routines through development, but it's still probabilistic and I refuse to leave things up to 'chance' (whatever the hell that is)23:40
kanzurenow, I was figuring that if neural networks are really just a sneaky way of doing code optimization, then you could theoretically select for the "lesser of the two evils" and just support either MEA + neural tissue pods that do interesting stuff and toss the rest, but that doesn't seem to fit23:41
kanzureI know this is rather dense and it's not really supposed to make sense yet since I don't have it completely hashed out23:42
fennhash away23:43
fennit all sounds familiar to me i guess23:44
* nsh will read tomorrow23:44
nshmust sleep brain now23:45
kanzureI wonder if calling it linkbacks in meiosis is legitimate23:45
kanzurejust sprang to mind, it might not be the same thing23:45
kanzureby 'linkback' I mean 'the patch is, in fact, sent back'23:46
kanzureI think that I need to reconsider how much information processing a pile of neurons in goo is going to be doing ... suppose the brainfarms, or the simulations even, of networks - I don't actually have evidence that your simulation of a small group of neurons for feature recognition on news articles (or something) is going to fail to respond because it wants to do something else. :p23:50
