brownies | there ought to be a rule of thumb here | 00:02 |
---|---|---|
brownies | if you're not smart enough to acquire nootropics on your own, you shouldn't be experimenting with nootropics | 00:03 |
Lemminkainen_ | aw come now brownies | 00:04 |
Lemminkainen_ | tain't about not being smart enough here, it's about appealing to others' experience first | 00:04 |
Lemminkainen_ | if nmz787 were to be all "don't even ask that brownies moob, they're shady as fuck and will give you salt pills", I'd appreciate that metis | 00:05 |
nmz787 | kanzure: http://imgur.com/r/funny/JG5dA | 00:06 |
nmz787 | brownies: but what if a dose of nootropics enabled you to become smart enough to acquire more nootropics??? sortof starting a chain reaction? | 00:07 |
nmz787 | but i kinda agree | 00:08 |
nmz787 | what | 00:08 |
nmz787 | what's NAC | 00:08 |
Lemminkainen_ | nmz787: N-acetyl cystein | 00:16 |
Lemminkainen_ | *cysteine | 00:16 |

jrayhawk | a GAPS or ancestral lifestyle template always help, too | 10:58 |
nmz787 | GAPS? | 10:58 |
jrayhawk | GAPS is a good ultra-conservative medical dietary intervention | 10:59 |
jrayhawk | it's not very pleasant long-term, though | 10:59 |
Mokbortolan_ | Gastro - and Psychology Something | 11:00 |
jrayhawk | It's designed as a gut-healing protocol, which winds up having profound effects on metabolic, autoimmune, and psychological problems | 11:01 |
kanzure | can he just have his prostate removed? | 11:04 |
jrayhawk | cambell-mcbride is a lot more paranoid about lesser known food intolerances, like FODMAPs and insoluable fiber, than the usual ancestral dieting folks are | 11:04 |
jrayhawk | she's been good at pushing bone broth, though, which is cool | 11:05 |
nmz787 | kanzure: i guess its spread outside there | 11:05 |
jrayhawk | oh | 11:05 |
jrayhawk | usually when somebody says 'prostate cancer' they mean 'mostly innocuous mass that will probably take twenty years to actually do anything effectual' | 11:07 |

nmz787 | Debut of the first practical “artificial leaf” | 13:17 |
nmz787 | The first artificial leaf was developed more than a decade ago by John Turner of the U.S. National Renewable Energy Laboratory in Boulder, Colorado. Although highly efficient at carrying out photosynthesis, Turner’s device was impractical for wider use, as it was composed of rare, expensive metals and was highly unstable — with a lifespan of barely one day.Nocera’s new leaf overcomes these problems. It is made of inexpensive mate | 13:18 |
nmz787 | The key to this breakthrough is Nocera’s recent discovery of several powerful new, inexpensive catalysts, made of nickel and cobalt, that are capable of efficiently splitting water into its two components, hydrogen and oxygen, under simple conditions. Right now, Nocera’s leaf is about 10 times more efficient at carrying out photosynthesis than a natural leaf. However, he is optimistic that he can boost the efficiency of the artific | 13:18 |
ThomasEgi | 10 times more efficient than natural photosynthesis eh?.. | 13:19 |
nmz787 | http://nocera.mit.edu/Home | 13:19 |
ThomasEgi | i am pretty sure that natural photosynthesis is about 30% or so | 13:20 |
nmz787 | if it comes to market, hell yea! | 13:20 |
nmz787 | I thought natural was 8% | 13:20 |
nmz787 | or so | 13:20 |
ThomasEgi | under natural daylight about 20, accordnig to wikipedia | 13:21 |
nmz787 | http://en.wikipedia.org/wiki/Photosynthetic_efficiency | 13:21 |
ThomasEgi | and.. doing something 10 times more efficient than millions of years worth of evolution... sorta rings my bullshit-alert-bell | 13:21 |
nmz787 | i'm seeing 3-6% | 13:21 |
ThomasEgi | if you count in photorespiration | 13:22 |
kanzure | ThomasEgi: wait, what? there's no reason nature would have found a step-wise change like that, ever | 13:23 |
kanzure | or a natural route to an order-of-magnitude improvement | 13:23 |
ThomasEgi | i just say that i'd triple-doubt that 10x more efficiency information | 13:24 |
ThomasEgi | and ask how the the number came up. | 13:24 |
ThomasEgi | because it smells like someone want's to advertise his research and picks semi-related numbers to fabricate a 1000% efficiency gain | 13:25 |
nmz787 | this is a good overview on artificial photosynthesis from Materials Research Society in 2008 (I have this in print) | 13:25 |

nmz787 | Engineered and Artificial Photosynthesis: Human Ingenuity Enters the Game | 13:25 |
nmz787 | "The best single-threshold photovoltaic devices have ECEs that approach the Shockley–Quiesser limit of about 30%, which was calculated taking all of the above considerations into account. In contrast, although the initial steps of plant and bacterial photosynthesis often have very high quantum yields, the ECE of natural photosynthesis is relatively low (maximally about 6% but usually observed to be <0.8%)." | 13:27 |

ThomasEgi | chris_99, take a small bundle of pubes, count those and do modulo 10 to get a 0-9 digit | 14:36 |
chris_99 | that's one of the comments basically | 14:36 |
chris_99 | i liked this one too 'Bash your head against the wall and count the stars.' | 14:37 |
Mokstar | sounds like it'd be easier to toss hairs into the air and then count the intersections when they land on each other | 14:40 |
Mokstar | of course, that'd leave you with a distinct lack of 0's | 14:40 |
Mokstar | but you'd get fluid dynamics in the mix | 14:40 |

kanzure | bloop bleep. | 16:15 |
kanzure | "The long-held serotonin hypothesis has proven to be completely baseless and there is no good evidence that depression has a neurochemical etiology" | 16:17 |
kanzure | neat, i'd love a citation on that last part | 16:17 |
jrayhawk | http://evolutionarypsychiatry.blogspot.com/2011/11/depression-beyond-chemical-imbalance.html is a decent read, though also needs more citations | 16:26 |
ParahSailin_ | kanzure, o snap | 16:27 |
kanzure | i like how everyone thinks brain stuff is simple "dopamine/serotonin levels", it's really cute :) | 16:27 |
kanzure | so anything that proves otherwise is worth keeping around | 16:28 |
ParahSailin_ | md's are mostly hacks | 16:29 |
jrayhawk | http://evolutionarypsychiatry.blogspot.com/2011/12/beyond-chemical-imbalance-part-2.html ah, this one has a nice big citation | 16:31 |
brownies | there's no good evidence that depression has a neurochemical basis? o.O | 16:37 |
kanzure | well it's not like we are monitoring the neurochemical output in depressed people at every neuron | 16:37 |
kanzure | usually these people have objections to splitting their heads open, it's realy annoying | 16:37 |
kanzure | *really | 16:38 |
jrayhawk | it's an argument about semantics, really. are b-vitamins and carnatine neurochemicals? | 16:39 |
jrayhawk | and i guess about framing etiology | 16:40 |
-!- chris_99 [~chris_99@unaffiliated/chris-99/x-3062929] has quit [Quit: Leaving] | 16:40 | |
kanzure | i suppose the original author of that quote should have said "no good evidence that depression is directly caused by serotonin levels" | 16:41 |
kanzure | but that would be redundant | 16:42 |
jrayhawk | that's not entirely true | 16:42 |
jrayhawk | monoamine manipulation actually does work in a lot of cases | 16:43 |
jrayhawk | but 'etiology' is the key word he uses | 16:43 |
jrayhawk | disease management is not the same as health care | 16:46 |
jrayhawk | oh, his proposal is medicre. that's too bad. | 16:49 |
jrayhawk | 'It is entirely possible that the idea of depression is itself a cause of depression, in much the same way that the western presentation anorexia nervosa has been imported into Chinese culture and is slowly replacing the far more common indigenous eating disorder, which presented as idiopathic digestive problems rather than a psychological aversion to food based in body image.' | 16:50 |
jrayhawk | ha ha that guy has no idea how tightly coupled the intestine and the brain are | 16:50 |
kanzure | i didn't quote his other stuff because it was stupid | 16:51 |
jrayhawk | yeah, good call | 16:51 |
jrayhawk | 'Anecdote is not the singular of data' uh... | 16:54 |
brownies | yeah, what an idiot. everyone knows it's anecdatum. | 16:55 |
brownies | jrayhawk: fair point about etiology. | 16:55 |
jrayhawk | the plural of anecdote must clearly be datums | 16:55 |

ParahSailin_ | i've talked to homeless people that arcane | 20:52 |
ParahSailin_ | they never got any story in the newspaper for themselves though | 20:52 |
brownies | kanzure: skimming... nice idea... very meta. | 20:56 |
brownies | kanzure: the question is whether he can invent an idea-generating tool that can generate the idea for itself | 20:56 |
skorket | so, algorithmic idea generation? | 20:59 |
nmz787 | seemed more like a simple matrix multiply to me | 21:02 |

nmz787 | what's a PhD in Rhetoric anyway? | 21:06 |

nmz787 | beep | 22:09 |
skorket | how are things nmz787? | 22:33 |
nmz787 | trying to help my gf with her thesis | 22:41 |
nmz787 | which is image classification via artificial neural networks | 22:42 |
nmz787 | I got my power supply, but not the diode yet... the seller sent it with delivery confirmation, and I don't see the postman (I guess he doesn't knock loud enough?) so I still dont have the laser | 22:42 |
nmz787 | so I think this is how ANNs work: basically you need to feed input to the neurons, and either ask a question (if statement) and get a binary output (yes no, 0 1) based on the some initially chosen threshold value (weight of neuron?), or is something like input X * weight-of-neuron then square rooting that and feeding it into the next layer | 22:43 |
nmz787 | this has some example input data for an ANN with 114 input nodes and 1 or 3 outputs http://www.powershow.com/view/114301-NDg1N/Glaucoma_Detection_Using_An_Artificial_Neural_Network_flash_ppt_presentation | 22:45 |
skorket | One model that I studied, and I think it was pretty common, was that neurons were connected via edges. Each edge had a weight to it. Output from one neuron was multiplied by the weight | 22:51 |
skorket | output from the previous layer multiplied by weight and summed. | 22:51 |
skorket | Either fire the neuron if it crosses the threshold or use some sigmoid function to approximate a step function | 22:51 |
skorket | nothing special, just partition the higher dimensional space into two | 22:51 |
nmz787 | i'm looking to do image noise classification. i think i want to diff adjacent pixels, and have the diff be the input to a single neuron. or diff adjacent pixels in a kernel, and have the kernel RMS value feed into a neuron | 22:52 |
skorket | what's the end goal? | 22:52 |
nmz787 | pattern of a camera | 22:53 |
nmz787 | also these would be dark images | 22:53 |
nmz787 | i.e. the sensor was covered from light when recorded | 22:54 |
nmz787 | (dark for training, then compare with real life 'test' image) | 22:55 |
nmz787 | since the training diffs will be pretty small, the test image will probably only give a positive result in areas of similar or low illumination. So I think the bigger the image, the better | 22:56 |
