@fenn | kanzure: tDCS is safe, cheap, demonstrated to be beneficial. ultrasound is expensive/unobtainable, carries significant danger of accidentally frying parts of your brain, and nobody knows how to use it for good (yet). given these, how can you recommend ultrasound over tDCS? | 12:46 |
@kanzure | nobody has demonstrated a practical benefit of tdcs except new age bullshit | 12:47 |
@fenn | pretty sure they demonstrated increased learning rates | 12:47 |
@kanzure | whereas transcranial ultrasound has caused potentials in the motor cortex to move limbs and even whole whiskers | 12:47 |
@fenn | i can already move my limbs and whiskers | 12:47 |
@kanzure | the point of limb movement is that it's extremely obvious that the device is working | 12:48 |
@kanzure | (or not working) | 12:48 |
@fenn | if i wanted to induce a seizure, there are much safer methods | 12:48 |

@kanzure | ugh | 13:03 |
@fenn | go learn to tapdance and tell us if it's faster than average after being tazed | 13:03 |
@kanzure | today we've learned that delinquentme doesn't know how to handle relationships or girls | 13:04 |
@fenn | no, we already knew he's a spazz | 13:04 |
delinquentme | hahahaha | 13:04 |
delinquentme | YESSSSSSSS | 13:04 |
ThomasEgi | my guess upon observing this conversation is: mankind tries to come up with drugs to get the same good feelings like being in a relationship. but without the breakup-pain. | 13:04 |
@kanzure | uh.. no. | 13:05 |
@nmz787 | delinquentme: playing in traffic might be more edgy now | 13:05 |
@fenn | dodging cars is the new rock climbing? | 13:05 |
@nmz787 | though that buzz is probably associated with evolving to do serial monogamy | 13:06 |
ThomasEgi | bouldering => lorrying? | 13:06 |
@nmz787 | parkour | 13:06 |
@fenn | park whore? | 13:06 |
@kanzure | i don't really like it when delinquentme shows up to jizz all over everything in here | 13:06 |
@kanzure | but that's practically all he does | 13:06 |
delinquentme | ThomasEgi, nah I think the drugs we're after are for effects we want | 13:07 |
delinquentme | its not advantageous to be tweaking shaky and fight / flight when I'm trying to focus | 13:07 |
@fenn | hmm. are there any OTC beta blockers? propanolol isnt exactly available at the corner store | 13:08 |
@fenn | eucommia (chinese rubber tree) bark, one of the fifty fundamental herbs of TCM | 13:13 |

@nmz787 | fenn no input on S curve vs half S curve turbulence? | 14:11 |
@nmz787 | kanzure: facebook ping | 14:19 |
@kanzure | shouldn't you be doing dna things | 14:19 |
@kanzure | why facebook ping | 14:19 |
@fenn | larger radius turns have less turbulence.. however the air will take a path of least momentum change so D shaped cross sections are best. are you seriously modeling your car's exhaust in comsol? do something useful | 14:19 |
@fenn | fwiw the second one looks higher quality | 14:20 |
@nmz787 | they;re made by same manufacturer, but the second is a different design | 14:21 |
@nmz787 | bith mandrel bent | 14:21 |
@nmz787 | both | 14:21 |
@nmz787 | this problem /does/ seem easier than microfluidics shit | 14:21 |
@nmz787 | since I only care about the turbulence | 14:21 |
@fenn | it's pretty much a solved problem | 14:21 |
@nmz787 | though I guess i could add heat transfer | 14:22 |
@nmz787 | but I don't have any comsol experience | 14:22 |
@nmz787 | i watched an hour lecture on youtube | 14:22 |
@kanzure | i don't understand the facebook thing | 14:22 |
@kanzure | where am i supposed to be looking | 14:22 |
@nmz787 | kanzure: a soul needs help with getting a job, doesn't know how to code | 14:22 |
@nmz787 | i mentioned you | 14:22 |
@nmz787 | should be in the earth icon | 14:23 |
@kanzure | it didn't seem to ping me | 14:23 |
@nmz787 | huh | 14:23 |
@nmz787 | maybe you're signed into some pseudonomous account? | 14:23 |
@kanzure | i am signed into facebook.com/kanzure | 14:23 |
@fenn | btw nmz787 the length of the pipe changes the resonance frequency, which affects at what speed you get the best efficiency/power | 14:24 |
@fenn | most older cars are tuned for 55 mph which is sort of slow these days | 14:24 |
@nmz787 | i think not in this case fenn since this is post-turbo | 14:25 |
@nmz787 | heard it chops up that | 14:25 |
@fenn | oh right, TDI, duh | 14:25 |
@nmz787 | seems by upsizing at most i'll achieve lower exhaust temps and thus increase lifespan of turbo | 14:26 |
@nmz787 | since i'm not adding turbo upgrades or bigger injectors or a chip tune | 14:26 |
@fenn | shh dont tell ybit | 14:29 |
@fenn | i lost interest in piston engines when i learned about turbonique and realized the whole industry is fake | 14:30 |
@bkero | fenn: How about six strokes? | 14:31 |
@fenn | i dont even know what that is or why it would matter | 14:31 |
@fenn | heat scavenging? | 14:31 |
@bkero | efficiency | 14:31 |
@fenn | yeah, diesel is interesting from an efficiency standpoint, but that's not what most car hobbyists are trying to do | 14:32 |
@nmz787 | atkinson cycle is close | 14:33 |
@nmz787 | but you can't double the hp and torque in a prius like you can with this car | 14:33 |
@fenn | or maybe this is something like an internal combustion stirling engine | 14:34 |
@nmz787 | (with aforementioned mods) | 14:34 |
@nmz787 | not including a new clutch and flywheel to take the power | 14:34 |
@nmz787 | which i just changed 2 years ago | 14:34 |
@fenn | you'll still get spanked by any stock motorcycle | 14:36 |

@nmz787 | yeaa but i do like the cage around me in the car | 14:41 |
@fenn | the way i see it, you're never going to beat the efficiency of a nuclear/solar/wind powered electric car, and you're never going to beat the power density of rockets (until we get artificial gravity generators) so piston engines are somewhere in the middle | 14:45 |
@fenn | why not just put rockets on your electric car, with a recuperative diesel cruise engine | 14:45 |
@nmz787 | >| | 14:47 |
gradstudentbot | I'll be at the microscope. | 14:47 |
@fenn | the only sticking point is whether you need to drag the cruise engine around with you all the time, or you're able to plan on cross-country journeys beforehand | 14:47 |
@fenn | re tDCS: | 14:50 |
@fenn | Applying the electrodes to the prefrontal cortex can improve learning and increase your working memory. | 14:50 |
@fenn | Applying them to the motor cortex can raise your threshold for pain and make you more adept with your nondominant hand. | 14:50 |
@fenn | Position them above the posterior portion of the left perisylvian area (in right-handed people) and they can facilitate language acquisition. | 14:50 |
@fenn | Stimulation of the parietal cortex can improve numerical reasoning. | 14:50 |
@kanzure | i don't think those are easily tested at all | 14:51 |
@kanzure | numerical reasoning could mean anything | 14:51 |
@kanzure | threshold for pain is not something i'm interested in testing | 14:52 |
@fenn | name something beneficial that is easy to measure | 14:52 |
@kanzure | it doesn't have to be beneficial. you just need something equivalent to an "on" light that works. | 14:52 |
@kanzure | s/light/indicator | 14:52 |
@fenn | please elaborate | 14:52 |
@kanzure | beneficial stuff comes later | 14:53 |
@fenn | oh, i see, like the blinking LED hello world | 14:53 |
@fenn | but for brain hacking | 14:53 |
@kanzure | oscilloscope can check if it's "working" but that doesn't tell you if it is working.. | 14:53 |
@fenn | how about phosphenes, would that be objective enough? | 14:55 |
@kanzure | yes, that would be fine | 14:56 |
@fenn | well, that's an observed "side effect" | 14:56 |
@kanzure | in other words.. not targetable? | 14:57 |
@fenn | oh, "if the electrode is placed near the eye" so it's not proof of a change in brain activity | 14:57 |
@kanzure | without targeting i'm not sure what you expect to be able to do with a tdcs cap once you see a phosphene | 14:57 |
@kanzure | haha what. i'm p. sure i've heard of other tdcs/phosphene things before that were not that. | 14:58 |
@fenn | okay say you put your electrode on V1 and see phosphenes, does that change your opinion of tDCS? | 14:59 |
@kanzure | no, i was already aware of phosphene reports | 14:59 |
@fenn | then you're just willfully ignoring what you already know | 15:00 |
@kanzure | you were the one asking for something to measure | 15:00 |
@kanzure | so let's flip this around for a sec | 15:00 |
@kanzure | with tdcs your plan is to get a bunch of electrodes, get some skull coordinate system, probably stereotactic something system | 15:00 |
@kanzure | then record where you put the electrodes and what current you're using | 15:00 |
@kanzure | and then write down what effects you experience? | 15:00 |
@kanzure | or are you planning on targeting specific cubic volumes of bran matter somehow | 15:01 |
@kanzure | or what's the plan here | 15:01 |
@fenn | no, most effects would be difficult to notice | 15:01 |
@fenn | if my language acquisition rate went up, i have no clue how that would affect my subjective experience | 15:01 |
@kanzure | what was that story about a tms setup that was able to switch someone's auditory-verbal understanding on/off | 15:02 |
@kanzure | it was something. it wasn't vision going on/off.. | 15:02 |
@fenn | oh totally, but TMS works by inhibiting areas | 15:02 |
@kanzure | different areas of the brain work differently based on what you mean by inhibiting.. for instance, thinking correlates to inhibition. | 15:03 |
@kanzure | (positively, in the upward direction) | 15:03 |
@nmz787 | kanzure: i told my friend to come in here on webchat | 15:03 |
@kanzure | okay i will be extra mean | 15:03 |
@kanzure | oh you mean your jobless friend | 15:03 |
@fenn | erm. there's a difference between increasing activity in an area, and overwhelming normal activity with noise | 15:03 |
@kanzure | what did you want me to do? | 15:03 |
@fenn | tell him to send a resume in .doc format with embedded malware | 15:04 |
@nmz787 | he needs to realize he's not stupid and can learn to make good money coding | 15:05 |
@nmz787 | he had autism/aspergers supposedly when we were kids | 15:05 |
@fenn | uh, autism doesn't magically go away when you grow up | 15:05 |
@nmz787 | and i think his mom was overprotective or something, and ruined his confidence | 15:05 |
@nmz787 | fenn: shh | 15:05 |

@kanzure | ask nmz787. he did lots of epigenetic methylation stuff i think. | 15:20 |

@heath | h3k27me3 | 15:21 |
@heath | got it | 15:21 |
@fenn | heath: what is an epigenetic mark? | 15:22 |
@heath | proteins which encode instructions for dna to be compacted further or read | 15:22 |

@fenn | what the hell, youtube-dl doesn't work on ted videos | 15:25 |
@kanzure | youtube-dl --upgrade | 15:25 |
@fenn | hm weird it works if i delete the &list= part of the url | 15:26 |
@kanzure | fenn: so, the only other complaint i have about the proposed method is that you can't really use information found in papers to inform your electrode positioning choices, since targeting isn't really doable yet. there was one paper that did some targetting.. maybe i should go review that. | 15:26 |
@fenn | you have to change your paradigm of "targeting" | 15:26 |
@fenn | obviously you're never going to turn on a single cell, that isn't the point | 15:27 |
@kanzure | i don't mean stereotactic maps are impossible, but rather that given a name of a mm^3 region of brain goo, you can't do much with that. | 15:27 |
@fenn | the whole idea is you're upregulating the activity of a broad area | 15:27 |
@kanzure | i don't think you need a single cell, definitely | 15:27 |
@fenn | believe it or not different swaths of brain do different things | 15:27 |
@kanzure | yes, well, hitting 30% of the brain in a single blast isn't very useful | 15:27 |
@fenn | i disagree | 15:28 |
@kanzure | wh? | 15:28 |
@kanzure | *why? | 15:28 |
@fenn | increasing activity in 30% of the brain is useful | 15:28 |
@fenn | see above list of benefits | 15:28 |
@fenn | and it seems to be slightly more accurate than that | 15:28 |
@kanzure | yeah, i pulled the number out of my ass, i don't actually know which number i would be happy about | 15:29 |
@fenn | fMRI may not be as good as fluorescent calcium reporters in zebrafish, but it works on live humans and doesn't do any damage | 15:30 |
@kanzure | i think it was http://diyhpl.us/~bryan/papers2/neuro/tdcs/A%20novel%20array-type%20transcranial%20direct%20current%20stimulation%20(tDCS)%20system%20for%20accurate%20focusing%20on%20targeted%20brain%20areas%20-%202011.pdf | 15:30 |
@fenn | just because the tools we have aren't perfect doesn't mean we should never use them | 15:30 |
* fenn mumbles about triple negatives | 15:30 | |
@fenn | yeah i don't believe that paper | 15:31 |
@kanzure | what do you not believe about it? | 15:31 |
@fenn | it treats the brain an an isotropic medium, but tensor imaging shows that's obviously not the case, and further that the structure is different between individuals | 15:32 |
@kanzure | the structure is different but they were using the scan of a single brain and i think their study was w.r.t that model | 15:33 |
@kanzure | so that point isn't valid. i think it's okay if we demand everyone gets a brain scan before stimulating it. | 15:33 |
gradstudentbot | Did you order the carbon nanotubes yet? | 15:33 |
@fenn | also, even with their bogus assumptions, the specificity still sucks | 15:33 |
gradstudentbot | If I was your endoplasmic reticulum, would you want me smooth or would you want me rough? | 15:33 |
@kanzure | i agree that different regions of the brain are more conductive than others, and you can probably measure that under fMRI.. | 15:34 |
@fenn | pretty sure they just scanned for geometry. see section II-A "since the inhomogeneous electrical conductivity distribution of a | 15:35 |
@fenn | fucking pdfs | 15:35 |
@fenn | human head cannot be estimated accurately even with the | 15:35 |
@fenn | currently best imaging modalities, we used widely accepted | 15:35 |
@fenn | effective electrical conductivity values of head structures. | 15:35 |
@kanzure | that probably means skin/scalp/bone stuff and not the brain matter | 15:36 |
@fenn | yes, it does | 15:36 |
@fenn | but it shows they didnt even try to measure the brain conductivity itself, or weren't aware of it | 15:36 |
@kanzure | i'm sure someone has tested the electrical conductivity between regions of the brain | 15:36 |
@kanzure | and if they haven't then we should get the backyard brains guys to do that with some rabbit/cat brain or something | 15:36 |
@kanzure | or rhesus brain. | 15:36 |
@kanzure | i bet you could make an automatic test apparatus that rotates the brain and changes probe insertion points or something | 15:37 |
@fenn | and anyway, even if you do have a perfect model of a bowl of salty jello, you're never going to be able to focus DC on a single point that isn't close to the surface | 15:37 |
@fenn | it's just not in the equations | 15:38 |
@nmz787 | the only epigenetics i've followed is the starving while pregnant influencing insulin regulation in next generation | 15:39 |
@nmz787 | figure it might impact me since my mom was bulemic during my carriage | 15:39 |
@fenn | cool | 15:40 |
@fenn | so you are like an X-men mutant or something? | 15:40 |

@fenn | wah, reading is too hard | 15:43 |
@fenn | someone get to work on artificial genetic memory | 15:44 |
@fenn | what's the epigenetic differential for "expert neuroscientist" | 15:44 |
@kanzure | i regret naming files with random hashes | 15:48 |
@kanzure | why the fuck did you guys let me get away with that | 15:48 |
@fenn | didn't know they were random until too late | 15:49 |
@fenn | why didnt you at least use md5? | 15:49 |

@kanzure | fenn: the other complicating factor- besides just randomly testing different electrode configuration- is that different stimulation patterns are different, and then you have to go through the whole test battery again. | 15:54 |
@kanzure | fenn: this is partly why i think targeting helps with informed decisions about what stimulation to try | 15:54 |
@kanzure | superkuh: how would you pick what to stimulate? | 15:54 |
@fenn | "different stimulation patterns" meaning multiple areas at the same time? | 15:55 |
@kanzure | i meant duration/timing | 15:55 |
@fenn | or do you mean stuff like tACS | 15:55 |
@kanzure | wave shape stuff | 15:55 |
@kanzure | erm, i mean, timing function | 15:55 |
@fenn | sure, same thing more or less | 15:55 |
@kanzure | yeah, in the case of tACS it would be wave shape | 15:55 |
@fenn | let's make up a new acronym, tPCS | 15:56 |
@fenn | tMCS | 15:56 |
@fenn | no that's too close to TMS | 15:56 |
gradstudentbot | Are there any of those hamster ovaries left? | 15:56 |
@kanzure | acronyms are dumb. transcranial dc is really obvious. | 15:56 |
@fenn | any electrical engineer knows there's a world of difference between steady-state DC and some kind of pulse train or waveform with a positive bias | 15:57 |
@fenn | but they're both technically "DC" so it's ambiguous | 15:57 |
@fenn | if we're going to try to reduce the parameter space, we need to use some theory. in (ahem) "on intelligence" the idea that all cortical cells are pretty much the same means we can search for the optimal stimulation waveform and use it on any area | 15:59 |
@fenn | if you're targeting non-cortex then you have to re-do the waveform tests.. | 16:00 |
@kanzure | there are different regions of the brain that operate very distinctly. some are sparse ensemble encoders that work via inhibitory neurons. others are just the opposite.. i don't see your point. | 16:00 |
@fenn | i didn't say the whole brain was the same, just the cortex | 16:00 |
@kanzure | there are many cortexes yo | 16:00 |
@fenn | bah | 16:01 |
@fenn | anyway the number of permutations and the testing time are too big and sloppy to feasibly brute force | 16:02 |
@kanzure | somatosensory cortex, primary motor cortex, auditory cortex, blah blah blah | 16:02 |
@kanzure | yes, i agree | 16:02 |
@fenn | anannie: did you decide on a project yet? you wouldn't want to end up like me | 16:03 |
anannie | fenn: I'm building a hexapod this week | 16:03 |
anannie | I've been busy with work, so the building bit hasn't happened | 16:04 |
anannie | but I'm gonna build it | 16:04 |
@fenn | did you know lego used to have pneumatic components? | 16:04 |
poppingtonic | has anyone considered studying the relationship between isotropic temperature (through IR emission) regions in the entire nervous system and sensations? | 16:04 |
anannie | fenn: It still does | 16:04 |
anannie | fenn: I used to have those | 16:05 |
@fenn | ouch. well if you can't afford $10 per cylinder, you can use syringes | 16:06 |
anannie | fenn: Syringes have issues with the gasket breaking down after regular use... | 16:07 |
@kanzure | fenn: using the same waveform on any region of the brain isn't going to work. can you think of something else? | 16:09 |
@fenn | poppingtonic: it has more to do with blood flow than temperature, but https://en.wikipedia.org/wiki/FNIR | 16:09 |
@kanzure | there are many studies about different types of neurons and how they behave to different stimulation (while in a dish) | 16:09 |
@kanzure | so if there's some way that information could be used to make informed decisions somewhere else, that would be useful | 16:09 |
@fenn | but cortex is mostly pyramidal neurons | 16:10 |
anannie | poppingtonic: Why did you specify isotropic, btw? | 16:10 |
@fenn | so who cares what's in the blob of the day | 16:10 |
@fenn | isotropic usually means the blackbody is in temperature equilibrium (i think) | 16:11 |
@fenn | or maybe there are crystals that emit directionally? | 16:13 |
@kanzure | what would the plan be for the problem space anyway? this is a very combinatorial problem. more than there are potential test subjects. | 16:15 |
poppingtonic | anannie: Because of how information travels between neurons. | 16:15 |
anannie | poppingtonic: That's a gradient right? | 16:15 |
@fenn | kanzure: so you're assuming tDCS/tACS has a permanent effect | 16:16 |
@kanzure | no | 16:16 |
poppingtonic | anannie: yeah. My explanation is quite lengthy, I'll have to put it up on refheap. | 16:17 |
@fenn | "A body in the cavity is at thermal equilibrium with the thermal isotropic radiation inside the cavity temperature T of its surrounding." mumble grumble | 16:17 |
@kanzure | i can imagine effects that last for a few seconds during stimulation, that last for a few minutes after stimulation, that last a few hours after stimulation, some that are permanent, others that occur only after 20 minutes of stimulation and only then for 15 seconds, etc. | 16:17 |
@kanzure | this is why i think we need to be able to model parts of the brain and then predict what stimulation will do, or ways to break its normal operation | 16:18 |
@kanzure | and then repeat that in a physical test | 16:18 |
@fenn | i bet most of the effects are of duration 1-2 days and don't appear for several hours | 16:18 |
@fenn | since it seems to be based on genetic transcription (for tDCS at least, dunno about tACS) | 16:19 |
@kanzure | transcription..? according to a paper? | 16:19 |
@fenn | yeah haven't you read any of the papers? supposedly it activates BDNF (a protein hormone) | 16:20 |
@kanzure | i have been occupied with a totally different set of things in working memory today | 16:20 |
@fenn | but there could be other mechanisms at work in addition to BDNF | 16:22 |
@fenn | want to study it? add another 1000 free parameters to your testing regime | 16:22 |
@fenn | poppingtonic: also considering that the only source of energy in the brain is oxygen, fMRI is mathematically equivalent to your idea, since burning more oxygen means more energy is emitted | 16:25 |

poppingtonic | fenn: there's another source of energy: light from the eyes. I think this is overlooked. | 16:28 |
@fenn | um, what? | 16:28 |
poppingtonic | https://www.refheap.com/17074 | 16:28 |
@fenn | are you a breatharian? | 16:29 |
poppingtonic | what is that? | 16:29 |
@fenn | uh, it doesn't matter | 16:29 |
@fenn | anyway you're vastly overestimating the signal to noise ratio available from (non-calorimeter) temperature measurements | 16:30 |
@fenn | let's make it easy, say you have a slice of neural tissue culture firing away on a microscope slide, and you point your microbolometer array at it | 16:31 |
poppingtonic | Oh, No no, I'm not a breatharian. | 16:32 |
@fenn | after a neuron fires, its temperature increases by, oh, let's say one microjoule | 16:32 |
poppingtonic | uh huh | 16:32 |
@fenn | hrm units units | 16:33 |
@kanzure | you should bug superkuh to say things about that | 16:34 |
poppingtonic | wow I just realized how speculative I was getting. | 16:36 |
@fenn | oh, water is 4.18J/g | 16:37 |
@fenn | degree | 16:37 |
@fenn | guh | 16:37 |
@fenn | i hate temperature units | 16:38 |
@kanzure | make your own | 16:39 |
@kanzure | and make sure it resolves to bits somehow | 16:39 |
poppingtonic | fenn: I understand how it would be extremely difficult to measure, since a synapse is such a tiny region of space, surrounded by a mass of (non-uniformly) heat-absorbent meat. I'd underestimated the s/n ratio. Some time in the future, maybe it'll be possible to run such an experiment and not get useless noisy data. | 16:40 |
@fenn | i'm not sure you'd ever get useful data out, even with perfect sensors | 16:41 |
@fenn | mostly because of the opacity of the skull, and of the brain itself | 16:42 |
@fenn | the CLARITY technique is useful because it makes the whole brain have the same refractive index (and thus it becomes clear to visible light) | 16:43 |
@kanzure | superkuh: ping | 16:43 |
poppingtonic | anannie: thanks for that link. Awesome. | 16:43 |

@fenn | i'm not sure what the transmittance (opacity) spectrum of the brain looks like | 16:44 |
@fenn | kanzure: is this for calculating the temperature rise or what? | 16:45 |
@kanzure | sort of. i'm trying to find the things superkuh would say if he was here. | 16:45 |
@kanzure | this isn't exactly the reference i was hoping for. but his collection was stolen/deleted a few years ago. | 16:45 |
@fenn | there's a lot more energy dissipated beyond just ohmic heating | 16:46 |
@fenn | by "a lot" i mean miniscule amounts, but relatively larger | 16:46 |
@fenn | heh i just got the "make sure it resolves to bits" reference | 16:48 |
@kanzure | all temperature things can eventually be resolved as being something to do with entropy and bits | 16:49 |
@kanzure | (insert handwaving here) | 16:49 |
@fenn | what is the entropy of one hand waving | 16:49 |
@kanzure | 1 | 16:49 |
@fenn | if a hand waves on the internet, does anybody care? | 16:49 |
@fenn | how many hands waving does it take to screw in a light bulb | 16:49 |
poppingtonic | kanzure it's 1/2 | 16:50 |
@kanzure | well to be honest i was trying to get him to complain about my unitless value | 16:50 |
@fenn | all units are unitless, dude | 16:50 |

fenn | the S stands for "solipsist" | 17:14 |
@kanzure | i wouldn't like github at all if i couldn't just type out the urls i want | 17:15 |
@kanzure | meanwhile sourceforge is still http://project.cvs.viewcvsweb.sourceforge.net/cvsroot/cvs/project/viewcvs.cgi/cgi-bin/TRUNK/myfile.c?diff | 17:16 |
fenn | they get a dollar every time you type "cvs" | 17:16 |
@kanzure | don't let the javascript rewrite stop you from hacking paperbot into working. | 17:17 |
@kanzure | because this pile of javascript is only for fetching | 17:17 |
@ParahSail1n | hm i already started a rewrite | 17:18 |
@kanzure | i call it papermonk | 17:18 |
@kanzure | and then something else will get to be called paperpunk | 17:18 |
fenn | shouldnt it be paperjunk | 17:19 |
@kanzure | no | 17:19 |
@kanzure | man you just shot me down on those two names | 17:20 |
@kanzure | i thought i was doing good | 17:20 |
cogitokat | fenn doesn't understand ): | 17:20 |
fenn | i thought "j for javascript, p for python, m for ... " | 17:20 |
@kanzure | oh, yeah, i don't know how to mentally resolve that conflict | 17:21 |
fenn | but i couldn't think of any programming languages with M besides matlab and ML, and those didnt make any sense | 17:21 |
@kanzure | i started naming my git repos python-whatever.git and then it would provide a "whatever" python egg. | 17:21 |
@kanzure | but then what is papermonk? node-papermonk? it runs in browsers too, so what's so node about it? | 17:21 |
poppingtonic | what about Malbolge? | 17:23 |
poppingtonic | paperclunk (clojure) | 17:23 |
@kanzure | i don't want to write in clojure | 17:23 |
poppingtonic | um, what? | 17:24 |
@kanzure | huh? | 17:24 |
poppingtonic | everybody should want to write in clojure :) | 17:24 |
@kanzure | the reason i chose javascript was because i could use my library to replace all of zotero's translators | 17:24 |
@kanzure | and then i can have zotero's 300,000 users maintain my scrapers for me | 17:24 |
@kanzure | imho their javascript infrastructure sucks a lot | 17:25 |
@kanzure | i don't think they even planned it out originally | 17:25 |
@kanzure | so the advantage of doing it this way is that i don't have to manually write scrapers for 300 academic publishers and their shitty html | 17:25 |
fenn | is it even possible to plan out a scraping system before you start? | 17:25 |
@kanzure | yeah | 17:25 |
@kanzure | zotero has shown that you don't require that many functions | 17:25 |
@kanzure | the way i have written the js version is highly modular | 17:26 |
@kanzure | each scraper is a separate module up on npmjs.org | 17:26 |
poppingtonic | whoever wants to write for specific publisher can do it themselves? | 17:26 |
@kanzure | and then there's a meta package (papermonk) that depends on all of those | 17:26 |
fenn | so are you rewriting zotero now? | 17:26 |
@kanzure | not quite | 17:26 |
@kanzure | zotero is still a firefox extension | 17:26 |
fenn | um, the zotero backend then | 17:26 |
@kanzure | sure. paperbot already does that in a few places. and why have both javascript and python doing the same thing? | 17:27 |
fenn | maybe this explains why i can't figure out what's going on in the existing codebase | 17:27 |
@kanzure | paperbot uses zotero translation-server to try zotero translators, then falls back to python, then falls back to scihub | 17:27 |
@kanzure | did you look at the README? | 17:27 |
@kanzure | the reason you don't understand it is because the code is a bunch of bullshit | 17:27 |

@nmz787 | i made a 90 degree bent tube in autodesk http://imgur.com/4mKBteB,FqbLDJm | 20:25 |
@nmz787 | processing in comsol now with turbulent flow setting | 20:26 |
@nmz787 | had to transfer it via iges, because the autodesk version is too new | 20:26 |
@nmz787 | well this isn't simple | 20:40 |

* heath sucks at regex | 21:23 | |
@kanzure | chances are high that regex is the wrong choice anyway | 21:24 |
* heath fetches http://libgen.info/view.php?id=897897 | 21:25 | |
@heath | if you're in python, correct | 21:25 |
@heath | if you're using the immature node ecosystem, and you don't have a decent robotsparser... | 21:26 |
@kanzure | how about require("robots") | 21:27 |

klafka | man it seems to me that # of cores hasn't really kept pace with amount of memory needed | 21:29 |
* klafka really wants an ec2 instance with 256gb of ram | 21:29 | |

klafka | i'm not buying computers | 21:30 |
@kanzure | i think jrayhawk recently acquired himself a 32 core thing? | 21:30 |
klafka | well i have a 32 core machine | 21:30 |
klafka | but only 144gb ram | 21:30 |
klafka | that's only 4.5gb per core | 21:31 |
klafka | wow wait nvm | 21:32 |
klafka | they upgraded them to 244 | 21:32 |
klafka | oh cool | 21:32 |
