chris_99Has anyone ever seen a tool to roughly guess what the title is from a pdf, possibly via simple heuristics like looking what the text on the top of the first page in bold is06:51
Cooler_you can use screenshot with X11 and try gOCR to get title07:04
Cooler_tesseract too... other view convert PDF to PNG and reconize with SVM etc...07:04
kanzurean easier way would be to search for a doi number and then query some doi metadata service for the title07:25
kanzurecpopell6: jojack is back to doing competitions you should challenge him07:25

cpopell6kanzure : power or bodybuilding?07:27
chris_99hmm they are pure text pdfs Cooler_, so i could inspect them i guess.  They're not all papers though, so i don't think i can use a doi number07:33
kanzurecpopell6: didn't ask but sounded like bodybuilding07:34
cpopell6kanzure : meh07:42

kanzurealthough i think he stopped power lifting because of joint problems or something, i don't know08:30
kanzurejust call him an old man maybe that will work08:30

nmz787_ichris_99: I've used tesseract pretty successfully to extract text from PDFs10:57
nmz787_iI was parsing PDFs on property for sale by the state sheriffs (foreclosures I guess)10:58
nmz787_ifor some reason they uploaded scans of the real documents, embedded in PDF format10:58
chris_99nmz787_i, sorry i wasn't clear originally, these are just pdfs with normal text in, (rather than images of text) i was just looking for something to guess the title by looking for the heading text in bold or something10:58
nmz787_iand I wanted to get all the addresses of available listings, and plot them on a map, to see what was close to me10:59
chris_99cool11:01
chris_99i've played with tesseract a little bit before, it seems to work pretty well11:01

nmz787_ior if you can't determine bold characters or whatever, through something like PDFminer11:09
chris_99oh pdfminer looks good, i've played with a pdf lib before but the one i used wasn't great11:13

nmz787_iFourFire: I find that I scan pages a lot faster than it would take to read every word serially12:33
FourFirenmz787_i, specific directed method or just habitual?12:33
nmz787_iidk if this is just faster serial scanning, or if I also use my peripheral vision... or some sort of random walk or binary search tree to elucidate text of interest/importance12:33
nmz787_iFourFire: I guess habitual12:34
nmz787_ibut I may have directed myself in an evolutionary fashion12:34
FourFireany pointers, how much opf your fov you use, lighting (physical, screen, colours which help?)12:34
nmz787_iI havent followed any specific formal speedreading methodology12:34
nmz787_ihmm, no I guess its just keyword and phrase extraction that I'm doing12:35
nmz787_iit probably comes from project-based research12:35
nmz787_iwhere I sort of know what I am looking for12:35
nmz787_iso i probably skip reading large portions because of how they look or their context (provided by a bold section title or paragraph breaks)12:36
FourFireIn the same line of inquiry: does anyone use music for cognitive enhancement of any kind?12:37
nmz787_iI am much slower at reading things like story books or text books where I am not specifically researching a given thing12:37
nmz787_iFourFire: I like to loop music when I do listen to things while I work12:37
FourFirewhat kind of music?12:37
nmz787_iall sorts12:37
FourFireexamples?12:38
nmz787_isouthern hip hop, romanian folk music, techno, blues, bollywood12:38
FourFireis music you enjoy listening to distinct from music which helps you be productive?12:38
FourFireAH, you "like to listen to music" but does it actually help?12:39
nmz787_iI generally don't like story music... if the music has lyrics, while I study12:39
nmz787_ialso don't like listening to conversation, too distracting12:39
nmz787_iFourFire: it helps depending on the mood12:39
nmz787_iproductivity for me is more tied to hating that I must use a keyboard and mouse for input, and that I need to sit co-planar to this rigidly-placed display screen12:41
nmz787_iI can be thinking and very mentally productive, but not want to lift a damn finger... so productivity can be null in such cases12:41

nmz787_iFourFire: I figure some sort of many-detector EEG tomography could be interesting15:22
nmz787_iI also have some ideas about phase-shifted brainwaves being useful for encoding/decoding info15:23
nmz787_ibut I would basically need many high sample rate, low noise analog to digital converters, recording data while listening to music, thinking about that same music (playing it back in your mind's ear) and trying to match  frequency signatures or something15:24
nmz787_iso far though, I haven't seen anyone recording EEG with gigahertz sample rates15:25
nmz787_iwhich is extremely dissatisfying to me15:25

kanzure"Another reason for lack of interest in pursuing this approach is that it is a research dead end on the road to developing reversible tissue preservation in the nearer future."15:47
kanzurethat's not a great argument15:47
kanzure"What we can note is that Robert McIntyre, the lead researcher on ASC at 21st Century Medicine, made a point during his presentation at the Alcor 2015 Conference of recommending against adoption of ASC in cryonics at this time."15:48
kanzure"For cryonics under ideal conditions, the damage that still requires future repair is now more subtle than freezing damage. That damage is believed to be chiefly cryoprotectant toxicity and associated tissue dehydration. It’s time for cryonics debate to move past ill-informed beliefs of “cells bursting.”"15:48
kanzurewait what? toxicity and dehydration are the two problems?15:48
kanzurewell maybe dehydration is such a big problem that it eclipses other big problems. but i feel like they would have mentioned the other ones.15:49

nmz787_ichris_99: how else would you detect slow signals overlapping in phase by relatively short amount of time?15:59
nmz787_ii.e. a nerve might take micro/milliseconds to fire, but if you have 10,000 firing at once in your audio-processing neural circuitry... and if its some sort of pulse-code-modulation... then you'16:00
nmz787_iyou'd need higher sample rate to collect all the offset data16:00
nmz787_iand extending that, for something like vision...maybe you'd have even more parallel stuff going on16:01
