00:27 < kanzure_> huh
00:27 < kanzure_> "Obtaining carbon nanotubes from grass"
00:28 < kanzure_> rapid heat treatment to 600 degrees celsius. CNTs have widths between 30 and 50 nm.
00:31 < kanzure_> god this method sucks
00:31 < kanzure_> 50 steps of the 600 deg-C heat treatment procedure, plus "15 m l of oxygen" (but not liquid oxygen??)
00:31 < gene_> hahahahahahahahaha
00:31 < kanzure_> and then drying at 90 degrees celsius for 5 hours
00:32 < kanzure_> and then at the end, the estimated average yield is 15%
00:32 < gene_> wow I would expect ten percent
00:32 < gene_> I mean 5
00:32 < kanzure_> well I think rolling your fingers around on graphite has a better yield rate of CNTs than this method
00:32 < kanzure_> but I'm not entirely sure yet

18:31 < kanzure_> yeah?
18:31 < kanzure_> you interrupt an amazing game of tetris, speak!
18:31 < kanzure_> bkero: ?
18:34 < bkero> You do some crazy OCR stuff, yes?
18:42 < kanzure_> Sometimes. No.
18:43 < kanzure_> The crazy OCR stuff I use tends to suck.
18:46 < bkero> I'm looking for some ocr software
18:46 < bkero> ocropus wouldn't compile
18:48 < kanzure_> tesseract
18:48 < kanzure_> but it sucks. they all suck.
18:57 < bkero> :/
18:57 < bkero> I was going to try to get some OCR for kana, but I figured I'd start with english first
18:57 < bkero> gocr is pretty terrible
19:05 < kanzure_> gocr?
19:08 < kanzure_> http://en.wikipedia.org/wiki/The_Real_Superhumans
19:09 < kanzure_> it's very specieist (i.e., claiming "it's a new species!")
19:15 < bkero> gocr is gnu ocr, it's really shitty
19:36 < kanzure_> "Jamie Ward" is apparently hunting down genes for synthesia

19:37 < kanzure_> http://www.syn.sussex.ac.uk/x2008.html
19:41 < ybit> what's the error you receive when compiling octopussy bkero?
19:42 < ybit> (i know it's not the name, but i like using that one better :)
19:44 < kanzure_> huh, they actually say LSD has a legitimate role in synthesthesia
19:44 < kanzure_> not sure how much I believe that. LSD happening to have the same exact effect as some genetic irregularity or crosswiring?
19:45 < kanzure_> "(2) We encountered two subjects in whom Prozac inhibited synesthesia. Prozac being an SSRI increases serotonin and activates S1 receptors – hyperactivation of which is known to inhibit S2a [7]."
19:45 < kanzure_> fuck.
19:46 < kanzure_> "implicates gene HTR2A on chromosome 13q as the underlying cause of synesthesia."
19:46 < kanzure_> well that's highly specific..

22:43 < kanzure_> I think I've underestimated just how accessible ubuntu has made it for developers to work with linux
22:43 < kanzure_> I'm starting to notice much more linux support in random projects since it's as simple as burning a CD
22:43 < kanzure_> although live CDs have been around for a while before ubuntu

22:51 < meoblast001> hola
22:51 < kanzure_> aloha, I see you're also in #wrongplanet
22:51 < meoblast001> yes
22:52 < meoblast001> i'm everywhere
22:52 < kanzure_> did you see the list of channels that I monitor on my home page?
22:52 < meoblast001> no i didn't see that
22:52 < meoblast001> i skimmed over your page
22:52 < meoblast001> there was a lot of material
22:53 < meoblast001> i've been in a lot of those
22:53 < meoblast001> kanzure_: thebolt said it was a driver issue
22:53 < kanzure_> so it sounds like we've just not run into each other before
22:54 < meoblast001> i've been in #linux #debian #ubuntu #osdev #electronics and that's about it
22:55 < meoblast001> my "personal" page is www.meoblast001.mysticgalaxies.com
22:56 < kanzure_> what is JBED?
22:57 < kanzure_> huh, crystalspace installed correctly on my debian box including the libraries
22:58 < kanzure_> so maybe I'll just wait until tomorrow to run grandwing
22:59 < meoblast001> oh JBED is something a few friends of mine set up
22:59 < meoblast001> kanzure_: do any of the CS tests run?
22:59 < meoblast001> try running simptest or whatever it's called
22:59 < meoblast001> i think it's simple1
23:00 < kanzure_> I'm not sure how I will confirm whether or not they work unless I remember how to do X forwarding
23:00 < kanzure_> ssh -X is enough, right?

23:00 < gene> kanzure are you awake?
23:00 < kanzure_> gene: yes
23:01 < meoblast001> i've never done xforwarding
23:05 < fenn> http://www.polarization.com/haidinger/haidinger.html
23:07 < gene> have you seen it?
23:08 < gene> Haidingers brush?
23:14 < meoblast001> Haidingers brush?
23:14 < fenn> nup
23:15 < fenn> often i see things i can't explain
23:15 < gene> I saw a statistical anomaly today
23:15 < fenn> ..and what was that?
23:16 < fenn> all the tea molecules in your teacup just spontaneously moved in the same direction?
23:16 < gene> no
23:16 < meoblast001> wow i just did something i've always wanted to do
23:17 < fenn> you guys are so vague
23:17 < kanzure_> I'm not, I'm not!
23:17 < kanzure_> I seem to have the direct opposite problem
23:17 < kanzure_> which side of the CD is the non-shiny side again? :/
23:17 < gene> I saw the end of the bell curve
23:17 < kanzure_> really? how'd it look?
23:17 < gene> I saw a man in a digg t-shirt dating a girl
23:18 < fenn> are you sure it was a girl?
23:18 < gene> 1/0
23:18 < kanzure_> digg is popular these days, that's not an anomaly
23:18 < gene> it's a running joke on digg that everyone on digg lives in the basement
23:18 < kanzure_> that's the internet, you mean
23:19 < gene> oh and vote for moot
23:21 < gene> kanzure do you have a constant voltage power supply I could borrow?
23:22 < kanzure_> I have two computers that I'm giving away
23:23 < kanzure_> both have power supplies
23:24 < gene> I don't care that they're from a computer
23:24 < gene> I just care that they supply electricity
23:24 < gene> I want to see if I can't get away with electroetching in my dorm room
23:25 < kanzure_> how will you do this?
23:26 < gene> tupperware+salt+paperclip+wire+aluminum+ paint
23:27 < gene> + stainless steel
23:27 < gene> if the coop has it
23:27 < kanzure_> stainless steel in what form? not the paperclip?
23:27 < gene> not the paper clip
23:27 < gene> coop sells stainless steel
23:27 < gene> when it's in stock
23:27 < gene> if it's in stock
23:27 < kanzure_> you go up to their desk and ask for stainless steel?
23:28 < gene> no you go to the back where the balsa wood is
23:29 < meoblast001> what's this place about?
23:29 < gene> they sell sheets of plastic too, you might find those useful for sharpie microfluidics...
23:30 < kanzure_> meoblast001: on the UT Austin campus, there's a co-op store that sells stuff for ridiculously marked up prices, and I guess they also sell materials
23:30 < meoblast001> that's what this channel is about?
23:31 < gene> ridicoulusly marked up prices shit
23:31 < kanzure_> oh, well, the channel's name is derived from some thinking about transhuman technologies
23:31 < gene> I should have brought my aluminum from home...
23:31 < kanzure_> but more recently we've been working on some open manufacturing initiatives
23:31 < kanzure_> fenn's been working at an up-and-coming fablab, for instance
23:31 < kanzure_> but mostly we sit around and complain about debian packages :)
23:31 < kanzure_> http://heybryan.org/om.html
23:31 < meoblast001> oh
23:32 < kanzure_> don't know if you know about transhumanism.
23:32 < meoblast001> speaking of complaining about debian packages
23:32 < meoblast001> i made a few
23:32 < kanzure_> were you able to get debian developer status?
23:32 < meoblast001> haha no
23:32 < meoblast001> www.meoblast001.mysticgalaxies.com/debs.html
23:33 < gene> kanzure so what paper mentioned making microfluidic channels with 0.2 micron channel sizes
23:33 < kanzure_> gene: the CD paper.
23:33 < kanzure_> one sec.
23:33 < kanzure_> http://heybryan.org/books/papers/microfluidics/Patterning%20Design%20in%20Color%20at%20the%20Submicron%20Scale%20-%20Arun%20Chattopadhyay.pdf
23:34 < kanzure_> meoblast001: this stuff about sharpie microfluidics is related to 'diybio', or doing genetic engineering at home
23:34 < meoblast001> lol
23:34 < kanzure_> the idea there being that it may somehow be helpful for transhuman technologies, or something
23:34 < kanzure_> i.e., purifying insulin or something at home by drawing circuits with sharpies.. maybe.
23:35 < gene> well I hope the end result is a DNA synth anyone can make
23:35 < kanzure_> right
23:35 < kanzure_> did you read the document on the source of oligonucleotide synthesis errors, gene?
23:35 < gene> so you can download and compile say insulin gene
23:35 < kanzure_> http://heybryan.org/mediawiki/index.php/DNA_synthesizer <- I listed the sources and some references from a good paper/thesis I read.
23:36 < kanzure_> ah, here we go: http://heybryan.org/mediawiki/index.php/DNA_synthesizer#Origin_of_oligonucleotide_impurities_and_errors
23:37 < kanzure_> it was funny, the other night I had my grandmother and sister sitting down at the dinner table doing sharpie microfluidics
23:40 < ybit> heh, now that is funny. a little off though, typically the grandmother is sharing a tradition with the youngsters at the dinner table :)
23:41 < kanzure_> grandma ain't wanting to die
23:41 < kanzure_> (this is the same one that sent me some "Vernor Vinge literature" to "educate" me)
23:42 < meoblast001>  programming is fun :P
23:42 < kanzure_> meoblast001: yes :)
23:42 < kanzure_> as it happens, programming organisms is also fun
23:43 < gene> so in this CD paper they burn some data too it, take it apart and use it as a mold
23:43 < kanzure_> wait, what?
23:43 < fenn> rainbows end? :)
23:43 < kanzure_> that might be the wrong paper then
23:43 < kanzure_> this is the one where they press the CD down into sharpie ink blotch
23:43 < kanzure_> and are able to get 0.2 micron microchannels
23:44 < kanzure_> which one are you thinking of, gene?
23:45 < gene> no that's the right paper
23:45 < gene> is it just sharpie ink
23:45 < kanzure_> I thought so
23:45 < kanzure_> if you burn data to a CD, you're just making it like a photomask basically
23:45 < kanzure_> and I'm not even sure if it's a good photomask
23:46 < kanzure_> because the dye becomes non-transparent to the light that the CD reading laser uses
23:46 < kanzure_> (it's a photoactive dye thingy)
23:46 < gene> well they said something about aluminum foil
23:47 < kanzure_> lemme go re-read
23:47 < kanzure_> sounds kind of important
23:48 < gene> doesn't sound very useful
23:48 < gene> can only be used to make paralell lines
23:48 < kanzure_> better than nothing.
23:49 < kanzure_> I would like to try a burned CD as a photomask sometime though
23:49 < kanzure_> I'm not even sure if that's a stupid idea or not
23:50 < gene> well um....
23:50 < gene> how do you get a consistent pattern on a cd
23:50 < kanzure_> you burn data at specific points on the disk
23:51 < kanzure_> it's all "zeroes and ones" (masked or unmasked)
23:51 < kanzure_> so you just need to do the right radial point conversion formula, I guess
23:51 < kanzure_> to map your image to the physical structure of the disk.
23:51 < kanzure_> this is usually called an ISO file
23:51 < gene> some one did that
23:51 < kanzure_> oh?
23:51 < gene> yeah saw it on hackaday
23:51 < gene> a while back
23:51 < kanzure_> well, link?
23:52 < gene> this might take awhile
