| kanzure_ | huh | 00:27 |
| kanzure_ | "Obtaining carbon nanotubes from grass" | 00:27 |
| kanzure_ | rapid heat treatment to 600 degrees celsius. CNTs have widths between 30 and 50 nm. | 00:28 |
| 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 | 00:31 |
| 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 | 00:32 |

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

| ybit | what's the error you receive when compiling octopussy bkero? | 19:41 |
| ybit | (i know it's not the name, but i like using that one better :) | 19:42 |
| 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? | 19:44 |
| 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. | 19:45 |
| kanzure_ | "implicates gene HTR2A on chromosome 13q as the underlying cause of synesthesia." | 19:46 |
| kanzure_ | well that's highly specific.. | 19:46 |

| 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 | 22:43 |

| meoblast001 | hola | 22:51 |
| kanzure_ | aloha, I see you're also in #wrongplanet | 22:51 |
| meoblast001 | yes | 22:51 |
| 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 | 22:52 |
| 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 | 22:53 |
| meoblast001 | i've been in #linux #debian #ubuntu #osdev #electronics and that's about it | 22:54 |
| meoblast001 | my "personal" page is www.meoblast001.mysticgalaxies.com | 22:55 |
| kanzure_ | what is JBED? | 22:56 |
| kanzure_ | huh, crystalspace installed correctly on my debian box including the libraries | 22:57 |
| kanzure_ | so maybe I'll just wait until tomorrow to run grandwing | 22:58 |
| 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 | 22:59 |
| 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 | Haidingers brush? | 23:08 |
| meoblast001 | Haidingers brush? | 23:14 |
| fenn | nup | 23:14 |
| 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? | 23:15 |
| 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 | 23:16 |
| 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 | 23:17 |
| 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 | 23:18 |
| gene | oh and vote for moot | 23:19 |
| gene | kanzure do you have a constant voltage power supply I could borrow? | 23:21 |
| kanzure_ | I have two computers that I'm giving away | 23:22 |
| kanzure_ | both have power supplies | 23:23 |
| 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 | 23:24 |
| kanzure_ | how will you do this? | 23:25 |
| gene | tupperware+salt+paperclip+wire+aluminum+ paint | 23:26 |
| 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? | 23:27 |
| gene | no you go to the back where the balsa wood is | 23:28 |
| meoblast001 | what's this place about? | 23:29 |
| gene | they sell sheets of plastic too, you might find those useful for sharpie microfluidics... | 23:29 |
| 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? | 23:30 |
| 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 | 23:31 |
| 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 | 23:32 |
| 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 | 23:33 |
| 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. | 23:34 |
| 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. | 23:35 |
| kanzure_ | ah, here we go: http://heybryan.org/mediawiki/index.php/DNA_synthesizer#Origin_of_oligonucleotide_impurities_and_errors | 23:36 |
| kanzure_ | it was funny, the other night I had my grandmother and sister sitting down at the dinner table doing sharpie microfluidics | 23:37 |
| ybit | heh, now that is funny. a little off though, typically the grandmother is sharing a tradition with the youngsters at the dinner table :) | 23:40 |
| 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) | 23:41 |
| meoblast001 | programming is fun :P | 23:42 |
| kanzure_ | meoblast001: yes :) | 23:42 |
| kanzure_ | as it happens, programming organisms is also fun | 23:42 |
| 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 | 23:43 |
| kanzure_ | which one are you thinking of, gene? | 23:44 |
| 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 | 23:45 |
| 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 | 23:46 |
| kanzure_ | lemme go re-read | 23:47 |
| kanzure_ | sounds kind of important | 23:47 |
| gene | doesn't sound very useful | 23:48 |
| gene | can only be used to make paralell lines | 23:48 |
| kanzure_ | better than nothing. | 23:48 |
| 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 | 23:49 |
| 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 | 23:50 |
| 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? | 23:51 |
| gene | this might take awhile | 23:52 |
