| --- Day changed Fri Jun 19 2009 | ||
| ybit | so a few questions, who is doing the led photolith device and is it in a clean room, how clean if so, what was or is being used to make it like so? | 00:00 |
|---|---|---|
| genehacker | I have no idea | 00:01 |
| genehacker | ask kanzure | 00:01 |
| ybit | ooh, me likey: "A photo-polymerization resist for UV nanoimprint lithography" | 00:04 |
| genehacker | find me how to make photolabile phosphoramidites from chemicals under your kitchen sink and you made my day | 00:05 |

| ybit | kanzure: who's the led photolith person? | 09:53 |
| ybit | ..in austin | 09:53 |
| kanzure | there isn't one | 09:58 |
| kanzure | are you sure it requires a clean room? | 09:59 |
| kanzure | the polymer should polymerize in blue light in spite of dust in the environment | 09:59 |
| kanzure | though it's probably a good idea to set up a clean room anyway since bio protocols tend to rely on that. | 10:01 |
| kanzure | sort of a "while you're at it" thing | 10:01 |

| ybit | i took a quick glance at the paper yesterday, it estimated that the cost of the setup was a little under$6k | 10:16 |
| kanzure | the uv photolithography paper? | 10:17 |
| kanzure | there are some ways that fenn and I were talking about reducing the costs of that setup | 10:18 |
| kanzure | it's somewhere in the logs in here | 10:18 |
| kanzure | ybit: I sent you an email with a list of projects and their estimated costs. please confirm, or something. | 10:24 |

| ybit | i was wrong about spain, there is a neuroeng program there, in barcelona | 10:57 |
| ybit | however, it's all in-vitro :\ | 10:57 |
| kanzure | that's better than "all in silico" | 10:58 |
| kanzure | is that DeMarse? | 10:58 |
| ybit | and supposedly they developed a "UV laser scanning direct-lithography system" but i've yet to see schematics | 10:58 |
| kanzure | er, wait, DeMarse is at gatech.edu | 10:59 |
| kanzure | nevermind | 10:59 |
| ybit | he's in florida now | 10:59 |
| ybit | i think ucf | 10:59 |
| ybit | he's at ufl | 11:00 |

| fenn | "If you are serious, you could take out your biggest dust problem. Your carpet." | 11:19 |
| fenn | from "how to make a clean room" | 11:20 |
| ybit | or you could place some type of plastic over it | 11:21 |
| ybit | save some $ | 11:21 |
| kanzure | why do you have carpet in the first place | 11:21 |
| ybit | true that | 11:22 |
| ybit | it's difficult to find an apartment that doesn't have carpet in a small city like florence | 11:23 |
| kanzure | craigslist should have a basement being listed somewhere | 11:23 |
| kanzure | texas is the only place in the world that doesn't do basements apparently, or something | 11:23 |
| fenn | because then you could stay cool without needing air conditioning | 11:24 |
| fenn | = bad for economy | 11:24 |
| kanzure | there are people going around here in austin with cam corders fitted with infrared filters claiming that they do an "energy assessment" of your place of dwelling and that you need to hire them before you sell your house :p | 11:26 |
| kanzure | set([frozenset([1,2]), frozenset([1,2]), frozenset([3,4])]) | 11:27 |
| kanzure | yay I like this | 11:27 |
| fenn | is there some methodology for testing your script's output besides "does it load?" | 11:27 |
| kanzure | which script | 11:28 |
| fenn | i'm trying to add dimensions and graphsynth complains about something, somewhere in the file | 11:28 |
| kanzure | which file? | 11:28 |
| kanzure | how about you just paste the command line stuff instead :p | 11:28 |
| fenn | "bad input string format" and i think it means character 8473 but there's nothing special there | 11:28 |
| fenn | it's graphsynth, there's no command line | 11:28 |
| kanzure | which file are you loading into graphsynth? | 11:29 |
| -!- kardan| [n=kardan@p54BE5BE1.dip.t-dialin.net] has quit [Success] | 11:29 | |
| fenn | squirtgun.dim.gs2.gxml | 11:29 |
| kanzure | and how did you generate it | 11:29 |
| -!- kardan| [n=kardan@p54BE5BE1.dip.t-dialin.net] has joined #hplusroadmap | 11:29 | |
| fenn | load into graphsynth, save, run gxml-add-dimensions.pl | 11:29 |
| kanzure | ok, so you loaded it into GS 2.0, then ran gxml-add-dimensions.pl, and now are trying to load it back into GS 2.0 ? | 11:30 |
| fenn | yep | 11:30 |
| kanzure | does squirtgun.dim.gs2.gxml have any <opt> bullshit at the top? | 11:30 |
| fenn | yes | 11:31 |
| kanzure | that's non-good | 11:31 |
| fenn | i changed it to Page but it didnt change the error message | 11:31 |
| kanzure | but why would you think that has something to do with character 8473 in the file? | 11:31 |
| kanzure | hm | 11:31 |
| kanzure | ok, is the file somewhere I can fetch it? | 11:31 |
| fenn | yes | 11:31 |
| kanzure | a link would be more helpful | 11:31 |
| fenn | http://adl.serveftp.org/lab/fenn/squirtgun.dim.gs2.gxml | 11:31 |
| kanzure | I still see opt in there | 11:32 |
| kanzure | did you change it back afterwards? | 11:32 |
| fenn | wah | 11:32 |
| fenn | i did the editing on windows | 11:32 |
| fenn | actually it starts out complaining about the <double></double> | 11:32 |
| fenn | so i did search/replace to <double>0</double> | 11:33 |
| kanzure | that's an ok error | 11:33 |
| kanzure | yeah | 11:33 |
| fenn | then it complained about something else, which i cant figure out | 11:33 |
| kanzure | where did I put the example gs 2.0 gxml files | 11:33 |
| kanzure | the only thing that I can come up with is that maybe it's not enough to replace "opt" with "Page" and there's some more elements that we're forgetting | 11:33 |
| fenn | the weird thing is the character number doesnt change even if i add stuff to the file | 11:34 |
| kanzure | example: http://adl.serveftp.org/lab/gs2/GraphSynth2/input/waterLifter.gxml | 11:34 |
| kanzure | is this some sort of weird unicode encoding issue or something? | 11:34 |
| ybit | kanzure, did anyone ever respond to your "Personal science libraries?" on mea-users? | 11:35 |
| fenn | that doesnt have any xaml stuff | 11:35 |
| fenn | or local variables | 11:35 |
| kanzure | ybit: only one guy, but he didn't do anything. | 11:35 |
| fenn | and it uses shapekey | 11:35 |
| -!- kardan| [n=kardan@p54BE5BE1.dip.t-dialin.net] has quit [Read error: 60 (Operation timed out)] | 11:35 | |
| fenn | so that's a terrible example 2.0 file | 11:35 |
| kanzure | that's a 1.9 apparently | 11:35 |
| kanzure | arr | 11:35 |
| kanzure | ok maybe better: http://adl.serveftp.org/lab/gs2/GraphSynth2/input/swirlSeed.gxml | 11:36 |
| kanzure | no local variables however, but that shouldn't be a problem | 11:36 |
| kanzure | oh what version of gs 2.0 are you using anyway? where did you get the copy from? | 11:36 |
| fenn | there is an exeutable on newton and also source/visual stuffio | 11:37 |
| fenn | i stepped through the loading process with the debugger even | 11:37 |
| fenn | didnt seem to do anything useful | 11:37 |
| kanzure | ok, so I guess it's time for twitchy debugging | 11:38 |
| kanzure | um | 11:38 |
| kanzure | try a regexp to remove <localVariables> to </localVariables> and replace with <localVariables /> to see if the non-localVariables version works | 11:38 |
| fenn | what does that mean? | 11:39 |
| kanzure | try a regexp to remove <localVariables> to </localVariables> and replace with <localVariables /> to see if the non-localVariables version works | 11:39 |
| kanzure | this problem did not happen with tanin, daniel or matt for that matter | 11:39 |
| * fenn wonders if there's a decent code editor on windows | 11:39 | |
| kanzure | visual studio is the only one that seems to have a search-and-replace mechanism, but it doesn't handle regular expressions | 11:39 |
| kanzure | hm | 11:41 |
| kanzure | in the example gs 2.0 gxml file, there's no </Canvas> | 11:41 |
| kanzure | I think it would be safe to get rid of <Canvas> to </Canvas> in your squirtgun.dim.gs2.gxml file | 11:41 |
| kanzure | and try that too.. | 11:41 |
| kanzure | weird. in squirtgun.gs2.gxml, the </Canvas> does not appear on its own line. (not that this matters) | 11:43 |
| -!- kardan| [n=kardan@p54BE5BE1.dip.t-dialin.net] has joined #hplusroadmap | 11:45 | |
| fenn | ok nevermind, it loads on darwin after s/<double></<double>0</ | 11:48 |
| kanzure | I thought you did that already | 11:48 |
| fenn | i was on newton | 11:48 |
| fenn | so newton is just broke | 11:48 |
| kanzure | so it was a "crappy version of gs2.0 because of a lack of version control" | 11:48 |
| fenn | probably something like that, yes | 11:48 |
| kanzure | wowee. glad we're being paid for this.. | 11:49 |
| kanzure | oh wait. | 11:50 |
| kanzure | fenn: what's the title on the GS 2.0 main window? | 12:01 |
| * kanzure is editing the source to add a version number to the title bar | 12:01 | |
| kanzure | oh, or a way to add the svn revision number upon checkout | 12:02 |
| kanzure | http://subversion.tigris.org/faq.html#version-value-in-source | 12:03 |
| kanzure | yay | 12:03 |
| kanzure | fenn: can you ask tanin if he has installed TortoiseSVN yet and if he can't figure it out to give me a call today? since he's editing the source, he should be committing his changes to a new directory under svn or something | 12:07 |

| fenn | apparently (according to tanin) the current SVn won't work, so he's using some older version | 12:31 |
| fenn | i still havent figured out wtf is going on | 12:31 |
| kanzure | the current checkout from svn? | 12:37 |
| kanzure | er, I mean to ask: is tanin claiming that the latest checkout from svn is not working? | 12:37 |
| fenn | summary: running latest svn on newton and darwin; open the gxml-add-dimensions output (suitably edited) only works on newton | 12:52 |
| fenn | er, only works on darwin | 12:52 |
| fenn | but, if i save the opened file and open that on newton, it works | 12:52 |
| kanzure | wtfage | 12:52 |
| kanzure | newton is XP and darwin is what? | 12:52 |
| fenn | so i'm doing a diff new | 12:52 |
| fenn | darwin is windows 7 | 12:53 |
| kanzure | oh wise diff, what say ye? | 12:53 |
| fenn | one moment | 12:54 |
| kanzure | interesting how the lab is simultaneously capable of violating all known laws of computing. like those of cross-platform compatabilism. | 12:55 |
| fenn | uh. speaking of violating laws of computing | 12:57 |
| fenn | the diff was null | 12:57 |
| fenn | so i must have messed up somewhere | 12:57 |
| kanzure | what did you diff? | 12:58 |
| fenn | diff squirtgun.dim.gs2.gxml squirtgun.dim.gs2.loaded.gxml | 12:58 |
| kanzure | diff (1) gxml-add-dimensions' output and (2) newton's saved version of #1. | 12:58 |
| kanzure | hm | 12:58 |
| fenn | yep | 12:59 |
| kanzure | is diff going to pick up something minor that windows would complain about? | 12:59 |
| fenn | i thought i moved some nodes around though so i should have gotten that at least | 12:59 |
| kanzure | is there a -strict or something? :/ | 12:59 |
| kanzure | wonder if the upload process fixes the problem or something. sometimes FTP works in ASCII or binary mode, which screws with files. | 13:00 |
| fenn | right | 13:00 |
| kanzure | ok, so upload the file to the box that you do your diff on, then copy the file to /var/www/something/ and then go get that on newton :p | 13:00 |
| kanzure | um, wait | 13:00 |
| kanzure | you probably shouldn't. | 13:01 |
| kanzure | I am a very puzzled guy right now. | 13:01 |
| fenn | i could make a flowchart :) | 13:02 |
| kanzure | ooh | 13:02 |
| kanzure | so, if you open and save it on darwin first, are you loading it on newton with the latest svn version? or the old version | 13:02 |
| kanzure | did you try loading the gxml-add-dimensions output on newton's old version *and* svn up'd version? | 13:02 |
| fenn | both running svn | 13:03 |
| kanzure | how do you know this isn't an internet explorer or firefox caching error on newton's part | 13:03 |
| fenn | gxml-add-dimensions was from newton, i dont know which version i ran | 13:03 |
| kanzure | that sentence made no sense | 13:04 |
| kanzure | please sentence the form in a question of the answer | 13:04 |
| fenn | gxml-add-dimensions only works on 2.0 files so i had to run it through graphsynth to get 2.0 | 13:04 |
| kanzure | yes | 13:04 |
| fenn | i did that on newton yesterday | 13:04 |
| kanzure | how are you checking that the pre-darwinized gxml file does not work on newton? | 13:05 |
| kanzure | is it over http that you download the gxml file on newton? | 13:05 |
| fenn | yes, from lab/fenn/ | 13:05 |
| kanzure | that might be it | 13:06 |
| kanzure | I had this weird caching problem with daniel once | 13:06 |
| kanzure | he would refresh the page and get the same damn XML file even though I knew I had updated it to something different | 13:06 |
| fenn | but so what, i hadnt updated it anyway | 13:06 |
| fenn | i.e. i did the editing in windows to make it load | 13:06 |
| fenn | (but iwt wouldnt load) | 13:06 |
| kanzure | ok, so you did the editing on windows to make it load (but it didn't in both svn up'd and previous crap version) | 13:07 |
| kanzure | so you transferred it then over to darwin? | 13:07 |
| fenn | yes, but i downloaded the same file to darwin from lab/fenn/ | 13:07 |
| fenn | then edited it again, then loaded it | 13:08 |
| kanzure | wah | 13:08 |
| fenn | meanwhile, back on unix, i edit it yet again | 13:08 |
| fenn | then i transfer the saved file to newton, try to load it, and it loads | 13:09 |
| fenn | (from darwin) | 13:09 |
| kanzure | on unix, you edit [what] again? | 13:09 |
| fenn | on unix i edit lab/fenn | 13:09 |
| fenn | lab/fenn/squirtgun.dim.gs2.gxml | 13:09 |
| kanzure | ok, so you did the editing in your favorite editor instead of on windows that time around | 13:09 |
| fenn | and upload from newton to dokuwiki | 13:09 |
| fenn | then download to unix as .loaded.gxml | 13:10 |
| kanzure | er, what? why upload from newton? | 13:10 |
| kanzure | ok | 13:10 |
| fenn | then diff, and the diff is null | 13:10 |
| kanzure | why not .loaded.gxml saved from darwin? | 13:10 |
| fenn | hm. my story doesnt make sense does it | 13:10 |
| fenn | how did i transfer from darwin to newton? | 13:10 |
| kanzure | if you edited it on linux, from the gxml-add-dimensions.pl output, did you ever then go load *that* to the svn up'd version on newton? | 13:11 |
| fenn | no | 13:11 |
| kanzure | why did you ever edit it on minsky (or davinci I guess) then? :p | 13:12 |
| fenn | because i was sick of doing the same edit over and over | 13:12 |
| kanzure | ok | 13:12 |
| kanzure | and after doing that | 13:12 |
| kanzure | what boxes have successfully loaded that edit into gs 2.0? | 13:12 |
| fenn | none | 13:12 |
| kanzure | do they all error? | 13:13 |
| fenn | never tried to load it | 13:13 |
| kanzure | this would be the one thing that you would want to know I thought | 13:13 |
| kanzure | because it shouldn't only work if it goes through darwin first .. | 13:13 |
| kanzure | it should work if it goes through newton too since it's the same damn software | 13:14 |
| kanzure | the same input files: your edited version on lab/fenn/ that you edited by hand on minsky | 13:14 |
| fenn | yep | 13:14 |
| kanzure | the same svn up'd revision number on darwin and newton | 13:14 |
| kanzure | and when you get that unix edited file on newton, gs 2.0 should be able to open it up | 13:14 |
| fenn | one would think so | 13:14 |
| kanzure | but you just told me you never tried to load it | 13:15 |
| kanzure | so how would you know | 13:15 |
| kanzure | diff (1) gxml-add-dimensions' output and (2) your edit of that output. | 13:21 |
| kanzure | diff (1) gxml-add-dimensions output and (2) darwin's saved version of #1. | 13:21 |
| kanzure | diff (1) your-edited-version and (2) darwin's saved version of #1 | 13:21 |
| kanzure | anyway, most important is whether or not newton's svn up'd version is capable of successfully loading your unix hand-edited version of the gxml-add-dimensions output. | 13:22 |
| fenn | ok, file from minsky loads on newton | 13:23 |
| kanzure | the universe is well again. | 13:24 |

| kanzure | thank you | 14:14 |
| fenn | hm that's not the page i was thinking of | 14:14 |
| kanzure | I find it funny that people on an open source project are asking "why do we want to use revision control! bah!" | 14:18 |
| kanzure | how sad is that | 14:18 |
| kanzure | as if open source projects happen in other ways? | 14:18 |
| fenn | up til a couple years ago almost all open source software was written by wise old unix hackers (well maybe not old) | 14:19 |
| fenn | but things are changing | 14:19 |
| kanzure | how is it done now? | 14:19 |

| fenn | i mean you cant expect people to know something they dont know | 14:20 |
| kanzure | that's fine | 14:20 |
| kanzure | but they shouldn't stop me from getting real work done | 14:20 |
| fenn | btw we should add .svnignore for all the bin/ and .dll files | 14:20 |
| kanzure | just because they're idiots. | 14:20 |
| kanzure | fenn: that's fine, go ahead | 14:20 |
| fenn | as it is i think svn tries to merge then (yeesh) | 14:21 |
| fenn | huh there is no such thing as a .svnignore file? | 14:26 |

| kanzure | my reply to that was something about how biohackers might need to be more than just biologists | 14:41 |
| kanzure | maybe it's possible that successful biohackers will need to be even more hackful than the original hackers | 14:41 |
| fenn | yeah, whatever that means | 14:42 |
| kanzure | er, sarcasm? | 14:42 |
| fenn | no i just dont know what it's supposed to mean | 14:42 |

| kanzure | I mean, how is that ahead of yourself? | 20:47 |

| kanzure | you're just.. going around or something | 20:48 |
| ybit | something like that :P | 20:48 |

| ybit | so you avoid spin coating? | 20:49 |
| kanzure | like I said, I've been avoiding it all my life | 20:49 |
| kanzure | maybe you know what it is | 20:49 |
| kanzure | you don't just spin something and make an even layer of something on it, eh? | 20:49 |
| ybit | only what wikipedia tells me | 20:49 |
| ybit | http://en.wikipedia.org/wiki/Spin_coating | 20:49 |
| ybit | right, that's essentially it | 20:50 |
| kanzure | does a CDROM drive count as a spin coater? | 20:50 |
| ybit | hmm | 20:51 |
| ybit | "Photoresist is typically spun at 20 to 80 Hz for 30 to 60 seconds." | 20:51 |
| kanzure | wait, is that all? | 20:52 |
| kanzure | not kHz or GHz or anything ridiculous? | 20:52 |
| ybit | uring the first stage, the plate is spun at a low to moderate speed 500-1000 rpm for 5-10 seconds to evenly spread the solution. The thickness of the coating is then determined and controlled during the second stage by spinning the coating at a higher speed, between 1500-3000 rpm for anywhere between a few seconds and a minute. These conditions will typically produce high quality coatings of thickness between 2 and 10 micrometres. | 20:52 |

Although microfluidic systems are convenient platforms for biological assays, their use in the life sciences is still limited mainly due to the high-level fabrication expertise required for construction. This approach involves prefabrication of individual microfluidic assembly blocks (MABs) in PDMS that can be readily assembled to form microflui | 22:34 |

| ybit | etching using leds, hmm | 23:05 |
| ybit | nope, dillusioned, sleep-deprived reading | 23:10 |
| ybit | helium etching on leds :) | 23:11 |
| ybit | helium plasma* | 23:11 |
| ybit | yup and i'm spent | 23:19 |
| * ybit makes it a point to read Intro to Microfabrication tomorrow | 23:20 | |
| kanzure | stop quoting Austin Powers | 23:20 |
