| kanzure | inbox down from 89,000 to 51,206 | 12:38 |
| kanzure | http://en.wikipedia.org/wiki/RNA_interference | 13:02 |
| kanzure | that's a very well cited article. 142 references. | 13:02 |
| kanzure | s/cited/referenced/ | 13:02 |
| kanzure- | http://www.columbia.edu/~jpl2136/zotfile.html Zotero Plugin to automatically rename, move, and attach pdfs (or other) files to Zotero items by pressing a button. | 13:11 |
| kanzure- | http://www.box.net/shared/ot1jp9obk6 ZoteroRename.02.py - renames PDFs to be something reasonable in zotero | 13:18 |
| kanzure- | oh, it's just an sqlite database | 13:20 |
| katsmeow-afk | mplayer plays 4 frames then also quits | 13:24 |
| katsmeow-afk | oops | 13:24 |
| kanzure- | http://heybryan.org/mediawiki/index.php?title=DNA_synthesizer_on_a_chip&action=history | 13:26 |
| kanzure- | huh. | 13:26 |
| kanzure- | august 2008? | 13:27 |
| kanzure | may 18, jocelyn is coming in to town to do some interviews with austin people in here | 16:48 |
| splicer | who is jocelyn? | 17:20 |
| kanzure | some reporter | 17:22 |
| splicer | zuckerman? | 17:22 |
| kanzure | yes | 17:27 |
| -!- PeerInfinity [n=someone@216.36.180.162] has joined #hplusroadmap | 17:30 | |
| kanzure- | archives of RDF bibliographies plus the PDFs are now on the server | 19:38 |
| kanzure- | http://heybryan.org/books/papers/bibliographies/ | 19:38 |
| kanzure- | they are the .tar.gz files | 19:38 |
| kanzure- | most useful for importing into zotero in firefox, but maybe there's another way to make use of the files | 19:38 |
| -!- fenn [n=fenn@cpe-72-177-52-180.austin.res.rr.com] has joined #hplusroadmap | 20:03 | |
| kanzure- | hi fenn. | 20:08 |
| fenn | hrmph. capaciflector maximum range is 0.5" for typical designs and 1 ft for specialized versions | 20:13 |
| kanzure- | so I wasn't understanding that entirely. why would you want to visualize only a single point source of ionizing radiation? | 20:14 |
| fenn | i could think of lots of uses if it worked as he described (range > 1ft) | 20:16 |
| fenn | for instance when you spill some radioactive stuff and then track it around on the floor | 20:16 |
| fenn | takes for ever to find it all with a geiger counter | 20:16 |
| fenn | course i dont understand how his radioscope would work anyway.. since the ionization cascade in a geiger tube is like a big cone | 20:17 |
| kanzure- | did you take down hologram-guy's name | 20:18 |
| kanzure- | or mr "blows les out of the water" I guess | 20:18 |
| fenn | the tech guy at texas state? | 20:18 |
| kanzure- | yes | 20:18 |
| fenn | yeah | 20:19 |
| kanzure- | after looking over the list, there was no machining stuff | 20:19 |
| kanzure- | it was mostly just scientific instrumention | 20:19 |
| kanzure- | *instrumentation | 20:19 |
| kanzure- | but he was talking about machining tools | 20:19 |
| fenn | dan millican, km03@txstate.edu | 20:19 |
| kanzure- | guess I now know the type of person to try to find more of now. people who manage a university's scientific instrumentation. | 20:25 |
| fenn | "Since every material has a unique permittivity, an object can be identified by scanning its permittivity curves vs. frequency information and matching its identity to that stored in a database." | 20:25 |
| fenn | yeah i always admired lab techs | 20:25 |
| fenn | the guy that makes it all possible :) | 20:26 |
| fenn | permittivity -> frequency could be translated to a color spectrum to be applied as a shader to the 3D capacitance field measurement | 20:27 |
| kanzure- | if you're finding any papers or something, links would be nice | 20:29 |
| kanzure- | rather than random sourceless quotes :p | 20:29 |
| fenn | bah | 20:29 |
| kanzure- | bah humbug | 20:29 |
| fenn | papers are 99% useless | 20:29 |
| kanzure- | true that. | 20:29 |
| fenn | http://www.nasamike.com/main/roboticslab/technologies.html | 20:29 |
| fenn | i just followed links from the first google hit | 20:30 |
| fenn | http://ranier.hq.nasa.gov/telerobotics_page/Technologies/0266.html | 20:30 |
| fenn | http://www.solarbotics.net/library/pieces/assy_sensors_field.html#capaciflector | 20:30 |
| fenn | so there | 20:30 |
| fenn | now you have enough info to make one | 20:31 |
| kanzure- | http://heybryan.org/books/papers/bibliographies/ I added .tar.gz files that include bibliographies plus PDFs, btw. it's in some weird RDF format. importing into zotero is the only way to make use of it at the moment. | 20:31 |
| kanzure- | yay. | 20:31 |
| kanzure- | but I still don't understand it. is the goal to get a 2D visualization of a radiation pattern, like a spill? | 20:31 |
| fenn | i don't know or care what that guy's goal is | 20:31 |
| fenn | since i can't understand it from first principles and he can't explain it, why bother | 20:32 |
| kanzure- | but then what does it *do* | 20:32 |
| kanzure- | ah | 20:32 |
| kanzure- | ok, so everyone is just as confused as I am | 20:32 |
| kanzure- | in firefox, why doesn't "view source" work for URIs like chrome://browser/content/bookmarks/bookmarksPanel.xul | 20:33 |
| kanzure- | I don't want to go unjar the file. blah. | 20:33 |
| fenn | i think motorola made a capaciflector-y sensor to detect the position of infants in a car seat | 20:37 |
| fenn | fun page to look at http://techtransfer.gsfc.nasa.gov/technologies.html | 20:41 |
| fenn | i wonder what happens to technologies that have been patented by nasa employees | 20:41 |
| kanzure- | they quit and then get hired again as a contractor with a contract paying 10x more | 20:42 |
| fenn | but still the patent was developed while employed at a government agency | 20:46 |
| kanzure- | "national secret" | 20:47 |
| fenn | i wish i knew what the hell this was about http://techtransfer.gsfc.nasa.gov/ft-tech-gear-bearings.html | 20:48 |
| katsmeow-afk | http://techtransfer.gsfc.nasa.gov/images/GB-roller-gear2.jpg explains it | 20:54 |
| kanzure- | gene's been trying to reverse engineer those actually | 20:54 |
| fenn | i don't get the 'rifle true anti-backlash' | 20:55 |
| fenn | obviously those are spur gears, so how could it be rifled? | 20:55 |
| fenn | (no i'm not being dense) | 20:55 |
| kanzure- | apparently treadwell is meeting lunch for les tomorrow at 1 pm | 20:56 |
| kanzure- | he asked if I wanted to come along and get lunch with him. | 20:56 |
| katsmeow-afk | it's a metaphor, it's not rifled | 20:56 |
| kanzure- | I don't know if I want to go through les' whole spiell again. I could be more useful sitting around at home programming | 20:56 |
| kanzure- | although it is free food. hrm. | 20:56 |
| katsmeow-afk | i have seen gearboxes where the input gearshaft floats free in the carrier gears | 20:57 |
| katsmeow-afk | and as for the 2000:1 reduction ratio, most chinese winches use a 2-tooth offset and two ring gears to get huge gear ratios | 20:58 |
| kanzure- | there are these diagrams where I see gears inside of a circle | 20:58 |
| kanzure- | a "gear within a gear" | 20:58 |
| kanzure- | is that what this is about? | 20:58 |
| fenn | why 2-tooth and not just 1-tooth/ | 20:58 |
| fenn | kanzure-: no | 20:58 |
| katsmeow-afk | in theory, this paper describes a perfectly machined gearset, but how to make it is a different story | 20:59 |
| fenn | no, otherwise they wouldn't need an anti-backlash mechanism | 20:59 |
| katsmeow-afk | well, the antibacklash is for the way teeth meet differently, and wear difefrently, as they move past each other | 20:59 |
| katsmeow-afk | by using a 50% phase offset, you have mid-tooth to mid-tooth as well as tooth-tip to tooth-root happening at the same time | 21:00 |
| fenn | ok that sounds like a reasonable explanation | 21:00 |
| katsmeow-afk | if you herrinbone them, one gearset will be pulling one way with torque applied, the otehr set herererngboned int he opposite dir will pull the otehr way | 21:01 |
| katsmeow-afk | the combination tends to take up all the slack, and screw up mechanicnal harmonics so it runs with less vibration, they claim | 21:02 |
| katsmeow-afk | i suspect each roller-gear may need to be made as 3 pieces, complicating how true the gear part vs roller part are aligned, etc | 21:03 |
| katsmeow-afk | as you can see in http://techtransfer.gsfc.nasa.gov/ft-tech-gearbearings-animation.html , it's a normal planetary system, with rollers applied, and herringbones, and offset parallel gearsets, etc etc | 21:04 |
| drazak | yo guys | 21:05 |
| drazak | have any of you seen this flu thing? | 21:05 |
| katsmeow-afk | swine + bird + human flu? | 21:06 |
| katsmeow-afk | no | 21:06 |
| fenn | i guess i can't play that animation | 21:06 |
| drazak | well | 21:06 |
| drazak | it would be a great thing for diybio to get involved in | 21:06 |
| drazak | if they got organized | 21:06 |
| katsmeow-afk | fenn, it's a plain ordinary planetary gear box, and jerky and poorly made,, it shows only the addition of the rolelrs at the ends of the gears | 21:06 |
| kanzure- | drazak: what? | 21:08 |
| drazak | kanzure-: well, if some of diybio had their stuff together yet, they could start working on the treatment/analysis of this new flu thing | 21:09 |
| kanzure- | new flu? | 21:09 |
| drazak | aye | 21:09 |
| kanzure- | what's wrong with the old flu? | 21:09 |
| drazak | in new mexico | 21:09 |
| drazak | http://www.eleconomista.es/empresas-finanzas/noticias/1193372/04/09/Fatal-swine-flu-breaks-out-in-Mexico.html | 21:09 |
| drazak | er, in mexico | 21:09 |
| katsmeow-afk | tis been spotted in the usa too | 21:10 |
| drazak | yeah | 21:11 |
| drazak | the only problem is with actually handling hazardous samples | 21:11 |
| drazak | most people would need actual lab training for that | 21:11 |
| kanzure- | programming for firefox is mostly just hunting down XUL/GUI stuff. this isn't fun. | 21:50 |
| fenn | i wish i could zoom in to gdmap with a scroll wheel and see tiny preview images | 22:13 |
| fenn | as it is right now, when you double-click to move to a new level, everything gets scrambled | 22:14 |
| fenn | really now, it's 2009 and there are _still_ no zooming file managers? | 22:17 |
| kanzure- | wait, it gets scrambled? | 22:19 |
| kanzure- | I don't remember that. | 22:19 |
| kanzure- | konqueror and some other apps have somewhat of a preview mode of some sort or another | 22:20 |
| kanzure- | you might want to see how they generate those pictures | 22:20 |
| kanzure- | and then map those as textures to rectangular blocks in some opengl mode that imitates gdmap | 22:20 |
| kanzure- | since gdmap is basically just parsing some shell results more than anything else. | 22:20 |
| fenn | yes konqueror preview works great but only at one level of hierarchy at a time (as far as i can tell) | 22:22 |
| fenn | i'd probably do a lot of things differently than gdmap does anyway | 22:22 |
| fenn | extending fsv seems like the logical choice | 22:22 |
| kanzure- | there's a 3d file viewer but you were the one who told me about it, so nevermind | 22:23 |
| fenn | http://fsv.sourceforge.net/screenshots/06.png | 22:23 |
| fenn | add textures and voila | 22:24 |
| kanzure- | depends. they might be doing something custom/stupid for 3D stuff. | 22:24 |
| fenn | pretty sure it's opengl | 22:24 |
| fenn | someone needs to tell these guys about graph layout algorithms http://fsv.sourceforge.net/screenshots/12.png | 22:25 |
| kanzure- | how would thumbnails help anyway? | 22:25 |
| kanzure- | that's not a bad algorithm though | 22:25 |
| kanzure- | er, I'm not sure what's going on though | 22:25 |
| fenn | it's bad because you can barely fit anything on the screen at once | 22:25 |
| fenn | i mean, maybe if you had a really long skinny screen | 22:26 |
| kanzure- | heh, accelerometers hooked up to a head tilt for 3D file viewing | 22:28 |
| kanzure- | useless though. | 22:29 |
| kanzure- | "if you tilt your head just right, your file suddenly becomes apparent" | 22:29 |
| fenn | not useless | 22:31 |
| fenn | that's exactly what i'm planning on, actually | 22:31 |
| fenn | not like flipping through a book.. remember the hyperbolic transform (is that what it was called?) | 22:32 |
| kanzure- | no. | 22:32 |
| kanzure- | it might be nice to map head gestures to shortcuts I guess | 22:33 |
| fenn | conformal mapping maybe is what i'm thinking? http://www.flickr.com/photos/sbprzd/sets/72157594172266668/ | 22:33 |
| fenn | that's the opposite what you want for a mobile head-tracking app though | 22:34 |
| kanzure- | did I show you that program thingy that takes string grammars and makes beautiful graphs? | 22:34 |
| kanzure- | something showing simple grammars and generating ridiculously awesome graphs | 22:34 |
| fenn | oh maybe i am thinking hyperbolic mapping: http://neurovia.umn.edu/home/kelly/BPhySem99/angel_w.gif | 22:35 |
| fenn | stupid words | 22:35 |
| fenn | what is a 'string grammar'? | 22:36 |
| kanzure- | a list of things to do in sequential order | 22:37 |

| -!- fenn_ is now known as fenn | 22:44 | |
| fenn | man i love this stuff, why can't we have more user interfaces like this? http://www.davemc.net/GenArt/Gallery/ | 22:45 |
| fenn | except the parameters would be real meaningful values blah blah blah | 22:45 |
| kanzure- | "genetic art" brings new meaning to "high class art". damn genetic elitists. | 22:46 |
| fenn | looks like disk fragmentation http://www.davemc.net/GenArt/Gallery/images/g00776340.jpg | 22:47 |
| fenn | know any good tools for merging (possibly) forked filesystems? | 22:55 |
| fenn | for example i have a dir with pdf's on the laptop and i try to 'archive' them on the desktop | 22:55 |
| fenn | i'd like to copy the folder over and compare to see what's already in the hierarchy somewhere | 22:56 |
| fenn | seems shell doesn't lend itself to 'set operations' very well | 22:56 |
| fenn | maybe i'm just spoiled | 22:56 |
| kanzure | http://arxiv.org/abs/0904.2625 | 22:59 |
| kanzure | finding out how long RNA polymerase spends at each monomer base | 22:59 |
| kanzure | fenn: rsync? | 22:59 |
| kanzure | or maybe some sort of tar-related tool | 22:59 |
| kanzure | if you just want to compare hierarchy file names, I have a script for that. /me digs | 23:00 |
| fenn | rsync wants a network connection and client/server which is just silly (since all this is on a local filesystem) | 23:00 |
| kanzure | http://heybryan.org/~bbishop/docs/scripts/tree2 | 23:00 |
| kanzure | or possibly this one: http://heybryan.org/~bbishop/docs/scripts/tree | 23:00 |
| fenn | uhm.. are you aware of the 'tree' command? | 23:00 |
| kanzure | uhh | 23:00 |
| kanzure | fuck | 23:00 |
| kanzure | "tree: command not found" | 23:01 |
| fenn | ls -R is good; didnt want to have to split up path/filename | 23:01 |
| fenn | tree is a debian package | 23:02 |
| kanzure | oh, btw, before I forget, jocelyn, some NYC reporter wants to come down next month | 23:09 |
| kanzure | around the 18th, to talk with diybio people | 23:09 |
| fenn | um, all three of us? | 23:11 |
| fenn | i mean, i just post to a mailing list occasionally.. that's hardly newsworthy | 23:11 |
| kanzure | what is "newsworthy"? | 23:12 |
| kanzure | gah, that sounds philosophical but it's not, it's a genuine question | 23:13 |
| kanzure | there's at least four I count here, btw. | 23:13 |
| fenn | antony (?) drazak, you, splicer ... anyone else? | 23:14 |
| drazak | yo | 23:14 |
| kanzure | what? | 23:14 |
| kanzure | they aren't local | 23:14 |
| fenn | er, yeah. | 23:14 |
| kanzure | you, me, gene, cline. | 23:14 |
| kanzure | four locals. | 23:14 |
| * fenn is suffering from a chocolate deficiency | 23:15 | |
| fenn | you can see where my thought process derailed | 23:15 |
| kanzure | yes | 23:15 |
| kanzure | but it's still funny. | 23:16 |
| fenn | does gene follow diybio? | 23:16 |
| kanzure | he's definitely on the list | 23:16 |
| kanzure | but he doesn't do much following to my knowledge | 23:16 |
| kanzure | so I got the plugin to "work" somewhat | 23:17 |

| kanzure | wow. I did this? http://heybryan.org/projects/calxism/my.xul | 23:19 |
| kanzure | hahah. that's right.. this is the "chat thingy in a browser" | 23:20 |
| -!- genehacker [n=chatzill@wireless-128-62-98-195.public.utexas.edu] has joined #hplusroadmap | 23:21 | |
| kanzure | the search assistant is just meant to keep track of searching more than anything at first | 23:21 |
| kanzure | and then eventually also automagical search term permutation | 23:21 |
| kanzure | ideally this is something that google should already be doing. but it's not done. | 23:22 |
| kanzure | for instance, I find myself doing 5-word queries and then changing one word somehow, and then permutating the query in another way | 23:23 |
| kanzure | and then loosing track of the hierarchy of changes or something | 23:23 |
| kanzure | because there are certain routes that I was going to explore at some later time but then completely forgot about | 23:23 |
| kanzure | because the tree/stack is too large for me to mentally remember | 23:23 |
| fenn | the traditional solution to this problem is to get some graduate students | 23:26 |
