16:48 < kanzure> may 18, jocelyn is coming in to town to do some interviews with austin people in here
17:20 < splicer> who is jocelyn?
17:22 < kanzure> some reporter
17:22 < splicer> zuckerman?
17:27 < kanzure> yes
17:30 -!- PeerInfinity [n=someone@216.36.180.162] has joined #hplusroadmap
19:38 < 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
20:03 -!- fenn [n=fenn@cpe-72-177-52-180.austin.res.rr.com] has joined #hplusroadmap
20:08 < kanzure-> hi fenn.
20:13 < fenn> hrmph. capaciflector maximum range is 0.5" for typical designs and 1 ft for specialized versions
20:14 < kanzure-> so I wasn't understanding that entirely. why would you want to visualize only a single point source of ionizing radiation?
20:16 < 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
20:17 < fenn> course i dont understand how his radioscope would work anyway.. since the ionization cascade in a geiger tube is like a big cone
20:18 < 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
20:19 < 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
20:25 < 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
20:26 < fenn> the guy that makes it all possible :)
20:27 < fenn> permittivity -> frequency could be translated to a color spectrum to be applied as a shader to the 3D capacitance field measurement
20:29 < 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
20:30 < 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
20:31 < 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
20:32 < 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
20:33 < 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.
20:37 < fenn> i think motorola made a capaciflector-y sensor to detect the position of infants in a car seat
20:41 < 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
20:42 < kanzure-> they quit and then get hired again as a contractor with a contract paying 10x more
20:46 < fenn> but still the patent was developed while employed at a government agency
20:47 < kanzure-> "national secret"
20:48 < fenn> i wish i knew what the hell this was about http://techtransfer.gsfc.nasa.gov/ft-tech-gear-bearings.html
20:54 < 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
20:55 < 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)
20:56 < 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.
20:57 < katsmeow-afk> i have seen gearboxes where the input gearshaft floats free in the carrier gears
20:58 < 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
20:59 < 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
21:00 < 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
21:01 < 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
21:02 < katsmeow-afk> the combination tends to take up all the slack, and screw up mechanicnal harmonics so it runs with less vibration, they claim
21:03 < 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
21:04 < 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
21:05 < drazak> yo guys
21:05 < drazak> have any of you seen this flu thing?
21:06 < 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
21:08 < kanzure-> drazak: what?
21:09 < 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
21:10 < katsmeow-afk> tis been spotted in the usa too
21:11 < 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
21:50 < kanzure-> programming for firefox is mostly just hunting down XUL/GUI stuff. this isn't fun.
22:13 < fenn> i wish i could zoom in to gdmap with a scroll wheel and see tiny preview images
22:14 < fenn> as it is right now, when you double-click to move to a new level, everything gets scrambled
22:17 < fenn> really now, it's 2009 and there are _still_ no zooming file managers?
22:19 < kanzure-> wait, it gets scrambled?
22:19 < kanzure-> I don't remember that.
22:20 < 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.
22:22 < 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
22:23 < 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
22:24 < 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
22:25 < 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
22:26 < fenn> i mean, maybe if you had a really long skinny screen
22:28 < kanzure-> heh, accelerometers hooked up to a head tilt for 3D file viewing
22:29 < kanzure-> useless though.
22:29 < kanzure-> "if you tilt your head just right, your file suddenly becomes apparent"
22:31 < fenn> not useless
22:31 < fenn> that's exactly what i'm planning on, actually
22:32 < fenn> not like flipping through a book.. remember the hyperbolic transform (is that what it was called?)
22:32 < kanzure-> no.
22:33 < 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/
22:34 < 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
22:35 < fenn> oh maybe i am thinking hyperbolic mapping: http://neurovia.umn.edu/home/kelly/BPhySem99/angel_w.gif
22:35 < fenn> stupid words
22:36 < fenn> what is a 'string grammar'?
22:37 < kanzure-> a list of things to do in sequential order

22:44 -!- fenn_ is now known as fenn
22:45 < 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
22:46 < kanzure-> "genetic art" brings new meaning to "high class art". damn genetic elitists.
22:47 < fenn> looks like disk fragmentation http://www.davemc.net/GenArt/Gallery/images/g00776340.jpg
22:55 < 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
22:56 < 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
22:59 < 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
23:00 < 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
23:01 < kanzure> "tree: command not found"
23:01 < fenn> ls -R is good; didnt want to have to split up path/filename
23:02 < fenn> tree is a debian package
23:09 < 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
23:11 < fenn> um, all three of us?
23:11 < fenn> i mean, i just post to a mailing list occasionally.. that's hardly newsworthy
23:12 < kanzure> what is "newsworthy"?
23:13 < 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.
23:14 < 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.
23:15  * fenn is suffering from a chocolate deficiency
23:15 < fenn> you can see where my thought process derailed
23:15 < kanzure> yes
23:16 < 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
23:17 < kanzure> so I got the plugin to "work" somewhat

23:18 < kanzure> s/plugin/extension/
23:19 < fenn> what sort of plugin are you writing?
23:19 < kanzure> google scholar search assistant
23:19 < kanzure> wow. I did this? http://heybryan.org/projects/calxism/my.xul
23:20 < kanzure> hahah. that's right.. this is the "chat thingy in a browser"
23:21 -!- 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
23:22 < kanzure> ideally this is something that google should already be doing. but it's not done.
23:23 < 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
23:26 < fenn> the traditional solution to this problem is to get some graduate students
