| kanzure | xp_prg: I saw John's announcement, if that's what you mean | 00:04 |
| xp_prg | ya | 00:04 |
| xp_prg | VA = virignia | 00:04 |
| xp_prg | kanzure I am going to put in an app, may I mention our work together? | 00:04 |
| kanzure | I'd have trouble getting up there. | 00:04 |
| kanzure | xp_prg: Only if you run it by me first. | 00:04 |
| xp_prg | they are paying for transportation | 00:04 |
| kanzure | I don't think you know the entire system yet. | 00:04 |
| xp_prg | ok | 00:05 |
| kanzure | ybit: You should tell him that. | 00:31 |
| kanzure | ybit: Seriously. I don't know why he doesn't idle in here. | 00:31 |
| kanzure | It's not like it would hurt him. | 00:31 |
| kanzure | Arrgh! The pain! Moderately relevant topics! | 00:31 |
| -!- mmarmer_ is now known as mmarmer | 00:34 | |
| kanzure | Hi mmarmer. | 00:34 |
| mmarmer | hey | 00:34 |
| kanzure_ | http://www.artas.nl/ [commercial link] User-friendly software for design, motion/force analysis & optimization of planar linkage, gear and belt mechanisms | 00:54 |
| kanzure_ | Designers will synthesize a linkage by starting with the required output motion, mechanical advantage, velocity and acceleration. A type of linkage is chosen and modified to deliver the required performance. | 00:56 |
| kanzure_ | Each link is treated as a vector and the vectors can be combined into a system of equations because they form a loop. The matrix is solved to create a closed form equation that relates input motion to output motion. The same is done for mechanical advantage, or any other important quantity. The equations of motion are differentiated with respect to time to find velocity and acceleration of the mechanism parts. | 00:56 |

| kanzure_ | http://www.youtube.com/watch?v=b0I65dJMQUc&NR=1 blender tutorial - theo jansen mechanism | 01:01 |
| kanzure_ | http://www.youtube.com/watch?v=JoQj-tobYOw&feature=related wheel-less bicycle. :) | 01:02 |
| kanzure | hm, if I had a GA or other search algorithm for making bar/linked mechanisms with various degrees of freedom, how would you prevent it from just converging on the shape of a circle? I'm imagining a simualtor where you apply a force and try to see how far it goes or something | 01:05 |
| kanzure | I guess it's a question of what to optimize for - diversity of generated designs to solving the same problem? That might be a sufficient metric. | 01:05 |
| fenn | how does it steer? | 01:06 |
| kanzure | "I've invented a brilliant bicycle that doesn't use wheels. The only downside is that it only goes in one direction. Good luck." | 01:07 |
| kanzure | hehe | 01:07 |
| fenn | i know the strandbeest could steer somehow to keep it on the beach | 01:08 |
| kanzure | I don't remember what its overall shape was, was this just the linear one like a centipede? | 01:09 |
| kanzure | and then it would use the pressure sensors made out of its feet to go in opposite directions with some internal logic | 01:09 |
| kanzure | so it might have been a circular design or something | 01:09 |
| kanzure | with eight legs or something. | 01:09 |
| kanzure | eight "chunks" of legs. | 01:09 |
| kanzure | so eight directions I guess. | 01:10 |
| kanzure | hrm. | 01:13 |
| kanzure | That's odd. | 01:13 |
| kanzure | Anyway, is this stuff anything more than just bars and joints? | 01:15 |
| fenn | no | 01:18 |
| kanzure | can you braindump a list of calculations that should be associated with these? | 01:19 |
| kanzure | it shouldn't be hard for me to make up some objects somewhere and then randomly connect them and try them out. don't know why ADL has an entire person working on this. | 01:19 |
| kanzure | I wonder if there's an interactive gnuplot for python dealy out there yet. | 01:22 |
| ybit | some local is going to give me a few G3s, netvista machines, monitors, and keyboards. i <3 freecycle | 01:38 |
| kanzure | Yep. | 01:38 |
| ybit | http://www.vmunix.com/mark/blog/archives/2008/10/17/cloud-computing-is-a-sea-change-how-sysadmins-can-prepare/ | 01:39 |
| kanzure | Oh, I'm getting access to a moderate sized cluster soon. | 01:39 |
| ybit | what is moderate? | 01:40 |
| kanzure | Not super. | 01:40 |
| ybit | heh :P | 01:40 |
| * ybit wants more details | 01:40 | |
| ybit | aside from "not quite super, not quite negligible" | 01:41 |
| kanzure | I'll get you the details when I get them. | 01:41 |
| ybit | okey | 01:41 |
| ybit | this guy told me to bring a pickup and take as many machines as i wanted, he bought hundreds at a recent auction o.O | 01:41 |
| kanzure | It looks like for mechanical kinematics all I'd have to do is encode degrees of freedom constraints | 01:41 |
| kanzure | heh | 01:41 |
| kanzure | Yeah, I met a guy like that, didn't go up to his house though | 01:42 |
| kanzure | he was a freecycler somewhere up in North Texas and basically has old AT terminals in giant junk piles on a few acres | 01:42 |
| kanzure | does a lot of 'research' on his own time, that sort of thing | 01:42 |
| kanzure | Can't get him oline because of poor eyesight apparently. | 01:42 |
| kanzure | Bill Snodgrass, I think. | 01:43 |
| fenn | parallel kinematics gets ugly quick | 01:47 |
| fenn | sometimes there isn't a direct analytical transformation from joint space to cartesian space | 01:47 |
| kanzure | oh? | 01:47 |
| fenn | hmm. somehow i find it hard to take statements like this seriously: | 01:50 |
| fenn | "That's right, as an industry we're truly about to automate ourselves out of our jobs. Which, of course, is what we've been nobly aspiring to do for 30 years, but, folks, this time we're actually going to do it" | 01:50 |
| kanzure | source? | 01:51 |
| fenn | ybit's link | 01:52 |
| fenn | cloud-computing-will-kill-us-all | 01:52 |
| kanzure | so what's so hard about this kinematics stuff | 01:52 |
| fenn | dunno | 01:52 |
| kanzure | I mean, when I look at it, it's like animation skeletons for video games | 01:52 |
| fenn | that's not parallel links | 01:53 |
| ybit | fenn, he says there are other tasks that sysadmins will be performing | 01:53 |
| kanzure | what's a parallel link? | 01:53 |
| ybit | not the ones typically performed today | 01:53 |
| fenn | well, like theo janssen mechanism has two parallel links | 01:53 |
| fenn | er, two links in parallel | 01:53 |
| kanzure | so just a rectangle. | 01:54 |
| fenn | the stewart platform (hexapod) is another parallel topology | 01:54 |
| fenn | your neck uses parallel linkage | 01:54 |
| kanzure | what's the linking mechanism? | 01:54 |
| fenn | muscles | 01:54 |
| kanzure | no, in let's say the theo janssen mechanism | 01:55 |
| fenn | oh, pins and bearings i guess | 01:55 |
| kanzure | so what's hard about doing that taking analogies from animation skeletons | 01:55 |
| fenn | doesn't really matter for the purposes of calculating where it will be given a certain pose | 01:55 |
| kanzure | again, degrees of freedom. those linkers being highly constrained of course. | 01:56 |
| fenn | "why is anything hard" | 01:56 |
| kanzure | well I guess there's some hardness in figuring out how to draw interesting things out of these beams, Hod had a lot of video clips of things that didn't even barely flo | 01:57 |
| kanzure | flop | 01:58 |
| kanzure | and they were using some internal linear actuators | 01:58 |
| kanzure | I guess a 'hard' part about such generators for these mechanism designs would be to make sure that parallel structures crop up at some frequency, rather than allowing a full range of irrational numbers to specify placement coords | 02:01 |
| kanzure | although presumably all patterns can be broken down into simpler more fundamental patterns, right? and that's just a single bar, no? | 02:01 |
| fenn | how many foglets could a foglet chuck | 02:04 |
| wrldpc | anyone have that open currency link fenn posted earlier? | 03:08 |
| wrldpc | I think it was fenn .. | 03:08 |
| fenn | wrldpc: http://openmoney.info/sophia/index.html http://evolvingtrends.wordpress.com/2008/10/21/p2p-social-currency-money-20/ probably one of those | 04:37 |
| wrldpc | ty | 04:37 |
| fenn | i'm rather against calling it "currency" or "money" since there are too many preconceived notions about what money is already | 04:37 |
| fenn | and it's too easy to just say "money sucks" without providing any solutions | 04:38 |
| kanzure | blah, now I'm hooked on figuring out how to pull off a koyaanisqatsi for manufacturing. It's so easy with classical music + trance paired to random hypnotizing shots. | 04:40 |
| kanzure | "look, a spinny thinger" | 04:41 |
| fenn | a lot of "industrial" music came from people using sampled sounds of machinery | 04:50 |
| fenn | would be neat to do some sort of video sequencing where you see it and hear it at the same time | 04:51 |
| kanzure | so when I heard about Black Sabbath and the finger accident, I thought it was kind of cool that they went on to do metal | 04:51 |
| kanzure | but then I realized it was just a finger | 04:51 |
| kanzure | people lose half their bodies, most of their brains, etc. | 04:51 |
| kanzure | where's *their* heavy metal? :/ | 04:51 |
| fenn | heh maybe you should just start recruiting brain damaged people to play music | 04:53 |
| kanzure_ | "You could be the first on your block to own a residual gas analyzer which has an open filament in the ion source. Replacement filaments are available for $485 and I do not wish to spend this much to repair the instrument." | 05:16 |
| kanzure_ | freecycle contact I think | 05:16 |
| fenn | hmm how much could some tungsten wire cost | 05:18 |
| fenn | still that's not a bad price for a working mass spec. | 05:20 |
| kanzure | what, free? :) | 05:21 |
| kanzure | why is it that I get equipment when I least need it / least have room for it | 05:21 |
| kanzure | this is silly. we have excellent mass spec machines on campus | 05:21 |
| kanzure | and no room in a dorm | 05:21 |
| kanzure | where's the bryanlab when I need it | 05:21 |
| fenn | how big is it? | 05:21 |
| kanzure | dunno, I've asked though | 05:21 |
| fenn | some pics on the intarweb look lunchbox sized | 05:22 |
| fenn | of course it would be sorta useless without a high vacuum system | 05:24 |
| fenn | http://www.pascaltechnologies.com/Products/SpecialThumbs/Complete_XTx00big.jpg | 05:24 |
| fenn | "glow discharge between the quadrupole rods is the main limit to high pressure operation, not the mean free path length of the residual gas molecules, so they have roughly the same high pressure operating limit. Operation at high pressures will result in a very short filament life also." | 05:27 |

| kanzure | I used to be one of the occupants of 4chan. :/ | 13:54 |
| wrldpc | So did I .. for like a noncontiguous week. | 13:55 |
| kanzure | I was so excited when I learned that there was another 4channer in my high school when I was a freshman. Ah, those were the days. | 13:55 |

| wrldpc | If they had any real skills and any real intelligence (yes, intelligence) they would hijack the Super Bowl broadcast this year and transmit a neo bla bla bla | 13:57 |
| wrldpc | tetris is nice .. | 13:57 |

| kanzure | I'm amazed that people who run television networks still know how to do "live" footage. | 14:01 |
| wrldpc | why isn't there anyone out there with robust spam technologies filling everyone's email box with the H+ memes? | 14:01 |
| kanzure | Why would that be productive? | 14:02 |
| kanzure | besides "male enhancement" spamvertisements | 14:02 |
| wrldpc | heh | 14:02 |
| wrldpc | it's very theoretical | 14:02 |
| wrldpc | the gist is ... the memes are like software the brains process ... | 14:02 |
| kanzure | Everybody always wants to do something to "help H+" but it always turns into some stupid publicity thingy. | 14:02 |
| wrldpc | more processors .. | 14:03 |
| kanzure | bullfucking shit | 14:03 |

| kanzure_ | http://www.pge.utexas.edu/faculty/srinivasan.cfmv <- Meeting with this guy today at 4 pm. Any suggestions? | 19:55 |
| xp_prg | nothing showed for me kanzure_ | 20:27 |
| kanzure | Where? | 20:27 |
| xp_prg | that link | 20:27 |
| kanzure | I probably added an extra v at the end. | 20:27 |
| xp_prg | I suggest you tell him synthetic biology is the future and "step off bitch" | 20:28 |
| kanzure | ?? | 20:28 |
| kanzure | What do you think he does? | 20:28 |
| xp_prg | Petroleum engineering | 20:29 |
| xp_prg | he works at stanford? | 20:29 |
| kanzure | And what do you think I do? | 20:29 |
| kanzure | biofuel bioreactors don't have the word fuel in it for nothing | 20:29 |
| kanzure | while it's not petro, I just don't see what you're getting at | 20:29 |
| kanzure | synthetic biology assists in variosu fuel scenarios, fyi | 20:29 |
| xp_prg | yes I know | 20:29 |
| xp_prg | tell him that | 20:29 |
| xp_prg | and then to "step off" | 20:30 |
| xp_prg | does that make sense kanzure? | 20:31 |
| kanzure | Not really. I don't understand, do you have a bias against petro people? | 20:32 |
| xp_prg | no, dude, making a joke | 20:32 |
| xp_prg | just trying to say synth bio is where its at | 20:32 |
| xp_prg | he probably doesn't understand its potential | 20:32 |
| kanzure_ | "Today, a Japanese startup called Lunascape has released an alpha version of its Lunascape browser... that allows you to switch between all three of these prominent rendering engines. The company says that the Japanese version of Lunascape has been downloaded 10 million times and touts it as the fastest browser available."" | 21:00 |
| kanzure_ | I wonder how they're managing to do that. I guess they either have backend deals with Microsoft, and some tie-in with Gecko, and webkit. | 21:00 |

| gene | blender huh? | 21:33 |
| kanzure_ | just showing that mechanical kinematic components have been done in blender. | 21:33 |
| gene | well the beauty of rigidchips isn't that you can make mechanical kinematic components, it's that you can quickly and easily make something with them that you can control | 21:36 |
| kanzure | why do you think I was comparing blender to rigidchips? | 21:36 |
| kanzure | I wasn't .. | 21:36 |
| gene | ok | 21:36 |
| kanzure | and also, it's not beauty because it's closed source and proprietary. | 21:36 |
| gene | I wouldn't exactly call it proprietary | 21:37 |
| gene | it's free | 21:37 |
| gene | neither is it open source | 21:37 |
| bkero | There's some pretty impressive stuff done in blender. | 21:38 |
| gene | though there is a resources folder with all the textures, basic model meshes and stuff like that | 21:39 |
| gene | there might be some other stuff in there too | 21:39 |
| gene | but I haven't really checked it out | 21:39 |

| bkero | This was done in Blender: http://downloads.sketchworkproductions.com/peach/big_buck_bunny_1080p_h264.mov | 21:39 |
| kanzure | ah yes the "open source movie" crazies :) | 21:39 |
| gene | I can't see it | 21:39 |

| kanzure_ | http://heybryan.org/bioreactor/membraneless_filtration/2008-11-25_something_wrong.png <- gnuplot stuff. | 21:43 |
| gene | End Sub | 21:43 |
| gene | would that be considered open source? | 21:43 |
| gene | if it includes what the code is? | 21:44 |
| bkero | No | 21:44 |
| UtopiahGHML | gene: http://paste-it.net/ | 21:44 |
| bkero | gene: If 'seeing the code' means it's open source, then all of php is inherently open source. | 21:44 |
| gene | this is in the documentation folder | 21:44 |
| kanzure_ | Anyway, what do you want to do with it gene? | 21:45 |
| gene | make it better | 21:45 |
| kanzure_ | do you expect me to use this Visual Basic code to do something? | 21:45 |
| kanzure_ | *source code | 21:45 |
| gene | NO | 21:45 |
| kanzure_ | CPE 3.118 apparently. | 21:45 |
| * kanzure_ leaves | 21:45 | |
| gene | bye | 21:45 |
| kanzure | I'm surprised. Sanjay knew about VTK and OpenFOAM and was quite enthusiastic about these two packages being used. | 23:07 |
| gene | kanzure? | 23:10 |
| kanzure_ | gene: apt-get install freefem3d ifrit libvtk5 libvtk5-dev mayavi mayavi2 octaviz python-vtk python-pyvtk vtk-doc vtk-examples vtk-tcl vtkdata | 23:10 |
| gene | hold on a second, I have to install linux | 23:10 |
| gene | are you serious? | 23:11 |
| kanzure_ | Yes, the packages really are useful. | 23:11 |
| gene | that's a lot | 23:11 |
| kanzure_ | it's like 566 MB of packages, so you should do it in the lab | 23:11 |
| kanzure_ | will take about 5 minutes. | 23:11 |
| gene | what lab? | 23:12 |
| kanzure_ | the one that you have access to | 23:13 |
| kanzure_ | namely Sata's | 23:13 |
| kanzure_ | because he doesn't have download restrictions | 23:13 |
| gene | I ain't gonna be here all week so it don't matter if I use up all the band width | 23:13 |
| kanzure_ | If you really want to use apt-get, which I recommend, then you'd need to get linux first, yes. | 23:13 |
| gene | wait a minute kanzure, your using arctan2 to plot polar equations? | 23:14 |
| gene | may I ask why? | 23:14 |
| kanzure_ | that's cartesian. | 23:14 |
| gene | it makes no sense | 23:14 |
| gene | oh | 23:14 |
| gene | you want to convert to cartesian? | 23:14 |
| gene | polar to cart is easy | 23:15 |
| kanzure_ | well, ultimately GPUs use cartesian coordinates, so whatever I end up using should be in cartesian, but I can convert to and from polar to cartesian with the cosines and sines. | 23:15 |
| kanzure_ | I don't want to convert that equation that I pasted, | 23:15 |
| kanzure_ | you mentioned knowing of something better | 23:15 |
| kanzure_ | which more adequately represents what we're doing | 23:15 |
| kanzure_ | uh, for spirals I mean. | 23:16 |
| gene | yeah man | 23:16 |
| gene | sines and cosine are what you use | 23:16 |
| kanzure_ | What do you have in mind? | 23:17 |
| kanzure | what's with the VTK documentation being 60 MB? | 23:38 |
