| * katsmeow hmms for a bit | 00:01 | |
| katsmeow | if it's that easy, why do people buy $$$ collets? | 00:01 |
|---|---|---|
| fenn | not everyone uses collets | 00:09 |
| fenn | end mills have a tendency to pull out of the collet at high cutting load | 00:10 |
| fenn | the set screw + flat is often called a "weldon" shank | 00:10 |
| fenn | (it's not welded on, believe it or not) | 00:10 |
| fenn | besides, the set screw kicks the bit off center a little, so a collet is better for fine cuts (otherwise you'd be cutting on only one flute) | 00:11 |
| katsmeow | i was thinking a flat stock and a tapered collar and a spring,, sorta thing | 00:11 |
| fenn | like a dremel? not really seeing what you're describing | 00:11 |
| katsmeow | drill the hole like for setscrew, but no threads | 00:12 |
| katsmeow | insert a rod | 00:12 |
| katsmeow | slide a internally tapered collar over it | 00:13 |
| fenn | sounds like a hard way to make a set screw | 00:13 |
| katsmeow | the taper presses the rod into the ding in the bit shaft | 00:13 |
| katsmeow | it's quicker to release and doesn't mar the bit, and won't unscrew | 00:13 |
| fenn | i use a little chunk of brass or aluminum to go the last few thread lengths (you don't want to tap all the way through see) | 00:14 |
| fenn | er, actually it doesn't matter on something as large as 1/2" | 00:14 |
| katsmeow | vibration won't back out the setscrew? | 00:15 |
| fenn | also, that's what the flat on the bit shank is for (so it doesn't mar the shank) | 00:15 |
| * katsmeow nods | 00:15 | |
| fenn | it does work its way loose without thread lock | 00:15 |
| fenn | you really should have two set screws on a shaft at 90 or 120 degrees | 00:16 |
| katsmeow | collar on the outside of the shaft | 00:16 |
| fenn | but all the endmills with flats only have one flat *shrug* | 00:16 |
| fenn | pro-feshnul grade tooling: http://www.iscar.com/Ecat/products.asp/app/111/mapp/IT/GFSTYP/M/lang/EN | 00:17 |
| katsmeow | i'd never get a taper to match those | 00:19 |
| fenn | probably not | 00:19 |
| katsmeow | ergo, i cannot use them | 00:21 |
| katsmeow | http://www.iscar.com/Ecat/products.asp/app/94/mapp/IT/GFSTYP/M/lang/EN ? | 00:23 |
| katsmeow | i think i'll do it like you did | 00:24 |
| katsmeow | i was thinking of something like http://www.iscar.com/Ecat/familyHDR.asp/fnum/2078/app/106/mapp/IT/GFSTYP/M/type/1/lang/EN | 00:26 |
| katsmeow | but with a tapered outside, so a collar driven down from above would compress the fingers onto the bit | 00:26 |
| genehackerclone | oh dear ybit | 00:40 |
| genehackerclone | that is $30 | 00:41 |
| genehackerclone | toobad it's not automatic | 00:41 |
| katsmeow | if you had a core small enough to spec 2 source register , one target register, and some logic or short math op in the one 32bit instruction, and it executed in 1ns, izzat good or no? what if you could simultaneously feed it another 32bit instruction into the other side, to do something to the registers not spec'd in the other instruction? | 00:54 |
| katsmeow | or for that matter, OR reg1 and reg2 and store in reg3, and same time AND reg1 and reg2 and store in reg4 | 01:39 |

| drazak | kanzure, fenn | 07:34 |
| kanzure | drazak: yeah it's not really diy because jason bobe has some contacts with companies and he's having people snailmail them cotton swab samples | 07:58 |
| drazak | lololol | 08:00 |
| drazak | that's pathetic | 08:00 |
| kanzure | I don't know if I care enough to reply to this bullshit: | 08:08 |
| kanzure | http://diybio.org/forums/comments.php?DiscussionID=7&page=1#Item_0 | 08:08 |
| drazak | that's kinda bs-y | 08:14 |
| kanzure | hm, I want a history book of the F/OSS software movement | 08:20 |
| kanzure | I want to see a chapter on X, a chapter on gentoo, a chapter on debian, etc. | 08:20 |
| kanzure | and a chapter on KDE | 08:20 |
| drazak | kanzure: you should make a big reply to my post | 08:26 |
| drazak | and be like | 08:26 |
| drazak | zem bitches yo they not be doin it home schooled, you gots to do it yourself to bes diy yo | 08:27 |
| kanzure | the reason why it's on diybio.org is because jason bobe is in bed with mac | 08:30 |
| kanzure | fenn: http://adl.serveftp.org/lab/opencascade/gp-ax2-test.txt not sure if it matters though | 08:33 |
| drazak | kanzure: probably literally | 08:36 |
| kanzure | I don't think they realize that they are holding diybio back by all their bullshit | 08:40 |
| drazak | I get the impression that they don't give a shit | 08:42 |
| drazak | it's a status symbol for them | 08:42 |
| kanzure | status symbol? | 08:47 |
| drazak | yeah | 08:49 |
| drazak | 'oh yeah I'm the head of diybio!' | 08:49 |
| drazak | they don't give a shit about getting stuff done, they just like saying that they're the ones forwarding the movement | 08:49 |

| fenn_adl | hmm. http://www.impactlab.com/2008/05/08/world’s-tallest-lego-tower-built-in-england/17596/ | 10:39 |
| fenn_adl | iron python wouldn't let me load Representation.dll | 10:39 |
| fenn_adl | so, i have lost interest in it | 10:40 |
| fenn_adl | oh. the bastard wanted c:/ instead of c:\ | 10:44 |
| fenn_adl | since the scrollback is only two pages long they could at least include a pager | 10:45 |
| fenn_adl | does Representation%28GraphSynth%29.dll do anything extra? | 10:50 |
| fenn_adl | it seems once i import GraphSynth.FundamentalClassesAndInterfaces.dll i get the complete GraphSynth API | 10:50 |
| fenn_adl | lego automated book scanner http://www.geocities.jp/takascience/lego/fabs_en.html | 11:01 |
| fenn_adl | doesn't really cradle the book at an angle though so you get warped scans | 11:04 |
| kanzure | oh, if you get the complete API with just FundamentalClassesAndInterfaces then by all means | 11:06 |
| kanzure | I looked ati t with dir() and didn't see Representation or designGraph, but I cofuld have been mistaken | 11:06 |
| kanzure | any idea about getting something better than the ironpython interpreter? the interactive interprreter really, really sucks | 11:07 |
| fenn_adl | i bet you could use ipython somehow | 11:07 |
| * kanzure wonders if there is something about lags that make him make more typos, or simply the fact that he doesn't see what he's typing. hm. | 11:07 | |
| fenn_adl | why are you lagged? | 11:07 |
| kanzure | home connection is still having difficulties apparently | 11:07 |
| kanzure | *di | 11:07 |
| kanzure | fficulties | 11:07 |
| fenn_adl | so, run your irssi at home? | 11:08 |
| fenn_adl | btw clr.Add.. %28GraphSynth%29.. doesn't work | 11:12 |
| fenn_adl | i had to do (GraphSynth) | 11:12 |
| fenn_adl | and anyway it still doesn't show designGraph | 11:13 |
| fenn_adl | how come nobody uses the phrase "assembly graph" | 11:13 |
| kanzure | AddFile isn't sufficient | 11:14 |
| fenn_adl | i only see one example (NASA/ISS) and it's not even a graph | 11:14 |
| kanzure | check out the tutorial distributed with IronPython | 11:14 |
| kanzure | http://groups.google.com/group/opencascade_group ugh | 11:14 |
| fenn_adl | yeah i have it open | 11:14 |
| kanzure | clr.AddReferenceToFileAndPath | 11:14 |
| kanzure | that's what I used | 11:14 |
| fenn_adl | then import GraphSynth as gs | 11:14 |
| kanzure | then impoprt GraphSynth.Representation | 11:15 |
| fenn_adl | oh. duh | 11:16 |
| * kanzure bonks fenn over the head with a frying pan | 11:16 | |
| fenn_adl | well that was easier than i expected | 11:17 |
| kanzure | if you want to get jiggy with it and monodevelop, sudo apt-get install monodevelop libnunit2.4-cil nunit nunit-console nunit-gui monodevelop-nunit | 11:17 |
| fenn_adl | what's nunit? | 11:17 |
| kanzure | c# unit test framework that is also integrated into the monodevelop gui | 11:18 |
| fenn_adl | um. how do i get out of ipy | 11:19 |
| kanzure | CTRL+Z | 11:19 |
| fenn_adl | >>> exit() | 11:20 |
| fenn_adl | Traceback (most recent call last): | 11:20 |
| fenn_adl | TypeError: str object is not callable | 11:20 |
| kanzure | ctrl+z | 11:20 |
| fenn_adl | why is 'exit' a string object? | 11:20 |
| kanzure | print exit | 11:20 |
| fenn_adl | omfg | 11:20 |
| fenn_adl | someone needs to be shot | 11:20 |
| kanzure | yeah .. :( | 11:20 |
| kanzure | btw try this: press "home" or "end" then type exit | 11:20 |
| fenn_adl | exit() works on ipy.exe | 11:20 |
| kanzure | when I type home/end before anything else, I get this: | 11:21 |
| kanzure | >>> exit | 11:21 |
| kanzure | Traceback (most recent call last): | 11:21 |
| kanzure | SyntaxError: unexpected token bad character '' (<stdin>, line 1) | 11:21 |
| kanzure | usually I navigate to the beginning or end of a line with those keys | 11:21 |
| kanzure | and usually I use up/down arrows to navigate up/down in the history, but that also causes the same problem | 11:22 |
| fenn_adl | right | 11:22 |
| fenn_adl | i use C-a and C-e | 11:22 |
| fenn_adl | (neither of which work in ipy either) | 11:22 |
| kanzure | isn't this basic interpreter functionality? | 11:22 |
| kanzure | basic interactive interpreter functionality, I mean | 11:23 |
| kanzure | so how do I actually stop ipy? ctrl+z just moves it to the background | 11:24 |
| kanzure | besides killing it | 11:25 |
| fenn_adl | hm even up-arrow works on windows at least | 11:25 |
| kanzure | is there another way to exit python sessions that I am not aware of? exit, quit, ctrl+z, .. ? | 11:26 |
| kanzure | dir() doesn't show "quit" or "exit" | 11:26 |
| fenn_adl | ctrl+d | 11:26 |
| fenn_adl | dir(__builtins__) but it's just a string | 11:26 |
| kanzure | nope, just inserts the ctrl+d unicode character into the prompt | 11:26 |
| kanzure | >>> | 11:27 |
| kanzure | Traceback (most recent call last): | 11:27 |
| kanzure | SyntaxError: unexpected token bad character '(<stdin>, line 1) | 11:27 |
| kanzure | gee I'm starting to feel stupid | 11:27 |
| fenn_adl | i dont really get why this isnt just a python module | 11:27 |
| fenn_adl | ironpython.GetSomeStupidFuckingDll("c:/foo.dll") | 11:27 |
| fenn_adl | i mean it doesn't even import python modules | 11:28 |
| fenn_adl | ImportError: No module named yaml | 11:28 |
| kanzure | well what's sys.path? | 11:29 |
| fenn_adl | /usr/lib/python2.4 | 11:29 |
| kanzure | is that where the yaml module is? | 11:29 |
| fenn_adl | no | 11:29 |
| kanzure | makes me wonder | 11:29 |
| kanzure | hah I have to killall -9 mono to kill ipy? | 11:30 |
| fenn_adl | it still doesn't work even if i add the right paths | 11:30 |
| fenn_adl | ctrl-z then kill %1 in a shell | 11:31 |
| fenn_adl | dunno how mono does it | 11:31 |
| fenn_adl | either way it's stupid | 11:31 |
| fenn_adl | well at least i can copy+paste on linux | 11:33 |
| kanzure | I'd tell you how to do it on windows in their cmd32, but it would only make you die a little bit more inside | 11:37 |
| kanzure | it involves right clicking on the window title bar | 11:38 |
| fenn_adl | so. do i have to recompile *.dll to be able to import it on linux? | 11:38 |
| kanzure | not sure. | 11:38 |
| fenn_adl | did you? | 11:38 |
| kanzure | I've recompiled them | 11:38 |
| kanzure | yes | 11:38 |
| fenn_adl | want to put those files somewhere? | 11:39 |
| kanzure | didn't try the other way though | 11:39 |
| kanzure | yeah one sec | 11:39 |
| kanzure | what do you want? | 11:39 |
| fenn_adl | fundamental and representation | 11:39 |
| fenn_adl | just the dll should be enough right? | 11:39 |
| kanzure | yes | 11:39 |
| kanzure | dll =~ .lib | 11:39 |
| fenn_adl | did you ever add any if(using_wpf) statements? | 11:40 |
| kanzure | was a preprocessor directive | 11:40 |
| kanzure | yes | 11:40 |
| kanzure | ok added two DLLs to http://adl.serveftp.org/lab/ | 11:41 |
| kanzure | GraphSynth.FundamentalClassesAndInterfaces.dll | 11:41 |
| kanzure | Representation%28GraphSynth%29.dll | 11:41 |
| fenn_adl | i forget how to use mono every time... | 11:41 |
| kanzure | well I just did it in monodevelop to be honest | 11:41 |

| kanzure | should I do that? I feel unclean including an image in my email | 12:10 |
| fenn_adl | honestly i hate attachments | 12:10 |
| fenn_adl | but if he's asking you might as well | 12:11 |
| kanzure | "Can you please insert the screenshot in your email? I don't manage to open/display the png file.." | 12:11 |
| kanzure | but it seems fine to me: http://adl.serveftp.org/lab/opencascade/opencascade_coordinate_axis_arrows.png | 12:11 |
| fenn_adl | it's pretty lame that the default error for an un-configured svn over http is "repository permanently moved" | 12:12 |
| fenn_adl | try encoding as .jpg :) | 12:13 |
| fenn_adl | "i see the screenshot but my brain refuses to interpret it correctly!" | 12:14 |
| kanzure | how could you *not* open png? | 12:14 |
| fenn_adl | maybe he's using IE4 | 12:14 |
| kanzure | that's about the only possibility | 12:15 |
| fenn_adl | erm. was this just a couple minutes ago? | 12:15 |
| kanzure | yes | 12:15 |

| kanzure | how does that happen? | 12:19 |
| fenn_adl | DAV | 12:20 |
| kanzure | can we disable that? | 12:20 |
| fenn_adl | WebDAV ('Web-based Distributed Authoring and Versioning') functionality for Apache. This extension to the HTTP protocol allows creating, moving, copying, and deleting resources and collections on a remote web server. | 12:20 |
| fenn_adl | wah | 12:22 |
| fenn_adl | this should be on sourceforge or something anyway | 12:23 |
| kanzure | fenn did you run paths.py yet? | 12:33 |
| fenn_adl | no, why? | 12:33 |
| kanzure | did what you suggested | 12:34 |
| kanzure | http://adl.serveftp.org/lab/opencascade/opencascade-coordinate-ax3.png | 12:38 |
| fenn_adl | cool it works, and doesn't store passwd in plaintext | 12:40 |
| kanzure | svn stored passwd in plain text? | 12:43 |
| kanzure | so I'm a little concerned that there is nothing pointing in the positive y direction when I permutate across the possibilities for directions and vx vectors. | 12:44 |
| fenn_adl | well i dunno what /var/www/adl/conf/passwd is, you tell me | 12:45 |

| ybit | i hadn't seen that particular message | 13:18 |
| ybit | i've seen every other post on toolbook | 13:18 |
| fenn_adl | oh i see, ironpython is actually running in .NET | 13:18 |
| fenn_adl | however, there's also http://pythonnet.sourceforge.net/ | 13:19 |
| ybit | why are you looking at alternative python shells? | 13:19 |
| kanzure | BECAUSE IRON PYTHON SUCKS | 13:19 |

| fenn_adl | what's the fucking point of that | 13:22 |
| kanzure | does it run under wine or mono? | 13:23 |
| fenn_adl | "install the Windows version of Mono to run .NET executables" | 13:24 |
| fenn_adl | that's what the .exe i just compiled says | 13:24 |
| ybit | kanzure: so how did you finally get out of ipy? | 13:24 |

| ybit | speaking of squatting, i've wondered why heath.im doesn't forward properly to a dyndns address. | 13:29 |
| kanzure | forwarding sucks | 13:29 |
| ybit | i hate that address, but it might as well be going somewhere while it exists | 13:29 |
| fenn_adl | because it's pointing at 217.70.184.38 | 13:29 |
| fenn_adl | you need CNAME heath.dyndns.org or whatever | 13:29 |
| fenn_adl | ybit: do 'dig heath.im' | 13:30 |
| fenn_adl | then do 'dig fennetic.net' | 13:30 |

| fenn_adl | doesn't it say how many hours on the paycheck? | 13:32 |
| kanzure | yes but I'm only on the bank site | 13:33 |
| fenn_adl | do you actually get a paycheck stub html page somewhere? | 13:33 |
| kanzure | yes | 13:34 |

| fenn_adl | looks sort of like a bottle rocket | 14:04 |
| kanzure | did that actually do anything? | 14:06 |
| fenn_adl | now you can see 4 arrow heads in a cluster | 14:07 |
| fenn_adl | cone probably isnt the best shape for this | 14:07 |
| fenn_adl | a 'flag" would be better but i dunno how to do that easily | 14:08 |
| * fenn_adl tries out BRepBuilderAPI_MakePolygon | 14:09 | |
| CIA-32 | skdb: fenn * r 3df3929 /paths.py: change cone to flag shape | 14:28 |
| fenn_adl | should look like this http://adl.serveftp.org/lab/fenn/pngs/occ_fubar.png | 14:30 |
| kanzure | what are the flags indicating? | 14:31 |
| fenn_adl | rotation around the axis of the flag | 14:36 |
| kanzure | what's teh game plan? | 14:39 |
| kanzure | I don't really know what to do | 14:39 |
| kanzure | first of all, shouldn't the red arrow be pointing outwards? perpendicular to the blue line | 14:43 |
| fenn_adl | make a function to convert (point, x_vec, y_vec) to (gp_Ax1, rotation) | 14:43 |
| kanzure | where rotation is a number, not any special object? | 14:44 |
| fenn_adl | yeah | 14:44 |
| fenn_adl | another way to think about it is (point, normal vector, rotation) | 14:45 |
| kanzure | what would thisw be sed for? | 14:45 |
| kanzure | *used for | 14:45 |
| fenn_adl | that might be more useful actually, not having to go through OCC | 14:45 |
| kanzure | *this | 14:45 |
| kanzure | okay | 14:45 |
| fenn_adl | well point_shape works well enough | 14:45 |
| fenn_adl | so i'll just use that instead of SetTransformation | 14:45 |
| fenn_adl | i dont know how to get the rotation around Z given X and Y vectors | 14:46 |
| kanzure | you'll use point__shape() instead of SetRotation? | 14:46 |
| fenn_adl | uh, i think point_shape uses SetRotation | 14:46 |
| kanzure | sorry, SetTransformation | 14:46 |
| kanzure | gah, I was wondering what "that" was for 14:45 | 14:46 |
| fenn_adl | yes, use point_shape instead of SetTransformation | 14:47 |
| fenn_adl | point_shape can return the transform instead of causing side effect | 14:47 |
| kanzure | then you don't want the converter function? | 14:48 |
| fenn_adl | point_shape doesn't give me rotation around the normal :( | 14:48 |
| fenn_adl | should probably split out the mathy parts of point_shape into a different function | 14:49 |
| fenn_adl | something that just always returns a trsf | 14:49 |
| fenn_adl | point, x_vec, y_vec in, trsf out | 14:50 |
| kanzure | is it possible to go from point, x_vec and y_vec to get a rotation around a normal vector? the normal vector is the dot product, but the rotation is not necessarily known .. is it? | 14:54 |
| kanzure | er, cross product | 14:54 |

| kanzure | guess I'm not really sure :) there's this slight chance I might choose to fly up to CA for a juicy 'job' | 15:54 |
| kanzure | hm I haven't checked, they don't tell us professors usually | 15:54 |
| kanzure | they just give us times | 15:54 |

| fenn_adl | it's true, i can provide evidence | 15:57 |
| kanzure | wait wait, I'm being sarcastic, fenn | 15:57 |
| fenn_adl | oh, ok. nevermind then | 15:57 |
| kanzure | don't you have a bus to catch? | 15:57 |

| kanzure | did you install it? | 16:00 |
| kanzure | it's not named Outcome | 16:00 |

| fenn_adl | gah | 16:01 |

| drazak | so uh | 17:21 |
| drazak | I need to figure out how to molecularly prove that some shit interact | 17:21 |
| drazak | so | 17:21 |
| drazak | well that was a bad description | 17:21 |
| drazak | so there's these proteins called cadherins, they anchor cells to one another, gap junctions like to form near them, inside the cells part of the cadherin interacts with beta-catenin and forms a sort of cellular signalling network, I want to see if beta-catenin loses amino acids when it's interacting with cadherin, what's the best way to do this? | 17:23 |
| fenn | auto-apt checks the file access of programs running within its environments, and if a program tries to access a file known to belong in an uninstalled package, auto-apt will install that package using apt-get. | 17:26 |
| fenn | i wonder how it knows which one to get | 17:26 |
| fenn | if there are multiple choices, that is | 17:26 |
| kanzure | drazak: IIRC, these types of studies usually involve crystallography at one point or another unless you know what you're doing | 17:26 |
| fenn | no, binding affinity doesn't use crystallography | 17:27 |
| kanzure | he said loses amino acids | 17:27 |
| kanzure | that's structural | 17:27 |
| fenn | you could find the amino acid sequence | 17:27 |
| fenn | i dont really know how that works though | 17:27 |
| drazak | kanzure: well what I think happens is that the protein loses some off either it's c or n terminus | 17:28 |
| drazak | kanzure: because it's only a small difference in size, 2-3kDa | 17:28 |
| drazak | kanzure: you can see it on a western blot | 17:28 |
| kanzure | can you mass the subunits of the beta-catenin? | 17:29 |
| fenn | it could be a kinase phosphorylation maybe | 17:29 |
| drazak | fenn: usually phosphorylation doesn't cause a noticable size change with sds page | 17:29 |
| drazak | kanzure: I want to do some sort of protease footprinting | 17:30 |
| drazak | kanzure: my hypothesis is that when beta-catenin and n-cadherin interact beta-catenin is the same as the rna would lead you to believe, and then something happens to the cadherin, we know they have some sort of signaling or phosphorylization that causes something to happen, and then it cuts off part of the beta catenin and it acts like a transcription factor (the main part of the beta catenin) | 17:31 |
| drazak | hmm I could do a gel-shift with recombinant beta-catenin, in it's natural state, from n-cadherin- cells | 17:33 |

| kanzure | thank you basic geometry man | 18:10 |
| kanzure | QuantumG: could you solve our matrix math difficulties? | 18:11 |
| fenn | it's not actually our matrix math that's causing the difficulty | 18:11 |
| QuantumG | maybe, what's the problem? | 18:11 |
| fenn | i want to transform from one coordinate system to another (no scaling) | 18:11 |
| QuantumG | rebasing | 18:11 |
| fenn | i have a point and two vectors (the x and y axis) | 18:12 |
| fenn | so in opencascade you make a transformation by doing gp_Trsf() and then calling methods like SetRotation or SetTranslation | 18:12 |
| fenn | there's also one called SetTransformation which accepts a coordinate system | 18:12 |
| fenn | but, as i eventually figured out, it doesn't work right | 18:13 |
| fenn | but the SetRotation and SetTranslation stuff does | 18:13 |
| fenn | so i'm trying to construct a series of rotations to create the same transformation as i would have gotten by setting it directly | 18:14 |
| fenn | is this making sense? | 18:14 |
| QuantumG | ahh | 18:15 |
| fenn | i know how to derive azimuth and elevation angles, given a vector, but how do i find the rotation around the vector (around the vector's axis) | 18:15 |
| QuantumG | http://www.sosmath.com/matrix/eigen1/eigen1.html any of that help? | 18:16 |

| QuantumG | is there some reason you're not using the dot product? | 18:21 |
| fenn | kanzure: i think it's the inverse of f(x)=p*cos(x)-q*sin(x) and g(x)=p*sin(x)+q*cos(x) | 18:21 |
| fenn | dot product projects one vector on another right? | 18:21 |
| fenn | the magnitude | 18:21 |
| kanzure | there's actually a way to calculate vector projections if that's what you're asking | 18:22 |

| kanzure | not sure "angle between two vectors" is right because that's what I did and fenn says it's wrong | 18:24 |
| fenn | it's the same equation you had | 18:24 |
| kanzure | well technically I forgot to divide by the product of their absolute magnitudes | 18:24 |
| QuantumG | so.. knowing what your problem is would be a good start. | 18:24 |
| fenn | dammit i know what the problem is | 18:25 |
| QuantumG | we dont obviously | 18:25 |
| fenn | i have two vectors, i rotate azimuth and elevation to get the first vector | 18:25 |

| kanzure | baud_fox: think of a factory as /dev more than anything- and if you don't have those tools wired up, then you should be able to read instructions on how to put things together. | 18:37 |
| kanzure | baud_fox: that might not be the answer you were looking for | 18:37 |

| baud_fox | kanzure: still don't quite understand. Are we talking about modular hardware? | 18:40 |
| kanzure | what is modular hardware? | 18:40 |
| fenn | the idea is if you need to dig a hole you apt-get install backhoe | 18:41 |
| fenn | and if there's no precompiled backhoe available, you assemble it from parts | 18:41 |
| baud_fox | a PC, for example - different hardware modules which can be added/configured depending on the application | 18:41 |
| fenn | and if there's no parts available, you compile the parts from metals | 18:41 |

| fenn | oh come on, if it's anything like any other #subject channel it's 90% bullshitting and 10% esoterica | 19:01 |
| kanzure | well it's different. don't know how to explain it. | 19:01 |
| ybit | haha, love how the first comment is on how ugly it is | 19:04 |
| kanzure | 19:04 < purplepenguins> lol | 19:04 |
| kanzure | 19:04 < purplepenguins> that's the best illustration ever | 19:04 |
| fenn | sigh | 19:05 |
| kanzure | #math says it is incomprehensible | 19:05 |
| kanzure | (aside from the ugliness) | 19:05 |

| ybit | kanzure: i forget his name, and yeah i was about to baud_fox a few questions | 19:08 |

| ybit | oh, i think it's something like TMZ[BLAH] | 19:08 |
| ybit | ALLCAPS | 19:08 |
| genehacker | modular hardware is hardware that comes in modules | 19:09 |
| ybit | anywho, i'm going to complete my todo list and go night night early | 19:09 |
| kanzure | ybit: see? you spend all of your time todoing | 19:09 |
| kanzure | rather than doing | 19:09 |
| ybit | this is me completing today's todo | 19:09 |
| genehacker | for example robot arm can attach to a point that could also hold a sensor module | 19:10 |
| genehacker | modular hardware would be cool | 19:10 |
| genehacker | if everything was modular and everything could connect | 19:10 |
| kanzure | you mean, "interchangeable parts"? | 19:10 |
| kanzure | like the fraud that was known as "the industrial revolution"? | 19:10 |
| genehacker | yeah | 19:11 |
| genehacker | screws are almost interchangeable | 19:11 |
| kanzure | http://adl.serveftp.org/lab/opencascade/gp_Trsf.cxx | 19:24 |
| fenn | screws are interchangeable | 19:25 |
| fenn | so are gears | 19:25 |
| fenn | nothing else mechanical seems to have reached a similar level of standardization | 19:26 |
| kanzure | fenn: loc.Reverse() is just set x=-x, y=-y, z=-z for gp_XYZ | 19:27 |
| kanzure | that's because to the untrained eye it's just "random chunks and hunks of metal" | 19:27 |
| kanzure | "a rod? why would you standardize a rod" | 19:27 |
| fenn | are you referring to something in particular? | 19:27 |
| kanzure | no | 19:27 |
| kanzure | http://adl.serveftp.org/lab/opencascade/gp_Trsf.cdl | 19:29 |
| kanzure | doesn't look too much different from the HTML reference documentation however | 19:29 |
| kanzure | so why does SetTransformation(from, to) use | 19:32 |
| kanzure | matrix.SetCol (1, ToA2.XDirection().XYZ()); | 19:32 |
| kanzure | but in SetTransformation(to) there's: | 19:32 |
| kanzure | matrix.SetCols (A3.XDirection().XYZ(), | 19:32 |
| kanzure | A3.YDirection().XYZ(), | 19:32 |
| kanzure | A3. Direction().XYZ()); | 19:32 |
| kanzure | I'm guessing it's practically the same thing but maybe it's possible the implementation is wrong? | 19:32 |

| baud_fox | Greetings | 19:34 |
| kanzure | greetings | 19:34 |
| baud_fox | Apologies for the abrupt departure | 19:35 |
| baud_fox | I'm still not clear what this hardware project is btw. I'm curious, but confused. | 19:37 |
| baud_fox | It almost sounds like we're talking about a universal assembler. | 19:38 |
| kanzure | well we're certainly interested in universal von Neumann self-replicating machines. | 19:42 |
| ybit | but that's not what it is | 19:42 |
| kanzure | ideally, I want to be able to sit at my computer and demand my machines make me my tools to make even more stuff | 19:43 |
| kanzure | but in the mean time I'm happy carrying out instructions to build things that I would otherwise not know how to build | 19:43 |
| kanzure | (this is called skdb, btw) | 19:43 |
| ybit | build me a screw! | 19:43 |
| kanzure | never! | 19:43 |
| baud_fox | Ahh, ok | 19:43 |
| kanzure | oh wait | 19:43 |
| * kanzure gives ybit a screw | 19:44 | |
| baud_fox | So how would you achieve this? Through something like rapid prototyping? | 19:44 |
| kanzure | rapid prototyping is a subset of the manufacturing techniques involved | 19:44 |
| kanzure | one moment .. | 19:44 |
| ybit | any machine needed to build whatever it is that you are building | 19:44 |
| kanzure | so there are some "techniques" like rapid prototyping, or milling, etc. that are included | 19:45 |
| kanzure | see here: | 19:45 |
| kanzure | http://adl.serveftp.org/skdb/processes.yaml | 19:45 |
| kanzure | here are some "packages" that you can download and have your computer build: | 19:45 |
| kanzure | http://adl.serveftp.org/skdb/packages/ | 19:45 |
| kanzure | the "screw" package depends on a thread rolling technique, for instance, which you might know or have a machine that implements (a thread rolling technique) | 19:45 |
| baud_fox | fascinating | 19:45 |
| * ybit wonders if some hackerspaces implementing this system will have machines continually processing raw materials and shipping them off | 19:47 | |
| kanzure | ybit: well that's the idea isn't it? smt machines already do that | 19:48 |
| kanzure | but they don't operate under this sort of framework | 19:48 |
| kanzure | mostly because I don't have an smt machine to play with :p | 19:48 |
| ybit | because naturally some spaces will be closer and have more of certain raw materials then others | 19:48 |
| kanzure | smari was working on an xmlrpc system for order requests across multiple fablabs | 19:48 |
| drazak | kanzure: so what sort of data is the lab supposed to send back | 19:59 |
| drazak | kanzure: that takes so much analysis on the diy communities part | 19:59 |
| kanzure | fuck if I know | 20:03 |
| drazak | I mean | 20:03 |
| drazak | presumably they just tell you what species it is | 20:03 |
| kanzure | "The Foresight Nanotech Institute (formerly Foresight Institute) is a Palo Alto, California-based nonprofit organization for increasing awareness about the uses and consequences of molecular nanotechnology. They sponsor conferences on the subject, publish reports, and produce a newsletter." | 20:19 |
| kanzure | Foresight Institute was founded to guide emerging technologies to improve the human condition but focused its efforts upon nanotechnology, the ability to engineer materials and products with atomic precision, and upon systems to enhance communication for policy decisions. "[1] In 2005 the Foresight Institute changed its name to "Foresight Nanotech Institute" and narrowed its mission to nanotechnology. | 20:20 |

| fenn | actual cad files seem to be hard to come across | 22:43 |
| fenn | there are probably a zillion artistic 3d models out there though | 22:43 |
| fenn | duh. how about this? http://www.3dcadbrowser.com/preview.aspx?ModelCode=3229 | 22:44 |
| genehacker | that's because actual cad files are usually made by companies | 22:49 |

| ybit | fenn: "Please register and/or login before unlocking and downloading 3D models." | 23:12 |
| ybit | and you have to pay to download the cad files | 23:13 |
