13:38 < CryptoQuick> kanzure: hey bud, you there? :)
13:38 < CryptoQuick> I need yo helpz
13:39 < CryptoQuick> I want to make a web-based CAD, with parametric geometry and basic CSG ops using WebGL. I'm cool if that's done in another language, I can always work through some python and stuff. I'm just concerned about turning parametric solids into mesh geometry. Is there anything out there already that can help?
14:08  * mayko is back (gone 02:13:54)
14:15 < kanzure> okay
14:15 < kanzure> CryptoQuick: parametric->mesh is easy
14:16 < kanzure> the parametric part is the hard part.. would you be interested in helping me implement it?
14:16 < CryptoQuick> kanzure: yeah?

14:16 < CryptoQuick> sure, actually
14:16 < CryptoQuick> if it's in JS, of course
14:16 -!- Technicus [~nomadicus@66-190-14-100.dhcp.stpt.wi.charter.com] has quit [Ping timeout: 258 seconds]
14:16 < kanzure> would you be ok i the webgl/javascript part interfaces with a server where the CAD kernel sits?
14:16 < kanzure> i see..
14:16 < kanzure> well that makes it a little harder
14:16 < CryptoQuick> hmm
14:16 < CryptoQuick> I mean, yeah, you could use PyOCC
14:17 < kanzure> hmm no
14:17 < kanzure> i was rewriting a CAD kernel in python a while back
14:17 < kanzure> because opencascade is so awful
14:17 < kanzure> http://diyhpl.us/cgit/lolcad/plain/esolid/esolid.py
14:17 < CryptoQuick> buh!
14:17 < kanzure> then i started a wrapper that would wrap both esolid and pythonocc
14:17 < CryptoQuick> kanzure: it's so ... big! I'm not sure I'll be able to handle it all~
14:17 < kanzure> i'd be ok with writing a cad kernel in vanilla python or vanilla javascript though
14:17 < kanzure> yeah...
14:17 < kanzure> just let the tip in
14:18 < CryptoQuick> just the tip? ok, well, as long as it's only a little bit
14:18 < kanzure> anyway, imho this is the remaining task to be done
14:18 < kanzure> i have been working off of a set of papers
14:19 < CryptoQuick> I'm currently making a boilerplate Three.js Canvas renderer script, very simple stuffs
14:19 < CryptoQuick> and that's always a good thing
14:19 < kanzure> meh that's not a chokepoint dude
14:19 < CryptoQuick> ofc not
14:19 < CryptoQuick> just having a fun
14:19 < kanzure> http://webgl.pythonocc.org/ is also something but i think it was just a renderer
14:19 < kanzure> let me upload the paper or find it..
14:19 < CryptoQuick> yeah
14:19 < CryptoQuick> they use Three.js
14:19 < CryptoQuick> but I think they're using the WebGL renderer
14:20 < kanzure> this is the software i've been basing some of my wokr on:
14:20 < kanzure> http://gamma.cs.unc.edu/ESOLID/
14:20 < kanzure> at one point they hhooked it up to BRLCAD but deleted their work? they are pretty awful
14:21 < CryptoQuick> hmm
14:21 < kanzure> here's the guy's thesis:
14:21 < kanzure> https://wwwx.cs.unc.edu/~geom/papers/documents/dissertations/keyser00.pdf
14:21 < kanzure> here's the source code:
14:21 < kanzure> http://research.cs.tamu.edu/keyser/geom/esolid/releases/version_0.3/ESOLID-0.3.tar.gz
14:21 < CryptoQuick> well, it's nice to have CSG and stuff, but what I really want is to perform basic CSG ops on arbitrary 2D vector drawings, in respect to other parametric solids, just like SolidWorks
14:22 < kanzure> in lolcad.git you can see my cython wrapper.. (esolid.py is my own implementation)
14:22 < kanzure> yeah this is the implementation for operations like union and difference and intersection
14:23 < CryptoQuick> intersection not so super intuitive-- is that ever used in SolidWorks?
14:23 < kanzure> intersection is like "take the common area between two somewhat overlapping cubes"
14:23 < CryptoQuick> I've worked with stuff like OpenSCAD, and I've done pretty cool things with it, mind you
14:23 < CryptoQuick> and yeah, I know :)
14:23 < kanzure> openscad sucks for a few reasons:
14:23 < kanzure> 1) custom language.. yawn
14:24 < CryptoQuick> it's easy syntax though
14:24 < kanzure> 2) all of their boolean operations are just based on hiding/showing shit in opengl buffers
14:24 < kanzure> well, they have some python wrappers now
14:24 < kanzure> pyopenscad, openscadpy, cadmium, etc.
14:24 < CryptoQuick> mmh
14:24 < CryptoQuick> their program is very hardware heavy
14:24 < kanzure> cloudscad did some javascript wrapper i think.. it involved bouncing shit back to a server
14:24 < CryptoQuick> yeah...
14:25 < kanzure> someone else was making a webgl/javascript library that talked to opencascade (pythonocc?) on a server
14:25 < kanzure> anyway, i'm totally down for writing a javascript library (or any library)
14:25 < CryptoQuick> oh sweet
14:25 < kanzure> once it's in python or javascript and if it's written well enough then it's not that hard to translate it into whatever.. or just stay with it
14:25 < CryptoQuick> yeah, definitely
14:25 < kanzure> with the help of v8 any js library will work fine with python anyway
14:26 < CryptoQuick> be faster than python ;D
14:26 < CryptoQuick> V8 changed everything
14:26 < kanzure> v8 changed my diapers
14:27 < CryptoQuick> yeah, V8 is good

14:29 < kanzure> going from parametric CAD to STL isn't a big deal.. it's just a tessellation algorithm
14:29 < CryptoQuick> oh nice
14:29 < CryptoQuick> that makes sense
14:29 < kanzure> in lolcad i used wx and opengl to display the objects as you updated them in your interpreter..
14:30 < kanzure> i just used the default sgi-provided tessellator in the glunurbs part of their lirbary
14:30 < kanzure> library
14:30 < CryptoQuick> buh
14:30 < CryptoQuick> SGI
14:30 < kanzure> apparently it has some issues on mesa? fenn's netbook displayed circles as ovals.. or something
14:31 < CryptoQuick> best use canvas, it's very ... compatible.

14:32 < CryptoQuick> wanna see some of my work?

14:32 < CryptoQuick> press E key in either to cycle through pre-built models
14:33 < CryptoQuick> color cube broke in the trozki version, but the trozki version has a working Z-rendering algorithm
14:33 < CryptoQuick> well, relatively working ...
14:34 < kanzure> didn't i see this before?
14:34 < CryptoQuick> also, this in 3D
14:34 < CryptoQuick> http://trozki.org/demos/nanoblok/nb09/
14:34 < CryptoQuick> maybe, been a while dude :)
14:34 < kanzure> some company stole this and got a lot of publicity on HN
14:34 < CryptoQuick> also, a game I never finished ...
14:34 < CryptoQuick> http://trozki.org/demos/apsis/
14:34 < CryptoQuick> ?
14:35 < kanzure> hmm what was this called..
14:35 < CryptoQuick> oh yeah, also
14:35 < CryptoQuick> http://www.infocraft.org/three/
14:35 < CryptoQuick> the conversion was all done by hand though, don't get excited :P
14:35 < kanzure> bah
14:35 < CryptoQuick> it was just a thing to demo a part, shut up :P
14:36 < kanzure> about that last one..
14:36 < kanzure> i wrote the visualizer for http://diyhpl.us/~bryan/papers2/Automated%20Synthesis%20and%20Optimization%20of%20Gear%20Train%20Topologies%20-%20Albert%20Swantner%20-%202009.pdf
14:39 < kanzure> hrmm i'm trying to fidn this thing
14:39 < kanzure> it's not thingiview..
14:39 < kanzure> here we go
14:39 < kanzure> CryptoQuick: http://www.3dtin.com/
14:39 < CryptoQuick> yeah
14:39 < CryptoQuick> seen it :)
14:39 < CryptoQuick> very nice stuff
14:40 < kanzure> did they use your code?
14:40 < kanzure> or did you use theirs?
14:40 < CryptoQuick> nah
14:40 < CryptoQuick> neither
14:40 < kanzure> hmmm
14:40 < CryptoQuick> it's more like a Mr. Doob demo
14:40 < CryptoQuick> http://mrdoob.com/projects/voxels/
14:41 < CryptoQuick> they work differently :)
14:41 < CryptoQuick> very differently, actually, considering how my renderer is fixed isometric, and uses a lot of shortcuts because of that.
14:41 < CryptoQuick> it's pretty unique, I'd like to think...
14:42 < CryptoQuick> well, kanz, I'd be cool with a python kernel, I mean, rewriting everything you have in JavaScript is not a productive activity
14:43 < CryptoQuick> well, not terribly productive, you know
14:43 < CryptoQuick> it's not conducive to finishing~
14:43 < CryptoQuick> I fail at finishing :(
14:43 < kanzure> so i have a few gripes about CAD in general,
14:43 < CryptoQuick> RELEASE
14:43 < CryptoQuick> yeah?
14:43 < kanzure> first is that people say it's too hard for 1 person to do
14:43 < CryptoQuick> :T
14:43 < kanzure> the second is that all of the implementations that i have seen-- nobody understands
14:43 < CryptoQuick> mmh
14:43 < CryptoQuick> they're 'I, Pencils'
14:44 < kanzure> so the problem is likely that nobody has simplified the math or an understanding of how to make this sort of software
14:44 < CryptoQuick> quite
14:44 < kanzure> my "terrible scheme" was to write a very simple python library
14:44 < CryptoQuick> sketchup maybe comes close? but not really
14:44 < kanzure> and that by making the library simple enough, the actual codebase would be only maybe 1000 lines
14:44 < kanzure> esolid's codebase is about 20k lines
14:44 < CryptoQuick> ok :)
14:44 < kanzure> opencascade is at least 100k lines
14:45 < CryptoQuick> onoz
14:45 < kanzure> i dunno if you've ever seen the nurbs code in opencascade but it's not pretty
14:45 < kanzure> it's a mix of english, russian and french
14:45 < CryptoQuick> no nurbz maaaan
14:45 < kanzure> from the early 90s
14:45 < CryptoQuick> buh!
14:45 < CryptoQuick> that was back when nurbz was the it girl, i'm sure
14:46 < kanzure> yesterday i was working on lolcad and was going to package up a wrapper on top of it and just use esolid.so as a drop-in library for now
14:46 < kanzure> and slowly replace it with my slightly-working-python-rewrite
14:46 < kanzure> but that doesn't help towards what yuo want (a complete implementation)
14:46 < kanzure> *you
14:47 < CryptoQuick> well, wait, no
14:47 < kanzure> the problem i had with my complete-python-rewrite is that i didn't know how to test it
14:47 < kanzure> you can't just write thousands of lines of python and hope that the CAD works in the end...
14:48 < CryptoQuick> what I need is a library with the basic functionality of a parametric modeling program would occur, the heavy duty math, tesselation, all that, could be used with-- I'd make model data, it would process that data, and I would get mesh data back.
14:48 < kanzure> yep
14:48 < kanzure> well it would include a modeling API
14:48 < CryptoQuick> maybe, but I want to do the modeling in JavaScript really
14:48 < kanzure> yeah you'd do that
14:49 < CryptoQuick> it should really be interface agnostic
14:49 < kanzure> var sphere = new Sphere(); sphere.union(someotherobject)
14:49 < CryptoQuick> sure sure
14:49 < kanzure> can't be stl input
14:49 < CryptoQuick> nah, all solids
14:49 < CryptoQuick> well, wait--
14:49 < CryptoQuick> what about DXF input?
14:50 < kanzure> i haven't worked with that file format much but there's many versions iirc.. like a 3d dxf format even O_o
14:50 < CryptoQuick> I mean, SolidWorks, which I find to be very intuitive, lets you draw the equivalent of DXF at a certain orientation in respect to another object, then that is applied (union, diff) on that object
14:51 < kanzure> ok so you want to extrude sketches
14:51 < CryptoQuick> quite
14:51 < kanzure> i have extruding working in the python version..
14:51 < CryptoQuick> osweet
14:51 < CryptoQuick> well, let's just use the python kernel for now
14:51 < kanzure> well "working" to the extend that i am able to extrude a line into a nurbs object
14:51 < CryptoQuick> XHR2 is fine
14:51 < CryptoQuick> do we really need nurbs yo
14:52 < CryptoQuick> I guess nurbs is helpful for spheres...
14:52 < CryptoQuick> those are a little hard to do in solidworks, but only because it's hard to position the drawings. theoretically you could just draw an arc and revolve it around an axis.
14:53 < kanzure> what? solidworks isn't using nurbs?
14:53 < CryptoQuick> no idea what it does inside the engine...
14:53 < kanzure> what sort of mathematically defined surface are they using under the hood
14:53 -!- Technicus [~nomadicus@66-190-14-100.dhcp.stpt.wi.charter.com] has joined ##hplusroadmap
14:53 < kanzure> i bet it's nurbs man ;)
14:53 < CryptoQuick> o.
14:53 < kanzure> most users don't have to care about it 100% of the time
14:53 < CryptoQuick> so, parametric modeling and nurbs go hand-in-hand
14:54 < kanzure> since they just use primitives and sketches-turned-into-bezier-curves
14:54 < CryptoQuick> hm
14:54 < CryptoQuick> kay
14:55 < CryptoQuick> so, how to get this started ...
14:55 < CryptoQuick> I think what I'll do is try to get a server working with your kernel ?
14:55 < CryptoQuick> I'm thinking something simple, a microframework like Flask
14:55 < CryptoQuick> I love that one
14:55 < CryptoQuick> very easy!
14:56 < kanzure> i would suggest you read thually
14:56 < kanzure> fdfladjfkladf
14:56 < kanzure> fucking irssi
14:56 < kanzure> i would suggest you read the paper actually
14:56 < kanzure> https://wwwx.cs.unc.edu/~geom/papers/documents/dissertations/keyser00.pdf
14:56 < kanzure> there are also shorter review papers of this same work out there..
14:57 < kanzure> shorter paper: http://gamma.cs.unc.edu/ESOLID/keyser02.pdf
14:57 < kanzure> then look over the source code they published..
14:57 < kanzure> http://research.cs.tamu.edu/keyser/geom/esolid/releases/version_0.3/ESOLID-0.3.tar.gz
14:57 < kanzure> unfortunately, it has no license
14:58 < kanzure> i asked john keyser about the licensing about six months ago but he hasn't replied yet
14:58 < CryptoQuick> can't I just use your stuff plz? you're the expert, yo
14:58 < CryptoQuick> and that's why they make libraries, yus
14:58 < kanzure> well, it's a little bit much for me to chew on my own
14:58 < CryptoQuick> oh, you want me to help finish your stuff?
14:58 < kanzure> and it would be great to have someone else looking over my work and these papers
14:58 < CryptoQuick> hmm...
14:59 < CryptoQuick> well, show me what you have so far. is it that one big file you sent me earlier? I'm looking at your git
14:59 < CryptoQuick> http://diyhpl.us/cgit/lolcad/
14:59 < kanzure> it's in lolcad.git somewhat
14:59 < kanzure> let me check what's uncommitted..
15:00 < kanzure> ok it looks like my cython wrapper is in there in lolcad/esolid/wrapper/
15:00 < kanzure> esolid.py is in lolcad/esolid/esolid.py
15:00 < kanzure> esolid.py is my python rewrite from the ground up
15:00 < kanzure> lolcad/esolid/wrapper/wrapper.pyx is my cython wrapper around libesolid.a
15:00 < CryptoQuick> jesus christ
15:00 < CryptoQuick> 4600 lines
15:00 < kanzure> yeah but i dunno if it's working ;)
15:01 < kanzure> that's the part about "i dunno how to test it"
15:01 < CryptoQuick> you ported this mostly from esolid codebase, right?
15:01 < kanzure> i was coding and coding and coding and i realized, i don't know if individual components will work or not
15:01 < kanzure> yes
15:01 < kanzure> so that's why i started the wrapper/wrapper.pyx code
15:01 < kanzure> i figured i'd wrap the library and then slowly replace it after it was working already
15:02 < kanzure> a lot of this seems like it could be replaced by scipy or numpy or something
15:02 < kanzure> like.. why make a custom rational polynomial class?
15:05 < kanzure> the next steps for the cython-based wrapper are to finish fleshing out the methods (easy), then write some converters to take data from libesolid and draw it on screen through opengl
15:06 < kanzure> then slowly-over-time replacing cython with rewritten versions that do not depend on libesolid
15:06 < kanzure> now.. the alternative is to re-do my custom-rewrite-from-scratch, *after* fully understanding that guy's phd thesis :P
15:06 < kanzure> and writing unit tests along the way.
15:06 < CryptoQuick> well, the imports for esolid.py are -very- lightweight
15:06 < CryptoQuick> this could be run on App Engine, for example
15:07 < kanzure> yep
15:07 < kanzure> just lots of math dude
15:07 < kanzure> MATHS!
15:07 < CryptoQuick> i not so gud at mafh :T
15:08 < kanzure> erm.. what does that mean, in your case?
15:08 < kanzure> like surely you can do algebra right?
15:09 < CryptoQuick> oh, dude, I'm not that bad
15:10 < CryptoQuick> I mean, I can use 3D matrix transformations, I've done them before in my code, but usually looking up a lot of documentation on math and code online.
15:10 < CryptoQuick> I've never attempted quaternions, though
15:10 < CryptoQuick> the thing is, I'm not that formally educated
15:10 < CryptoQuick> I'm a terrible student
15:11 < kanzure> matrix transformations are the most complicated thing going on here as far as i can tell
15:12 < kanzure> there's some neat simplifications and tricks that the thesis has, but they are mostly understandable ("you can eliminate these terms because..")
15:13 < CryptoQuick> well at least they don't use lamdas in this code, those are kinda hard to decipher oftentimes
15:13 < CryptoQuick> it's really not all that pythonic, tbh
15:13 < CryptoQuick> did your test file work?
15:14 < kanzure> honestly it's been a while, i forget
15:14 < kanzure> it's not a complete implementation
15:14 < kanzure> it has no syntax errors
15:14 < CryptoQuick> :)
15:14 < kanzure> it's not pythonic- absolutely true.
15:14 < kanzure> i wanted to make sure i knew what was going on..
15:14 < CryptoQuick> heh :)
15:15 < kanzure> but i'm not opposed to "read the papers -> figure out what has to be done -> write a simple version from scratch"
15:15 < kanzure> s/simple/pythonic/
15:15 < CryptoQuick> heh, you use graphs in here
15:15 < CryptoQuick> I've never really implemented graphs before, only trees really
15:15 < CryptoQuick> I've used stuff like octrees and tree search in my game experience, though
15:16 < kanzure> i worked in a graph theory lab for a while (in a mechanical engineering department)
15:16 < CryptoQuick> heh, nice
15:16 < kanzure> http://graphsynth.com/ is some stuff i worked on
15:16 < CryptoQuick> oh right!
15:16 < CryptoQuick> I remember you postan this once o twiz
15:17 < CryptoQuick> so, let's get this show on the road, man. I'm going to test your library out a bit
15:17 < CryptoQuick> let me know if there's any other administrative things you want to do
15:18 < kanzure> you should try to compile esolid from source so that you can test out the cython wrapper i wrote
15:18 < kanzure> there's a lot of problems in the codebase that i fixed, but i haven't produced a set of patches yet
15:18 < kanzure> i think it's worth me making the patches so please bug me about errors that you get

15:19 < CryptoQuick> I'd prefer to work on your py stuff instead ... ?
15:19 < kanzure> how do i generate a set of patches against an entire directory of a project?
15:19 < kanzure> yeah sure.. the cython stuff is python
15:19 < CryptoQuick> you talking about the stuff in /esolid/esolid.py, or /esolid/wrappar ?
15:20 < kanzure> the wrapper is the cython wrapper
15:20 < kanzure> esolid.py is a self-contained partial untested implementation of esolid
15:20 < CryptoQuick> so the wrapper is necessary to run the python? I can't python esolid.py ?
15:20 < CryptoQuick> o i c
15:20 < kanzure> the wrapper is separate
15:20 < CryptoQuick> well, it's better to work off of that, I would think ...
15:20 < CryptoQuick> I see
15:21 < kanzure> off of what?
15:21 < CryptoQuick> esolid.py
15:23 < CryptoQuick> interesting
15:23 < CryptoQuick> yo shell script runs
15:23 < CryptoQuick> teh sweetz
15:23 < CryptoQuick> I wonder what it all means~
15:23 < kanzure> heh
15:23 < kanzure> dunno you'll have to check
15:23 < kanzure> this is a pretty big project, i often forget about huge chunks
15:23 < kanzure> see pm
15:27 < kanzure> ok thanks. cya

23:19 < CryptoQuick> shit, forgot to put notifications back on :P
23:19 < CryptoQuick> so, bud, I did a bunch more research after we talked
23:19 < CryptoQuick> http://cq.1k.ru/cad_research/
23:19 < CryptoQuick> some of that is yours :)
23:20 < CryptoQuick> also, I've done a bit of coding on my renderer
23:20 < CryptoQuick> but yeah, I need to know where to really start on representing a parametric solid
23:21 < CryptoQuick> I think it'd probably be best to port what we need from ESOLID, see how they tackled some issues, you know... but bring it over in coherent pieces, yeah?
23:21 < kanzure> by representing do you mean representing or rendering
23:21 < kanzure> funkhouser.pdf i wish all my pdfs were named funkhouser
23:22 < CryptoQuick> right! :
23:22 < CryptoQuick> :D
23:22 < CryptoQuick> rendering on hold for now
23:22 < CryptoQuick> I mean, like, having a mathematical description of our parametric solid INSIDE the computer (the FILES are INSIDE the COMPUTER!?!?!?)
23:22 < kanzure> okie dokie
23:23 < kanzure> the esolid representation is a little weird in a few places
23:23 < CryptoQuick> no kidding!? :P
23:23 < kanzure> after writing all that code for esolid i was reading that thesis the other day and the section on the representation of trimming curves kinda blew my mind
23:23 < kanzure> it's a little weird in a few places because it's C++ and lots of things are passed by pointers or stored as a pointer to an index and then given a fucking awful variable name
23:24 < CryptoQuick> haha, I saw that!
23:24 < kanzure> btw, in lolcad there's a STEP generator (in lolcad.py) that will be replaced by https://github.com/mpictor/StepClassLibrary
23:24 < kanzure> i think tpaviot made one out of SCL that generates python classes so i'm willing to give that a shot..
23:25 < kanzure> but my generator was hard-coded and is broken
23:25 < CryptoQuick> mmh
23:25 < kanzure> the typical way to write a STEP generator is to write an EXPRESS schema, run it through your EXPRESS compiler, and get back a bunch of STEP classes and read/write tools that you then integrate into your codebase
23:25 < kanzure> (which is what SCL is about)
23:26 < CryptoQuick> well, I think at this point I would like to learn about how this is really done, then I'd like to write a javascript version of a simple CSG and/or boundary modeler
23:26 < CryptoQuick> "simple"
23:26 < kanzure> okay
23:32 < CryptoQuick> also, kanzure, what do you think of this?
23:32 < CryptoQuick> http://pyjs.org/
23:32 < CryptoQuick> I wouldn't mind using that, really, as it meets the condition that this runs clientside.
23:32 < CryptoQuick> it would also mean we could use proper classes~
23:33 < kanzure> uh python can also run client side
23:33 < CryptoQuick> since when
23:33 < CryptoQuick> I mean in the browser, you dork :P
23:34 < kanzure> i see
23:34 < CryptoQuick> important!
23:34 < CryptoQuick> but yes, actually, this could meet a couple ends, I suppose
23:34 < kanzure> i think i used pyjs once
23:34 < CryptoQuick> I mean, if we create a nice tidy working CAD kernel, in python, it could be used with PyJS...
23:35 < CryptoQuick> and also be used for your needs whatever they might be on the desktop
23:37 < kanzure> well, my idea for lolcad was to have a client that was just an interpreter
23:37 < kanzure> and then a window would show the changes in real time
23:38 < CryptoQuick> a python interpreter?
23:38 < kanzure> yeah
23:38 < CryptoQuick> so, same workflow as OpenSCAD
23:39 < kanzure> except without the inherent UI coupling
23:39 < kanzure> autocad has autolisp.. so why not a modern scripting language
23:39 < kanzure> heekscad has heekspython actually
23:39 < CryptoQuick> and then I could do as others have done with OpenSCAD, tacking on a UI
23:41 < kanzure> yeah
23:42 < CryptoQuick> well, why hasn't this nice simple tidy cad kernel been made yet, kanz? :P
23:42 < kanzure> because i'm busy as all hell and nobody's been buggng me
23:43 < kanzure> bugging
23:43 < CryptoQuick> well shit dude
23:43 < CryptoQuick> >:T
23:47 < CryptoQuick> kanzure: we need to set up some administration infrastructure first, if you don't mind.
23:47 < CryptoQuick> where are we putting our code, where are we keeping documentation, that sort of thing.
23:47 < CryptoQuick> I know you have answers to this already, but Google is being less than helpful.
23:47 < kanzure> how about lolcad.git
23:47 < kanzure> what username would you like
23:48  * CryptoQuick <--
23:48 < kanzure> ok one sec
23:48 < kanzure> username?
23:48 < kanzure> oops
23:48 < kanzure> email?
23:48  * CryptoQuick <-- @gmail.com
23:51 < kanzure> ok your username is crpytoquick@diyhpl.us
23:51 < kanzure> see pm for password
23:51 < CryptoQuick> did you really spell it like that?
23:51 < kanzure> fuck
23:51 < kanzure> um..
23:51 < kanzure> no
23:51 < kanzure> i spelled it right
23:51 < CryptoQuick> cool :)
23:54 < CryptoQuick> so, uhm
23:54 < CryptoQuick> I ssh into this or no?
23:55 < kanzure> yep
23:55 < kanzure> ssh cryptoquick@diyhpl.us
23:55 < CryptoQuick> yeah
23:55 < CryptoQuick> I figured it out now
23:55 < CryptoQuick> :P
23:55 < kanzure> don't tell me you don't.. know how to use ssh
23:56 < CryptoQuick> haha, I was having a derp moment, shut up
23:57 < CryptoQuick> passwd changed~
23:57 < kanzure> oh shit.. i screwed up
23:57 < kanzure> i meant to type newuser, did adduser instead
23:57 < kanzure> oh well. you can have a full account..
23:58 < kanzure> newuser sets you up on pinyshell, a hosting service for community git
23:58 < CryptoQuick> buh
23:58 < CryptoQuick> do what you must to fix it :P
23:58 < kanzure> nah go ahead
23:58 < CryptoQuick> ?
23:58 < kanzure> just don't abuse the box i'm not made of political power
23:59 < CryptoQuick> i'll try not to put cp on it
23:59 < CryptoQuick> but no guarantees
