| 15:52.38 | keldwud | but yeah, it was weird that they had armed guards but then told me that everything there was internal, no outside clients |
| 15:52.39 | levi | jxqz: Technically, it's sample points along a curve along with all the derivatives of the function defining the curve at those points. |
| 15:52.58 | levi | jxqz: But the method only uses the first derivative. |
| 15:53.01 | keldwud | hey, anybody wanna go to lava hot springs or jackson hole sometime in the next couple weeks? |

| 15:56.01 | levi | jxqz: It allows you to reconstruct the curve, so long as your samples are of sufficient resolution. Which means you can recreate both smooth and sharp surface details from voxel data, rather than just rendering them as cubes. |
| 15:56.31 | jxqz | so, a 2xn matrix \begin{bmatrix} x_1&\cdots&x_n \\ \deriv{f,1}{x}|_{x=x_1}&\cdots&\deriv{f,1}{x}|_{x=x_n} \end{bmatrix} |
| 15:56.59 | levi | It's a dual method because the vertices of the resulting surface mesh are on points interior to the voxel grid cells rather than on the voxel grid itself. |

| 16:14.14 | levi | The trouble with learning mathematical stuff is that it's very precise, so the mathematicians invent new words to talk about new things, and so you have to learn the vocabulary along with the concepts or you just get totally lost. |
| 16:20.14 | jxqz | like diffeomorphism, homeomorphism, homomorphism, holomorphism, homotopism |
| 16:20.15 | jxqz | etc. |
| 16:20.59 | jxqz | for about 2 months in my 2nd semester of topology, I thought that homeomorhism and homomorphism were the same thing |
| 16:21.12 | eightyeight | i thought the same thing as well |
| 16:21.28 | jxqz | isomorphism, endomorphism |
| 16:21.48 | eightyeight | topological isomorphism |
| 16:22.15 | keldwud | gah, I feel so pleeb with all this topographical talk |
| 16:22.29 | eightyeight | topography != topology |
| 16:22.30 | keldwud | now I want to finish my maths |
| 16:22.34 | keldwud | gah |

| 16:22.38 | keldwud | facepalms @ self |
| 16:22.46 | keldwud | yes I meant topolog |
| 16:22.56 | keldwud | runs and hides himself in khanacademy |
| 16:23.02 | eightyeight | when trying to explain topology to my family, the first response was something like "so, maps?" |
| 16:23.08 | jxqz | point-set topology, blah, blah |
| 16:23.09 | keldwud | lol |
| 16:23.22 | keldwud | .define topo |
| 16:24.03 | keldwud | the study of regions, right? |
| 16:24.24 | eightyeight | study of shapes and spaces, mostly |
| 16:24.42 | jxqz | keldwud: you can think of topology as a kind of generalization of geometry |
| 16:24.52 | levi | Topology is sort of an abstract look at what makes things a certain shape. |
| 16:25.14 | eightyeight | it doesn't help that topology can be applied to things like subway maps either |
| 16:25.17 | eightyeight | heh |
| 16:25.36 | keldwud | I can't wait 'til I get to topology |
| 16:25.37 | jxqz | but by shape, there is an implicit acknowledgement of multi and/or micro dimensions |
| 16:25.45 | jxqz | etc. |
| 16:25.46 | keldwud | the few times I've heard of it, I've been excited |
| 16:25.57 | eightyeight | IE: the ability to preserve the location of the stops, distance and the order, after morphing the shape, |
| 16:26.15 | levi | It's definitely interesting stuff, although I only know a little about it. |
| 16:26.18 | jxqz | eightyeight: well, I think the subway map has to do with how a graph can be embedded into a surface? |
| 16:26.21 | eightyeight | without it being ultra-realistic, possibly making the text on the stops difficult to read |
| 16:26.22 | keldwud | because isn't topology kind of the foundation of how we perceive the universe? |
| 16:26.33 | eightyeight | jxqz: indeed |
| 16:26.43 | keldwud | i.e., we perceive shapes but those are only an expression of an underlying "thing" |
| 16:26.47 | jxqz | keldwud: what is a torus? |
| 16:26.56 | keldwud | isn't a torus an inside out sphere? |
| 16:27.03 | keldwud | kind of like a donut |
| 16:27.06 | jxqz | topology has a far, far more abstract and complete answer |
| 16:27.13 | keldwud | it looks like a donut but it isn't |
| 16:27.21 | keldwud | kind of like a tesseract looks like an inside out square? |
| 16:27.22 | jxqz | a torus is the surface of a donut |
| 16:27.26 | keldwud | oh ok :) |
| 16:27.47 | levi | Topology: The mathematical branch that brought you moebius strips and klein bottles! |
| 16:27.52 | jxqz | but to a topologist, that's only a torus that is embedded in 3-space |
| 16:28.08 | keldwud | jxqz: yeah, that's why I was thinking it was more similar to a tesseract |
| 16:28.21 | keldwud | because it mathematically expresses itself in more than three dimensions, no? |
| 16:28.29 | keldwud | but yeah, I'm excited to get into topology, I just need to catch up on my maths. I still haven't done calc. |
| 16:28.35 | keldwud | I'm only at college algebra |
| 16:28.38 | unum | oddly I'm feeling really happy I'm done with school :) |
| 16:28.49 | jxqz | keldwud: the torus exists outside of any dimensional context |
| 16:28.58 | keldwud | jxqz: ahh, ok. that makes more sense |
| 16:29.16 | keldwud | but for us to perceive it, we see a donut type shape |
| 16:29.30 | levi | A coffee cup is also a torus, though. |
| 16:29.56 | keldwud | runs back to khan academy to start catching up |
| 16:30.15 | levi | Or at least the are homeomorphic. |
| 16:30.17 | jxqz | ok |
| 16:30.23 | jxqz | start here: |
| 16:30.41 | jxqz | there are 4 unique ways to identify the sides of a square |
| 16:30.52 | jxqz | 1) a 2-sphere |
| 16:31.09 | jxqz | 2) a moebius surface |
| 16:31.15 | jxqz | 3) a torus |
| 16:31.22 | jxqz | 4) a projective plane |
| 16:31.53 | jxqz | figure out what all of that means, and you've got a good cross section of intro-to-topology |
| 16:34.01 | levi | jxqz: You looked at Homotopy Type Theory at all? |
| 16:35.28 | levi | I recently skimmed through a very interesting book on computational geometry. |
| 16:37.16 | jxqz | levi: yes |
| 16:37.39 | jxqz | I have a makefile question: if I have as part of the rules for the target |
| 16:38.03 | jxqz | `for i in "a b c d" ; do echo ${i} ; done`, it doesn't work |
| 16:38.07 | levi | Oh! To tie things together... you can optimize construction of a sparse voxel octree by sampling your geometry in the pattern of a space-filling curve, such as in the Morton order or in the order of a Hilbert curve. |
| 16:38.24 | jxqz | I mean, the variable ${i} isn't getting figured out |
| 16:40.40 | levi | jxqz: Probably a field separator problem? |
| 16:41.54 | levi | You need IFS to include the space character, I think. |
| 16:55.24 | jxqz | levi: that's awesome |
| 16:55.35 | jxqz | about the space filling curve pattern, I mean |
| 16:59.59 | levi | Morton ordering (Z-order curve) is basically a linearization of a depth-first traversal of the n-dimensional variant of a quadtree/octree. |
| 17:00.51 | levi | And the cool thing about it is that the index of an element is the bitwise interleaving of its coordinates in that n-dimensional space. |

| 17:24.20 | levi | Time, and space. |
| 17:25.34 | levi | Well, it's space-efficient for a fully-populated (or nearly so) tree. |
| 17:25.55 | levi | And lookup by coordinates is O(1). |

| 17:26.36 | youtah | old but classic |
| 17:26.54 | levi | And you get storage locality of spatially-local samples. This lets you do out-of-core construction of sparse trees on huge data sets. |
| 17:28.36 | jxqz | levi: since there is a (spacetime) optimization involved, do you know if the lagrange method is used at all? |
| 17:29.04 | jxqz | is curious about functional analysis-based optimization methods not involving Lagrange |
| 17:29.55 | jxqz | where lagrange multipliers and the lagrangian operator are basically two topics within the same methodology |
| 17:30.15 | jxqz | levi: or functional analysis at all |
| 17:30.20 | levi | And if your geometry is defined intensionally (vs extensionally) then you can sample it at arbitrary resolution and store the contours you care about in a sparse octree without ever having to build the entire dataset of samples in-core. |
| 17:30.44 | jxqz | although I cannot imagine an optimization problem that *cannot* be cast into the form of a functional analysis problem somehow anyway |
| 17:30.55 | jxqz | but that doesn't say much |
| 17:30.58 | levi | I'm not aware of any connection between Lagrange and Morton order. |

| 18:01.12 | jxqz | but it's equally annoying when programs are called by generic names |
| 18:01.40 | jxqz | like 'document viewer', what the heck is that? Something that will view a 'document'? What is a 'document'? |
| 18:05.54 | jxqz | I think it comes down to a philosophical point |
| 18:06.57 | jxqz | when you rename a package to some generic name, you're implying that the package will restrict itself to stuff that's relevant only to what the generic name means |

| 22:28.39 | ldav15 | jxqz: So you want system-level macros? /etc/rpm/macros |
| 22:30.58 | ldav15 | rpm and rpmbuild also take macros via the --define flag |
| 22:37.32 | jxqz | ldav15: no, I want project-level macros |
| 22:38.10 | jxqz | it looks like the only way you can do that is with --define, or %global in the spec file |
| 22:38.20 | jxqz | that might be the best way to do it |
| 22:38.22 | jxqz | actually |
| 22:38.42 | jxqz | keeping the macros in the spec file will reduce the number of files |
| 22:38.44 | ldav15 | I use --define for those. |
| 22:39.31 | ldav15 | I do keep some ithe spec file as well. |
| 22:39.45 | jxqz | I also would personally prefer ~/.config/rpm/macros instead of ~/.rpmmacros, but I might just be more standards oriented than the average programmer |
| 22:45.01 | ldav15 | The way I've got my stuff set up, I have my CI server inject some stuff like _topdir, _build and _host via --define. The rest is in the spec file. |
| 22:46.45 | jxqz | what's a CI server? |
| 22:48.37 | ldav15 | continuous integration |
| 22:48.46 | ldav15 | in this case Jenkins |
| 22:49.06 | jxqz | ooh, well, we're not that fancy here yet |
| 22:49.25 | ldav15 | It's basically dumping a bunch of variables into a shell script |
| 22:51.04 | ldav15 | which in turn invokes rpmbuild |
| 22:53.54 | ldav15 | Once set up it's kind of nice. It just polls version control and kicks off a new build if there's been changes. |
| 22:55.05 | ldav15 | Getting to that point was at times a bit twisted, since Jenkis seems to be setup mostly for Java builds. |
| 22:59.04 | jxqz | one of our guys is trying to get even just a cron job setup, but some of our code has to be build on winderz, so there's like these intermittent failures all the time |
| 23:05.33 | ldav15 | I know exactly what you mean. My setup was designed to work with Windoze also. That was the really twisted bit. |
| 23:38.37 | jxqz | ldav15: one of the things I was trying to do is make it so that I don't have to template the spec file, but it seems that this is going to be impossible |
| 23:40.04 | jxqz | wait, maybe I can pass in those values via --define anyway |
