| 00:00.54 | kanzure | was that just because someone bulk downloaded papers? |
| 00:01.32 | starseeker | no, you're probably thinking of JSTOR and Aaron Swartz |
| 00:02.00 | kanzure | i'm familiar with aaronsw's work, but i specifically remember something about the reason for nasa taking down their server was something about "china" and "downloads" |
| 00:04.00 | kanzure | maybe not. |

| 00:05.18 | starseeker | that what you're thinking of? |
| 00:05.33 | kanzure | tbh i got the "china" information second-hand from a person heh |

| 11:01.13 | ncsaba | anybody around who knows the pipe.c code ? |
| 11:15.00 | ``Erik | if there isn't, there will be... ask your question and hang around until someone responds :) |
| 11:43.32 | ncsaba | well I would like to ask about the meaning of the fields of the bend_pipe structure |
| 11:45.52 | ncsaba | I suppose "bend_V" is the center of the circle with radius "bend_radius", of which the bend's center line is part of |
| 11:48.56 | ncsaba | what I'm actually after is if there is any of those parameters helpful to get a unit vector from the bend's center (as I understand it) pointing to the middle of the bend ? With "middle" I mean the mid-point of the center-line of the torus segment |
| 12:06.11 | ncsaba | ok, I think I will use: VCOMB2(cp, bend->bend_start, 0.5, bend->bend_end, 0.5); VSUB2(cp, cp, bend->bend_V); VUNITIZE(cp); |

| 12:41.14 | ncsaba | brlcad: isn't "bend_ra" the vector from bend_V -> bend_start ? |
| 12:41.52 | ncsaba | I need one from bend_V to the middle point between bend_start and bend_end (if I understand the meaning of these correctly) |
| 12:43.43 | ncsaba | this is for the centroid - I managed to understand the math behind it, solved my integrals, and then took what you suggested originally and calculate the centroid of the center line of the torus segment :-) |
| 12:47.19 | ncsaba | so if my math is correct, the centroid sits on the line from the bend's center to the middle of the center line, at distance cos(bend_angle/4)*(bend_radius + bend_or) |
| 12:48.00 | ncsaba | sorry, was wrong: cos(bend_angle/4)*bend_radius |

| 20:28.06 | hawthorn | oh sorry |
| 20:28.16 | tofu | no need to be sorry either, relax ;) |
| 20:28.28 | hawthorn | actually I was interested in the reduction of code duplication project |
| 20:28.37 | tofu | great |
| 20:28.39 | tofu | why? |
| 20:28.53 | hawthorn | gsoc project |
| 20:28.58 | tofu | I know |
| 20:29.04 | tofu | why do you want to work on code reduction? |
| 20:29.26 | hawthorn | actually i am interested in OOP |
| 20:29.40 | tofu | what's that got to do with code reduction? :) |
| 20:29.40 | hawthorn | so code reduction can be achieved by it |
| 20:29.45 | tofu | hmm. |
| 20:29.53 | hawthorn | it falls under my interest thats it |
| 20:30.01 | hawthorn | am i wrong ? |
| 20:30.28 | tofu | code refactoring can lead to better introduction of OOP |
| 20:30.37 | tofu | OOP in general however rarely leads to reduced code |
| 20:31.05 | hawthorn | oh.. |
| 20:31.20 | hawthorn | thank you for that |
| 20:31.30 | tofu | obviously code reduction can be achieved by refactoring … which can lead to better OOP design … they're just not necessarily the case :) |
| 20:31.33 | hawthorn | but is that project allotted to someone ? |
| 20:31.38 | tofu | that's not how it works |
| 20:31.47 | tofu | you propose a project |
| 20:31.52 | tofu | others propose a project |
| 20:32.06 | hawthorn | i am new |
| 20:32.07 | tofu | the strongest candidates (based on a whole slew of criteria) are selected |
| 20:32.13 | hawthorn | i dont know how to get a project |
| 20:32.29 | tofu | ultimately, it's YOUR project |
| 20:32.35 | tofu | you propose to do something |
| 20:32.49 | hawthorn | ok. |
| 20:32.56 | hawthorn | so I have to propose something new ? |
| 20:33.01 | tofu | that can be an idea from our ideas page, some variation, or something else altogether |
| 20:33.19 | hawthorn | ok .. |
| 20:33.22 | tofu | regardless of what it is, your job is to flesh out the idea with lots of detail |
| 20:33.43 | tofu | so we might suggest working on "code refactoring" for example |
| 20:34.28 | hawthorn | oh.. |
| 20:34.31 | ``Erik | hawthorn: we have an ideas page, but they're just ideas... you can propose what ever you want, several people can propose the same idea, you can do proposals for several ideas... it's not a "pick one and get assigned" thing at the moment |
| 20:34.34 | tofu | but then you'd turn that into a much more specific proposal to perhaps refactor all of our geometry converters into a library, or finding all the places where we iterate over geometry types manually and push those up into the primitives OOP style, or something else etc |
| 20:34.58 | hawthorn | so I have to present some idea related to code refactoring and then if you like it you will assign me that project..is it like this ? |
| 20:35.11 | tofu | mm, first patch received |
| 20:35.39 | tofu | vladbogo: thanks, someone will usually look at it in a few days |

| 20:36.40 | ``Erik | been seeing cyclic routing tables, too... might be a ddos causing screwy failover behavior, or fat fingers in very expensive router rulesets |
| 20:37.23 | tofu | yeah, I've been reading news reports that there are several unprecedented DDoS attacks going on across the net right now |
| 20:37.40 | ``Erik | (fwiw, vladbogo has also been helping answer questions in chan) |

| 20:38.07 | tofu | hawthorn: you and everyone else.. ISP is on fire |
| 20:38.43 | hawthorn | I am also very much interested in computer graphics |
| 20:39.07 | hawthorn | so can some small game can be made ? : |
| 20:39.26 | tofu | hawthorn: you can propose pretty much anything |
| 20:39.36 | tofu | I'd suggest discussing any idea in here in detail |
| 20:39.48 | tofu | like if you wanted to make a small game, how would it involve brl-cad? |
| 20:40.08 | vladbogo | tofu: thanks, I will wait for the review |
| 20:40.28 | tofu | and thanks for helping others, that means a lot |
| 20:40.31 | hawthorn | yaa..that would be an issue |
| 20:40.40 | hawthorn | i know OpenGL |
| 20:41.20 | tofu | hawthorn: if you wanted to work in that area, you might check out what the blender folks did X years ago for their game engine, you could propose creating something similar for BRL-CAD |
| 20:41.52 | tofu | but know that would be a stretch to fit into GSoC timeframe given you have very limited experience (at least with BRL-CAD), don't know about your API design background |
| 20:42.39 | tofu | there's certainly tons of games that could be implemented using brl-cad geometry and rendering under the hood |

| 20:50.10 | hawthorn_ | i will first install BRL-CAD, have a look at it and then i ll ping you with some possible ideas |
| 20:50.18 | hawthorn_ | thank you btw |
| 20:50.54 | tofu | excited to hear what you might come up with |
| 20:51.42 | tofu | as soon as the webserver is back up, I'd suggest taking a look over our top-listed projects to see if/how any of them might be interesting too or see if we can brainstorm something based off those ideas |
| 20:51.58 | hawthorn_ | actually i also wanted to ask that how many projects have you already selected ? ..if you could tell |
| 20:52.01 | tofu | it's helpful to consolidate effort in as few areas as possible so real useful progress is made |
| 20:52.08 | tofu | we haven't selected any |
| 20:52.19 | hawthorn_ | oh.. |
| 20:52.21 | tofu | the application timeframe hasn't opened yet, there are no official submissions |
| 20:52.27 | tofu | see the timeline on the GSoC site |
| 20:52.34 | tofu | you're good and early, that's a really good thing |

| 20:52.50 | hawthorn_ | but we can make proposal now right ? |
| 20:53.08 | tofu | we don't start making selections until after the submission window *closes* |
| 20:53.10 | tofu | absolutely |
| 20:53.22 | tofu | several have already put up some text on our wiki and mailing list for review |
| 20:53.34 | tofu | see our checklist (again, when the website is back up) |
| 20:54.22 | tofu | looks like it happens to be up right this second |
| 20:54.23 | ``Erik | looks like the server may be semi-connect for now |
| 20:54.35 | hawthorn_ | so till 21st we just have to discuss the application ideas |
| 20:54.45 | hawthorn_ | selection process would be afterwards ..right ? |
| 20:55.11 | tofu | proposals can be discussed and modified right up to the submission deadline |
| 20:55.48 | hawthorn_ | ok ..so if I cannot come up with a good proposal by 21st, can i propose something after 21st ? |

| 20:56.35 | tofu | but I hope you hang around and keep discussing |
| 20:56.37 | hawthorn_ | yup.. |
| 20:56.39 | tofu | the more you discuss and research, the better your chances will be |
| 20:56.55 | hawthorn_ | currently having my end semester exams |
| 20:57.13 | tofu | another page of ideas: http://brlcad.org/~sean/ideas.html |
| 20:57.24 | tofu | needs to update that list with some that are completed now |
| 20:57.27 | hawthorn_ | so it is difficult for me to manage time till 25th |

| 21:01.20 | rays2pix | Hi ..this is Deepak GSoC aspirant. I am working on converting the bwfilter utility in to libicv functions. Its not quite complete. Would like to send it across to the group |
| 21:01.52 | rays2pix | Is it okay to send it that way? |
| 21:06.04 | hawthorn_ | hello |
| 21:06.19 | hawthorn_ | i ll come back tomorrow with an idea |
| 21:06.44 | hawthorn_ | thank you tofu for your support |
| 21:06.51 | hawthorn_ | see you tomorrow |
| 21:10.25 | ``Erik | rays2pix: you can always send a link to the patch... but if it's not complete and no specific questions are posed, it might be ignored. A completed patch should be uploaded to the sourceforge tracker, and that will be looked at hopefully within a few days of upload |
| 21:10.46 | tofu | hawthorn_: we're kind of keen on C/C++, but it really depends on what you propose to work on |
| 21:11.16 | hawthorn_ | yaa i am very good in C and C++ |
| 21:11.42 | hawthorn_ | i can do some good coding in these |
| 21:11.59 | rays2pix | Erik: thanks. I will goahead and come up with patch and questions |
| 21:12.04 | tofu | rays2pix: yeah, what he said .. it takes a lot of effort to review a patch, especially for the first time so it should be as good as you can make it (without being late) |
| 21:12.55 | tofu | if you need help putting the patch together, pastebin.ca code snippets and/or ask questions as you need to here |
| 21:22.44 | hawthorn_ | proposal of ideas can continue after the 21st..? |
| 21:22.48 | hawthorn_ | please confirm |

| 22:20.42 | tofu | excellent, glad to hear it |
| 22:20.59 | tofu | is that your main interest or do you have a backup too? |

| 23:09.59 | starseeker | wonders if we could switch to a maintained regex library like pcre and use their pcreposix.h instead - with any luck it wouldn't have the same conflict issues with system regex functionality, and someone else is actively maintaining it... |
