01:43.58 hcurtis I've been trying to get my dynamic allocation program to use BRL-CAD headers. The commands I am using, the error message I am getting, and my program are here: http://paste.lisp.org/+3276/1 I am working on solving the problem, but comments and advice are welcome.
04:56.02 hcurtis Update: I've been trying to get my dynamic allocation program to use BRL-CAD headers. I had to reboot and rebuild because my computer was going really slow, but I was able to get back on track. I solved some previous problems, but I now have a new error message to handle. Here are the commands I am now using, the error message, and the current version of my program: http://paste.lisp.org/+3277

11:39.26 Zhao_Anqing hi, excuse me. I hope to ask a question about rt_db_internal's member 'idb_ptr'. I see it can point to almost everyting. e.g. rt_comb_internal, model, rt_bot_internal, or so on.
11:41.52 Zhao_Anqing What is exactly the funtionality of it? It seems about database storage.

12:31.03 ``Erik Zhao_Anqing: it is about internal database storage, it's a pointer (ptr) to the internal (i) database (db) :)
12:36.03 Zhao_Anqing ``Erik. OK. I see. Thank you so much.

17:03.03 raj12lnm_afk hi all.
17:03.30 raj12lnm mged offers 3 types of modes for BOT geometry
17:04.29 raj12lnm but rtgeom.h also has a definition of "RT_BOT_PLATE_NOCOS" as a mode
17:04.44 raj12lnm although it is same as BOT with some differences
17:05.00 raj12lnm but mged doesnt have an option to accomodoate this,
17:05.02 raj12lnm Is it required ?
17:05.23 raj12lnm javampire : thanks for your help today on skype :)\
17:05.33 raj12lnm I was able to hack it and it works.
17:05.54 raj12lnm javampire : Now I am off to modularizing the class for different modes.
17:05.56 javampire raj12lnm: welcome !
17:06.02 javampire cool, thanks !
17:06.14 raj12lnm javampire : you can see the code :)
17:06.31 raj12lnm here it is
17:06.31 raj12lnm https://github.com/raj12lnm/python-brlcad/commit/ab57e62db457b18b283636ba436e88348b1ec850
17:06.37 javampire raj12lnm: I guess you can skip NOCOS for the moment
17:06.45 javampire I have seen it, looks good
17:06.49 raj12lnm javampire : ok :)
17:09.36 raj12lnm javampire : but i am afraid to implement faces as a different class.
17:09.41 raj12lnm the reason being
17:09.42 javampire why ?
17:10.04 raj12lnm in the other two modes (surface and solid) the face dont have thicknesss and face_mode
17:10.11 raj12lnm so two entries going futile.
17:10.41 javampire yes, you can implement a base face without thickness and mode, and extend it with a ThickFace class or similar
17:11.00 javampire then create the right face
17:11.27 javampire look at the Sketch with it's different Curve sub-types
17:11.36 raj12lnm and all of them in the same file bot.py.
17:11.41 javampire yes

22:47.01 clock does anyone work with mechanics physically or only in 3D modelling?
23:13.41 ``Erik I think I saw a wrench, once O:-)
23:21.11 clock sounds like you don't
23:39.11 ``Erik other than working on my car or truck and minor stuff around the house, no, I don't... I believe archivist was doing watchmaking? ronja was a big hit because it was one of the rare physical things :)
23:42.03 clock what u mean ronja was a big hit?
23:42.09 clock have you built ronja?
23:42.52 clock ``Erik, im thinking about making open source small paper bags for making order in small components like electronic components or nuts and bolts
23:42.56 ``Erik no, but we all thought it was cool and talked about it to others :)
23:42.58 clock ``Erik, what do you think about it?
23:43.05 clock oh :)
23:43.12 clock ``Erik, archivist is from the same place?
23:43.16 clock thanks :)
23:43.21 ``Erik I can't parse that sentence about components
23:43.44 clock im thinking about making open source small paper bags
23:43.55 ``Erik no, archivist isn't, but he(?) has made comments that lead me to believe he does watchmaking or something similar
23:44.05 ``Erik like kits for small projects?
23:44.08 clock small paper bags for storing small components
23:44.17 clock small components like eletronic components or nuts and bolts
23:45.02 clock ``Erik, kits for small projects too
23:45.07 clock How I came to the idea
23:45.16 clock I wanted to do some very simple electronic experiment
23:45.32 clock but I realized the box with resistors is a total mess
23:45.47 clock and finding a particular value takes basically sifting through all
23:46.04 clock some of that was already sorted in small bags
23:46.15 clock and something was like in strips from reels
23:46.24 clock but the resistors fall out of these strips and pool at the bottom
23:46.33 clock and the strips are not labeled with value or its very ilegible
23:46.44 clock so I wanted to put every value into separate small bag
23:46.48 clock but I dont have those bags
23:46.59 clock and in grocery store the smallest closeable plastic bag I can buy is 1 L
23:47.25 clock I am sure someone somewhere in the internet is selling small reclosable plastic bags
23:47.57 ``Erik I have something like http://ecx.images-amazon.com/images/I/51MsiS9HyjL._SL500_AA300_.jpg that I use for that
23:48.48 ``Erik I've seen people use tackle boxes for that purpose, as well
23:48.52 clock OK I don't have enough place in my tiny apartment for that
23:48.57 clock plus they don't scale
23:49.21 ``Erik http://www.nhbm.org/wp-content/uploads/2012/06/Tackle-box-stuffed-full-1024x768.jpg
23:49.21 clock what do you do when the drawer labeled 25 k is suddenly full?
23:49.45 clock again, fixed structure, fixed partitioning
23:50.09 ``Erik have 2 25k drawers? :D
23:50.16 clock ``Erik, yes in my country and here its standard practice too
23:50.25 clock ``Erik, OK and how do you do that?
23:50.48 clock and I dont want 2 drawers of the same kind for anything
23:50.50 clock I think its unsystematic
23:51.00 clock I want a bigger drawer
23:51.06 clock a bag can adjust its volume to the contents
23:51.41 clock ``Erik, funny is also when you accidentally kick the tackle box
23:51.46 ``Erik *shrug* true, I've not run into an issue myself
23:51.51 clock all the things jump out and mix together
23:52.00 clock bags don't have this problem
23:52.09 clock you can also take bags out and take them with you
23:52.13 ``Erik oh, I've knocked over my parts thing and had drawers come out, that sucks, but it's rare
23:52.19 clock tried to take 20 drawers out and throw them into your backpack?
23:52.30 clock how organized were the contents after arriving to the destination place?
23:53.11 clock ``Erik, and I guess if you need to store one long element
23:53.17 clock you take tin cutters
23:53.31 clock take out the bottom 4 drawers
23:53.34 clock cut out the partitions
23:53.45 clock cut out the sides of the drawers and scotch tape them together
23:53.52 clock and make 1 wide drawer?
23:54.08 clock Or maybe you drill a hole in the backside of one drawer and the box itself?
23:54.22 clock and through the wall the box is at?
23:54.27 ``Erik http://m.globalindustrial.com/m/p/storage/bins-totes-containers/compartment-storage-boxes/large-plastic-compartment-box-adjustable-w-20-dividers has adjustable partitions
23:54.32 clock see? this box has infinite possibilities of flexibility! :)
23:54.51 clock I know these dividers
23:54.58 clock the resistors get under them
23:55.04 clock so you cannot press them completely anymore
23:55.17 clock and this allows more resistors to get under the dividers in an avalanche effect
23:55.27 clock press them down completely anymore
23:55.33 clock and also still suffering from the kick effect
23:55.51 clock and turning the thing upside down will mix the thing because the lid doesn't fit perfectly and things fit through the gap
23:56.25 clock BUt I guess these things may work well in a advert!
23:57.06 ``Erik http://i.walmartimages.com/i/p/00/02/57/00/00/0002570000391_500X500.jpg ? :D
23:57.37 clock yes this is exactly what I use!
23:57.43 clock except the zipper is double
23:58.06 clock I needed to organize a storage area with 600 kg of material replacement parts and tools for a chain of 6 gyms
23:58.22 clock in places they had plastic storage boxes
23:58.32 clock which had the property that they crack and are expensive
23:58.51 clock I selected the solution called "discarded cardboard vegetable crates"
23:59.32 clock they are stackable. They are durable. On impact they don't crack but dent. They have cutouts for carrying. They cost nothing. They come in various sizes.
23:59.44 clock And the restaurant in whose backyard I took these was like 50 m away
