05:20.02Notify03BRL-CAD:brlcad * 59742 brlcad/trunk/regress/repository.sh: add two more tests for bio.h and bin.h redundancy header inclusions. there's a lot of hits now, so don't make them be failures until they can be sorted out.

06:15.22Notify03BRL-CAD:brlcad * 59743 brlcad/trunk/src/libtclcad/tclcadAutoPath.c: nobody paying attention, these includes for itcl.h and itk.h are no longer necessary. once upon a time, functions were being called. now, they just pull a version, which is set in the config header.
06:18.09Notify03BRL-CAD:brlcad * 59744 brlcad/trunk/src/libtclcad/CMakeLists.txt: that means we no longer need to specify our bundled include directories in order to gain access to private/internal Tcl/Tk headers used by incrTcl.. we can eliminate them and simplify the build.

12:30.14starseekerhrm.  bitv.c:639:5: error: ISO C90 forbids variable length array ‘abyte’
12:32.06starseekerlittle surprising, since the definition is char abyte[BITS_PER_BYTE + 1];
12:33.02starseekerBITS_PER_BYTE is #defined in bu.h... what qualifies it as a vla?

16:18.20masterkorp*hello
16:25.49masterkorpI want to start designing a Power Take Off Unit, for my Nissan Patrol and eventually a PTO winch
16:26.34masterkorpDoes brlcad has some stress testing ?
16:26.59masterkorpi would like to make some simulations before making some prototypes
16:52.17starseekerO.o http://www.cs.uoi.gr/~fudos/smi2013.html
16:56.27masterkorpAlso i like to keep my CADs under git
16:56.44masterkorpany recomendations or advices i shall have about that ?
16:56.53starseekermasterkorp: are you thinking FEM stress modeling?
16:57.19masterkorpyes, on the long run
16:57.42starseekerwe don't have support for that in BRL-CAD, unfortunately
16:58.26masterkorpawww
16:58.43masterkorpi am currently using openscad
16:59.20masterkorpand I am strugling to finding finite element apss
16:59.28starseekeryou might check out something like http://www.salome-platform.org...
17:00.21masterkorphttp://www.calculix.de/
17:00.26masterkorpi found calculix
17:00.36starseekerhttp://opensourceecology.org/wiki/Finite_Element_Analysis
17:02.31masterkorphttps://en.wikipedia.org/wiki/List_of_finite_element_software_packages
17:02.41masterkorpfunny that salome does not show here
17:02.56starseekersalome uses other solvers
17:03.08starseekerdunno if it'll do what you want, but that'd be where I'd start looking
17:04.14masterkorpdoes salome allos import of STEP files and such ?
17:04.44starseekerI believe it can import STEP files
17:05.16masterkorp"Create/modify, import/export (IGES, STEP, BREP), repair/clean CAD models"
17:05.19masterkorpsweet thanks
17:05.27masterkorpso i can use my current openscad models
17:05.32masterkorpthank you

17:18.28starseekerOut of curiosity, does this relate in any way to the web-based CAD work our guys are doing?  https://github.com/bjnortier/shapesmith.next
17:24.31starseekeradds SolveSpace to his list of interesting looking things that are GPL only... http://solvespace.com/index.pl
17:30.38starseekerrecent work... might be worth discussing with him whether he considered using gecode
17:48.39starseekerdev who did this would also be interesting to talk to:  http://free-cad.sourceforge.net/SrcDocu/dir_fb1c9c07e71953aeebae47afc0fb8941.html

20:37.03brlcadstarseeker: no problems whatsoever building with tcl/tk 8.6
20:37.57brlcadbut looks like there is some disconnect between itcl and tcl
20:38.13brlcadmain windows come up fine, but any itcl window is crashing
21:48.06Notify03BRL-CAD:starseeker * 59752 (brlcad/trunk/include/raytrace.h brlcad/trunk/src/librt/db_fullpath.c): Add a function that allows for extra information to be printed when converting full paths to strings. So far, can print out boolean ops and object types. Currently useful for debugging, but it may prove to have other uses as well.
21:55.52Notify03BRL-CAD:starseeker * 59753 (brlcad/trunk/NEWS brlcad/trunk/doc/docbook/system/mann/en/search.xml brlcad/trunk/src/libged/search.c): Add a -v option to print more information in the full path reporting strings for search. This is primarily intended as a debugging tool to allow easy examination of the properties of the results that satisfied a given set of search filters.
21:56.19starseekerbrlcad: system itcl/itk, or our copy?
21:56.37starseekerfrom what I recall, 8.6 had its own newer version of itcl/itk

23:32.28starseeker``Erik: er, yeah ;-)
23:32.57starseeker``Erik: how goes it?
23:33.11``Erikd'no if we have it, but it's not too difficult... "mark&sweep" is a fairly common approach

23:33.41starseekerthat's not good

23:34.14starseekergot it just in time for all the snow and ice eh?
23:35.12``Erikyeh, county has decided that it doesn't even need snow to cancel the last couple weeks, so not only have I been sick, I've been at home with a 6yo, who was also sick for part of it :/

23:38.36``Erikmakes me miss seattle :)
23:38.50starseekerwell, at least we do get sunshine from time to time...

23:40.47``Erikgsoc can be a sapping experience, I'd think if BRL-CAD were purely volunteer, there'd be a lot more deliberation before applying

23:42.39starseekerah, not a ploy
23:43.31``Eriknah, I'm not terribly interested in the latest model... if I'm coding, I kinda want to be using the oldest weakest model I'd target, just to make sure it runs ok there
23:44.31``Erikd'no if you watch the news articles, a game called "flappy bird" is the hot new thing, incredibly trivial, yet makes $50k/day O.O insane stuff
23:44.50``Erikbut the long tail falloff is very aggressive, #1 and #2 make money, #5 loses
23:45.07starseekercan't help thinking that's kind of a lottery - still have no clue why Angry Birds took off
23:45.25``Erikit is
23:45.59starseekershould probably read some research on why certain things "go viral"
23:46.21starseekernot entirely sure I *want* to know, but still...
23:49.52``Erik'viral' is a strange thing... rovio put out several dozen games before they did angry birds... notches first solo game was minecraft... it doesn't seem very predictable, but there're many models to hindsight it

23:56.59``Erik12 hour day? O.o
23:58.00starseekernot quite
23:59.04starseekeris getting closer to a point where some things "click" and good stuff happens - keeps you pushing
