02:44.58 learner so it is.. ;)
02:45.13 learner set the date to may 11 on the file
02:46.15 learner it goes by gmt by default
02:46.43 learner usually just match the source unless the files really are uploaded a day or two later
02:48.20 ``Erik erm, it's been the 12th in gmt for, like, 4 hours now... not the 10th... :)
02:49.30 ``Erik (sorry, 3 hours, not 4)
02:54.51 learner i know, that's what i mean.. i set it to match the Source release (which was on the 11th gmt)
02:55.29 learner otherwise it just pokes questions like yours..
02:55.54 learner i can hear it already.. "why did you wait a day to upload the freebsd files?! they should have been first!"

02:58.07 CIA-3 BRL-CAD: 03brlcad * 10brlcad/NEWS: fixed compilation support for Solaris.. Sparc 64 is improved, but probably needs more testing still
02:59.33 learner eww.. sleep already?!
03:38.20 narnia learner, any first hand experience with color laser printers?
03:39.24 narnia learner, any thoughts on this one: http://www.office.xerox.com/perl-bin/product.pl?product=8400&page=modl 8400/dp
04:31.43 learner yep
04:34.01 learner not a bad printer
04:34.10 learner nice price actually
04:35.18 learner have to be careful on the color toner expenses
04:36.39 narnia learner, this one is solid ink. (think crayons)
04:36.45 learner odd, though.. phaser used to be the brand of a really good waxjet company
04:36.52 learner wonder if they bought them out
04:37.34 narnia these are the former tektronics printers.
04:37.34 learner ahh, crayons.. then it is them
04:38.00 learner that's a thermal waxjet, not laser
04:38.59 learner those are/were good printers, i used a tek for years
04:39.55 learner it's rather high quality printing if it's related to the printing you need to do
04:40.01 learner you're going to burn through the black
04:40.42 narnia this is true
04:40.55 narnia my middle daughter has offered to purchase it.
04:40.59 learner and those "crayons" are definately not cheap
04:41.25 learner you could get a faster high-volume color hp for about the same probably
04:42.08 learner http://h10010.www1.hp.com/wwpc/us/en/sm/WF02a/18972-236251-236268.html
04:42.13 narnia Genuine Xerox Solid Ink 8400 Black (Six Sticks)6,800 pages$99.99
04:42.29 learner 1200 for double the volume and rate
04:45.09 learner the 4600 series is relatively "big", but it is nice and fast, decent quality printing
04:45.48 narnia Price: $155.99*HP Color LaserJet C9720A Black Print Cartridge (C9720A)
04:45.50 narnia Average cartridge yield: approx. 9,000* pages (black)
04:46.04 learner personally, given the choice for my own printing, I'd go with the wax jet just because the printing process is so much better (even if significantly lower resolution and slower)
04:46.15 learner but then I don't have thousands of pages to print
04:46.45 narnia ~155.99x3
04:46.53 narnia ~155.99*3
04:46.54 ibot 467.97
04:47.21 narnia ~99.00*30000/6800
04:47.22 ibot 436.764705882353
04:47.51 narnia roughly the same cost for black toner or crayon.
04:48.01 learner roughly
04:48.26 learner oh, they increased their ppms
04:48.26 narnia ~155.99*30000/9000
04:48.27 ibot 519.966666666667
04:48.50 learner that rebate gives it the edge
04:49.38 learner heck, go with the phaser :)
04:49.40 learner i'm jealous
04:49.40 narnia the crayon printout are better looking
04:50.15 narnia learner, you want to help me print out the 30000+ pages?
04:50.23 learner hmm.. i wonder what their 2400 finepoint technology is like for photography
04:50.38 learner you send me the printer to keep, and I'll print em for ya, sure ;)
04:51.53 learner heck, with os x 10.4 you can use the new automator to convert every email to a pdf and feed it to the printer in a massive unattended batch job
04:51.54 narnia this is really stupid printing out the 30000+ pages. there is no way they will read any significant part of it.
04:53.05 learner if it was 30k mime encoded gibbrish, that won't be more than a couple thousand rendered most likely
04:54.15 learner not that it's any better.. but will save more of the pretty phaser's life
04:57.13 narnia this is what is mainly on the cdrom. my job search is rather large. http://strauss.blauedonau.com/jobs-09aug2004.dir/
05:08.41 narnia this is exactly what is on the cdrom. the opposing lawyers printed out the html files.
05:09.05 learner interesting
05:09.51 narnia what is interesting?
05:10.13 learner just all the organization that you have going there
05:10.38 learner so it's probably more like 25000 pages after filtering out html header/footerness
05:10.41 narnia well i thought it would make sense to the lawyers and the judge.
05:12.29 learner i'll still be jealous if you get the phaser
05:12.42 learner digital photography and printing are a big hobby
05:13.24 learner i've yet to dish out for a high-quality printer.. i send high res images across the country and have them print on the big bad boys
05:14.49 learner ~200.0 / 6000.0
05:14.51 ibot 0.033333333333
05:15.24 learner ~20.0 / 0.03
05:15.25 ibot 666.666666666667
05:16.02 learner heh, so I'm paying about a 700% markup for the sake of just a little better quality .. :)
05:21.28 narnia you understand the cdrom so why do the opposing lawyers have such a hard time with it?
05:28.02 learner because it's their job to make you look unreasonable at the expense of potentially looking stupid

12:34.24 learner d_rossberg, it's not just anonymous -- it's everyone having trouble with cvs.
12:34.42 learner took me quite a while to get that last commit in
12:35.02 learner kept giving me the same error as you -- if you just keep retrying, it should eventually update

12:47.24 d_rossberg his works for me too
12:47.38 d_rossberg but try this: https://sourceforge.net/account/login.php
12:48.19 d_rossberg (it's the "Login via SSL" link)
12:48.55 learner it works for me

12:55.54 d_rossberg it was a nice time, 10 years ago
12:57.48 learner you're added now, so you should be able to check out non-anonymously now and get updates in real time
12:58.10 learner cvs -d d_rossberg@cvs.sf.net:/cvsroot/brlcad co -P brlcad
12:58.43 learner you should be able to upload an ssh key to sf.net under your user profile page too, and you won't have to keep entering in a password
13:00.10 learner you also have commit access, if you need to fix something or want to work on something
13:01.45 d_rossberg i'll test the account today; maybe i've to make some changes for the proxy server
13:04.09 d_rossberg but i'll wait with the commits
13:04.21 d_rossberg next week i'm on holiday
13:06.52 learner no problem either way
13:07.11 d_rossberg the kindergarten closes for a week, and my wife's work is more important then mine (at least at the moment)
13:17.35 d_rossberg the protocol for non-anonymously check out is ssh, isn't it?
13:39.18 learner yes
13:39.39 learner ahh, heh, so maybe a problem for you at work..
13:48.14 d_rossberg yes, it's a very secure place here :-}
14:09.04 brlcad you can be very secure and still allow ssh, but it does require more diligence on tracking vulnerability reports
14:16.32 d_rossberg we have a department to do this
14:16.48 d_rossberg i'll ask them, but after my holiday
14:17.16 d_rossberg till then i'll try it from home

17:33.49 clock- Hello
17:38.52 brlcad hello clock-
17:42.44 clock- I have just installed brlcad as I am searching for a CAD for mechanics
17:42.46 clock- for Ronja project
17:42.50 clock- http://ronja.twibright.com
17:43.17 clock- I have just installed it and would like to know if it's possible to get some example 3D file with easy instruction how to display it on screen.
17:43.32 clock- I tried to convert from DXF but the dxf-g converter crashed on seemingly internal error.
17:44.24 brlcad interesting project
17:45.07 clock- The tool has to be free software, because project philosophy requires it (it's User Controlled Technology, analogue of free software in hardware realm)
17:45.19 brlcad sorry, was reading your site.. :)
17:45.37 brlcad yeah, there are example files in the source distribution in the db/ directory
17:46.29 clock- how became brlcad free software? Did it ARL itself or did someone write them and asked for all the sources and documents and published them?
17:46.43 brlcad i'd be interested in getting your dxf to debug the problem
17:46.51 brlcad perhaps you could post it to our bug tracker?
17:46.52 clock- cool :)
17:48.12 clock- Yeah, I got it.
17:48.18 clock- But it's not published yet :(
17:48.29 clock- It says like:
17:48.31 clock- ERROR: INSERT references non-existent block (DICTIONARYVAR)
17:48.31 clock- <PROTECTED>
17:48.31 clock- *** glibc detected *** double free or corruption (!prev): 0x080807a8 ***
17:50.01 brlcad heh, people have asked for brl-cad under the foia and gotten rejected over the years .. the foia doesn't apply to all codes
17:50.11 brlcad ARL supported us going open source
17:50.26 brlcad it just took 5 years of my convincing
17:50.32 clock- freedom of information act?
17:50.37 brlcad yes
17:50.52 clock- Heh, cool work! :)
17:51.36 clock- brl-cad is surprisingly similar to GRASS GIS - wasn't it like this, too, under foia?
17:51.37 brlcad i'm happy :)
17:51.54 clock- I can't wait until I display the cool brlcad logo here:
17:52.09 clock- http://ronja.twibright.com/web.php
17:52.21 brlcad grass is slightly similar.. they took the much easier legal route -- they just dropped it into the public domain
17:52.56 brlcad the user community (schools in europe, iirc) then picked it up and claimed copyright, assigned gpl, etc
17:53.48 brlcad that is a lot of logos :)
17:53.48 clock- Ah, seems like I have reproduced the problem on a publicly available DXF!
17:54.17 brlcad yeah, I've seen that exact error before.. just haven't found a good test case yet for debugging it
17:54.29 brlcad maybe even the same publicly available dxf.. :)
17:55.12 clock- It's http://ronja.twibright.com/drawings/hood.dxf
17:55.24 clock- And the critical command was dxf-g hood.dxf hood.g
17:55.43 clock- Is this report enough or would you like me to enter into bug tracking system?
17:56.13 clock- Anyway, US army and governments seems to be pretty useful - DARPANET alias Internet, GRASS, BRLCAD,...
17:56.56 brlcad I'd prefer the bug tracker just so the other devs know about it too, but I do have the file now if you don't feel like bothering with it
17:56.59 brlcad thanks
17:58.08 brlcad yeah, BRL-CAD is the only open source solid modeler at this point, so I'm hoping we can continue to pick up more interest and get more people involved with the project
17:59.21 clock- I think Ronja could be a usable display case for BRLCAD. I got 91 installations worldwide:
17:59.42 clock- http://ronja.twibright.com/installations.php
18:00.08 clock- As BRLCAD was released just recently (half a year ago?), I expect to be one of the first project to adopt it, if it happens.
18:00.18 clock- Do you think BRLCAD is usable for a project like this?
18:00.39 clock- I actually wanted to emply it about 3 months ago, but didn't have time to investigaste :)
18:02.43 brlcad BRL-CAD's been around/released for about 20 years.. distributed in source code form even (albeit complicated process to get it).. it's been open source since December 21
18:03.03 brlcad what did you have in mind for how BRL-CAD would be usable?
18:03.49 clock- If the bug level is low enough to not present obstacle in work.
18:04.25 clock- The constant mentions about army, test grounds, report forms and ballistic research laboratory are simply cool.
18:05.07 clock- That's like "Ronja is now going to be real star wars. Please send billions of dollars in gifts, we are going to make a reeeeaaaaal good connectivity party ;-) "
18:05.41 brlcad the bug level is very low for most everything that we have to deal with.. like I said, it's a code that's been evolving for a very long time -- very mature code/project
18:05.41 clock- Survivability/Lethality. Even better, in context of (potentially laser) optical datalink ;-)
18:05.55 clock- As old as I am :) 1979, too.
18:06.00 brlcad there is on-going development, though, so some areas will be more/less developed than others
18:06.22 clock- The documentation seems to be written with real care - exceptional...
18:06.41 clock- Oh - lessons about MGED - shit - cool :)
18:06.45 brlcad brl-cad wasn't designed for drafting needs (blueprints), so if that's specifically what you need, there might be better tools
18:07.09 brlcad but for actual modeling, and visualizations, brl-cad will do that quite nicely
18:07.14 clock- DO you mean 2D blueprints with all those dimensions?
18:07.20 clock- I am using QCAD for it.
18:07.47 clock- Wish Linux kernel folks had the same approach to documentation as BRLCAD has...
18:11.55 brlcad sorry, still reading your site.. hold on a sec.. :)
18:14.25 clock- Found a bug in mged intro: Create -> Make solid doesn't exist. Should be Ellipsiond instead of Make solid probably.
18:15.44 brlcad ~change 703 CZK to USD
18:16.01 clock- http://brlcad.org/build_CVS.html deadlinks to http://brlcad.org/index.html ("back to main page")
18:21.10 brlcad questions questions .. :)
18:21.24 brlcad how in the world is the response times on the photoreceptors that fast?
18:21.29 brlcad or are they really just that fast?
18:21.52 clock- The response time of SFH203 photoreceptor is about 5ns.
18:22.14 brlcad is it sending out data already encoded, like different frequencies are different values?
18:22.21 clock- Fiber optics receptors for 10Gbps, 40Gbps etc. speed have it under 1ns.
18:22.52 brlcad that is just incredible
18:22.55 clock- It's using basically the same baseband encoding as ordinary 10Mbps ethernet over twisted pair or coax.
18:23.11 clock- Laser pointer diode can go with modulation rate up to say 1GHz.
18:23.21 clock- This LED can go up to about 10 or 20 MHz.
18:23.27 clock- Infra LED only to 10MHz.
18:24.01 clock- I have entered the bug with hood.dxf
18:24.13 brlcad okay, thanks
18:24.41 brlcad did you make that dxf in qcad?
18:25.07 clock- yes in qcad
18:25.14 brlcad as for the documentation bug, it's known/fixed already.. just not reposted to pdf
18:25.33 brlcad as you found, it's just renamed/moved
18:27.00 clock- I have entered therefore bug #1 and #3.
18:28.46 brlcad heh, there's some other guys at work that are interested now too
18:28.53 brlcad i'll have to show them the site later
18:32.05 brlcad okay, so back to your original questions... what was your questions? :)
18:33.11 brlcad i think it could be of use, model the emitter, visualize each of the components individually in 3d
18:33.18 clock- to load some model and display - but now I am making the radio according to tutorial.
18:33.33 brlcad you could even simulate the transmission properties as a custom raytrace application
18:33.52 brlcad ahh, yes.. you wanted to look at something quick
18:34.03 clock- I want to make a 3D model how to mechanically assembly consoles etc. People get confused by descriptions like "take 3rd bolt from the right and put through rear hole of side adjacent to..."
18:35.03 brlcad http://ftp.brlcad.org/tmp/havoc.g
18:35.16 brlcad save that file, and open it up with mged
18:35.29 brlcad in mged, type: e havoc
18:35.39 clock- May I run two instances of mged simultaneously?
18:35.43 brlcad sure
18:35.47 clock- HTTP request sent, awaiting response... 403 Forbidden
18:35.47 clock- 20:33:08 ERROR 403: Forbidden.
18:35.52 brlcad ah, hold on
18:36.13 brlcad try now
18:37.46 clock- OK - loaded, blue view.
18:37.49 clock- How do I display it?
18:38.30 brlcad e havoc
18:38.44 brlcad or if you're a mouse guy, go to Tools -> Geometry Browser
18:39.12 brlcad and double-click the name "havoc"
18:39.14 clock- Ah, helicopter :)
18:39.26 clock- Is it possible to display with non-wire solid shapes?
18:40.35 brlcad it is, couple ways
18:40.55 brlcad in the command window, type: rt -F/dev/Xl
18:41.54 brlcad or go to File -> Raytrace
18:42.10 brlcad and hit the raytrace button
18:43.50 clock- hmmm... it's slowly raytracing :)
18:43.52 brlcad mged isn't too friendly as a "discovery interface" .. fyi
18:44.09 clock- Is it possible to select some medium detail solid view?
18:44.15 brlcad many call it "expert friendly" as there's lots of commands
18:44.18 clock- yes - the same with GRASS.
18:44.37 clock- is it using povray, or it's internal engine?
18:45.13 brlcad heh, no povray is a dog at raytracing the same models
18:45.48 brlcad BRL-CAD has one of the first raytracers ever written -- the first parallel one
18:46.15 brlcad highly optimized for solid model rendering for analyses
18:46.33 brlcad like signature analyses, multispectral imagery, penetration details, etc
18:47.51 clock- what does mean that povray is dog? Imprecise? Or slow?
18:48.04 brlcad slow and imprecise
18:48.17 brlcad they do have a nice global illumination model, though
18:49.26 brlcad to answer your question, there is an experimental mode that will draw everything shaded/solid
18:49.38 brlcad but it's not recommended at all for something like havoc
18:51.09 clock- I got the output image :) Nice :) Windows look like real glass :)
18:51.44 brlcad and that's the simple defaults
18:51.55 brlcad you can get more realistic by turning on/up some options
18:52.05 clock- So that is it possible to use brlcad like for simulation of glass lens illuminated with point source in infinity and looking at shape and colours of the focus blot?
18:53.15 clock- Is it possible to have wireframe with hidden invisible edges?
18:53.25 brlcad it is, though the computations to simulate that approach that of global illumination for proper caustics
18:53.32 clock- Or at least wireframe with lines clipped and not removed when they don't fit the window?
18:54.10 brlcad Misc -> Z Clipping
18:54.16 brlcad turn that off
18:54.46 brlcad brl-cad's photon mapping will do the caustics fairly cheaply
18:54.51 brlcad i'll see if I can find an example
18:56.20 clock- Or at least wireframe with lines clipped and not removed when they don't fit the window?
18:56.23 brlcad here's some more geometry examples: http://ftp.brlcad.org/db/
18:57.34 clock- I turned off the Z clipping and it still shows hidden edges - however something has changed.
18:58.04 brlcad ahh, i see what you mean now i think
18:58.10 brlcad hiding the back facing lines
18:58.49 brlcad no, there's not really a mode for that -- if you turn on depth queing, it should get better.. stuff in the front is brighter, stuff behind will be darker
18:59.07 brlcad Misc -> Depth Cueing
18:59.20 clock- it's impressive anyway.
18:59.37 brlcad there are "shift grips" that might feel more familiar to you
18:59.51 brlcad like control+mouse drag
19:00.01 brlcad and shift+mouse drag
19:00.18 brlcad and control+shift+mouse drag .. etc
19:01.55 brlcad mged is only 1 of about 400 apps that comprise brl-cad, although mged is one of the largest and few that have a gui

19:06.33 clock- is there a library of steel sections like U, I etc.?
19:09.08 clock- The standard views are cool :)
19:12.11 d_rossberg brlcad: ssh-checkout works from my home
19:12.47 brlcad clock-: not that I can share..
19:13.14 brlcad there is probably a lot of really much more impressive stuff that cannot be shared. ;)
19:15.02 clock- brlcad: are you working in arl/brl?
19:16.00 brlcad clock-: http://db.brlcad.org/tmp/moss.png and http://db.brlcad.org/tmp/moss_edge.png the latter is "rtedge"
19:17.58 brlcad d_rossberg: good to hear
19:19.07 d_rossberg but it's not very fast, only ISDN
19:20.47 brlcad it's not very fast right now regardless with all the cvs work they've been doing
19:20.56 clock- rtedge will be good for technical drawings of assembly, I think.
19:20.58 brlcad adding -z9 to the checkout/update line should speed it up
19:21.06 clock- Is it possible to generate it into vector format, or only raster?
19:21.57 d_rossberg brlcad: this is exactly my setting :-)
19:22.13 brlcad i know rtedge only does raster, it's visualizes geometry edges via raytracing
19:22.36 clock- aha
19:22.52 brlcad I vaguely recall mged having something like that experimental a long time ago, but I "don't think so"
19:24.18 brlcad d_rossberg: heh
19:26.32 clock- Edit -> Scale doesn't exist - where is it?
19:26.42 clock- Used in mged tutorial lesson 9
19:27.25 brlcad the menu changes as you progress up through the steps
19:27.37 brlcad one of the earlier steps would have been to select the geometry for editing
19:28.16 brlcad there's a solid/primitive edit mode and a matrix edit mode depending on what you're editing and how
19:48.50 clock- hm, done a ball in glass box :)
19:49.06 brlcad hehe
19:51.22 brlcad it takes patience at first, but then one can really get efficient with it once you know the core commands/menus/etc
19:51.35 brlcad the expert modelers are pretty darn impressive at their speed
19:53.24 clock- is it possible to make constraints?
19:53.42 clock- Like two boxes sharing facet, two cylinders sharing an axe
19:53.51 clock- or putting something into intersection of something else?
19:53.57 clock- axe -> axis
19:56.08 d_rossberg brlcad: I'm done: 50 min
19:56.44 clock- brlcad: thanks, have to go, have a nice time, goodbye
20:35.10 brlcad heh
20:55.10 CIA-3 BRL-CAD: 03brlcad * 10brlcad/misc/pro-engineer/Makefile.am: typo in the am var for echo
21:21.44 CIA-3 BRL-CAD: 03brlcad * 10brlcad/misc/pro-engineer/mk.in: cannot use a brl-cad header without either installing first or defining HAVE_CONFIG_H, so do the latter
