| 00:22.18 | Maloeran | Please cvs commit when done hax0ring the c0dez, Erik :) |
| 00:43.52 | deltazap | alright, i think it's about time that i came out of idling and introduced myself you you all :P |
| 00:45.11 | brlcad | howdy deltazap |
| 00:45.23 | brlcad | feel free to lurk as long as you like ;) |
| 00:45.26 | deltazap | hah |
| 00:45.54 | brlcad | kudos on the name ;) |
| 00:46.06 | brlcad | even if you do spell it wrong :D |
| 00:46.13 | deltazap | my normal name was taken |
| 00:46.57 | deltazap | :O |
| 00:47.05 | deltazap | it's phonetically correct :P |
| 00:47.12 | *** join/#brlcad digitalfredy (n=digitalf@200.71.62.161) |
| 00:47.13 | brlcad | heh |
| 00:47.49 | deltazap | i'm an MechE at the University of South Florida |
| 00:48.06 | brlcad | ahh, fun |
| 00:48.13 | brlcad | party school, eh? :) |
| 00:48.25 | deltazap | i started working with a robotics group about 2 weeks ago and, surprise!, they don't have anything for cad software |
| 00:48.34 | deltazap | more like farm school :P |
| 00:48.44 | brlcad | ahh |
| 00:48.54 | deltazap | you must have us confused with FSU or UF |
| 00:48.57 | brlcad | i just associate all things florida with a party |
| 00:49.02 | deltazap | haha |
| 00:49.42 | brlcad | probably because i'm usually in miami or panama city or eglin .. good stuff |
| 00:50.14 | deltazap | i'm originally from the melbourne area, just south of Cape Canaveral |
| 00:50.51 | deltazap | the panhandle isn't as nice as central florida from what i hear |
| 00:51.30 | brlcad | yeah, it's not |
| 00:52.15 | deltazap | so, i was on a quest for (useable) cad software for the mac when i came across brl cad |
| 00:52.51 | brlcad | well you should be forewarned that depending on your (pre)conceptions of CAD, this may or may not be what you're looking for |
| 00:53.32 | deltazap | yeah, i've inched into it a bit, backed off, looked at it a bit more |
| 00:53.40 | brlcad | we're by far the best/only open source solid modeling CAD software in production use, decades of development invested, but we don't do it all by a long shot |
| 00:54.14 | brlcad | we're specifically short on capable developers if you know of any ;) |
| 00:54.15 | deltazap | it's interesting how brl cad approaches the problem |
| 00:54.56 | brlcad | I presume you've read the Overview and the Industry Diagram, perhaps the Intro to MGED as well? |
| 00:55.14 | deltazap | heh, don't get to stick my head outside of our engineering labs long enough to talk to many people |
| 00:55.17 | deltazap | yeah, i have |
| 00:57.22 | brlcad | the industry diagram in particular should give a sense for how we currently fit into the big picture -- e.g. AutoCAD is CADD software and our overlap with them is rather limited, similarly BRL-CAD has limited CAM facilities other than basic modeling, representation, and conversion support |
| 00:58.34 | brlcad | but if solid modeling is your need, performing analyses, computing metrics like weight and volumes, or programmatic purposes, geometry engine representations, data manipulations, CSG implicity geometry .. then you're golden ;) |
| 00:59.03 | brlcad | what are you looking to do? |
| 01:01.11 | deltazap | right now, just modeling so that i can show people my designs |
| 01:01.47 | deltazap | something just to record designs since the lab has nothing at all |
| 01:01.56 | brlcad | got it |
| 01:02.08 | brlcad | for that, the mged tutorials are going to be essential |
| 01:02.45 | brlcad | mged has a lot of good aspects like a powerful command line, but user-friendly it is not, nor is it a discoverable interface |
| 01:03.35 | brlcad | a known limitation that is being worked on, but a limitation regardless that requires lots of experience and expert knowledge to utilize effectively |
| 01:04.28 | brlcad | once you do master it, our best modelers can generally be just as proficient at most tasks as they are in other CAD systems, even faster at doing some things, but it takes a while to get to that point |
| 01:05.59 | brlcad | but once you do, things like http://ftp.brlcad.org/tmp/primitives/Plate%20IV.png do become possible |
| 01:07.07 | deltazap | holy smokes! |
| 01:13.01 | deltazap | i'm used to command line interfaces |
| 01:13.33 | deltazap | unlike most mech e's, i have quite a bit of computer experience :P |
| 01:14.58 | Maloeran | Very nice brlcad, how come I don't have access to these models ;) |
| 01:15.13 | brlcad | Maloeran: :) |
| 01:15.40 | brlcad | Maloeran: you have access to some of those, and some considerably better |
| 01:16.53 | Maloeran | I do? The only real engineering model I have around is truck_bots, though I didn't look very far |
| 01:17.06 | brlcad | you just don't know who to ask, or what exactly to ask for .. |
| 01:17.24 | brlcad | none of the best models are public releasable |
| 01:17.44 | brlcad | even that model isn't, but a picture of it is ;) |
| 01:19.33 | ``Erik | mal: I commited as I was doing it. that's the way to do it |
| 01:20.39 | ``Erik | *look* oh yeah, the model brlcad pasted ain't public release, that the image is public release has caused issues recently |
| 01:21.23 | ``Erik | mal: I fixed the log2 check issue and made the rays per second a little more readable... |
| 01:21.24 | Maloeran | Yes, one could perhaps guess where the fuel tanks are, and the ammo |
| 01:21.45 | Maloeran | I didn't receive email notification about these changes, strange |
| 01:22.05 | ``Erik | heh, one could look at public release photographs of the vehicle and figure that out... but some people are stupid |
| 01:22.57 | ``Erik | I got loads of python errors when I commited |
| 01:23.07 | ``Erik | which I assume is the mail agent |
| 01:23.15 | Maloeran | cool. |
| 01:23.53 | ``Erik | and I ran around showing the current rfdemo to anyone who might give half a flying fuck heheheh :D |
| 01:23.59 | ``Erik | that thing is just smokin', dude |
| 01:24.18 | Maloeran | Thanks :) |
| 01:24.41 | ``Erik | on the quad opteron running fbsd, a steady 30fps at 1024x768 |
| 01:25.02 | ``Erik | on the octo-opteron running linux, it bounced between 25 and 40 fps erratically, mostly staying around 35fps |
| 01:25.27 | Maloeran | With or without transparency? |
| 01:25.48 | Maloeran | I never remember what I leave as default for rfdemo when I commit, toggling a lot |
| 01:25.51 | ``Erik | without |
| 01:26.04 | ``Erik | 10fps on the 12 core itanium running linux |
| 01:26.05 | Maloeran | Ah. It's 80fps in 1024x78 on my 8 cores |
| 01:26.11 | ``Erik | 5fps on a dual core g5 running osX.4 |
| 01:26.31 | brlcad | ``Erik: fortunately, even that particular image is getting published in a book, and was recently re-approved for release via my jmum presentation |
| 01:26.31 | Maloeran | Ah well, no SSE there |
| 01:26.34 | ``Erik | <-- probably experiencing network issues, was running it remote X over 100baseT |
| 01:27.10 | brlcad | along with a slew of other nifty pictures... |
| 01:27.10 | Maloeran | Is Lee pleased enough, overall? |
| 01:27.17 | ``Erik | heh, brlcad, sab bc refused to sign off on a pub with that pic... once the pic was removed, she signed... |
| 01:27.34 | brlcad | Maloeran: he was yelling your name along with various profanities.. dunno... |
| 01:27.58 | ``Erik | hehehe |
| 01:28.33 | ``Erik | when I stopped by his office at 5pm and told him to log into that machine and run it, once he got over the foibles of remote X and his fucked up workstation, he was extremely happy, it made his day |
| 01:29.29 | ``Erik | of course, his day wasn't exactly a shining beacon of awesomeness, I mean, chock full of meetings involving nontechnical people maching technical decisions that impact him, heh |
| 01:29.41 | ``Erik | which is par for the course these days :/ |
| 01:30.20 | Maloeran | :/ It still makes my day as well to hear that some people far away appreciate the software |
| 01:30.34 | ``Erik | tell ya what |
| 01:30.46 | ``Erik | it impressed me enough to run around and show lee and brlcad... |
| 01:30.46 | Maloeran | http://www.rayforce.net/demo01-ms.avi - Transparency walkthrough of the terribly heavy galleon model, 60mb, if anyone is interested |
| 01:30.48 | ``Erik | :) |
| 01:30.53 | Maloeran | :D |
| 01:31.08 | ``Erik | and brlcad was getting 40fps from the quad opteron, opposed to my 30 |
| 01:31.13 | ``Erik | better networking, I guess :/ |
| 01:31.28 | Maloeran | Or http://www.rayforce.net/demo00-ms.avi for flat shading demo, if you want to have a look |
| 01:32.28 | deltazap | well, thanks guys :) |
| 01:32.38 | deltazap | i'm sure i'll have many more questions in the future |
| 01:33.03 | brlcad | Maloeran: can't you encode an mpeg2 or mpeg4 somewhere? :) |
| 01:33.25 | brlcad | and dear ghod.. that's a damn big video file :) |
| 01:33.58 | ``Erik | those're mpeg-4, brlcad |
| 01:34.06 | ``Erik | he just named 'em... "funny" |
| 01:34.22 | ``Erik | (avi is the uncompressed layout, mpeg4 is the compression algo... vid compression is weird like that) |
| 01:34.36 | ``Erik | be like if he named an mp3 blah.pcm |
| 01:34.41 | Maloeran | Yes, it's all msmpeg4-v2 so it even runs on windows out of the box |
| 01:35.07 | Maloeran | Sorry about the huge files, any loss of quality is really visible, so this is almost loseless |
| 01:35.25 | Maloeran | ( I have loseless versions too if you prefer :) ) |
| 01:35.32 | ``Erik | 2.4 gigs a pop? D: |
| 01:35.33 | ``Erik | :D |
| 01:37.07 | Maloeran | Eheh, I still have that, but also x264 loseless compressed videos ; but I don't know how that runs on most players |
| 01:37.24 | deltazap | so, are most pepole in here developers for brl cad? |
| 01:37.25 | ``Erik | <-- uses vlc, it does everything |
| 01:37.32 | ``Erik | only a couple of us, delta |
| 01:38.02 | deltazap | ``Erik: and everyone else is an enthusiast? ;) |
| 01:38.20 | louipc | hobbist |
| 01:39.14 | ``Erik | brlcad and myself are brl-cad developers, maloeran is developing a piece that will be integrated into BRL-CAD in about a month |
| 01:39.17 | ``Erik | *look* others are former devs, enthusiests, interested parties, etc |
| 01:39.23 | ``Erik | and bots, can't forget the bots :) |
| 01:39.36 | deltazap | of course not :) |
| 01:39.50 | louipc | oh so that's who's publishing this channel eh |
| 01:39.51 | deltazap | they're a staple of any irc room |
| 01:40.01 | ``Erik | channel, not room |
| 01:40.04 | ``Erik | quit talking like an aoler |
| 01:40.05 | ``Erik | :D |
| 01:40.08 | deltazap | hah |
| 01:40.13 | louipc | omg lol |
| 01:40.24 | deltazap | hai2u |
| 01:40.29 | ``Erik | A/S/L!!!!~??! |
| 01:40.40 | Maloeran | lololol!!1 |
| 01:41.15 | deltazap | brlcad mentioned being able to do analysis with models that you build with brl cad, what sort of analysis is (publically) available? |
| 01:41.15 | ``Erik | (heh, hai2u as in goatse/lemonparty/tubgirl grade shock image site?) |
| 01:41.57 | deltazap | ``Erik: not as much, just aoler mentality |
| 01:42.02 | ``Erik | volume/weight analysis, exposed area, ... |
| 01:42.25 | ``Erik | a disturbing amount is "publically available", but saying the extent is not :/ |
| 01:42.41 | deltazap | heh |
| 01:42.43 | louipc | ballistics |
| 01:42.46 | louipc | non? |
| 01:42.59 | brlcad | ``Erik: er, I meant an mpeg4 not using the divx encoding |
| 01:43.02 | ``Erik | <-- been kinda interested in doing things like optic analysis and mechanical stress/strain analysis as public type activities |
| 01:43.23 | deltazap | mechanical stress/strain analysis would be awesome |
| 01:43.45 | louipc | that would be neat |
| 01:43.45 | deltazap | that would be the one that i'm most interested in since that's related to my field |
| 01:43.48 | ``Erik | BRL-CAD's primary funding comes from ballistic type analysis, yes, but that actual work is done in another program... brlcad just provides the geometry information |
| 01:44.04 | louipc | deltazap: you're doing robots? that's awesome |
| 01:44.05 | deltazap | had to work with ansys today for one of my classes |
| 01:44.08 | louipc | ah ok |
| 01:44.16 | deltazap | what a pain |
| 01:44.24 | brlcad | deltazap: the other devs drop in from time to time, or live on the mailing lists |
| 01:44.31 | deltazap | interesting |
| 01:44.32 | brlcad | or just commit and cause problems when they can ;) |
| 01:44.37 | ``Erik | heh |
| 01:44.38 | louipc | hah |
| 01:44.43 | deltazap | louipc: yes :) unmanned systems |
| 01:44.45 | ``Erik | you mean bob? :D *duck* |
| 01:44.48 | deltazap | haha |
| 01:45.00 | brlcad | i think bob tried to join the channel twice |
| 01:45.10 | brlcad | never got it to work |
| 01:45.27 | ``Erik | I mean the causing problems part... ain't his fault, though, he was working the windows port and not focused on portability |
| 01:45.28 | deltazap | our group is actually sponsored by ARL for some of our projects |
| 01:45.31 | Maloeran | Bob from Survice? |
| 01:45.38 | louipc | deltazap: well as I see it, that's what a robot is. It bugs me when they call those RC doodads robots like on Robot Wars |
| 01:45.40 | brlcad | is there any other bob? :) |
| 01:45.42 | ``Erik | mal: ja, the dude we had lunch with at the golf course |
| 01:45.50 | brlcad | bob's pretty cool guy, *real* easy going |
| 01:46.03 | deltazap | louipc: http://www.cse.usf.edu/USL/uslindex.htm is our group's site |
| 01:46.09 | ``Erik | he used to be arl civvy, same office as john |
| 01:46.25 | brlcad | very much a least-resistance path coder though, whatever gets the job done fastest no matter how maintainable, clean, fastest running it is |
| 01:46.29 | Maloeran | I'm surprised Bob couldn't manage to come on IRC |
| 01:46.47 | brlcad | he just didn't try really hard.. and might have had firewall issues |
| 01:46.48 | Maloeran | Yes, I saw some of his Fastgen code, it isn't that bad |
| 01:47.20 | brlcad | Maloeran: heh, he wrote most of the gui code in mged .. still think that? :) |
| 01:47.30 | Maloeran | Ouch! :) |
| 01:47.32 | brlcad | that said, he also wrote archer which is worlds cleaner/improved ;) |
| 01:47.53 | brlcad | he was using tcl before it was really stabilized |
| 01:48.17 | brlcad | plus he's colorblind (so lets make him a gui coder! woot) |
| 01:48.17 | Maloeran | I think I just have a high esteem for Bob as Mark told me he also first submitted progress reports and invoices as a .txt file, as I initially did |
| 01:48.43 | brlcad | he's a very simple down to earth guy |
| 01:49.05 | brlcad | really easy going, makes awesome guitars |
| 01:49.06 | ``Erik | bob's colorblind, too? |
| 01:49.16 | louipc | deltazap: nice, I'd really like to do stuff like that |
| 01:49.18 | brlcad | yeah, ironic, no? |
| 01:49.37 | louipc | solid body guitars? |
| 01:49.41 | ``Erik | akoostics |
| 01:49.48 | deltazap | louipc: this job was just kinda dropped into my lap |
| 01:49.52 | brlcad | i almost bought one off him before he left, but then I was burning cash on other toys at the time |

| 01:50.36 | louipc | neato |
| 01:50.39 | deltazap | louipc: problem is that is a bunch of CS PhD students and noone wanted to work with the hardware when it broke. makes it hard to show off their systems :P |
| 01:50.46 | brlcad | you so wouldn't think he makes classic guitars, with his military background, potty mouth, and laid back coder attitude |
| 01:50.59 | Maloeran | He's apparently much into fishing too |
| 01:51.02 | deltazap | *its |
| 01:51.09 | louipc | deltazap: yeah definitely. software isn't everything :/ |
| 01:51.29 | brlcad | it isn't?? |
| 01:51.35 | deltazap | hah |
| 01:51.42 | brlcad | Maloeran: and guns |
| 01:51.51 | brlcad | shooting with him is fun, if you get the chance |
| 01:51.56 | deltazap | that and they don't have anyone to design and build custom hardware |
| 01:51.57 | brlcad | pretty experienced |
| 01:52.07 | brlcad | assuming you're not gunphobic or something |
| 01:52.12 | Maloeran | I think I'll pass that :), not my kind of activity |
| 01:52.35 | Maloeran | I think I'm not very fond of these particular... tools, never saw a gun though |
| 01:52.51 | Maloeran | ( They are fairly rare in Canada ) |
| 01:52.54 | brlcad | if you hung around him long enough, you probably would be enticed.. it's hard not to be ;) |
| 01:52.56 | louipc | yea |
| 01:53.34 | brlcad | not hunting, target practice shooting clay pigeons .. though bob hunts too iirc |
| 01:53.51 | louipc | I went to a flea market in georgia and I was pretty freaked out by all the weapons |
| 01:54.07 | Maloeran | I'll settle for bicycle rides with Lee instead ;) |
| 01:54.20 | brlcad | Maloeran: i'm not sure it's a "rare in Canada" as it is a "rare in and around cities" |
| 01:54.44 | brlcad | it's not like I could easily go shooting down in baltimore (at least outdoors), without getting shot at |
| 01:54.50 | ``Erik | heh, reading on laws and stuff, it's actually easier to buy a gun in canada than in the US |
| 01:55.11 | ``Erik | less wait period, less background check... but they're all hunting grade weapons, not "self defense" weapons |
| 01:55.18 | louipc | should be even easier soon too |
| 01:56.11 | brlcad | yeah, i'm referring more to the shotgun and rifle sort, not a handgun or uzi .. though those can be fun too I hear :) |
| 01:56.35 | ``Erik | of course, the biggest news item gun crimes in the us are with hunting rifles... the wv sniper, etc |
| 01:57.42 | brlcad | deltazap: hmm.. I notice that ARL is one of your groups funding sponsors.. |
| 01:57.52 | deltazap | yes :) |
| 01:58.06 | brlcad | that's probably a great lead towards securing a job ;) |
| 01:58.25 | brlcad | do you know what part of ARL? |
| 01:58.50 | brlcad | that sounds like the sort of stuff Twingy is working on now |
| 01:59.10 | deltazap | hang on, i have a card from one of the guys that came a week ago to look at everything |
| 01:59.35 | deltazap | weapons technology analysis branch |
| 02:00.58 | deltazap | when he came, i basically got a job offer. i've only been with the group for three weeks :P |
| 02:02.38 | brlcad | yeah, there are positions open all over the lab, a hard need for bodies and talent |
| 02:03.17 | Maloeran | They aren't too fond of canadians apparently, though |
| 02:04.33 | louipc | :P |
| 02:04.33 | brlcad | hmm.. that branch is probably part of WTD |
| 02:04.34 | ``Erik | does it have an office symbol? |
| 02:04.34 | brlcad | pearson and company |
| 02:04.34 | ``Erik | like AMSRD-ARL-WM-WB ? |
| 02:04.42 | deltazap | ``Erik: amsrd-arl-wm-bf |
| 02:04.47 | brlcad | eep |
| 02:04.50 | ``Erik | hah, it IS wm, bitch! |
| 02:04.53 | brlcad | heh |
| 02:05.17 | ``Erik | <-- in AMSRD-ARL-SL-BS |
| 02:05.24 | ``Erik | yes, you read that right. BS. |
| 02:05.26 | ``Erik | :( |
| 02:05.37 | brlcad | better that BF |
| 02:05.43 | ``Erik | best friends? |
| 02:05.43 | ``Erik | :D |
| 02:05.45 | brlcad | s/that/than/ |
| 02:05.51 | deltazap | lol |
| 02:05.58 | ``Erik | that's what you meant, right, you pillowbiter? |
| 02:06.03 | ``Erik | O:-) |
| 02:06.08 | brlcad | uh huh |
| 02:06.30 | louipc | ! |
| 02:06.51 | brlcad | oh yeah.. and libapr somehow got updated again |
| 02:07.07 | brlcad | but I was able to trace down the crashes to mod_security and mod_rewrite |
| 02:07.09 | ``Erik | this is the part of the day where you eat some food, have a nice relaxing adult beverage and prepare to watch southpark, buddy |
| 02:07.14 | brlcad | so I'm upgrading everything now |
| 02:07.24 | ``Erik | onyour machine in belize? |
| 02:07.28 | brlcad | yeah |
| 02:08.16 | ``Erik | unfortunate that we don't have friendly boots on the ground in that region. |
| 02:08.24 | deltazap | i'm not sure what most of the acronyms mean :P |
| 02:08.27 | louipc | hah I've never heard the term 'adult beverage' before |
| 02:08.43 | brlcad | my schedule is almost exactly 6 hours off right now, 9pm feels like 3pm, which means break time .. and a second burst of energy in about two hours until about 5am |
| 02:09.29 | Maloeran | Sounds great brlcad, I thought one had to be a consultant working remotely to do that |
| 02:09.31 | ``Erik | got insane amounts of stuff done in that period of my life, too |
| 02:09.33 | brlcad | i've tried syncing back 6 hours three times now, but can't hold it for more than a day |
| 02:09.56 | brlcad | Maloeran: seniority ;) |
| 02:10.28 | ``Erik | heh, d'no if it's seniority as much as contractor insulation combined with a perception of being irreplacable :) |
| 02:10.47 | brlcad | but it's good stuff (most of the time), great toys, great code and potential for ideas if you know how to work it |
| 02:11.00 | Maloeran | Eheh. From what I see, brlcad is indeed irreplacable, no one knows the software nearly as well |
| 02:11.28 | ``Erik | I d'no, there may be a couple that do, but they're married to other projects O.o |
| 02:11.31 | ``Erik | :D |
| 02:11.39 | ``Erik | (don't inflate the boys ego, mal) |

| 02:22.22 | Maloeran | Ah no, I didn't |
| 02:22.24 | deltazap | how hard is it to set up the rendering system for multiple machines? |
| 02:22.40 | ``Erik | the automake usage there is much different than BRL-CAD |
| 02:23.07 | ``Erik | given how you lay out the directories and locations of the files, you might like how I did rtcmp a lot more than how rayfarce currently is |
| 02:23.28 | brlcad | how was that? non-recursive? |
| 02:23.40 | ``Erik | <PROTECTED> |
| 02:23.43 | ``Erik | yeah, toplevel build |
| 02:23.53 | ``Erik | reduced presense |
| 02:24.19 | ``Erik | minimalistic, even :) while retaining solid portability |
| 02:24.32 | ``Erik | (though most of it is by leveraging BRL-CAD's portability...) |
| 02:25.10 | brlcad | i'm curious how fast the compile would be without recursive on brl-cad, but hell if I am interested in 1) breaking something that works, 2) editing 535 files, and 3) giving the gnu folks satisfaction on their rediculous ranting |
| 02:25.13 | ``Erik | bear in mind, the code is crude as it's early dev |
| 02:25.59 | ``Erik | I have 3 subdirs total, with the subdirs being linked into the toplevel binary... it was a no-brainer to go with non-recursive |
| 02:26.26 | ``Erik | now PARTS of BRL-CAD might benefit from non-recursive... but most of it is best recursive |
| 02:26.39 | ``Erik | like ADRT might benefit, since it often has 2 or 3 .c files in a subdir |
| 02:27.13 | ``Erik | and the data dirs might |
| 02:28.39 | brlcad | you can still have the makefiles deep with recursive |

| 02:43.02 | Maloeran | Right, okay |
| 02:43.18 | ``Erik | I put #ifdef __linux__ around RF_I386_STACK_ALIGNMENT_HACK |
| 02:44.08 | Maloeran | The problem is glibc specific. Isn't glibc used on other platforms too? |
| 02:44.15 | ``Erik | not to my knowledge |
| 02:44.48 | ``Erik | none of the BSD family and no UNIX uses glibc |
| 02:44.55 | ``Erik | um, HURD/HIRD might |
| 02:44.56 | ``Erik | but, uh |
| 02:44.58 | ``Erik | no one uses that |
| 02:44.59 | ``Erik | :D |
| 02:45.40 | Maloeran | I think you can run some patched glibc on various BSD |
| 02:45.57 | ``Erik | well, yeah, there're ports to install a tweaked glibc |
| 02:46.00 | ``Erik | but its' not natural |
| 02:46.23 | ``Erik | <-- needs to install dragonfly and netbsd to get total coverage :/ |
| 02:46.58 | Maloeran | I probably broke again whatever platforms doesn't have stdint.h, but that's a standard C99 header, and I require C99 to compile |
| 02:48.03 | ``Erik | stdint showed up in the bsd family a long time ago |
| 02:48.39 | Maloeran | You once added some switch to check for the existence of stdint.h, so I assume it wasn't present on some of your test platforms |
| 02:48.47 | ``Erik | ands ince you're c99, you exclude pretty much all the real UNIX platforms |
| 02:49.53 | ``Erik | heh, too bad I don't have aix and hpux boxen |
| 02:51.04 | Maloeran | The SOW said the code is to be written in C99, I'm not too concerned if some archaic Unix platforms still live in 1989. Is it really of any importance to you guys? |
| 02:51.30 | ``Erik | so when're you cutting that mega-box up for different platforms, mal? |
| 02:51.31 | ``Erik | um |
| 02:51.48 | ``Erik | unfortunately, most of our "primary use" machines ARE that archaic. |
| 02:51.59 | Maloeran | Ouch, I see |

| 02:54.44 | ``Erik | performance wise, though, a broad install base may be a big eye opener |
| 02:54.47 | Maloeran | I don't see how you can give more importance to BSD than Linux for some real software |
| 02:55.30 | ``Erik | hm, linux is a limelight baby, bsd is a workhorse in teh shadows |
| 02:55.35 | Maloeran | I know you are personally more fond of BSD, but I don't think that reflects what should be the real priorities... |

| 02:57.06 | ``Erik | fbsd is so mature and just THERE, I have it all done in 2 hours |
| 02:57.16 | ``Erik | and I'm not totally linux stupid, last I checked :) |
| 02:57.47 | Maloeran | :) Surprising... |
| 02:57.54 | ``Erik | from talking to both fbsd and linux people, linux is a bunch of 'kids' who are very vocal... lots of /. stuff |
| 02:58.07 | ``Erik | fbsd users tend to be old professional types who "mkae it work" without fuss |

| 02:59.06 | justin__ | ftp.cdrom.com/pub/asm/party/95 |
| 02:59.20 | Maloeran | Which I think would be an important point to care about Linux a bit |
| 02:59.25 | ``Erik | no, most MSRC clusters are not linux, a couple BIGGIES are linux |
| 02:59.49 | ``Erik | I think aix is better represented |
| 03:00.25 | ``Erik | but bear in mind, MSRC is not about ultimate performance or maintainability, there's a lot of beaurocracy.... a lot of weight is put towards sanctioned finger pointing |

| 03:01.12 | ``Erik | they aint' runnin' gentoo, dude |
| 03:02.19 | Maloeran | Eh well, all right then. I'll be one of these vocal Linux kids :) |

| 03:05.59 | Maloeran | Tsk :), there's so little potential and theorical gain from learning fbsd, and I'll need years to be on par with my Linux |
| 03:16.07 | Twingy | you would think that with glDisable (GL_DEPTH_TEST); that each successive call to drawing an object would draw on top of anything previously existing |
| 03:16.41 | ``Erik | *blink* one would think |
| 03:17.26 | Twingy | given I am seeing random behavior in fbsd and winderz (both are different) I don't know what to believe |

| 05:13.30 | brlcad | ``Erik: since I actually looked at gdb instead of just doing the fix, there are multiple crash points or at least places where mod_security, mod_rewrite, and libphp could independently (i.e. with the other two disabled) crash httpd due to various issues |
| 05:13.57 | brlcad | one crashed inside a log attempt, another while lookup up httpd's running username, another while talking back through apr |
| 05:15.53 | brlcad | the fix is pretty simple, have to get php and apache to both (forcibly) have -pthread added to the CFLAGS -- for php this amounts to building, cd into work, reconfigure with CFLAGS=-pthread, cd out, and reinstall .. for apache2, it's a matter of editing the ports Makefile and appending -pthread to the CFLAGS |

| 14:24.26 | Maloeran | Darn, the functions required are declared static, no symbols |

| 14:31.58 | Maloeran | The video recording performs N buffering so it scales well with threads and distributed processing, but the SDL visualization clearly doesn't ( block and wait every frame ) |
| 14:32.18 | ``Erik | other projects... :) ISST is interactive, CCI is more of a very specialized large scale global illumination concept (not started yet) |
