| kanzure | hi Anvilgames | 09:10 |
| Anvilgames | Hi. | 09:10 |
| Anvilgames | How are you? | 09:10 |
| kanzure | i'm not sure i haven't checked | 09:11 |
| Anvilgames | You're not one for social protocol, then? | 09:11 |
| Anvilgames | Fair enough. | 09:11 |
| kanzure | uh when it suits me i guess | 09:12 |
| kanzure | what's up? | 09:12 |
| Anvilgames | Nothing much. | 09:12 |
| kanzure | what brings you these ways? | 09:12 |
| Anvilgames | I just finished binging on Dresden Codak and wanted more transhumanism in my day. | 09:12 |
| Anvilgames | and the guys in #agi were kind enough to point me to this channel | 09:13 |
| kanzure | what type of transhumanism? the fake kind or the real kind | 09:14 |
| -!- CrazyThinker [~CrazyThin@unaffiliated/lordphoton] has joined ##hplusroadmap | 09:14 | |
| kanzure | hello lord photon | 09:15 |
| Anvilgames | You've lost me completely. | 09:15 |
| Anvilgames | Either one would do, most likely. | 09:15 |
| kanzure | yeah i don't know what to tell you except check the /topic | 09:16 |
| -!- CrazyThinker [~CrazyThin@unaffiliated/lordphoton] has left ##hplusroadmap [] | 09:16 | |
| Anvilgames | which link would you recommend? | 09:16 |
| kanzure | are you familiar with diybio? | 09:17 |
| Anvilgames | Not at all. | 09:17 |
| kanzure | i guess you could look at http://openwetware.org/wiki/DIYbio/FAQ/News | 09:17 |
| Anvilgames | sounds interesting | 09:18 |
| Anvilgames | I've heard of biohacking before, never made the connection to transhumanism. | 09:19 |
| kanzure | how sad | 09:19 |
| Anvilgames | I know. I live a depraved life :) | 09:19 |
| kanzure | no it's transhumanism that is sad | 09:19 |
| Anvilgames | ?? | 09:19 |
| kanzure | are you the ray-kurzweil-sit-around-watching-the-stock-market type? | 09:20 |
| Anvilgames | Okay, as the newbie here I will shut up and let you explain. | 09:20 |
| Anvilgames | No. | 09:20 |
| Anvilgames | I don't have any stock options. | 09:20 |
| kanzure | sit-around-watching-agi-stuff? | 09:20 |
| kanzure | that last one probably isn't as eloquent as it could be | 09:20 |
| Anvilgames | I'm the sit-around-reading-science-fiction-and-wishing-it-were-real type | 09:21 |
| kanzure | what do you do, btw? | 09:21 |
| Anvilgames | Currently I'm a maths student | 09:21 |
| kanzure | grad student? | 09:22 |
| Anvilgames | no, and I don't think I will be | 09:22 |
| Anvilgames | so, what's this channel about? | 09:23 |
| Anvilgames | that should really have been my first question | 09:23 |
| Anvilgames | hello? | 09:25 |
| kanzure | biohacking, transhumanism, open source hardware, other stuff | 09:25 |
| Anvilgames | Sounds good. | 09:25 |
| Anvilgames | What did you mean by "fake transhumanism"? | 09:25 |
| kanzure | social media | 09:26 |
| Anvilgames | What about them? | 09:26 |
| kanzure | you are very hard to talk with | 09:26 |
| Anvilgames | I'll take that as a compliment. | 09:27 |
| archels | kanzure: Have you ever chatted with tav? | 09:27 |
| kanzure | archels: a handful of times | 09:27 |
| archels | He might disagree on that last statement. ;) | 09:27 |
| kanzure | he claims i haven't? | 09:27 |
| kanzure | well that's disappointing | 09:27 |
| kanzure | http://diyhpl.us/cgit/meetlog/plain/meetlog.txt <-- evidence | 09:28 |
| archels | no? | 09:28 |
| kanzure | oh i guess he's not listed there | 09:28 |
| * Anvilgames examines Exhibit A | 09:28 | |
| kanzure | well, he's been listed since then | 09:28 |
| kanzure | sometimes i forget to add in conversations :x | 09:28 |
| archels | He might disagree about the merit of social networking. | 09:28 |
| kanzure | oh, i don't care | 09:28 |
| kanzure | there are merits but i don't think you can pretend that ray kurzweil is actually working on transhuman tech | 09:29 |
| kanzure | or that hplusmagazine is building things behind all of the blog spam | 09:29 |
| archels | Agreed, but getting the word out probably means more research dollars for you and me. | 09:29 |
| kanzure | networking and 'social media' are different concepts (though closely related yes..) | 09:29 |
| kanzure | not really.. hplusmagazine has only been able to bring in money because it scammed someone to pay $15k for 200 clicks/year | 09:30 |
| archels | heh, I wasn't necessarily talking about ad revenue. That's peanuts. | 09:31 |
| archels | Having some converts in the NSF would be good though. | 09:32 |
| archels | (wishful thinkin, I know) | 09:32 |
| kanzure | waiting for grant money isn't that great of a strategy | 09:32 |
| archels | Well, if you have an actual marketable product, then it's a completely different playing field of course. | 09:38 |
| archels | But I think the both of us are doing relatively fundamental research, so that's a no go. | 09:38 |
| kanzure | what fundamental research am i doing? | 09:59 |
| Anvilgames | Actually, what do you do kanzure? | 10:02 |
| kanzure | lots of programming | 10:08 |

| lumos | hi, what is wrong with ram based neural networks | 12:17 |
| lumos | and cnn''s | 12:17 |
| archels | hello | 12:19 |
| archels | What do you mean by RAM based neural networks? | 12:19 |
| lumos | ar ch | 12:32 |
| lumos | archels, | 12:33 |
| lumos | i will explain | 12:33 |
| mjr | instead of, say, gnu or lamb based neural networks | 12:33 |
| lumos | you could have | 12:33 |
| lumos | an 8 by 8 grid of cells | 12:34 |
| lumos | on or off | 12:34 |
| lumos | and generate each possible arrangement you would get 2^64 patterns | 12:34 |
| lumos | say we were doing a handwriting recognition system | 12:34 |
| lumos | and thnnnnnnnnnnn | 12:34 |
| lumos | program for each kind of pattern what number it is or if it is no number | 12:34 |
| lumos | but thats just unfeasabe coz u would need kuje 170 million 1gb rams i calculated | 12:35 |
| lumos | so an alternative is tooooo | 12:35 |
| lumos | take the 8 by 8 grid and split it into 4 | 12:35 |
| lumos | generate for each of these smaller grids every possible arrangement | 12:36 |
| lumos | thats 2^4 manageable | 12:36 |
| lumos | 4 * 2^4 | 12:36 |
| lumos | and then dont forget you must do this 10 times for each of the numbers | 12:36 |
| lumos | for each of the squares now assign it a 1 or 0 it is either tht number or it isnt | 12:37 |
| lumos | then you have a summing junction | 12:37 |
| lumos | which sums the 1s and 0's and gives you a say this is 25% a 6 | 12:37 |
| lumos | archels, do you understand | 12:38 |
| lumos | archels, do you know what a cnn is | 12:39 |
| lumos | mjr, what is a gnu or lamb based nn | 12:39 |
| lumos | mjr, o i get it | 12:40 |
| kanzure | mjr: that's discrimination | 12:49 |

| fenn | try scroogle | 20:24 |
| fenn | hm i see it too | 20:25 |
| kanzure | well if you want to do some detective work you could try deleting some lines in InitGL | 20:26 |
| kanzure | keep the one that makes the cube (with glVertex3f calls) | 20:26 |
| kanzure | and remove the other call lists | 20:27 |
| kanzure | then remove the calls to glCallList in OnDraw except for the cube | 20:27 |
| kanzure | (if that doesn't work the next step would be to move glBegin/glEnd from the cube's calllist into OnDraw and see if that works) | 20:27 |
| fenn | there's a lot of extraneous crap in InitGL | 20:28 |
| kanzure | my bet is that this error is because of the nurbs (confirmed if the cube's call list works) | 20:28 |
| kanzure | if it's because of the use of call lists themselves, then the other suggestion will work | 20:28 |
| kanzure | yes like i said this is mostly scratchpad notes.. | 20:28 |
| kanzure | thsi repository is shot to hell :p | 20:28 |
| fenn | cool | 20:30 |
| kanzure | test if it's the use of call lists: http://diyhpl.us/~bryan/irc/lolcad/visualizer-fenn-debug001.py | 20:31 |
| fenn | only the first glCallList(1) is causing problems | 20:31 |
| kanzure | what about the other nurbs one? | 20:31 |
| fenn | where? | 20:32 |
| fenn | what does glCallList do anyway? | 20:32 |
| kanzure | #3 | 20:32 |
| kanzure | it's a way of storing an object or model instead of re-creating it each time you want to draw it | 20:32 |
| fenn | so glNewList(1, GL_COMPILE) is executed by glCallList(1) | 20:33 |
| -!- eridu [~eridu@gateway/tor-sasl/eridu] has joined ##hplusroadmap | 20:33 | |
| kanzure | it's opengl's way of doing references | 20:34 |
| fenn | commenting out line 196 gluNurbsSurface(... fixes it | 20:35 |
| kanzure | but.. but.. | 20:36 |
| kanzure | gluNurbsCurve works for you but not gluNurbsSurface.. bizarre | 20:36 |
| kanzure | i hope this is driver related | 20:36 |
| kanzure | sudo pip install PyOpenGL-Demo | 20:37 |
| kanzure | once you grab it, go into your /usr/lib/pythonwhatever/site-packages/PyOpenGL-Demo/ folder and find the molehill.py demo and see if that runs | 20:38 |
| kanzure | (it uses gluNurbsSurface) | 20:38 |
| fenn | i cant figure out where pip put it | 20:43 |
| kanzure | python -c'import math; print math.__path__' | 20:43 |
| fenn | cd /usr/lib ; find -iname '*gl*' doesn't show any demos | 20:43 |
| kanzure | oops i meant __file__ | 20:44 |
| fenn | math isn't in a file like other modules anyway | 20:45 |
| fenn | /usr/lib/python2.6/xml/__init__.pyc | 20:45 |
| kanzure | true, but it should show you /usr/lib/python2.7/something/math | 20:45 |
| kanzure | you need /usr/lib/python2.6/site-packages/PyOpenGL-Demo/ | 20:45 |

| fenn | /usr/local/lib/python2.6/dist-packages/PyOpenGL-Demo | 20:47 |
| kanzure | http://pypi.python.org/packages/source/P/PyOpenGL-Demo/PyOpenGL-Demo-3.0.1b1.tar.gz#md5=d4edda5a8bac139dde2e2700fd7e1d5e | 20:48 |
| kanzure | ok find . | grep molehill | 20:48 |
| fenn | molehill throws the same error | 20:48 |
| kanzure | hooray it's not my fault | 20:48 |
| kanzure | ok time to figure out your computer's specs and drivers.. | 20:48 |
| fenn | there ought to be some command that just dumps all the relevant info | 20:50 |
| kanzure | glxinfo | 20:50 |
| fenn | that doesnt even say the driver name | 20:50 |
| kanzure | my glxinfo: http://pastebin.com/e2DdEkqw | 20:50 |
| fenn | oh here we go | 20:51 |
| fenn | OpenGL renderer string: Mesa DRI Intel(R) 945GME GEM 20100330 DEVELOPMENT x86/MMX/SSE2 | 20:51 |
| kanzure | huh i'm not using mesa? | 20:51 |
| kanzure | mesa has the same gluNurbsSurface implementation as the sgi proof | 20:51 |
| fenn | my glxinfo http://pastie.org/2109437 | 20:52 |
| kanzure | out of curiosity.. what modules do you have in your xorg.conf | 20:54 |
| fenn | it's autogenerated | 20:54 |
| kanzure | i use: dbe, record, extmod, glx, dri2 (obviously glx is the one that matters) | 20:54 |
| fenn | i can show you Xorg.0.log if you want | 20:54 |
| kanzure | i wouldn't know what to do with it | 20:54 |
| kanzure | maybe ##opengl will be able to help us? jules seems cranky at the moment | 20:55 |
| kanzure | 20:55:14 omg/jblake: stop using nurbs | 20:55 |
| fenn | extmod, dbe, glx, record, dri, dri2, intel_drv, vesa_drv, fbdev_drv, fbdevhw, evdev | 20:56 |
| kanzure | http://diyhpl.us/~bryan/irc/lolcad/visualizer-fenn-debug002.py | 20:58 |
| kanzure | this time there are no call lists, only the nurbs calls | 20:59 |
| fenn | is there a C demo? i expect ##opengl will get pissy and start focusing on the python library | 20:59 |
| kanzure | try debug002 | 20:59 |
| fenn | debug002 works, is very slow | 21:00 |
| fenn | especially at high zoom | 21:00 |
| kanzure | it's calling gluNurbsSurface in OnDraw directly | 21:00 |
| kanzure | THIS IS WHY YOU USE CALL LISTS | 21:00 |
| kanzure | but for some reason that's broken? | 21:00 |
| -!- JaredW [~JaredW@118.142.17.238] has joined ##hplusroadmap | 21:00 | |
| fenn | yeah but it's faster when the nurbs surface is small, so i assume it's the actual rendering part that is slow | 21:00 |
| kanzure | gluNurbsSurface is doing some cpu-side tessellation actually.. | 21:01 |
| fenn | oh | 21:01 |
| fenn | so if you have a calllist that starts small and gets big you will see polygons? | 21:02 |
| kanzure | what | 21:02 |
| kanzure | oh | 21:02 |
| kanzure | uh.. yes | 21:02 |
| kanzure | you also set the sampling | 21:02 |
| kanzure | see GLU_SAMPLING_TOLERANCE in the file | 21:02 |
| -!- jmil [~jmil@pool-173-59-78-69.phlapa.east.verizon.net] has quit [Quit: jmil] | 21:03 | |
| kanzure | i spent four shameful hours trying to figure out why GLU_SAMPLING_TOLERANCE=50 was making octograms | 21:03 |
| kanzure | and then i jumped for joy when i figured it out and proceeded to spend the next 2 hours fixing the same exact problem elsewhere | 21:03 |
| -!- eridu [~eridu@gateway/tor-sasl/eridu] has quit [Quit: Leaving] | 21:04 | |
| fenn | http://fennetic.net/irc/lolcad.png | 21:04 |
| kanzure | that looks all wrong | 21:05 |
| fenn | yeah i figured | 21:05 |
| fenn | the green stuff | 21:05 |
| kanzure | it should be more like: | 21:05 |
| kanzure | http://heybryan.org/shots/2011-06-22-cylinder-before.png | 21:05 |
| kanzure | circular cylinder | 21:05 |
| kanzure | red circle enclosed in a white box | 21:05 |
| fenn | why is the cylinder red? | 21:05 |
| kanzure | because i moved code around in debug002 quickly without thinking | 21:06 |
| kanzure | glColorf applies to everything written after it | 21:06 |
| kanzure | try decreasing the sampling tolerance from 1 to 0.1 and see if that smooths out your cylinder | 21:07 |
| fenn | so that's supposed to be a circle inside the square? | 21:07 |
| fenn | because it always looked sorta lumpy | 21:07 |
| kanzure | sampling again.. | 21:07 |
| kanzure | the nurbs evaluator is being fennicky | 21:07 |
| fenn | nope same thing | 21:09 |
| kanzure | what was your change | 21:09 |
| fenn | changed both lines that mentioned sampling to 0.1 | 21:10 |
| fenn | http://fennetic.net/irc/lolcad_sampling_0.1.png | 21:10 |
| fenn | it looks more like a fat cube with the ends cut off | 21:10 |
| kanzure | the truth: http://heybryan.org/shots/2011-06-23-lolcad.png | 21:11 |
| fenn | molehill.c works | 21:14 |
| fenn | so problem is in pyopengl | 21:16 |
| kanzure | jules suggests i try buffer objects | 21:17 |
| kanzure | instead of display lists (or what i was calling 'call lists') | 21:17 |
| kanzure | s/suggests/demands/ | 21:17 |
| kanzure | in your case you have other issues too | 21:18 |
| kanzure | i'm p. sure my control points and knots for UnitCircle in nurbs.py is correct | 21:18 |
| fenn | omfg sourceforge is so terrible | 21:19 |
| fenn | okay what info should i include in my bug report? | 21:27 |
| kanzure | minimal example | 21:35 |
| kanzure | point to molehill | 21:35 |
| kanzure | http://gnusha.org/logs/2011-06-23.log while you're at it.. | 21:36 |
| kanzure | who are you complaining to? | 21:36 |
| fenn | pyopengl | 21:39 |
| fenn | well apparently SF lost my account, bastards | 21:39 |

| fenn | they reset their passwords 'just in case' but you can only send confirmation for one account per email address, and both accounts were on the same email address | 21:40 |

| kanzure | but otherwise good luck with that | 21:41 |

| kanzure | ok i guess i should sleep | 22:09 |
| kanzure | fenn if you want to play around with buffer objects that would be cool | 22:09 |
| kanzure | or attempt to figure out why your circles are not circles | 22:10 |
| fenn | uh, i will wait and see what the pyopengl people say | 22:10 |
| kanzure | are they activew | 22:12 |
| kanzure | to be fair i will probably not use display lists since jules suggests otherwise | 22:12 |
| kanzure | he is usually right about these things since all his friends are X developers or something | 22:12 |
