| --- Day changed Wed Dec 17 2008 | ||
| fenn | i think you want something like my "arc length parameterized spiral" function: http://fennetic.net/pub/irc/spiral3.png http://fennetic.net/pub/irc/lengthspiral.py | 00:01 |
|---|---|---|
| fenn | G3 is gcode for arc, btw | 00:02 |
| kanzure_ | http://heybryan.org/bioreactor/membraneless_filtration/2008-12-16_spiral_generator_2_other_issue.png | 00:03 |
| kanzure_ | obviously something wrong^ | 00:03 |
| fenn | is it supposed to be a hollow tube? | 00:03 |
| kanzure_ | yes | 00:03 |
| fenn | and if so, why not use brlcad's tube primitive | 00:03 |
| kanzure_ | not with cross-sections rotated around, what's going on there anyway | 00:03 |
| kanzure_ | the xy coords are set to the spiral coords, nothing about rotation | 00:04 |
| fenn | eh? the rectangles aren't being rotated | 00:04 |
| fenn | so.. rotate them | 00:04 |
| kanzure_ | no, they're not supposed to be | 00:04 |
| kanzure_ | but look at the screenshot | 00:04 |
| kanzure_ | (the other_issue) | 00:04 |
| fenn | explain yourself! | 00:04 |
| kanzure_ | http://heybryan.org/bioreactor/membraneless_filtration/2008-12-16_spiral_generator_2_other_issue.png | 00:05 |
| kanzure_ | look at the tail | 00:05 |
| kanzure_ | something must be wrong. | 00:05 |
| kanzure_ | however, | 00:05 |
| fenn | the inside end? | 00:05 |
| kanzure_ | no, outside | 00:05 |
| kanzure_ | http://heybryan.org/bioreactor/membraneless_filtration/2008-12-16_spiral_generator_2.png | 00:05 |
| kanzure_ | that's a screenshot from the same dataset | 00:05 |
| kanzure_ | where they are rotated correctly | 00:05 |
| kanzure_ | explain this voodoo magic to me. :( | 00:06 |
| fenn | they aren't rotated correctly, the camera viewpoint just makes it look sorta almost correct | 00:06 |
| kanzure_ | but I can zoom in there and rotate around and it's right | 00:07 |
| fenn | show me | 00:07 |
| kanzure_ | the _2.png shot (last link I gave, just a few moments ago) | 00:08 |
| fenn | in _2 the rectangles are still aligned parallel to each other, they arent rotating around the spiral | 00:09 |
| kanzure_ | wait, what? that's good, but you say "still" as if in the other_issue they are as well? | 00:09 |
| fenn | it's the same data set | 00:09 |
| fenn | you are looking at them from two angles 90 degrees apart | 00:10 |
| fenn | i suggest taking a walk | 00:11 |
| kanzure_ | oh wait. maybe I should be rotating the cross sections w/ pi? | 00:11 |
| fenn | theta | 00:11 |
| kanzure_ | erm, yes, a variable | 00:11 |
| kanzure_ | heh' | 00:11 |
| * fenn looks at the nasty perl code | 00:11 | |
| * kanzure_ adds an orot $j 0 0; before the accept; | 00:12 | |
| fenn | der... the code changed on me | 00:12 |
| kanzure_ | but this might not actually do the trick because orot tends to hate me so far | 00:12 |
| kanzure_ | oops, I should have announced that. | 00:13 |
| fenn | oh spiral_generator.pl not spiralgen.pl | 00:13 |
| kanzure_ | heh, yes. | 00:13 |
| fenn | so, given: $x = $j*cos($j); $y = $j*sin($j) | 00:14 |
| fenn | j is the parameter | 00:14 |
| kanzure_ | as I said above, orot :) | 00:14 |
| fenn | yeah but you might change the parameter later, so you should have something like $angle = $j | 00:15 |
| fenn | uh, why arent you using "t" as the parameter? | 00:16 |
| kanzure_ | do you have brlcad installed? it's easier if you just run the script instead of me uploading a 5 MB data set. | 00:16 |
| kanzure_ | I guess orot isn't really doing anything | 00:17 |
| fenn | i know how it works | 00:17 |
| kanzure_ | when I was playing around in brlcad, orot doesn't play with 'regions', only shapes. | 00:17 |
| kanzure_ | guess I'll rotate before I make it a region. bleh. | 00:17 |
| fenn | i have brlcad "sorta" installed, meaning there's all this crap in a huge directory but it won't run | 00:18 |
| kanzure_ | did you compile from sources? | 00:18 |
| fenn | oh nm i just need export PATH=$PATH:/usr/brlcad/bin | 00:18 |
| fenn | except it's in /usr/local.. | 00:19 |
| kanzure_ | it took me the longest time to remember that the whole PATH=$PATH thing required :'s and not ;'s.. | 00:19 |
| gene | I really don't think we should be using brlcad to simply put down prims | 00:20 |
| fenn | i have no idea what the purpose of this exercise is, so no comment | 00:21 |
| kanzure_ | oh, maybe I should be using 'comb' instead of r, and then using orot | 00:21 |
| * kanzure_ tests | 00:21 | |
| gene | excellent | 00:21 |
| gene | the purpose is free energy fenn | 00:22 |
| fenn | oh i bet | 00:25 |
| kanzure_ | nope, didn't work. I'll go take that walk [down to the kitchen]. | 00:26 |
| fenn | btw when you get back, before you thrash everything, might i suggest putting it in a git repo so you can go back to something that sorta works | 00:27 |
| fenn | and try to understand my little python program please ;) | 00:31 |
| fenn | i suppose i could fix it to work standalone, using cairo for graphics | 00:45 |
| fenn | lengthspiral now in standalone-ish, in: http://fennetic.net/git/cxf2cnc.git/ | 01:26 |
| fenn | need to figure out wtf i'm doing with arcs | 01:27 |
| fenn | and a pic for you lazies: http://fennetic.net/pub/irc/lengthspiral.png | 01:29 |
| fenn | ignore the green crap | 01:29 |
| bkero | I'm free energy. | 02:07 |
| kanzure_ | fenn, what's lengthspiral.png supposed to be helping with? | 02:13 |
| bkero | http://www.eatliver.com/i.php?n=3723 | 02:24 |
| kanzure_ | bkero: Rock on. | 02:26 |
| kanzure_ | grr, I need a better stl viewer. | 02:49 |
| kanzure_ | right now I can only rotate, move the entire object left/right, and zoom in/out. | 02:49 |
| kanzure_ | but I'd rather be able to do some flying around. | 02:49 |
| fenn | kanzure_: the bunching up at the center / spreading out at the edges | 02:54 |
| kanzure_ | aha] | 03:38 |
| kanzure_ | *aha | 03:38 |
| bkero | Kill people | 03:39 |
| ybit | grr, was not on logging | 03:54 |
| ybit | oi bryan, wher's the jap paper speaking about "fmri_extracts_images_from_the_brain"... | 03:55 |
| ybit | Kang Cheng site:heybryan.org gives me nothing | 03:57 |
| ybit | well, not what i'm looking for | 03:57 |
| ybit | nor does RIKEN | 03:57 |
| ybit | hmm, kanzure kanzure_ | 04:03 |
| ybit | :) | 04:03 |

| kanzure_ | http://www.overcomingbias.com/2008/12/visualizing-eutopia.html#comment-142880728 | 04:55 |
| kanzure_ | this is like reading a brick wall. Some people seem to have the right idea when commenting, but nobody ever replies to them. | 04:55 |
| UtopiahGHML | http://nnlm.gov/pnr/dragonfly/2008/12/09/lifesci_search/ Alternative Search Engines for the Life Sciences | 05:00 |
| UtopiahGHML | think Eliezer Yudkowsky is more engaged in preaching in a dogmatic way that engaging with a dialog with "the masses" | 05:01 |
| UtopiahGHML | his quality of thinking is too precise and thus precious to be wasted on debates | 05:02 |
| bkero | I went to Boston this week and met Benjamin Mako Hill. :) | 05:03 |
| UtopiahGHML | (he is most likely applying http://insti.physics.sunysb.edu/~siegel/quack.html with his own quality metrics though, makes sense) | 05:05 |
| kanzure_ | ybit: http://www.overcomingbias.com/2008/10/economic-defini.html#comment-136930723 | 05:17 |
| edektor | anybody there? | 05:35 |
| kanzure_ | http://heybryan.org/eli.html <- Some notes on attempting to knock sense into Eliezer. | 05:39 |
| kanzure_ | There. Now I can stop complaining (right)?. | 05:39 |
| fenn | anyone want the rexresearch.com comprehensive hogwash database? | 05:44 |
| fenn | covering free energy, reactionless propulsion, water from air, etc | 05:44 |
| fenn | gene you know you want it | 05:44 |
| gene | no, I'm much too smart for that | 05:45 |
| edektor | How is the SynBio Book coming? | 05:46 |
| gene | I'll find myself deconstructing the bad physics of movies rather than watching them sometimes | 05:46 |
| edektor | Anybody? | 05:48 |
| fenn | what synbio book? | 05:48 |
| fenn | cool he even has a babington burner article | 05:50 |
| edektor | This book: http://groups.google.com/group/diybio/browse_thread/thread/6db3f4867ba006a4?pli=1. I dont know current status of the project though. | 05:51 |
| fenn | oh was this mackenzie's project? | 05:51 |
| fenn | meh | 05:52 |
| fenn | i've enough unfinished projects of my own | 05:52 |
| edektor | no Bryan Bishop's | 05:53 |
| fenn | i think he was just "providing a place" to get things started for people running around like headless chickens | 05:53 |
| edektor | are you sure? | 05:55 |
| edektor | I dont think so? | 05:55 |
| bkero | No such thing as too many projects ;) | 05:55 |
| edektor | You guys still working on the DIY Syn Bio book? | 07:09 |
| fenn | haha my mom got a twitter account | 07:19 |
| bkero | I have tons of random people following me on twitter | 07:39 |
| bkero | I'll get two or three messages a day saying someone has started to follow me | 07:39 |
| willPow3r | fenn, mind if i twitter your mom? | 07:47 |
| willPow3r | http://www.eurekalert.org/pub_releases/2008-12/osoa-eat121608.php | 07:56 |
| fenn | that's interesting | 07:57 |
| fenn | i wouldnt think they compete for light by shading out others since most of the cells nearby would be related (clones) | 07:58 |
| ybit | [23:17] <kanzure_> ybit: http://www.overcomingbias.com/2008/10/economic-defini.html#comment-136930723 | 08:08 |
| ybit | ^ your point? | 08:08 |
| ybit | is this part of your collection of jef's comments? | 08:08 |
| kanzure_ | ybit: http://xkcd.com/512/ | 14:24 |
| kanzure_ | "the distribution of leukemia among children living hear high voltage | 15:24 |
| kanzure_ | power lines or transformers is not random; rather, it affects children | 15:24 |
| kanzure_ | carrying a certain genetic variant--that is, the ability to repair DNA | 15:24 |
| kanzure_ | breaks--vastly more often." | 15:24 |
| kanzure_ | "Now from | 15:56 |
| kanzure_ | Turberfield's group comes a paper showing that DNA has the potential not | 15:56 |
| kanzure_ | just to make static structures, but to make functioning machines." | 15:56 |
| kanzure_ | http://ftp.aip.org/epaps/phys_rev_lett/E-PRLTAO-101-091848/Coordinated_chemomechanical_cycles_EPAPS.pdf | 15:56 |
| drazak | that paper must be oldish | 16:25 |
| kanzure_ | ok, I've expanded it: | 17:44 |
| kanzure_ | http://heybryan.org/eli.html | 17:44 |
| kanzure_ | now with actual content instead of a ridiculous number of links | 17:44 |
| ybit | :) | 18:17 |
| ybit | thanks | 18:17 |
| kanzure_ | Does anybody know why browser HTML layout engines are so nasty to write, and why we bothered making crappy things so standardized? Anybody? | 20:06 |
| kanzure_ | http://mathstat.helsinki.fi/openbugs/Home.html BUGS (Bayesian inference Using Gibbs Sampling) is a piece of computer software for the Bayesian analysis of complex statistical models using Markov chain Monte Carlo (MCMC) methods. It has been developing and maturing over the years, and is probably best known in its WinBugs incarnations. The latest version can run on Windows and Linux, as well as from inside the R statistical package. | 21:23 |
| kanzure_ | http://mathstat.helsinki.fi/openbugs/ | 21:23 |
| Phreedom | kanzure_: why do you think html layout is crappy? | 21:29 |
| Phreedom | and a typical layout engine is a contstraint propagation solver | 21:30 |
| Phreedom | no more and no less | 21:30 |
| fenn | supposedly DNA is superconductive | 22:51 |
| fenn | even if not, there are a lot of turns in those coils, making for a high ratio transformer | 22:52 |
| fenn | so i don't think it's totally unreasonable to assume that magnetic fields could affect DNA | 22:52 |
| fenn | the thing is, high voltage power lines don't carry that much current | 22:53 |
| gene | DNA is superconductive | 23:42 |
| gene | ??? | 23:43 |
| fenn | no not really | 23:56 |
| fenn | but it appears to be if you use rhenium electrodes | 23:56 |
| fenn | of course this makes one wonder why nobody's jumping on the rhenium-doped-DNA bandwagon | 23:57 |
