kanzure | Hey Smari. | 10:06 |
kanzure | http://www.cognitiveliberty.org/shulgin/blg/index.html Shulgin's blog | 10:08 |
Smari | y0 | 10:14 |
Smari | I think one of the fiber optics out of Iceland just got fucked. | 10:14 |
kanzure | pymates.transform_point(-1.5,0,0) #transform_point() takes some coords and displays what it is like after the transform. x=-1.5 is required to get it aligned with the block-hole feature. | 10:24 |

splicer-afk | Smari: it was apparently cut 17 times between 2003 and 2005, that's... a lot | 10:30 |
Smari | Yea | 10:31 |
splicer-afk | there really is only one fiber cable? | 10:31 |
Smari | No, there's three now. | 10:32 |
Smari | CANTAT-3, FarIce and DanIce. | 10:32 |
splicer-afk | sounds like a good idea | 10:32 |
Smari | But they're owned by different entities, all of which are overpricing access to them, and none of which are actually thinking of Internet as Infrastructure.. | 10:33 |
Smari | CANTAT-3 goes from the US to the UK, via Newfoundland, Iceland and the Faeroe Islands... it is, IIRC, 3x45MB, which was enough back in the day but sucks now... | 10:34 |
Smari | FarIce is a pretty fat pipe but it's severely overpriced - about three times as expensive to use as CANTAT-3, and all price deals are secret so different users have different deals... really annoying. | 10:35 |
splicer-afk | MB as in mega bytes? | 10:35 |
Smari | Yes. | 10:35 |
Smari | But I meant Megabits, sorry. :) | 10:35 |
splicer-afk | ; ) | 10:35 |
Smari | DanIce is new, taken into use on the 17th of June this year, it's fairly fat but intended only as a backup line. | 10:35 |
splicer-afk | hehe... doesn't make all that much difference | 10:35 |
Smari | Hey, it's 8 times less! | 10:36 |
splicer-afk | yeah but ; ) | 10:36 |
Smari | So long story short here is that we're severely underconnected. I know some folks who're working on a couple of lines that I can't talk about publicly yet, but there's a push to try and fix this shit. | 10:36 |
splicer-afk | I think it's a common problem... that politicians don't understand that it's infrastructure | 10:37 |
Smari | mhm | 10:38 |
Smari | It appears that the roof of the garage at home just collapsed. Nice. | 10:38 |
Smari | what the hell is happening today? | 10:39 |
splicer-afk | the solar eclipse | 10:39 |
splicer-afk | the end is neigh | 10:39 |
Smari | Ah, just got confirmation: CANTAT-3 is officially down. | 10:41 |
splicer-afk | has kurzweil set a date for the robot uprising btw? | 10:41 |
splicer-afk | (that's a very long cable CANTAT-3 ) | 10:45 |
Smari | Yes | 10:46 |
Smari | The failure seems to be... in Germany. | 10:46 |
splicer-afk | hehehe | 10:47 |
kanzure | hm why doesn't my mysql db have a root username? | 11:10 |
kanzure | also, why am I using mysql? | 11:10 |
Smari | kanzure, mysql is good | 11:15 |
Smari | root isn't important. | 11:16 |
fenn | are there constraint languages for describing how geometry is related to other geometry? | 11:20 |
Smari | There's some constraint stuff in povray. | 11:21 |
fenn | i'm hoping for something a less implementation dependent | 11:22 |
Smari | hm. | 11:22 |
Smari | that might be difficult. | 11:22 |
Smari | Considered writing your own? | 11:22 |
Smari | I'd love to see a very easy to use constraint system in Python :) | 11:23 |
fenn | absolutely not | 11:23 |
fenn | that's geo_1005's job | 11:23 |
fenn | er, geo01005 | 11:23 |
Smari | geo01005? | 11:24 |
fenn | guy who's writing a constraint system for heekscad | 11:24 |
Smari | ah | 11:24 |
fenn | i'm just trying to say stuff like "the bandsaw must be perpendicular to the workpiece face" | 11:24 |
fenn | but in a way i can apply it to geometry | 11:24 |
fenn | hopefully someone has done all the hard thinking for me already | 11:25 |
kanzure | crud. I don't have a recent backup of the heybryan.org wiki. | 11:33 |
kanzure | does anyone have the database? | 11:33 |
fenn | good lord do i really have to go back to sutherland's SKETCHPAD just to get some decent theory | 11:34 |
kanzure | gah did I really just spend an hour yelling at mysql? | 11:37 |
kanzure | apparently mysqld --init-script is a kinda important option to know abou | 11:38 |
kanzure | *about | 11:38 |
kanzure | nobody use the wiki for now please. I'll be replacing the database (hopefully tonight) | 11:38 |
CIA-44 | skdb: kanzure * r88648679048a /pymates/pymates.py: transform_point now works properly | 11:49 |

kanzure | fenn: why didn't your changes show up via CIA? | 11:49 |
fenn | which changes? | 11:52 |
fenn | how do i diff to a remote repository? | 11:52 |
fenn | or at least diff the logs | 11:53 |
kanzure | git log -p ? | 11:54 |
CIA-44 | skdb: kanzure * rbca8bfee467c /pymates/pymates.py: typos fixed, translation in part mating completed | 11:54 |
kanzure | now to do rotation. | 11:54 |
CIA-44 | skdb: * r28e0ab71c376 /processes.yaml: constraintify path geometry for sweep | 11:54 |

kanzure | no username? | 11:55 |
CIA-44 | skdb: * rb8cbbcb00a66 /change.txt: testing cia author bug | 12:00 |
fenn | hm | 12:00 |
fenn | do you get "Use of uninitialized value $user in concatenation (.) or string at /var/www/skdb.git/ciabot_git.pl line 192." when you push | 12:00 |
kanzure | only sometimes | 12:01 |
kanzure | a few days ago I was getting that | 12:01 |
kanzure | but I didn't get that today | 12:01 |
fenn | maybe because my email doesnt have an @ sign? | 12:02 |
fenn | ($user) = $author =~ /<(.*?)@/; | 12:03 |
kanzure | why is it taking it from the email? it should be taking it from the username | 12:03 |
kanzure | the author name I mean | 12:03 |
fenn | right above that it says # XXX: Too trivial this way? | 12:03 |
kanzure | if I committed as "Bryan Bishop (kanzure@gmail.com)" would it still say kanzure? | 12:04 |
kanzure | so if I SetTranslation() and SetRotation(), that should cover everything that campbell was talking about? | 12:12 |
fenn | no | 12:13 |
fenn | you need two rotations, and the order matters | 12:13 |
fenn | which is why campbell wants a matrix, because the order doesnt matter (there's only one step) | 12:14 |
kanzure | so how do you determine the order? | 12:15 |
fenn | as long as the order is the same every time, it doesn't matter | 12:16 |
kanzure | you mean: x rotation first, then y rotation | 12:16 |
fenn | this is an arbitrary thing that has caused mathematical bloodshed over the ages | 12:16 |
kanzure | like that? | 12:16 |
fenn | like row, column vs column, row | 12:16 |
fenn | matrix notation | 12:16 |
kanzure | you mean matrix notation has caused bloodshed | 12:16 |
kanzure | not "x rotation first, then y rotation" | 12:17 |
fenn | both | 12:18 |
* Smari is a proud owner of an ASUS EEEPC 1005HA. | 12:18 | |
kanzure | fenn: but me setting my foot down and saying "first one then the other" will be the solution, yes? | 12:18 |
fenn | meh | 12:18 |
fenn | talk to campbell, not me | 12:18 |
kanzure | this isn't a philosophical question | 12:18 |
fenn | i said do rotations in the first place | 12:19 |
kanzure | what? | 12:19 |
kanzure | should probably look at the opengl superbible tonight | 12:20 |

CIA-44 | Tangiblebit: spm * rd4b88cd58e3d /tangiblebit.com/ (6 files in 4 dirs): XML and YAML exporters for Site model. XML Conforms to site.dtd. XMLRPC interfaces for fetching also implemented. | 13:41 |
kanzure | what's tangiblebit.com/sources/templates/fabmap/site.yaml for? I see the contents, but I'm not sure why you made it | 13:52 |
Smari | kanzure, it's a template | 13:53 |
Smari | kanzure, it's used by one of the views to generate YAML site listings. | 13:54 |
kanzure | ah okay the view outputs YAML | 13:54 |
Smari | yes | 13:54 |
Smari | So I just spent some time figuring out how I'd make the thing speak XML and YAML sensibly. | 13:54 |
Smari | Didn't arrive at an acceptable solution. | 13:54 |
Smari | but I did at least get two examples done. | 13:55 |
Smari | I want a very general function that just says what you want to output and in which format and it just solves the problem. | 13:55 |
Smari | currently I don't have that, but I'm close. | 13:55 |
Smari | Anyway. Dinner time. More fun soon. | 13:55 |

fenn | what template language is that? | 13:59 |
kanzure | that's django's internal stuff | 13:59 |
kanzure | they use their own custom language | 13:59 |
fenn | hmm | 13:59 |
ybit | 18:55 < xp_prg> Africa is a third world country and needs to save money so medical equipment is cheaper | 14:01 |
ybit | :P | 14:01 |
ybit | xp_prg: you made me laugh | 14:01 |
ybit | ty | 14:01 |
kanzure | ybit: fenn and I couldn't stop laughing :/ | 14:02 |
kanzure | ok, just me really | 14:02 |
fenn | can django views return other stuff besides text based formats? like can you run a command and return the result? | 14:02 |
kanzure | fenn: yep | 14:02 |
kanzure | fenn: it's all python. check out djangit/wiki/views.py | 14:02 |
ybit | sam rose is a student at utexas? | 14:03 |
kanzure | no | 14:03 |
ybit | he is in the area though right? | 14:03 |
kanzure | no | 14:03 |
ybit | not in texas | 14:03 |
fenn | dearborn michigan i think | 14:03 |
ybit | must have misread | 14:03 |
kanzure | that's definitely not texas | 14:03 |
ybit | something about running a usb drive by of the matweb scrape | 14:03 |
kanzure | oh crud. didn't do that today :( | 14:04 |
ybit | 14:16 < kanzure> you'll get it in about 10 seconds from adl.serveftp.org once I bring it in on a flash drive | 14:04 |
fenn | pigeons per TB is at an all time low | 14:04 |
ybit | took that to mean he was nearby | 14:04 |
fenn | ybit: upload from the machine which had the data is slow, but from here it's fast | 14:04 |
ybit | so what does he do, he seems knowledgeable about manufacturing processes | 14:04 |
kanzure | no he doesn't | 14:05 |
kanzure | :p | 14:05 |
fenn | social web stuffs, and he helped with openfarmtech | 14:05 |
ybit | well.. he had a difficult time understanding your view, but he seems to have some background in it.. | 14:05 |
fenn | more importantly he's not an idiot and wants to help | 14:05 |
kanzure | right | 14:06 |
ybit | i was in the process of testing pymates yesterday when i instinctively decided to get smashed :-\ | 14:07 |
ybit | apparently you aren't supposed to mix alcohol and anti-depressants | 14:07 |
ybit | think i mixed about 5 diff drugs | 14:07 |
ybit | not a good idea | 14:07 |
* ybit needs a happy medium | 14:10 | |
ybit | 16:04 < Smari> you just made it hilarious to say nothing. | 14:13 |
genehacker2 | ybit, that sort of neural modification is not recommended | 14:16 |
ybit | yeah yeah | 14:17 |
ybit | thus | 14:17 |
ybit | 14:07 * ybit needs a happy medium | 14:17 |
kanzure | any guesses as to which type of angles OCC uses? degrees? radians? | 14:17 |
* kanzure assumes degrees | 14:18 | |
ybit | between using drugs (caffeine, alcohol, anti-depressants, adhd meds, mary) | 14:18 |
ybit | 11:31 < kanzure> crud. I don't have a recent backup of the heybryan.org wiki. | 14:19 |
genehacker2 | I'm guessing radians | 14:19 |
ybit | i deleted mine kanzure :-\ | 14:19 |
ybit | but fenn seems to have copied it | 14:19 |
kanzure | ybit: I have a recent backup of the heybryan.org wiki, but not on a machine that is presently turned on. | 14:19 |
ybit | okay | 14:19 |
ybit | kanzure: if i sent you a 1tb hard drive, would it be much trouble to put a mirror image of heybryan on it? | 14:20 |
genehacker2 | ILLEGAL NEUROMODIFICATION DETECTED | 14:20 |
kanzure | ybit: no trouble at all. it would be even better if it is an external hdd. | 14:20 |
ybit | or maybe i could setup a decent time to grab material from it, i.e. 2-6am | 14:21 |
kanzure | I suppose I really should fix things so that I have more speeds. | 14:21 |
genehacker2 | http://www.technologyreview.com/energy/23042/ | 14:22 |
genehacker2 | salmon dna can be quite useful I gues | 14:22 |
kanzure | printable stepper motor? | 14:40 |
genehacker2 | yes | 14:43 |
genehacker2 | a printable stepper motor | 14:43 |
genehacker2 | after all I get free 3d prints on the stratasys | 14:43 |
kanzure | how do you print magnets? | 14:44 |
genehacker2 | you don't | 14:44 |
kanzure | maybe I forget how a stepper motor is supposed to work | 14:44 |
genehacker2 | it's pneumatic | 14:44 |
kanzure | link? | 14:44 |
genehacker2 | it doesn't use electricity | 14:44 |
genehacker2 | ok good | 14:44 |
genehacker2 | forget | 14:44 |
genehacker2 | this isn't like anything you've seen before | 14:45 |
genehacker2 | it's a pneumatic wobble motor | 14:45 |
genehacker2 | damn link rot | 14:47 |
genehacker2 | http://www.act.sys.okayama-u.ac.jp/kouseigaku/research/okamoto_wobble_06/english.htm | 14:47 |
genehacker2 | anyway look up pneumatic wobble motor in IEEE | 14:48 |
kanzure | how about you archive pages so that they don't rot | 14:48 |
genehacker2 | good idea | 14:49 |

genehacker2 | oops | 14:50 |
genehacker2 | http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=00680893 | 14:50 |
genehacker2 | better | 14:50 |
genehacker2 | any way that's what I've been designing | 14:50 |
kanzure | what are you going to be using for a bladder? | 14:50 |
genehacker2 | an RTV sealant grade silicone molded bladder made from a 3d printed mold or 3d printerd | 14:51 |
fenn | kanzure: plz download this to adl so i can do some experiments on the file | 14:52 |

kanzure | huh: | 14:55 |
kanzure | http://adl.serveftp.org/papers/diytranshuman_projects.txt | 14:55 |
fenn | google rip of manufacturing processes reference guide | 14:55 |
genehacker2 | so what do you want to know about wobble motors? | 14:56 |
kanzure | how you make a bladder out of plastic | 14:56 |
genehacker2 | you don't | 14:56 |
genehacker2 | you make the molds for it | 14:56 |
fenn | why not squirt silicone goo | 14:56 |
genehacker2 | then pour RTV silicone sealant grade into the mold | 14:57 |
kanzure | can't you pump down a plastic chamber? | 14:57 |
kanzure | or ump up | 14:57 |
kanzure | *pump | 14:57 |
fenn | you've seen the fab@home silicone parts right? | 14:57 |
fenn | directly extruded silicone | 14:57 |
genehacker2 | yes | 14:57 |
fenn | why not do that instead? | 14:57 |
genehacker2 | but the reason I'm not doing that is because molded parts may end up being stronger | 14:58 |
genehacker2 | and I don't have a 3d printer that can print silicone | 14:58 |
fenn | do you have any quantitative data on the strength of deposited silicone? | 14:58 |
genehacker2 | mainly reason 2 | 14:58 |
genehacker2 | no | 14:58 |
genehacker2 | I don't | 14:59 |
genehacker2 | but yes that is an option | 14:59 |
genehacker2 | kanzure what do you mean by plastic chamber? | 14:59 |
fenn | i know platinum cured silicone is stronger in general, but maybe you could deposit that stuff too | 14:59 |
kanzure | wow first run of the simpler python with rotations instead of matrices, and it works perfectly | 15:00 |
kanzure | something must be wrong. | 15:00 |
fenn | write some unit tests | 15:00 |
genehacker2 | though with an extrusion process you could embed nylon fiber into the silicone to make it stronger | 15:00 |
genehacker2 | on? | 15:01 |
genehacker2 | oops | 15:01 |
genehacker2 | anyway that's sort of what I've been designing as of recently | 15:01 |
fenn | i think the problem would be delamination of the layers | 15:01 |
genehacker2 | yeah | 15:01 |
fenn | there's no real reason you couldnt trace a grid over the surface | 15:02 |

Overand | I'm feeling very organic today. | 15:03 |
kanzure | how are the polies? | 15:03 |

Overand | Hm. | 15:03 |
kanzure | the polyies | 15:03 |
Overand | Things are fine. | 15:03 |
Overand | my girlfriend (d8) is moving to another town in virginia | 15:04 |
Overand | going to grad school, advanced mathematics | 15:04 |
kanzure | what marks this fine occassion of you actually saying hi for once? | 15:04 |
Overand | I'm not sure. | 15:04 |
Overand | 12:21 < fenn> that's geo_1005's job | 15:04 |
Overand | that poked my nick-recognition | 15:04 |
Overand | "geo" has been a nick of mine | 15:04 |
kanzure | ah that's a fellow in #cam who is writing some software for something that fenn doesn't want to | 15:05 |
Overand | I'm tyring to get Chromium to play nicely with user scripts on linux | 15:06 |
kanzure | userscripts as in greasemonkey? | 15:06 |
Overand | that's the general idea, yes | 15:06 |

kanzure | *magic-carpet replacement | 15:06 |
kanzure | hi samrose | 15:06 |
Overand | Chromium as in the FOSS chunk of Google Chrome (browser) | 15:07 |
samrose | howdy | 15:07 |
kanzure | Overand: ah, well that's a namespace conflict I guess | 15:07 |
kanzure | oh well | 15:07 |
Overand | Is this the other app you're referring to? | 15:08 |
Overand | http://www.reptilelabour.com/software/chromium/ | 15:08 |
genehacker2 | awesome | 15:08 |
kanzure | no, there's something like magic-carpet and xinerama named 'chromium' or something | 15:08 |
Overand | magic-carpet as in the bullfrog game? | 15:09 |
genehacker2 | scraped a paper from the computer I did a presentation on today | 15:09 |
kanzure | xinerama is used for configuring multiple monitors | 15:09 |
Overand | That I am aware of | 15:09 |
Overand | I'm not finding this thing you're describing. | 15:10 |
genehacker2 | and it's about the environmental effects of solid freeform fabrications | 15:10 |
Overand | Ahhh. | 15:10 |
Overand | That actually sounds slightly familiar | 15:10 |
Overand | apparently the 'chromium' namespace is more crowded than you realized =] | 15:10 |

ybit | are there plans online which you have in mind for this cnc (similar to http://www.engadget.com/2006/07/11/how-to-build-your-own-cnc-machine-part-3/) or are you just winging it since it's a relatively simple machine to build | 18:19 |

kanzure | no, I got it | 19:06 |
kanzure | just need to boot up the other machine now I guess | 19:06 |
Lone_Wanderer | splicer-afk: you don't need to reinstall mysql, you can kill it and restart it with the --skipping-grant-tables option | 19:07 |
Lone_Wanderer | then you can log in with no pw at all and reset the root pw for it | 19:07 |
Lone_Wanderer | of course, kill -9ing mysql runs the risk of interrupting any query that's in progress, so you'll want to do an integrity check on the tables afterward | 19:07 |

kanzure | http://www.zotero.org/support/dev/overview_of_zotero_and_the_technologies_it_uses | 19:22 |
* samrose reading | 19:23 | |
kanzure | er it's the block of text near the bottom | 19:23 |
samrose | kanzure, that is just referring to an error reporting mechanism that reports back to zotero | 19:24 |
samrose | wait | 19:25 |
samrose | I see | 19:25 |
kanzure | ew it seems to be a collection of JavaScript files | 19:25 |
kanzure | it's in zotero/translators/ | 19:25 |
samrose | what you are saying | 19:25 |
kanzure | svn co https://www.zotero.org/svn/extension/trunk/ zotero | 19:25 |
kanzure | look at the javascript files in there | 19:25 |
kanzure | god this sucks | 19:25 |
samrose | I am googling now to see if I can find URL to central repo | 19:27 |
Smari | Lone_Wanderer, evil. | 19:27 |
samrose | kanzure could be these http://www.zotero.org/styles | 19:27 |
samrose | kanzure looks like those are style repos | 19:28 |
kanzure | no | 19:29 |
kanzure | I think you should look at the files in the repository instead. | 19:29 |
kanzure | I already found them. it's no big deal. | 19:29 |

kanzure | ybit: pythonOCC | 19:32 |

kanzure | ybit: no | 19:33 |
ybit | i was actually looking for occ.gp in pythonocc dirs, but nothing came up | 19:34 |
kanzure | ybit: it's OCC.gp btw | 19:34 |
ybit | right | 19:34 |
kanzure | ybit: did you install pythonocc successfully? | 19:34 |
ybit | yeah | 19:34 |
ybit | not a problem | 19:34 |
ybit | i even drew a line or two :P | 19:34 |
kanzure | wtf? | 19:35 |
kanzure | and you didn't have OCC.gp? | 19:35 |
kanzure | how did you draw a line if you couldn't use OCC.gp.gp_Pnt() ? | 19:35 |
ybit | aha NLPlate.py TopTrans.py | 19:35 |
ybit | ChFi2d.py OSD.py TopoDS.py | 19:35 |

ybit | -aha | 19:35 |
kanzure | which version of python are you using? | 19:35 |
ybit | 2.6.2 | 19:35 |
kanzure | did you check your /usr/lib/python2.6/site-packages/ ? | 19:36 |
ybit | gp.py exists, close | 19:36 |
kanzure | where does it exist? | 19:36 |
ybit | ~/builds/pythonOCC-wo0.2/src/OCC | 19:36 |
kanzure | er, did you run python setup.py install? | 19:36 |
ybit | for pyobjects? | 19:37 |
kanzure | or if you used scons, did you run scons mode=install | 19:37 |
kanzure | when compiling pythonocc | 19:37 |
ybit | oh wait for pythonocc, yeah i did | 19:37 |
ybit | i used setup.py | 19:37 |
kanzure | can you do "import OCC" ? | 19:37 |
ybit | yeah | 19:37 |
kanzure | you have bpython yet? | 19:37 |
ybit | well i could -_- | 19:37 |
ybit | yeah | 19:37 |
samrose | kanzure have you tried this?: | 19:37 |
samrose | Click on the Actions menu in the Zotero window (the gear icon), then select Preferences... -> General -> Miscellaneous -> Automatically attach associated PDFs and other files when saving items. | 19:37 |
ybit | hmm, maybe something was deleted | 19:37 |
kanzure | type "import OCC." and see what comes up | 19:38 |
kanzure | samrose: yes I already do that | 19:38 |
kanzure | samrose: I am very disinterested in using firefox forever however | 19:38 |
ybit | ImportError: No module named OCC | 19:38 |
ybit | something to do with PATH i'm guessing | 19:38 |
kanzure | ybit: yeah something is wrong :) | 19:38 |
kanzure | there's also a PYTHON_PATH or something | 19:38 |
samrose | how do you think that I could infer that you are NOT using firefox browser, my man? | 19:38 |
ybit | right | 19:38 |
kanzure | samrose: by the autoscholar page | 19:38 |
kanzure | I said I was disinterested in using it | 19:38 |
kanzure | not that I am not using it | 19:38 |
kanzure | but anyway, yes, zotero's auto-pdf-download feature is nice | 19:39 |
kanzure | in particular autoscholar could use some zotero wrappers | 19:39 |
kanzure | preferably python zotero wrappers | 19:39 |
kanzure | but according to the javascript, it's heavily dependent on running in a browser | 19:39 |
kanzure | so I might as well right my own scraper utility (yet again) | 19:39 |
kanzure | HtmlUnit could be used for webscraping I guess | 19:40 |
kanzure | (it runs javascript, XmlHttpRequest, etc.) | 19:40 |
kanzure | ybit: figured it out? | 19:41 |
ybit | uh, no. was reading some docs on org-mode | 19:44 |
samrose | I deem this pretty big fuckin mess http://heybryan.org/projects/autoscholar/ | 19:47 |
samrose | but, if it works for you, cool | 19:47 |
kanzure | well if you have something better, please tell me about it | 19:47 |
ybit | http://k3dsurf.sourceforge.net/ :: K3DSurf is a program to visualize and manipulate Mathematical models in three, four, five and six dimensions. K3DSurf supports Parametric equations and Isosurfaces. | 19:48 |
samrose | well, just bitching aloud | 19:48 |
samrose | if you do use zotero | 19:48 |
kanzure | but zotero depends on firefox | 19:48 |
kanzure | but it shouldn't | 19:48 |
kanzure | surfraw existed a long time ago | 19:48 |
samrose | you could probably run it like a lib, which is what I assume you were talking about | 19:48 |
samrose | so, you'd pipe to ff and zotero | 19:49 |
kanzure | no | 19:49 |
kanzure | there's no reason to use firefox at all | 19:49 |
kanzure | that's a huge memory hog for something that only needs a few kilobytes | 19:49 |
samrose | I wonder if the zotero js might run without ff, with some adjustments | 19:50 |
kanzure | http://htmlunit.sourceforge.net/ | 19:50 |
samrose | this could be useful as a service for many things | 19:50 |
kanzure | why is it that you're only interested in it now | 19:51 |
kanzure | I've been yapping about this stuff to you for years :p | 19:51 |
Lone_Wanderer | kanzure: So does sciencedirect use zotero's libraries or something? | 19:51 |
kanzure | Lone_Wanderer: no | 19:52 |
kanzure | Lone_Wanderer: zotero is a firefox extension | 19:52 |
Lone_Wanderer | but it's sciencedirect's papers you want right? | 19:52 |
kanzure | it basically scrapes data from a webpage | 19:52 |
ybit | http://pastebin.com/f45617c0d :: some programs on caelinux | 19:52 |
kanzure | well, that's just one service | 19:52 |
Lone_Wanderer | oh yeah, all FF extensions are in JS afaik | 19:52 |
ybit | + a few more i added | 19:52 |
samrose | it is possible to run js as standalone program it seems | 19:52 |
samrose | if anyone cares | 19:53 |
Lone_Wanderer | long and short of it, though, is that you want to get to sciencedirect's papers without having to click on a bunch of garbage? | 19:53 |
kanzure | samrose: that's why I keep linking to htmlunit | 19:53 |
kanzure | Lone_Wanderer: more or less, yes. | 19:53 |
Lone_Wanderer | ok | 19:53 |
ybit | also... emc2 and something like pyCAM needs to go on there ( i forget the name of it) | 19:53 |
kanzure | Lone_Wanderer: so, I have this script that shares papers across my servers | 19:53 |
kanzure | ybit: cam.py | 19:53 |
samrose | htmlunit is one way, sure | 19:53 |
kanzure | Lone_Wanderer: so anyway, what I have is over 40 GB of papers from Nature | 19:53 |
Lone_Wanderer | ok | 19:53 |
kanzure | and I have this script that throws them up on my screen | 19:53 |
ybit | ah | 19:53 |
kanzure | and it's basically like "TV but for science" | 19:53 |
Lone_Wanderer | cool | 19:53 |
kanzure | anyway it would be nice to be able to use some python to keep this system running and so on | 19:53 |
kanzure | and allow people in this channel to add papers to the distribution | 19:54 |
Lone_Wanderer | "TV but for science, only REALLY for science, not that alien conspiracy theory crap that's all over the Discovery Channel these days." | 19:54 |
ybit | and gEDA & k3dsurf should go on the list.. | 19:54 |
kanzure | without having to open up firefox each time they get a citation | 19:54 |
genehacker2 | blast something's wrong with my rolamite design | 19:54 |
Lone_Wanderer | Oh, so you want to be able to get a citation and just go straight to it | 19:54 |
kanzure | Lone_Wanderer: yes | 19:54 |
kanzure | all this other website stuff is just bullshit | 19:54 |
Lone_Wanderer | but usually you have to go to sciencedirect and they make it a pain | 19:54 |
kanzure | not if you use zotero's scrapers | 19:54 |
Lone_Wanderer | oh, but zotero requires FF which you don't want to put up with either | 19:55 |
kanzure | right | 19:55 |
Lone_Wanderer | amirite? | 19:55 |
Lone_Wanderer | zotero will scrape anything, right? not just sciencedirect? | 19:55 |
kanzure | it has a library of different scraping templates | 19:55 |
kanzure | so it scrapes stuff that it knows about | 19:55 |
Lone_Wanderer | 'cause if it's a general purpose scraper than duplicating the functionality should be trivial | 19:55 |
kanzure | the "templates" are custom js for each different domain | 19:56 |
kanzure | nope, not general at all :( | 19:56 |
Lone_Wanderer | well | 19:56 |
kanzure | it scrapes the metadata too, which is nice. | 19:56 |
Lone_Wanderer | if we can find the JS for sciencedirect | 19:56 |
Lone_Wanderer | then that should tell us all we need to know | 19:56 |
kanzure | yeah but I don't care about just sciencedirect | 19:56 |
kanzure | anyway | 19:56 |
kanzure | I'll play around with htmlunit and see if it can run zotero | 19:56 |
samrose | Lone_wanderer kanzure is saying that he needs to run zotero as sort of library, and use it's capacities to extract pdf, metadata etc, but that he would like to leave behind Firefox. this is doable, but needs a way to run js as standalone code | 19:58 |
Lone_Wanderer | right | 19:58 |
kanzure | htmlunit and jython | 19:58 |
samrose | there is also http://code.google.com/p/jslibs/ though I have never used it | 19:58 |
samrose | htmlunit and jython could work well | 19:59 |
kanzure | I've been avoiding jython for some reason (I don't know why- probably a vomit reaction to java) | 19:59 |
samrose | java is actually a great programming lang | 20:00 |
Lone_Wanderer | java or javascript? | 20:00 |
samrose | Java | 20:00 |
Lone_Wanderer | Lies. You are a heathen sinner. | 20:00 |
Lone_Wanderer | </hyperbole> | 20:00 |
samrose | The problem is really JVM | 20:00 |
samrose | in my opinion | 20:01 |
Lone_Wanderer | I dislike the entire language | 20:01 |
Lone_Wanderer | personally | 20:01 |
kanzure | java was forced down my throat in high school.. *after* I learned C/C++, perl, and all sorts of other languages | 20:01 |
kanzure | so it was kind of like "I know you are bullshitting me" | 20:01 |
kanzure | and that didn't go well with javac | 20:01 |
Lone_Wanderer | But it's useful for places where you have to be able to swap out programmers | 20:02 |
Lone_Wanderer | and don't care how good they are | 20:02 |
genehacker2 | now that's odd | 20:04 |
genehacker2 | my rolamite generator should have worked | 20:06 |
kanzure | hm maybe a TopoShape_Shape() doesn't have a location | 20:11 |
kanzure | unless it's given one | 20:11 |
samrose | jslibs and htmlunit are pretty cool | 20:23 |
samrose | playing around with them for a moment | 20:23 |
kanzure | be sure to take noets | 20:25 |
kanzure | *notes | 20:25 |
samrose | from our end, we are interested in building web services, and running locally | 20:26 |
samrose | but, it doesn't really matter | 20:26 |
samrose | whether it is local or web based | 20:26 |
samrose | zotero could be a lib | 20:26 |
samrose | outside of browser | 20:27 |

kanzure | ok, s/grab/grab and parse/ | 21:42 |
genehacker2 | hey kanzure got a question | 21:46 |
kanzure | okay | 21:47 |
genehacker2 | for producing photolabile nucleosides with NPPOC-Cl are there any other chemical required other than NPPOC-Cl and nucleosides? | 21:47 |
kanzure | no I think it was just nucleoside+NPPOC -> protected nucleosides | 21:48 |
genehacker2 | and there aren't any other chemicals required for DNA synthesis | 21:49 |
kanzure | sure there are | 21:49 |
kanzure | once you deprotect the nucleosides, what do you think should happen | 21:50 |
genehacker2 | ??? | 21:50 |
fenn | yuck re: answer to #7 http://www.depressedmetabolism.com/2009/05/11/interview-with-alcor-member-david-croft/ | 21:51 |

kanzure | oh I'm a member of the society for universal immortalism already apparently | 21:52 |
kanzure | cryobaptist church! haha | 21:52 |
kanzure | "I also have a webpage for my “Cryobaptist Church” which makes the tongue in cheek assertion that salvation can be achieved by a post-mortem baptism in liquid Nitrogen." | 21:52 |
fenn | do they actually use liquid nitrogen? | 21:53 |
kanzure | at alcor? yes | 21:53 |
kanzure | also at cryonics institute (.eu) | 21:53 |
genehacker2 | 5‘-tert-butyldiphenylsilylated nucleosides | 21:53 |
fenn | i mean, once you're frozen it doesnt matter, but they dont just dip you in liquid nitrogen like a banana? | 21:54 |
kanzure | no, not at first | 21:54 |
genehacker2 | it says that they NPPOC-Cl was combined with 5‘-tert-butyldiphenylsilylated nucleosides | 21:54 |
kanzure | you're put on ice and your core temps are dropped slowly | 21:54 |
kanzure | there's this funky curve they have to follow so that ice crystals don't build up | 21:54 |
kanzure | curve is temperature drop with respect to time | 21:54 |
genehacker2 | they add cryoprotectants | 21:54 |
fenn | i froze a goldfish once.. it didnt survive | 21:54 |
genehacker2 | you didn't add cryoprotectants | 21:55 |
kanzure | genehacker2: stfu | 21:55 |
fenn | they're supposed to have built-int cryoprotectants | 21:55 |
fenn | but you have to keep them in cold water for weeks before-hand | 21:55 |
kanzure | cryoprotectants do not stop ice crystal formation | 21:55 |
fenn | and that too | 21:55 |
kanzure | also I'm not sure if these crystals form at ice water temperatures | 21:56 |
kanzure | this is more like getting near negative 200 fahrenheit | 21:56 |
genehacker2 | they slow down ice crystal formation | 21:56 |
kanzure | genehacker2: not as much as you'd think | 21:56 |
genehacker2 | dang | 21:56 |
genehacker2 | so for the most part just liquid nitrogen? | 21:56 |
kanzure | yeah after the cool down phase it's just liquid nitrogen forever | 21:57 |
genehacker2 | don't they take people to below the glass transition temperature? | 21:57 |
fenn | arent glasses defined by a cooling rate, not a particular temperature? | 21:58 |
genehacker2 | I think you might be right | 21:59 |
katsmeow-afk | it was my impression that the crystal formaton was too rapid, and too many, for any to grow to damaging size, if the freezing was done rapidly enough | 22:03 |
kanzure | huh that's weird, from what I've read you want to freeze *slowly* | 22:05 |
kanzure | not rapidly. | 22:05 |
katsmeow-afk | which way gets you longer ice crystals? | 22:05 |
katsmeow-afk | slow | 22:06 |
genehacker2 | that's what the cryoprotectants are fore | 22:06 |
katsmeow-afk | if you get a ton of *small* crystals, at least cell walls aren't perforated, and there's more open space betweenthem | 22:06 |
kanzure | genehacker2: again, the cryoprotectants are added to the bloodstream | 22:06 |
kanzure | they don't magically permeate throughout the entire body | 22:06 |
genehacker2 | In artificial cryopreservation, the solute must penetrate the cell membrane in order to achieve increased viscosity and depressed freezing temperature inside the cell. Sugars do not readily permeate through the membrane. Those solutes that do, such as dimethyl sulfoxide, a common cryoprotectant, are often toxic in high concentration. One of the difficult compromises faced in artificial cryopreservation is limiting the damage pro | 22:08 |
genehacker2 | http://en.wikipedia.org/wiki/Cryopreservation | 22:09 |
genehacker2 | now if we could find a way to vitrify tissue without that annoying cryoprotectant | 22:14 |
Phreedom | kanzure: http://www.bibconverter.net/ | 22:17 |
genehacker2 | now I wonder if one could put really a bunch of really tiny current loops in solution | 22:32 |
genehacker2 | and have the current loops tuned such that they emit radiofrequency when a current flows through them | 22:32 |
genehacker2 | if one could cool the solution with the current loops by placing them in a pulsed magnetic field | 22:33 |
katsmeow-afk | a strong enough dc magnetic field to dampen molecular vibrations? | 22:34 |
genehacker2 | the current loops would be so small they'd get jostled around by brownian motion | 22:34 |
genehacker2 | yeah | 22:34 |
genehacker2 | applying a magnetic field would generate a current in the moving current loops, which would emit radio waves, effectively cooling down a solution | 22:36 |
katsmeow-afk | i doubt it would respond fast enough | 22:38 |
genehacker2 | but would it cool stuff down? | 22:38 |
katsmeow-afk | and radio is ac, so a damping leading edge would be followed by a exiting trailing edge | 22:38 |
katsmeow-afk | exciting | 22:38 |
genehacker2 | what do you mean? | 22:38 |
katsmeow-afk | apparently not enough to be useful, sorry | 22:39 |
genehacker2 | well maybe not useful in small magnetic fields... | 22:39 |
genehacker2 | though the real question is could you put a really tiny magnet in a solution in proximity to a coil hook it up to a resistor in a box of the same temperature and violate the second law of thermodyanmics | 22:42 |
