genehackerfigure out what this has to do with portable oxygen concentrators and my evil plan.00:24
genehackerstratasys makes biocompatible plastic00:26
genehackerhmmmm00:26
kanzuregenehacker: did you see the paper on water-curable polymers?00:36
genehackerno00:37
genehackerdo link00:37
kanzurewell foo.00:37
kanzureoops, sorry00:37
kanzurewater-soluble polymer00:37
kanzurehttp://heybryan.org/books/papers/parviz/Water-soluble%20sacrificial%20layers%20for%20surface%20micromachining.pdf00:37
genehackerTHAT'S EVEN MORE INTERESTING!00:39
kanzureother papers by the same author: http://heybryan.org/books/papers/parviz/?C=S;O=D00:41
kanzurethis one was neat: Drosophila as an unconventional substrate for microfabrication00:42
kanzurePhoto-patternable gelatin as protection layers in low-temperature surface micromachinings00:42
genehackercan you squirt it out of an extruder?00:43
genehackerwill hot plastic stick to it?00:43
kanzure"Interestingly, gelatin can be used as a binder in light-sensitive photlithographic products. Adding dichromate into gelatin makes it a photo-patternable material like negative photo-resist."00:44
kanzure(UV light)00:44
kanzure*photolithographic products00:45
genehackerinteresting00:46
kanzureas in, gummy bears00:46
genehackerlet's find a way to grow it in tanks00:46
genehackeredible? bet it's not00:46
kanzuresadly, the gelatin material is not the same thing as the water-soluble polymer voodoo magic00:46
genehackerthough I did see this weird chromium compound in this one drink?00:46
genehacker;(00:47
kanzurehrm. dichromate shouldn't be too hard to acquire.00:47

kanzure-any28973518: namcub is enki203:30
kanzure-he's in #namcub on this server03:30
kanzure-he uses /stories/ebooks/ for his xsublim system .. which I'm still not convinced is doing anything productive for him.03:31
any28973518what's a xsublim?03:33
any28973518i feel stupid going to thatroom just to ask that, but i will, i swear!03:34
-!- any28973518 is now known as katsmeow03:35
kanzure-xsublim is a subliminal messaging system for X1103:35
katsmeowobviously, that's not the home automation line carrier thing?03:35
kanzure-no. :(03:36
kanzure-that's X1003:36
kanzure-X11 is the linux window server thingy03:36
katsmeowo03:37
katsmeowno one there03:38
kanzure-elias`: where is namcub?03:38
katsmeowwell, ENKI-][ is online with ZaLGOS in #discord on another net, but that's as close as i can get, because s/he's afk and the bot seems to be off03:57
kanzure-hrm. okay. I'll hunt him down in a bit if you want.03:57
kanzure-he should be in #wrongplanet03:58
katsmeowan aspie, eh?03:58
kanzure-you're surrounded by them03:58
katsmeowoh no!03:58
* kanzure- flails arms as if a ninja03:58
* katsmeow looks scared03:59
katsmeowi was in #wp yesterday, i had to let off some steam04:00
genehackerzalgo?04:14
katsmeowwhat's that?04:15
genehackeroh good you're not 'one of them'04:15

ybiti like it04:19
ybitsadly though, it hasn't been recognizing forms correctly, so i'm resorting to wget to login and retrieve files from sciencedirect04:20
kanzure-would it be more interesting to do "recursive self amplification" than "recursive self improvement" ?04:25
kanzure-(considering the definitional problems re: improvement)04:25
genehackerthey're both the same04:32

katsmeow-afkSouth Korean scientists claim that they have created the world's first cloned, glowing dogs at Seoul National University.18:15
katsmeow-afkThe Korean experts said Tuesday that they engineered four beagles that glow red18:15
katsmeow-afkWed, 29 Apr 2009 09:26:12 GMT18:15
katsmeow-afkThe four dogs, all named "Ruppy" - a combination of the words "ruby" and "puppy" - look like typical beagles by daylight.18:15
katsmeow-afkthey hope they can use the same techniques to make non-glowing dogs too18:16
fenncrime against nature, those poor ruppies, etc etc18:21
fenni can just see the jokes about glowing dog-burgers already18:22
katsmeow-afkDrinking water containing considerable amounts of an element known as lithium can help reduce the rate of suicide, a Japanese study finds. 18:22
katsmeow-afk i bet the more paranoid, who think the gov is putting things in the tap water, kill themselves in record numbers18:22
kanzureFrank Harold replied to my email. yay for old scientists having enough time to answer email.18:23
fennso, you can buy GE aquarium fish, how is that possible? what regulatory framework is there for selling them as pets?18:23
kanzureSeoul National University is a scary place.18:23
kanzurethey have Suh.18:24
kanzurehttp://heybryan.org/books/papers/microfluidics/suh/18:24
fennkatsmeow-afk: lithium helps with bipolar disorder18:24
fenn...not paranoia18:24
katsmeow-afkthat's why i said the paranoid would be killing themselves in greater numbers18:24
kanzurewhat's the point of paranoia if you're just going to kill yourself18:25
kanzureisn't the point to avoid thingies that would kill you?18:25
fennperzackely18:25
katsmeow-afkno, it's to avoid pain and loss of control18:25
kanzuremaybe I've been doing the paranoia-thing all wrong18:25
fennbeing dead is pretty much 'loss of control' in my book18:25
kanzureI am interested in this book and wish to subscribe to your newsletter.18:26
katsmeow-afkit's like :  German-based company SolarWorld AG has invested $500 million on a site in Hillsboro, Oregon <<== but i am not allowed to put up the 10 pv panels i bought in 200118:26
fennyou'll have to contact my agent18:26
kanzureso I emailed Frank for a good reason- I don't know if any of you read his article or the notes I was taking on it18:27
kanzurehttp://heybryan.org/books/papers/to-shape-a-cell_notes.txt18:27
kanzurewas asking him about good high-throughput morphogenesis experiments18:27
kanzureinstead of traveling the world looking for diverse phenotypes of microorganisms, I was wondering if I could just use an evolution-acceleration-chip-thingy to put the selective pressure on diverse phenotypes, or something18:28
kanzureshape isn't exactly specifically genetically controlled, so just adding a DNA synthesizer on a chip isn't going to make wonderful things happen18:28
fennit's hard to select for diversity18:28
* kanzure nods18:28
kanzurebut billions of different droplets surely come in handy18:29
kanzureI would consider tagging the cell walls with some marker, and then coming up with a way to make sure a cell isn't "cheating the system"18:29
fennwhy interested in cell shape?18:29
kanzureand then do some optics, record the shape of the cells in a droplet, and do something based on that18:29
kanzurenot sure18:29
kanzuresomething to stare at18:29
fennmost cells are either 'blob' or some kind of repetetive self assembly result18:30
kanzurehttp://heybryan.org/books/papers/bacterial_shape.png18:31
fennwow that's e. coli?18:31
fennpenicillin interferes with cell wall construction18:32
kanzuregenes that might be interesting: http://heybryan.org/books/papers/morphogenesis_mutations.png18:32
fennpenicillin interferes with peptidoglycan crosslinking, so presumably that mutant doesn't do any crosslinking18:34
kanzureanother worthy diagram: http://heybryan.org/books/papers/selective_value_of_bacterial_shape.png18:35
fenncaulobacter is a neat one to study18:36
kanzureon a more meta note, it is interesting to know that since shape is not explicitly defined in the genes,18:37
kanzureall of the taxonomists have been applying a selective pressure for different specimens in different categories18:38
kanzureon a more meta note, it is interesting to know that since shape is not explicitly defined in the genes,18:38
kanzureall of the taxonomists have been applying a selective pressure for different specimens in different categories18:38
kanzurewhich has, no doubt, influenced selective pressures involved in taking specimens between labs, or something18:39
fenn_actually most bacteria look like little balls or little sticks18:39
-!- fenn_ is now known as fenn18:39
kanzuremaking yourself look like something more interesting surely has an advantage18:39
fennnot for a microbe18:40
kanzurein a lab?18:40
fennthe number of microbes in labs is tiny compared to the rest of the world18:40
kanzureyeah I know18:40
kanzurebut I was talking about selective pressures in labs18:40
kanzurebecause of taxonomists18:40
fennlast estimate i heard was that only one in a million wild type strains could actually be cultured18:40
fennthere's a bacterium (single cell) that you can actually see with naked eye, it lives in the intestine of tuna? salmon?18:41
fennnobody's been able to culture it, regardless how much fish guts they throw at it :P18:42
fennkanzure: did you know your mediawiki install is borked?18:43
kanzureyes. :(18:43
fennok18:43
kanzurenobody has yelled at me loudly enough to fix it18:43
kanzurewhy are you guys using it anyway18:43
* fenn shrugs18:43
kanzuredoes it have anything useful?18:43
fenni wanted to back-up the skdb and sand/silicon replicator texts before it blew up18:44
kanzureok. I'll fix.18:44
kanzureUnable to lock ibdata1, error: 11. Check that you do not already have another mysqld process using the same InnoDB data or log files. 18:45
kanzureblah, i don't.18:45
kanzureah, 'mysqlcheck' is my friend now.18:49
-!- any36617078 is now known as katsmeow-afk19:04
kanzureok, wiki fixed19:08
fenn_i dont suppose i ever posted the .dia file for that19:14
fenn_for the terrible skdb diagram19:14
-!- fenn_ is now known as fenn19:14
kanzuresomewhere on fennetic.net19:14
fennall i have are early revisions19:15
fennoh well19:15
kanzurewait, isn't the .dia file in the wiki page? I installed the mediawiki-graphviz extension..19:16
fennno19:17
fenndia isn't graphviz anyway19:17
kanzuredunno whether it's good or bad that campbell and I both came up with similar data structures re: skdb-related-stuff. the "control point" class that I was writing, and his "functional parameter" class.19:21
kanzurehm.19:26
* any59249990 got nice tornado pics 19:56

fennhow do i automatedly chop out a section of a multi line file?20:01
fennsed seems to only want to work with one line at a time20:01
kanzureyour question is confusing20:01
kanzureline 1 line 2 line 3 line 4 and you want to cut out specifically lines 2 through 4?20:02
fenni'm trying to download wiki html and extract the form contents on the edit page20:02
kanzureew20:02
fennyeah20:02
kanzurewtf is wrong with you20:02
fenni hate sql?20:02
kanzurehttp://heybryan.org/mediawiki/index.php/Special:ViewXML20:02
fennum, so?20:02
kanzureor use pywikipediabot20:03
kanzurehttp://pywikipediabot.sourceforge.net/20:03
fenndammit i just want one page20:03
fennwell, all revisions of one page20:03
* fenn kicks the frozen corpse of sed20:04
kanzureyou could use perl's HTML::Parser tool20:04
fennit has nothing to do with html20:04
kanzure"form contents on the edit page"20:04
fennit's multiline regex20:04
kanzureisn't there a way to do $^ or something?20:04
fenngrep -Eo 'textarea\(.*\)textarea' ought to work20:04
kanzuresomething like $^$ should get you a blank line20:04
kanzureoh20:05
-!- any09683000 is now known as katsmeow-afk20:05
kanzureisn't that an issue of greedy versus non-greedy or something20:05
kanzureI'm not being of much help.20:05
* kanzure hangs up his regex-foo nunchucks.20:06
fennhm20:07
fennRHEL come with pcregrep installed, which does Perl-compatible regex matching. And by adding a -M switch you get multiline matching!20:07
fenndamn swiss army knife salesmen20:08
fennsilly me to expect pcregrep to behave like grep20:10
-!- any97824977 is now known as katsmeow-afk20:11
kanzureoh20:19
kanzuremaybe the bond graph people were cheating by making anything "through" to be "division" and anything "across" to be multiplied20:20
kanzureand thus how they assembled their symbolic equations?20:20
fennlike R = V/I20:20
fenn?20:20
kanzureyes20:22
-!- any76888520 is now known as katsmeow-afk20:24
-!- any20062887 is now known as katsmeow-afk20:30
fennnow even python is letting me down20:32
fennmaybe its time to give up and go to sleep20:33
fennhttp://pastebin.ca/141151720:34
fennfor some reason it finds the first 'textarea' but not the second20:34
kanzure-is it escape quoted20:34
fenneh?20:35
kanzure-the second one is </textarea>, which I guess doesn't matter20:35
-!- any67958940 is now known as katsmeow-afk20:37
kanzure-fenn: try printing out each time 'textarea' is found and see if it finds it20:37
kanzure-*finds both20:37
fenner.20:38
fenni dont know how to do that20:38
kanzure-while line != 'eof' .. line = f.next() print line .. blah blah blah20:38
fennwhile True: if f.next().find('textarea'): print line ?20:38
kanzure-ok, close enough20:38
fennoh. hm20:39
fennmaybe it's all on one line20:39
kanzure-how could that be? 20:40
kanzure-it displays as multiple lines in the browser20:40
kanzure-without <br> elements20:40
fennok it's not all on one line20:40
fennabove code snippet just dumps the entire file20:40
fennoh duh20:41
kanzure-what is line20:41
fennfind is annoying and returns 1 or -1 instead of True/None like you expect20:41
kanzure-(in that one-liner)20:41
fenni couldnt figure out how to do it in one line so meh20:41
fennline = f.next()20:41
fennline.find('textarea') doesn't show the second one20:42
fennif line.find('textarea') >= 1:20:43
kanzure-ok, try the basic myfile = open(blah), while myfile: line = myfile.readline(); if line.find. ..20:45
fennall right i figured it out20:45
kanzure-what was it20:45
fennfind is just stupid20:45
fennfind returns the index of the substring blah blah blah20:45
fennso it's not always 120:45
fenni started out using contains() but i guess that doesn't work for strings20:46
-!- any12058110 is now known as katsmeow-afk20:46
kanzure-I think that's arrays/lists.20:46
genehackerso how terraformable is ganymeade20:47
kanzure-ganymeade?20:47
kanzure-is that your grandma?20:47
genehackerganymeade20:47
genehackermoon of jupiter20:47
kanzure-hm.20:47
genehackercurrentyl has a think oxygen atmosphere20:47
genehackerhaven't you watched cowboy bebop?20:47
kanzure-if I tell you that I've only seen three episodes, will you kill me? :(20:48
genehackerno20:48
genehackerthat's fine20:49
genehackerI haven't seen any of gundam yet so...20:49
genehackerin bebop ganymeade's been terraformed and is covered in ocean20:50
genehackerdoubt that could be done as ganymeade is pretty far from the sun20:52
kanzure-meh. giant mirror reflection network thingies.20:53
genehacker???20:53
genehackerof course20:53
genehackercovered in water ice, oxygen atmosphere20:54
kanzure-so, genehacker, here's what I've been thinking of for ADL20:54
genehackerOXYGEN ATMOSPHERE?20:54
genehackerbad!20:54
genehackerfor life20:54
kanzure-you know how you have to do various calculations to figure out whether or not some machine or scenario is feasible20:54
genehackerok20:54
kanzure-for instance, the other day I was doing some calculations for waterjet cutters in microfluidic devices20:55
kanzure-and campbell was doing something like pneumatically powered bicycles20:55
kanzure-anyway, 20:55
kanzure-it would be nice to write some software that would make it easier to do those sorts of calculations20:55
kanzure-instead of saying "I NEED A GEAR!", you'd say something like20:55
kanzure-"I NEED A HOOKE's LAW!"20:55
kanzure-er, I mean, "I NEED A SPRING" (not a GEAR)20:55
genehackerpneumatic bicycles? got a link on that20:55
fenncowboy bebop isnt the most realistic show ever20:56
genehackerindeed fenn20:56
kanzure-http://epicycle.org/2006/06/air-power.html20:56
genehackerno I have a link on pneumatocycles20:56
fennthere's a difference between a back of the napkin feasibility calc and a detailed simulation20:57
kanzure-pneumatocycles, haha20:57
kanzure-fenn, I agree20:57
kanzure-but I still think the same substrate for feasibility calcs can be dumped into finite-element method solvers20:58
genehackerpn3umatic transmission bikes20:58
fennunits works pretty well for napkin calcs20:58
genehackerhttp://www.act.sys.okayama-u.ac.jp/kouseigaku/research/goto_bike/english.htm21:00
genehackersystem error21:02
fennthese people all seem to be ignoring the fact that pneumatics are an inherently inefficient method of transmitting power21:11
genehacker85%21:11
genehackerso yeah21:12
genehackergears are near 10021:12
genehackerI think21:12
kanzure-genehacker: do you know of a book or index of simple machines and the simple equations that describe them? especially for some obscure machines.21:18
fennchain is 98.5%21:18
genehackeryes21:18
genehackerwhat was that called a gain21:18
genehackerX mechanical movements21:18
genehackerLOW POWER21:19
genehackerit's in the reprap blog21:19
fenn1800 mechanical movements?21:20
genehackeryes21:20
kanzure-was that from cmu.edu ?21:21
genehackersome reprap guy freed it I think21:22
genehackerUgh21:22
fenni dont see any laws of motion, just a picture and short description21:22
genehackercan barely move21:22
genehackerwell I'm out21:29
kanzure-hi cis-action 22:29
kanzure-oh22:38
kanzure-I guess it should be possible to consider cell development/growth with magnetic particles or something22:39
kanzure-to stretch the cell in a certain direction by manipulating the magnetic field or rotating the cell.22:39
kanzure-we need a mole in whitesides' group22:53
ybitseems the sleeptracker has been improved23:46
kanzure-the what?23:46
ybithttp://www.sleeptracker.com/features.html23:46
ybiti had the standard about 4 years ago and sent it back23:47
ybitmight try out a new one23:47
ybitwakes you up when you aren't in deep sleep and now records sleep data23:47
ybitmy biggest complaint was that it didn't have a snooze button and also the alarm wasn't loud enough. they have fixed the alarm sound by making it louder and adding the vibrating option, not sure about the snoozing23:49
* ybit is sending an enquiry to find out atm23:49
