kanzurethese references are quickly getting me into the photography-PDF papers from the '60s00:00

joshcryerSo it seems to me most of you guys are focused on bioengineering.02:38
joshcryerRather than chemistry or electronics or software.02:38
Vedestinthere's a chemistry channel02:38
joshcryerRelated to replicatin or h+/02:38
Vedestinoh, no02:39
Vedestinthey're mostly drug addicts02:39
joshcryer#chemistry is general purpose... I don't think they'd like my ramblings much.02:39
joshcryerThough they'd understand more about how I think we could go about this.02:39
Vedestinwhat are you thinking?02:39
joshcryerHigh temperature compound seperation (recycling).02:40
joshcryerI'm converting those Thermodynamic Tables to Djvu format (because Adobe PDF is hopelessly slow).02:40
joshcryerIt's taken almost 24 hours.02:40
Vedestinahh02:41
Vedestinso what are you going to do? mine landfill?02:42
joshcryerYeah you could.02:46
joshcryerPart of the problem is breaking things down to their constituant parts.02:46
joshcryerNow I read some of the backlog and lot here seem to look to bioengineering for that.02:46
joshcryerBut that's an unknown field imvho.02:46
joshcryerWe already know how to melt stuff down and chemically seperate.02:46
joshcryerThe Thermodynamic Tables have every combination known to man.02:47
joshcryerThe other part of the problem is recombining those elements into something useful.02:47
facefacefacebut plastics don't melt nice02:47
joshcryerI think RepRap is doing OK in that vein so why not meet them halfway?02:47
facefacefacethere is no propper tm, cus they ... scorch? I forgot the precise term02:48
joshcryerPlastics don't normally biodegrade, either.02:48
joshcryerYou gotta engineer something that will eat them.02:48
facefacefaceword02:48
joshcryerEver hear about the Great Pacific Landfill?02:48
joshcryerA great amount of the worlds plastic winds up there.02:48
Vedestinthe ocean?02:48
joshcryerIt photodegrades.02:48
-!- facefaceface is now known as faceface02:48
joshcryerSo it will break down into smaller molocules.02:48
joshcryerBut what happens is the ocean currents put it in the north pacific.02:49
Vedestinso what is it, just a big island of floating shit02:49
joshcryerhttp://en.wikipedia.org/wiki/Great_Pacific_Garbage_Patch02:49
joshcryerYep.02:49
joshcryerValueable shit!02:49
joshcryer100 million tons of plastic and other garbage.02:50
Vedestinyeah, no i have heard of that02:51
Vedestinso what do you want to do? gather up discarded plastic, put it under heat and pressure and make it back in to useful shit?02:55
joshcryerYeah02:56
joshcryerBut not just that.02:56
joshcryerPlain soil has 10g of Ti, 90g of Al, etc.02:56
joshcryer(1000 grams of soil.)02:56
joshcryerSo it'd be great for recycling landfills but you could use it to make stuff out of plain dirt!02:57
faceface"crystalline melting temperature"03:00
facefaceThe boiling point of a polymer substance is never defined because polymers will decompose before reaching theoretical boiling temperatures.03:01
Vedestinthat's really more chemical engineering than transhumanism joshcryer03:02
joshcryerVedestin, you gotta start somewhere.03:03
joshcryerAdvanced production -> AI -> transhumanism.03:03
joshcryerimvho.03:03
joshcryerI came here cause kanzure said I might like it since you discuss replication.03:04
Vedestinyeah, fair point03:04
joshcryerThe discussion started with moon base replicators in #space. :)03:05
Vedestinmoon bases capable of building other moon bases?03:24
joshcryerYeah03:27

Vedestinit sure is interesting03:31
Vedestinbut yeah, they talk about boot strapping and that sort of thing in here03:31
Vedestini don't really know much about it03:31
Vedestinthey tell an analogy to me about some guy who built his own milling machine out of scrap metal and old broken shit03:31
joshcryerYeah03:34
joshcryerYou can do that.03:34
Vedestinyeah, i know03:34
joshcryerYou can make a forge that can melt metal that can be used to make a machine shop.03:34
joshcryerThat's basically classic bootstrapping right there.03:35
joshcryerThen you use the machine shop tools to make even more intricate stuff.03:35
Vedestinyeah03:35
facefaceto what extent is this idea of classic 'bootstrapping' analogous to a computer booting up?04:04
facefacedoes the analogy continue into the relm of developmental biology?04:05
facefacesend me your essays by next tuesday04:05
Vedestinisn't that why it's called booting up04:09
joshcryerConsider insemination and duplication.04:27
joshcryerThe rather classic example of biological bootstrapping.04:27

parodyoflanguageHello?15:22
parodyoflanguageAnyone active?15:25
fennsorta15:27
parodyoflanguageWell, hi then, to what is active.15:28
parodyoflanguageAnyway, I heard about this project from the extropy mailing list, and I've been on the hplusroadmap list.15:30
parodyoflanguageThough, there's a lot of stuff I'm not really understanding, but you guys are actually doing synthetic biology or just talking about it?15:30
parodyoflanguageI don't really know what the function/purpose of the programming you're doing is.15:33
parodyoflanguagehold on: found http://heybryan.org/mediawiki/index.php/Getting_up_to_speed15:34
parodyoflanguageAre there logs of this channel?15:35
fennno16:40
fennbryan is doing (or will be shortly) synthetic biology at U. Texas/Austin16:40
fennschool crushed any interest i might have had in genetic engineering16:40
fennso i'm now focused more on personal manufacturing16:41
parodyoflanguageah16:56
kanzure*ahem*18:15
* kanzure is sitting in the lab.18:15
kanzureso, I apologize for my lag18:15
kanzureit really is personal manufacturing, the trick is that it's all wetware and wetware sucks since it's not solid state18:16
kanzureparodyoflanguage: Yes, there are logs of the channel. 18:16
kanzureHowever, it's more of a need-to-know basis ... but last night I was uploading a partial log. http://heybryan.org/chats/2008-06-03_synthetic_biology_stuff_%23hplusroadmap.html18:17
kanzurefenn: so it turns out that not many enzymes are all that photosensitive18:24
kanzurehowever, I can't think of a 'go to next spot' signal that would be better than photons18:24
kanzureso if we can come up with, say, photo-activated rifampicin, which some papers have been saying specifically blocks stuff like RNA polymerase active site (where the magic happens), that would be great. by 'photo-activated' I mean 'make it into its pesky form, otherwise just sit there and do nothing special'. but it's sketchy.18:25

kanzureoh18:38
kanzureI bet polymerase knows what the other nucleotide is, via voltages18:39
kanzurethere's a distinct voltage for each nucleotide18:39
kanzurelast I checked, there are STM tips that are sharp enough to scan DNA18:39
kanzureso we can use these tips + quantum tunneling to test that18:39
kanzureif so, we can just make tips that run in synch with the polymerase molecules18:39
kanzurebut that's mixing solid state and wet ware :(18:39
fennAFM is not solid state19:08
fennand do you have any examples of actual DNA sequencing with STM/AFM?19:09

kanzurefenn: I just got a press release from RepRap saying it's able to make all of its parts22:05
kanzure'RepRap has, so far, been capable of making everyday plastic goods such as22:06
kanzuredoor handles,sandals and coat hooks. Now, the machine has also succeeded22:06
kanzurein copying all its own 3D-printed parts.   These parts have been printed'22:06
fennyay. it's about time22:06
kanzureso, if this is true, then I estimate 30 days until it's covering the planet22:10
Vedestin30 days22:21
Vedestinthat's not long at all22:21
Vedestinwhat can't it reproduce?22:21
kanzureitself22:22
PhreedomVedestin: almost everything22:24
Vedestinfair enough22:24
Phreedomplastic corners aren't very useful you know22:24
Phreedomand they didn't address generational degradation22:24
Vedestinno i guess not22:24
Phreedomso far (semi-)commerially manufatured reprap plastic parts were not printed by a reprap22:25
Vedestinso they're more durable?22:25
Phreedomand somewhat resemble the parts that are needed :)22:25
Vedestini see22:25
Phreedomif you take a closer look at reprap-made reprap parts, you'll see what I'm talking about22:26
kanzureargh22:26
Vedestinare the angles wrong?22:26
kanzurewhy the hell would they do that sort of a press release22:26
Phreedomrecently there were posted photos of quite high quality prints22:26
kanzure"WE DID IT! YAY AYAYAYAYAY! HUMANITY DAY"22:26
Phreedombut they were done using a better positioning system22:26
Phreedomor so it seems22:26
PhreedomI may be mistaken22:27
Phreedomso better see for yourself22:27
Phreedomof course reprap is progressing22:27
Phreedombut IMHO it's still not ready22:27
Vedestinnot ready to what?22:27
Phreedomnot ready to live up to its promise22:27
Phreedomlossless self-replication22:28
Vedestinoh22:28
Vedestini'm not sure what the point of it is beyond that22:28
Vedestinwhy would you bother making anything with it other than another reprap22:28
Phreedomthere's a hope reprap can be used to bootstrap other more useful manufacturing tehnologies22:28
Phreedomie their idea is spread reprap first and then make repraps around the world continuously upgrade themselves22:29
Vedestinso repraps will eventually be able to make circuits?22:29
Phreedombetter ask reprap devs ;)22:30
Vedestinseems kind of useless if it cant22:30
kanzureVedestin: exactly22:30
Phreedommy take on this is that it can be done eventually... but it's like reinventing the wheel22:30
Phreedomso I'm trying do go a more direct route22:31
Phreedomthat is produce a capable machine form the get go22:31
Phreedom*from22:31
Vedestinso it'll start with people getting a piece of pcb, reprap draws a circuit on and they etch it themselves or something22:31
Phreedommore or less22:31
Vedestinthen they've got to get IC and all that22:31
Phreedomof ourse22:31
Phreedomreprap guys did a good job with plastic extruders22:32
Phreedomtheir extruder head is quite usable already22:32
Phreedombut on a good cnc machine, not a reprap :(22:32

kanzureHey joshcryer.23:04
joshcryerSup23:05
kanzureCrying about #reprap.23:08
joshcryerThere's a #reprap?23:08
kanzureyes23:08
joshcryerOoh.23:08
joshcryerIt's bigger than here.23:08
kanzurejoshcryer: There was a press release today saying that RepRap self-replicates already. :(23:08
kanzureit implied it, at least.23:08
joshcryerkanzure, hah! HAH!23:08
joshcryerThey didn't imply it there's a friggin picture showing the clone. :)23:09
kanzuresorry, it didn't build itself -- a critical component of the design is the electronics23:15
joshcryerkanzure, I just know not three days ago you and nsh were saying that it couldn't even do what it was supposed to do (make the parts that it claimed to be able to make).23:16
kanzureno23:16
kanzureit's supposed to self-replicate23:16
kanzurethe claims from darwin are BS23:16
kanzuredarwin is not replicating and thus shouldn't be taking up the name 'RepRap'23:17
joshcryerNo.23:18
joshcryer1.0 was supposed to create much of the parts that consist of its design.23:18
joshcryerThe eventual goal is replication.23:18
joshcryerNot the first step.23:19
joshcryerWe've been over this twice man.23:19
fennthen they should say that in the press release hmm? somehow "replication achieved" doesnt quite convey the same information23:25
* fenn wonders if its worth reading #reprap backlog23:26
kanzurefenn: it's more of the same23:28
kanzurefenn: however, there's one interesting thing I have learned23:28
kanzurethey think it's "evolutionary" because of the *social* design process23:28
kanzurei.e., each person downloads it and they make an iterative hack on to the system23:28
kanzureand they say "look! it's evolving!"23:28
fennthey think it's "evolutionary" because it's named "darwin"23:28
kanzurebasically, "because everybody wants it to self-replicate, they will make it do that eventually"23:29
fenni.e. someone told them so23:29
Phreedomactually they'll make it eventually23:41
Phreedomthe question is when23:41
fennthere's no plan23:42
Phreedomyeah23:42
Phreedomno plan to address current known shortcomings23:42
Phreedom(without scapping the whole thing of course)23:42
kanzurescrapping?23:42
Phreedomthrowing away23:42
kanzureI think they hate me because what I suggest would require scrapping :(23:42
Phreedommaybe I'm not very good at english23:42
Phreedomactually while I think reprap is far away from *lossless* replication, i think the project is partially successful and definitely useful23:43
Phreedomthey made a good extruder head23:43
Phreedomand they managed to assemble community23:43
kanzureoh, it's successful, socially, it's useful, but it's not RepRap23:43
Phreedomso if a more practical project comes to replace reprap, there's some foundation to build on23:43
kanzurelike SKDB23:43
Phreedomkanzure: correct23:44
kanzure*ahem*23:44
kanzurethat's our whole point23:44
kanzurebut talking to you is like preaching to the choir23:44
kanzureyou're already doing similar work, right?23:44
Phreedomyes23:46
Phreedoma practical machine23:47
Phreedomwithout claims for self-replication, although it does make it's frame corners, metallic this time :)23:47
Phreedomand it can replicate frame corners losslessly23:48
kanzurefenn: interesting question-based approach23:49
kanzureforces them to answer something important23:49
fennor just ignore me23:50
Phreedomor play games till you take ball and go home23:50
kanzureit just hurts so badly though23:51
kanzurewhy would they make such a press release23:51
kanzurehow is that playing fair?23:51
Phreedomtruth sucks if you ignore it too much23:51
Phreedomkanzure: but they are hurting themselves23:51
Phreedomnot you23:51
