drazakI wonder how hard it is to synthesize my own00:00
kanzure_Yay00:01
kanzure_http://heybryan.org/mediawiki/index.php/DNA_synthesizer00:01
kanzure_Check the oligonucleotide synthesis instructions.00:01
drazakoh hey00:01
willPow3ri synthesized one with your mom last night00:01
drazakI think I'm going to build my own thermocycler00:01
kanzure_How exactly?00:01
kanzure_I've never understood the rapid cooling mechanisms.00:01
drazakwelll00:02
kanzure_Was this some sort of thermal piezo material ?00:02
kanzure_voltage=>rapid cool down methodology?00:02
drazakwhat I was thinking is instead of using convectiona and radtiation, I'd have a small water heater, and 2 servos to open the gates for a drain and for cooling00:03
kanzure_And what would the physical flow setup look like? a tube sitting next to a pvc pipe with the water flow, or you manually moving the tube from hot to cold water bins?00:05
drazakand put the reagents+thermometer in a mostly covered whatchamacallit (the small plastic 'test tubes' for centrifuges)00:05
drazakno no00:05
drazakno manual moving00:05
drazakI want to be able to walk away00:05
drazakok, so I have a bin of water00:05
drazakand the ends of the tubes sticking in, the bin of water has an in tube and an out tube, and also a heater00:05
kanzure_What sort of gate do you plan on using? I suppose you could use a metal plate attached to a sturdy pin that rotates like a rotating door. 00:06
* kanzure_ is assuming noncontinuous flow, which probably isn't a good idea.00:07
drazakthe heater brings the tubes up the the first temperature, for denaturation, then to cool it, both servos flip, opening the water gates, water flows in until the thermometer hits the temperature for annealing00:07
drazaktimer times, heater comes on for extension temperature, and then repeat 30-40 times00:08
drazakthe whole process00:08
drazakthen it goes to final extension and hold00:08
drazakand we're done00:08
drazakhook it up to either a computer or a programed atmel chip to execute the program00:11
kanzure_I suppose what you really need to do is confirm that the temperatures you hit will do what you think it's doing.00:11
drazaknah00:12
drazakit's well documented00:12
drazakthe temperatures, that is00:12
drazakthere's a few things that change00:12
drazakbut that's simple to change00:12
kanzure_No, I mean your system.00:12
drazakoh00:12
kanzure_confirmation of functionality and such.00:12
drazakyeah00:12
drazakwhich is why you have a therister in one of the tubes, measuring the temperature of the reagents00:12
drazakso that you can ignore specific heat00:13
kanzure_fenn: How does the AA heat the water in the $10 thermocycler? 00:15
drazakhm00:15
drazakyou know00:15
drazakit would be simpler to simple turn on 2 water pumps00:16
drazakthan fuck with servos00:16
drazakyou can get cheap water pumps for like $2-5 each00:16
kanzure_is that so?00:16
drazakyeah00:16
drazakreally small ones00:16
drazakbut you don't need very big00:16
kanzure_if you can price out a system for less than $10, I can hook you up with a manufacturing deal00:16
drazakwell00:16
drazakit's going to be ~1500:17
drazakoff the top of my head00:17
* kanzure_ waves hand in crude attempt at Jedi mind trick, "You want to price it out for under $10."00:17
drazakyou could do it with cheap paint trays00:17
drazakyeah yeah00:17
kanzure_right00:17
drazakI'm just thinking of how to do it cheaper00:17
drazakso you need 3 paint trays00:17
drazakso there's like 3-4 bucks00:18
drazakI guess you could do it with one water pump00:18
drazakso call it 2 bucks00:18
drazakthe water heaters the only expensive thing00:18
drazakI was thinking one for fish tanks00:18
drazakwhich is like 10-1500:18
kanzure_what's so special about this heater?00:19
drazakdunno00:19
drazakthinking about that more00:19
drazakthat's a bad idea00:19
drazakbecause you'd have to rewire it so that it goes hotter00:19
kanzure_Hrm. I used to blow shit up all the time when soldering. Stuff would heat up without warning.00:27
kanzure_Find a high emissivity resistor to wire up to a battery, hook that into a slightly larger test tube and submerge the other tube within that one as well.00:27
kanzure_Water is still good, though maybe not the water heater ;-)00:28
drazakheh, I know how to solder rather well00:32
drazakI design and build my own headphone amps00:32
kanzureIt's not a matter of soldering well :-) but rather doing dangerous things with what you're soldering.00:35
drazaknahh00:35
drazaknot if you hit it fast00:35
drazakthere's a technique behind soldering stuff like that00:35
kanzureNo, it's not the soldering that does the Dangerous Thing, it's what you're soldering together that blows up when you turn it on or whatever.00:36
drazakoh, that00:36
drazak:P00:36
drazakthanks knowing electronics00:36
drazak:D00:36
kanzureHrm?00:36
drazakanyway00:37
drazakit looks like the cheapest water pump online is like 10$00:37
drazakI swear I bought some for like 3 or 4 though00:37
fennthe idaho thermocycler i used the crap out of was just a fan and a lightbulb (and a microcontroller)00:39
drazakhm00:39
fennit's the fastest design, because instead of microcentrifuge tubes you use glass capillary tubing, so it has a large surface area to volume ratio00:39
drazakwell00:40
drazakwater+water heater is faster00:40
drazakget a heater and turn up the power, and you'll be doing good00:40
fenni think you're wrong about that00:40
fennwater heats by conduction, whereas a lightbulb can heat by IR radiation00:41
fennthe pcr mix had a blue dye in it, which might have absorbed IR but i think it was just so you could see what you're doing00:41
drazakyeah00:42
drazakthe blue dye is actually to help with the gel00:42
drazakbecause it's nto a dye at all00:42
drazakit's bromophenol blue00:43
drazakwhich is a loading buffer00:43
drazakbasically when you're doing the gelling, it moves at the same speed as the dna so that you can see when it's done00:44
fennbtw domestic water heaters have this valve that prevents it from getting hot enough for pcr00:44
drazakoh, that's not the type of heater I was talking about00:45
fennok00:45
drazakI meant like a fishtank heater00:45
fenni like the lightbulb+fan idea00:46
fenntwenty seconds on, twenty off, vroom vroom vroom00:46
drazakeh00:47
drazakI guess00:47
drazakI'd use one of those special bulbs though00:47
drazakor like a 100W bulb00:47
fenn100W is special?00:47
drazakor00:47
drazak:D00:47
drazakbut they make special bulbs for heating stuff00:48
fennoh, sure00:48
fennyou can get 130V "commercial service" bulbs too, which glow a little dimmer00:48
fennmore IR in the spectrum00:48
fennnot that it matters i guess, since all the light gets converted to heat eventually00:48
drazakwhat microprocessor?00:52
drazakI can't think of any you can buy for that cheap00:52
kanzurePICs are ridiculously cheap00:54
drazakare they?00:54
kanzurebuck fifty?00:54
drazakI don't like the PICs as much as the atmel ones00:54
drazakavr's00:54
kanzurewell sure .. but those are going to cost more.00:54
* drazak opens his tin of parts00:55
drazakhmm00:55
drazakI see like 5 or 6 avrs00:56
kanzurescrew it00:56
kanzurejust hook it up to LTP00:56
drazakyeah00:56
drazakI was thinking about that00:56
kanzure_or RS23200:56
kanzureor RS232.00:56
kanzure_shut up.00:56
drazakI can't program though, so regardless, someone else is going to have to help me write the program00:56
drazak:P00:56
kanzure_Highly dependent on how friendly your inputs are to the machine. Does the thermometer have a clear protocol for spitting back the current temperature? etc.00:57
drazakif you use a thermistor00:58
kanzure_if it's wired to an LCD, then the answer is yes, and just remove the LCD and wire it into your boxen00:58
drazakyou can just use an a/d converter00:58
kanzure_?00:58
kanzure_analog to digital converter on /what/ ?00:58
drazaka thermistor00:58
kanzure_How does this work?00:58
kanzure_surely you don't mean an analog read out to digital ?00:58
drazaka thermistor is basically a resistor that changes resistance based on temperature00:59
kanzure_oh. nevermind.00:59
drazak:P00:59
kanzure_Somebody's sending me storage for a few dumps of my collections.01:13
kanzure_I'm planning on first sending it somewhere else. Who wants?01:14
drazakyour music? no thanks01:15
kanzure_It's not music.01:15
kanzure_I'm fairly confident that I have a highly desirable collection over here.01:16
drazakporno?01:16
kanzure_nature01:16
drazakoh :P01:16
fennatmel AVR's are $0.50-$1501:55
fennlast time i looked at least01:55
fennthe $2 ones will do just about anything you can ask of a microcontroller01:56
fennPIC gets a reputation for being cheap because their company will send free samples to anybody no questions asked01:57
fennhow big is nature?01:58
kanzure_40 GB but it seems I'm missing some things. For instance, I didn't have that Raman paper.01:58
fennookina yu-ni-va-su01:58
kanzure_?01:58
drazakkanzure_: what's in nature?01:59
kanzure_the majority of nature01:59
kanzure_I have an 8 MB index if you want to see it02:00
drazakdo you have any sort of access to published papers/whatnot?02:00
drazakthat I could use02:00
kanzure_ha ha ha02:00
kanzure_yessir02:00
drazak:D02:01
drazakthat'd be awesome02:01
fennwill probably hate this: http://fennetic.net/pub/irc/coppe_8_monologue.mp302:01
* kanzure_ has been listening to Carlos Santana - Europa for the past I don't know how long02:01
kanzure_http://heybryan.org/papersdir_list.txt warning, this is about 8 MB.02:02
drazakhow big is the directory with the actual papers?02:02
fennhow many papers?02:03
kanzure_122,000 papers02:03
kanzure_checking with du -h.02:03
drazakkanzure_: du -ckhs is more efficient, fyi02:04
kanzure_hm. Maybe I meant to upload full_index.txt02:04
fenndu -k and du -h cancel, -k wins?02:05
fennand -c -s doesnt make sense either02:05
drazakuh02:05
drazakfenn: k doesn't do what you think it does02:06
drazak:D02:06
fennk reports number of 1k blocks02:06
fennwhich screws up -h02:06
drazakwrong!02:06
drazakwell02:06
drazakright02:06
fennenlighten me then, O master of vudu02:06
drazakbut h takes preference02:06
drazakhm02:06
drazakusing an outdated command02:06
fenndu -chks02:07
fenn9828    .02:07
fenn9828    total02:07
drazakthat's how you'd do it for coreutils like 9 versions ago02:07
drazaklulz02:07
drazaknot on my system02:07
drazakdrazak@localhost ~/My Music/NIN $ du -ckhs02:07
drazak2.2G    .02:07
drazak2.2G    total02:07
kanzure_130+ GB of music if that counts. Still running.02:07
drazakregardless though, if you want to know how big a directory is, du -ckhs is better, it doesn't print/try to print to standard out if you have a whole bunch of papers02:08
kanzure_Still going.02:11
kanzure_It's not listing files yet either.02:11
kanzure_Had I been smarter I would have preserved some directory structure to the rip.02:12
fennlike volume, issue?02:13
kanzure_yes02:13
fennwhat are the filenames like?02:13
kanzure_title of the paper02:14
drazakkanzure_: I was hoping some sort of university login or something02:14
kanzure_drazak: You want me to give you logins? Sorry, I don't do ezproxy trading rings any more .. I tried to trace them to the source once, but that failed.02:15
drazaknot what I meant02:15
fenn"00 million pledged to support ex-Soviet science" how generous02:15
drazakbut ok!02:15
fennthere's gotta be some way to "slice" huge datasets into different file systems without duplicating the data02:17
kanzure_'file systems', split 40 GB into ext2 and ext3 ?02:17
fenni mean so you can have a big dir full of every paper, and also sorted by volume/issue, and also by field or whatever02:18
fennand not have to use some crappy SQL server to do it02:18
kanzure_something better than virtual links?02:18
fennlinks would work i guess02:18
drazakkanzure_: why would you split it into ext2 and 3?02:19
drazakthe only difference is journaling02:19
kanzure_trying to understand fenn.02:19
drazakand ext3 generalyl speaking gives better performance02:19
kanzure_he said 'file system'02:19
kanzure_so I thought 'file systems'.02:19
drazakoh :P02:19
fenni meant directory structure02:19
fenni was thinking "02:19
fennproc filesystem02:19
drazaklol02:20
fennwhy is that funny?02:20
fennnevermind, trying to explain why something is funny is an exercise in futility02:20
drazakaye02:23
fennkurzweil has this music generator program that responds to biofeedback02:25
fennit would be neat to do that with a chatroom02:25
kanzure_streaming audio server?02:25
fennoften i want to beam music phrases at people but 1) english sucks at that and 2) you'd disrupt whatever the other person was listening to or just the mood in their head02:26
kanzure_recently I was thinking of a program that would generate european dance music mixes02:26
kanzure_it's fairly algorithmic to get a beat going, plus plays on samples taken from a library of various snippits of classic songs02:26
fennas much as i like euro trance i think that's an awful idea02:26
kanzure_heh02:26
fennsort of like a markov bot, but with music02:27
kanzure_sir, are you saying I'm a bad idea?02:27
fennit's entertaining for about ten minutes02:27
kanzure_people have called me a markov bot before.02:27
kanzure_aw.02:27
fennnothing personal :)02:27
fennits just sometimes you show an extreme lack of physical groundedness02:27
fennlike the recent discussion on openmanufacturing02:28
drazakaye02:28
kanzure_arguably I'm more grounded02:28
drazakwellll02:28
kanzure_note how I've been talking about interfacing with B2B for the material procurement issues02:28
drazakas much as it's ac ool idea, I think that most of the hplus research can't be done in an opensource enviroment02:28
kanzure_you get your direct realization of materials from bits and bytes, what's not to love about that ?02:28
drazaknto easily, atleast02:29
kanzure_drazak: eh?02:29
fenni think he was talking about more of an autonomous ground-up scheme02:29
kanzure_explain?02:29
kanzure_fenn: patrick?02:29
fennrather than trying to interface with businesses etc, just make what you need to spec02:29
fennyeah02:29
kanzure_fenn: I don't know why he doesn't call that a design.02:29
drazakkanzure_: well, most of the research takes a lot of money to do it 'right'02:29
kanzure_"it's not a design! it's reality! rawr"02:29
drazakand if we're not going to do it right, we may as well not do it at all02:29
kanzure_drazak: Do what, now?02:30
fennbecause his vision is exceedingly low-tech and based on tested designs mostly, and he has no idea how to actually implement it (business plan stuff)02:30
fennit's easy to come up with a business plan when you have a technological advantage, but not so easy when you're digging in the dirt like a medieval subsistence farmer02:30
drazakkanzure_: research bioengineering of the human race in a way that could be applied large scale02:30
kanzure_is that your understanding of what we've been talking about, drazak?02:31
fennand so i'm sort of amazed my friend just got a $100k loan to dig in the dirt in bumfuck pennsylvania02:31
drazakkanzure_: well, there's more to it02:31
kanzure_fenn:  building a house?02:31
fennfarming02:31
drazakbut imo to do the research, you may as well do it right, and I'm all for finding out a way to come up with a low cost solution02:31
kanzure_solution to what?02:32
drazaksolution to research tools02:32
kanzure_You're being vague :-)02:32
drazakaye02:32
fenn'solution to research tools' wtf does that mean02:32
fennlike "how to do PCR without paying invitrogen $50/pop"?02:33
kanzure_fenn: but he was talking about overall goals and projects,02:33
kanzure_so I'm wondering what he thinks those are02:33
drazaksolution to lack of research tools/supplies02:33
kanzure_human race engineering or whatever seems like a peculiar answer02:33
kanzure_it's not a wrong answer, just something I wanted to poke at02:33
drazakit's part of the impression I got from the biohack site02:34
fennin the history of science, there was no supplier that magically created analytical tools out of thin air02:34
fennpeople had to come up with their own designs and build them with what they had02:34
fennnow we just have a big patent snarl02:35
drazakfenn: aye, but most of the tools needed for research in molecular biology and whatnot have already been made02:35
drazakthey're just expensive02:35
fenntime to move to guptastan I say02:35
kanzure_drazak: yes, a big part of Things in general is bootstrapping tools.02:35
fenni find it odd that smari is whining about people bringing in unidentified plastic, but nobody is working on fablab-DIY chemical analysis tools02:38
fennwhat the heck do they make in these fablabs if not better fablab tools?02:38
kanzure_in the cities and the US, I don't know02:38
kanzure_but supposedly Gershenfeld has these in third world countries02:39
drazakkanzure_: I get the impression that transhumanism is about making humans and therefor humanity better02:39
kanzure_and theoretically they're making 'useful stuff' ?02:39
fennuseful stuff is like, radio transponders for sheep, or milk dilution testers02:39
kanzure_drazak: btw, you can ignore the title of the channel. that's leftovers because everybody keeps showing up here. 02:39
kanzure_drazak: but yes, that'd be nice.02:39
fenngershenfeld goes on and on about "the analytical divide" but its in his own labs if you ask me02:40
drazakthen what is the general goal of the channel02:40
fennthe same goal of every channel02:40
fenn... to try and take over the world!02:40
fennit's true, dont try to deny it02:41
willPow3r_dan dennett is so jittery when he speaks02:41
willPow3r_its hard to follow what he says sometimes02:41
kanzure_It would be interesting but pointless to say the goal is improvement. 02:42
drazakaye02:42
kanzure_I'm not sure we can prescribe a goal02:42
fennbased on the channel name i think the idea is to come up with a way to get to various types of improved states of being02:44
fennway/ways02:44
fennfor instance, i want to see in radio to x-ray spectrum02:44
drazakno thanks02:45
fennso that's part of why i'm obsessed with wearables02:45
kanzure_I'm not sure if we can go by the channel name any more. 02:45
fennkanzure_: too "mission oriented" for you?02:45
fennat least we arent talking about taxes or communism02:46
drazakI'm trying to come up with a goal for my own research02:46
drazakthat's acheivable in ~6 months02:46
fenncome up with a goal that's not achievable in 6 months02:46
fennthen try to do something related02:47
fennyou might even get tenure if you repeat that enough times02:47
drazakheh02:47
* fenn sulks02:47
drazakyou do know I'm 15, yeah?02:47
drazaks/15/1602:47
kanzure_too old.02:47
fenndon't pigeonhole yourself02:47
fennthe only reason young people don't play a more active role in society is they get sent to sensory-deprivation prisons for 15 years02:48
drazakfenn: this is why I'm trying to teach myself a whole bunch of stuff :)02:48
drazakI worked my way through ochem 1 and 2 recently02:48
drazaklearning biochemistry atm02:48
kanzure_fenn: so, yes, it does sound almost too mission oriented.02:49
kanzure_recall the issues in recursive self-improvement.02:49
fennkanzure_: do you not believe in the concept of "improvement" now?02:50
kanzure_people still trying to figure out how to quantify improvement02:50
fennwe can very easily quantify some types of improvement02:50
fennheck there's even a world happiness index02:50
kanzure_I could possibly go for some computational optimization big o notation arguments on certain types of improvements. 02:50
fenn0 cpu cycles is the best kind of algorithm02:51
fenn(translation: people do a lot of useless crap)02:51
kanzure_O'Neill habitats, or even O'Neill habitats without the "in space" aspect, is where it's at -- it's not a platform necessarily for improvement, but if improvement or beneficial mutation does occur, it can be harnessed and repeated.02:51
fennluf is all about the ocean habitats, and the more i think about it the more i realize that the moon would be a lot easier to colonize02:52
kanzure_fenn: easier than the ocean?02:52
fenn(if only we had a rotovator)02:52
generotovator?02:52
fennwell, two rotovators, one for earth and one for luna02:52
geneoh yeah02:52
geneI remember now02:52
fennmomentum exchange tethers02:53
geneyou might be able to dig a hole in the moon if you get your lunar rotovator just right02:53
fenni think the objective is to not crash into the moon :)02:53
genebut if you but a shovel on one end ans spin it fast enough...02:54
fennjust fill plastic bags with the loose dust that's everywhere on luna02:54
geneyup02:54
fennthen the tether comes down and picks up the bag02:54
geneand sell it on earth as genuine moon dust!02:54
fennhah, sell it in orbit as genuine space colony materials02:55
genethat too02:55
fennor use it to re-boost your earth rotovator02:55
geneyeah02:55
geneor shoot it at the earth's atmosphere for a continuous fireworks show02:56
fennmost people dont realize that lava tubes are kilometers in diameter on luna02:57
geneKILOMETERS?02:57
fennyep02:57
geneyou're kidding02:57
genedamn02:57
fennlow gravity02:57
genegreat place to build a house02:57
fennyou can see some collapsed tubes, um, hadley rille maybe is one of them?02:59
kanzure_fenn: so, back on topic02:59
kanzure_where were we.02:59
kanzure_were we making me declare a goal or something?02:59
drazakmaybe03:00
drazak:D03:00
fenni think you were trying to clear out the cruft accumulating in the topic03:00
kanzure_in the /topic ?03:00
genegoal03:01
geneto make a self-replicating automaton03:01
bkeroI'll tubes your topic.03:01
kanzure_gene: That's not the meta-goal.03:01
kanzure_gene: The kinematic self-replicating machine work is a subset of some others.03:01
geneplease specify meta goal03:02
kanzure_fenn: feel free to moderate the /topic I guess.03:02
kanzure_Everyone has known my own personal goals for a while now .. that simple "to do as much as possible" phrase.03:03
genespecify goal03:03
geneto make a replicator validator program?03:03
fennself replicating machines are useful for effectively eliminating most economic costs03:03
fennbut then what to do with them?03:03
kanzure_fenn: That's not the way that we stumbled upon them.03:04
genewhat do you mean what to do with them03:04
fenni want to build giant structures in space to communicate with the zodiac, but i dont expect anyone else to share that goal03:04
genesolve world hunger, make dyson spheres, make cheesecakes the size of cities03:04
fennyes, cheesecakes, the size of cities03:04
kanzure_The reason why I refuse to specify goals so clearly any more is because of my previous involvement in that goal cult.03:05
fennkanzure_: it's the way i stumbled upon them03:05
fennkanzure_: have you seen the price tag on a new lathe?03:05
kanzure_fenn: In our discussions in here, specifically, we started from talk about things other than replicators, and then arrived at replicators. That's what I meant.03:05
kanzure_Wait. Maybe not. /me doesn't know his history.03:06
fennhm the new lathe argument doesn't work so well with all the cheap tools from china now available03:06
kanzure_Argument for what?03:06
fennbut they used to be like $800003:06
fennso it was worth taking the time to build one from scratch03:06
fennand then i realized that there was just all this stuff laying around, and you just had to put it together right03:06
fennbut the lathe is mostly self-generating, so how far could you stretch that concept03:07
kanzure_fenn: I seem to recall us moving to talks about replicators after talk about 'improvement'.03:07
gene_what the heck just happened03:07
fenni seem to recall you found me because of the gingery machines wiki03:07
fennor something like that03:08
kanzure_hrm, that's right.03:08
kanzure_So maybe it was just replicators from the go. Huh.03:08
fennanyway, i was working on airmuscles for an exoskeleton or some such03:08
fennso it's not like i was just pimping my chevy03:08
drazakhm03:10
kanzure_drazak: This was recent and might point to a few things: http://heybryan.org/bootstrapping_personal_fabrication.html03:11
kanzure_I sent an email to Michel once that talked about 'supply chain length minimization' (I am program, programmer and that which is programmed)03:12
kanzure_That phrase has relations to http://heybryan.org/recursion.html 'course. 03:13
drazakhm03:15
drazakI need to learn more about synthesizing primers03:15
kanzure_http://heybryan.org/fractal.html was a partial elaboration about springboarding via philanthropical bootstrapping to get to stable points of functionality in large scale systems (like, say, O'Neill habitats, or civilizations in the sense that Kevin Kelly talks about re: civilizations-as-an-organism)03:15
kanzure_drazak: http://primerfox.com/03:16
drazakI wonder if there's a way eventually to synthesize bacteria to make commonly used primers03:16
kanzure_http://heybryan.org/mediawiki/index.php/DNA_synthesizer for oligonucleotide synthesis instructions03:16
gene_FURRY ALERT03:16
kanzure_drazak: Yes, there is. 03:16
kanzure_drazak: Consider wrapping the primers in the plasmid or bacterial genome with endonuclease recognition sites.03:16
kanzure_And then just have bacteria that manufacture the endonucleases, and purify those.03:17
gene_what's a primer?03:17
kanzure_That's the idea of http://heybryan.org/new_exp.html the do-it-yourself bioreactor project.03:17
drazaknot wha I was thinkig at all03:17
drazakhold on03:17
kanzure_gene_: http://en.wikipedia.org/wiki/Polymerase_chain_reaction PCR requires primers so that polymerase knows where to start replicating.03:17
drazaklet me grabthe word03:17
kanzure_s/replicating/copying/03:18
fennoh my god, your nick is "gene" and you dont know what a primer is?03:18
gene_I thought primers were the nucleotides not the sequence you want to copy03:18
drazakahh, plasmid is the word03:18
drazakyeah03:18
drazakkanzure_: plasmids would definitely be a way to do it, I'd think03:19
* fenn is cranky, must be time for bed03:19
kanzure_Sure, but you still need to have a supply of endonucleases.03:19
kanzure_fenn: but we're not done03:19
drazakkanzure_: are plasmids replicated in bacterial cell division?03:19
kanzure_drazak: Sort of. I recall that they 'drop off'. They are not multimeiosis-cyclic-stable. 03:20
kanzure_Erm.03:20
drazakhm03:20
kanzure_fenn etc - are you guys really going to hold me for a 'goal' ?03:20
drazakthat's a flawed way to do it then03:20
fenni like google's "dont be evil"03:21
fennbut that's not a goal03:22
kanzure_whatta about my energy useage maximization principle? 03:22
kanzure_"Do as much as possible with as little as possible, until I can do everything with nothing at all"03:22
fennwhy would you want to use energy?03:22
fennright03:22
gene_I think you mean minimization03:22
kanzure_No, I do not mean minimization.03:22
kanzure_No point in being idle.03:22
gene_ok03:22
gene_I see what you mean03:22
fennbucky fuller called this technological growth process 'ephemeralization'03:23

fennthe word extropy is too bound up in philosophy03:23
fenncell phones are generally not considered "extropic" are they?03:24
genewhoa03:24
kanzure_I don't know about that generally, but I would consider them extropic, yes. 03:24
genesomething weird is going on03:24
fennyour connection is flaky03:25
geneI keep losing my connection to the irc server03:25
geneor my kinematic modellor could be messing it up03:25
kanzure_Lots of relations to the constructal theory too -- the points of suboptimization are construed to the nodes in the system, i.e. cell phone users, see how much they hate their interfaces (little keys, not a lot of memory, and yet ..). <- I'm screwing this up a bit, but I'm too lazy to figure out how at the moment.03:25
kanzure_Something about natural systems organizing such that all of the choices that you'd rather not make are made by the individual agents, i.e. an individual router ends up having to choose where to send packets to instead of global routing protocols.03:26
kanzure_Anyway.03:26

genejust do it03:26
genedamn03:27
genekinematic modeller isn't liking my geometry at all03:27
drazakkanzure_: I meant for making my own primers chemically03:28
drazakkanzure_: as in building the sequence03:28
kanzure_Yes, that's nucleotide synthesis via oligonucleotide synthesis.03:28
kanzure_Oh, do you mean to start with pre-made dNTPs?03:29
drazakno03:29
genewhat about the nucleotides?03:29
fennstart with nitrogen, oxygen, carbon, phorphorus, hydrogen?03:29
drazakfenn: not... really03:30
fennor maybe just a big ball of undifferentiated energy03:30
drazakfenn: synthesis of nucleotide chains03:30
kanzure_I'm pretty sure the oligonucleotide synthesis stuff works for that, drazak.03:30
drazakok03:30
drazakyep, didn't know it was a different word03:31
drazak:)03:31
fennstandard oligo stuff is only good for 25-50bp; how do they do those 3kbp sequences?03:31
kanzure_ligation?03:31
geneDeinococcus radiotolerans DNA repair complex?03:32
geneuse sticky ends?03:32
fennbut you'd have the same error rate, unless they somehow amplified single strands and checked each one03:32
kanzure_I doubt they check.03:32
fennit's not damaged dna, you just get the wrong sequence03:32
genethat's what the Deinococcus radiotolerans DNA repair complex does03:33
fennthey'd have to check, otherwise they'd have the same error rate as if they just made a big oligo from scratch03:33
geneit puts two sticky ends together03:33
geneif some of the nucleotides don't match then it replaces them03:33
fenngene: this is single strand synthesis03:33
kanzure_gene: That's not what we're talking about.03:33
kanzure_http://mrgene.com/03:34
kanzure_http://e-oligos.com/03:34
geneyeah03:34
fennthere is no other strand to check against03:34
genebut you can synth a bunch of small strands such that they all overlap03:34
geneand then have the repair complex check em03:34
geneventer's doing it03:34
kanzure_The repair complex checks complementary strands.03:35
geneto compile his organisms03:35
kanzure_There is no complementary strand here.03:35
fenngene: do you have a link explaining this process?03:35

geneI meant to say deinococcus radiodurans03:36
fennthat's how i read it anyway03:36

kanzure_gene: On Monday I can give you a linux disc.03:37
genegood03:37
genevista has pissed me off03:37
geneso deinococcus checks it genome against multiple copies03:38
kanzure_Yes, so that's definitely not what we're talking about.03:38
genethen what are you talking about single strand synthesis?03:39
fenni can see how this would work, since you get to 'vote' on the correct nucleotide03:40
geneyeah03:40
geneI think it's sorta like that03:40
geneI haven't read many radioresistance papers in a while03:41
fenni guess i should just watch venter's ted talk instead of fighting with google03:41
genenah03:41
geneI don't think venter says much about it in the ted talk either03:41
geneI believe he just puts the dna in deinococcus03:42
geneor something like that03:42
fennwell here's a protocol, doesnt really answer my questions: http://books.google.com/books?id=8x02velGjKMC&pg=PA374&lpg=PA374&dq=overlapping+oligo+synthesis&source=web&ots=dCVC6hCYB8&sig=jY18FQL4BEE-VCKtFtQn3wCm2H8&hl=en&sa=X&oi=book_result&resnum=5&ct=result03:43
fenn'screening isolates by cloning and sequencing' is basically what i meant by having to check each oligo03:44
kanzure_right03:44
fenn450 is much better than 50 03:45
geneso how do we synth enough to make a protein03:49
genelike a fancy polymerase03:49

fennchicken and egg problem03:50
geneyou've read The Diamond Age haven't you fenn03:50
fennyep, but i had the idea first :P03:50

drazakhey, the ligands interacting with signal receptors and ion channels on cells are not the organometallic ligands, right?21:32
fenn"the organometallic ligands"?21:32
fennorganometallic just means it has a metal ion stuck to it, but those are usually used for metabolism/catabolism21:33
drazakright, but those are different ligands, right?21:33
drazakbut when you talk abotu organometallic interactions, you talk about ligands21:34
fenni suppose21:34
fennproteins can interact with metal ions too21:34
drazakright21:35
drazakbut:21:35
fennum, here's an example: EDTA is an organometallic ligand if it picks up some metal ion21:35
drazak"Cells also have surgace membrane proteins (signal receptors) that present highly specific binding sites for extracellular signall moleculse (receptor ligands). When an external ligand bonds to its specific receptor, the receptor protein transduces teh signal carried by the ligand into an intracellular message.21:36
fennoh, that just means the molecule that binds to the signal receptor21:37
