--- Day changed Sat Sep 06 2008 | ||
pk | so what's new in transhumanism today? | 00:08 |
---|---|---|
pk | I saw Dean Kamen featured on the news with his "Luke hand", good to see that getting more press | 00:09 |
gene | it's not a neural interface | 00:10 |
fenn | it's not? | 00:10 |
gene | it's not anything like direct neural interfacing | 00:10 |
gene | it has balloons that provide feedback | 00:10 |
fenn | i thought they used the nerve stubs left in the chest (previously controlled the arm but now dead) | 00:10 |
gene | nope | 00:11 |
gene | it is also some control software | 00:12 |
pk | it's controlled by muscles further up the arm | 00:12 |
pk | iirc | 00:12 |
pk | there is an arm that's controllable via neural interface though | 00:14 |
gene | guess they got some sort of neuron interfacing going with it now | 00:14 |
fenn | apparently the luke arm is flexible enough to use several different input sources | 00:15 |
fenn | one of them is the nerve-stub-in-the-chest method; search for kuiken http://www.spectrum.ieee.org/print/5957 | 00:15 |
pk | I'm interested in Dean Kamen's ability to hyperfocus on one specific problem | 00:16 |
pk | and use the best in current technologies to address it | 00:16 |
gene | cool | 00:16 |
gene | there really needs to be a better way to interface with neurons | 00:16 |
fenn | i read a popular article yesterday about implanting chips into moth pupae, the moth brain then grows around the chip | 00:18 |
fenn | so.. how bout them SQUIDs | 00:19 |
pk | yeah I saw that before | 00:19 |
gene | Moths != human | 00:20 |
fenn | gene: i bet a human brain would grow around and interface with a chip implanted when it was an embryo | 00:21 |
gene | yeah, but then you might end up with developmental problems | 00:22 |
fenn | well shit, i've got eyeglasses and bad wisdom teeth, dont you consider that a developmental problem? | 00:22 |
pk | heh | 00:22 |
pk | well that would be an interesting experiment to try on mice | 00:22 |
fenn | wow SQUID can do NMR in a microtesla field | 00:26 |
gene | can squid see individual neurons? | 00:27 |
fenn | since it has extremely high temporal resolution, you could discriminate between separate firing events , but i cant think of a way to map that onto a particular neuron, because it has low spatial resolution (?) | 00:29 |
gene | dang | 00:30 |
fenn | maybe some way to do phased array sensing at high frequencies (small wavelength) | 00:30 |
fenn | but i dont even know the words to describe what i'm thinking | 00:30 |
fenn | anyway, the ability to do nmr in normal earth magnetic field gets you fMRI at least | 00:31 |
gene | you can do fMRI | 00:32 |
gene | using Earth's magnetic field? | 00:32 |
fenn | with a sensitive enough detector | 00:32 |
fenn | hmm one nice thing about vinge-style laser contacts is that you could read with your eyes closed | 00:34 |
gene | laser contacts | 00:35 |
gene | ? | 00:35 |
fenn | as seen in _Rainbows_End_ | 00:36 |
fenn | goes in your eye, connected to wearable computers, displays a virtual reality overlay | 00:36 |
fenn | squid is only one half of input/output | 00:37 |
gene | haven't read that one yet | 00:38 |
fenn | although... (and why hasnt anyone else said anyting about it?) you could use phased array microwaves as a highly selective rTMS-ish input device | 00:38 |
fenn | using the same superconducting coils as the microwave antennae | 00:39 |
fenn | or however squid works.. /me reads more | 00:39 |
gene | maybe one could make an mri contrasting agent | 00:40 |
gene | that responds to sodium gradients | 00:40 |
fenn | er... water? | 00:41 |
fenn | hydrogen is really useful for nmr/mri because it is so light | 00:42 |
gene | sodium is useful to look for because when neurons signal they do something with it | 00:43 |

fenn | graah | 00:50 |
fenn | why do i bother | 00:51 |
* fenn dumps some text anyway | 00:51 | |
fenn | The concentration of sodium in normal soft human tissues is 20-80 micromol/g wet weight, or about 1/1600th of the water hydrogen concentration which forms the basis of conventional magnetic resonance imaging (MRI). In addition, sodium's MRI sensitivity is only about 9 percent of hydrogen's. Despite these enormous handicaps, sodium imaging at clinical MRI field strengths of 1.5 Tesla with ~0.2 ml resolution is practical in ~15 min scan times or less. | 00:51 |

ybit | so what is the optimum overweight size and what is the correlation between krispy kreme donuts intake and intelligence? | 02:57 |
ybit | no debating if i should eat the last box of dozen donuts at the student organizations, it's for my brain | 02:58 |
ybit | or so i will rationalize :P | 02:58 |
fenn | wtf is 'excessive calorie intake' anyway | 03:07 |
fenn | calories have nothing to do with obesity | 03:08 |
fenn | its not like your brain is a diesel engine | 03:09 |
Phreedom | fenn: but drain does consume quite a lot of energy | 04:04 |
Phreedom | of course only if you actually use it | 04:04 |
Phreedom | *brain | 04:14 |
Phreedom | :) | 04:14 |
fenn | the scientists are making the assumption that only the energy expended while doing the 'hard thinking task' counts | 04:21 |
fenn | but really you would be thinking about it subconsciously at other times as well | 04:22 |
fenn | and you have to replenish neurotransmitters and remove waste products etc | 04:22 |

kanzure | Hey gene. | 16:24 |
kanzure | I just got back. Sorry about all that. | 16:24 |
Blobfish | Hey, nice to meet you! | 16:24 |
gene | hey | 16:24 |
Blobfish | Gene has told me quite a bit about you | 16:24 |
gene | about the biohacking toolkit and stuff | 16:24 |
kanzure | Ah, good. You like? | 16:24 |
* nsh would like to take this opportunity | 16:24 | |
Blobfish | haha, of course | 16:24 |
Blobfish | it's pretty awesome stuff | 16:25 |
kanzure | nsh: Hm? | 16:25 |
gene | Blobfish is also working on a repstrap | 16:25 |
nsh | to advise all present, with great emphasis, to search pubmed for the author John Mattick | 16:25 |
Blobfish | yeah, cutting some aluminum right now | 16:25 |
nsh | and read at least every abstract on the first page of results | 16:25 |
nsh | before you get all learn'd up with wrongness | 16:25 |
gene | huh? | 16:26 |
gene | Kanzure | 16:26 |
kanzure | Yes? | 16:26 |
gene | I talked to that guy about the polymerase yesterday | 16:26 |
kanzure | nsh: http://www.ncbi.nlm.nih.gov/sites/entrez?term=John%20Mattick&search=Find%20Articles&db=pmc&cmd=search | 16:26 |
kanzure | gene: Oh? | 16:27 |
kanzure | Blobfish: Do you know about closure engineering? | 16:27 |
nsh | this at a minimum: http://jeb.biologists.org/cgi/content/full/210/9/1526 | 16:27 |
gene | he doesn't think it's possible to do that sort of thing | 16:27 |
gene | for now | 16:27 |
nsh | kanzure: http://www.ncbi.nlm.nih.gov/sites/entrez?term=John%20Mattick&search=Find%20Articles&db=Pubmed&cmd=search | 16:28 |
gene | mainly because we really have much of an idea of how proteins fold | 16:28 |
nsh | (pmc is unfortunately still rather exclusive) | 16:28 |
Blobfish | fascinating | 16:28 |
gene | and not much in the way of computational power to simulate them | 16:28 |
kanzure | gene: We don't need to know how proteins fold. We just evolve the mutated polymerases to our liking. | 16:28 |
gene | how? | 16:29 |
nsh | kanzure, you mean brute force? | 16:29 |
kanzure | nsh: No, hold on. | 16:29 |
kanzure | http://heybryan.org/diagrams/retarded_polymerase.png | 16:29 |
gene | how do you measure the fitness of a polymerase like that? | 16:29 |
nsh | although | 16:30 |
gene | it's easy to measure the fittness of things like antibodies | 16:30 |
* nsh ponders | 16:30 | |
nsh | kanzure, 404 on that png | 16:30 |
kanzure | wtf | 16:30 |
kanzure | Is the server working at all? | 16:30 |
nsh | wait, no server | 16:31 |
gene | you just stick something covered in antigens in and see what sticks | 16:31 |
gene | so what is the deal about mattick | 16:31 |
kanzure | gene: You measure it by the length of the resultant strands and their relative brightness given some sort of fluorescent tag for certain nucleotides. | 16:31 |
kanzure | nsh: I did apache2 -k restart and I'm getting nothing. Any ideas? | 16:32 |

nsh | kanzure, server IP? | 16:32 |
kanzure | Blobfish: Yes. | 16:34 |
nsh | traceroute loses you the server at apogeenet.net | 16:34 |
Blobfish | rofl. are you hosting it from your dormroom? | 16:34 |
gene | Blobfish you should see his setup | 16:35 |
kanzure | nsh: Ah, yes, the IP has, in fact changed. | 16:35 |
kanzure | Blobfish: Hell yeah. | 16:35 |
Blobfish | haha, way to violate the terms of service! /me applauds | 16:35 |
kanzure | Blobfish: My setup is even more of a violation of TOS. | 16:35 |
Blobfish | kanzure: are you using dyndns for your domain name? | 16:36 |
nsh | new IP is whutpls? | 16:36 |
kanzure | Nah. I should use something like it. | 16:36 |
kanzure | nsh: fixing | 16:36 |
kanzure | http://66.112.232.136/ | 16:36 |
nsh | ty | 16:36 |
kanzure | Okay, heybryan.org and austinbrains.org should be working now. | 16:37 |
Blobfish | kanzure: heybryan.org works | 16:37 |
gene | btw | 16:38 |
gene | Kanzure, there's a programing contest today | 16:38 |
Blobfish | who here runs linux? | 16:40 |
Blobfish | or bsd? | 16:40 |
kanzure | gene: Where? | 16:41 |
kanzure | Blobfish: Linux for most of us. | 16:41 |
gene | Dang I forgot where | 16:41 |
gene | at about five | 16:41 |
gene | I think | 16:41 |
nsh | ARGH VISTA: HATE | 16:41 |
nsh | won't let me save changes to hosts file | 16:42 |
nsh | fucking retarded OS | 16:42 |
Blobfish | linux here too | 16:42 |
gene | it is | 16:42 |
gene | And I am running it | 16:42 |
* nsh only wishes | 16:42 | |
gene | I need to switch to linux | 16:42 |
Blobfish | i dual boot...but I haven't been in Vista for about 4 months | 16:43 |
gene | cool | 16:43 |
* nsh awaiting external to upgrade his laptop to "computer" status | 16:43 | |
Blobfish | I'm on a tablet PC, every time i upgrade the kernel I have to recompile the kernel modules for the active digitizer | 16:44 |
gene | So how much computational power do we all have here? | 16:44 |
nsh | apparantly, we have supercomputers | 16:44 |
Blobfish | hmmm...2.1 ghz with turion 64 x2 on laptop...dunno about the integrated GPU | 16:44 |
Blobfish | then my desktop has probably about the same...except with an 8600 gpu with half a gig of memory | 16:45 |
gene | do we have enough computational power to simulate proteins | 16:45 |
gene | lots of proteins | 16:45 |
kanzure | http://heybryan.org/mediawiki/index.php/Computational_chemistry | 16:45 |
kanzure | http://heybryan.org/mediawiki/index.php/Computational_biology | 16:45 |
kanzure | See for yourself. | 16:45 |
Blobfish | we might have enough to simulate lots of spaghetti... | 16:46 |
nsh | yay | 16:46 |
nsh | stupid fucking vista | 16:46 |
nsh | that | 16:46 |
nsh | 's 5 minutes of my life i'll never get back | 16:46 |
Blobfish | lol | 16:46 |

Blobfish | pangea...anyone? | 16:52 |
nsh | kanzure, my brain is dead from science overload, can you summarise this retarded polymerase idea in one or two pithy sentences pls | 16:52 |
nsh | i don't think we're allowed to make landings on europa | 16:52 |
nsh | i have a distinct memory of an exhortation to that effect | 16:52 |
kanzure | nsh: Laser-control of polymerase. | 16:52 |
nsh | controlling what? | 16:52 |
kanzure | Writes. | 16:53 |
nsh | start/stop? | 16:53 |
kanzure | And what to write. | 16:53 |
nsh | oh | 16:53 |
gene | why laser control? | 16:53 |
nsh | yaypipedreams :-) | 16:53 |
gene | why not LEDs | 16:53 |
kanzure | I have no special attachment to lasers. | 16:53 |
kanzure | LEDs would be great if they work. | 16:53 |
gene | cool | 16:54 |
gene | I think our best option for DNA synthesis might be that maskless lithography method using a DMD chip | 16:54 |
Blobfish | what about control by a laser on a shark's head? | 16:54 |
gene | heh | 16:55 |
kanzure | gene: The idea was that the polymerase would be self-replicable. | 16:55 |
gene | lasers aren't particulary self replicable | 16:55 |
kanzure | Build a fire. | 16:55 |
Blobfish | People are. | 16:55 |
kanzure | Also, organic LEDs exist. | 16:55 |
gene | guess they do | 16:55 |
Blobfish | does anyone else consider life an STD? | 16:56 |
gene | but the maskless lithography method might be faster an easier to accomplish | 16:56 |
kanzure | gene: It doesn't accomplish the goals though. | 16:56 |
kanzure | The point is the self-replicable and DNA synthetic aspects of it. DNA synthesizers, the type that we can go get in a lab, can otherwise be built. If that's your goal, go do that. | 16:57 |
gene | we still need to bootstrap the process | 16:57 |
kanzure | Purchasing metals isn't going to lead to bootstrappedness :-p. | 16:58 |
* kanzure gets started on his synthetic biology circuit creator thingy. | 16:58 | |
kanzure | Hm. The machine is locking up. | 16:59 |
gene | anyway I have been thinking about building a lego universal constructor | 16:59 |
kanzure | How is it going to make its own legos? | 16:59 |
gene | it doesn't | 16:59 |
gene | it assembles legos | 17:00 |
kanzure | Sigh. | 17:00 |
gene | this is phase A-B of the nasa self-replicating moon base study | 17:00 |
Blobfish | dang, i need more clamps | 17:00 |
kanzure | Not really. | 17:00 |
kanzure | This isn't the sort of thing you do ad-hoc. | 17:00 |
kanzure | In the study, Freitas clearly outlined closure engineering | 17:01 |
kanzure | which is, I dare say, not ad-hoc :) | 17:01 |
gene | phase A is build something that can build itself from it's own parts | 17:01 |
gene | phase B is have it build other things from parts | 17:01 |
kanzure | I don't think you understand, if you're not building the legos then you can't say it's constructing the legos. | 17:02 |
gene | phase C is have it build it's parts from raw materials | 17:02 |
gene | phase D is have it mine the raw materials | 17:02 |
gene | btw | 17:02 |
kanzure | That's a load of shit. | 17:02 |
kanzure | It's the same exact strategy that RepRap is using | 17:02 |
kanzure | And they don't do replication. | 17:02 |
Blobfish | Reprap can print shit now? | 17:03 |
gene | reprap can't assemble itself yet | 17:03 |
gene | it's not even on the scale | 17:03 |
kanzure | Yeah, but they like to lie about it. :-) | 17:03 |
kanzure | Like to the NY Times and so on. | 17:03 |
kanzure | Anyway, here's the thing: you're not going to be able to show that you have achieved self-replication from side-projects that aren't integrated with one another. | 17:04 |
gene | that's media overstatement | 17:04 |
kanzure | You've mentioned sandbots, claypit bots, lego bots, and all sorts of other constructors and assemblers, but none of them do the job. | 17:04 |
kanzure | No, that's them overstating i. | 17:04 |
kanzure | *it. | 17:04 |
gene | first off if you making a machine capable of assembling anything from parts | 17:05 |
kanzure | ? | 17:05 |
gene | it can assemble the machines necessary to make the parts | 17:05 |
gene | a machine made from nuts and bolts that can assemble itself | 17:06 |

kanzure | Have you been listening to fenn at all? | 17:06 |
* kanzure is wondering if we've made any progress at all here | 17:06 | |
kanzure | Also it's possible that I'm overcritical at the moment here. | 17:07 |
gene | yeah | 17:07 |
gene | the lego machine would demonstrate the assembly process | 17:07 |
gene | I am thinking of making a gantry crane made from legos that can assemble another working copy of itself from lego parts | 17:08 |
kanzure | But how do you show that you could integrate the fabricational complexity necessary to manufacture legos in the future? | 17:09 |
gene | this is a demonstrator | 17:09 |
gene | but kanzure | 17:10 |
gene | I have made a 3d printer out of legos | 17:10 |
gene | on the gantry crane thing | 17:10 |
gene | additional lego parts that don't exist in nature may have to be fabricated | 17:10 |
kanzure | I feel like I'm talking to a wall. Look: I am not disagreeing with you. Yes, you have indeed made a 3d printer out of legos and you indeed can make a 3D assembler out of legos, but you haven't shown me the evidence that randomly making up these designs necessiates the path towards a replicator. | 17:11 |
kanzure | nsh or fenn, how the hell did I explain it to either of you ? | 17:11 |
kanzure | ybit? | 17:11 |
gene | well the other option is to use something besides legos | 17:12 |
* Blobfish wishes he had a few more arms | 17:12 | |
* nsh too brainspazed to work out what is wanted of his memory | 17:13 | |
nsh | ask me on monday or something | 17:13 |
nsh | no wait, wednesday | 17:13 |
nsh | still conference on monday | 17:13 |
gene | like actually making a replicating gantry from steel or machined parts | 17:13 |
kanzure | The materials don't matter. | 17:15 |
kanzure | The design matters. You don't have evidence that randomly assembling parts together will result in "closure". That's what I'm talking about, and that's why skdb exists. | 17:16 |
gene | if you can assemble anything you will get closure | 17:18 |

kanzure | Not sure. | 17:24 |
gene | I have another idea about replication | 17:25 |
gene | do you know what electron beam melting is? | 17:25 |
gene | if you don't look it up | 17:26 |
gene | the basic idea is that an electron beam is used to fuse metal powder together | 17:26 |
gene | you use an electron beam melting machine to make it's casing and most of it's parts | 17:27 |
gene | and parts for the electron beam assembler | 17:28 |

kanzure | Nade, many of us hear have heard of NKS and have "agents" within the NKS realm. | 21:49 |
kanzure | However, I haven't actually read the book. | 21:49 |
kanzure | Blobfish: The name came about because of that 'roadmap' which makes little sense in retrospect. | 21:49 |
kanzure | Also, because people keep on coming in here. That's a good reason to keep the channel methinks. | 21:49 |
kanzure | There was a mailing list from 2007, but I haven't found a suitable relayhost since I got to the dorm in July. | 21:49 |
Nade | well you can read it for free online | 21:51 |
Nade | although i warn you, it's pretty big | 21:51 |
kanzure | It's safe to say that I know what it's about without having actually read Stephen's book. | 21:54 |
kanzure | And I somehow surround myself with people who have read it, or at least rant about it, so I think I'm in the clear [for the time being]. | 21:55 |
kanzure | Sunday, September 7th between 7am and 10am. <--- my server will be down | 21:57 |
Nade | well you should at least look at the pictures | 21:58 |
Nade | :p | 21:58 |
kanzure | Oh, I have. | 22:00 |
kanzure | I know what he's proposing too -- in general, a computational basis of reality, taken from the CA approach, if you read into it deeply enough. | 22:00 |
Nade | yep | 22:11 |
Nade | although I have to say I find the stuff about nature and diversity far more interesting.. | 22:11 |
