mcleodxHi Archels, this is the first time I've used IRC, just checking I'd connected properly04:57
archelseverything seems to be working04:58
archelswhat client are you using?04:58
mcleodxGood News, Freenode04:58
archelsno, that's the IRC network that you are connected to04:58
mcleodxOh the client, Limechat04:58
mcleodxIOS04:58
archelsalright, I don't know it04:58
archelslogs for this channel are in the topic by the way—if you were to use a shell account to connect you would always get backlogs of past conversation04:59
mcleodxNo worries seems good.04:59
archelskanzure: what did you mean by this? < kanzure> it doesn't make sense to directly work with your main processes05:00
mcleodx@archels I'd actually been directed here from a guy in a slack.com group for Transhumanism chat05:01
mcleodxI was looking for a group that are a bit more pragmatic in their approach to h+05:03
mcleodxThere's a lot of chat that happens there which is very random/trivial05:03

kanzurearchels: i mean that if you were a working software emulation of human brain matter, there's no reason to have a "single threaded" persona that is interacting with virtual environments. "location" isn't an entirely relevant concept (although caching and load times and processing times are relevant concepts).08:54
archelsyou're always going to be interacting with *some* simulated environment08:56
archelsI don't think it's such a clear-cut case08:56
archelsif I'm Bob's mindclone from 2 minutes ago, having solved some problem and having committed my results, maybe I wouldn't like to be terminated08:57
kanzureright, so about that.... "mindclones" are going to be computationally infeasible due to resource requirements at first. i mean, we are still taking multiple days to run simulations of a few microseconds of neural firing.08:58
kanzureall of this is going to be extremely resource constrained08:58
kanzurei also suspect there will be lots of competition for computing resources, probably going to the highest payers08:59
kanzureoops i shouldn't say "computationally infeasible" i should say "economically infeasible"09:00
kanzureeven with continued reductions in computing prices, i think that there is almost always going to be high demand to run certain more economically profitable algorithms.09:02
kanzurei'm not entirely convinced that people are going to spin up entire auditory cortex simulations to appreciate millions of hours of robo-mozart or whatever.09:02

maakukanzure: while you speak the truth, it is a hard sell. what do we appreciate in mozart in the first place? other than abstract respect, the enjoyment itself is a result of our inefficient, bizarre sensory apparatus09:34
maakuwe'll have to emulate those sense to appreciate historical human works of art, or to engage in the still-living subculture of retro art09:36
maakubut i'm sure that most people and artists wlil have moved on to using and appreciating less wasteful senses09:36
maakupeople will see that as losing humanity though, hence the hard sell09:37
maakukanzure: also I 100% support and encourage the MIT media lab harassment plan09:39

kanzuremaaku: they invited me under the pretense of bitcoin stuff but they seem OK with me using the opportunity to let fenn harass neil gershenfeld and ed boyden and the other nutjobs there09:45
nmz787_iis there a artificial general intelligence thing on the internet that I could ask something like: what is a unique descriptive word for each of the following wordlists [ohm, farad, volt] [kilo, mega, pico, nano]09:45
kanzureuh... wordnet? but it's not agi.09:45
nmz787_i(I called the former scientific units, the latter SI units... but I'm not sure that's right)09:45
nmz787_ihow does wordnet work?09:47
nmz787_iI searched kilo and it gave some uninteresting result09:47
nmz787_ioh, wrong search page09:48
kanzurewordnet works by converting thousands of hours of grad student life force into finely grinded pellets of language knowledge for general consumption09:48
maakunmz787_i: google had something similar http://googlesystem.blogspot.com/2011/08/google-sets-will-be-shut-down.html09:48
maakuthat's not an agi problem09:48
archelskanzure: I'm really glad to hear you say that, everyone seems to think that resources (and in particular, computation) will just come for free09:51
kanzureperhaps if emulation algorithm stuff turns out to be costless to implement....... but i see no evidence to believe tihs.09:51
kanzure*to run09:51
maakukanzure: it would be much less costly with quantum computaiton09:52
archelsapparently if you're running on a reversible computer, you cost almost no power to run09:53
maakuarchels: as long as you're not doing anything interesting09:53
archelsaren't reversible computers Turing complete though?09:55

archelshttps://www.weizmann.ac.il/complex/tlusty/courses/InfoInBio/Papers/Bennett1973.pdf09:56
archels"The biosynthesis of messenger RNA is discussed as a physical example of reversible computation."09:56
maakuarchels: memory isn't infintie. if you're doing anything adaptive or responsive to different environments then you need to be doing memory erasure, which is not reversible09:57
archelsit might tradeoff storage complexity for reversibility though09:57

kanzurenmz787_i: there's no way that "cloning and sequencing" is the bottleneck of dna synthesis :)10:59
kanzureanyway, having an alternative to yeast-based cloning is nice11:00
kanzure"Divide and Conquer (D&C), the quintessential recursive problem solving technique, is used in silico to divide the target DNA sequence to be constructed into fragments short enough to be synthesized by conventional oligo synthesis, albeit with errors (15); these oligos are synthesized and are recursively combined in vitro, forming target DNA molecules with roughly the same error rate as the source oligos; error-free parts of these ...11:00
kanzure... molecules identified by cloning and sequencing are extracted and used as new, typically longer and more accurate inputs to another iteration of the recursive synthesis procedure"11:01
kanzureso... they are just using traditional oligonucleotide synthesis. yawn.11:01
kanzurei'm not convinced that biologists know what a bottleneck is supposed to be :)11:01
nmz787_iah, hmm, thanks... when the abstract didn't sound interesting, and scanning briefly didn't yield anything seemingly interesting... I had my doubts there was anything interesting there11:13
nmz787_i(especially because I am thinking about coding stuff at the moment)11:13

nmz787_ihmm, so the small cells are about 200nm diameter... so 100nm radius... plugging that into volume of sphere, I get 4.19 million cubic nanometers14:59

nmz787_ii guess you could start peel a nanometer or two from the cell diameter, if you assume the membrane is 1nm thick15:01

High-quality surgical preparation of mice takes ~1 h, and each autopatching experiment can be carried out over periods lasting several hours. Autopatching should enable in vivo intracellular investigations to be accessible by a substantial number of neuroscience laboratories, and it enables labs that are already doing in vivo patch clamping to scale up their efforts by ...18:42

kanzure"The standard unsupervised recurrent neural network language model (RNNLM) generates sentences one word at a time and does not work from an explicit global distributed sentence representation. In this work, we present an RNN-based variational autoencoder language model that incorporates distributed latent representations of entire sentences. This factorization allows it to explicitly model holistic properties of sentences such as style, ...19:19
kanzure... topic, and high-level syntactic features. Samples from the prior over these sentence representations remarkably produce diverse and well-formed sentences through simple deterministic decoding. By examining paths through this latent space, we are able to generate coherent novel sentences that interpolate between known sentences. We present techniques for solving the difficult learning problem presented by this model, demonstrate ...19:19
