yoleaux | Self-organizing genetic codes and the emergence of digital life - Pargellis - 2003 - Complexity - Wiley Online Library | 07:26 |
kanzure | "The emergence of self-replicating programs from an initially disordered “prebiotic” phase consisting of randomly generated opcodes (virtual machine instructions) is a challenging problem. The computer world, Amoeba, has many virtual CPUs acting upon sequences of randomly generated codons (opcode templates). An assignment matrix degenerately maps these codons to a genetic basis set of opcodes, analogous to the translation of ... | 07:26 |
kanzure | ... nucleotides to amino acids. Amoeba self-organizes by increasing assignment probabilities for those codon-opcode pairs in successfully generated children. This halves the effective size of the opcode basis set, doubling the rate of emergence over the control case (random assignments)." | 07:26 |

kanzure | "Pargellis found that on average, a self-replicating sequence of instructions would spontaneously arise after about 400 generations. Initially, such 'self-reps' were often unnecessarily complex, and contained portions of code which performed no useful task, or were skipped over." | 07:33 |

kanzure | "Those disembodied lungs are amazing. And incredibly creepy. The business plan -- patching up donor lungs not approved for transplant (which is most of them) and keeping them alive long enough to find a patient they can save... to the tune of perhaps 2,000 lungs and lives per year. That's pretty amazing. Approved in Canada and awaiting FDA approval as well?" | 08:50 |

kanzure | "On a Virginia farm, she’s also raising genetically altered pigs, in the hope that someday their lungs (and other organs) will be modified for use in human transplant, creating a nearly inexhaustible supply of organ donors." | 08:50 |
kanzure | "The process is legal in Canada, and Rothblatt’s company is among a few trying to win FDA approval. It has worked on more than 40 lungs since May, practicing and documenting results.

kanzure | "At $20,000 net sales per transplant, this is a projected $60 billion market. Recently published results demonstrated that pancreatic islet cells from Revivicor pigs, when transplanted into diabetic monkeys, cured diabetes for over 1 year with complete normalization of blood glucose levels (van der Windt et al., 2009). The pigs used in these studies were engineered such that a human gene (“CD46”) was added, and a key pig gene ... | 08:53 |

narwh4l | oh hey there turtle | 13:51 |
kanzure | turtle butt | 13:51 |
narwh4l | turtle camwhore | 13:51 |
kanzure | maybe there was an rna replicator ecosystem prior to cells | 13:52 |
kanzure | er, food web | 13:53 |
poppingtonic | that was huge | 14:00 |
fenn | it's called the "RNA world hypothesis" | 14:00 |
kanzure | rna world hypothesis does *not* specify an ecosystem | 14:01 |
fenn | are you sure | 14:02 |
kanzure | "It may, therefore, have played a major step in the evolution of cellular life.[7] The RNA world would have eventually been replaced by the DNA, RNA and protein world of today, likely through an intermediate stage of ribonucleoprotein enzymes such as the ribosome and ribozymes, since proteins large enough to self-fold and have useful activities would only have come about after RNA was available to catalyze peptide ligation or amino acid ... | 14:04 |
kanzure | ... polymerization.[8] DNA is thought to have taken over the role of data storage due to its increased stability, while proteins, through a greater variety of monomers (amino acids), replaced RNA's role in specialized biocatalysis." | 14:04 |
poppingtonic | rna doesn't require *that* much energy... | 14:04 |
kanzure | i don't know if any of that counts as an ecosystem | 14:04 |
kanzure | i agree that rna doesn't require lots of energy, but you don't just go rna self-replicators -> cellular membranes | 14:04 |
fenn | so if RNA #1 eats RNA #2 it doesn't count as a "food web"? | 14:05 |
delinquentme | hey python comes default installed on macs right? | 14:07 |
kanzure | cannibalism sort of counts, but i am not sure you can bootstrap cells from only cannibalism | 14:07 |
fenn | cells has nothing to do with this particular question | 14:07 |
fenn | i guess it's some terrible philosophical "identity" problem | 14:08 |
poppingtonic | what would an ecology of rna molecules do? If there's free energy (maybe sunlight or geothermal energy), and a heat bath, and RNA (but no DNA), what's missing from the picture? | 14:08 |
poppingtonic | delinquentme: i think it's ruby. | 14:08 |
fenn | scarce resources; RNA molecules that replicate the most win because they're more likely to survive $calamity | 14:08 |
kanzure | in the case of computer simulations, who knows-- usually the ecosystem collapses and dies off | 14:08 |
kanzure | without the "emergence" of other forms of life | 14:09 |
poppingtonic | I've seen guns and spaceships designed using GoL elements in Golly. | 14:11 |
fenn | there are other ways to contain molecules besides lipid membranes | 14:11 |
poppingtonic | Gosper gliders and other elements. | 14:11 |
poppingtonic | they can get pretty complex, but the fundamental ops are simple automata. | 14:12 |
fenn | you could make a net of carbohydrates and stuff your food in there, or hide in a crevice on an inorganic surface | 14:12 |
fenn | or both | 14:12 |
fenn | poppingtonic: most of those were created (engineered) by humans | 14:12 |
fenn | kinda defeats the purpose | 14:12 |
kanzure | none of those methods seem to be usable in a simulation of string-based code-based lifeforms | 14:12 |
kanzure | "where" would the surface go | 14:13 |
poppingtonic | fair enough. | 14:13 |
fenn | RNA is a string-based lifeform :P | 14:13 |
kanzure | yes but there's a spatial dimension as well | 14:13 |
kanzure | it doesn't have magical memory access to other rna molecules | 14:13 |
fenn | is it possible for a "code" life form to concentrate resources? | 14:14 |
-!- pete4242 [~smuxi@boole.london.hackspace.org.uk] has quit [Remote host closed the connection] | 14:14 | |
kanzure | instead it has magical physical access to other rna molecules, heh | 14:14 |
kanzure | maybe, but there would have to be an idea for how that would look | 14:14 |
kanzure | probably something like "different code has different resource binding affinities" | 14:14 |
kanzure | and then... the binding has to look like something... | 14:14 |
fenn | what if you had something like proof of work | 14:15 |
kanzure | ? | 14:15 |
fenn | or did i just send you into a feverish schizophrenic fit where you'll ramble about the simulation argument and the universe being a cryptocurrency miner | 14:15 |
kanzure | no you're thinking of chaitin | 14:16 |
fenn | uh. so the only scarce resources in a code simulation are: cpu cycles, randomness, memory | 14:16 |
kanzure | your simulation can introduce other scarce resources that bundle those together | 14:17 |
fenn | most of these alife toys feed the system randomness at some low level or it will be terribly boring | 14:17 |
kanzure | and it's not really "cpu cycles" but rather "simulation cycles" or something | 14:17 |
kanzure | *simulation ticks | 14:17 |
fenn | right so proof of work is a way of packaging up cpu cycles in a bit string | 14:18 |
fenn | but in order for it to mean anything, the selection function has to favor it somehow | 14:18 |
kanzure | there's certainly a way to favor valid proof of work | 14:18 |
fenn | yeah you just only evaluate code that has a valid proof of work attached to it | 14:19 |
fenn | once a code string figures out how to make a proof of work string, it counts as self replicating | 14:20 |
kanzure | huh? | 14:20 |
kanzure | so the way that these simulations worked was randomly seeding the memory with random opcodes, then executing code | 14:21 |
fenn | like a transcription factor; the simulation reads strings of bits and only starts executing if the bit string hashes to 0x00whatever | 14:21 |
kanzure | and eventually self-replicating programs were found in this mess | 14:21 |
kanzure | i don't think you need to start with proof-of-work-favoring? | 14:21 |
fenn | i dont see how you would ever develop an ecosystem/food web when everything is equally distributed | 14:22 |
kanzure | go on? | 14:23 |
fenn | self replicators sure, but they wouldn't *do* anything | 14:23 |
kanzure | apparently they even infect each other, create copies, have different strategies | 14:23 |
poppingtonic | does rna process information at all? | 14:24 |
kanzure | i was working on transcriptional logic gates a long time ago, hehe | 14:24 |
fenn | poppingtonic: it copies strings of RNA... | 14:25 |
kanzure | arguably, rna stores information | 14:25 |
kanzure | no, indisputably | 14:25 |
fenn | no, arguably! | 14:25 |
* fenn argues | 14:25 | |
kanzure | perhaps there could be a scarcity of bits | 14:25 |
kanzure | and bytes | 14:26 |
kanzure | conservation of bits | 14:26 |
fenn | there's already a limit on the simulation memory size | 14:26 |
fenn | maybe you mean conservation of entropy | 14:26 |
kanzure | possibly, yes | 14:27 |
fenn | wolfram showed that weird stuff happens even in severely entropy constrained systems, i.e. rule 34 | 14:27 |
kanzure | ynotds has spent like a thousand hours looking at rule 34 simulations | 14:28 |
kanzure | http://www.thewildca.com/200000r/snake0401_200000r.gif | 14:29 |
kanzure | http://ynotds.com/ under "Cellular Automata Project news" | 14:29 |
poppingtonic | and that other dude showed that UTMs can be made of extremely simple components. | 14:29 |
kragen | poppingtonic: ? | 14:30 |
kragen | are we talking about automata theory or mechanical engineering here? | 14:31 |
poppingtonic | Both. | 14:31 |
fenn | ok that's not an animated gif | 14:33 |
kanzure | that may just be how golly dumps images | 14:34 |
poppingtonic | you should download golly and run a few guns/spaceships. If you haven't already. | 14:35 |
kanzure | to be honest i do not find cellular automata very interesting at all | 14:36 |
narwh4l | ^ | 14:36 |
narwh4l | They are neat, like fractals but somehow less useful | 14:36 |
fenn | you know rule 34 is just an instruction set | 14:37 |
kanzure | what about it? | 14:37 |
fenn | it's not any different from the code alife stuff you're looking at | 14:37 |
fenn | except time is shown on the y axis | 14:39 |
narwh4l | kanzure as a fringe topic that might be relevant but probably is not, you might find it useful to read about quines | 14:40 |
narwh4l | http://en.wikipedia.org/wiki/Quine_%28computing%29 | 14:40 |
kanzure | fenn: then something is fundamentally wrong | 14:41 |
kragen | poppingtonic: so who is that other dude that showed that UTMs can be made of extremely simple components? Was it the same guy who showed that you can build them mechanically out of simple components and who showed UTMs that are simple in automata theory? | 14:41 |
kanzure | neighbor update rules seem very different to me. i agree that UTMs have been demonstrated using patterns inside different cellular automatas with various rulesets, but why should i care? | 14:42 |
kanzure | you know, i think this webcam may be on a loop | 14:42 |
fenn | it's just turtles all the way down | 14:42 |
poppingtonic | kragen: https://en.wikipedia.org/wiki/Wolfram%27s_2-state_3-symbol_Turing_machine | 14:44 |
poppingtonic | Alex Smith. That's the name. | 14:44 |
fenn | a turing machine is a special case of cellular automata | 14:45 |
poppingtonic | I don't think it's the same guy who showed | 14:45 |
poppingtonic | that you can build them mechanically out of simple components | 14:45 |
kanzure | i think you mean "a special case of the computation that can be performed by cellular automata" | 14:50 |
kragen | poppingtonic: any leads on actually physically constructing one? | 14:51 |
kanzure | "Around 2000, Matthew Cook published a proof that Rule 110 is Turing complete, i.e., capable of universal computation, which Stephen Wolfram had conjectured in 1985. Cook presented his proof at the Santa Fe Institute conference CA98 before the publishing of Wolfram's book, A New Kind of Science. This resulted in a legal affair based on a non-disclosure agreement with Wolfram Research. Wolfram Research blocked publication of Cook's proof ... | 14:52 |
kanzure | ... for 2 years.[1]" | 14:52 |
kanzure | "The original emulation of a Turing machine contained an exponential time overhead due to the encoding of the Turing machine's tape using a unary numeral system. Neary and Woods (2006) modified the construction to use only a polynomial overhead.[5]" | 14:52 |
poppingtonic | kragen i thought research in DNA computing did that already? | 14:53 |
poppingtonic | rather, *demonstrated that already* | 14:53 |
kragen | no, it didn't work | 14:55 |
kragen | also the things that came closest to working weren't close to Turing machines | 14:55 |
kragen | presumably someone will get DNA computing working at some point but so far nobody has done so AFAIK | 14:55 |

Most importantly, ... | 15:06 |
kanzure | ... though, in vitro selection experiments can give a true and quantitative idea of the likelihood that these scenarios could have played out in the RNA world.

fenn | i think what this constructor theory really needs in order to be relevant is some realization about the limits of working with noisy systems like Shannon's noisy channel coding theorem | 17:09 |
fenn | "it is possible to communicate discrete data (digital information) nearly error-free up to a computable maximum rate through the channel." i would add the relevant equation here but for hieroglyphics | 17:10 |
fenn | similarly constructors need substrate to work on, which is comparable to discrete data | 17:11 |
fenn | so it would be something like, "it is possible to construct artifacts (physical objects) nearly error-free up to a computable maximum rate in the workspace" | 17:14 |
