[Uncommon Descent] Writing Computer Programs by Random Mutation and Natural Selection ...: Additionally, RBH claims that these algorithms are not models of biological evolution but â┚¬Ã…“only of cumulative selection and its power to transform tiny probability into high probabilityâ┚¬Ã‚. One of Darwinian theoryâ┚¬Ã¢„¢s fundamental claims is that undirected biological evolution has the power to climb such â┚¬Ã…“Mount Improbablesâ┚¬Ã‚ (Dawkinsâ┚¬Ã¢„¢ phrase).

[Thinking Christian] “Is Religion Adaptive? It’s Complicated” ”” Scientific American ...: it’s more efficient, in the total darkness in which these fish have flourished, to no longer bear the cost of maintaining a working organ that offers no benefit.) While not up there with the “how come we don’t see any fish spontaneously evolving into a dog” comments I’d say this approach from personal incredulity either tends to mis-state what is expected from the evolutionary process or has a poor record for withstanding focused research when the problem appears real (eyes, bacterial flagellum, etc.). Long way to say that it’s a (famous) strawman to claim that evolution is supposed to be a never failing advancement toward a single uber-species that can fly, shoot lasers out of its eyes, is impervious to gunfire, etc.

[The Oil Drum: Australia/New Zealand - Discussions about Energy, Transport and a Sustainable Future] The Oil Drum: Australia/New Zealand | Biomimicry and Ocean ...: Eventually, it soon became painfully apparent to the more astute experimenters in flight that trying to emulate the action of birds in flight was a hopeless technological deadend. Hence, the successful early pioneers of flight embarked on a radically different approach: don't try to mimic the birds, but rather develop a means of attaining flight unique to the human physiology and human technological capabilities.

[Uncommon Descent] Can we make software that comes to life? | Uncommon Descent: If you are, as I have done in the past, trying to artificially evolve a neural network to perform a particular task then surely the measure of complexity should be applied to the parameters being evolved - the configuration of the network. The underlying software doesn’t have to change, although it can if you are using a variable size network - in other words the network can grow in size and consequently in complexity, which is reflected in the way the underlying software uses memory and fills it with new data.

[iMechanica - web of mechanics and mechanicians] What is the status of open source finite element code? | iMechanica: For a first graduate course in FEM (any cross-section of engineering/applied sciences students), Matlab serves as a suitable platform since it enables the students to focus on the implementation of the method and not on getting bogged down by the details of the language.  Furthermore, on using Matlab,  matrix/vector operations and linear algebra (solution of linear equations) can be accomplished using simple commands, and visualization of results is greatly facilitated. However, Matlab's power can not be undermined since there are many researchers in the computational sciences who solely use Matlab for their research. 

[Uncommon Descent] Gambler’s ruin is Darwin’s ruin | Uncommon Descent: Skilled gamblers, like those who were part of the MIT team did not play games that had conditional independence (like roulette), but games where the probability of an outcome was influenced by the observation of past events. Their minds were sufficiently keen to be able to recognize when table games offered an avantage.

[ScienceBlogs Select] Pharyngula: Brunswick school board may be OK”¦for now: And I can easily see how that rough-and-ready, practical attitude to descriptions and problems makes engineers uniquely susceptible to creationist claims when contrasted with, say, biologists or theoretical physicists. For many of the people I know with an engineering mindset, the modern synthesis will remain largely uninteresting speculation about our past not worthy of too much mental energy until such time as they have an application which requires the use of genetic algorithms or neural network logic.

[WE Blog] Open thread 1/16 | WE Blog: Steve McIntyre says here, “If the supposedly “rural” comparanda are actually “urban” or “small” within the Hansen definitions, then the GISS “adjustment” ends up being an almost completely meaningless adjustment of one set of urban values by another set of urban values. No wonder these adjustments seem so random.”

COC interactions with CYP3A4 may affect/ be affected by PIs andNNRTIs.

[Nick Lewis: The Blog - Drupal, CSS, Web Development, and the Myriad Iconoclasts] A Renaissance of the Commons | Nick Lewis: The Blog: David Sloan Wilson, an evolutionary biologistwho has written extensively on natural selection and cooperation, writes that "socialgroups become so functionally integrated that they become higher-evel organismsin their own right."5 At such a point, evolutionary pressuresappear to play out at the collective level, not just at the genetic andindividual level. (There is a spectrum ofviews about the level at which natural selection is most influential -- group orindividual -- but not even Darwin was as radical an "individualist" as manycontemporary scientists such as Richard Dawkins, author of The SelfishGene.)6

[Charlie's Diary] Charlie's Diary: Shaping the future: Extrapolating, if the technology for wireless information transfer and the culture of not expecting personal information to be private follow the trends suggested in Charlie's essay then perhaps we have a situation as suggested by Queegmire above, that people can and will choose to dump portions or even the entirety of their life log onto public safe storage or to friends and aquaintances.
