Heard in interview with James Gleik on Science Friday
In the 17th century Leibniz bemoaned the “horrible mass of books which keeps on growing,” and in 1729 Alexander Pope warned of “a deluge of authors cover[ing] the land,” as James Gleick describes in his new book, The Information.
Heard on Science Friday (or was it Sci Am?) about 9 months ago: unnecessary obstacles
One interesting comment:

September 13, 2010 at 10:21 pmI have been (and remain) a long-time R user and fan. Lately, however, I find myself learning/using Clojure (clojure.org) with Incanter (http://incanter.org/).
The main reasons for this are (1) memory issues for big data using R, (2) the paradigm of a language deeply rooted in functional programming, (3) concurrency, (4) Java-interoperability as Clojure runs on the JVM, and (5) immediate use of the vast number of incredible Java libraries available (e.g. hadoop, mahout, weka, etc…), to name a few.
I would be very curious as to how Ross and others view Clojure in the space of the future of statistical programming.
Many thanks.

In CACM, Jan 2007, V50N1, p85-93. Has some interesting comments about the nature of language & cognition, & refs to William James & Otto Jespersen
"Safe" module (ch 23.3 in "Programming Perl, 3rd ed) (sandbox)
Some interesting ideas here about the evolution of morality (& language...), e.g.:
Furthermore, Damasio and Bargh both found, as Michael Gazzaniga had years before, that people couldn't stop themselves from making up post-hoc explanations for whatever it was they had just done for unconscious reasons. Combine these developments and suddenly Kohlbergian moral psychology seemed to be studying the wagging tail, rather than the dog. If the building blocks of morality were shaped by natural selection long before language arose, and if those evolved structures work largely by giving us feelings that shape our behavior automatically, then why should we be focusing on the verbal reasons that people give to explain their judgments in hypothetical moral dilemmas?
Moral thinking is for social doing. This is a play on William James' pragmatist dictum that thinking is for doing, updated by newer work on Machiavellian intelligence. The basic idea is that we did not evolve language and reasoning because they helped us to find truth; we evolved these skills because they were useful to their bearers, and among their greatest benefits were reputation management and manipulation.
Good summary of some issues re sparse neuronal activation.
Is there other work in neuroscience or AI that interests you?
Very little. There are 20,000 or 30,000 people working on neuronetworks, and there are 40,000 or 50,000 people working on statistical predictors. There are several thousand people trying to get logical systems to do commonsense thinking, but as far as I know, almost none of them can do much reasoning by analogy. This is important because the way people solve problems is first by having an enormous amount of commonsense knowledge, like maybe 50 million little anecdotes or entries, and then having some unknown system for finding among those 50 million old stories the 5 or 10 that seem most relevant to the situation. This is reasoning by analogy. I know of only three or four people looking at this, but they're not well-known because they don't make grandiose claims of looking for a theory of everything.

Researchers Teach Robots To Evolve Their Own Language
Researchers from Sony and elsewhere are working to give robots linguistic and cognitive skills that grow and develop spontaneously over time, without communication rules from humans.

Sony killed off its Aibo line of robotic dogs this year, but scientists with the consumer electronics giant are spinning off a litter with new brains. The research could ultimately produce far more advanced forms of artificial intelligence.
Researchers at Sony's computer science labs in France are working with the European Commission's Emerging Technologies Initiative and the Institute of Cognitive Science and Technology in Italy under a program called EC (embedded and communicating) Agents. Their mission: Give robots linguistic and cognitive skills that develop on their own over time, without communication rules from humans.
In one application of the technology, the researchers gave a pack of Aibos the ability to develop their own language. So, for instance, one dog can tell another the location of a ball and ask it to go fetch. It can also specify whether the ball is rolling.
Making sounds helps the super-Aibos fulfill a programmed requirement to learn more about what's around them. The canine cyborgs were placed in a room with other objects, some of which would respond to sounds. A stuffed elephant and other objects would not respond. The dogs ultimately spent more time "barking" at the responsive objects, and they learned that particular bark patterns elicited certain responses.
The researchers think such interactions are the beginnings of artificial intelligence with an innate language capability--one they hope to develop further. "The result is machines that evolve and develop by themselves without human intervention," Dr. Stefano Nolfi, the coordinator of the EC Agents project, says in a statement posted on the project's site.
Another participant in the project, Sweden's Viktoria Institute, is using EC agents to let mobile devices, such as MP3 players and cell phones, "talk" to each other. That way, a device belonging to, for example, a person who's part of an online social group would know what songs are played frequently by devices owned by other group members and could automatically push those tunes to the person.
The Swiss Federal Institute of Technology is teaching hordes of small, wheeled robots embedded with EC agents to swarm over areas to help with search and rescue operations. "We've managed to ground AI in reality, in the real world," says Nolfi, "solving one of the crucial problems to creating truly intelligent and cooperative systems."

Di Filippo's story "Little Worker" as a podcast
Today the Escape Pod podcast included a wonderful short story by Paul Di Filippo, a consistently great science fiction writer. The story is "Little Worker" and it's pure gold Di Filippo, a reprint from his collection of bio-punk stories Ribofunk The reading by Jonathon Sullivan is likewise stellat. Escape Pod features some great fiction, but with this story, they've really gone to a new level. Bravo!
At home, Little Worker could do pretty much as she pleased, as long as she was there should Mister Michael need her. At the office-and in other public places-she had to be more circumspect and diligent. Little Worker was on duty her, in a way that was more intense than behind the electrified fence and active sensors of the estate. (Once, one of the men at the Training School had said: "Little Worker, you are the most diligent companion I've ever trained." The men of the school had been nice, in their stern way. But no one was like Mister Michael.)
Today, however, Little Worker's mind was not on her work.

Things That Go Bump in Physicists' Night
Truth be told, physicists are terrified of quantum mechanics. Really. The rules of quantum calculation seem so strange that anyone afraid of losing his or her mind should be scared. (Those who love to lose their minds, on the other hand, adore it.)
Struggling to make the quantum rules square with a reality "out there," many physicist's position is "shut up and calculate." Others have abandoned standard logic, probability, or decision theory for "quantum" versions of these things, or have decided that consciousness must play a fundamental role. (There is even a quantum game theory.)
In eleven days I give my first talk at a physics department, on my conservative research program that tries to have it all: the quantum rules, a reality out there with no special role for consciousness, and keeping standard logic, probability, and decision theory. I'm not quite there yet, and I may be too close to my work to be objective, but I feel I'm very close.
Of course we can't make all the quantum strangeness go away. For example, reality seems to be intrinsically non-local, and it seems to be far larger than we ever imagined. But the universe we are all familiar with now is far larger than our ancestors ever imagined, and even Newton gave up on locality.
Fear not the quantum night - it really will all make sense someday.

Let's see if I can include an image from internet explorer:
How do I post pictures?
Blogger does not directly provide image hosting, although you are welcome to include any images in your blog if you have them stored online elsewhere. However:
