This just in (via KurzweilAI.net), I can hardly believe it myself:

[..a scientific team] has discovered that sexual orientation in fruit flies is controlled by a previously unknown regulator of synapse strength. Armed with this knowledge, the researchers found they were able to use either genetic manipulation or drugs to turn the flies’ homosexual behavior on and off within hours.

”Homosexual courtship might be sort of an ‘overreaction’ to sexual stimuli,”..

For those armchair observers of the breathtaking world of quants and structured finance, as myself, Technology Review’s current issue carries a wonderfully didactic and gripping introduction, The Blow-Up: (pesky but FREE registration required).

“How many think spreads will widen?” she asked.

The hands of about half the smartest people on Wall Street shot up.

“And how many think they’ll narrow?”

The other half—equally smart—raised their hands.

“Well,” she said. “That’s what makes a market.”

If they didn’t know, nobody could.


Focused only in securitization, When it goes wrong, from The Economist (YubNub’s “eco“), is also a good overview and glimpse:

..it is hard to overstate the effect that securitisation has had on financial markets. Until the early 1980s, finance hewed to an “originate and holdâ€? model. Banks generally held loans on their balance sheets to maturity; some debts were sold on loan-by-loan, but this market was small and lumpy. This began to give way to an “originate and distributeâ€? model after America’s government-sponsored mortgage giants issued the first bonds with payments tied to the cash flows from large pools of loans.

Wall Street built on this innovation, and securitisation took off soon after, then paused before exploding in the 1990s.. It was given a lift by America’s savings-and-loan crisis, which encouraged mortgage lenders to jettison their riskier loans, and by new technologies, such as credit-scoring, that facilitated loan-pooling. Around 56% of America’s outstanding residential mortgages were packaged in this way, including more than two-thirds of the subprime loans issued in 2006. Thanks largely to securitisation, global private-debt securities are now far bigger than stockmarkets.

Answers.com (YubNub’s “a“), btw, is invaluable in navigating jargony fields like finance.

Que puta entre sus podres chorrearia

por entre incordios, chancros y bubones

a este hijo de tan multiples cabrones

que no supo que nombre se pondria?


Salvador Novo en Un Marof,
poema que forma parte de Sátira,
su colección de diatribas

podre = pus

incordio = tumor

chancro = ulcera sifilitica

bubon = ulcera sifilitica, particularmente en las ingles

A piece of Peirce 2

Charles S. Peirce has been called by Britannica “the most original and the most versatile intellect that the Americas have so far produced.” Bertrand Russell considered him “one of the most original minds of the later nineteenth century, and the greatest American thinker ever,” and Karl Popper goes all out, seeing him as “one of the greatest philosophers of all times.”

I just met him a couple of weeks ago and I couldn’t be more impressed: the man’s a fricking genius, practically inventing semiotics and modern logic, making major contributions to the philosophy of science and epistemology. I would remember him forever just for his offhand naming of math as the “hypothetical or conditional science.” (the could science? the moot science?) and I have the sneaking suspicion that ours will be a lifelong acquaintance.

How not to be intrigued by a man who could explain reason in a sentence?

For reasoning consists in the observation that where certain relations subsist certain others are found, and it accordingly requires the exhibition of the relations reasoned within an icon.


OK, to fully get the above quote you should be familiar with Peirce’s brilliant and influential classification of signs into ”icons, which signify by virtue of resemblance [think painting], indices, which signify by virtue of a physical connection with the object [think weathervane or tally], and symbols, which signify by virtue of the existence of a rule governing their interpretation [think words].”SOURCE

Then there’s Peirce “discovery” of abductive reasoning, the third major class of logical reasoning and for which I’ve found no better (or shorter) intro than the logical reasoning pedia.

And to finish this Peirce appetizer you must check out Peter Skagestad’s Thinking With Machines article. He gives a summary of Peirce’s semiotic to make a most intriguing comparison with the thought of human intelligence augmentationists like Doug Engelbart ELZR. Fascinating stuff really.

Genders <= 2? Why? 2

Life is a sexually transmitted disease.
-Anonymous

By focusing on the number of individuals (genders) required for reproduction we can distinguish species into three classes: those that require one individual (self-reproducers), those that require two (pair reproducers), and those that require three or more (group reproducers). The question is thus: are there group reproducer species? why?

We usually refer to the first class as asexuals, the second as sexuals, and it is a major puzzle of evolutionary biology to account for the existence of the latterD, WP. Like the bee that fluttered in the face of our best aerodynamic theories, sexuals mate impudently in the face of our best evolutionary theories.

But sexuals exist. Everywhere, in fact, at our order of magnitude. So we can’t just sweep pair reproducers aside and carry on our happy, simple theorizing of a self-reproducing world.

Asking the group reproducer question, on the other hand, I’ve been surprised by people to whom it comes as a revelation that the class is obviously empty. I don’t think it is. Obvious, that is. Life on earth does some pretty fucked up stuff, natural gangbanging doesn’t strike me as particularly eccentric. Asimov describes a group reproducer species in great detail in The God Themselves and neither the author nor I (before) ever thought the point merited any explanation.

And if there are no group reproducers (or precious few) their non-existence (or extreme dearth) is as much a fact in need of explanation as their existence (or abundance).

How to bring peace to Israel and Palestine 2

Am I not destroying my enemies when I make friends of them?

Abraham Lincoln, attributed

E Pluribus Unum (From Many, One)

Traditional U.S. motto

Transhumanist transgender Martine Rothblatt proposes the most original solution to the Israeli-Palestinian conflict I’ve ever conceived: Two Stars for Peace—the incorporation of Palestine and Israel into the U.S. as the 51st and 52nd states. She has wrote a book making the detailed case and has spoken about it on Sirius satellite radio:

A young person in Palestine and Israel today looks forward to future with depression and with fear, but with Two Stars for Peace, the young people of Israel and Palestine can look forward to a future when they can travel freely throughout the United States, get their education in any part of the United States, or they can travel back and forth between Israel and Palestine. They can look forward to a future of instead of warring armies, everybody is part of a single United States army. The young people have no vested interest in the past of bickering and hostility. It’s depressing. But Two Stars for Peace gives them a way to have a good life.

This is so far out our ordinary could I’m still shocked. My rather unusual Mexican high school put an odd emphasis on the Middle East and this is by far the best idea I know of. Just imagine, fighting war with peace. Hope. Freedom.

How to shoot at someone who outdrew you 2

I’m making a list of fascinating things about the English language. As, say, my interviewer at frog design can attest, I overflow with opinionated passion but suck at showcasing. I overtell and undershow. I’m constantly nagging people with my fawning for English, for its beauty, expressiveness, and flexibility, but when pressed to put my love into reasons I’m as vague and mushy as a Christian.

Faith: Lisa, I’m Faith Crowley, Patriotism Editor of Reading Digest.
Homer: Oh, I love your magazine. My favourite section is How to increase your word power. That thing is really, really… good.
The Simpsons, Episode: Das Boot, the lord of the flies / bill gates parody (via Subtly Simpsons)

So I do lists. And this particular one is fairly advanced, with so many items and examples that there’s a multi-leveled hierarchy already. One of its headings is titled “informal, unique, almost idiomatic affixes”—y’know, stuff like she- (“the she-Shepherd“), out- (“innovators out-fail the competition”), over- (“don’t overdo it”), -away (“assume away”), -friendly (“gay-friendly”), -up (“trade up”), and so on. I find most of them not only unique to English but uniquely expressive.

One particularly good example is in the phrase in the title. The full context comes from a verse from Leonard Cohen’s Hallelujah (you can listen to it here, covered by Rufus Wainwright):

..all I ever learned from love
was how to shoot at someone who outdrew you

The lyrics manage to portray tragic, flawed love in two lines and it all hinges on that magic “outdrew” verb.

The simplest way to do the Turing boogie 2

A math experiment was carried out recently when Alex Smith —an Electronic and Computer Engineering undergraduate with “a background in mathematics and esoteric programming languages”— proved that the Turing machine below is in fact universal, making it the simplest universal Turing machine possible. In other words, the cute graph below are the instructions for an abstract symbol-manipulating machine that can in principle do anything your computer (or any other computer for that matter) can do.

Stephen Wolfram, who made the conjecture and offered a $25k reward for proving it, reports:

We’ve come a long way since Alan Turing’s original 1936 universal Turing machine—taking four pages of dense notation to describe.

We did an experiment; and PCE [the Principle of Computational Equivalence] was validated.

But unlike some science experiments, it didn’t take a multibillion-dollar particle accelerator. It just took a 20-year-old undergraduate with a PC.

[It’s] a wonderful monument in the computational universe—a marker at the edge of universality for Turing machines.

It’s a very satisfying way to spend $25,000.

Now, ain’t this just breathtaking?

People who seem to have had a new idea have often simply stopped having an old idea.
Edwin Land, inventor of Polaroid
If you are in a hurry, jump ahead to the 3-minute screencast to see what this is all about.

Not for the first time I’ve woken thinking that the invention of dirt-cheap, high quality multi-touch wallscreens would prove as epoch making as the printing press, a cure for cancer, or the web. Most people, of course, scoff. They can barely see the point of computer screens bigger than 15”. It is not my intention now to disabuse the heathen. Let’s just assume that we have such wondrous interfaces and see how far we can run with them in one particular direction.

Close your eyes and imagine that you somehow —digital contact lens, projectors, VR goggles, pixie dust— have access to a screen at least as big as a wall—a humongous HD screen that is not only a pleasure to look at but with which you can interact. Mouse and keyboard would suffice for our purposes here, but since we’re dreaming, feel free to indulge in Jeff-Han-style touch interaction.

Despite the mind-boggling immersive multimedia we can expect, text won’t go away. Not only will we still gulp it down, we’ll likely drown in it. Text has advantages all of its own and in a digital word there’s nothing cheaper or more malleable. Reading newspapers, books, magazines, blogs, emails, and tutorials will still be an everyday staple. It’ll just be by and far all digital now.

The question thus is how we’ll read all this text. How do you take advantage of a massive pixel landscape when your goal is reading? You could recreate books in all their physicality, down to the flashy turning of pages, the weight, the fixed dimensions, and the mahogany bookshelf. We would certainly be able to copy it all in breathtaking detail, but limiting ourselves to such molds wouldn’t only be wrong, it would be perverse. Let’s see if we can do better than that.

Via Richard, un bizarrisimo video local: La Tapatia de El Personal. Producido por alumnos del CUAAD WP, el video es practicamente una guia sui generis del centro de Guadalajara.

Nos subimos al par vial
visitamos Catedral
la pasee por todo el centro
nos clavamos muy adentro
vimos bicis, vimos motos
y en la calle muchos jotos…

Ah, no se, es tan malo que es bueno… Ademas de que siempre es raro ver cultura local capturada en medios como el video y la musica.
