I’d rather be me, right now, right here —an upper middle class 22-year-old male Mexican in Guadalajara—, than any other human —emperor, king, sultan, noble, philosopher, artist, scientist, genius,...— from any time before, any place. We have been humans for some 15 thousands years and there’s no time past I’d rather be at.
I don’t mean this as some outburst of excitement, it’s just a calm realization that downed on me a while ago, out of the blue—a surprising measure of the reality of progress, the splendor of the present, the promise of the future.

Just think of the responsibility, the challenge, the opportunity. One third of the population is still young enough to be natural born digital citizens (see Classmate PC and the OLPC XO laptop), to easily master an international language (whichever one), to be taught about doubt (“Just think of the tragedy of teaching children not to doubt…”), to receive the best education we can give them…
Remember that character in Neal Stephenson’s Diamond Age, catatonic at page 169 at discovering a quarter million Chinese girls thrust to his care? Well, look around and realize we’ve been given a ship of 1.8 billion souls. Just think of the opportunity.

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 hold” 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 distribute” 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.
| The simplest way to do the Turing boogie | 2 0 0 7 |

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?

What structure would you give to Mexico’s 2006 GDP, the wealth it generated in a year? Just gather your prejudices, take a guess, and try to put it into numbers.

Speaking of locality, if you haven’t seen Google’s new Streetside View (like, say, in San Francisco) you’re missing a future shock gasp. (via O’Reilly Radar)
Breathtaking immersion. Eerily reminiscent of Rainbows EndWP, AM.
Also not to be missed are Immersive Media’s—one of the companies behind this new feature—richer demos: pannable videos!

Think of the arms races that go on between one or two animals living the same environment. Fex the race between the Amazonian manatee and a particular type of reed that it eats. The more of the reed the manatee eats, the more the reed develops silica in its cells to attack the teeth of the manatee and the more silica in the reed, the more manatee’s teeth get bigger and stronger.
