Life Results from the Non-Random Survival of Randomly Varying Replicators.
My answer to life, the universe, and everything:
Randomness begets persistence
For among things that vary a lot,
and vary varyingly (= non-independently = causally),
what varies little remains (duh!)
Persistence begets replication
For among things that persist,
what copies itself is an outbreak
Replication begets complexity
For among the ways to copy oneself,
the more successful ones are among the more complex
(for there are many, many more complex ways than simpler ones)
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.

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.
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.

Fascinating Economist article on the music industry’s new developments. Very reminiscent of Dyson’s thoughts on intellectual property:
“[...it] is dead; long live intellectual process. Long live service; long live performance.”
and anime’s general stance towards piracy:
“If it succeeds, milk it; if not, try something different. And if the fans are into file sharing (which they are), keep the lawyers leashed and find a way to make piracy work for you.”
Seven years ago musicians derived two-thirds of their income, via record labels, from pre-recorded music, with the other one-third coming from concert tours, merchandise and endorsements, according to the Music Managers Forum, a trade group in London. But today those proportions have been reversed—cutting the labels off from the industry’s biggest and fastest-growing sources of revenue. Concert-ticket sales in North America alone increased from $1.7 billion in 2000 to over $3.1 billion last year, according to Pollstar, a trade magazine.
Frustrated record companies have responded by trying to get their artists to spend more time promoting records and less time touring and endorsing products, says Jeanne Meyer of EMI, another big record label. “Sometimes you’ve got a tug of war going on,” she says. Yet the more labels spend on marketing pre-recorded music, the more they raise their artists’ profiles and boost their other, more lucrative, sources of income. Pre-recorded music, no longer the main cash cow, increasingly serves merely as a marketing tool for T-shirts and concert tickets. The best seats for The Police’s world tour this summer cost over $900; the group’s entire catalogue on CD costs less than $100.
The shift away from recorded music is due in part to the recognition that touring and merchandise are more lucrative. But it may also be a consequence of internet piracy, as free downloads give music fans more money to spend on other things. Jwana Godinho, the director of Música no Coração, a concert promoter in Lisbon, thinks many music lovers have a “mental budget” that they are prepared to spend on music, and have switched their spending from CDs to tickets and merchandise.
The logical conclusion is for artists to give away their music as a promotional tool. Some are doing just that. This week Prince announced that his new album, “Planet Earth”, will be given away in Britain for free with the Mail on Sunday, a national newspaper, on July 15th. (For years Prince has made far more money from live performances than from album sales; he was the industry’s top earner in 2004.) Outraged British music retailers were quick to condemn the idea. As far as the record industry is concerned, it is madness. But for the music industry, it could well be the shape of things to come.
I’ve always hated, with a passion, moral-indignation ads against piracy—not only because they’re manipulative but because they’re stupid. And the best defense for piracy may be how hard it is to make an argument against it that doesn’t stink of moral indignation—if maudlin pleas are the best you can do, you’re probably rotten. (On a related sidenote, I found it mighty interesting when The Economist circuitously referred to Kazaa as “a file-sharing program that was widely used to download music without paying for it”—as much as ads want to make us believe pirating is stealing, there are crucial differences, which is why such circumlocutions are essential.)
To solve intellectual property’s malaise I’ve long sought for grand economic solutions (new innovative schemes or perhaps even a new concept of property rights) rather than grand political ones (which are just, ugh, imposed moral rules). While there has been plenty of both, I’m starting to see these days that maybe the solution will be simply to move on. Piracy is just another (admittedly extreme) form of commodificationWP. You don’t fight commodification by outlawing it, you take the next thing that hasn’t been commodified yet, you offer value however you can, you move on.
Which is quite amazing, I must say. Always thought the English colony would have English at the top, by far.
Check the US Census press release where this was reported for definitions and more context.
Considering several friends have bantered—semi-seriously—about starting an online Mexican porn ring, alluding of shocking wind-fall profits, and considering that last year “about 13% of website visits in America were pornographic in nature.. while search engines account for about 7% of site visits,” (Economist, Devices and Desires), it is quite a shock to find in the same article 2002 estimates of the (admittedly hard to track) online porn industry measuring it at only a billion dollars. Shockingly little, I’d dispassionately say.
Here 2 examples—a graph and a paragraph—from a typical article (about the paper industry’s dire prospects, of all things) in this week’s edition of The Economist.

Restructuring in the paper industry is proceeding at a furious pace. The first thing some paper companies have jettisoned is ownership of forests. International Paper (IP), one of the world’s biggest pulp-and-paper companies which is based in Tennessee, used to be the largest private landowner in America. A year ago the company sold 5.7m acres, or 90%, of its forestland—an area larger than Massachusetts. The $6.6 billion sale was “probably the hardest decision that I’ve had to make since I became CEO,” says John Faraci, IP’s boss since 2003. Most buyers were financial investors, but 5% of the land went to conservation groups.
Starting with the graph: it’s a 16-year window to worldwide newsprint production that drives home the article’s main point with eloquence: North America’s newsprint production (a fifth, you will notice, of the world’s; used to be a fourth) is slowly but decisively dwindling; production in the rest of the world, on the other hand, is increasing, albeit not in a hurry.
It’s full of conventions too, but they’re so well thought that you never need to be consciously aware of them as a reader: Take the upper-left red patch, a gentle way to guide your eyes to the graph’s title and instructions. The source always goes at the bottom, smaller-typed, and the y-axis is always labeled at the right, which I find more natural than the common left convention (it makes you look at the graph first, notice its pattern). The x-axis is usually the time axis, its gridlines usually obviated for clarity’s sake, and its labels, usually years, presented in a simple format that marks millennia only when needed. And graphs are always in this blue scheme—a convention to avoid color misinformation that still allows for meaningful distinctions between color shades: darker blue for the main variable under discussion, the foreground; lighter, fading blue(s) for the background variable(s).
As for the paragraph, it’s brimming with fascinating facts about the world. Did you know who the world’ biggest pulp-an-paper company was and that it was located in Tennessee (WP)—of all places? Did you know it also happened to be the largest private landowner in America? (A paper company! The largest private landowner in America!) Did you know it recently sold, because of restructuring, 90% of its forestland, 5.7m acres—an area larger than Massachusetts? Did you know it sold them for $6.6 billions? (Surprisingly cheap, considering it’s an area big enough for many a country.) Did you know most buyers were financial investors but 5% were conservation groups? (A wonderful example of how trade allocates resources, peacefully and quietly, to those who care about them.) Now you know.
...and yet you’ve gotta grant it to this stop-motion action-figure video: it’s pure comic genius. (2.3 million views!; 1,814 comments; 15,417 favorites; 6,648 ratings)
An impressive graph, both in execution and content, to be taken with one big grain of salt (read article for important considerations on the methodology and the difficulty of defining wealth):

Wealth is shared much less equitably than income: more than half of it is held by just 2% of the world’s adults. The distribution is equivalent to a world of ten people, in which one had $1,000 and the other nine had $1 each.
