I'll soon be starting a project that is, for all intents and purposes, a superset of Evening Distribution. More details here when it's up and running.

Running headfirst toward the Denny Limit

Analyzing past records to predict maximum speeds for dogs, thoroughbred horses, and humans. The headline plateau record (the 'Denny Limit', from the paper's author Mark Denny): 9.48s for the 100m sprint, which is both very impressive and -as all explicit limits- bothersome. Why not 9.3s? What do we have to do to make it a cool 9s?

On one hand, we are not the first epoch that attempts to improve physical performance (or any other sort), nor are we the first ones to use then-current science and technology to do it. The appropriate null hypothesis might very well be that increasing scientific resources provide decreasing gains in performance, so while performance will keep improving, it'll do so with an eventually clear lower bound.

Nonetheless, I can't but think that this might not necessarily be the case. Engineering progressed in almost a linear fashion for thousands of years, but eventually knowledge of physics (most importantly, quantitative, mathematical knowledge of physics) opened the doors for a completely different rate of progress. We seem to be getting close to the point where human performance across the board becomes a matter of engineering, which would make models like the one in the article inapplicable.

Most of the time, the null hypothesis of sustained long-term tendencies is the best analytical framework. But 'most of the time' is becoming rarer these days, isn't it?

Core Business

As we go through the aftermath of yet another bubble, I think it's important to note that the very infrastructural core of the Internet isn't really profitable right now. Internet networking shares some of the characteristics of utilities, but there are also differences related to the multiplicity of underlying technologies, the relative independence from physical resource constraints, and the quick pace of technological change (if not always reflected in the infrastructure, definitely driving increased demand).

I'm not sure what Internet networking will look like organizationally and financially ten years from now, but it's probably going to be different from the past, and it's certainly going to be important.

Worth a read

September 2008's issue of Neuroinformatics, an Open Access online issue (one day this will be tautological) focused on the Neuroscience Information Framework, a wide assembly of online data and tools for neuroscience research.

Right now, besides maybe Google, scientific projects are what push the envelope of really large-scale, distributed, mathematically complex data-intensive processes. Most likely, business and governments will eventually follow suit, which will probably trigger another minor revolution equivalent to the introduction of the Internet.

Don't forget that the World Wide Web was first created at CERN (the people behind the Large Hadron Collider) precisely to deal with some of the problems of globally distributed research. In a way, the World Wide Web is but a collateral side effect of scientists' struggle to collect, analyze and distribute exploding amounts of increasingly sophisticated data.

Imagine the side effects of what scientists are building today...

The most profitable hacking target has always been your mind

A paper on the economics of massive advertising over email, and some numbers on the economics of massive advertising over search result pages. Both business models require sophisticated hardware infrastructures, but note that the search result pages-based implementation -due to the extra information in query terms- is much better targeted, and hence more profitable, than the email-based one (except when the advertiser has access to your mail history).

Obvious linear extrapolation: there'll be increased incentives to offer you online platforms to work, learn, and communicate, as the ever-growing volume and richness of the captured data allows more profitable advertising (or similar, think political campaigning, activism, etc) methods.

First Korea, then the world

Surprising nobody but Hollywood companies, the DVD business model is beginning to collapse.

Wars will be fought about water, and not only in the sense you think

As Gibson implied, the future comes first in scattered places: The incoming president of the Maldives has announced that the country will begin saving to buy a new place for its people to live, in case the islands are flooded by rising sea levels. It's actually not a bad idea, as the Maldives are only one meter above sea level, which is less than the rises predicted by some climate models. Its population is a bit less than four hundred thousand people (somewhat more than Iceland's, in case you were wondering). It'd certainly be a nontrivial migration project, but that's more the reason to begin to plan it as early as possible.
