Hans Moravec’s Mind Children is dated at parts but it is as lyric, visionary, and deep as anything I’ve read. Here 2 excerpts I particularly enjoyed: one on robot bushes (forget many-armed Vishnu, this will be the avatar of the gods), the other on artificial life, spontaneous and deliberate (a great story of a virus put deep inside Unix by Ken Thompson himself and a subtle but intriguing example of spontaneous alife).
I’m experimenting with taking quick page snaps and bundling them into PDFs, so these are rather crude. No matter, it’s early days and I’ll get better at it. PDF/CBR is the new MP3!
Been playing with travel sites all day, (Kayak FTW!) and I discovered several interesting anomalies with which I plan to tour the world for some $2k in air travel. Flight arbitrage, if you will.
Guadalajara ↔ Toronto ↔ London ↔ Tokyo (at least!)
You see:
- Travel within Europe is really, really cheap. As in
€30 £5 London – Madrid round trip. So Europe can be thought of as one point: London, by far the cheapest hub.
- Round trips are a considerably better deal than one-ways. I understand they are the industry’s version of wholesaling but a 40% difference seems too much (a one-way can be 140% the price of either round trip leg)%.
- Travel order is everything. Mexico-Tokyo, one way is some $900. Tokyo-Mexico, one-way too, no less than $2,000! That’s right, the exact same distance can cost you over twice as much depending on where you start!
Putting it all together, my plan is to buy the following round trips: Guadalajara-Toronto, Toronto-London, London-Tokyo. I travel from Guadalajara to Toronto, then to London, then to Tokyo, where I stay 3 months. Then I return to London, where I stay some 6 months (to travel cheaply around Europe), then I return to Toronto and stay some 3 months, and only then do I return to Guadalajara.
All this for some $2k!
It’s a tad complicated and wasteful, and I need to plan far ahead, but the price’s pretty good, right?
Can you think of something else?
Know any other anomalies? Youth discounts? Passes?
Got any tips?
I haven’t bought yet but I think I will soon!
Game: 2 players take turns to say a number between 1 and 9. Numbers may not be repeated. The goal is to be the first to say 3 numbers which add up to 15.
Sounds like fun? Try it with a friend!
Fun it ain’t.
It’s hard to remember the said numbers and “playing” is a chore involving many additions in your head. Maybe it’s fun for the better short-term memory endowed or those who enjoy arithmetic but that ain’t me.
Turns out that game above is none other than the beloved tic-tac-toe. You see:
This is what I love about information design (and what I tried to do in my calendars) this is its art, its magic: it can turn a chore into a game! It recasts our weaknesses —linear, verbal processing— into a form suitable for our talents —gestalt visual processing.
In math words: it finds useful language-graph same-shapes (isomorphisms)!
All the world is full of knowing men, of most learned schoolmasters, and vast libraries; and it appears to me as a truth, that neither in Plato’s time, nor Cicero’s, nor Papinian’s, there was ever such conveniency for studying as we see at this day there is. Nor must any adventure henceforward to come in public, or present himself in company, that hath not been pretty well polished in the shop of Minerva. I see robbers, hangmen, freebooters, tapsters, ostlers, and such like, of the very rubbish of the people, more learned now than the doctors and preachers were in my time.

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.

People who seem to have had a new idea have often simply stopped having an old idea.

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.
...Is how Peter DruckerWP drives it home. “It” here was not originally the free market, though what a great defense for it it makes, no? Drucker was illustrating, rather, his brave belief that strong people always have strong weaknesses, that it is foolish to concern oneself with what a man cannot do instead of what he can, that the man who “leaves least to be desired” is invariably the mediocrity, that one builds on strengths, not on weakness. Moreover, that making strength productive and weaknesses irrelevant is “the unique purpose of organization.” A great short book, The Effective ExecutiveAM.
