Which is in itself quite wonderful news (artificial languages need all the help they can get), but the Globe and Mail article is also one of the best introductions to the language I’ve seen, so do check it out—web version or print scan—if you’re interested in Toki Pona (and if you speak Spanish, don’t forget to check out my Spanish manual on it).

Flickr AutoPagination has got to be the coolest Greasemonkey script I’ve seen yet, and, to judge by its code, a really intricate labor of love. It works flawlessly and does exactly what you’d guess: it makes every Flickr page (where it would make sense) “infinitely scrollable”. A cool, handy, and surprisingly stable script.

Why do we call something a “number”?: Well, perhaps because it has a “direct” relationship with several things that have hitherto been called number; and this can be said to give it an indirect relationship to other things we call the same name.

And we extend our concept of number as in spinning a thread we twist fiber on fiber. And the strength of the thread does not reside in the fact that some one fiber runs through its whole length, but in the overlapping of the fibers.

Ludwig Wittgenstein, Philosophical InvestigationsEEM



Always have loved them. Always have obsessed about them. I treasure my favorites and revisit them again and again—I could barely think without them. I have a tag for them in this blog (here) and I almost started “a collection of beautiful definitions” to go with my eemadges website (“a collection of beautiful descriptions”).  A good definition more than justifies a whole book. A good book always has many good definitions in it. Good people always carry several good definitions with them—you just have to know how to tease them out.

And yet I seem to get into all kinds of tiresome, silly discussions when I try to share them with friends. Besides my not to be belittled incompetence as an explainer and my fabled monomanias, I believe a basic misunderstanding regarding their nature is at the heart of the matter.

You see, most people seem to never have moved over the idea of a definition as distilled truth—the one true essence which both captures everything that should be captured and leaves nothing that shouldn’t be left out. Definitions as platonic ideals—the perfect divine forms of which we only see shadows. The one golden fiber that runs trough all the thread.

The problem with this view, of course, is that it is crippling in its obsession with perfection. It intimidates and nurtures ridiculous expectations. If we had had to delay mathematics until we had a “perfect” definition of number we would still be waiting.

In their supposed perfection, definitions only become cages. And we easily get to the point when not only it isn’t believed that things like “love”, “mind”, “conscience”, or “happiness” could ever be defined (again, as if there was one true definition to rule them all), but the very possibility is viewed with dread. Dread that what once was magic and alive is cramped and crippled into a cage.

A much more interesting view of definitions, in my opinion, is to regard them as tools for thought, and as such, to value them on their usefulness and pick the one appropriate for the task at hand—platonic truth is only one of the many, many things we can ask of them. Most importantly, we ought to recognize that we need them—a brain unaided can do only so much. Thinking without them is like hammering with your bare fists—it’s painful and ineffectual. Yes, they are only one (verbal) kind of tool and we run the risk of starting to see everything as a nail, but they are still one of the most basic and powerful tools we have and they have so far been needlessly feared and vilified.

Definitions are semantic flashlights, casting light on some meaning corners, shadow on some others. That everything be alight is only one criteria (ultimately impossible; only emptiness can be shadelessly illuminated), there are others—that it be bright, that it be dim, that it illuminate (or obscure!) a particular patch, that it be pristinely white, that it tint its subjects with its color, that it be diffuse, that it be focused, that it be favorable, that it be unfavorable… We say, teasingly, that an American is a “man with two hands and four wheels” not because we believe that it happens to be a perfect embodiment of what it means to be an American, but because we believe it casts them in an interesting light.

So the effort to define “play” or “capital” or “freedom” is not to pin the butterfly down and put it in formaldehyde, it’s to find new ways to look at it, new sources of joy and understanding. Definitions do not diminish their subjects, they reveal them.

We will come to think of interface design as a kind of art form
—perhaps the art form of the next century.

Steven Johnson, Interace Culture, p213


Dasher
hit escape to halt animation
“Hello, how are you?” being written in Dasher. (Hit escape to halt animation.)

A text-entry interface for the tetraplegic, it’s like nothing you’ve seen. Not only does using it have the same rush and exhilaration of playing SonicWP, it is also unbelievably efficient. And again, sheer fun.

It will take you some 5 minutes to get the hang of it (not out of difficulty, out of profound weirdness) but believe you me, you won’t regret it. Read the quick, 3-page explanation and try the Java version in-browser or download it. It’s free software and there are localized versions in many languages.


If such deep novelty, such striking unrealityELZR lies in something as mundane as text-entry, what wonders lie yon in the craft of interface design?


Scratch

Visual programming has been a perennial pipe dream of mine and just some three months ago the MIT Media Lab unveiled the best embodiment so far of my vague and unspecified dreams. It’s called Scratch and it’s meant to introduce children to computing by giving them easy, programmatic means to media manipulation.

The brilliant breakthrough has been to Lego-fy programming, making control blocks actually, well, blocks, and turning programming into block stacking. Yes, it’s messy and you have to fumble around for blocks but it’s visual, incredibly intuitive, and—get this—syntax error free (since blocks have shapes and will only fit in ways that make syntactic sense).

It was scary, you know, when I first knew about Scratch, just some days after it was launched, my evangelizing streak came back with a vengeance and I felt this strange calling to go and teach it somewhere, wherever. Here was finally an easy way to show “normal” people what programming was. Here it is.

The recent (April 16) revamping of TED.com around their famous talks provides the perfect excuse for me to finally write about them. And what I want to say boils down to one thing: watch them. They’re free. They’re one of the most exciting things content-wise to happen to the web of late. They have a cumulative effect. The audio and video quality are superb. They are raw, distilled passion. Their speakers are truly among the world’s most talented, most inspiring people (passion begets passion).

And if you only have time for one talk, let it be Eva Vertes’s—probably the best video I’ve seen, ever. Not only does she (very convincingly) puts forth a fascinating (and, oddly, satisfying) theory of cancer in less than 19 minutes, making it all seem as the simplest, most logical thing in the world, she also does it with a naive, youthful spunk that disarms you right away. I swear if I had seen this in high school I might have thrown it all away and study medicine. She’s that good. Now I’ll settle to try to convince my brilliant med-studying sister to tackle cancer. She too is that good.

Also not to be missed are…

Click, Shift-Click selections 2

Click somewhere in this post. Move the cursor somewhere else in it. Shift-click. Intermediate text is selected!

Just found out about this a couple of days ago. It’s always weird and somewhat shameful to learn so late something so basic but by the same token it is always oddly exhilarating. Seems to be particularly useful in cases where click-holding selection becomes unwieldy: when long fragments have to be selected or when a crappy touchpad is the selection tool. (Seems to work only on Windows so far. Seems to work on Windows and Mac so far.)

Wikipedia Popups 2

My Wikipedia investigations of late (I want to propose a major new feature and I’m feeling out the “deep” WIkipedia) uncovered the little known fact that as a registered user you can have a personal stylesheet and javascript file—which means that with a little know-how you can have Wikipedia looking and feeling exactly how you want it—and have this look-and-feel follow you around with your account. If you use the default skin, MonobookWP, your personal stylesheet and js file are monobook.css and monobook.js. There’s help here.

This opens the door to all sorts of customizing galore—skins, plugins, new features…—and while I still have to dig into it properly, so far I’ve found the amazing Navigation popups script, which pops up a small, smart (meaning it does interesting stuff depending on context) preview of any Wikipedia link you hover onto. Its slightly annoying until you get used to it, but once you do get it into your “work”-flow it’s very sweet—blazingly fast and with tons of handy extra options. Installing it is a snap too, just add one line to your monobook.js.

World of constraints, world of choices 2

Ultimately, the debate about choice is not about markets but about character. Liberty and responsibility really do go together; it’s not just a platitude. The more freedom we have to control our lives, the more responsibility we have for how they turn out. In a world of constraints, learning to be happy with what you’re given is a virtue. In a world of choices, virtue comes from learning to make commitments without regrets. And commitment, in turn, requires self-confidence and self-knowledge.
Virginia Postrel, Consumer Vertigo

Bloody good quote.

Why read The Economist 2

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.

The Economist, Flat prospects, Mar 15th 2007

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.

With only one recently acquired cellphone (that gets some ten phone calls per month) I probably should have heeded David Pogue’s advice and skipped his NYT’s article introducing a new phone service (not available, of course, here in Mexico) that consolidates all your phone numbers into one (new) number. Geekiness prevailed and I carried on. Happily, for it is indeed a “rather brilliant melding of cellphone and the Internet.” Number consolidation is only the beginning, there are some quite intriguing (and yet so simple!) services on top and along.

..Anyone who spends some time contemplating GrandCentral’s possibilities will soon see the bigger picture: this service removes your location as a consideration in phone calling, much the same way that the TiVo makes a TV show’s broadcast time unimportant. In other words, GrandCentral has rewritten the rules in the game of telephone.

Who would have thought? What with the iPhoneELZR, Samsung’s touch-screen that mimics the feeling of pressing a mechanical button, Dodgeball, mobile phone maps, and now this, the dowdy “tele”-phone is interesting again.
