Scratch Interface (!) 2

This may just be the coolest interface ever. I thought it was a joke when I first read about it: interact with computers through scratching your fingernail on surfaces. Simply amazing.

From the prolific interface genius that is Chris Harrison. Jump to 3:14 for the best concrete example of the technology in use: controlling your phone with gestures on a normal table with nothing but a stethoscope on it.

Computation at its root is distilled physics, interacting with our everyday physics it can produce pure magic. Think of accelerometers as well, or the now commonplace touch displays.

Enough is enough. As much as I love Twitter, they can’t seem to get their search act together. Try it right now, search in Twitter for something you tweeted about last week. Most likely outcome is you won’t find it, at all. It’s lost, buried, retrievable only through tiresome, trial-and-error paging. Google does scarcely a better job. How can this be?

The Husband: Isn’t that why people keep diaries? To be read by someone else? Otherwise why keep them?
Nagiko: To know about themselves.

HARPOON is a simple script to give you back your tweets. Install it and navigate to your Twitter user page,\twitter.com/YOUR-USER-NAME (or, for that matter, to anyone’s user page). You’ll see a new item in your sidebar, Harpoon! →

, from its UserScripts page. (You need to have the GreaseMonkey Firefox extension, version 0.8 or more, installed first.)

Backbars on social link-sites is a GreaseMonkey script to turn the headlines and comments of social link-sites into ambient bar charts (of votes/diggs/views/users…) It works on Reddit, Delicious, Digg, Hacker News, and Stack Overflow (and MetaFilter now!).

The idea is to give you subtle non-verbal clues to improve your browsing experience almost subconsciously. The backbars don’t replace the count they represent, what they do is convey you its magnitude unobtrusively, and, crucially, compare that magnitude to those around it. So you can now see, almost without thinking, that, say, some comment is popular, but that there’s a comment around that’s twice as popular.

Once you have it, just start browsing at your favorite social link-site: Reddit, Delicious, Digg, Hacker News, and Stack Overflow.




It’s the first release but it’s very usable already, I hope.

I hope you enjoy and find it useful, please let me know what you think of it in the comments.

An experiment in improving the reading interface of the world’s best news magazine. Very early days. Check it out at elzr.com/reader.

Right now it’s just a glorified table of contents but even that I think helpful. It includes the abstract of every article or it’s first line —in my experience The Economist’s pithy, playful titles can be under-descriptive. And there are also backbars behind every title, giving you an ambient, non-verbal hint to the article’s size. Both features are there to fix something that got lost in the transition from print to web.

I’ve read The Economist for many years now, almost since the beginning from the web (I subscribed for a year when it was behind a paywall, the only time I’ve paid for content). And almost as long, I’ve been struggling with it’s interface. I guess it’s not that bad for casual readers, but for longtime junkies it can be much improved. Which is what I’ll try to do in the coming days.

Changelog:
.3 version, 16 June 2009: BIG changes. See http://elzr.com/posts/03-release-of-the-economist-reader for full details. Read the whole magazine in a single page, columns, much better design (sections separators!), and… flags!


.12 version, 14 June 2009: Fixed
.11 version, 13 June 2009: Prettier version.


.1 version, 8 June 2009: Kicking it off.

Elegance & quantified selfhood 2

For a while now, I’ve been pleasantly following Very Small Array, an information design graph-blog, but this was the first time I was really enthralled by one of its designs, FRIENDS:



It’s just so stunningly elegant, isn’t it? So skillfully made to appear casual yet imbued with obvious formal beauty, charming yet minimalist—not a word or pixel unused. Labels and graph, typography and information design, come together marvelously, painstakingly.

The thing that most grabbed me, though, was that I had just started making my own similar introspective list of my friends’ attributes, in the spirit of quantified selfhood. While I’m floored by Very Small Array’s commitment (it has been doing this for almost a decade—the chart above is just one of several great graphs and metapgraphs), my brief exercise in self knowledge has already told me two unexpected things: I have a history of liking extroverts and polyglots.

I’m fascinated by meaningful compound words, the more elegant the better.

Esperanto is full of them, based on them really. Chinese writing is like that too, at times—I’m particularly impressed by things like 大å°?, literally “big”-”small”, used occasionally to mean “size”.

One problem that comes up is is that no matter how small the root words, compounds eventually get unwieldy, even to express simple ideas. In Esperanto, for instance, supr- is the root for “up” and you attach the -en directional root to make supren = “upwards”. Using the inverting root, mal, you get malsupren = “downwards”. So you end up having to say the clunky malsupreniri to express the simple “to go down” verb (iri = “go”).

One very elegant solution mentioned in Claude Piron’s wonderful La Bona Lingvo (“The Good Language”) is to take a different, simpler track altogether. The same idea of “going down” can be more elegantly expressed as desupri, literally “to from-top” (and the corresponding alsupri, literally “to to-top”). This, to me, is the stuff of beauty.

I recently learned 2 new Japanese words, fascinating to me because they used an entirely different conceptual track to the one I knew. You see, the Yamanote line is Tokyo’s most important train line and, remarkably, a loop. Japanese refer to trains travelling the loop clockwise as 外回り, literally "out"-"go around", and counter-clockwise as 内回り, literally "in"-"go-around". In Japan, trains, like all traffic, travels on the left and so these words make wonderfully creative, precise descriptions. (This is done, though rarely, in Western countries too, I later learned.)

The problem with these words is that they’re specific to Japan’s traffic regulations—they would confusingly mean the opposite in much of the right-driving rest of the world.

So, inspired by the Japanese track, I decided to create more universal words for clockwise and counter-clockwise, words which always confused me as a child and which aren’t particularly wieldy (in Spanish, the equivalents truly weigh you down: clockwise = “en el sentido de las manecillas del reloj, counter-clockwise = “en el sentido opuesto de las manecillas del reloj”). Fun historical note: clock hands move the way they do because that’s the way clocks’ predecessor, sundials, advance—sunwise that is (in the Northern hemisphere).

Thus I present to you rightcenter, meaning clockwise, as in “clock hands move rightcenter”, with the center to the right, in a right center way. As well as leftcenter, meaning counterclockwise, as in “screws are usually loosened leftcenter”, circling with the center to the left, in a left center way. Their derivation, I hope, is made even more obvious by the following diagram:

In Spanish, they can be translated into the much wieldier alternatives to the local counterparts: “con el centro a la derecha” and “con el centro a la izquierda”, respectively.

Now, I make no illusions that these terms are immediately or intuitively graspable—spatial direction is hard, most of us still have to consciously think about telling right from left. These words are just an alternative, fun way to label (and thus think) about the concepts of circular direction—and to think about language itself.

I've seen the future, thru a head-display! 2

We will all be wearing something like this in no more than 5 years. Seriously, it’s positively awesome, just look how silly happy I look.

Your brain is uncannily good at patching your vision so you can eerily “see thru” the screen—soon enough the feeling of obstruction disappears and it just floats magically along. The tiny screen is good enough for text to read and you can apparently browse the web too. You control it through some controls at the headphones. It’s already for sale at some very reasonable $700 here in Japan (online only). So Mannfred Macx!
Head-mounted displays are SO the future. Look how happy I am!
Oh and I just uploaded a massive 200 photo batch to Flickr, at the end of this set, starting with this picture. If you wonder why this blog has seen so little love lately, it’s because most of my online efforts have been directed to photoblogging—these aren’t just pictures, I title each one with a brief summary of what I was thinking when I shot it or what it makes me think. It’s a strange style but it suits me and I hope you like it (you’ll probably like it, just as for this blog, if you’re more into ideas and stuff than people). There will be much less photoblogging coming though, since I’m focusing all my energies on learning Japanese!
At Odaiba, beautiful, huh? I'll eat natto until I like it! This time, my 3rd, it was almost good! Got a new bike! Rusty but trusty! Electronic price signs! Funny how unimpressive the Tokyo Tower (that red Eiffel tower clone) was when we were standing by it. It is way taller than most buildings (and taller than the Eiffel tower). My lovely family back in Mexico, where the New Year came one day after. Video chatting is so awesome.I mean, isn't this grand? Dozing elders tenderly amuse me. They remind me of mom late at night, trying to carry a conversation but just babbling... :)

Korea, one-week impressions 2

Loved it! Far more than I expected, and almost as much as I love Japan, which is surprising because I’ve long been infatuated with Japan. Truth is I knew next to nothing about the whole country when I arrived.

Being tired from sightseeing we, my sister and I, decided to stay in Seoul the whole week and just try to get the feel of it. Well, it can feel even more urban, media drenched, faddish and dynamic than Tokyo at parts, and yet it is noticeably less wealthy and developed, and most of the city is, while new, astonishingly drab and nondescript.

First, the country’s cheap, all the more so with the exchange rate at that time (exchange rates are changing all the time these days). It’s quite more developed than Mexico yet somewhat cheaper. Compared to Japan is consistently half as cheap. (Though some girl in the hostel, returning from China, complained about how expensive everything was.)

People bump with you, like, all the time and pretty deliberately. While individually they are very friendly, out and about they can be quite rude. Coming from uber polite Japan, it’s pretty shocking. Also, people are far taller than in Japan and while girls are not so prim I think they’re generally cuter. Though plastic surgery is BIG in Korea, particularly one to make your eyes Western looking (“double eyelids” they call them) which, to be honest, does make Asian faces more Western-ly attractive.

I was worried about the food because one previous experience in San Francisco was quite atrocious. It turns out it just takes some getting used to and some introducing. At its best, say, Korean BBQ, it is absolutely delicious. Very agressive tastes, sweet, sour, salty and spicy jumbled all together. There are street stalls everywhere, very Mexico city like, and many of them sell cheap, awesome snacks.

As for technology, flat TVs are indeed everpresent and so are PC bangs (web cafes), full of surprisingly decent machines and cheap as dirt (less than a buck an hour). The mythical 100mb web was fast when you downloaded but quite unimpressive when you were browsing. Cell phones, like in Japan, are not that impressive, though the average cell phone is indeed high above America’s, the best of the Canadian/American crop, full-keyboard BlackBerries and the iPhone, seems in my opinion better than anything I’ve seen here on the streets and playing at phone showcases.

Most interesting of all was all the history and analysis I read. It was exhilarating arriving at a country and not knowing even how to say yes or no, thank you or please. Even more disconcerting was not knowing anything about the country other than that the south was a rising economic power while the north was on the Axis of Evil. So I plunged into several history and analysis books, The Koreans one of the best, and emerged a newly minted Korean buff. It was surprisingly enlightening, there’s nothing like being in the place to pique your curiosity and there’s nothing like being internally motivated for so much history and facts to start to make sense.

The simplest way to do the Turing boogie 2

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?
