Cornrow fractals

Complex mathematical concepts are difficult to teach, so textbooks frequently try to explain things by referring to everyday phenomenon. But textbooks are often pretty culturally specific, so it's hard to translate them from one country to another -- or even from one cultural group to another. A textbook written using farm examples from rural Idaho ain't gonna cut it with kids in New York who've never even seen a tree, and vice versa. So the trick is to find relevant culture that also represents high-end math. Such as ... cornrow hair braids. Some educators realized that cornrows were a great example of fractal geometry, and developed some software that illustrates how it works. Ron Eglash of the Rensselaer Polytechnic Institute wrote about it on his web site: Each braid is represented as multiple copies of a "Y" shaped plait. In each iteration, the plait is copied, and a transformation is applied. The series of transformed copies creates the braid. In the above example, we can see the original style at top right, and a series of braid simulations, each composed of plait copies that are successively scaled down, rotated, and translated (reflection is only applied to whole braids, as in the case where one side of the head is a mirror image of the other). One of the interesting research outcomes was that our students discovered which parameters need to remain the same and which would be changed in order to produce the entire series of braids (that is, how to iterate the iterations). (Thanks to Yishay Mor for this one!)

Q&A with Wendy Seltzer Regarding NBC Universal's Request to YouTube to remove NBC material from its site

Yesterday's New York Times reports that NBC Universal asked YouTube, a free video-sharing site, to "remove about 500 clips of NBC material from its site or face legal action under the Digital Millenium Copyright Act."  NBC's request followed the soaring popularity and frenzied cross-posting of "Lazy Sunday," a rap video featuring Saturday Night Live comedians Chris Parnell and Andy Samberg.  "Lazy Sunday" is currently available on two sites -- it is free on NBCs site and costs $1.99 on Apple iTunes.  From the article:

Julie Summersgill, a spokeswoman for NBC Universal, said the company meant no ill will toward fan sites but wanted to protect its copyrights. "We're taking a long and careful look at how to protect our content," she said.  

We asked Berkman Fellow Wendy Seltzer (founder of the Chilling Effects Clearinghouse, former staff attorney with the Electronic Frontier Foundation, and now a Visiting Assistant Professor at Brooklyn Law School) some questions about this issue:

Question: Wendy, you blogged this morning that, "I'm sure NBC lawyers need no reminding that unlike trademarks, copyrights do not need to be policed to retain their validity."  Could you explain why copyrights do not need to be policed in order to retain their validity?
Wendy:
Sure, the confusion often comes about because copyright and trademark are two very different kinds of protection, sometimes lumped together as "intellectual property."  Copyright is the author's right to prevent unauthorized reproduction or public performance of a work (among other rights).  It can be exercised at any time, and is not abandoned by a lack of enforcement.  That means copyright holders are free to pick and choose their targets, to stop only those whose appropriation is causing them harm.
Trademark, by contrast, is the right to protect a brand as a source-identifier.  If a trademark holder let others use the mark for commercial identification, so "Saturday Night Live" was no longer associated with NBC's show but with any Saturday night TV, it would no longer serve that function.  (In practice, very few trademarks are lost to abandonment or genericide either).  

Question: If that's how copyrights are protected, how should copyright holders respond to situations like these?
Wendy: The first question should always be: "Is this hurting us?" and the second, perhaps, "will publicity around a takedown demand hurt us more?" (see Chilling Effects for examples).  If a copying isn't hurting the copyright holder, there's no reason to stop it.  If it starts to hurt, you can always object later.  (The overly cautious lawyer might send a letter saying the current activity was authorized under a temporary, revocable license.)

Question: You comment that NBC "seems to be shutting down its own best advertising."  Why is this the "best" form of advertising for NBC?
Wendy: In this case, it seemed the video's circulation online was driving more people to watch SNL on television, (and likely encouraging them to watch it live so they could have the first crack at talking about new episodes with friends) -- attracting viewers especially among the young, connected demographic advertisers want to reach.  People were making websites, t-shirts, and remixes, and all were helping to build an audience for whatever the Lonely Island team did next.  Now, searches on "Lazy Sunday" turn up references to the takedown well ahead of NBC's site.

Question: What does this tell us about tomorrow's world of advertising? What are the rule set changes?
Wendy: Media today are competing for attention.  While it may be hard to predict what will attract attention, savvy marketers should embrace it when they find it.  NBC could have asked YouTube for an acknowledgement and link to NBC's website, for example, if they wanted to bring people back to the network's pages and tie the video to the television experience.

Malcolm Gladwell profiled

gladwell.jpgSunday’s Observer featured an in-depth profile by Rachel Donadio of Malcolm Gladwell, author of The Tipping Point and Blink.

“With a writerly verve and strong narrative powers, he leavens serious social science research with zany characters and pithy, easily digestible anecdotes.”

Gladwell’s publishing success – Tipping Point has sold 1.7 million copies in N. America and Blink has sold 1.3 million – has led to a lucrative career as a public speaker for which he is apparently now paid about $40,000 per lecture. On top of that he’s also a columnist at the New Yorker.

“Gladwell’s dazzling arguments ultimately offer reassurance. Indeed he seems a contemporary incarnation of a recurring figure in the American experience, one who comes with encouraging news: you can make a difference, you have the capacity to change.”

Update: Malcolm Gladwell has a blog; via Marginal Revolution.

Oh, what a year

One year ago today, I asked the readers of kottke.org to become micropatrons and support my efforts in producing the site for a year. Over the course of three weeks, people generously sent in their financial support[1], giving me enough to pay my salary for the entire year[2] and not have to bug you about it every few days.

So the year is up and I've been trying to think about what to say on this occasion for, oh, about six months now, but I'm undecided even now. I guess I'll start with the important bit.

I'm not going to be asking for contributions again. Part of it has to do with the reasons outlined at the bottom of this post. I haven't grown traffic enough or developed a sufficient cult of personality to make the subscription model a sustainable one for kottke.org...those things just aren't interesting to me.

The other big reason is that my life has changed a lot in the past year. Growing a new business with a novel (or at least challenging) business model requires lots of time and energy to build the necessary momentum...basically approaching it with a startup mentality: long hours, work on the weekends, less time to spend with family and friends, making work the #1 priority, etc. My (unstated) intention from the beginning was to approach the site as a startup, but along the way life intervened (in a good way) and I couldn't focus on it as much as I wanted to. The site became a normal job, a 9-to-5 affair, which meant that I could keep up with it, but growth was hard to come by.

So what's going to happen with kottke.org? I'm not quite sure at this point. In the short term, it's going to be taking a back seat to some other things going on in my life. Longer term, who knows? I might look for other ways to fund my efforts on the site or maybe it goes back to being more of a hobby. But there will be posts and links and other things here almost daily, just like there have been for almost 8 years now.

And that leaves approximately everything else, if anything, unsaid. If you're curious about something related to the end of the micropatron experiment, send me an email with your question. I'll choose the most interesting and/or representative ones and post my responses to them in a future entry. I'll give special consideration to questions from micropatrons. Or post your thoughts to your blog, send me a link, and I'll compile those as well. And as always, your feedback is appreciated via email. (And sorry in advance if I can't respond to your questions individually, although I'll try my best.)

[1] Again, thanks to everyone who contributed for their support. In this age of ad-supported media, it means a great deal to me that you felt strongly enough about kottke.org to support it directly. I'd also like to thank Eyebeam, the companies and people who contributed the fund drive gifts, thelist, Jonah, and Meg for their help and support.

[2] Since everyone and their uncle has been asking, about 1450 micropatrons contributed $39,900 over the past year...99.9% of that coming during the 3 week fund drive.

Devices in dialog

In this photo, two cellphone screens contain two halves of a single word / phrase (”I LO / VE U”) - a digital friendship charm between sisters.

This didn’t require special software, and the phones aren’t linked as in a multi-monitor desktop - each phone is simply using a related graphic as its wallpaper. However, as we see in the real and imagined screen interfaces of the future, harmonized or sympathetic devices are becoming a big deal - small devices, loosely joined. In addition to various forms of smart mobs, loosely linked digital accessories are entering the arts in examples as disparate as pervasive gaming and proximity response fashion accessories. SMS, Bluetooth, and RFID tags are the common channels of communication for devices that don’t just shake hands, or pretend to speak, but enter into actual dialog.

This dialog might occur coorperatively, like TileToy, or synergistically, like Furbies… or even antagonistically, like Needies. The interactions of most digital toys seem to be modeled on either pet play dates or else Balanese cock fights, however. Even when the topic system is extremely complex, the result resembles chatter more than dialog.

There have been some interesting (and humorous) experiments with connecting two chatbots so that they talk to each other. What would happen if we carried chatbots around inside our digital devices? It might be interesting if our virtual pets gradually evolved towards becaming dramatis personae. Then I could bring my “Grace” cellphone program - and you could bring your “Tripp” action figure…

…and when Trip said “I love you,” Grace might respond “Just saying that doesn’t make everything better.” Tripp says “What have I done now?” and we’re off.

Browse carefully: a critical Safari vulnerability

Over at Secunia, they're reporting that the "Open 'safe' files after downloading" feature in Safari has a nasty downside as shell scripts can be executed via single clicks.

They've built a test which opens Calculator and, yep, it's exploitable. For Safari 1.3 and well as 2.0.

It might be a good idea to just turn off the "safe files" download feature (in the Preferences menu) until a patch is released by Apple.
