How about if there were a magical shape we could draw on top of a slide that would magnify what’s under it? So, if you were showing a slide of a screen capture, you could invoke these shapes to come and go, enlarging the elements to which you want to call attention.

kthxbye.*

Yes, not an entirely appropriate use of the term, but I find it an amusing youthicism. Its marginal appropriateness in this case is that I’m acknowledging that I’m talking into the wind when it comes to making product enhancement suggestions. And, yes, now the footnote is longer than the post. kthxbye.

The latest Radio Berkman podcast is with David Hornik of August Capital. David is delightful — not always the term applied to VCs — and finds some reasons for optimism in the current darkling gloom. [Tags: berkman podcasts radio_berkman david_hornik vcs recession innovation ]

Me, on Twitter:

Challenge: Explain Fourier Transforms, w/o math, to a Humanities major (me), more clearly than http://tinyurl.com/27n3g … in 1 tweet?

Note: I somehow got the TinyURL, which points to the Wikipedia article, wrong. The Wikipedia article begins this way: “In mathematics, the Fourier transform is an operation that transforms one complex-valued function of a real variable into another.” It does not get clearer after that, at least for this Humanities major.

The responses, in the order received:

jonathanweber Looking at a periodic signal in time, the Fourier transform explains it in terms of what mix of frequencies is present. Helps?

DarrylParker the better question is why does a humanities major like you need to understand it? ;)

cparasat It’s just adding waves to other waves.

DarrylParker simpler overview of the Fourier series, but still a bit mathematical – http://tinyurl.com/chw5pp

fantomplanet Fourier Xformations are like ironing your shirt. It smooths things out.

JoeAndrieu FTs take a signal in time and represent it as a series of frequencies. Makes audio signal look like an equalizer graph.v

ts_eliot in 1 tweet?! impossible

fanf the FT splits a signal into separate frequencies, like a prism splits light

fjania – it shows us which, and how much of each, simple sine waves we can add together to reconstruct the signal we’re transforming.

ricklevine Hm. Fourier transforms convert a bunch of sample measurements (audio, seismic data, etc) into frequency info: http://is.gd/iQP3

ricklevine Of course there’s a lot more to it. Try: it’s a way of taking seemingly rndm data and fitting a curve to it, enabling analysis.

fields Things you don’t understand can be expressed in smaller equivalent pieces of things you don’t understand.

IanYorston “Explain Fourier Transforms to a Humanities major”. Smart maths breaks large constructs down into small things loosely joined.

mtobis: your tinyurl fails. Fourier transform an audio signal and get back an amplitude for each pure tone; no information is lost.

vasusrini Sound=Vibrating Air.Bee Buzz & dog bark=diff. frequency signatures. Ear hears all at once & sorts it. FT is the m/c equivalent.

chichiri just say without it you wouldn’t have JPEGs, enough said ;)

artficlinanity Every signal, no matter how complex, is made up of simple sinusoids. Fourier Transformation is how you find those.

vnitin every physical phenomenon can be viewed as existing in space+time or vibrations+energy. FourierTrfm converts view1 -> view2

_eon_ think of waves on the ocean

I’m on a mailing list for former employees of a company, and we’ve been on a track for a day talking about what computer is best for aging parents or grandparents who want to do email and some basic Web browsing. This is from the point of view of the people who are going to be doing support and sysadmin for their relatives.

For years I’ve casually tried to get various folks interested in creating an OS shell or skin specifically designed for the elderly who are unfamiliar with computers. The existing OSes do things like put icons on desktops that are then covered by windows. Yes, the Mac’s Dock helps. And obviously the elderly can learn how to use computers, just as we all have. But the hurdle is unnecessarily high for people who have never held a mouse before.

So, my questions:

1. Is there such an operating system shell or skin?

2. Is there a wiki so we can at least share our experiences providing computers and support to our elderly relatives?

Can you spot the most important difference?

Here’s a well-known photo of the original, extant Kindle:

Here’s a photo from MobileRead that purports to be of the soon-to-be-announced Kindle 2.

If you said that the Kindle 2 can be held without inadvertently pressing buttons, you win!!!

Urs Gasser has officially been announced as the new executive director of the Berkman Center.

This is excellent news. Urs has been a fellow at the Center, as well as the head of an Internet research center in Switzerland. There’s thus no period of wondering if he shares our values, what do we think of him, etc. We know his, values and many of us have already had the pleasure of working with him and learning from him. Urs, in a word or two, is completely at home in the Berkman’s admirable ethos of smarts and kindness. I’m very, very happy that Urs has taken up this role. [Disclosure: Yes, Urs is in some sense my boss. But that’s not really how the Center runs.]

Urs steps into the Bunyon-esque shows left by John Palfrey, who remains a faculty co-director but is now Vice Dean of Library and Information Resources at Harvard Law. Colin Maclay, managing director of the Center — so smart, so kind — served in the interregnum.

You can hear an interview with Urs (by, um, me) as part of the continuing Radio Berkman podcast series…

Wendy Seltzer has a screen capture that proves that Google is harmful to the Internet.

This is a reference to the 40-minute Google outage a couple of days ago. More about StopBadware here. And here’s an example of a site Google lists as malware.

… in the dark, threatening, and one-sided.

Thus, the RIAA is appealing the decision to let a hearing in its suit against a file sharer — Joel Tennenbaum — be webcast.

The Electronic Frontier Foundation (did you remember to join?) has filed a brief in support of webcasting the hearing, in which it says:

“The record companies have long maintained that they brought these lawsuits against ordinary users to start a national conversation about peer-to-peer file-sharing,” said EFF Legal Director Cindy Cohn. “What better way is there for the public to learn what the record companies are doing than by seeing for themselves what happens in these lawsuits?”

I’d like to be able to jump to a date in Google Calendar by typing in a date, because paging through 15 months takes precious seconds that could otherwise be spent in scratching myself. I was hoping that typing a date into the search field would work, but it doesn’t. In fact, searching for something like “5/8/08” gives results that seem random but undoubtedly have an inner but unhelpful logic.

danah boyd has posted her doctoral dissertation online. Here is the abstract. (I haven’t yet read the dissertation, but I’m pretty confident it’s great.)

“Taken Out of Context: American Teen Sociality in Networked Publics”

Abstract: As social network sites like MySpace and Facebook emerged, American teenagers began adopting them as spaces to mark identity and socialize with peers. Teens leveraged these sites for a wide array of everyday social practices – gossiping, flirting, joking around, sharing information, and simply hanging out. While social network sites were predominantly used by teens as a peer-based social outlet, the unchartered nature of these sites generated fear among adults. This dissertation documents my 2.5-year ethnographic study of American teens’ engagement with social network sites and the ways in which their participation supported and complicated three practices – self-presentation, peer sociality, and negotiating adult society.

My analysis centers on how social network sites can be understood as networked publics which are simultaneously (1) the space constructed through networked technologies and (2) the imagined community that emerges as a result of the intersection of people, technology, and practice. Networked publics support many of the same practices as unmediated publics, but their structural differences often inflect practices in unique ways. Four properties – persistence, searchability, replicability, and scalability – and three dynamics – invisible audiences, collapsed contexts, and the blurring of public and private – are examined and woven throughout the discussion.

While teenagers primarily leverage social network sites to engage in common practices, the properties of these sites configured their practices and teens were forced to contend with the resultant dynamics. Often, in doing so, they reworked the technology for their purposes. As teenagers learned to navigate social network sites, they developed potent strategies for managing the complexities of and social awkwardness incurred by these sites. Their strategies reveal how new forms of social media are incorporated into everyday life, complicating some practices and reinforcing others. New technologies reshape public life, but teens’ engagement also reconfigures the technology itself.
