Another Thought Experiment


Another Thought Experiment 01/16/2004 01:04 PM

Mark Pilgram expresses his concerns about how some aggregators plan to handle invalid Atom feeds. Mark believes that rejecting invalid XML on the client side is a bad idea, and proposes a thought experiment in which all web browsers use strict XML parsers and refuse to display XHTML that isn't well-formed.

This is a bit of a bait-and-switch, though. XHTML has the whole sordid history of HTML on its back, and since browsers have generally been forgiving of even the most convoluted HTML there's a substantial backwards-compatibility issue. The XML-based Atom, however, is brand-spanking new, so it doesn't have the same baggage as XHTML.

So, let's try another thought experiment. I've copied Mark's Atom newsfeed and made it invalid XML by adding a single & character, then uploaded it to my site:

http://www.bradsoft.c om/feeds/badatom.xml

Mark asks us to "imagine that all web browsers use strict XML parsers," but rather than use our imaginations, lets see what happens when we browse this feed in Internet Explorer:

Hmmm...IE appears to be doing client-side validation, and it shows an error instead of displaying the feed's contents. Okay, so let's try Mozilla:

Looks like Mozilla does the same thing. How about Opera?

So, the most popular Windows browsers all perform client-side validation, and fail to display the contents of the invalid Atom feed. There's nothing surprising here, of course - any validating XML parser will reject this feed.

Consumers of RSS feeds have had to code around all sorts of validation problems in order to be backwards-compatible with existing feeds. Atom, however, is new, so customers aren't already subscribed to hundreds of invalid Atom feeds. Being well-formed is a requirement of XML, and Atom is defined as an XML format, so why not expect Atom feeds to be well-formed? Let's get it right this time.

Okay, everybody out there in blogland, here's an open invitation to post whatever the hell you want in the comments thread of *THIS* particular entry. The ONLY requirement is that you post as ME. So, use *MY* name (Chris Pirillo), *MY* e-mail address (chris@pirillo.com), and *MY* blog address (which, in case you're too to have noticed, is http://chris.pirillo.com/). At the end of the day, everybody has to guess who the *REAL* Chris Pirillo is. So, go ahead - post as "me," and then guess who "I" am. All non-me comments will be deleted and banned permanently, so play by the rules or GTFO. This experiment is only valid for this entry....

The File Sharing Experiment


The File Sharing Experiment 08/05/2004 12:38 PM

The File Sharing Experiment is a project with the goal of demonstrating how file sharing actually helps the music, movie, and software industry. Folks are encouraged to post purchases they've made and a short explanation of how they learned about the band/movie/game and why they ended up buying something for it. All the evidence is anectdotal, but when taken together, it's already over a quarter million dollars in reported sales and the site has been up for one week.

Personally, this was the point I tried to make in the heyday of Napster. You could find anything on Napster, but rarely could you find complete albums, so the service had the effect of promoting CD sales. I would often surf others' music lists whenever I noticed things I liked, download the things I hadn't ever heard of, then I'd end up buying CDs from Amazon.

OpenCourseWare in worldwide use and
experiment
03/13/2003 10:16 AM

MIT 's recently released OpenCourseWare ( OCW ) is being used by people around the world , who are putting its materials to different uses.

Mr. Cooper, who describes himself as "a lowly tech-ed guy" at Pacific University, in Oregon, says that he envisions a future in which professors and students, using free course materials like MIT's and open-classroom sites on the Web like Tapped In, will exchange their teaching services through a kind of online barter system.
"I could volunteer my hours [to teach] at the high-school level and that would give me credit to then get other hours from somebody else," says Mr. Cooper, an education-technology specialist at Pacific.
... At a Unesco forum about the project in Paris in July, Alain Senteni, director of the Virtual Center for Innovative Learning Technologies, at the University of Mauritius, said his institution had an interest in translating and adapting the content of MIT courses for French-speaking developing countries.
And Mohammed Dahbi, a professor at Mohammed V University's Agdal campus, in Morocco, said faculty members and administrators might use OpenCourseWare as a model for course structure and pedagogy when they recast their courses during the next few years. University courses, he said, are being rewritten as part of a broad reform movement in Morocco.
The high-profile, positive reception of OCW has prompted other institutions to pursue similar initiatives of Webbing up course content for world usage.

Portsmouth's Free Experiment Expands


Portsmouth's Free Experiment Expands 05/27/2004 03:17 PM
Portsmouth, New Hampshire, expands a one-year trial of free Wi-Fi in its downtown: I first heard about this on the radio program I was interviewed on yesterday on New Hampshire Public Radio (show archived at this page). The first year had 600 unique users connect to a free hotspot in the Market Square area. They're extending that and hoping for twice the users using donated services and hardware. The cost must be quite minimal. Now 600 people (not 600 sessions) only translates into an extra few people a day, on average, but Portsmouth is using whatever tools they have to increase traffic to the community. The fellow interviewed alongside me on the radio said that their big time is cyclical, every four years, when the primaries roll through the state, and that reporters were filing over the free Wi-Fi this last winter....

Stanley Milgram, famous for his six degrees of separation experiment, is also famous for his obedience experiment.  A variation of that experiment at Stanford, called Stanford Prison Experiment (google) is very relevant to what is going on today in Iraq prisons.  It shows where the cutting edge of the blade called Human Nature is so, hopefully, we can sheath it as best as we can.

Newspaper's Election Blog-by-Readers
Experiment
07/08/2004 10:15 PM
My colleague Mike Bazeley alerts me that the Seattle Times has announced an "Election 2004 Backyard Blog project," inviting readers to be part of the journalism process. The newspaper asks:
"Are you interested in this year's elections? Know your community? Like to talk politics with your friends, colleagues and neighbors? Want an opportunity to blog about your observations? "Apply to join a grass-roots campaign coverage effort by The Seattle Times. We want fresh thoughts and perspectives about the elections from places and people not often found in newspapers — your neighbors, your favorite cafes and other local hangouts."
The Times will keep control of the material submitted, exercising its editorial authority. I wonder what would happen if the paper just gave folks their own blogs and let things rip. Whether the control is too firm or not, this is an experiment to watch.
