What If Every Child Had A Laptop?

By Stephen Downes - Stephen's Web. What If Every Child Had A Laptop?
The most important bit in this article - which focuses mostly on the competition between the One Laptop Per Child (OLPC) project and Intel's Classmate - is in the very last paragraph: "If you're wondering if the One Laptop will be available in the U.S., right now Negroponte's in talks with some states and school districts. He says it will be sold commercially in the future, but you'll have to buy two: one for your child and one for a child in a poor country". More...

Quote of the Day

By Stephen Downes - Stephen's Web. Quote of the Day
Trying to track this down leads you through a merry-go-round (people should link to actual posts, not merely home pages) so the link isn't really worth following (I found a much better link, here, about five hours later). But the thought is definitely worth echoing. "You can't figure this stuff out from the outside." Quentin D'Souza adds, "Never listen to a presenter or keynote that has not been immersed in the environment that they are talking about. You will be misinformed." That's a bit extreme. But people who are not immersed are much more likely to make mistakes about the environment. More...

Groups, Networks, Collectives

By Stephen Downes - Stephen's Web. Groups, Networks, Collectives
Scott Wilson joins the groups and networks discussion. He writes that he is not sure about the introduction of 'collectives' and that "there is a lack of clarity around the difference - very large, I'd say - between a network operating within a single managed service (such as an Elgg installation) and a network formed by people blogging and tagging things of mutual relevance." Of interest are his diagrams - "cybernetic modeling" of groups, distributed networks, and bounded networks. More...

Publisher Position On Author Rights

By Stephen Downes - Stephen's Web. Publisher Position On Author Rights
Peter Suber calls this recently released position paper "wishful thinking" and Im inclined to agree. The document stressed how important it is for publishers to own exclusive rights in order to manage the 'publication of record' and (more importantly) 'enforce' strictures against plagiarism. But mostly, the paper the paper is intended to present arguments against mandated public access for research funded with public money. More...

A Fair(Y) Use

By Stephen Downes - Stephen's Web. A Fair(Y) Use Tale
Video - consisting entirely of excerpts from Disney Cartoons - describing the principles of copyright and, most importantly, fair use. It is worth nothing that a video like this, while quite legal - the author is very careful to use only small snippets of Disney content, hence respecting fair use provisions - would be impossible under DRM, as these technologies are intended to prevent any copying, not just illegal copying. See al;so the video home page. More...

Do You Ubuntu?

By Stephen Downes - Stephen's Web. Do You Ubuntu?
The answer is yes. But if you want to know how I spent a good part of my long week-end, well let me tell you, the result of typing the command (as root) "cp thunderbird2.tar.gz /usr/lib/*" is to have your computer erase both thunderbird2.tar.gz as well as the entire contents of /usr/lib - the directory where all your applications are located. No recovering from that error; I had to reinstall Ubuntu. It takes very little time to install Ubuntu, true, once you have the disc. Longer to put your computer back the way it was. More...

Scores and Grades: Let'S All Pretend They'Re Rational and Helpful

By Stephen Downes - Stephen's Web. Scores and Grades: Let'S All Pretend They'Re Rational and Helpful
The author's point is that "We like to pretend that academic scores/grades are instructional and Pedagogical, but really they are motivational/game elements. The reason to work hard is to get a good score." Also, "We also like to pretend that scores are scientific, when instead they represent a staggering editorializing of what is important, and by how much." This is why quantifying my blog's success is ridiculous. It's not that you can't count anything about my blog. You can. But in so doing, you misrepresent the reason why I am creating the blog and misrepresenting what's important about it. The same for business blogs. If you are quantifying the blog's ROI, I content you have misunderstood the point of the blog and its value to your business - your desire to measure its effectiveness will ensure that you minimize it.

OpenID: Decentralised Single Sign-On for the Web

By Stephen Downes - Stephen's Web. OpenID: Decentralised Single Sign-On for the Web
OpenID is of use to educational applications because it allows for them to interact with the many Web 2.0 applications in wide use today. Many educational institutions adopted a federated approach - such as Shibboleth - which leaves identity management in the hands of the institutions (and which, pointedly, does not operate outside the federation, that is, not outside the institutions in question). I argued at the time that the federated approach was the wrong one, and the reason was that a distributed system such as OpenID would enable much greater interoperability. We are seeing the proof of that argument today. More...

Measuring Blog Success

By Stephen Downes - Stephen's Web. Measuring Blog Success
My post yesterday on measuring your blog's success had generated some reaction, from the comments to Tony Karrer to Beth Kanter, who says I "missed the point' - "Whether you want to make money or educate people or just deepened your own learning -- setting some realistic benchmarks or goals, figuring out a way to determine if you reached them, and reflecting on why or why not - can lead to continuous improvements in the quality of your blog writing." One of my posts from earlier today constitutes part of a response - but also I want to point to Karrer's reasons for blogging - personal learning and network building. My point is that there is no quantitative indicator of successful personal learning or of a valuable network contact, and that any attempt at such will misrepresent what it is we actually value in learning or network contacts.
