McLuhan'S Laws of Media and the PLE

By Stephen Downes - Stephen's Web. McLuhan'S Laws of Media and the PLE
When confronted with new media, McLuhan said, ask these simple questions: what does it enhance? What dos it obsolete? What does it retrieve? What does it reverse? If you have an answer to these, well, as Terry Anderson argues, "This brief mapping of PLEs to McLuhan's Laws of Media illustrates that PLEs constitute a new educational media. More importantly, noting the inherent adherence to McLuhan's four laws helps us understand how best to exploit this technology and what to be on guard against as the PLE cycles through exhibition of all four Laws of Media." Via George Siemens, who says it sort of does and sort of doesn't. More...

The Importance of Learning Slowly

By Stephen Downes - Stephen's Web. The Importance of Learning Slowly
This is expressed a bit differently than usual, but it works: "Like neural networks, the brain is based on vector algebra, rather than numerical computations. Vectors have strength and direction, and many vectors, representing multiple inputs, unite to form a result. The result in the brain is strengthening or weakening of a set of neural connections, a relatively slow process. While a single event can have an impact, it usually takes many events to have a relatively permanent change in the brain (aka "learning") and to extract general features and generate rules from experience." Right. More...

Google to Host Atom Publication Protocol Plugfest

By Stephen Downes - Stephen's Web. Google to Host Atom Publication Protocol Plugfest
This is a bit odd, because my experience is that Blogger isn't really supporting the Atom API (the old Blogger is, but the new Blogger isn't). Here's my experience. And from that experience, I can say it would be nice if we had working libraries. More...

A Conversation at MIT

By Stephen Downes - Stephen's Web. A Conversation at MIT
I spent the day today at MIT where, thanks to the generous welcome offered by Phil Long, I visited OCW and the Media Lab, among other things, and engaged in this conversation with a number of the people at the University. I began describing the properties of successful networks, and from there we wandered through Edu_RSS, topics, tagging, resource profiles and more. I really enjoyed my visit today and, on listening again to the recording, think you'll enjoy this recording. The link is to the MP3 file. Stephen Downes, Stephen's Web April 10, 2007 [Link] [Tags: Edu_RSS, RSS, Networks]. More...

Coming Soon to a Desktop Near You: Massive Amounts of 3D for the Masses

By Stephen Downes - Stephen's Web. Coming Soon to a Desktop Near You: Massive Amounts of 3D for the Masses
I have seen both 3D scanning and 3D printing for myself in the National Research Council labs - this was almost five years ago so they must be getting at least a little closer to commercial application. It's a bit of a leap from that to desktop manufacturing, though, as this would require either that we stock every element in our printer (in addition to smelting capacities) or acquire some sort of transmutation capacity, which would be much bigger news than desktop manufacturing.

My Personal Learning Environment

By Stephen Downes - Stephen's Web. My Personal Learning Environment
Interesting post not only touting the concept of the personal learning environment (PLE) but also describing how hers is built from existing applications. Good stuff. Via Brent Schlenker. Related: Clive Shepherd summarizes my talk on PLEs at the eLearning Guild conference in Boston. Also, Stephen Powell on the talk. What I am trying to describe is more than just an aggregation of current desktop apps - it's a bit like the digital lifestyle aggregator described by Marc Canter, but I don't seem to be able to convey what happens when all the parts are actually linked together.

PodcampNYC Webcast Coverage

By Stephen Downes - Stephen's Web. PodcampNYC Webcast Coverage
Podcamp is one of those places I'd love to be but which is just far enough outside my range of expertise I can't make a case for going (especially when it conflicts with something else). But I enjoyed listening to the interview with Gary Leland of PodcastPickle.com. The audio and video content just works perfectly on the Mac, of course - I think I would be more inclined to multimedia if I used it all the time. More...

Standardising the Widgets

By Stephen Downes - Stephen's Web. Standardising the Widgets
Scott Wilson points to this interesting page from the W3C about standardizing for widgets (a widget is a stand-alone application you can embed in other applications, like a website or a desktop, or view on its own on a PDA). Quite a bit of the widget standard exists already - things like Javascript (aka ECMAScript) and the Document Object Model (DOM). W3C wants to add things like a manifest, packaging format, and widget API. More...

Competing For Attention

By Stephen Downes - Stephen's Web. Competing For Attention
Graham Wegner ponders the dynamics of blog readership, as he notes that it becomes harder and harder for new bloggers to become recognized (funny that he harkens all the way back to 2005 as the beginning). This is why I argue we should not be reading people, we should be reading topics. Reading people perpetuates this celebrity culture, giving an undue advantage to the first people in (or those with the loudest self-promotion). Reading topics allows anyone with something to say an equal chance for attention on any given day. More...

Why I'll Never Sign Up for Any Blogger Code of Conduct

By Stephen Downes - Stephen's Web. Why I'll Never Sign Up for Any Blogger Code of Conduct
Why is it that any time some problem occurs, somebody wants to make a rule. That sort of response is legion in organizations (especially mine). But the thing is, it never works - it is an attempt to respond with simplicity to what is inherently a complex problem. Sheesh, even spam filtering requires Baysean filtering, and that's a logic that is well beyond the scope of any code of conduct. As Dave Taylor says, "I don't want to pin anything down because I want to retain editorial flexibility." Right. Good behaviour isn't defined by rules, it is limited by them. Or as I commented on Clarence Fisher's blog, if you behave decently, you will already follow something like a code of conduct (but intelligently, adapting to complex circumstances), and the code won't change your behaviour. If you don't behave decently, then the code of conduct isn't going to stop you, and rather just gives you 'the letter of the law' as a technicality to duck behind if someone calls you on it ("well, it wasn't in the code, so I assumed it was OK...").
