An Excerpt of Radio Lab's Morality Episode

By Stephen Downes - Stephen's Web. An Excerpt of Radio Lab's Morality Episode
Dave Pollard links to WNYC (I haven't listened to it yet) and enthuses, "Listen to Season One's program on Emergence -- about how self-managed groups do very, very well without leaders. Instead, they self-adopt models, consensually. Order materializing out of disorder, chaos. This is our job: To allow to emerge collective models of better ways to live and make a living, working collaboratively with those we love in conversation and community, and then allow them to be adopted." In a complex society it may be more important to learn how to work collaboratively with those we are indifferent to, but the overall point is correct: collaboration isn't about leading, it's about modeling.

What the Heck Is a PLE and Why Would I Want One?

By Stephen Downes - Stephen's Web. What the Heck Is a PLE and Why Would I Want One?
Presentation (slides and audio running about 10 minutes) by Alan J. Cann from the University of Leicester. Good overview of the concept. What I like is the contrast between the VLE and the PLE with an emphasis on the idea that the former is 'control' learning while the latter is 'free' learning. More...

Multi-Touch Whiteboard Under 100 Dollars - Using The Wii Remote

By Stephen Downes - Stephen's Web. Multi-Touch Whiteboard Under 100 Dollars - Using The Wii Remote
This is an absolutely stunning demonstration. Basically, Johnny Lee creates a sensor by attaching a tiny light to a pen shell, then uses the Wii remote (Wii-mote) to track the movments of the pen. This allows him to turn any surface - a wall, a desktop, a computer screen - into a fully interactive computer screen and writing tablet. Brilliant. Using two-such pens also creates a multi-touch tablet PC, which allows you to expand and rotate objects. Here is the link to the software - those of you who have Wii-motes, let's see what you can do with them. More...

WWW FAQs: Why Do My MP3 Files Sound Bad in Flash Player?

By Stephen Downes - Stephen's Web. WWW FAQs: Why Do My MP3 Files Sound Bad in Flash Player?
Good description of why some MP3s sound funny when played using Flash applications. Boutell says "Audacity and Flash don't always play nicely together," which isn't quite accurate. the reality is, Flash only plays certain types of MP3 files. "The problem is that Flash Player only supports two sampling rates: 22,050 samples per second, and 44,100 samples per second." Which is really stupid and something Adobe should fix. More...

An Educational Technology Dead End?

By Stephen Downes - Stephen's Web. An Educational Technology Dead End?
An instructor, following a disappointing experience with Sakai, wonders whether the LMS isn't a dead end. As a wise faculty member once said to me, 'Faculty only learn one or two new technologies every two or three years--and adding an attachment to e-mail counts as two of those.' Why not try to slip a single-system solution into their lives as a single technology? The answer may be that course management systems can just as easily stifle learning as enable it". More...

10 Semantic Apps to Watch

By Stephen Downes - Stephen's Web. 10 Semantic Apps to Watch
What gets me about these is not how neat and forward-thinking they are but rather how ordinary they are. That's not to say they are ordinary (I know, I know, bear with me...). What I mean is, all this semantic goodness is now so common-place, it's impossible to see any distinguishing features. Freebase, for example, wants to "open up the silos of data and the connections between them." Well who doesn't? I can name a dozen applications off the top of my head trying the same thing. Adaptive Blue "allows web site publishers to add semantically charged links to their site... 'in-page overlays'... popups." Well - so? We've got alt search engines, the ubiquitous travel planning app, and... and... None of it really speaks to me. More...

Only Connect...

By Stephen Downes - Stephen's Web. Only Connect...
This post rambles a bit but is probably worth a look for some thoughts - a restatement, for example, of the idea that knowing is essentially 'connecting' (which, in turn, to my mind, is pattern recognition - but I digress). There are also indistinct links to embodiment, affordances, and slow learning (a pretty obvious derivative of the whole 'slow food' movement). The strength of weak ties. In related news, I have edited and (slightly) revised my cornerstone essay on the subject, An Introduction to Connective Learning, which is now available an an MS-Word document. More...

Reflections On a DIY Streaming Experience

By Stephen Downes - Stephen's Web. Reflections On a DIY Streaming Experience
Video streaming in a multimedia environment is the new black. The solution we agreed on included the use of a basic Web-cam, a podcasting kit, two laptops (one for the streaming and one for Second Life - note that a very well spec'ed single laptop might have sufficed for both tasks but one wasn't available and using two felt like the safest option). I plan to do some of this sort of stuff while in Colombia next week, as well as from Malaysia in January. More...

PHP in Contrast To Perl

By Stephen Downes - Stephen's Web. PHP in Contrast To Perl
I have long resisted the temptation to join the crowd and work in PHP, even though today's most popular applications - things like WordPress and Drupal - are coded in the language. When discussing it, I am prone to grimacing and saying "spaghetti code". This post, which compares Perl (my language of choice) and PHP in exhaustive detail, explains why. Now yes, I know that the article glosses the miserable inconvenience of installing Perl modules. But I favor Perl, not simply because PHP requires 3079 functions to do the job Perl does with only 206, but because those functions are inconsistent eight ways over Sunday. More...

New LD Generation

By Stephen Downes - Stephen's Web. New LD Generation
Much more flexible user interface technologies are making it possible for a new wave of drag-and-drop learning design editors to be created. But while these tools may disguise the complexity of the specification, we can see the limitations more clearly as well. After all, after you've defined 'interactions' using 'discuss', 'explore' and 'inform' a few times, what do you do next. More...
