Modified Preorder Tree Traversal

Modified Preorder Tree Traversal
Luc Belliveau, who works with us as a resident computer wizard, showed me this today. It's the neatest thing - a simple way to generate a list of the parent branches in a tree from XML data stored in a normal database. More...

Australia Bound

Australia Bound
It has taken a lot of planning by many people, but next Monday I will jump on to an airplane and fly around the world. On the way, I will stop for a month in Australia, visiting (in order) Canberra, Brisbane, Cairns, Darwin, Alice Springs, Adelaide, Hobart, Sydney and Perth. I will be giving public talks in most of those locations. This link describes the talks I will be giving and some additional details about my trip. If you are living in Australia (and a great many OLDaily readers are) then I hope to be able to see you en route. By Stephen Downes, Stephen's Web, September 8, 2004 [Refer][Research][Reflect].

iSociety

iSociety
This is a pretty good essay. I haven't read it completely but I've read enough to know that it's worth passing along. An analysis of the use of internet technologies to support social networks, it looks at things like the importance of reputation, limits on the size of networks people can support, and some dangers of social networking such as isolationism and cronyism.

This is a great article and a must-read for anyone who designs web pages. The study is based on measurements of readers' eyes as they look at news websites. Some results we've seen before in other studies: pictures are 'lighter' on the web than in print (that is, they don't immediately attract the eyes); shorter paragraphs are read more; text ads work better than banners.

New Students, New Learning

New Students, New Learning
Greetings from Canberra. This issue of OLDaily is a little short, but having landed just yesterday and given a longish presentation today, I'm dead tired. This item is the slides from the presentation - originally intended to be two separate talks, one on e-learning quality, one on the new student, but mixed and mashed into one quite long presentation. I have audio, but rather than inflict 130 megabytes of download on you, will try to get it compressed first. Meanwhile, enjoy the slides. Readings associated with the talks may be found on my wiki, here and here - feel free to add your own resources or comments.

Thoughts on Stephen Downes’ ITI Keynote

Thoughts on Stephen Downes’ ITI Keynote
More on my presentation in Utah. D'Arcy Norman picks out some good bits (not necessarily the bits I would have picked - but that's why commentary is so interesting). Here are the links to the Apollo and Pachyderm projects he mentions. I don't think they're it, but we need to talk about it more. More...

Downes Wiki

Downes Wiki
I have added a wiki to my website. As I write, it's still mostly empty. But it adds for me something my website has been badly missing - a scratch pad, where I can jot down ideas. I'm going to use it in the short term to plan my talks for my trip to Australia (you should feel free to add your thoughts and ideas). Longer term, who knows? The software I used is called berliOS:ErfurtWiki. This is not an endorsement - It didn't install cleanly and I had to rewrite some code myself to make it work. That said, now that it works, I really like it. A lot. The page design formatting is still a bit off, but that will be improved over time.
Speaking of Australia - I leave for Canberra on Monday. I will try to get a Daily issue out on Monday, but no guarantees. There will be no issue Tuesday. After that, there may be additional disruptions, depending on internet access. Readers of OLWeekly should not expect any major disruptions (and I'll get the newsletter title fixed as soon as I can).

College Backs Off Wi-Fi Ban

College Backs Off Wi-Fi Ban
A sign of the times - the students' own personal Wi-Fi networks were (supposedly) interfering with the university-run system, so the administrators' first reaction was to ban the student systems. Turns out, though, that they may not have the authority to do so. More...

Go Fast. Go Cheap. And Let It Go Out of Control

Go Fast. Go Cheap. And Let It Go Out of Control
Brian Lamb's presentation at the ITI conference in Utah in the form of a set of Wiki pages. There's a lot of content here surveying new technologies in learning, including blogs, wikis and RSS - hard to believe he got through most of it in his session. More...
