One of the most "exciting" conference took place in town last week - The CanSecWest conference 2008 (the world's most advanced conference focusing on applied digital security) was held in Vancouver, B.C. Canada. And of course, the most exciting event in the conference would be the "PWN2OWN 2008" contest, where three laptop computers each equipped with Mac OSX 10.5.2, MS. Windows Vista Ultimate SP1, and Ubuntu 7.10 (linux) are put to the stand to some brilliant "hackers" to break. The first person succeed take the laptop he/she breaks plus a cash prize. Specific rules applies to each day of the contest, regulations will be gradually relaxed over time, but the cash prize is also shrinking while the clock is ticking...

The first day, under the strict condition that only the default OS could be targeted, no security breach reported among all three machines. The second day (Thursday, Mar 27th, 2008), stand applications like email clients, browsers were allowed to be targeted and guess who was the first to go? The brand new MacBook Air with OSX 10.5.2 went down due to an undisclosed Safari (the default web browser for Mac) flaw. The Windows Vista held one more day and went down on the third day (Friday, Mar 28th, 2008). On that day, the contest rule was even more relaxed where more "popular applications" can be installed on the laptops. Thanks to an previously unknown flaw in Adobe's Flash software, thus the Windows Vista fell...

The Sony Vaio laptop running Ubuntu remained "un-compromised" at the end of the conference. The MacBook Air winners collected $10,000 and the Vista breakers collected $5,000. What a nerve wracking event!

Talking about all the weird weathers around the world, Vancouver is getting a heavy snow (well, on UBC campus at the least) after the Easter holidays. I sincerely hope this has nothing to do with the global warming phenomena...



Too bad we don't have any Cherry Blossoms (Sakura)around Buchanan.

My colleague John Bratlien recently wrote a summary on wiki comparisons. With his permission, I am posting the comparison result here and hoping it will help those of you who have demands to deploy your own wiki servers. Our IT infrastructure (mainly PHP/MYSQL applications) limits the pool of candidates selected for the comparison:

Overview and Objective:
Arts ISIT requires a fully featured and user friendly wiki solution to support our faculty in their teaching. The wiki interface should be intuitive so that a lay person can use it without more than just a basic introduction. In addition, we want a wiki solution that is low maintenance (easy to install, configure, support and upgrade).

Comparison:
The following matrix is a comparison of some key features offered by well documented, widely deployed, leading open source wikis. The focus is on PHP based wikis with the exception MoinMoin.

Notes:
* via plugin
** some of these wikis have experimental and beta versions of WYSIWYG editors, not production ready

Summary:
Ideally our requirements, WYSIWYG editor, easy inclusion of multimedia and intuitive management of content and users, are supported out of the box. Features that are part of the core are more likely to be robust than features added through plugins, as well plugins require additional work for separate installation and configuration. Of these wikis,
MoinMoin comes closest to meeting our usability requirements and does so primarily using core functionality. The PHP based wikis do not offer a workable WYSIWYG editor, however, of the bunch, TikiWiki offers the best pseudo WYSIWYG editor.
Regardless, lack of a WYSIWYG editor continues to scare off most users and therefore wikis lacking one should be eliminated from contention.

With regard to support and documentation, all of these wikis are adequate as all have highly active user communities and are well supported (as open source projects go).

Other Systems to consider:
There are PHP based wikis with fully featured WYSIWYG editors such as telepark.wiki and Triki-Wiki. However, telepark.wiki is not free; it costs 149 Euros to purchase. Triki-Wiki, on the other hand, is free and looks very promising but it is developed and maintained by only one individual, not a community. In addition, it is not widely adopted which makes it a riskier option as it lacks the support and documentation of a widely adopted wiki.

I haven't had much time to post lately due to projects are piling up at work. One of them is a cross-institutional online course between UBC and University of Melbourne. The course provides students the opportunity for comparative inquiry of Indigenous experiences of colonization and the manifestations of that experience in the contemporary socio-cultural environment. Through the use of digital interactive technologies like Flash and Immersive 3D platforms, students will have the opportunity to engage in authentic learning. Compare to the past mixed-mode courses, this one is more challenging due to the aspect that many of the subject matter experts are in the remote places. We must rely on video conferencing and project management tools to pull things together. So far, the team members are pretty happy with Skype and Basecamp. There are many exciting modules in this course are under-development: Flash based games, 3D re-construction of residential school, collections of multimedia elements and much more. So, stay tuned...
