Data Points on Tim Bray’s Keynote at CANHEIT 2007

As advertized, Tim Bray gave a keynote presentation at CANHEIT 2007 earlier today (May 29, 2007). And even though I would not describe Bray as an overly dynamic speaker, he certainly did suceed in being entertaining, educating, engaging and thought provoking.

Hopefully, Bray’s presentation will be made available online.

Until it is, you may find the following data points of interest:

  • Bray spoke very highly of RAILS – RAILS in general, and Ruby on RAILS in particular. As a better way of doing things, he suggested that RAILS might even change the way you think about programming. To whet everyone’s appetite, Bray itemized two of RAILS’ principles:
    • Don’t repeat yourself
    • Emphasize convention over configuration

To substantiate his zeal for RAILS, he shared an example of a project that took four months to develop in J2EE; the same project was developed in five days with RAILS! The momentum behind RAILS is also quantified by book sales and attendance levels (in excess of 1,000) at a recent event.

  • Bray also spoke very highly of REST – Even as a Sun employee, Bray was compelled to state that REST may eclipse Java/J2EE in the not-too-distant future. Of course, like many, he suggested that the RESTful approach has already eclipsed Web services. He even shared an image of the WS-DeathStar (Source: Unknown).

  • Bray is contributing to the Atom Project – “Atom is a simple way to read and write information on the web, allowing you to easily keep track of more sites in less time, and to seamlessly share your words and ideas by publishing to the web.” Looks interesting!
  • Bray made use of Apple’s Keynote presentation software – After seeing how Bray and Al Gore made use of Keynote, I broker down and licensed a copy of the software. In both cases, I was struck by the elegant simplicity of their presentations. After all, the purpose of presentations is to communicate. More on Keynote some other time I expect …
  • Bray blogs at http://www.tbray.org/ongoing – Worth reading!

Annotation’s Two Solitudes

Most fundamentally, and despite the fact that the term is frequently used, annotation has not been universally defined. Although annotation can be fairly consistently regarded as editorial metadata, or even information about data, there exists considerable latitude regarding the origin/destination scope of annotation. In the language-centric OWL context, annotations originate internal to the ontology and can annotate internally and to some extent externally. Anecdotally, this remains a common usage mode for annotation as evidenced in the online and off-line literature plus most-mature scientific projects. In contrast in the referencing-based case of XPointer, annotations originate external to the formal ontology, and can annotate the ontology itself or make external references. (The figure below attempts to clarify this not entirely subtle distinction.)

The two solitudes with respect to definitions is carried forward in terms of differences in annotation terminology. As a very concrete example, both the OWL and XPointer communities separately define and make use of the same annotation properties or types. There is clearly an opportunity for the W3C to better harmonize the efforts between these distinct communities, their efforts and common interests.

Annotation Location versus Outcome

The iPhone: The Ginsu Knife of Phones!

Not since the ginsu knife, has there been such a versatile tool.

To better appreciate this versatility, have a look at Conan’s take:

CANHEIT 2007: My Presentation Now Available

I’ve made the presentation I made at CANHEIT 2007 available online.

This presentation corresponds to the abstract I wrote for the same event.

I hope to find a few femtoseconds to blog about the event soon!

Wanted: J2ME Version of Google Calendar

The fine folks at Google recently announced:

You can now access your Google Calendar account from your mobile phone! Just visit mobile.google.com/calendar/ with your phone’s web browser and once you’re logged in, you’ll see your list of upcoming events with date and time information in an easy-to-browse format.

This is great!

However, what’d I’d really appreciate for my BlackBerry is a J2ME version of Google Calendar.

Since Google already delivers a J2ME version of GMail for my BlackBerry, I hope that the J2ME version of Google Calendar isn’t too far away …

Tim Bray to Speak at CANHEIT 2007

Tim Bray will deliver a presentation entitled “Interconnectedness” at CANHEIT 2007 next week at the University of Waterloo.

Apparently, Mr. Bray delivered an excellent keynote at last year’s OUCC event.
