I’ll be presenting in the Killer Example Workship. This group is focused on coming up with killer examples and processes for teaching university students design patterns. We’re scheduled for October 21 at 12:30 in Montreal. Also, I’ll be going to the educational symposium on OOP in the classroom.

My favorite quote came from someone on my panel last year who was presenting a new DP. I asked him if I could use Flash Media Server as a remote proxy in his model, and he said I could use smoke signals if I wanted—the point being that the structure of the design and not the tools (language) used to achieve the structure is the focal point. So like FMS, I’m certain that CF will be welcomed as well to OOPSLA. The people there are so freakin’ bright you’ll be amazed!

Anyway, I’m planning on using the Flyweight Saga (which better be a completed story by then!) to walk students through a flawed idea to a deeper understanding of what’s going on in the structure of the design pattern. What little I’ve done so far with DPs in the classroom ends up with students copying and pasting or just making minor changes to existing code. I’m putting this up as a way to trip over a few mis-assumptions and lead to a deeper and clearer understanding. (I’m always going through that process myself!).

Hope to see everyone in Montreal,
Bill

If you think flying the AS flag is strange, I’ll be flying the ColdFusion flag :-> I’m doing a practitioners report on a high volume software product line I developed in CF and will be presenting at the co-located Domain Specific Modeling forum on automating transformations of statements in DSLs based upon a catalog of types of grammatical transforms to the underlying DSLs.

Please feel free to drop me a line if you’re attending - I’ve never been before, so it would be great to know someone - if only in passing!

I think that this part does a partial clarification on “extrinsic” states, but I still feel, I’ve got a ways to go. In looking at the GoF example it seems that all of the extrinsic states are generated by the other concrete classes. My big problem is that I can only do this in between other projects that pay the bills! If I were asked what my hobbies are, “Design Patterns” would be my reply.(That might generate a “get a life…” reply, but that’s what it is right now!)

I was invited to present again at OOPSLA in Montreal, and I’m going to use the Flyweight saga as a way to navigate through understanding this thing better. OOPSLA is where DPs originated, and this time I’m going to do my best to meet the GoF (minus 1 who died). It’s sort of like planting the ActionScript flag on the moon — all of these people are Java, C and increasingly C# folks. Last year in the session, they fried the Singleton and presented the the Symetric Proxy DP (that’s in the book) and so this year I’m going to see who else may possibly attend because it’s in such a cool place–Montreal.
