PC vs Mac

It seems like the blogsphere is getting very busy of late with PC vs Mac (or Mac vs PC, whatever your pleasure) arguments, adverts and mud-slinging. It reminds me of the following video which I originally got via email about three or four years ago.

Classic.

Frozen Five - www.frozenfive.org

As my wife and I were traveling through New Zealand last year, we were fortunate enough to met a great Swedish couple (Anna-Lisa and Mats) who we were able to travel with for a few days. On the 29th of March, Mats is going to start a Svalbard Skiing Expedition with a group of other geoscience students from around the world.

As I am in drought ridden Australia with dead grass all around my house, city and state, I find this absolutely fascinating. Anyway, check out their site and blog.

Wizard framework RC released

I have been working on a winforms wizard framework for a while when I get the chance. My aim with this project is to be able to create a reusable framework for wizard style dialogs and pages for the 2.0 .Net framework.

The first RC version of my WizardUI has been released on CodePlex. I would appreciate any comments. You can find the release here.

Be careful of code clean-up's when you have WF projects

I am really enjoying using WCF and WF in my development. While playing with the new toys can be frustrating at times, it is a whole lot of fun. There are a few gotchas though. The one I want to highlight here is the “Find All References” support in the IDE. Here is a scenario that can bite you.

Let’s say that I am using PolicyActivities to do pre and post condition validation. I may also be using them to change data in the workflow based on rules. For example, I might need to do some business to data object mapping. To neatly achieve this conversion while avoiding a CodeActivity, I can have a rule in the PolicyActivity that calls a static method on a converter class. Now that my solution is created, I want to clean up the code to make sure I don’t have redundant methods.

In order to check if a method is being used, I would normally have used the find all references feature to see if the method is being used anywhere, but here’s the kicker. This feature (from what I can guess) only looks at code that will be compiled down to IL. This will not work when the method exists in a rules file because the rules file is simply compiled as an embedded resource.

When you have WF projects included in your solution, run a text search for the method, searching all files in the solution (not just *.cs files). Oh, and always re-run your tests after you can any code.

Last hurrah for the red dobok

Given my impending fatherhood, there have to be changes and sacrifices. I have been instructing beginners and intermediates at Taekwondo for about a year and a half. Tonight was the last night for me as an instructor so I have to give up the cool “go faster” intermediate instructor’s red dobok. Pity, I liked that one.
