“Icky” Decisions

@KeithDahlby posted a good question for thought the other day on “the” Twitter:
When implementing the Observer pattern, how do you handle exceptions from observers?
This seemingly harmless question should spark at least a good 15 minute debate. An obvious question (and the one I asked):
Do you care if an observer throws an exception?
If you consider [...]

If you have spent anytime in WCF land the first thing you learn about is the joys of configuration. For the coming release of .NET 4 and WCF 4 the team heard that feedback and has made configuration much easier for the development experience.

Reclaiming Your Identity with Windows Identity Foundation
Windows Identity Foundation is a new framework from Microsoft that helps to solve the identity crisis so many users face with multiple accounts for on-line services, applications, etc. WIF (dub-eye-eff, not “wiff”), supports the notion of claims-based authentication where a user will authenticate with an external provider and return to your application with a set [...]

Before I get started, I’ll just say that if you are here to read about things I learned or saw at the summit you will be disappointed. Most all of what I saw and learned was under NDA, so I won’t be talking about any content. What I will talk about is the experience and [...]
All Quiet on the Midwestern Front

I am having bloggers guilt. The last few weeks have been seen a low posting volume. I have not taken any vows of silence; my schedule has got the best of me. I’m off to the MVP summit, my first, and I’m extremely excited to get a chance to travel to Seattle and meet fellow [...]

After battling with error 0×80004004 the WCF client I was testing started received a new error.

Calling SharePoint Services Over SSL with WCF (WSS 3.0)

Posted in SharePoint | No comments
While troubleshooting another SharePoint WSS issue (related to DCOM permissions) I had to test calling the List Service against an Instance of SharePoint that was running over SSL. I was using WCF as the client and the biggest pain was the configuration (which is usually the case with WCF). Based on several other posts, here [...]

Today I spent some time working through a few issues with SharePoint and DCOM permissions. Hopefully this helps another developer on a quest to solve this issue.
If you’ve found 0×80004004 then you are already pretty far along to the solution. While testing calls to the List service in SharePoint using WCF for the client I [...]
How to Make Coffee Undetected

I love coffee. My wife loves coffee. Except when now that she’s pregnant (again). A few weeks ago I received a request to cease coffee making at home because the smell was a little much for my wife to take. Apparently baby on the way (#3) does not appreciate coffee.
This situation wasn’t going to work [...]
Back to ‘Getting Things Done’

Years ago, when I was working in libraries, I had the chance to read David Allen’s Getting Things Done. The impact of that book took a while to really sink in and combining that with Inbox Zero a few years later I was on my way to a GTD system. Unfortunately after a good year [...]
