Effective MEF (Managed Extensibility Framework)

I’ve been working heavily with Managed Extensibility Framework (MEF) as part of Prism v4. Through this effort (and by regularly pestering Glenn Block with questions), I’ve compiled some guidelines that I find useful. I’ve based my guidelines on a style I first saw in ‘Effective C++’ by Scott Meyers. I like his use of the word “judiciously”. [...]

Performance Counters

In a variety of projects we’ll spin up a lab for performance testing, and people like Benny, Fred, or Beto will do that “art and science” thing, proceeding with both regimen and intuition towards possible bottlenecks and solutions. Whether it’s available memory, average physical disk read queue length, average number of requests per second, or [...]

Rewarding Behavior

This past weekend my wife and I attended The Incredible Feast, an outdoor event in the University District where 28 of Seattle’s best chef’s used ingredients from local farmers to create some serious culinary delights for guests. In our eco-friendly corner of the country, the Feast asked us to not print out the tickets, but [...]

Seasoning

Last summer at the Bellevue Farmers Market I had a chance to chat with Eric Bahn, owner of Monsoon restaurants. I had met the young chef of his Seattle restaurant a year earlier at a charity event, and I recalled at the time that he felt she had great talent and potential even though she [...]

I’ve spent three of the past four days traversing the terrain of emotionally significant life events: Friday my wife and I dropped our daughter off at an out of state college, Saturday we attended a wedding of a family friend (the bride was just a few years older than our daughter), and Monday we were [...]

x264 encoding with IIS Transform Manager

I recently got the time to play with the IIS Transform Manager and the X264 encoder.  I’ve created a Transform Manager task that allows for using X264 to encode videos by dropping files into a watch folder.  I based my work off of Ezequiel’s excellent blog post about integrating the RCE with Transform Manager. While I’ve [...]

Sharepoint 2010 – Change SAML Token Lifetime

  Yesterday I went trough and interesting analysis with Matias about how is the best way to tweak the SAML Token Lifetime for Sharepoint 2010 web applications using ADFS as a Claims Auth provider. We have basically three cookies to worry about in this scenario. The Authentication cookie, the Account partner cookie and the SharePoint cookie.  The [...]

Sharepoint 2010 and ADFS - Sign in as a different user

It is up to the application to do a proper federated sign-out and Sharepoint 2010 OOB is not doing this in the correct way. If you take a look at the HTTP conversation with fiddler Sharepoint will not call the wa=wsignout1.0 action on ADFS, it will simply clean the current authentication cookie. How to configure Sharepoint [...]

Browsers and Cookies

Near our Bellevue office are several delightful cafes, restaurants and markets that offer many temptations to those who work nearby. During lunch one day I stopped by a small store across the plaza to buy a drink, and as I waited to pay I was suddenly mesmerized by this spectacular work of art on the [...]
