Trusting IP Addresses

How do I find the address of a client connection to make a trust decision? Don't base security decisions on the perceived client address. Any address that we have comes from the underlying socket implementation and could be spoofed. The data that the

Annual Site Redesign

I don't actually promise to update the design every year but it makes it sound more exciting- as if there's some kind of recurring event that people might look forward to. This year's design focused on improving content readability. I removed some of

XQuery 1.1 Draft

Architect Insight Conference Talks

Slide decks are available from the Architect Insight Conference 2008 held in the UK at the end of April. These talks are fluffier than ones that I normally point to and since you only have the slides and not the audio, I recommend picking a few based

Naming Contracts for Versioning

Some tips for building support for versioning into the naming of data contracts. First, the primary route for versioning should be through the namespace part of the contract rather than the member name part of the contract. Versioning the contract through

Transaction Header Magic

Simplicity is elusive. A few weeks ago I learned that part of transaction flow, propagating information about the source machine between the client and server, is more complicated than I thought. It's not that the details were inherently complicated but
