Grady Booch has a good post about SOA here. He called it Snake Oil-oriented Architecture, but I thought I could make it just a bit more tabloid. 😉

Ted Neward has an entry on how some people in the .NET community is a bit ignorant to the mistakes made by Java folks in the past here. Sadly the same mistake is still beeing made in Javaland today, but it’s probably getting better. 4 layers if indirection doesn’t help much if 100% of the data is beeing passed through all the layers. It just gives you heaps of code to maintain when something changes.
Alright, I’m way too busy these days to read through all of this, so this is more of a toread. I found an article on schema evolution over at Martin Fowlers bliki.
