I won't say anything about my presentations (that's for others to say :) ). The point of this post is just to let you download them. So here they are:

• SOA Patterns (2.14mb) - Takes a look at different strategies (patterns) to solve common SOA pitfalls
  
• Getting SPAMMED for architecture (4.56mb) - Takes a look at the activities architects can/should do when they think about software architectures. The presentation also covers architecture in agile projects.
