An Introduction to BPEL. I just came across this elegant introduction to BPEL and the concepts of orchestration. I say elegant because it's short and sweet. The first slide tells most of the story: a mix of synchronous and asynchonous services, exception handling, and parallel async processes. If you understand these three issues, you're most of the way there. [Source; Collaxa]

ASN.1 Encoding for Fast Web Services. A group at Sun had published this article proposing a scheme for subtantially improving the efficiency of XML-based web services using Abstract Syntax Notation, used extensively in the telecommunications industry. The results are encouraging (4x to 10x), and they're hoping to get it approved by a standards body. [Source: Don Park who isn't thrilled with the idea. "This is one case where common sense differs from reality," he writes.]
Update: Rich Miller knows ASN.1 from 1982, and points out that it was used in X.400. He doesn't buy Don's fears of misuse.
