We hiked up the Keechelus Ridge today. This is a moderately steep climb from the Price Creek Sno-Park. In just about three miles, this trail climbs over 1600 ft.
In Magic Signatures for Salmon, John Panzer describes a way to pass signed XML data without involving XML canonicalization (c14n). Anyone who has dealt with WS-Security specs knows that canonicalization can be fragile (back in my days at BEA, getting signatures to work on the WebLogic stack turned out to be hard due to bugs in the c14n implementation) and slow. John Panzer’s approach is quite simple, but it requires introducing an XML based envelope format.
In the ideal world, what we see is the current. In the distributed software world, what we see may be stale. We can't tell. Would not it be nice to specify a cache invalidation API such that the source of the change can notify everyone that it changed? That is what an OpenSocial 1.0 draft [...]
The due date (February 8, 2010) for WS-REST 2010 First International Workshop on RESTful Design is fast approaching. There is still time to submit papers for this workshop. Topics include:
Applications of the REST architectural style to novel domains
Design Patterns and Anti-Patterns for RESTful services
RESTful service composition
Inverted REST (REST for push events)
Integration of Pub/Sub with REST
Performance [...]
Most illustrations of the hypertext constraint (aka Hypermedia As The Engine of Application State) focus on managing application flows using links. In this approach, the server describes the flow using links, and clients, by interpreting link relations follow the links. While such an approach is useful for illustrative purposes, baking all the flow assumptions into [...]
This is a short (under four miles) hike on a well groomed (but icy) trail to the upper fails in the Johnston Canyon on Dec 30, 2009. The falls are not completely frozen yet, but we were!
