• Can RDF really save us from data format proliferation? – The closest thing to a deployable web technology that might improve describing these kind of data mashups without parsing at any cost or patching is RDF. I’ve always found this particular argument by RDF proponents to be suspect.

  This course will provide a gentle introduction to programming using Python™ for highly motivated students with little or no prior experience in programming computers. The course will focus on planning and organizing programs, as well as the grammar of the Python programming language. Lectures will be interactive featuring in-class exercises with lots of support from the course staff.

• Windows Azure Blob Whitepaper

  This document describes Windows Azure Blob, and how to use it. Windows Azure Blob enables applications to store large objects, up to 50GB each in the cloud. It supports massively scalable blob system, where hot blobs will be served from many servers to scale out and meet the traffic needs of your application.

Arnon Rotem-Gal-Oz – Sagas and Workflows The Saga provides a context for set of messages to allow manging an effort for distributed concensus. It does not “orchestrate” messages (that’s what workflows are for) – you can read more on Saga’s in an excerpt from my SOA patterns book:  Saga pattern.

Ayende Rahien

• Rhino Service Bus: Saga and State - On the implementation of Sagas in Rhino Service Bus
  
• Rhino Service Bus: Concurrency in a distributed world – One of them [ways to solve the concurrency problem] is to ensure that this cannot happen by locking on a shared resource when executing the saga (commonly done by opening a transaction on the saga’s row). That can significantly limit the system scalability. Another option is to persist the saga’s state in a way that ensure that we have no conflicts. One way of doing that is to persist the actual state change itself, which allow us to replay the object to a consistent state. Concurrent updates don’t bother us because we aren’t actually modifying the data.

WSDAC#31 – Top developer mistakes

Martin Fowler – RulesEngine – The basic idea of production rules is very simple. In order to keep the implicit behavior under control you also need to limit the number of rules by keeping the rules within a narrow context. This would argue for a more domain specific approach to rules, where a team builds a limited rules engine that’s only designed to work within that narrow context.

• Ready for RDF?
• ESBs: Standards-Based vs. Standardized – ESB lock-in is much worse than a DB lock-in because (most) vendors want you to put their ESB in the very center of your company-wide architecture, whereas the DB is usually hidden behind the application’s outer boundary
• Snowflake APIs – The two developments (or rather ideas) Bill talks about are putting links into API data and standardisation of feed metadata; he predicts the debate will be around the use of custom data formats.
