What Value for Incremental SOA?
John Moe discusses a range of approaches to SOA, including incremental (Guerrilla) SOA. This has caused a stir in the SOA community with representatives from vendors and consultancies alike trading value-based blows (for instance which is the greatest cost, software or people?) to try to illustrate the benefits of these (their) solutions.

SOA Manifesto Released
After several days of intense effort, the SOA Manifesto has been released. As could be expected, the feedback so far is mixed, but is that because the Manifesto is flawed or because the message has not been understood (or communicated) correctly?

Development of a SOA Manifesto
In parallel with the 2nd SOA Symposium, Thomas Erl and representatives from companies such as IBM, Red Hat, Oracle and Cognizant are meeting to define a new SOA Manifesto. Steve Ross-Talbot, one of the working group members, writes on some key areas he would like the group to consider.

DeMarco Reflects on 40 Years of Software Engineering Evolution
40 years after the NATO Conference on Software Engineering, Tom DeMarco paused to reflect on the discipline's evolution, wondering whether the metrics orientation he championed has distracted from the real point of computing: "transformation, creating software that changes the world." Is his earlier advice valid, though? "No", he said, in Software Engineering: An Idea Whose Time Has Come and Gone?

Interview on Wolfram|Alpha, a Computational Knowledge Engine
Wolfram|Alpha was launched two months ago. It is time to review a few frequently asked questions: What is the relationship between Wolfram|Alpha and Google? How would Wolfram|Alpha position itself in the market? To what extent is Wolfram|Alpha a Semantic Web search engine? And how could Wolfram| Alpha make profit in the market? An interview with Xiang Wang, Wolfram Research, China.

Partition Your Backlog for Maximum Mileage
Backlogs have been under constant criticism for quite some time now. Mary Poppendieck suggested that the product backlog should be eliminated if it is not satisfying the desired purpose. Serge Beaumont suggested an interesting way of partitioning the backlog such that it maps to a flow and makes the backlog worthy for existence.

Should We Rely on Language Constraints or Responsibility?
Bruce Eckel, Michael Feathers, Niclas Nilsson, Keith Braithwaite, and others on the question: should languages be fully flexible, allowing the developers to tweak them as they like, and trusting they will be responsible in their work, or should there be clear constraints set in the language from its design phase to avoid mistakes that create bad code, hard to maintain or to read?

Cross-platform Development – Lessons Learned from Banshee/Mono
In a Scott Hanselman interview, Aaron Bockover of Novell talks about the challenges to create Banshee, a cross-platform application built in C# on Mono for Linux, Max OS X and Windows.

Article: Metamodel Oriented Programming
In this article, Jean-Jacques Dubray questions the belief that code and models are two separate worlds. He presents a unified view of Model Driven Engineering, Architecture and Programming models based on a novel approach to specify execution element semantics in DSLs.

Wolfram|Alpha, the Details Behind the Rhombic Hexecontahedron
Wolfram|Alpha uses symbolic computation in an attempt to make the world’s systematic knowledge computable. It does that by accepting a linguistic input not a custom set of formulas. The main components of the system are a data curation pipeline, an algorithmic computation system, a linguistic processing system, and an automated presentation system.

SOA Meets Formal Methods
In a recent blog post Steve Ross-Talbot, one of the main authors of the WS-CDL specification, discusses how he has been using a CDL-based methodology in insurance services and seen an 80% reducing in time to develop and deploy SOA successfully.

Father of Use Cases Says Agile Needs to Get Smarter
At the Software Education SDC conference in Melbourne, Australia, and Wellington, New Zealand, last week, Ivar Jacobson, author of the original work on Use Cases, the Unified Modeling Language and the Rational Unified Process, said that Agile development needs to “Get Smart”.

Presentation: A Kanban System for Software Engineering
David Anderson presents a brief history of the kanban system through case study reports from teams at Microsoft and Corbis. Kanban acts to limit work-in-progress and focus the team on achieving a continuous flow of value to the customer and innovates on accepted agile management practices by providing an iteration-less process with a regular release cadence.

Backlog Lacks the Backbone
Backlogs have been under criticism for some time now. Mary Poppendieck goes to the extent of suggesting that product backlog should be eliminated if it is not satisfying the desired purpose. On similar lines Jeff Patton suggested using story maps instead of flat backlogs which help focus on the system being developed.
