Presentation: Meeting the Challenge of Simplicity
This session addresses the abstract notion of simplicity, looks at why it is critical in modern UI design and answers questions: Why does simplicity matter? Is there a meaningful definition of simplicity? Why do design processes and good intentions undermine simplicity? What processes and techniques can software developers use to achieve simplicity?

Presentation: Practice-based Design: Some Object Lessons
In this OOPSLA 2008 session, Lucy Suchman teaches 8 lessons about objects: Learning to see, Classification, Object Agencies, Configurations, Boundaries and Interfaces, Contextualizations, Recontextualizations, and Transformations, showing how they can influence design.

Data, Context and Interaction : A New Architectural Approach by James O. Coplien and Trygve Reenskau
James O. Coplien and Trygve Reenskaug have recently introduced a new architectural approach to OOP based on Data, Context and Interaction pattern. It should allow capturing user mental model in terms of behavioral requirements, something that classic OOP fails to do. The article, that triggered many reactions and critics, provides insights into DCI using concrete examples to show its advantages.

Article: Using SketchFlow to Create Better Prototypes
Simon Guest of Microsoft introduces SketchFlow by discussing why prototyping is an important developer skill and how a tool can enhance developer-customer interaction. The functionality and features of SketchFlow are presented in the context of an ongoing sample application (an on-line store).

Advantages Of (Also) Using HATEOAS In RESTFul APIs
Craig McClanahan, from Sun Microsystems, provides answers as to why existing "REST" APIs don't really take advantage of using Hypermedia as the Engine of Application State (HATEOAS) in RESTful services. He cites examples from his recent work in designing the Sun Cloud API to illustrate the benefits.

Transaction Strategies Based on Java Transaction Models
It is a common mistake to confuse transaction models with transaction strategies. Mark Richards discusses the three transaction models supported by the Java Platform (Local Transaction, Programmatic Transaction, and Declarative Transaction) and four transaction strategies (Client Orchestration, API Layer, High Concurrency, and High Speed Processing) that can be based on those models.
