Ralph Johnson and Joe Armstrong discuss the state of OOP, what Smalltalk got right/wrong and the image concept. Also: Joe decides he likes OOP as long as its done the Erlang way: focused on messaging.
Udi Dahan talks about Command Query Responsibility Segregation (CQRS) and its relationship to Domain Driven Design (DDD). Dahan also discusses his project, the NServiceBus. NServiceBus is an open-source service bus for Microsoft's .NET environment. In many ways, NServiceBus works like Microsoft's Windows Communication Foundation (WCF) and can be used instead of WCF in some cases.
In this interview made by Sadek Drobi, Don Syme speaks about F# 2.0, its application fields, its integration in Visual Studio 2010 and F# open source Power Pack library. Don also discusses the genesis of F#, the ties with OCaml as well as its specificity. He explains how did OOP and FP mix into one language and mentions some of the language's design decisions and compromises he had to take.
Philippe recently spoke at the SDC conference about the importance of architecture, the relationship between architecture and Agile methods and the impact of technical debt. He discusses a number of false dichotomies that have emerged between agility and discipline and agility and architecture. He emphasizes the importance of context in selecting a software development approach.
This interview begins with a discussion of functional programming, the use of Scala by programmers trained in Java and the differences between purely functional languages like Haskell and hybrids like Scala. Later in the interview other programming languages are discussed along with the notion of programming paradigms and the need for combining both paradigms and languages to best solve problems.
SpringSource CTO Adrian Colyer talks to InfoQ about AspectJ. The interview explores how products such as Spring Roo are using AspectJ, and how ideas from AspectJ helped SpringSource improve the Groovy compiler inside Eclipse.

He also speaks about the DDD community as a whole.
In this interview, Greg Young talks about managing state transitions in a Domain-Driven Design project using two separate models, one for reading data from datastore and the other for write-only command operations. He also discussed Command Query Separation to keep the design cleaner and easier to test and maintain and the best practices that developers can use when working on DDD projects.
In this interview made during Agile 2008, Alan Cooper, the father of Visual Basic and supporter of interaction design, talks about his contact with the Agile movement and the similarities discovered between Agile programmers and interaction designers.
Eric Evans, the author of Domain Driven Design, interviews Greg Young about the architecture implemented for a system processing tens of thousands of transactions per second. It's not just the sheer number of transactions that is challenging, but the time constraints imposed are those specific to real-time systems. Greg reveals some of the architecture elements of the system's design.
