Functional programming experts Simon Thompson and John Hughes discuss functional programming in today’s computing environments, particularly through the use of the Erlang and Haskell languages. In addition to debating the intricacies of both languages and their similarities and differences, Thompson and Hughes also discuss the growing popularity and maturity if functional programming.
Ralph Johnson and Joe Armstrong discuss their ideas about parallel programming - whether shared memory is harmful, the place of message passing, fault tolerance, the importance of protocols and more.
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.
Dan Ingalls explains the ideas that went into Smalltalk, how it was developed at Xerox PARC, the ideas that went into Squeak, and his latest project the browser-based Lively Kernel.
Joe Walker explains the browser-based source editor Bespin: the architecture and implementation, the collaboration features, new ideas for command lines, Canvas vs DOM, speed, extensibility, and much more.
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.
John Hughes is the author of “Why functional programming matters” paper and in this interview he outlines the merits of functional programming and the reason for his involvement with it. He also goes over several core principles of functional programming like monads, handling of side-effects, etc.
Jim Coplien, co-creator of Data, Context and Interaction (DCI) architecture, covers a variety of topics including DCI, the importance of language support for DCI and the state of Agile development. Coplien has championed the DCI architecture with Trygve ReensKaug, the inventor of the Model-View-Controller (MVC) architecture, which separates data and its processing from presentation.
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.
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.
