In this interview, Yukihiro Matsumoto talks about programming languages design and decisions he had to take while designing Ruby. He also discusses other programming languages including Haskell, Scala, Python and Clojure. While talking about Ruby language and functional programming, Matz explores opportunities of integrating some of FP into Ruby and imagines a purer IO approach for it.
Philipp Haller and Martin Odersky introduce a type system that enables safe massage transfer in Scala actors. Formalized as an extension of the EPFL Scala compiler, “Object Capability Types” system, based on capability checking and external uniqueness, enforces race safety without sacrificing performance and removes significant limitations on message shape imposed by existing approaches.
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.
The beginning of the year is often conducive to formulating predictions about the trends that are likely to gain momentum in the coming year. Along with many others, Samuel Greengard and Dion Hinchcliffe came to suggest their list of technologies and approaches that will help architects providing value in this year 2009, at the crossroad of economic crisis and expansion of Web 2.0.
Have you ever wondered why people talk about having "the right language for the right job"? Or why people talk about using more languages within the same system? Sadek Drobi explains why you should consider mixing languages within your system, how to think and what to consider.
Sadek Drobi shows how he applied functional programming principles to a real-life project which needed to meet certain performance requirements. He shares the lessons learnt on using mutation, laziness, recursion, functions, monads, list comprehensions and parallelization in an attempt to achieve a functional domain model.
John Hughes has ported QuickCheck from Haskell to Erlang. In this interview, he contrasts the two languages, outlining features that he finds more attractive in each of them. He also explains how QuickCheck works and what makes it different from unit tests.
Francesco Cesarini and Simon Thompson talk on Erlang features and what makes it a powerful concurrent language in a discussion centered around their book entitled “Erlang Programming”. They talk about design patterns, functional programming, type annotations, hot software upgrades, influences on other languages, using the VM for other languages, and others.
Joe Armstrong and Simon Peyton Jones discuss Erlang, Haskell, the origins and development history of each, concurrency models, virtual machine implementations, comparisons to Scala, the mental model of a programming language versus the implementation, performance and optimization, and static versus dynamic typing - they both also make some surprising revelations.
