Haskell and the Arts

Posted by Paul Hudak  on  Jul 06, 2009 1

Paul Hudak explores the question whether the elegance of functional programming is a good match for the aesthetics of art? Is it possible that artists could benefit from using functional languages in their work? In addition to the creative process, can functional languages assist artists in other ways? We will explore many of these issues in the context of the visual, musical, and performing arts.

Erlang Concurrency, What’s The Fuss?

From Concurrent to Parallel

Posted by Brian Goetz  on  Jun 19, 2009 3

Multiprocessor systems have gone from being rare and expensive to being ubiquitous. As the hardware reality changes, so do the programs we want to write and so must the platform and libraries we rely on. In Java SE 7, the java.util.concurent package will grow to address the need to exploit finer-grained concurrency, in the form of the fork-join framework.
