In July 2011 I received an email asking if I would write an article about Erlang for the IEEE Computers in Science and Engineering (CiSE) magazine. The email said they had first invited Joe Armstrong but Joe had recommended me instead — how could I refuse a request like that? :)
It took awhile, but my resulting article “Concurrency and Message Passing in Erlang” is now published in the Nov/Dec 2012 issue of CiSE. Here’s the abstract:
Developers use the open source Erlang programming language in domains such as telecommunications, database systems, and the Web due to its superior support for concurrency and reliability. Erlang applications comprise numerous processes—lightweight user-space threads—that communicate via message passing. This article focuses on Erlang’s concurrency support and details an example 1D Poisson solver program.
Due to IEEE copyright rules I’m allowed to post only the final draft (PDF) sent to the magazine’s layout folks, but that’s OK since its text and figures are identical to the final published version. I haven’t yet received my hard copy of the magazine, but it looks like an interesting issue; it’s a special one covering concurrency in modern programming languages, and it also contains articles about Haskell and Clojure. The guest editors’ introduction explains the issue in more detail.
