The November/December 2012 issue of IEEE Internet Computing magazine contains my final “Functional Web” column covering the Nitrogen web framework. As with all my previous columns, this column is available here in PDF form.
My first column for IC appeared in March 2002, nearly 11 years ago. Back then my column, called “Toward Integration,” focused around enterprise middleware. My old friend Doug Lea, who was on the IC editorial board at the time, suggested that I write it, and who in their right mind would turn down Doug Lea? In March 2009 I stopped that column and began writing the “Functional Web” column, focusing on the use of functional programming languages and techniques for web development. Prior to writing for IC, I was a columnist for the C++ Report magazine, starting in January 1995, and then later continuing that column over in the C/C++ Users Journal. That column focused on distributed object computing, and I stopped writing it in 2005.
That’s a total of 18 years as a columnist, which is a lengthy duration for a side gig done on my own time (and for IC, done on a purely volunteer basis). My common goal for all the columns was to write for practitioners like me — to try to cover topics, approaches, and ideas that other software developers could immediately apply in their own work. I also saw column writing as a way to try to pay back all the authors from whom I had learned so much over the years.
But 18 years is enough, for now anyway. While I might return to publishing in the future, for now I just want to focus on technology and software development.
Thanks to all my readers for your feedback and encouragement over the years. You definitely made it all worthwhile.

My latest Internet Computing column, Server-Sent Events with Yaws (PDF), is now available. It discusses the fact that developers are increasingly building Web applications that rely on notifications from the server, such as updates from social networks, alerts from application monitors, or information from sensor networks. But given that HTTP is a request-response protocol, such notifications can be challenging, giving rise to techniques such as long polling and to entirely new protocols such as WebSocket. These challenges can be especially significant for mobile applications due to intermittent client connectivity and device battery-life issues. This column explores how the Yaws Web server, written in the Erlang programming language, supports the W3C Server-Sent Events notification approach.

I’m a little late in posting this, but in the July/August 2012 issue of Internet Computing, guest columnist Sadek Drobi covers the Play2 framework. Sadek talks about how today’s Web evolutions and the emergence of software as a service and Web services have led to new challenges in programming: distribution, scalability, management of various data formats, stream management, and so on. He explains that Play2 can significantly aid developers in capitalizing on the opportunities the Web offers while minimizing potential risks by leveraging the strengths of functional programming. He outlines functional programming’s power in this context at several levels: data and data format manipulation using higher-order functions; reactive composition with nonblocking I/O for scalability; and reactive stream processing and manipulation using Iteratees with WebSockets and Server-Sent Events. Here’s the PDF of the column.
The same magazine issue is also the “Programmatic Interfaces for Web Applications” special issue that Tomas Vitvar, Cesare Pautausso, and I co-guest-edited. Our guest editors’ introduction explains the purpose of the special issue and introduces the five articles comprising it:

For the “Functional Web” column in the Jan/Feb 2012 issue of Internet Computing, I wrote about Wriaki, an Erlang sample application my Basho colleague Bryan Fink wrote that implements a wiki on top of Webmachine and Riak. Wriaki is a nice, clean, and easy to understand example of how to write Webmachine applications. Here’s the PDF.
