Java-Forum Stuttgart (06 Jul 2009)

After a presentation on Scala, I passed by a couple of flipcharts which were set aside for birds-of-a-feather (BoF) sessions. On a whim, I grabbed a free flipchart and scribbled one word: Clojure. In the official program, there was no presentation covering Clojure, but I thought it'd be nice to meet a few people who, like me, are interested in learning this new language and its concepts!

Since I had suggested the topic, I became the designated moderator for this session. It turned out that most attendees didn't really know all that much about Clojure or Lisp - and so I gravitated, a bit unwillingly at first, into presentation mode. Boy, was I glad that right before the session, I had refreshed the little Clojure-fu I have by reading an article or two.

In fact, some of the folks who showed up had assumed the session was on closures (the programming concept) rather than Clojure, the language But the remaining few of us still had a spirited discussion, covering topics such as dynamic versus static typing, various Clojure language elements, Clojure's Lisp heritage, programmimg for concurrency, web frameworks, Ruby on Rails, and OO databases.

To those who stopped by, thanks a lot for this discussion and for your interest. And to the developer from Bremen whose name I forgot (sorry): As we suspected, there is indeed an alternative syntax for creating Java objects in Clojure.

  (.show (new javax.swing.JFrame)) ;; probably more readable for Java programmers

  (.show (javax.swing.JFrame.)) ;; Clojure shorthand
