I’ve been playing around with partially applied functions in Clojure, and have hit an interesting snag when dealing with Java interop. First, lets examine what partial does in Clojure, by cribbing off an example from Stuart Halloway’s Programming Clojure: user=> (defn add [one two] (+ one two)) #'user/add user=> (add 1 2) 3 user=>...

Posted in the “I hope no-one else has to go through this” category in the hope that Google surfaces this for some other poor soul. Picture a rather trivial split function: (defn split [str delimiter] ((seq (.split str delimiter)))) Which helpfully spits out: java.lang.ClassCastException: clojure.lang.ArraySeq cannot be cast to...

A friend of mine is suffering from a nasty, progressive condition called Motor Neurone Disease. There are many forms, all of which share the common trait of affecting the motor neurons which control walking, speaking, breathing and general movement. In the US it is often called ALS or Lou Gehrig’s disease. Prognosis varies, but the [...]

The talk I did at QCon SF 2009 is now available at infoq. Only an MP3 download is available, otherwise you’ll have to stream it from the site – but you’ll be missing a lot, as the slides are better than hearing me drone on.

At a recent ThoughtWorks techy meetup, we recorded a couple of videos for internal use. One of them involved someone speaking to slides. The problem was that we had no projector, and our flip camera wasn’t really up to doing a great job of filming the screen. So the problem I was faced with was [...]

I’ve been invited to speak on colleague Chris Read’s track at QCon London this March. The track itself is chock full of a number of experienced proffesionals (including two ex-colleagues) so I fully intend to raise my game accordingly. We’re lucky enough to have Michael T. Nygard speaking too, author of perhaps the best [...]

I’ve recently been working on a Clojure application that I hope to open source soon. It’s been my first experience of using Clojure, and is almost certainly one of the most thought provking things I’ve done in a long while. One of the things that is still causing me issues is how to go [...]
