I've been finding it difficult to work Clojure into the mix at my job
due to its Lispiness, therefore my experiences have been isolated to
free time hacking. However, I hope to make some headway on getting
buy-in on using clojure.jar -- specifically the immutable structs and
the Ref class. I was

I used Clojure recently for prototyping a piece of a face detection
system running on Java ME. I had learned a bit of Scheme and wondered
if there was already a Lisp implementation for the JVM. A little
search and then I found it.
When I started playing with it, we could already locate a face in

That is curious. Ordinarily one only needs one instance of any

Taken from http://en.wikibooks.org/wiki/Learning_Clojure:
Java includes wrapper reference types for its primitive number types,
e.g. java.lang.Integer "boxes" (wraps) the primitive int type. Because
every Clojure function is a JVM method expecting Object arguments,
Java primitives are usually box

What are the type hints on primitives.
For example,
long abc = 3
is the type hint
#^long
or
#^Long
I also saw use of the java assembly? syntax before:
#^[[L?
or neither.

Hi Justin,
The easiest solution is to download the sample code for the book from
[1] (this is referenced in the Preface under "Downloading Sample
Code"). The sample code includes everything you need: clojure, clojure-
contrib, and the book samples, plus launch scripts that get all the

code, so I don't know where to reduce my memory. But I thought these
stats were interesting on the number of Clojure objects created.
Right now, the apps is e
Hi Tim,
Thanks for the feedback and for taking the time to read the article. I
realized that pmap was probably a better solution as I was writing the
code, but pmap doesn't make for much of an agent demo, so I carried on
with my original plan. The point you make about bucketing is very
interesting
Never mind.. I talked to a local Ruby guru who explained Rack to me.
I went ahead and replaced my Jetty server script with a Ring server
script and everything worked. I'm surprised it only took about an hour
to do.
The Ring adapter and server will be added in the next release.

A not very elegant way would be to simply use (class (make-array Byte/

I've taken a look at Ring's Github pages, but I still don't fully
understand it. Is there a good tutorial on how to use it, or is it
best just to look at example code?

How do I dispatch on Java primitive array? I mean, my dispatch

No; you need to get it from the git-repository at

(and don't forget to include the built JAR in your classpath).

I'm currently using terracotta as both a message passing fabric in a cluster

I'm not measuring performance hit, mainly because the machines i have are
