Sometimes it is useful to write a constructor function to initialize the

I have released a library for fusing a stream, decoder, and resource

resources. You can then apply a transducer to this object. This means you

A MethodHandle can be used for anything that the JVM can do from a static

Nice writeup John! Thanks very much.
Not sure if I made it into the first 10k developers, but I can't wait to
play with this.

Isn't it somewhat standard procedure in the Java world (or at least the
Maven world...sorry to bring that up again :)) to distribute with a
clojure-contrib.jar and clojure-contrib-sources.jar, one being only the
compiled classes and the other only being the source files?

Alter expects a function that take the current value of the ref it will
alter as the first arg. I think what you want to do is ref-set.
user=> (doc alter)
-
clojure.core/alter
([ref fun & args])
Must be called in a transaction. Sets the in-transaction-value of
ref to:

I'll just throw this out there. It may not be exactly what you're looking
for, but you could use a Terracotta cluster. Terracotta will persist the
cluster to disk. If you have an existing database that you are working with,
then this may not help, but if you are starting from scratch you may not

The operations will happen synchronously. Clojure will not add threading to
your code without you asking it to, but when you want to add threading there
are lots of great tools built-in to make it Easy On You (TM).

Yeah that works the same as defining a function, just more explicit. I was
looking for a way to define a constant and just use it as "my-const" without
having to use the parens to call a function or a macro. I guess that would
be something like a symbol macro in CL?

I think you are right, Brad.
However, I wonder though if there is a better way to define a constant.
Neither the macro nor function seems clean. I like David's
wrapping-the-whole-thing-in-a-let, but what if you wanted to access the
value of "width" in a different file? Would one have to resort to
This works great for Java libraries, but only libraries that are in a maven
repo. How hard is it to get code into a repo? What about java libraries not
in a maven repo, or clojure code like clojure-json on GitHub?

I got it down to about 3 seconds. I did what William said, but the biggest
improvement was from changing the way *width*, *height*, and *max-steps*
were defined. I noticed that in the Java version they are constants, but in
the Clojure version they are Vars which means that inside your tight inner

Hi Nathan,
There is actually a simple answer to your question. map can take a
fuction of multiple parameters along with multiple collections. i.e.
(defn f [x y] (+ x y))
(map f [1 2] [3 4])
=> (4 6)
(Warning I did this computation in the Clojure instance in my head, so
some details may be sligh
I have gotten to the point in my Clojure + Terracotta experiment, where I
believe all of the features of Clojure are functional (Refs, Atoms,
transactions, etc.). I do not have a way to extensively test the Clojure
functionality, but I have run the clojure.contrib.test-clojure test suites
