Very glad that test is now part of clojure core.
I've run into 2 strange behaviours when trying to write tests where
threads are involved. My case is a little complex so here is a minimal
version which shows what I mean:
test-test.clj:
(ns test-test
(:use clojure.test))
(deftest testathon

I second this suggestion to add the video to clojure.blip.tv. It felt

Java interop in practice. Congrats to Stuart. It was also very nice to

Thanks, I llke that much better!

I should have been more clear when I said to use (disj ...); I meant
sending that via an alter.

A few recommendations just at the "look and feel" level:

A set might be better to hold the player-refs, then you can just call
(disj player-refs player-ref) without doing any extra checking.
Also you can access ref values without needing to be in a dosync.
Things being immutable, the value you get from, say, @team-ref won't
change once you have it.

Thanks for the tip on looking at clojure.contrib. I keep forgetting to

I wrote some fairly simple code to demonstrate use of StructMaps and

I think one shouldn't generalize from one [unverified] example.

Hi Phil,
Part of me hopes there's a nicer way of doing this, but I was able to
get it working using:
(defn bi-get-pixels
[#^BufferedImage bi]
(let [raster (.getData bi)
pixels (.getPixels raster 0 0 (.getWidth bi) (.getHeight bi)
(cast (Class/forName "[I")
If you need a JSON parser, there's already a good one included with
clojure.contrib. The one with the FnParse library is just a sample to
show how it works. But please feel free to use it however it can be
useful to you. :)

Parth,
I've created a little wrapper as promised at: http://gist.github.com/141001.
It gives you my-pprint:

While doing this, I realized to my horror that ~r doesn't do 0

Each iteration contains 266 instructions. So, it is more like 10.5 clock
cycle per instructions.
Probably the cost of the method call, that I had to introduce in order to
have the JIT compile, or the fact that the status register is
not directly in a local variable but with an indirection, because
I had this:

(concat [sum] (subexpressions-of-product (cons sum prod)
in a source file with other definitions. Load-file worked. I then

Hi,
The following code works as expected:

Interesting talk Stuart, thanks for the link.

You're right, the scenario that I described doesn't need it. In my
actual code I need it because the function actually reads
#(conj (or % #{}) constraint#)
If I don't do that, I get a list instead of a set.
