Hi,
How can I find out all the namespaces in a library like

IIRC, dispatching to agents (via send or send-off) during a dosync
only happens if the transaction was successful (this was discussed in
several places, though http://clojure.org/refs does not mention this;
maybe this should be included there, if this is really something that
is guaranteed).

Yeah, this is not a platform-specific problem; it's simply not supported
in swank-clojure. I'd love to get a patch to fix this,

I used the CPU utilization monitor in Linux.
I adjusted the loop so it took about 5-7 seconds.

Hi Patrick,
Unfortunately, Incanter doesn't have any convolution functions, and
I'm not sure Parallel Colt does either. So I think you'll need to roll
your own.

The semicolon character opens a single-line comment in Clojure (as is
traditional in lisp languages). It's like // in Java.

Just to update, I've confirmed that this also happens on Ubuntu Linux.
I did a fresh install of ubuntu and followed the guide at:

Cute hack. Won't work if init is false or nil, though, unless the validator

Mark,
What tool did you use to see the CPU utilization, especially when the
test run time is so short?
Just curious.
