Just released Avout 0.5.2, which now includes automatic STM

Great catch, I had intended to fix the figure before release but forgot.
It's fixed now.
Today we are releasing Avout, which brings Clojure's in-memory model
of state to distributed application development by providing a
distributed implementation of Clojure's Multiversion Concurrency
Control (MVCC) STM along with distributable, durable, and extendable
versions of Clojure's Atom and Re

I think the problem is that additional classpaths are added,

evaluated if it's in ./ or ./src, which are added at launch in the

Unfortunately, group-by is a commonly used function name, used in both
Incanter and swank-clojure. I've renamed Incanter's group-by to group-

Ah, you're right, only the bin/swank script calls maven the clj and
clj.bat scripts are stand-alone, I thought I had changed them (but
it's better that they're stand-alone).
Was the following the actual error?

There are two solutions to your problem, 1) use the bin/clj script
which calls mvn clojure:repl from the modules/incanter-app directory,
or 2) just cd to the modules/incanter-app directory and then run mvn
clojure:repl your self.
That was described in the post you linked to, but it's easy to
miss.

Despite my preference for an east coast conference (and my limited
interest in JavaOne), I think it makes a lot of sense to have the
ClojureConj start on the Friday after JavaOne.

That's fantastic news! I wholeheartedly recommend Autodoc, it has been
great for the Incanter project.

I uploaded a version of Compojure to Clojars, that depends on the

I agree, use Clojure vectors whenever it's feasible. Even within
Incanter, which uses Parallel Colt extensively, I try never to convert
Clojure vectors into Colt vectors/matrices unless it's absolutely
necessary.

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.
You can find the Incanter API docs here: http://incanter.org/docs/api/
and the Parallel Colt API docs here: http://incanter.org/docs/pa

Hi Anand,
Try changing the INCANTER_HOME variable in the clj script to the
absolute path to the incanter directory, instead of a relative path,
like ./ or ../
Let me know if that doesn't work.
