Hello.
If def- remains for historical reason, def- may be marked as
duplicated and will be moved, for example, in 1.4, 2.0 or so?
Thank you.

Edmund Jackson has put up a blog post that describes how integrate
LinkedBlockingQueue's with Conduit. It's a pretty good example of what
you can do with Conduit without too much trouble.

Hi Olek,
Could you explain how this differs from Hadoop in concept and in
execution? Thanks.

You guys are great! As my dad used to say when he had been greatly
helped: Each of you is a scholar and a gentleman.
I admire your expertise. You each had knowledgeable and quite helpful
suggestions. I ended up using Alex's ideas for getting the Leiningen
installation process to avoid Macport
Hi!
It is nice to announce that Sisyphus - the google's mapreduce
implemented in Clojure - has been released.

with english version.

bumped it to version 1. That means I feel safe offering it to you for
production use.

In my original message describing pmap's behavior, there was a little

Ok, I think I've got it - so basically all private variants should go
in contrib now and moving defn- now would break a lot of people's code
"just" for a little more coherency.
But in this case, I'd like def- to be included in clojure.contrib.def.
I dislike defvar as it's just name and docstring p

I have run across something else I don't understand about pmap. Why does the
following:
(pmap (fn [_] (clojure.java.shell/sh "sleep" "10")) (range 32))
result in all 32 "sleep" processes being run at once? I thought pmap used n+2

Hi,
constructors (like methods) are not first class. You have to wrap it
in a factory function.
(defn make-foo
[a b c d]
(Foo. a b c d))
(apply make-foo [1 2 3 4])

Quick question...I am trying to populate a record with values provided
in a list. I'm definitely doing it the wrong way...but maybe there's
no good way to do it.
Here's what I do (clojure 1.2.0 by the way):
(defrecord Foo [x y z])
(Foo. 1 2 3)
#:user.Foo{:x 1, :y 2, :z 3}
but then:

Mark, John, Gaz:
Your responses are all suggestive but I don't know where to go from here
so I am going to make one more cry for help -- and to this group rather
than the leiningen-specific one suggested by Mark because my basic
problem is really how-to-get-clojure/emacs-running-under-MacOsX.
Hello,
Seems like this might be a good time to say thanks to Laurent for all
the work he's done on CCW. FWIW, I've been using it for a while, and
never had any issues installing it (at least not from a clean
Eclipse), nor any of the other described issues.
So thanks Laurent, and keep up the good
