Playing with some problems of 4clojure, I wanted to make a map which, for
each empty collection, returns a keyword. But it seems that it is
impossible to have both an empty list and an empty vector in the same map.
user= {() :list}
{() :list}
user= {() :list [] :vector}
IllegalArgumentException
Another interesting fact is that:
Clojure 1.2.1
user= {'(1) :list [1] :vector}
java.lang.IllegalArgumentException: Duplicate key: (1) (NO_SOURCE_FILE:0)
Clojure 1.3.0
user= {'(1) :list [1] :vector}
{(1) :vector}
Clojure 1.4.0-beta1
user= {'(1) :list [1] :vector}
{(1) :vector}
...but I don't
More examples in clojure 1.3.0:
user= {[1 2 3] :vector '(1 2 3) :list}
{[1 2 3] :list}
but
user= #{[1 2 3] (1 2 3)}
IllegalArgumentException Duplicate key: (1 2 3)

Maybe the reason is the STM.
If I rmember it correctly, then agents and refs are controlled by
Clojures STM mechanic. Eventuelly the us of map increase the work for
the STM and so it needs more time to schedule all the agent calls and
this result in a higher memory usage.
When you use pmap
Hmmminteresting thoughts...
I was under the impression that that agents are asynchronous and thus
do not depend on the STM , which is only for co-ordinated change! There
is a dedicated Thread pool where agents are assigned separate threads
for their work.You seem to suggest otherwise...I
Might be.
I have spent the last week to write some profiling code for the
algorithm, which also calculates the memory usage.
I wanted to try it out with the original code with different number of
dimiciles and with the pmap code.
But with the STM it is only a guess. I must reread the chapter
A short side note.
I looked into The Joy of Clojure and there is a nice diagram on page
251 about the difference if you use send and send-off to send actions to
an agent.
The intersting on send is, that the agent queues the send actions if you
use send. If you use send-off the agent does not

I am wondering if anybody in (or near) Rochester, NY would be interested in

me hacking on Clojure in the area!

Hi all,
If anyone was unaware, Dave Ray, author of the Seesaw Clojure library will
be speaking at the inaugural Great Lakes Functional Programming Conference
in Ann Arbor, MI on May 5. We're very pleased that Dave will be discussing
Clojure development with us.
More information here:
I needed something quick like Korma for my .NET work, so I ported it to
ClojureCLR. The code is here: https://github.com/aaronc/Korma.net. So far
only MySql is supported.
Right now, there is nothing like leiningen for .NET so no build and
distribution yet. Also, most of the code for the JVM
Hi,
sorry to be late to the party...

one shared data-structure and how the introduction of concurrent
programming can change the algorithms: in this case
Wow that is indeed very clear and informative...Thanks a lot!
I could not agree more! I was struggling to understand the 'meaning' of
the algorithm and what it was trying to demonstrate...as Stefan said,

There's a RocLisp group that meets once in a while (next meeting TBD).
We've been focussing on Clojure so far.

I myself am pretty nuts about Clojure. Looking forward to meeting and

Thanks for the answer.
I wondered too why the GA took so long to solve this small problem.
I tried send for the grimreaper, but this does not solve the population
increase problem. On a test run the population even increses much
faster, wehen I used only send.
But I must say I liked the idea
