I've heard a lot that Google App Engine's use of many JVMs makes
Clojure refs, etc. less useful than they are on one JVM. I'm curious—
what are the consequences of using a ref normally in Google App
Engine? How would it be broken? Would each JVM, invisibly, each store
a different value for the
Hello guys,I've read the Stuart Halloway's book, worked through it, and I've

I'm using Clojure 1.0.1-alpha-SNAPSHOT with emacs + slime + swank.
Until now, everything went smoothly, however as my code went bigger it

Oh, and by the way: the expression (+ 1 2 3)
is indeed a constant. Be very wary of
tests that verify the execution speed of
constants since it is definitely the goal of
the JVM developers to make the JVM compile
these into a single constant mov in the machine code!
Of course such code is so fast
Hello all,
I'm trying to integrate an REPL in a existing java project, but i dont
know how it works or where to start.
At first it should only have the functionality from an ordinary clj
repl. Later we want to extend it with some functions and macros, to
control our software via console.
Help
Works for me. Thanks!

Hi.
Thanks all, for your comments.
You need to use a bigger number than 1000 for these results to be
meaningful.
Out of curiousity, why is this?
Does the JIT do something different after 1000 iterations?
Or is the concern

Roger, your code is not event based.
