Greetings,
I gave a short presentation on getting started with Clojure on the
AppEngine tonight at the clj-la meetup.
Slides can be found at
https://docs.google.com/present/view?id=ah82mvnssv5d_1784s26pwsh
Comments welcomed.
Enjoy,

Actually if you want to use java lib. Look at guava, formerly known as google
collection. It's one of my fav java lib.

Have you been able to "Build with Dependencies"? I haven't been able
to figure this out yet - though I suspect it's my inexperience with
Maven.

I've run Clojure for CLR successfully before on a different machine.
Just downloaded this distribution -

Running Clojure.Main.exe I get this:

They're stored in an AtomicReference (basically an atom).

Hi gents,
For those of you who have followed the development
of ClojureQL over the past 2.5 years you'll be excited
to know that ClojureQL is as of today being released
as 1.0.0 beta1.
That means that the significant primitives from Relational
Algebra are all in place and functional. The document
That's a great initiative!
And the logo is awesome! (Of course I'm biased, I grew up in Pac-Man
times.)

I did a bit more torture testing of clojure 1.2 and those JVM settings
this time for speed.
user=> (time (domany 10 (repeatedly gensym)))
"Elapsed time: 1362.33344 msecs"
{:foo
clojure.lang.Symbol}
user=> (time (pmap #(assoc % :bar 1) (take 10 (repeatedly #(domany

No problem! I'm glad theres other people interested in this :)
Theres still a lot I need to do with the site as theres very little
content there at the moment, but I'll get there eventually, especially
if other people are willing to contribute too.

Dan.

Thank you very much.
I will have a look at that tomorrow or try to extract a minimal code
for the problem.
Just to make sure: has there been any syntax change to definterface?
(To make it closer to defprotocol for example)
Best,
Nicolas.

I don't know if we can conclude that yet. It seems to be fastest on
one system with one combination of Java version

The CMS settings are best for low latency applications or applications that
want more predictable pause times. They can cause a drop in throughput for
scientific computing or for Extract-Transform-Load style programs. CMS is
not the default for historical reasons.

Hi,
I've been playing with the idea of creating a game development site
for Clojure for a while now and finally got around to setting up a
wiki for that purpose: http://clojure-games.org/
So far, there isn't much content there yet. I've linked any popular
game-related libraries, blog posts and co

Wow, that looks like a binary compatibility error. Make sure you're
starting with a clean directory
To both of you: this is just to say thank you for taking the time to
explain and advise in such detail. Really appreciated!

With those settings, it does not OOME even with 'eval'. It looks like
those settings allow infinite sequential function creation without
leaks.
I did not closely evaluate GC performance. However I must suspect
there to be some reasons why those settings aren't the default. I
wouldn't mind knowing
