I have done the benchmarks and optimized the implementation. On my PC with
the new changes TransactionalMap is up to 5 times slower than
ConcurrentHashMap. You can find the benchmarks here:

Hi All,
Almost 4 years ago I developed STM with semantic concurrency control for my
project at CERN. Main feature of this STM is the TransactionalMap that lets
you merge concurrent changes. Library is heavily tested and is very stable.
It has been used in production for the past 2 years.

Hi Aaron,
Thank you for such an interesting post.
You wrote that you could not setup Emacs on Windows. I decided to show you
an easy way to do it.
1. Download vanilla Emacs from here:
http://ftp.gnu.org/pub/gnu/emacs/windows/
Latest version at the moment is here:
http://ftp.gnu.org/pub/gnu/emac
I'm pretty sure this is because of log4j.xml [1] in src directory of Korma.
I think it's take from here [2]. If you take a look at it, it sets root
debug level to "debug".
Try creating your own configuration and pointing to it with command line
argument:
-Dlog4j.configuration=your_log4j.xml

Hello Luc,
In all fairness I don't see how converting ints to Integers returned by
class methods would break the abstraction. If you start talking about
portability of Clojure code, then Long is as portable as Integer is. (In
general they are not.)
Could you explain your position on the fact that
I reread your original post, sorry I saw that you managed to declare type
constrained methods. Then, what was your question about?
Type hinting for arguments works as well:
(definterface Name
(^"[S" method [^"[S" short-arg]))
(def p (proxy [Name] []
(method [^"[S" short-arg] short-arg)))
Hello Herwig,
I checked the patch you linked to in your original post, and it doesn't seem
that type hinting for native arrays of Objects is supported, that is the [L
type. Native arrays of native types work quite well.
(definterface Name (^"[S" method [])) ;;returns array of shorts
(def p (proxy
Sorry I meant "Fair enough ..."
Cheers,
Ivan.

Fail enough. I guess, to allow nested spawning and avoid deadlocks, tasks
should finish without waiting for the result but spawn a new task similar to
itself that would check for the completion of the child tasks, repeating the
cycle if necessary.
Imagine that task t1 is monitored through a future
I wonder, would it be possible to throw a custom exception (something like
DoNotUse_InternalRuntimeException) in Reflector.java, and update try/catch
code to always unwrap it?
Cheers,
Ivan.

I feel myself silly, but could you explain how does this work?
(def +M (first [+' 1]))
Is it some kind of reader level trick?
Cheers,

Hi Ken,
Having a mutable stm-map would be awesome. I actually had to implement one
for my project at work. Sorry can't publish it due to licensing issues, but
anyway my implementation is dead simple and won't perform well on big data
sets. I was trying to understand how to implement detection of n
Hi Thomas,
You need to execute this line:
(dosync (ref-set location (read-json (slurp url
every time you want to re-query the string.
To do this periodically you could do something like this [1]:
(import '(java.util TimerTask Timer))
(let [task (proxy [TimerTask] []
(run [] (dosync (ref

Hello Konrad,
Git workflow is a little bit different. You don't really need commit rights
to contribute. I found a rather nice explanation of Git workflow here:

Hope it helps.
Cheers,

Hello André,
Just wanted to mention that Java 7 is feature complete. You can see the list
of approved features here:
http://openjdk.java.net/projects/jdk7/features/
It seems that JSR203 was selected for the release, although I remember
reading that Clojure won't support Java 7 for awhile.
Cheers
David,
Sorry, I misunderstood your question at first. There was actually a
discussion on it a couple of days ago:

Cheers,
Ivan.

Hello Saul,
Thank you for the suggestion, I was looking for something that would work on

I see that these snippets can be embedded! Thanks it looks great!
