Hi all,
I'm writing a c10k-style service, i.e. suppose 10,000 concurrent
connections, mostly IO-bound. Clojure agents with `send-off` are
fantastically close to what I want conceptually, but I'm curious about the
implementation details--can anyone confirm, this would end up forking

One project I've considered porting is highly OO, with a large number of
classes and several levels of inheritance. In Common Lisp, I'd just use
CLOS. What methodology would be good to translate such a project to
clojure, while maintaining heavy reuse of inherited behavior and
abstraction?
Hi DavidM and ClojureCLR users,
In ClojureCLR built using .NET 3.5 framework, with-open needs some help
finding the .Dispose method on IDisposable objects:
It occurs when calling with-open on RegistryKey and System.IO.BinaryWriter
instances.
Here's the code snippet demonstrating this:
send-off works by submitting a Runnable to a newCachedThreadPool.
http://stackoverflow.com/questions/11316737/managing-agent-thread-pools-in-clojure
A Runnable sent to a thread pool will have exclusive use of that
thread until it completes; therefore, greater concurrency can only be
achieved by

I have listened to Rich's presentation Simple Made Easy, and he has

If you somehow missed the Conj, fear not! You can still attend a Clojure
conference soon!

Portland, Oregon. We will be using the Gerding Theater at the Armory as our
venue. Some portions of the conference will be single track
Hi
I would only add, that with Clojure 1.5 you can supply your own Executor
using (send-via ), the default threadpools are not hard-wired anymore.

Dear All,
I am trying to make sense of Closure by reading the book Programming
Closure, 2nd Eddition.
I persistently get booed at one of the very first lines of code in the book:
(conj coll item)
The listing (rather short) is below.
May I please ask you for some hint because beginner's luck
Hi Milen,
The function `conj` conjoins an item into a Clojure collection. In your
case, you need to define both `coll` and `item` for the example to work.
Consider these examples -
(conj [1 2 3] 4)
(conj '(1 2 3) 4)
(conj #{1 2 3} 4)
(def coll [1 2 3 4 5])
(def item 6)
(conj coll item)
etc.
The syntax for defrecord literals and tagged literals is very similar.
user (defrecord x [y])
user.x
user #user.x[3]
#user.x{:y 3}
user #user.x [3]
RuntimeException Unreadable constructor form starting with #user.x
clojure.lang.Util.runtimeException (Util.java:170)
[3]
Basically the
Use abstractions, forget inheritance.
Try modeling what the program does in terms of data conversion.
Then you will only need functions and data.

Ahmed,
You're grossly underestimating the effort needed to accomplish something
like that.
Why don't you look at your Clojure code and figure out ways of optimizing
that instead?

By slow speed, do you mean startup/compilation time or execution time

For the record, I point out that its not a bug specifically because
