Yup you're right, CCW "typed" that, you may disable that feature from

I knew that comute would rerun before the commit,but my problem is
that if we allow ref-set ref after commuting,it seems there is no bad
thing would happen.What's the purpose of this limitation except alter
or ref-set have no lasting result?

Hey Dennis,
I suggested some of the same ideas here (http://tech.puredanger.com/
2010/06/08/clojure-agent-thread-pools/) and Rich said that these
seemed like good suggestions post-1.2. I think allowing you to modify
the agent thread pools after construction seems possibly dangerous

Hi,
when I "Run as Clojure Repl" the next little source file:
(ns test.readln)
(defn -main []
(println "Enter some text for the first time:")
(println (read-line))
(println "Enter some text for the second time:")
(println (read-line)))
(-main)
I get the follo

How are you accessing the authorization url? If by hand you mean you

Did you go to the authorization

that error typically means the user didn't

Randy, thanks for the reply. This has certainly cleared things up for
me.
I was only concerned about performance for an order of magnitude or
more; just checking I was on the right track, so to speak.
It seems I'll have to do a little research on transients now.

Thx guys!
I used double-buffering like in Ryan's code and it worked like a
charm!

This is a wholly appropriate use of reduce; it's the obvious function
to use when you want to "accumulate" some calculation over a sequence.
As you say, you can just produce a function that acts on the result,
something like
(defn fstep [c] (if (= c \<) pop #(conj % c))
However, the obvious way

Even the "TEST" Problem will TLE!!!
My code is here:
(ns spoj-test)
(defn read-int
[]
(let [s (read-line)]
(Integer/parseInt s)))
(defn main
[] (let [n (read-int)]
(when (not (== 42 n))
(println n)
(recur
(main)
the sample input is OK.

HI,
You'd be best served overriding the JPanel's paint or paintComponent
method (I'm fuzzy on the difference), and then calling repaint
periodically (at your desired frame rate). IIRC, repaint is safe to
call from any thread, and it will cause the paint methods to be called
in the swing thread.
I've been working on a game with Clojure/Swing lately and the simplest
way to avoid flashing is to draw to a bufferedImage first, then draw
that bufferedImage all at once. This means that parts of the screen
that don't change won't be briefly overwritten by the background
color, avoiding flashing.
I have a simple string (or list of characters to be precise) in a form
of: "1234<5678<<9".
I want to parse this string and end up with: "123569".
The "<" is essentially the same as a "backspace".
I managed to implement this fairly simply using the reduce function -

Well obviously if you can get something to be tail-recursive you won't have
the stack overflows, and the thing in your code that prevents tail recursion
is having to cons the result of the recursive call. So let's try this:
(defn remove-first
[syb lst]
(let [[before after]
(loop [b [

Really like that solution.

Read the documentation of commute carefully:
http://richhickey.github.com/clojure/clojure.core-api.html#clojure.core/commute
commute acts at the end of the current dosync-block, regardless of
when commute was applied inside it. That's the reason why you can't
ref-set it after a commute; the commut
Agent use two thread pools to execute actions,send use a fixed thread
pool (2+cpus threads),and send-off use a cached thread pool.These
pools are global in clojure system.
I think the Agent should allow users to customize the thread pool,
if no custom, then use the global thread pool.
Why
Alter or ref-set a ref after commute would throw a
IllegalStateException:Can't set after commute
for example:
user=> (def counter (ref 0))
#'user/counter
(dosync (commute counter inc) (ref-set counter 3))
java.lang.IllegalStateException: Can't set after commute
(NO_SOURCE_FILE:0)
