Hi,
Iam trying to run a function in a thread assuming that threads are
runnable, below is my program i want to print 4 time the current date
(defn- on-thread [f]
(doto (Thread. #^Runnable f)
(.start)))
(defn prnTime [] (prn (System/currentTimeMillis)))
(defn r4t [f]
(d
Hi, foop
Your error in this line:
(r4t (on-thread (prnTime)))
You pass to function r4t thread instead of functions. Because
(on-thread (prnTime)) returns thread
You must pass #(on-thread (prnTime)) instead

Nikita Beloglazov

thank you for the reply, is there any way to close this 4 threads
after the job is done?

What do you mean "close threads"?
As I know threads aren't supposed to be closed. There is no mechanism to do
this. They are not connections or smth like that.

Are there any good .NET books you guys could recommend? I'm looking
for a range of resources. I don't need "C# in 21 days" or "C# for
dummies", but something an experienced Java hacker could start out
with, similar to Core Java. Also, a more advanced book so I could
learn to follow the ClojureCL
In addition to that, prnTime should have no parens:
#(on-thread prnTime)
As it was, prnTime was running before going into on-thread, which was
acting on a runnable that's nil (the return value of prn). The
difference between the two can be seen in the output. When prnTime
runs inside the threads,
Hi Nikita,
Your function works! Could you explain the "->>" a bit? Thanks, -

Hi Dave,
There are really 2 functions, -> and ->>

Sometimes you need to perform several functions on after another. You can
write something like
(func1 (func2 (func3 value)))
But you also can write like:
(-> value
(func3)
(func2)
(func1))
It takes value, insert it into (func1) form a
Awesome! Thank you so much for your help -- I really appreciate it.

I have a server which loads some compiled classes/functions then
starts accepting requests and handing them off onto a thread pool for
processing.
No problem - so far...
One of the requests allows the passing and evaluation of an arbitrary
piece of clojure.
This is causing me to lose hair !

We have a ten-week program for experienced developers moving to
the .NET platform. Our recommended text is Troelson's "Pro C# 2010
and the .NET 4 Platform, Fifth Edition".

All 1752 pages of it.

I having some trouble with system calls using clojure (actually a
whole lot more than that but this is the current day's difficulty).
Below, test-execute works, but get-msms-pts-OSX seems to hang, as in
nothing happens and the REPL is unresponsive afterwards. If I run the
output of the (str **

Also, this only shows the 2nd call (with ls-arg2):
(defn test-execute [ls-arg1 ls-arg2]
(execute (str "ls -" ls-arg1))

so maybe the difficulty above is some problem with how the multiple
system calls are performed. If I only use this:

Anyone using lein-deamon and have success getting it working? When trying

java.lang.IllegalArgumentException:

You may have a path problem.
Try running "env" in the same fashion - I get a very basic path (just
"/bin" and "/usr/bin") and none of

Correction - there is: (into-array String ["a" "b"])
