Thanks for your suggestions!
I think decompiling and altering the class is probably a little bit
beyond my skill level. At first I tried to start a swank server from
my servlet, but that failed because GAE doesn't allow you to open
sockets. By decompiling and disabling that, I could probably

Been discovering clojure, and I have a working slime up and running,

One thing I have not managed to get working is the completion.

Hi everyone,
Trying to set up a new project using enclojure. I created the new project,
then put a new .clj file in Project Sources. In that file, I typed:
(defn main [] (print hi))
...which works in a REPL. But when I try to build the project, I get a big
old stack trace
Hi there,
I'm working on a project that involves transferring large files over
the network (100+MB) and wondering what would work better. I'm newer
to Java than I am to lisp, so I've just grabbed the most obvious
things from the API that I thought could possibly work:
(ns misc-ports

It looks like you're reading one byte at a time. Why not create a buffer and
read up to 1024 bytes at a time?
(defn write-file [ins outs]
(let [buffer (make-array Byte/TYPE 1024)]
(loop [len (.read ins buffer)]
(if (not (neg? len))
(do
(.write outs buffer 0 len)

Consider using the new I/O API's in java.nio.*
From http://java.sun.com/j2se/1.5.0/docs/guide/nio :
The new I/O (NIO) APIs introduced in v 1.4

You could also wrap your input and output stream's with
java.util.zip.GZIPInputStream and GZIPOutputStream to
compress/decompress the data either side. They allow you to specify
buffer sizes, so you could

Nice!
I had to learn a bit about jogl to get it to work - had to add -

The following is in model.clj:
(defn update [ref val]
(when (not (= @ref val)) (dosync (ref-set ref val

What are the use case scenarios where one is preferable to the other
in clojure ?
It looks to me like vectors almost completely overtake lists for all
purposes.

I'm no expert, but I think this explain some:
Clojure's conj function is like Lisp's cons, but does the right
thing, depending on the data type. It is fast to add something to
the front of the list, and slower to add something to the end.
Vectors are the opposite, you can add to the end fast,
And here are some numbers from my machine:
(def my-list (list 'a 'b 'c 'd 'e 'f 'g 'h 'i 'j))
(def my-vector ['a 'b 'c 'd 'e 'f 'g 'h 'i 'j])
; ~44ms
(time (dotimes [x 100]
(conj my-list 'k)))
; ~26ms
(time (dotimes [x 100]
(pop my-list)))
; ~100ms
(time (dotimes [x 100]

I think that's a fair statement.
Lists are still:
- key as the data structure that represents a call (to a function,
macro, or special form)
- useful for
I'm not a java security manager expert, but I've been playing with this a

Could you not do it the other way round? Start a REPL and run the server in
the REPL, instead of starting a server and trying to run a REPL in the
server?
I got as far as setting up the classpath and doing:
