Is there something obvious I am missing when aset in clojure 1.3-alpha8
won't work for shorts. aset-shorts does work, but way slower than I'd
expect. There is also an order of magnitude difference in speed between aset
^ints and aset-int.
I've looked at the source of amap (which was the first t
Incanter does. Works fine, but I'm not sure how fast it is.

I ran into this when creating a log4j appender in Clojure. I extended
the AppenderSkeleton, an abstract class. This abstract class
implements Appender. Appender defines two methods that don't appear
in the AbstractSkeleton (requiresLayout & close). I was able to
compile the Clojure class, withou

I also ran into this recently - doing the exact same thing (a log4j
appender). I was a bit surprised and I wonder if Clojure is
effectively generating abstract classes rather than concrete classes?
(Do we have no way to specify the difference? Is that only an artifact
of the Java compiler, not the
Not sure if I understand your problem.
Is it the verbosity of extracting coordinates? (rect-one :x1)
Or is the problem with increasing the dimensionality?
Anyhow I would define the types as following:
(def point [1 2 3])
(def rect [point point])
(defn point-in-rect? [p [[r1 r2]]]

Thanks for the help, appreciated! It helped me figuring out where exactly
things go haywire.
This works:

Aren't your statements [1] and [2] contradictory? Did you mean "more
idiomatic" perhaps in [1], or "more functional"
I think he meant that vectors of primitives are more efficient than normal
vectors.

More efficient than vectors of non-primitives, one imagines. Or, more
efficient than primitive vectors before 1.3 (I'm not sure if primitive
vectors exist in 1.2).

The documentation on records seems to indicate that they be used in
place of structs, but is there any advantage to using a record if no
protocols are assigned to it?
For example, I've defined a TcpServer record as part of a library I'm
developing:
(defrecord TcpServer
[port

Access to a record's in-definition members should be faster than
access
Hi, I've seen that one of the biggest speed bumps on the path to
delivering an Android application written in Clojure is app startup
time.
Has anyone tried writing the application's initial activity in pure
java and delegating the loading of clojure to a service? Perhaps the
service could send a
I need more details about how to install the current version of
clojure-mode. When I do alt-x package-install and type clojure-mode I
get a bunch of messages that it is compiling clojure-mode 1.7.1.
The website said to install clojure-mode via marmalade, but it's not
at all clear to me what marma
I started a thread on the Leiningen mailing list about improving
support for dependencies with native components, but I realized I
should have put it on the main Clojure list instead for a wider
audience:

Heh, yeah that marmelade was a funny one, I spent a few hours figuring what
goes where.
I suggest you download emacs-starter-kit from Phil's github repo, that has
the necessary configuration for marmelade too.
Then proceed with installing clojure-mode.

Then you might wanna double check whether you have the latest version (of
emacs-starter-kit), as it worked for me with a week old snapshot. (Im on
Mac, running Aquamacs).

Hi,
you might want to ask this on the counterclockwise mailing list:
https://groups.google.com/forum/#!forum/clojuredev-devel
That help Laurent to keep track of such issues.
