Hi Alex,
Just one more thing to think about: Dmitry Groshev has been doing some good
early work on Clojure float support in the core.matrix NDArray
implementation (basically a NumPy-style multidimensional array
implementation backed by a single large float[] array).
The per-object overhead is

Seriously? Your problem is that a contributor has to state that they

Nicola Mometto also deserves quite a bit of credit, the fact that
tools.reader emits line and column information on all symbols is essential
for the accuracy of ClojureScript source maps.

Yeah, tools.reader is amazing. Honestly the source map patch was just a bit
of glue between David's existing work and integrating tools.reader, the
bulk of the results are due to them.

Hi Mikera,
I don't have a whole lot of skin in this game as, unfortunately, I
haven't run into any performance bottlenecks that I couldn't fix in a
satisfying way whilst writing Clojure.
My impression, however, is that there are some people in the community
who feel the performance limitations of
I just wanted to let everyone know that Metadata Partners (the company behind
Datomic) and I have merged with Relevance, Inc., to form Cognitect, Inc. This
merger is great for Clojure, adding considerable resources and stability to its
development and support, including new enterprise support of
Rich and Relevance,
This is very exciting news for the Clojure community (and yourselves
I'm sure). I for one look forward to seeing how you rock our worlds.

Dear List,
I'm experiencing a memory leak and I don't understand why.
I have a bunch of 50 files on disk called "data-1.edn" through
"data-50.edn". I perform the following code:
(def all-processed-data (reduce (fn [ret f] (merge ret (process-data
(clojure.tools.reader.edn/read-string (slurp f)
That is along the lines of my thinking. I am starting to look at zippers
again. However much of what I need it to do either isn't documented at all
or it was never intended to construct trees over time.
The purpose of this is to look at sequenced events and detect frequent
patterns. These patte

Use goog.string.format.

A symptom of this would be jmap or visualvm reporting [C or char[] as the
largest allocation, by class.

Offhand, I'd say this sounds like you need to build a Bayesian network.
I'd recommend taking this course:

which uses this book:

Thanks. I authored a paper on building a gaussian-bayes classifier and
implemented it in clojure. I looked at Titan. That has a lot of things I
like but it requires named nodes to only exist once. So, that is close but
not quite what I want. I'm looking at Zippers again.

Howdy,
I'm using core.async and ClojureScript and I'm running into a weird
problem... basically if/when/loop constructs don't work anymore in go
blocks in ClojureScript. For example:

Howdy,
I'm using core.async and ClojureScript and it seems that inside a go block,
if/when/loop/while code is never executed.
For example:
(def dog33 (go (if true (.log js/console "it's true") (.log js/console
"it's false"
prints neither "it's true" nor "it's false", but
(def dog33 (go
Timothy, thank you very much for such a good explanation! I fully agree
with you. Actually, except for a few details, that is really how I thought
the things are. It is good that you describe the technical base for
problems with the issue. As well as clearified the human factor. What
you're saying
Which versions of ClojureScript and core.async are you using?

I find your description interesting but I'm confused about what the actual
underlying problem is- is indexing and searching for data in documents
involved, or is that just an example? If the real problem is about

If you're worried about NIO buffer marshalling, Vertigo [1] lets you treat
them as native Clojure data structures. This doesn't save you from the
float<->double coercion for arithmetic operations, but as James said
earlier in the thread, this tends to be insignificant. However, if you're

Won't work you need core.async master. The next core.async release will fix
the issue.

You can always fork Clojure and patch IFn.java and Compiler.java to support
floats for at least some types of functions. It probably won't be so hard.
As your case is a very specific one, this may be a viable solution.
