Hi,
At a recent Amsterdam Clojure Meetup, we were looking into transducers.
We could not find any situation where the "zero arity" println would get
called when using this futile transducer:
(defn println-transducing-fn
[reducing-fn]
(fn new-reducing-fn
([]
(println "zero arity")

Hi all,
I wrote a web app where you can play a card game with Clojure,
ClojureScript and Datomic.
Background on the design is here:
http://thegeez.net/2014/06/12/gin_datomic.html
The game is playable here: http://gin.thegeez.net/
The code is on github: https://github.com/thegeez/gin

Hi all,
I've released a Clojure web application. It includes a front-end using
DataScript and React.js in ClojureScript.
More details here:
http://thegeez.net/2014/04/30/datascript_clojure_web_app.html
The code is on github: https://github.com/thegeez/clj-crud
Demo on heroku: http://clj-crud.
Untested of course, but I think you need to use either :body or
:form-params rather than :query-params to put the query-params data into
the body of the post request.

Hi,
The solution is to explicitly require goog.fx.DragDrop in the :require
in the ns declaration:
[goog.fx.DragDrop :as dd-import]
This adds this line in the generated js output:
goog.require('goog.fx.DragDrop');
This line is required because DragDrop lives in its own file within

Hi,
I have run into a similar problem. The problem is something with the
"require" and namespaces in JavaScript. The following worked for me:
(ns example.example
(:require [goog.fx.Dragger :as unused-alias]))
And then to call the Dragger constructor:
(goog.fx.Dragger. )

Yes, my suggestion without type indicators in SDB would look something
like this:

Hi,
I have dabbled a bit with both AWS SimpleDB and the sdb library as
well as with the similar Google App Engine Datastore and related
Clojure libraries.
These two parts are indeed no-brainers:
- Support for consistent reads
- Support for literal string queries

Hi Alex,
Glad to be of help. I had never heard of FatJar before and it turned
out to work great for a clojure project I needed to distribute.
Also, as a fellow Dutch clojurian I can recommend the Amsterdam
Clojurians group at http://ams-clj.github.com.
Cheers,
Gijs

Perhaps it is a typo but you should have

Indeed I was not using the transients correctly. Transients are not
designed to be bashed in-place. (http://clojure.org/transients)
The gist is updated with a version that first worked without the
transients and then had the transient operations added. (https://

The problem is not the freqs function. The implementation in Python

Both produce a graph with the number of blocks per layer per type, for
6 particular types. These six types are the Clay, Coal ore, Diamond
