I decided to start with the BeagleBone Black as the embedded controller,

So, the first thing I need to do is make sure that I can get the I2C

Another plus on the ClojureScript side (long term) might be execution
speed. I recently watched a Clojure Conj 2012 presentation by
Another possible approach could be use clojurescript to a nodejs target.
From some cursory googling, there do seem to be node modules like

And I believe you might also get a better startup time.

Hi all,
While building the API for core.matrix, I've fun into a few cases where the

Examples are +, zero?, vector?, ==
In many of these cases, the core.matrix behaviour is a natural extension of
the clojure.core function (i.e. it extends the same
It is probably instructive to look at how (use-primitive-operators) works

basic mechanism is pretty simple: use 'ns-unmap' to get rid of the
operators you want to shadow, and bring in the operators from the alternate
Hmmm clever trick. I hadn't thought about hijacking ns :-)
Still, it's a colossal hack. Monkey patching always makes me feel uneasy.
Perhaps Clojure itself needs patching to make this use case a bit more
palatable? Some obvious options:

You only get the warning if you 'use' the namespace or 'refer all'

Maybe this is a dumb idea, but could you have a macro that rewrites code to
