While doing image processing in Clojure recently it occured to me that it
would be handy to have a specifier suffix for distinguishing between
doubles and floats as libraries in this domain often use single precision
floats instead of double precision (or mixtures of both).
My code frequently
It's really great that you are going to teach Clojure at BSU.
I have no clue about teaching, but my impression is that back in my days,
we didn't learn much about how to write good code.
Maybe things were different in 'informatics', but in 'applied mathematics',
for instance, we only had
Exciting times indeed!

With testing frameworks, there's nothing like trying all of them with a
medium-sized code base. I use both clojure.test and Midje for
clj-webdriver, but have recently used (and enjoyed) Expectations to test a

Midje is the most batteries-included of the three and provides
I agree that the current throw-on-duplicates behavior is broken, because it
renders literals with variable keys useless.

Hi all,
I'm pleased to announce the 0.5.3 release of clj-http. clj-http is an
idiomatic clojure http client wrapping the apache client (like ring in
reverse). You should be able to use it from Clojars[1] using leiningen
with the following:

That's a sequence of Float objects not a float[], just FYI.
As far as I can tell there's no way to do this with user code. I think it
would have to be done within the

I've been doing some programming exercises in Clojure, I've run into one I
don't know how to approach. If anyone can just give me the strategy to use
on this that'd be great. Here is the problem statement:
Given an array of ints, is it possible to choose a group of some of the
ints, such that

don't forget a base case.
watch your cpu heat very quickly up on even slightly longer lists.

sorry take the first# actually is meant to be worded as, in turn,
take out 1 of each of the #s, and recurse on what remains so that you
are doing the permutations at each level of the recursion/tree.

I thought of doing something like that, but part of the requirements is
that the sum could be achieved with *some of the numbers in the vector.

An additional step on top of Raoul's:
Take the first #, subtract it from the goal, recursively ask if the remaining
#s can sum to the now-lesser goal. If so, return yes, or the set of numbers
that worked (which should include whatever was returned from the recursive
call, plus the first #)
Thanks for all the help!

Hi Everyone... Quick question about Rich's latest talk:
