Clojure, Haskell and OCaml implementations of the same algorithm, which is a negative space finder for a very constrained situation involving nested rectangles. For those interested in a more comprehensive take on these relationships (using scheme rather than clojure), see: http://lambda.jimpryor.net/translating_between_ocaml_scheme_and_haskell/
(def parent {:x1 0 :y1 0 :x2 600 :y2 400})
(def rs [{:x1 0 :y1 0 :x2 300 :y2 200 }
{:x1 0 :y1 200 :x2 300 :y2 400 }])
(defn negative-space [parent rs]
(let [x (apply max (map :x2 rs))
y (apply min (map :y1 (filter (comp (partial = x) :x2) rs)))]
{:x1 x :y1 y :x2 (parent :x2) :y2 (parent :y2)}))
(negative-space parent rs)

Use one of these techniques to install node and npm without having to sudo. Discussed in more detail at http://joyeur.com/2010/12/10/installing-node-and-npm/ Note: npm >=0.3 is *safer* when using sudo.
echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrc
. ~/.bashrc
mkdir ~/local
mkdir ~/node-latest-install
cd ~/node-latest-install
curl http://nodejs.org/dist/node-latest.tar.gz | tar xz --strip-components=1
./configure --prefix=~/local
make install # ok, fine, this step probably takes more than 30 seconds...
curl https://www.npmjs.org/install.sh | sh
