// Decay class, to call a callback less and less often. For example,
// make an Ajax request and freshen the decay only if the request has changed.
//
// To start the timeouts, call decay_object.start()
// To freshen up the speed of query, call decay_object.reset()
//
// Options:
// - seconds: time between each callback at the start and after a reset() (default 2)
// - decay: multiplier to use after each callback call (default 1.3)
// - max: maximum number of seconds to wait between each call (default 42)

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...
