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

css3 image mask
I had a background image that I wanted to apply border-radius to-- which you can't do to a background image. masks to the rescue! I opted for a method that didn't require an image mask overlay.
radial gradient params: (x/y positioning, width/height, how sharp you want the edges to be, dont mess with last value)
-webkit-mask-box-image: -webkit-radial-gradient(19px 19px, 19px 19px, black 92%, transparent 100%)
