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

Remove WordPress full size images from being inserted into a post + option to and add max size to to prevent users from inserting massive images.
<?php
/**
*
* This removes the ability to add the FULL image size into a post, it does not alter or delete the image
* Add whataever extra image sizes to the insert dropdown in WordPress you create via add_image_size
*
* For now we have to do it this way to make the labels translatable, see trac ref below.
*
* If your theme has $content_width GLOBAL make sure and remove it
