bash helper function to make debugging node cli programs easier.
node-debug () {
PROGRAM="$(which $1)" # make sure we get an absolute path for programs in PATH
shift # remove the original program argument
set -- "$PROGRAM" "$@" # prepend the program path
node --debug-brk $@ & # start node in paused debug mode, send to background
node-inspector # start node inspector
kill %% # kill the background task (if still running)

Very small IE detect (aka type coersion ftw)
// ----------------------------------------------------------
// A short snippet for detecting versions of IE in JavaScript
// without resorting to user-agent sniffing
// ----------------------------------------------------------
// If you're not in IE (or IE version is less than 6) then:
// ie === 0
// If you're in IE (>=6) then you can determine which version:
// ie === 7; // IE7
// Thus, to detect IE:
// if (ie) {}

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...
