two Perlin noise generators in javascript. The simplex version is about 10% faster (in Chrome at least, haven't tried other browsers)

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...

Get a Github OAuth token from the CLI with curl

At the command line:

curl -u ':USERNAME' -d '{"scopes":["public_repo"],"note":"Google Issues to GH"}' https://api.github.com/authorizations
curl -H "Authorization: bearer :TOKEN" https://api.github.com/users/:USERNAME -I

Replace :USERNAME with your Github username and :TOKEN with the oauth token you get from first curl

After that, the token will be listed in your Applications and you can revoke it from there
