Here's all you have to do to add clustering to your node.js application.

save this code as cluster.js, and run cluster.js instead of server.js (or /bin/www, or whatever it's called for your project)
the only line you'll need to change is the last line - it needs to point to the location of your server.js file

var cluster = require('cluster');

if (cluster.isMaster) {
  // Count the machine's CPUs
 var cpuCount = require('os').cpus().length;

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

##Create an alias to MAMP's PHP installation

To do this, we can simply create an alias for our bash profile. We'll be doing this is nano, though you can do it in vim or a number of other editors as well.

Within the terminal, run:

nano ~/.bash_profile

This will open nano with the contents, at the top in a blank line add the following line:
