	Passenger is a way of running Node.js~~, Ruby on Rails (RoR),~~ and other applications that normally require a constantly running background process. Instead of the process always running in the background just waiting for connections, Passenger shuts it down if there are no connections. When someone visits the website, Passenger fires up the Node.js (or Ruby, or whatever language you're using) process. If another person visits the website while the Node.js process is still running, page loads will be very fast. If there are no further page hits for 5 minutes or so, Passenger kills the background process.

	Express.js is a web application framework for [[:Node.js\|Node.js]]. It provides a set of tools and features to build web applications and APIs quickly and easily. Express.js simplifies common tasks like routing, handling HTTP requests and responses, setting up middleware, and managing sessions. It is lightweight and flexible, allowing developers to structure their applications as they see fit. It is commonly used for building RESTful APIs or server-side applications.

	It doesn't make sense to leave your car running 24/7 in front of your house just in case you need to drive somewhere so it saves you a second to start the engine. This is a massive waste of gas.
