Let's say you're using Ubuntu 13.04 (Raring Ringtail, released in April 2013) and it just went End-of-Life on you, because it's supported for only 6 months, and the deprecated packages are taken down after 12 months.

You'll probably figure this out the hard way. When you run sudo apt-get update, it will eventually report these errors:

The introduction to Reactive Programming you've been missing

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

This is an example of how to scaffold API endpoints to list / get / create / update / delete Posts in a Keystone website.

It's a modification of the default project created with the yo keystone generator (see https://github.com/JedWatson/generator-keystone)

Gists don't let you specify full paths, so in the project structure the files would be:

routes-index.js        -->    /routes/index.js         // modified to add the api endpoints
routes-api-posts.js    -->    /routes/api/posts.js     // new file containing the Post API route controllers

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.
