Metadata in PDF files can be stored in at least two places:

• the Info Dictionary, a limited set of key/value pairs
• XMP packets, which contain RDF statements expressed as XML

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.

Possible solutions

// CSS Color Names
// Compiled by @bobspace.
//
// A javascript object containing all of the color names listed in the CSS Spec.
// This used to be a big array, but the hex values are useful too, so now it's an object.
// If you need the names as an array use Object.keys, but you already knew that!
// 
// The full list can be found here: https://www.w3schools.com/cssref/css_colors.asp
// Use it as you please, 'cuz you can't, like, own a color, man.

A Brief Introduction to Fabric

Fabric is a deployment management framework written in Python which makes remotely managing multiple servers incredibly easy. If you've ever had to issue a change to a group servers, this should look pretty familiar:

for s in $(cat servers.txt); do ssh $s service httpd graceful; done

Fabric improves on this process by providing a suite of functions to run commands on the servers, as well as a number of other features which just aren't possible in a simple for loop. While a working knowledge of Python is helpful when using Fabric, it certainly isn't necessary. This tutorial will cover the steps necessary to get started with the framework and introduce how it can be used to improve on administering groups of servers.

// This is a quick demonstration of "function inheritance" as described in
// this paper from Daniel Brown and William Cook.
// http://www.cs.utexas.edu/users/wcook/Drafts/2009/sblp09-memo-mixins.pdf
// Expressed in TypeScript (and without the monads).

// Syntax note: When you write function types in TypeScript, you need to name
// each parameter. But the names don't actually matter, so I just use _. You
// can read `(_:A) => B` as `a -> b` in ML or Haskell syntax.

// In Brown and Cook's Haskell, `type Gen a = a -> a` is a "generator." The
