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

/**
 * test if the target is an object(array included)
 */
export function isObject(obj: any): boolean {
  return obj !== null && typeof obj === 'object';
}

/** simple deep equal */
export function isEqual(a: any, b: any): boolean {
  if (isObject(a) && isObject(b)) {

Travel Guide to OpenGL

I've figured out several things while trying to extend my knowledge of Computer Graphics.

1. OpenGL can be a bitch if you don't know what you're doing.
2. There is no worse pain than to experience CMake without knowing what you're doing.
3. When walking to the depths of hell, it would be nice to have a travel guide.

And that's what this is, a travel guide.
