Travel Guide to OpenGL

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

OpenGL can be a bitch if you don't know what you're doing.
There is no worse pain than to experience CMake without knowing what you're doing.
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.

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

Multiple SSH Keys settings for different github account

create different public key

create different ssh key according the article Mac Set-Up Git

$ ssh-keygen -t rsa -C "[email protected]"

MySQL

Getting started:

	// place the code at the beginning of your script file
	// before any other use of 'require'
	const Module = require('module').Module;
	const originalLoad = Module._load;

	Module._load = function (name, parent) {
	const uid = `${parent} -> ${name}`;
	console.time(uid);
	const exports = originalLoad.apply(Module, arguments);
	console.timeEnd(uid);

	const {app, BrowserWindow} = require('electron')
	const path = require('path')
	const url = require('url')

	let window = null

	// Wait until the app is ready
	app.once('ready', () => {
	// Create a new window
	window = new BrowserWindow({

	import customModuleLoader = require('module');

	export class CustomModuleLoader {
	public cOptions: any = require('../tsconfig.json').compilerOptions;

	public replacePaths: any = {};

	constructor() {
	Object.keys(this.cOptions.paths).forEach(alias => {
	this.replacePaths[alias.replace(/\.?/, '(.)')] = this.cOptions.paths[alias][0].replace(/\*.?/, '$1');

	const exec = require('child_process').execSync;
	const path = require('path');

	module.exports = ({registry, pkgName, pkgVersion, cwd = process.cwd()}) => {
	const url = `${registry}/${pkgName}/download/${pkgName}-${pkgVersion}.tgz`;
	exec(`echo ${url} \| xargs curl \| tar -xz`, {
	cwd,
	});
	return path.join(cwd, 'package');
	}

	/**
	* 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)) {

	// takes a {} object and returns a FormData object
	var objectToFormData = function(obj, form, namespace) {

	var fd = form \|\| new FormData();
	var formKey;

	for(var property in obj) {
	if(obj.hasOwnProperty(property)) {

	if(namespace) {
