"How do I get started with Node?" is a commonly heard question in #Node.js. This gist is an attempt to compile some of the answers to that question. It's a perpetual work-in-progress.

And if this list didn't quite answer your questions, I'm available for tutoring and code review! A donation is also welcome :)

Setting expectations

Before you get started learning about JavaScript and Node.js, there's one very important article you need to read: Teach Yourself Programming in Ten Years.

Understand that it's going to take time to learn Node.js, just like it would take time to learn any other specialized topic - and that you're not going to learn effectively just by reading things, or following tutorials or courses. _Get out there and build things!

Improve Fonts

Newest

Make your Arch fonts beautiful easily! This is what I do when I install Arch Linux to improve the fonts.

You may consider the following settings to improve your fonts for system-wide usage without installing a patched font library packages (eg. Infinality):

Install some fonts, for example:
sudo pacman -S ttf-dejavu ttf-liberation noto-fonts

Disclaimer: Please follow this guide being aware of the fact that I'm not an expert regarding the things outlined below, however I made my best attempt. A few people in IRC confirmed it worked for them and the results looked acceptable.

Attention: After following all the steps run gdk-pixbuf-query-loaders --update-cache as root, this prevents various gdk-related bugs that have been reported in the last few hours. Symptoms are varied, and for Cinnamon the DE fails to start entirely while for XFCE the icon theme seemingly can't be changed anymore etc.

Check the gist's comments for any further tips and instructions, especially if you are running into problems!

How To Install Linux, Apache, MySQL, PHP (LAMP) stack on Ubuntu 12.04

About Lemp

LAMP stack is a group of open source software used to get web servers up and running. The acronym stands for Linux, Apache, MySQL, and PHP. Since the virtual private server is already running Ubuntu, the linux part is taken care of. Here is how to install the rest.

If any existing lamp installation & you need to upgrade your old server, uninstall all things & backup first all databases & files.

sudo apt-get purge php5*

	#!/bin/sh
	# Borrowed from http://marcparadise.com/blog/2013/09/21/how-to-fix-a-corrupt-history-file/
	# If you ever see a message like this upon starting a new shell
	# zsh: corrupt history file /home/marc/.zsh_history
	# here is a quick fix
	cd ~
	mv .zsh_history .zsh_history_bad
	strings .zsh_history_bad > .zsh_history
	# And reload history
	fc -R .zsh_history

	METHOD 1

	This should roughly sort the items on distance in MySQL, and should work in SQLite.
	If you need to sort them preciser, you could try using the Pythagorean theorem (a^2 + b^2 = c^2) to get the exact distance.

	SELECT *
	FROM table
	ORDER BY ((lat-$user_lat)(lat-$user_lat)) + ((lng - $user_lng)(lng - $user_lng)) ASC

	# This versions uses ELB loadbalancing
	# The ELB points to these two HAProxy hosts
	# The C-name of the Domain points to the ELB
	# ELB -> HAPROXY 1 or 2 -> Varnish --> HIT or MISS --> HAPROXY 1 or 2 -> Backend 1/2/3
	vcl 4.0;
	import directors;
	backend haproxy1 {
	.host = "172.31.xx.235"; # back to HAPROXY-1 internal address
	.port = "8080";
	.probe = {

	# The initial version
	if [ ! -f .env ]
	then
	export $(cat .env \| xargs)
	fi

	# My favorite from the comments. Thanks @richarddewit & others!
